Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

In accordance with one aspect of the present invention, as shown in fig. 1-3, a pump assembly 100 is provided. The pump assembly 100 includes a pump body 200, a damper spring 310, a connection assembly 320, and a holder 400. The pump main body 200 may be a main power source for providing pressure to raw water. The pump main body 200 may be a water pump or a booster pump, as required. The fixing base 400 may be a mounting base of the pump body 200, and the pump body 200 may be fixed to other objects through the fixing base 400. Taking the water purifier as an example, the fixing base 400 may be disposed on the water purifier (e.g., a base of the water purifier), so that the pump body 200 may be fixed in the water purifier through the fixing base 400. The damper spring 310 has opposite first and second ends 301 and 302 in an axial direction thereof. The first end 301 and the second end 302 of the shock absorbing spring 310 may change a distance therebetween according to a force condition. Wherein the first end 301 is connected to the pump body 200. The second end 302 is connected to the fixing base 400 through a connecting component 320. The damping spring 310 separates the pump body 200 from the holder 400. The connection assembly 320 may have any structure as long as it can connect the second end 302 of the damper spring 310 with the holder 400. The damping spring 310 and the fixing seat 400 may be connected by a snap, a rivet, or the like, or may be connected by an adhesive, or even by welding. In this way, the damping spring 310 is interposed between the pump body 200 and the fixing base 400, and absorbs vibration generated when the pump body 200 operates by compression and extension of the damping spring 310, thereby preventing the vibration from being transmitted to the fixing base 400 or preventing the pump body 200 from being in direct contact with the fixing base 400, thereby generating noise. The damping spring 310 may be one or more, and if the pump body 200 is spaced apart from the holder 400 by a plurality of damping springs 310, each damping spring 310 may be coupled to one coupling assembly 320.

With this arrangement, even if vibration is generated while the pump body 200 is operating, the vibration can be absorbed by the damper spring 310, and the damping spring 310 absorbs the vibration much more than an elastic pad such as a rubber pad, so that the vibration is not transmitted to the fixing base 400, thereby reducing noise generated by the vibration. Further, the damper spring 310 serves as a member for absorbing vibration, and thus not only can absorb vibration generated in the axial direction of the damper spring, but also can absorb vibration generated when the pump body 200 swings in the lateral direction, thereby protecting the pump body 200. Therefore, the vibration of the pump assembly 100 can be reduced through the damping spring 310, the noise is reduced, and the use experience of a user in the use process is improved.

Since the pump head of the pump main body 200 is generally complicated in structure, the water inlet/outlet port, the power supply port, and the like are generally provided on the pump head, and the external shape of the pump body is simple, it is preferable that the pump assembly includes a plurality of damper springs 310, and the plurality of damper springs 310 may be uniformly provided on both sides of the pump main body 200. Thus, the plurality of damping springs 310 may have a sufficient installation space, and the plurality of damping springs 310 may be uniformly disposed, so that the force applied to the fixing base 400 may be uniform, the vibration of the pump body 200 may be small, and the noise may be low.

Illustratively, the connection assembly 320 may include a liner 321 and a connector 322. The damping spring 310 is disposed on the lining member 321, and the lining member 321 is connected to the second end 302 of the damping spring 310. In one embodiment, the liner 321 may be coupled to the second end 302 of the damper spring 310 by interference fit of the bore shaft. The connecting member 322 connects the lining member 321 with the fixing base 400. In one embodiment, the connecting member 322 has a first position-limiting portion and a second position-limiting portion, at least a portion of the connecting member 322 passes through the through holes of the lining member 321 and the fixing base 400, and the lining member 321 and the fixing base 400 are clamped between the first position-limiting portion and the second position-limiting portion. A preferred embodiment of the connecting member 322 will also be described below. The first end 301 of the damping spring 310 is connected to the pump body 200, the second end 302 of the damping spring 310 is connected to the lining member 321, and the lining member 321 is connected to the fixing base 400 through the connecting member 322. The pump body 200 is coupled to the fixing base 400 in a layer-by-layer coupled relationship, and the damper spring 310 is disposed therebetween to absorb vibration generated from the pump body 200.

Since the second end 302 of the damping spring 310 is still in a spiral structure of the damping spring, the second end 302 is directly connected to the fixing base 400, which is inconvenient to process. Therefore, the connecting assembly 320 is arranged between the damping spring 310 and the fixing seat 400, so that the purposes of reducing the process difficulty and facilitating the assembly can be achieved. Moreover, by sleeving the damping spring 310 on the lining member 321, the lining member 321 can also guide the damping spring 310, so that the damping spring 310 mainly compresses or stretches along the axial direction thereof to absorb the vibration, thereby effectively preventing the transverse (perpendicular to the axial direction) swing of the pump body 200 during the operation process.

