Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1 is a schematic structural diagram of an atomizer according to a first embodiment of the present invention, and fig. 2 is a perspective view of an atomizer according to a first embodiment of the present invention. The atomizer of the embodiment can be suitable for indoor or vehicle-mounted aromatherapy and other conditions. Referring to fig. 1 and 2, the atomizer specifically includes: a liquid storage device 10 for storing a liquid to be atomized; a gas driving device 20 for atomizing the liquid to be atomized stored in the liquid storage device 10; the liquid level detection device 30 is arranged in the liquid storage device 10 and is used for measuring and acquiring liquid level information of the liquid to be atomized stored in the liquid storage device 10 in real time; and a control device 40 electrically connected to the liquid level detection device 30 and the gas driving device 20, respectively, for controlling the power of the gas driving device 20 according to the liquid level information.
In this embodiment, the optional atomizer is an aromatherapy machine. The liquid storage device 10 of the atomizer can be a liquid storage bottle of the aromatherapy machine, and the liquid to be atomized stored in the liquid storage device 10 can be essential oil in the aromatherapy machine.
In this embodiment, the gas driving device 20 is used for atomizing the liquid to be atomized stored in the liquid storage device 10. Optionally, the process of atomizing essential oil by the gas driving device 20 is as follows: after the aromatherapy machine is electrified, the gas driving device 20 introduces air from the outside of the aromatherapy machine to form high-speed air flow and impact the surface of the essential oil, so that fine essential oil bubbles or essential oil gas are formed in the essential oil, and the essential oil in the liquid storage bottle of the aromatherapy machine is atomized; meanwhile, the air driving device 20 guides external air into the liquid storage bottle, so that the pressure in the liquid storage bottle is higher than the external pressure, and further the essential oil mist can be discharged out of the aromatherapy machine and diffused to the surrounding environment, thereby achieving the effect of releasing fragrance.
In this embodiment, the liquid level detection device 30 is disposed in the liquid storage device 10, and the liquid level detection device 30 can measure the liquid level of the liquid to be atomized in the liquid storage device 10 in real time. After the essential oil in the aromatherapy machine is atomized and diffused to the outside, the liquid level of the liquid to be atomized in the liquid storage device 10, namely the essential oil, is lowered, and the liquid level detection device 30 can measure the liquid level of the liquid to be atomized in the liquid storage device 10, namely the essential oil, in real time.
After the aromatherapy machine starts to work, the essential oil in the liquid storage bottle is continuously atomized and diffused to the outside by the gas driving device, so that the essential oil in the liquid storage bottle is continuously reduced, and the liquid level is continuously lowered. If the power of the gas driving device is kept constant, the mist output of the aromatherapy machine is possibly unstable along with the continuous reduction of the essential oil in the liquid storage bottle.
In this embodiment, the optional control device 40 is a single-chip microcomputer, and the control device 40 is used for controlling the power of the gas driving device 20 according to the liquid level information. The control device 40 is preset and stores a plurality of liquid level values, operating powers of the plurality of gas driving devices 20, and correspondence between the plurality of liquid level values and the operating powers of the plurality of gas driving devices 20, that is, each liquid level value stored in the control device 40 corresponds to the operating power of one gas driving device 20. When the control device 40 obtains the liquid level information of the liquid storage device 10 through the liquid level detection device 30, it can find out the working power corresponding to the liquid level information, and then control the gas driving device 20 to atomize the liquid according to the found working power. The control device 40 adjusts the working power of the gas driving device 20 according to the change of the liquid level, so that the stability of the mist output of the atomizer can be improved, and the phenomenon of unstable mist output caused by the constant power of the gas driving device of the conventional aromatherapy machine can be improved.
The number of liquid level values stored in the control device 40 is limited, and the liquid level change during the liquid atomization is continuous. The process of determining the working power corresponding to the liquid level information by the control device is optional, after the liquid level information is obtained by the liquid level detection device, the liquid level value closest to the liquid level information can be determined first, the closest liquid level value is determined as the target liquid level value corresponding to the liquid level information, and the working power corresponding to the target liquid level value stored in the control device is the target working power; the control device 40 controls the gas driving device 20 to operate in accordance with the target operating power. If the control device 40 determines that the level information corresponds to two closest level values, the control device 40 may randomly select one of the two closest level values as the target level value of the current level information.
Alternatively, the control device 40 may control the power of the gas drive device 20 by controlling the voltage across the gas drive device 20.
