Technical Field

[0001] The utility model relates to the technical field of water purifiers, and specifically provides a water purifier. Background Art

[0002] Common household appliances such as water purifiers, washing machines, and dehumidifiers generate noise during operation due to the vibration of the water pump, which affects people's lives. Water purifiers are used more frequently, and people are more concerned about the noise issue of water purifiers. Therefore, it is very necessary to reduce the operating noise of water purifiers.

[0003] Existing water purifiers consist of a housing, a water pump, a mounting plate, and multiple rubber feet. The water pump is fixed to the mounting plate with screws. The rubber feet are fixed to the mounting plate at one end and to the housing at the other. The rubber feet reduce the vibration energy transmitted from the water pump to the housing, thereby reducing noise. However, simply isolating the vibration transmission path of the water pump with the rubber feet is ineffective in reducing noise, resulting in a relatively loud operating noise level for the water purifier, which affects the user experience.

[0008] When the above technical solution is adopted, the water pump can be fixed in the mounting frame by the vibration-damping shell. The vibration-damping shell can vibrate synchronously with the water pump, causing the damping particles in the damping cavity to vibrate and collide, thereby dissipating the vibration energy of the water pump, reducing the vibration energy transmitted by the water pump, and thus reducing the vibration of the water pump.

The damping particles in the damping cavity vibrate and collide to dissipate the vibration energy of the water pump and reduce the vibration of the water pump.

[0013] In the preferred technical solution of the above water purifier, a plug-in groove is provided on the vibration-damping shell, and the end of the water pump is fitted and inserted into the plug-in groove.

[0014] When the above technical solution is adopted, the vibration-damping shell located at the end of the water pump vibrates synchronously with the water pump and supports the water pump at the same time. The damping particles vibrate and collide in the damping cavity, dissipating the vibration energy of the water pump, thereby reducing the vibration of the water pump.

[0015] In the preferred technical solution of the above-mentioned water purifier, the number of the vibration damping devices is set to two, the water pump is located between the two vibration damping shells, and the two ends of the water pump are inserted into the plug-in slots one by one, and the water pump and the two vibration damping shells form a whole that is clamped in the mounting bracket.

[0016] When the above technical solution is adopted, the integral part formed by the water pump and the two vibration-damping shells is snapped into the mounting frame, thereby completing the installation of the water pump, which is easy to operate.

[0017] In the preferred technical solution of the above water purifier, the shape of the vibration-damping shell is set to be the same as the shape of the housing of the water pump, and the vibration-damping shell is fitted on the outside of the housing.

[0041] The following describes preferred embodiments of the present invention with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely intended to illustrate the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0043] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "connected," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed or detachable connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0044] In order to solve the problem that only using rubber foot pads to isolate the vibration transmission path of the water pump has poor noise reduction effect on the water pump, the working noise of the water purifier is still relatively loud, affecting the user experience.

[0045] like Figures 1 to 3 As shown, this embodiment discloses a water purifier, which includes a shell, a mounting bracket 2, a water pump 1 and at least one vibration damping device 3. The mounting bracket 2 is fixed in the shell, and at least one vibration damping device 3 is installed on the water pump 1. The vibration damping device 3 can fix the water pump 1 in the mounting bracket 2, and can also reduce the vibration of the water pump 1 and the working noise of the water pump 1, thereby reducing the working noise of the water purifier and improving the user experience.

[0046] like Figures 1 to 3 As shown, specifically, the vibration damping device 3 includes a vibration damping shell 31, which is connected to the water pump 1 and can vibrate synchronously with the water pump 1. The vibration damping shell 31 is provided with at least one damping chamber 311, which is filled with damping particles 32. When the water pump 1 vibrates, the damping particles 32 vibrate and collide within the damping chamber 311, dissipating the vibration energy of the water pump 1, thereby reducing the vibration of the water pump 1, reducing the vibration energy transmitted from the water pump 1 to the mounting bracket 2, and reducing the operating noise of the water pump 1 and the water purifier. The vibration damping device 3 can also be installed on other vibration sources such as motors, compressors, or fans to achieve vibration and noise reduction of the vibration source.

[0047] The vibration reduction effect of the vibration reduction device 3 is related to the filling rate of the damping particles 32 in the damping chamber 311. The filling rate of the damping particles 32 in the damping chamber 311 is 30%-100%, and the preferred filling rate is 70%-90%, so that the damping particles 32 can better rub and collide to dissipate the vibration energy of the water pump 1. The damping particles 32 include one of metal particles, ceramic particles, rubber particles, and polymer particles, or a mixture of several of these particles. The damping particles 32 include one of the damping particles 32 in the shape of a sphere, a cone, a cube, or an irregular shape, or a mixture of several damping particles 32 of different shapes. The total mass ratio of the damping particles 32 to the mass of the water pump 1 is less than 0.1. At this mass ratio, the damping particles 32 can better dissipate the vibration energy generated by the water pump 1.

[0048] Different water purifiers use water pumps 1 with different loads. According to the different loads of the water pumps 1, damping particles 32 of different materials, sizes and filling rates can be selected to match the load of the water pump 1 to achieve good vibration reduction and noise reduction effects.

