[0046] The embodiment provides a vibration reduction and noise reduction structure 1000, which is applied to a surface cleaning device, wherein the surface cleaning device may be a sweeper, a floor scrubber, a desktop cleaning robot, a window cleaning robot, or the like.

[0047] like Figure 1 and Figure 2 As shown, the vibration reduction and noise reduction structure 1000 includes a mounting base 100, an assembly set 200 and a driving member 400. The assembly set 200 is connected to the mounting base 100. The assembly set 200 includes a plurality of enclosure plates 210, and the plurality of enclosure plates 210 cooperate to enclose a receiving cavity 201. The driving member 400 is assembled in the receiving cavity 201. In some embodiments, the mounting base 100 can be a housing in a surface cleaning device. The driving member 400 can be a peristaltic pump in a surface cleaning device.

[0048] In other embodiments, the mounting base 100 may be a support base or other structure in a surface cleaning device. The driving member 400 may also be a power structure such as a motor or other power structure in a surface cleaning device.

[0049] Combined with Figure 3 and Figure 4, an elastic member 300 is protrudingly provided on one side of at least one enclosure plate 210 away from the accommodating cavity 201. One end of the elastic member 300 abuts against the enclosure plate 210 at its own location, and the other end of the elastic member 300 abuts against the mounting base 100. On the one hand, the enclosure plate 210 indirectly contacts the mounting base 100 through the elastic member 300, which can avoid direct contact of a large area of ​​the enclosure plate 210 at the location of the elastic member 300 with the mounting base 100, thereby reducing the contact area between the enclosure plate 210 at the location of the elastic member 300 and the mounting base 100, thereby reducing the resonance effect between the driving member 400 and the mounting base 100, and achieving the effect of damping and noise reduction. On the other hand, the elastic member 300 can play a buffering role between the enclosure plate 210 and the mounting base 100 at its own location, realize soft contact between the assembly sleeve 200 and the mounting base 100, and then realize a buffering effect between the driving member 400 and the mounting base 100, reduce the resonance between the driving member 400 and the mounting base 100, and further realize the effect of damping and reducing noise. Accordingly, the damping and reducing noise structure 1000 provided in the present application can also realize the noise reduction of the surface cleaning equipment and improve the user experience.

[0050] like Figure 3 and Figure 4 As shown, the assembly kit 200 includes a first enclosed plate 211, a second enclosed plate 212, a third enclosed plate 213, a fourth enclosed plate 214 and a top plate 230. The first enclosed plate 211 is located below the driving member 400 in the direction of gravity. The top plate 230 is spaced apart from the first enclosed plate 211. The third enclosed plate 213 and the fourth enclosed plate 214 are both connected between the first enclosed plate 211 and the top plate 230, and the third enclosed plate 213 and the fourth enclosed plate 214 are spaced apart from each other. Along the axial direction of the driving member 400, the second enclosed plate 212 is located at one end of the accommodating chamber 201, and is respectively connected with the first enclosed plate 211, the third enclosed plate 213 and the fourth enclosed plate 214. The end of the accommodating chamber 201 opposite to the second enclosed plate 212 is an opening structure 202, which can be used to connect the driving member 400 with other structures in the surface cleaning device. The axial direction of the driving member 400 may refer to the extending direction of the axis L.

[0051] It can be understood that the inner walls of each enclosure plate 210 and the top plate 230 close to the accommodating cavity 201 are in close contact with the driving member 400 , so that the assembly set 200 and the driving member 400 can be relatively fixed.

[0052] Combined with Figure 1 and Figure 2The end of the assembly sleeve 200 away from the second enclosure plate 212 is provided with a limit block 220, and the limit block 220 protrudes relative to the radial direction of the opening structure 202. The radial direction of the opening structure 202 may refer to any direction perpendicular to the axial direction of the driving member 400. The limit block 220 abuts against the end of the driving member 400 away from the second enclosure plate 212. Thus, the driving member 400 can be limited in the accommodating cavity 201 of the assembly sleeve 200.

[0053] like Figures 3 to 5 As shown, in some embodiments, the top plate 230, the third enclosure plate 213 and the fourth enclosure plate 214 are all provided with gaps at one end close to the second enclosure plate 212 and are interconnected. Thus, the end of the driving member 400 close to the second enclosure plate 212 can be exposed relative to the assembly set 200 so as to be connected to other structures in the surface cleaning device.

[0054] In some embodiments, the assembly sleeve 200 may be made of silicone. Accordingly, the assembly sleeve 200 has a certain elasticity and can absorb a portion of the vibration generated by the driving member 400, thereby achieving a buffering and shock absorbing effect.

