Referring to fig. 1 to 13, the cleaning device provided in this embodiment may include a base 100, a rolling brush assembly 200, a dirt suction port 300, and a dirt suction channel located inside the cleaning device and communicated with the dirt suction port 300, where the cleaning device may clean dirt on the ground through the rolling brush assembly 200, and suck dirt on the ground through the dirt suction port 300, and the sucked dirt enters the dirt suction channel through the dirt suction port 300.

In the cleaning apparatus provided by the embodiment of the present invention, the roller brush assembly 200 is used for picking up solids and liquids on the ground, wherein, the roller brush assembly 200 comprises a roller brush 201, the rolling brush 201 can rotate around the first axis, the rolling brush assembly 200 cleans solid and liquid on the ground through the rolling brush 201, and the separation of the solid and the liquid is completed through the cooperation of the scraper. Specifically, based on that the rolling brush 201 can clean the solid and liquid on the ground only when the rolling brush 201 contacts with the ground, when the surface of the rolling brush 201 contacts with the ground for friction, the rolling brush 201 can adsorb the solid and liquid on the surface of the rolling brush 201, and along with the rotation of the rolling brush 201, specifically, in fig. 9 and fig. 11, the rotation direction of the rolling brush is counterclockwise, during the rotation process, the solid and liquid on the surface of the rolling brush 201 will leave the surface of the rolling brush 201 due to the gravity of the solid and liquid, while the solid and liquid that do not leave freely will rotate along with the rolling brush 201, and the surface of the rolling brush 201 with the adsorbed solid and liquid will pass through the area where the scraper assembly 400 is located, so that the solid and liquid are scraped from the surface of the rolling brush 201 and separated under the cooperation of the scraper assembly 400. It should be noted that the scraper assembly 400 is located above the soil pick-up port 300, and solid or liquid freely separated from the surface of the roller brush 201 and solid or liquid scraped from the surface of the roller brush 201 by the scraper assembly 400 are sucked into the soil pick-up passage by the soil pick-up port 300.

A water spray assembly 500 is used to apply liquid to the roll brush 201. In-process on cleaning device washs ground, the washing liquid that uses mainly is that the subassembly 500 that sprays water through among the cleaning device provides, and is concrete, be provided with a plurality of apopores 501 on the subassembly 500 that sprays water, apopore 501 is just setting up to the round brush 201, and be close to the surface of round brush 201, a plurality of apopores 501 are arranged along the axial of round brush 201 in proper order, apopore 501 passes through outlet pipe and connects in water supply installation (not shown in the figure), thereby pass through apopore 501 drainage to the round brush 201 surface with water supply installation's liquid.

In the related art, the cleaning device generally adopts the metal scraper to squeeze the roller brush 201 to scrape the sewage into the sewage suction port 300, but most of the cleaning devices fix the metal scraper, that is, the squeezing interference of the scraper to the roller brush 201 is fixed. When the cleaning device works, the fluff on the roller brush 201 is reduced in performances such as resilience, water absorption and the like as the service cycle is longer, resulting in the fluff loss of the roller brush 201. The amount of the squeeze of the roll brush 201 by the squeegee becomes small, the squeezing effect of the roll brush 201 becomes poor, and the ground surface has water marks.

Based on this, as shown in fig. 1 to 6, the scraper assembly 400 provided in the embodiment of the present invention is rotatably connected to the water spray assembly 500, and is provided with a driving member 600 for driving the plate body 401 to rotate relative to the water spray assembly 500.

The main structure of the scraper assembly 400 is a plate body 401, the plate body 401 is located below the water spray assembly 500, and the plate body 401 can rotate around a second axis, which is the rotation axis of the scraper assembly 400, and the second axis is parallel to the first axis. In addition, the plate body 401 is also a long strip-shaped structure extending along the axial direction of the roller brush 201, i.e. the first axial direction, and the extending length of the plate body 401 is consistent with the length of the roller brush 201, so that the full-face contact between the scraper assembly 400 and the roller brush 201 can be realized.

