[0091] The present application will be described below in conjunction with the drawings and specific embodiments:

[0092] Embodiment one:

[0093] As Figure 1 , 2As shown, the embodiment provides a cleaning tool, which comprises a rod body 1, a cleaning head 2 and a transmission device 3. The rod body 1 is generally a long rod, one end of which is connected with the combination of the cleaning head 2 and the transmission device 3, and the other end is held by the user to operate the cleaning tool in the application, which is convenient for the user to operate for a long time and reduces hand fatigue. The cleaning head 2 is provided with a main body 21 and a cleaning device 22, which is generally in a strip shape arranged on the side of the cleaning head 2, and is used to clean the surface to be cleaned such as the ground, wall and glass. For example, the cleaning device 22 can be provided with a scraping strip, a brush and a cloth strip, and various cleaning methods can be selected or combined according to different cleaning needs, which improves the applicability of the cleaning tool. The transmission device 3 is used to transmit the driving force on the rod body 1, which is movably arranged on the cleaning head 2 and rotationally connected to one end of the rod body 1 and drivingly connected with the cleaning device 22, that is, it has the ability to move relative to the cleaning head 2 to drive the cleaning device 22 on the cleaning head 2. The transmission device 3 can convert the force on the rod body 1 into driving force to drive the cleaning head 2 to move along the surface to be cleaned and acting force to drive the cleaning device 22 to act, that is, the necessary driving force in the cleaning tool can be completed by conventional mopping and sweeping actions. Specifically, when the cleaning head 2 is operated by the rod body 1, the lower side of the main body 21 will be against the surface to be cleaned. Therefore, when the transmission device 3 is driven by the rod body 1 to move along the cleaning device 22 in the direction (referred to as "first direction") in which the main body 21 is directed, the cleaning head 2 is also driven by the transmission device 3 to move in the first direction. Since the lower side of the main body 21 is against the surface to be cleaned, the resistance of the surface to be cleaned to the main body 21 will cause the force imbalance between the main body 21 and the cleaning device 22 on the cleaning head 2, so that the cleaning device 22 will protrude relative to the lower side of the main body 21, that is, the cleaning device 22 will also be driven by the transmission device 3 until it contacts the surface to be cleaned, thereby cleaning the surface to be cleaned during the movement of the cleaning head 2 in the first direction. The cleaning tool of the application has a simple structure, which only needs to adaptively improve the structure of the cleaning device 22 and the transmission device 3, that is, the transmission device 3 can meet the rotational connection of the cleaning head 2 and the rod body 1 to adapt to different angle cleaning requirements, and can also drive the cleaning device 22 to protrude below the main body 21, that is, the improvement of the transmission device 3 can simultaneously complete two design requirements.

[0094] Further, in the embodiment, the transmission device 3 is provided with a protruding portion 31 protruding from the upper side of the main body portion 21, and the protruding portion 31 is rotatably connected to one end of the rod body 1, that is, the rod body 1 can be rotated to a larger angle range relative to the cleaning head 2 through this design. In addition, the main body portion 21 is provided with a space 211 for the movement of the protruding portion 31, and the size of the space 211 in the first direction is greater than the size of the protruding portion 31, so that when the rod body 1 drives the transmission device 3 to displace relative to the main body portion 21, the main body portion 21 does not limit the movement of the protruding portion 31 in the first direction, so that the protruding portion 31 can move smoothly in the space 211. In addition, the size of the space 211 perpendicular to the first direction can also be limited, so that the space 211 can guide the movement of the protruding portion 31 to ensure the stability of the movement track of the protruding portion 31.

[0095] Specifically, as shown in Figure 2 the space 211 is an opening on the upper side of the main body portion 21, and the protruding portion 31 can protrude from the opening and be rotatably connected to the rod body 1. On the one hand, the protruding portion 31 needs to protrude from the upper portion of the main body portion 21, and on the other hand, the protruding portion 31 needs to have the requirement of being movable in the space 211. Therefore, the space 211 is designed as an opening structure on the upper side of the main body portion 21, which has a simple structure and can reduce the processing difficulty and production cost of the product while meeting various design requirements.

