Description

[0001] This application is a divisional application of Chinese patent application number 202010073660.8 and invention name “Cleaning Tool”, the contents of which are incorporated herein by reference. Technical Field

[0002] The present invention belongs to the technical field of cleaning equipment, and in particular relates to a cleaning head. Background Art

[0003] With the development of modern technology, there are many cleaning tools, including brooms, mops, floor wipes and vacuum cleaners. Vacuum cleaners are very common cleaning tools, but they make a lot of noise, which makes people very uncomfortable. And the way they clean garbage is just to suck the garbage into a garbage box.

[0004] Brooms, mops, and floor wipes are sweeping cleaning tools, which generally have a fixed cleaning part. Their cleaning ability is determined by the dirt removal and dirt absorption ability of the cleaning part. Since the cleaning part is contaminated once it comes into contact with the dirty ground, the cleaning ability is gradually weakened in the subsequent cleaning process, especially when cleaning a large area continuously, it is impossible to clean thoroughly. Therefore, these cleaning products must be rinsed frequently, which is very troublesome.

[0005] For Chinese consumers, sweeping and mopping are both necessary for cleaning the floor. Sweeping or mopping alone cannot achieve a thorough cleaning of the floor. However, these existing sweeping and mopping machines either require constant washing or have a complex structure and are very expensive, which makes ordinary consumers reluctant to buy them.

[0006] Moreover, existing cleaning tools can only clean dry garbage (brooms or vacuum cleaners, etc.) or can only be used to clean liquid garbage (mops, floor wipes, etc.). For mixed dry and wet garbage, especially sticky garbage (such as syrup, ketchup, etc.), the cleaning effect is either very poor or very laborious (for example, using a rag, which needs to be washed many times), which can be said to be helpless.

[0007] In addition, the mopping machine or the mopping and sweeping machine may be provided with a water tank for storing water. The existing water tank is generally a simple box-shaped structure and is fixedly mounted on the machine. The water squeezed out from the drum may overflow onto the ground, and it is also inconvenient to clean. Summary of the invention

[0068] Reference to "embodiments" in this disclosure means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the disclosure. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this disclosure may be combined with other embodiments.

[0069] As shown in FIGS. 1 to 3 , the water tank provided by the present disclosure includes a water tank body 261 , a driving mechanism 262 , a filter element 263 , a brush assembly 264 and a sealing assembly.

[0070] The water tank body 261 is provided with a receiving chamber for receiving water. The filter element 263 is installed in the receiving chamber, and the filter element 263 divides the receiving chamber into a sewage receiving chamber (outside the filter element 263) and a purified water receiving chamber (inside the filter element 263) that are independent of each other. The sewage receiving chamber is provided with a first sewage inlet 261a, and the purified water receiving chamber is provided with a purified water outlet 261b. Sewage enters the sewage receiving chamber from the first sewage inlet 261a, is filtered by the filter element 263, enters the purified water receiving chamber, and then flows out of the water tank through the purified water outlet 261b.

[0071] In the embodiment shown in Figures 1 to 3, the filter element 263 is detachably installed in the accommodating cavity. The water tank is provided with a rear cover 267 for taking out and placing the filter element 263. In the present disclosure, the material of the filter element 263 is not limited, and can be made of materials such as stainless steel, ceramics or filter cotton, and the aperture of the filter hole can be set according to actual needs.

[0072] After the filter element 263 has filtered sewage for a period of time, the surface is easily clogged. In order to clean the blockage, the water tank of the present disclosure also includes a brush assembly, which is also installed in the accommodating cavity. In the present disclosure, the brush assembly is used to clean the filter element.

[0073] In order to better prevent blocking, the filter element 263 and the brush assembly need to rotate relative to each other, so the water tank of the present disclosure is also provided with a driving mechanism. The driving mechanism is installed in the body and is used to drive the filter element 263 and / or the brush assembly to rotate.

