Cleaning apparatus

Abstract

The application provides a cleaning device, which comprises a cover assembly, a first magnetic element and a second magnetic element. The cover assembly comprises a cover main body and a cover cap. The cover main body is provided with a first accommodating cavity and an opening communicating with the first accommodating cavity. The cover cap is arranged on the opening. The first accommodating cavity is used for accommodating at least part of a driving assembly and a damping element. The first magnetic element is arranged on the cover main body. The second magnetic element is arranged on the cover cap and is opposite to and spaced from the first magnetic element. The first magnetic element and the second magnetic element have the same polarity and are used for generating repulsion. When the driving assembly works and causes the air pressure inside the first accommodating cavity to increase, the repulsion can offset the pressure exerted by the air pressure on the damping element. By arranging the first magnetic element and the second magnetic element with the same polarity on the cover main body and the cover cap respectively, the repulsion generated by the first magnetic element and the second magnetic element can offset the pressure exerted by the air pressure on the damping element, so that the risk of fatigue damage of the damping element caused by the influence of the air pressure can be reduced.

Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and specifically to a cleaning device. Background Technology

[0002] In existing cleaning equipment, vibration damping components are typically installed inside the main body of the enclosure to suppress vibrations generated during the operation of the drive components and improve the smoothness and reliability of the equipment's operation. However, the drive components generate heat during operation, causing the internal temperature of the enclosure to rise. This increases the gas pressure inside the enclosure and acts on the vibration damping components, potentially leading to fatigue damage and other risks. Utility Model Content

[0005] The first magnetic component is located at one end of the cover body near the cover, and the second magnetic component is located on the side of the cover body facing the cover body.

[0006] The outer surface of the cover body is provided with a first mounting seat, and the first mounting seat is located at one end of the cover body close to the cover body. The side of the cover body facing the cover body is provided with a second mounting seat corresponding to the first mounting seat. A first magnetic element is provided at one end of the first mounting seat facing the cover body, and a second magnetic element is provided at one end of the second mounting seat facing the cover body.

[0007] The first mounting base includes multiple first sub-bases, which are spaced apart circumferentially along the main body of the cover. Each first sub-base is provided with a first magnetic element. The second mounting base includes multiple second sub-bases, which correspond one-to-one with the multiple first sub-bases. Each second sub-base is provided with a second magnetic element.

[0008] The first mounting base and the second mounting base are respectively arranged around the circumference of the main body and the cover. The cleaning device includes a plurality of first magnetic components and a plurality of second magnetic components. The plurality of first magnetic components are spaced apart on the first mounting base along the circumference of the main body, and the plurality of second magnetic components are spaced apart on the second mounting base along the circumference of the cover, and each corresponds to one of the plurality of first magnetic components.

[0009] The first mounting base and the second mounting base are provided with a groove and the other is provided with a protrusion, which is inserted into the groove; the first magnetic component and the second magnetic component are provided at the bottom of the groove and the other is provided on the end face of the protrusion near the bottom.

[0010] The bottom of the groove is provided with a first groove, and the raised end face is provided with a second groove; one of the first magnetic component and the second magnetic component is embedded in the first groove, and the other is embedded in the second groove.

[0011] The distance between the first magnetic component and the second magnetic component is 0.5mm-3mm.

[0012] The first magnetic component and the second magnetic component are permanent magnets or electromagnets.

[0013] The cover has a first connecting part on the side facing the main body of the cover. The first connecting part is inserted into the opening and has a receiving groove. The shock absorber includes the following interconnected parts: a main body part, which is sleeved on the outside of the drive assembly near the opening; and a second connecting part, a part of which is inserted into the receiving groove and the other part is inserted between the first connecting part and the inner edge of the opening.

[0014] The cleaning equipment also includes a housing, which has a second receiving cavity, and a cover assembly is disposed within the second receiving cavity.

