Detailed ways

In order to make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be described clearly and completely below in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

The technical solutions disclosed in the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in Figures 1 to 11, the embodiment of the present invention discloses a cleaning device, which includes a housing 100, a dirty liquid containing mechanism 200, a driving mechanism 400 and a plurality of roller brushes.

Among them, as shown in FIG. 9, the housing 100 is an installation foundation for other components, which can be made of plastic or metal materials, and its size and specific shape can be flexibly selected according to the actual structure of other components in the cleaning device.

The number of roller brushes can be determined according to actual conditions, and the number can be two, three, four or more. A plurality of rolling brushes are all installed on the housing 100, and the plurality of rolling brushes may all have a cylindrical structure, and the size of each rolling brush may be the same or different from each other. As shown in FIG. 3, the roller brush includes a cleaning part 330 and a mounting part 340. The cleaning part 330 is surrounded by the outer periphery of the mounting part 340 and is mounted on the mounting part 340.

In the process of using the cleaning equipment, the cleaning part 330 can absorb liquids such as water, and complete the cleaning work on the cleaned surface through mutual contact and relative movement with the cleaned surface. The cleaning part 330 can be formed of fiber materials such as cotton, hemp, wool, etc., and the texture of the material forming the cleaning part 330 can be made relatively soft, and has a higher water absorption performance, which can further improve the cleaning part 330 to the surface to be cleaned. The cleaning effect.

The installation part 340 may have a cylindrical structure to provide an installation foundation for the cleaning part 330 and enable the entire roller brush to have rolling capability, so that by moving the position of the entire cleaning device, cleaning work can be performed on different areas of the surface to be cleaned. In addition, the cleaning part 330 may also have a cylindrical structure to be sleeved and mounted on the mounting part 340, and since the material forming the cleaning part 330 usually has a certain elasticity, it can be ensured that the cleaning part 330 can be more reliably secured. Installed on the mounting part 340. In order to ensure high connection reliability between the cleaning part 330 and the mounting part 340, optionally, the cleaning part 330 may be glued to the surface of the mounting part 340 by glue.

In order to ensure that the roller brush can rotate automatically to move the position of the entire cleaning device to clean different areas of the surface to be cleaned, the driving mechanism 400 can be connected with at least one mounting portion 340, so as to drive the roller brush to rotate under the action of the driving mechanism 400 , So that each mounting part 340 can rotate.

Optionally, the driving mechanism 400 can be connected with only one roller brush to drive the roller brush to rotate. In the case of one roller brush actively rotating, the other roller brushes can also act under the drive of the roller brush to ensure the entire cleaning. The equipment can move relative to the surface to be cleaned to complete the cleaning of different areas on the surface to be cleaned.

The driving mechanism 400 can be a motor, which can be directly connected to the mounting portion 340 to drive the mounting portion 340 to rotate, or the mounting portion 340 can be indirectly connected to the motor by means of a transmission mechanism such as a belt, etc., which can ensure that the motor The mounting part 340 can be driven to rotate stably to perform cleaning work.

Considering that before or during the operation of the cleaning equipment, it may be necessary to spray water on the cleaned surface to improve the cleaning effect. In order to prevent a large amount of water from remaining on the cleaned surface after wiping, as shown in Figures 3 and 5, the present invention The cleaning device disclosed in the embodiment is provided with a dirty liquid containing mechanism 200, and the cleaning part 330 of each roller brush is matched with the dirty liquid containing mechanism 200, so that the sewage and other liquid absorbed by the cleaning part 330 can be collected into the dirty liquid. In the liquid containing mechanism 200, the amount of sewage remaining on the cleaned surface after the wiping is completed is minimized.

The number of dirty liquid containing mechanisms 200 can be determined according to actual requirements. For example, each roller brush may be individually equipped with a dirty liquid containing mechanism 200, or multiple roller brushes may share the same dirty liquid containing mechanism 200. The dirty liquid containing mechanism 200 can squeeze out the sewage absorbed in the cleaning part 330 by squeezing and fitting with the rolling brush, and store it in its own chamber. When the cleaning work is completed or completely completed, the sewage and other liquids contained in the chamber 200 of the dirty liquid containment mechanism are poured out. In order to keep the cleaning equipment clean and prolong the service life of the equipment, the dirty liquid containment mechanism can be 200 and the rest of the cleaning equipment for deep cleaning.

As shown in FIG. 11, the dirty liquid containing mechanism 200 may include a liquid collecting part 210 and a top cover part 270. The top cover part 270 and the liquid collecting part 210 enclose a liquid collecting cavity 213, and the top cover part 270 has a liquid collecting port 271. Along the direction perpendicular to the circumferential direction of the roller brush, the liquid collection port 271 is located in the middle of the top cover part 270. During the use of the cleaning equipment, even if the cleaning equipment is tilted, it can prevent the dirty liquid from collecting liquid to a certain extent. Splashes out of the cavity 213. It should be noted that the middle part of the top cover part 270 is a concept opposite to the edge of the top cover part 270. It can also be said that the liquid collection port 271 is not provided on the edge of the top cover part 270 to prevent the cleaning equipment from being tilted. The dirty liquid in the liquid cavity 213 is easier to splash out from the liquid collecting port 271. In addition, the direction perpendicular to the circumferential direction of the roller brush may be the direction A in FIG. 11.

Specifically, the liquid collection part 210 and the top cover part 270 can be formed separately, and then the top cover part 270 can be detachably connected to the liquid collection part 210 by means of a structure such as a buckle, so that in the process of treating the dirty liquid, By removing the top cover portion 270, the cross-sectional area of the liquid collecting portion 210 communicating with the outside can be increased, so that the dirty liquid can be discharged to the outside of the liquid collecting cavity 213 more quickly.

