It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.

[0027] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0028] like Figure 1As shown, the embodiment of the utility model provides a cleaning device, including a base 1, a cleaning member 2 and a combing structure 3. The cleaning member 2 is rotatably connected to the base 1, and the cleaning member 2 has a cleaning portion 21, and the cleaning member 2 is used to rotate relative to the base 1 so that the cleaning portion 21 rolls and mops the surface to be cleaned. The surface to be cleaned is usually the ground to be cleaned, but can also be other planes to be cleaned such as walls and ceilings. The combing structure 3 is connected to the base 1, and the combing structure 3 abuts against the cleaning portion 21.

[0029] Specifically, Figure 1 As shown, the cleaning member 2 is usually rotatably connected to the base 1 via a roller 22. Optionally, the cleaning member 2 can be rotatably connected to the base 1 via one or more rollers 22. When the cleaning member 2 is rotatably connected to the base 1 via only one roller 22, the cleaning member 2 is usually a cylindrical rotating structure that can rotate relative to the base 1 and achieve a cleaning effect through the cleaning portion 21. When the cleaning member 2 is rotatably connected to the base 1 via two or more rollers 22, as shown in FIG. Figure 1 As shown, taking two rollers 22 as an example, there is a certain interval between two adjacent rollers 22, and a member with cleaning performance (such as a cleaning cloth or cleaning cotton) is wound on the two rollers 22 to form a cleaning part 21. In this way, the cleaning member 2 can form a crawler structure, with a straight portion between adjacent rollers 22, and the straight portion is the portion where the cleaning member 21 mainly contacts the surface to be cleaned, so as to clean the surface to be cleaned. The contact area between the straight portion and the surface to be cleaned is large. At the same speed, the cleaning member 21 contacts and rubs the same position of the surface to be cleaned for a longer time, thereby greatly improving the cleaning efficiency. Optionally, the cleaning member 2 can be driven by a motor to rotate, and the motor can also be operated under the control of a logic control circuit to realize automation and intelligence of the operation of the cleaning member 2. Of course, it can be understood that in some designs, the cleaning member 2 can also be manually controlled, for example, the cleaning member 2 can be rotated relative to the base 1 by the user moving the base 1.

[0030] Specifically, Figure 1As shown, the cleaning portion 21 is the portion of the cleaning member 2 that is in direct contact with the surface to be cleaned, and can be optionally configured as an annular cleaning belt, which is usually wrapped around the outer side of the roller 22 in the direction of rotation of the cleaning member 2, and can rotate synchronously with the roller 22. When rotating, the cleaning portion 21 and the surface to be cleaned rub against each other, thereby cleaning the surface to be cleaned. It should be noted that the cleaning portion 21 is cleaned by rolling and mopping, specifically, the dirt on the surface to be cleaned is wiped off by squeezing and rubbing. Therefore, the cleaning portion 21 is usually a soft structure that can be deformed and can absorb or squeeze out water, and the outer side of the cleaning portion 21 usually has fluff. Optionally, the cleaning portion 21 can be made of a soft and absorbent material such as flannel. In some designs, a ready-made towel, rag, etc. can also be used to wrap around the outer side of the roller 22 to serve as the cleaning portion 21, and it is only necessary to enable it to roll and mop the surface to be cleaned.

[0031] Specifically, since the cleaning part 21 usually absorbs a certain amount of water when performing rolling and mopping cleaning, and is squeezed and rubbed against the surface to be cleaned many times, this can easily cause the fluff of the cleaning part 21 to be squeezed together and collapse. When the cleaning part 21 collapses, the actual use thickness of the cleaning part 21 will become thinner, resulting in a reduction in the amount of deformation of the cleaning part 21 caused by squeezing when it contacts the surface to be cleaned, that is, the contact between the cleaning part 21 and the surface to be cleaned is not sufficient, which has a significant adverse effect on the effect of rolling and mopping cleaning. Therefore, in order to at least alleviate this adverse effect and improve the effect of rolling and mopping cleaning of the cleaning part 21, the cleaning device provided in the embodiment of the utility model is designed with a combing structure 3, which can be a cantilever structure with one end connected to the base 1 and the other end extending toward the cleaning member 2. Optionally, the combing structure 3 can be formed by a single component, one end of which is connected to the base 1, and the other end of which extends toward the cleaning member 2 and abuts against the cleaning portion 21; the combing structure 3 can also be assembled from a plurality of components, and the components can be arranged to be detachable so that the components on the combing structure 3 can be removed individually for replacement or cleaning.

