[0002] In conventional water pump (for example, used in fish tank), the water outlet structure usually adopts straight-through structure, that is, the water flow directly from the water outlet chamber to the water outlet pipe.

[0027] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] With reference to Figures 1 to 5 , the present embodiment discloses a water pump reinforced damping structure, which aims to significantly reduce the vibration and noise during the operation of the water pump, and improve the uniformity and stability of the water flow. The core of the structure is that a buffer chamber is integrated at the water outlet end of the water pump, and through multiple damping mechanisms, the water flow pulsation is effectively absorbed and attenuated, thereby achieving the above-mentioned goals.

[0029] The water pump reinforced damping structure mainly includes a pump body 1, an inlet pipe 11, an inlet cavity 12, an outlet cavity 13 and an outlet pipe 14 integrated on the pump body 1. In order to ensure the one-way flow of water, a first one-way valve 2 is arranged at the connection between the inlet pipe 11 and the inlet cavity 12 to prevent backflow of water. A pump water driving device 3 is installed inside the inlet cavity 12, which is the core power source of the water pump and is responsible for driving the water flow. It is worth noting that the pump water driving device 3 is usually composed of a motor, a transmission assembly and a diaphragm, which are all prior art and will not be described here. In order to further control the direction of water flow, a second one-way valve 4 is also arranged between the inlet cavity 12 and the outlet cavity 13 to ensure that the water flow can only flow from the inlet cavity to the outlet cavity. The special part is that between the outlet cavity 13 and the outlet pipe 14, the core component of this embodiment, the buffer cavity 15, is arranged.

[0030] The bottom of the buffer cavity 15 is provided with a water inlet 151 connected with the outlet cavity 13, so as to introduce the water flow into the buffer cavity. The side wall of the buffer cavity 15 is provided with a water outlet 152 connected with the outlet pipe 14, so as to guide the water flow out after damping. At the top of the buffer cavity 15, an open mouth 153 is designed, and an elastic damping sheet 5 is arranged at the open mouth 153. The damping sheet 5 is the first line of defense for water flow pulsation and can absorb most of the impact energy.

[0031] In order to further enhance the damping effect, a top cover 6 is arranged on the upper side of the damping sheet 5. The top cover 6 is detachably (such as threaded connection) installed at the open mouth 153 and tightly presses the periphery of the damping sheet 5 from above, forming a stable support structure. More importantly, a damping spring 7 is arranged between the top cover 6 and the damping sheet 5, which can elastically press the damping sheet 5 downward. The damping spring 7 greatly improves the damping performance of the damping sheet 5 and increases the damping of the entire structure, thereby achieving better damping effect. The damping spring 7 is like an additional elastic element, which can further absorb the impact energy of water flow and convert it into a small deformation, thereby reducing the impact on the water pump system.

[0032] Further, a damping adjustment structure for adjusting the compression degree of the damping spring 7 is arranged between the upper end of the damping spring 7 and the top cover 6. This structure aims to provide users with flexible damping force adjustment options to adapt to different working conditions. Through the damping adjustment structure, users can conveniently adjust the initial compression degree of the damping spring 7, which directly affects the damping force it can generate. This function enables the equipment to better cope with instantaneous water flow changes and vibration impacts during operation, providing more stable working performance.

[0033] Specifically, the damping adjustment structure includes an upper spring seat 61 connected to the inner top surface of the top cover 6 in a sliding manner along the up-down direction. The upper spring seat 61 can move up and down within the limiting range of the top cover 6, thereby changing the contact pressure between it and the damping spring 7, and further adjusting the compression degree of the damping spring 7.

[0034] In addition, the damping adjustment structure also includes a threaded hole 62 arranged on the top surface of the top cover 6. An adjusting top screw 63 is installed in the threaded hole 62, and the lower end of the adjusting top screw 63 can be in close contact with the upper spring seat 61. By rotating the adjusting top screw 63, the height of the upper spring seat 61 can be accurately adjusted. Specifically, when the adjusting top screw 63 is rotated downward, the lower end of the top screw will press the upper spring seat 61, causing it to move downward. At this time, the compression degree of the damping spring 7 increases, and the damping force generated also increases. Conversely, when the adjusting top screw 63 is rotated upward, the upper spring seat 61 will rise due to the reduction of pressure, the compression degree of the damping spring 7 decreases, and the damping force generated will also decrease accordingly.

[0035] In summary, the damping adjustment structure not only provides effective control of the damping spring 7, but also makes the operation of the device more efficient and customizable through a simple adjustment mechanism, and is more adaptable to different use environments and needs of users. This innovative design brings great convenience to the use of the water pump, ensuring that users can obtain the best operating performance in various working conditions.

[0036] In order to make the pressure of the damping spring 7 act uniformly on the damping sheet 5 and avoid local stress concentration, the embodiment also specially designs a pressing sheet 8. The pressing sheet 8 is located between the lower end of the damping spring 7 and the upper surface of the damping sheet 5, and its lower surface is tightly fitted on the center position of the upper surface of the damping sheet 5. The pressing sheet 8 effectively increases the force bearing area between the damping spring 7 and the damping sheet 5, which is beneficial to dispersing the pressure to each position of the damping sheet 5, avoiding pressure concentration, thereby prolonging the service life of the damping sheet.