[0015] The beneficial effects of the embodiments of this application, which differ from the prior art, are as follows: This application provides a cleaning device, which includes a cover assembly, a drive assembly, a shock absorber, a first magnetic element, and a second magnetic element. The cover assembly includes a cover body and a cover body. The cover body has a first accommodating cavity and an opening communicating with the first accommodating cavity. The cover body covers the opening. The first accommodating cavity is used to accommodate at least a portion of the drive assembly and the shock absorber. The first magnetic element is disposed on the cover body, and the second magnetic element is disposed on the cover body, and is opposite to and spaced apart from the first magnetic element. The first magnetic element and the second magnetic element have the same polarity and are used to generate a repulsive force so as to counteract the pressure exerted on the shock absorber by at least a portion of the air pressure when the drive assembly works and causes an increase in the air pressure inside the first accommodating cavity. By disposing a first magnetic element and a second magnetic element of the same polarity on the cover body and the cover body respectively, with the first magnetic element and the second magnetic element facing each other and spaced apart, the first magnetic element and the second magnetic element can generate a repulsive force. The repulsive force generated by the first magnetic element and the second magnetic element can act on the shock absorber through the cover body. The direction of the repulsive force acting on the shock absorber is opposite to or intersects with the direction of the air pressure inside the first accommodating cavity acting on the shock absorber. This allows the repulsive force to offset at least part of the pressure exerted by the air pressure on the shock absorber, thereby reducing the impact of the air pressure inside the first accommodating cavity on the shock absorber. This reduces the risk of fatigue damage to the shock absorber and helps to improve the shock absorption effect and service life of the shock absorber. Attached Figure Description

[0022] This application provides a cleaning device (not shown in the figure). For example... Figure 1 As shown, Figure 1 This is a cross-sectional view of a partial structure of an embodiment of the cleaning device provided in this application. The cleaning device includes a cover assembly 20, a drive assembly 40, a shock absorber 50, a first magnetic element 31, and a second magnetic element 32. The cover assembly 20 is used to accommodate the drive assembly 40 and the shock absorber 50, and is used to house the first magnetic element 31 and the second magnetic element 32. A first receiving cavity 21a is formed within the cover assembly 20, and the first receiving cavity 21a is configured as a nearly sealed cavity for accommodating the drive assembly 40 and the shock absorber 50. The cover assembly 20 can prevent dust, liquid, oil, or other foreign objects from contacting the drive assembly 40, reducing or avoiding phenomena such as motor insulation failure, short circuit, or mechanical jamming caused by this; and the cover assembly 20 can also block and absorb the propagation of sound waves generated by the drive assembly 40 during operation, so as to seal the noise within the first receiving cavity 21a, which helps to improve the quietness of the cleaning device. The shock absorber 50 can be disposed between the outer surface of the drive assembly 40 and the inner wall of the cover assembly 20. The shock absorber 50 can play a buffering role, which can block the vibration energy of the drive assembly 40 from being transmitted to the cover assembly 20 or to other components through the cover assembly 20, thereby improving the stability and reliability of the cleaning equipment operation.

[0023] like Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of the structure of an embodiment of the cover assembly of the cleaning equipment provided in this application; Figure 3 This is a schematic diagram of another embodiment of the cover assembly of the cleaning equipment provided in this application. The cover assembly 20 includes a cover body 21 and a cover 22. The cover body 21 has a first receiving cavity 21a and an opening 21b communicating with the first receiving cavity 21a. The cover 22 covers the opening 21b. The cover body 21 can be a cylindrical structure with an opening 21b at one end and a first receiving cavity 21a inside. The first receiving cavity 21a is used to accommodate at least a portion of the drive assembly 40 and the shock absorber 50. The cover body 21 and the cover 22 can be made of metal, engineering plastic, or composite material, but are not limited thereto. The cover body 21 and the cover 22 can be integrally formed by processes such as injection molding, stamping, or die casting, but are not limited thereto.

[0024] In some embodiments, the damping component 50 includes a damping pad, a spring damper, or an air cushion damper. The damping pad may be made of a polymer damping material such as rubber, silicone, polyurethane elastic elements, or polyurethane foam, but is not limited to these.

