Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a water pump buffer structure. Background Art

[0002] In conventional water pump designs, the water outlet chamber of the water pump usually adopts a straight-through structure, and the water flows directly out of the water pipe from the water outlet chamber. Although this design simplifies the structure and manufacturing process of the water pump to a certain extent, it also brings a series of problems. First, due to the rapid discharge of water, the fluid dynamics characteristics cause the water flow to produce a large flow rate at the outlet, which in turn causes significant vibration. This vibration not only affects the normal operation of the water pump, but may also damage other components of the equipment and shorten the service life of the water pump.

[0003] Secondly, high-velocity water will generate a lot of noise when it hits the outlet pipe. The noise problem not only affects the user experience, but may also cause interference to the surrounding environment, especially in places where low-noise operation is required, such as hospitals and libraries. This noise is mainly caused by the interaction between water flow and still air and the turbulence generated by water flow during the flow.

[0004] Therefore, it is necessary to further improve and perfect the prior art to overcome these deficiencies, and the present invention is made based on this situation. Utility Model Content

[0005] The utility model aims to overcome the deficiencies of the prior art and provide a water pump buffer structure with simple structure, low noise and good buffer effect.

[0006] The utility model is realized by the following technical solutions:

[0007] In order to solve the above technical problems, the utility model provides a water pump buffer structure, comprising a water inlet pipe, a water inlet chamber, a water outlet chamber and a water outlet pipe, a first one-way valve is arranged between the water inlet pipe and the water inlet chamber, a water pump driving device is arranged in the water inlet chamber, and a second one-way valve is arranged between the water inlet chamber and the water outlet chamber;

[0008] It also includes a buffer cavity, wherein the bottom of the buffer cavity is provided with a water inlet connected to the water outlet cavity, and the side of the buffer cavity is provided with a water outlet connected to the water outlet pipe;

[0009] The top of the buffer cavity is provided with an elastic buffer sheet, and the bottom surface of the buffer sheet is honeycomb-shaped and includes a plurality of buffer facets.

[0010] In order to further solve the technical problem to be solved by the utility model, in a water pump buffer structure provided by the utility model, the buffer surface is one or more of a convex surface, a flat surface and a concave surface.

[0011] In order to further solve the technical problem to be solved by the utility model, in a water pump buffer structure provided by the utility model, the bottom surface of the buffer sheet protrudes toward the inside of the buffer cavity.

[0012] In order to further solve the technical problem to be solved by the utility model, the utility model provides a water pump buffer structure, in which the top of the buffer cavity is provided with an opening, a top cover is installed at the opening, and the top cover is located above the buffer plate and presses the periphery of the buffer plate.

[0013] In order to further solve the technical problem to be solved by the utility model, in a water pump buffer structure provided by the utility model, a plurality of support columns are arranged on the top surface of the buffer sheet, and the support columns are also elastic.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] 1. In the utility model, an elastic buffer sheet is installed on the top of the buffer cavity. The bottom surface of the buffer sheet adopts a honeycomb structure, which includes a number of buffering surfaces, so as to increase its force-bearing area and buffering efficiency. When the water flow hits the buffer sheet, the buffer sheet can undergo elastic deformation, significantly reducing the impact force of the water flow, thereby effectively reducing the generation of vibration and noise. In addition, the design of multiple buffering surfaces on the bottom surface of the buffer sheet allows the water flow to be dispersed when passing through the buffer sheet, thereby achieving uniform dispersion of the water flow in all directions. This structure not only improves the stability of the water pump, but also reduces energy loss to a certain extent, thereby improving overall work efficiency.

[0016] 2. The buffer surface can be a combination of convex, flat and concave. This diversified shape design enables the buffer sheet to more effectively adapt to different water flow impact situations in practical applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figures 1 to 3 As shown, the utility model relates to a water pump buffer structure, which aims to effectively reduce the vibration and noise generated during the operation of the water pump and improve the uniformity and stability of the water flow.

[0023] The water pump buffer structure mainly includes an inlet pipe 1, an inlet chamber 2, an outlet chamber 3 and an outlet pipe 4. In this structure, a first one-way valve 5 is arranged between the inlet pipe 1 and the inlet chamber 2. The function of the one-way valve is to ensure that the water flow can only enter the inlet chamber 2 in one direction, thereby preventing the water flow from flowing back and ensuring the stability of the water pump. A water pump drive device 6 (the water pump drive device 6 usually includes a motor, a transmission component, a diaphragm, etc., which is the prior art) is arranged inside the inlet chamber 2 to effectively drive the transportation of the water flow. A second one-way valve 7 is arranged between the inlet chamber 2 and the outlet chamber 3 to ensure that the water flow can smoothly enter the outlet chamber 3 after passing through the inlet chamber 2, and at the same time prevent the reverse flow of the water flow, further enhancing the working efficiency of the water pump.

