[0010] In one embodiment, the dust collection module includes a high-pressure dust collection transformer and a dust collection mesh assembly. The high-pressure dust collection transformer has a first output port and a second output port, and the second output port is connected to the dust collection mesh assembly.

[0011] In one embodiment, the dust collection mesh assembly includes a dust collection frame and an electrostatic dust collection mesh disposed on the dust collection frame. The dust collection frame is connected to the edge of the return air inlet, and the electrostatic dust collection mesh covers the return air inlet.

[0012] In one embodiment, a clearance receiving groove is provided on one side of the dust collection frame, and the connection between the high-pressure dust collection pack and the dust collection mesh assembly is located in the clearance receiving groove.

[0013] In one embodiment, the high-pressure dust collection unit and the dust collection screen assembly are detachably connected via an adapter assembly;

[0014] And / or, a micro switch is provided between the high-pressure dust collection unit and the dust collection mesh assembly to control the on / off connection between the high-pressure dust collection unit and the dust collection mesh assembly;

[0015] And / or, the dust collection high-pressure pack is fixedly installed on the edge of the return air inlet and is located close to the electrical control module.

[0016] In one embodiment, the input port of the dust collection module is connected to the third output port of the negative ion generating module, and the input port of the negative ion generating module is connected to the electronic control module.

[0017] In one embodiment, the dust collection module includes an adapter assembly and a dust collection screen assembly. The adapter assembly has the input port and a second output port, the second output port being electrically connected to the dust collection screen assembly.

[0018] In one embodiment, the housing has a reserved dust collection mounting position for selectively mounting the dust collection module, and the electronic control module is electrically connected to the negative ion generating module.

[0019] In one embodiment, the dust collection module is detachably connected to the dust collection mounting position.

[0020] In one embodiment, one end of the negative ion generating module is connected to the wall of the air outlet, and the other end is suspended in the air.

[0021] In one embodiment, the negative ion generating module includes a negative ion high-voltage transformer and a negative ion generating component. The negative ion high-voltage transformer is connected to the hole wall of the air outlet and is electrically connected to the dust collection module.

[0022] The negative ion high-voltage pack has a negative ion emission port, and the negative ion generating component is electrically connected to the negative ion emission port.

[0023] In one embodiment, the distance between the negative ion generating component and the hole wall of the air outlet is greater than or equal to 30 mm.

[0024] In one embodiment, the negative ion generating module further includes a box body and a first box cover, the box body and the first box cover being connected to form a receiving cavity for receiving the negative ion high-voltage pack, and the box body being fixedly connected to the shell.

[0025] In one embodiment, the box body and the negative ion high-pressure pack are integrally injection molded;

[0026] And / or, the negative ion generating module further includes a second cover, which is disposed on the side of the box body away from the first cover.

The ion carbon brush passes through a hole in the box body and is disposed close to the electrode.

[0027] In this invention, a negative ion generating module is installed at the air outlet of the air conditioner. This ensures that the high-energy electrons released by the negative ion generating module are directly carried out of the air conditioner by the wind, improving the purification and sterilization effect and reducing the risk of electrostatic breakdown of the motor, circuit board, etc., caused by the diffusion of high-energy electrons into the casing, thus improving the safety and service life of the air conditioner. During the return air process, high-energy electrons interact with air molecules to form negative ions, causing fine dust particles and bacteria to become electrostatically charged. Some of the fine dust particles are deposited on the ground, while others are carried back to the air return vent of the air conditioner. Since a dust collection module is separately installed at the return air vent from the negative ion generating module and is powered by the electronic control module, the charged fine dust particles are adsorbed and killed when they enter the casing through the dust collection module, thereby improving the purification and sterilization effects.