Alternatively, as shown in FIG. 10, the top cover 270 can be movably mounted on the liquid collecting part 210 through hinges 218 and other components. By rotating the top cover 270, the communication cross-sectional area of the liquid collecting cavity 213 and the outside can also be increased. , To speed up the discharge speed of the dirty liquid; and, when the above-mentioned connection method is adopted, the top cover part 270 can be prevented from being lost, and the difficulty of disassembly and assembly between the top cover part 270 and the liquid collection part 210 can be reduced, and the user experience can be improved. In addition, as shown in FIG. 8, a push button 216 may be provided on the top cover part 270, and the pushing direction can be marked on the top cover part 270, so as to provide the user with an instruction and explanation function, which is convenient for the user to use. In detail, during the use of the cleaning device, if it is necessary to discharge the dirty liquid, the user can use the push button 216 to push the top cover part 270 to rotate relative to the liquid collecting part 210 in the direction indicated to enlarge the cross-sectional area of the liquid collecting chamber 213 communicating with the outside. , And then tilt the liquid collecting part 210 to pour out the dirty liquid. After the liquid collecting part 210 is cleaned, the top cover part 270 is rotated in the reverse direction by the push button 216, so that the top cover part 270 and the liquid collecting part 210 can be fixed as a whole.

Of course, in order to make the fixed connection relationship between the top cover part 270 and the liquid collection part 210 more stable, an elastic buckle can be provided on the top cover part 270 or the liquid collection part 210, so as to ensure that the top cover is in use during the cleaning device. The part 270 will not be automatically separated from the liquid collecting part 210 to prevent dirty liquid from splashing out of the liquid collecting cavity 213.

The liquid collection port 271 can be integrally formed with the molding of the top cover part 270. The whole top cover part 270 can have an approximately rectangular structure. After the liquid parts 210 are connected to each other to form the liquid collecting cavity 213, even if the dirty liquid containing mechanism 200 is inclined with the cleaning equipment, the distance between the liquid collecting port 271 and the supporting surface such as the cleaned surface is relatively large, so as to prevent the liquid collecting cavity as much as possible. The dirty liquid in 213 spilled out. Optionally, the number of the liquid collecting ports 271 may be one or more, and each liquid collecting port 271 cooperates with the rolling brush to collect liquid such as sewage squeezed from the rolling brush.

As shown in FIG. 11, the top cover part 270 may include a top wall 272, a blocking wall 273 and a liquid conducting wall 274, wherein the top wall 272 is disposed toward the bottom of the liquid collecting part 210, optionally, the top wall 272 and the liquid collecting part The bottoms of 210 are parallel to each other; the blocking wall 273 is connected to the edge of the top wall 272, and the blocking wall 273 extends in the direction close to the bottom of the liquid collecting part, the liquid guiding wall 274 is connected to the blocking wall 273, and the liquid guiding wall 274 faces away from the collection. The direction of the bottom of the liquid part 210 extends obliquely, which enables the liquid guiding wall 274 and the blocking wall 273 to form an inclined sink, and the inclined sink is set to sink relative to the top wall 272, so that the liquid guiding wall 274 is set during the working process of the cleaning device. It can provide a diversion effect for the dirty liquid squeezed out from the rolling brush. The blocking wall 273 can prevent the dirty liquid from continuing to flow. Under the joint action of the liquid guiding wall 274 and the blocking wall 273, the dirty liquid can be freely located on the liquid guiding wall 274 and the blocking wall. The liquid collecting port 271 at the connection of the wall 273 is collected into the liquid collecting cavity 213.

Optionally, the liquid collecting portion 210 may have a rectangular or approximately rectangular structure, which includes four side portions and a bottom portion. All the aforementioned four side portions may be connected to the top wall 272, and the top wall 272 has a gap, and the blocking wall 273 The liquid-conducting wall 274 can be arranged at the aforementioned notch, and the liquid-conducting wall 274 is connected to one side of the liquid collecting part 210 to ensure that the top cover part 270 and the liquid collecting part 210 can be connected to each other to form a liquid collecting cavity 213. Of course, the actual structures of the capping wall 272, the blocking wall 273, and the liquid conducting wall 274 can be determined according to specific conditions, and are not limited here. Specifically, the capping wall 272, the blocking wall 273, and the liquid conducting wall 274 can be formed in an integrated manner to improve the structural stability of the entire top cover portion 270.

Optionally, as shown in FIG. 11, the barrier wall 273 may extend in a vertical direction. Compared with the oblique arrangement of the barrier wall 273, the vertically extending barrier wall 273 can provide a better barrier effect for the dirty liquid, and also It can be ensured that there is a large space between the blocking wall 273 and the liquid conducting wall 274, so that when the flow of the dirty liquid is large, it can basically be ensured that the dirty liquid can flow from the liquid collecting port 271 into the liquid collecting cavity without any occurrence. Sputtering.

In order to prevent the liquid collecting port 271 from being blocked when the instantaneous flow of the dirty liquid is large, the gas remaining in the liquid collecting cavity 213 cannot be discharged in time, resulting in frequent bubbling at the liquid collecting port 271 and the problem of dirty liquid sputtering, as shown in Figure 11. As shown, at least a part of the liquid collecting port 271 can be located on the blocking wall 273, so that the inside of the liquid collecting cavity 213 is caused to be squeezed out from the roller brush and flow to the liquid collecting port 271 along the liquid guiding wall 274. It can communicate with the outside of the liquid collecting chamber 213 through the part of the liquid collecting port 271 on the blocking wall 273. As the dirty liquid flows into the liquid collecting chamber 213, the gas in the liquid collecting chamber 213 can face each other from the liquid collecting port 271. The upper area escapes, which can also increase the collection speed of the dirty liquid, and can prevent the problem of splashing when the dirty liquid flows from the liquid conducting wall 274 to the blocking wall 273, and the collision with the blocking wall 273 is relatively large. .

Specifically, a part of the liquid collection port 271 can be provided on the blocking wall 273, and another part of the liquid collection port 271 can be provided on the liquid guiding wall 274, which allows the dirty liquid to be collected to the collection more quickly under the action of gravity. In the liquid cavity 213.