[0025] A first magnetic element 31 is disposed on the cover body 21, and a second magnetic element 32 is disposed on the cover body 22, and is disposed opposite to and spaced apart from the first magnetic element 31. The first magnetic element 31 and the second magnetic element 32 have the same polarity and are used to generate a repulsive force to counteract at least part of the pressure exerted by the air pressure on the shock absorber 50 when the drive assembly 40 operates and causes an increase in air pressure inside the first accommodating cavity 21a.

[0026] During operation, the drive assembly 40 generates heat from its internal windings, core, and other components. This heat dissipates into the first accommodating cavity 21a, heating the air inside. The gas inside the first accommodating cavity 21a expands due to the heat, increasing the pressure within it. This pressure acts on the damping component 50, causing it to experience upward or approximately upward pressure. If the damping component 50 is subjected to prolonged pressure within the first accommodating cavity 21a, it may suffer fatigue damage. For example, if the damping component 50 is a shock-absorbing pad, prolonged pressure within the first accommodating cavity 21a can force the internal polymer chains to straighten, slide, and rearrange to adapt to pressure changes. This causes the internal stress of the shock-absorbing pad to gradually decrease over time, potentially leading to hardening or cracking—essentially fatigue damage—and a decrease in its damping effect.

[0027] By disposing a first magnetic element 31 and a second magnetic element 32 of the same polarity on the cover body 21 and the cover body 22 respectively, with the first magnetic element 31 and the second magnetic element 32 facing each other and spaced apart, the first magnetic element 31 and the second magnetic element 32 can generate a repulsive force. The repulsive force generated by the first magnetic element 31 and the second magnetic element 32 can act on the shock absorber 50 through the cover body 21. The direction of the repulsive force acting on the shock absorber 50 is opposite to or intersects with the direction of the air pressure inside the first accommodating cavity 21a acting on the shock absorber 50. This allows the repulsive force to offset at least part of the pressure exerted by the air pressure on the shock absorber 50, thereby reducing the influence of the air pressure inside the first accommodating cavity 21a on the shock absorber 50. This reduces the risk of fatigue damage to the shock absorber 50 and helps to improve the shock absorption effect and service life of the shock absorber 50.

[0028] In addition, since the repulsive force can offset at least part of the pressure exerted by the air pressure on the shock absorber 50, the pressure exerted by the air pressure inside the first accommodating cavity 21a on the shock absorber 50 is weakened, thereby reducing the compressive force between the shock absorber 50 and the cover 22 and between the shock absorber 50 and the cover body 21. This reduces the risk of deformation or cracking of the cover 22 and the cover body 21 due to compression, and improves the overall reliability of the cleaning equipment.

[0029] In some embodiments, such as Figure 1 As shown, the first magnetic element 31 is located at one end of the cover body 21 near the cover body 22, and the second magnetic element 32 is located on the side of the cover body 22 facing the cover body 21.

[0030] The first magnetic element 31 can be disposed on the outer surface of the cover body 21, and the second magnetic element 32 can be disposed near the edge of the cover body 22, so that the second magnetic element 32 can be disposed opposite to and spaced apart from the first magnetic element 31, thereby generating a stable repulsive force.

[0031] In some embodiments, the outer surface of the cover body 21 is provided with a first mounting seat 60, and the first mounting seat 60 is located at one end of the cover body 21 near the cover body 22. The cover body 21 and the first mounting seat 60 can be an integrally formed structure; alternatively, the cover body 21 and the first mounting seat 60 can also be a separate structure, and the cover body 21 and the first mounting seat 60 can be fixed together by welding, bolting, snap-fitting, or adhesive bonding. The cover body 22 has a second mounting seat 70 corresponding to the first mounting seat 60 on the side facing the cover body 21. The second mounting seat 70 can be disposed near the edge of the cover body 22 to correspond to the first mounting seat 60. The cover body 22 and the second mounting seat 70 can be an integrally formed structure; alternatively, the cover body 22 and the second mounting seat 70 can also be a separate structure, and the cover body 22 and the second mounting seat 70 can be fixed together by welding, bolting, snap-fitting, or adhesive bonding.

