Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1 and fig. 2 together, a description will now be given of a water leakage preventing pump according to an embodiment of the present application. This leak protection water pump includes piston assembly 1, inside hollow water pump main part 2 and installs in water pump main part 2 and with the pipeline 3 of water pump main part 2 rigid coupling, piston assembly 1 and pipeline 3 sliding connection just take place to remove along the axial extending direction of pipeline 3.

Among the above-mentioned technical scheme, 2 internal connection of water pump main part has pipeline 3, installs piston assembly 1 behind pipeline 3, starts the water pump, and piston assembly 1 constantly takes place to remove along the axial extending direction of pipeline 3. Because the pipe 3 connected with the water pump body 2 has no demoulding angle and has higher finish, when the piston assembly 1 moves in the pipe 3, the friction generated between the piston assembly 1 and the pipe 3 is smaller, and the abrasion generated on the piston assembly 1 is smaller. In the prior art, the piston assembly 1 is directly installed inside the water pump body 2, so that the piston assembly 1 directly contacts with the inner wall of the water pump body 2 when moving. Compared with the prior art, this application sets up pipeline 3 in 2 inside water pump main parts, makes piston assembly 1 remove in pipeline 3, when having reduced piston assembly 1 operation, because of the wearing and tearing to piston assembly 1 production with the friction of pipeline 3 to cause because the serious and then messenger's water pump of piston assembly 1 wearing and tearing leak, improved the waterproof performance and the life of water pump. In one example, the tube 3 is made of stainless steel, which results in a smoother finish of the inner wall of the tube 3, reducing the friction between the tube 3 and the piston assembly 1 as it slides within the tube 3.

In another embodiment of the present application, referring to fig. 2, the water pump body 2 includes a water inlet 21 and a driving member insertion opening 22, which are oppositely disposed, and a driving member (not shown) for driving the piston assembly 1 to move relative to the water pump body 2 is connected to an end of the piston assembly 1 close to the driving member insertion opening 22. After the driving part is started, the piston assembly 1 is driven by the driving part to perform linear motion back and forth along the pipeline 3 continuously, so that water flow continuously enters the water pump from the water inlet 21 under the action of the driving part and the water pump. The arrangement structure is simple, and the driving piece can drive the piston assembly 1 conveniently.

In another embodiment of the present application, referring to fig. 1, the water pump main body 2 is further provided with a water outlet 23, and the water outlet 23 is located between the water inlet 21 and the driving member insertion opening 22. When water flow enters the water pump main body 2 from the water inlet 21, the water flow directly flows to the water outlet 23 and does not need to pass through the driving piece inserting opening 22, the probability that the water flow flows to the driving piece inserting opening 22 is reduced, the water flow enters the driving piece inserting opening 22 and has adverse effects on the driving piece and other electronic components arranged at the driving piece inserting opening 22, and the waterproof performance of the water pump is improved.

In another embodiment of the present application, referring to fig. 2, the insertion opening 22 of the driving member is located on an axial end surface of the pipe 3, and the water outlet 23 is located on a circumferential surface of the pipe 3. Because the piston assembly 1 only moves in the pipeline 3, the water flow communicated with the water outlet 23 caused by the piston assembly 1 crossing the position of the water outlet 23 in the operation process is prevented from entering the driving piece inserting opening 22 from the water outlet 23, so that the driving piece and other electronic components arranged at the driving piece inserting opening 22 are influenced, and the waterproof performance of the water pump is further improved.

In another embodiment of the present application, please refer to fig. 2, the water inlet 21 is provided with a first check valve, and the water outlet 23 is provided with a second check valve. When water needs to be pumped, the first one-way valve is opened, and the second one-way valve is closed; when water pumping is not needed, the first one-way valve is closed, and the second one-way valve is opened. Thus, the flow direction of the water flow in the water pump main body 2 is ensured.

In another embodiment of the present application, referring to fig. 2, the piston assembly 1 is connected to a driving member (not shown) via a connecting member 4. When the water pump runs, the connecting assembly 4 continuously runs under the driving of the driving piece, and at the moment, the piston assembly 1 connected with the connecting assembly 4 also continuously runs along with the connecting assembly 4. So, link together piston assembly 1 and driving piece through coupling assembling 4, realized the slip of piston assembly 1, simple structure easily realizes.

In another embodiment of the present application, referring to fig. 2, the connecting component 4 is a link-slider mechanism. In particular, the connecting rod-slider mechanism may be a crank-slider mechanism. When the driving piece drives the crank block mechanism to operate, the crank block mechanism converts the rotation mode of the driving machine into the movement mode of the piston assembly 1, so that the piston assembly 1 is driven to slide conveniently, the sliding range of the piston assembly 1 is limited, and the compactness between the structures is enhanced. In some possible embodiments, the above-mentioned connecting assembly 4 may also be a lead screw, a rack and pinion mechanism, or the like; alternatively, the drive member may be a linear motor and the coupling assembly 4 may be used only to couple the output of the linear motor to the piston assembly 1.

In another embodiment of the present application, referring to fig. 2, the outer wall of the pipe 3 is provided with an annular groove 31 circumferentially surrounding the outer wall of the pipe 3. So, the axial joint strength when having strengthened pipeline 3 and water pump main part 2 and being connected has prolonged the life of water pump.

In another embodiment of the present application, referring to fig. 1, a water pump body 2 is injection molded onto a pipe 3. Hardness between water pump main part 2 and the pipeline 3 has not only been improved like this, still make in the water pump main part 2 supply the gliding passageway of piston assembly 1, the internal diameter at the pipeline 3 both ends of installing in water pump main part 2 promptly is unanimous, guaranteed the smooth and easy nature of piston assembly 1 when sliding along pipeline 3, reduced piston assembly 1 because of with the pipeline 3 friction and to the wearing and tearing that self caused, prolonged piston assembly 1's life, improved the waterproof performance of water pump.

In addition, this application embodiment still provides a towards tooth ware, including body and foretell leak protection water pump, leak protection water pump installs in the body. The specific structure of the anti-leakage water pump of the tooth flusher refers to the above embodiments, and as the tooth flusher adopts all the technical schemes of all the embodiments, the tooth flusher at least has all the beneficial effects brought by the technical schemes of the embodiments, and the detailed description is omitted here.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