The driving member 600 is used for applying a force to the scraper assembly 400 to rotate towards the roller brush 201 so as to drive the plate 401 to rotate relative to the water spray assembly 500; under the driving action of the driving element 600, the plate body 401 has a first position and a second position, in the first position, the plate body 401 is always pressed against the rolling brush 201 under the driving action of the driving element 600, and the second position is a limit position which the scraper blade assembly 400 can reach under the action of the driving element 600 when the rolling brush 201 is not installed. When the rolling brush 201 is installed, the plate 401 is pressed by the rolling brush 201 and rotates from the second position to a direction away from the rolling brush 201. The embodiment of the utility model provides an among the cleaning equipment, change scraper blade subassembly 400 into the mode that can rotary movement by fixed mode, make first position be not an only fixed specific position in the whole life cycle of round brush, specifically, the diameter of round brush 201 constantly diminishes, corresponding removal also can take place for the first position of plate body 401, promptly along with the loss diameter of round brush 201 diminishes, rotatory scraper blade begins the subassembly and can remain the extrusion to round brush 201 at last, make under the longer condition of round brush 201 life cycle, the scraper blade still has fine wiping effect, the condition that the water mark appears after reducing the equipment use, ground resumes dry time and still keeps superiorly, the live time of single fine hair round brush 201 of extension, the overall performance has been promoted, user experience has been optimized.

In the above embodiment, the driving member 600 is used for providing an acting force which enables the plate body 401 to rotate relative to the water spraying assembly 500, so that the plate body 401 can always support and press on the surface of the rolling brush 201 with a constantly changing diameter, and the embodiment of the present invention does not make specific limitation, and all driving mechanisms which can realize the above functions are all applicable. Specific forms of the driving member 600 include, but are not limited to, a small driving motor, an elastic member, or a magnetic member, but the driving member 600 is preferably an elastic member or a magnetic member from the viewpoint of structural simplicity and power consumption.

In the case that the driving member 600 is an elastic member, the elastic member may be a coil spring, a torsion spring, a rubber spring, or the like, and the elastic member is pre-pressed and installed between the water spraying assembly 500 and the scraper assembly 400 to generate elastic deformation between the water spraying assembly 500 and the scraper assembly 400, and the plate 401 is driven by the elastic force to rotate relative to the water spraying assembly 500, in the state of the roller brush 201 being not installed, the plate 401 is driven by the elastic force to rotate to the second position, in the state of the roller brush 201 being installed, the plate 401 is pressed against the surface of the roller brush 201 by the elastic force, that is, the plate 401 is in the first position.

As shown in fig. 4 and 5, the elastic member as the driving member 600 is preferably a torsion spring, which has a small structure for easy installation and can provide a large driving force, for example, the torsion spring can be pre-loaded on the water spray assembly 500, and the scraper assembly 400 is provided with an installation position 403 for fixing one end of the torsion spring. Specifically, as shown in fig. 1, the plate body 401 extends along the direction of the first axis, two tabs 402 are respectively formed at two ends of the extending direction of the plate body 401, the two tabs 402 are located at the same side of the plate body 401 and are perpendicular to the plate body 401, the tabs 402 are rotatably connected with the water spray assembly 500 through a pivot 405, and the rotation axis of the pivot 405 is the second axis. The mounting position 403 for fixing one end of the torsion spring is an opening or slot formed on the tab 402, and the other end of the torsion spring is fixed on the water spray assembly 500. The torsion spring 600 is not mounted on the pivot 405 to facilitate installation in a small space.

As shown in fig. 2, in order to engage the pivot 405 with the tab 402, a shaft hole 404 engaged with the pivot 405 is formed in the tab 402. Since the blade is required to have high straightness, the shaft hole 404 into which the blade is fitted is designed to be a long circular hole to compensate for errors in order to eliminate the influence of errors in actual manufacturing, assembly, and the like. If the shaft hole 404 is designed as a circular hole, if the scraper assembly 400 has a dimension error, the scraper assembly 400 may not be installed, and the oblong hole is designed to compensate the dimension error, so that the scraper can be installed smoothly. It should be noted that the oblong holes referred to in the embodiments of the present invention include, but are not limited to, elliptical holes, kidney-shaped holes, and racetrack-shaped holes.

