[0084] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0085] The following refers to Figures 1 - 9 Describe the purification component 100 according to an embodiment of the present invention. The purification component 100 can be applied to the purification device 200 and used as a part of the purification device 200. The purification component 100 can also be applied to an air - conditioner and used as a part of the air - conditioner.

[0086] Refer to Figures 1 - 7, the purification component 100 according to the first aspect embodiment of the present invention includes: a purification bracket 1, a first purification module 2, and a second purification module 3. The first purification module 2 and the second purification module 3 are arranged on the purification bracket 1. For example, both the first purification module 2 and the second purification module 3 are detachably mounted on the purification bracket 1. The purification bracket 1 has a ventilation structure 11 that penetrates the purification bracket 1 in the first direction, and external air can flow through the purification component 100 via the ventilation structure 11.

[0087] The first purification module 2 includes an electrostatic dust removal component 21. The first purification module 2 has an electrostatic dust removal function. The electrostatic dust removal component 21 can adsorb particles, dust, etc. in the air flowing through the first purification module 2, and the electrostatic dust removal component 21 can be reused by cleaning and no longer needs to be frequently replaced. The second purification module 3 is detachably mounted on the purification bracket 1, and the purification function of the second purification module 3 is different from that of the first purification module 2. The second purification module 3 and the first purification module 2 can provide users with more purification functions at the same time, meeting the users' more needs for improving air quality. Optionally, the second purification module 3 may have purification functions such as odor removal, dehumidification, formaldehyde removal, harmful bacteria removal, and disinfection. By detachably mounting the second purification module 3 on the purification bracket 1, when the electrostatic dust removal component 21 of the first purification module 2 needs to be cleaned, the second purification module 3 can be removed to avoid unnecessary damage to the second purification module 3 during the cleaning process. For example, when the second purification module 3 includes purification consumables (such as activated carbon, filter screens, etc.), these purification consumables cannot be cleaned. Removing the second purification module 3 when cleaning the purification component of the first purification module 2 can prevent water, cleaning agents, etc. used for cleaning from damaging the purification function of the purification consumables of the second purification module 3.

[0088] For example, the first direction can refer to Figure 10 the up and down direction shown in

[0089] According to the purification component 100 of the embodiment of the present invention, by setting the first purification module 2 and the second purification module 3, and making the first purification module 2 have an electrostatic dust removal function and the second purification module 3 have a purification function different from that of the first purification module 2, the first purification module 2 and the second purification module 3 can meet the users' more needs for improving air quality; and the electrostatic dust removal component 21 of the first purification module 2 can be reused by cleaning, and the first purification module 2 no longer uses consumables and no longer needs to be frequently replaced. Users no longer need to purchase air conditioning equipment equipped with different purification functions, nor do they need to frequently replace the first purification module 2 and the second purification module 3 as a whole. Thus, the purification component 100 can reduce the user's economic cost of use.

[0090] Refer to Figures 1 - 7, according to some embodiments of the present invention, the second purification module 3 includes purification consumables. The second purification module 3 performs other purification functions different from those of the first purification module 2 through these purification consumables. During the use of the purification component 100, the electrostatic dust removal assembly 21 of the first purification module 2 does not need to be frequently replaced. When necessary, only the purification consumables of the second purification module 3 need to be replaced separately, which can also save economic costs for users.

[0091] , according to some embodiments of the present invention, the second purification module 3 has at least one purification function among formaldehyde removal, odor purification, and dehumidification. For example, the second purification module 3 has a purification function of formaldehyde removal, odor purification, or dehumidification. For example, the second purification module 3 has any two purification functions among formaldehyde removal, odor purification, and dehumidification. For example, the second purification module 3 has three purification functions of formaldehyde removal, odor purification, and dehumidification. By enabling the second purification module 3 to have at least one purification function among formaldehyde removal, odor purification, and dehumidification, the purification component 100 can simultaneously have an electrostatic dust removal function and at least one purification function among formaldehyde removal, odor purification, and dehumidification, which can enrich the purification functions of the purification component 100 to better meet the user's demand for improving air quality.

[0092] Reference Figures 1 - 7 , according to some embodiments of the present invention, the purification bracket 1 includes a first bracket 12, a second bracket 13, and a third bracket 14. For example, the first bracket 12 is detachably connected to the second bracket 13, and the first bracket 12 is also detachably connected to the third bracket 14. The second bracket 13 is connected to the first bracket 12 and defines a first accommodation space 4 for accommodating the first purification module 2. For example, the first purification module 2 is accommodated in the first accommodation space 4 and connected to the first bracket 12 or the second bracket 13. For example, the first purification module 2 is accommodated in the first accommodation space 4 and simultaneously connected to the first bracket 12 and the second bracket 13. The third bracket 14 is detachably connected to the first bracket 12 and defines a second accommodation space 5 for accommodating the second purification module 3. For example, the second purification module 3 is accommodated in the second accommodation space 5, and the second purification module 3 is detachably connected to the first bracket 12 or the third bracket 14. For example, the second purification module 3 is accommodated in the first accommodation space 4, and the second purification module 3 is simultaneously detachably connected to the first bracket 12 and the third bracket 14.

[0093] By setting the first bracket 12, the second bracket 13, and the third bracket 14, the first purification module 2 and the second purification module 3 can be respectively connected to the purification bracket 1. The first accommodation space 4 formed by the first bracket 12 and the second bracket 13 can improve the stability and accuracy of the installation relationship between the first purification module 2 and the purification bracket 1. The second accommodation space 5 formed by the first bracket 12 and the third bracket 14 can improve the stability and accuracy of the installation relationship between the second purification module 3 and the purification bracket 1. By respectively connecting the first purification module 2 to the second bracket 13 and the second purification module 3 to the third bracket 14, when only one of the first purification module 2 or the second purification module 3 needs to be repaired, maintained, and replaced, only the first bracket 12 and the second bracket 13 can be disassembled or only the first bracket 12 and the third bracket 14 can be disassembled; when the first purification module 2 needs to be cleaned, the second purification module 3 can also be removed by disassembling the first bracket 12 and the third bracket 14 to avoid damaging the second purification module 3 during the cleaning process.

[0094] Reference Figures 1 - 7 , according to some optional embodiments of the present invention, the second bracket 13 and the third bracket 14 are located on the same side of the first bracket 12 along the first direction, and the second bracket 13 and the third bracket 14 are arranged along the second direction, and the second direction intersects the first direction. Optionally, the second bracket 13 and the third bracket 14 can be integrally formed; or the second bracket 13 and the third bracket 14 are detachably connected; or there is no connection relationship between the second bracket 13 and the third bracket 14. By making the second bracket 13 and the third bracket 14 located on the same side of the first bracket 12 along the first direction, the first accommodation space 4 and the second accommodation space 5 are located on the same side of the first bracket 12 along the first direction, so that the first purification module 2 and the second purification module 3 are arranged on the same side of the first bracket 12 along the first direction, and the first purification module 2 and the second purification module 3 can reasonably utilize the accommodation space inside the purification bracket 1 and be reasonably arranged. Thus, the air entering the purification component 100 along the first direction through the ventilation structure 11 can flow through the first purification module 2 or the second purification module 3, or the air entering the purification component 100 along the first direction through the ventilation structure 11 can flow through the first purification module 2 and the second purification module 3, so that the air is purified by the corresponding purification functional components.

