Description

Technical Field

[0001] This patent belongs to the field of water pump technology, and specifically refers to a water outlet pipe and a water pump. Background Art

[0002] Existing water pumps are equipped with an outlet pipe for allowing water to flow outwards. The outlet pipe is generally equipped with a water flow switch and a check valve for preventing water from flowing back. The check piece in the check valve is generally blocked on the water inlet of the outlet pipe, and the check piece abuts against the wall surface of the outer edge of the water inlet. At this time, if there are impurities in the water flow, the impurities may be pressed between the check piece and the wall surface of the outer edge of the water inlet, resulting in the check piece being unable to abut tightly against the wall surface of the outer edge of the water inlet, thereby affecting the sealing check effect of the check piece. Summary of the invention

[0003] The purpose of this patent is to provide a water outlet pipe of a water pump that effectively improves the check sealing effect.

[0004] The purpose of this patent is achieved in this way:

[0005] A water outlet pipe of a water pump, comprising:

[0006] A pipeline body, wherein the pipeline body is provided with a water inlet for connecting to a water pump and a water outlet for connecting to the outside, a chip removal groove is provided on the outer edge of the water inlet, and a support platform is provided between the chip removal groove and the water inlet; and

[0007] A check piece is slidably arranged in the pipeline body; the check piece is connected to a reset piece, and the reset piece is used to give the check piece a tendency to abut against the abutting platform and make the check piece seal on the water inlet.

[0008] Furthermore, the chip removal groove has an arc-shaped connecting surface connected to the abutting platform.

[0009] Furthermore, the return stopper includes a slide bar and a pressure plate connected to one end of the slide bar, and when the pressure plate abuts against the abutment platform, the chip removal groove surrounds the outside of the pressure plate.

[0010] Furthermore, an annular supporting boss is provided on the abutting platform, and the supporting boss is arranged on the inner edge of the abutting platform close to the water inlet, and is used to abut against the check member.

[0011] Furthermore, the pipeline body is also provided with a pressure stabilizing port, through which a pressure tank is connected.

[0012] Furthermore, a support frame fixed on the pressure stabilizing port is provided in the pipeline body, a mounting seat connected to the check piece is provided on the mounting frame, and a gap portion connecting the pipeline body and the pressure tank is provided on the outer edge of the mounting seat.

[0013] Furthermore, the support frame includes an outer ring member, which is provided with a plurality of connecting arms in sequence, and is connected to the mounting seat fixed at the center of the outer ring member through the connecting arms.

[0014] Furthermore, the pipeline body includes a pipe seat and a cover body fixed on the pipe seat, and the support frame is integrally formed in the cover body.

[0015] A water pump comprises the above-mentioned water outlet pipe, and also comprises a fluid pump casing and a motor pump casing, wherein the water outlet pipe is fixed on the fluid pump casing.

[0016] Compared with the prior art, the outstanding and beneficial technical effects of this patent are:

[0017] A chip groove is also provided on the outer edge of the abutment platform in the present patent. When the check member moves downward, impurities between the pressure plate and the abutment platform will be pushed into the chip groove due to the water flow movement formed by the downward movement of the check member, and since the chip groove has an arc-shaped connecting surface connected to the abutment platform, the arc-shaped connecting surface can guide the impurities to fall into the chip groove, thereby reducing the residual amount of impurities; in addition, since the chip groove is lower than the abutment platform, the impurities discharged into the chip groove will basically not affect the abutment between the abutment platform and the check member, thereby effectively preventing the impurities from affecting the check effect of the check member; after the water pump starts working again, the impurities in the chip groove will be discharged from the water outlet under the action of the water flow.

[0030] The present invention is further described below in conjunction with specific embodiments:

[0031] A water outlet pipe of a water pump pipeline is used in a water pump, such as Figure 1 As shown, the water pump includes a fluid pump housing 5, in which a chamber for fluid medium to pass is provided, the upper side of the fluid pump housing 5 is connected to the water outlet pipe described in this patent, and a motor housing 6 is fixed to the side of the fluid pump housing 5.

[0032] like Figure 2 , 3 As shown in Figures 5 and 6, the water outlet pipe includes a pipe body 1 and a check member 3, and is provided with a water inlet 11 for connecting to a water pump, and a water outlet 12 for connecting to the outside world; the water inlet 11 is arranged at the lower end of the pipe body 1, and corresponding threaded joints are arranged on the water inlet 11 and the fluid pump housing 5, and the entire pipe body 1 is fixed to the fluid pump housing 5 through the threaded joints. The pipe body is cylindrical as a whole, and the water outlet 12 is arranged on its outer wall, and the water outlet 12 is used to connect to an external pipe, so that the water in the fluid pump housing 5 passes through the pipe body 1 and then flows out from the water outlet 12.

[0033] The check member 3 can be slidably arranged in the pipeline body 1. Figure 3 , 5 As shown, in this patent, the check member 3 includes a sliding rod 32 and a pressure plate 33 connected to one end of the sliding rod 32, and its overall cross-section is in a "T" shape. The check member 3 is connected to a reset member 31, and the reset member 31 is used to give the check member 3 a tendency to abut against the abutment platform 21 and seal the check member 3 on the water inlet 11; the reset member 31 is specifically a set of springs arranged on the sliding rod 32, the lower end of the spring abuts against the end face of the pressure plate 33, and the upper end of the spring abuts against the pipeline body 1 to move the entire check member 3 downward, so that the pressure plate 33 is blocked on the water outlet 12.