In some embodiments of the present invention, in the first position, the acting force of the plate 401 on the rolling brush 201 is 5-15N. If the acting force of the driving element 600 on the scraper assembly 400 is too large, the acting force of the plate body 401 acting on the roller brush 201 is also increased, the load of the roller brush motor 202 driving the roller brush 201 is increased due to the large acting force, the current and the temperature rise of the motor are influenced, and the effect of extruding the roller brush 201 by the scraper is poor due to the small acting force, the drying time of the whole machine is influenced, and related performances are found based on experimental research. Through continuous verification of the whole machine, the acting force of the plate body 401 on the rolling brush 201 is the optimal selection of 6N.

In some embodiments of the present invention, as shown in fig. 1, a reinforcing rib 406 is disposed on the plate body 401, and the reinforcing rib 406 is a convex hull facing the water spraying assembly 500. Because the scraper and the water spray assembly 500 are both long strips, and the scraper and the water spray assembly 500 are only connected at two ends through the pivot 405, no other connecting structure is arranged in the middle, the scraper and the water spray assembly 500 are easy to deform in the manufacturing, transporting and assembling processes, and the convex hull structure of the reinforcing ribs 406 can be added besides selecting materials with stronger rigidity and increasing the material thickness. The convex hull structure is convex towards the water spray assembly 500, namely the convex hull is convex upwards in the use process, on one hand, the design structure can prevent dirt from being accumulated between the scraper and the water spray plate, if the convex hull is convex towards the direction departing from the water spray assembly 500, a corresponding concave pit is formed on one side towards the water spray assembly 500, and dirt is easily accumulated to cause pollution; on the other hand, the upwardly protruding convex hull may prevent, to some extent, dirt or solids on the upper surface of the squeegee from passing over the convex hull into the interior of the cleaning apparatus.

In some embodiments of the present invention, as shown in fig. 7-10, when the plate body 401 is in the first position, the plate body 401 is disposed obliquely with respect to the horizontal plane, and the height of the plate body 401 gradually decreases along the direction gradually approaching the rolling brush 201. For example, the squeegee may be set 2-10 diagonally downwards in the horizontal direction in the first position. When the water spray assembly 500 sprays water to the roller brush 201 to wet the roller brush 201, liquid generally flows onto the scraper, and the liquid on the scraper can be guided onto the roller brush 201 along the inclination thereof and does not flow back to the base 100 of the cleaning device, as shown by the arrow in fig. 10. Of course, in the second position, the inclination tendency of the plate 401 may also be kept the same as in the first position, i.e. the plate 401 is inclined with respect to the horizontal plane and the height of the plate 401 is gradually reduced along the direction of gradually approaching the roller brush 201, and in this position the scraper can reach the extreme position close to the roller brush 201, and the design is such that the plate 401 can function to guide the water flow to the roller brush 201 in the whole rotation range. The rotation stroke of the plate 401 around the pivot 405 is usually between 3 ° and 8 °, and may be specifically designed according to the structural size and spatial relationship of the actual product, for example, the rotation stroke of the plate 401 around the pivot 405 may be 5.6 °.

It should be noted that in some preferred embodiments, the plate 401 of the scraper assembly 400 is always beyond the water spray assembly 500 during the entire travel between the first position and the second position, so that the liquid dripping from the water spray assembly can be received and guided by the plate 401 regardless of whether the rolling brush 201 is installed or not. At this time, when the plate body is in the second position, one side edge of the plate body for abutting against the rolling brush is located at the position farthest from the water spraying assembly.

In some embodiments of the utility model, the water spray assembly 500 is towards one side of plate body 401 is formed with spacing 502, works as plate body 401 is in during the second position, plate body 401 is in support under the drive power effect of driving piece 600 and press on spacing 502. The limiting strip 502 on the water spraying assembly 500 is positioned on one side of the water spraying assembly 500 close to the rolling brush 201, can be used for limiting the inclination of the first position of the scraper blade, and can play a reasonable limiting role. Spacing 502 has a plurality ofly along the direction evenly distributed of first axis, and a plurality of spacing 502 sets up at interval each other to the elongated structure of adaptation scraper blade. In addition, the limiting strips 502 can enable a necessary gap to be formed between the plate body 401 and the water spraying assembly 500, and the gap cannot be closed under the action of the driving piece 600, namely, the other parts between the water spraying assembly 500 and the plate body 401 except for the limiting strips 502 which are arranged at intervals, are designed to be free of shielding, a gap is formed between every two adjacent limiting strips 502, cleaning is facilitated, and residue accumulation of dirt between the water spraying assembly 500 and a scraper blade is reduced.

