Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a floor brush, a cleaning equipment and a cleaning system. Background Art

[0002] With the development of science and technology and the improvement of people's quality of life, cleaning equipment is increasingly used in people's lives.

[0003] The use of cleaning equipment has greatly reduced the burden on manpower. For example, a floor scrubber consists of a floor brush and a body connected to the brush. The body has a handle, and the user controls the movement of the body and the brush to clean the surface. However, the body is heavy, and holding the cleaning device for extended periods can cause arm fatigue, affecting the cleaning efficiency and user experience. Utility Model Content

[0004] The present application provides a floor brush, cleaning equipment and cleaning system that can effectively reduce or avoid user arm fatigue, thereby effectively improving cleaning efficiency and user experience.

[0005] One aspect of the present application provides a floor brush for use in a cleaning device, wherein an adapter is provided on the body of the cleaning device, and the floor brush comprises:

[0006] a housing, the adapter being rotatably connected to the housing, and the adapter being used to be connected to a body of the cleaning device;

[0007] a damping disc, the damping disc being connected to the adapter and rotating synchronously with the adapter;

[0008] A damping mechanism is located in the shell, and the damping mechanism abuts against the damping disk to provide resistance to the rotation of the damping disk, so as to prevent the adapter from rotating along a first direction, wherein the first direction is the rotation direction of the fuselage when switching from an upright state to a first working state.

[0009] During long-term use, the existing cleaning equipment will produce a compressive force on the arm, causing arm fatigue, affecting the cleaning efficiency of the cleaning equipment and the user experience. The embodiment of the present application sets a damping disc on the adapter of the floor brush, and sets a damping mechanism that cooperates with the damping disc in the floor brush. Through the abutment between the damping mechanism and the damping disc, the damping mechanism can generate an extrusion force on the damping disc, and the extrusion force can be converted into resistance to the rotation of the damping disc, so that the resistance applied by the damping mechanism to the damping disc can prevent the damping disc from rotating in a first direction. The resistance can be transmitted to the adapter and the body through the damping disc to prevent the body from rotating from the upright state to the first working state. In other words, when the body switches and rotates from the upright state to the first working state, the damping mechanism will apply an opposite force (i.e., resistance) to the body through the damping disc. This force will tend to move the body in a direction opposite to the first direction to lift the body. This force can offset the gravity of the machine to reduce the downward force of the machine, which effectively reduces the force exerted by the machine on the user's arm, allowing the user to lift the machine with less arm strength to control the movement of the machine and the floor brush. This can effectively reduce or avoid the user's arm fatigue, thereby effectively improving cleaning efficiency and user experience.

[0010] In one possible implementation, the damping mechanism abuts against the damping surface of the damping disc;

[0011] During the process of switching the fuselage from the upright state to the first working state along the first direction, the resistance provided by the damping mechanism to the damping disk increases; and / or, the fuselage also has a second working state, and during the process of switching the fuselage from the first working state to the second working state along the first direction, the resistance provided by the damping mechanism to the damping disk decreases.

[0012] As the angle of rotation of the device in the first direction increases, the degree of tilt of the device gradually increases, the angle between the device and the horizontal plane gradually decreases, and the weight exerted by the device on the arm gradually increases. At this time, the resistance exerted by the damping mechanism on the damping plate also gradually increases, which can balance the weight exerted by the device on the arm, allowing the user to rotate and control the device with less force.

[0013] Therefore, when the body switches from an upright state to a first working state along a first direction, by increasing the resistance of the damping mechanism to the damping disk, the resistance applied by the damping mechanism on the body and the force applied by the body on the arm can be kept in relative balance, so that the force applied by the body on the user's arm can always be kept small, which can effectively reduce or avoid the user's arm fatigue, thereby effectively improving cleaning efficiency and enhancing user experience.

[0014] The first operating state is when the body is tilted, during which the cleaning device can perform normal cleaning operations. The second operating state is when the body is lying flat, during which the cleaning device can clean low areas (e.g., under a bed). When the body is lying flat for cleaning low areas, the body is closer to the ground, requiring less support, and thus the force exerted on the arm.

[0015] In one possible implementation, the damping mechanism includes a fixed part and a movable part, the movable part includes an abutment assembly, and the abutment assembly abuts against the damping disk; when the fuselage switches from the upright state to the first working state along the first direction, the distance between the abutment point between the damping disk and the abutment assembly and the fixed part decreases.

[0016] As the distance between the abutment point between the damping disc and the abutment assembly and the fixed portion gradually decreases, the resistance exerted by the abutment assembly on the damping disc can be increased. Specifically, as the body switches from the upright position to the first operating position, the gravitational force exerted by the body on the arm gradually increases as the angle of rotation of the body in the first direction increases. Accordingly, as the resistance exerted by the damping mechanism on the body via the damping disc gradually increases, the resistance exerted by the damping mechanism on the body and the gravitational force exerted by the body on the arm can be balanced, effectively reducing the force on the arm and alleviating or preventing arm fatigue.

[0017] In one possible implementation, the abutment assembly is elastically retractable; during the rotation of the body relative to the floor brush, the abutment assembly is always in abutment with the damping disk and moves relative to the damping disk, and the damping mechanism applies resistance to the damping disk through the abutment assembly.

[0018] The elastically retractable abutment assembly allows it to maintain constant contact with the damping disc, thereby applying resistance to the damping disc. This effectively prevents problems such as resistance failure in the damping mechanism and effectively improves the reliability and stability of the damping mechanism's application of resistance to the damping disc. Furthermore, the abutment assembly maintains constant contact with the damping disc under the action of the elastic force and moves relative to the damping disc during rotation. During this movement, the abutment assembly can also apply friction to the damping disc to hinder rotation of the damping disc in the first direction, effectively increasing the resistance of the damping mechanism to the damping disc, thereby effectively improving the damping effect on the rotation of the fuselage.

[0019] In one possible implementation, the adapter includes a rotating shaft portion, and the adapter is rotatably connected to the housing via the rotating shaft portion; the damping disk rotates synchronously with the rotating shaft portion.

[0020] As the fuselage rotates about the rotating shaft, the damping disc also moves and rotates with the rotating shaft. The damping disc ensures that the abutment assembly remains in contact with the damping disc during its rotation, thereby applying resistance to the damping disc. This effectively prevents separation between the abutment assembly and the damping disc, preventing the abutment assembly and the damping disc from separating and thus interrupting the resistance of the damping mechanism. This effectively improves the reliability of the damping mechanism and the damping disc, and enhances the stability of the damping mechanism's resistance to the fuselage.

[0021] In a possible implementation, the damping disk includes a damping portion; when the fuselage is in the first working state, the abutting assembly abuts against the damping portion.

[0022] In one possible implementation, the damping plate further includes a limiting portion, and the limiting portion and the damping portion are arranged in sequence along the moving direction of the abutment assembly in the damping plate; when the fuselage is in the upright state, the abutment assembly abuts against the limiting portion, and the limiting portion is used to limit the movement of the abutment assembly toward the damping portion.

[0023] That is, when the fuselage switches from the upright state to the first working state, the cooperation relationship between the limit part and the abutment assembly can prevent the fuselage from switching from the upright state to the first working state, thereby reducing or avoiding the fuselage from randomly tilting toward the direction of the first working state in the upright state, and can effectively improve the reliability and stability of the fuselage in the upright state.

