The embodiment of the utility model provides air disinfection equipment, which can be portable air disinfection equipment, for example, the air disinfection equipment is neck hanging equipment. As shown in fig. 1 to 6, the air sterilizing apparatus includes a housing 1, a negative ion generating assembly 2, and a discharging assembly 3. At least one side of the housing 1 is provided with a metal strip 11. The negative ion generating component 2 is arranged in the shell 1, the negative ion generating component 2 is used for emitting negative ions outwards, and the negative ion generating component 2 at least comprises a grounding module 21. The discharging component 3 is arranged in the shell 1, the discharging component 3 comprises a kiloohm resistor 31, the kiloohm resistor 31 is respectively connected with the metal strip 11 and the grounding module 21 in a conductive mode, and after the grounded conductor contacts the metal strip 11, negative ions released by the negative ion generating component 2 can flow in the direction where the conductor is located through an electric field formed between the conductor and the negative ion generating component 2.

Specifically, the upper surface and the lower surface of the housing 1 may be disposed to be open, and the housing 1 may further include an upper buckle plate 14 fastened to the upper opening and a lower buckle plate 15 fastened to the lower opening. The side walls of the housing, the upper pinch plate 14 and the lower pinch plate 15 may be made of non-metallic materials, such as glass, plastic, ceramic, rubber, etc. It will be appreciated that the various components of the housing may be formed from the same or different materials, as the utility model is not limited in this regard.

At least one side of the housing 1 is provided with a metal strip 11, at least part of the metal strip 11 being exposed to the environment, being accessible to a user or the like. The specific shape of the metal strip is not limited in the present utility model, and may be, for example, elliptical, square, waist-shaped, irregular, etc., and it is not required that it be strip-shaped, as long as it can provide a certain contact surface for a user, etc. Illustratively, as shown in fig. 2, 3 and 7, the two side walls of the housing 1 are respectively provided with a waist-shaped hole in which the metal strip 11 is fittingly embedded, the surface being exposed to the environment and being flush with the outer surface of the non-metallic housing 1. The metal strips are naturally accessible when the user holds the air disinfection apparatus. Also by way of example, the metal strip may also be provided on the lower pinch plate 15 of the housing or in other locations that are convenient for the user to reach.

Specifically, the casing 1 may be provided with a hanging portion, and the hanging rope may be threaded through the hanging portion, so as to facilitate the user wearing the casing through the hanging rope. Therefore, the air disinfection equipment can be more portable, and the requirements of disinfection at any time and any place can be met.

Specifically, the kilo-ohm resistor 31 is understood to be a resistor having a resistance of kilo-ohm or higher, and for example, the resistance of the kilo-ohm resistor 31 may be 500 kilo-ohm, 100 megaohm, or the like. Illustratively, the resistance of the kilo-ohm resistor 31 may be megaohm-level or higher, so that the current through the kilo-ohm resistor 31 does not exceed microampere level when the air disinfection device is in operation, thereby being capable of meeting the high-requirement product standard, such as the medical electrical device standard.

It should be understood that the kilo-ohm resistor 31 in the embodiment of the present utility model may refer to a single resistor, or may be an assembly formed by a plurality of resistors and other possible components, so long as the resistance value thereof can reach at least a kilo-ohm level or higher.

Specifically, the above-described electric conductor may be understood as a human body, other living body (e.g., pet, etc.), or an object that is grounded and capable of conducting electricity. Hereinafter, a conductive body will be described in detail as an example of a human body.

The air sterilizer can perform an open work without the human body contacting the metal strip 11. The carbon brush tip of the negative ion generating component generates high-pressure corona under the action of negative high pressure, and air is continuously ionized, so that a large number of positive and negative ion pairs are formed, positive ions move to the bottom of the carbon brush and are finally neutralized with the positive ions due to the action of the negative high pressure, and a large number of electrons are rapidly released into the air through the plurality of tips of the carbon brush. The electron lifetime is extremely short (nanosecond level), can not exist in the air for a long time, and the affinity to oxygen is far greater than N ₂ Affinity to other gases in the air, and CO in the air ₂ The content is far lower than O ₂ So that most of electrons generated by ionization are captured by oxygen to form negative oxygen ions. The negative oxygen ions are far away from the tip of the carbon brush under the rejection of the negative high-voltage electric field, so that negative ion wind is formed. The open structure takes the carbon brush as a negative electrode and takes the whole space (such as the ground, the table top and the like in the environment) where the air disinfection equipment is positioned as a positive electrode, so that a high-voltage electrostatic field is formed between the positive electrode and the negative electrode, and the whole space is filled with the electrostatic field. This can enhance the effect of diffusing negative oxygen ions into the surrounding space, in which case the diffusivity of the negative ions is good and the ion concentration is high.

