DETAILED DESCRIPTION

[0053] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0054] The high voltage power supply 100 according to an embodiment of the present invention will be described below with reference to FIG. 1 to FIG. 4 .

[0055] 1 to 4 , a high-voltage power supply 100 according to an embodiment of the present invention includes a housing 1 , a circuit board 2 , and output contacts 3 . The circuit board 2 is disposed in the housing 1 , and the output contacts 3 are electrically connected to the circuit board 2 .

[0056] The housing 1 has a storage space inside for components such as the circuit board 2 of the high-voltage power supply 100. The circuit board 2 is housed within the housing 1, which supports and protects the circuit board 2. Output contacts 3 are located within the housing 1, supporting the output contacts 3 and electrically connecting them to the circuit board 2.

[0057] Optionally, the output contact 3 may be disposed in the housing 1 together with the circuit board 2 .

[0058] The output contact 3 is used to electrically contact the power receiving member 201 of the powered component 200 to supply power to the powered component 200. The output contact 3 thus forms an electrical connection between the circuit board 2 and the powered component 200. The output contact 3 can supply the voltage from the circuit board 2 to the powered component 200. The output contact 3 and the power receiving member 201 are both conductive members, for example, both are metal conductive members.

[0059] The high-voltage power supply 100 is also called a high-voltage generator, which is used to generate high voltage. After the high-voltage power supply 100 increases the voltage, it transmits the increased voltage to the powered component 200 to meet the high-voltage power demand of the power supply component.

[0060] It should be noted that the high-voltage power supply 100 may include two output contacts 3, one of the two output contacts 3 is a positive pole and the other is a negative pole, and the powered component 200 may include two power connectors 201, one of the two power connectors 201 is a positive pole and the other is a negative pole, and the two power connectors 201 are in contact with the two output contacts 3 respectively.

[0061] According to the high-voltage power supply 100 of an embodiment of the present invention, an output contact 3 is provided on the housing 1 of the high-voltage power supply 100 to supply power to the powered component 200. By providing the output contact 3, when the high-voltage power supply 100 is electrically connected to the powered component 200, the output contact 3 on the high-voltage power supply 100 is electrically contacted with the power connection piece 201 of the powered component 200, thereby realizing the electrical connection between the high-voltage power supply 100 and the power supply component, eliminating the wiring operation, and making the method for forming the electrical connection relationship between the high-voltage power supply 100 and the powered component 200 simple, easy to operate, and convenient to implement.

[0062] 1 and 4 , according to some embodiments of the present invention, the output contact 3 is located within the housing 1, which provides support and protection for the supporting component. By arranging the output contact 3 within the housing 1, accidents such as electric shock caused by accidentally touching the output contact 3 can be reduced or avoided, thereby improving the safety of the high-voltage power supply 100. A first avoidance through-hole 123 is formed on the housing 1, and the output contact 3 includes a contact portion 31 suitable for electrically contacting the power receiving component 201 of the powered component 200, with the contact portion 31 facing the first avoidance through-hole 123. In this way, the first avoidance through-hole 123 allows the contact portion 31 of the output contact 3 to electrically contact the power receiving component 201 of the powered component 200, thereby forming an electrical connection between the high-voltage power supply 100 and the powered component 200. The method for forming this electrical connection is simple, easy to operate, and convenient to implement. For example, when the high-voltage power supply 100 is electrically connected to the powered component 200 , the power connector 201 of the powered component 200 can pass through the first avoidance through-hole 123 and directly contact the contact portion 31 of the output contact 3 to form an electrical connection.

[0063] According to some optional embodiments of the present invention, as shown in FIG3 , the output contact 3 includes a fixed portion 32 and a connecting portion 33. The fixed portion 32 can be connected to one end of the connecting portion 33. The fixed portion 32 is fixed to the housing 1. For example, the fixed portion 32 can be fixed to the housing 1 by a fastener (such as a screw, rivet, or weld). The contact portion 31 can be connected to the other end of the connecting portion 33. The connecting portion 33 is connected between the contact portion 31 and the fixed portion 32. The connecting portion 33 and the fixed portion 32 have an angle therebetween. For example, the angle between the connecting portion 33 and the fixed portion 32 can be 30°-90°. The connecting portion 33 and the contact portion 31 have an angle therebetween. For example, the angle between the connecting portion 33 and the contact portion 31 can be 30°-90°.

