Description

Technical Field

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

[0002] With the development of science and technology and the improvement of people's living standards, cleaning equipment is being used more and more in people's lives.

[0003] Cleaning equipment includes robotic vacuum cleaners and handheld floor scrubbers. Taking handheld cleaning equipment as an example, users push or pull it forward to clean, but these devices are typically bulky, making them difficult to operate. Related technologies integrate hub motors into the wheels to assist movement; however, the hub motors and their associated control systems are expensive, significantly increasing the manufacturing cost of the cleaning equipment. Summary of the Invention

[0004] This application provides a walking device, a floor brush assembly, and a cleaning device, which helps to reduce the manufacturing cost of the cleaning device.

[0005] In a first aspect, this application provides a walking device, comprising: an axle; an elastic energy storage member having a first connecting end and a second connecting end, the first connecting end being mounted on the axle; and a walking component rotatably mounted on the axle, the walking component including a relatively fixed walking wheel and a buffer member, the buffer member being located between the elastic energy storage member and the walking wheel, the second connecting end abutting against the buffer member; wherein, the walking component rotates along a first direction to cause the elastic energy storage member to store energy; when the walking component rotates in the opposite direction along the first direction, the elastic energy storage member releases elastic force to assist the walking component in rotating in the opposite direction along the first direction.

[0006] According to the embodiments of this application, the walking device, by setting an elastic energy storage member and connecting its first connecting end to the wheel axle and its second connecting end to a buffer member, allows the elastic energy storage member to store force when the walking wheel, which is fixed relative to the buffer member, rotates in a first direction. When the walking component rotates in the opposite direction of the first direction, the elastic energy storage member releases the stored elastic force to assist the walking component in rotating in the opposite direction of the first direction. This provides assistance to the user when using the cleaning equipment, improving the effort-saving aspect of using the cleaning equipment and enhancing the user experience. It also avoids the use of a hub motor, thus reducing the manufacturing cost of the walking device. Simultaneously, the buffer member helps reduce the impact force transmitted from the elastic energy storage member to the walking wheel, thereby reducing noise during operation and further improving the user experience.

[0007] In one possible implementation of the first aspect of this application, when the walking device rotates along the first direction, the elastic energy storage member gradually tightens inward, and when it tightens to the point that the second connecting end is disengaged from the buffer, the elastic energy storage member can return to its original state and cause the second connecting end to continue to abut against the buffer.

[0008] In this design, the elastic accumulator has a limit to its tightening process; otherwise, if it tightens too much, it will affect the normal driving and movement of the floor scrubber. Therefore, when it reaches a certain level of coiling, the elastic accumulator will release, and the second connecting end will continue to contact the buffer. However, due to the presence of the buffer, the elastic accumulator will not produce excessive impact noise, and the impact force will not affect the normal use of the cleaning equipment.

[0009] In one possible implementation of the first aspect of this application, the walking component further includes a transmission assembly, which includes a ratchet and a pawl that cooperate with each other. The ratchet is fixed between the walking wheel and the buffer, and the pawl is rotatably disposed on the walking wheel. When the walking component rotates in the opposite direction of the first direction, the ratchet engages with the pawl.

[0010] In one possible implementation of the first aspect of this application, the walking component further includes a mounting base disposed within the walking wheel body. The mounting base has a mounting cavity, a portion of the wheel axle is located within the mounting cavity, the elastic energy storage member and the buffer member are located within the mounting cavity, and the buffer member is fixedly connected to the mounting base.

[0011] In one possible implementation of the first aspect of this application, the buffer is annular and surrounds the outer periphery of the axle.

[0012] In one possible implementation of the first aspect of this application, the buffer is detachably connected to the mounting base.

[0013] In one possible implementation of the first aspect of this application, either the inner circumferential surface of the mounting cavity or the buffer member is provided with a snap-fit ​​protrusion, and the other is provided with a snap-fit ​​groove that mates with the snap-fit ​​protrusion.

[0014] In one possible implementation of the first aspect of this application, the ratchet is fixed to one end of the mounting base along the axial direction of the wheel shaft, and the ratchet and the mounting base are integrally formed.