As shown in fig. 2, in the case where a human body holds the air sterilizer, touches the metal strip 11, and the human body is in a grounded state, the air sterilizer can perform a closed type operation. And under the action of negative high pressure, the carbon brush tip of the negative ion generating component rapidly releases electrons into the air and forms negative oxygen ions. Because the hand of human body contacts with the metal strip, the metal strip 11 is grounded through the kiloohm resistor 31 and the grounding module 21, and at the moment, the human body is in high potential relative to a carbon brush (negative high voltage) of the negative ion generating component, a closed electrode is formed between the carbon brush and the human body, and a stronger electric field is formed, so that negative ions released by the negative ion generating component 2 can flow in the direction of the conductive body to form cold spray negative ion wind, the local negative oxygen ion concentration of the human body can be directionally improved, the local disinfection effect is improved, and the aim of increasing the disinfection effect is fulfilled. Meanwhile, because the cold spray negative ion wind is blown to the human body in a directional way, the capability of the human body for taking in negative oxygen ions can be improved, thereby enhancing cardiovascular and cerebrovascular functions and the like and improving the functions of the human body. Because the kiloohm resistor 31 exists, the field intensity between the carbon brush of the negative ion generating component and the human body is not too high, so that too much ozone can not be generated in a closed working mode, and the exceeding of ozone can be effectively avoided.

The air disinfection apparatus of the present utility model is capable of supporting both open and closed operating scenarios. Under the condition of closed type work, negative ions released by the negative ion generating component 2 can flow in the direction of the conductor, so that the concentration of the negative ions in the surrounding environment of the conductor is increased, the air purifying effect on the surrounding environment of the conductor is effectively improved, and the problem that in the prior art, the air purifier product can only gradually diffuse the negative ions into the air and cannot increase the concentration of local negative ions is solved.

In particular, a battery 9 may be further provided in the housing 1, and the battery 9 may be a lithium battery or other possible battery types, so as to freely move the air disinfection device after charging the battery, thereby increasing the flexibility of use of the air disinfection device.

In some embodiments, as shown in fig. 7 to 9, opposite sides of the housing 1 are provided with metal strips 11, respectively. It is possible for a user to first touch one side of the housing 1 or the other when he or she takes the air disinfection device. In this way, as long as the user picks up the device from both sides, no matter which side is touched first, the finger can naturally touch any one or more metal strips 11, and further silently release locally accumulated charges, without the user having to deliberately remember which specific position needs to be touched first or to perform according to specific operation steps, so that the user is more friendly while avoiding being electrified.

In particular, the two metal strips 11 may be connected in parallel and electrically connected to one kilo-ohm resistor 31, or may be electrically connected to different kilo-ohm resistors 31, respectively.

In some embodiments, as shown in fig. 7 to 9, the kilo-ohm resistors 31 are electrically connected to the metal strips 11 in a one-to-one correspondence, and the kilo-ohm resistors 31 are connected in parallel, so that when the electrical conductor contacts one of the two metal strips 11, the negative ions released by the negative ion generating component 2 can flow in the direction of the electrical conductor.

In some embodiments, as shown in fig. 7-9, the bleeder assembly 3 further comprises a bleeder circuit board 32, the kilo-ohm resistor 31 is provided on the bleeder circuit board 32, and the kilo-ohm resistor 31 is electrically conductively connected to the grounding module 21 through the bleeder circuit board 32.

Specifically, the above-described bleeder circuit board 32 may be constructed in a long strip shape with both ends in the longitudinal direction thereof abutting against the metal strips 11 located on both sides of the casing 1, respectively.

In some embodiments, as shown in fig. 7 to 9, the tapping assembly 3 further comprises a conductive spring 33 and a conductive connection 34 connected, the kiloohm-resistor 31 being electrically conductively connected to the metal bar 11 by the conductive spring 33 and the conductive connection 34.

Specifically, the axial direction of the conductive spring 33 may be parallel to the length direction of the bleeder circuit board 32, and one end of the conductive spring 33 may be connected to the inner wall of the metal bar 11 by welding, abutment, or the like, as possible.

Specifically, the conductive connector 34 may be removably attached to the bleeder circuit board 32.

In some embodiments, as shown in fig. 9, the bleeder circuit board 32 may be electrically conductively connected to the ground module 21 by a ground spring 35.

