Users no longer need to purchase air conditioning equipment equipped with different purification functions, and no longer need to frequently replace the first purification module 2 and the second purification module 3 as a whole, so that the purification component 100 can reduce the user's economic cost of use.

[0090] refer to Figure 1-Figure 7 According to some embodiments of the present invention, the second purification module 3 includes purification consumables. The second purification module 3 uses these purification consumables to perform other purification functions different from those of the first purification module 2. During the use of the purification component 100, the electrostatic dust removal component 21 of the first purification module 2 no longer needs to be replaced frequently.

For example, the second purification module 3 has any two purification functions of removing formaldehyde, odor removal and dehumidification. For example, the second purification module 3 has three purification functions of removing formaldehyde, odor removal and dehumidification. By making the second purification module 3 have at least one purification function of removing formaldehyde, odor removal and dehumidification, the purification component 100 can have an electrostatic dust removal function and at least one purification function of removing formaldehyde, odor removal and dehumidification at the same time, which can enrich the purification function of the purification component 100 to better meet the user's demand for improving air quality.

[0092] refer to Figure 1-Figure 7According to some embodiments of the utility model, 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 and the third bracket 14 are also detachably connected. The second bracket 13 is connected to the first bracket 12 and defines a first accommodating space 4 for accommodating the first purification module 2. For example, the first purification module 2 is accommodated in the first accommodating space 4 and is connected to the first bracket 12 or the second bracket 13. For example, the first purification module 2 is accommodated in the first accommodating space 4 and is 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 accommodating space 5 for accommodating the second purification module 3. For example, the second purification module 3 is accommodated in the second accommodating 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 accommodating space 4, and the second purification module 3 is simultaneously detachably connected to the first bracket 12 and the third bracket 14.

[0093] By providing 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 connected to the purification bracket 1 respectively.

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 accommodating space 4 and the second accommodating 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 use the accommodating space in the purification bracket 1 and make a reasonable layout. Thus, the air entering the purification component 100 along the first direction via 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 via 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] refer to Figure 1-Figure 7 According to some optional embodiments of the utility model, 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 are arranged at intervals along the second direction, which facilitates the removal of the second bracket 13 and the third bracket 14 from the first bracket 12, and can also avoid collisions between the second bracket 13 and the third bracket 14 during the removal process.

[0096] For example, the first direction can refer to Fig.10 The up and down directions shown in the second direction can refer to Fig.10 Left-right direction as shown in .

For example, the dust collecting sheet 212 is connected to the first bracket 12; for example, the dust collecting sheet 212 is connected to the second bracket 13; for example, the dust collecting sheet 212 is connected to both the first bracket 12 and the second bracket 13. By providing the dust collecting sheet 212 and connecting the dust collecting sheet 212 to at least one of the first bracket 12 and the second bracket 13, the dust collecting sheet 212 is connected to the purification bracket 1, and the electrostatic dust removal assembly 21 is connected to the purification bracket 1, which facilitates the disassembly and maintenance of the electrostatic dust removal assembly 21.

[0100] refer to Figure 2-Figure 8 , Fig. 9According to some optional embodiments of the utility model, the third bracket 14 is connected to the first bracket 12 through a latch structure 6, and the latch structure 6 includes a latch rod 61 and a latch hole 62, one of which is provided at the first bracket 12 and the other is provided at the third bracket 14. For example, the latch rod 61 is provided at the first bracket 12, and the latch hole 62 is provided at the third bracket 14; or the latch rod 61 is provided at the third bracket 14, and the latch hole 62 is provided at the first bracket 12. The latch rod 61 is movable between a locking position and an unlocking position, in which the latch rod 61 is inserted into the latch hole 62, and in which the latch rod 61 is disengaged from the latch hole 62. When the third bracket 14 is connected to the first bracket 12, the latch rod 61 is in the locking position, and the latch rod 61 is inserted into the latch hole 62. When the connection between the third bracket 14 and the first bracket 12 is released, the latch rod 61 is moved from the locking position to the unlocking position, so that the latch rod 61 is disengaged from the latch hole 62. By providing the latch structure 6, a detachable connection relationship is formed between the first bracket 12 and the third bracket 14, and the connection relationship is simple, and the connection operation and the contact connection operation are simple.

