Description

TECHNICAL FIELD

[0001] The present application relates to the field of booster pumps, in particular to a RO pump with elastic damping structure. BACKGROUND

[0002] The RO pump is a booster pump for a reverse osmosis system, mainly used in water purifiers to provide the required water pressure and water flow, so as to ensure that the system can produce pure water. When installing the RO pump, the RO pump is usually installed on a damping structure to reduce the vibration of the RO pump during operation and the noise caused by the vibration. The existing RO pump damping structure is usually a spring damping structure. For the related technology in the above, the inventor believes that it is necessary to provide a RO pump with another elastic damping structure for reducing the vibration of the RO pump during operation and the noise caused by the vibration. SUMMARY

[0003] In order to reduce the vibration of the RO pump during operation and the noise caused by the vibration, the present application provides a RO pump with elastic damping structure.

[0004] The RO pump with elastic damping structure provided by the present application adopts the following technical scheme:

[0005] A RO pump with elastic damping structure, comprising a mounting rack for installation in a water purifier and a RO pump body mounted on the mounting rack; the mounting rack comprises a mounting plate and at least three elastic damping members for supporting the mounting plate and the water purifier shell; the mounting plate has an arrangement through hole for arranging the elastic damping members, the elastic damping members comprise a damping part supported on the bottom surface of the mounting plate, a locking part supported on the top surface of the mounting plate, and a connecting part connecting the damping part and the locking part and arranged in the arrangement through hole; the elastic damping member has a mounting through hole penetrating the upper and lower surfaces; the bottom surface of the damping part is circumferentially spaced apart from the axis of the mounting through hole and has a deformation slot.

[0006] By adopting the above technical scheme, during the installation of the RO pump, the RO pump body is first installed in the mounting rack, and the RO pump is installed in the water purifier shell through the elastic damping members in the mounting rack. The arrangement of the elastic damping members on the mounting plate, due to the arrangement of the deformation slot in the damping part of the elastic damping member, enables the damping part to deform when subjected to force, thereby absorbing and weakening the vibration and noise caused by the vibration during the operation of the RO pump, which helps to prolong the service life of the RO pump.

[0007] Optionally, the damping part has a first damping ring part, a second damping ring part connected to the bottom surface of the first damping ring part, and a third damping ring part connected to the bottom surface of the second damping ring part, the outer diameter of the first damping ring part is greater than the outer diameter of the second damping ring part, and the outer diameter of the second damping ring part is greater than the outer diameter of the third damping ring part.

[0008] By adopting the technical scheme, the structure of the damping part is disclosed, and because the outer diameter of the damping part decreases in the direction from the first damping ring part to the third damping ring part, the damping part has two continuous stepped structures, which helps to improve the structural strength of the damping part.

[0009] Optionally, the outer surface of the third damping ring part has a first arc surface corresponding to the deformation channel and a second arc surface connecting adjacent two first arc surfaces.

[0010] By adopting the technical scheme, the first arc surface on the third damping ring part helps to improve the structural strength of the third damping ring part at the deformation channel and reduce the probability of damage of the third damping ring part during use.

[0011] Optionally, the elastic damping piece is arranged with an anti-abrasion protrusion on the top surface of the locking part, and the anti-abrasion protrusion is arranged in a uniform and spaced manner around the axis of the mounting through hole.

[0012] By adopting the technical scheme, the anti-abrasion protrusion is arranged on the top surface of the locking part, and the anti-abrasion protrusion is arranged in a uniform and spaced manner around the axis of the mounting through hole, so that when the screw is mounted in the mounting through hole, the probability of the screw abrading the top surface of the locking part of the elastic damping piece is reduced, and the stress on the top surface of the locking part is more uniform, which helps to prolong the service life of the elastic damping piece.

[0013] Optionally, the top surface of the anti-abrasion protrusion has an abutting flat surface.

[0014] By adopting the technical scheme, the abutting flat surface of the top surface of the anti-abrasion protrusion helps to increase the contact area between the anti-abrasion protrusion and the bottom surface of the head of the screw, so that the stress on the anti-abrasion protrusion is more uniform, and the probability of abrasion of the anti-abrasion protrusion is reduced.

