[0037] Air energy equipment includes the following types, such as air energy heat pump water heaters, air energy heat pump cooling and heating machines, air energy heat pump desiccant, air energy heat pump dehumidifiers, etc. Air energy equipment is usually installed outdoors to facilitate heat source acquisition, reduce indoor space occupation, ventilation and heat dissipation, and noise control. The power supply used in air energy equipment is usually installed outdoors with the air energy equipment to reduce the length of the wires and power loss, and to facilitate the maintenance of the power supply.

[0038] Since the power supply is installed outdoors and most of them are installed in air energy equipment, if the power supply is damaged due to moisture or the heat dissipation effect is deteriorated and damaged, the power supply needs to be repaired and replaced. Since the power supply is installed in the air energy equipment, if the power supply needs to be repaired and replaced, the air energy equipment needs to be disassembled to expose the power supply. This operation is relatively cumbersome. The main reason for its cumbersomeness is that the air energy equipment needs to be disassembled when replacing the power supply. There are many steps, which increases the workload of the maintenance personnel.

[0039] The utility model provides a power source applied to air energy equipment.

[0040] See also Figure 1 , Figure 2 In one embodiment of the utility model, the power supply used in the air energy device includes a first housing 100, a heat pump and other equipment, wherein the first housing 100 is used for installing the power supply. The power supply includes:

[0041] The second shell 200 is fixed to the first shell 100 , wherein the second shell 200 is fixed to the first shell 100 in a detachable manner, so that the power supply can be easily installed and disassembled.

[0042] The circuit board 400 is detachably mounted on the second shell 200 .

[0043] The third shell 300 covers the circuit board 400 and can be detachably installed on the second shell 200. The third shell 300 is located outside the first shell 100. Since the third shell 300 covers the circuit board 400 and is detachably connected to the second shell 200, when the power supply needs to be inspected and disassembled, it is only necessary to remove the third shell 300. After the third shell 300 is disassembled, the circuit board 400 can be exposed, and the maintenance personnel can repair the circuit board 400. Since the third shell 300 is located outside the first shell 100, when the power supply is inspected, there is no need to disassemble the air energy equipment, thereby reducing the operating steps, reducing the workload of the maintenance personnel, and solving the technical problems existing in the prior art.

[0044] In one embodiment, the second shell 200 includes a protruding ring 210 and a mounting portion 220, and the mounting portion 220 is arranged through the first shell 100, so as to reduce the external structure of the air energy device and avoid the problem that the second shell 200 is too protruding from the air energy device after being installed on the first shell 100, resulting in a larger structure of the air energy device and inconvenience for subsequent installation. The protruding ring 210 abuts against the outside of the first shell 100 and is fixed to the first shell 100, wherein the protruding ring 210 is fixed to the first shell 100 in a detachable manner, and the manner in which the protruding ring 210 is detachably fixed to the first shell 100 is not limited. The circuit board 400 can be detachably installed on the mounting portion 220, wherein the circuit board 400 can be detachably installed on the mounting portion 220 by means of screw locking. At this time, after opening the third shell 300, the circuit board 400 can be removed from the mounting portion 220 by simply removing the screws, that is, the circuit board 400 can be removed from the second shell 200, thereby making it convenient for maintenance personnel to repair and replace the power supply, and the operation is very convenient.

[0045] In one embodiment, reference Figure 3, wherein the annular protrusion 210 can be detachably fixed to the first housing 100 by the following structure, wherein the annular protrusion 210 and the first housing 100 are connected by screw locking. In other embodiments, the annular protrusion 210 and the first housing 100 can also be connected by a buckle assembly, wherein the buckle assembly includes a buckle and a buckle position, wherein the buckle is fixed to the first housing 100, and the buckle position is provided on the annular protrusion 210, and the annular protrusion 210 is fixed to the first housing 100 by the buckle and the buckle position. The buckle assembly can also be used in the following manner, for example, the buckle can also be fixed to the annular protrusion 210, and the buckle position is provided on the first housing 100.

[0046] In one embodiment, reference Figure 3 The third housing 300 is detachably mounted on the annular protrusion 210. Since the annular protrusion 210 abuts against the outside of the first housing 100, the third housing 300 can be directly mounted on the outside of the first housing 100 when it is detachably mounted on the annular protrusion 210. The third housing 300 and the annular protrusion 210 are connected by screw locking.