[0101] refer to Figure 2-Figure 8 , Fig. 9 According to some optional embodiments of the utility model, a latch hole 62 is provided on the first bracket 12, a latch rod 61 is provided on the third bracket 14, and the latch structure 6 further includes an elastic member 63, one end of the elastic member 63 is connected to the latch rod 61 and the other end of the elastic member 63 is connected to the third bracket 14, and the elastic member 63 is used to drive the latch rod 61 to move toward the locked position. For example, the elastic member 63 is sleeved on the outer peripheral side of the latch rod 61, and one end of the elastic member 63 abuts against the baffle on the latch rod 61, and the other end of the elastic member 63 abuts against the baffle of the third bracket 14. When the latch rod 61 moves from the locked position to the unlocked position, the elastic member 63 is compressed; when the latch rod 61 is in the unlocked position, the deformation restoring force of the elastic member 63 drives the latch rod 61 to move toward the locked position. By providing the elastic member 63, the latch rod 61 can be automatically restored from the unlocked position to the locked position by the driving of the restoring force of the elastic member 63. In the locked position, the elastic member 63 can improve the stability and reliability of the plug-in relationship between the latch rod 61 and the latch hole 62, so that the latch rod 61 will not automatically disengage from the latch hole 62, thereby improving the stability and reliability of the connection relationship between the third bracket 14 and the first bracket 12.

[0102] refer to Figure 2-Figure 8 , Fig. 9According to some optional embodiments of the utility model, the latch structure 6 further includes an unlocking handle 64, which is disposed on the outer peripheral side of the latch rod 61. For example, a baffle is formed on the outer peripheral side of the latch rod 61, and the unlocking handle 64 can abut against the baffle when it is disposed on the outer peripheral side of the latch rod 61. When a force is applied to the unlocking handle 64, the unlocking handle 64 can drive the latch rod 61 to move together through the abutment relationship with the baffle. By providing the unlocking handle 64, it is convenient to move the latch rod 61 from the locked position to the unlocked 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 latch 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 latch structure 6 is as follows: first, a force is applied to the unlocking handle 64 along the second direction, and the unlocking handle 64 drives the latch rod 61 to move along the second direction toward the pressure direction of the elastic member 63, and the latch rod 61 moves from the locked position to the unlocked position, and the elastic member 63 is compressed and deformed along the second direction; then, the third bracket 14 is brought close to the first bracket 12 and the latch rod 61 faces the latch hole 62 along the second direction; then, the force on the unlocking handle 64 is removed, and the latch rod 61 moves from the unlocked position to the locked position along the second direction under the driving action of the restoring force of the elastic member 63, and the latch rod 61 is inserted into the latch hole 62. Thus, the third bracket 14 is connected to the first bracket 12 through the latch structure 6.

[0104] For example, the operation process of releasing the connection between the third bracket 14 and the first bracket 12 by the latch structure 6 is as follows: first, a force is applied to the unlocking handle 64 along the second direction, and the unlocking handle 64 drives the latch rod 61 to move along the second direction toward the direction where the elastic member 63 is compressed and away from the latch hole 62, and the latch rod 61 moves from the locked position to the unlocked position, so that the latch rod 61 is separated from the latch hole 62, and the elastic member 63 is compressed and deformed along the second direction; then, the third bracket 14 is moved away from the first bracket 12, and the force on the unlocking handle 64 is removed, and the latch rod 61 moves to the locked position under the driving action of the elastic member 63. As a result, the connection between the third bracket 14 and the first bracket 12 is released.