[0015] In one possible implementation of the first aspect of this application, one of the ratchet and the traveling wheel is provided with a fixing groove, and the other is provided with a fixing boss that mates with the fixing groove.

[0016] In one possible implementation of the first aspect of this application, the walking wheel is provided with a first limiting protrusion, which is located on the side of the pawl opposite to the ratchet.

[0017] In one possible implementation of the first aspect of this application, the elastic energy storage element includes a spiral spring, wherein the inner ring of the spiral spring is a first connecting end and the outer ring of the spiral spring is a second connecting end.

[0018] In one possible implementation of the first aspect of this application, the buffer member has at least one buffer groove on the side that is in contact with the mounting cavity.

[0019] Secondly, this application provides a floor brush assembly, including: a floor brush body; and a walking device, which is the aforementioned walking device, and the walking device is connected to the floor brush body.

[0020] Thirdly, this application provides a cleaning device, comprising: a body; and a floor brush assembly, which is the floor brush assembly as described in claim 13, wherein the floor brush assembly is movably connected to the body.

[0037] With the development of science and technology and the improvement of people's living standards, cleaning equipment is being used more and more in people's lives.

[0038] Cleaning equipment includes robotic vacuum cleaners and handheld floor scrubbers. Taking handheld cleaning equipment as an example, users push or pull it forward to clean, but these devices are typically bulky, making them difficult to operate. Related technologies integrate hub motors into the wheels to assist movement; however, the hub motors and their associated control systems are expensive, significantly increasing the manufacturing cost of the cleaning equipment.

[0039] To solve the above-mentioned technical problems, this application provides a walking device, a floor brush assembly, and a cleaning device.

[0040] The cleaning equipment according to embodiments of this application will be described below.

[0041] Cleaning equipment can be floor scrubbers. For example, cleaning equipment can be walk-behind floor scrubbers, semi-automatic floor scrubbers, etc.

[0042] The cleaning equipment 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 the surface of an object to be cleaned with different degrees of roughness. The embodiments of this application do not specifically limit the type of surface to be cleaned.

[0043] Please see Figure 1 The cleaning device 1000 provided in this application includes a floor brush assembly 200 and a body 100. The floor brush assembly 200 is rotatably connected to the bottom of the body 100. During cleaning, the user can hold the body 100 and push it to move the floor brush assembly 200 forward or backward on the surface to be cleaned, thereby enabling the floor brush assembly 200 to travel to different areas for cleaning.

[0044] Please see Figure 1 and Figure 2 The floor brush assembly 200 provided in this application may include a floor brush body 201 and a roller brush 203. The floor brush body 201 may serve as the main support structure of the floor brush assembly 200. The floor brush body 201 may have a receiving space, and the roller brush 203 is rotatably mounted in the receiving space, allowing the roller brush 203 to rotate about its own axial direction.

[0045] For example, there can be multiple roller brushes 203, and the multiple roller brushes 203 can be spaced apart in the travel direction of the floor brush assembly 200.

[0046] The outer side of the roller brush 203 may be provided with bristles or sponge, so as to scrub the ground during the rotation of the roller brush 203 and carry up the wastewater after cleaning.

[0047] The floor brush assembly 200 may also include a walking device 202. The walking device 202 is connected to the floor brush body 201. When the cleaning equipment 1000 is working, the walking device 202 contacts the surface to be cleaned and rolls along the surface to assist the cleaning equipment 1000 in walking on the surface to be cleaned, thereby improving the stability and reliability of the floor brush assembly 200 in walking on the surface to be cleaned.

[0048] The number of walking devices 202 can be multiple. "Multiple" means that the number of walking devices 202 can be two or more, and this application does not limit this.

[0049] Please continue to refer to the diagram. Figure 2 For example, there are two walking devices 202, which are symmetrically arranged on the brush body 201.

[0050] Along the travel direction of the floor brush assembly 200, the roller brush 203 can be installed at the front end of the floor brush body 201, and the traveling device 202 can be installed at the rear end of the floor brush body 201. This facilitates control of the travel direction of the floor brush assembly 200 and helps maintain the balance of the floor brush assembly 200 during travel. Furthermore, the roller brush 203 can preferentially contact the surface to be cleaned, and since there is no obstruction in front of the roller brush 203, it is beneficial for the roller brush 203 to clean the surface to be cleaned.