[0032] Specifically, the combing structure 3 is in contact with the cleaning portion 21, which means that the combing structure 3 is in contact with the cleaning portion 21 in a direction opposite to the rotation direction of the cleaning member 2 (i.e., direction A shown in the figure), and the combing structure 3 can form a certain squeezing effect on the cleaning portion 21, and when the cleaning portion 21 rotates through the combing structure 3, the combing structure 3 can rub against the cleaning portion 21, so that the fluff on the cleaning portion 21 can expand outward under the squeezing and friction of the combing structure 3, so that the fluff on the outside of the cleaning portion 21 is more fluffy than before passing through the combing structure 3, and fills between the cleaning member 2 and the surface to be cleaned. When the cleaning portion 21 contacts the surface to be cleaned, it can contact the surface to be cleaned more fully, which is beneficial to improving the cleaning effect of the cleaning portion 21.

[0033] The cleaning device provided by the embodiment of the utility model includes a base 1, a cleaning member 2 and a combing structure 3, wherein the cleaning member 2 has a cleaning portion 21, and the combing structure 3 abuts against the cleaning portion 21 to at least comb the cleaning portion 21. The utility model can comb the cleaning portion 21 while performing rolling and mopping cleaning by setting the combing structure 3 to abut against the cleaning portion 21, so that the fluff on the cleaning portion 21 expands outward under the squeezing and friction of the combing structure 3, so as to ensure that the cleaning portion 21 is in full contact with the surface to be cleaned, thereby improving the cleaning effect of the cleaning device. Through the above design, when performing continuous rolling and mopping cleaning operations, the cleaning portion 21 can pass through the combing structure 3 and be combed at least once for each rotation, so that the cleaning portion 21 always maintains full contact with the surface to be cleaned, maintains a good cleaning effect, and maintains a stable continuous cleaning effect.

[0034] In some embodiments, Figure 1 As shown, the combing structure 3 includes a combing plate 31, one end of the combing plate 31 is in contact with the cleaning portion 21, and the other end of the combing plate 31 is connected to the base 1. Figure 1 In the direction of the paper surface), the length of the combing plate 31 is equal to or close to the length of the cleaning member 2. Specifically, the combing structure 3 is in contact with the cleaning portion 21 through the combing plate 31. The combing structure 3 may be composed of only the combing plate 31, or may include other components. For example, the combing structure 3 may include a fixing member, which is connected to the base 1 and the combing plate 31, so that the combing plate 31 is indirectly connected to the base 1 through the fixing member.

[0035] Through the above design, it is possible to ensure that the length of the combing plate 31 better covers the length of the cleaning member 2, so that the combing plate 31 can comprehensively comb the cleaning portion 21 of the cleaning member 2, and the combing effect is better. It can be understood that in some embodiments, the length of the combing plate 31 can also be less than the length of the cleaning member 2. For example, when the length of the cleaning portion 21 only covers a portion of the length of the cleaning member 2, the length of the combing plate 31 only needs to cover at least the length of the cleaning portion 21.

[0036] In some embodiments, Figure 1 As shown, the combing plate 31 is provided with a bending portion 311, and the bending portion 311 is bent in a direction opposite to the rotation direction of the cleaning member 2 (i.e., direction A in the figure), so that the end of the combing plate 31 abutting against the cleaning member 21 abuts against the direction opposite to the rotation direction of the cleaning member 2. Specifically, when the combing plate 31 is provided on both sides of the front and rear of the cleaning member 2 along the travel direction (i.e., Figure 1The bent portion 311 can be understood as being upwardly tilted relative to the surface to be cleaned, so that a certain angle is formed between the combing plate 31 and the cleaning portion 21. Optionally, the bent portion 311 can be integrally formed with the body of the combing plate 31, or can be an independent component and connected to the body of the combing plate 31.

[0037] Through the above design, the combing plate 31 abuts against the cleaning portion 21 in the direction opposite to the rotation direction of the cleaning member 2, and the contact and compression between the combing plate 31 and the cleaning portion 21 are more sufficient, further improving the combing effect. It is understandable that the above-mentioned bending portion 311 may not be provided on the combing plate 31. For example, the combing plate 31 may be tilted upward relative to the surface to be cleaned, or may be arranged parallel to the surface to be cleaned, which also has the effect of combing the cleaning portion 21.

[0038] In some embodiments, Figure 2 As shown, the combing structure 3 also includes comb teeth 32, which are arranged at one end of the combing plate 31 abutting against the cleaning part 21, and the comb teeth 32 are used to at least partially insert into the cleaning part 21. Among them, a plurality of comb teeth 32 are arranged at intervals along the rotation axis of the cleaning member 2. Specifically, the comb teeth 32 are convex structures with relatively small widths, so that a plurality of comb teeth 32 can be arranged at intervals along the rotation axis of the cleaning member 2, and a plurality of comb teeth 32 arranged at intervals form a zigzag structure, and there are also gaps between the fluff on the outside of the cleaning part 21, so that the comb teeth 32 can be inserted into the gaps between the fluff of the cleaning part 21, and at the same time, as the cleaning part 21 rotates, the comb teeth 32 and the fluff of the cleaning part 21 will collide several times, thereby achieving the purpose of combing the cleaning part 21. Through the above design, the comb teeth 32 are inserted into the cleaning part 21 for combing, which can further improve the combing effect. It can be understood that the combing structure 3 may not include the comb teeth 32, for example, the combing can be performed only by the abutment of the combing plate 31 and the cleaning part 21.

