Technical Field

The utility model belongs to the technical field of cleaning device, specifically, relate to a basin and automatically cleaning are dragged and are swept machine.

Background

With the development of modern technology, floor cleaning tools have been diversified, including brooms, mops, floor wipers, dust collectors, and the like. The cleaner is a very conventional floor cleaning tool, but the cleaner is very noisy and uncomfortable. And the garbage is cleaned only by sucking the garbage into the garbage box.

Brooms, mops and floor wipers are cleaning tools of the mop type, which generally have a fixed cleaning part, the cleaning capacity of which is determined by the dirt removing and absorbing capacity of the cleaning part. Since the cleaning portion is contaminated as soon as it comes into contact with the soiled floor, the cleaning power is gradually reduced during the subsequent cleaning process, and complete cleaning cannot be achieved, particularly when a large area is continuously swept. Therefore, the cleaning articles must be washed frequently, which is very troublesome.

For Chinese consumers, sweeping and mopping are necessary when cleaning the floor, and the floor cannot be thoroughly cleaned only by sweeping or mopping. However, these existing mopping and sweeping all-in-one machines either need to be washed continuously, or have complex structures and high manufacturing cost, so that ordinary consumers are prohibited.

Furthermore, existing floor cleaning tools can only clean dry waste (brooms, cleaners, etc.) or can only be used to clean liquid waste (mops, floor mops, etc.). It is said to be unwarranted by the hand that the cleaning of dry and wet mixed waste, in particular sticky waste (such as syrup, ketchup, etc.), is either particularly poor or very laborious (e.g. with rags, requiring multiple washes).

In addition, the mopping machine or the mopping and sweeping all-in-one machine can be provided with a water tank for storing water. The existing water tanks are generally of a simple box-like structure and are fixedly mounted on the machine, and water squeezed out of the drum may overflow to the ground and be inconvenient to clean.

The specific meaning of the above terms in the present disclosure can be understood in specific instances by those of ordinary skill in the art.

The self-cleaning mopping machine disclosed by the invention is used for cleaning floors, particularly smooth and flat small-area floors such as household and kitchen floors. The self-cleaning mopping machine disclosed by the invention is particularly suitable for cleaning mixed garbage mixed with dry garbage, wet garbage and sticky substances such as noodles, porridge, tomato sauce and the like.

Fig. 1-10 illustrate a preferred self-cleaning sweeper of the present disclosure.

The self-cleaning mopping machine provided by the present disclosure may include: a housing 500, a cleaning module, and a water circulation module. Wherein, the cleaning module comprises a garbage box 141, a roller 111, a shovel bar 112, a water pressing bar 122 and a scraper bar assembly 133 which are respectively installed on the housing 500. Wherein, the outside of the roller 111 is a sponge layer 111 b. One end of the shovel bar 112 is in contact with the ground, and the other end is located above the trash box 141. The shoveling bars 112 have arc-shaped working surfaces with a uniform gap at a distance from the outer circumferential surface of the drum 111, and the gap forms a trash passage through which solid trash swept from the ground enters the trash box 141.

The drum 111 has at least two layers, and the outermost layer is a sponge layer 111b for absorbing water and cleaning garbage. The innermost layer is a supporting layer and is made of hard materials. The driving motor can be sleeved in the roller 111, so that the space can be saved, and the size of the ground cleaning tool can be reduced.

The roller 111 may be detachably provided with a snap at one end, thereby facilitating detachment from the housing 500. The motor is installed inside the drum 111, and the rotation shaft is installed on the housing 500. The driving motor drives the hard material inside the roller transmission mechanism to rotate around the axis of the hard material, so that the sponge layer 111b is driven to rotate, and the surface of the sponge layer 111b makes circular motion.

When the roller 111 rolls on the ground, the sponge layer 111b is pressed and deformed by the particles of the dry garbage on the ground, and the particles of the dry garbage are wrapped by the sponge layer 111b through deformation, so that the particles of the dry garbage are separated from the ground and rotate together with the roller 111. When turned to the position of the shoveling bars 112, the particles of the dry waste leave the ground, are squeezed by the shoveling bars 112, and continue to rotate with the drum 111. When the garbage box is rotated to the entrance of the garbage box 141 after passing the shovel strip 112, the sponge layer 111b is restored to deform due to the loss of the compression of the shovel strip 112, and the dry garbage particles wrapped by the sponge layer are released and are ejected into the garbage box 141.