Further, the blocking wall 273 may be a flared structure, and the blocking wall 273 is directed toward the roller brush that cooperates with the blocking wall 273. The blocking wall 273 includes a first diversion section 273a and a second diversion section 273b, and the liquid collection port 271 is located at the second diversion section 273b. Between a diversion section 273a and a second diversion section 273b, optionally, both the first diversion section 273a and the second diversion section 273b can be arranged obliquely with respect to the moving direction of the roller brush to form a diversion effect.

When the barrier wall 273 adopts the above structure, the barrier wall 273 also has a diversion function, so that when the dirty liquid flows to the barrier wall 273 under the guidance of the liquid guide wall 274, the first diversion section 273a and the second diversion section 273a While the flow section 273b provides a barrier for the dirty liquid, it can also guide the dirty liquid on both sides of the liquid collecting port 271 to flow to the liquid collecting port 271, so as to further increase the speed of collecting the dirty liquid.

In the direction perpendicular to the circumferential direction of the roller brush, the size of the side of the liquid-conducting wall 274 away from the blocking wall 273 can be similar to the length of the roller brush, so as to ensure that the dirty liquid at any position on the roller brush can be self-guided. The liquid wall 274 flows to the liquid collecting port 271. The first diversion section 273a and the second diversion section 273b can be arranged approximately symmetrically, so as to ensure that the dirty liquid squeezed out from different positions on the roller brush can evenly flow into the liquid collection cavity 213 from the liquid collection port 271.

Optionally, as shown in FIGS. 5-7, the dirty liquid accommodating mechanism 200 may further include an upper cover 260, and the upper cover 260 is provided on the side of the top cover part 270 away from the liquid collecting part 210, so as to prevent The liquid contained in the liquid collection cavity 213 splashes from the liquid collection port 271; and the upper cover 260 can also cover the liquid collection cavity 213 containing sewage and other liquids, which improves the overall appearance of the entire cleaning equipment during use to further enhance The user experience of the product. Specifically, the upper cover 260 may be connected to the liquid collecting part 210 or the top cover part 270. Of course, the upper cover 260 may also be directly connected to the housing 100.

More specifically, as shown in FIG. 3, in the case where the dirty liquid containing mechanism 200 is located between the front rolling brush 310 and the rear rolling brush 320, the upper cover 260 can be placed on the side where the forward rolling brush 310 and the rear rolling brush 320 are at the same time. Extend, so that the upper cover 260 can also cover a part of the front roller brush 310 and the rear roller brush 320, play the role of shielding the front roller brush 310 and the rear roller brush 320, and prevent adsorption on the front roller brush 310 and the rear roller brush 320 The liquid splashes with the rotation of the front rolling brush 310 and the rear rolling brush 320.

In order to further prevent the liquid collected in the liquid collection cavity 213 from splashing from the liquid collection port 271 when the entire cleaning device moves, preferably, as shown in FIG. 6, the cleaning device disclosed in the present invention may also include a splash-proof flange. 250. The splash-proof flanging 250 is connected to the side of the upper cover 260 facing the liquid collecting portion 210. As shown in FIG. The blocking walls 273 are attached to each other. Furthermore, during the operation of the cleaning device, the splash-proof flange 250 can provide a certain shielding effect on the liquid collection port 271, which can basically prevent the sewage and other liquid contained in the liquid collection cavity 213 from flowing out or flowing out with the movement of the cleaning device. Splash to ensure that the cleaned surface will not be re-contaminated. In addition, the contact area between the splash-proof flange 250 and the top cover 270 is relatively large. During the working process of the cleaning device, the top cover 260 will not be separated from the top cover 270, thereby further preventing the self-collection of dirty liquid. The liquid port 271 splashed out.

Specifically, the splash-proof flanging 250 may be fixed on one side surface of the upper cover 260 by means of bonding or thermal welding, or the splash-proof flanging 250 and the upper cover 260 may be formed in an integral manner. The specific size of the splash-proof flanging 250 can be determined according to the actual situation, and when the splash-proof flanging 250 and the liquid collecting port 271 cooperate with each other, it is necessary to ensure that the liquid collecting port 271 can communicate with the outside of the liquid collecting cavity 213 to The liquid squeezed from the front rolling brush 310 and the rear rolling brush 320 is collected. In addition, when a plurality of liquid collection ports 271 are provided, a splash-proof flange 250 may be designed corresponding to the plurality of liquid collection ports 271 to prevent any liquid such as sewage from being splashed at each liquid collection port 271.

Optionally, the outer circumference of the liquid collecting part 210 may be a square structure, which makes the liquid collecting part 210 better cooperate with the front roller brush 310, the rear roller brush 320, and the end cover 120 in the housing 100, and clean The overall appearance of the equipment is relatively square, and the cleaning equipment of this structure has a relatively good cleaning effect on the corners of the house and other areas; and the cleaning equipment of this structure has relatively high aesthetics, which can enhance the competitiveness of the product.

Considering that in the cleaning process, a single adsorption may not be able to absorb the clean water or sewage attached to the cleaned surface more thoroughly. Therefore, as shown in FIG. 3 and FIG. 5, the multiple roller brushes of the cleaning device disclosed in the present invention In the moving direction of the rolling brush, the front rolling brush 310 is located in front of the rear rolling brush 320; at the same time, at least a part of the projection of the front rolling brush 310 is located on the rear rolling brush 320. In the projection, it is ensured that the movement trajectory of the rear roller brush 320 can cover at least a part of the movement trajectory of the front roller brush 310, so that the cleaned surface adsorbed by the front roller brush 310 can be adsorbed and cleaned by the rear roller brush 320 again. The amount of water remaining on the cleaned surface is further reduced, and even the cleaned surface wiped by the rear roller brush 320 almost remains without water.

