The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0060] Reference below Figure 1-Figure 4 A high voltage power supply 100 according to an embodiment of the present invention is described.

[0061] refer to Figure 1-Figure 4 According to an embodiment of the present invention, a high-voltage power supply 100 comprises: a housing 1, a circuit board 2 and an output contact piece 3, wherein the circuit board 2 is arranged in the housing 1, and the output contact piece 3 is electrically connected to the circuit board 2.

[0062] The housing 1 has a storage space inside, which can be used to set components such as the circuit board 2 of the high-voltage power supply 100. The circuit board 2 is set in the storage space of the housing 1, and the housing 1 supports and protects the circuit board 2. The output contact 3 is set in the housing 1, and the housing 1 supports the output contact 3, and the output contact 3 is electrically connected to the circuit board 2.

[0063] Optionally, the output contact piece 3 may be disposed in the housing 1 together with the circuit board 2 .

[0064] The output contact piece 3 is used to electrically contact with the power receiving part 201 of the powered component 200 to supply power to the powered component 200, so that the output contact piece 3 forms an electrical connection relationship between the circuit board 2 and the powered component 200, and the output contact piece 3 can supply the voltage from the circuit board 2 to the powered component 200. The output contact piece 3 and the power receiving part 201 are both conductive parts, for example, the output contact piece 3 and the power receiving part 201 are both metal conductive parts.

[0065] The high-voltage power supply 100 is also called a high-voltage generator, and is used to generate high voltage. After the high-voltage power supply 100 increases the voltage, the increased voltage is transmitted to the powered component 200 to meet the high-voltage power demand of the power supply component.

[0066] 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.

[0067] According to the high-voltage power supply 100 of the 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 made to electrically contact with the power connector 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 of forming the electrical connection relationship between the high-voltage power supply 100 and the powered component 200 simple, easy to operate, and convenient to realize.

[0068] refer to Figure 1 , Figure 4According to some embodiments of the present invention, the output contact piece 3 is located in the housing 1, and the housing 1 provides support and protection for the supporting component. By arranging the output contact piece 3 in the housing 1, electric shock accidents caused by accidentally touching the output contact piece 3 can be reduced or avoided, and the safety of the high-voltage power supply 100 can be improved. A first avoidance through hole 123 is formed on the housing 1, and the output contact piece 3 includes a contact portion 31 suitable for electrically contacting the power receiving piece 201 of the powered component 200, and the contact portion 31 is opposite to the first avoidance through hole 123. In this way, the first avoidance through hole 123 allows the contact portion 31 of the output contact piece 3 to electrically contact the power receiving piece 201 of the powered component 200, thereby forming an electrical connection relationship between the high-voltage power supply 100 and the powered component 200, 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 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 sheet 3 to form an electrical connection relationship.

[0069] According to some optional embodiments of the present invention, Figure 3 As shown, the output contact piece 3 includes a fixing portion 32 and a connecting portion 33, and the fixing portion 32 can be connected to one end of the connecting portion 33. The fixing portion 32 is fixed to the housing 1, for example, the fixing portion 32 can be fixed to the housing 1 by a fastener (such as a screw, a rivet, a welding nail, etc.). The contact portion 31 can be connected to the other end of the connecting portion 33, and the connecting portion 33 is connected between the contact portion 31 and the fixing portion 32, and there is an angle between the connecting portion 33 and the fixing portion 32, for example, the angle between the connecting portion 33 and the fixing portion 32 can be 30°-90°, and there is an angle between the connecting portion 33 and the contact portion 31, for example, the angle between the connecting portion 33 and the contact portion 31 can be 30°-90°.

[0070] By configuring the output contact piece 3 to include the above-mentioned fixing portion 32, connecting portion 33 and contact portion 31, the output contact piece 3 can have good elasticity. When the high-voltage power supply 100 is electrically connected to the powered component 200, the power receiving piece 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 piece 3. The output contact piece 3 is squeezed by the power receiving piece 201 of the powered component 200 to cause the output contact piece 3 to undergo elastic deformation, thereby ensuring that the output contact piece 3 of the high-voltage power supply 100 maintains stable contact with the power receiving piece 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.

[0071] For example, in some embodiments of the present invention, reference Figure 4The output contact piece 3 includes the above-mentioned fixing portion 32, the connecting portion 33 and the contact portion 31, and the angle between the connecting portion 33 of the output contact piece 3 and the fixing portion 32 is a right angle, and the angle between the connecting portion 33 of the output contact piece 3 and the contact portion 31 is also a right angle. A first avoidance through hole 123 is formed on the top of the housing 1, and the first avoidance through hole 123 penetrates the top of the housing 1 in the up-down direction. The connecting portion 33 of the output contact piece 3 extends in the up-down 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 piece 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 piece 201 of the powered component 200 is located directly above the first avoidance through hole 123, and the power connection piece 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 piece 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.