[0095] Reference Figures 1 - 7, according to some alternative embodiments of the present invention, the second bracket 13 and the third bracket 14 are arranged at intervals along the second direction. Such an arrangement facilitates the removal of the second bracket 13 from the first bracket 12. For example, when the first bracket 12 and the second bracket 13 are also detachably connected, and there is no connection relationship between the second bracket 13 and the third bracket 14, the second bracket 13 and the third bracket 14 being arranged at intervals along the second direction facilitates the removal of the second bracket 13 and the third bracket 14 from the first bracket 12 respectively, and can also prevent damage caused by collisions between the second bracket 13 and the third bracket 14 during the removal process.

[0096] For example, the first direction can refer to Figure 10 the up-down direction shown in Figure 10 and the second direction can refer to

[0097] the left-right direction shown in Figures 1 - 7 , according to some alternative embodiments of the present invention, the second bracket 13 is detachably connected to the first bracket 12. For example, the first bracket 12 and the second bracket 13 are detachably connected by means of fastening connection or snap connection. The first purification module 2 is detachable. For example, the first purification module 2 is detachably arranged on the purification bracket 1 by means of fastening connection, snap connection, plug connection, etc. For example, a first buckle 121 is formed on one of the first bracket 12 and the second bracket 13, and a first card hole for snap-connecting with the first buckle 121 is provided on the other. The first bracket 12 and the second bracket 13 form a detachable snap connection relationship through the first buckle 121 and the first card hole. For example, a first card hole is formed on the first bracket 12, and a first buckle 121 is formed on the second bracket 13. The first bracket 12 and the second bracket 13 form a detachable snap connection relationship through the first buckle 121 and the first card hole. By making the second bracket 13 detachably connected to the first bracket 12 and the first purification module 2 detachable, it is convenient to disassemble and assemble the first purification module 2 for maintenance, repair and replacement of the first purification module 2. It is convenient to clean the electrostatic dust removal component 21 by removing the first purification module 2, so as to remove the dust collected by the electrostatic dust removal component 21, etc., so that the first purification module 2 can better play its purification function.

[0098] Reference Figures 3 - 7 , according to some alternative embodiments of the present invention, the electrostatic dust removal component 21 includes dust collecting sheets 212, and the dust collecting sheets 212 are used to collect particles, dust, etc. in the air adsorbed by the electrostatic dust removal component 21. The dust collecting sheets 212 are multiple and arranged at intervals. The air entering the purification component 100 from the ventilation structure 11 of the purification bracket 1 flows through the electrostatic dust removal component 21. Specifically, this air flows through the gaps formed by the multiple dust collecting sheets 212, and the multiple dust collecting sheets 212 can adsorb and collect the particles and dust in this air to play a purification function.

[0099] The dust collecting sheet 212 is connected to at least one of the first support 12 and the second support 13. For example, the dust collecting sheet 212 is connected to the first support 12; for example, the dust collecting sheet 212 is connected to the second support 13; for example, the dust collecting sheet 212 is simultaneously connected to both the first support 12 and the second support 13. By providing the dust collecting sheet 212 and connecting the dust collecting sheet 212 to at least one of the first support 12 and the second support 13, the dust collecting sheet 212 is connected to the purification support 1, so that the electrostatic dust removal assembly 21 is connected to the purification support 1, facilitating the disassembly, assembly and maintenance of the electrostatic dust removal assembly 21.

[0100] Reference Figures 2 - 8 、 Figure 9 , according to some optional embodiments of the present invention, the third support 14 and the first support 12 are connected by a pin structure 6. The pin structure 6 includes a pin rod 61 and a pin hole 62. One of the pin rod 61 and the pin hole 62 is provided on the first support 12 and the other is provided on the third support 14. For example, the pin rod 61 is provided on the first support 12 and the pin hole 62 is provided on the third support 14; or the pin rod 61 is provided on the third support 14 and the pin hole 62 is provided on the first support 12. The pin rod 61 is movable between a locked position and an unlocked position. In the locked position, the pin rod 61 is inserted into the pin hole 62, and in the unlocked position, the pin rod 61 is disengaged from the pin hole 62. When the third support 14 is connected to the first support 12, the pin rod 61 is in the locked position and the pin rod 61 is inserted into the pin hole 62. When the connection between the third support 14 and the first support 12 is released, the pin rod 61 is moved from the locked position to the unlocked position to disengage the pin rod 61 from the pin hole 62. By providing the pin structure 6, a detachable connection relationship is formed between the first support 12 and the third support 14, and this connection relationship is simple, and the connection operation and the disconnection operation are simple.

[0101] Reference Figures 2 - 8 、 Figure 9, according to some alternative embodiments of the present invention, a pin hole 62 is provided on the first bracket 12, a pin rod 61 is provided on the third bracket 14, and the pin structure 6 further includes an elastic member 63. One end of the elastic member 63 is connected to the pin rod 61 and the other end of the elastic member 63 is connected to the third bracket 14. The elastic member 63 is configured to drive the pin rod 61 to move towards the locking position. For example, the elastic member 63 is sleeved on the outer peripheral side of the pin rod 61, and one end of the elastic member 63 abuts against a baffle on the pin rod 61, and the other end of the elastic member 63 abuts against a baffle of the third bracket 14. When the pin rod 61 moves from the locking position to the unlocking position, the elastic member 63 is compressed; when the pin rod 61 is in the unlocking position, the deformation restoring force of the elastic member 63 drives the pin rod 61 to move towards the locking position. By providing the elastic member 63, the pin rod 61 can be automatically restored from the unlocking position to the locking position by the driving of the restoring force of the elastic member 63. And when in the locking position, the elastic member 63 can improve the stability and reliability of the insertion relationship between the pin rod 61 and the pin hole 62, so that the pin rod 61 will not automatically disengage from the pin hole 62, thereby improving the stability and reliability of the connection relationship between the third bracket 14 and the first bracket 12.

[0102] Reference Figures 2 - 8 , Figure 9 , according to some alternative embodiments of the present invention, the pin structure 6 further includes an unlocking handle 64, and the unlocking handle 64 is provided on the outer peripheral side of the pin rod 61. For example, a baffle is formed on the outer peripheral side of the pin rod 61, and when the unlocking handle 64 is provided on the outer peripheral side of the pin rod 61, it can abut against the baffle. When a force is applied to the unlocking handle 64, the unlocking handle 64 can drive the pin rod 61 to move together through the abutting relationship with the baffle. By providing the unlocking handle 64, it is convenient to move the pin rod 61 from the locking position to the unlocking position by applying a force to the unlocking handle 64, thereby facilitating the connection of the third bracket 14 to the first bracket 12 through the pin structure 6 and facilitating the release of the connection relationship between the third bracket 14 and the first bracket 12.

[0103] For example, the operation process of connecting the third bracket 14 to the first bracket 12 through the pin structure 6 is as follows: First, apply a force to the unlocking handle 64 in the second direction. The unlocking handle 64 drives the pin rod 61 to move in the second direction towards the compression direction of the elastic member 63. The pin rod 61 moves from the locking position to the unlocking position, and the elastic member 63 is compressed and deformed in the second direction; then, bring the third bracket 14 close to the first bracket 12 and align the pin rod 61 with the pin hole 62 in the second direction; then, remove the force on the unlocking handle 64. The pin rod 61 moves from the unlocking position to the locking position in the second direction under the driving action of the restoring force of the elastic member 63, and the pin rod 61 is inserted into the pin hole 62. Thus, the third bracket 14 is connected to the first bracket 12 through the pin structure 6.

