Detailed implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-6 , the present invention provides a technical solution: an air source heat pump system, including a heat pump housing 1 and a filter device 2. One side of the heat pump housing 1 is connected to the filter device 2, and one side of the filter device 2 is connected to a valve 3. A cover plate 4 is installed at the top of the filter device 2, and a sealing ring 5 is also provided between the cover plate 4 and the filter device 2. A filter element 6 is arranged below the cover plate 4, and a push plate 7 is arranged below the filter element 6. And the push plate 7 is inside the filter device 2. A spring a 8 is arranged between the push plate 7 and the filter device 2. A snap ring 10 is arranged inside the filter device 2, and the snap ring 10 is connected to a check valve head 9. The check valve head 9 is also inside the filter device 2. A spring b 11 is arranged between the check valve head 9 and the filter device 2. A ball valve 12 is also arranged inside the filter device 2;

[0025] The side of the heat pump housing 1 is provided with a cold water injection pipe 101 and a hot water discharge pipe 102, and is connected to the filter device 2 through the cold water injection pipe 101, which is beneficial for the water flow filtered by the filter device 2 to enter the heat pump housing 1 through the cold water injection pipe 101;

[0026] Two flow channels 201 that intersect at the head and tail are arranged inside the filter device 2, which is beneficial for the alternate use of the two flow channels 201, so that the filter element 6 inside the heat pump housing 1 can be replaced without stopping the machine;

[0027] Two slide grooves 202 are arranged inside the filter device 2, and the filter device 2 and the filter element 6 form a sliding structure through the slide grooves 202, which is beneficial for the filter element 6 to slide in the slide grooves 202 so as to be installed on the filter device 2;

[0028] The top end of the cover plate 4 is provided with a handle 401, which is beneficial to opening the cover plate 4 by lifting the handle 401;

[0029] The one-way valve head 9 and the snap ring 10 form a sliding structure, and a flow channel 1001 is provided on the snap ring 10, which is beneficial to the unidirectional flow of water, and enables the water flow not to backflow into another flow channel 201 after passing through the filter element 6 in one side flow channel 201, thus affecting the replacement operation of the filter element 6 on the other side;

[0030] The ball valve 12 and the filtering device 2 form a rotating structure, and a guiding hole 1201 and a rotating disc 1202 are provided on the ball valve 12, which is beneficial to controlling the rotation of the ball valve 12 by rotating the rotating disc 1202, so that the guiding hole 1201 provided inside guides the water flow to change direction.

[0031] Working principle: According to Figures 1-6 , after the device has been used for a period of time and the filter element 6 needs to be replaced, first remove the bolts at the cover plate 4 and open it by lifting the handle 401. It should be noted that the opened cover plate 4 is on the side of the flow channel 201 that is not in use. Then, under the action of the spring a8, the push plate 7 will push out the original filter element 6 inside. Next, replace a new filter element 6 and install the cover plate 4 back. Then rotate the rotating disc 1202 to make the internal ball valve 12 rotate, so that the water flow changes direction through the guiding hole 1201, and the water flow will flow to the newly replaced filter element 6, thus completing the filtering operation. The water flow passing through the filter element 6 will push the one-way valve head 9 and pass through the flow channel 1001, and then enter the heat pump housing 1 through the cold water injection pipe 101. The above is the entire working process of the device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