[0028] The system connects the negative ion generator module or the dust collection module via an electrical control module, providing power to either module. Furthermore, because the negative ion generator module and the dust collection module are electrically connected, the electrical control module can also supply power to either module. This allows the single interface of the electrical control module to provide bidirectional power to both the negative ion generator module and the dust collection module, enabling them to operate simultaneously and increasing the air conditioner's purification and sterilization capabilities. Simultaneously, this simplifies the structure and circuitry of the electrical control module, reducing its size and cost, thus allowing for a more efficient allocation of internal space and more organized wiring within the air conditioner.

[0046] In the existing technology, for multiple functional modules that require power supply, air conditioners usually have multiple circuit boards or multiple ports on one circuit board to provide power to each functional module. However, this can easily occupy the internal space of the air conditioner, and the wiring is messy and disorganized. It also makes the overall structure of the circuit board more complicated and increases its size.

[0047] To address the aforementioned problems, this utility model proposes an air conditioner.

[0048] Please see Figures 1 to 7 In one embodiment of this utility model, the air conditioner includes a housing 10, a negative ion generating module 20, a dust collection module 30, and an electronic control module. The housing 10 is provided with an air outlet 11 and a return air outlet 12. The negative ion generating module 20 is located at the air outlet 11. The dust collection module 30 is located at the return air outlet 12. The dust collection module 30 and the negative ion generating module 20 are electrically connected. The electronic control module is electrically connected to either the dust collection module 30 or the negative ion generating module 20. Thus, the single interface of the electronic control module can provide bidirectional power supply to both the negative ion generating module 20 and the dust collection module 30. This simplifies the internal wiring of the air conditioner while meeting the power requirements of the negative ion generating module 20 and the dust collection module 30. It also simplifies the structure of the electronic control module and can improve the purification and sterilization efficiency of the air conditioner to a certain extent.

[0049] In the technical solution of this utility model, a negative ion generating module 20 is set at the air outlet 11 of the air conditioner. This ensures that the high-energy electrons released by the negative ion generating module 20 are directly carried out of the air conditioner by the wind, improving the purification and sterilization effect and reducing the risk of electrostatic breakdown of the motor, circuit board 41, etc. caused by the diffusion of high-energy electrons into the housing 10, thereby improving the safety and service life of the air conditioner. During the return air process, high-energy electrons interact with air molecules to form negative ions, which cause fine dust particles and bacteria to become electrostatically charged. Some of the fine dust particles are deposited on the ground, while some are carried back to the air return vent 12 of the air conditioner. Since a dust collection module 30 is set separately from the negative ion generating module 20 at the air return vent 12 and is powered by the electronic control module, the charged fine dust particles are adsorbed and killed when they enter the housing 10 through the dust collection module 30, thereby improving the purification and sterilization effect.

[0050] The system connects the negative ion generator module 20 or the dust collection module 30 to the electrical control module, providing power to either module. Furthermore, because the negative ion generator module 20 and the dust collection module 30 are electrically connected, the electrical control module can also supply power to either module. This allows the single interface of the electrical control module to provide bidirectional power to both the negative ion generator module 20 and the dust collection module 30. Consequently, the negative ion generator module 20 and the dust collection module 30 can operate simultaneously, increasing the air conditioner's purification and sterilization capabilities. Simultaneously, this simplifies the structure and circuitry of the electrical control module, reduces its size and cost, and allows for a more efficient allocation of the air conditioner's internal space, while also standardizing the internal wiring.

[0051] It should be noted that when a large number of high-energy electrons diffuse into the housing 10, the generated negative ions are adsorbed and deposited on the surface of the housing 10 (sheet metal part), thus reducing the number of negative ions. By placing the negative ion generating module 20 at the air outlet 11 and as close as possible to the end of the air outlet 11 facing the external environment, the released high-energy electrons can be directly discharged outside the air conditioner with the wind to the maximum extent, which can increase the diffusion path and range of the generated negative ions and improve the purification and sterilization effects. The dust collection module 30 at the return air outlet 12 adsorbs dust, bacteria and other particles smaller than PM2.5, ensuring that the air entering the housing 10 is clean air and reducing the impact of deposition on the air conditioner. This reduces the risk of damage to the motor, circuit board 41 and other components due to the continuous deposition of charges on their surfaces, which may reach the level of electrostatic breakdown, thereby further improving the safety and service life of the air conditioner.