[0096] Further, in the embodiment, the transmission device 3 includes a transmission frame 32, the transmission frame 32 is connected to the protruding portion 31, and the main body portion 21 is specially provided with an inner cavity. The inner cavity can accommodate the transmission frame 32. On the one hand, by arranging the transmission frame 32 in the inner cavity of the main body portion 21, the transmission device 3 and the cleaning head 2 can be combined to provide good fixation and support for the transmission device 3 during work. On the other hand, the transmission device 3 can be connected to the cleaning device 22 in the first direction, that is, the transmission device 3 can protrude from the inner cavity or part of the cleaning device 22 can enter the inner cavity, so that the transmission device 3 can drive the cleaning device 22 when moving in the inner cavity. In addition, the space 211 can be provided on the upper side of the inner cavity for the protruding portion 31 to protrude, that is, only an opening needs to be formed on the upper side of the inner cavity, so that the structure is simplified.

[0097] Further, as shown in Figures 3-6As shown, in the embodiment, the driving of the cleaning device 22 by the transmission frame 32 is completed through the combination of the slot and the sliding block sliding in the slot. Specifically, the cleaning device 22 is provided with a chute 221, and the transmission frame 32 is provided with a push rod 321 penetrating in the chute 221 and being slidable along the chute 221. The chute 221 extends in the oblique direction along the first direction as a whole, that is, when the rod body 1 drives the transmission device 3 to move along the first direction, the push rod 321 also moves along the first direction. Since the chute 221 is obliquely angled with the first direction, the driving of the chute 221 by the push rod 321 can make the entire cleaning device 22 displace in the up-down direction of the main body 21 which is different from the first direction, so as to make the cleaning device 22 protrude from the lower side of the main body 21. Obviously, the positions of the chute 221 and the push rod 321 can be interchanged, that is, the chute 221 can be arranged on the transmission frame 32, and the push rod 321 is arranged on the cleaning device 22. When the cooperation of the chute 221 and the push rod 321 includes multiple, part of the chute 221 can be arranged on the cleaning device 22, and part of the chute 221 can be arranged on the transmission frame 32, and the push rod 321 is correspondingly arranged. First, the cooperation of the chute 221 and the push rod 321 has simple structure, low processing difficulty and high reliability, and can easily convert the driving of the transmission device 3 by the rod body 1 in the first direction into the movement of the cleaning device 22 in the up-down direction of the main body 21, so as to realize the automatic protrusion function of the cleaning device 22, without the need of additional complex driving mechanism, thereby reducing the cost and improving the reliability. In addition, the end of the chute 221 limits the driving range of the transmission device 3 to the cleaning device 22, so as to avoid the problems of jamming between related components or poor cleaning effect caused by the excessive movement range of the cleaning device 22.

[0098] Further, in the embodiment, since the driving force of the cleaning device 22 by the transmission device 3 is along the first direction, and then the movement direction of the cleaning device 22 is converted by the chute 221, in order to avoid unnecessary movement of the cleaning device 22 along the first direction, a guide limiting mechanism is arranged between the cleaning device 22 and the main body 21.

[0099] Specifically, as Figure 2 , 3In the embodiment, the guiding and limiting device is in the form of a guide column 214 and a guide hole 225, wherein the guide column 214 is arranged on the main body 21 and the guide hole 225 is arranged on the cleaning device 22, both of which extend along the up-down direction of the main body 21, and the guide column 214 penetrates into the guide hole 225, so that the guide column 214 and the guide hole 225 limit the movement of the cleaning device 22 in the first direction. Obviously, the positions of the guide column 214 and the guide hole 225 can be interchanged. In this way, the movement of the cleaning device 22 in the up-down direction of the main body 21 can be guided and limited in addition to the movement in the first direction, so as to ensure the reliability of the cleaning tool in the embodiment.

[0100] Further, in the embodiment, the main body 21 is in the form of a plate, which includes a length direction and a width direction, wherein the width direction is the first direction, so the cleaning device 22 extends along the length direction. When the main body 1 drives the cleaning head 2 to move along the first direction through the transmission device 3, the cleaning range of the cleaning device 22 along the length direction of the main body 21 is the cleaning range. Figure 5 Further, in the embodiment, the main body 21 is in the form of a plate, which includes a length direction and a width direction, wherein the width direction is the first direction, so the cleaning device 22 extends along the length direction. When the main body 1 drives the cleaning head 2 to move along the first direction through the transmission device 3, the cleaning range of the cleaning device 22 along the length direction of the main body 21 is the cleaning range.