The water pressure bar 122 interferes with the sponge layer 111b of the drum 111, and the water pressure bar 122 is used for squeezing the sponge layer 111b, so that water in the sponge layer 111b is squeezed out. Optionally, the interference amount of the water pressing bar 122 and the roller 111 is 2-4 mm.

The wiper strip assembly 133 includes a friction end 133a and a drainage end 133 b. As shown in fig. 3, both the friction end 133a and the drainage end 133b interfere with the drum 111. Optionally, the interference amount is 1-2 mm, preferably 1.5 mm.

The garbage carried by the roller 111 can enter the garbage box 141 under the action of the self-weight, but small solid garbage or viscous garbage is difficult to separate from the sponge layer of the roller 111, and if the separation is not performed first, a large amount of small garbage can be carried in the sewage extruded from the roller 111. The frictional end 133a of the wiper strip assembly 133 is embedded in the sponge layer 111b above the garbage box 141 to separate the garbage from the sponge layer 111b of the drum 111. When the drum 111 rotates, the friction end 133a and the sponge layer 111b of the drum 111 rub against each other, thereby brushing the garbage from the drum 111 into the garbage box 141.

The drainage end 133b serves to drain the water pressed down from the drum 111 into the water tank a. The drainage end 133b of the self-cleaning device shown in fig. 1-10 is embedded in the sponge layer 111b, which is configured to minimize the flow of water squeezed out along the roller 111 to the floor or other components of the floor cleaning tool. Optionally, the drainage end 133b of the wiper strip assembly 133 may also be attached to the sponge layer 111b to provide a corresponding drainage function, but the drainage end 133b is made of a flexible rubber material to be attached to the roller 111 better.

As shown in fig. 3, the water tank a of the present embodiment is formed by the drum 111, the water pressing bar 122, the bar unit 133, and the housing 500. The housing 500 is provided with a water tank inlet and a water tank outlet, and clean water and/or purified water enters the water tank a from the water tank inlet and sewage flows out of the water tank a from the water tank outlet.

The water inlet and outlet of the water tank may be respectively disposed at both ends of the water tank (as shown in fig. 4). The direction of the arrows in fig. 4 is the direction of flow of water in the cleaning head, with the tank inlet on the right and the tank outlet on the left. Clean water or purified water enters from the water inlet, sewage after the roller 111 is cleaned flows out from the water outlet of the water tank, water enters from one end and exits from the other end to form dynamic water flow, and therefore the roller 111 is cleaned. The viscous trash adhered to the sponge layer 111b of the drum 111 is released from the sponge layer 11b into the water tub a at the water tub a by the water. The top end of the scraping strip assembly can be inclined, one end of the water inlet of the water tank is higher than that of the water outlet, and water flows in the water tank A by means of self weight at the moment. The position of the water inlet of the water tank can be the same as that of the water outlet, and at the moment, the water in the water tank A can be sucked out of the water outlet under the action of a reliable power device (such as a water pump or an air pump).

Water inlets may be provided at both ends of the water tank A, and at this time, water flows from both ends to the middle of the water tank A from both water inlets. A water nozzle may be provided on the housing 500, which is located at the upper end of the middle of the basin a and is connected to the sewage pipe. Under the action of the power device, sewage is pumped out from the water tank A through the water nozzle and enters the sewage pipe.

Clean water or purified water may also be sprayed into the basin a from the upper end of the basin a. At this time, at least one row of water spray nozzles is arranged on the upper shell. The clean water or purified water is sprayed into the water tub a from the water spray port, washes the drum 111, and is then sucked away from the water tub a by the self-weight or power device.

And more water can be injected, and the water can flow to the sewage outlet by virtue of the tension of the water.

In addition, a spiral protrusion may be provided on the drum 111, and the protrusion may serve to accelerate the water flow. The spiral protrusion extends from one end to the other end of the drum 111 to guide water from the water inlet to the water outlet of the water tank a. The spiral protrusion can also be two sections, and the spiral protrusion extends from two ends to the middle, so that water on two sides is guided to the middle.