In addition, when the front roller brush 310 and the rear roller brush 320 are provided, the front roller brush 310 can perform preliminary cleaning on the surface to be cleaned. While cleaning most of the stains on the surface to be cleaned, it can also Part of the sewage is absorbed and collected in the cleaning part 330; and the rear roller brush 320 can perform secondary cleaning on the cleaned surface after the front roller brush 310 is cleaned, which can improve the cleaning effect of the cleaning equipment on the cleaned surface; The roller brush 320 can also perform secondary adsorption on the residual sewage on the cleaned surface to further reduce the amount of sewage stored on the cleaned surface. In some cases, it can even make the cleaned surface basically free of sewage. It can prevent the user from stepping on the cleaned surface that has just been wiped and cleaned, and stains will stick to the wet cleaned surface again. On the other hand, it can reduce the slippery degree of the cleaned surface, and reduce or even eliminate the user’s newly wiped cleaned surface. There is a risk of slipping when walking on the clean surface.

Further, as shown in FIGS. 3 and 4, the mounting portion 340 may be provided with an inner cavity 341, and in the process of assembling the cleaning device, the driving mechanism 400 is installed in the inner cavity 341, so that the mounting portion 340 can be driven The mechanism 400 provides a certain degree of protection; at the same time, by incorporating the driving mechanism 400, the safety threat generated by the driving mechanism 400 rotating at a high speed when cleaning equipment is used for cleaning can be reduced.

Optionally, as shown in FIG. 4, the driving mechanism 400 may include a motor 410, a driving button 420, and a bearing 430. The driving button 420 may be fixedly connected to the middle of the mounting portion 340 along its own axial direction. In this way, the motor 410 is used to drive the mounting portion. The way in which the middle part of the 340 rotates the entire roller brush can make the force of the motor 410 acting on the mounting part 340 relatively even, so that the mounting part 340 can generate a rotating motion more stably. In addition, with the above structure, along the width direction of the cleaning device, the proportion of the cleaning part 330 in the entire cleaning device can be increased to a certain extent, so that the cleaning efficiency of the cleaning device can be improved when the cleaning device is fixed.

Specifically, the motor 410 includes a casing 411 and a drive shaft 412. During the operation of the motor 410, the drive shaft 412 rotates relative to the casing 411. The housing 411 can be fixedly connected to the housing 100 of the cleaning device, and the housing 411 can also be connected to the mounting portion 340 through the bearing 430. Specifically, the housing 411 can be inserted into the inner ring of the bearing 430, and The outer ring of the bearing 430 is fixed to the inner surface of the mounting portion 340 to ensure that the mounting portion 340 has the ability to rotate relative to the casing 411. The drive shaft 412 can be fixedly connected with the drive button 420, so that when the drive shaft 412 rotates, the mounting portion 340 fixed to the drive button 420 can be driven to rotate, so as to achieve the purpose of driving the roller brush to rotate. In addition, since the casing 411 is connected to the mounting portion 340 through the bearing 430, and the casing 411 is fixedly connected to the casing 100, even if the mounting portion 340 rotates, the casing 411 and the casing 100 can be kept relatively stationary.

More specifically, as shown in FIG. 9, the housing 100 may include a housing body 110 and an end cover 120. The opposite sides of the housing body 110 are provided with end covers 120, and the end cover 120 is connected to the housing body 110. Both the driving mechanism 400 can be arranged between the two end caps 120. As shown in FIG. 4, the casing 411 can be fixedly connected to the end cover 120, and the drive shaft 412 can extend into the inner cavity 341 of the mounting portion 340 to be fixed with the drive button 420. The driving button 420 and the mounting portion 340 may be formed in an integral manner to improve the reliability of the connection relationship between the driving button 420 and the mounting portion 340.

In order to ensure higher stability of the rotation movement of the mounting portion 340, preferably, as shown in FIG. The rotation process of the part 340 provides a stabilizing effect. Specifically, as shown in Figure 4, another bearing 430 can be connected to the side of the drive button 420 away from the motor 410, the outer ring of the bearing 430 can be fixed to the inner surface of the mounting portion 340, and the inner ring of the bearing 430 can be connected to the end The cover 120 is fixed to ensure that the mounting portion 340 can rotate relative to the end cover 120, which further improves the reliability of the entire roller brush when it rotates.

Alternatively, the driving mechanism 400 may also have other structures, and the purpose of driving the mounting portion 340 can be achieved through other connection methods. Optionally, the driving mechanism 400 may include a stator and a rotor. The stator of the motor 410 may be connected to the housing 100 of the cleaning device, and the rotor may be connected to the mounting part 340. In this case, the driving mechanism 400 may also realize the driving of the mounting part. The purpose of 340 rotation. Specifically, the stator may be fixedly installed on the end cover 120 of the housing 100, and the rotor may be connected with the installation part 340. The assembly method of this driving mechanism 400 is relatively simple, and the cost of spare parts and installation is relatively low.

Further, there may be a plurality of driving mechanisms 400, and the plurality of driving mechanisms 400 may be matched with a plurality of roller brushes in a one-to-one correspondence. In this case, each roller brush can have the ability to operate autonomously, so that under the power provided by the driving mechanism 400, the interaction force between each roller brush and the surface to be cleaned can be greater, so as to further improve the overall cleaning. The cleaning effect of the equipment. At the same time, under the action of multiple driving mechanisms 400, it is also possible to prevent a failure of a single driving mechanism 400 from affecting the normal operation of the entire cleaning device.

Specifically, the structure of each driving mechanism 400 may be completely the same, and connected to the mounting portion 340 by the same or similar installation method, or the structures of multiple driving mechanisms 400 may also be different from each other, and different driving mechanisms 400 may be different from each other. The connection modes between the different mounting parts 340 may also be different from each other. Considering the brevity of this article, the description will not be repeated here. Those skilled in the art can determine the difference between the driving mechanism 400 and the mounting part 340 of different structures according to the above-mentioned embodiments. Connection method.