[0055] In other embodiments, the mounting sleeve 200 may also be made of flexible materials such as rubber.

[0056] Of course, in other embodiments, the assembly kit 200 is not excluded from being made of relatively hard materials such as plastic.

[0057] like Figure 3 to Figure 4 as well as Figure 6 As shown, in some embodiments, the driving member 400 includes a primary vibration source 410 and a secondary vibration source 420. It is understandable that the driving member 400 includes a driver and a pump head, wherein the driver is the primary vibration source 410 and generates a larger vibration. The pump head is the secondary vibration source and generates a relatively smaller vibration. The primary vibration source 410 can be disposed near one end of the opening structure 202 of the accommodating chamber 201.

[0058] A plurality of first elastic members 310 and a plurality of second elastic members 320 are protruding from one side of the first enclosure plate 211 away from the accommodating cavity 201. The plurality of first elastic members 310 are located below the main vibration source 410 in the direction of gravity and are evenly distributed. The plurality of second elastic members 320 are located below the secondary vibration source 420 in the direction of gravity and are evenly distributed. Among them, the elastic performance of the first elastic member 310 is better than the elastic performance of the second elastic member 320. Thus, the first elastic member 310 can provide a greater buffering effect for the location of the main vibration source 410, reduce the generation of resonance, and achieve noise reduction. In the embodiment, the positions of the first elastic member 310 and the second elastic member 320 are reasonably arranged to ensure that an effective and reliable buffering effect is provided between the driving member 400 and the mounting base 100, while also reducing cost investment.

[0059] In other embodiments, the plurality of first elastic members 310 may be distributed non-uniformly and / or the plurality of second elastic members 320 may be distributed non-uniformly.

[0060] In other embodiments, a plurality of first elastic members 310 or a plurality of second elastic members 320 are protruding from one side of the first enclosing plate 211 away from the accommodating cavity 201. The plurality of first elastic members 310 or a plurality of second elastic members 320 are distributed uniformly or non-uniformly below the driving member 400 in the direction of gravity.

[0061] like Figure 4 and Figure 5 As shown, in some embodiments, the first elastic member 310 and the second elastic member 320 are both flexible column structures made of silicone, and are both integrally formed with the assembly sleeve 200, that is, the first elastic member 310, the second elastic member 320 and the assembly sleeve 200 can be formed by integral injection molding. The first elastic member 310 and the second elastic member 320 can provide a good buffering effect, absorb the vibration energy generated by the driving member 400, and also reduce the material and assembly costs.

[0062] In other embodiments, the first elastic member 310 and the second elastic member 320 may also be separate structures from the assembly kit 200, and are fixedly connected to the first enclosure plate 211 by bonding or other methods.

[0063] In some embodiments, the first elastic member 310 may be a cylindrical structure, a quadrangular prism structure, a pentagonal prism structure, or the like.

[0064] In some embodiments, the second elastic member 320 may also be a cylindrical structure, a quadrangular prism structure, a pentagonal prism structure, or the like.

[0065] In the embodiment, the diameter d1 of the first elastic member 310 is greater than the diameter d2 of the second elastic member 320, and the height h1 of the first elastic member 310 is greater than the height h2 of the second elastic member 320. When the first elastic member 310 and the second elastic member 320 are multi-prism structures, the diameter d1 of the first elastic member 310 and the diameter d2 of the second elastic member 320 both refer to the diameter of the circumscribed circle thereof. Accordingly, compared with the second elastic member 320, the first elastic member 310 can have a greater degree of deformability, that is, has better elastic performance, and can better absorb the vibration caused by the main vibration source 410 in the driving member 400.

[0066] In other embodiments, the first elastic member 310 and / or the second elastic member 320 may also be elastic structures such as springs or spring sheets.

[0067] Of course, in other embodiments, the first elastic member 310 and / or the second elastic member 320 are not excluded from being configured as bone structures made of flexible materials.

[0068] like Figure 4 and Figure 5 As shown, in the embodiment, a sink groove 2111 is provided on one side of the first enclosure plate 211 away from the accommodating cavity 201, and is located below the gravity direction of the main vibration source 410. Accordingly, the first elastic member 310 is disposed in the sink groove 2111. When both the first elastic member 310 and the second elastic member 320 are not subjected to force, the end surface of the first elastic member 310 away from one end of the first enclosure plate 211 is flush with the end surface of the second elastic member 320 away from one end of the first enclosure plate 211, so that the assembly kit 200 can be stably placed on the mounting base 100, and the driving member 400 can also be stably installed on the mounting base 100.

