Detailed Description

The following detailed description of embodiments of the utility model is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the utility model is not limited to the specific embodiments.

Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or components.

As shown in fig. 1 to 7, the cleaning apparatus 100 according to an embodiment of the present utility model includes a main body 10, a first roll brush body and a second roll brush body 30, and a dust suction port is provided at a bottom of the main body 10. Wherein the second roll brush body 30 is a front roll brush body located at the front end of the entire cleaning apparatus 100 (first roll brush body), and the second roll brush body 30 has a smaller diameter than the first roll brush body. Therefore, places such as corners or bottoms of walls can be cleaned, the coverage area and cleaning range of the cleaning apparatus 100 are enlarged, and the ease of use and the use effect are improved.

The second rolling brush body 30 comprises a center shaft 31 and a rubber sleeve 32 sleeved outside the center shaft 31. In order to prevent the relative movement between the two from affecting the cleaning effect, a matched convex strip and a matched groove are arranged between the middle shaft 31 and the rubber sleeve 32. The specific groove 311 is formed on the surface of the central shaft 31 in the axial direction, and the convex strip 322 is formed on the inner wall of the gum cover 32. Of course, the change can be performed, the groove is arranged on the inner wall of the rubber sleeve, and the convex strip is arranged on the outer wall of the center shaft, and the embodiment is not limited.

Further, a plurality of flexible adhesive tapes 321 are arranged on the outer surface of the rubber sleeve 32 in an array manner along the circumferential direction. The adhesive tape 321 is enabled to continuously scrape the ground through rotation, dirt is swept back, the first rolling brush body sweeps the dirt to the dust collection opening, and the dirt is sucked and removed to complete the cleaning process. It will be appreciated that the specific number of strips 321 may be provided as much as possible without affecting the rotation of the second roll brush body 30.

Although the glue strip 321 is flexible and bendable, there is still the possibility of not being completely covered when cleaning narrow locations. Thus, as shown in fig. 4 and 5, the glue strip 321 is formed with bends at its distal end, and all bends are oriented the same. When the second rolling brush body 30 rotates, the adhesive tape 321 can fully cover corners or the bottom of the wall body through the bending part, so that the condition of cleaning in place is avoided.

If the direction of bending of the adhesive tape 321 is the same as the cleaning direction, there is a case where the area such as a corner cannot be covered or dirt is brought into the area inside the bending portion during cleaning and cannot be sucked through the dust suction port. Therefore, the bending direction of the adhesive tape 321 is opposite to the rotating direction of the second rolling brush body 30 in the operating state.

The second roll brush body 30 needs to be miniaturized as much as possible because it needs to be positioned as close to a corner or the like as possible. Preferably, in this embodiment, the diameter of the second rolling brush body 30 is less than 30mm. Meanwhile, it should be understood that when the second rolling brush 30 directly abuts against the wall, the length from the bending portion to the surface of the second rolling brush 30 of the adhesive tape 321 can at least reach the bottom corner, so as to complete the complete cleaning of the bottom of the wall.

To further improve the cleaning effect, the first rolling brush body comprises a front rolling brush body 21 and a rear rolling brush body 22, and the dust collection opening is positioned between the front rolling brush body and the rear rolling brush body. The two rolling brush bodies are rotatably connected to the main body 10, an arc-shaped baffle plate 11 is cooperatively arranged above the rear roller brush body 22 in the main body 10, one end of the baffle plate 11 extends between the front rolling brush body 21 and the rear rolling brush body 22, the other end extends to the rear end of the main body 10, an outlet 12 is formed at the rear end, and the outlet 12 can be externally connected with a suction device.

A rear water deflector 13 is provided at the rear of the bottom rear rolling brush 22 of the main body 10, and a first water deflector 131 and a second water deflector 132 are provided on the rear water deflector 13. The first water baffle 131 is disposed above the rear water separator 13 and abuts against the surface of the rear rolling brush 22, and the second water baffle 132 extends downward and abuts against the ground in the working state.

With reference to fig. 3, in the above arrangement, the front rolling brush 21, the rear rolling brush 22, the baffle 11 and the outlet 12 together form a dust collection channel (indicated by arrows in the figure), and after dirt is swept between the front rolling brush 21 and the rear rolling brush 22, the dirt finally leaves the cleaning apparatus 100 through the outlet 12 by the baffle 11, and the dirt is sucked out by the rear water separator 13. The first water baffle 131 can remove the sewage adsorbed by the rear rolling brush body 22 by extrusion, so that the operation is prevented from being influenced by the overweight of the rear rolling brush body 22, and the second water baffle 132 plays roles of collecting sewage and scraping the ground, so that the cleaning is the final step.

It is conceivable that a front water deflector 14 is provided above the baffle 11 near the front roll brush 21, which is likewise provided with a third water deflector 141 abutting the front roll brush 21. The third water baffle 141 can reduce the weight of the sewage by extruding the sewage from the surface of the front rolling brush body 21; on the other hand, dirt can be prevented from returning to the position between the second rolling brush body 30 and the front rolling brush body 21 through the surface of the front rolling brush body 21, and a relatively airtight dust collection channel is formed by matching the second rolling brush body 30 and the front rolling brush body 21 with the baffle 11, so that the suction force is enhanced, and the dust collection effect is improved.

