Description

cleaning tools

technical field

The present disclosure belongs to the technical field of cleaning equipment, and in particular, relates to a cleaning tool.

Background technique

With the development of modern technology, cleaning tools have been varied, including brooms, mops, floor wipes and vacuum cleaners. Vacuum cleaners are very conventional cleaning tools, but they are very noisy and very uncomfortable. Moreover, the cleaning method of the garbage is only sucking the garbage into the garbage bin.

Brooms, mops, and floor wipes belong to mopping cleaning tools. Generally, they all have a fixed cleaning part, and their cleaning ability depends on the ability of the cleaning part to remove dirt and absorb dirt. Since the cleaning part is polluted once it comes into contact with the dirty floor, the cleaning ability is gradually weakened in the subsequent cleaning process, especially when a large area is continuously cleaned, it cannot be thoroughly cleaned. Therefore, these cleaning products must be rinsed frequently, which is very troublesome.

For Chinese consumers, sweeping and mopping are a must when cleaning the ground, and only sweeping or mopping alone cannot achieve a thorough cleaning of the ground. However, these existing mopping and sweeping machines either require constant washing, or have complex structures and high manufacturing costs, which are prohibitive for ordinary consumers.

Also, existing cleaning tools can either only clean dry trash (brooms or vacuums, etc.) or liquid trash (mops, floor scrubbers, etc.). Its cleaning effect for dry and wet mixed garbage, especially sticky garbage (such as syrup, ketchup, etc.) is either particularly poor or extremely laborious (such as using a rag, which requires multiple washings), which can be said to be helpless.

In addition, the mop or mop-sweeper can have a water tank for water storage. The existing water tank is generally a simple box-like structure, and is fixedly installed on the machine, the water squeezed from the drum may overflow to the ground, and cleaning is inconvenient.

Moreover, an anti-blocking structure is provided, and the filter element can be cleaned by the relative movement of the filter element and the brush assembly, which can increase its filtering capacity and prolong its service life.

Figure 4 shows a preferred sink assembly of the present disclosure. As shown in FIGS. 4 and 5 , the water tank assembly of the present disclosure includes a body 271 and a water press rod 272 . The body 271 is recessed to form a first water tank A1 (a water storage space), and the first water tank A1 is provided with a sewage outlet 271c and a second sewage inlet 271b. The water press rod 272 is rotatable and mounted on the body 271 . The body 271 is also provided with a water retaining rib 271a, which extends along the length direction of the first water tank A1. As shown in FIG. 5 , the water retaining rib 271a has an arc-shaped surface, and a part of the outer circumferential surface of the water-pressing rod 272 is attached to the arc-shaped surface. The second sewage inlet 271b is provided on the water retaining rib 271a, and the sewage enters the first water tank A1 through the second sewage inlet 271b.

Sewage contains scum, sludge or other sticky substances. After entering the cleaning tool, the water pipe is easy to be blocked. Therefore, a filter screen 274 may be provided at the sewage outlet 271c. At this time, the sewage from the extrusion first passes through the filter screen 274, and is filtered and then discharged. In this case, the side housing of the cleaning tool can be designed to be relatively thin. The pore size of the filter screen 274 may be 0.3˜0.7 mm, preferably 0.5 mm.

The filter screen 274 is also easily blocked. Therefore, a first roller brush 275 can be correspondingly disposed above the filter screen 274 for cleaning the garbage on the filter screen 274 . The first roller brush 275 is rotatable and can be driven by a power device to rotate. In the embodiment shown in FIG. 4 , the first roller brush 275 is driven by the power device of other parts of the cleaning tool, and the sink assembly includes a transmission gear 273a, a bearing 273b and a connecting piece 273c installed in the body. The power unit of other parts of the cleaning tool drives the first roller brush 275 to rotate through the transmission gear 273a, the bearing 273b and the connecting piece 273c.