[0074] In the embodiment shown in FIGS. 1 to 3 , the brush assembly includes a first brush 264a. The first brush 264a is installed outside the filter element 263, and the bristles of the first brush 264a are in contact with the outer surface of the filter element 263 for cleaning the outer surface thereof. In other embodiments of the present disclosure, the brush assembly may further include a second brush, which is installed inside the filter element, and the bristles of the second brush are in contact with the inner surface of the filter element for cleaning the inner surface thereof.

[0075] In the embodiment shown in FIGS. 1 to 3 , the driving mechanism is used to drive the filter element 263, and includes a motor 262a, a bearing 262b, a driving disk 262c and an electrode sheet 262d. Figure 2 As shown, the motor 262a is installed on the upper part of the water tank body 261, and the drive plate 262c is connected to the motor 262a and the filter element 263 respectively. The bearing 262b includes an upper bearing and a lower bearing, the upper bearing is connected to the drive plate 262c, and the lower bearing is installed at the sewage outlet. Figure 3 As shown, the electrode sheet 262d is installed on the upper side of the water tank body 261 for supplying power to the motor 262a. An electrode holder (not shown) is also provided in the water tank body 261.

[0076] The sealing assembly of the present disclosure includes a check valve 265d, which is connected to the purified water outlet 261b. When the water tank is installed on the cleaning tool, the check valve 265d is in an open state, and the purified water can flow out of the water tank through the purified water outlet 261b; when the water tank is taken out, the check valve 265d is closed, and the purified water cannot flow out of the water tank through the purified water outlet 261b, thereby preventing water leakage.

[0077] The water tank of the present disclosure may further include a bottom cover 266, which is detachably connected to the water tank body 261. In the embodiment shown in FIGS. 1 to 3, the bottom cover 266 is threadedly connected to the water tank body 261, and the sealing assembly further includes a bottom cover sealing ring 265a, which is installed in the bottom cover 266. The check valve 265d is installed on the bottom cover 266.

[0078] In the embodiment shown in FIGS. 1 to 3 , the sealing assembly further includes a filter element top sealing ring 265 b and a sewage outlet sealing ring 265 c , which are respectively installed on the top of the filter element 263 and the outside of the check valve 265 d .

[0079] The water tank disclosed in the present invention has a filtering function, and can filter and process sewage for reuse. In addition, an anti-blocking structure is provided, and the filter element can be cleaned through the relative movement of the filter element and the brush assembly, thereby increasing its filtering capacity and extending its service life.

[0080] FIG4 shows a preferred water tank assembly of the present disclosure. Figure 5 As shown, the water tank assembly of the present disclosure includes a water tank body 271 and a water pressure rod 272. The water tank body 271 is concave to form a first water tank A1 (water storage space), and the first water tank A1 is provided with a sewage outlet 271c and a second sewage inlet 271b. The water pressure rod 272 is rotatable and mounted on the water tank body 271. The water tank body 271 is also provided with a water retaining rib 271a, which extends along the length direction of the first water tank A1. Figure 5 As shown, the water retaining rib 271a has an arc surface, and part of the outer circumference of the water pressing rod 272 is attached to the arc surface. The second sewage inlet 271b is arranged on the water retaining rib 271a, and the sewage enters the first water tank A1 through the second sewage inlet 271b.

[0081] Sewage contains dirt, mud or other sticky substances, which can easily clog the water pipe after entering the cleaning tool. Therefore, a filter screen 274 can be set at the sewage outlet 271c. At this time, the sewage from the squeeze first passes through the filter screen 274, is filtered and then discharged. In this case, the side shell of the cleaning tool can be designed to be relatively thin. The aperture of the filter screen 274 can be 0.3~0.7mm, preferably 0.5mm.

[0082] The filter 274 is also easily clogged, so a first roller brush 275 may be correspondingly arranged above the filter 274 to clean the garbage on the filter 274. The first roller brush 275 is rotatable and may be driven to rotate by a power device. In the embodiment shown in FIG4 , the first roller brush 275 is driven by a power device of other parts of the cleaning tool, and the water tank assembly includes a transmission gear 273a, a bearing 273b, and a connector 273c installed in the body. The power device 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 connector 273c.