More specifically, each of the plurality of roller brushes may be provided with an inner cavity 341, and then a plurality of driving mechanisms 400 may be respectively installed in the inner cavity 341 of the plurality of roller brushes, which makes the driving structure of the entire cleaning device not exposed. Further improve the safety performance of the entire cleaning equipment.

Considering that during the cleaning process, the area contacted by the rear roller brush 320 is the area that the front roller brush 310 has already cleaned. Therefore, compared with the rear roller brush 320, the area contacted by the front roller brush 310 is relatively dirty. In order to further improve the cleaning effect of the entire cleaning equipment, the linear speed of the front roller brush 310 can be made greater than the linear speed of the rear roller brush 320, which makes the relative movement speed between the front roller brush 310 and the surface to be cleaned larger, and thus can be more Easily and more thoroughly remove the stains attached to the cleaned surface.

Specifically, in the case where only one driving mechanism 400 is provided, the driving mechanism 400 can be directly connected to the front roller brush 310, and the front roller brush 310 is driven to rotate by the driving mechanism 400, and the rear roller brush 320 is positioned on the front roller brush 310. When driving the downward movement, since the rear roller brush 320 needs to rotate against resistance, it can be ensured that the linear speed of the front roller brush 310 is greater than the linear speed of the rear roller brush 320. In the case where the front roller brush 310 and the rear roller brush 320 are both equipped with a driving mechanism 400, and the structure and size of the front roller brush 310 and the rear roller brush 320 are the same, it can be matched with the front roller brush 310 The rotational speed of the driving mechanism 400 is greater than the rotational speed of the driving mechanism 400 connected to the rear roller brush 320 to ensure that the linear speed of the front roller brush 310 is greater than that of the rear roller brush 320; for another example, when the rotational speeds of the driving mechanisms 400 are the same Next, the circumference of the rear rolling brush 320 may be greater than the circumference of the front rolling brush 310. Of course, through the combination of the foregoing methods, the linear velocity of the front rolling brush 310 can also be made greater than the linear velocity of the rear rolling brush 320.

Alternatively, in some cases, the linear velocity of the rear rolling brush 320 may be greater than the linear velocity of the front rolling brush 310. In this case, the relative movement speed between the rear roller brush 320 and the surface to be cleaned is relatively large, so that the sewage on the surface to be cleaned by the front roller brush 310 can be swept by the rear roller brush 320 when the rear roller brush 320 rotates multiple times. Faster and more thorough adsorption, thereby further reducing the slippery degree of the cleaned surface wiped by the cleaning device disclosed in the present invention, and can also produce a certain polishing effect on the cleaned surface, and improve the smoothness of the cleaned surface. Specifically, how to control the linear velocity of the rear roller brush 320 to be greater than the linear velocity of the front roller brush 310 may be similar to the previous embodiment, and considering the brevity of the text, it will not be repeated here.

In addition, the cleaning device disclosed in the present invention may also be provided with a control mechanism, which may be connected to each driving mechanism 400, so that the user can control the respective linear speeds of the front roller brush 310 and the rear roller brush 320 under different conditions.

In order to further improve the processing and assembly efficiency of the entire cleaning equipment and reduce costs, preferably, as shown in FIG. 3, the number of roller brushes may be two, and the two roller brushes may be the front roller brush 310 and the rear roller brush 320, respectively. Among them, the front rolling brush 310 mainly plays the role of cleaning and adsorbing sewage, and the rear rolling brush 320 mainly plays the role of secondary cleaning and wiping the cleaned surface. In order that the cleaned surface wiped by the front roller brush 310 can basically be wiped again by the rear roller brush 320, preferably, in the moving direction of the roller brush, the projection of the front roller brush 310 and the projection of the rear roller brush 320 can be made Because the front roller brush 310 and the rear roller brush 320 rotate in the same direction, in this case, it can be basically ensured that all the cleaned surfaces wiped by the front roller brush 310 can be wiped again by the rear roller brush 320, so that the The cleaning effect on all parts of the cleaning surface is relatively high, and the degree of slippery is relatively low.

Specifically, the structure and size of the front roller brush 310 and the rear roller brush 320 can be made correspondingly the same, and the ends of the front roller brush 310 and the rear roller brush 320 can be aligned in the moving direction, and the front roller brush 310 and the rear roller brush 320 can be aligned in the moving direction. When the rotation direction of the brush 320 is the same, this can basically ensure that the rear roller brush 320 can completely move along the movement track of the front roller brush 310, so that the cleaned surface wiped by the front roller brush 310 can be wiped twice. It should be noted that in order to improve the cleaning effect, the cleaning part 330 can be made of a softer fiber material. The cleaning part 330 of the front roller brush 310 or the rear roller brush 320 is tilted, which causes the front roller brush to move forward in the moving direction. The projections of the rolling brush 310 and the rear rolling brush 320 are slightly non-overlapping, which is also in the protection scope of the embodiment of the present invention.

In addition, the front roller brush 310 and the rear roller brush 320 having the same structure and size are convenient for spare parts work. At the same time, when the cleaning part 330 of the front roller brush 310 and/or the rear roller brush 320 is dirty or damaged, it can The cleaning part 330 of the same structure is replaced with the front roller brush 310 and/or the rear roller brush 320 mounting part 340, which reduces the maintenance cost of the entire cleaning device and improves the ease of use of the entire cleaning device.

In addition, when the structure and size of the front roller brush 310 and the rear roller brush 320 are the same, the center of gravity of the entire cleaning device is relatively centered, so that the size of one of the two is larger than that of the other. The interaction force between one and the surface to be cleaned is much smaller than the interaction force between the other and the surface to be cleaned, thereby reducing the cleaning or drying effect of the surface to be cleaned. When the structure and size of the front roller brush 310 and the rear roller brush 320 are the same, the load-bearing capacity of the two is relatively balanced, which can ensure that the interaction force between the front roller brush 310 and the rear roller brush 320 and the surface to be cleaned is basically Similarly, to a certain extent, the cleaning and drying effect of the entire cleaning equipment on the opposite side can be improved.