[0101] Further, in the embodiment, in order to make the movement of the transmission rod 324 along the first direction more smooth, as shown in Figure 3 Further, in the embodiment, in order to make the movement of the transmission rod 324 along the first direction more smooth, as shown in

[0102] Further, in the embodiment, since the transmission frame 32 needs to be installed in the cavity of the main body 21, in order to facilitate assembly, as shown in Figure 3As shown, the main body 21 includes a detachable connection of the upper cover 217 and the bottom plate 218, and the upper cover 217 and the bottom plate 218 are buckled to each other, and an accommodation space for accommodating the transmission frame 32 is formed inside. The detachable design brings great convenience to the use and maintenance of the cleaning tool, and the detachable connection can be completed by means of screwing, clamping, inserting, bonding and the like, and the inner cavity formed between the upper cover 217 and the bottom plate 218 accommodates the transmission frame 32. The inner cavity provides a relatively closed space for the installation and operation of the transmission frame 32, which can effectively protect the transmission frame 32 from dust, debris and other interference, and facilitate maintenance of the transmission frame 32. In addition, in order to simplify the structure, the guide groove 216 is arranged on the bottom plate 218.

[0103] Further, in order to further reduce the production difficulty of the product and improve the maintainability, as shown in Figure 7 , the adapter plate 325 and the transmission rod 324 are detachably connected. Since the adapter plate 325 only needs to drive the transmission rod 324 to move in the first direction to achieve the effect of the product, the adapter plate 325 only needs to be clamped with the transmission rod 324 in the first direction, for example Figure 7 , the clamping mode in the figure, that is, the transmission rod 324 is provided with a groove-shaped part, so that the adapter plate 325 can be accommodated in the groove-shaped part. Of course, other ways such as screwing can also be used to clamp the two.

[0104] Further, as shown in Figure 3 , 5 , 7, the transmission device 3 further comprises a hinge head 34 rotatably connected to one end of the rod body 1 and rotatably connected to the transmission frame 32, so that the rod body 1 can have more freedom of movement relative to the cleaning head 2, realize movement transmission in different directions and angles, and meet the operation needs of users in different directions. It is particularly worth noting that the rotation axis direction of the hinge head 34 and the rod body 1 is perpendicular to the rotation axis direction of the hinge head 34 and the transmission frame 32. This perpendicular rotation axis design further enhances the flexibility and adaptability of the transmission system. In the actual cleaning process, different directions of rotation can make the cleaning tool better adapt to various cleaning environments, such as different sofa bottoms, wall joints, etc., and improve the cleaning effect.

[0105] Further, as shown in Figure 2As shown, the cleaning device 22 includes two, and is separately arranged on both sides of the main body 21 along the first direction, and the directions of the inclined grooves 221 on the two cleaning devices 22 are opposite, that is, the transmission frame 32 has two ends extending out along the first direction and is connected with one cleaning device 22 respectively, so that when the lower side of the main body 21 is abutted on the surface to be cleaned and the cleaning head 2 is moved along the first direction by the rod body 1, the transmission device 3 will be displaced relative to the main body 21 with the movement of the rod body 1. During this process, due to the connection relationship between the transmission device 3 and the cleaning device 22, the transmission device 3 can drive the cleaning device 22 behind the main body 21 to protrude from the lower side of the main body 21. This enables the cleaning device behind to timely process the area that has been cleaned, such as wiping the remaining stains, etc., to further improve the cleaning quality. At the same time, due to the opposite directions of the inclined grooves 221 on the two cleaning devices 22, the transmission device 3 can also drive the cleaning device 22 in front of the main body 21 to retract from the lower side of the main body 21. Such a design can avoid unnecessary interference of the cleaning device 22 in front to the area that has not been cleaned or dirt the cleaning device 22 in front of the main body 21 during the cleaning process, and also can make the cleaning tool move more smoothly and reduce resistance. Through the cooperative action of the front and rear cleaning devices, an efficient and accurate cleaning process can be realized to meet the needs of different cleaning scenes.

[0106] Further, as shown, Figure 8 The cleaning device 22 includes a loading part 226 connected with the transmission frame 32 and a cleaning part 227 detachably connected with the loading part 226. The advantage of such a design is that when the cleaning part 227 is worn out or needs to be replaced with different types of cleaning parts to adapt to different cleaning tasks, it only needs to be detached from the loading part 226 and then a new cleaning part is installed, which is convenient, fast and low in cost. The connection between the loading part 226 and the transmission frame 32 ensures that the cleaning part can stably follow the movement of the transmission device during work to ensure the continuity and effectiveness of the cleaning work. Through such a detachable structure, the user can flexibly adjust the configuration of the cleaning device according to the actual needs, improve the versatility and applicability of the cleaning tool, and meet the needs of different users in different cleaning scenes.