[0024] In a possible implementation, the limiting portion has a limiting groove that cooperates with the abutment assembly, and when the body is in an upright state, the abutment assembly is located in the limiting groove.

[0025] The limiting groove can limit the abutment assembly to prevent it from escaping from the limiting groove, thereby preventing the abutment assembly from moving from the limiting portion toward the damping portion. The cooperation between the abutment assembly and the limiting groove can thus limit the transition of the body from the upright position to the first working position, thereby increasing the resistance to rotation of the body in the first direction in the upright position, thereby confining the body in the upright position and effectively improving the reliability and stability of the body when set in the upright position.

[0026] In one possible implementation, the damping disc further includes a transition portion, which is located between the limiting portion and the damping portion; the transition portion has a transition groove, and a depth of the transition groove is less than a depth of the limiting groove.

[0027] The transition groove also serves to limit the position of the abutment assembly. Because the depth of the transition groove is shallower than that of the limiting groove, the limiting effect of the transition groove on the abutment assembly is weaker than that of the limiting groove. Specifically, when the fuselage rotates in the first direction in the upright position and switches to the first operating state, the damping mechanism initially exerts greater resistance on the fuselage, preventing it from leaving the upright position. This improves the reliability and stability of the fuselage in the upright position. As the angle of rotation of the fuselage in the first direction increases, the position of the fuselage changes, causing the relative position between the damping plate and the abutment assembly to change accordingly, thereby moving the abutment assembly into the transition groove on the damping plate. At this point, the transition groove is shallower, reducing the resistance to the fuselage, thereby reducing the resistance to rotation of the fuselage in the first direction. Maintaining the resistance of the damping mechanism on the fuselage within a reasonable range effectively improves the rationality of the resistance distribution of the damping mechanism to the fuselage.

[0028] In one possible implementation, along the movement direction of the abutment assembly on the damping disk, the damping portion includes a connected large damping area and a small damping area; the distance between the large damping area and the fixed portion is smaller than the distance between the small damping area and the fixed portion.

[0029] The gravity exerted on the arm varies depending on the rotational position of the fuselage, and therefore the required balancing resistance also varies accordingly. Depending on the position of the fuselage, the abutment assembly abuts against different damping areas on the damping disc. By making the distance between the large damping area and the fixed portion smaller than the distance between the small damping area and the fixed portion, the abutment assembly can apply different amounts of resistance to different parts of the damping disc, thereby allowing the damping mechanism to apply different amounts of resistance to the fuselage. This ensures that the resistance exerted by the damping mechanism on the fuselage is always balanced with the gravity exerted by the fuselage on the arm, thereby effectively improving the uniformity and rationality of the distribution of the resistance exerted by the damping mechanism on the fuselage.

[0030] In a possible implementation, the thickness of the large damping zone is greater than the thickness of the small damping zone, so that the resistance of the damping mechanism to the large damping zone is greater than the resistance of the damping mechanism to the small damping zone.

[0031] By varying the thickness of different parts of the damping disc, the distance between the corresponding parts of the damping disc and the fixed portion can be adjusted accordingly, thereby varying the resistance exerted by the damping mechanism on the damping disc. Therefore, by making the thickness of the large damping area greater than that of the small damping area, the resistance exerted by the damping mechanism on the large damping area can be made greater than that on the small damping area. This allows the abutment assembly to exert varying amounts of resistance on the damping disc, and consequently, the damping mechanism to exert varying amounts of resistance on the fuselage. This ensures that the resistance exerted by the damping mechanism on the fuselage is always balanced with the weight of the fuselage on the arm, effectively improving the uniformity and rationality of the distribution of the resistance exerted by the damping mechanism on the fuselage.

[0032] In one possible implementation, when the fuselage is in the first working state, the abutment assembly abuts against the large damping area; and when the fuselage is in the second working state, the abutment assembly abuts against the small damping area.

[0033] The cooperation between the abutment assembly and the damping plate can reduce the resistance of the abutment assembly to the damping plate, thereby balancing the load-bearing force of the body on the arm and the resistance of the damping mechanism on the body. Furthermore, this resistance can facilitate the rotation of the body to a flat position, preventing excessive resistance from the damping mechanism, which would make it difficult to lie flat, and thus helping to improve the reliability and stability of the body when lying flat.

[0034] In a possible implementation, the distance between the small damping zone and the fixing portion gradually increases from an end of the small damping zone close to the large damping zone to an end of the small damping zone far away from the large damping zone.

[0035] As the abutment assembly moves from the end of the small damping zone closer to the large damping zone toward the end farther from the large damping zone, as the distance between the small damping zone and the fixed portion gradually increases, the distance between the fixed portion and the damping disk can be gradually increased, causing the squeezing force of the abutment assembly on the damping disk to gradually decrease. Correspondingly, the resistance of the damping mechanism to the fuselage also gradually decreases. That is, in the process of the fuselage switching from the first working state to the second working state, as the fuselage gradually lies flat, the resistance of the damping mechanism to the fuselage gradually decreases. This can improve the smoothness of the change in the resistance of the damping mechanism to the fuselage, improve the balance between the resistance of the damping mechanism and the gravity of the fuselage, help improve the smoothness of the process of the fuselage lying flat, and improve the operability of the cleaning equipment.

[0036] In a possible implementation, the thickness of the small damping zone gradually decreases from an end close to the large damping zone to an end far from the large damping zone.

[0037] By gradually reducing the thickness of the small damping zone, the distance between the damping disc and the fixed portion can be gradually increased, thereby gradually reducing the compressive force of the abutment assembly on the damping disc. Correspondingly, the resistance of the damping mechanism to the cleaning machine body also gradually decreases. In other words, as the cleaning machine body switches from the first operating state to the second operating state, the resistance of the damping mechanism to the cleaning machine body gradually decreases as the cleaning machine body gradually lies flat. This improves the smoothness of the change in the resistance of the damping mechanism to the cleaning machine body, improves the balance between the resistance of the damping mechanism and the gravity of the cleaning machine body, and helps to improve the smoothness of the cleaning machine body lying flat, thereby enhancing the operability of the cleaning machine.

[0038] In one possible implementation, the large damping zone has a thickness of 5 mm to 10 mm. This thickness range allows the large damping zone to be relatively close to the fixed portion of the damping mechanism, thereby increasing the extrusion force of the damping disc on the damping mechanism and improving the pressing force of the damping mechanism on the damping disc. This allows the damping mechanism to provide a greater resistance to the damping disc, which can partially offset the weight of the fuselage in the corresponding state, thereby effectively reducing the weight of the fuselage on the hand.

[0039] In one possible implementation, the thickness of the small damping zone at the end away from the large damping zone is 2 mm to 4 mm. This thickness range allows the small damping zone to be relatively far from the fixed portion of the damping mechanism, thereby reducing the compression of the damping disc on the damping mechanism and lowering the pressing force of the damping mechanism on the damping disc. This allows the damping mechanism to provide less resistance to the damping disc, partially offsetting the weight of the fuselage in the corresponding state, thereby effectively reducing the weight of the fuselage on the hand.

