Description

Technical Field

[0001] This utility model relates to the field of booster pump design technology, and in particular to a booster pump structure and a water purifier. Background Technology

[0002] The booster pump in a water purifier is a key component ensuring effective filtration of water through the filter cartridge. Because its working principle involves mechanical motion and hydrodynamic changes, and current booster pumps are developing towards higher power and flow rates, this leads to increased size, pressure, and noise. Booster pumps inevitably generate noise during operation and are prone to shaking and displacement. This amplifies the noise from the water purifier itself, affecting user experience and potentially causing adverse health effects with prolonged exposure to high decibel levels. Therefore, the location and method of fixing the booster pump directly impacts the equipment's operational stability and lifespan; reducing booster pump noise has become a crucial issue in improving water purifier performance.

[0003] The commonly used fixing method is to fix the booster pump to the bottom of the machine. The booster pump is mainly directly and rigidly connected to the equipment frame by bolts. However, for the rigid fixing method, although the bolts can directly anchor the booster pump housing to ensure structural strength, the high-frequency vibration generated by the pump body during operation will be directly transmitted to the equipment frame through the rigid connection path, causing the housing to resonate and generate obvious noise.

[0004] Therefore, it is particularly important to develop a booster pump structure and water purifier that can reduce the contact area between the booster pump body and other parts, thereby reducing the vibration and noise of the water purifier. Utility Model Content

[0032] Currently, the commonly used method of fixing the booster pump is to fix it to the bottom of the machine. The booster pump is mainly directly and rigidly connected to the equipment frame by bolts. However, the high-frequency vibration generated by the pump body during operation is directly transmitted to the equipment frame through the rigid connection path, causing the casing to resonate and generate significant noise. Therefore, in order to reduce the contact area between the booster pump body and other parts and reduce the vibration noise of the water purifier, this application provides a booster pump structure and a water purifier.

[0033] Please see Figure 1 , Figure 1 This is a schematic diagram of a water purifier booster pump structure according to an embodiment of the present invention. The booster pump structure provided in this application includes a booster pump body 1, a bracket structure 2, a support structure 3, and a gasket structure 4; the bracket structure 2 is arranged around both ends of the booster pump body 1, the support structure 3 is arranged below the bracket structure 2, and the gasket structure 4 is arranged below the support structure 3; the support structure 3 is fixedly connected to the bracket structure 2 and the gasket structure 4 respectively.

[0034] The support structure 2 is polygonal in shape, and each side of the support structure 2 is tangent to the booster pump body 1.

[0035] The support structure 3 includes a columnar support device 31 and an elastic support device 32. The columnar support device 31 is disposed below the bracket structure 2, and the elastic support device 32 is disposed below the columnar support device 31. The columnar support device 31 is fixedly connected to the bracket structure 2 and the elastic support device 32 respectively.

[0036] The gasket structure 4 is disposed below the elastic support device 32, and the gasket structure 4 is fixedly connected to the elastic support device 32.

[0037] Optionally, the booster pump structure is located at the bottom of the water purifier. The water purifier is equipped with an electronic control board 5 and a power supply line 6. The electronic control board 5 is located at the top of the water purifier for easy user control. The electronic control board 5 is used for the operation of the electrical load of the whole machine, and the power supply line 6 is used to supply power to the booster pump body 1 from the electronic control board 5.

[0038] Optionally, the booster pump is used to provide power for the water inside the water purifier. When the booster pump is started, the power supply mode of the electronic control board 5 is low-voltage start, that is, soft start mode. Before the booster pump is running normally, the voltage of the booster pump is first adjusted to a low-voltage state, and then gradually increased to the rated voltage, and finally reaches the normal operating state. By gradually increasing the power supply voltage, the current surge and mechanical stress during startup are reduced, thereby greatly reducing the noise of the booster pump during cold start, while protecting the power supply system and load equipment and extending their service life.

[0039] Optionally, the support structure 3 and the bracket structure 2 can be fixedly connected by welding, and the support structure 3 and the gasket structure 4 can be fixedly connected by adhesive.

[0040] Optionally, each side of the support structure 2 is tangent to the booster pump body 1, and the tangency points are on the same plane. The tangential contact method makes the contact between the booster pump and the support more stable, reduces the need for additional support structures and the displacement of the booster pump due to vibration during operation. Furthermore, the weight of the booster pump body 1 can be evenly distributed to the contact points, and the vibration energy will be distributed to different paths during transmission, rather than concentrated on a straight line. This uniform pressure distribution can effectively reduce local stress concentration and avoid vibration and noise caused by uneven pressure.