[0107] Specifically, the cleaning part 227 is a scraping strip or a brush. These two different types of cleaning parts provide diversified cleaning options for the cleaning tool. The scraping strip is suitable for removing hard stains or dirt or a small amount of water stains on the surface to be cleaned, and can remove them from the surface to be cleaned by scraping; the brush is more suitable for cleaning some fine dust or lint, and its soft bristles can gently wipe the surface to avoid damaging the surface.

[0108] Meanwhile, the bottom surface of the main body 21 is detachably provided with a wiping material or a friction block. The detachable design can allow the user to replace different wiping materials or friction blocks according to different cleaning requirements, so as to adapt to various materials of the surface to be cleaned. On the other hand, the wiping material can be used to wipe the surface to be cleaned, and the cleaning part 227 at the rear of the main body 21 is a scraping strip, which can clean the residual water stains on the surface to be cleaned after wiping.

[0109] Further, as shown in the drawings, Figure 9 The cleaning tool in the embodiment further includes a scraping device 4 slidingly arranged on the rod body 1, so as to clean the cleaning head 2. Specifically, the design can make the cleaning tool more comprehensively process the cleaning head 2 during the cleaning process. The cleaning head 2 is shaped like a plate, which is beneficial to fully contact with the surface to be cleaned during the cleaning process, thereby improving the cleaning efficiency. When the transmission device 3 drives the cleaning head 2 to rotate to the length direction of the cleaning head 2 being parallel to the length direction of the rod body 1, the scraping device 4 can be moved along the length direction of the rod body 1 to scrape the bottom surface of the cleaning head 2. During the process, the scraping device 4 can effectively remove the stains, dust and other impurities remaining on the bottom surface of the cleaning head 2, so as to maintain the cleanliness of the cleaning head, thereby ensuring that the cleaning tool can continuously maintain good performance during the subsequent cleaning work, and further improving the cleaning effect and quality.

[0110] Further, as shown in the drawings, Figure 10 The scraping device 4 is provided with a scraping piece 41 facing the rod body 1, which provides a scraping function for the cleaning process of the cleaning tool. When the cleaning device 22 includes two and is arranged on both sides of the main body 21 along the first direction, the length of the scraping piece 41 does not exceed the distance between the two cleaning devices 22. This design ensures that the scraping piece 41 will not exceed the range of the cleaning device 22 during work, thereby avoiding the situation that the scraping piece 41 is clamped with the cleaning device 22 due to the protrusion of the cleaning device 22 from the bottom side of the main body 21.

[0111] Embodiment two:

[0112] The difference between the above embodiment and the present embodiment is that, as shown in the drawings, Figure 11 , 12 In the present embodiment, the guide limiting device includes a guide hole 213 arranged on the main body 21 and opening downward, and a guide plate 224 arranged on the cleaning device 22 and extending upward. The guide plate 224 penetrates into the guide hole 213, and the movement of the guide plate 224 in the first direction is limited by the guide hole 213, so as to ensure that the cleaning device 22 can only move along a specific direction, thereby avoiding the situation of deviation or shaking, and ensuring the stability and accuracy of the cleaning work.

[0113] In addition, in the embodiment, the cleaning device 22 is provided with a chute 221, the transmission frame 32 is provided with a push rod 321 arranged in the chute 221, and the chute 221 extends in the first direction and upwardly. The chute 221 has at least two, and the push rod 321 is shaped as a rod body arranged in the chute 221 and through the end portions of the transmission rods 324 in the length direction of the main body 21. The integrated design ensures the continuity and stability of the transmission, reduces the detachable arrangement of the push rod 321 and the transmission frame 32, reduces the complexity of the components, and reduces the processing cost.

