In recent years, the water purification industry is rapidly developed and gradually popularized. The water purifier brings convenience to people and brings troubles to people, such as vibration and noise generated when the water purifier is used.

The noise sources of the water purifier mainly comprise booster pump noise, pipeline vibration noise, electromagnetic valve noise, waste water valve noise and the like. However, the booster pump, which is the most central component of the water purifier, is the "heart" of the water purifier, and the noise generated during the operation is particularly prominent. Tests show that the noise of the whole single-test water purifier is 46.7dB, the noise of the single booster pump is 45.3dB, and the booster pump noise accounts for more than 80% of the noise of the whole water purifier and is the most main noise source. Therefore, it is important to reduce vibration and noise of the booster pump to reduce noise of the entire water purifier and to reduce vibration of the entire water purifier.

The noise of the booster pump mainly includes structural noise and body radiation noise. The structural noise is low-frequency vibration noise generated by vibration of a shell and a pipeline of the surrounding water purifier caused by the booster pump in the operation process; the booster pump also operates to transmit noise through the air, i.e., bulk radiated noise. These will directly affect the user experience.

To the vibration and the noise problem of booster pump, at present, main solution sets up the damping pad at the pump head of booster pump, perhaps all sets up the damping pad in the pump head and the motor department of booster pump to alleviate the vibration of booster pump, thereby the noise reduction.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments of the present invention described by referring to the drawings are exemplary and intended to be illustrative of the present invention, and are not to be construed as limiting the present invention.

The present invention first provides a pump assembly for a water purifier, fig. 1 is a schematic structural view of a pump assembly for a water purifier according to one embodiment of the present invention, and fig. 2 is a schematic structural exploded view of a pump assembly for a water purifier according to one embodiment of the present invention. Referring to fig. 1 and 2, a pump assembly 1 for a water purifier of the present invention includes a housing 10 and a booster pump 20 disposed inside the housing 10.

The housing 10 includes a main housing 11 opened toward one side and a cover 12 detachably coupled to the main housing 11 and covering an opening 111 of the main housing 11. The first and second elastic cushion members 30 and 40 are respectively provided at both ends of the booster pump 20 in the axial direction, and the first and second elastic cushion members 30 and 40 are configured to form a pre-assembly with the booster pump 20, the pre-assembly being mounted in the main casing 11 as a whole through the opening 111 and removed from the main casing 11 as a whole through the opening 111.

That is, the housing 10 includes a main housing 11 and a cover 12 detachably connected, and an opening 111 is formed at one side of the main housing 11 to facilitate the assembly and disassembly of the pre-assembly. The cover 12 detachably covers the opening 111 of the main casing 11 to prevent the booster pump 20, the first elastic buffer 30 and the second elastic buffer 40 from being exposed, and defines a closed cavity inside the casing 10, which can reduce the outward spread of noise to some extent. The first elastic buffer member 30 and the second elastic buffer member 40 are respectively arranged at two axial ends of the booster pump 20, and the first elastic buffer member 30 and the second elastic buffer member 40 can buffer the vibration of the booster pump 20, so that the vibration transmitted to the casing 10 or other parts by the booster pump 20 is reduced, and the noise generated by the whole pump assembly 1 is reduced.

In particular, the booster pump 20 forms a pre-assembly with the first and second elastic cushion members 30 and 40, which can be mounted in the main casing 11 through the opening 111 of the main casing 11 or removed from the main casing 11 through the opening 111 as a whole. That is, during assembly, the booster pump 20, the first elastic buffer member 30 and the second elastic buffer member 40 may be assembled together to form a pre-assembly, and then the pre-assembly is installed in the main housing 11, and finally the cover 12 is connected to the main housing 11, so as to avoid the problem that the assembly difficulty of the booster pump 20, the first elastic buffer member 30 and the second elastic buffer member 40 is large due to the small assembly space in the main housing 11. When the booster pump 20 needs to be maintained, debugged or replaced, the cover body 12 is detached from the main casing 11, and then the pre-assembly part formed by the booster pump 20, the first elastic buffer member 30 and the second elastic buffer member 40 is taken out of the main casing 11, so that the problem that the booster pump is detached only with high difficulty due to the compact structure in the main casing 11 is solved. It can be seen that the mounting operation and the dismounting operation of the booster pump 20 are both simple, which is convenient for the user or the professional to operate, and improves the assembly efficiency and the dismounting efficiency of the pump assembly 1.