The water circulation module of the present disclosure includes a water tank 250, a sewage pipe (not shown) and a purified water pipe (not shown) which are mounted on the housing 500, respectively. As shown in fig. 1, 2, 7, and 8, the water tank 250 is an integrated water tank that is detachably mounted on the cleaning head. The water tank 250 is provided with an ejecting switch 253 and a latch 256, and the ejecting switch 253, the latch 256 and an elastic needle 531 on the housing 500 are matched with each other, so that the water tank 250 can be mounted or dismounted.

The water tank 250 includes a sewage box 251, a filter box 254, and a purified water box 253. Wherein the sewage box 251 includes a sewage inlet 251a, and the purified water box 253 includes a purified water outlet 252 a. The inlet 251a and outlet 252a are provided with one-way valves (as shown in figure 9), the inlet 251a being connected to a sewage port spike 532 on the housing and the outlet 252a being connected to a purified water port spike 533 on the housing, to ensure that water in the tank 250 does not overflow from the inlet 251a or outlet 252a when the tank 250 is removed from the cleaner head.

The sewage pipe is connected to the water outlet of the water tank and the sewage inlet 251a of the sewage box 251, respectively. The purified water pipe is connected to the water inlet of the water tank and the purified water outlet 252a of the purified water cartridge 252, respectively.

A filter cartridge 254 is installed between the sewage cartridge 251 and the purified water cartridge 252. The filter cartridge 254 is used to filter large-sized garbage in the sewage. As shown in fig. 8, the cartridge 254 is detachably mounted to the water tank 250. The water tank 250 is provided with a water tank cover 255 corresponding to the filter cartridge 254 for taking and putting the filter cartridge 254. The cartridge 254 is also provided with a cartridge top cap 254 a.

The filter cartridge shown in fig. 7 to 9 is closed, a power device is provided at the outlet end of the purified water, and under the action of the power device, the purified water is pumped out of the water tank 250 from the purified water outlet 252a, and the water tank 250 forms a negative pressure, so that the sewage is pumped into the water tank 250 from the sewage inlet 251a, and then is filtered by the filter cartridge 254, and enters the purified water cartridge 252. So that the sewage is filtered repeatedly.

The power device arranged on the purified water box side is preferably a water pump. The water pump may include a first water pump connected to the purified water pipe, wherein the first water pump is connected to the purified water outlet 252a of the purified water cartridge 252 and the water inlet of the water tank through the purified water pipe, respectively.

A power unit may be provided on the sewage box 251 side. The power means may comprise a water pump or an air pump. When the second water pump is used, the second water pump is respectively connected with the sewage inlet 251a of the sewage box 251 and the water outlet of the water tank through the sewage pipe.

If the vacuum negative pressure principle is adopted to suck the sewage into the sewage box 251, the power device is an air pump, and an exhaust pipe is correspondingly arranged. Under this kind of condition, sewage can not contact with the motor, can not cause the influence to the motor, the long-life of motor. An air pumping opening is further formed in the sewage box 251, one end of the air pumping pipe is connected with the air pumping opening, and the other end of the air pumping pipe is connected with the first air pump. In operation, the first air pump draws air from the interior of the waste box 251 to form a negative pressure, and the end of the waste pipe 212 for drawing waste water draws waste water from the sink a into the waste box 251.

An air outlet is arranged on the first air pump. When the sewage box 251 is full, sewage enters the air pump and flows out from the air outlet, and the sewage pipe can further comprise an overflow pipe in order to avoid the sewage flowing everywhere. One end of the overflow pipe is connected with the air outlet of the first air pump, and the other end of the overflow pipe can be aligned with the roller 111, so that the sewage can be directly discharged onto the roller 111.

As shown in FIGS. 1, 2, and 10, the self-cleaning sweeper of the present disclosure may also include a sanitizing assembly 222. The sterilization assembly 222 may include an ozone generator 222a, a second air pump 222b, and an air tube (not shown). Wherein, the second air pump 222b is connected with the ozone generator 222a and the water tank A through an air pipe respectively. The ozone generated by the ozone generator 222a enters the water tank a through the air pipe to sterilize and disinfect the water in the water tank a and prevent the water from becoming odorous. In addition, the water in the water tank A is provided with ozone, so that the ground can be disinfected and sterilized.