[0049] like Figures 1 to 6 As shown, the vibration-damping shell 31 can be set in various shapes so that it can be installed at different positions of the vibration source, so that the vibration source can be installed on the mounting frame 2 in various forms, or the shape of the vibration-damping shell 31 can be selected according to different vibration sources, so that the vibration-damping device 3 can adapt to different installation conditions and working environments.

[0050] like Figures 1 to 3 As shown, the vibration-damping housing 31 is configured to be arc-shaped or annular to match the shape of the water pump 1. In this embodiment, the vibration-damping housing 31 is configured to be arc-shaped, and there are two vibration-damping housings 31. Both vibration-damping housings 31 are sleeved on the outer wall of the water pump 1, and a distance is left between the two vibration-damping housings 31. The vibration-damping housing 31 can support the water pump 1. The vibration-damping housing 31 can be connected to the housing of the water pump 1 by a plurality of fixing screws 33, or by welding, bonding, or other methods.

[0051] Multiple vibration-damping pads 4 are connected between the bottom of the vibration-damping housing 31 and the mounting frame 2. These rubber or silicone pads 4 are secured between the vibration-damping housing 31 and the mounting frame 2 via set screws 5. When the water pump 1 vibrates, the two vibration-damping housings 31 vibrate synchronously with the water pump 1. The damping particles 32 vibrate and collide within the damping chamber 311, dissipating the vibration energy of the water pump 1. This reduces the vibration of the water pump 1 and the vibration energy transferred from the water pump 1 to the vibration-damping housing 31. The vibration-damping pads 4 reduce the vibration energy transferred from the vibration-damping housing 31 to the mounting frame 2, thereby reducing the vibration energy transferred to the outer casing and reducing the operating noise of the water purifier.

[0052] like Figure 4As shown, the vibration damping housing 31 is provided with a clearance groove 312 that matches the shape of the water pump 1. The sidewall of the water pump 1 is placed in the clearance groove 312 and connected to the vibration damping housing 31. There is only one vibration damping housing 31, shaped like a cube. The clearance groove 312 is located at the top of the vibration damping housing 31. Multiple fixing screws 33 connect the vibration damping housing 31 to the housing of the water pump 1. Similarly, the vibration damping housing 31 can also be fixed to the housing of the water pump 1 by welding or bonding.

[0053] Multiple vibration-damping pads 4 are evenly spaced across the bottom of the vibration-damping housing 31. These pads are secured between the vibration-damping housing 31 and the mounting bracket 2 via set screws 5. When the water pump 1 vibrates, the vibration-damping housing 31 at its base vibrates synchronously with the pump 1. The damping particles 32 vibrate and collide within the damping chamber 311, dissipating the vibration energy of the pump 1. This reduces the vibration of the pump 1 and the vibration energy transferred from the pump 1 to the vibration-damping housing 31. The vibration-damping pads 4 reduce the vibration energy transferred from the vibration-damping housing 31 to the mounting bracket 2, thereby reducing the vibration energy transferred to the outer casing and reducing the operating noise of the water purifier.

[0054] like Figure 5 As shown, the vibration damping shell 31 is provided with a plug-in slot 313, and the end of the vibration source is inserted into the plug-in slot 313. The number of vibration damping shells 31 is set to two, and the shape is set to be cylindrical. The end of the vibration damping shell 31 is provided with a plug-in slot 313 that matches the end of the water pump 1. Both ends of the water pump 1 are inserted into the corresponding plug-in slot 313, so that the two vibration damping shells 31 can support the water pump 1. The integral fitting formed by the water pump 1 and the two vibration damping shells 31 is inserted into the mounting frame 2 to complete the installation of the water pump 1, which has good operational convenience. Of course, the shape of the vibration damping shell 31 can also be set to a rectangular, triangular or irregular shape to adapt to different installation spaces. It is only necessary to make the plug-in slot 313 match the end of the water pump 1.

[0055] When the water pump 1 vibrates, the vibration-damping shells 31 at both ends of the water pump 1 vibrate synchronously with the water pump 1, and the damping particles 32 vibrate and collide in the damping chamber 311, dissipating the vibration energy of the water pump 1, thereby reducing the vibration of the water pump 1 and reducing the vibration energy transmitted from the water pump 1 to the vibration-damping shell 31, thereby reducing the vibration energy transmitted to the mounting bracket 2 and reducing the working noise of the water purifier.

[0056] like Figure 6 As shown, the shape of the vibration damping housing 31 is designed to be the same as the housing of the water pump 1. The vibration damping housing 31 is fitted over the exterior of the water pump 1 housing to achieve connection between the vibration damping housing 31 and the water pump 1. The vibration damping housing 31 can also be directly used as the housing of the water pump 1 to reduce the cost of the water pump 1. The vibration damping housing 31 is connected to the mounting bracket 2 by snap-fitting, welding, or bolting to achieve installation of the water pump 1.

[0057] When the water pump 1 vibrates, the vibration-damping shell 31 vibrates synchronously with the water pump 1, and the damping particles 32 vibrate and collide in the damping chamber 311, dissipating the vibration energy of the water pump 1, thereby reducing the vibration of the water pump 1 and reducing the vibration energy transmitted from the water pump 1 to the vibration-damping shell 31, thereby reducing the vibration energy transmitted to the mounting bracket 2 and reducing the working noise of the water purifier.

[0058] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
