[0023] The following will provide a clear and complete description of the technical solutions in the present embodiment of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only preferred embodiments of the present invention.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] See attached Figures 1 to 4 In the embodiment of the utility model, a liquid lifting pump includes a tube body 10 and a pump body 20. The tube body 10 has a platform 11, a first sleeve 12, a second sleeve 13, and a curved pipe 14. The upper end of the first sleeve 12 is connected to the platform 11, the lower end of the first sleeve 12 is connected to the second sleeve 13, and the lower end of the second sleeve 13 is connected to the curved pipe 14. The curved pipe 14 is provided with a first one-way valve 15 at one end away from the second sleeve 13 to prevent liquid backflow;

[0027] The first sleeve 12, the second sleeve 13, and the curved pipe 14 are connected to form an inner cavity 101, the platform 11 is provided with a through hole corresponding to the inner cavity 101, and the pump body 20 is installed in the inner cavity 101; and the platform 11, the first sleeve 12, the second sleeve 13, and the curved pipe 14 are made of stainless steel.

[0028] Preferably, the outer surface of the tube body 10 is coated with a plastic layer, which can improve the texture of the tube body 10 and prevent the stainless steel from directly contacting liquid (usually hand soap). Compared with the tube body 10 made entirely of plastic, the hardness and rigidity are also better.

[0029] During actual manufacturing, a limiting ring 121 is provided on the upper end surface of the first sleeve 12. During connection, the first sleeve 12 passes through the through hole, and the limiting ring 121 is positioned on the upper side of the through hole. The limiting ring 121 is fixedly connected to the platform 11 through a riveting process.

[0030] In actual application, the lower end of the first sleeve 12 has a necking section 122, and the necking section 122 is welded to the second sleeve 13; the second sleeve 13 and the elbow 14 are connected by welding. It should be noted that during manufacturing, the necking section 122 can be realized in the following manner: a connector with an outer diameter equal to or slightly larger than the inner diameter of the first sleeve 12 is provided at the lower end of the first sleeve 12, and the connector is connected to the first sleeve 12 by a welding process, and the second sleeve 13 is also connected to the first sleeve 12 by a welding process, thereby realizing the main body manufacturing of the tube body 10. Of course, the necking section 122 can also be directly manufactured on the first sleeve 12 by other processes.

[0031] Furthermore, the pump body 20 includes a pump head 21, the pump head 21 is connected to a first pump tube 22 and a second pump tube 23, and the pump body 20 is also connected to an adjustment member 24 for adjusting the liquid output. The platform 11 is provided with a positioning groove 16 adapted to the second pump tube 23.

[0032] Typically, a second one-way valve 25 for preventing air from flowing back is disposed at one end of the first pump tube 22 away from the pump head 21. In practical applications, a return spring 26 is disposed between the pump body 20 and the lower end of the first sleeve 12.

[0033] The design focus of the utility model is that it mainly takes into account the production convenience and the hardness and durability of the product structure through the setting of the pump body; at the same time, the setting of the limit ring on the first sleeve also has the benefits of convenient assembly and processing, as well as many advantages such as stable connection.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