[0037] In terms of material selection, the embodiment is also optimized. The pressing sheet 8 is preferably made of plastic material, which has a certain hardness and can effectively transmit and disperse the pressure. The damping sheet 5 is preferably made of soft rubber material, such as rubber or silicone. Such soft material has good elasticity and can effectively absorb impact energy. Through the combination of hard pressing sheet and soft damping sheet, a damping effect of rigidity and flexibility is achieved.

[0038] To further enhance the performance of the damping sheet 5, a number of support columns 51 are also provided on its upper surface. These support columns 51 are also elastic, providing additional support to the damping sheet and possessing a certain degree of elasticity. This elastic design allows the support columns 51 to be moderately compressed and deformed when impacted by water flow, further enhancing the adaptability of the entire damping structure. The elastic properties of the support columns 51 enable them to effectively absorb and disperse the impact force of the water flow, protecting the damping sheet 5 and the water pump system from excessive impact and pressure. Through the design of the support columns 51, uniform distribution of support to the damping sheet 5 can be achieved, avoiding local damage caused by concentrated stress.

[0039] To ensure that the top pressing sheet 8 can be accurately installed on the damping sheet 5 and avoid interference with the support columns 51, a number of through holes 81 are also provided on the top pressing sheet 8 for the corresponding support columns 51 to pass through. The cooperation between the through holes 81 and the support columns 51 not only provides positioning for the installation of the top pressing sheet 8, but also ensures that the support columns 51 can deform freely when compressed without being hindered by the top pressing sheet 8.

[0040] Furthermore, the lower surface of the top cover 6 is provided with an upper spring seat 61 in the center, which is used to install the upper end of the spring, and the upper surface of the top pressing sheet 8 is also provided with a lower mounting seat 82 in the center for installing the lower end of the spring. In this embodiment, the upper spring seat 61 includes an annular mounting hole and an upper mounting column in the center of the mounting hole; the lower mounting seat 82 includes a lower mounting column, and the upper and lower ends of the damping spring 7 are respectively sleeved on the upper and lower mounting columns.

[0041] Furthermore, the bottom surface of the damping sheet 5 adopts a honeycomb structure, containing a number of buffer facets 52, in order to increase its stress area and damping efficiency. When water flow impacts the damping sheet 5, the damping sheet can elastically deform, significantly reducing the impact force of the water flow, thereby effectively reducing vibration and noise. In addition, the design of multiple buffer facets 52 on the bottom surface of the damping sheet 5 allows the water flow to be dispersed when passing through the damping sheet, achieving uniform dispersion of water flow in all directions. This structure not only improves the stability of the water pump, but also reduces energy loss to some extent, improving overall work efficiency.

[0042] Furthermore, the buffer facets 52 are one or more of convex, flat, and concave. This diverse shape design allows the damping sheet 5 to more effectively adapt to different water flow impact situations in actual application.

[0043] Firstly, the convex design can effectively guide the water flow to diffuse outward, increasing the contact area of the water flow on the surface of the damping sheet, thereby reducing the speed and impact force of the water flow. In this way, the instantaneous pressure generated by the water flow when it impacts can be effectively reduced, thereby reducing the impact on the water pump structure.

[0044] Secondly, the design of the flat facets provides a stable contact surface, so that the water flow can maintain a more uniform distribution when passing through. This uniformity helps to reduce the vortex caused by uneven water flow when the water flow passes through the buffer cavity, thereby further reducing noise and vibration.

[0045] And the concave design plays an important role in the buffer facet 52, which can form a local low-pressure area, helping to absorb and dampen the energy of the water flow. The design of this shape 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 when the water is discharged, achieving the effect of effective damping.

[0046] Further, the middle of the damping sheet 5 is downwardly convex (that is, downwardly convex). Such a structural design not only enhances the functionality of the damping sheet, but also provides more effective support for the damping and dispersion of the water flow.

[0047] Specifically, the design of the downwardly convex middle of the bottom surface of the damping sheet 5 can increase the contact area with the water flow, forming a more significant contact surface. When the water flow impacts the damping sheet, it can flow better along the convex 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, avoiding the violent reaction caused by the water flow directly impacting the water outlet cavity, thereby reducing the overall vibration and noise.

[0048] In addition, the downwardly convex shape of the bottom surface also helps to form a local damping area, so that the water flow can be more easily converted into pressure energy during the flow process, rather than kinetic energy. This conversion process not only improves the energy efficiency of the water pump, but also effectively reduces the water hammer phenomenon caused by the violent change of the water flow, protecting the safety of the water pump and its connected pipeline.

[0049] In addition, the design of the downwardly convex bottom surface of the damping sheet can also enhance its elastic effect, so that when the water flow impacts, the damping sheet can better elastically deform. This elastic deformation not only further disperses the pressure acting on the damping sheet, but also can quickly recover to its original state when the water flow stops, ensuring the normal operation and stability of the water pump.

[0050] Through the synergistic effect of the above multiple damping mechanisms, the water pump damping structure disclosed in the embodiment can effectively reduce the vibration and noise generated during the operation of the water pump, improve the uniformity and stability of the water flow, and thereby improve the service life and performance of the water pump.