Specifically, the main housing 11 and the cover 12 may be detachably connected by a fastener such as a screw, or may be detachably connected by snapping, fastening, or the like.

In some embodiments, the pump assembly 1 further comprises a water inlet tube 50 and a water outlet tube 60 connected to the booster pump 20. It will be appreciated that the inlet and outlet pipes 50 and 60 may communicate with the inlet and outlet ports, respectively, of the booster pump 20. The water inlet and the water outlet of the booster pump 20 are both located at the pump head of the booster pump 20.

Further, the main housing 11 is provided with a water inlet 112 for the water inlet pipe 50 to pass through and a water outlet 113 for the water outlet pipe 60 to pass through, the water inlet 112 and the water outlet 113 are both semi-closed holes opened toward one side of the cover 12, that is, the water inlet 112 and the water outlet 113 are not both closed holes but are semi-closed holes opened at one side, and the openings of the water inlet 112 and the water outlet 113 are both opened toward the side where the cover 12 is located. Thus, in the process of assembling the pre-assembly formed by the booster pump 20, the first elastic buffer member 30 and the second elastic buffer member 40 into the main housing 11, the water inlet pipe 50 and the water outlet pipe 60 connected to the booster pump 20 may be respectively snapped into the water inlet hole 112 and the water outlet hole 113, and it is not necessary to separately penetrate the water inlet pipe 50 and the water outlet pipe 60 out of the main housing 11 after assembling the pre-assembly into the main housing 11.

Further, the cover 12 is configured to close the water inlet hole 112 and the water outlet hole 113 after being coupled to the main housing 11. Thereby, the water inlet pipe 50 and the water outlet pipe 60 are prevented from coming out of the water inlet hole 112 and the water outlet hole 113.

When the pre-assembly is removed from the main housing 11, the cover 12 is separated from the main housing 11, so that the inlet pipe 50 and the outlet pipe 60 can be automatically moved out of the inlet hole 112 and the outlet hole 113 together with the pre-assembly without additional operations. From this, this application has avoided inlet tube 50 and outlet pipe 60 to bring the inconvenience of operation to the dismouting of booster pump 20 through the structural design to main casing body 11 to further improve the convenience of booster pump 20 dismouting.

Fig. 3 is a schematic exploded structural view of a booster pump, a first elastic buffer and a second elastic buffer according to one embodiment of the present invention. In some embodiments, the first elastic buffering member 30 or the second elastic buffering member 40 is provided with a first limiting hole 41 for allowing the water inlet pipe 50 to pass therethrough and limiting the water inlet pipe 50, and a second limiting hole 42 for allowing the water outlet pipe 60 to pass therethrough and limiting the water outlet pipe 60, so that the water inlet pipe 50 and the water outlet pipe 60 are respectively retained in the first limiting hole 41 and the second limiting hole 42 during the mounting and dismounting of the pre-assembly. Therefore, the booster pump 20, the first elastic buffer member 30, the second elastic buffer member 40, the water inlet pipe 50 and the water outlet pipe 60 can jointly form a pre-assembly member with a compact structure, the arrangement of the water inlet pipe 50 and the water outlet pipe 60 is tidy, and inconvenience brought to operators due to the scattered water inlet pipe 50 and the scattered water outlet pipe 60 in the installation and disassembly processes of the pre-assembly member is avoided. Moreover, the first elastic buffering member 30 or the second elastic buffering member 40 has an elastic buffering effect, so that the first limiting hole 41 and the second limiting hole 42 can also respectively buffer the vibration of the water inlet pipe 50 and the water outlet pipe 60, the vibration amplitude of the water inlet pipe 50 and the water outlet pipe 60 is reduced, and the operation noise of the pump assembly 1 is further reduced.