[0052] The electronic control module includes an electronic control box and a circuit board 41 disposed inside the electronic control box. The power output port of the circuit board 41 is connected to a power output line 51, which is used to connect to the input port of the dust collection module 30 or the negative ion generation module 20. The electronic control module is fixed to the back of the hole wall of the return air vent 12 or the air outlet 11 and is hidden and housed in the housing 10, so that the circuit board 41 can be connected to the dust collection module 30 or the negative ion generation module 20 through the power output line 51 to achieve power supply.

[0053] Please see Figure 2 In one embodiment of this utility model, the input port of the dust collection module 30 is connected to the electronic control module, and the first output port of the dust collection module 30 is connected to the input port of the negative ion generating module 20. It can be understood that the input port of the dust collection module 30 is connected to the circuit board 41 through the power output line 51, and the first output port of the dust collection module 30 is connected to the input port of the negative ion generating module 20 through the negative ion connection line 52, so as to realize the transmission and diversion of electrical energy. Thus, part of the electrical energy entering the dust collection module 30 enables the dust collection module 30 to work, and the other part is transmitted to the negative ion generating module 20 to work. In this way, the purification and sterilization capabilities of the air conditioner are improved by the simultaneous operation of the dust collection module 30 and the negative ion generating module 20.

[0054] Please see Figure 3 In an embodiment of this utility model, the dust collection module 30 includes a high-pressure dust collection transformer 31 and a dust collection mesh assembly 32. The high-pressure dust collection transformer 31 has a first output port and a second output port. The second output port is connected to the dust collection mesh assembly 32. Furthermore, the first output port is connected to a negative ion connection line 52 to transmit electrical energy to the negative ion generating module 20. In this process, the electrical energy transmitted to the negative ion generating module 20 can be electrical energy that has not been processed by the high-pressure dust collection transformer 31. That is, the dust collection module 30 only acts as a transmission channel to transmit electrical energy, while the negative ion generating module 20 is correspondingly equipped with a high-pressure negative ion transformer 21 for high-pressure processing. Of course, the electrical energy transmitted to the negative ion generating module 20 can also be electrical energy that has been processed by the high-pressure dust collection transformer 31. The processed electrical energy; the second output port is connected to the dust collection mesh assembly 32 via a dust collection connection cable or adapter assembly 33, so as to transmit the high voltage electricity processed by the dust collection high voltage pack 31 to the dust collection mesh assembly 32, ensuring that the dust collection mesh assembly 32 is reliably charged, so as to complete the adsorption and killing of fine dust, bacteria, etc. By setting the dust collection high voltage pack 31, the electric field design unique to the dust collection module 30 can be realized, that is, the output electric field can be configured as a constant voltage field to achieve constant dust collection. Similarly, when the negative ion generating module 20 is equipped with a negative ion high voltage pack 21, the electric field design unique to the negative ion generating module 20 can be realized, that is, the output electric field can be configured as an alternating electric field to fully ionize the air, thereby maximizing the sterilization and purification effects.

[0055] Specifically, in the embodiments of this utility model, the dust collection mesh assembly 32 includes a dust collection frame 321 and an electrostatic dust collection mesh 322 disposed on the dust collection frame 321. The dust collection frame 321 is connected to the edge of the return air vent 12, and the electrostatic dust collection mesh 322 covers the return air vent 12. The connection method between the dust collection frame 321 and the edge of the return air vent 12 includes, but is not limited to, snap-fit ​​connection and screw connection. The dust collection frame 321 and the electrostatic dust collection mesh 322 are integral parts, which can be fixed into a whole by integral molding, welding or other methods, thereby improving the assembly efficiency of the dust collection mesh assembly 32. After being energized, the electrostatic dust collection mesh 322 can generate a strong electric field that adsorbs fine dust, bacteria and the like, ensuring that the electrostatic dust collection mesh 322 has purification and sterilization capabilities. However, in other embodiments, by improving the structure and materials of the dust collection mesh assembly 32, it can also have purification and sterilization capabilities when not energized.

