Technical Field

[0001] The utility model relates to the field of floor cleaning, and particularly to a cleaning device for cleaning the floor. Background Art

[0002] For existing cleaning devices, such as floor scrubbers, floor polishers, etc., in order to achieve a better cleaning effect on the floor, there is a structure that sets two cleaning cylinders made of different materials to independently clean the floor respectively, which can better meet the user's cleaning needs for the floor. However, for the scraping structure set for the two cleaning cylinders, when scraping sewage and dirt from the two cleaning cylinders respectively, it is unable to form a good scraping structure, resulting in the scraping structure being prone to leaving residual sewage and dirt during the process of interfering with or contacting the two cleaning cylinders for scraping. It is unable to keep the two cleaning cylinders in a clean state well, and unable to clean the two cleaning cylinders well with the clean water structure supplied in combination with the scraping structure. In this way, the residual sewage and dirt on the two cleaning cylinders are likely to cause secondary pollution to the floor, resulting in a poor cleaning effect on the floor and a poor user experience effect. Summary of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems in the above related technologies to a certain extent.

[0004] For this reason, the purpose of the utility model is to provide a cleaning device, mainly to solve the problem that the scraping structure in the existing cleaning device cannot effectively scrape sewage and dirt from two cleaning cylinders made of different materials respectively.

[0013] When the second cleaning component and the cover member are installed in place, the cover member forms a pressing structure in contact with the upper end surface of the scraping member, causing the scraping member to be in contact with the outer surface of the second cleaning cylinder to scrape off dirt.

[0014] For the aforementioned cleaning equipment, the scraping member is configured to be installed on the equipment main body through an elastic member. When the scraping member forms an interference structure with the first cleaning cylinder, the elastic member is in a compressed structure. When the scraping member forms a contact pressing structure with the second cleaning cylinder, the elastic member is in an uncompressed structure.

[0015] For the aforementioned cleaning equipment, it is set that when the first cleaning cylinder is installed in place, it is configured to be rotatable and rollable around the axis N in the cylinder cavity. It is set that when the second cleaning cylinder is installed in place, it is also configured to be rotatable and rollable around the axis N in the cylinder cavity.

[0018] For the aforementioned cleaning equipment, the protruding structure of the scraping member is configured to be vertically distributed, so that the scraping member is configured to be movable in the vertical direction;

[0019] Alternatively, the convex structure of the scraping member is arranged to face the central position of the cross-section of the first cleaning cylinder or the second cleaning cylinder in the radial direction and to gradually protrude downward in an inclined structure so that the scraping member is configured to be movable in the inclined direction.

[0020] For the aforementioned cleaning device, the thickness value formed by the scraping member in the rotational rolling direction is arranged to gradually decrease along the protruding direction, and the end position of the scraping member is arranged to be an arc-shaped structure in the rotational rolling direction.

[0023] For the aforementioned cleaning device, a channel portion is provided on the device main body, at least a part of the scraping member is located in the channel portion for movement, and when the scraping member moves, the two side surfaces of the scraping member in the rotational rolling direction are arranged not to contact the channel wall of the channel portion simultaneously.

[0024] Compared with the prior art, the present utility model has the following beneficial effects:

[0025] In this solution, the first cleaning assembly and the second cleaning assembly can be replaced and installed with each other, which can better meet the user's cleaning requirements for the ground. Only manual replacement is needed to achieve different cleaning effects on the ground, improving the user experience effect.

[0026] In this solution, only a single scraping member needs to be provided to separately and independently scrape sewage and dirt from the first cleaning cylinder and the second cleaning cylinder. The overall structure is simple and the cost is low. At the same time, the sewage and dirt on the first cleaning cylinder and the second cleaning cylinder can be better scraped and separated.

