Description

Technical Field

[0001] The utility model relates to a water pump, in particular to a water pump for a barreled water extractor. Background Art

[0002] In daily life, the water extractors for barreled water are more and more widely used. Most of them are directly installed on the top of the barreled water for use. This makes the water inlet of the water extractor located below and the water outlet located above. The whole flow channel has to flow from bottom to top. However, for the existing water pumps, the water inlets and outlets on the pump body are both located at one end of the pump body, and their inlet and outlet structures are not reasonably designed. This leads to the need to cooperate with other auxiliary structures to change the direction of the flow channel when the water pump is installed in the water extractor, or to bend the internal hose, increasing the structural cost of the water extractor and its overall volume, and greatly limiting the application scenarios of the water pump. Content of the Utility Model

[0040] Refer to Figure 1-7 As shown, a water pump for a barreled water pump includes a motor 10 for providing power and a pump body connected to the motor 10. The pump body includes:

[0041] An upper cover 1, and a water inlet pipe 11 is provided at the top of the upper cover 1;

[0042] A middle cover 3, a water outlet pipe 31 is provided on the side of the middle cover 3, and the opening direction of the water outlet pipe 31 is opposite to the opening direction of the water inlet pipe 11. The middle cover 3 and the upper cover 1 cooperate to form a water inlet flow channel and a water outlet flow channel. By grooving on their joint surfaces, it is avoided that it is difficult to process due to the internal cavity space during processing. A first valve plate 4 is provided on the water inlet flow channel, and a second valve plate 2 is provided on the water outlet flow channel. Both the first valve plate 4 and the second valve plate 2 are made of flexible materials to play a one-way conduction role;

[0043] A cylinder block 6 is provided below the middle cover 3, and a leather cup 5 is also clamped between the cylinder block 6 and the middle cover 3. The cylinder block 6 presses the leather cup 5 against the lower end surface of the middle cover 3. One end of the leather cup 5 away from the middle cover 3 passes through the cylinder block 6 and is connected to the swing frame 7;

[0044] The bottom cover 9 has its lower end surface fixed to the motor 10. The bottom cover 9 is connected to the bottom of the cylinder block 6 to form a cavity. The swing frame 7 is disposed in the cavity, and an eccentric seat 8 is connected to the bottom of the swing frame 7. The eccentric seat 8 is also connected to the rotating shaft on the motor 10. The motor 10 drives the eccentric seat 8 to rotate, causing the swing frame 7 to swing, thereby deforming the leather cup 5, and pushing the water flow to flow through the volume change.

[0045] Specifically, the structures of the water inlet channel and the water outlet channel are as follows: a first groove 12 and a second groove 13 are provided on the lower end surface of the upper cover 1. The first groove 12 communicates with the water inlet pipe 11. A third groove 32 is provided on the upper end surface of the middle cover 3, which cooperates with the first groove 12 to form the water inlet channel. A fourth groove 33 communicating with the water outlet pipe 31 is also provided on the upper end surface of the middle cover 3, which cooperates with the second groove 13 to form the water outlet channel.

[0046] Five first water passing openings 34 are evenly distributed in a circumferential array on the third groove 32. The first valve plate 4 is disposed on the side of the first water passing opening 34 close to the cylinder block 6. Five second water passing openings 35 are evenly distributed in a circumferential array on the fourth groove 33. The second valve plate 2 is disposed on the side of the second water passing opening 35 close to the upper cover 1, and the second valve plate 2 covers all five second water passing openings 35 at the same time.

[0047] Five water passing grooves 36 are further provided on the lower end surface of the middle cover 3. The water passing grooves 36 communicate the adjacent first water passing openings 34 and second water passing openings 35.

[0048] Normally, three groups of water passing openings are usually provided between the water inlet channel and the water outlet channel of the water pump. By setting five water passing openings, the communication area between the water inlet channel and the water outlet channel can be made larger without increasing the volume of the water pump, and the arrangement is more compact, the water pumping is more coherent, and a larger water flow can be supported to pass through.

[0049] Specifically, five movable cylinders are provided on the leather cup 5. The movable cylinders cooperate with the water passing grooves 36 to form a water absorption cavity whose volume changes under the drive of the motor 10. Increasing the number of movable cylinders is beneficial to improving the water flow of the water pump, and the water pumping is also more coherent.

[0050] Specifically, in the assembly manner of the upper cover 1, the middle cover 3 and the cylinder block 6, bolt holes are provided on the upper cover 1, the middle cover 3 and the cylinder block 6. Bolts pass through the three to lock them to the bottom cover 9. The assembly is simple and the structure is reliable.

[0051] Specifically, to improve the structural strength of the assembly, five positioning columns 61 are provided on the upper end surface of the cylinder block 6. Five avoidance grooves 37 cooperating with the positioning columns 61 are provided on the lower end surface of the middle cover 3. And notches cooperating with the positioning columns 61 are also provided on the leather cup 5, so that relative rotation between the cylinder block 6 and the middle cover 3 will not occur.

[0052] Specifically, to prevent misalignment during assembly, two anti-fooling posts 62 are provided on the upper end face of the cylinder block 6, and two anti-fooling holes that cooperate with the anti-fooling posts 62 are provided on the lower end face of the middle cover 3. During assembly, the two anti-fooling posts are inserted into the anti-fooling holes. Since the two anti-fooling posts are not arranged symmetrically, the assembly position is unique when the middle cover 3 is matched with the cylinder block, and it cannot be normally installed when misaligned.

[0053] Specifically, to improve the tight fit between the upper cover 1 and the middle cover 3 and prevent water leakage, the upper cover 1 and the middle cover 3 are bonded with glue.

[0054] Specifically, to facilitate the installation of the water pump, two installation parts 91 are provided on the side of the bottom cover 9, and openings are provided on the installation parts 91, and the water pump can be fixed by bolts.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