[0056] Optionally, in an embodiment of this utility model, a clearance receiving groove 323 is provided on one side of the dust collection frame 321, and the connection between the dust collection high-pressure pack 31 and the dust collection mesh assembly 32 is located in the clearance receiving groove 323. This can improve the compactness of the dust collection high-pressure pack 31 and the dust collection mesh assembly 32, and facilitate the improvement of the reliability of the electrical connection. Taking the dust collection high-pressure pack 31 and the dust collection mesh assembly 32 as an example where they are detachably connected by an adapter assembly 33, the adapter assembly 33 is located at the connection between the dust collection high-pressure pack 31 and the dust collection mesh assembly 32. Specifically, the adapter assembly 33 is located above the dust collection high-pressure pack 31, and the adapter assembly 33 includes an adapter bottom shell 333 and an adapter cover 334 that cover each other, a mating plug 331 and a mating insert 332 that plug in and fit together. The adapter bottom shell 333 and the adapter cover 334 can... When the connection is made, the adapter bottom shell 333 can be integrally injection molded with the dust collection high-pressure pack 31, or fixed into a whole by other connection methods, which is conducive to the rapid assembly of the dust collection high-pressure pack 31 and the adapter assembly 33 on the housing 10; and one of the mating plug 331 and mating tab 332 is housed between the adapter bottom shell 333 and the adapter cover 334 and is electrically connected to the dust collection high-pressure pack 31, while the other is fixed in the clearance receiving groove 323 and is electrically connected to the electrostatic dust collection net 322. This facilitates the quick separation of the dust collection frame 321, which is connected to the electrostatic dust collection net 322, from the housing 10, and also improves the efficiency and convenience of the electrical connection between the dust collection high-pressure pack 31 and the dust collection net assembly 32; when the dust collection high-pressure pack 31 and the dust collection net assembly 32 are electrically connected by dust collection connecting wires, some of the dust collection connecting wires can be hidden in the clearance receiving groove 323.

[0057] Furthermore, in an embodiment of this utility model, a micro switch is provided between the high-pressure dust collection unit 31 and the dust collection mesh assembly 32 to control the on / off connection between the high-pressure dust collection unit 31 and the dust collection mesh assembly 32. It can be understood that when the high-pressure dust collection unit 31 is connected to the dust collection mesh assembly 32 via an adapter assembly 33, the micro switch can be integrated into the adapter assembly 33. Then, by controlling the electrical connection between the mating plug 331 or mating tab 332 located in the bottom shell 333 of the adapter and the high-pressure dust collection unit 31, that is, when the dust collection mesh assembly 32 is assembled in place, the mating plug 331 and mating tab 332 are plugged into each other, and the dust collection frame 321 presses against the adapter assembly 33, the micro switch switches to a normally closed state, ensuring reliable connection between the mating plug 331 or mating tab 332 and the high-pressure dust collection unit 31, thus achieving safe operation of the electrostatic dust collection mesh 322. This effectively reduces the possibility of poor contact caused by improper installation of the electrostatic dust collection mesh 322.

[0058] Please see Figure 2 In this embodiment of the present invention, the high-pressure dust collection pack 31 is fixedly installed on the edge of the return air vent 12 and is positioned close to the electrical control module. Thus, by utilizing the dust collection mounting position 13 on the edge of the return air vent 12, before connecting the dust collection mesh assembly 32 to the edge of the return air vent 12, the high-pressure dust collection pack 31 is fixed at the corresponding position on the dust collection mounting position 13, i.e., close to the electrical control module. This allows the high-pressure dust collection pack 31 to connect to the circuit board 41 in the electrical control module and also ensures the connection between the high-pressure dust collection pack 31 and the electrostatic dust collection mesh 322 within the dust collection mesh assembly 32, improving the convenience of electrical connection. Simultaneously, it facilitates the integrated design of the high-pressure dust collection pack 31 and the adapter assembly 33, and by embedding the adapter assembly 33 into the avoidance receiving groove 323, the compactness between the high-pressure dust collection pack 31 and the dust collection mesh assembly 32 is improved.