[0104] For example, the operation process of releasing the connection between the third bracket 14 and the first bracket 12 through the latch structure 6 is as follows: First, apply a force to the unlocking handle 64 in the second direction. The unlocking handle 64 drives the latch rod 61 to move in the second direction towards the direction where the elastic member 63 is compressed and away from the latch hole 62. The latch rod 61 moves from the locked position to the unlocked position, so that the latch rod 61 disengages from the latch hole 62, and the elastic member 63 is compressed and deformed in the second direction. Then, move the third bracket 14 away from the first bracket 12, remove the force on the unlocking handle 64, and the latch rod 61 moves to the locked position under the driving action of the elastic member 63. Thus, the connection between the third bracket 14 and the first bracket 12 is released.

[0105] Next, reference will be made to Figures 10 - 18 to describe the purification device 200 according to an embodiment of the present invention. The purification device 200 can be used alone, or can also be applied to an air conditioner and used as a part of the air conditioner.

[0106] Reference Figures 10 - 13 , the purification device 200 according to the second aspect embodiment of the present invention includes the above-mentioned purification component 100 and a high-voltage power supply 210. There is an electrical connection relationship between the purification component 100 and the high-voltage power supply 210. The high-voltage power supply 210 is electrically connected to the first purification module 2 to supply power to the first purification module 2. By providing the purification component 100 and the high-voltage power supply 210, the high-voltage power supply 210 can supply power to the first purification module 2 of the purification component 100, so that the electrostatic dust removal component of the first purification module 2 can perform the electrostatic dust removal function, and the purification device 200 can perform the purification function to improve the air quality.

[0107] The high-voltage power supply 210 is also called a high-voltage generator and is used to generate high voltage. After the high-voltage power supply 210 raises the voltage, it transmits the raised voltage to the first purification module 2 to meet the high-voltage power consumption requirements of the first purification module 2.

[0108] The purification device 200 according to an embodiment of the present invention has the above-mentioned purification component 100. The purification component 100 is provided with a first purification module 2 and a second purification module 3, and the first purification module 2 has an electrostatic dust removal function, and the second purification module 3 has a purification function different from that of the first purification module 2. The first purification module 2 and the second purification module 3 can meet the user's more needs for improving air quality; and the electrostatic dust removal component 21 of the first purification module 2 can be reused by cleaning, and the first purification module 2 no longer uses consumables and no longer needs to be frequently replaced. The user no longer needs to purchase air conditioning equipment with different purification functions, nor does it need to frequently replace the first purification module 2 and the second purification module 3 as a whole. Thus, the purification component 100 can reduce the user's economic cost of use.

[0109] Reference Figures 10 - 18 According to some embodiments of the present invention, the high-voltage power supply 210 includes a housing 220, a circuit board 235, and an output contact 240. The circuit board 235 is disposed inside the housing 220, and the output contact 240 is mounted on the housing 220. The interior of the housing 220 has an accommodation space, which can be used to arrange components such as the circuit board 235 of the high-voltage power supply 210. The circuit board 235 is disposed in the accommodation space of the housing 220, and the housing 220 provides support and protection for the circuit board 235. The output contact 240 is mounted on the housing 220, and the housing 220 provides support for the output contact 240. The output contact 240 is electrically connected to the circuit board 235. Optionally, the output contact 240 and the circuit board 235 can be disposed inside the housing 220 together.

[0110] The first purification module 2 has a power connection member 22. The output contact 240 of the high-voltage power supply 210 is in electrical contact with the power connection member 22 of the first purification module 2, so that the high-voltage power supply 210 is electrically connected to the first purification module 2. The output contact 240 is used to be in electrical contact with the power connection member 22 of the first purification module 2 to supply power to the first purification module 2. Thus, the output contact 240 forms an electrical connection relationship between the circuit board 235 and the first purification module 2, and the output contact 240 can supply the voltage from the circuit board 235 to the first purification module 2. Among them, both the output contact 240 and the power connection member 22 are conductive members. For example, both the output contact 240 and the power connection member 22 are metal conductive members.

[0111] When electrically connecting the high-voltage power supply 210 and the first purification module 2, by making the output contact 240 of the high-voltage power supply 210 be in electrical contact with the power connection member 22 of the first purification module 2, the electrical connection between the high-voltage power supply 210 and the power supply component can be achieved, eliminating the wiring operation, making the formation method of the electrical connection relationship between the high-voltage power supply 210 and the first purification module 2 simple, easy to operate, and convenient to implement.

[0112] It should be noted that the high-voltage power supply 210 may include two output contacts 240. One of the two output contacts 240 is positive and the other is negative. The first purification module 2 may include two power connection members 22. One of the two power connection members 22 is positive and the other is negative. The two power connection members 22 are respectively in contact with the two output contacts 240.

[0113] Reference Figures 10 - 22, According to some alternative embodiments of the present invention, the output contact piece 240 is located inside the housing 220 and is electrically connected to the circuit board 235. The housing 220 provides support and protection for the output contact piece 240. By arranging the output contact piece 240 inside the housing 220, it is possible to reduce or avoid electric shock accidents caused by accidental contact with the output contact piece 240, etc., and the safety of the high-voltage power supply 210 can be improved. A first avoidance through-hole 221 is formed on the housing 220. The output contact piece 240 includes a contact portion 241 adapted to be in electrical contact with the power connection member 22 of the first purification module 2, and the contact portion 241 is opposite to the first avoidance through-hole 221. The first avoidance through-hole 221 allows the contact portion 241 of the output contact piece 240 to be in electrical contact with the power connection member 22 of the first purification module 2, thereby forming an electrical connection relationship between the high-voltage power supply 210 and the first purification module 2, and the formation manner of this electrical connection relationship is simple, easy to operate, and convenient to achieve. For example, when electrically connecting the high-voltage power supply 210 and the first purification module 2, the power connection member 22 of the first purification module 2 can pass through the first avoidance through-hole 221 and directly contact the contact portion 241 of the output contact piece 240 to form an electrical connection relationship.

[0114] Reference Figure 21 , According to some alternative embodiments of the present invention, the output contact piece 240 includes a fixing portion 242 and a connecting portion 243, and the fixing portion 242 can be connected to one end of the connecting portion 243. The fixing portion 242 is fixed to the housing 220. For example, the fixing portion 242 can be fixed to the housing 220 through fasteners (such as screws, rivets, welding nails, etc.). The contact portion 241 can be connected to the other end of the connecting portion 243. The connecting portion 243 is connected between the contact portion 241 and the fixing portion 242. There is an included angle between the connecting portion 243 and the fixing portion 242. For example, the included angle between the connecting portion 243 and the fixing portion 242 can be 30° - 90°. There is an included angle between the connecting portion 243 and the contact portion 241. For example, the included angle between the connecting portion 243 and the contact portion 241 can be 30° - 90°.

[0115] By arranging the output contact piece 240 to include the above-mentioned fixing portion 242, connecting portion 243, and contact portion 241, the output contact piece 240 can have better elasticity. When electrically connecting the high-voltage power supply 210 and the power supply component, the power connection member 22 of the power supply component can pass through the first avoidance through-hole 221 and directly contact the contact portion 241 of the output contact piece 240. By the power connection member 22 of the power supply component squeezing the output contact piece 240, the output contact piece 240 can be elastically deformed to ensure that the output contact piece 240 of the high-voltage power supply 210 and the power connection member 22 of the power supply component maintain stable contact, thereby forming a stable electrical connection relationship between the high-voltage power supply 210 and the power supply component.