In order to further reduce the number of parts in the cleaning equipment, to reduce the overall size of the cleaning equipment, to make the cleaning equipment more convenient to use, and can enter the area with relatively small gaps for cleaning work, optionally, as shown in Figure 3 As shown, the dirty liquid holding mechanism 200 may be provided with only one, in order to ensure that the sewage adsorbed by the front rolling brush 310 and the rear rolling brush 320 can be collected into the dirty liquid holding mechanism 200 to improve the dryness of the cleaned surface after cleaning. To a certain extent, preferably, in the process of designing and assembling the front rolling brush 310 and the rear rolling brush 320, a predetermined interval can be provided between the front rolling brush 310 and the rear rolling brush 320, so that the dirty liquid containing mechanism 200 can be installed on the front. Between the rolling brush 310 and the rear rolling brush 320, it is ensured that both the front rolling brush 310 and the rear rolling brush 320 can cooperate with the dirty liquid containing mechanism 200 to squeeze and discharge the absorbed sewage and other liquid into the dirty liquid containing mechanism 200 , To prevent the front roller brush 310 and the rear roller brush 320 from being in contact with the surface to be cleaned from already adsorbing more liquid, and to improve the dryness of the surface to be cleaned after being wiped.

Based on the above-mentioned embodiment, as shown in FIG. 11, the number of liquid collection ports 271 can be two, and one liquid collection port 271 can be set toward the front roller brush 310 while the other liquid collection port 271 is directed toward the rear roller brush. 320 is set to ensure that liquids such as water absorbed by the front rolling brush 310 and the rear rolling brush 320 can be collected in the liquid collection cavity 213. In the case where two liquid collection ports 271 are provided, both liquid collection ports 271 can be located in the middle of the top cover portion 270, and further, the two liquid collection ports 271 can be arranged opposite to each other on the top wall 272. On both sides, it is ensured that the distance between the plurality of liquid collection ports 271 and the surface to be cleaned is relatively large.

In order to further improve the cleaning effect of the cleaning device, preferably, as shown in FIG. 1, the cleaning device disclosed in the present invention may further include a handle 510 installed on the housing 100. In the case that the cleaning device is provided with a handle 510, the user can apply a set force to the housing 100 through the handle 510 when the user uses the cleaning device to clean the surface to be cleaned. The brushes 320 are connected to the housing 100, so that the interaction force between the front roller brush 310 and the rear roller brush 320 and the surface to be cleaned can be increased to a certain extent, which can further increase the cleaning equipment's impact on the surface to be cleaned. Cleaning effect and drying effect.

In addition, when the handle 510 is provided, it is also convenient for the user to operate the entire cleaning device, so as to clean the area with more or more stubborn stains on the surface to be cleaned multiple times, and the entire cleaning device can also be operated More precise cleaning of corners or crevices can further enhance the ease of use of cleaning equipment and enhance user experience.

Specifically, the length and shape of the handle 510 can be determined according to actual needs. Preferably, the handle 510 can be a cylindrical rod-shaped structure, and the handle 510 of this structure is convenient for the user to grasp. The handle 510 can be hinged to form a reliable connection with the housing 100. In order to further improve the ease of use of the entire cleaning device, preferably, a reliable connection relationship can be formed between the handle 510 and the housing 100 through a universal shaft 520, which can further improve the ease of use of the cleaning device.

In order to further improve the ease of use and the scope of application of the cleaning equipment, preferably, as shown in Figures 7-10, an escape notch 215 may be formed on the liquid collecting part 210, and during the process of installing the handle 510, the handle 510 Part of it is located at the avoidance gap 215, so that when the handle is connected to the housing 100 through the universal shaft 520, the handle 510 can be tilted at a greater angle with respect to the housing, and the handle 510 can even be parallel to the ground, thereby facing the sofa. Perform cleaning work underneath, under the bed, and under the table.

In the case where the liquid collecting part 210 is provided with the avoidance notch 215, as shown in FIG. 10, the liquid collecting part 210 includes a first liquid collecting area 211 and a second liquid collecting area 212, and the first liquid collecting area 211 and the second liquid collecting area The areas 212 are respectively located on opposite sides of the avoidance notch 215, which makes the avoidance notch 215 between the front roller brush 310 and the rear roller brush 320 more centered relative to the housing 100 to further enhance the handle 510 installed at the avoidance notch 215 Easy to operate. At the same time, the first liquid collecting area 211 and the second liquid collecting area 212 can be matched with the front rolling brush 310 and the rear rolling brush 320. In this case, the entire liquid collecting portion 210 can be better collected from the front rolling brush 310. And the sewage and other liquids squeezed out from the back rolling brush 320.

Specifically, the liquid collecting portion 210 may be formed of plastics and other materials in an integral molding manner, and by connecting the first liquid collecting area 211 and the second liquid collecting area 212 to each other, the process of disassembling and assembling the liquid collecting portion 210 is more convenient. The volume of the first liquid collection area 211 and the second liquid collection area 212 can be determined according to the actual situation. The size of the mating part of the rolling brush 310 and the rear rolling brush 320 is basically the same, so that the amount of sewage collected by the first liquid collecting area 211 and the second liquid collecting area 212 is the same or similar, preventing the cleaning equipment from working. It may happen that one of the first liquid collection area 211 and the second liquid collection area 212 has been filled or even overflowed, while the other has not been filled.

