Description

Technical Field

[0001] The present invention belongs to the technical field of peristaltic pumps, and in particular relates to a modular peristaltic pump. Background Art

[0002] The washing machine uses fuzzy weighing technology to sense the weight of clothes, and combines the washing program and the ambient temperature determined by the temperature sensor to intelligently control the operation of the peristaltic pump. When the peristaltic pump is working, the motor drives the rotor and sleeve to rotate, and the sleeve squeezes the rubber tube or peristaltic tube to form a partial vacuum in the tube, thereby drawing the detergent out of the detergent box and pumping it to the multi-way distributor through the conduit, and finally to the inner barrel of the washing machine.

[0003] The pump body of an existing peristaltic pump is generally assembled together by an upper pump shell and a lower pump shell for use. When the upper pump shell and the lower pump shell are installed together for use, they are generally installed with screws. This installation and disassembly method is relatively inconvenient. In addition, the sealing performance of the upper pump shell when connected to the motor module is poor, which will cause dust to enter the motor module. Dust entering the motor will affect the internal parts of the motor. At the same time, the existing peristaltic pump is not convenient for composing different angles of motor and pump body modules, and the scope of application is limited. In view of this, we propose a modular peristaltic pump. Summary of the Invention

[0004] The object of the present invention is to provide a modular peristaltic pump to solve the problems raised in the above background technology.

[0009] The limiting components are located on the lower shell of the pump body and are used to limit the two limiting plug plates.

[0010] In this technical solution, through the cooperation between the first sealing ring, the extrusion ring, the limiting ring, the second sealing ring and the fixing assembly, the sealing between the annular frame and the upper shell of the pump body is ensured to be strong, dust is prevented from entering the annular frame and the protective shell, and the dust is prevented from affecting the operation of the synchronous motor. Through the cooperation between the four limiting plug plates, the four U-shaped plates and the limiting assembly, when installing the upper shell and the lower shell of the pump body, there is no need to use screws for fixed installation, making disassembly more convenient and quick.

At this time, the first sealing ring and one end of the annular frame will be located in the extrusion ring. Under the action of the thread, the staff can use a hexagonal wrench to install the hexagonal bolt into the connecting plate one and continue to rotate the hexagonal bolt so that one end of the hexagonal bolt is threadedly installed into the connecting plate two.

At this time, the limiting ring 19 will contact the first sealing ring 13, and the staff can push the extrusion ring 20 so that the extrusion ring 20 is set on the limiting ring 19, and the second sealing ring 21 in the extrusion ring 20 will It will be in close contact with the limiting ring 19. At this time, one end of the first sealing ring 13 and the annular frame 15 will be located in the extrusion ring 20. Under the action of the thread, the staff can use a hexagonal wrench to install the hexagonal bolt 18 into the connecting plate 1 8 and continue to rotate the hexagonal bolt 18 so that one end of the hexagonal bolt 18 is threadedly installed into the connecting plate 2 10. At this time, the extrusion ring 20 will slide on the pump body upper shell 3 and move toward the direction close to the annular frame 15. At this time, the second sealing ring 21 will be squeezed by the extrusion ring 20 and will be deformed, and the first sealing ring 13 will be squeezed by the limiting ring 19 and will also be deformed, ensuring a strong seal between the pump body upper shell 3 and the annular frame 15.

[0085] After that, the staff can arrange the rotating shaft sleeve on the pump body lower shell 4 on the shaft sleeve in the pump body upper shell 3, and then push the pump body lower shell 4 in the direction of the pump body upper shell 3, so that the inclined surface 25 on the limiting plug plate 5 contacts the U-shaped plate 7. At this time, the limiting plug plate 5 will be squeezed and deformed by the U-shaped plate 7, and one end of the limiting plug plate 5 will be bent in the direction close to the pump body lower shell 4 until the inclined surface 25 moves to the side of the U-shaped plate 7 away from the pump body upper shell 3. At this time, one end of the limiting plug plate 5 will return to its original shape, so that one end of the limiting plug plate 5 will hook the U-shaped plate 7. The four limiting plug plates 5 will simultaneously enter the corresponding U-shaped plates 7 and hook the corresponding U-shaped plates 7, thereby fixing the pump body upper shell 3 and the pump body lower shell 4. Rubber pads are installed on the opposite sides of the pump body upper shell 3 and the pump body lower shell 4. The two rubber pads will be deformed to ensure the sealing between the pump body upper shell 3 and the pump body lower shell 4.

[0086] In the initial state, the rectangular rod 22 is located in the L-shaped groove 24, and the baffle 26 is located in the slide groove 27. When in use, the staff can move the rectangular rod 22 in the direction away from the upper shell 3 of the pump body, and the rectangular rod 22 will slide in the L-shaped groove 24, and the baffle 26 will slide on the two guide rods 28. At this time, the two springs 29 will be squeezed and contracted. Then, the rectangular rod 22 can be moved upward, and the spring 29 on the rectangular rod 22 will slide upward in the limit groove 30, so that the rectangular rod 22 can move forward. The hand is inserted into the through groove 23, and then the hand is released. Under the action of the rebound force of the two springs 29, the spring 29 will drive the baffle 26 to move toward the direction of the pump body upper shell 3, so that one end of the baffle 26 extends to the outside, and one side of the baffle 26 will contact one side of the limit plug 5. At this time, the limit plug 5 will be located between the U-shaped plate 7 and the baffle 26. The baffle 26 will support the limit plug 5 to prevent the limit plug 5 from being deformed, thereby ensuring the stability of the fixation of the pump body upper shell 3 and the pump body lower shell 4.
