The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

A pump mounting structure 100 according to an embodiment of the present invention is described in detail below with reference to fig. 1 to 9. The assembling structure may be formed at a mounting frame of a drinking water apparatus or a water purifying apparatus.

The pump assembling structure 100 includes: the shell 10 and the sound-absorbing interlayer 20 are installed. Wherein the pump is assembled on the mounting case 10, that is, the mounting case 10 provides a supporting structure of the pump, and the sound-absorbing interlayer 20 is mainly used for reducing the working noise of the pump.

I.e. the pump is embedded in the mounting cavity 11, in order to reduce the noise transmission, the mounting housing 10 may further include a cover plate 14 for closing the opening 111, thereby defining a closed cavity structure.

The sound-absorbing interlayer 20 is arranged on the inner wall of the installation cavity 11, and the sound-absorbing interlayer 20 is at least wrapped on one side of the pump. That is, the sound absorbing barrier 20 may wrap around one, both, or more than two sides of the pump. Wherein, inhale sound interlayer 20 and can include resonance sound absorbing structure and porous sound absorbing material combination and form, for example, inhale sound interlayer 20 and include a perforated plate resonance sound absorbing structure and set up the sound cotton of inhaling on the perforated plate. Like this, the through hole on the perforated plate and inhale the sound cotton all can subduct the noise. The sound wave passes the through hole on the perforated plate earlier at the transmission in-process, then passes the cotton micropore of sound absorption again, and the aperture of variation in size can subduct the noise of different frequencies, inhales the cotton viscous resistance that can produce moreover to the energy of consumption sound wave, and then improve the noise reduction effect who inhales sound interlayer 20. It is understood that the above description is merely illustrative and not restrictive of the embodiments of the present invention, and that the sound absorbing barrier 20 may also include other forms of sound absorbing structures, such as a thin film porous resonant sound absorbing structure, a porous absorbing structure such as fiberglass or fiber yarn.

In an alternative embodiment, the sound absorbing barrier 20 is wrapped around the circumference of the pump, i.e. the sound absorbing barrier 20 is wrapped around the circumference of the pump. In the case of a cylindrical pump, the cross-section of the sound-absorbing partition 20 may be circular, and in the case of a rectangular or square pump, the cross-section of the sound-absorbing partition 20 may be closed square.

In an alternative embodiment, the sound-absorbing barrier 20 extends a distance (e.g., the length of the sound-absorbing barrier 20 in the vertical direction in fig. 1) equal to the height of the pump, so that the operating noise of the pump can be better reduced. Further, the sound absorbing interlayer 20 is wrapped at least around the circumference of the motor of the pump.

In order to further improve the noise reduction capability of the sound absorbing interlayer 20, the sound absorbing interlayer 20 is spaced apart from the inner wall of the mounting cavity 11, thereby forming an air cavity 21. When the sound waves are conducted into the air cavity 21, the air in the air cavity 21 can absorb a part of the sound wave energy and can rebound a part of the sound waves, so that the working noise of the pump is effectively reduced.

In short, according to the utility model discloses pump assembly structure 100 inhales sound interlayer 20 through the inner wall setting at installation cavity 11 to thereby will inhale sound interlayer 20 and the inner wall interval setting of installation cavity 11 and establish out air chamber 21, so, make the operating noise of pump can pass through installation cavity 11, inhale sound interlayer 20 and air chamber 21 and make an uproar many times, thereby effectively reduce the operating noise of pump.

In some alternative embodiments of the present invention, as shown in fig. 1 in conjunction with fig. 3, the sound absorbing barrier 20 is spaced from the outer wall of the pump. That is, sound-absorbing interlayer 20 is separated from the outer wall of the pump, so that the working noise of the pump can be reduced in installation cavity 11, and the heat generated in the working process of the pump can be transferred to installation shell 10 through the cavity and dissipated outwards through installation shell 10. Therefore, the pump assembly structure 100 of the present application can reduce noise, and can also ensure heat dissipation performance of the pump, thereby prolonging the service life of the pump.

In some optional embodiments of the present invention, the sound-absorbing interlayer 20 is detachably connected to the inner wall of the installation cavity 11. Like this, the inner wall of installation cavity 11 can set up one or more than two sound-absorbing interlayer 20 as required, for example, in the lower condition of the operating noise of pump, can only set up one or two sound-absorbing interlayer 20, in the higher condition of the operating noise of pump, can set up two or more than two sound-absorbing interlayer 20, in the condition that installation cavity 11 is square chamber, a plurality of sound-absorbing interlayer 20 can set up on one of them internal face of installation cavity 11 or set up respectively on two or more than internal face. In the case where the mounting cavity 11 is a circular cavity, a plurality of sound absorbing interlayers 20 may be distributed with respect to the axial direction of the pump (e.g., the up-down direction in fig. 1).

In a preferred example, the installation cavity 11 is a square cavity, and at least two opposite inner wall surfaces of the installation cavity 11 are provided with the sound absorbing interlayer 20. That is, the sound-absorbing interlayer 20 is disposed on the left and right inner wall surfaces and/or the front and rear inner wall surfaces of the mounting cavity 11, so that sound waves can enter the sound-absorbing interlayer 20 and the air cavity 21 in the left and right directions or the front and rear directions, and a better noise reduction effect is achieved.