[0051] When a user uses the cleaning device 1000, in the direction of travel of the floor brush assembly 200, the rear end of the floor brush body 201 can be closer to the user, and the front end of the floor brush body 201 can be farther away from the user.

[0052] The cleaning device 1000 may also include a clean water tank. The clean water tank can be used to provide cleaning liquid to the roller brush 203 to wet the roller brush 203, so that the roller brush 203 can soak the stains on the surface to be cleaned during the cleaning process, reduce the adhesion of the stains, and thus make it easier to clean the stains from the surface to be cleaned.

[0053] The cleaning device 1000 may also include a wastewater tank. When the floor brush assembly 200 operates on the surface to be cleaned, dirt can be collected into the wastewater tank. The wastewater tank can be mounted on the floor brush assembly 200, which helps reduce wastewater and debris loss during transport, improving cleaning efficiency. It also allows users to directly empty the wastewater and debris after cleaning, thus reducing user steps and cleaning time.

[0054] The walking device 202 of the present application embodiment will be described below.

[0055] Please see Figure 3 and Figure 4 The walking device 202 provided in this application may include axle 1, elastic energy storage element 2 and walking component 3.

[0056] For example, the walking device 202 may also include a fixed bracket 5. The axle 1 can be connected to the floor brush body 201 through the fixed bracket 5. Specifically, the end of the axle 1 can be inserted into the fixed bracket 5, and the fixed bracket 5 is connected to the floor brush body 201. Thus, the walking device 202 can be connected to the floor brush body 201 as a separate module, which allows the walking device 202 to be assembled before being connected to the floor brush body 201, thereby improving the assembly efficiency of the floor brush assembly 200.

[0057] The connection between the wheel axle 1 and the fixed bracket 5 can be detachably achieved through fasteners, snap-fit ​​connections, or other means. This improves the maintainability of the walking device 202.

[0058] If the walking component 3 is rotatably mounted on the axle 1, then the walking component 3 can rotate relative to the axle 1.

[0059] The traveling component 3 may include a relatively fixed traveling wheel 31 and a buffer 32. Specifically, both the traveling wheel 31 and the buffer 32 are rotatably mounted on the axle 1. When the traveling wheel 31 rotates relative to the axle 1, the buffer 32 also rotates relative to the axle 1.

[0060] For example, the outer circumferential surface of the walking wheel 31 may be provided with a textured structure to increase friction. This reduces the likelihood of slippage in the walking device 202, thereby improving the user experience.

[0061] For example, the walking wheel 31 may include a wheel cover 311, a wheel body 312, and a wheel seat 313 connected in sequence. The wheel body 312 may have multiple insertion through holes and first connecting holes, which are spaced apart circumferentially on the wheel body 312. The wheel cover 311 has an insertion protrusion that engages with the insertion through holes and a second connecting hole. The wheel seat 313 has an insertion groove and a third connecting hole that are opposite to the insertion through holes. The insertion protrusion is inserted into the insertion groove, and fasteners pass through the first connecting holes, the second connecting holes, and the third connecting holes. Thus, by engaging the insertion protrusion with the insertion through holes and the insertion groove, the wheel cover 311 and the wheel seat 313 can be pre-fixed. Then, by passing fasteners through the first connecting holes, the second connecting holes, and the third connecting holes, the wheel cover 311, the wheel body 312, and the wheel seat 313 are fixed. The connection method is simple, which helps to improve the assembly efficiency of the walking device 202.

[0062] The elastic energy storage component 2 may have a first connecting end 21 and a second connecting end 22. The first connecting end 21 is mounted on the axle 1, and the second connecting end 22 abuts against the buffer component 32. The buffer component 32 may be located between the elastic energy storage component 2 and the walking wheel 31. By setting the buffer component 32, the noise generated during the movement of the walking device 202 can be reduced, thereby improving the user experience.

