Description

Technical Field

[0001] This utility model relates to the field of water pump technology, specifically a drinking water delivery pump. Background Technology

[0002] A drinking water delivery pump is a device specifically designed for pumping drinking water. The water source connection pipe and the water source discharge pipe are installed at the ends of the connection pipes on both sides of the drinking water delivery pump. The water source will pass through the water source connection pipe into the pump and then be discharged from the water source discharge pipe, thus providing clean drinking water.

[0003] Existing drinking water pumps have the problem of being subjected to high water pressure at pipe connections and being prone to squeezing out impurities on both sides.

[0004] The reason for this problem is that the installation pipe is usually inserted into the connecting pipe on one side, and then the outer ring of the pipe is connected and fixed with screws. To improve the connection effect between the two sets of pipes, a rubber sealing ring is set inside the connecting pipe. However, the length of the sealing ring is less than the length of the installation pipe inserted. Therefore, after the installation pipe is inserted into the connecting pipe, the gap between the end of the installation pipe and the connecting pipe is relatively large. The end of the installation pipe also has a certain thickness. Therefore, when the water flow is rapid, it will impact the end of the installation pipe, causing some impurities to accumulate on the outer side of the end of the installation pipe and the position of the connecting pipe under the impact force. This may lead to the possibility of impurities being flushed out all at once during long-term use. In addition, the rapid water flow for a long time will also cause a certain impact force on the connection of the installation pipe, thus affecting the connection effect between the installation pipe and the connecting pipe. Therefore, we propose a drinking water delivery pump. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model proposes a drinking water pump, which solves the problems of the existing drinking water pumps having large water pressure impact at the pipe connection and the easy squeezing of impurities on both sides.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows: a drinking water pump, including a pump body, a connecting pipe provided on the outside of the pump body, an installation pipe provided on the outside of the connecting pipe, a connecting mechanism provided inside the connecting pipe, the connecting mechanism including an arc-shaped pipe installed inside the connecting pipe, the arc-shaped pipe being used to reduce pipe connection gaps, an installation box installed inside the connecting pipe, the arc-shaped pipe being movably disposed outside the installation box, a spring installed outside the arc-shaped pipe, the spring being disposed inside the installation box, the spring being used to reduce the impact force of water flow on the arc-shaped pipe.

[0007] Preferably, the mounting tube is fixedly connected to the outside of the mounting tube, the insertion tube is movably inserted into the inside of the connecting tube, and the insertion tube is disposed on the outside of the arc-shaped tube.

[0008] Preferably, a connecting rubber ring is sleeved on the outside of the arc-shaped tube, the insertion tube is movably sleeved on the outside of the connecting rubber ring, and a protective rubber ring is sleeved on the arc-shaped tube away from the connecting rubber ring, the protective rubber ring being slidably connected inside the connecting tube.

[0009] Preferably, an auxiliary plate is fixedly connected to the outside of the connecting rubber ring, and the auxiliary plate is slidably disposed inside the mounting box.

[0010] Preferably, a baffle is fixedly connected to the inner side of the mounting box, the auxiliary plate is slidably connected to the inner side of the baffle, and a movable plate is fixedly connected to the outer side of the auxiliary plate, the movable plate being movably disposed inside the mounting box.

[0011] Preferably, a limiting rod is fixedly connected inside the mounting box, the movable plate is movably sleeved on the outside of the limiting rod, the spring is movably sleeved on the outside of the limiting rod, and the two ends of the spring are respectively fixed inside the mounting box and outside the movable plate.

[0012] The beneficial effects of this utility model are:

[0013] The technical solution of this utility model involves inserting a connector into the inside of a connecting pipe. The connector then fits around the outside of the connecting ring and the outside of the arc-shaped pipe. During the water flow impact, the connector passes through the inner side of the arc-shaped pipe. The arc shape of the inner side of the arc-shaped pipe reduces the impact force of the water flow. The end of the arc-shaped pipe reduces the contact area between the water flow and the end of the connector. At this time, the auxiliary plate also moves the movable plate inside the mounting box, thereby mitigating the impact force of the water flow by the springs on both sides of the movable plate. This increases the effectiveness of the arc-shaped pipe. By setting the arc-shaped pipe to protect the connection, the impact force of the water flow is reduced, and the contact area between the connection and the water flow is reduced, thus reducing the accumulation of impurities. Furthermore, the springs reduce the impact force of the water flow, increasing the effectiveness of the arc-shaped pipe and improving the stability and performance of the connection positions on both sides of the water pump body.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] This application provides a drinking water pump, which solves the problems of existing drinking water pumps having large water pressure impacts at pipe connections and the easy squeezing of impurities on both sides.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] According to the appendix Figure 1-4 As shown, the pump includes a water pump body 1, a connecting pipe 101 on the outside of the water pump body 1, an installation pipe 102 on the outside of the connecting pipe 101, and a connecting mechanism inside the connecting pipe 101. The connecting mechanism includes an arc-shaped pipe 2 installed inside the connecting pipe 101. The arc-shaped pipe 2 is used to reduce pipe connection gaps. An installation box 202 is installed inside the connecting pipe 101. The arc-shaped pipe 2 is movably disposed outside the installation box 202. A spring 203 is installed outside the arc-shaped pipe 2 and disposed inside the installation box 202. The spring 203 is used to reduce the impact force of water flow on the arc-shaped pipe 2.