As shown in FIG. 5 , after the water tank assembly is installed to the cleaning tool, the water press rod 272 interferes with the sponge layer of the drum 111 , and the water in the sponge layer is squeezed out by the water press rod 272 . When the drum 111 is also detachable, the squeezed water easily leaks from both ends of the drum. Therefore, in a preferred embodiment of the present disclosure, the body 271 is further provided with a water guide 271d. When the water tank assembly is installed to the cleaning tool, the water guide 271d interferes with the sponge layer of the drum 111 of the cleaning tool, which is equivalent to statically pressing the drum 111 . The function of the water guide member 271d is to guide the water at the side of the drum 111 to the middle, so as to prevent water leakage at both ends. The upper end of the water guide member 271d shown in FIGS. 4 and 5 is large and the lower end is small, which looks like a horn from the side. Of course, the water guide member 271d is not limited to this structure, as long as the corresponding function can be achieved. As shown in FIG. 4( c ), there are preferably two water guide members 271d, which are respectively disposed on both sides of the water press rod 272 (ie, above the two sides of the drum 111).

In the present disclosure, one end of the bottom surface of the first water tank A1 is high, and one end (sewage outlet end) is low, and has a slope. When there is water in the first water tank A1, the water can flow directly to the sewage outlet under the action of its own weight.

The water tank assembly of the present disclosure has a first water tank, which has the function of buffering sewage. Moreover, the water tank assembly is provided with a rotatable water pressing rod, which rotates relative to the drum when it is installed on the cleaning tool, which can more easily squeeze the sewage out of the sponge layer of the drum. In addition, the sink assembly is detachably mounted on the cleaning tool for frequent cleaning.

6 to 12 illustrate a cleaning tool according to a preferred embodiment of the present disclosure.

The cleaning tool of the present disclosure includes a cleaning module and a water circulation module. Wherein, the cleaning module includes a drum 111 . The drum 111 has at least two layers, and the outermost layer is a sponge layer, which is used for absorbing water and cleaning garbage. The innermost layer is the support layer, which is made of hard material. The driving motor can be sleeved in the drum 111, which can save space and reduce the volume of the cleaning tool.

The water circulation module includes a water tank 260 and a sump assembly 270 . The specific structures of the water tank 260 and the water tank assembly 270 are shown in FIGS. 1 to 5 , which will not be repeated here. The water retaining rib 271A, the water pressing rod 272 and the drum 111 together form the second water tank A2 (water accommodating space). The first water tank A1 and the second water tank A2 are connected through the second sewage inlet 271b. The water pressing rod 272 is parallel to the drum 111 and interferes with the sponge layer of the drum 111 . The water tank 260 is connected to the first water tank A1.

The water tank 260 can be installed on the cleaning head of the cleaning tool, or can be installed on the handle portion (as shown in FIG. 6 ), and the specific position can be determined according to needs.

As shown in FIGS. 7 and 8 , the cleaning head of the cleaning tool of the present disclosure is equipped with a drum 111 , a second roller brush 131 , a trash box 141 , and a water tank assembly 270 . The side housing is provided with a roller quick release button 536a, a roller quick release buckle 536b, a roller brush quick release button 537a, a roller brush quick release buckle 537b, and a water tank roller brush quick release 538. The drum 111 is detachably mounted on the housing through the drum quick release button 536a and the drum quick release buckle 536b. The second roller brush 131 is detachably mounted on the housing through the roller brush quick release button 537a and the roller brush quick release buckle 537b. The sink assembly 270 is removably mounted on the housing via the sink roller quick release 538 .

As shown in Figure 8, the cleaning module is also provided with a shovel, one end of the shovel is in contact with the ground, and has an arc-shaped working surface (point a to point b). A garbage channel is formed between the arc-shaped working surface and the outer circumferential surface of the drum 111 . The second roller brush 131 is located between the drum 111 and the garbage box 141 , and is used for cleaning the dry garbage on the surface of the drum 111 .

One end of the drum 111 is provided with a buckle, so that it can be easily disassembled from the casing 500 . The motor is installed inside the drum 111, and the rotating shaft is installed on the casing. The drive motor drives the internal hard material to rotate around its axis through the drum transmission mechanism, and drives the sponge layer to rotate, so that the surface of the sponge layer makes a circular motion.