[0114] Embodiment three:

[0115] The difference from the above embodiment is that, as shown in Figure 13 、 14 , the transmission device 3 of the cleaning tool further includes a transmission member 33, which is in a movable connection relationship with the end portion of the transmission frame 32 in the first direction and is also in a movable connection with the cleaning device 22. The transmission member 33 is rotatably connected to the main body 21. The rotatable connection allows the transmission member 33 to perform relative rotational movement on the main body 21. When the rod body 1 starts to drive the transmission device 3 to displace relative to the main body 21, due to the movable connection between the transmission frame 32 and the transmission member 33 and the rotatable connection between the transmission member 33 and the main body 21, the transmission frame 32 drives the transmission member 33 to rotate relative to the main body 21. With the rotation of the transmission member 33, the cleaning device 22 can be further driven to protrude from the lower side of the main body 21. The cleaning device 22 is driven in a rotating manner, which avoids the poor use caused by the frictional resistance when the push rod 321 is used in sliding cooperation with the chute 221 in the above embodiment, and can further improve the user experience.

[0116] Specifically, as shown in Figure 14 、 15As shown, the transmission member 33 comprises a rotating portion 331 which is rotationally coupled with the main body 21, and a first coupling portion 332 and a second coupling portion 333 which are respectively limitedly coupled with the transmission frame 32 and the cleaning device 22, that is, the transmission member 33 is similar to a triangle or Y-shaped structure, and the three extending portions are respectively connected with the main body 21, the transmission frame 32 and the cleaning device 22. Since the transmission member 33 is rotationally coupled with the main body 21, when the transmission frame 32 moves along the first direction, the first coupling portion 332 drives the whole transmission member 33 to rotate around the rotating portion 331, so that the second coupling portion 333 drives the cleaning device 22 to extend out of the lower side of the main body 21. In order to ensure that the transmission member 33 does not get stuck during rotation, at least one of the rotational coupling between the transmission member 33 and the main body 21 and the limited coupling between the transmission member 33 and the transmission frame 32 is clearance fit, so that the whole cleaning tool is more stable and smooth during operation.

[0117] Specifically, as shown in the figure, Figures 15-18 the first coupling portion 332 is shaped like a rod, and the end of the transmission frame 32 along the first direction is provided with a hook 322 which can hook the first coupling portion 332, and the opening of the hook 322 faces downward, which makes the hook 322 push the first coupling portion 332 when the transmission frame 32 moves along the first direction. Since the first coupling portion 332 and the rotating portion 331 cannot be collinear along the first direction, the movement of the first coupling portion 332 along the first direction can drive the rotation of the transmission member 33, so as to realize the extension of the cleaning portion 227. The use of the hook 322 can make the assembly of the first coupling portion 332 simple, and of course, other ways such as sliding block and sliding groove, connecting rod, etc. can also be used, but these ways either increase the number of parts or are inconvenient to assemble. In the embodiment, as shown in the figure, Figure 16 when the transmission rod 324 is provided with multiple hooks 322, the number of hooks 322 is also set to multiple and arranged at the end of the transmission rod 324, and the first coupling portion 332 can be shaped like a rod or multiple rod segments which pass through the multiple hooks 322, so that the driving of the transmission device 3 to the cleaning assembly 22 is more uniform. In addition, as shown in the figure, Figure 20 since the cooperation between the hook 322 and the first coupling portion 332 can be clearance fit, and the opening of the hook 322 faces downward, the main body 21 is also provided with a bearing rib 219, and the upper side of the bearing rib 219 is shaped like an open arc-shaped bearing groove 2191 which extends along the first direction, so that the first coupling portion 332 cannot be pulled out of the hook 322 at will, and the rotation of the transmission member 33 is guided to a certain extent.

[0118] In addition, as shown in the figure, Figures 17-19As shown, the upper part of the cleaning device 22 is provided with a matching groove 222, the side of the matching groove 222 faces the direction of the transmission member 33 to form an opening, so that the second matching part 333 can be inserted into the matching groove 222, and thus when the transmission member 33 rotates, the second matching part 333 can be driven by the wall surface of the matching groove 222 to move the cleaning device 22 in the up-down direction of the main body part 21. The connection in this way forms a clearance fit between the transmission member 33 and the cleaning device 22, providing a large amount of movement for the transmission member 33 to drive the cleaning device 22 to move, avoiding structural jamming, and smoothly driving the cleaning device 22 to move in the up-down direction, and the assembly method is simple.

[0119] In addition, in the embodiment, as shown in Figure 17 、 18 , a guide limiting device different from the above-mentioned embodiments is also provided, which includes a mounting groove 212 provided on the main body part 21 and opening downward, and a mounting bracket 223 provided on the cleaning device 22, the mounting groove 212 extends along the length direction of the main body part 21, and the mounting bracket 223 is arranged in the mounting groove 212 to limit the movement of the mounting bracket 223 in the first direction by the two wall surfaces of the mounting groove 212 in the first direction. In fact, it is the same as the guide limiting device in the above-mentioned embodiments, but by arranging the mounting bracket 223 in the mounting groove 212, the main body part 21 can cover the cleaning device 22 from the upper side, so that the entire cleaning head 2 has better visual integrity, improving the user experience and increasing the product competitiveness.