[0116] For example, in some embodiments of the present invention, reference Figure 22, the output contact piece 240 includes the above-mentioned fixing part 242, connecting part 243 and contacting part 241, and the angle between the connecting part 243 and the fixing part 242 of the output contact piece 240 is a right angle, and the angle between the connecting part 243 and the contacting part 241 of the output contact piece 240 is also a right angle. A first avoidance through hole 221 is formed at the top of the housing 220. The first avoidance through hole 221 penetrates the top of the housing 220 in the up and down direction. The connecting part 243 of the output contact piece 240 extends in the up and down direction. The fixing part 242 is connected to the lower end of the connecting part 243, and the contacting part 241 is connected to the upper end of the connecting part 243. The contacting part 241 faces the first avoidance hole, so that the contacting part 241 can be exposed to the outside through the first avoidance hole. The power receiving member 22 of the powered component can be arranged at the bottom of the powered component. When electrically connecting the high-voltage power supply 210 and the powered component, the powered component can be placed above the high-voltage power supply 210, so that the power receiving member 22 of the powered component is directly above the first avoidance through hole 221, and the power receiving member 22 of the powered component contacts the contacting part 241 through the first avoidance through hole 221 and presses the contacting part 241 downward to ensure that the power receiving member 22 and the contacting part 241 maintain stable contact, so as to form a stable electrical connection relationship between the high-voltage power supply 210 and the powered component.

[0117] Reference Figures 21 - 22 , according to some embodiments of the present invention, a support boss 227 is provided inside the housing 220. For example, the support boss 227 can be integrally formed with the housing 220. The support boss 227 includes a support seat 2271 and a support protrusion 2272. The support seat 2271 is fixed to the inner wall of the housing 220. For example, the support seat 2271 can be fixed to the bottom wall of the housing 220. The support protrusion 2272 is provided on the support seat 2271. The fixing part 242 is fixed to the support seat 2271, and the connecting part 243 extends along the side wall of the support boss 227. The support boss 227 provides a supporting effect for the output contact piece 240 through the support seat 2271 and the support protrusion 2272, improving the stability and reliability of the connection relationship between the output contact piece 240 and the housing 220. The contacting part 241 is located on the side of the support protrusion 2272 away from the support seat 2271. When the contacting part 241 is in a natural state, the contacting part 241 is spaced apart from the support protrusion 2272. In this way, the contacting part 241 is located closer to the first avoidance through hole 221 inside the housing 220, facilitating the electrical contact between the output contact piece 240 and the powered component; in addition, through the gap between the contacting part 241 and the support protrusion 2272, a certain deformation space is provided for the output contact piece 240, mainly for the contacting part 241 to provide a certain deformation space, allowing the contacting part 241 of the output contact piece 240 to deform when electrically contacting the power receiving member 22 of the powered component, so that the output contact piece 240 and the power receiving member 22 maintain stable electrical contact.

[0118] Optionally, the support bump 2272 can be integrally formed with the support base 2271. The support base 2271 is fixed to the bottom wall of the housing 220, the support bump 2272 is formed above the support base 2271, the fixing portion 242 extends in the front-rear direction and is fixed to the support base 2271, and the connecting portion 243 extends along the side wall of the support boss 227 in the up-down direction. A first avoidance through-hole 221 is formed at the top of the housing 220. The first avoidance through-hole 221 penetrates the top of the housing 220 in the up-down direction. In the up-down direction, the contact portion 241 is located above the support boss 227, so that the contact portion 241 is opposite to the first avoidance through-hole 221.

[0119] Reference Figures 16 - 18 , according to some optional embodiments of the present invention, the output contact piece 240 is detachably arranged in the housing 220. By detachably arranging the output contact piece 240, it is convenient to replace and maintain the output contact piece 240. For example, the output contact piece 240 can be installed in the housing 220 through a fastener.

[0120] Reference Figures 19 - 21 , according to some optional embodiments of the present invention, the housing 220 includes a main housing 223220 and a cover body 225 that are detachably connected. One side of the main housing 223220 is open, and the cover body 225 is detachably covered on the open side of the main housing 223220. For example, the upper side of the main housing 223220 is open, and the cover body 225 is detachably covered on the upper side of the main housing 223220. The circuit board 235 and the output contact piece 240 are both arranged in the main housing 223220. The first avoidance through-hole 221 is formed in the cover body 225. The first avoidance through-hole 221 can penetrate the cover body 225 in the thickness direction of the cover body 225. For example, the cover body 225 is detachably connected above the main housing 223220, and the first avoidance through-hole 221 is formed as a hole that penetrates the cover body 225 in the up-down direction. By setting the housing 220 to include a detachable main housing 223220 and the housing 220, it is convenient to maintain and replace the components in the housing 220. For example, it is convenient to maintain and replace the circuit board 235, the output contact piece 240, etc. installed in the housing 220. In addition, by providing the cover body 225, it can protect the circuit board 235 and the output contact piece 240 arranged in the main housing 223220, and can improve the safety of the high-voltage power supply 210, avoiding safety accidents caused by accidentally touching the circuit board 235 or the output contact piece 240, etc.

[0121] Reference Figures 16 - 18, according to some alternative embodiments of the present invention, the electrical connection member 22 is a spring piece, and the spring piece is bent in a shape that bends towards the output contact piece 240. Such a setting can enable the electrical connection member 22 to also have the ability of elastic deformation. When the first purification module 2 is in electrical connection with the output contact piece 240 through the electrical connection member 22, the stability of the electrical connection relationship between the first purification module 2 and the output contact piece 240 can be further improved.

[0122] Reference Figures 16 - 22 , according to some alternative embodiments of the present invention, the high-voltage power supply 210 further includes a switch member 250. The switch member 250 is provided in the housing 220 and the switch member 250 is electrically connected to the circuit board 235. Optionally, the switch member 250 and the circuit board 235 can be provided together in the housing 220. The switch member 250 is connected in series to the power supply circuit of the high-voltage power supply 210, and the switch member 250 can control the conduction and disconnection of the power supply circuit by switching between the closed state and the open state. Among them, when the high-voltage power supply 210 is electrically connected to the first purification module 2, the switch member 250 is in the closed state; when the high-voltage power supply 210 is separated from the first purification module 2, the switch member 250 is in the open state.

[0123] When the high-voltage power supply 210 is electrically connected to the first purification module 2, the switch member 250 switches to the closed state to make the power supply circuit conductive, and the high-voltage power supply 210 can supply power to the first purification module 2. When the high-voltage power supply 210 is separated from the contacted part 241, at this time the high-voltage power supply 210 no longer needs to supply power to the first purification module 2. Since the switch member 250 switches to the open state at this time, the power supply circuit in the high-voltage power supply 210 is also disconnected accordingly. In this way, when the first purification module 2 is separated from the high-voltage power supply 210, the high-voltage power supply 210 has a power-off protection function, avoiding accidental injury to the human body caused by the high-voltage power supply 210.