When the drum 111 rolls over the ground, the dry garbage particles on the ground press and deform the sponge layer, and the sponge layer wraps the dry garbage particles through deformation, so that the dry garbage particles are separated from the ground and rotate together with the drum 111 . When turning to the position of the blade a, the particles of dry garbage leave the ground, are squeezed by the blade, and continue to rotate together with the drum 111 . When turning over the shovel and turning to b, due to the loss of the pressure of the shovel, the sponge layer recovers and deforms, and releases the dry garbage particles wrapped by it. The bristles of the second rolling brush 131 are in contact with the sponge layer, and the moving directions of the second rolling brush 131 and the roller 111 are opposite. The released or brushed rubbish enters the rubbish box 141 along the movement track of the second roller brush 131 .

As shown in FIGS. 9 and 10 , the upper cover 510 of the present disclosure includes a purified water inlet 512 , a water spout 513 , a spring column 514 , a housing switch 515 , a locking tongue 516 and a water pipe 517 .

In the upper cover 510 shown in FIGS. 9 and 10 , there are two water spray ports 513 , which are symmetrically arranged on the upper cover 510 . In other embodiments of the present disclosure, the water spout 513 may be arranged in one or even one or more rows, as required. The upper cover 510 shown in FIGS. 9 and 10 is detachable, and is detachably connected to the cleaning head through a spring column 514 , a housing switch 515 , and a locking tongue 516 .

A water pipe 517 is connected between the purified water inlet 512 and the water spray port 513 .

One end of the first water tank A1 of the present disclosure is provided with a sewage outlet 271c, and the sewage outlet 271c is connected to the first sewage inlet 261a of the water tank 260 . The sewage can be sucked from the first water tank A1 into the water tank 260 by the power device.

Optionally, sewage can be sucked from the first water tank A1 into the water tank 260 by a water pump. At this time, the water pump is respectively connected to the sewage outlet 271c and the first sewage inlet 261a through the sewage pipe.

The present disclosure includes two filtering devices, a filter screen and a filter element, that is, the cleaning tool of the present disclosure can perform two-stage filtering on sewage. The water squeezed from the drum first enters the filter screen to filter out the relatively large garbage, then enters the water tank, and then filters out the small garbage through the filter element. After two-stage filtration, the sewage can be turned into relatively clean purified water, which can be reused for cleaning the drum, which greatly saves water resources, and reduces the number of times the user needs to replace the water, which is convenient for use.

When the water tank 260 is mounted to the handle portion as shown, the purified water discharged from the water tank 260 may flow to the cleaning head by the water pump or by its own weight. If a water pump is used, the water pump is connected to the purified water outlet 261b and the water spray port 513 respectively through the purified water pipe.

In the embodiment shown in FIG. 11, both sewage and purified water are sucked by a water pump. A first water pump 217 and a second water pump 233 are provided. The first water pump 217 is used for pumping sewage, and the second water pump 233 is used for pumping purified water. In Fig. 11, L refers to the left side of the cleaning head, and R refers to the right side of the cleaning head.

The cleaning tools of the present disclosure may also include a disinfection assembly. Among them, the disinfection assembly may include an ozone generator 222a (as shown in FIG. 11 ). The ozone generator 222a passes the ozone generated by the ozone generator 222a into the transfer water tank 223 through an air pump and an air pipe (not shown in the figure), so as to sterilize and sterilize the purified water and prevent the water from becoming smelly. In addition, because the water has ozone, it can also disinfect and sterilize the ground.

In the embodiment shown in FIG. 6 , the ozone generator 222a is disposed on the handle 303, and in other embodiments of the present disclosure, the sterilizing component may also be disposed in other parts, depending on the requirements. As shown in FIG. 11 , the transfer water tank 233 is provided with an ozone inlet 233b and a pressure balance port 223c. The ozone generated by the ozone generator 222a enters the transfer water tank 223 through the ozone inlet 233b.

Moreover, the sterilizing component can also be other sterilizing devices such as UV lamps, and the ozone generator is only a preferred embodiment thereof.

An adjustment knob may also be provided on the handle of the cleaning tool of the present disclosure. The adjustment knob can adjust the water output speed. When the ground is very dry, you can increase the amount of water to make the ground wet; when there is water on the ground, you can adjust it to a smaller value or no water, and let the cleaning tool absorb the water on the ground. .

As shown in FIG. 6 , an observation window 223 a may be provided in the transfer water tank 223 . It is convenient for the user to observe the state of the water in the transfer water tank 223 and decide whether to inject clean water.