In some embodiments of the present invention, as shown in fig. 7 to 13, the water spraying assembly 500 and the rolling brush 201 are both installed on the base 100, and the base 100 below the plate body 401 of the scraper assembly 400 is provided with a sealing strip 700, wherein the sealing strip 700 is a long strip shape, and the extension length thereof is the same as that of the plate body 401. The sealing strip 700 is in interference fit with the lower surface of the plate body 401. Because the utility model discloses plate body 401 among the embodiment is the movable part, consequently must form constantly changeable clearance between plate body 401's below and base 100, sealing strip 700 can form the interference between downside and plate body 401 and seal, can be used for reducing dirty clearance from between plate body 401 below and the base 100 and enter into inside the base 100, sealing strip 700 sets up on scrubbing brush base 100, be located soil pick-up mouth 300 top and the position of neighbouring soil pick-up mouth 300 for dirty can only get into soil pick-up mouth 300 and can not get into scrubbing brush base 100. Preferably, a vertically penetrating drainage hole 701 is formed in the sealing bar 700 at a position corresponding to the dirt suction port 300 of the cleaning device. Although the sealing strip 700 is provided on the base 100 below the plate body 401 of the squeegee assembly 400, the sealing strip 700 is made of an elastic material such as rubber, and a small amount of dirt inevitably enters between the sealing strip 700 and the plate body 401 during use, and therefore, the drainage hole 701 is formed in the sealing strip 700 at a position corresponding to the dirt suction port 300, and as shown in fig. 10 and 13, the dirt above the sealing strip 700 can be brought into the dirt suction port 300 by the negative pressure of the dirt suction port 300. In other embodiments, the drainage holes 701 are semi-open slots, i.e., the drainage holes 701 are open at the side of the sealing strip 700 adjacent to the roller brush.

The scraper assembly 400 is preferably located rearward of the direction of travel of the roller brush 201, and the position where the plate body 401 contacts the roller brush 201 is located at the midpoint or more above the vertical direction of the roller brush 201, so that a better scraping effect can be achieved. At this time, as for the position of the scraper on the water spray assembly 500, the closer the rotation axis of the pivot 405, i.e. the second axis, is to the first axis of the roller brush 201 in the horizontal direction, and the farther away from the first axis of the roller brush 201 in the vertical direction, the smaller the up-down displacement of the plate body 401 in the rotation process around the pivot 405 is, so that as the diameter of the roller brush 201 is continuously reduced, the contact point between the scraper and the roller brush 201 will not be greatly deviated, which is used as a guiding principle for designing the reasonable position of the scraper assembly 400. In some embodiments, the water spray assembly 500 has a sidewall parallel to the tab 402 of the squeegee assembly 400, and the pivot 405 is pivotally attached to the sidewall and offset from a center of the sidewall. Of course the selection of the specific location of the squeegee assembly 400 should also be determined in conjunction with the actual interior space of the product, for example in some examples the horizontal distance of the axis of the pivot 405 from the axis of the roller brush 201 is selected to be 28mm, the vertical distance of the axis of the pivot 405 from the axis of the roller brush 201 is selected to be 19.3mm, and the amount of up and down displacement during rotation of the plate body 401 about the pivot 405 is small.

In some embodiments of the present invention, as shown in fig. 7, 9 and 11, the cleaning device further includes a rolling brush cover 800 and a scraping strip 900, the water spraying assembly 500 is fixed on the rolling brush cover 800, the rolling brush cover 800 is covered and arranged above the rolling brush 201, the scraping strip 900 includes a first portion 901 and a second portion 902 which are connected with each other, the first portion 901 extends downward from the rolling brush cover 800 in an inclined manner to contact with the rolling brush 201, and the second portion 902 extends downward in an inclined manner from one end of the first portion 901 contacting with the rolling brush 201 and gradually gets away from the rolling brush 201.