[0105] Next, we will refer to Figure 10-Figure 18 The purification device 200 according to the embodiment of the present invention is described. The purification device 200 can be used alone, and the purification device 200 can also be applied to an air conditioner and used as a part of the air conditioner.

[0106] refer to Figure 10-13According to the purification device 200 of the second embodiment of the utility model, the purification component 100 and the high-voltage power supply 210 are electrically connected to each other. 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 setting 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 play an electrostatic dust removal function, so that the purification device 200 can play a purification function to improve 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 increases the voltage, the increased voltage is transmitted to the first purification module 2 to meet the high-voltage power demand of the first purification module 2 .

[0108] According to the purification device 200 of the embodiment of the utility model, the purification device 200 has the above-mentioned purification component 100, and 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 the first purification module 2, and 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. Users no longer need to purchase air conditioning equipment equipped with different purification functions, and no longer need to frequently replace the first purification module 2 and the second purification module 3 as a whole, so that the purification component 100 can reduce the user's economic cost of use.

[0109] refer to Figure 10-Figure 18 According to some embodiments of the utility model, the high-voltage power supply 210 includes a housing 220, a circuit board 235 and an output contact piece 240, the circuit board 235 is arranged in the housing 220, and the output contact piece 240 is installed in the housing 220. The housing 220 has a storage space inside, which can be used to set the circuit board 235 and other components of the high-voltage power supply 210. The circuit board 235 is arranged in the storage space of the housing 220, and the housing 220 supports and protects the circuit board 235. The output contact piece 240 is installed in the housing 220, and the housing 220 supports the output contact piece 240, and the output contact piece 240 is electrically connected to the circuit board 235. Optionally, the output contact piece 240 can be arranged in the housing 220 together with the circuit board 235.

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

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

[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 a positive pole and the other is a negative pole, the first purification module 2 may include two power connectors 22, one of the two power connectors 22 is a positive pole and the other is a negative pole, and the two power connectors 22 are in contact with the two output contacts 240 respectively.

[0113] refer to Figure 10-Figure 22 According to some optional embodiments of the utility model, the output contact sheet 240 is located in the housing 220 and is electrically connected to the circuit board 235. The housing 220 provides support and protection for the output contact sheet 240. By arranging the output contact sheet 240 in the housing 220, electric shock accidents caused by accidentally touching the output contact sheet 240 can be reduced or avoided, 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, and the output contact sheet 240 includes a contact portion 241 suitable for electrically contacting the power receiving 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 sheet 240 to electrically contact the power receiving 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 method of the electrical connection relationship is simple, easy to operate, and convenient to implement. For example, when the high-voltage power supply 210 is electrically connected to the first purification module 2, the power connector 22 of the first purification module 2 may pass through the first avoidance through hole 221 and directly contact the contact portion 241 of the output contact sheet 240 to form an electrical connection relationship.

[0114] refer to Fig.21According to some optional 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 by a fastener (such as a screw, a rivet, a welding nail, etc.). The contact portion 241 can be connected to the other end of the connecting portion 243, and the connecting portion 243 is connected between the contact portion 241 and the fixing portion 242, and there is an angle between the connecting portion 243 and the fixing portion 242, for example, the angle between the connecting portion 243 and the fixing portion 242 can be 30°-90°, and there is an angle between the connecting portion 243 and the contact portion 241, for example, the angle between the connecting portion 243 and the contact portion 241 can be 30°-90°.

[0115] By configuring the output contact 240 to include the above-mentioned fixing portion 242, connecting portion 243 and contact portion 241, the output contact 240 can have good elasticity. When the high-voltage power supply 210 is electrically connected to the powered component, the power receiving component 22 of the powered component can pass through the first avoidance through hole 221 and directly contact the contact portion 241 of the output contact 240. The output contact 240 is squeezed by the power receiving component 22 of the powered component to cause the output contact 240 to undergo elastic deformation, thereby ensuring that the output contact 240 of the high-voltage power supply 210 maintains stable contact with the power receiving component 22 of the powered component, thereby forming a stable electrical connection relationship between the high-voltage power supply 210 and the powered component.