[0015] Optionally, the mounting plate is provided with a locking through hole for the RO pump body to pass through, and the mounting plate is provided with a mounting piece at the edge of the locking through hole for connecting with the shell of the RO pump body.

[0016] By adopting the technical scheme, the mounting piece arranged circumferentially at the edge of the locking through hole of the mounting plate enables the mounting plate and the RO pump body to be stably matched, and reduces the probability of loosening of the RO pump body during operation.

[0017] Optionally, the mounting plate is provided with three circumferentially uniformly spaced mounting members.

[0018] Optionally, the mounting member comprises a first mounting piece connected to the mounting plate and a second mounting piece connected to the first mounting piece and extending upwardly, the second mounting piece having a threaded hole, and the mounting plate is fixed to the RO pump body by a screw.

[0019] By adopting the above technical scheme, the structure of the mounting member is disclosed, and through the cooperation between the first mounting piece and the second mounting piece, the upward extension of the second mounting piece helps to increase the contact area between the second mounting piece and the RO pump body, thereby improving the stability of the connection between the mounting plate and the RO pump body and reducing the probability of loosening of the RO pump body during operation.

[0020] Optionally, structure grooves are formed on both sides of the mounting member.

[0021] By adopting the above technical scheme, the structure grooves on the mounting plate help the mounting member to deform, thereby improving the tightness of the connection between the elastic member and the RO pump body and reducing the probability of breakage of the mounting plate.

[0022] Optionally, nine deformation grooves are circumferentially uniformly spaced on the bottom surface of the damping part.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] 1. An RO pump with an elastic damping structure, in the installation process of the RO pump, the RO pump body is mounted on the mounting plate, and the elastic damping member on the mounting plate allows the RO pump body to cooperate with the water purifier shell. Since the deformation grooves are circumferentially spaced around the axis of the mounting hole in the damping part of the elastic damping member, the vibration generated during the operation of the RO pump and the noise generated by the vibration can be absorbed and weakened.

[0025] 2. The circumferentially spaced anti-wear protrusions on the top surface of the support ring part help to reduce the probability of wear of the end surface of the support ring part and prolong the service life of the elastic damping member.

[0026] 3. The mounting member and structure groove on the mounting plate help to improve the stability of the connection between the mounting plate and the RO pump body and reduce the probability of loosening of the RO pump body during operation. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0033] The following will be described in detail in combination with the accompanying drawings. Figures 1-5 The present application will be further described in detail.

[0034] The embodiment of the present application discloses an RO pump with elastic damping structure. Referring to Figure 1 and Figure 2 , an RO pump with elastic damping structure comprises a mounting frame 1 for mounting in a water purifier and an RO pump body 2 mounted on the mounting frame 1. The RO pump body 2 comprises an upper pump body 21 and a lower pump body 22, and the mounting frame 1 is arranged in the upper pump body 21 close to one side of the lower pump body 22. Among them, the mounting frame 1 comprises a mounting plate 11 and four elastic damping members 3 for supporting the mounting plate 11 and the shell of the water purifier, and the mounting plate 11 has an arrangement through hole 111 for arranging the elastic damping member 3. In this embodiment, the elastic damping member 3 is a damping member of rubber material, the mounting plate 11 is a metal plate of cuboid, and the four elastic damping members 3 are arranged at the four corners of the mounting plate 11.

[0035] Referring to Figure 2 and Figure 3The elastic damping member 3 has a mounting hole 31 for arranging a screw, which penetrates the upper and lower surfaces of the elastic damping member 3. The elastic damping member 3 comprises a damping portion 32 supported on the bottom surface of the mounting plate 11, a locking portion 33 supported on the top surface of the mounting plate 11, and a connecting portion 34 connecting the damping portion 32 and the locking portion 33 and arranged in the arranging hole 111. The damping portion 32 has a first damping ring portion 321, a second damping ring portion 322 connected to the bottom surface of the first damping ring portion 321, and a third damping ring portion 323 connected to the bottom surface of the second damping ring portion 322. The outer diameter of the damping portion 32 gradually decreases from the first damping ring portion 321 to the third damping ring portion 323, thereby forming two continuous stepped structures.