[0072] According to some optional embodiments of the present invention, reference Figure 3-Figure 4 , a supporting boss 13 is provided in the housing 1, for example, the supporting boss 13 can be integrally formed in the housing 1. The supporting boss 13 includes a supporting seat 131 and a supporting protrusion 132, the supporting seat 131 is fixed to the inner wall of the housing 1, for example, the supporting seat 131 can be fixed to the bottom wall of the housing 1, the supporting protrusion 132 is provided on the supporting seat 131, the fixing portion 32 is fixed to the supporting seat 131, the connecting portion 33 extends along the side wall of the supporting boss 13, the supporting boss 13 provides support for the output contact piece 3 through the supporting seat 131 and the supporting protrusion 132, and improves the stability and reliability of the connection relationship between the output contact piece 3 and the housing 1. The contact portion 31 is located on the side of the supporting protrusion 132 away from the supporting seat 131, and when the contact portion 31 is in a natural state, the contact portion 31 is spaced apart from the supporting protrusion 132. In this way, the contact portion 31 is located in the shell 1 at a position closer to the first avoidance through hole 123, which facilitates the electrical contact between the output contact piece 3 and the powered component 200; in addition, through the interval between the contact portion 31 and the supporting protrusion 132, a certain deformation space is provided for the output contact piece 3, mainly to provide a certain deformation space for the contact portion 31, allowing the contact portion 31 of the output contact piece 3 to deform when it is in electrical contact with the power receiving component 201 of the powered component 200, thereby maintaining stable electrical contact between the output contact piece 3 and the power receiving component 201.

[0073] Optionally, the support protrusion 132 can be formed as one body with the support seat 131, the support seat 131 is fixed to the bottom wall of the shell 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, and the connecting portion 33 extends along the side wall extending in the up-down direction of the support boss 13. A first avoidance through hole 123 is formed at the top of the shell 1, and the first avoidance through hole 123 penetrates the top of the shell 1 in the up-down direction. In the up-down direction, the contact portion 31 is located on the upper side of the support boss 13, so that the contact portion 31 is opposite to the first avoidance through hole 123.

[0074] According to some optional embodiments of the present invention, the output contact piece 3 is detachably arranged in the housing 1. By arranging the output contact piece 3 to be detachable, it is convenient to replace and maintain the output contact piece 3. For example, the output contact piece 3 can be installed on the housing 1 by a fastener.

[0075] According to some optional embodiments of the present invention, reference Figure 1-Figure 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 covered 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 covered on the upper side of the main housing 11. The circuit board 2 and the output contact sheet 3 are both arranged in the main housing 11. The first avoidance through hole 123 is formed in the cover 12. The first avoidance through 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 part of the main housing 11, and the first avoidance through hole 123 is formed as a hole penetrating in the upper and lower directions on the cover 12. By configuring the housing 1 to include a detachable main housing 11 and a housing 1, it is convenient to maintain and replace the components in the housing 1, for example, it is convenient to maintain and replace the circuit board 2, the output contact sheet 3, etc. installed in the housing 1.

[0076] According to some embodiments of the present invention, reference Figure 5-Figure 7 The outer wall of the powered component 200 is provided with a power receiving component 201, which is suitable for electrical contact with the output contact piece 3. The power receiving component 201 is arranged on the outer wall of the powered component 200, so that the power receiving component 201 is in electrical contact with the output contact piece 3.

[0077] According to some optional embodiments of the present invention, Figure 7As shown, the power connection member 201 is a spring sheet, which is bent toward the output contact sheet 3. In this way, the power connection member 201 can also have elastic deformation ability, and when the powered component 200 contacts the output contact sheet 3 through the power connection member 201 to form an electrical connection relationship, the stability of the electrical connection relationship between the powered component 200 and the output contact sheet 3 can be further improved.

[0078] According to some embodiments of the present invention, reference Figure 3-Figure 4 The high-voltage power supply 100 further includes: a switch 4, which is disposed in the housing 1 and is electrically connected to the circuit board 2. Optionally, the switch 4 can be disposed in the housing 1 together with the circuit board 2. The switch 4 is connected in series to the power supply circuit of the high-voltage power supply 100, and the switch 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 4 is in a closed state; when the high-voltage power supply 100 is separated from the powered component 200, the switch 4 is in an open state.

[0079] 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 so that the power supply circuit is turned on, and the high-voltage power supply 100 can 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 does not need to supply power to the powered component 200. Since the switch element 4 is switched to an open state at this time, the power supply circuit in the high-voltage power supply 100 is also disconnected. In this way, 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 to prevent the high-voltage power supply 100 from causing accidental damage to the human body.

[0080] According to some optional embodiments of the present invention, the switch element 4 is a trigger 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. The trigger switch has high reliability and sensitive operation, and can accurately complete the control task of the power supply circuit of the high-voltage power supply 100 and the powered component 200. The switching between the closed state and the open state of the switch element 4 can be achieved by connecting the powered component 200 to the high-voltage power supply 100 and disconnecting the powered component 200 from the high-voltage power supply 100, without the need for other auxiliary operations, so the switch element 4 is simple to control and easy to operate.