Illustratively, the connector 322 may comprise a threaded connector. Two ends of the threaded connection are respectively connected to the lining member 321 and the fixing seat 400. In one embodiment, the connector 322 may be a screw. The screw rod is rod-shaped, threads are respectively arranged at two ends of the screw rod, and the lining part 321 and the fixed seat 400 are respectively connected with the threads at the two ends, so that the function of connecting the lining part 321 and the fixed seat 400 can be achieved. The threaded connecting piece is a standard piece, can be widely purchased, and is simple to connect and easy to disassemble and assemble.

Further, the threaded connection may be a bolt 322 a. The lining member 321 has a through hole 321a provided in the axial direction. The inner diameter of the through hole 321a is smaller than the outer diameter of the head of the bolt 322 a. The bolt 322a is threaded to the fixing base 400 through the through hole 321 a. In one embodiment, the fixing base 400 may be provided with a thread, and the bolt 322a may be connected with the fixing base 400 through the thread. The lining member 321 is sandwiched between the head of the bolt 322a and the holder 400. The bolt 322a is gradually rotated to connect with the fixing seat 400, and the lining member 321 can be firmly connected with the fixing seat 400 by the pretightening force of the bolt 322a, so that the damping spring 310 also connects the pump body 200 with the fixing seat 400. The connecting piece 322 has simple structure and convenient assembly and disassembly.

Illustratively, the connection assembly 320 may also include a spacer 323. Washer 323 fits over bolt 322 a. A washer 323 is located between the head of the bolt 322a and the lining member 321. The inner diameter of the washer 323 is smaller than the outer diameter of the head of the bolt 322 a. The outer diameter of the washer 323 is smaller than the inner diameter of the damper spring 310. That is, the washer 323 does not press on the first end 301 of the damper spring 310, but may press on the connecting member 322 at the upper portion as shown in fig. 2 by the bolt 322 a.

The washer 323 serves to increase a contact area between the head of the bolt 322a and the connection member 322, thereby preventing the head of the bolt 322a from generating excessive pressure to the upper portion of the liner 321 and damaging the liner 321 when the damper spring 310 absorbs vibration.

In another embodiment, the holder 400 may be provided with a counterbore 401 on the surface facing away from the pump body 200. The counterbore 401 also includes a through bore extending through the holder 400. A nut 322b may be received in counterbore 401. The screw connector passes through the through hole of the fixing base 400 and is connected to the nut 322b to connect to the fixing base 400.

The counter bore 401 is arranged, so that the nut 322b can be conveniently installed in the counter bore, and the phenomenon that the nut 322b forms a bulge on the lower surface of the fixing seat 400 after installation to cause instability when the fixing seat 400 is placed is avoided. In addition, the nut 322b is connected with the threaded connector, so that the connector 322 and the fixing seat 400 are fixed, and the installation and the disassembly are convenient.

Illustratively, the second end 302 of the damper spring 310 may be secured with an annular clip 311. The outer peripheral wall of the lining member 321 is provided with an annular groove 321 b. The annular clamp 311 is disposed on the inner member 321 and is retained in the annular groove 321 b. The annular collar 311 may be welded or the like to the second end 302 of the damper spring 310 to form a single piece. The inner member 321 passes through the annular band 311 and is coupled to the annular band 311 through the annular groove 321b, thereby fixedly coupling the inner member 321 to the damper spring 310.

The inner liner 321 and the damper spring 310 having this arrangement are simple in structure, firmly attached, and also easily detached.

Illustratively, the lining member 321 may be an elastic member, that is, the lining member 321 inserted into the damper spring 310 may also absorb vibration. Since the pump body 200 generates not only vibration in a longitudinal direction (which is parallel to the axial direction of the damper spring 310) but also vibration in a lateral direction (which is perpendicular to the axial direction of the damper spring 310) when it is operated. The longitudinal vibration can be absorbed by the damping spring 310, and the damping spring 310 has a less than ideal energy absorbing effect for the transverse oscillation, and if the oscillation frequency is matched with the frequency of the pump body 200 itself, resonance can be generated, so that the oscillation amplitude is larger. The elastic lining member 321 is provided in the damper spring 310 to greatly absorb the lateral vibration, thereby reducing the possibility of noise generated from the pump assembly 100.

Illustratively, the pump assembly 100 further includes a housing (not shown). The housing may be connected to the holder 400. The pump body 200, the damper spring 310, and the connection assembly 320 may all be contained within the housing. When the damping spring 310 has the maximum deformation amount, there are gaps between the pump body 200 and the fixing base 400 and between the pump body 200 and the casing. Taking fig. 1 as an example, if the damping spring 310 reaches the maximum compression amount, the pump body 200 and the fixing seat 400 still have a gap. If the damping spring 310 reaches the maximum amount of tension, there is also a gap between the pump body 200 and the casing (the top surface of the casing may be above the pump body 200). The pump assembly 100 having this arrangement can limit the moving range of the pump body 200 by the amount of limit deformation of the damper spring 310, and prevent the pump body 200 from colliding with other parts to generate noise when the pump assembly 100 is in operation, which is simple and effective.
