Referring to fig. 1 and 2, fig. 1 is an isometric view of pump assembly 20 in some embodiments, and fig. 2 is a schematic view of pump assembly 20 secured to base 10 in some embodiments. The application provides a damping sleeve 210 can overlap and locate on pump body 220, plays vibration/noise reduction's effect to pump body 220, and damping sleeve 210 constitutes pump assembly 20 with pump body 220. The pump body 220 may be an air pump, a water pump, or other components that are prone to generate vibration and noise during operation, and of course, the damping sleeve 210 may also be used to damp and reduce noise of other components that are prone to generate vibration and noise during operation, such as a motor and an electric valve. In some embodiments, the shock absorbing sleeve 210 is applied to the toilet, for example, the shock absorbing sleeve 210 is used to fix the pump body 220 on the base 10 of the toilet and to absorb and reduce the shock and noise of the pump body 220. The base 10 may be a structure for carrying the pump body 220 of the toilet, for example, in some embodiments, the shock-absorbing sleeve 210 is used for shock-absorbing and noise-reducing functions for an air pump in a cleaning system (not shown) of the toilet, and the base 10 may be a structure for installing the cleaning system of the toilet.

Specifically, in some embodiments, the shock sleeve 210 includes a body 2110 and at least three connecting blocks 2120. The pump body 220 has two opposite end surfaces 2210 and a side surface (not labeled) located between the two end surfaces 2210, wherein the body 2110 is sleeved on the pump body 220 and covers the pump body 220 along the peripheral side, in other words, the projection of the body 2110 on the pump body 220 covers the side surface of the pump body 220. At least three attachment blocks 2120 are disposed at intervals on an outer wall 2111 of the body 2110, and the attachment blocks 2120 are attached to the base 10 and bear the weight of the body 2110 and the pump body 220. In other words, when the connecting block 2120 is fixedly connected to the base 10, the body 2110 and the pump body 220 are integrally suspended on the base 10, the body 2110 and the pump body 220 are not directly contacted with the base 10, and the shock absorbing sleeve 210 is contacted with the base 10 only through the connecting block 2120. At least two connecting blocks 2120 are spaced in the circumferential direction of the body 2110 to limit at least two positions of the body 2110 in the circumferential direction. Also, geometric centers of at least three connecting pieces 2120 are located on the same plane to suppress vibration of the body 2110 in a direction perpendicular to the plane.

The shock-absorbing sleeve 210 and the connecting block 2120 are arranged so that the body 2110 and the pump body 220 form a whole body which is suspended on the base 10, and therefore shock generated by the pump body 220 is not easy to transmit to the base 10, and a good shock-absorbing effect is achieved. Meanwhile, at least two connecting blocks 2120 are spaced in the circumferential direction of the body 2110, and the geometric centers of at least three connecting blocks 2120 are located on the same plane, so that the whole body formed by the body 2110 and the pump body 220 can be restrained from vibrating in the direction perpendicular to the plane, and the shock absorption effect can be further improved. In addition, since the body 2110 covers the pump body 220 along the circumferential side of the pump body 220, noise generated by the pump body 220 is less likely to penetrate through the body 2110, and a good noise reduction effect can be achieved. Thus, the damper sleeve 210 has good damping and noise reduction performance.

It is understood that the specific shapes of the body 2110 and the pump body 220 are not limited, and the shape of the body 2110 may be adaptively adjusted according to the shape of the pump body 220 to cover the side of the pump body 220. For example, in some embodiments, the pump body 220 is generally cylindrical in shape, with the sides of the pump body 220 connecting the edges of the two end surfaces 2210, respectively. The main body 2110 may be correspondingly configured as a hollow cylinder with two open ends, the main body 2110 has an inner wall surface facing the pump body 220 and an outer wall surface 2111 facing away from the pump body 220, the inner wall surface of the main body 2110 may directly abut against a side surface of the pump body 220, and a buffer structure such as sponge and rubber may be further disposed between the inner wall surface of the main body 2110 and the side surface of the pump body 220, so as to further improve the damping and noise reduction effects of the damping sleeve 210. Of course, the pump body 220 may also be substantially square, conical or any irregular shape, and the side surface of the pump body 220 and the end surface 2210 may be connected by other surfaces, as long as the shape of the body 2110 can be adapted to the shape of the pump body 220, so that the projection of the body 2110 on the pump body 220 covers the side surface of the pump body 220.

Further, referring to fig. 1 and 3 together, fig. 3 is a bottom view of pump assembly 20 in some embodiments. In some embodiments, at least three attachment blocks 2120 are provided at intervals along the circumference of the body 2110 to fix a plurality of locations on the circumference of the body 2110. For example, in some embodiments, three connecting blocks 2120 are disposed on the outer wall 2111 of the body 2110, the three connecting blocks 2120 are spaced along the circumferential direction of the body 2110, and the positions of the three connecting blocks 2120 in the axial direction of the body 2110 correspond, in other words, the axis of the body 2110 is perpendicular to the plane of the geometric centers of the three connecting blocks 2120. Specifically, the plane of the geometric centers of the three connecting blocks 2120 may be parallel to the horizontal plane, and the body 2110 extends in the vertical direction.