[0040] In one possible implementation, the floor brush also includes a switch member; the damping disk also includes a contact, and when the body is in an upright state, the contact abuts against the switch member, and the switch member is used to stop the cleaning device when the contact abuts against the switch member.

[0041] When the body is in an upright state, the cleaning device does not perform cleaning work. At this time, the cleaning device is in a shutdown state through the cooperation between the contacts and the switch parts, which can reduce or avoid the cleaning device being started due to accidental touch during the parking process, and can prevent the cleaning device from being damaged due to accidental touch when parked, which helps to improve the shutdown protection of the cleaning equipment.

[0042] In one possible implementation, the switch component includes a main body and a spring portion; when the body is in an upright state, the contact abuts against the spring portion, the spring is in electrical contact with the main body and sends the signal to the controller to stop the cleaning device.

[0043] When the main body rotates in a first direction from the upright position to the first operating state, the damping disc rotates with it. At this point, the contacts on the damping disc rotate with the damping disc and separate from the spring element, preventing the contacts from squeezing the spring element. The spring element, under its own resilience, can restore its disconnection from the main body. Upon receiving the disconnection signal, the controller activates the cleaning device to allow it to continue cleaning. This effectively improves the sensitivity of the switch element, reduces or prevents misjudgments, and contributes to improved reliability and stability.

[0044] In one possible implementation, the damping mechanism also includes an elastic member, and the fixed portion includes a mounting base; the mounting base is connected to the shell, the abutment assembly is slidably connected to the mounting base, one end of the elastic member is connected to the mounting base, and the other end is connected to the abutment assembly, and the elastic member is in an elastically compressed state.

[0045] The mounting base can provide mounting fixation for the damping mechanism, so that the damping mechanism can be installed on the shell through the mounting base, which can reduce or avoid the displacement or shaking of the damping mechanism in the shell, and help improve the reliability and stability of the damping mechanism in the shell.

[0046] The elastic member can push the abutment assembly out of the mounting base, so that the abutment assembly can always be in abutment contact with the damping disk, thereby enabling the abutment assembly to always apply resistance to the damping disk, which can effectively reduce or avoid failure of the damping mechanism, thereby effectively improving the reliability and stability of the damping mechanism's effect on the fuselage.

[0047] In one possible implementation, the abutment assembly includes a top ball and a top ball fixing member; the top ball fixing member is slidably connected to the mounting base, the top ball is connected to the top ball fixing member, and the other end of the elastic member is connected to the top ball fixing member.

[0048] During operation of the damping mechanism, the elastic member pushes the top ball fixture to expand and contract, causing the top ball fixture to drive the top ball to expand and contract, thereby allowing the damping mechanism to apply resistance to the damping disc through the top ball. The relatively rounded and smooth surface of the top ball prevents any jamming between the abutment assembly and the damping disc, helping to improve the smoothness of the fit between the abutment assembly and the damping disc, and enhancing the stability of the relative movement between the abutment assembly and the damping disc.

[0049] Moreover, the spherical top ball can also reduce or avoid scratches and wear on the damping disc caused by the top ball, which helps to improve the protection of the damping disc and extend the service life of the damping disc.

[0050] The top ball fixing member includes a ball holder portion and a retaining portion arranged around the ball holder portion; in one possible implementation, the ball holder portion and the retaining portion are jointly arranged to form a receiving cavity, and the top ball is located in the receiving cavity.

[0051] The ball holder provides propulsion for the top ball, and the elastic force of the elastic member is transmitted to the top ball through the ball holder, allowing the top ball to expand and contract. The retaining portion limits the top ball, preventing it from moving or shifting, helping to improve the reliability and stability of the connection between the top ball and the top ball fixing component, and enhancing the overall structural stability of the abutment assembly.

[0052] In a possible implementation, the enclosure portion further has a limiting protrusion, which is arranged around the inner circle of the enclosure portion and located at an end of the enclosure portion away from the ball holder portion.

[0053] The limiting protrusion can limit the top ball in the axial direction of the enclosure part, which can reduce or prevent the top ball from falling out along the axial direction of the enclosure part, help to improve the reliability and stability of the connection between the top ball and the top ball fixing part, and enhance the overall structural stability of the abutment assembly.

[0054] In one possible implementation, the mounting base includes a fixed base and a spring fixed base;

[0055] The fixed base is connected to the shell, the spring fixing seat is located on a side of the fixed base facing away from the damping disc and is connected to the fixed base; the elastic member is connected to the spring fixing seat.

[0056] By decomposing the mounting base into a fixed base and a spring retainer, a more complex mounting base can be divided into a fixed base and a spring retainer with simpler structures. This facilitates the production of the mounting base and reduces the overall production difficulty and cost of the mounting base. Furthermore, it facilitates the installation of the elastic member on the mounting base, reduces the difficulty of assembling the elastic member and the mounting base, and thus improves the efficiency of the assembly between the elastic member and the mounting base.

[0057] In a possible implementation, there are two damping discs and two damping mechanisms, and the two damping discs and two damping mechanisms are respectively located on two sides of the adapter.

[0058] In this way, the damping mechanism can provide resistance to the fuselage on both sides of the adapter, which helps to improve the balance and equilibrium of the overall force on the fuselage, and can reduce or avoid the tilting of the fuselage due to uneven force, thereby improving the reliability and stability of the fuselage rotation.

[0059] A second aspect of the present application provides a cleaning device comprising a body and any of the above-described floor brushes, wherein the body is connected to the adapter of the floor brush. By including the above-described floor brush in the cleaning device, arm fatigue caused by prolonged use can be effectively reduced, thereby effectively improving the user experience of the cleaning device and enhancing the cleaning effect of the cleaning device.

[0060] A third aspect of the present application provides a cleaning system, comprising a base station and the above-mentioned cleaning device. By including the above-mentioned cleaning device in the cleaning system, the user experience of the cleaning system can be effectively improved and the cleaning effect of the cleaning system can be enhanced.

[0061] The floor brush, cleaning device, and cleaning system provided in the embodiments of the present application, by providing a damping disk on the adapter of the floor brush and providing a damping mechanism that cooperates with the damping disk in the floor brush, the resistance exerted by the damping mechanism on the damping disk can prevent the body from rotating from the upright state toward the first working state. That is, when the body switches and rotates from the upright state to the first working state, the damping mechanism will exert opposite resistance on the body through the damping disk, and this resistance will tend to move the body in a direction opposite to the first direction to lift the body. This resistance can offset the gravity of the body itself to reduce the resultant downward force of the body, which can effectively reduce the force exerted by the body on the user's arm, so that the user only needs to use less arm strength to lift the body to control the movement of the body and the floor brush. It can effectively reduce or avoid the user's arm fatigue, thereby effectively improving cleaning efficiency and user experience. By providing a retaining groove on the damping disc and positioning the abutment assembly in the damping mechanism within the retaining groove when the body is in the upright position, the retaining groove can restrain the abutment assembly, preventing it from dislodging from the retaining groove. This can limit the transition of the body from the upright position to the first operating position, allowing the body to be restrained in the upright position, thereby effectively improving the reliability and stability of the body in the upright position. Furthermore, by providing the damping disc with a large damping area and a small damping area, the damping mechanism can apply varying amounts of resistance to the body. This ensures that the resistance applied by the damping mechanism consistently partially offsets the weight of the body on the arm, effectively improving the uniformity and rationality of the resistance distribution of the damping mechanism. By ensuring that the abutment assembly abuts the large damping area when the body is in the first operating position and the small damping area when the body is in the second operating position, the damping mechanism can apply greater resistance to the body during routine cleaning, effectively reducing or preventing arm fatigue. When the cleaning device is lying flat for cleaning, the reduced resistance applied to it effectively prevents the damping mechanism from exerting excessive resistance on the cleaning device, which could prevent the cleaning device from lying flat. This helps improve the reliability and stability of the cleaning device when lying flat. Furthermore, by providing a contact on the damping disc and abutting the switch when the cleaning device is in an upright position, the switch shuts down the cleaning device. This reduces or prevents accidental activation of the cleaning device while it is parked, preventing damage to the cleaning device caused by accidental activation while parked, and improving shutdown protection for the cleaning device.