[0116] For example, in some embodiments of the present invention, reference Fig. 22The output contact piece 240 includes the above-mentioned fixing portion 242, the connecting portion 243 and the contact portion 241, and the angle between the connecting portion 243 and the fixing portion 242 of the output contact piece 240 is a right angle, and the angle between the connecting portion 243 and the contact portion 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 shell 220, and the first avoidance through hole 221 penetrates the top of the shell 220 in the up-down direction. The connecting portion 243 of the output contact piece 240 extends in the up-down direction, the fixing portion 242 is connected to the lower end of the connecting portion 243, and the contact portion 241 is connected to the upper end of the connecting portion 243. The contact portion 241 is opposite to the first avoidance hole, so that the contact portion 241 can be exposed to the outside through the first avoidance hole. The power connection piece 22 of the powered component can be set at the bottom of the powered component. When the high-voltage power supply 210 is electrically connected to the powered component, the powered component can be placed above the high-voltage power supply 210, so that the power connection piece 22 of the powered component is located directly above the first avoidance through hole 221, and the power connection piece 22 of the powered component contacts the contact portion 241 through the first avoidance through hole 221, and presses the contact portion 241 downward to ensure that the power connection piece 22 maintains stable contact with the contact portion 241, thereby forming a stable electrical connection relationship between the high-voltage power supply 210 and the powered component.

The supporting boss 227 includes a supporting seat 2271 and a supporting protrusion 2272, the supporting seat 2271 is fixed to the inner wall of the housing 220, for example, the supporting seat 2271 can be fixed to the bottom wall of the housing 220, the supporting protrusion 2272 is provided on the supporting seat 2271, the fixing portion 242 is fixed to the supporting seat 2271, the connecting portion 243 extends along the side wall of the supporting boss 227, and the supporting boss 227 provides support for the output contact sheet 240 through the supporting seat 2271 and the supporting protrusion 2272, thereby improving the stability and reliability of the connection relationship between the output contact sheet 240 and the housing 220. The contact portion 241 is located on the side of the support protrusion 2272 away from the support seat 2271. When the contact portion 241 is in a natural state, the contact portion 241 is spaced apart from the support protrusion 2272. In this way, the contact portion 241 is located in the housing 220 closer to the first avoidance through hole 221, which facilitates the electrical contact between the output contact piece 240 and the powered component; in addition, the spacing between the contact portion 241 and the support protrusion 2272 provides a certain deformation space for the output contact piece 240, mainly providing a certain deformation space for the contact portion 241, allowing the contact portion 241 of the output contact piece 240 to deform when in electrical contact with the power receiving component 22, thereby maintaining stable electrical contact between the output contact piece 240 and the power receiving component 22.

[0118] Optionally, the support protrusion 2272 can be formed as one body with the support seat 2271, the support seat 2271 is fixed to the bottom wall of the housing 220, the support protrusion 2272 is formed above the support seat 2271, the fixing portion 242 extends in the front-to-back direction and is fixed to the support seat 2271, and the connecting portion 243 extends along the side wall extending in the up-down direction of the support boss 227. A first avoidance through hole 221 is formed at the top of the housing 220, and 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 on the upper side of the support boss 227, so that the contact portion 241 is opposite to the first avoidance through hole 221.

[0119] refer to Figure 16-Figure 18 According to some optional embodiments of the present invention, the output contact sheet 240 is detachably disposed in the housing 220. By detachably arranging the output contact sheet 240, it is convenient to replace and maintain the output contact sheet 240. For example, the output contact sheet 240 can be mounted on the housing 220 by fasteners.