[0024] The utility model also includes a key innovative design - a buffer chamber 8. The bottom of the buffer chamber 8 is provided with a water inlet 81 connected to the water outlet chamber 3, so that the water flow can be smoothly introduced into the buffer chamber. At the same time, the side of the buffer chamber 8 is provided with a water outlet 82 connected to the water outlet pipe 4, so as to facilitate the smooth discharge of the water flow.

[0025] More importantly, the top of the buffer chamber 8 is equipped with an elastic buffer sheet 83. The bottom surface of the buffer sheet 83 adopts a honeycomb structure, including a plurality of buffer facets 831, so as to increase its force-bearing area and buffering efficiency. When the water flow hits the buffer sheet 83, the buffer sheet can undergo elastic deformation, significantly slowing down the impact force of the water flow, thereby effectively reducing the generation of vibration and noise. In addition, the design of multiple buffer facets 831 on the bottom surface of the buffer sheet 83 allows the water flow to be dispersed when passing through the buffer sheet, thereby achieving uniform dispersion of the water flow in all directions. This structure not only improves the stability of the water pump, but also reduces energy loss to a certain extent, thereby improving overall work efficiency.

[0026] More specifically, the buffer face 831 can be a combination of one or more of a convex surface, a flat surface and a concave surface. This diverse shape design enables the buffer sheet 83 to more effectively adapt to different water flow impact situations in practical applications.

[0027] First, the convex surface design can effectively guide the water flow to spread outward, increase the contact area of ​​the water flow on the surface of the buffer sheet, and thus slow down the speed and impact of the water flow. In this way, the instantaneous pressure generated by the water flow during impact can be effectively reduced, thereby reducing the impact on the water pump structure.

[0028] Secondly, the design of the flat facets provides a stable contact surface, allowing the water flow to maintain a relatively uniform distribution when passing through. This uniformity helps to reduce the vortex caused by uneven water flow when the water flows through the buffer chamber, thereby further reducing noise and vibration.

[0029] The concave design plays an important role in the buffer surface 831. It can form a local low-pressure area, which helps to absorb and buffer the energy of the water flow. This shape design changes the flow path of the water flow, so that the kinetic energy of the water flow can be more fully converted into pressure energy in the buffer cavity, thereby reducing the speed and impact force of the water when it comes out, achieving an effective buffering effect.

[0030] Preferably, the bottom surface of the buffer sheet 83 is designed to protrude toward the inside of the buffer cavity 8. Such a structural design not only enhances the functionality of the buffer sheet, but also provides more effective support for the buffering and dispersion of water flow.

[0031] Specifically, the design of the bottom surface of the buffer sheet 83 protruding inward can increase the contact area with the water flow, forming a more significant contact surface. When the water flow hits the buffer sheet, it can flow better along the protruding surface, thereby effectively reducing the impact force and slowing down the speed of the water flow. This design can effectively disperse the energy of the water flow, avoid the violent reaction caused by the water flow directly hitting the water cavity, and thus reduce the overall vibration and noise.

[0032] In addition, the inward convex shape of the bottom surface also helps to form a local buffer zone, making it easier for water flow to be converted into pressure energy rather than kinetic energy during the flow process. This conversion process not only improves the energy efficiency of the water pump, but also effectively reduces the water hammer phenomenon caused by drastic changes in water flow, protecting the safety of the water pump and its connected pipes.

[0033] In addition, the design of the bottom of the buffer sheet protruding inward can also enhance its elastic effect, so that the buffer sheet can better deform elastically when the water flow hits. This elastic deformation not only further disperses the pressure acting on the buffer sheet, but also can quickly return to its original state when the water flow stops, ensuring the normal operation and stability of the water pump.

[0034] More specifically, the top of the buffer chamber 8 is provided with an opening, and a top cover 84 is installed at the opening, and the top cover 84 is located above the buffer sheet 83 and presses the periphery of the buffer sheet 83. Such a structure is convenient for disassembling and assembling the buffer sheet 83. At the same time, the existence of the top cover greatly enhances the stability and durability of the buffer sheet 83, making it less likely to be excessively deformed when subjected to water flow impact, ensuring that the water pump can still operate stably under high load conditions.

[0035] Furthermore, the top surface of the buffer sheet 83 is provided with a plurality of support columns 832, which not only provide additional support force for the buffer sheet, but also have a certain elasticity. This elastic design enables the support columns 832 to be appropriately compressed and deformed when impacted by water flow, thereby further enhancing the adaptability of the entire buffer structure. The elastic characteristics of the support columns 832 enable them to effectively absorb and disperse the impact force of the water flow, protecting the buffer sheet 83 and the water pump system from excessive impact and pressure. Through the design of the support columns 832, evenly distributed support for the buffer sheet 83 can be achieved to avoid local damage caused by concentrated force.