[0039] In some embodiments, Figure 1 and Figure 2 As shown, the combing structure 3 includes an elastic member 33, one end of the elastic member 33 is connected to the combing plate 31, and the other end of the elastic member 33 is connected to the base 1. The elastic member 33 is used to apply elastic force to the combing plate 31, so that the combing plate 31 presses the cleaning part 21 in the direction opposite to the rotation direction of the cleaning member 2. Specifically, when the combing plate 31 combs the cleaning part 21, it will be subjected to the reaction force of the cleaning part 21. The reaction force can be transmitted to the elastic member 33 through the combing plate 31, so that the elastic member 33 is elastically deformed to generate elastic force. The elastic force acts on the combing plate 31, so that the combing plate 31 can always keep pressing the cleaning part 21, thereby maintaining a good combing effect. Optionally, the elastic member 33 can be a spring, a spring sheet, or an elastic pad.

[0040] In some embodiments, Figure 1 and Figure 2 As shown, a receiving groove 11 is provided at the position where the base 1 is connected to the elastic member 33, and the elastic member 33 is at least partially received in the receiving groove 11. Among them, one end of the elastic member 33 received in the receiving groove 11 is connected to the base 1, and the other end of the elastic member 33 opposite to the carding plate 31. Specifically, the end of the elastic member 33 connected to the base 1 can be connected to the bottom of the receiving groove 11, and the "other end opposite to the elastic member 33" refers to the end of the elastic member 33 away from the bottom of the receiving groove 11. Optionally, the end of the elastic member 33 away from the bottom of the receiving groove 11 can be located in the receiving groove 11, can be flush with the opening of the receiving groove 11, or can extend out of the opening of the receiving groove 11.

[0041] Through the above design, the space occupied by the elastic member 33 outside the base 1 can be saved, and the elastic member 33 is not exposed to the environment, which has a better aesthetic appearance. At the same time, the accommodating groove 11 also has a protective and guiding function for the elastic member 33, which can prevent the elastic member 33 from colliding with external debris or being contaminated, and guide the elastic member 33 to apply elastic force in the correct direction.

[0042] In some embodiments, Figure 1 and Figure 2 As shown, the combing structure 3 further includes a rotating shaft 34, which is connected to the combing plate 31 and is located between one end of the combing plate 31 abutting against the cleaning part 21 and one end of the elastic member 33 connected to the combing plate 31. The rotating shaft 34 is rotatably connected to the base 1 so that the combing plate 31 rotates relative to the base 1. Optionally, the rotating shaft 34 can be parallel to the rotation axis of the cleaning member 2, so that the force at each part of the combing plate 31 abutting against the cleaning part 21 can be uniform; the rotating shaft 34 can also be set at a certain angle to the rotation axis of the cleaning member 2, and such a design can also enable the combing plate 31 to rotate relative to the base 1.

[0043] Through the above design, the relative position of the combing plate 31 and the elastic member 33 is further optimized, that is, the end of the combing plate 31 abutting against the cleaning part 21 and the end of the elastic member 33 connected to the combing plate 31 are respectively located on both sides of the rotating shaft 34, so that the combing plate 31 forms a lever structure with the rotating shaft 34 as the fulcrum. Compared with the design without the rotating shaft 34, the above design can reduce the bending deformation of the combing plate 31 when it is stressed, and improve the durability of the combing plate 31. In some designs, the rotating shaft 34 can also be arranged near the end of the combing plate 31 abutting against the cleaning part 21, so that the combing plate forms a labor-saving lever structure, so that the elastic member 33 applies a small elastic force to make the end of the combing plate 31 abutting against the cleaning part 21 generate a large extrusion force on the cleaning part 21, so that the combing plate 31 maintains a good extrusion on the cleaning part 21, and further improves the combing effect.

[0044] In some embodiments, Figure 1 and Figure 2 As shown, the cleaning device further includes a scraper 4 and a collection box 5. The scraper 4 abuts against the cleaning portion 21 to scrape off dirt on the cleaning portion 21. The collection box 5 is connected to the scraper 4 and the base 1, and the collection box 5 is used to collect the dirt scraped off by the scraper 4. After the cleaning portion 21 rolls and mops the surface to be cleaned, it can pass through the scraper 4 and the combing structure 3 in sequence.