[0120] refer to Figure 19-21 According to some optional embodiments of the utility model, the housing 220 includes a main housing 223220 and a cover 225 that are detachably connected. One side of the main housing 223220 is open, and the cover 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 225 is detachably covered on the upper side of the main housing 223220. The circuit board 235 and the output contact sheet 240 are both arranged in the main housing 223220. The first avoidance through hole 221 is formed in the cover 225. The first avoidance through hole 221 can penetrate the cover 225 along the thickness direction of the cover 225. For example, the cover 225 is detachably connected to the upper side of the main housing 223220, and the first avoidance through hole 221 is formed as a hole penetrating the cover 225 in the up-down direction. By configuring 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 and the output contact sheet 240 installed in the housing 220. In addition, by configuring the cover 225, the circuit board 235 and the output contact sheet 240 arranged in the main housing 223220 can be protected, and the safety of the high-voltage power supply 210 can be improved to avoid safety accidents caused by accidentally touching the circuit board 235 or the output contact sheet 240.

[0121] refer to Figure 16-Figure 18According to some optional embodiments of the present invention, the electrical connection member 22 is a spring sheet, which is bent toward the output contact sheet 240. This arrangement allows the electrical connection member 22 to also have elastic deformation capability, and when the first purification module 2 is in contact with the output contact sheet 240 through the electrical connection member 22 to form an electrical connection relationship, the stability of the electrical connection relationship between the first purification module 2 and the output contact sheet 240 can be further improved.

[0122] refer to Figure 16-Figure 22 According to some optional embodiments of the utility model, the high-voltage power supply 210 further includes a switch 250, which is disposed in the housing 220 and is electrically connected to the circuit board 235. Optionally, the switch 250 can be disposed in the housing 220 together with the circuit board 235. The switch 250 is connected in series to the power supply circuit of the high-voltage power supply 210, and the switch 250 can control the conduction and disconnection of the power supply circuit by switching between a closed state and an open state. When the high-voltage power supply 210 is electrically connected to the first purification module 2, the switch 250 is in a closed state; when the high-voltage power supply 210 is separated from the first purification module 2, the switch 250 is in an open state.

[0123] When the high-voltage power supply 210 is electrically connected to the first purification module 2, the switch 250 is switched to a closed state so that the power supply circuit is turned on, 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 portion 241, the high-voltage power supply 210 no longer needs to supply power to the first purification module 2. Since the switch 250 is switched to an open state at this time, the power supply circuit in the high-voltage power supply 210 is also disconnected. 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 to prevent the high-voltage power supply 210 from causing accidental damage to the human body.

[0124] refer to Figure 16-Figure 22 According to some optional embodiments of the utility model, the switch 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 250 so that the switch 250 is triggered to a closed state. The trigger switch has high reliability and sensitive operation, and can accurately complete the control task of the high-voltage power supply 210 and the power supply circuit of the first purification module 2. The switching between the closed state and the open state of the switch 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 250 is simple and easy to operate.

The switch member 250 has a first trigger protrusion 251, and the first trigger protrusion 251 extends into the second avoidance through hole 222. The first purification module 2 has a second trigger protrusion 23. When the second trigger protrusion 23 contacts and presses the first trigger protrusion 251, the switch member 250 is triggered to a closed state. When the first purification module 2 is electrically connected to the high-voltage power supply 210, that is, when the power receiving part 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 protrusion 23 can contact the first trigger protrusion 251 through the second avoidance through hole 222, and when the second trigger protrusion 23 contacts and presses the first trigger protrusion 251, the switch part 250 is triggered to a closed state. The high-voltage power supply 210 and the first purification module 2 can realize the state switching of the switch part 250 and the control of the power supply circuit by the switch part 250 through the contact and pressing of the first trigger protrusion 251 and the second trigger protrusion 23, and the cooperation method is simple and easy to operate. The first trigger protrusion 251 and the second trigger protrusion 23 have a simple structure and a small volume, and can complete the control task of the switch part 250 in a small space area.

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

[0127] According to some optional embodiments of the present invention, the switch member 250 is detachably disposed in the housing 220, which is convenient for maintenance and replacement of the switch member 250. For example, a mounting post 234 may be disposed on one of the switch member 250 and the housing 220, and the other may be disposed on the mounting hole 252, and the switch member 250 may be detachably disposed on the housing 220 through the cooperation of the mounting post 234 and the mounting hole 252.