[0064] By configuring the output contact 3 to include the above-mentioned fixing portion 32, connecting portion 33 and contact portion 31, the output contact 3 can have better elasticity. When the high-voltage power supply 100 is electrically connected to the powered component 200, the power receiving component 201 of the powered component 200 can pass through the first avoidance through-hole 123 and directly contact the contact portion 31 of the output contact 3. The power receiving component 201 of the powered component 200 squeezes the output contact 3, so that the output contact 3 is elastically deformed, ensuring that the output contact 3 of the high-voltage power supply 100 maintains stable contact with the power receiving component 201 of the powered component 200, thereby forming a stable electrical connection relationship between the high-voltage power supply 100 and the powered component 200.

[0065] For example, in some embodiments of the present invention, referring to FIG4 , the output contact 3 includes the aforementioned fixing portion 32, connecting portion 33, and contact portion 31, and the angle between the connecting portion 33 of the output contact 3 and the fixing portion 32 is a right angle, and the angle between the connecting portion 33 of the output contact 3 and the contact portion 31 is also a right angle. A first avoidance through-hole 123 is formed at the top of the housing 1. The first avoidance through-hole 123 passes through the top of the housing 1 in the vertical direction. The connecting portion 33 of the output contact 3 extends in the vertical direction. The fixing portion 32 is connected to the lower end of the connecting portion 33, and the contact portion 31 is connected to the upper end of the connecting portion 33. The contact portion 31 is opposite to the first avoidance hole, so that the contact portion 31 can be exposed to the outside through the first avoidance hole. The power connection member 201 of the powered component 200 can be set at the bottom of the powered component 200. When the high-voltage power supply 100 is electrically connected to the powered component 200, the powered component 200 can be placed above the high-voltage power supply 100, so that the power connection member 201 of the powered component 200 is located directly above the first avoidance through-hole 123, and the power connection member 201 of the powered component 200 contacts the contact portion 31 through the first avoidance through-hole 123, and presses the contact portion 31 downward to ensure that the power connection member 201 maintains stable contact with the contact portion 31, thereby forming a stable electrical connection relationship between the high-voltage power supply 100 and the powered component 200.

[0066] According to some optional embodiments of the present invention, referring to Figures 3 and 4 , a support boss 13 is provided within the housing 1. For example, the support boss 13 can be integrally formed with the housing 1. The support boss 13 includes a support seat 131 and a support protrusion 132. The support seat 131 is fixed to the inner wall of the housing 1, for example, the support seat 131 can be fixed to the bottom wall of the housing 1. The support protrusion 132 is provided on the support seat 131. The fixing portion 32 is fixed to the support seat 131. The connecting portion 33 extends along the sidewall of the support boss 13. The support boss 13 provides support for the output contact 3 through the support seat 131 and the support protrusion 132, thereby improving the stability and reliability of the connection between the output contact 3 and the housing 1. The contact portion 31 is located on the side of the support protrusion 132 away from the support seat 131. When the contact portion 31 is in a natural state, the contact portion 31 is spaced apart from the support protrusion 132. In this way, the contact portion 31 is located in the housing 1 at a position closer to the first avoidance through-hole 123, which facilitates the electrical contact between the output contact 3 and the powered component 200; in addition, the gap between the contact portion 31 and the supporting protrusion 132 provides a certain deformation space for the output contact 3, mainly providing a certain deformation space for the contact portion 31, allowing the contact portion 31 of the output contact 3 to deform when electrically contacting the power receiving component 201 of the powered component 200, thereby maintaining stable electrical contact between the output contact 3 and the power receiving component 201.

[0067] Optionally, the support protrusion 132 can be integrally formed with the support seat 131, with the support seat 131 fixed to the bottom wall of the housing 1. The support protrusion 132 is formed above the support seat 131. The fixing portion 32 extends in the front-to-back direction and is fixed to the support seat 131. The connecting portion 33 extends along the sidewall extending in the vertical direction of the support boss 13. A first avoidance through-hole 123 is formed in the top of the housing 1. The first avoidance through-hole 123 passes through the top of the housing 1 in the vertical direction. In the vertical direction, the contact portion 31 is located on the upper side of the support boss 13, such that the contact portion 31 is opposite the first avoidance through-hole 123.

[0068] According to some optional embodiments of the present invention, the output contact 3 is detachably provided in the housing 1. By arranging the output contact 3 detachably, it is convenient to replace and maintain the output contact 3. For example, the output contact 3 can be mounted on the housing 1 by fasteners.