[0036] Referring to Figure 2 and Figure 3 The bottom surface of the damping portion 32 is circumferentially spaced apart from the axis of the mounting hole 31 and has a deformation groove 324. The cross section of the deformation groove 324 is circular, and the deformation groove 324 penetrates the second damping ring portion 322 and the third damping ring portion 323. The outer surface of the third damping ring portion 323 has a first arc surface 3231 corresponding to the deformation groove 324 and a second arc surface connecting adjacent two first arc surfaces 3231, so as to improve the structural strength of the third damping ring portion 323 at the deformation groove 324. The number of the deformation grooves 324 is nine, and the nine deformation grooves 324 are uniformly spaced apart circumferentially about the axis of the mounting hole 31. The axis of the deformation groove 324 coincides with the axis of the first arc surface 3231. In the embodiment, the diameter of the mounting hole 31 is 6 mm, and the diameter of the deformation groove 324 is 2.8 mm.

[0037] Referring to Figure 4 The top surface of the elastic damping member 3 further has a plurality of wear-resistant protrusions 331 at the locking portion 33. The wear-resistant protrusions 331 are hemispherical, and the plurality of wear-resistant protrusions 331 are uniformly spaced apart circumferentially about the axis of the mounting hole 31. The top surface of the wear-resistant protrusion 331 has an abutting plane 3311 matched with the screw. In order to improve the connection strength between the wear-resistant protrusion 331 and the locking portion 33 of the elastic damping member 3, the connection between the wear-resistant protrusion 331 and the top surface of the locking portion 33 has a circular arc corner 3312. In the embodiment, the number of the wear-resistant protrusions 331 on the top surface of the locking portion 33 is nine.

[0038] Referring to Figure 1 and Figure 5The mounting plate 11 defines a locking hole 112 for the RO pump body 2 to pass through, and mounting members 113 are evenly spaced circumferentially around the edges of the locking hole 112. The mounting members 113 include a first mounting tab 1131 connected to the mounting plate 11 and a second mounting tab 1132 connected to the first mounting tab 1131 and extending upward. The second mounting tab 1132 has threaded holes extending through its front and rear sides. The upper pump body 21 of the RO pump has corresponding threaded holes. The mounting plate 11 is secured to the upper pump body 21 of the RO pump body 2 by screws. To reduce the risk of screw wear on the second mounting plate 11, rubber washers 1133 are installed in the threaded holes of the second mounting plate 11, blocking the second mounting holes from the screw caps. To facilitate deformation of the mounting members 113 and ensure a more secure fit within the upper pump body 21 of the RO pump body 2, the mounting plate 11 defines structural grooves 114 on either side of the mounting member 113. In this embodiment, the number of the mounting members 113 is three.

[0039] The implementation principle of an RO pump with an elastic shock-absorbing structure in the embodiment of the present application is as follows: during the installation process of the RO pump, the RO pump body 2 is first passed through the locking through-hole 112 in the mounting plate 11 and fixed to the mounting plate 11 by screws. Then, the elastic shock-absorbing member 3 installed on the mounting plate 11 is connected and matched with the housing of the water purifier. Because the vibration-absorbing portion 32 of the elastic shock-absorbing member 3 has deformable through-grooves 324 arranged at uniform intervals circumferentially with the axis of the mounting through-hole 31 as the axis, the elastic shock-absorbing member 3 can deform when subjected to vibration, thereby absorbing and reducing the vibration of the RO pump during operation and the noise generated by the vibration. The top surface of the locking portion 33 of the elastic shock-absorbing member 3 is also provided with anti-wear protrusions 331. Several anti-wear protrusions 331 are evenly arranged on the top surface of the locking portion 33 with the axis of the mounting through-hole 31 as the axis, thereby helping to reduce the probability of wear of the locking portion 33 of the elastic shock-absorbing member 3 and improving the service life of the elastic shock-absorbing member 3.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