The connection relationship between the main housing 223220 and the cover 225 is simple, and it is easy to install and disassemble.

[0129] A second guide plate 226 is formed on the cover 225, and a guide groove is formed on the main housing 223220. When the cover 225 and the main housing 223220 are assembled, the second guide plate 226 is adapted to slide along the guide groove until the second guide plate 226 is accommodated in the guide groove. The guide groove and the second guide plate 226 are used to guide the cover 225 to slide relative to the main housing 223220, so as to achieve accurate positioning and installation of the main housing 223220 and the cover 225. When the second guide plate 226 slides to be completely accommodated in the guide groove, the third buckle 2231 and the third clamping 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.

This makes the arrangement of components of the high-voltage power supply 210 modular, saves space, and facilitates simplification and optimization of the structure of the high-voltage power supply 210.

[0131] According to some optional embodiments of the utility model, the first accommodating cavity 228 extends along the first direction, the second accommodating cavity 230 is located on one side of the first accommodating cavity 228 along the first direction and extends along the second direction, and the second direction intersects with the first direction, for example, the second direction intersects with the first direction. For example, the shell 220 is formed into an L-shape, and the two sides of the L-shape are respectively formed into the first accommodating cavity 228 and the second accommodating cavity 230. The two output contacts 240 of the high-voltage power supply 210 are located at both ends of the second accommodating cavity 230 along the second direction. The output contacts 240 are arranged at intervals in the second direction to ensure a safe distance between the two output contacts 240 of the high-voltage power supply 210 and to avoid safety accidents such as short circuits between the two output contacts 240.

The switch component 250 is located in the second accommodating cavity 230 and the switch component 250 is located between the two output contacts 240. The switch component 250 is disposed between the two output contacts 240. Under 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.

In this way, it is convenient for the high-voltage power supply 210 to be connected to an external power source through the input harness 270, and the distance of the input harness 270 can be shortened as much as possible, and the distance between the input end and the output end of the high-voltage power supply 210 is made longer, reducing the mutual influence between the two, and facilitating the overall structural layout of the high-voltage power supply 210.

Among them, when the air conditioner is working, it is possible to control whether the purification device 200 is working as needed. When the purification device 200 is working, the high-voltage power supply 210 supplies power to the first purification module 2 of the purification component 100, and the electric control box 313 can control whether the electrostatic dust removal component 21 of the first purification module 2 is working through the high-voltage power supply 210. If the electrostatic dust removal component 21 is working, 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, and the purified air is discharged from the air outlet 312, which can improve the indoor air quality. When the purification device 200 is working, the electrical control box 313 can also control whether the second purification module 3 of the purification component 100 is working. If the second purification module 3 is working, the second purification module 3 of the purification component 100 can purify another part of the air entering the casing 310, such as removing odor, formaldehyde, etc. from the air entering the casing 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 arranged at the air inlet 311, the purification component 100 can also be located between the air inlet 311 and the heat exchange and air supply component, or the purification component 100 can be arranged between the heat exchanger component and the fan component, or the purification component 100 can be arranged between the fan component and the air outlet 312. In the process of air flowing through the purification component 100, the purification component 100 can purify the air.

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

[0142] According to the air conditioner of the embodiment of the utility model, the air conditioner has the above-mentioned purification device 200, and the purification component 100 of the purification device 200 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 the first purification module 2, and 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. Users no longer need to purchase air conditioning equipment equipped with different purification functions, and no longer need to frequently replace the first purification module 2 and the second purification module 3 as a whole, so that the purification component 100 can reduce the user's economic cost of use.