[0027] In this solution, the scraping member is arranged to be movable in the protruding direction. Only by the cooperation of the cover member and the cushion portion, the user can achieve the movement effect of the scraping member when installing the cover member. The movable structure of the scraping member can better separately and independently adapt to the first cleaning cylinder and the second cleaning cylinder for scraping dirt, and achieve better effects of scraping sewage and dirt from the first cleaning cylinder and the second cleaning cylinder.

[0028] In this solution, after the scraping member moves along the convex direction, a longer convex structure can be formed in the cylinder cavity. The longer length of the convex structure can better extend into the inner side of the outer surface of the first cleaning cylinder to form an interference structure, and an interference structure with a deeper interference depth is formed, thereby achieving a better effect of scraping sewage from the first cleaning cylinder.

[0029] In this solution, when the scraping member is in the initial position, a relatively short convex structure can be formed in the cylinder cavity. The relatively short length of the convex structure can better contact and press against the outer surface of the second cleaning cylinder to form a relatively contacting and scraping structure, thereby achieving a better effect of scraping sewage from the second cleaning cylinder. At the same time, the stability of the second cleaning cylinder during rotational rolling motion is better.

[0030] In this solution, when the scraping member does not contact the pad portion, at this time, under the action of the elastic member, the scraping member returns to the initial position. At this time, the length of the convex structure formed by the scraping member extending in the cylinder cavity is relatively shorter. At this time, the scraping member can better contact and press against the outer surface of the second cleaning cylinder to scrape off dirt. At the same time, because the depth of contact and pressure is relatively small, the dirt adhering to the outer surface of the second cleaning cylinder can be better scraped off, and the rotational rolling motion of the second cleaning cylinder is more stable, and it is not easy to have problems such as jamming or bouncing during the rolling motion.

[0031] In this solution, the structure of the scraping member enables the scraping member to move stably on the device main body and move back to its original position under the elastic force of the elastic member. Only by setting a cover member can the scraping member be pressed and fixed by the cover member at two positions formed during movement, which is convenient for users to operate and use, without the need to replace the scraping member or the cover member, and the operation is simpler.

[0032] In this solution, the structures of the first cleaning cylinder and the second cleaning cylinder enable the first cleaning cylinder to better contact and fit the ground to form a large-area and large-friction cleaning effect of close contact and fit, and the second cleaning cylinder can better contact the ground to form a large-friction scraping and cleaning effect.

Detailed implementation manners

[0038] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0039] Embodiment: The cleaning equipment of the present utility model, as Figures 1 to 4 shown in the composition, the cleaning equipment mainly realizes the cleaning effect on the ground, can better meet the user's cleaning requirements for the ground, and at the same time can greatly improve the situation of secondary pollution to the ground, and overall improve the cleaning effect on the ground.

[0040] A cleaning equipment of this solution includes an equipment main body 1, and the equipment main body 1 moves on the ground to realize the cleaning treatment of the ground. Among them, a cylinder cavity 101 is provided on the equipment main body 1, and the cylinder cavity 101 has a structure with an open lower part. It also includes a first cleaning component 2 and a second cleaning component 3. The first cleaning component 2 and the second cleaning component 3 are arranged to be interchangeably installed in the cylinder cavity 101. The user can choose to install the first cleaning cylinder 201 or the second cleaning cylinder 301 in place according to the cleaning requirements for the ground, and the user can interchange them during the cleaning process to better achieve different cleaning effects on the ground.

[0041] Among them, the first cleaning component 2 is provided with a first cleaning cylinder 201 having a water-absorbing structure to absorb sewage when the first cleaning cylinder 201 cleans the ground. The second cleaning component 3 is provided with a second cleaning cylinder 301 having a water-repellent structure to scrape and drive the sewage without absorbing the sewage when the second cleaning cylinder 301 cleans the ground.