It is easy to think that the first water baffle 131, the second water baffle 132 and the third water baffle 141 are also made of flexible rubber, so that certain elastic deformation can be generated, and the flexibility is improved.

As can be seen from fig. 6 and 7, the front water separator 14 is identical to the rear water separator 13, a plurality of front water collecting ports 142 and rear water collecting ports 133 are respectively formed at the front end surfaces, and a front water outlet 143 and a rear water outlet 134, which can be externally connected to a water pipe, are provided at the rear ends. The external suction device is connected to the water outlet, and the sewage is pumped away through the water collecting ports so as to complete the cleaning process. The front water collecting port 142 and the rear water collecting port 133 arranged in an array can reduce the driving requirement on a power source, and meanwhile, the situation that foreign matters enter the water separator and block the internal channel to cause the water separator to fail can be avoided.

As shown in fig. 2, the main body part 10 includes a first support plate 15 and a second support plate 16, and a front roll brush body 21, a rear roll brush body 22, and a second roll brush body 30 are rotatably disposed between the two support plates. For easy disassembly and replacement, the second support plate 16 is designed to be a quick-release snap-fit type, and can be detached from the main body 10 more conveniently for replacement and maintenance of the rolling brush body.

Since the second roll brush body 30 and the front roll brush body 21 take more cleaning actions, relatively more cleaning replacement and maintenance are required, and relatively fewer rear roll brush bodies 22 are required. The second support plate 16 is thus designed as a front and rear part, wherein the rear plate 161 serves to fix the rear roll brush body 22 to the main body 10, and the second roll brush body 30 and the front roll brush body 21 are connected to the rear roll brush body by the front plate 162.

When the rotation is driven by the frictional force of the floor, there may be a case where the rotation efficiency and the cleaning effect are not high. In this embodiment, therefore, the second rolling brush body 30 is configured to be driven to rotate by the front rolling brush body 21, preferably by belt transmission, and has lighter structure, less transmission loss and higher efficiency. Specifically, the end portions on the same side of the second rolling brush body 30 and the front rolling brush body 21 are respectively connected with a first gear 33 and a second gear 211, and the two gears are connected through a belt.

As shown in fig. 1, 2 and 5, the central shaft 31 extends out of the front plate 162, and a first plane 313 is formed at an end portion thereof, and a corresponding second plane 331 is provided on the first gear 33, so that the first gear 33 is inserted and does not rotate relative to the central shaft 31, thereby improving the overall stability.

In the same way, the same plane structure is also arranged between the middle shaft of the front rolling brush body 21 and the second gear 211, so as to avoid relative rotation of the two, improve stability, and are not described herein again.

Further, for improving ease of use, an annular groove 312 is formed in the end of the central shaft 31 in the axial direction, and an annular protrusion (not shown) is fitted in the hole of the first gear 33. When inserted into the center shaft 31, the first gear 33 is elastically deformed to a certain extent, and the annular protrusion is inserted into the annular groove 312 to fix the first gear and the second gear axially. Also during removal, the annular projection is disengaged from the annular recess 312 by prying it outwardly with force against the first gear 33. The gear is arranged outside the supporting plate, so that the driving problem of the second rolling brush body 30 is solved, and meanwhile, a limiting structure is not required to be added between the rolling brush body and the supporting plate, and the fixing problem is solved.

It is conceivable that the fixing means described above can be used as well between the front roll brush body 21 and the front plate 162, and that it is simple and easy to handle.

In this embodiment, the cleaning apparatus 100 is a self-driven apparatus, and a motor is disposed inside the front rolling brush 21 to drive the front rolling brush to rotate, and the belt drives the second rolling brush 30 to rotate. Of course, a motor may also be provided in the rear roll brush body 22. The double-motor mode can reduce the load on a single motor, reduce the damage probability and prolong the service time.

In the present embodiment, the first gear 33 and the second gear 211 have the same size, and since the front rolling brush body 21 is larger than the second rolling brush body 30, even if the running speed is slower, the second rolling brush body 30 can reach a more ideal rotating speed in the use process, so as to achieve a better cleaning effect.

In this embodiment, the flexible adhesive tape 321 is used as a cleaning body with respect to the second rolling brush body 30, the front rolling brush body 21 and the rear rolling brush body 22 may be selectively provided on the surface with nap sleeves to clean the floor, and the nap thickness may be selected. When used on rougher floors (such as cement floors, etc.), coarser fluff may be selected; while finer pile can be selected when applied to a relatively flat ground surface (e.g., floor, etc.).

The foregoing descriptions of specific exemplary embodiments of the present utility model are presented for purposes of illustration and description. It is not intended to limit the utility model to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain the specific principles of the utility model and its practical application to thereby enable one skilled in the art to make and utilize the utility model in various exemplary embodiments and with various modifications as are suited to the particular use contemplated.