[0124] Reference Figures 16 - 22 , according to some alternative embodiments of the present invention, the switch member 250 is a trigger switch. When the first purification module 2 is electrically connected to the high-voltage power supply 210, the first purification module 2 cooperates with the switch member 250 to trigger the switch member 250 to the closed state. The trigger switch has high reliability and sensitive operation, and can accurately complete the control task of the power supply circuit of the high-voltage power supply 210 and the first purification module 2. The switching between the closed state and the open state of the switch member 250 can be achieved by connecting the first purification module 2 to the high-voltage power supply 210 and disconnecting the first purification module 2 from the high-voltage power supply 210, and no other auxiliary operations are required. Therefore, the control method of the switch member 250 is simple and the operation is convenient.

[0125] Reference Figures 16 - 22, according to some alternative embodiments of the present invention, the switch member 250 is disposed within the housing 220. A second avoidance through-hole 222 is formed on the housing 220. The switch member 250 has a first trigger projection 251 which extends into the second avoidance through-hole 222. The first purification module 2 has a second trigger projection 23. When the second trigger projection 23 contacts and presses the first trigger projection 251, the switch member 250 is triggered to the closed state. When the first purification module 2 is electrically connected to the high-voltage power supply 210, that is, when the power connection member 22 of the first purification module 2 contacts the output contact piece 240 through the first avoidance through-hole 221 to form an electrical connection relationship between the first purification module 2 and the high-voltage power supply 210, the second trigger projection 23 can contact the first trigger projection 251 through the second avoidance through-hole 222. When the second trigger projection 23 contacts and presses the first trigger projection 251, the switch member 250 is triggered to the closed state. Through the cooperation of the contact and pressing between the first trigger projection 251 and the second trigger projection 23, the high-voltage power supply 210 and the first purification module 2 can achieve the state switching of the switch member 250 and the control of the switch member 250 over the power supply circuit. The cooperation method is simple and the operation is convenient. The structures of the first trigger projection 251 and the second trigger projection 23 are simple and the volume is small, and the control task of the switch member 250 can be completed within a relatively small space area.

[0126] For example, the switch member 250 is a microswitch. The microswitch has a spring-type contact as the first trigger projection 251. The microswitch also has a movable contact. The first trigger projection 251 and the movable contact are stacked in the vertical direction, and the first trigger projection 251 is located above the movable contact. When the first trigger projection 251 receives the pressing external force of the second trigger projection 23, the movable contact will be displaced accordingly, so that the microswitch is switched to the closed state.

[0127] According to some alternative embodiments of the present invention, the switch member 250 is detachably disposed within the housing 220, which is convenient for the maintenance and replacement of the switch member 250. For example, an installation post 234 can be provided on one of the switch member 250 and the housing 220, and the other is provided with an installation hole 252. The switch member 250 is detachably disposed on the housing 220 through the cooperation of the installation post 234 and the installation hole 252.

[0128] Reference Figures 19 - 21, According to some embodiments of the present invention, the housing 220 includes a main housing 223220 and a cover 225. A third buckle 2231 is provided on one of the main housing 223220 and the cover 225, and a third buckle hole 2251 that is engaged with the third buckle 2231 is provided on the other. The main housing 223220 and the cover 225 are engaged through the third buckle 2231 and the third buckle hole 2251 to form the housing 220. For example, the third buckle 2231 is provided on the main housing 223220, and the third buckle hole 2251 is provided on the cover 225; for example, the third buckle hole 2251 is provided on the main housing 223220, and the third buckle 2231 is provided on the cover 225. The connection relationship between the main housing 223220 and the cover 225 is simple, which is convenient for installation and disassembly.

[0129] A second guiding plate 226 is formed on the cover 225, and a guiding groove is formed on the main housing 223220. When the cover 225 and the main housing 223220 are assembled, the second guiding plate 226 is adapted to slide along the guiding groove until the second guiding plate 226 is received in the guiding groove. The guiding groove and the second guiding plate 226 are used to guide the cover 225 to slide relative to the main housing 223220, so as to realize the accurate positioning and installation of the main housing 223220 and the cover 225. When the second guiding plate 226 slides until it is completely received in the guiding groove, the third buckle 2231 and the third buckle hole 2251 respectively located on the main housing 223220 and the cover 225 are just engaged, and the cover 225 is connected to the main housing 223220.

[0130] Reference Figures 21 - 22 , According to some embodiments of the present invention, the housing 220 has a first receiving cavity 228 and a second receiving cavity 230 that are separated from each other. The circuit board 235 is disposed in the first receiving cavity 228, and the output contact 240 is located in the second receiving cavity 230. This enables the component layout of the high-voltage power supply 210 to be modularized, which can save space and is convenient for simplifying and optimizing the structure of the high-voltage power supply 210.

[0131] According to some alternative embodiments of the present invention, the first receiving cavity 228 extends in a first direction, the second receiving cavity 230 is located on one side of the first receiving cavity 228 along the first direction and extends in a second direction, and the second direction intersects the first direction. For example, the second direction intersects the first direction. For example, the housing 220 is formed in an L shape, and the two sides of the L shape are respectively formed as the first receiving cavity 228 and the second receiving cavity 230. The two output contacts 240 of the high-voltage power supply 210 are located at both ends of the second receiving cavity 230 along the second direction. The output contacts 240 are spaced apart in the second direction to ensure the safety distance between the two output contacts 240 of the high-voltage power supply 210 and prevent short circuits or other safety accidents from occurring between the two output contacts 240.

[0132] For example, in some embodiments, the first direction is reference Figure 10The left - right direction shown in [reference] is taken as the second direction. Figure 10 The front - back direction shown in [reference].

[0133] Reference Figures 19 - 22 According to a further embodiment of the present invention, the high - voltage power supply 210 further includes a switch member 250. The switch member 250 is disposed in the housing 220 and is electrically connected to the circuit board 235. For example, the switch member 250 is detachably disposed in the housing 220, and the housing 220 has a supporting and protecting effect on the switch member 250. The switch member 250 is connected in series to the power - supply circuit of the high - voltage power supply 210. The switch member 250 is used to control the on - off of the power - supply circuit, which can improve the safety of the power - supply circuit. The switch member 250 is located in the second accommodation cavity 230 and is located between the two output contact pieces 240. By disposing the switch member 250 between the two output contact pieces 240, on the premise of ensuring safety, the design space of the high - voltage power supply 210 can be saved, thereby reducing the volume of the high - voltage power supply 210.

[0134] Reference Figures 16 - 18 and Figure 22 According to some alternative embodiments of the present invention, the input wire harness 270 of the high - voltage power supply 210 leads out from the first accommodation cavity 228. The input wire harness 270 of the high - voltage power supply 210 is located at one end of the first accommodation cavity 228 far from the second accommodation cavity 230, that is, the input wire harness 270 and the second accommodation cavity 230 are respectively located at both ends of the first accommodation cavity 228 in the first direction. In this way, it is convenient for the high - voltage power supply 210 to be connected to an external power supply through the input wire harness 270, and the distance of the input wire harness 270 can be shortened as much as possible. Moreover, the distance between the input end and the output end of the high - voltage power supply 210 is relatively far, reducing the mutual influence between the two, which is conducive to the overall structural layout of the high - voltage power supply 210.