Further, in some embodiments, the connecting blocks 2120 are uniformly distributed along the circumferential direction of the main body 2110, so that the main body 2110 is stressed more uniformly and is not prone to swing in a certain direction due to uneven stress, and therefore the vibration damping effect is further improved. Referring to fig. 3, in some embodiments, three connecting blocks 2120 are uniformly distributed along the circumferential direction of the body 2110, so that a good fixing and vibration damping effect can be achieved with a small number of connecting blocks 2120, and the installation cost of the damping sleeve 210 can be reduced.

Referring to FIG. 4, FIG. 4 is an isometric view of a pump assembly 20 in accordance with further embodiments. In other embodiments, at least three attachment blocks 2120 are disposed on opposite sides of the body 2110, for example, a plane in which the geometric centers of the attachment blocks 2120 lie passes through the axis of the body 2110. It will be appreciated that in this embodiment, at least one of the sides of the body 2110 is provided with at least two attachment blocks 2120. In some embodiments, attachment blocks 2120 located on the same side of the body 2110 are spaced circumferentially of the body 2110. Thus, the attachment block 2120 can fix different portions of the body 2110 on both sides of the body 2110, thereby suppressing vibration of the body 2110 in a direction perpendicular to the axial direction. In this embodiment, the plane of the geometric centers of the connecting blocks 2120 may be parallel to the horizontal plane, and the main body 2110 extends in the horizontal direction. Further, in this embodiment, all the connecting blocks 2120 are uniformly distributed along the axial direction of the main body 2110, so that the main body 2110 is stressed more uniformly everywhere, and is not easy to swing towards a certain direction due to uneven stress, and the vibration damping effect is further improved.

Referring to fig. 1 and fig. 2 again, in some embodiments, the damping sleeve 210 further includes two fixing portions 2130, where the two fixing portions 2130 connect two ends of the body 2110 and limit the pump body 220 at two opposite end surfaces 2210 of the pump body 220. In some embodiments, a projection of one of the fixing portions 2130 on the pump body 220 covers one end surface 2210 of the pump body 220, or projections of two fixing portions 2130 on the pump body 220 cover two end surfaces 2210 of the pump body 220, respectively, so as to further mask noise generated by the pump body 220 and improve noise reduction effect of the damping sleeve 210. It is to be understood that, in the embodiment shown in fig. 1 and 3, one of the fixing portions 2130 covers only the edge region of the end surface 2210 of the pump body 220, and the other fixing portion 2130 covers the end surface 2210 of the pump body 220. In other embodiments, when the fixing portion 2130 covers the two end surfaces 2210 of the pump body 220, the whole of the fixing portion 2130 and the body 2110 may be substantially a hollow cylinder.

Of course, in the present application, it is described that the body 2110 or the fixing portion 2130 covers a certain surface of the pump body 220, and it is not meant that the body 2110 or the fixing portion 2130 completely covers the surface of the pump body 220, and in some embodiments, the body 2110 or the fixing portion 2130 may also be provided with a groove structure or a port structure to enable communication between the pump body 220 and the outside. For example, in some embodiments, the body 2110 is provided with an air inlet 2112 extending through the body 2110 to provide air communication between the pump body 220 and the environment. One of the fixing portions 2130 is provided with a wire passing hole 2131 penetrating through the fixing portion 2130, so that the fixing portion 2130 is electrically connected with other elements through a lead wire passing through the wire passing hole 2131. In addition, in the embodiment shown in fig. 1, the fixing portion 2130 on one side covers only the edge area of the end surface 2210 of the pump body 220, and the air outlet 2211 of the pump body 220 is exposed to the air from between the end portions. In other embodiments, the fixing portion 2130 may cover the end surface 2210, and the fixing portion 2130 may have an air outlet penetrating through the fixing portion 2130 to achieve the air communication between the pump body 220 and the outside with the air inlet 2112.

Referring to fig. 2 and 5, fig. 5 is a schematic structural view of a pump assembly 20 according to yet another embodiment. In still other embodiments, the body 2110 can be further provided with a drain 2113 extending through the body 2110 so that fluid within the damping sleeve 210 can drain from the drain 2113. Specifically, the drain 2113 may be disposed at an end of the main body 2110 near the base 10, for example, at an end of the main body 2110 which is vertically downward, so that the liquid in the damping sleeve 210 can be drained from the drain 2113 after flowing in the vertically downward direction. In some embodiments, the body 2110 is provided with a plurality of circumferentially spaced drainage slots 2113 so that fluid from various locations within the shock absorbing sleeve 210 can drain from the drainage slots 2113 to avoid damaging the pump body 220. The plurality of water discharge grooves 2113 may be uniformly distributed or irregularly distributed in the circumferential direction of the body 2110.