[0032] The first mounting base 60 extends toward the cover 22, and the second mounting base 70 extends toward the cover body 21, that is, the first mounting base 60 and the second mounting base 70 extend in the direction they face each other. The first mounting base 60 and the second mounting base 70 are spaced apart from each other in the arrangement direction of the cover 22 and the cover body 21, such that the first magnetic element 31 provided on the first mounting base 60 and the second magnetic element 32 provided on the second mounting base 70 are spaced apart in the arrangement direction of the cover 22 and the cover body 21.

[0033] By setting a first mounting base 60 and a second mounting base 70, and respectively setting the first magnetic element 31 and the second magnetic element 32 on the first mounting base 60 and the second mounting base 70, on the one hand, the first mounting base 60 and the second mounting base 70 are respectively located in the outer area of ​​the cover body 21 and the cover 22, which can at least reduce the risk of collision or interference between the first magnetic element 31 and the second magnetic element 32 and other components during the assembly or disassembly of the cover body 21 and the cover 22, thereby protecting the first magnetic element 31 and the second magnetic element 32. On the other hand, the dimensions of the first mounting base 60 and the second mounting base 70 along the arrangement direction of the cover 22 and the cover body 21 can be designed as needed, so that the distance between the first magnetic element 31 and the second magnetic element 32 is within a suitable range, thereby controlling the magnitude of the repulsive force.

[0034] In some embodiments, such as Figure 2 and Figure 3 As shown, the first mounting base 60 includes a plurality of first sub-bases 61, which are spaced apart circumferentially along the main body 21. Each first sub-base 61 is provided with a first magnetic element 31. The second mounting base 70 includes a plurality of second sub-bases 71, which correspond one-to-one with the plurality of first sub-bases 61. Each second sub-base 71 is provided with a second magnetic element 32.

[0035] The number of first sub-bases 61 is equal to the number of second sub-bases 71, so that the plurality of first magnetic elements 31 provided on the first mounting base 60 and the plurality of second magnetic elements 32 provided on the second mounting base 70 can correspond one-to-one.

[0036] Multiple second sub-bases 71 are spaced apart circumferentially along the cover 22. When the cover 22 covers the opening 21b of the main body 21, the multiple second sub-bases 71 and multiple first sub-bases 61 are all spaced apart circumferentially around the opening 21b. Since each first sub-base 61 is provided with a first magnetic element 31 and each second sub-base 71 is provided with a second magnetic element 32, and the first magnetic element 31 and the second magnetic element 32 are also arranged circumferentially around the opening 21b, a uniform repulsive field is formed. This allows the repulsive force to act more evenly on the damping member 50, so as to evenly offset the pressure exerted on the damping member 50 by the air pressure inside the first accommodating cavity 21a. This can improve the uniformity of stress distribution inside the damping member 50, thereby not only further reducing the influence of the air pressure inside the first accommodating cavity 21a on the damping member 50, but also alleviating the stress concentration phenomenon in the damping member 50.

[0037] In the plurality of first sub-bases 61, the distance between two adjacent first sub-bases 61 is equal; in the plurality of second sub-bases 71, the distance between two adjacent second sub-bases 71 is equal, thereby forming a more uniform repulsive field. Of course, the distance between two adjacent first sub-bases 61 and the distance between two adjacent second sub-bases 71 may not be equal, and the specific arrangement can be selected according to actual needs.

[0038] In some embodiments, the first mounting base 60 and the second mounting base 70 are respectively arranged around the circumference of the cover body 21 and the cover 22. That is, the first mounting base 60 is arranged around the circumference of the cover body 21, and the second mounting base 70 is arranged around the circumference of the cover 22. When the cover 22 covers the opening 21b of the cover body 21, both the first mounting base 60 and the second mounting base 70 are arranged around the circumference of the opening 21b. The diameter of the first mounting base 60 can be equal to the diameter of the second mounting base 70, so that the first mounting base 60 and the second mounting base 70 can be arranged opposite each other in the arrangement direction of the cover body 21 and the cover 22.