[0135] Reference Figures 10 - 15 According to some alternative embodiments of the present invention, the purification component 100 is located above the high - voltage power supply 210, the output contact piece 240 is located at the top of the high - voltage power supply 210, and the power - connection member 22 is located at the bottom of the purification component 100 and is in electrical contact with the output contact piece 240. When the purification component 100 is electrically connected to the high - voltage power supply 210 and the power - connection member 22 is in contact with the output contact piece 240 through the first avoidance through - hole 221 to form an electrical connection relationship, the stability of the electrical connection relationship between the power - connection member 22 and the output contact piece 240 can be improved; at the same time, by virtue of the self - weight of the purification component 100, the second trigger protrusion 23 can accurately trigger the first trigger protrusion 251 to accurately control the switch member 250 to switch to the closed state.

[0136] Next, refer to Figures 10 - 15 to describe the air conditioner according to the embodiment of the present invention.

[0137] Reference Figures 10 - 14, An air conditioner according to an embodiment of the third aspect of the present invention includes: a housing 310, a heat exchange and air supply assembly, a purification device 200, and an electric control box 313. The housing 310 has an air inlet 311 and an air outlet 312. The heat exchange and air supply assembly is disposed inside the housing 310, and the purification component 100 of the purification device 200 is disposed at the air inlet 311.

[0138] Optionally, the purification component 100 is detachably connected to the housing 310. For example, a second buckle 15 is provided on the first bracket 12, and a second card hole 132 is provided on the front frame 320 of the housing 310. The purification component 100 is detachably connected to the housing 310 through the clamping relationship between the second buckle 15 and the second card hole 132. The electric control box 313 is disposed inside the housing 310. The input wire harness 270 of the high-voltage power supply 210 is electrically connected to the electric control box 313. The electric control box 313 can be electrically connected to an external power supply, and the electric control box 313 can supply power to the high-voltage power supply 210.

[0139] The heat exchange and air supply assembly includes a heat exchanger component and a fan component. When the air conditioner is operating, the fan component drives air to enter the housing 310 from the air inlet 311, exchange heat with the heat exchanger component, and then be discharged from the air outlet 312 to the room, thereby adjusting the room temperature. Among them, when the air conditioner is operating, it is possible to control whether the purification device 200 operates according to needs. When the purification device 200 operates, the high-voltage power supply 210 supplies power to the first purification module 2 of the purification component 100. The electric control box 313 can control whether the electrostatic dust removal assembly 21 of the first purification module 2 operates through the high-voltage power supply 210. If the electrostatic dust removal assembly 21 operates, the purification component 100 can purify part of the air entering the housing 310 to remove particles, dust, etc. mixed in the air entering the housing 310. The purified air is discharged from the air outlet 312, which can improve the indoor air quality. When the purification device 200 operates, the electric control box 313 can also control whether the second purification module 3 of the purification component 100 operates. If the second purification module 3 operates, the second purification module 3 of the purification component 100 can purify another part of the air entering the housing 310, such as removing the odor, formaldehyde, etc. of the air entering the housing 310. The purified air is discharged from the air outlet 312, which can also improve the indoor air quality.

[0140] Among them, the purification component 100 can be disposed at the air inlet 311, or the purification component 100 can be located between the air inlet 311 and the heat exchange and air supply assembly, or the purification component 100 can be disposed between the heat exchanger component and the fan component, or the purification component 100 can be disposed between the fan component and the air outlet 312. During the process of air flowing through the purification component 100, the purification component 100 can purify the air.

[0141] Optionally, the air conditioner may be a split-type air conditioner. For example, the air conditioner may be a split wall-mounted air conditioner. When the air conditioner is a split-type air conditioner, the air conditioner includes an indoor unit 300 and an outdoor unit. The indoor unit 300 includes the above-mentioned housing 310, a heat exchange and air supply assembly, a purification device 200, and an electric control box 313.

[0142] According to the air conditioner of the embodiment of the present invention, the air conditioner has the above-mentioned purification device 200. The purification component 100 of the purification device 200 is provided with a first purification module 2 and a second purification module 3. The first purification module 2 has an electrostatic dust removal function, and the second purification module 3 has a purification function different from that of the first purification module 2. The first purification module 2 and the second purification module 3 can meet the user's more needs for improving air quality. Moreover, the electrostatic dust removal assembly 21 of the first purification module 2 can be reused by cleaning. The first purification module 2 no longer uses consumables and does not need to be frequently replaced. The user no longer needs to purchase air conditioning equipment equipped with different purification functions, nor does the user need to frequently replace the first purification module 2 and the second purification module 3 as a whole. Therefore, the purification component 100 can reduce the user's economic cost of use.

[0143] Reference Figures 10 - 14 , according to some embodiments of the present invention, the ratio of the projection of the first purification module 2 on the air inlet 311 to the area of the air inlet 311 ranges from 1 / 5 to 1 / 2. The first purification module 2 purifies the air entering the air conditioner through the air inlet 311 within the range of 1 / 5 to 1 / 2. If the ratio of the projection of the first purification module 2 on the air inlet 311 to the area of the air inlet 311 is less than 1 / 5, the airflow that can be purified by the first purification module 2 in the airflow entering the air conditioner through the air inlet 311 is less. Then, the proportion of the purified airflow in the airflow entering the room through the air outlet 312 is less, and the improvement and enhancement effect of the purified airflow on the indoor air quality is limited, and it may not meet the user's usage requirements. If the ratio of the projection of the first purification module 2 on the air inlet 311 to the area of the air inlet 311 is greater than 1 / 2, the first purification module 2 is disposed at the air inlet 311, and the first purification module 2 will affect the air flow rate of the air entering the air conditioner through the air inlet 311. The reduction of the air entering the air conditioner through the air inlet 311 causes the air entering the room through the air outlet 312 to decrease, which will further affect the air conditioning effect of the air conditioner, such as affecting the cooling or heating effect of the air conditioner. Moreover, if the ratio of the projection of the first purification module 2 on the air inlet 311 to the area of the air inlet 311 is greater than 1 / 2, the volume of the first purification module 2 increases, which increases the production economic cost of the first purification module 2, and the increased volume of the first purification module 2 will also correspondingly increase the space occupied in the air conditioner, which is not conducive to the miniaturization of the air conditioner.

[0144] Reference Figures 10 - 14, according to some alternative embodiments of the present invention, the ratio of the projection area of the first purification module 2 on the air inlet 311 to the area of the air inlet 311 is 1 / 4. By setting the ratio of the projection area of the first purification module 2 on the air inlet 311 to the area of the air inlet 311 to be 1 / 4, the air entering the air conditioner through the air inlet 311 within this 1 / 4 range can be purified by the first purification module 2. At this time, the proportion of the purified air in the air entering the room through the air outlet 312 is appropriate, and the degree of improvement in the indoor air quality after the purified air enters the room can meet the user's usage requirements. In addition, the volume of the first purification module 2 is also relatively appropriate, without causing high economic costs.