[0087] As mentioned in the above background technology, existing cleaning equipment may cause fatigue in the user's arms during long-term use, affecting the cleaning efficiency of the cleaning equipment and user experience.

[0088] To address the above-mentioned issues, the present application provides a floor brush, cleaning device, and cleaning system. A damping disc is provided on the floor brush adapter, and a damping mechanism is provided in the floor brush that cooperates with the damping disc. The resistance exerted by the damping mechanism on the damping disc can prevent the damping disc from rotating in a first direction. This resistance can be transmitted to the adapter and the body through the damping disc to prevent the body from rotating from the upright position to the first working position. In other words, when the body switches from the upright position to the first working position, the damping mechanism exerts an opposite force (i.e., resistance) on the body through the damping disc. This force tends to move the body in a direction opposite to the first direction, thereby lifting the body. This force can offset the body's own gravity to reduce the combined downward force on the body. This can effectively reduce the force exerted by the body on the user's arm, allowing the user to lift the body with less arm strength to control the movement of the body and the floor brush. This can effectively reduce or avoid arm fatigue, thereby effectively improving cleaning efficiency and user experience.

[0089] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0090] An embodiment of the present application provides a cleaning device, which can be a household handheld floor scrubber. The cleaning device is mainly used to clean stains and dust on the surface to be cleaned. The surface to be cleaned can be a floor, wall, or surface of an object to be cleaned with different degrees of roughness. The embodiment of the present application does not specifically limit the type of surface to be cleaned.

[0091] Figure 1 A schematic structural diagram of a floor brush assembly provided in an embodiment of the present application.

[0092] See also Figure 1 As shown, the cleaning device may include a floor brush 100. When in operation, the cleaning device moves on the surface to be cleaned, and the surface to be cleaned is cleaned by the floor brush 100 contacting and rubbing with the surface to be cleaned.

[0093] See also Figure 1 As shown, the floor brush 100 may include a housing 110, a roller brush 160, and running wheels 170. The housing 110 is the main supporting structure of the floor brush 100, and the roller brush 160 and the running wheels 170 may both be mounted on the housing 110. For example, the housing 110 may have a receiving cavity, and the roller brush 160 may be located in the receiving cavity of the housing 110, and the roller brush 160 may rotate around its own axis.

[0094] When the cleaning device is cleaning, the roller brush 160 contacts the surface to be cleaned. The motor installed in the roller brush 160 drives the roller brush 160 to rotate at high speed, so that the roller brush 160 can frictionally contact the surface to be cleaned to clean the surface. The running wheel 170 contacts the surface to be cleaned and rolls along the surface to assist the cleaning device in moving on the surface to be cleaned, thereby improving the stability of the floor brush 100 moving on the surface to be cleaned.

[0095] Among them, the clean water tank can provide cleaning liquid to the roller brush 160 to soak the roller brush 160, so that the roller brush 160 can soak the stains on the surface to be cleaned during the cleaning process, reduce the adhesion of the stains, and thus facilitate cleaning the stains from the surface to be cleaned.

[0096] Along the travel direction of the floor brush 100, the roller brush 160 can be mounted at the front end of the housing 110, and the running wheels 170 can be mounted at the rear end of the housing 110. This facilitates control of the travel direction of the floor brush 100 and helps maintain the balance of the floor brush 100 during travel. Furthermore, the roller brush 160 preferentially contacts the surface to be cleaned, and the front of the roller brush 160 is unobstructed, which facilitates the roller brush 160's cleaning of the surface to be cleaned.

[0097] The cleaning device may further include a body (not shown), and the floor brush 100 may be rotatably connected to the bottom of the body. During cleaning, the user may hold the body and swing the body to rotate the floor brush 100 relative to the body, allowing the floor brush 100 to move to different areas (e.g., under a table, under a cabinet, etc.) so that the floor brush 100 can clean different areas.

[0098] The machine body may be equipped with components such as a clean water tank (not shown) and a dirty water tank (not shown). The clean water tank is used to hold cleaning liquid. When the cleaning device is in operation, the cleaning liquid in the clean water tank is sprayed onto the floor brush 100 or the surface to be cleaned in front of the floor brush 100, thereby cooperating with the floor brush 100 to clean the surface to be cleaned. The dirty water on the surface to be cleaned (along with foreign matter such as particles and hair) is sucked into the dirty water tank, completing the cleaning process.

[0099] Figure 2 This is a schematic structural diagram of the damping mechanism and damping disc provided in the floor brush according to an embodiment of the present application.

[0100] See also Figure 2 As shown, an adapter 120 is provided on the body of the cleaning device, and the adapter 120 can be rotatably connected to the shell 110. The adapter 120 can be used to connect to the body of the cleaning device so that the floor brush 100 can be rotatably connected to the body through the adapter 120.

[0101] The floor brush 100 may also include a damping disc 130 and a damping mechanism 140. The damping disc 130 may be connected to the adapter 120, and the damping disc 130 may rotate synchronously with the adapter 120. That is, when the body rotates relative to the floor brush 100 through the adapter 120, the damping disc 130 on the adapter 120 also rotates relative to the housing 110 of the floor brush 100 together with the body.

[0102] The damping mechanism 140 may be located in the housing 110. The damping mechanism 140 may abut against the damping surface of the damping disc 130, generating contact friction to hinder the damping mechanism 140 from moving relative to the damping disc 130, thereby providing resistance to the rotation of the damping disc 130. The resistance may hinder the adapter 120 from rotating in the first direction (i.e., Figure 2 The first direction x is the rotation direction of the fuselage when it switches from the upright state to the first working state.

[0103] When the cleaning device is stopped and not working, the fuselage can be in an upright state, at which time, the angle between the fuselage and the horizontal plane can be close to or slightly greater than 90°. When the cleaning device is in working state, the fuselage can be in an inclined state or a flat state.

[0104] Specifically, when the cleaning device performs routine surface cleaning, the body can be in an inclined state, and in this case, the angle between the body and the horizontal plane can be less than 90 degrees. The state of the body when the cleaning device performs routine cleaning can be defined as the first working state, that is, when the body is in the first working state, the body is in an inclined state.

