Referring to fig. 1, fig. 1 is a schematic diagram illustrating an application scenario and a structure of a respiratory mask according to an embodiment of the present application.

In the present embodiment, the respiratory mask 100 is applied to the respiratory apparatus 1000 and is connected to the respiratory line 200. The respiratory apparatus 1000 is a ventilation therapy apparatus such as a ventilator or an oxygen inhaler. The breathing apparatus 1000 is suitable for various applications in home use. The respiratory mask 100 is an oronasal mask that covers the nose and mouth of a user. In some possible embodiments, the respiratory mask 100 may also be just a nasal mask that covers the nose of the user.

Referring to fig. 2 in combination, fig. 2 shows a schematic diagram of a respiratory mask provided in an embodiment of the present application. The respiratory mask 100 comprises a mask body 10 and a positioning assembly 20, wherein the positioning assembly 20 is arranged on the mask body 10 and is fixed with the mask body 10.

The cover 10 is provided with a connection port 11 connected to the pipeline 200. In this embodiment, the connection port 11 is circular for adapting to the pipeline 200. The breathing mask 100 is provided with a matching part 30 which is relatively fixed with the pipeline 200 at the connecting port 11, and the matching part 30 is used for being matched and fixed with the positioning assembly 20. The housing 10 is rotatably assembled with the pipe 200. Because the cover 10 and the pipeline 200 rotate relatively, the position relationship between the matching part 30 and the positioning assembly 20 also changes, and the cover 10 and the pipeline 200 can be positioned at different angles.

Because the angles of the breathing mask 100 and the pipeline 200 can be adjusted in the breathing mask 100, the user can select the pipeline angle fixed at a weight which is more balanced relative to the face pressure, and discomfort caused by uneven stress on the face of the user is avoided.

Further, the respiratory mask 100 further includes a swivel body 40a and a swivel base 40b that swivel with each other. The rotating body 40a is fixed to the cover 10, and the rotating body 40a is sleeved on the rotating seat 40b and can rotate around the rotating seat 40b. The rotary seat 40b is fixed at the connection port 11, and the rotary seat 40 is fixed with the pipeline 200. Accordingly, the cover 10 rotates relative to the pipe 200 via the rotating body 40a and the rotating seat 40b. Since the engaging portion 30 is fixed to the rotating base 40b, the positioning assembly 20 is fixed to the cover 10.

The positioning assembly 20 comprises several positioning elements 21 arranged around the connection port 11. The housing 10 is operable to rotate relative to the conduit 200 such that either positioning element 21 is selectively securable to the mating portion 30. When the different positioning elements 21 are fixed to the mating portion 30, the angle between the pipe 200 and the housing 10 is different.

In the present embodiment, the matching portion 30 is provided with a magnetic attraction element 301, the positioning element 21 is provided with an electromagnetic element 211, and the respiratory mask 100 further includes a power source 50. The positioning elements 21 are electrically connected to the power source 50. The magnetic attraction element 301 may attract to a magnetic object, and the magnetic attraction element 301 is made of a metal material or a magnetic material. The electromagnetic element 211 is magnetized after being energized. The electromagnetic element 211 is made of an electromagnet or other materials which generate magnetism after being electrified.

In operation, the power supply 50 is selected to power only one of the positioning elements 21, the others not being powered. As can be appreciated, when the power supply 50 supplies power to the positioning element 21, the positioning element 21 has magnetism and is attracted to and fixed to the magnetic attraction element 301; when the power supply 50 is another positioning element 21, the other positioning element 21 is attracted and fixed to the magnetic attraction element 301. In this way, the cover 10 can be positioned at different angles, so that the relative angle between the cover 10 and the pipeline 200 is changed, and the angle between the cover 10 and the pipeline 200 can be adjusted.

The power supply 50 may also be implemented to include a power on button, and the user controls the power supply 50 to supply power to the positioning element by operating the power on button, which may be an electromagnetic module.

In particular, the mating portion 30 includes a pair of oppositely disposed magnetically attractable elements 301. Each positioning element 21 comprises a pair of oppositely disposed electromagnetic elements 211. Each pair of magnetic attraction elements 301 is disposed on the diameter of the rotary seat 40b, and each pair of electromagnetic elements 211 is disposed on the diameter of the rotary body 40 a. The positioning assembly 20 comprises four positioning elements 21, wherein the positioning elements 21 are arranged at equal intervals, namely 45 degrees between every two positioning elements.

It will be appreciated that in some possible embodiments, the number of the positioning elements 21 and the electromagnetic elements 211 may be other, and the number of the magnetic elements 301 in the corresponding mating portion 30 may be adapted.

In this embodiment, the respiratory mask 100 is configured to automatically control the power supply 50 to select the corresponding positioning element 21 and to supply power to the selected positioning element. That is, the respiratory mask 100 is also provided with corresponding control means for controlling the power supply 50.