[0145] Reference Figures 10 - 14 , according to some embodiments of the present invention, the ratio range of the sum of the projection areas of the first purification module 2 and the second purification module 3 on the air inlet 311 to the area of the air inlet 311 is 1 / 3 - 2 / 3. The first purification module 2 and the second purification module 3 purify the air entering the air conditioner through the air inlet 311 within this 1 / 3 - 2 / 3 range. If the ratio of the projection areas of the first purification module 2 and the second purification module on the air inlet 311 to the area of the air inlet 311 is less than 1 / 3, then the amount of air flow that can be purified by the first purification module 2 and the second purification module 3 in the air flow entering the air conditioner through the air inlet 311 is small, and the proportion of the purified air flow in the air flow entering the room through the air outlet 312 is small. The improvement and enhancement effect of the purified air flow on the indoor air quality is limited and may not meet the user's usage requirements. If the ratio of the projection areas of the first purification module 2 and the second purification module 3 on the air inlet 311 to the area of the air inlet 311 is greater than 2 / 3, the first purification module 2 and the second purification module 3 are arranged at the air inlet 311, and the first purification module 2 and the second purification module 3 will affect the air flow rate of the air entering the air conditioner through the air inlet 311. The reduction in the air entering the air conditioner through the air inlet 311 causes a decrease in the air entering the room through the air outlet 312, which in turn affects the air conditioning effect of the air conditioner, such as affecting the cooling or heating effect of the air conditioner; and if the ratio of the projection areas of the first purification module 2 and the second purification module 3 on the air inlet 311 to the area of the air inlet 311 is greater than 2 / 3, the volumes of the first purification module 2 and the second purification module 3 will increase correspondingly, resulting in an increase in the production economic costs of the first purification module 2 and the second purification module 3, and the increase in the volumes of the first purification module 2 and the second purification module 3 also increases the space required for arranging the first purification module 2 and the second purification module 3 in the air conditioner, which is not conducive to the miniaturization of the air conditioner.

[0146] Reference Figures 10 - 14, according to some alternative embodiments of the present invention, the sum of the projected areas of the first purification module 2 and the second purification module 3 on the air inlet 311 and the area ratio of the air inlet 311 is 1 / 2. By making the ratio of the projection of the first purification module 2 and the second purification module 3 on the air inlet 311 to the area of the air inlet 311 be 1 / 4, the air entering the air conditioner through the air inlet 311 within this 1 / 4 range can be purified by the first purification module 2 or the second purification module 3. At this time, the proportion of the purified air in the air entering the room through the air outlet 312 is appropriate, and the degree of improvement in the indoor air quality after the purified air enters the room can meet the user's usage requirements. In addition, the volume sizes of the first purification module 2 and the second purification module 3 are also relatively appropriate, and will not cause a high economic cost.

[0147] Reference Figures 10 - 14 , according to some embodiments of the present invention, the air inlet 311 is formed at the top of the housing 310, the air outlet 312 is formed at the front lower part of the housing 310, a negative ion generator is provided at the air outlet 312, and at least one of the first purification module 2 and the second purification module 3 is opposite to the front area of the air inlet 311. For example, the first purification module 2 or the second purification module 3 is opposite to the front area of the air inlet 311. For example, both the first purification module 2 and the second purification module 3 are opposite to the front area of the air inlet 311. When the air flow blows out through the air outlet 312, it will carry the charged ions generated by the negative ion generator at the air outlet 312. Therefore, the air flow containing charged ions will enter the room through the air outlet 312 and adsorb the particles, dust, etc. in the indoor air. Then, part of the air flow containing charged ions will enter the air conditioner again through the air inlet 311. Since the air flow containing charged ions entering the air conditioner again mainly enters through the front area of the air inlet 311. Therefore, at least one of the first purification module 2 and the second purification module 3 is disposed opposite to the front area of the air inlet 311, which also facilitates the air flow containing charged ions to flow through the purification component 100 again for re-purification, thereby improving the overall purification effect of the air conditioner. And by disposing the purification component 100 opposite to the front area of the air inlet 311, the volume of the purification component 100 can also be miniaturized, and the production cost can be saved.

[0148] Reference Figures 10 - 14 , according to some embodiments of the present invention, the high-voltage power supply 210 and the electric control box 313 are located on the same side of the heat exchange and air supply assembly. Such a setting can effectively shorten the distance between the high-voltage power supply 210 and the electric control box 313, facilitate the connection of the high-voltage power supply 210 to the electric control box 313 through the input wire harness 270, reduce the length of the input wire harness 270, and at the same time can also simplify the circuit design between the high-voltage power supply 210 and the electric control box 313 to a certain extent.

[0149] Reference Figures 10 - 14, According to some optional embodiments of the present invention, an air inlet 311 is formed at the top of the casing 310, the purification component 100 is provided at the air inlet 311, the high-voltage power supply 210 and the electric control box 313 are arranged in the vertical direction, the purification component 100 is located above the high-voltage power supply 210, and the high-voltage power supply 210 is located above the electric control box 313. The purification component 100, the high-voltage power supply 210, and the electric control box 313 are compactly and reasonably arranged, which is convenient for the electric control box 313 to supply power to the high-voltage power supply 210. After the high-voltage power supply 210 raises the voltage, the boosted high-voltage power supply 210 is then supplied to the purification component 100. In addition, the arrangement of the high-voltage power supply 210 and the electric control box 313 in the vertical direction makes the wiring harness connected between the high-voltage power supply 210 and the electric control box 313 easy to set and arrange.

[0150] Reference Figures 10 - 14 , According to some optional embodiments of the present invention, the electric control box 313 is located above the air outlet 312, and the electric control box 313 does not affect the air outlet of the air outlet 312. A negative ion generator is provided at the air outlet 312. The negative ion generator is connected to the high-voltage power supply 210 and the negative ion generator is located at one end of the air outlet 312 adjacent to the high-voltage power supply 210. By arranging the negative ion generator at the air outlet 312, it is convenient for the air flowing out through the air outlet 312 to carry the charged ions generated by the negative ion generator into the room to adsorb particles, dust, etc. in the indoor air. The high-voltage power supply 210 supplies power to the negative ion generator so that the negative ion generator generates charged ions. The negative ion generator is arranged adjacent to the high-voltage power supply 210, which can shorten the length of the connection wire harness between the negative ion generator and the high-voltage power supply 210. For example, the negative ion generator and the high-voltage power supply 210 are connected through a negative ion wire harness. By arranging the negative ion generator adjacent to the high-voltage power supply 210, the length of the negative ion wire harness can be shortened, which is convenient for wiring arrangement.

[0151] Reference Figures 10 - 14 , According to some embodiments of the present invention, the casing 310 includes a front frame 320. An installation groove 321 is formed on the front side of the front frame 320. The high-voltage power supply 210 is detachably installed in the installation groove 321 in the front-rear direction. Specifically, the high-voltage power supply 210 can be installed in the installation groove 321 on the front side of the front frame 320 in the direction from front to back; the high-voltage power supply 210 can be disassembled and taken out of the installation groove 321 in the direction from back to front. It is convenient for overhaul and maintenance of the high-voltage power supply 210. By forming the installation groove 321 for installing the high-voltage power supply 210 on the front side of the front frame 320, the installation operation of the high-voltage power supply 210 from the front side of the air conditioner is convenient, and it is also convenient for performing relevant wiring operations on the high-voltage power supply 210, such as wiring operations between the high-voltage power supply 210 and the electric control box 313, and between the high-voltage power supply 210 and the negative ion generator.

[0152] Reference Figures 10 - 15, according to some alternative embodiments of the present invention, a detachable electrical cover 330 is provided on the front side of the electrical control box 313. The electrical cover 330 has a limiting structure 331 for limiting the high-voltage power supply 210. By providing the electrical cover 330, the safety of the air conditioner can be improved. For example, it can prevent safety accidents caused by abnormalities such as electric leakage in the electrical control box 313 and the wire harness. In addition, the electrical cover 330 can also be used to improve the reliability of the wiring between the electrical control box 313, the high-voltage power supply 210, the negative ion generator, etc., and avoid affecting the electrical connection relationship between the electrical control box 313, the high-voltage power supply 210, the negative ion generator, etc. due to accidentally pulling the relevant wire harness. By providing the limiting structure 331, the installation stability of the high-voltage power supply 210 can be improved, and unnecessary movement of the high-voltage power supply 210 relative to the installation groove 321 can be restricted.