[0069] According to some optional embodiments of the present invention, referring to Figures 1-3, the housing 1 includes a main housing 11 and a cover 12 that are detachably connected. One side of the main housing 11 is open, and the cover 12 is detachably mounted on the open side of the main housing 11. For example, the upper side of the main housing 11 is open, and the cover 12 is detachably mounted on the upper side of the main housing 11. The circuit board 2 and the output contact pads 3 are both disposed within the main housing 11. A first escape hole 123 is formed in the cover 12. The first escape hole 123 can penetrate the cover 12 along the thickness direction of the cover 12. For example, the cover 12 is detachably connected to the upper side of the main housing 11, and the first escape hole 123 is formed as a hole extending vertically through the cover 12. By configuring the housing 1 to include a detachable main housing 11 and housing 1, maintenance and replacement of components within the housing 1 are facilitated, such as maintenance and replacement of the circuit board 2 and output contact pads 3 installed within the housing 1. In addition, by providing the cover 12, the circuit board 2 and the output contact 3 arranged in the main shell 11 can be protected, and the safety of the high-voltage power supply 100 can be improved to avoid safety accidents caused by accidentally touching the circuit board 2 or the output contact 3.

[0070] According to some embodiments of the present invention, referring to Figures 5-7, a power receiving member 201 is provided on the outer wall of the powered component 200. The power receiving member 201 is adapted to make electrical contact with the output contact 3. The power receiving member 201 is provided on the outer wall of the powered component 200 to facilitate electrical contact between the power receiving member 201 and the output contact 3.

[0071] According to some optional embodiments of the present invention, as shown in FIG7 , the power connection member 201 is a spring, which is curved toward the output contact 3. This allows the power connection member 201 to also have elastic deformation capabilities. When the powered component 200 contacts the output contact 3 through the power connection member 201 to form an electrical connection, the stability of the electrical connection between the powered component 200 and the output contact 3 can be further improved.

[0072] According to some embodiments of the present invention, referring to Figures 3 and 4 , the high-voltage power supply 100 further includes a switch element 4 , which is disposed within the housing 1 and electrically connected to the circuit board 2 . Optionally, the switch element 4 can be disposed within the housing 1 together with the circuit board 2 . The switch element 4 is connected in series with the power supply circuit of the high-voltage power supply 100 , and the switch element 4 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 100 is electrically connected to the powered component 200 , the switch element 4 is in the closed state; when the high-voltage power supply 100 is separated from the powered component 200 , the switch element 4 is in the open state.

[0073] When the high-voltage power supply 100 is electrically connected to the powered component 200, the switch element 4 is switched to a closed state, thereby conducting the power supply circuit and enabling the high-voltage power supply 100 to supply power to the powered component 200. When the high-voltage power supply 100 is separated from the contacted portion 31, the high-voltage power supply 100 no longer needs to supply power to the powered component 200. Since the switch element 4 is switched to an open state, the power supply circuit within the high-voltage power supply 100 is also disconnected. Thus, when the powered component 200 is separated from the high-voltage power supply 100, the high-voltage power supply 100 has a power-off protection function, preventing accidental damage to the human body caused by the high-voltage power supply 100.

[0074] According to some optional embodiments of the present invention, switch element 4 is a trigger-type switch. When the powered component 200 is electrically connected to the high-voltage power supply 100, the powered component 200 cooperates with the switch element 4, and the powered component 200 triggers the switch element 4 to a closed state. Trigger-type switches are highly reliable and operate flexibly, accurately completing the task of controlling the power supply circuits of the high-voltage power supply 100 and the powered component 200. Switching between the closed and open states of switch element 4 is achieved by connecting and disconnecting the powered component 200 from the high-voltage power supply 100, without requiring any additional auxiliary operations. Therefore, the control method of switch element 4 is simple and easy to operate.