As described above, the working process of the atomizer provided in this embodiment is as follows: the gas driving device 20 introduces gas from the outside to form high-speed airflow to impact the liquid to be atomized, so that the liquid to be atomized is atomized, and meanwhile, the pressure in the liquid storage device 10 is increased, so that the gas mist is diffused to the outside; the liquid level detection device 30 in the liquid storage device 10 measures the liquid level of the liquid to be atomized in the liquid storage device 10 in real time, and the control device 40 controls the working power of the gas driving device 20 in the atomizer according to the liquid level information detected by the liquid level detection device 30, so that the speed of introducing air by the gas driving device 20 and the speed of atomizing the liquid to be atomized are changed, and the mist output of the atomizer is regulated. Alternatively, the operating frequency of the gas drive device 20 may be varied by adjusting the voltage of the gas drive device 20.
The atomizer provided by this embodiment includes: a liquid storage device 10 for storing a liquid to be atomized; a gas driving device 20 for atomizing the liquid to be atomized stored in the liquid storage device 10; the liquid level detection device 30 is arranged in the liquid storage device 10 and is used for measuring and acquiring liquid level information of the liquid to be atomized stored in the liquid storage device 10 in real time; and a control device 40 electrically connected with the liquid level detection device 30 and the gas driving device 20 respectively, and used for controlling the power of the gas driving device 20 according to the liquid level information. The working frequency of the gas driving device 20 is changed according to different liquid level height information of liquid to be atomized stored in the liquid storage device 10, so that the speed of air introduced by the gas driving device 20 and the speed of liquid to be atomized are changed, the mist outlet quantity of the atomizer is adjusted, the problem that the mist outlet quantity of the atomizer is unstable in the prior art is solved, the stable mist outlet quantity of the atomizer is realized, and the effect of uniform diffusion is achieved.

The capacitive liquid level sensor used in the embodiment may be a column, and may be optionally installed at an opening of the liquid storage device 10, where the column extends to the bottom of the liquid storage device 10.

Therefore, before the control device obtains the information of the liquid level of the liquid to be atomized stored in the liquid storage device, the control device is further used for: setting a standard consumption reference value, setting a 1 st liquid level interval to an mth liquid level interval, and determining the average working power of the ith liquid level interval for maintaining the standard consumption reference value as the basic power of the ith liquid level interval, wherein m is a positive integer, i=1, 2, … and m; and storing the corresponding relation between the m liquid level intervals, the m basic powers and the liquid level intervals and the basic powers.
For example, the total height of the liquid storage device 10 is set to be H, the standard consumption reference value is set, and the liquid storage device is divided into 5 liquid level sections, namely 1 st to 5 th liquid level sections, wherein the liquid level heights of the 1 st to 5 th liquid level sections are respectively 0H-0.2H, 0.2H-0.4H, 0.4H-0.6H, 0.6H-0.8H and 0.8H-1H.
When the control device detects that the liquid level height information belongs to a 1 st liquid level interval 0H-0.2H, the corresponding basic power is P1; when the control device detects that the liquid level height information belongs to the 2 nd liquid level interval 0.2H-0.4H, the corresponding basic power is P2; when the control device detects that the liquid level height information belongs to a 3 rd liquid level interval between 0.4H and 0.6H, the corresponding basic power is P3; when the control device detects that the liquid level height information belongs to the 4 th liquid level interval 0.6H-0.8H, the corresponding basic power is P4; when the control device detects that the liquid level information belongs to the range between 0.8H and 1H in the 5 th liquid level range, the corresponding basic power is P5.
The basic power corresponding to the ith liquid level interval may be selected as an average working power for maintaining the standard consumption reference value in the ith liquid level interval, that is, the atomizer may be tested before determining the basic power corresponding to each liquid level interval, and the control device 40 adjusts the working power of the gas driving device in real time according to different liquid level heights in each liquid level interval so as to maintain the consumption of the liquid to be atomized in the standard consumption reference value in unit time, and records each working power corresponding to maintaining the standard consumption reference value in different liquid level heights in each liquid level interval. And finally, the control device averages all the working powers recorded in the same liquid level interval to obtain average working power serving as the basic power in the liquid level interval.
For example, when the liquid level detection device detects that the liquid level information is 0.95H, the control device determines that the liquid level interval to which the liquid level detection device belongs is 0.8H-1H, and then determines the base power P5 corresponding to the 5 th liquid level interval as the target base power corresponding to the liquid level (0.95H).
It should be noted that, the liquid level interval corresponding to the target base power may be equally divided or unevenly divided, and those skilled in the art may perform other division according to actual needs.
Step S122, calculating liquid consumption information of the liquid to be atomized in unit time, and determining target compensation power according to the liquid consumption information of the liquid to be atomized.