[0083] like Figure 5 As shown in FIG. 4 , when the water tank assembly is installed on the cleaning tool, the water pressure rod 272 interferes with the sponge layer of the drum 111, and the water in the sponge layer is squeezed out by the water pressure rod 272. When the drum 111 is also detachable, the squeezed water is easy to leak out from both ends of the drum. Therefore, in a preferred embodiment of the present disclosure, the water tank body 271 is also provided with a water guide 271d. When the water tank assembly is installed on 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 squeezing the drum 111. The function of the water guide 271d is to guide the water on the side of the drum 111 to the middle to prevent water leakage at both ends. The water guide 271d shown in FIG. 4 and FIG. 5 has a larger upper end and a smaller lower end, and is similar to a bull horn when viewed from the side. Of course, the water guide 271d is not limited to this structure, as long as it can achieve the corresponding function. As shown in FIG. 4 (c), there are preferably two water guides 271d, which are respectively arranged on both sides of the water pressure rod 272 (i.e., above both sides of the drum 111).

[0084] In the present disclosure, the bottom surface of the first water tank A1 is high at one end and low at the other end (sewage outlet end) 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.

[0085] The water tank assembly disclosed in the present invention has a first water tank, which has the function of caching sewage. The water tank assembly also has a rotatable water pressing rod, which rotates relative to the drum when mounted on the cleaning tool, and can more easily squeeze the sewage out of the sponge layer of the drum. In addition, the water tank assembly can be detachably mounted on the cleaning tool, which is convenient for frequent cleaning.

[0086] Figure 6~Figure 12 A cleaning tool according to a preferred embodiment of the present disclosure is shown.

[0087] The cleaning tool disclosed in the present invention comprises a cleaning module and a water circulation module. The cleaning module comprises a drum 111. The drum 111 has at least two layers, the outermost layer is a sponge layer for absorbing water and cleaning garbage. The innermost layer is a support layer made of a hard material. The drive motor can be sleeved in the drum 111, which can save space and reduce the volume of the cleaning tool.

[0088] The water circulation module includes a water tank 260 and a water tank assembly 270. The specific structures of the water tank 260 and the water tank assembly 270 are shown in Figures 1 to 5, and will not be repeated here. like Figure 5 , Figure 8 As shown, The water retaining rib 271a, the water pressing rod 272 and the drum 111 together form a second water tank A2 (water containing 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.

[0089] The water tank 260 can be installed on the cleaning head of the cleaning tool, or on the handle (such as Figure 6 The specific location can be determined according to needs.

[0090] Figure 7, Figure 8 As shown, the cleaning head of the cleaning tool of the present disclosure is equipped with a roller 111, a second roller brush 131, a garbage box 141, and a water tank assembly 270. The side shell 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 roller 111 is detachably mounted on the shell through the roller quick release button 536a and the roller quick release buckle 536b. The second roller brush 131 is detachably mounted on the shell through the roller brush quick release button 537a and the roller brush quick release buckle 537b. The water tank assembly 270 is detachably mounted on the shell through the water tank roller brush quick release 538.

[0091] like Figure 8 As shown, a shovel bar is also provided in the cleaning module, one end of which contacts 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 to clean the dry garbage on the surface of the drum 111.

[0092] One end of the roller 111 is provided with a buckle, so as to facilitate removal from the housing 500. The motor is installed inside the roller 111, and the rotating shaft is installed on the housing. The driving motor drives the hard material inside to rotate around its axis through the roller transmission mechanism, driving the sponge layer to rotate, so that the surface of the sponge layer performs a circular motion.

[0093] When the roller 111 rolls over the ground, the dry garbage particles on the ground compress and deform the sponge layer, and the sponge layer wraps the dry garbage particles by deformation, so that the dry garbage particles are separated from the ground and rotate with the roller 111. When it turns to the position of the shovel bar a, the dry garbage particles leave the ground, are squeezed by the shovel bar, and continue to rotate with the roller 111. When the shovel bar is turned and it turns to b, the sponge layer recovers and deforms due to the loss of the pressure of the shovel bar, releasing the dry garbage particles wrapped by it. Some of the dry garbage particles that cannot be released are brushed off by the bristles of the second roller brush 131. The bristles of the second roller brush 131 are in contact with the sponge layer, and the second roller brush 131 moves in opposite directions to the roller 111. The released or brushed garbage enters the garbage box 141 along the movement trajectory of the second roller brush 131.