[0120] Embodiment Four:

[0121] Different from the above-mentioned embodiments, as shown in Figure 21 、 22 , the allowance space 211 also includes a containing cavity protruding from the upper side of the main body part 21, that is, the opening of the allowance space 211 on the upper side of the main body part 21 also has an extension of the main body part 21, and forms a containing cavity. When the protruding part 31 protrudes from the upper side of the main body part 21, that is, the part protruding from the opening of the allowance space 211 is located in the containing cavity, and the transmission bracket 32 is rotationally connected to the main body part 21 through the protruding part 31. When the rod body 1 drives the transmission device 3 to displace relative to the main body part, the protruding part 31 rotates in the containing cavity of the allowance space 211, and then drives the cleaning device 22 to protrude from the lower side of the main body part 21 through the transmission bracket 32. In this embodiment, the transmission member 33 in the third embodiment is not needed, that is, only the rod body 1 drives the protruding part 31 to rotate relative to the main body part 21, which can realize the swinging of the transmission bracket 32, so that the cleaning device 22 can displace in the up-down direction of the main body part 21, further reducing the number of parts and the product cost.

[0122] Specifically, in order to further reduce the assembly difficulty of the product, as shown inFigure 25 , 26 As shown, in this embodiment, the rotatable connection between the protrusion 31 and the main body 21 is a shaft and shaft hole fit. The protrusion 31 is provided with a rotating shaft 312, and the upper cover 217 and the bottom plate 218 of the main body 21 are provided with a shaft hole. The upper cover 217 is provided with an upper half shaft hole 2171, and the bottom plate 218 is provided with a lower half shaft hole 2181. The upper half shaft hole 2171 and the lower half shaft hole 2181 are closed to form the shaft hole with the rotating shaft 312. This arrangement is simple to assemble. That is, you only need to attach the protrusion 31 to the lower half shaft hole 2181 and then fasten the upper cover 217 to the bottom plate 218 to complete the closure of the upper half shaft hole 2171 and the lower half shaft hole 2181.

[0123] Furthermore, such as Figures 21-23 As shown, the transmission device 3 is equipped with a hinge head 34, which is rotatably connected to one end of the rod 1, allowing the angle between the rod 1 and the cleaning head 2 to be adjusted. Additionally, the hinge head 34 can cooperate with the protrusion 31. When it is necessary to drive the cleaning device 22, the hinge head 34 can abut against the protrusion 31, causing the protrusion 31 to rotate relative to the main body 21, producing a pendulum-like effect. This method of using the hinge head 34 to drive the protrusion 31 only requires modification of the hinge head 34 in the above embodiment, without adding new components. Necessarily, the contact point between the hinge head 34 and the protrusion 31 is located below the rotatable connection point between the protrusion 31 and the main body 21, so that when the rod 1 drives the hinge head 34 to move in the first direction, it can drive the cleaning device 22 located behind the main body 21 to move downwards from the main body 21. Specifically, the hinge head 34 includes a driving part 341, and the protrusion 31 is provided with a driven part 311 that abuts and cooperates with the driving part 341. When the rod 1 drives the hinge head 34 to move in the first direction, the driving part 341 can abut against the driven part 311, thereby driving the protrusion 31 to rotate.

[0124] In this embodiment, the driving part 341 is formed into a rod shape and can move along the first direction, while the driven part 311 is formed into a swing arm located on the side of the driving part 341 along the first direction. This design can increase the coverage area of ​​the driving part 341 in the moving direction when the driving part 341 moves, thereby preventing the possible disengagement of the driving part 341 from the driven part 311 due to the gap between the components of the product, and ensuring the reliability of the product.