[0153] Reference Figures 10 - 15 , according to some alternative embodiments of the present invention, the electrical cover 330 includes a cover body 332, a limiting buckle 334, and a limiting lug 333. The limiting buckle 334 and the limiting lug 333 are connected to one end of the cover body 332 adjacent to the high-voltage power supply 210. The limiting buckle 334 and the limiting lug 333 are arranged close to the high-voltage power supply 210 to facilitate the limiting effect on the high-voltage power supply 210. The high-voltage power supply 210 has a limiting plate 261 extending in the left-right direction and a limiting rib 260 provided on the rear side of the limiting plate 261. The limiting structure 331 includes the limiting lug 333 and the limiting buckle 334. The limiting lug 333 is located on the front side of the high-voltage power supply 210, and the limiting buckle 334 is located on the rear side of the limiting plate 261 and contacts the limiting rib 260 in the left-right direction to limit the high-voltage power supply 210 in the front-rear direction and the left-right direction. Through the cooperation of the limiting lug 333 and the limiting plate 261 and the cooperation of the limiting buckle 334 and the limiting rib, the electrical cover 330 provides a limiting effect on the high-voltage power supply 210 in both the front-rear and left-right directions, so that the high-voltage power supply 210 can be stably installed in the installation groove 321. The cooperation relationship between the limiting lug 333 and the limiting plate 261 and between the limiting buckle 334 and the limiting rib is simple. When the electrical cover 330 is closed to cover the front of the electrical control box 313, the limiting structure 331 can play a limiting role, and the operation is simple.

[0154] For example, the process of installing the high-voltage power supply 210 in the air conditioner is as follows: First, open the electrical cover 330 of the air conditioner, determine the installation state of the high-voltage power supply 210 with reference to the structure and position of the installation groove 321, and place the high-voltage power supply 210 on the front side of the installation groove 321; Next, under the guiding action of the peripheral wall of the installation groove 321, install the high-voltage power supply 210 in the receiving groove 141 in the front-to-back direction on the front side of the front panel 320; Next, electrically connect the input wire harness on the high-voltage power supply 210 to components such as the electronic control box 313 and the negative ion generator; Next, the electrical cover 330 can be closed so that the electrical cover 330 covers the front side of the electronic control box 313 and the input wire harness of the high-voltage power supply 210; Among them, during the process of closing the electrical cover 330, the limit buckle 334 of the electrical cover 330 moves to the rear side of the limit plate 261 and abuts against the limit rib 260 in the left-right direction, and the limit lug 333 of the electrical cover 330 abuts against the front side of the limit plate 261 of the high-voltage power supply 210; The cooperation between the limit lug 333 and the limit plate 261 and the cooperation between the limit buckle 334 and the limit rib make the electrical cover 330 provide a limiting effect on the high-voltage power supply 210 in the front-back and left-right directions. Thus, the high-voltage power supply 210 is installed in the installation groove 321 of the air conditioner.

[0155] For example, the process of removing the high-voltage power supply 210 from the air conditioner is as follows: First, open the electrical cover 330 by moving the electrical cover 330, so that the electronic control box 313 and the input wire harness of the high-voltage power supply 210 are exposed from the front side of the front panel 320, and release the limiting effect of the electrical cover 330 on the high-voltage power supply 210 in the front-back direction and the left-right direction; Next, release the electrical connection between the input wire harness of the high-voltage power supply 210 and the electronic control box 313, etc.; Next, the high-voltage power supply 210 can be removed and taken out from the installation groove 321 in the back-to-front direction from the front side of the front panel 320. Thus, the removal process of the high-voltage power supply 210 is completed.

[0156] According to some optional embodiments of the present invention, the air conditioner further includes a primary filter, and the primary filter is installed at the air inlet 311 and located upstream of the purification component 100. By providing the primary filter, the purification function of the air conditioner can be optimized, and the purification effect of the air conditioner can be improved. The primary filter can be used to filter out a part of the particles, dust, etc. mixed in the air at the air inlet 311 before the air enters the purification component 100, so as to reduce the cleaning and maintenance frequency of the purification component 100 and extend the service life of the purification component 100.

[0157] For example, the purification device 200 can be installed at the air outlet 312 of the casing 310 through the following process: First, the high-voltage power supply 210 needs to be positioned with reference to the installation groove 321 of the front frame 320, and the high-voltage power supply 210 is installed in the installation groove 321; then, the high-voltage power supply 210 can be electrically connected to the electronic control box 313 through the input wire harness 270, and the high-voltage power supply 210 can be electrically connected to the negative ion generator, etc. through the wire harness; then, the electrical cover 330 is closed, so that the electrical cover 330 forms an effective limiting effect on the high-voltage power supply 210; then, the purification component 100 is arranged on the high-voltage power supply 210. Specifically, the purification component 100 is placed at the air inlet 311 and the purification component 100 is located above the high-voltage power supply 210. The electrical connection member 22 of the first purification module 2 of the purification component 100 is electrically connected to the two output contact pieces 240 through the first avoidance through hole 221 and the second avoidance through hole 222 respectively. The second trigger protrusion 23 of the first purification module 2 contacts and presses against the first trigger protrusion 251 to switch the switch member 250 to the closed state; thus far, an electrical connection relationship is formed among the high-voltage power supply 210, the purification component 100, and the electronic control box 313, and the purification device 200 is installed at the air inlet 311 of the casing 310.

[0158] Next, reference will be made to Figures 1 - 18 describe the purification component 100, the purification device 200 having the purification component 100, and the air conditioner having the purification device 200 according to some embodiments of the present invention.

[0159] As Figures 10 - 14 shown, in this embodiment, the air conditioner is a split wall-mounted air conditioner, and the air conditioner includes an air conditioner indoor unit 300 and an air conditioner outdoor unit. The air conditioner indoor unit 300 includes a casing 310, a heat exchange and air supply assembly, a purification device 200, and an electronic control box 313. The casing 310 has an air inlet 311 and an air outlet 312. The air inlet 311 is formed at the top of the casing 310, and the air outlet 312 is formed at the front lower part of the casing 310. The heat exchange and air supply assembly is arranged in the casing 310. The heat exchange and air supply assembly includes a heat exchanger component and a fan component. The fan component drives the air flow to enter the casing 310 from the air inlet 311, exchanges heat with the heat exchanger component, and then is discharged from the air outlet 312 to the room, so that the indoor temperature can be adjusted, for example, the indoor air can be cooled or heated.

[0160] As Figures 10 - 14As shown in the figure, the purification device 200 includes a purification component 100 and a high-voltage power supply 210, and there is an electrical connection relationship between the purification component 100 and the high-voltage power supply 210. The purification component 100 is arranged at the air inlet 311 of the housing 310. A second card hole 132 is formed on the purification component 100, and a second buckle 15 is formed on the front frame 320 of the housing 310. The purification component 100 is detachably connected to the housing 310 through the clamping relationship between the second buckle 15 and the second card hole 132.