[0105] When the cleaning device is cleaning a low area (e.g., under a bed, under a cabinet, etc.), the body can be in a lying state. At this time, the body is parallel or nearly parallel to the horizontal plane, or the angle between the body and the horizontal plane is very small, so that the floor brush 100 can enter the low area for cleaning. When the cleaning device is cleaning a low area, the body can be defined as the second working state, that is, when the body is in the second working state, the body is in a lying state.

[0106] The resistance applied by the damping mechanism 140 to the damping disc 130 can prevent the damping disc 130 from rotating along the first direction x. The resistance can be transmitted to the adapter 120 and the body through the damping disc 130 to prevent the body from rotating from the upright state to the first working state. In other words, when the body switches and rotates from the upright state to the first working state, the damping mechanism 140 will apply an opposite force (i.e., resistance) to the body through the damping disc 130. This force will tend to move the body in the direction opposite to the first direction x to lift the body. This force can offset the gravity of the body itself to reduce the downward force of the body, which can effectively reduce the force applied by the body to the user's arm, so that the user only needs to use less arm strength to lift the body to control the movement of the body and the floor brush 100. It can effectively reduce or avoid the user's arm fatigue, thereby effectively improving cleaning efficiency and user experience.

[0107] Continue to see Figure 2 As shown, the damping mechanism 140 can abut against the side of the damping plate 130. When the device switches from the upright position to the first operating position along the first direction x, the resistance exerted by the damping mechanism 140 on the damping plate 130 increases. For example, when the device initially switches from the upright position to the first operating position, the degree of tilt of the device is relatively small, that is, the angle between the device and the horizontal plane is relatively large, and the gravitational force exerted by the device on the arm is also relatively small. At this time, the resistance exerted by the damping mechanism 140 on the damping plate 130 is also relatively small, which can partially offset the gravitational force exerted by the device on the arm, allowing the user to rotate and control the device with less force.

[0108] As the angle of rotation of the device along the first direction x increases, the degree of tilt of the device gradually increases, the angle between the device and the horizontal plane gradually decreases, and the gravity exerted by the device on the arm gradually increases. At this time, the resistance exerted by the damping mechanism 140 on the damping plate 130 also gradually increases, partially offsetting the gravity exerted by the device on the arm, allowing the user to rotate and control the device with less force.

[0109] Therefore, when the body switches from an upright state to a first working state along the first direction x, by increasing the resistance of the damping mechanism 140 to the damping disk 130, the resistance applied by the damping mechanism 140 on the body and the force applied by the body on the arm can be kept in relative balance, so that the force applied by the body on the user's arm can always be kept small, which can effectively reduce or avoid the user's arm fatigue, thereby effectively improving the cleaning efficiency and enhancing the user experience.

[0110] Figure 3 This is a schematic diagram of the structure of the first damping mechanism and the damping disk provided in the embodiment of the present application. Figure 4 A schematic structural diagram of the cooperation between the second damping mechanism and the damping disk provided in an embodiment of the present application.

[0111] Among them, see Figure 3 and Figure 4 As shown, the damping mechanism 140 may include a fixing portion (e.g., Figure 3 The mounting base 141 in the embodiment and the movable portion (e.g., Figure 3 The abutment assembly 143 in the embodiment of the present invention may be fixedly connected to the housing 110, and the movable portion may be movably connected to the fixed portion. For example, the fixed portion and the housing 110 may be connected by a snap connection, a buckle connection, a bolt connection, etc., so that the fixed portion and the housing 110 do not move relative to each other.

[0112] Relative motion can occur between the movable part and the fixed part, wherein Figure 3 As shown, the movable portion may include an abutting assembly 143, which may abut against the damping disc 130. When the body switches from the upright state to the first working state along the first direction x, the distance between the abutment point between the damping disc 130 and the abutting assembly 143 and the fixed portion decreases.

[0113] As the distance between the abutment point between damping disc 130 and abutment assembly 143 and the fixed portion gradually decreases, the resistance exerted by abutment assembly 143 on damping disc 130 can be increased. Specifically, as the body switches from the upright position to the first operating position, the gravity exerted by the body on the arm gradually increases as the angle of rotation of the body in the first direction x increases. Accordingly, as the resistance exerted by damping mechanism 140 on the body via damping disc 130 also gradually increases, the resistance exerted by damping mechanism 140 on the body and the gravity exerted by the body on the arm can be partially offset, effectively reducing the force on the arm and alleviating or preventing arm fatigue.

[0114] The abutment assembly 143 may be an elastically retractable structure. For example, the abutment assembly 143 may be connected to the fixed portion via an elastic member 142, etc., so that the abutment assembly 143 can elastically retract relative to the fixed portion. During the rotation of the brush body relative to the floor brush 100, the abutment assembly 143 can always abut against the damping plate 130 and move relative to the damping plate 130.

[0115] The damping mechanism 140 can apply resistance to the damping disc 130 via the abutment assembly 143. The elastically retractable abutment assembly 143 can maintain constant contact with the damping disc 130 to apply resistance to the damping disc 130. This effectively prevents problems such as resistance failure in the damping mechanism 140 and effectively improves the reliability and stability of the damping mechanism 140's application of resistance to the damping disc 130. Furthermore, the abutment assembly 143, under the action of the elastic force, always maintains contact with the damping disc 130 and moves relative to the damping disc 130 during rotation of the damping disc 130. During this movement, the abutment assembly 143 can also apply friction to the damping disc 130 to hinder rotation of the damping disc 130 in the first direction x. This effectively increases the resistance of the damping mechanism 140 to the damping disc 130, thereby effectively improving the damping effect on the rotation of the fuselage.

[0116] See also Figure 3 As shown, in some examples, two damping mechanisms 140 may be coupled to a damping disc 130. The two damping mechanisms 140 may be located on either side of the damping disc 130, respectively. This allows the two damping mechanisms 140 to simultaneously apply resistance to the damping disc 130 from both sides thereof, thereby hindering the damping disc 130 from rotating in the first direction x. This improves the uniformity of the resistance applied by the damping mechanisms 140 to the damping disc 130, reduces or prevents the damping disc 130 from tilting due to the damping mechanism 140 applying resistance from one side, thereby affecting the normal rotation of the fuselage, and helps improve the reliability and stability of the fuselage rotation.

[0117] Continue to see Figure 3 and Figure 4As shown, the floor brush 100 may further include a switch member 150, and the damping disc 130 may further include a contact 134. When the cleaning device is in an upright position, the contact 134 may abut against the switch member 150. The switch member 150 may be used to shut down the cleaning device when the contact 134 abuts against the switch member 150. For example, the contact 134 may protrude from the outer surface of the peripheral side of the damping disc 130. When the cleaning device is in an upright position, the contact 134 is at a higher height and may abut against the switch member 150, thereby triggering the switch member 150. The switch member 150 may then send a control signal to a controller in the cleaning device, causing the controller to shut down the cleaning device. For example, when the cleaning device is in a shut-down state, both the main fan in the cleaning device and the drive motor in the roller brush are in a stopped state.

[0118] When the body is in an upright state, the cleaning device does not perform cleaning work. At this time, the cleaning device is in a shutdown state through the cooperation between the contact 134 and the switch 150, which can reduce or avoid the cleaning device being started due to accidental contact during the parking process, and can prevent the cleaning device from being damaged due to accidental contact when parked, which helps to improve the shutdown protection of the cleaning device.