In some embodiments, the damping sleeve 210 further includes a plurality of reinforcing ribs 2140, the reinforcing ribs 2140 fixedly connect the main body 2110 and the connecting block 2120, and the size of the reinforcing ribs 2140 in the axial direction of the main body 2110 is larger than that of the connecting block 2120 in the axial direction of the main body 2110. The reinforcing rib 2140 is provided to improve the coupling strength between the connecting block 2120 and the body 2110, thereby improving the structural strength of the damping sleeve 210 and preventing the connecting block 2120 from being damaged due to excessive load. Specifically, each connecting block 2120 may be correspondingly provided with one reinforcing rib 2140, or may be correspondingly provided with two reinforcing ribs 2140, and the two reinforcing ribs 2140 are respectively disposed on two sides of the connecting block 2120, so as to further improve the connection strength between the connecting block 2120 and the main body 2110.

Referring to fig. 1 again, the arrangement and material of each structure of the damping sleeve 210 are not limited, and specifically, any one of the main body 2110, the connecting block 2120, the fixing portion 2130 and the reinforcing rib 2140 that are connected to each other may be integrally formed, or may be connected to each other by way of screwing, welding or fastening. The material of the shock-absorbing sleeve 210 includes, but is not limited to, any suitable material with shock-absorbing function and sufficient structural strength, such as rubber and cotton. It should be noted that the material of the reinforcing rib 2140 may be the same as or different from the main body 2110 and the connecting block 2120. For example, in some embodiments, the main body 2110 and the connecting block 2120 are integrally formed by rubber, and the reinforcing rib 2140 is made of plastic or metal with hardness greater than that of rubber, so as to further enhance the structural strength of the damping sleeve 210 while achieving the damping and noise reducing effects.

The present application further provides a pump assembly 20, which includes a pump body 220 and a damping sleeve 210 as described in any of the above embodiments, wherein the damping sleeve 210 is sleeved on the pump body 220 and is used to connect to the base 10, so as to mount the pump body 220 on the base 10. The body 2110 limits the pump body 220 from the peripheral side, and the two fixing portions 2130 limit the pump body 220 from the opposite ends of the pump body 220, so that the shock-absorbing sleeve 210 and the pump body 220 are fixed relatively. Of course, in other embodiments, the damping sleeve 210 may not be provided with the fixing portion 2130, and the inner wall surface of the main body 2110 may be provided with a fixing structure that is in a snap fit or interference fit with the pump body 220, so as to achieve the fixed connection between the damping sleeve 210 and the pump body 220.

Referring again to fig. 1 and 2, the present application also provides a toilet including a base 10 and a pump assembly 20 as described above in any of the embodiments. The base 10 comprises a base body 110 and at least three assembling structures 120 arranged on the base body 110, the assembling structures 120 correspond to the connecting blocks 2120 of the shock-absorbing sleeve 210 one by one, and each assembling structure 120 is fixedly connected with one corresponding connecting block 2120, so that the whole body 2110 and the pump body 220 are arranged on the base body 110 in a hanging mode. Of course, the base 10 of the toilet is only illustrated in the embodiment shown in fig. 2, and actually, the toilet may further include other structures such as a urinal and a water tank, which are not described in detail herein.

Further, in some embodiments, the plane in which the geometric centers of the at least three connecting blocks 2120 lie passes through the center of gravity of the pump assembly 20. Specifically, in some embodiments, the center of gravity of the pump assembly 20 coincides with the center of gravity of the body 2110, the fixing portion 2130, and the pump body 220, and the plane in which the geometric centers of the at least three connecting blocks 2120 lie passes through the center of gravity of the body 2110, the fixing portion 2130, and the pump body 220. In this way, the plurality of connecting blocks 2120 can fix the body 2110, the fixing portion 2130 and the pump body 220 around the center of gravity of the whole body formed by the body 2110, the fixing portion 2130 and the pump body 220, so that vibration of the body 2110 and the pump body 220 is further suppressed, the body 2110 and the pump body 220 are prevented from swinging in one direction due to uneven stress, and the vibration damping effect of the damper housing 210 is further improved.

It should be noted that, in the present application, the vertical direction, the horizontal direction and the center of gravity of the damping sleeve 210 are described, and all of them can be understood as the vertical direction, the horizontal direction and the center of gravity in a state where the pump body 220 is mounted on the base 10 and can normally operate. In other words, in the present application, the arrangement of the damping sleeve 210 in the vertical direction or the horizontal direction, and the arrangement of the connecting block 2120 relative to the center of gravity of the damping sleeve 210 are described, which can be understood as the limitation of the damping sleeve 210 in the state that the pump body 220 is completely installed on the base 10 and can normally operate, but not the limitation of the damping sleeve 210 in the production, storage or transportation process.

The connection manner of the base 10 and the connection block 2120 is also not limited, and in some embodiments, the assembling structure 120 is a cylindrical structure disposed on the base 110, and the assembling structure 120 and the connection block 2120 may be fixedly connected by a threaded connection, a snap connection, a welding, an interference fit, or the like. It should be noted that the base 10 and the connecting block 2120 may be formed by an integral molding process. For example, if the connecting block 2120 is integrally formed on the base 10 and then the body 2110 of the damper sleeve 210 is connected to the connecting block 2120, or the damper sleeve 210 is integrally formed with the base 10 and then the pump body 220 is disposed in the damper sleeve 210, the material of the damper sleeve 210 may have elasticity so that the damper sleeve 210 can be fitted on the pump body 220.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