In some embodiments, as shown in fig. 7 to 9, the bleeder circuit board 32 is provided with a mounting hole, and the conductive connection member 34 is inserted through the mounting hole, so that the bleeder circuit board 32 is detachably connected to the housing 1. In this way, the conductive connector 34 not only has a conductive function, but also has a fixing function, so that the bleeder circuit board 32 is stably provided on the casing 1. The structure is compact, so that the space below the bleeder circuit board 32 can be better used for accommodating structural components such as the negative ion generating component 2, and the structure layout is more reasonable.

Specifically, as shown in fig. 9, the metal strips 11, the conductive springs 33, the conductive connectors 34, and the kilo-ohm resistors 31 are arranged in a one-to-one correspondence.

In some embodiments, as shown in fig. 8, the casing 1 has a first plate surface and a second plate surface that are disposed opposite to each other, the bleeder circuit board 32 is disposed near the first plate surface of the casing 1, and a first accommodating cavity 4 is formed between the second plate surface and the bleeder circuit board 32, and the first accommodating cavity 4 is used for accommodating at least the negative ion generating component 2. The structural design layout is reasonable and compact.

Specifically, the battery 9 may be disposed in the first accommodating chamber 4.

The anion generating assembly 2 in the embodiment of the present utility model is mainly used for generating and releasing anions, and the anion generating assembly may use an existing ion generator, or may use other possible structures.

In some embodiments, as shown in fig. 1 to 6, the negative ion generating assembly 2 further includes an ion emitting electrode assembly 22 and a high voltage generating circuit board 23 electrically connected to the ion emitting electrode assembly 22, the ion emitting electrode assembly 22 is used for emitting negative ions outwards, the grounding module 21 is connected to the high voltage generating circuit board 23, and the high voltage generating circuit board 23 is used for forming a direct current negative high voltage and conducting the direct current negative high voltage to the ion emitting electrode assembly 22 to ionize air to generate negative ions.

In some alternative embodiments, the high voltage generating circuit board 23 boosts the low voltage and then rectifies the boosted voltage to obtain the required negative high voltage. The negative ion generating assembly 2 may also include a glue-filled housing. Since the high-voltage generating circuit board 23 works to generate high-frequency voltage, the devices on the high-voltage generating circuit board 23 are easily damaged, and therefore, the high-voltage generating circuit board 23 is fixed in the glue-pouring shell by epoxy resin glue, and the function of protecting the devices on the circuit board can be achieved. In addition, the high voltage generating circuit board 23 may be soldered with wires, which should be passed through the round holes on the side wall of the glue-pouring shell before glue pouring, so that the high voltage generating circuit board 23 can be electrically connected with other electrical devices. The conducting wire can be a good conductor of electricity such as an iron wire or a copper wire.

In some alternative embodiments, the ion-emitting electrode assembly 22 may include a plurality of equally spaced carbon brushes and an ion-emitting electrode circuit board, and the ion-emitting electrode circuit board may be provided with bonding pads, the carbon brushes may be in communication with the bonding pads, and the wires on the high voltage generation circuit board 23 may be soldered to the bonding pads. Specifically, the carbon brush serves as a negative electrode, and surrounding objects, the earth, etc. serve as a positive electrode, so that a high-voltage electrostatic field is formed between the positive electrode and the negative electrode. The high voltage generating circuit board 23 makes the tip of the carbon brush have direct current negative high voltage, thereby generating high voltage corona, and the air is continuously ionized to form a large number of positive and negative ion pairs. Most of positive and negative ion pairs formed by ionization are captured by oxygen to form negative ions, and the negative ions move away from the tip of the carbon brush under the repulsion of a negative high-voltage electric field. Thus, when the user holds the air disinfection device, the negative ions released by the negative ion generating component 2 can flow in the direction of the electric conductor under the action of the discharging component 3, so that negative ion wind sprayed to the electric conductor is formed; when the user does not hold the air disinfection device, the negative ions released by the negative ion generating component 2 can diffuse to the surrounding space, so that the space where the air disinfection device is positioned is filled with an electrostatic field, and the negative ion concentration of the surrounding space is rapidly improved.

In some embodiments, as shown in fig. 3 and 5, the other side of the case 1 is provided with a negative ion release groove 12, and the aforementioned ion emitting electrode circuit board, carbon brush, etc. may be provided in the negative ion release groove 12. The negative ions emitted from the negative ion generating assembly 2 are discharged from the negative ion discharge groove 12.

Since the negative ion generating component 2 works to generate negative high voltage, the air sterilizing device can locally accumulate charges under the condition of open work, thus generating two problems: when a human body approaches the air disinfection equipment, an electric phenomenon can occasionally occur (the air disinfection equipment discharges static electricity to the human body when the human body approaches); when the air disinfection device is charged by a charger, the plug of the charger is close to the device and a discharge phenomenon is generated.