[0069] like Figure 3 and Figure 4 As shown, a plurality of third elastic members 330 are protrudingly provided on one side of the second enclosing plate 212 away from the accommodating cavity 201, and the plurality of third elastic members 330 are evenly spaced in a direction perpendicular to the axial direction of the driving member 400 and parallel to the first enclosing plate 211. A plurality of fourth elastic members 340 are protrudingly provided on one side of the third enclosing plate 213 away from the accommodating cavity 201, and the plurality of fourth elastic members 340 are evenly spaced in the axial direction of the driving member 400. A plurality of fifth elastic members 350 are protrudingly provided on one side of the fourth enclosing plate 214 away from the accommodating cavity 201, and the plurality of fifth elastic members 350 are evenly spaced in the axial direction of the driving member 400.

[0070] In other embodiments, as needed, a plurality of third elastic members 330 may be protrudingly provided only on the side of the second enclosing plate 212 away from the accommodating cavity 201, a plurality of fourth elastic members 340 may be protrudingly provided on the side of the third enclosing plate 213 away from the accommodating cavity 201, or a plurality of fifth elastic members 350 may be protrudingly provided on the side of the fourth enclosing plate 214 away from the accommodating cavity 201.

[0071] Of course, in other embodiments, no corresponding elastic member 300 is provided on the side of the second enclosing plate 212 away from the accommodating cavity 201 , the side of the third enclosing plate 213 away from the accommodating cavity 201 , and the side of the fourth enclosing plate 214 away from the accommodating cavity 201 .

[0072] In some embodiments, the third elastic member 330, the fourth elastic member 340 and the fifth elastic member 350 are all bone structures made of silicone, and all extend in a direction perpendicular to the first enclosure plate 211. In addition, the third elastic member 330, the fourth elastic member 340 and the fifth elastic member 350 are all integrally formed with the assembly sleeve 200. That is, the third elastic member 330, the fourth elastic member 340, the fifth elastic member 350 and the assembly sleeve 200 can be formed by integral injection molding.

[0073] In other embodiments, the third elastic member 330, and / or the fourth elastic member 340, and / or the fifth elastic member 350 may be a bone structure made of rubber.

[0074] In other embodiments, the third elastic member 330, and / or the fourth elastic member 340, and / or the fifth elastic member 350 may also be a separate structure from the assembly sleeve 200, and may be fixedly connected to the assembly sleeve 200 by gluing or other methods.

[0075] In other embodiments, the third elastic member 330, and / or the fourth elastic member 340, and / or the fifth elastic member 350 may also be a columnar structure made of a flexible material such as silicone or rubber.

[0076] Of course, in other embodiments, the third elastic member 330, and / or the fourth elastic member 340, and / or the fifth elastic member 350 may also be elastic structures such as springs or spring sheets.

[0077] In the embodiment, corresponding elastic members 300 are arranged on the side of the second enclosure plate 212, the third enclosure plate 213 and the fourth enclosure plate 214 away from the accommodating cavity 201. On the one hand, the contact area between the corresponding enclosure plate 210 and the mounting base 100 can be reduced, and the resonance between the driving member 400 and the mounting base 100 can be reduced, so as to achieve the effect of damping and noise reduction. On the other hand, the elastic member 300 can also provide a buffering effect for the enclosure plate 210 at the corresponding position, that is, provide a buffering effect for the corresponding position of the driving member 400, so as to achieve the effect of damping and noise reduction.

[0078] like Figures 1 to 3 As shown, the vibration reduction and noise reduction structure 1000 further includes a fixing bracket 500, which is used to fix the assembly sleeve 200 to the mounting base 100. Specifically, in some embodiments, a connecting ear 231 is protrudingly provided on one side of the top plate 230 close to the third enclosure plate 213. The fixing bracket 500 is pressed on the side of the top plate 230 away from the accommodating cavity 201, and covers the connecting ear 231. The fixing bracket 500, the connecting ear 231 and the mounting base 100 are then locked and fixed by screws to firmly connect the assembly sleeve 200 to the mounting base 100, and the driving member 400 can also be fixedly installed on the mounting base 100.

[0079] In some other embodiments, the connecting ear 231 may also be protrudingly disposed on a side of the top plate 230 close to the fourth enclosing plate 214 or the opening structure 202 .

[0080] The embodiment also provides a surface cleaning device, including the shock-absorbing and noise-reducing structure 1000 provided in the embodiment. The surface cleaning device may be a sweeper, a floor scrubber, a desktop cleaning robot, a window cleaning robot, and the like. The mounting base 100 may be a structure such as a housing in the surface cleaning device or a support seat inside the housing. The driving member 400 may be a power structure such as a peristaltic pump or a motor in the surface cleaning device.
