[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 An energy-saving control device for a circulating water pump includes a pump body 1 and a control device 2 located at the water inlet of the pump body 1. The pump body 1 and the control device 2 are connected by a connecting pipe 3. The control device 2 is provided with a flow control component 5 in the water outlet channel of the connecting pipe 3. The connecting pipe 3 is connected to a filter component 4 at the water inlet.

[0022] The flow control component 5 includes a connecting seat 51 and a sealing component 52. The connecting seat 51 and the sealing component 52 are detachably connected by a connecting structure 6. The sealing component 52 is used to block the water outlet channel of the connecting pipe 3.

[0023] Furthermore, the filter assembly 4 includes a filter cover 41, the connecting pipe 3 is fixedly connected to a threaded seat 42 at the water outlet port, the filter cover 41 is threadedly connected to the threaded seat 42, the filter cover 41 is provided with a plurality of filter grooves 43 on its periphery, and the filter cover 41 is provided with a stop part 44 inside.

[0024] Furthermore, the filter assembly 4 also includes a plurality of rubber baffles 45 that fit together. A plurality of through holes are provided on the stop portion 44, and a connecting portion 46 is formed between two adjacent through holes. The rubber baffles 45 are arranged corresponding to the through holes. The top of the rubber baffles 45 is fixedly connected to the connecting portion 46, and the bottom of the rubber baffles 45 abuts against the connecting portion 46. The connecting portion 46 is used to stop the deformation of the rubber baffles 45.

[0025] It should be added that a filter screen can be fixedly connected to the outside of the filter cover 41;

[0026] Furthermore, the top of the rubber baffle 45 is fixedly connected to the connecting part 46, and the bottom of the rubber baffle 45 abuts against the connecting part 46. When the circulating water enters the interior of the connecting pipe 3 through the inlet pipe, the bottom of several rubber baffles 45 deforms due to water pressure. The circulating water is discharged from the filter cover 41 through the filter tank 43, but the particulate impurities in the circulating water are filtered by the filter screen and collected in the filter cover 41.

[0027] Specifically, the aforementioned water inlet pipe is connected to water storage components such as a water storage tank. After the water supply is stopped, the rubber baffle 45 returns to its original shape and, under the action of mutual adhesion, it is in contact with the connection part 46 and cannot deform.

[0028] If the water inlet pipe of connecting pipe 3 is a straight pipe, the rubber baffle 45 is set at the top of the straight pipe to further prevent the backflow of particles. If the water inlet pipe is a bend, several rubber baffles 45 can be closed when the circulating water flows back.

[0029] It is worth mentioning that after rotating and removing the filter cover 41, the filter screen on the outside of the filter cover 41 can be removed, and the particulate impurities inside the filter cover 41 can be cleaned through the filter groove 43. Alternatively, the rubber baffle 45 can be moved to flush out larger particulate impurities from the through hole.

[0030] More specifically, the flow control component 5 also includes a housing 53, within which a drive component 54 is provided. The drive component 54 is used to drive the sealing member 52 to block the water inlet channel between the pump body 1 and the connecting pipe 3.

[0031] Specifically, the drive assembly 54 includes a motor, which is fixedly connected to the side of the housing 53. The motor shaft passes through the housing 53 and is fixedly connected to a lead screw. A guide rod is also fixedly connected inside the housing 53. The connecting seat 51 is threadedly connected to the lead screw and slidably connected to the guide rod. The motor is connected to the control terminal.

[0032] Furthermore, the connecting structure 6 includes an elastic element 61, which is rod-shaped and has an abutment portion 62 and a protrusion portion 63 at both ends. The protrusion portion 63 extends outward along the centerline to connect with the elastic element 61 to form a deformation groove 64.

[0033] Finally, the connecting seat 51 is correspondingly provided with the sealing member 52, and a through hole 55 is provided between the connecting seat 51 and the sealing member 52. The protrusion 63 passes through the through hole 55 through the deformation groove 64, and the protrusion 63 and the abutting part 62 abut against the sides of the connecting seat 51 and the sealing member 52 respectively.

[0034] In this embodiment, the elastic element 61 is preferably made of a material with deformation capability such as rubber or plastic. The protrusion 63 passes through the through hole 55 through the deformation groove 64. Then, the connecting seat 51 and the sealing element 52 achieve a fixing effect under the action of the abutment parts 62 at both ends and the protrusion 63.

[0035] Working method: During operation, circulating water enters the connecting pipe 3 through the inlet pipe and filter cover 41. When it is necessary to control the flow rate of circulating water entering the pump body 1, the motor is controlled to rotate through the control terminal, and the connecting seat 51 drives the sealing part 52 to move under the drive of the lead screw and guide rod.

[0036] When circulating water enters the filter cover 41, the bottom of several rubber baffles 45 deforms under water pressure. The circulating water is discharged from the filter cover 41 through the filter tank 43 and the filter screen. However, the particulate impurities in the circulating water are collected in the filter cover 41 after being filtered by the filter tank 43. After the water supply is stopped, the rubber baffles 45 recover their deformation and, under the action of mutual adhesion, they are in contact with the connecting part 46 and cannot deform, thus achieving the function of collecting particulate impurities.

[0037] Pressing the two protrusions 63 causes them to retract under the action of the deformation groove 64, which allows the elastic element 61 to be pulled out of the through hole 55, enabling the replacement of the sealing element 52.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