When the air disinfection device in the embodiment of the utility model is adopted, when a user holds the device or prepares to charge, the user can hold the device by pinching the two sides of the air disinfection device, which are provided with the metal strips 11, after the hands contact the metal strips 11 on the two sides, the charge on the air disinfection device can be conducted to the human body through the kiloohm resistor 31 and the metal strips 11, and the human body releases the charge through the earth, and the aim of protecting the safety of the human body can be achieved because the kiloohm resistor 31 is arranged, so that the charge flowing through the human body is very weak and does not generate a strong discharge phenomenon. For example, the carbon brush may generate 10000 volts, the kilo-ohm resistor 31 may be 100 megaohms, and the current generated is 10000/(100×10) ⁶ ) Since the current flowing through the human body is extremely weak, the strong discharge phenomenon is effectively avoided by providing the kilo-ohm resistor 31.

In some scenarios, the user may not contact the metal strip 11 while taking the air sanitizer, but rather contact other locations of the housing 1, such as the upper pinch plate 14 and the lower pinch plate 15 as shown in fig. 1 and 3. In these cases, the user may still be powered if the device locally has accumulated charge at this time.

In view of this problem, the present utility model proposes that the air sterilizer further comprises a control module (not shown in the drawings) and an object detection sensor 5 (as shown in fig. 1 to 3) provided on the housing 1, the emission surface of the object detection sensor 5 being disposed toward the negative ion discharge slot 12 for emitting a detection area formed to cover the negative ion discharge slot 12 and generating detection information when there is an obstacle in the detection area, the control module being electrically connected to the ion emission electrode assembly 22 and the object detection sensor 5, respectively, and the control module being for receiving the detection information fed back by the object detection sensor 5 and transmitting a closing instruction to the ion emission electrode assembly 22. In one aspect, the negative high pressure generated at the ion emitting electrode assembly 22 may be prevented from injuring a human body or an object when a user is about to inadvertently touch the carbon brush. On the other hand, even if the user does not contact the metal strip 11 first, but picks up the air sterilizer by contacting other positions of the case 1, for example, the human hand can pick up the air sterilizer by pinching the front position of the object detection sensor 5, with the above-described implementation, the object detection sensor 5 detects that there is an object shielding, and the ion emitting electrode assembly 22 will be turned off to stop ion emission, so that a discharge phenomenon is not generated, that is, the user can be prevented from being electrified to some extent. So, through setting up object detection sensor 5 and the cooperation of release subassembly 3, can further solve above-mentioned two technical problem, promote safety in utilization, promote user's use experience.

In some embodiments, the air disinfection apparatus further comprises a movable shutter 6, the movable shutter 6 being slidably arranged on the housing 1 for shielding or exposing the anion releasing groove 12. Specifically, in conjunction with fig. 3 to 6, the negative ion release groove 12 shown in fig. 3 and 4 is in an exposed state, and the negative ion release groove 12 shown in fig. 5 and 6 is in a shielded state.

In some embodiments, as shown in fig. 4 and 6, the air disinfection apparatus further comprises a switch module 7, the flapper 6 comprising a trigger portion 61 located within the housing 1, the trigger portion 61 for triggering the switch module 7 when the flapper 6 exposes the anion releasing groove 12. The above-mentioned switch module 7 is configured as a module capable of controlling the air sterilizer to be in an on state or an off state.

Thus, when the anion releasing groove 12 is exposed, the switch module 7 can be triggered by the triggering part 61 without manual starting of a user, and the air disinfection device is in a starting state.

In some embodiments, as shown in fig. 1 to 6, 11 and 12, the movable baffle 6 includes a plate body 62 and a striking part 63, the plate body 62 is used for shielding or exposing the negative ion releasing slot 12, a chute 13 is provided on one side of the housing 1, the striking part 63 is slidably provided in the chute 13, a positioning member 16 provided near the striking part 63 is provided in the housing 1, at least two grooves 64 are provided along the sliding direction of the striking part 63, and the positioning member 16 is used for being clamped into one of the at least two grooves 64 when the striking part 63 slides so as to limit the displacement of the striking part 63.

As shown in fig. 3, 4 and 11, when the toggle portion 63 is forced to slide downward, the plate 62 moves downward along with the toggle portion 63 to expose the carbon brush, the trigger portion 61 triggers the switch module 7 to start the air disinfection apparatus, and at this time, the positioning member 16 is snapped into the groove 64 disposed above the two grooves 64.