In an alternative example, as shown in fig. 1 and fig. 3, the pump is vertically assembled in the installation cavity 11, a support plate 12 is disposed on an inner wall of the installation cavity 11, an upper end of the sound-absorbing interlayer 20 abuts against a top wall of the installation cavity 11, and a lower end of the sound-absorbing interlayer 20 abuts against an upper surface of the support plate 12. Namely, the sound absorption interlayer 20 is clamped between the top wall of the mounting cavity 11 and the support plate 12, and the assembly and disassembly are convenient.

In a further optional example, the inner wall of the installation cavity 11 is further provided with a baffle 13, the baffle 13 abuts against the inner side of the sound absorption interlayer 20, and the outer side of the sound absorption interlayer 20 is provided with a limiting plate 22 extending along the horizontal direction. That is, the displacement of the sound-absorbing interlayer 20 in the horizontal direction is limited by the baffle 13, and the air chamber 21 is formed by spacing the sound-absorbing interlayer 20 from the inner wall of the installation chamber 11 by the limiting plate 22.

In other embodiments of the present invention, the pump assembly structure 100 further comprises: a damping pad 30. The damping pad 30 abuts at least one axial end of the pump. As can be understood by those skilled in the art, the pump body and the driving motor are respectively arranged on the axial direction of the pump, and when the driving motor works, vibration transmission in the axial direction can be generated, and resonance radiation noise is generated. In the case where the damping pad 30 is provided at the axial end of the pump, the damping pad 30 can be deformed to reduce the vibration amplitude of the pump, thereby reducing the resonance radiation noise of the pump.

In the case where the pump is vertically assembled in the mounting chamber 11, the vibration amplitude is larger at the axially lower end of the pump due to the influence of gravity, and therefore, it is preferable to provide the vibration-damping pad 30 at the axially lower end of the pump, and it is of course more preferable to provide the vibration-damping pads 30 at both the axially upper and lower ends of the pump.

In an alternative embodiment, as shown in fig. 6 in combination with fig. 4 and 5, the vibration damping pad 30 includes an abutting plate 31 and a shroud plate 32 provided around the abutting plate 31, and the shroud plate 32 surrounds both axial ends of the pump. That is, the bottom plate of the vibration damping pad 30 and the shroud plate 32 together form a receiving cavity open to one side, and the axial end of the pump is inserted into the receiving cavity, so that the vibration amplitude of the pump is reduced in the axial direction. Preferably, the axial both ends of pump all are equipped with the damping pad to make the axial both ends of pump all be restricted by damping pad 30, effectively reduce the vibration range of damping pad 30.

Further optionally, at least one side of the abutting plate 31 is provided with a buffer column 311. As shown in fig. 6 in conjunction with fig. 7 to 9, the upper side and/or the lower side of the abutting plate 31 may be provided with a cushion post 311, the cushion post 311 directly abuts on the pump when the cushion post 311 is located on the side facing the pump, and the cushion post 311 abuts on the inner wall surface of the mounting cavity 11 when the cushion post 311 is located on the side away from the pump. That is, in order to accommodate different vibration strengths of the pump, the vibration damping pads 30 are respectively provided with a damping structure in the axial direction. Generally, in the case where the vibration intensity of the pump is weak, the portion of the vibration damping pad 30 directly contacting the pump is deformed to reduce the vibration intensity of the pump; as the intensity of the pump vibrations increases, the vibration waves will be transmitted upward or upward in the axial direction, thereby acting on the other portions of the vibration damping pad 30. In other words, the structural design of the damping pad 30 of the present application has multi-stage damping capabilities.

In one embodiment, as shown in fig. 4 to 7, the damping pad 30 is provided with the damping columns 311 on both upper and lower sides thereof, and the damping columns 311 are located in different vertical directions. That is, the upper cushion column 311 of the cushion pad 30 is configured to have a first-stage damping structure, the contact plate 31 is configured to have a second-stage damping structure, and the lower cushion column 311 of the cushion pad 30 is configured to have a third-stage damping structure, so that when the pump is operated, the vibration wave is gradually transmitted upward or downward, thereby gradually absorbing the vibration energy of the pump. Of course, it is understood that the damping structure design of the damping pads 30 at both axial ends of the pump may be the same or different, and when the pump is vertically assembled, the vibration waves generated by the pump are more easily transmitted downward due to the influence of gravity, so that the damping pad 30 at the lower axial end of the pump may be designed as a two-stage or more damping structure, and the damping pad 30 at the upper axial end of the pump may be designed as a one-stage or more damping structure. In addition, in order to further enhance the vibration resistance of the vibration damping pad 30 as a whole, the buffer posts 311 located on the upper and lower sides of the abutting plate 31 may be disposed in a staggered manner in the vertical direction, so that the upper and lower concave-convex structures are formed on the vibration damping pad 30.