[0063] For example, a groove 12 may be provided on the end face of the axle 1, and the first connecting end 21 of the elastic energy storage member 2 may be wrapped around the outer peripheral surface of the axle 1 and pass through the groove 12.

[0064] For example, the material of the buffer 32 may include rubber, silicone, etc., and this application does not limit it.

[0065] For example, the elastic storage element 2 can be a torsion spring, a spiral spring, etc.

[0066] The walking component 3 rotates along the first direction F to allow the elastic energy storage component 2 to store energy. In the description of this application, when the walking component 3 rotates along the first direction F, the user pushes the cleaning device 1000 forward.

[0067] Specifically, when the user pushes the cleaning device 1000 forward, the walking wheel 31 can rotate relative to the axle 1 in the first direction F. Since the buffer 32 is fixed relative to the walking wheel 31, the buffer 32 also rotates in the first direction F, thereby driving the elastic energy storage member 2 to rotate in the first direction F, causing the elastic energy storage member 2 to undergo elastic deformation in the tangential direction of the axle 1, and the elastic energy storage member 2 begins to store energy.

[0068] It should be noted that the energy storage of the elastic energy storage component 2 can be periodic or can stop storing energy after reaching a preset value. This application does not limit this.

[0069] When the walking component 3 rotates in the opposite direction of the first direction F, the elastic storage component 2 releases its elastic force to assist the walking component 3 in rotating in the opposite direction of the first direction F. In the description of this application, when the walking component 3 rotates in the opposite direction of the first direction F, the user pulls the cleaning device 1000 backward.

[0070] Specifically, when the user pulls the cleaning device 1000 backward, the walking wheel 31 can rotate in the opposite direction of the first direction F relative to the axle 1. Since the elastic storage member 2 stores force when the walking component 3 rotates in the first direction F, when the walking wheel 31 rotates in the opposite direction of the first direction F, the elastic storage member 2 can release the stored elastic force to assist the buffer member 32 connected to the second connecting end 22 in rotating in the opposite direction of the first direction F. This assists the walking wheel 31, which is fixed relative to the buffer member 32, in rotating in the direction of the first direction F, thereby providing auxiliary power for pulling the cleaning device 1000 backward, which is beneficial to improving the user experience.

[0071] According to the embodiments of this application, the walking device 202, by setting an elastic energy storage member 2 and connecting its first connecting end 21 to the wheel axle 1 and its second connecting end 22 to the buffer member 32, allows the elastic energy storage member 2 to store energy when the walking wheel 31, which is fixed relative to the buffer member 32, rotates in the first direction F. When the walking component 3 rotates in the opposite direction of the first direction F, the elastic energy storage member 2 can release the stored elastic force to assist the walking component 3 in rotating in the opposite direction of the first direction F. This provides assistance to the user when using the cleaning equipment 1000, improving the effort-saving aspect of using the cleaning equipment 1000 and enhancing the user experience. It also avoids the use of a hub motor, thereby reducing the manufacturing cost of the walking device 202. Simultaneously, the buffer member 32 helps reduce the impact force transmitted from the elastic energy storage member 2 to the walking wheel 31, thus reducing noise during operation and further improving the user experience.

[0072] Please continue reading. Figure 3 and Figure 4 In some embodiments, when the walking device 202 rotates along the first direction F, the elastic storage member 2 gradually tightens inward, and when it tightens to the point that the second connecting end 22 is disengaged from the buffer member 32, the elastic storage member 2 can return to its original state and allow the second connecting end 22 to continue to contact the buffer member 32.

[0073] Therefore, the elastic accumulator 2 has a limit during the tightening process; otherwise, if the elastic accumulator 2 tightens further, it will affect the normal driving of the cleaning equipment 1000. Therefore, after being coiled to a certain extent, the elastic accumulator 2 will release, and the second connecting end 22 will continue to contact the buffer 32. Due to the presence of the buffer 32, the elastic accumulator 2 will not produce excessive impact noise, and the impact force will not affect the normal use of the cleaning equipment 1000.