[0143] refer to Figure 10-Figure 14 According to some embodiments of the utility model, 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 in the range of 1 / 5 to 1 / 2, and 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 purified by the first purification module 2 in the airflow entering the air conditioner through the air inlet 311 is relatively small, and the proportion of the airflow purified in the airflow entering the room through the air outlet 312 is relatively small, and the purified airflow has limited effect on improving and enhancing the indoor air quality, which may not meet the user's use 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 arranged at the air inlet 311, and the first purification module 2 will affect the air flow rate entering the air conditioner through the air inlet 311. The reduction of air entering the air conditioner through the air inlet 311 reduces the air entering the room through the air outlet 312, which in turn affects the air conditioning effect of the air conditioner, for example, the cooling or heating effect of the air conditioner; and 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 space occupied by the increased volume of the first purification module 2 in the air conditioner will also increase accordingly, which is not conducive to the miniaturization of the air conditioner.

[0144] refer to Figure 10-Figure 14 According to some optional embodiments of the utility model, 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 1 / 4. By making the ratio of the projection of the first purification module 2 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 the 1 / 4 range can be purified by the first purification module 2. At this time, the proportion of purified air in the air entering the room through the air outlet 312 is appropriate, and the improvement of the indoor air quality after the purified air enters the room can meet the user's use needs. In addition, the size of the first purification module 2 is also relatively appropriate, and will not cause high economic costs.

[0145] refer to Figure 10-Figure 14 According to some embodiments of the utility model, the ratio 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 in the range of 1 / 3 to 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 the range of 1 / 3 to 2 / 3. If the ratio of the projections 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 less than 1 / 3, the airflow purified by the first purification module 2 and the second purification module 3 in the airflow entering the air conditioner through the air inlet 311 is small, and the proportion of the purified airflow in the airflow entering the room through the air outlet 312 is small, and the purified airflow has limited effect on improving and enhancing the indoor air quality, which may not meet the user's use requirements. If 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 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 entering the air conditioner through the air inlet 311. The reduction of air entering the air conditioner through the air inlet 311 will also reduce the air entering the room through the air outlet 312, which will further affect the air conditioning effect of the air conditioner, for example, the cooling or heating effect of the air conditioner; and if 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 is greater than 2 / 3, the volumes of the first purification module 2 and the second purification module 3 will increase accordingly, so that the production economic cost of the first purification module 2 and the second purification module 3 is increased, and the increase in the volumes of the first purification module 2 and the second purification module 3 will increase 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] refer to Figure 10-Figure 14According to some optional embodiments of the utility model, the ratio 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 / 2. By making 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 be 1 / 4, the air entering the air conditioner through the air inlet 311 within the 1 / 4 range can be purified by the first purification module 2 or the second purification module 3. At this time, the proportion of purified air in the air entering the room through the air outlet 312 is appropriate, and the improvement of the indoor air quality after the purified air enters the room can meet the user's use needs. In addition, the size of the first purification module 2 and the second purification module 3 is also relatively appropriate, and will not cause high economic costs.

[0147] refer to Figure 10-Figure 14 According to some embodiments of the utility model, 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, the first purification module 2 and the second purification module 3 are both opposite to the front area of ​​the air inlet 311. When the airflow is blown out through the air outlet 312, it will carry the charged ions generated by the negative ion generator at the air outlet 312, so the airflow containing the charged ions will enter the room from the air outlet 312 and adsorb particles, dust, etc. in the indoor air. Then, part of the airflow containing the charged ions will enter the air conditioner again through the air inlet 311, because the airflow containing the charged ions that enters the air conditioner again mainly enters from 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 arranged opposite to the front area of ​​the air inlet 311, so that the airflow containing charged ions can flow through the purification component 100 again to purify it again, thereby improving the overall purification effect of the air conditioner. In addition, the purification component 100 is arranged opposite to the front area of ​​the air inlet 311, which can also make the purification component 100 smaller in size and save production costs.

[0148] refer to Figure 10-Figure 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.