[0042] Among them, a difference value L is set between the outer diameter values respectively formed by the first cleaning cylinder 201 and the second cleaning cylinder 301 in their non-deformed structures. L is greater than or equal to 0 and less than or equal to 4 millimeters. Both the first cleaning cylinder 201 and the second cleaning cylinder 301 are in a cylindrical structure, being a hollow or through cylindrical structure. By limiting the difference value between their outer diameter values, both the first cleaning cylinder 201 and the second cleaning cylinder 301 can better contact the ground for cleaning treatment, preventing the problem that the first cleaning cylinder 201 or the second cleaning cylinder 301 is suspended when contacting the ground.

[0043] The cleaning device further includes a scraping member 5. The scraping member 5 is arranged to be installed on the device main body 1 and extend into the cylinder cavity 101 in a convex structure, mainly extending and protruding in the radial direction of the first cleaning cylinder 201 or the second cleaning cylinder 301, and the scraping member 5 is arranged to be movable in the protruding direction of the convex structure. By the movable structure of the scraping member 5, it can better and independently adapt to the first cleaning cylinder 201 and the second cleaning cylinder 301 for scraping dirt, achieving a better effect of scraping sewage and dirt from the first cleaning cylinder 201 and the second cleaning cylinder 301.

[0044] The cleaning device further includes a cover member 4. The cover member 4 is arranged to be detachably installed on the device main body 1, and at least a part of the cover member 4 is located above the scraping member 5. When the user installs or disassembles the cover member 4 in place, a cover cavity can be provided on the device main body 1, and the cover member 4 is installed in the cover cavity. The scraping member 5 can be installed in the cover cavity to extend and protrude in the radial direction of the first cleaning cylinder 201 or the second cleaning cylinder 301. The scraping member 5 has a length value in the axial direction of the first cleaning cylinder 201 or the second cleaning cylinder 301, and the convex structure constitutes the height value of the scraping member 5. When the first cleaning cylinder 201 and the second cleaning cylinder 301 are replaced with each other, both can be contacted by the scraping member 5 for scraping dirt. Only by setting a single scraping member 5 can the first cleaning cylinder 201 and the second cleaning cylinder 301 be independently scraped to remove sewage and dirt. The overall structure is simple and the cost is low. At the same time, it can better scrape and separate the sewage and dirt on the first cleaning cylinder 201 and the second cleaning cylinder 301.

[0045] Among them, a main body member 202 is provided on the first cleaning assembly 2. The main body member 202 is mounted on the equipment main body 1. The main body member 202 has a structure of non-rotating rolling motion. The first cleaning cylinder 201 is arranged to have a structure of rotating and rolling relative to the main body member 202. And a cushion part 2021 is provided on the main body member 202. The cushion part 2021 has a certain height in the up and down direction and has a moving length in the axial direction of the first cleaning cylinder 201 or the second cleaning cylinder 301. When the first cleaning assembly 2 is installed in place, the cushion part 2021 is located above the scraping member 5 and is in contact with the scraping member 5. At this time, the upper end face of the scraping member 5 is in contact with the lower end face of the cushion part 2021. When the cover member 4 is installed, the cover member 4 forms a pressing structure in contact with the cushion part 2021, so that the cover member 4 applies pressure to the scraping member 5 through the cushion part 2021 for pressing, causing the scraping member 5 to move in the convex direction, achieving the effect of moving the scraping member 5.