[0075] According to some optional embodiments of the present invention, referring to Figures 3 and 4, the switch member 4 is disposed within the housing 1, which is formed with a second avoidance through-hole 124. The switch member 4 has a first trigger protrusion 41, which extends into the second avoidance through-hole 124. The powered component 200 has a second trigger protrusion 202. When the powered component 200 is electrically connected to the high-voltage power supply 100, that is, when the power receiving member 201 of the powered component 200 contacts the output contact 3 through the first avoidance through-hole 123 to form an electrical connection between the powered component 200 and the high-voltage power supply 100, the second trigger protrusion 202 can contact the first trigger protrusion 41 through the second avoidance through-hole 124. When the second trigger protrusion 202 contacts and presses against the first trigger protrusion 41, the switch member 4 is triggered to a closed state. The high-voltage power supply 100 and the powered component 200, through the contact and pressure of the first trigger protrusion 41 and the second trigger protrusion 202, can achieve state switching of the switch element 4 and control of the power supply circuit by the switch element 4. This simple coordination and easy operation. The first trigger protrusion 41 and the second trigger protrusion 202 have a simple structure and a small size, allowing the control of the switch element 4 to be completed in a small space.

[0076] For example, the switch element 4 is a micro switch, which has a spring-loaded contact as a first trigger protrusion 41 and a movable contact. The first trigger protrusion 41 and the movable contact are vertically stacked, with the first trigger protrusion 41 located above the movable contact. When the first trigger protrusion 41 receives the external pressure from the second trigger protrusion 202, the movable contact moves, causing the micro switch to switch to the closed state.

[0077] According to some optional embodiments of the present invention, the switch member 4 is detachably mounted within the housing 1, facilitating maintenance and replacement of the switch member 4. For example, a mounting post 154 may be provided on one of the switch member 4 and the housing 1, and the other may be provided in the mounting hole 42. The switch member 4 is detachably mounted within the housing 1 through the engagement of the mounting post 154 with the mounting hole 42.

[0078] According to some embodiments of the present invention, referring to Figures 1-3, a housing 1 includes a main housing 11 and a cover 12.

For example, the main housing 11 is provided with the snap 111, and the cover 12 is provided with the latch hole 121; for example, the main housing 11 is provided with the latch hole 121, and the cover 12 is provided with the snap 111. The connection between the main housing 11 and the cover 12 is simple, making installation and removal easy.

[0079] A guide plate 122 is formed on the cover 12, and a guide groove 112 is formed on the main housing 11.

The guide groove 112 and the guide plate 122 serve to guide the sliding movement of the cover 12 relative to the main housing 11, achieving accurate positioning and installation of the main housing 11 and the cover 12. When the guide plate 122 slides until it is fully received in the guide groove 112, the latch 111 and the latch hole 121 on the main housing 11 and the cover 12, respectively, are securely engaged, and the cover 12 is connected to the main housing 11.

[0080] According to some embodiments of the present invention, referring to Figures 3 and 4 , a first accommodating cavity 14 and a second accommodating cavity 15 are defined within the housing 1. The circuit board 2 is disposed in the first accommodating cavity 14, and the output contact 3 is located in the second accommodating cavity 15. This allows the component arrangement of the high-voltage power supply 100 to be modularized, saving space and simplifying and optimizing the structure of the high-voltage power supply 100.

[0081] According to some optional embodiments of the present invention, the first accommodating cavity 14 extends along a first direction, the second accommodating cavity 15 is located on one side of the first accommodating cavity 14 along the first direction and extends along a second direction, and the second direction intersects with the first direction, for example, the second direction intersects with the first direction. For example, the housing 1 is formed into an L-shape, and the two sides of the L-shape are respectively formed as the first accommodating cavity 14 and the second accommodating cavity 15. The two output contacts 3 of the high-voltage power supply 100 are located at both ends of the second accommodating cavity 15 along the second direction. The output contacts 3 are spaced apart in the second direction to ensure a safe distance between the two output contacts 3 of the high-voltage power supply 100 and to avoid safety accidents such as short circuits between the two output contacts 3.

[0082] For example, in some embodiments, the first direction is the left-right direction, and the second direction is the front-back direction.

[0083] According to a further embodiment of the present invention, referring to Figures 3 and 4, the high-voltage power supply 100 further includes a switch element 4. The switch element 4 is disposed in the housing 1 and is electrically connected to the circuit board 2. For example, the switch element 4 is detachably disposed in the housing 1, and the housing 1 supports and protects the switch element 4. The switch element 4 is connected in series with the power supply circuit of the high-voltage power supply 100. The switch element 4 is used to control the conduction and disconnection of the power supply circuit, thereby improving the safety of the power supply circuit. The switch element 4 is located in the second accommodating cavity 15 and is located between the two output contacts 3. By arranging the switch element 4 between the two output contacts 3, while ensuring safety, the design space of the high-voltage power supply 100 can be saved, thereby reducing the volume of the high-voltage power supply 100.