[0081] According to some optional embodiments of the present invention, reference Figure 3-Figure 4The switch member 4 is arranged in the housing 1, and a second avoidance through hole 124 is formed on the housing 1. The switch member 4 has a first trigger protrusion 41, and the first trigger protrusion 41 extends into the second avoidance through hole 124. The powered component 200 has a second trigger protrusion 202.

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 supporting 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 supporting 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.

[0104] 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 face frame 402 of the housing 401, the high-voltage power supply 100 needs to be passed through the limit opening 4023 of the face frame 402, and the high-voltage power supply 100 is connected to the face frame 402 by fasteners that are passed through the high-voltage power supply 100 and the support plate 4021; then, the high-voltage power supply 100 can be electrically connected to the electric 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 contact pieces 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 electric control box 404, and the purification device 300 is connected to the housing 401.

Then, part of the airflow containing the charged ions will enter the air conditioner again through the air inlet 405. Since the airflow containing the charged ions entering the air conditioner again mainly enters from the front area of ​​the air inlet, the purification component 301 is arranged relative to the front area of ​​the air inlet 405, so that the airflow containing the charged ions will flow through the purification component 301 again to purify it again, 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.

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 a part of the particles, dust, etc. mixed in the airflow at the air inlet 405 before entering the purification component 301, thereby reducing the cleaning and maintenance frequency of the purification component 301 and extending the service life of the purification component.

[0125] Next, we will refer to Figure 8-Figure 9 , taking the powered component 200 as the purification component 301 as an example, an air conditioner with a high voltage power supply 100 is described. In this embodiment, the air conditioner is a split wall-mounted air conditioner.

The heat exchange and air supply assembly, the purification component 301 , the high voltage power supply 100 and the electric control box 404 are all arranged in the casing 401 .

[0127] The housing 401 extends in the left-right direction, the high-voltage power supply 100 and the electric control box 404 are located on the left side of the housing 401, the heat exchange and air supply assembly is located on the right side of the housing 401, and the purification component 301 is arranged in the housing 401 in the left-right direction. Among them, the electric control box 404 is located on the leftmost side of the housing 401; the high-voltage power supply 100 is arranged adjacent to the electric control box 404, and the high-voltage power supply 100 is electrically connected to the electric control box 404 through the input wiring harness 5; the purification component 301 is arranged above the high-voltage power supply 100, and the left end of the purification component 301 is electrically connected to the high-voltage power supply 100 through the power connector 201 contacting the output contact sheet 3.

[0128] Specifically, the housing 401 includes a face frame 402, and 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 the support plate 4021 extends in a horizontal plane, and a connection hole is provided on the support plate 4021; the limit plate 4022 extends in a vertical plane, and a limit opening 4023 is provided on the limit plate 4022, and the limit opening 4023 is a hole that penetrates in the left-right direction, allowing the high-voltage power supply 100 to pass through in the left-right direction. A lug 113 is provided on the main housing 11 of the high-voltage power supply 100, and the lug 113 is provided at the lower left corner of the main housing 11, and a connection hole in the up-down direction is opened on the lug 113. The high-voltage power supply 100 is installed to the face frame 402 through the limit opening 4023 and the support plate 4021.

[0129] 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:

[0130] First, the high-voltage power supply 100 is passed through the limiting plate 4022 from left to right, and is installed to the face frame 402 through the limiting opening 4023, so that the connection hole on the lug 113 is arranged corresponding to the connection hole on the support plate 4021, and the positioning of the high-voltage power supply 100 relative to the face frame 402 is completed;

[0131] Next, fasteners are passed through the lugs 113 and the support plate 4021 to connect and install the high-voltage power supply 100 to the face frame 402. At this time, the input harness 5 of the high-voltage power supply 100 is close to the electric control box 404, and the high-voltage power supply 100 can be electrically connected to the electric control box 404 through the input harness 5.

[0132] Subsequently, the purification component 301 provided with the power connection piece 201 and the left end of 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 piece 4 of the high-voltage power supply 100 is in a closed state.

[0133] 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.

[0134] 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:

[0135] First, remove the purification component 301 in the up-down direction to disconnect the power receiving component 201 from the output contact piece 3, and at the same time, disengage the second trigger protrusion 202 from the first trigger protrusion 41 and release the pressing effect on the first trigger protrusion 41. At this time, the purification component 301 is disassembled, and the switch element 4 of the high-voltage power supply 100 is switched from the closed state to the open state, so that the power supply circuit between the circuit board 2, the switch element 4 and the output contact piece 3 inside the high-voltage power supply 100 is disconnected, and the high-voltage power supply 100 is in a power-off protection state, which can avoid safety accidents caused by accidental touch when the high-voltage power supply 100 is disassembled next.

[0136] Next, the connection between the input harness 5 of the high-voltage power supply 100 and the electric control box 404 is released, the fasteners passing through the lugs 113 and the support plate 4021 are removed, and the high-voltage power supply 100 is moved from right to left to be disengaged from the limit opening 4023. At this point, the high-voltage power supply 100 is disassembled.