[0046] Among them, for the moving structure part of the scraping member 5, when the scraping member 5 does not contact the cushion part 2021, the scraping member 5 is in the initial position. When the scraping member 5 contacts the cushion part 2021, the scraping member 5 will be pressed and move to the moved position after moving in place. At this time, when the scraping member 5 contacts the cushion part 2021, the length value L1 of the scraping member 5 extending out in the cylinder cavity 101 is configured to scrape off the sewage on the first cleaning cylinder 201. When the scraping member 5 does not contact the cushion part 2021, the length value L2 of the scraping member 5 extending out in the cylinder cavity 101 is configured to scrape off the dirt on the second cleaning cylinder 301. It is set that L1 is greater than L2, that is, when the scraping member 5 is in the moved position along the convex direction, the extending length value L1 of the scraping member 5 in the cylinder cavity 101 is relatively large, while when the scraping member 5 is in the initial position, the extending length value L2 of the scraping member 5 in the cylinder cavity 101 is relatively small. This enables the scraping member 5 to better adapt to the first cleaning cylinder 201 and the second cleaning cylinder 301 respectively to scrape off sewage and dirt, can scrape off the sewage at a deeper position on the first cleaning cylinder 201 for separation, can scrape and separate the dirt adhered to the outer surface of the second cleaning cylinder 301, and makes the rotating and rolling motion of the second cleaning cylinder 301 more stable, and is not prone to problems such as jamming or bouncing during the rolling motion.

[0047] In this solution, the cover member 4 is configured to be detachably mounted on the device main body 1. The user can mount or dismount the cover member 4. For example, after the first cleaning assembly 2 is mounted in place, the user can then mount the cover member 4 in place. When it is necessary to replace the first cleaning assembly 2 with the second cleaning assembly 3, the cover member 4 can be dismounted at this time, and the first cleaning assembly 2 can be dismounted. Then, the second cleaning assembly 3 is mounted into the cylinder cavity 101 and the cover member 4 is mounted on the device main body 1, thus realizing the replacement of the first cleaning assembly 2 and the second cleaning assembly 3. Only one cover member 4 is needed to realize the crimping and fixing of the first cleaning assembly 2 and the crimping and fixing of the second cleaning assembly 3.

[0048] Among them, for the mounting structure part of the cover member 4, a structure for snap-fitting or plug-fitting can be formed on the device main body 1 to facilitate the disassembly or installation of the cover member 4.

[0049] Among them, when the cover member 4 is mounted in place and the first cleaning assembly 2 is mounted in place, the cover member 4 forms a crimping and limiting structure for a part of the first cleaning assembly 2, realizing the crimping and limiting fixation of the first cleaning assembly 2 in the cylinder cavity 101. At this time, the first cleaning cylinder 201 can perform rotational rolling motion to achieve the cleaning effect on the ground.

[0050] Among them, when the cover member 4 is mounted in place and the second cleaning assembly 3 is mounted in place, the cover member 4 forms a crimping and limiting structure for a part of the second cleaning assembly 3, realizing the crimping and limiting fixation of the second cleaning assembly 3 in the cylinder cavity 101. At this time, the second cleaning cylinder 301 can perform rotational rolling motion to achieve the cleaning effect on the ground.

[0051] In this solution, the scraping member 5 can be formed into a protruding structure when in the initial position, and the sewage and dirt on the second cleaning cylinder 301 can be scraped off through the protruding structure. At the same time, the scraping member 5 can also move along the protruding direction. After moving into place, the sewage and dirt on the first cleaning cylinder 201 can be scraped off through the protruding structure. The structure of the scraping member 5 in the two positions can better adapt to the first cleaning cylinder 201 and the second cleaning cylinder 301 respectively to scrape off sewage and dirt. Specifically, when the first cleaning assembly 2 and the cover member 4 are installed in place, the cover member 4 forms a pressing structure in contact with the cushion portion 2021, and the cushion portion 2021 forms a pressing structure in contact with the upper end surface of the scraping member 5, so that the scraping member 5 moves along the protruding direction. When the scraping member 5 moves into place, the scraping member 5 constitutes an interference structure with respect to the first cleaning cylinder 201 to scrape off sewage. During this process, the scraping member 5 moves along the protruding direction from the initial position, so that the length of the protruding structure elongates. The scraping member 5 after the elongation of the protruding structure forms a deep interference structure with respect to the first cleaning cylinder 201 to scrape off sewage and dirt. The longer length of the protruding structure can better extend into the inner side of the outer surface of the first cleaning cylinder 201 to form an interference structure with a deeper interference depth, thereby achieving a better effect of scraping off sewage from the first cleaning cylinder 201. Specifically, when the second cleaning assembly 3 and the cover member 4 are installed in place, the cover member 4 forms a pressing structure in contact with the upper end surface of the scraping member 5, so that the scraping member 5 constitutes a contact pressing structure with respect to the outer surface of the second cleaning cylinder 301 to scrape off dirt. When the first cleaning assembly 2 is replaced with the second cleaning assembly 3, at this time, the cover member 4 can form a direct contact pressing structure with respect to the scraping member 5. At this time, the scraping member 5 is in the initial position. When the scraping member 5 is in the initial position, it can form a relatively short protruding structure in the cylinder cavity 101. The relatively short length of the protruding structure can better contact and press against the outer surface of the second cleaning cylinder 301 to form a relatively contact scraping structure, thereby achieving a better effect of scraping off sewage from the second cleaning cylinder 301, and at the same time, the stability of the rotational rolling movement of the second cleaning cylinder 301 is better.