[0041] Optionally, the booster pump body 1 is fixed on two bracket structures 2, and simultaneously fixed to the bottom of the water purifier via the support structure 3 and the gasket structure 4. This overall structure, by fixing the booster pump body 1 to the bracket structure 2 and connecting it to the bottom of the water purifier via the support structure 3 and the gasket structure 4, forms a multi-stage shock absorption system. The elastic support device 32 and the gasket structure 4 can effectively absorb and attenuate the vibration energy generated during the operation of the booster pump. This design changes the contact method between the booster pump and the bottom of the water purifier from the traditional surface contact to point contact or line contact, greatly reducing the contact area, thereby effectively reducing resonance and lowering the vibration and noise of the entire machine.

[0042] In an optional embodiment, the support structure 2 is equilateral triangle in shape. The support structure 2 includes a first support device 21 and a second support device 22. The first support device 21 and the second support device 22 are symmetrically arranged on the booster pump body 1. The support structure 2 is detachably connected to the booster pump body 1.

[0043] In an optional embodiment, the distance between the first support device 21 and one end of the booster pump body 1 is greater than a preset distance.

[0044] Optionally, the support structure 2 has a certain degree of elasticity. The support structure 2 relies on its own elasticity to wrap around the booster pump body 1 and is detachably connected to the booster pump body 1.

[0045] Optionally, the preset distance can be set according to actual business needs, and is not limited here. For example, the distance between the first support device 21 and the second support device 22 and one end of the booster pump body 1 is greater than 5cm. The first support device 21 and the second support device 22 are symmetrically arranged at both ends of the booster pump body 1. Maintaining a distance between the support structure 2 and one end of the booster pump body 1 can avoid mechanical interference between the booster pump body 1 and the support during operation, which would lead to increased vibration of the booster pump or even damage to components. The symmetrical arrangement helps to improve the overall stress stability of the structure.

[0046] Optionally, the bracket structure 2 is shaped like an equilateral triangle. An equilateral triangle has high symmetry and balance, thus providing strong stability. This reduces the vibration of the booster pump body 1 during operation, avoiding noise and component wear caused by vibration. Furthermore, the triangular bracket design makes it easier to disassemble or adjust, facilitating daily maintenance and inspection. The two triangular brackets can distribute the weight of the booster pump body 1, reducing pressure on the mounting surface and preventing deformation or damage from long-term use.

[0047] Alternatively, the shape of the support structure 2 can also be other polygons. For example, the support structure 2 can be a rectangle, pentagon, hexagon, etc. However, in some cases, the stability and symmetry of other polygonal structures are not as good as those of equilateral triangles, and equilateral triangle structures are more advantageous in some space-constrained scenarios.

[0048] In an optional embodiment, the columnar support device 31 includes a first support column 311, a second support column 312, a third support column 313, and a fourth support column 314. The first support column 311 and the second support column 312 are fixedly connected to both ends of the first bracket device 21, and the third support column 313 and the fourth support column 314 are fixedly connected to both ends of the second bracket device 22.

[0049] In an optional embodiment, the first support column 311 and the second support column 312 are symmetrically arranged below the first support device 21, and the third support column 313 and the fourth support column 314 are symmetrically arranged below the second support device 22.

[0050] Optionally, the cylindrical support device 31 is cylindrical in shape, and the width of the bottom surface of the bracket structure 2 is smaller than the diameter of the cylindrical support device 31.

[0051] Optionally, the first support column 311, the second support column 312, the third support column 313, and the fourth support column 314 are cylindrical in shape, with the same diameter and height. The diameter and height of the column support device 31 can be set according to actual business needs and are not limited here. The diameter of the column support device 31 should be larger than the width of the bottom surface of the support structure 2, which can reduce the contact area between the support structure 2 and other parts. This helps to reduce the efficiency of vibration transmission from the booster pump body 1 to the support structure 3, significantly optimize the vibration reduction effect, reduce vibration transmission, improve the stability and reliability of the system, and optimize the spatial layout.

[0052] Optionally, the first support column 311 and the second support column 312 can be symmetrically arranged at any position at both ends of the first support device 21, and the first support column 311, the second support column 312, the third support column 313, and the fourth support column 314 can be fixedly connected to the first support device 21 and the second support device 22 by welding.