[0084] According to some optional embodiments of the present invention, referring to FIG4 , the input wiring harness 5 of the high-voltage power supply 100 is routed outward from the first accommodating chamber 14. The input wiring harness 5 of the high-voltage power supply 100 is located at the end of the first accommodating chamber 14 that is away from the second accommodating chamber 15. That is, the input wiring harness 5 and the second accommodating chamber 15 are respectively located at the two ends of the first accommodating chamber 14 in the first direction. This facilitates the connection of the high-voltage power supply 100 to an external power source via the input wiring harness 5, minimizes the distance of the input wiring harness 5, and further extends the distance between the input and output ends of the high-voltage power supply 100, thereby reducing the mutual influence between the two ends and facilitating the overall structural layout of the high-voltage power supply 100.

The input wiring harness 5 of high-voltage power supply 100 is electrically connected to electrical control box 404. Electrical control box 404 can be electrically connected to an external power supply and can provide power to high-voltage power supply 100.

[0090] 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 airflow from the air inlet 405 into the housing 401, exchanges heat with the heat exchanger component, and then is discharged into the room through the air outlet 406, thereby adjusting the indoor temperature. During operation, the purification device 300 can be controlled to operate as needed. When the purification device 300 is operating, the high-voltage power supply 100 supplies power to the purification component 301, and the electrical control box 404 controls whether the purification component 301 is turned on. If the purification component 301 is turned on, the purification component 301 can purify the air entering the housing 401, and the purified air is discharged through the air outlet 406, thereby improving the indoor air quality.

Furthermore, the electrical connection between the purification component 301 of the purification device 300 and the high-voltage power supply 100 is simple, making it easy to install.

[0094] According to some embodiments of the present invention, referring to Figures 8-10, the high-voltage power supply 100 and the electrical control box 404 are located on the same side of the heat exchange and air supply assembly, which can effectively shorten the distance between the high-voltage power supply 100 and the electrical control box 404, facilitate the high-voltage power supply 100 to be connected to the electrical control box 404 through the input wiring harness 5, reduce the length of the input wiring harness 5, and at the same time simplify the line design between the high-voltage power supply 100 and the electrical control box 404 to a certain extent.

[0095] According to some optional embodiments of the present invention, referring to FIG. 4 and FIG. 8 - FIG. 9 , the input harness 5 is located on a side of the high-voltage power supply 100 adjacent to the electric control box 404 , which can further shorten the length of the input harness 5 .

Part of the high-voltage power supply 100 is located on one side of the electrical control box 404 in the front-to-back direction, and part of the high-voltage power supply 100 is located on the side of the electrical control box 404 adjacent to the heat exchange and air supply assembly. This facilitates the design and layout of the overall circuitry within the air conditioner.

[0097] According to some embodiments of the present invention, referring to Figures 8-9, the housing 401 includes a face frame 402, the high-voltage power supply 100 is installed on the face frame 402, the face frame 402 includes a support plate 4021 and a limit plate 4022, the limit plate 4022 is arranged on the upper side of the support plate 4021, and a limit opening 4023 is provided on the limit plate 4022. The high-voltage power supply 100 is supported on the support plate 4021 and connected to the support plate 4021 of the high-voltage power supply 100, and a portion of the high-voltage power supply 100 is accommodated in the limit opening 4023. By setting the limiting plate 4022 and the limiting opening 4023, the high-voltage power supply 100 can be easily installed and positioned relative to the face frame 402; by setting the support plate 4021, the high-voltage power supply 100 can be provided with stable support and the high-voltage power supply 100 can be easily installed and fixed. By setting the limiting plate 4022 on the support plate 4021 and the limiting opening 4023 on the limiting plate 4022, the reliability of the relative positioning relationship between the high-voltage power supply 100 and the face frame 402 is facilitated; the high-voltage power supply 100 is connected to the face frame 402 of the casing 401, so that when the high-voltage power supply 100 forms a connection relationship with the purification component 301, the face frame 402 provides a certain support for the purification component 301, thereby improving the installation stability of the purification component 301.