[0052] In this solution, for the movable structural part of the scraping member 5, the scraping member 5 is arranged to be mounted on the device main body 1 through an elastic member 6. When the scraping member 5 forms an interference structure with the first cleaning cylinder 201, the elastic member 6 is in a compressed structure. At this time, mainly the cover member 4 forms a crimping on the cushion part 2021, and the cushion part 2021 forms a crimping on the scraping member 5 to make the scraping member 5 move. The movement of the scraping member 5 realizes the crimping effect on the elastic member 6, making the elastic member 6 in a compressed structure. When the scraping member 5 forms a contact pressure structure with the second cleaning cylinder 301, the elastic member 6 is in an uncompressed structure. That is, when the user removes the cover member 4 to replace the first cleaning cylinder 201, at this time, when the cover member 4 is removed, the pressing force of the cover member 4 on the cushion part 2021 disappears. Under the compression elastic force of the elastic member 6, the scraping member 5 is pushed to move and reset to the initial position. The movement of the scraping member 5 makes the cushion part 2021 move upward and finally realizes the uncompressed structure of the elastic member 6. At this time, the user can remove the first cleaning cylinder 201 and replace it with the second cleaning cylinder 301, and then install the cover member 4 in place. At this time, the cover member 4 forms a crimping structure on a part of the second cleaning assembly 3 and forms a direct contact pressure structure on the scraping member 5. Since there is no cushion part 2021 on the second cleaning assembly 3, the elastic member 6 is in an uncompressed structure at this time. The above process realizes the movement process of the scraping member 5.

[0053] Among them, the elastic member 6 is a telescopic spring, and the number of the elastic members 6 can be set to be multiple. The multiple elastic members 6 are spaced along the length direction of the scraping member 5 or along the rotation axis of the first cleaning cylinder 201 or the second cleaning cylinder 301 to stably drive the scraping member 5 to move and return to the initial position.

[0054] In this solution, for the structural part where the first cleaning cylinder 201 and the second cleaning cylinder 301 rotate and roll, it is set that when the first cleaning cylinder 201 is installed in place, it is configured to be able to rotate and roll around the axis N in the cylinder cavity 101, and when the second cleaning cylinder 301 is installed in place, it is also configured to be able to rotate and roll around the axis N in the cylinder cavity 101. It is set that the moving direction of the scraping member 5 is not parallel to the axis N, so as to realize that both the first cleaning cylinder 201 and the second cleaning cylinder 301 can better contact the ground for cleaning during the process of mutual replacement, and at the same time, the scraping member 5 can better contact the first cleaning cylinder 201 or the second cleaning cylinder 301 to scrape off sewage and dirt.

[0055] Optionally, the moving direction of the scraping member 5 is set to be perpendicular to the axis N.