[0094] As shown in Figure 9, Fig.10 As shown, the upper cover 510 of the present disclosure includes a purified water inlet 512 , a water spray port 513 , a spring column 514 , a housing switch 515 , a locking tongue 516 and a water pipe 517 .

[0095] Figure 9 Fig.10 In the upper cover 510 shown, there are two water spraying ports 513, which are symmetrically arranged on the upper cover 510. In other embodiments of the present disclosure, the water spraying ports 513 can be one or even one or more rows, which can be arranged as needed. Fig.10 The upper cover 510 shown is detachable, and is detachably connected to the cleaning head via a spring column 514, a housing switch 515, and a locking tongue 516.

[0096] A water pipe 517 is connected between the purified water inlet 512 and the water spray outlet 513 .

[0097] 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 a power device.

[0098] Optionally, sewage can be pumped from the first water tank A1 into the water tank 260 by a water pump. At this time, the water pump is connected to the sewage outlet 271c and the first sewage inlet 261a through a sewage pipe.

[0099] The present invention includes two filtering devices, a filter screen and a filter element, that is, the cleaning tool of the present invention can perform two-stage filtration on sewage. The water squeezed from the drum first passes through the filter screen to filter out relatively large garbage, then enters the water tank, and then passes through the filter element to filter out fine garbage. After two-stage filtration, the sewage can be turned into relatively clean purified water, which can be reused for washing the drum, greatly saving water resources, and reducing the number of times the user changes water, which is convenient to use.

[0100] When the water tank 260 is mounted to the handle as shown in the figure, the purified water discharged from the water tank 260 can flow to the cleaning head by a water pump or by relying on its own weight. If a water pump is adopted, the water pump is connected to the purified water outlet 261b and the water spray port 513 respectively through a purified water pipe.

[0101] Fig.11 In the embodiment shown, both sewage and purified water are pumped by water pumps. A first water pump 217 and a second water pump 233 are provided. The first water pump 217 is used to pump sewage, and the second water pump 233 is used to pump purified water. Fig.11 In the figure, L refers to the left side of the cleaning head and R refers to the right side of the cleaning head.

[0102] The cleaning tool of the present disclosure may also include a disinfection component. The disinfection component may include an ozone generator 223a (such as Fig.11 The ozone generator 223a passes the ozone generated by the ozone generator 223a into the transfer water tank through an air pump and an air pipe (not shown in the figure) to disinfect and sterilize the purified water to prevent the water from becoming smelly. In addition, since the water carries ozone, it can also disinfect and sterilize the ground.

[0103] Figure 6 In the embodiment shown, the ozone generator 223a is disposed on the handle 303. In other embodiments of the present disclosure, the disinfection component may also be disposed at other locations, depending on the needs. Fig.11 As shown, the transfer water tank 233 is provided with an ozone inlet 233b and a pressure balance port 223c. Ozone generated by the ozone generator 223a enters the transfer water tank through the ozone inlet 233b.

[0104] Moreover, the disinfection component can also be other disinfection devices such as UV lamps, and the ozone generator is only a preferred embodiment thereof.

[0105] The handheld portion of the cleaning tool disclosed in the present invention may also be provided with an adjustment knob, which can adjust the water output speed. When the ground is very dry, the water output can be increased to make the ground wet; when there is water on the ground, the water output can be reduced or not output, so that the cleaning tool can absorb the water on the ground.

[0106] like Figure 6 As shown, an observation window can be provided in the transfer water tank, so that the user can observe the state of the water in the transfer water tank and decide whether to inject clean water.

[0107] The cleaning tool of the present disclosure may be provided with a roller on the cleaning head. Figure 6 In the embodiment shown, there are two sets of rollers (front wheels 151 and rear wheels 152). There are two front wheels 151 and two rear wheels 152 respectively, wherein the rear wheels 152 can be connected to a power device (motor).