[0059] Optionally, in another embodiment of this utility model, the input port of the dust collection module 30 is connected to the third output port of the negative ion generating module 20, and the input port of the negative ion generating module 20 is connected to the electronic control module. It can be understood that the input port of the negative ion generating module 20 is connected to the circuit board 41 through the power output line 51, and the third output port of the negative ion generating module 20 is connected to the input port of the dust collection module 30 through the dust collection connection line, so as to realize the transmission and diversion of electrical energy. Then, part of the electrical energy entering the negative ion generating module 20 makes the negative ion generating module 20 work, and the other part is transmitted to the dust collection module 30, making the dust collection module 30 work. Thus, the air conditioner's purification and sterilization capabilities are improved by the simultaneous operation of the dust collection module 30 and the negative ion generating module 20.

[0060] Specifically, in an embodiment of this utility model, the dust collection module 30 includes an adapter assembly 33 and a dust collection mesh assembly 32. The adapter assembly 33 has an input port and a second output port. The second output port is electrically connected to the dust collection mesh assembly 32. Furthermore, the input port of the adapter assembly 33 is connected to a dust collection connection line so that the electrical energy processed by the negative ion generating module 20 is transmitted to the adapter assembly 33 and then to the second output port. The second output port is directly connected to the dust collection mesh assembly 32 so that the electrical energy is directly transmitted to the dust collection mesh assembly 32, ensuring that the dust collection mesh assembly 32 is reliably energized so as to complete the adsorption and killing of fine dust, bacteria, etc. That is, while ensuring the normal operation of the dust collection module 30 and the negative ion generating module 20, the setting of the dust collection high-voltage transformer 31 is reduced, which can reduce the cost to a certain extent.

[0061] The dust collection mesh assembly 32 includes a dust collection frame 321 and an electrostatic dust collection mesh 322 disposed on the dust collection frame 321. The dust collection frame 321 is connected to the edge of the return air vent 12, and the electrostatic dust collection mesh 322 covers the return air vent 12. The adapter assembly 33 includes at least a plug-in connector 331 and a connector tab 332, and one of the plug-in connector 331 and the connector tab 332 is electrically connected to the negative ion generating module 20. The other is fixed in the clearance receiving groove 323 of the dust collection frame 321 and is electrically connected to the electrostatic dust collection mesh 322. In addition, the edge of the return air vent 12 is provided with a corresponding mounting position for the adapter assembly 33 to facilitate quick plug-in connection between the plug-in connector 331 and the connector tab 332.

[0062] Please see Figure 4 In this embodiment of the present invention, a dust collection mounting position 13 is reserved on the housing 10. The dust collection mounting position 13 is used to selectively install the dust collection module 30, and the electrical control module is electrically connected to the negative ion generating module 20. It can be understood that the dust collection module 30 is an optional accessory. When the air conditioner only includes the negative ion generating module 20, the input port of the negative ion generating module 20 is connected to the circuit board 41 to realize the power supply to the negative ion generating module 20. That is, the negative ion generating module 20 realizes the basic function of the air conditioner, which can meet the purification and sterilization effects required by some users. Since the dust collection mounting position 13 is reserved on the housing 10, when the user needs better purification and sterilization effects, the dust collection module 30 can be directly installed on the dust collection mounting position 13 and the corresponding wiring can be completed. This allows the air conditioner to have both the dust collection module 30 and the negative ion generating module 20. When the dust collection module 30 and the negative ion generating module 20 work simultaneously, the purification and sterilization capabilities of the air conditioner are greatly enhanced.