[0119] For example, as shown in the figure, the switch component 150 may include a main body 151 and a spring portion 152. When the body is in an upright state, the contact 134 may abut against the spring portion 152, and the spring portion 152 may be elastically deformed. The spring portion 152 may be electrically contacted with the main body 151 under the squeezing action of the contact 134. At this time, after the spring portion 152 is electrically contacted with the main body 151, the switch component 150 may send a control signal to the controller in the cleaning device to enable the controller to shut down the cleaning device.

[0120] When the main body rotates from the upright position in the first direction x and switches to the first operating state, the damping disc 130 also rotates with the main body. At this point, the contact 134 on the damping disc 130 rotates with the damping disc 130 and separates from the spring portion 152, so that the contact 134 does not squeeze the spring portion 152. Under the action of its own rebound force, the spring portion 152 can restore its disconnection from the main body 151. Upon receiving the disconnection signal from the switch 150, the controller can power on the cleaning device to allow the cleaning device to perform subsequent cleaning operations. This effectively improves the sensitivity of the switch 150, reduces or prevents misjudgments by the switch 150, and helps improve the reliability and stability of the switch 150.

[0121] Figure 5 This is an exploded view of a floor brush 100 provided in an embodiment of the present application. Figure 6 This is an exploded view of the second damping mechanism 140 and the damping disc 130 provided in an embodiment of the present application.

[0122] See also Figure 5 and Figure 6 As shown, the adapter 120 may include a rotating shaft portion 122, and the adapter 120 can be rotatably connected to the housing 110 via the rotating shaft portion 122. For example, the housing 110 may have a rotating hole (not shown in the figure), and the rotating shaft portion 122 can extend into the rotating hole and rotatably cooperate with the rotating hole. In this way, the body can be rotatably connected to the floor brush 100 through the cooperation of the rotating shaft portion 122 and the rotating hole. During the rotation process, the body can rotate around the rotating hole to rotate relative to the housing 110, and thus rotate relative to the floor brush 100, to switch between the upright state and the first working state.

[0123] The damping disc 130 can rotate synchronously with the rotating shaft portion 122. For example, the damping disc 130 can have a sector-shaped structure and can be disposed around at least a portion of the outer circumference of the rotating shaft portion 122. The abutment assembly 143 can abut against the sector-shaped surface of the damping disc 130, where the sector-shaped surface refers to the surface of the damping disc 130 that is perpendicular to the axis of the rotating shaft portion 122. As the damping disc 130 rotates, the abutment assembly 143 can abut against the damping disc 130 and move around the axis of the rotating shaft portion 122.

[0124] As the fuselage rotates via the rotating shaft 122, the damping plate 130 can also move and rotate along with the rotating shaft 122. The fan-shaped structure of the damping plate 130 ensures that the abutment assembly 143 is always in contact with the damping plate 130 during its rotation, thereby applying resistance to the damping plate 130. This effectively prevents the abutment assembly 143 from separating from the damping plate 130, preventing the abutment assembly 143 from separating from the damping plate 130 and thus preventing the damping mechanism 140 from experiencing a disruption in its resistance. This effectively improves the reliability of the coordination between the damping mechanism 140 and the damping plate 130, and enhances the stability of the resistance provided by the damping mechanism 140 to the fuselage.

[0125] Figure 7 A schematic structural diagram of a damping disc 130 provided in an embodiment of the present application.

[0126] Continue to see Figure 7 As shown, along the movement direction of the abutment assembly 143 in the damping plate 130, the damping plate 130 may include a connected limit portion 131 and a damping portion 132. When the fuselage is in the upright position, the abutment assembly 143 may abut against the limit portion 131. When the fuselage is in the first operating position, the abutment assembly 143 may abut against the damping portion 132, and the limit portion 131 may be used to limit the movement of the abutment assembly 143 toward the damping portion 132.

[0127] That is, when the fuselage switches from the upright state to the first working state, the cooperation relationship between the limit portion 131 and the abutment assembly 143 can prevent the fuselage from switching from the upright state to the first working state, thereby reducing or avoiding the fuselage from randomly tilting toward the direction of the first working state when in the upright state, and can effectively improve the reliability and stability of the fuselage in the upright state.

[0128] Continue to see Figure 7 As shown, the limiting portion 131 may have a limiting groove 1311 that cooperates with the abutting assembly 143. When the body is in the upright state, the abutting assembly 143 may be located in the limiting groove 1311. The limiting groove 1311 can limit the abutting assembly 143 to prevent the abutting assembly 143 from escaping from the limiting groove 1311, thereby preventing the abutting assembly 143 from moving from the limiting portion 131 toward the damping portion 132.

[0129] In this way, through the cooperation between the abutment component 143 and the limiting groove 1311, the fuselage can be limited from switching from the upright state to the first working state, and the resistance of the fuselage to rotate toward the first direction x in the upright state can be increased, so that the fuselage can be limited to the upright state, thereby effectively improving the reliability and stability of the fuselage in the upright state.

[0130] Continue to see Figure 7 As shown, the damping disc 130 may further include a transition portion 133, which may be located between the limiting portion 131 and the damping portion 132. The transition portion 133 may have a transition groove 1331, and the depth of the transition groove 1331 may be less than the depth of the limiting groove 1311. The transition groove 1331 may also limit the abutment assembly 143. Since the depth of the transition groove 1331 is shallower than the depth of the limiting groove 1311, the limiting effect of the transition groove 1331 on the abutment assembly 143 is also weaker than the limiting effect of the limiting groove 1311 on the abutment assembly 143.

[0131] Specifically, when the fuselage rotates in the first direction x in the upright position and switches to the first operating state, the damping mechanism 140 initially exerts a greater resistance on the fuselage, preventing it from leaving the upright position. This improves the reliability and stability of the fuselage in the upright position. As the rotation angle of the fuselage in the first direction x increases, the position of the fuselage changes. This causes the relative position between the damping plate 130 and the abutment assembly 143 to change accordingly, causing the abutment assembly 143 to move into the transition groove 1331 on the damping plate 130. At this point, the depth of the transition groove 1331 is relatively shallow, and the resistance to the fuselage is correspondingly reduced, thereby reducing the resistance to rotation of the fuselage in the first direction x. Maintaining the resistance of the damping mechanism 140 on the fuselage within a reasonable range effectively improves the rationality of the damping mechanism 140's resistance distribution over the entire fuselage.

[0132] Continue to see Figure 7 As shown, along the moving direction of the abutment assembly 143 on the damping disk 130, the damping portion 132 may include a large damping area 1321 and a small damping area 1322, wherein the distance between the large damping area 1321 and the fixing portion may be smaller than the distance between the small damping area 1322 and the fixing portion.

[0133] When the abutment assembly 143 abuts the large damping area 1321, the distance between the large damping area 1321 and the fixed portion of the damping mechanism is small, which in turn reduces the distance between the abutment point of the damping disc 130 and the abutment assembly 143 and the fixed portion. The elastic compression of the abutment assembly 143 by the damping disc 130 is also large, resulting in a greater resistance from the abutment assembly 143 to the large damping area 1321.