Moreover, in the case where the liquid collecting portion 210 includes the first liquid collecting area 211 and the second liquid collecting area 212, the number of the top cover portion 270 may be two, and any top cover portion 270 may be provided with at least two A collection port 271. Taking the top cover part 270 matched with the first liquid collecting area 211 as an example, one of the two liquid collecting ports 271 is set toward the front roller brush 310, and the other is set toward the rear roller brush 320, so as to ensure that the front roller brush 310 and The liquid extruded by the rear rolling brush 320 can be collected into the first liquid collection area 211 through the corresponding liquid collection port 271; accordingly, the top cover portion 270 corresponding to the second liquid collection area 212 can also be provided with At least two liquid collection ports 271 are respectively arranged toward the front rolling brush 310 and the rear rolling brush 320. Similarly, the liquid collection port 271 on each top cover part 270 is provided in the middle of the top cover part 270.

In addition, as shown in FIG. 8, two push buttons 216 may also be provided, and the two push buttons 216 may be respectively arranged on the top cover 270 corresponding to the first liquid collection area 211 and the second liquid collection area 212 to lift How easy it is to detach each top cover part 270.

In order to make the amount of sewage collected by the first sump 211 and the second sump 212 more balanced, preferably, the first sump 211 and the second sump 212 can be connected to each other, in this case Even if more sewage and other liquids flow into the first liquid collection area 211 at the same time, since the first liquid collection area 211 and the second liquid collection area 212 are connected to each other, the first liquid collection area 211 and the second liquid collection area 211 will not appear. The amount of liquid remaining in the second liquid collection area 212 differs too much.

Specifically, in the direction of gravity, the bottoms of the first liquid collection area 211 and the second liquid collection area 212 can be connected to each other, or the first liquid collection area 211 and the second liquid collection area 212 can be made from bottom to top. The connecting structure is to increase the flow rate of the dirty liquid between the first liquid collecting area 211 and the second liquid collecting area 212. Optionally, a cavity can be formed in the structure where the first liquid collection area 211 and the second liquid collection area 212 are connected to each other, so as to communicate the first liquid collection area 211 and the second liquid collection area 212 through the cavity. The number of connecting structures between the first liquid collection area 211 and the second liquid collection area 212 is further reduced.

In the case that the first liquid collection area 211 and the second liquid collection area 212 are in communication with each other, the first liquid collection area 211 and the second liquid collection area 212 are both equipped with a top cover portion 270, and any second diversion section 273b are all located between the first diversion section 273a and the avoidance gap 215. Optionally, in the direction perpendicular to the circumferential direction of the roller brush, the size of the second diversion section 273b is smaller than the size of the first diversion section 273a.

With the above structure, when the cleaning equipment is tilted, the dirty liquid contained in the first liquid collection area 211 and the second liquid collection area 212 will first flow to the lower one. For example, in the direction of gravity, if the first liquid collection area 211 is lower than the second liquid collection area 212, the dirty liquid in the second liquid collection area 212 will first collect in the first liquid collection area 211, and the first liquid collection area 211 The amount of dirty liquid in the liquid area 211 is greater than the amount of dirty liquid in the second liquid collection area 212. In this case, as shown in FIG. 11, the amount of dirty liquid that can be stored in the first liquid collection area 211 is related to the size of the first diversion section 273a in the direction A, and the amount of dirty liquid that can be stored in the second liquid collection area 212 The amount of dirty liquid is related to the size of the second diversion section 273b in the direction A, compared to the size of the first diversion section 273a being less than or equal to the size of the second diversion section 273b, by making the first diversion section 273b The size of the flow section 273a is larger than the size of the second diversion section 273b, which can make the amount of dirty liquid stored in the first liquid collection area 211 and the second liquid collection area 212 relatively large, thereby preventing the occurrence of cleaning equipment when the cleaning equipment is tilted. The problem of dirty liquid splashing.

In addition, the volume of the liquid collection chamber 213 can be enlarged by making the top cover part 270 protrude away from the liquid collecting part 210. This can also solve the problem of dirty liquid splashing when the cleaning equipment is tilted to a certain extent. . Specifically, the distance between the top wall 272 and the bottom of the liquid collection portion 210 can be increased, so that the volume of the liquid collection cavity 213 can be increased.

During the working process of the cleaning equipment, since the front roller brush 310 has priority over the rear roller brush 320 to adsorb the sewage on the surface to be cleaned, at the same time, the amount of sewage absorbed in the front roller brush 310 is usually greater than that of the rear roller brush. The amount of sewage absorbed in the roller brush 320, and then under the action of the front wiper strip and the rear wiper strip, the amount of sewage squeezed out from the front roller brush 310 is greater than the amount of sewage squeezed out from the rear roller brush 320. In order that the sewage squeezed out of the front rolling brush 310 can be better collected in the liquid collecting part 210, preferably, as shown in FIG. 320 side.

In this case, since the side of the liquid collecting part 210 close to the front rolling brush 310 is not provided with the avoidance notch 215, the sewage squeezed out from the front rolling brush 310 can enter the second side through the side with a relatively large cross-sectional area. A liquid collection area 211 and a second liquid collection area 212 ensure that a large amount of sewage squeezed out of the front rolling brush 310 can be collected into the liquid collecting portion 210 quickly; at the same time, due to the sewage absorbed by the rear rolling brush 320 itself The amount is relatively small. Therefore, although the avoidance gap 215 occupies a part of the liquid collecting part 210, the sewage squeezed out of the rear roller brush 320 will not flow into the first liquid collecting area 211 and the second liquid collecting area 212. A greater adverse effect, therefore, the liquid collection part 210 of this structure can ensure that the sewage squeezed out by the front rolling brush 310 and the rear rolling brush 320 can be collected quickly and completely.

As described above, the front rolling brush 310 and the rear rolling brush 320 can be squeezed with the dirty liquid containing mechanism 200 to collect the sewage and other liquids absorbed by the front rolling brush 310 and the rear rolling brush 320 to the dirty liquid containing mechanism. 200 in. Of course, other methods can also be used to collect the liquid adsorbed by the front roller brush 310 and the rear roller brush 320, such as vacuum suction. Considering the conciseness of the text, it will not be listed here.