[0053] Optionally, in scenarios requiring higher stability and shock absorption, the number of column support devices 31 can be increased. For example, three column support devices 31 are uniformly arranged and fixedly connected below the first support device 21 and the second support device 22, respectively.

[0054] By setting up symmetrical columnar support devices 31, the weight of the booster pump body 1 can be evenly distributed to each support point. This evenly distributed load can effectively reduce local stress concentration, avoid structural deformation or damage caused by uneven load, and thus improve the stability of the entire structure. Furthermore, during operation, the booster pump body 1 may generate overturning moments due to vibration or other external forces. The symmetrical support columns can effectively resist these moments, ensuring the booster pump remains stable during operation, enhancing the system's anti-overturning capability, and reducing the risk of failure due to overturning. The columnar support devices 31 ensure that vibration energy is evenly distributed during transmission, reducing vibration transmission in one direction, thereby reducing vibration and noise.

[0055] In an optional embodiment, the elastic support device 32 includes a first spring post 321, a second spring post 322, a third spring post 323, and a fourth spring post 324. The first spring post 321 is fixedly connected below the first support post 311, the second spring post 322 is fixedly connected below the second support post 312, the third spring post 323 is fixedly connected below the third support post 313, and the fourth spring post 324 is fixedly connected below the fourth support post 314.

[0056] Optionally, the first spring post 321, the second spring post 322, the third spring post 323, and the fourth spring post 324 can be fixedly connected to the first support post 311, the second support post 312, the third support post 313, and the fourth support post 314 by welding.

[0057] Optionally, the diameter, number of coils, and stiffness of the elastic support device 32 can be set according to actual business needs, and are not limited here. For example, a nonlinear spring can be used to provide a more flexible damping effect according to different loads and vibration frequencies, or a composite spring combining springs of different materials such as metal springs and rubber springs can be used.

[0058] Optionally, the elastic support device 32 can achieve a suspended installation effect. The spring has good elasticity and can impede the work done by the booster pump. When the booster pump vibrates, the spring will absorb this energy through elastic deformation, effectively absorbing the vibration energy generated by the booster pump during operation. By absorbing and attenuating vibration energy, the spring can significantly reduce the wear of the booster pump and its related components. This design not only reduces the frequency of maintenance and replacement of parts, but also extends the service life of the entire system, reduces long-term operating costs, and improves the overall reliability of the system.

[0059] In an optional embodiment, the gasket structure 4 includes a first gasket 41, a second gasket 42, a third gasket 43, and a fourth gasket 44. The first gasket 41 is fixedly connected to the lower part of the first spring post 321, the second gasket 42 is fixedly connected to the lower part of the second spring post 322, the third gasket 43 is fixedly connected to the lower part of the third spring post 323, and the fourth gasket 44 is fixedly connected to the lower part of the fourth spring post 324.

[0060] In an optional embodiment, the centers of the first gasket 41, the second gasket 42, the third gasket 43, and the fourth gasket 44 are on the same plane and form a rectangle.

[0061] Optionally, the material of the gasket structure 4 can be set according to actual business needs, and is not limited here. For example, the gasket structure 4 can be a silicone gasket, or a rubber gasket or a polyurethane gasket, to achieve higher wear resistance and shock absorption effect.

[0062] Optionally, the gasket structure 4 can be configured as a double-layer gasket, and multiple gasket structures 4 made of different materials can be combined to further improve the shock absorption effect.

[0063] Optionally, the first gasket 41, the second gasket 42, the third gasket 43, and the fourth gasket 44 can be fixedly connected to the first spring post 321, the second spring post 322, the third spring post 323, and the fourth spring post 324 respectively by adhesive bonding.

[0064] Optionally, the first gasket 41, the second gasket 42, the third gasket 43, and the fourth gasket 44 can be fixedly connected to the bottom of the water purifier by adhesive.

[0065] Optionally, the four columnar support devices 31 and the four elastic support devices 32 are symmetrical in pairs, so that the centers of the first gasket 41, the second gasket 42, the third gasket 43, and the fourth gasket 44 form a rectangle on the same plane. The gasket structure 4 can effectively reduce the vibration transmitted from the booster pump to the bottom of the water purifier, and at the same time distribute the weight of the booster pump evenly to the four support points, thereby effectively reducing local stress concentration and forming a point contact method, which greatly reduces the contact area, solves the vibration and noise problem of the whole machine, and thus improves the stability of the entire system.