[0039] The cleaning device includes a plurality of first magnetic elements 31 and a plurality of second magnetic elements 32. The plurality of first magnetic elements 31 are spaced apart on a first mounting base 60 along the circumference of the cover body 21. The plurality of second magnetic elements 32 are spaced apart on a second mounting base 70 along the circumference of the cover body 22. The plurality of second magnetic elements 32 correspond one-to-one with the plurality of first magnetic elements 31.

[0040] The number of first magnetic elements 31 is equal to the number of second magnetic elements 32, so that each of the multiple second magnetic elements 32 corresponds one-to-one with each of the multiple first magnetic elements 31. By setting multiple first magnetic elements 31 spaced apart on the first mounting base 60 arranged circumferentially around the cover body 21, and multiple second magnetic elements 32 spaced apart on the second mounting base 70 arranged circumferentially around the cover body 22, a uniform repulsive field can be formed, so that the repulsive force can act more evenly on the shock absorber 50, so as to evenly offset the pressure exerted on the shock absorber 50 by the air pressure inside the first accommodating cavity 21a, thereby improving the uniformity of stress distribution inside the shock absorber 50. This not only further reduces the influence of the air pressure inside the first accommodating cavity 21a on the shock absorber 50, but also alleviates the stress concentration phenomenon in the shock absorber 50.

[0041] In the plurality of first magnetic elements 31, the distance between two adjacent first magnetic elements 31 is equal; in the plurality of second magnetic elements 32, the distance between two adjacent second magnetic elements 32 is equal, thereby forming a more uniform repulsive field. Of course, the distance between two adjacent first magnetic elements 31 and the distance between two adjacent second magnetic elements 32 may not be equal, and the specific arrangement can be selected according to actual needs.

[0042] In some embodiments, such as Figures 1 to 3 As shown, one of the first mounting base 60 and the second mounting base 70 is provided with a groove 62, and the other of the first mounting base 60 and the second mounting base 70 is provided with a protrusion 72, which is inserted into the groove 62.

[0043] The depth direction of the groove 62 can be parallel to the arrangement direction of the cover body 21 and the cover 22, and the opening of the groove 62 faces the other of the first mounting base 60 and the second mounting base 70. The entire first mounting base 60 and the other of the second mounting base 70 can be a protrusion 72, or the protrusion 72 can be set on the side of the other of the first mounting base 60 and the second mounting base 70 facing the groove 62.

[0044] Wherein, if the first mounting base 60 and the second mounting base 70 respectively include a plurality of first sub-bases 61 and a plurality of second sub-bases 71, then each first sub-base 61 and each second sub-base 71 is provided with a groove 62 or a protrusion 72. If the first mounting base 60 and the second mounting base 70 are respectively arranged around the circumference of the cover body 21 and the cover 22, the groove 62 can be set as an annular groove and the protrusion 72 can be set as an annular protrusion, so that the groove 62 and the protrusion 72 are arranged around the circumference of the cover body 21 or the circumference of the cover 22; or, a plurality of grooves 62 can be provided on one of the first mounting base 60 and the second mounting base 70, and a plurality of protrusions 72 can be provided on the other, and the plurality of grooves 62 and the plurality of protrusions 72 correspond one-to-one.

[0045] One of the first magnetic element 31 and the second magnetic element 32 is disposed at the bottom of the groove 62, and the other is disposed on the end face of the protrusion 72 near the bottom of the groove 62. By inserting the protrusion 72 into the groove 62, on the one hand, the first magnetic element 31 and the second magnetic element 32 are prevented from being directly exposed to the outside of the first receiving cavity 21a, thereby protecting the first magnetic element 31 and the second magnetic element 32 from physical impact and avoiding the risk of breakage due to interference or collision with other components; on the other hand, the possibility of air, water or other foreign objects directly contacting the first magnetic element 31 and the second magnetic element 32 is reduced, thereby improving the reliability and stability of the first magnetic element 31 and the second magnetic element 32 in long-term use.

