[0002] An air heat source pump is a device that uses the heat energy in the air for heating or cooling. It uses a heat pump circulation system to absorb heat energy from the outdoor air and then transfer it to the indoor space for heating or hot water production. The heater is a device that creates heat energy inside the air heat source pump.

[0003] In the prior art, a filter is installed at the air inlet of the heater to quickly filter out dust and hair in the air. However, as the working time increases, the dust and hair accumulated on the surface of the filter increase, causing the filter holes to be blocked and the air flow rate to decrease. In order to ensure the heat exchange flow, the filter at the air inlet needs to be manually disassembled and cleaned regularly, and then manually installed after cleaning. The operation is cumbersome and reduces the cleaning efficiency of the heater.

[0004] In summary, the present invention provides a heater to solve the above problems. Utility Model Content

[0026] See also Figure 2-5 The negative pressure filtration assembly 7 includes a sealing box 71 and an air pump 72. The sealing box 71 is fixedly connected to one side of the chassis 1, and the air pump 72 is fixedly connected to one side of the chassis 1. An air inlet pipe 73 is connected between the air inlet end of the air pump 72 and the back of the sealing box 71, and an air outlet pipe 74 is connected to the air outlet end of the air pump 72. Two holders 75 are fixedly connected to both sides of the inner wall of the sealing box 71, and a filter plate 76 is clamped between the opposite sides of each two holders 75. The air pump 72 is a device for extracting gas. It extracts gas from a container or system mechanically or electrically to reduce gas pressure or achieve a vacuum state. The vacuum pump 72 is usually composed of a pump body, a driving mechanism, and a gas inlet and outlet.

The air extracted from the sealed box 71 can be filtered through the filter plate 76, and the dust and fluff in the air are filtered through the two filter plates 76 in turn.

[0027] See also Figure 2-6The dust suction pipe group 8 includes a delivery pipe 81, which is connected to the front of the sealing box 71. The top and bottom of the delivery pipe 81 are connected to a connecting pipe 82. The two ends of the two connecting pipes 82 are connected to a corrugated telescopic pipe 83. The two ends of the two corrugated telescopic pipes 83 are connected to a bending pipe 84.

The back of the two bending pipes 84 and the front of the two filter screens 3 are fixedly connected. There is a flat tube 85, and two bent tubes 84 are both bent at right angles. The ends of the two bent tubes 84 away from the corrugated telescopic tube 83 are both blocked. The bent tube 84 is fixedly connected to the movable block 5. The back of the flat tube 85 is open. The bent tube 84 is fixedly connected to the movable block 5. The length of the flat tube 85 is greater than the inner diameter of the mounting ring 2, and the back opening of the flat tube 85 is close to the filter 3, so that the flat tube 85 can move up and down close to the filter 3, and the dust and fluff covering the surface of the filter 3 can be quickly adsorbed and removed.

[0028] Specific implementation method: Through the two air inlets on the front of the chassis 1, outdoor air is sucked in and the heat energy is transferred and utilized through the heat pump circulation system. The dust and fluff in the sucked air can be filtered through the filter screens 3 inside the two mounting rings 2. As the overall working time of the device increases, the dust and fluff accumulated on the surface of the filter screen 3 increases, so it needs to be cleaned. The suction pump 72 inside the negative pressure suction filter component 7 is started, and the air inside the sealed box 71 is sucked through the air inlet pipe 73, so that negative pressure is formed inside the sealed box 71. The tube 81 draws air from the two connecting tubes 82, the two corrugated telescopic tubes 83, the two bent tubes 84 and the two flat tubes 85 in turn. The length of the flat tube 85 is greater than the inner diameter of the mounting ring 2, and the back opening of the flat tube 85 is close to the filter 3, so that the flat tube 85 can move up and down close to the filter 3 while quickly adsorbing and removing the dust and fluff on the surface of the filter 3, and transporting the dust and fluff together with the air to the inside of the sealing box 71, filtering the dust and fluff in the air through two filter plates 76 in turn, and discharging the clean air from the outlet pipe 74.

[0029] At the same time, start the rotation switch at the output end of the electric screw 6. The electric screw 6 is a device that can convert rotational motion into linear motion. It consists of a bidirectional screw and a three-phase asynchronous motor. The motor drives the rotation of the bidirectional screw, so that the two movable blocks 5 make linear motion in opposite directions on the bidirectional screw. When the electric screw 6 rotates clockwise, it can drive the two movable blocks 5 to slide closer to each other on the front side of the chassis 1. When the electric screw 6 rotates counterclockwise, it can drive the two movable blocks 5 to slide away from each other on the front side of the chassis 1. The two movable blocks 5 can drive the two bent tubes 84 to move up and down on the front side of the two filters 3, thereby driving the two flat tubes 85 to move up and down for dust removal, and can automatically clean the filter 3 at the air inlet of the heater, thereby improving the cleaning efficiency of the heater.

[0030] When the filter plates 76 need to be cleaned, the screws on the top of the sealing box 71 can be removed, the box cover can be removed, the sealing box 71 can be opened, and then the two filter plates 76 can be pulled out upward from between the two holders 75 respectively, and then the filter plates 76 can be cleaned.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