The specific process is as follows: determining a target consumption interval of the liquid consumption information in the target liquid level interval according to the target liquid level interval of the liquid to be atomized and the liquid consumption information in unit time; the compensation power corresponding to the target consumption interval of the target liquid level interval is determined as the target compensation power of the gas driving device.
Wherein the information on consumption of the liquid to be atomized per unit time may be the consumption of the liquid to be atomized per unit time (e.g., 1 minute). Specifically, the consumption may be characterized by a consumption volume of the liquid to be atomized within 1min, for example, if the liquid storage device is cylindrical, the consumption volume of the liquid to be atomized may be obtained by a product of a drop height Δh of the liquid level in unit time and a bottom area S of the liquid storage device. One skilled in the art can attach that the shape of the reservoir means, including but not limited to a cylinder, is characterized by the consumed volume of the liquid to be atomized as a consumed quantity, and that the consumed quantity per unit time can be accurately determined when the reservoir means is of a regular or irregular shape.
Specifically, before the liquid level information of the liquid to be atomized stored in the liquid storage device is obtained, the method may further include: setting a 1 st consumption interval to an n th consumption interval, and for an i th liquid level interval, determining an average value of power increment adjusted from the j th consumption interval to a standard consumption reference value as compensation power of the i th liquid level interval in the j th consumption interval, wherein n is a positive integer, and j=1, 2, … and n; the control device stores n consumption intervals, m x n compensation powers and the corresponding relation between each liquid level interval and the compensation power in each consumption interval.
For example, 2 consumption sections are set, and the 1 st to 2 nd consumption sections are respectively 0 to 1mL and 1 to 2mL of liquid consumption volume per unit time. For example, in the 1 st liquid level interval of 0H-0.2H, the compensation powers set corresponding to the two consumption intervals are p11 and p12, respectively; in the 2 nd liquid level interval of 0.2H-0.4H, the compensation power corresponding to the two consumption intervals is p21 and p22 respectively; in the 3 rd liquid level interval of 0.4H-0.6H, the compensation power corresponding to the two consumption intervals is p31 and p32 respectively; in the 4 th liquid level interval of 0.6H-0.8H, the compensation power corresponding to the two consumption intervals is p41 and p42 respectively; in the 5 th liquid level interval of 0.8H-1H, the compensation powers corresponding to the two consumption intervals are p51 and p52 respectively. The standard consumption reference value is kept constant in any one of the liquid level intervals.
Wherein, in each liquid level interval, the compensation power corresponding to each consumption interval can be selected as the average value of the power increment adjusted from the j-th consumption interval to the standard consumption reference value. For example, in the 1 st liquid level interval, when the current liquid level interval is in the 1 st consumption interval, the control device adjusts the power of the gas driving device to enable the consumption value to approach or maintain the standard consumption reference value, and records a plurality of power parameters in the current 1 st consumption interval in real time, wherein the difference value between the average value of the power parameters and the basic power of the 1 st liquid level interval is the compensation power of the 1 st liquid level interval in the 1 st consumption interval.
Illustratively, assume that the standard consumption reference is 1mL. If the liquid level detected by the liquid level detection device is 0.95H and the liquid consumption volume is 0.4mL in 1 minute after calculation, the control device determines that the corresponding liquid level interval is the 5 th liquid level interval, namely the target basic power is P5, and determines that the 1 st consumption interval is the target consumption interval, and the compensation power of the 1 st consumption interval of the 5 th liquid level interval is P51.
It should be noted that, the liquid consumption intervals under different liquid level height intervals may be equally divided or unevenly divided, and the compensation powers corresponding to the same liquid consumption interval under different liquid level intervals may be the same or different, and the compensation powers need to be determined and calculated through experiments.
And step S123, determining the actual working power according to the target basic power and the target compensation power.
The control device can determine the actual working power after processing according to the obtained target basic power and the target compensation power. It should be noted that, in this embodiment, the compensation powers recorded in the control device may be positive values; when the consumption of the liquid to be atomized per unit time is equal to the standard consumption reference value, the target compensation power of the gas driving device can be selected to be 0.
Optionally, if the minimum value of the target consumption interval of the liquid to be atomized in the target liquid level interval is greater than the standard consumption reference value, determining the difference between the target base power and the target compensation power as the actual working power.
In this embodiment, when the minimum value of the target consumption interval is greater than the standard consumption reference value, it is indicated that the current consumption is greater than the standard consumption reference value, and the power of the gas driving device needs to be reduced to reduce the consumption at this time, so that subtracting the target compensation power from the target base power can reduce the power of the gas driving device, and the difference is used as the actual working power of the gas driving device.