[0024] The external fixed connection of the mounting tube 102 is a plug tube 209, which is movably inserted into the inside of the connecting tube 101. The plug tube 209 is located outside the arc-shaped tube 2. A connecting rubber ring 201 is sleeved on the outside of the arc-shaped tube 2. The plug tube 209 is movably sleeved on the outside of the connecting rubber ring 201. A protective rubber ring 206 is sleeved on the arc-shaped tube 2 at a position away from the connecting rubber ring 201. The protective rubber ring 206 is slidably connected inside the connecting tube 101.

[0025] An auxiliary plate 205 is fixedly connected to the outside of the connecting rubber ring 201. The auxiliary plate 205 is slidably disposed inside the mounting box 202. A baffle 207 is fixedly connected to the inside of the mounting box 202. The auxiliary plate 205 is slidably connected to the inside of the baffle 207. A movable plate 204 is fixedly connected to the outside of the auxiliary plate 205. The movable plate 204 is movably disposed inside the mounting box 202. A limit rod 208 is fixedly connected inside the mounting box 202. The movable plate 204 is movably sleeved on the outside of the limit rod 208. A spring 203 is movably sleeved on the outside of the limit rod 208. The two ends of the spring 203 are fixed inside the mounting box 202 and outside the movable plate 204, respectively.

[0026] By inserting the connector 209 into the connecting pipe 101, the connector 209 will be fitted onto the outside of the connecting rubber ring 201, and simultaneously positioned outside the arc-shaped pipe 2. Then, screws are installed inside the fixing ring plate of the connecting pipe 101 and the mounting pipe 102. During water flow impact, the screws will pass through the inner side of the arc-shaped pipe 2. Both ends of the arc-shaped pipe 2 are in contact with the inner sides of the connector 209 and the connecting pipe 101. The arc shape of the inner side of the arc-shaped pipe 2 reduces the impact force of the water flow, and the arc-shaped ends of the pipe 2 reduce the contact area between the water flow and the ends of the connector 209, thereby reducing the impact force of the water flow on the connection. Furthermore, to prevent the accumulation of impurities, and when the arc-shaped pipe 2 is subjected to the impact force of water flow, the impact force will drive the arc-shaped pipe 2 to move. At this time, the auxiliary plate 205 will move to the inner side of the center of the mounting box 202, and the auxiliary plate 205 will also move to the inner side of the baffle 207. The baffle 207 shields and protects the interior of the mounting box 202, so that the auxiliary plate 205 will not affect the internal structure of the mounting box 202 during movement. The auxiliary plate 205 will also drive the movable plate 204 to move inside the mounting box 202, thereby mitigating the impact force of the water flow by the springs 203 on both sides of the movable plate 204, thus increasing the effectiveness of the arc-shaped pipe 2.

[0027] In summary, compared with existing technologies, it has the following beneficial effects:

[0028] By inserting the connector 209 into the connecting pipe 101, the connector 209 will fit over the outside of the connecting ring 201 and the outside of the arc-shaped pipe 2. During the water flow impact, it will pass through the inner side of the arc-shaped pipe 2. The arc shape of the inner side of the arc-shaped pipe 2 can reduce the impact force of the water flow. The end of the arc-shaped pipe 2 can reduce the contact area between the water flow and the end of the connector 209. At this time, the auxiliary plate 205 will also drive the movable plate 204 to move inside the mounting box 202. The impact force of the water flow is relieved by the springs 203 on both sides of the movable plate 204, thereby increasing the effectiveness of the arc-shaped pipe 2. By setting the arc-shaped pipe 2 to protect the connection, the impact force of the water flow is reduced, and the contact area between the connection and the water flow is reduced, the accumulation of impurities is reduced. The springs 203 reduce the impact force of the water flow, increasing the effectiveness of the arc-shaped pipe 2. At the same time, the stability and effectiveness of the connection positions on both sides of the water pump body 1 are increased.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