[0045] Specifically, the dirt includes sewage, dust, hair, etc. Since the cleaning portion 21 usually absorbs water to perform rolling and mopping cleaning to improve the cleaning effect, the dirt usually contains water. When the cleaning portion 21 rotates and passes through the scraper 4, the dirt and water adsorbed on the cleaning portion 21 are scraped off under the squeezing action of the scraper 4, so that the cleaning portion 21 is relatively clean, so as to facilitate subsequent cleaning work. At the same time, the dirt scraped off by the scraper 4 can flow along the surface of the scraper 4 into the collection box 5 connected thereto, so that the dirt is separated and collected for centralized treatment.

[0046] Specifically, when the cleaning device includes a scraper 4, the cleaning portion 21 will also pass through the scraper 4. The scraper 4 will squeeze out the moisture absorbed by the cleaning portion 21 while scraping off the dirt, which will also cause the cleaning portion 21 to collapse. The combing structure 3 designed in the present invention can comb the collapsed cleaning portion 21 to improve the problem that the cleaning portion 21 collapses after passing through the scraper 4 and affects the cleaning effect. It should be noted that the scraper 4, the combing structure 3 and the surface to be cleaned have a specific relative position, that is, the three are arranged along the rotation direction of the cleaning member 2, so that after the cleaning portion 21 rolls and mops the surface to be cleaned, it first passes through the scraper 4 to remove dirt, then passes through the combing structure 3 to be combed, and finally contacts the surface to be cleaned again for cleaning, and the cycle continues, instead of first passing through the scraper 4, then passing through the surface to be cleaned, and finally passing through the combing structure 3, nor first passing through the combing structure 3, then passing through the scraper 4, and finally passing through the surface to be cleaned. To achieve the above functions, please refer to Figure 1 In the design shown, optionally, the scraper 4 and the collection box 5 on the left side of the cleaning member 2 in the figure can also be set above or on the right side of the cleaning member 2. When the scraper 4 and the collection box 5 are set on the right side of the cleaning member 2, the combing structure 3 can also be set above the cleaning member 2, as long as the above relative position relationship is met. With such a design, the cleaning part 21 becomes cleaner after passing through the scraper 4, and can absorb more dirt in the next round of cleaning. Subsequently, the cleaning part 21 is combed by the combing structure 3, and its fluff becomes more fluffy and can fully contact with the surface to be cleaned, and the cleaning effect is significantly improved.

[0047] In the above embodiment, the scraper 4 is used to scrape off the dirt on the cleaning part 21, and the dirt is collected by the collecting box 5, which is beneficial for the cleaning part 21 to perform continuous cleaning work and facilitates centralized treatment of the dirt.

[0048] It is understandable that in some of the embodiments described above, the “combing structure 3 is connected to the base 1” may be directly or indirectly connected to the base 1, for example, Figure 1 As shown, the combing structure 3 can be connected to the collection box 5, that is, indirectly connected to the base 1 through the collection box 5. In addition, the aforementioned "the base 1 is provided with a receiving groove 11 at the position where the elastic member 33 is connected", and the receiving groove 11 can also be provided on the collection box 5. In other words, the collection box 5 can be regarded as a part of the base 1.

[0049] In some embodiments, Figure 1 and Figure 2 As shown, a through hole 51 is provided at the connection between the collection box 5 and the scraper 4, and the through hole 51 is used for the dirt scraped by the scraper 4 to enter the collection box 5. Specifically, a plurality of through holes 51 can be provided at intervals, and the shape of the through hole 51 can be a circular, elliptical, long strip or other shape that is easy to process. Through the above design, small-sized dirt and sewage scraped by the scraper 4 can enter the collection box 5 through the through hole 51, while larger-sized dirt can be blocked at the position of the through hole 51, which has a filtering effect and is convenient for the classification, collection and treatment of dirt. For example, small-sized dirt and sewage in the collection box 5 can be directly poured into the sewer, while larger-sized dirt can be poured into a trash can to prevent large-sized dirt from clogging the sewer.

[0050] In some embodiments, optionally, the end of the scraper 4 that abuts against the cleaning portion 21 may be higher than the end of the scraper 4 that is connected to the collection box 5. The "higher than" is relative to the ground, and the purpose is to allow the dirt scraped by the scraper 4 to flow from a high place to a low place under the action of gravity. This design has a diversion effect on the dirt on the scraper 4, and can speed up the speed of the dirt flowing into the collection box 5, reducing the time that the dirt accumulates and stays on the scraper 4, and improving the collection efficiency of the dirt. It is convenient for the collection of dirt. It can be understood that the scraper 4 can also be set horizontally, such as Figure 1 As shown, or it can be flexibly designed according to different usage scenarios.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