[0047] In one embodiment, reference Figure 3 , the circuit board 400 is provided with a heat dissipation fin 410, and the mounting portion 220 is provided with a through hole 221, and the through hole 221 is used for the heat dissipation fin 410 to pass through, so that the heat dissipation fin 410 is located inside the first housing 100. In this embodiment, the through hole 221 is provided to facilitate the heat dissipation fin 410 in the circuit board 400 to pass through the mounting plate and enter the first housing 100. For the air energy device, a fan will be provided in its first housing 100. After passing through the through hole 221, the heat dissipation fin 410 of this embodiment will be arranged close to the fan, so that when the fan in the air energy device rotates, it can have a heat dissipation effect on the heat dissipation fin 410.

[0048] In one embodiment, reference Figure 3 The mounting portion 220 is fixed with a mounting ring 240, wherein the mounting ring 240 and the mounting portion 220 are integrally formed, and the mounting ring 240 is arranged around the through hole 221, and the circuit board 400 is mounted on the mounting ring 240 by screw locking. In this way, after the circuit board 400 is fixed on the mounting ring 240 by screw locking, and cooperates with the mounting ring 240, it can have a sealing effect on the through hole 221, thereby preventing a lot of dust from entering the mounting portion 220 through the through hole 221, causing the components on the circuit board 400 to be covered with a lot of dust, affecting its own heat dissipation function.

[0049] In one embodiment, reference Figure 2 , Figure 3The mounting portion 220 is provided with a wire hole 222 for passing the wire inside the first housing 100 through the second housing 200 and connected to the circuit board 400. A dustproof member 230 is installed at the wire hole 222. The dustproof member 230 is provided to prevent dust from entering the mounting portion 220 through the wire hole 222, causing the components on the circuit board 400 to be covered with too much dust, thereby affecting its own heat dissipation effect. The connection wires in the first housing 100 are connected to the circuit board 400 by plug-in connection, that is, the circuit board 400 has a plug-in position reserved for the connection wires in the first housing 100. When connecting the power supply, it is only necessary to insert the connection wires in the first housing 100 into the plug-in position. At the same time, under this structure, when the circuit board 400 needs to be replaced, it is also convenient to separate the connection wires from the circuit board 400. In other embodiments, the connecting wires in the first shell 100 and the circuit board 400 may also be connected by soldering. Thus, when the circuit board 400 is replaced, it is necessary to first use a heating device to remove the solder at the connection or remove the ends of the connecting wires.

[0050] In one embodiment, reference Figure 5 or Figure 6 , the dustproof member 230 is configured as a dustproof ring;

[0051] The dustproof ring is provided with an inner ring 231, an outer ring 232 and a dustproof net 233, wherein the outer ring 232 is fixed to the wire hole 222, wherein the outer ring 232 is fixed to the wire hole 222 by bonding, the inner ring 231 is configured as an elastic member, and the dustproof net 233 is configured as a flexible dustproof material, wherein the flexible dustproof material can be made of polyethylene, polyester fiber, polyurethane, polyvinyl chloride and the like. At the same time, in this embodiment, for the unused wire hole 222, a sealing structure can be connected to the dustproof member 230 by Velcro to block the inner ring 231, thereby preventing dust from entering the mounting portion 220 from the unused inner ring 231.

[0052] In one embodiment, the elastic member is configured to be a rubber material. In other embodiments, the elastic member can also be made of other materials, such as silicone. By providing the elastic member, when the connecting wire in the first shell 100 passes through the dustproof ring, the elastic member can expand the diameter of the inner ring 231 to facilitate the passing of the connecting wire. After the connecting wire passes through, the elastic member can shrink the diameter under the action of its own elastic force, so that the elastic member is attached to the outside of the connecting wire, further reducing the gap between the dustproof ring and the connecting wire, preventing dust from passing through, and further improving the dustproof effect.

[0053] In one embodiment, reference Figure 4, a sealing structure 500 is provided between the first shell 100 and the second shell 200, and between the second shell 200 and the third shell 300. The sealing structure 500 can adopt the following structure, including a convex portion 510 and a concave portion 520. When the above-mentioned sealing structure 500 is used between the first shell 100 and the second shell 200, the convex portion 510 can be provided on the first shell 100 or on the second shell 200. When the convex portion 510 is provided on the first shell 100, the corresponding concave portion 520 is provided on the second shell 200, wherein the convex portion 510 and the concave portion 520 are plugged in, and the plugging between the convex portion 510 and the concave portion 520 can achieve a sealing effect between the two. For the above-mentioned sealing structure 500, the method of applying it between the second shell 200 and the third shell 300 is as described above. In other embodiments, the sealing structure 500 can be configured as a sealing ring.

[0054] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