[0134] Conversely, when the abutment assembly 143 abuts the small damping area 1322, the distance between the small damping area 1322 and the fixed portion is larger, which in turn increases the distance between the fixed portion and the abutment point where the damping disc 130 abuts the abutment assembly 143. The amount of elastic compression of the abutment assembly 143 by the damping disc 130 is also smaller, resulting in a smaller resistance exerted by the abutment assembly 143 on the large damping area 1321.

[0135] The gravity exerted on the arm varies depending on the rotational position of the fuselage, and therefore the required balancing resistance also varies accordingly. Depending on the position of the fuselage, the abutment assembly 143 abuts different damping zones on the damping disc 130, thereby enabling the abutment assembly 143 to exert varying amounts of resistance on the damping disc 130, and thus enabling the damping mechanism 140 to exert varying amounts of resistance on the fuselage. This ensures that the resistance exerted by the damping mechanism 140 on the fuselage consistently partially offsets the gravity exerted on the arm by the fuselage, effectively improving the uniformity and rationality of the resistance distribution of the damping mechanism 140 on the fuselage.

[0136] For example, the thickness of the large damping area 1321 may be greater than the thickness of the small damping area 1322 , so that the resistance of the damping mechanism 140 to the large damping area 1321 may be greater than the resistance of the damping mechanism 140 to the small damping area 1322 .

[0137] By varying the thickness of different parts of the damping disc 130, the distance between the corresponding parts of the damping disc 130 and the fixed portion can be changed accordingly, thereby varying the resistance exerted by the damping mechanism 140 on the damping disc 130. Therefore, by making the thickness of the large damping region 1321 greater than the thickness of the small damping region 1322, the resistance exerted by the damping mechanism on the large damping region 1321 can be made greater than the resistance exerted on the small damping region 1322. This allows the abutment assembly 143 to exert varying degrees of resistance on the damping disc 130, and consequently, the damping mechanism 140 to exert varying degrees of resistance on the fuselage. This ensures that the resistance exerted by the damping mechanism 140 on the fuselage consistently partially offsets the weight of the fuselage on the arm, effectively improving the uniformity and rationality of the distribution of the resistance exerted by the damping mechanism 140 on the fuselage.

[0138] For example, the body can also have a second operating state. When the body is in the first operating state, the abutment assembly 143 can abut against the large damping area 1321. When the body is in the second operating state, the abutment assembly 143 can abut against the small damping area 1322. The first operating state is when the body is tilted, in which case the cleaning device can perform regular cleaning operations. The second operating state is when the body is lying flat, in which case the cleaning device can clean low areas (e.g., under a bed).

[0139] When the body is in a flat position for cleaning low areas, the body is closer to the ground, requiring less support, which in turn reduces the force on the arms. The coordination between the abutment assembly 143 and the damping plate 130 reduces the resistance exerted by the abutment assembly 143 on the damping plate 130, thereby balancing the load-bearing force exerted by the body on the arms and the resistance exerted by the damping mechanism 140. Furthermore, this resistance facilitates rotation of the body to a flat position, preventing excessive resistance from the damping mechanism 140, which could hinder the body from lying flat. This helps improve the reliability and stability of the body when in a flat position.

[0140] Among them, continue to see Figure 7 As shown, the distance between the small damping area 1322 and the fixing portion may gradually increase from one end of the small damping area 1322 close to the large damping area 1321 to the other end away from the large damping area 1321 .

[0141] As the abutment assembly 143 moves from the end of the small damping zone 1322 closer to the large damping zone 1321 toward the end farther from the large damping zone 1321, the distance between the small damping zone 1322 and the fixed portion gradually increases, which in turn causes the distance between the fixed portion and the damping disc 130 to gradually increase, gradually reducing the squeezing force of the abutment assembly 143 on the damping disc 130. Accordingly, the resistance of the damping mechanism 140 to the body also gradually decreases. That is, as the body switches from the first operating state to the second operating state, the resistance of the damping mechanism 140 to the body gradually decreases as the body gradually lies flat. This improves the smoothness of the change in the resistance of the damping mechanism 140 to the body, improves the balance between the resistance of the damping mechanism and the gravity of the body, helps to improve the smoothness of the body lying flat, and enhances the operability of the cleaning device.

[0142] For example, the thickness of the small damping zone 1322 can gradually decrease from one end close to the large damping zone 1321 to the end away from the large damping zone 1321. By gradually reducing the thickness of the small damping zone 1322, the distance between the damping disc 130 and the fixed portion can be gradually increased, thereby gradually reducing the squeezing force of the abutment assembly 143 on the damping disc 130. Correspondingly, the resistance of the damping mechanism 140 to the fuselage also gradually decreases. That is, during the process of the fuselage switching from the first working state to the second working state, as the fuselage gradually lies flat, the resistance of the damping mechanism 140 to the fuselage gradually decreases. This can improve the smoothness of the change in the resistance of the damping mechanism 140 to the fuselage, improve the balance between the resistance of the damping mechanism and the gravity of the fuselage, help improve the smoothness of the process of the fuselage lying flat, and enhance the operability of the cleaning equipment.

[0143] Continue to see Figure 7 As shown, the thickness of the large damping area 1321 can be d1, and the value of d1 can be 5 mm to 10 mm. For example, the value of d1 can be 5 mm, 8 mm, 10 mm, etc. This thickness range can make the distance between the large damping area 1321 and the fixed portion of the damping mechanism 140 relatively close, which can increase the extrusion force of the damping disc 130 on the damping mechanism 140 and improve the pressing force of the damping mechanism 140 on the damping disc 130. The damping mechanism 140 provides a greater resistance to the damping disc 130, so that this resistance can partially offset the weight of the fuselage in the corresponding state, thereby effectively reducing the weight of the fuselage on the hand.

[0144] The thickness of the small damping area 1322 at the end away from the large damping area 1321 can be d2, and the value of d2 can be 2 mm to 4 mm. For example, the value of d2 can be 2 mm, 3 mm, 4 mm, etc. This thickness range can make the distance between the small damping area 1322 and the fixed portion of the damping mechanism 140 relatively far, which can reduce the compression of the damping disc 130 on the damping mechanism 140 and reduce the pressing force of the damping mechanism 140 on the damping disc 130. The damping mechanism 140 provides a smaller resistance to the damping disc 130, so that the resistance can partially offset the weight of the fuselage in the corresponding state, thereby effectively reducing the weight of the fuselage on the hand.

[0145] Figure 8 This is a structural diagram of a damping mechanism 140 provided in an embodiment of the present application. Figure 9 This is an exploded view of a damping mechanism 140 provided in an embodiment of the present application. Figure 10 A cross-sectional view of a damping mechanism 140 provided in an embodiment of the present application.

[0146] Continue to see Figure 8 and Figure 9 As shown, the damping mechanism 140 may further include an elastic member 142, and the fixing portion may include a mounting base 141, which may be connected to the housing 110 and combined with the housing 110. Figure 10 As shown, the abutting assembly 143 can be slidably connected to the mounting base 141, one end of the elastic member 142 can be connected to the mounting base 141, and the other end can be connected to the abutting assembly 143, and the elastic member 142 can be in an elastically compressed state.