The cleaning tool of the present disclosure may have wheels mounted on the cleaning head. The embodiment shown in Figure 6 has two sets of rollers (front 151 and rear 152). There are two front wheels 151 and two rear wheels 152 respectively, wherein the rear wheels 152 can be connected with a power device (motor).

In addition, in the present disclosure, if the side shells corresponding to the drum 111 are relatively thick, the ground corresponding to the shells on both sides of the drum 111 must not be cleaned by the drum 111 , thus causing a cleaning blind area. In order to clean this blind spot, at least one side brush can be respectively provided on the side of the drum 111 . Two side brushes may be symmetrically disposed on the casings on both sides of the drum 111 .

The housing at the end (front side) of the cleaning tool of the present disclosure on which the drum 111 is installed may also be provided with an anti-collision strip (not shown in the figure) to avoid collision and damage to the housing during the cleaning of the ground. A searchlight (not shown in the figure) can also be installed, which can help the user to better clean up when cleaning a relatively dark place such as the bottom of the bed.

FIG. 12 is a schematic diagram of a waterway according to an embodiment of the disclosure. The sewage is squeezed from the drum and enters the water tank for filtration. After filtering, it is pumped to the transfer water tank by the pump, and ozone is added to the transfer water tank, and then reused by the pump to the drum to clean the drum. In this way, the water cycle is realized.

In some embodiments of the present disclosure, the user adds clean water to the water tank 260, holds the hand-held portion, turns on the switch, and activates the device. The clean water is sucked to the water spray port 513 along the purified water outlet 261b and then sprayed on the drum 111 . The user pushes the cleaning tool to move back and forth. Before touching the ground, the sponge layer on the drum 111 is slightly wet (not saturated with water), and after touching the ground, the slightly wet sponge layer absorbs the liquid garbage on the ground while cleaning the ground. of solid waste.

With the cooperation of the blade 112 , the large solid waste carried by the drum 111 reaches point b through the gap between it and the blade 112 , and then enters the waste box 141 along the movement track of the second roller brush 131 . The small particle garbage is embedded on the sponge layer, and with the movement of the drum 111 , reaches the position b, is brushed by the bristles of the second roller brush 131 , and enters the garbage box 141 along the movement track of the second roller brush 131 .

The drum 111 continues to roll and reaches the water press rod 272 . The water pressing rod 272 squeezes the sponge layer to squeeze out the sewage in the sponge layer. The water pressing rod 272 always interferes with the sponge layer of the drum 111 and keeps squeezing the sponge layer, which is equivalent to the water pressing rod 272 constantly wringing out the drum 111 during use, and then spraying clean water. That is, during use, the drum 111 is always being cleaned. The extruded sewage flows into the first water tank A1 through the second water tank A2, and then enters the water tank 260 through the sewage pipe. On the drum 111, the drum 111 is cleaned. In this continuous cycle, the ground is cleaned.

At the same time, the ozone generator 222a continuously sprays ozone into the transfer water tank 233, thereby realizing the simultaneous disinfection and sterilization of the water in the water tank A and the ground.

When using the cleaning tool of the present disclosure to clean the ketchup on the ground, the user first adds clean water to the water tank 260, holds the hand-held portion, turns on the switch, and starts the device. The clean water is sucked to the water spray port 513 along the purified water outlet 261b and then sprayed on the drum 111 . The user pushes the cleaning tool to move back and forth, and the drum 111 moves accordingly. The drum 111 is in contact with the ground, and the ketchup adheres to the sponge layer of the drum 111 and partially penetrates into the sponge layer of the drum 111 . The roller 111 continues to rotate and reaches point b, where the sponge layer is in contact with the second roller brush 131 . The ketchup cannot be brushed off by the second rolling brush 131, and still adheres to the sponge layer at point b.

The drum 111 continues to roll and reaches the water press rod 272 . The water pressing rod 272 squeezes the sponge layer to squeeze out the sewage in the sponge layer. There is always water in the second water tank A2. Under the action of the water, the tomato paste is released from the sponge layer, enters the second water tank A2, and is filtered out through the filter screen 274 and the filter element 263. Since then, the ketchup has been cleaned up. The filtered purified water is then sprayed onto the drum 111 through the purified water pipe under the action of the water pump to clean the drum 111 .