Referring to fig. 2 in combination, fig. 2 shows a schematic diagram of a control device for controlling the power supply 50 of the respiratory mask 100. The control device 60 includes one or more control chips. Each control chip can implement a different control function. For ease of understanding, the present application describes and describes the control device 60 in terms of its various functions. Specifically, the control device 60 includes a logic control module 61, a first switch 62, and a circuit sampling module 64. The first switch 62, the second switch 63, and the circuit sampling module 64 are electrically connected to the logic control module 61. The logic control module 61 is electrically connected to the power source 50. Wherein the first switch 62 and the second switch 63 may be activated by a key and a button (not shown) provided on the cover 10.

The logic control module 64 controls to turn on or off the power supply 50 in response to the operation of the first switch 62. Specifically, when the user operates the first switch 62 to turn on the power supply 50, the logic control module 64 sequentially controls the power supply 50 to energize each positioning element 21, i.e., energize the pair of electromagnetic elements 211.

The circuit sampling module 64 is used to collect the electrical signal of each positioning element 21. That is, the circuit sampling module 64 is configured to collect electrical signals from each pair of electromagnetic elements 211. Wherein when the electrical signals of a pair of solenoid 211 change, the logic control module 64 selects the pair of solenoid 211 and controls the power source 50 to continuously energize the corresponding pair of solenoid 211. Since the electromagnetic element 211 attracts the attraction element 301, the current, the magnetic resistance, the magnetic flux, or the like of the magnetic element 211 changes. Accordingly, the electrical signals of each pair of electromagnetic elements 211 may be collected by the circuit sampling module 64 to determine which pair of electromagnetic elements 211 corresponds to an angle that is a comfort angle selected by a user, thereby continuously energizing the pair of electromagnetic elements 211 to secure the enclosure 10 at the comfort angle. When the electromagnetic element 211 attracts the attraction element 301, the current, magnetic resistance, magnetic flux, or the like of the electromagnetic element 211 changes. In particular implementations, the circuit sampling module 64 is configured to collect the current of each pair of electromagnetic elements 211 and to select a pair of electromagnetic elements 211 and to continuously energize the pair of electromagnetic elements 211 when the current of the pair of electromagnetic elements 211 becomes greater.

Further, the control device 60 further comprises a second switch 63, the second switch 63 being operable to control the control device to regulate the voltage or current provided by the power supply 50. In particular, a button for operating the second switch 63 is provided on the cover 10, and the user can cause the control device 60 to adjust the voltage or current supplied from the power supply 50 by operating the button. Specifically, the user can turn up or down the voltage or current supplied from the power supply 50 by operating the button, so that the degree of attraction between the electromagnetic element 211 and the magnetic attraction element 301 can be changed.

In order to understand the operation of the respiratory mask 100, a setup procedure of the respiratory mask 100 when worn will be provided below.

Referring to fig. 3, fig. 3 is a flowchart illustrating steps of a setup process for wearing the breathing mask 100 by a user. The setup process for wearing the breathing mask 100 by the user includes the following steps.

Step S301, the breathing mask 100 is worn.

In step S302, the respiratory mask 100 is adjusted to a comfort angle.

Step S303, the first switch 62 is triggered. The key of the first switch 62 is operated to trigger the first switch 62.

Step S304, supplying power to the electromagnetic element 211. After the first switch 62 is triggered, the power supply 50 is turned on to supply power to the electromagnetic element 211.

In step S305, the electromagnetic element 211 that needs to be locked is detected. The current of the electromagnetic elements 211 is detected, and when the current of the pair of electromagnetic elements 211 changes, the electromagnetic elements 211 that need to be locked are obtained.

Step S306 locks the angle of the breathing mask 100. The control power supply 50 maintains the solenoid 211 that is to be locked on, thereby locking the angle of the respiratory mask 100.

Step S307, the second switch 63 is triggered. The button of the second switch 63 is operated to trigger the second switch 63

Step S308 changes the suction force of the electromagnetic element 211. The second switch 63 controls the current or voltage supplied from the power supply 50 under the button manipulation, thereby increasing the suction force of the electromagnetic member 211 to a force that can lock the breathing mask 100.

Step S309, setting a locking force. When the force of the electromagnetic element 211 is enough to lock the breathing mask 100, the locking force is set.

The above operation steps can realize the angle locking and locking force of the breathing mask 100 when the breathing mask 100 is worn.

In the above embodiment, the breathing mask 100 is controlled to be positioned at different angles by means of electromagnetic method, and the suction force at the locking angle can be changed, so that the suction force can be adjusted according to the stress condition of the breathing mask 100, thus, the force of stable locking of the breathing mask 100 can be adjusted, and the breathing mask 100 can be stably locked.

It will be appreciated that the above embodiments allow the cover 10 to be positioned at different angles by electromagnetic means. In some possible embodiments, the engagement portion 30 and the positioning assembly 20 may be mechanically engaged to secure, and the respirator 100 may be locked at different angles to adjust the comfort angle.