[0147] The mounting base 141 can provide mounting and fixing for the damping mechanism 140 so that the damping mechanism 140 can be mounted on the shell 110 through the mounting base 141 , which can reduce or avoid the displacement or shaking of the damping mechanism 140 in the shell 110 , and help to improve the reliability and stability of the damping mechanism 140 in the shell 110 .

[0148] The elastic member 142 can provide elastic force to the abutment assembly 143, so that the abutment assembly 143 can elastically expand and contract relative to the mounting base 141. For example, the elastic member 142 can be a spring member, or the elastic member 142 can be any other elastic structural member. The amount of compression of the elastic member 142 varies depending on the distance between the abutment point of the abutment assembly 143 and the damping disc 130 and the mounting base 141 (i.e., the fixed portion). This results in different amounts of elasticity applied by the elastic member 142 to the abutment assembly 143, thereby enabling the abutment assembly 143 to apply different amounts of resistance to the damping disc 130.

[0149] For example, when the abutting assembly 143 abuts the large damping area 1321, the large damping area 1321 is thicker, and the distance between the portion abutting the abutting assembly 143 and the mounting base 141 (i.e., the fixing portion) is smaller. Accordingly, the elastic member 142 is compressed more, so that the elastic member 142 can have a greater elastic force, thereby causing the abutting assembly 143 to exert a greater resistance on the damping disk 130.

[0150] Accordingly, when the abutment assembly 143 abuts the small damping area 1322, the thickness of the small damping area 1322 is relatively thin, and the distance between the abutment assembly 143 and the mounting base 141 (i.e., the fixing portion) is relatively large. Accordingly, the compression amount of the elastic member 142 is relatively small, resulting in a relatively small elastic force of the elastic member 142, and thus a relatively small resistance exerted by the abutment assembly 143 on the damping disk 130.

[0151] The elastic member 142 can push the abutment assembly 143 out of the mounting base 141, so that the abutment assembly 143 can always be in abutment contact with the damping disk 130, so that the abutment assembly 143 can always apply resistance to the damping disk 130, which can effectively reduce or avoid failure of the damping mechanism 140, thereby effectively improving the reliability and stability of the damping mechanism 140 on the fuselage.

[0152] Continue to see Figure 9 and Figure 10 As shown, the abutment assembly 143 may include a top ball 1431 and a top ball fixing member 1432. The top ball fixing member 1432 may be slidably connected to the mounting base 141, the top ball 1431 may be connected to the top ball fixing member 1432, and the other end of the elastic member 142 may be connected to the top ball fixing member 1432. The top ball 1431 may abut against the damping disk 130. During operation of the damping mechanism 140, the elastic member 142 may push the top ball fixing member 1432 to expand and contract, so that the top ball fixing member 1432 drives the top ball 1431 to expand and contract, thereby allowing the damping mechanism 140 to apply resistance to the damping disk 130 through the top ball 1431. The surface of the top ball 1431 is relatively round and smooth, which can prevent the fit between the abutment component 143 and the damping disk 130 from getting stuck, and helps to improve the smoothness of the fit between the abutment component 143 and the damping disk 130, and enhance the stability of the relative movement between the abutment component 143 and the damping disk 130.

[0153] Moreover, the spherical top ball 1431 can also reduce or avoid scratches, wear, etc. caused by the top ball 1431 on the damping disc 130, which helps to improve the protection of the damping disc 130 and extend the service life of the damping disc 130.

[0154] Continue to see Figure 9 and Figure 10As shown, the top ball fixing member 1432 may include a ball holder portion 14321 and a retaining portion 14322 disposed around the ball holder portion 14321. The ball holder portion 14321 and the retaining portion 14322 may be disposed together to form a receiving cavity, and the top ball 1431 may be located within the receiving cavity. The ball holder portion 14321 may provide a driving force for the top ball 1431, and the elastic force of the elastic member 142 may be transmitted to the top ball 1431 via the ball holder portion 14321, so that the top ball 1431 may be retracted and retracted. The retaining portion 14322 may provide a position limit for the top ball 1431, preventing the top ball 1431 from moving or shifting, thereby improving the reliability and stability of the connection between the top ball 1431 and the top ball fixing member 1432, and enhancing the overall structural stability of the abutment assembly 143.

[0155] Continue to see Figure 10 As shown, the retaining portion 14322 may be provided with a limiting protrusion 14323, which may be arranged around the inner ring of the retaining portion 14322 and located at an end of the retaining portion 14322 away from the ball holder 14321. The limiting protrusion 14323 may limit the position of the top ball 1431 in the axial direction of the retaining portion 14322, thereby reducing or preventing the top ball 1431 from axially dislodging from the retaining portion 14322, thereby improving the reliability and stability of the connection between the top ball 1431 and the top ball fixing member 1432, and enhancing the overall structural stability of the abutment assembly 143.

[0156] Continue to see Figure 9 and Figure 10 As shown, the mounting base 141 may include a fixed base 1411 and a spring fixing seat 1412, and the fixed base 1411 may be connected to the housing 110. The spring fixing seat 1412 may be located on a side of the fixed base 1411 facing away from the damping disc 130 and connected to the fixed base 1411, and the elastic member 142 may be connected to the spring fixing member.

[0157] The fixing base 1411 can provide a mounting for the damping mechanism 140 as a whole, so that the damping mechanism 140 can be installed in the housing 110 through the fixing base 1411. The spring fixing member can provide a mounting platform for the elastic member 142, so that the elastic member 142 can be connected to the fixing base 1411 through the spring fixing seat 1412, thereby achieving a connection between the elastic member 142 and the mounting base 141.

[0158] By decomposing the mounting base 141 into the fixed base 1411 and the spring fixing base 1412, the relatively complex mounting base 141 can be divided into the simpler fixed base 1411 and the spring fixing base 1412. This facilitates the production of the mounting base 141 and reduces the overall production difficulty and cost of the mounting base. Furthermore, it facilitates the installation of the elastic member 142 on the mounting base 141, reduces the difficulty of assembling the elastic member 142 and the mounting base 141, and thus improves the efficiency of the assembly between the elastic member 142 and the mounting base 141.

[0159] In the embodiment of the present application, the number of damping discs 130 and damping mechanisms 140 can both be two, and the two damping discs 130 and damping mechanisms 140 can be located on either side of the adapter 120. This allows the damping mechanisms 140 on either side of the adapter 120 to provide resistance to the fuselage, thereby helping to improve the balance and equilibrium of the overall force applied to the fuselage, reducing or preventing the fuselage from tilting due to uneven force, thereby improving the reliability and stability of the fuselage rotation.

[0160] The present application also provides a cleaning system, which may include a base station and cleaning equipment in any of the above scenarios. The base station can store and charge the cleaning equipment. For example, the cleaning equipment can be removed from the base station during use to perform cleaning operations. When the cleaning equipment is finished, it can be returned to the base station for storage.

[0161] Moreover, the base station can also charge the cleaning device. For example, the base station can be connected to a power source, and the cleaning device can be connected to the power source through the base station to realize charging of the cleaning device.

[0162] By including the above-mentioned cleaning equipment in the cleaning system, the user experience of the cleaning system can be effectively improved and the cleaning effect of the cleaning system can be enhanced.
