DETAILED DESCRIPTION

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] like Figure 1-Figure 5 As shown, the water pump injection device comprises a water pump 1, which is provided with a water inlet 2, a filter chamber 40, an inner chamber 3, an impeller chamber 4 for accommodating an impeller, an outer chamber 5, a water outlet 6 and a drain port 7. The water inlet 2 is connected to the filter chamber 40, the inner chamber 3 is used to connect the filter chamber 40 and the impeller chamber 4, the impeller chamber 4 is connected to the outer chamber 5, the outer chamber 5 is connected to the water outlet 6 and the drain port 7, the inner chamber 3 is provided with an opening 8 connected to the outer chamber 5 and a first one-way valve 9 arranged at the opening 8, the water pump 1 is also provided with a first drainage channel 10 connected to the inner chamber 3 and a second drainage channel 11 connected to the outer chamber 5, the first drainage channel 10 and the second drainage channel 11 are both connected to the drain port 7, and a first sealing cover 12 for sealing the first drainage channel 10 and the second drainage channel 11 is arranged at the drain port 7, and the filter chamber 40, the inner chamber 3, the impeller chamber 4 and the outer chamber 5 are integrated.

[0025] To further elaborate, the second drainage channel 11 includes a fixed section 13 and a detachable section 14, and the fixed section 13 is detachably connected to the detachable section 14. The fixed section 13 is connected to the first drainage channel 10. When the detachable section 14 is connected to the fixed end, the detachable section 14 separates the first drainage channel 10 and the fixed section 13, and the two do not affect each other. When the detachable section 14 is removed, the fixed section 13 will be connected to the first drainage channel 10. This arrangement is used to ensure that during normal use, the liquid in the inner cavity 3 will not enter the outer cavity 5 through the first drainage channel 10 and the fixed section 13. Similarly, the liquid in the outer cavity 5 will not enter the inner cavity 3 through the first drainage channel 10 and the fixed section 13.

[0026] To elaborate further, the fixed section 13 is provided with a clearance groove 15 for inserting the detachable section 14, and the end of the detachable section 14 close to the clearance groove 15 is provided with a first installation groove 16 for installing a sealing ring. The provision of the clearance groove 15 facilitates the installation of the detachable section 14. At the same time, the provision of the first installation groove 16 for installing the sealing ring can increase the sealing performance and prevent the liquid in the fixed section 13 from leaking into the first drainage channel 10 from the gap.

[0027] To further explain, the first sealing cover 12 is threadedly connected to the first drainage channel 10, and the first sealing cover 12 is provided with a slot 17 for the removable section 14 to be inserted and fixed, and a connecting column 18 is provided in the slot 17 to be inserted into the removable section 14, and a second installation groove 19 for installing a sealing ring is provided at one end of the removable section 14 close to the slot 17. The first sealing cover 12 and the yield groove 15 can cooperate to fix the removable section 14 on the central axis of the first drainage channel 10, and the second installation groove 19 is provided to prevent the liquid in the first drainage channel 10 from entering the removable section 14. When the first sealing cover 12 is opened, both the first drainage channel 10 and the second drainage channel 11 are opened.

[0028] To elaborate further, a filter screen 20 for filtering the liquid entering the inner cavity 3 is provided at the place where the inner cavity 3 is connected to the first drainage channel 10. The filter screen 20 can filter the liquid entering the inner cavity 3, retain impurities, and discharge them through the first drainage channel 10, thereby reducing the impact of impurities on the water pump 1 and facilitating subsequent cleaning.

[0029] To elaborate further, a first receiving groove 21 for accommodating a first one-way valve 9 is provided at the opening 8. The first one-way valve 9 includes a spring 22, a limiting block 23 and a limiting column 24 for limiting the limiting block 23 from leaving the first receiving groove 21. One end of the spring 22 is connected to the bottom of the first receiving groove 21, and the other end of the spring 22 is connected to the limiting block 23. The spring 22 is used to prop up the limiting block 23 to open the opening 8. Under normal circumstances, the spring 22 will prop up the limiting block 23 so that the limiting block 23 no longer seals the opening 8. When the liquid in the outer cavity 5 wants to enter from the opening 8, it will first squeeze the spring 22 so that the limiting block 23 will seal the opening 8, thereby achieving the effect of a one-way valve.

[0030] In further detail, the limiting block 23 includes a closing block 25 and an extension block 26. The extension block 26 is arranged at the end of the closing block 25 away from the opening 8. The closing block 25 is provided with an extrusion groove 27 at the end close to the opening 8. By setting the extension block 26, the sealing performance of the closing block 25 can be increased, and the extension block 26 is adapted to the first accommodating groove 21.

[0031] In further detail, the outer cavity 5 is provided with a water outlet pipe 28 for communicating with the water outlet 6 , and the water outlet pipe 28 is provided with a second one-way valve 29 for preventing liquid reflux, which is used to prevent the liquid that has left the water outlet 6 from returning to the outer cavity 5 .

[0032] To elaborate further, a limiting channel 30 for installing a second one-way valve 29 is provided in the water outlet pipe 28, the limiting channel 30 includes a tapered section 31 and a limiting section 32, a support frame 33 is provided at the tapered end, the second one-way valve 29 includes a supporting rod 34 and a baffle 35, the support frame 33 is provided with a through hole for the supporting rod 34 to pass through, a limiting block 36 for limiting the descent of the supporting rod 34 is provided in the through hole, the supporting rod 34 is provided with a convex ring 37 cooperating with the limiting block 36, the baffle block 35 is provided with a second accommodating groove 38, when the liquid moves from the outer cavity 5 to the water outlet 6, the baffle block 35 will be lifted up, so that the baffle block 35 leaves the limiting section 32 and no longer seals the limiting section 32, when the liquid refluxes, the baffle block 35 will be moved downward, so that the baffle block 35 re-enters the limiting section 32, the limiting section 32 is sealed, and the liquid is prevented from flowing back.

[0033] To elaborate further, the water inlet 2 and the water outlet 6 are both threadedly connected with a second sealing cover. When not in use, the water inlet 2 and the water outlet 6 can be sealed by the second sealing cover to prevent external impurities from entering the water pump 1 and affecting the service life of the water pump 1.

[0034] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0035] Although a large number of terms are used in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