Assuming that the liquid level detected by the liquid level detection device is 0.95H, the control device determines that the corresponding target basic power is P5, assuming that the liquid consumption is 1.5mL per minute in the 5 th liquid level interval, the target consumption interval to which the liquid consumption belongs is the 2 nd consumption interval, and the corresponding target compensation power is P52, and the actual working power determined by the control device is P5-P52.
Optionally, if the maximum value of the target consumption interval of the liquid to be atomized in the target liquid level interval is smaller than the standard consumption reference value, determining the sum of the target base power and the target compensation power as the actual working power.
In this embodiment, when the maximum value of the target consumption interval is smaller than the standard consumption reference value, it is indicated that the current consumption is smaller than the standard consumption reference value, and the power of the gas driving device needs to be increased to increase the consumption, so that adding the target base power to the target compensation power can increase the power of the gas driving device, and the sum is used as the actual working power of the gas driving device.
Assuming that the liquid level detected by the liquid level detection device is 0.75H, the control device determines that the corresponding target basic power is P4, assuming that the liquid consumption is 0.2mL per minute in the 4 th liquid level interval, the target consumption interval to which the liquid consumption belongs is the 1 st consumption interval, and the corresponding target compensation power is P41, and the actual power determined by the control device is p4+p41.
It should be noted that, to ensure the accuracy of the above technical solution, the standard consumption reference value is generally not selected to be the same as the maximum value or the minimum value of the consumption interval. Taking the set 2 consumption intervals as an example, the standard consumption reference value is 1mL, the 1 st consumption interval is specifically that the liquid consumption volume in unit time is greater than or equal to 0 and less than 1mL, and the 2 nd consumption interval is specifically that the liquid consumption volume in unit time is greater than 1mL and less than or equal to 2mL. The maximum value of 2mL in the 2 nd consumption interval is only an example, and in practice, the maximum value (2 mL in this example) in the maximum consumption interval is substantially equal to the maximum consumption amount of the nebulizer per unit time.
In the above technical solutions, it is assumed that the compensation power corresponding to each consumption interval is positive.
In other embodiments, the compensation power may have positive and negative values. Specifically, when the maximum value of the consumption interval is smaller than the standard consumption reference value, the consumption amount needs to be increased at the moment, namely, the power is increased on the basis of the basic power to obtain the actual working power, so that the compensation power corresponding to the consumption interval can be selected to be a positive value; when the minimum value of the consumption interval is larger than the standard consumption reference value, the consumption amount is required to be reduced at the moment, namely, the power is reduced on the basis of the basic power to obtain the actual working power, so that the compensation power corresponding to the consumption interval can be selected to be a negative value. The sum of the target base power and the target compensation power is taken as the actual operating power of the gas drive.
The control device adjusts the operating power of the gas drive device in the atomizer according to the above manner, which can be achieved by adjusting the voltage or current input to the gas drive device. After the power of the gas driving device changes, the speed of pumping air into the liquid storage device by the gas driving device also changes, so that the speed of atomizing liquid to be atomized and the speed of outward diffusion of atomized gas are changed, the purpose of dynamically adjusting the mist output of the atomizer is achieved, the mist output of the atomizer is kept uniform, and the change of the mist output caused by the drop of the liquid level of the liquid to be atomized is avoided.
The operating principle of the control method of the atomizer is as follows: the liquid level detection device detects the liquid level in the liquid storage device in real time, the control device determines target basic power corresponding to the liquid level information according to the liquid level information, then the control device calculates liquid consumption information in unit time, determines target compensation power corresponding to the liquid consumption information according to the liquid consumption information, and finally the control device determines actual working power according to the obtained target basic power and the target compensation power and applies the actual working power to the gas driving device of the atomizer. Specifically, if the gas driving device is a piezoelectric air pump, the working power of the piezoelectric air pump can be changed by changing the voltage of the piezoelectric air pump, so that the speed of pumping air by the piezoelectric air pump, the speed of atomizing liquid to be atomized and the diffusion speed of atomized gas are adjusted, and the technical effects of controlling the mist output of the atomizer in real time and keeping uniform mist output are achieved.
According to the technical scheme, the actual working power of the atomizer is determined according to the target liquid level interval and the target consumption interval under the target liquid level interval, and the vibration frequency of the piezoelectric air pump vibrating plate is changed by changing the power of the actual working of the atomizer, so that the contraction and expansion frequency of the piezoelectric air pump chamber is controlled, the speed of air pumped by the piezoelectric air pump and the speed of the liquid to be atomized by gas atomization are controlled, the mist outlet quantity of the atomizer is controlled, the problem that the mist outlet quantity of the atomizer is unstable in the prior art is solved, and the effects of guaranteeing the stable mist outlet quantity and uniform diffusion of the atomizer are achieved.

It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