[0125] Furthermore, such as Figure 22As shown, the driven part 311 is shaped as two swing arms which are respectively arranged on the two sides of the driving part 341 along the first direction and are integrally connected at the upper part, the main body part 21 is provided with a sliding groove 215 which is open upward, and the driving part 341 is a cylindrical rod, so that the end of the driving part 341 can be clamped between the driven part 311 and the sliding groove 215, so that the hinge head 34 can rotate relative to the protruding part 31, that is, the combination of the hinge head 34 and the rod body 1 can rotate relative to the cleaning head 2, and the rod body 1 and the hinge head 34 are rotationally connected, so as to provide more directions for the relative rotation of the rod body 1 and the cleaning head 2, that is, increase the degree of freedom of the cleaning head 2 on the rod body 1, so as to better adapt to various cleaning environments.

[0126] In the present example, the sliding groove 215 has a certain length along the first direction, that is, when the driving part 341 passes through the protruding part 31 and extends into the sliding groove 215, it can move in the sliding groove 215 when receiving the driving of the rod body 1, so that the driving part 341 can abut against the driven part 311 when moving in the sliding groove 215, or can be separated from the driven part 311 to reset the cleaning device 22.

[0127] Further, as shown in Figure 21 、 23 , the sliding groove 215 and the driven part 311 each include two, the driving part 341 extends from both ends of the hinge head 34 and cooperates with one driven part 311 and one sliding groove 215 respectively, so that the hinge head 34 can be stably connected to the protruding part 31 and the main body part 21, and when the driving part 341 drives the driven part 311, the force balance of the protruding part 31 is ensured, so as to ensure the stable driving of the cleaning device 22.

[0128] In the present example, in order to ensure that the extension range of the cleaning device 22 is appropriate, and in order to avoid collision between the protruding part 31 and the transmission frame 32 and other components during rotation, a rotation limiting device is further arranged between the transmission member 33 and the main body part 21 to limit the rotation range of the protruding part 31.

[0129] Specifically, as shown in Figure 21 、 24 , the rotation limiting device includes a limiting hole 323 on the transmission frame 32 and a limiting protrusion 23 on the main body part 21, the limiting protrusion 23 penetrates into the limiting hole 323, and the size of the limiting hole 323 along the first direction is greater than the size of the limiting protrusion 23, that is, it can meet the rotation of the limiting protrusion 23 in the limiting hole 323 when the transmission frame 32 rotates, and the inner wall of the limiting hole 323 along the first direction can limit the rotation range of the limiting protrusion 23, that is, the rotation of the transmission frame 32 can be limited, and the cooperation of the limiting protrusion 23 and the limiting block 323 can be provided with multiple groups to reduce the requirement for the strength of the components when a single group cooperates. In addition, as shown in Figure 22As shown, the rotation limiting device can also be configured as the end of the slide groove 215 and the part of the drive unit 341 located within the slide groove 215. When the drive unit 341 moves to abut the end of the slide groove 215, the drive of the drive unit 341 on the driven part 311 stops, thus limiting the rotation amplitude of the protrusion 31 and the transmission frame 32. The above two rotation limiting devices can be used individually to reduce structural complexity, cost, and processing difficulty, or they can be used in combination to improve the reliability of rotation limiting.

[0130] In this embodiment, since the rotation of the transmission frame 32 can directly drive the cleaning device 22 to move in the vertical direction of the main body 21, the end of the transmission frame 32 along the first direction can be directly fixedly connected to the cleaning device 22. That is, a number of transmission rods 324 can be provided on the transmission frame 32, and the cleaning device 22 can be directly fixedly installed at the end of the transmission rod 324. This fixed installation can be integrally formed or connected by fasteners or locking parts.

[0131] Example 5:

[0132] The difference from Example 4 is that, as Figure 27 As shown, in this embodiment, the driven part 311 is formed as a hole on the protrusion 31, and the driving part 341 is formed as a rod passing through the driven part 311. By using the cooperation of the hole and the rod, noise caused by collision between the driven part 311 and the driving part 341 when not in use can be avoided, thereby improving the user experience.

[0133] In addition, in this embodiment, the hinge head 34 also includes a hinge head body 342 that is rotatably connected to the drive part 341, so that when the drive part 341 is not rotating smoothly relative to the protrusion 31, the rotational freedom of the rod body 1 relative to the cleaning head 2 can be guaranteed by the rotation of the drive part 341 and the hinge head body 342.

[0134] Specifically, such as Figure 27 As shown, the hinge head body 342 is provided with a through hole 3421, and the drive part 341 is a cylindrical rod that passes through the through hole 3421. The through hole 3421 is a through hole, so that both ends of the drive part 341 can extend out from it, so that both ends of the drive part 341 can cooperate with the protrusion 31 and the slide groove 215.