[0098] For example, the purification device 300 can be connected to the housing 401 through the following process: first, the high-voltage power supply 100 needs to be positioned with reference to the surface frame 402 of the housing 401, the high-voltage power supply 100 needs to be passed through the limit opening 4023 of the surface frame 402, and fasteners are passed through the high-voltage power supply 100 and the support plate 4021 to connect the high-voltage power supply 100 to the surface frame 402; then, the high-voltage power supply 100 can be electrically connected to the electrical control box 404 through the input wiring harness 5; then, the purification component 301 is set on the high-voltage power supply 100, at this time, the power receiving member 201 of the purification component 301 is electrically connected to the two output contacts 3 through the first avoidance through-hole 123 and the second avoidance through-hole 124 respectively, and the second trigger protrusion 202 contacts and presses the first trigger protrusion 41 to switch the switch member 4 to a closed state; at this point, an electrical connection relationship is formed between the high-voltage power supply 100, the purification component 301 and the electrical control box 404, and the purification device 300 is connected to the housing 401.

[0099] According to some embodiments of the present invention, referring to Figures 9 and 11, an air inlet 405 is formed at the top and the front lower portion of the housing 401. A negative ion generator is provided at the air outlet 406, and the purification component 301 is opposite the front area of ​​the air inlet 405. When the airflow is blown out through the air outlet 406, it carries the charged ions generated by the negative ion generator at the air outlet 406. Therefore, the airflow containing the charged ions will enter the room through the air outlet 406 and absorb particles, dust, etc. in the indoor air. Subsequently, part of the airflow containing the charged ions will re-enter the air conditioner through the air inlet 405. Since the airflow containing the charged ions that re-enters the air conditioner mainly enters the front area of ​​the air inlet, the purification component 301 is arranged opposite the front area of ​​the air inlet 405. This facilitates the airflow containing the charged ions to flow through the purification component 301 again for further purification, thereby improving the overall purification effect of the air conditioner. Furthermore, by arranging the purification component 301 opposite to the front area of ​​the air inlet 405 , the purification component 301 can be miniaturized, thereby saving production costs.

[0100] According to some optional embodiments of the present invention, the air conditioner further includes a primary filter, which is installed at the air inlet 405 and located upstream of the purification component 301. 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 filter out some particles, dust, etc. contained in the airflow at the air inlet 405 before entering the purification component 301, thereby reducing the frequency of cleaning and maintenance of the purification component 301 and extending the service life of the purification component.

The switch element 4 is connected in series with the power supply circuit of the high-voltage power supply 100 and is electrically connected to the circuit board 2. Specifically, the switch element 4 is mounted within the second accommodating chamber 15 and positioned between the two output contacts 3 in the front-to-back direction. Furthermore, to prevent safety issues caused by mutual interference between the output contacts 3 and the switch element 4, the second accommodating chamber 15 is divided into three areas by a partition: a first area 151, a second area 152, and a third area 153. The three areas are arranged in the front-to-back direction.

There are two first escape holes 123, which are arranged in the front-to-back direction, with the second escape hole 124 located between the two first escape holes 123. When the cover 12 is attached to the main housing 11, the first escape hole 123 is positioned vertically opposite the output contact 3, while the second escape hole 124 is positioned vertically opposite the switch element 4. Specifically, the first escape hole 123 is positioned opposite the contact portion 31 of the output contact 3, while the second escape hole 124 is positioned opposite the first triggering protrusion 41 of the switch element 4.

[0111] As shown in Figures 2 and 3, the housing 1 also has a guide structure for accurately securing the cover 12 to the main housing 11.

Guide slot 112 is disposed on the main housing 11. Specifically, guide slot 112 is disposed in second region 152 of the second accommodating cavity 15, such that second region 152 is open toward the left end.

[0112] When the cover 12 is installed in the main housing 11, the guide plate 122 slides vertically relative to the guide slot 112 until the latch 111 is fully engaged with the latch hole 121. At this point, the guide plate 122 forms a closed left end in the second area 152 and acts as a limiter for the switch 4 mounted in the second area 152, ensuring a stable installation within the housing 1.

[0113] As shown in FIG4 , the high-voltage power supply 100 is further provided with an input wiring harness 5.

A power connection element 201 and a second trigger protrusion 202 are provided below the powered component 200. Two power connections 201 are provided, with the second trigger protrusion 202 positioned between the two power connections 201. When the powered component 200 is positioned above the high-voltage power supply 100, the power connection element 201 passes through the first relief hole 123 and contacts the output contact 3, establishing an electrical connection between the powered component 200 and the high-voltage power supply 100. The second trigger protrusion 202 passes through the second relief hole 124 and contacts and presses against the first release protrusion, causing the switch element 4 to switch to the closed state.