[0056] In order to further improve the effect of the scraping member 5 in scraping sewage and dirt from the first cleaning cylinder 201 and the second cleaning cylinder 301, in this solution, the outer diameter value of the first cleaning cylinder 201 is set to be greater than the outer diameter value of the second cleaning cylinder 301, and L is set to be less than or equal to 2 mm, and the difference between L1 and L2 is set to be greater than or equal to 3 mm and less than or equal to 6 mm. By limiting the difference in the outer diameter values between the first cleaning cylinder 201 and the second cleaning cylinder 301, and combining the structure in which the scraping member 5 can move and the extension length value of the scraping member 5 in the cylinder cavity 101, the scraping member 5 can better scrape sewage and dirt from the first cleaning cylinder 201 and the second cleaning cylinder 301 respectively.

[0057] In this solution, the structure in which the scraping member 5 can move realizes different scraping effects when the scraping member 5 scrapes sewage and dirt from the first cleaning cylinder 201 and the second cleaning cylinder 301 respectively. Among them, the maximum interference depth of the interference structure formed by the scraping member 5 and the first cleaning cylinder 201 is set to be greater than the maximum contact pressure depth of the contact pressure structure formed by the scraping member 5 and the second cleaning cylinder 301. That is, under the structure in which the scraping member 5 can move, when the scraping member 5 forms an interference structure with the first cleaning cylinder 201, a relatively large interference depth can be formed at this time, thereby realizing the effect of deeply interfering and scraping dirt and sewage from the first cleaning cylinder 201, and the sewage at a deeper position on the first cleaning cylinder 201 can be scraped in time, so that the first cleaning cylinder 201 can better maintain a clean state to clean the ground. When the scraping member 5 forms a contact pressure structure with the second cleaning cylinder 301, a relatively small contact pressure depth can be formed at this time, thereby realizing that the scraping member 5 can better form a contact scraping effect relative to the second cleaning cylinder 301 when contacting the outer surface of the second cleaning cylinder 301. As the second cleaning cylinder 301 continues to rotate and roll, a relative contact scraping effect will be formed between the scraping member 5 and the second cleaning cylinder 301, realizing that the scraping member 5 can better scrape the sewage and dirt on the outer surface of the second cleaning cylinder 301. At the same time, the second cleaning cylinder 301 can better deform and restore its shape, and the rotation and rolling motion state is more stable.

[0058] In order to further improve the stability of the movement of the scraping member 5 and better scrape sewage and dirt from the first cleaning cylinder 201 or the second cleaning cylinder 301, in this solution, the convex structure of the scraping member 5 is set to be a vertically distributed structure so that the scraping member 5 is configured to be a structure that can move in the vertical direction. The structure that moves in the vertical direction realizes better stability of the movement of the scraping member 5. At the same time, during the process of the scraping member 5 scraping sewage and dirt, the sewage and dirt adhering to the scraping member 5 are more likely to fall off downward, making the scraping member 5 easy to maintain a clean state and effectively preventing the problem of jamming when the scraping member 5 moves.

[0059] Alternatively, in order to further improve the stability of the scraping member 5 during movement and better scrape sewage and dirt from the first cleaning cylinder 201 or the second cleaning cylinder 301, in this solution, the convex structure of the scraping member 5 is set to face the center position of the cross-section of the first cleaning cylinder 201 or the second cleaning cylinder 301 in the radial direction and is inclined to protrude gradually downward, so that the scraping member 5 is configured to be movable in the inclined direction. The downward inclined structure makes the movement of the scraping member 5 more stable. At the same time, during the process of the scraping member 5 scraping sewage and dirt, the sewage and dirt adhering to the scraping member 5 are more likely to fall off downward, making it easier for the scraping member 5 to remain in a clean state and effectively preventing the problem of jamming when the scraping member 5 moves.