[0108] In addition, in the present disclosure, if the side shell corresponding to the drum 111 is relatively thick, the ground corresponding to the shells on both sides of the drum 111 will inevitably not be cleaned by the drum 111, thus causing a cleaning blind spot. In order to clean this blind spot, at least one side brush can be respectively provided on the side of the drum 111. The two side brushes can be symmetrically provided on the shells on both sides of the drum 111.

[0109] The end (front side) of the housing of the cleaning tool of the present disclosure where the roller 111 is installed may also be equipped with an anti-collision strip (not shown in the figure) to prevent collision and damage to the housing during the process of cleaning the floor. A searchlight (not shown in the figure) may also be installed to help the user to clean better when cleaning dark places such as under the bed.

[0110] Fig.12 This is a simplified diagram of the water circuit of an embodiment of the present disclosure. Sewage is squeezed out of the drum and enters the water tank for filtration. After filtration, it is pumped to the transfer water tank through a pump, and ozone is added to the transfer water tank. Then, it is pumped back to the drum to clean the drum. This reciprocating process realizes the water circulation.

[0111] In some embodiments of the present disclosure, the user adds clean water to the water tank 260, holds the handheld part, turns on the switch, and starts the device. 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 forward and backward, and before it touches the ground, the sponge layer on the drum 111 is slightly wet (not saturated with water). After touching the ground, the slightly wet sponge layer absorbs liquid garbage on the ground while cleaning solid garbage on the ground.

[0112] With the cooperation of the shovel bar 112, the large solid waste particles brought by the roller 111 pass through the gap between it and the shovel bar 112 to reach point b, and then enter the garbage box 141 along the movement track of the second roller brush 131. The small waste particles are embedded in the sponge layer, and as the roller 111 moves, they reach point b, are brushed down by the bristles of the second roller brush 131, and enter the garbage box 141 along the movement track of the second roller brush 131.

[0113] The drum 111 continues to roll and reaches the water pressing 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 the drum 111 dry and then spraying it with cleaner water during use. That is, during use, the drum 111 is always being cleaned. The squeezed sewage flows into the first water tank A1 through the second water tank A2, then enters the water tank 260 through the sewage pipe, and then enters the transfer water tank after being filtered by the filter element 263, and then is sprayed onto the drum 111 through the purified water pipe under the action of the water pump to clean the drum 111. This cycle continues to clean the ground.

[0114] At the same time, the ozone generator 223a continuously sprays ozone into the transfer water tank 233, thereby achieving simultaneous disinfection and sterilization of the water in the water tank A and the ground.

[0115] When using the cleaning tool of the present invention to clean the ketchup on the ground, the user first adds clean water to the water tank 260, holds the hand-held part, turns on the switch, and starts the device. 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 forward and backward, and the drum 111 moves accordingly. The drum 111 contacts 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 drum 111 continues to rotate and reaches point b, where the sponge layer contacts the second roller brush 131. The ketchup cannot be brushed off by the second roller brush 131 and still adheres to the sponge layer at point b.

[0116] The drum 111 continues to roll and reaches the water pressing 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 water, the ketchup is released from the sponge layer and enters the second water tank A2, and then filtered out through the filter net 274 and the filter element 263. From then on, the ketchup is cleaned. The purified water obtained by filtration is then sprayed onto the drum 111 through the purified water pipe under the action of the water pump to clean the drum 111.

[0117] In the present disclosure, water can be circulated multiple times, and garbage (dust) can be cleaned up smoothly. The present disclosure refers to this technology as water-dust circulation cleaning technology.

[0118] The present invention utilizes water-dust circulation cleaning technology to achieve self-cleaning of the drum, and combines sweeping, mopping, washing and twisting together, which greatly facilitates users and can achieve very good cleaning effects, especially for extremely difficult-to-handle sticky garbage such as ketchup and chocolate sauce.

[0119] Obviously, the above embodiments are merely examples for clearly illustrating the present disclosure, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present disclosure.