[0115] Next, as shown in Figures 5-10 , we will describe the states of the power supply circuit of the high-voltage power supply 100 when the powered component 200 is connected to the high-voltage power supply 100 and when the powered component 200 is disconnected from the high-voltage power supply 100. In this embodiment, the powered component 200 is exemplified by a purification component 301, which, when electrically connected to the high-voltage power supply 100, forms a purification device 300.

[0116] The purification component 301 extends horizontally and includes an upper bracket 3012, a purification element 3011, and a lower bracket 3013.

A second triggering protrusion 202, which contacts and presses against the first triggering protrusion 41, is also located on the underside of the outer wall at the left end of the purification component 301. The second triggering protrusion 202 is located between the two power connectors 201 in the front-to-back direction.

[0117] When the purification component 301 is positioned above the high-voltage power supply 100, it is electrically connected to the power supply 100. The second trigger protrusion 202 contacts and presses against the second trigger protrusion 202, causing the switch element 4 to switch to the closed state. This activates the power supply circuit. The circuit board 2, switch element 4, output contact 3, and purification component 301 are all electrically connected, and the high-voltage power supply 100 supplies power to the purification component 301.

[0118] When the purification component 301 is disconnected from the high-voltage power supply 100, the second trigger protrusion 202 springs up and switches the switch element 4 to the off state, disconnecting the power supply circuit. This disconnects the circuit between the circuit board 2, the switch element 4, and the output contact 3, effectively disconnecting the high-voltage power supply 100 from the circuit board.

The high-voltage power supply 100 is mounted to the face frame 402 via the stop opening 4023 and the support plate 4021.

[0123] The process of installing the high voltage power supply 100 and the purification component 301 to the face frame 402 of the air conditioner is as follows:

[0124] First, pass the high-voltage power supply 100 from left to right through the limiting plate 4022 and install it on the face frame 402 through the limiting opening 4023, so that the connection holes on the lugs 113 correspond to the connection holes on the support plate 4021. At this point, the high-voltage power supply 100 is positioned relative to the face frame 402.

[0125] Next, fasteners are passed through the lugs 113 and the support plate 4021 to connect the high-voltage power supply 100 to the face frame 402. At this point, the input harness 5 of the high-voltage power supply 100 is close to the electrical control box 404, and the high-voltage power supply 100 can be electrically connected to the electrical control box 404 through the input harness 5.

[0126] Subsequently, the left end of the purification component 301 provided with the power connection piece 201 and the second trigger protrusion 202 is brought close to the high-voltage power supply 100, and then the two power connection pieces 201 are passed through the first avoidance through-hole 123 in the up and down directions to be electrically connected to the output contact piece 3 of the high-voltage power supply 100 respectively, and the second trigger protrusion 202 is passed through the second avoidance through-hole 124 to contact with the first trigger protrusion 41 and press the first trigger protrusion 41, so that the switch element 4 of the high-voltage power supply 100 is in a closed state.

[0127] At this time, the electric control box 404, the high voltage power supply 100 and the purification component 301 of the air conditioner are in an electrically connected state.

[0128] When the high-voltage power supply 100 or the purification component 301 of the air conditioner needs to be replaced or maintained, the process of disassembling the purification component 301 and the high-voltage power supply 100 is as follows:

[0129] First, remove the purification component 301 vertically, disconnecting the power connector 201 from the output contact 3. This also causes the second trigger protrusion 202 to disengage from the first trigger protrusion 41, releasing its pressure on the first trigger protrusion 41. At this point, the purification component 301 is completely removed, and the switch element 4 of the high-voltage power supply 100 switches from a closed state to an open state. This disconnects the power supply circuit between the circuit board 2, switch element 4, and output contact 3 within the high-voltage power supply 100, placing the high-voltage power supply 100 in a power-off state. This prevents accidents caused by accidental contact during subsequent disassembly of the high-voltage power supply 100.

[0130] Next, disconnect the input wiring harness 5 of the high-voltage power supply 100 from the electrical control box 404, remove the fasteners passing through the lugs 113 and the support plate 4021, and move the high-voltage power supply 100 from right to left to disengage it from the stopper 4023. At this point, disassembly of the high-voltage power supply 100 is complete.