The layout of the purification component 100, the high-voltage power supply 210 and the electric control box 313 is compact and reasonable, which is convenient for the electric control box 313 to supply power to the high-voltage power supply 210, and the high-voltage power supply 210 increases the voltage and then supplies the boosted high-voltage power supply 210 to the purification component 100. In addition, the high-voltage power supply 210 and the electric control box 313 are arranged in the up-down direction, so that the wiring harness connected between the high-voltage power supply 210 and the electric control box 313 is easy to set and arrange.

By arranging the negative ion generator at the air outlet 312, it is convenient for the air flowing out of 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 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 by a negative ion harness. By arranging the negative ion generator adjacent to the high-voltage power supply 210, the length of the negative ion harness can be shortened, which is convenient for wiring arrangement.

It is convenient to inspect and maintain the high-voltage power supply 210.

[0152] refer to Figure 10-15According to some optional embodiments of the utility model, the front cover of the electric control box 313 is provided with a detachable electric cover 330, and the electric cover 330 has a limiting structure 331 for limiting the high-voltage power supply 210. By providing the electric cover 330, the safety of the air conditioner can be improved, for example, safety accidents caused by abnormalities such as leakage in the electric control box 313 and the wiring harness can be avoided; in addition, the electric cover 330 can also be used to improve the reliability of the wiring between the electric control box 313, the high-voltage power supply 210, the negative ion generator, etc., and avoid affecting the electrical connection relationship between the electric control box 313, the high-voltage power supply 210, the negative ion generator, etc. due to accidentally pulling the relevant wiring harness. By providing the limiting structure 331, the stability of the installation of the high-voltage power supply 210 can be improved, and the high-voltage power supply 210 can be limited from unnecessary movement relative to the installation slot 321.

Through the cooperation between the limiting lug 333 and the limiting plate 261 and the limiting buckle 334 and the limiting protruding rib, the electric cover 330 provides a limiting function for the high-voltage power supply 210 in the front-back and left-right directions, so that the high-voltage power supply 210 can be stably installed in the installation slot 321. The cooperation relationship between the limiting lug 333 and the limiting plate 261 and the limiting buckle 334 and the limiting protruding rib is simple, and the limiting structure 331 can play a limiting role when the electric cover 330 is closed so that the electric cover 330 covers the front of the electric control box 313, 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; then, under the guidance of the peripheral wall of the installation groove 321, install the high-voltage power supply 210 in the receiving groove 141 from front to back on the front side of the face frame 320; then, electrically connect the input wiring harness on the high-voltage power supply 210 to the electric control box 313, the negative ion generator and other components; then, the electrical cover 330 can be closed to make The electrical cover 330 covers the front side of the electrical control box 313 and the input wiring harness of the high-voltage power supply 210; wherein, in the process of closing the electrical cover 330, the limiting buckle 334 of the electrical cover 330 moves to the rear side of the limiting plate 261 and abuts against the limiting rib 260 in the left-right direction, and the limiting lug 333 of the electrical cover 330 abuts against the front side of the limiting plate 261 of the high-voltage power supply 210; the cooperation between the limiting lug 333 and the limiting plate 261 and the cooperation between the limiting buckle 334 and the limiting rib enables the electrical cover 330 to provide a limiting effect on the high-voltage power supply 210 in both the front-to-back and left-to-right directions. Thus, the high-voltage power supply 210 is installed in the installation slot 321 of the air conditioner.

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.

[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 surface 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 electric control box 313 through the input wiring harness 270, and the high-voltage power supply 210 can be electrically connected to the negative ion generator, etc. through the wiring 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 set on the high-voltage power supply 210, specifically , place the purification component 100 at the air inlet 311 and make the purification component 100 located above the high-voltage power supply 210, the power receiving 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, and the second triggering protrusion 23 of the first purification module 2 contacts and presses against the first triggering protrusion 251 to switch the switch member 250 to a closed state; at this point, an electrical connection relationship is formed between the high-voltage power supply 210, the purification component 100 and the electric control box 313, and the purification device 200 is installed at the air inlet 311 of the casing 310.