While the disinfecting assembly 222 is also disposed on the handle 303 in the embodiment shown in fig. 1, 2 and 10, in other embodiments of the present disclosure, the disinfecting assembly 222 may be disposed at other locations as desired.

Also, the sterilization assembly 222 could be other sterilization devices such as a UV lamp, with an ozone generator being only a preferred embodiment.

As shown in FIG. 1, the handle of the self-cleaning mop of the present disclosure may further include an adjusting knob 306 and a push switch 307. The adjusting knob 306 can adjust the water outlet speed, and when the ground is very dry, the water quantity can be increased, so that the ground is wet; when water is on the ground, the water can be reduced or not discharged, and the self-cleaning sweeping device can suck the water on the ground. The push switch 307 is a general circuit switch, and is pressed to start the self-cleaning sweeping device.

As shown in fig. 3, a water tank observation window 511 may be provided on the case 500 corresponding to the upper end of the water tank a. The user can conveniently observe the water tank A to determine whether to inject clear water.

The cleaning head of the self-cleaning mopping machine can be provided with a roller. In the embodiment shown in fig. 5, there are two sets of rollers (front wheel 151 and rear wheel 152). Two front wheels 151 and two rear wheels 152 are provided, wherein the rear wheels 152 can be connected to a power unit (motor).

In addition, in the present disclosure, if the side casing corresponding to the drum 111 is relatively thick, the floor corresponding to the casings on both sides of the drum 111 cannot be cleaned by the drum 111 without fail, and thus a cleaning blind area is caused. In order to clean the blind area, at least one side brush 190 (as shown in fig. 5) may be provided at each side of the drum 111.

In some embodiments of the present disclosure, the user adds fresh water to the water tank 250, holds the handle, opens the switch 307, and activates the self-cleaning sweeper. The clean water is sucked along the purified water outlet 252a to the water inlet of the tub a and then the drum 111 is supplied with water. The user pushes the floor cleaning tool forward and backward and the drum 111 moves accordingly. The sponge layer on the drum 111 is slightly wet (unsaturated in water absorption) before contacting the ground, and after contacting the ground, the slightly wet sponge layer absorbs the liquid garbage on the ground and cleans the solid garbage on the ground. The sticky garbage adheres to the sponge layer.

In cooperation with the shoveling bars 112, the large solid garbage carried up by the rollers 111 reaches the garbage box 141 through the gap between the shoveling bars 112 and the garbage box. The small particle garbage and/or the sticky garbage are embedded or adhered on the sponge layer and reach the friction end 133a of the scraping strip assembly 133 along with the movement of the roller 111, and under the action of the friction end 133a, the small particle garbage embedded or adhered on the sponge layer is brushed down and enters the garbage box 141 under the action of self weight.

The drum 111 continues to roll to the pumping bar 122. The pressurized water barrier strip 122 extrudes the sponge layer to extrude the sewage in the sponge layer. The lower end of the water pressing bar 122 continuously presses the sponge layer of the roller 111, which is equivalent to that the water pressing bar 122 continuously cleans the roller 111 during the use of the floor cleaning tool. The extruded sewage is drained to the sink a through the drainage end 133 b. At the water tank a, the viscous trash is released from the sponge layer 111b of the drum 111 by the water and enters the sewage. The sewage enters the sewage box 251 of the water tank 250 through the sewage pipe, is filtered by the filter box 254, and then enters the purified water tank 252. Then the water is recycled to the water tank A through the purified water pipe under the action of a power device (a water pump) to clean the roller 111. The above steps are continuously circulated, and the ground is cleaned.

Meanwhile, the ozone generator 222a continuously sprays ozone into the water tank a, thereby simultaneously sterilizing and disinfecting the water in the water tank a and the ground.