[0063] The dust collection module 30 is detachably connected to the dust collection mounting position 13. It can be connected by snap-fit ​​or screws, which allows for flexible assembly and disassembly of the dust collection module 30 to obtain air conditioners of different specifications to meet different user needs. It also makes it convenient for users to disassemble and clean the dust collection mesh assembly 32.

[0064] Combined with reference Figure 1 and Figure 7 In an embodiment of this utility model, one end of the negative ion generating module 20 is connected to the hole wall of the air outlet 11, and the other end is suspended. This facilitates the suspension of the ion emission area of ​​the negative ion generating module 20, increases the number of negative ions directly diffused from the air outlet 11, thereby increasing the diffusion path and range of the formed negative ions, and improving the purification and sterilization effects.

[0065] Please refer to Figures 5 to 6 In an embodiment of this utility model, the negative ion generating module 20 includes a negative ion high-voltage pack 21 and a negative ion generating component 22. The negative ion high-voltage pack 21 is connected to the hole wall of the air outlet 11 and is electrically connected to the dust collection module 30. The negative ion high-voltage pack 21 has a negative ion emission port, and the negative ion generating component 22 is electrically connected to the negative ion emission port.

[0066] Understandably, considering the setup of the dust collection module 30, which includes a high-voltage dust collection transformer 31 and a dust collection mesh assembly 32, the input port of the dust collection module 30 is connected to the circuit board 41, the first output port of the high-voltage dust collection transformer 31 is connected to the input port of the negative ion generating module 20, and the channel from the input port to the first output port of the high-voltage dust collection transformer 31 serves only as a transmission channel for transmitting electrical energy. The input port of the negative ion generating module 20 is the power input port of the high-voltage negative ion transformer 21, the negative ion emission port of the high-voltage negative ion transformer 21 is connected to the negative ion generating assembly 22, and the second output port of the high-voltage dust collection transformer 31 is connected to... The dust collection mesh component 32 allows for targeted implementation of different electric field waveforms for the electrostatic dust collection mesh 322 and the negative ion generating component 22. Furthermore, by setting the high-voltage dust collection transformer 31, a unique electric field design for the dust collection module 30 is achieved, configuring the output electric field as a constant voltage field to achieve constant dust collection. Similarly, by setting the high-voltage negative ion generator 21, a unique electric field design for the negative ion generating module 20 is achieved, configuring the output electric field as an alternating electric field to fully ionize the air. Thus, by matching the power supply and electric field of each module, the sterilization and purification effects are maximized.

[0067] Based on this, the performance indicators of the air conditioner under the power condition of 3500W were tested and the following results were obtained: a high purification effect with a PCADR (purification efficiency) of 280m3 / h, a high sterilization effect with a sterilization rate of 99.12% within 2 hours, and the effective utilization rate of high-energy electrons and hydroxyl radicals generated by the negative ion generation module 20 tends to be 100%, ensuring that the sterilization and purification effects are maximized.

[0068] With the dust collection module 30 including the adapter assembly 33 and the dust collection mesh assembly 32, the input port of the negative ion generating module 20 is connected to the circuit board 41, the third output port of the negative ion high-voltage transformer 21 is connected to the input port of the adapter assembly 33 through the dust collection connection line, the negative ion emission port of the negative ion high-voltage transformer 21 is connected to the negative ion generating component 22, and the second output port of the adapter assembly 33 is connected to the dust collection mesh assembly 32. In this way, the negative ion generating component 22 works and releases high-energy electrons and other ionized air. At the same time, the dust collection module 30 uses the electrical energy transmitted from the negative ion high-voltage transformer 21 of the negative ion generating module 20 to work, thereby achieving dust collection and sterilization. This can ensure the purification and sterilization effects to a certain extent, while reducing the cost by eliminating the dust collection high-voltage transformer 31.