[0074] Please continue reading. Figure 3 and Figure 4In some embodiments, the walking component 3 may further include a transmission assembly 4. The transmission assembly 4 may be connected between the walking wheel 31 and the buffer 32. The transmission assembly 4 is configured to restrict the reverse rotation of the buffer 32 along the first direction F when the walking component 3 rotates along the first direction F. Specifically, when the walking component 3 rotates along the first direction F and the elastic storage member 2 is periodically storing force, the elastic storage member 2 will release the stored elastic force instantaneously during the rotation of the walking component 3 along the first direction F. By setting the transmission assembly 4, the reverse rotation of the buffer 32 connected to the elastic storage member 2 along the first direction F can be avoided, thereby avoiding obstruction to the rotation of the walking component 3 along the first direction F. Alternatively, when the walking component 3 rotates along the first direction F and the elastic storage member 2 accidentally releases the stored elastic force due to vibration of the cleaning equipment 1000 or other reasons, the transmission assembly 4 prevents the walking component 3 from rotating in the reverse direction F as a whole, and allows the elastic storage member 2 to continue storing force or maintain maximum storage force.

[0075] Therefore, by setting the transmission component 4, the power transmission path between the walking wheel 31 and the buffer 32 can be controlled in one direction, thereby avoiding obstruction when the walking device 202 rotates along the first direction F, which is beneficial to ensuring the user experience.

[0076] Please continue reading. Figure 3 and Figure 4 In some embodiments, the transmission assembly 4 includes a ratchet 41 and a pawl 42 that cooperate with each other. The ratchet 41 is fixed between the traveling wheel body 31 and the buffer member 32, and the pawl 42 is rotatably disposed on the traveling wheel body 31. When the traveling component 3 rotates in the opposite direction of the first direction F, the ratchet 41 and the pawl 42 engage. This arrangement simplifies the structure and helps to reduce the manufacturing cost of the traveling device 202.

[0077] Specifically, when the user pushes the cleaning device 1000 forward, the walking wheel 31 and the buffer 32 rotate in the first direction F, and the elastic storage component 2 stores force. During the storage process of the elastic storage component 2, the pawl 42 slides across the tooth surface of the ratchet 41, and the ratchet 41 and the pawl 42 do not lock together. When the elastic storage component 2 releases the stored elastic force during the rotation of the walking component 3 in the first direction F, the ratchet 41 tends to rotate in the opposite direction under the drive of the elastic storage component 2. At this time, the pawl 42 engages in the tooth groove of the ratchet 41, achieving engagement and locking, and preventing the walking wheel 31 from rotating in the opposite direction F.

[0078] When the user pulls the cleaning device 1000 backward, the walking component 3 rotates in the opposite direction of the first direction F. The elastic force released by the elastic storage component 2 is transmitted to the ratchet 41 through the buffer component 32, causing the ratchet 41 to tend to rotate in the opposite direction of the first direction F. During the rotation of the walking wheel 31, the pawl 42 engages in the tooth groove of the ratchet 41 to achieve engagement and locking. This allows the torque released by the elastic storage component 2 to be transmitted to the walking wheel 31 through the buffer component 32, ratchet 41, and pawl 42, thereby assisting the walking wheel 31 to rotate in the opposite direction of the first direction F.

[0079] It should be noted that the ratchet 41 can also be connected to the traveling wheel 31, and the pawl 42 can be rotatably disposed between the traveling wheel 31 and the buffer 32.

[0080] Please continue reading. Figure 3 and Figure 4 In some embodiments, the walking component 3 may further include a mounting base 33. The mounting base 33 is disposed within the walking wheel 31. Exemplarily, the wheel cover 311, wheel body 312, and wheel seat 313 of the walking wheel 31 can enclose a fixed space, and the mounting base 33 can be installed within the fixed space. When assembling the mounting base 33, the mounting base 33 can be connected to the wheel seat 313 first, and then the wheel seat 313 can be connected to the wheel cover 311 and the wheel body 312, thereby reducing the assembly difficulty of the walking device 202. The wheel cover 311 can abut against the end face of the mounting base 33, thereby clamping the mounting base 33 together with the wheel seat 313. Thus, the axial movement of the mounting base 33 can be restricted by the wheel cover 311 and the wheel seat 313, thereby preventing the mounting base 33 from moving around in the fixed space during rotation, which helps to ensure the stability and reliability of the rotation of the walking device 202.