[0046] In some embodiments, such as Figure 1 As shown, a gap is provided between the outer surface of the protrusion 72 and the inner wall of the groove 62, which can reduce the interference between the protrusion 72 and the inner wall of the groove 62 during the process of the protrusion 72 being inserted into the groove 62, and reduce the risk of the first magnetic component 31 and the second magnetic component 32 becoming loose, falling off or breaking due to the interference between the protrusion 72 and the inner wall of the groove 62.

[0047] In some embodiments, the bottom of the groove 62 is provided with a first groove 63. The end face of the protrusion 72 is provided with a second groove 73. One of the first magnetic element 31 and the second magnetic element 32 is embedded in the first groove 63, and the other of the first magnetic element 31 and the second magnetic element 32 is embedded in the second groove 73.

[0048] Among them, the surface of one of the first magnetic element 31 and the second magnetic element 32 facing the protrusion 72 can be flush with the bottom of the groove 62, and the surface of the other of the first magnetic element 31 and the second magnetic element 32 facing the bottom of the groove 62 can be flush with the end face of the protrusion 72.

[0049] By embedding one of the first magnetic component 31 and the second magnetic component 32 in the first groove 63 and the other in the second groove 73, the positioning of the first magnetic component 31 and the second magnetic component 32 can be achieved. This reduces the risk of the first magnetic component 31 and the second magnetic component 32 becoming loose or falling off due to vibration during the operation of the drive assembly 40 or the cleaning equipment, and enables the first magnetic component 31 and the second magnetic component 32 to generate a stable and continuous repulsive force.

[0050] In some embodiments, the distance between the first magnetic element 31 and the second magnetic element 32 is 0.5mm-3mm. For example, the distance between the first magnetic element 31 and the second magnetic element 32 can be 0.5mm, 0.85mm, 0.93mm, 1mm, 1.25mm, 1.43mm, 1.5mm, 1.66mm, 1.85mm, 2mm, 2.22mm, 2.35mm, 2.5mm, 2.75mm, 2.88mm, 3mm, etc., but is not limited to these. Preferably, the distance between the first magnetic element 31 and the second magnetic element 32 is 1mm-2mm, for example, 1mm, 1.115mm, 1.285mm, 1.33mm, 1.4mm, 1.586mm, 1.6mm, 1.72mm, 1.77mm, 1.8mm, 1.835mm, 1.89mm, 1.9mm, 1.95mm, 1.988mm, 2mm, etc., but not limited to these.

[0051] By setting the distance between the first magnetic element 31 and the second magnetic element 32 within the range of 0.5mm-3mm, the intensity of the repulsive force generated by the first magnetic element 31 and the second magnetic element 32 is moderate. This ensures that the intensity of the repulsive force reaches a preset intensity that can offset at least part of the pressure exerted by the air pressure on the shock absorber 50, without causing any danger or damage to the shock absorber 50. For example, the intensity of the repulsive force is equal to, slightly less than, or slightly greater than the intensity of the pressure exerted by the air pressure on the shock absorber 50, thereby reducing the risk of fatigue damage to the shock absorber 50.

[0052] In some embodiments, the first magnetic element 31 and the second magnetic element 32 can be permanent magnets; or the first magnetic element 31 and the second magnetic element 32 can also be electromagnets. If the first magnetic element 31 and the second magnetic element 32 are electromagnets, the magnitude of the current flowing through the first magnetic element 31 and the second magnetic element 32 can be adjusted according to the output power of the drive assembly 40, the air pressure inside the first accommodating cavity 21a, or the temperature inside the first accommodating cavity 21a, thereby adjusting the magnitude of the repulsive force to improve the counteracting effect of the repulsive force on the pressure exerted by the air pressure on the shock absorber 50.

[0053] In some embodiments, such as Figure 1 As shown, the cover 22 has a first connecting portion 221 on the side facing the main body 21. The first connecting portion 221 is inserted into the opening 21b and has a receiving groove 221a. The shock absorber 50 includes a main body 51 and a second connecting portion 52 connected to each other. The main body 51 is sleeved on the outside of the end of the drive assembly 40 near the opening 21b. A portion of the second connecting portion 52 is inserted into the receiving groove 221a, and another portion is inserted between the first connecting portion 221 and the inner edge of the opening 21b.