The housing at the end of the self-cleaning mopping machine provided with the roller 111 can be provided with an anti-collision strip (not shown in the figure) to avoid collision and damage to the housing 500 during the floor cleaning process. A searchlight (not shown) may also be provided to assist the user in cleaning when it is relatively dark, such as a bed bottom.

Fig. 11 to 13 show another form of the disclosed sink a, which is an integrated structure, not formed by the drum 111, the water pressing bar 122, the wiper strip assembly 133 and the housing 500, and detachably mounted to the housing 500. Of course, the water tank a may be fixedly mounted on the housing 500, and may be provided according to actual conditions.

As shown in FIGS. 11 to 13, the water tank A includes a water passage A-1, a purified water inlet A-2, a sewage outlet A-3, a sewage inlet A-4, and a wiper strip assembly A-5. Wherein, the purified water inlet A-2 and the sewage outlet A-3 are respectively arranged at two ends of the water tank A. The scraping strip assembly A-5 is arranged on the bottom surface of the water tank A.

The wiper strip assembly a-5 in this embodiment is similar to the wiper strip assembly 133 shown in fig. 1-10, and includes a friction end and a flow guiding end extending from one end of the water channel a-1 to the other end of the water channel a-1. Both the friction end and the drainage end interfere with the sponge layer 111b of the drum 111. Optionally, the interference amount is about 1-2 mm, preferably 1.5 mm.

The sewage inlet A-4 is formed by a gap between the drainage end and the water channel A-1.

The frictional end of the wiper strip assembly a-5 interferes with the sponge layer 111b, and is positioned above the garbage box 141, so that most of the garbage to be embedded and/or adhered on the sponge layer 111b of the drum 111 can be separated from the sponge layer 111 b. When the drum 111 rotates, the friction end and the sponge layer 111b of the drum 111 rub against each other, thereby brushing the garbage from the drum 111 into the garbage box 141.

The drainage end is used for draining the water squeezed from the drum 111 into the water passage a-1 of the water tank a. The drainage end interferes with the sponge layer 111b so that the arrangement is such as to minimise the flow of water squeezed out along the roller 111 to the place or other components of the floor cleaning tool. Similarly, the drainage end of the scraper bar assembly A-5 can be attached to the sponge layer 111b and can also perform a corresponding drainage function.

Alternatively, the wiper strip assembly A-5 is made of a flexible material (e.g., rubber) and the sealing effect is achieved because the flexible material and the sponge layer are soft and form a soft-to-soft effect.

In the embodiment shown in fig. 11-13, the water squeezed from the sponge layer 111b of the roller 111 by the water pressure bar 122 is guided by the flow guiding end of the bar scraping assembly a-5, enters the water channel a-1 through the sewage inlet a-4, and flows along the water channel a-1 to the sewage outlet a-2. Clean water or purified water enters the water channel A-1 through the purified water inlet A-2, and when the water pressure of the clean water or the purified water is higher or the water flow is larger, the clean water can reach the roller 111 from the sewage inlet A-4 along the drainage end of the scraping strip assembly A-5, so that the roller 111 is cleaned. Since the sewage enters the water passage a-1 through the sewage inlet a-4, the flow direction of the clean water or the purified water is opposite to that of the sewage, which causes the water to be agitated, corresponding to the washing of the drum 111.

When the sink A is detachable, it can be snapped onto the housing 500 by a snap. And a purified water inlet a-2 thereof is connected to the purified water outlet 252a of the water tank 250. The sewage outlet a-3 is connected to the sewage inlet 251a of the water tank 250.

The rest is similar to the embodiment of FIGS. 1 to 10, and will not be described herein again.

In the disclosure, water can be circulated for multiple times, and garbage (dust) can be cleaned smoothly, and the disclosure refers to the technology as water-dust circulation cleaning technology.

The self-cleaning of the roller can be realized by utilizing the water-dust circulation cleaning technology, the sweeping, the dragging, the washing and the twisting are combined together, the user is greatly facilitated, the very good cleaning effect can be realized, and particularly, the self-cleaning roller has a very good cleaning effect on viscous garbage which is very difficult to treat, such as tomato sauce, chocolate sauce and the like.

It should be understood that the above examples are only for clearly illustrating the present disclosure, and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the invention as herein taught are within the scope of the present disclosure.