[0069] Since the dust collection module 30 is an optional accessory, the air conditioner can be equipped with only the negative ion generating module 20. In this case, the input port of the negative ion generating module 20 is directly connected to the circuit board 41, and the negative ion emission port is connected to the negative ion generating component 22. Based on this, the performance indicators of the air conditioner under the power condition of 3500W can be tested to obtain the following results: a purification effect of PCADR (purification efficiency) of 30m3 / h and a sterilization effect of at least 97% within 2 hours. This is suitable for users with low requirements for purification and sterilization, and greatly reduces costs.

[0070] Optionally, in an embodiment of this utility model, the distance between the negative ion generating component 22 and the hole wall of the air outlet 11 is greater than or equal to 30mm. When the distance between the negative ion generating component 22 and each hole wall is too small, i.e., less than 30mm, the generated negative ions are easily adsorbed and deposited on the surface by sheet metal parts such as the housing 10, resulting in a significant reduction in the number of ions finally blown out of the air outlet 11, thus reducing the utilization rate of negative ions. Therefore, the distance between the negative ion generating component 22 and each hole wall is set to be greater than or equal to 30mm, and the distance between the air outlet 11 and the hole wall is set to be greater than or equal to 30mm. The coverage depth of each hole wall of 1 on the negative ion generating component 22 is as shallow as possible to ensure that the negative ion generating component 22 is placed in the air and close to the outside of the air conditioner. When working, the high-energy electrons and hydroxyl radicals output by AC discharge can be directly discharged to the outside of the air conditioner with the wind, increasing the diffusion path and range of the generated negative ions. This ensures that the high-energy electrons and hydroxyl radicals are sprayed into the air with the wind to play a bactericidal role, and the fine dust particles may be deposited on the ground, or charged and returned to the return air vent 12 by the wind for adsorption and elimination by the dust collection module 30.

[0071] Please see Figure 6 In an embodiment of this utility model, the negative ion generating module 20 further includes a box body 23 and a first box cover 24. The box body 23 and the first box cover 24 are connected to form a cavity for receiving the negative ion high-voltage pack 21. The box body 23 is fixedly connected to the shell 10, which can reliably protect the negative ion high-voltage pack 21 and improve the assembly efficiency of the negative ion generating module 20 and the shell 10.

[0072] The connection methods between the box body 23 and the first box cover 24 include, but are not limited to, screw connection and snap-fit ​​connection; the connection methods between the box body 23 and the shell 10, i.e., the hole wall of the return air vent 12, include, but are not limited to, screw connection, snap-fit ​​connection and plug-in connection.

[0073] Specifically, in the embodiments of this utility model, the box body 23 and the negative ion high-voltage pack 21 are integrally injection molded; in this way, the connection stability between the box body 23 and the negative ion high-voltage pack 21 can be improved, the possibility of the negative ion high-voltage pack 21 shaking inside the box body 23 can be reduced, and the assembly process can be simplified, thereby improving the production efficiency and assembly difficulty of the negative ion generating module 20.

[0074] Specifically, in an embodiment of this utility model, the negative ion generating module 20 further includes a second cover 25, which is disposed on the side of the box body 23 away from the first cover 24. The negative ion generating component 22 includes an ion carbon brush 221 and an electrode 222. The electrode 222 is disposed between the box body 23 and the second cover 25. The ion carbon brush 221 passes through a hole in the box body 23 and is disposed close to the electrode 222. There are two ion carbon brushes 221, which are arranged on opposite sides of the electrode 222 in a direction away from the negative ion high voltage pack 21. The ion carbon brush 221 is connected to the negative ion emission port to receive the negative voltage provided by the high voltage, and then cooperates with the electrode 222 to ionize the surrounding air and release negative ions.

[0075] The second cover 25 does not contact the electrode 222 and is fixed to the box body 23 as a whole by means of means such as snap-fit ​​connection; in addition, a through hole can be opened on the second cover 25, which can effectively reduce the overall weight of the negative ion generating module 20 without affecting the generation of negative ions.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