[0034] In fact, the pipeline body 1 in this patent includes a cylindrical pipe seat 14, the water inlet 11 and the water outlet 12 are formed on the lower end and the outer wall of the pipe seat 14, and the upper end of the pipe seat 14 is formed with an opening, and a cover 15 connected to the pipe seat 14 is fixed in the opening. Figure 5 , 6 As shown, the lower end of the cover body 15 is integrally formed with a support frame 16, which includes an outer ring member 161, and a plurality of strip-shaped connecting arms 162 are sequentially arranged in the outer ring member 161, and a mounting seat 163 fixed at the center of the outer ring member 161 is connected through the connecting arms 162. A through hole is provided in the mounting seat 163, which is used for the slide bar 32 to pass through. At this time, the two ends of the reset member 31 are respectively against the mounting seat 163 and the pressure plate 33. When the reset member 31 drives the check member 3 to move, the slide bar 32 on the check member 3 moves through the mounting seat 163, and is guided by the mounting seat 163. The outer edge of the mounting seat 163 is provided with a threaded structure, and correspondingly, a corresponding threaded structure is provided at the opening of the tube seat 14, and the cover body 15 can be connected to the tube seat 14 through the threaded structure.

[0035] Furthermore, a chip removal groove 2 is provided at the outer edge of the water inlet 11, and a support platform 21 is provided between the chip removal groove 2 and the water inlet 11. Figure 3 , 7 The water inlet 11 in this patent is circular, and a horizontal abutment platform 21 is provided on the outer edge of the water inlet 11, and a chip groove 2 lower than the abutment platform 21 is provided on the outer edge of the abutment platform 21. The bottom of the chip groove 2 is flat, and arc-shaped connecting surfaces 22 for connecting the abutment platform 21 and the outer wall of the tube seat 14 are provided on both sides of the bottom surface.

[0036] When the water pump described in this patent is working, the impeller in the fluid pump housing 5 rotates to drive the water flow toward the water inlet 11, and the water flow will lift the check member 3, so that the water inlet 11 is opened to discharge water; when the water pump stops working, the check member 3 will move downward under the action of the reset member 31, so that the pressure plate 33 rests on the abutment platform 21 on the outer edge of the water inlet 11 to prevent return. Since the outer edge of the abutting platform 21 in the present invention is also provided with a chip groove 2, when the check member 3 moves downward, the impurities between the pressure plate 33 and the abutting platform 21 will be pushed into the chip groove 2 due to the water flow movement formed by the downward movement of the check member 3, and since the chip groove 2 has an arc-shaped connecting surface 22 connected to the abutting platform 21, the arc-shaped connecting surface 22 can guide the impurities to fall into the chip groove 2, thereby reducing the residual amount of impurities; in addition, since the chip groove 2 is lower than the abutting platform 21, the impurities discharged into the chip groove 2 will basically not affect the abutment between the abutting platform 21 and the check member 3, thereby effectively preventing the impurities from affecting the sealing check effect of the check member 3; after the water pump resumes operation, the impurities in the chip groove 2 will be discharged from the water outlet 12 under the action of the water flow. In summary, the present invention effectively reduces the influence of impurity blockage on the operation of the check member 3 by setting the chip groove 2, thereby increasing the check effect of the water outlet pipe.

[0037] Furthermore, the abutting platform 21 is also provided with an annular supporting boss 211, such as Figure 3 , 4 As shown, the support boss 211 is arranged on the inner edge of the abutting platform 21 close to the water inlet 11, and is used to abut against the check piece 3, which can reduce the contact surface between the check piece 3 and the pipeline body 1, thereby reducing the probability of impurities clogging the check piece 3, thereby increasing the check effect of the water outlet pipe.

[0038] Furthermore, the pipeline body 1 is also provided with a pressure stabilizing port 13, through which the pressure tank 4 is connected. Figure 2 , 3 As shown, the pressure-stabilizing port 13 is located at the upper end of the pipeline body 1, that is, located on the cover body 15; the pressure-stabilizing port 13 and the pressure tank 4 are provided with corresponding threaded structures, and the pressure tank 4 is connected to the pressure-stabilizing port 13 through the threaded structure. Since the support frame 16 is located at the center of the cover body 15, this patent forms a gap portion 164 on the outer edge of the support frame 16 that is opposite to the pressure-stabilizing port 13 by reducing the size of the support frame 16. The pressure tank 4 can be connected to the pipeline body 1 through the gap portion 164, so that the pressure tank 4 can work normally. In summary, the water outlet pipe in this patent realizes the check function while stabilizing the pressure in the water pump by adding the pressure tank 4, realizing the water pump pressure stabilization, and improving the working performance of the water pump.

[0039] The above embodiments are only preferred embodiments of this patent and are not intended to limit the protection scope of this patent. Therefore, any equivalent changes made based on the structure, shape, and principle of this patent should be covered within the protection scope of this patent.