Further, the dirty liquid accommodating mechanism 200 may also include a liquid wiper strip, and at least one of the front roller brush 310 and the rear roller brush 320 may be equipped with a wiper strip, so that the wiper strip further lifts the dirty liquid from the roller brush. Speed and thoroughness.

Optionally, as shown in FIG. 3, a front wiper strip 220 can be provided for the front roller brush 310, and the front wiper strip 220 is press-fitted with the front roller brush 310, so as to lift the liquid in the front roller brush 310 to be squeezed. The thoroughness of the discharge enables the front roller brush 310 to absorb more sewage in the subsequent wiping and cleaning process, and as the rotation process of the front roller brush 310 progresses, the sewage and other liquids on the front roller brush 310 can be immediately squeezed. Out to the liquid collecting part 210, this can prevent the surface to be cleaned wiped by the front roller brush 310 from becoming too wet and slippery.

When the front roller brush 310 rotates counterclockwise to make the cleaning device have a tendency to move forward, the front wiper strip 220 may be arranged on the side of the front roller brush 310 close to the liquid collecting part 210, specifically, the front wiper strip 220 can extend along most of the front roller brush 310, and part of the front wiper strip 220 is press-fitted with the front roller brush 310, so that after the front roller brush 310 absorbs liquid, as the front roller brush 310 rotates, the The front wiper strip 220 squeezes out the liquid absorbed by the front roll brush 310 by squeezing it with the front roll brush 310, and the liquid squeezed from the front roll brush 310 can flow on the surface of the front roll brush 310. , And finally flow into the liquid collecting cavity 213 through the liquid collecting port 271. Optionally, the front liquid wiper strip 220 may be connected to the upper cover 260 through a connecting structure, or the front liquid wiper strip 220 and the upper cover 260 may be integrally formed.

Furthermore, the liquid collection part 210 can be arranged as close as possible to the front liquid wiper strip 220, so that the liquid squeezed from the front liquid wiper strip 220 can flow into the liquid collection portion 210 faster and more thoroughly, and prevent liquids such as sewage from leaving the front liquid wiper. After rolling the brush 310, spattering occurs, or it flows out of the cleaning device, or even flows directly to the surface to be cleaned, which affects the cleaning effect of the surface to be cleaned.

Further, the liquid collecting part 210 for collecting sewage and other liquids may form a detachable connection with the housing 100. In this case, when the sewage in the liquid collecting cavity 213 needs to be drained, only the collecting The liquid part 210 is detached from the housing 100, and the liquid collecting part 210 is cleaned separately, which further improves the convenience of use of the cleaning equipment. In order to facilitate the removal of the liquid collecting part 210 from the housing 100, preferably, as shown in FIG. 11, a handle 217 may be further provided on the liquid collecting part 210. The difficulty.

Optionally, as shown in FIG. 11, the dirty liquid containing mechanism 200 may further include a liquid guiding part 230, which may be connected to the liquid collecting part 210, and may be equipped with a liquid guiding part 230 for the front wiper strip 220 Furthermore, in the process of extruding and fitting the front liquid strip 220 and the front rolling brush 310, the liquid guiding part 230 can be used to guide the squeezed sewage and other liquids, which allows the sewage to pass through the collecting liquid faster and more directly. The port 271 flows into the liquid collection cavity 213. At the same time, in the process from when sewage and other liquids are squeezed out to after flowing into the liquid collecting cavity 213, the liquid guide 230 can also prevent the sewage and other liquids from being sucked into the front roller brush 310 again, which can make the front roller brush The sewage in 310 can be squeezed out more thoroughly to further improve the cleanliness and dryness of the cleaned surface after wiping.

Optionally, the liquid guiding portion 230 can be formed by obliquely extending the side wall of the liquid collecting portion 210 to reduce the difficulty of formation and installation of the liquid guiding portion 230, and in the direction of gravity, by making the liquid guiding portion 230 and the front The upper part of the rolling brush 310 on the side close to the liquid collecting portion 210 is matched with each other, so that the liquid guiding portion 230 can not only provide a guiding effect, but also can squeeze with the front rolling brush 310 to further extrude the adsorbed in the front rolling brush 310 Dirty liquid.

Furthermore, after working for a period of time, the amount of liquids such as sewage and the like absorbed in the rear roller brush 320 may also be relatively large. It may be more difficult to squeeze only by means of squeezing it with the side wall of the liquid collecting part 210. Roll the sewage in 320 after exiting. In order to ensure that the dirty liquid absorbed by the rear roller brush 320 can be quickly and completely collected into the liquid collection chamber 213, when the front roller brush 310 and the rear roller brush 320 are both equipped with a driving mechanism 400, the forward roller The brush 310 rotates counterclockwise, and the rear roller brush 320 rotates clockwise, so as to equip the front roller brush 310 and the rear roller brush 320 with a wiper strip at the same time.

Specifically, similar to the front liquid wiper bar 220, the position of the rear liquid wiper bar 240 corresponds to the position of the front liquid wiper bar 220, that is, the rear liquid wiper bar 240 may be disposed at the rear roller brush 320 near the liquid collecting part 210. One side, the rear liquid wiper strip 240 can extend along most of the rear roller brush 320, and a part of the rear wiper liquid strip 240 can be squeezed and fitted with the rear roller brush 320 to rotate clockwise after the rear roller brush 310 absorbs liquid. In the process, the rear wiper strip 240 can be squeezed with the rear roller brush 320 to squeeze out the liquid absorbed by the rear roller brush 320, and the liquid squeezed from the rear roller brush 320 can be attached to the rear roller brush. The surface of 320 flows, and finally flows into the liquid collecting cavity 213 through the liquid collecting port 271 corresponding to the rear rolling brush 320. In addition, the liquid guiding part 230 may also be provided for the rear liquid wiper strip 240, so that the dirty liquid squeezed out from the rear liquid wiper strip 240 can also be collected into the liquid collection cavity 213 relatively quickly and completely.