[0081] The mounting base 33 may have a mounting cavity 331, and a portion of the axle 1 is located within the mounting cavity 331. Specifically, the mounting base 33 is sleeved on the axle 1, so that a portion of the axle 1 passes through the mounting base 33 and enters the mounting cavity 331.

[0082] The elastic energy storage component 2 and the buffer component 32 are located within the mounting cavity 331. This provides protection for the elastic energy storage component 2 and the buffer component 32, thereby improving their service life.

[0083] For example, the mounting base 33 may include a mounting body 332 and a mounting cover 333, which together enclose a mounting cavity 331. The mounting body 332 and the mounting cover 333 can be detachably connected by snap-fit, which facilitates the maintenance of the elastic energy storage member 2 and the buffer member 32 located in the mounting cavity 331.

[0084] The buffer 32 can be fixedly connected to the mounting base 33. Thus, when the traveling component 3 rotates along the first direction F, the mounting base 33 rotates along the first direction F, causing the buffer 32 to rotate along the first direction F, thereby causing the elastic energy storage component 2 to store energy.

[0085] Please continue reading. Figure 4 and Figure 5 In some embodiments, the buffer 32 may be annular, surrounding the outer periphery of the axle 1. This allows the buffer 32 to provide a larger contact area for transmitting torque, while the annular structure also makes the force distribution more uniform, thereby helping to better reduce the noise generated by the elastic energy storage member 2.

[0086] Please continue reading. Figure 4 and Figure 5 In some embodiments, the buffer 32 is detachably connected to the mounting base 33. The detachable connection between the buffer 32 and the mounting base 33 can be achieved through snap-fit, fastener connection, magnetic attraction, or other methods.

[0087] This facilitates the replacement of the buffer component 32, thereby improving the maintainability of the walking device 202.

[0088] Please continue reading. Figure 4 and Figure 5 In some embodiments, one of the inner circumferential surface of the mounting cavity 331 and the buffer member 32 is provided with a snap-fit ​​protrusion 3321, and the other is provided with a snap-fit ​​groove 321 that mates with the snap-fit ​​protrusion 3321. Specifically, the inner circumferential surface of the mounting cavity 331 may be provided with a snap-fit ​​protrusion 3321, and the buffer member 32 may be provided with a snap-fit ​​groove 321 that mates with the snap-fit ​​protrusion 3321. Alternatively, the inner circumferential surface of the mounting cavity 331 may be provided with a snap-fit ​​groove 321, and the buffer member 32 may be provided with a snap-fit ​​protrusion 3321 that mates with the snap-fit ​​groove 321. Thus, when assembling the buffer member 32, the buffer member 32 can be pushed into the mounting cavity 331 along the axial direction of the wheel axle 1, so that the snap-fit ​​groove 321 mates with the snap-fit ​​protrusion 3321. This helps to reduce the assembly difficulty of the walking device 202, and at the same time, the structure is simple, which also helps to reduce the manufacturing cost of the walking device 202.

[0089] The number of snap-fit ​​grooves 321 and snap-fit ​​protrusions 3321 can be multiple. For example, the inner circumferential surface of the mounting cavity 331 is provided with four snap-fit ​​protrusions 3321 distributed circumferentially, and the outer circumferential surface of the buffer member 32 is provided with four snap-fit ​​grooves 321 corresponding one-to-one with the four snap-fit ​​protrusions 3321.

[0090] Please continue reading. Figure 4 and Figure 5In some embodiments, at least one buffer groove 322 is provided on the side of the buffer member 32 that is in contact with the mounting cavity 331. The buffer groove 322 can be an annular groove, an axial groove, or a localized pit, etc. The presence of the buffer groove 322 helps reduce the cross-sectional thickness or stiffness of the buffer member 32 at the buffer groove 322. When the buffer member 32 is subjected to an impact load, the buffer groove 322 is more likely to undergo elastic deformation, thereby absorbing the impact load and slowing down the rate and amplitude of impact transmission. This, in turn, improves the buffering effect and the ability of the buffer member 32 to absorb vibration and impact. Furthermore, when there are multiple buffer grooves 322, the deformation of the buffer member 32 can be more uniform.

