The pump body 100 includes a diaphragm pump chamber 101, a flexible water inlet pipeline 102 and a flexible water outlet pipeline 103 that are communicated with the diaphragm pump chamber 101. An elastic diaphragm 104 is arranged on one side of the diaphragm pump chamber 101; the pipeline opening and closing component includes a first elastic extrusion member 201 and a second elastic extrusion member 202 for extruding the flexible water inlet pipeline 102 and the flexible water outlet pipeline 103, a first decompression transmission component for relieving the extrusion of the first elastic extrusion member 201 on the flexible water inlet pipeline 102, and a second decompression transmission component for relieving the extrusion of the second elastic extrusion member 202 on the flexible water outlet pipeline 103;The driving device 300 includes a driving source 301 and a linkage assembly 302 connected to the driving source 301 for driving the elastic diaphragm 104 to reciprocate. The driving source 301 can drive the first decompression transmission assembly and the second decompression transmission assembly to relieve the extrusion of the flexible water inlet pipe 102 and the flexible water outlet pipe 103 by the first elastic extrusion member 201 and the second elastic extrusion member 202. Optionally, both the flexible water inlet pipe 102 and the flexible water outlet pipe 103 are rubber hoses, and the driving source 301 is a motor. Further, when the driving source 301 drives the linkage assembly 302 to suck fluid into the diaphragm pump chamber 101, it simultaneously drives the first decompression transmission assembly to relieve the extrusion of the flexible water inlet pipe 102 by the first elastic extrusion member 201. When the driving source 301 drives the linkage assembly 302 to discharge fluid from the diaphragm pump chamber 101, it simultaneously drives the second decompression transmission assembly to relieve the extrusion of the flexible water outlet pipe 103 by the second elastic extrusion member 202. When the diaphragm pump chamber 101 of the present utility model performs a water absorption action, the extrusion of the flexible water inlet pipe 102 by the first elastic extrusion member 201 can be relieved, so that fluid can enter the diaphragm pump chamber 101 through the flexible water inlet pipe 102, and the extrusion of the flexible water outlet pipe 103 by the second elastic extrusion member 202 is not relieved, closing the elastic water outlet pipe. This can effectively prevent external impurities from flowing back into the diaphragm pump chamber 101 during the water absorption process, and is also beneficial for sucking in more sewage. During the drainage stage, the extrusion of the flexible water outlet pipe 103 by the second elastic extrusion member 202 is relieved to ensure the smooth discharge of sewage. At the same time, the extrusion of the flexible water inlet pipe 102 by the first elastic extrusion member 201 prevents the intrusion of external impurities caused by pressure fluctuations during the drainage process. Further, the method of squeezing the flexible water inlet pipe 102 and the flexible water outlet pipe 103 by the first elastic extrusion member 201 and the second elastic extrusion member 202 to close the flexible water inlet pipe 102 and the flexible water outlet pipe 103 is relatively gentle. When there are hard object impurities in the flexible water inlet pipe 102 and the flexible water outlet pipe 103, the first elastic extrusion member 201 and the second elastic extrusion member 202 will not rigidly squeeze the flexible water inlet pipe 102 and the flexible water outlet pipe 103, avoiding damage to the first elastic extrusion member 201, the second elastic extrusion member 202, the flexible water inlet pipe 102, and the flexible water outlet pipe 103.;

Further, through rotational movement, the eccentric wheel 302.1 directly converts the power of the driving source 301 into the reciprocating movement of the connecting rod 302.2. This conversion method reduces energy loss and improves the efficiency of power transmission. Due to the precise cooperation between the eccentric wheel 302.1 and the connecting rod 302.2, it can ensure that the elastic diaphragm 104 reciprocates along a predetermined trajectory and frequency, thus ensuring the stable operation of the pump.

The driving source 301 is disposed outside the housing 400, and the driving end of the driving source 301 extends into the interior of the housing 400 through the connection through-hole 401. The second decompression transmission assembly includes a driving wheel 204.1 disposed on the driving end of the driving source 301, and a driven wheel 204.2 rotatably disposed on the inner wall of the housing 400 and meshing with the driving wheel 204.1. When the driving end of the driving source 301 rotates, it will drive the driving wheel 204.1 to rotate in the same direction. At this time, the driving wheel 204.1 will drive the driven wheel 204.2 to rotate in the opposite direction.

[0042] Refer to Figures 1 - 7In this embodiment, the first decompression transmission assembly includes two first toggle blocks 203.1 arranged on the outer peripheral side of the eccentric wheel 302.1. Further, the first elastic extrusion member 201 includes a first extrusion column 201.1 and a first mounting block 201.2 arranged at the bottom of the first extrusion column 201.1. The first mounting block 201.2 is provided with a first roller 201.3 that cooperates with the first toggle block 203.1 to drive the first extrusion column 201.1 to approach or move away from the flexible water inlet pipe 102. The outer peripheral side of the first extrusion column 201.1 is sleeved with a first return spring 201.4. Further, the second elastic extrusion member 202 includes a second extrusion column 202.1 and a second mounting block 202.2 arranged at the bottom of the second extrusion column 202.1. The second mounting block 202.2 is provided with a second roller 202.3. The driven wheel 204.2 is provided with a second roller 202.3 that acts on the second roller 202.3 to make the second extrusion column 202.1 approach or move away from the flexible water inlet pipe 102. The second toggle block 204.3 of the flexible water outlet pipe 103, the outer peripheral side of the second extrusion column 202.1 is sleeved with a second return spring 202.4, when the driving end of the driving source 301 rotates, the driving wheel 204.1 drives the driven wheel 204.2 to rotate in the opposite direction, thereby realizing a two-way transmission of power. When the first toggle block 203.1 on the outer peripheral side of the eccentric wheel 302.1 contacts the first roller 201.3 and drives the first extrusion column 201.1 away from the flexible water inlet pipe 102, the second toggle block 203.1 on the outer peripheral side of the eccentric wheel 302.1 contacts the first roller 201.3 and drives the first extrusion column 201.1 away from the flexible water inlet pipe 102, the second The moving block 204.3 will not contact the second roller 202.3, thereby achieving the goal of releasing the squeezing of the flexible water inlet pipe without releasing the squeezing of the flexible water outlet pipe. When the second moving block 204.3 on the driven wheel 204.2 contacts the second roller 202.3 and drives the second squeezing column 202.1 away from the flexible water inlet pipe 102, the first moving block 203.1 will not contact the first roller 201.3, thereby achieving the goal of releasing the squeezing of the flexible water outlet pipe without releasing the squeezing of the flexible water inlet pipe.

Specifically, the design of the extrusion block enables the first elastic extrusion member 201 and the second elastic extrusion member 202 to have a larger contact area when extruding the flexible pipe. This large-area contact can better fit the pipe surface and make the pressure more evenly distributed on the flexible pipe, which helps to avoid pipe damage caused by excessive local pressure and ensures that the pipe can be smoothly closed or opened when squeezed.