[0054] The second mounting base 70 surrounds the outside of the first connecting portion 221 and is spaced apart from it. The first connecting portion 221 can be integrally formed on the side of the cover 22 facing the cover body 21, or the first connecting portion 221 can be provided on the side of the cover 22 facing the cover body 21 by welding, bolting, snap-fitting, or adhesive bonding. The main body 51 and the second connecting portion 52 of the shock absorber 50 can be integrally formed structures.

[0055] The diameter of the first connecting portion 221 can be smaller than the diameter of the opening 21b of the cover body 21, so that the first connecting portion 221 can be inserted into the opening 21b, and there is a gap between the outer surface of the first connecting portion 221 and the inner edge of the opening 21b. When the first connecting portion 221 is inserted into the opening 21b, the receiving groove 221a communicates with the first receiving cavity 21a, which facilitates the insertion of a portion of the second connecting portion 52 into the receiving groove 221a. A portion of the second connecting portion 52 can be fixed in the receiving groove 221a by means of interference fit, bolt connection, screw connection or snap connection.

[0056] The second connecting part 52 is spaced apart from another part so that the first connecting part 221 can be engaged between the second connecting part 52 and another part. The other part of the second connecting part 52 is inserted between the first connecting part 221 and the inner edge of the opening 21b to seal the opening 21b. This not only reduces the transmission of vibration or noise generated by the drive assembly 40 to the external environment through the opening 21b, thereby improving the vibration damping and noise reduction effect of the shock absorber 50, but also reduces or prevents liquids, dust, oil or other foreign objects from entering the first receiving cavity 21a, thereby reducing or preventing the occurrence of motor insulation failure, short circuit or mechanical jamming caused by this.

[0057] In some embodiments, the cleaning device further includes a housing 10. The housing 10 has a second receiving cavity 10a, and the cover assembly 20 is disposed within the second receiving cavity 10a.

[0058] The housing 10 serves as the basic carrier of the cleaning equipment, and it forms a second accommodating cavity 10a for accommodating components such as the cover assembly 20. The cover 22 of the cover assembly 20 can be detachably fixed to the housing 10 by means of bolts, adhesives, rivets, or snap-fit ​​connections. A sealing element 80 can be provided at the connection between the cover 22 and the housing 10 to seal the second accommodating cavity 10a, reducing or preventing liquids, dust, oil, or other foreign objects from entering the second accommodating cavity 10a. The sealing element 80 can be liquid sealant, foamed rubber, or sponge strips, but is not limited to these.

[0059] This application provides a cleaning device, which includes: a cover assembly 20, including a cover body 21 and a cover 22. The cover body 21 has a first accommodating cavity 21a and an opening 21b communicating with the first accommodating cavity 21a. The cover 22 covers the opening 21b. The first accommodating cavity 21a is used to accommodate at least a portion of the driving assembly 40 and the shock absorber 50. A first magnetic element 31 and a second magnetic element 32 are provided. The first magnetic element 31 is provided on the cover body 21, and the second magnetic element 32 is provided on the cover 22 and is opposite to and spaced apart from the first magnetic element 31. The first magnetic element 31 and the second magnetic element 32 have the same polarity and are used to generate a repulsive force to counteract the pressure exerted on the shock absorber 50 by at least a portion of the air pressure when the driving assembly 40 operates and causes an increase in the air pressure inside the first accommodating cavity 21a. By placing the first magnetic element 31 and the second magnetic element 32 with the same polarity on the cover body 21 and the cover body 22 respectively, the repulsive force generated by the first magnetic element 31 and the second magnetic element 32 can counteract the pressure exerted by the air pressure on the shock absorber 50, thereby reducing the risk of fatigue damage to the shock absorber 50 due to the influence of air pressure.

[0060] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