[0091] It should be noted that the shape, depth, number and distribution of the buffer grooves 322 can be adjusted as needed, and this application does not limit them.

[0092] For example, multiple buffer grooves 322 may be present between two adjacent snap-fit ​​grooves 321. Thus, both the buffer grooves 322 and the snap-fit ​​grooves 321 can absorb the impact load, thereby further improving the buffering performance of the buffer member 32.

[0093] Please continue reading. Figure 4 and Figure 5 In some embodiments, the elastic energy storage component 2 includes a spiral spring. The inner coil of the spiral spring is the first connecting end 21, and the outer coil is the second connecting end 22. Thus, the spiral spring can store energy through the rotation of the buffer component 32 along the first direction F, thereby helping to reduce the manufacturing cost of the walking device 202. Simultaneously, the small size of the spiral spring facilitates optimization of the structural layout of the walking device 202, enabling its miniaturization.

[0094] The second connecting end 22 of the spring abuts against the buffer 32, meaning it can be connected to the buffer 32 through friction. Therefore, when the stored force of the spiral spring reaches its maximum value, the second connecting end 22 can disengage from the buffer 32, releasing the stored spring force. This allows the spiral spring to periodically store force and reduces its impact on the rotation of the walking device 202 along the first direction F.

[0095] Please continue reading. Figure 6 and Figure 7 In some embodiments, the ratchet 41 is fixed to one end of the mounting base 33 in the axial direction of the wheel axle 1. Exemplarily, the ratchet 41 may be located at the end of the mounting base 33 facing the wheel body seat 313.

[0096] The ratchet 41 and the mounting base 33 can be integrally molded. This improves the connection strength between the ratchet 41 and the mounting base 33, thereby ensuring the reliability of the meshing between the ratchet 41 and the mounting base 33. It also reduces the number of assembly steps in the traveling device 202, thus improving the assembly efficiency of the traveling device 202.

[0097] For example, the axle 1 may be provided with a shoulder 11, and the ratchet 41 may be fitted onto the shoulder 11. This facilitates the positioning of the mounting base 33, thereby further reducing the assembly difficulty of the walking device 202.

[0098] Please continue reading. Figure 6 and Figure 7 In some embodiments, one of the ratchet 41 and the traveling wheel 31 is provided with a fixing groove 411, and the other is provided with a fixing boss 315 that mates with the fixing groove 411. Specifically, the ratchet 41 may have a fixing groove 411, and the traveling wheel 31 may have a fixing boss 315. Alternatively, the traveling wheel 31 may have a fixing groove 411, and the ratchet 41 may have a fixing boss 315. Thus, by providing the fixing groove 411 and the fixing boss 315, the ratchet 41 can be reliably fixed to the traveling wheel 31, allowing the torque between the ratchet 41 and the traveling wheel 31 to be effectively transmitted. This also helps to reduce the axial dimension of the traveling device 202 in the wheel axle 1, thereby reducing the volume of the traveling device 202 and better optimizing the structural layout of the cleaning equipment 1000.

[0099] Please continue reading. Figure 7 In some embodiments, the traveling wheel 31 is provided with a first limiting protrusion 314. The first limiting protrusion 314 is located on the side of the pawl 42 opposite to the ratchet 41. Thus, when the rotation of the traveling device 202 causes the pawl 42 to not engage with the ratchet 41, the first limiting protrusion 314 can provide a limiting stop for the swing range of the ratchet 41, limiting the swing range of the ratchet 41 to a reasonable angle range, ensuring that when the ratchet 41 needs to be locked, the pawl 42 can quickly and accurately fall into the tooth groove.

[0100] For example, the pawl 42 may also be provided with a limiting groove 421 that mates with the first limiting protrusion 314. This allows for more accurate guidance and limiting of the swing of the pawl 42.

[0101] For example, the walking wheel 31 may also have a fixed notch, and the rotating end of the pawl 42 is rotatably mounted at the fixed notch. This facilitates the positioning of the pawl 42, thereby reducing the assembly difficulty of the walking device 202.