[0060] In this solution, in order to further improve the effect of the scraping member 5 scraping sewage and dirt from the first cleaning cylinder 201 or the second cleaning cylinder 301, the thickness value formed by the scraping member 5 in the rotational rolling direction is set to gradually decrease along the protruding direction. The structure with the gradually decreasing thickness value enables the scraping member 5 to better extend into the inner side of the outer surface of the first cleaning cylinder 201 to form an interference structure, which can better separate the sewage and dirt at a deeper position in the first cleaning cylinder 201. At the same time, it can also form a better guiding effect to separate the sewage and dirt from the scraping member 5, making it difficult for the sewage and dirt to adhere to the outer surface of the scraping member 5. And the end position of the scraping member 5 is set to be an arc structure in the rotational rolling direction. The arc structure makes it difficult for the scraping member 5 to damage the first cleaning cylinder 201 or the second cleaning cylinder 301 when it forms an interference structure with the first cleaning cylinder 201. When the scraping member 5 scrapes dirt from the second cleaning cylinder 301, it can achieve a better relative contact and scraping effect at the end position of the scraping member 5 on the outer surface of the second cleaning cylinder 301, thus improving the effect of scraping dirt and sewage from the second cleaning cylinder 301.

[0061] Preferably, the end position of the scraping member 5 is set to a U-shaped structure.

[0062] In this solution, for the specific structural part of the first cleaning cylinder 201, the first cleaning cylinder 201 is mainly set to be a flexible structure so that when it contacts the ground, it is configured to contact and fit the ground and absorb sewage. When a part of the first cleaning cylinder 201 contacts the ground, it will deform to contact and fit the ground, achieving the cleaning effect on the ground and absorbing the sewage on the ground.

[0063] In this solution, for the specific structure part of the second cleaning cylinder 301, the second cleaning cylinder 301 is mainly set to be a flexible and deformable structure so that it will deform when contacting the ground to form a concave part, and the concave part is configured to contact and scrape the ground to drive the dirt to be transferred along the rotation and rolling direction. When a part of the second cleaning cylinder 301 contacts the ground, it will be under pressure and deform. A part of the second cleaning cylinder 301 deforms and sinks inward to form a concave part. The two edge positions of the concave part in the rotation and rolling direction contact the ground to form a scraping and cleaning effect. The dirt and sewage enter the concave part during the scraping process, and are driven by the concave part to be transferred along the rotation and rolling movement direction, and finally the collection and treatment of the dirt and sewage are realized.

[0064] It can be understood that a part of the second cleaning cylinder 301 will form a concave part when contacting the ground. When the part contacting the ground leaves the ground with the rotation and rolling movement, it will deform to restore its shape and finally return to the arc structure.

[0065] Among them, the first cleaning cylinder 201 is mainly composed of a hair planting layer or a sponge layer, so that the first cleaning cylinder 201 has a flexible structure and a water-absorbing structure, and can absorb the sewage on the ground when cleaning the ground.

[0066] Among them, the second cleaning cylinder 301 is mainly made of a glue material, such as silica gel, silicone rubber, etc., so that the second cleaning cylinder 301 has a flexible and deformable structure and a hydrophobic structure, that is, a structure that does not absorb sewage, and can accommodate and drive the sewage and dirt on the ground for transfer when cleaning the ground.

[0067] In this solution, a driving structure is provided on the equipment main body 1. The driving structure includes a motor and a transmission structure. The transmission structure can be a gear transmission structure or a belt pulley transmission structure, so that the motor provides a driving force to rotate and roll the first cleaning cylinder 201 or the second cleaning cylinder 301 to achieve the cleaning effect on the ground.