In some embodiments, the booster pump 20 may include a motor 21 and a pump head 22, the first elastic buffer member 30 is disposed outside the pump head 22, and the second elastic buffer member 40 is disposed outside an end of the motor 21 away from the pump head 22. Therefore, the first elastic buffer member 30 can buffer the vibration of the pump head 22 in the radial direction of the booster pump 20, the second elastic buffer member 40 can buffer the vibration of the motor 21 in the radial direction of the booster pump 20, and the first elastic buffer member 30 and the second elastic buffer member 40 can buffer the vibration of the motor 21 and the pump head 22 in the axial direction of the booster pump 20 in a matching manner.

Since the water inlet pipe 50 and the water outlet pipe 60 are both led out from the pump head 22, the first limiting hole 41 and the second limiting hole 42 are both formed in the second elastic buffer 40, and the first limiting hole 41 and the second limiting hole 42 penetrate through the second elastic buffer 40 along the axial direction of the booster pump 20. The inlet tube 50 and outlet tube 60 are thus caused to pass directly out through the side of the main housing 11 remote from the pump head 22, so that the inlet tube 50 and outlet tube 60 are straight, with little bending or kinking, and therefore offer little resistance to water flow.

In some embodiments, the first elastic buffer 30 and the pump head 22, and the second elastic buffer 40 and the motor 21 are connected by interference fit. The connection mode is simple and convenient to operate and firm in connection, the booster pump 20, the first elastic buffer member 30 and the second elastic buffer member 40 can form a pre-assembly member with a stable structure, and the pre-assembly member is prevented from being scattered or scattered in the mounting or dismounting process.

In some embodiments, the main housing 11 has a first end plate 114 adjacent to the second elastic buffer 40 and extending perpendicular to the axial direction of the booster pump 20, the water inlet hole 112 and the water outlet hole 113 are both formed on the first end plate 114 and are located at the edge portion of the first end plate 114 adjacent to the cover 12, and the first limiting hole 41 and the second limiting hole 42 are both formed at the edge portion of the second elastic buffer 40 adjacent to the cover 12. Therefore, the water inlet pipe 50 and the water outlet pipe 60 can be conveniently and directly clamped into the water inlet hole 112 and the water outlet hole 113 from the side of the opening 111, and the water inlet pipe 50 and the water outlet pipe 60 are further prevented from being bent.

In some embodiments, the first and second elastic buffers 30 and 40 are both elastic rubber pads or elastic silicone pads. Elastic rubber pad or elastic silica gel pad can cladding a plurality of sides of booster pump 20 tip to carry out the damping and fall the noise, the effect preferred to booster pump 20 on a plurality of directions.

In alternative embodiments, the first and second elastic buffers 30 and 40 may be springs, elastic cotton, or other components capable of elastic buffering.

In some embodiments, the pump assembly 1 further comprises a micro-perforated plate 70, the micro-perforated plate 70 is disposed in the housing 10 and between at least one inner sidewall of the housing 10 and the booster pump 20, the micro-perforated plate 70 is spaced apart from the at least one inner sidewall to form an air layer, and a plurality of perforations are formed on the micro-perforated plate 70. The provision of the microperforated panel 70 allows a resonant sound-absorbing structure to be formed within the casing 10, effectively reducing the transmission of noise generated by the booster pump 20 to the outside of the casing 10, and reducing the noise of the pump assembly 1.

Further, the micro-perforated plate 70 is preferably made of a metal material, which has good heat dissipation performance, and can increase the heat dissipation efficiency, thereby improving the operation efficiency of the booster pump 20 and the user experience of the water purifier.

Specifically, the micro-perforated plate 70 may be fixed within the main casing 11, which is not disassembled together with the pre-assembly formed by the booster pump 20, the first elastic buffer member 30, and the second elastic buffer member 40.

In some embodiments, the main housing 11 and the cover 12 are made of metal material to form a metal sound-deadening chamber in the housing 10, which can isolate high-frequency noise and further reduce the noise of the pump assembly 1.

The present invention also provides a water purifier comprising the pump assembly 1 described in any of the above embodiments. The water purifier with the pump assembly 1 has the advantages of small vibration and low noise, and is convenient for the installation, the disassembly, the maintenance, the debugging and the replacement of the booster pump.