[0068] In this solution, for the movable structural part of the scraping member 5, a channel portion 102 is provided on the device main body 1. At least a part of the scraping member 5 is located within the channel portion 102 for movement. And when the scraping member 5 moves, a structure is set such that the two side surfaces of the scraping member 5 in the rotational rolling direction do not contact the channel wall of the channel portion 102 simultaneously. Specifically, a part of the scraping member 5 extends into and passes through the channel portion 102 in the protruding direction to enter the cylinder cavity 101. When the scraping member 5 moves, a structure for moving within the channel portion 102 is formed. To improve the stability and reliability of the movement of the scraping member 5 and prevent the scraping member 5 from getting stuck during movement, a structure is set such that the two side surfaces of the scraping member 5 in the rotational rolling direction do not contact the channel wall of the channel portion 102 simultaneously, so as to reduce the contact area between the scraping member 5 and the channel portion 102, thereby reducing the frictional force and enabling one side surface of the scraping member 5 to contact a part of the channel wall of the channel portion 102 to form a guiding movement effect. At this time, the other side surface of the scraping member 5 does not contact the channel wall of the channel portion 102, thus enabling the scraping member 5 to move more smoothly within the channel portion 102.

[0069] It can be understood that during the process of the scraping member 5 scraping sewage and dirt from the first cleaning cylinder 201 or the second cleaning cylinder 301, part of the sewage or dirt easily flows along the outer surface of the scraping member 5 into the channel portion 102, which easily causes the problem of the scraping member 5 getting stuck. By setting a structure such that the two side surfaces of the scraping member 5 in the rotational rolling direction do not contact the channel wall of the channel portion 102 simultaneously, a non-contact gap structure is formed between one side surface of the scraping member 5 and the channel wall of the channel portion 102. This can effectively improve the smoothness and stability of the movement of the scraping member 5 and prevent the problem of the scraping member 5 getting stuck during movement.

[0070] The cleaning device of this solution can be a floor washer, a floor scrubber, etc., or a cleaning robot.

[0071] For the parts not described in this solution, the prior art can be adopted or borrowed to achieve.

[0072] Working principle: For the cleaning device of this solution, a first cleaning component 2, a second cleaning component 3 and a scraping member 5 are provided. The first cleaning component 2 and the second cleaning component 3 can be replaced with each other to independently achieve the cleaning effect on the ground. The scraping member 5 is configured as a movable structure to independently scrape sewage and dirt from the first cleaning cylinder 201 and the second cleaning cylinder 301 respectively. Through the setting of the movable structure of the scraping member 5, a single scraping member 5 can preferably achieve the effect of scraping sewage and dirt from the first cleaning cylinder 201 and the second cleaning cylinder 301 respectively, making the overall structure simple and the cost low. At the same time, by providing a cover member 4 and a cushion portion 2021 on the first cleaning component 2, the cover member 4 contacts and presses the cushion portion 2021, and the cushion portion 2021 contacts and presses the scraping member 5, thereby providing power for the movement of the scraping member 5 and enabling the length of the protruding structure formed by the scraping member 5 extending in the cylinder cavity 101 to be longer. At this time, the scraping member 5 can better form an interference structure with the first cleaning cylinder 201, thereby improving the effect of scraping sewage from the first cleaning cylinder 201. When the second cleaning cylinder 301 is installed in place, the cover member 4 directly forms a contact and pressing structure with the scraping member 5, making the length of the protruding structure formed by the scraping member 5 extending in the cylinder cavity 101 relatively shorter. At this time, the scraping member 5 can preferably contact and press the outer surface of the second cleaning cylinder 301 to scrape dirt. At the same time, because the depth of the contact and pressing is relatively small, the rotational rolling movement of the second cleaning cylinder 301 can be more stable, and problems such as jamming or bouncing during the rolling movement are not likely to occur. The structures of the first cleaning component 2, the second cleaning component 3, and the scraping member 5 as a whole improve the cleaning effect on the ground, reduce secondary pollution to the ground, and enhance the user experience effect.

[0073] Those of ordinary skill in the art can understand that the above embodiments are specific embodiments for implementing the present utility model. In actual applications, various changes can be made in form and details without departing from the spirit and scope of the present utility model, and all are within the protection scope of the present utility model.
