Abstract
Description
[0001] This application is a divisional application of Chinese patent application No. 202010073672.0 and invention name “A floor cleaning tool”, the contents of which are incorporated herein by reference. Technical Field
[0002] The present disclosure belongs to the technical field of cleaning equipment, and in particular, relates to a floor cleaning tool. Background Art
[0003] With the development of modern technology, there are many kinds of floor cleaning tools, including brooms, mops, floor wipes and vacuum cleaners. Vacuum cleaners are very common floor 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 the 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 floor 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 requires multiple washings), 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

[0036] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0037] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.
[0038] The terms "first", "second", etc. in the specification and claims of the present disclosure and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.
[0039] 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.
[0040] Figure 1 The water tank 231 for a floor cleaning tool disclosed in the present invention is shown. It includes: a water storage tank 231a and a water guide tank 231b. The water storage tank 231a is provided with a first water inlet for storing water. The bottom surface of the water guide tank 231b is inclined and wedge-shaped, and is provided with a second water inlet and a water outlet. Among them, the second water inlet is wide and the water outlet is narrow. The water outlet is connected to the water inlet of the water storage tank 231a. The water squeezed from the drum of the floor cleaning tool flows into the water storage tank 231a through the water guide tank 231b under the action of its own weight.
[0041] This structure of the water guide groove 231b allows the water squeezed from the drum to flow smoothly into the water storage groove 231b without overflowing onto the ground.
[0042] Figure 1 The water tank 231 shown also includes a scraper 231c. The scraper 231c is disposed at the first water inlet of the water guide groove 231b to guide the water squeezed from the drum 111 into the water guide groove 231b. Optionally, the drainage end of the scraper 231c is attached to the drum 111 (such as Figure 3 As shown in the figure, such an arrangement can prevent the squeezed water from flowing along the drum 111 to the place or other parts of the floor cleaning tool to the greatest extent. In other embodiments of the present disclosure, the drainage end of the scraper bar 231c may also interfere with the drum 111. With such an arrangement, there is no gap between the drum 111 and the drainage end of the scraper bar 231c. Optionally, the scraper bar 231c is made of a flexible rubber material so that it can be better attached to the drum 111. The drainage end of the scraper bar 231c interferes with the drum 111, which means that the drainage end will partially squeeze the surface of the drum 111.
[0043] When the floor cleaning tool is working, it is easy to cause the water in the water tank 231a to slosh, which may cause the water to flow back from the water tank 231a out of the upper end (first water inlet end) of the water guide trough 231b, overflowing onto the ground or other parts of the floor cleaning tool. When the water tank 231a is full of water, the water is more likely to overflow, causing the floor cleaning tool to be unable to work. In order to prevent water from flowing back from the water tank 231a out of the first water inlet of the water guide trough 231b, a water retaining bar (not shown in the figure) may be provided on the water guide trough 231b. The water retaining bar of the present disclosure is close to the upper end of the water guide trough 231b, has a certain height and a certain length, and its height and length can be set according to actual needs. The water retaining bar is preferably arranged in the middle of the water guide trough 231b, and the distance between the two sides and the side walls of the water guide trough 231b is equal.
[0044] The sewage squeezed out from the drum 111 generally contains fine solid garbage. In order to prevent the solid garbage from clogging the water inlet of the water tank 231a and the water tank 231a, a filter assembly can be installed at the water inlet of the water tank 231a to filter the garbage in the water. Figure 1 In the illustrated embodiment, the filter assembly is a filter plug 231d. The water in the water channel 231b flows into the water storage tank 231a through the filter plug 231d, thereby filtering out most of the solid waste. Preferably, the filter plug 231d is detachably mounted on the water inlet of the water storage tank 231a, and the filter plug 231d can be easily cleaned. The greater the height of the filter plug 231d (the maximum height can be equal to the height of the water storage tank 231a), the more waste it can hold, and the specific height can be set according to demand.
[0045] In other embodiments of the present disclosure, the filter assembly may also be a filter screen, which is installed on the water inlet of the water tank 231a. The water in the water guide trough 231b flows into the water tank 231a through the filter screen, thereby filtering out most of the solid waste. In this case, the filter screen cannot be disassembled and needs to be cleaned with the help of other tools.
[0046] In the present disclosure, the water tank 231 can be made detachable and only used for storing water. When the water is full, it can be directly poured out. It can also be fixed on the floor cleaning tool. In this case, the water tank 231a is also provided with a water outlet. The purified water filtered by the filter assembly can be reused on the drum through a power device (such as a water pump), thereby realizing the recycling of water.
[0047] When the floor cleaning tool is working, solid garbage will be carried on the drum. Large garbage can enter the garbage bin of the floor cleaning tool under the action of its own weight, but small garbage is difficult to separate from the drum. If it is not separated first, the sewage squeezed from the drum will carry a large amount of small garbage. In order to separate the garbage from the drum, the water tank 231 of the present disclosure may also include a brush 231e. Figure 2 for Figure 1 The enlarged view of part A shown clearly shows the structure of the brush 231e. The brush 231e is arranged in one or more rows and is located below the water guide groove 231b and above the trash bin. When the water bin is mounted on the floor cleaning tool, the bristles of the brush 231e contact the surface of the drum 111. When the drum rotates, the brush 231e rubs against the drum, thereby brushing the garbage from the drum into the trash bin.
[0048] Figures 3 to 5 The preferred embodiment of the floor cleaning tool disclosed herein includes the water tank 231. It includes a housing 500, a drum 111, a water pressure baffle 122, a water tank 231 and a water pump 233. The floor cleaning tool disclosed herein is used for cleaning floors, especially smooth and flat small-area floors, such as home and kitchen floors. The floor cleaning tool disclosed herein is particularly suitable for cleaning mixed garbage (sticky garbage) mixed with dry garbage, wet garbage and viscous materials such as noodles, porridge, ketchup, etc.
[0049] The drum 111 is mounted on the housing 500. 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 hard material. The drive motor can be sleeved in the drum 111, which can save space and reduce the volume of the floor cleaning tool.
[0050] The drum 111 may be detachably mounted (e.g. Figure 8The motor 113a is installed inside the drum 111, and the rotating shaft 113c is installed on the housing 500. The motor 113a drives the internal hard material to rotate around its axis through the transmission mechanism, driving the sponge layer 111b to rotate, so that the surface of the sponge layer 111b makes a circular motion.
[0051] The density and hardness of the sponge layer 111b of the drum 111 have a direct impact on the water absorption performance and water storage rate (also known as water lock). When the sponge density increases to a certain extent, the water absorption performance will decrease, the hardness will increase, and the water storage rate will increase; conversely, when the sponge density decreases, the water absorption will increase, the hardness will decrease, and the water storage rate will decrease.
[0052] In some embodiments of the present disclosure, the sponge layer 111b may be made of polyvinyl alcohol (PVA) foam. The density of PVA sponge is 0.5-0.25 g / cm3, and the water absorption rate is 0.5-1.5 g / cm3. The Shore hardness of PVA sponge is 40-70. The water storage rate of PVA sponge is 0.2-1.0 g / cm3. Such a sponge layer has the above-mentioned characteristics, so compared with the existing single-layer ordinary sponge roller, it has better effects:
[0053] The sponge layer has both suitable water absorption performance and water storage rate, as well as suitable density and hardness. This allows the sponge to deform just right during the mopping process, wrapping the garbage particles, and when turning past the restriction of the shovel bar, it can use its own elasticity to eject most of the garbage particles, detaching them from the sponge layer and dropping them into the dry garbage collection unit, without missing anything. Moreover, when dealing with accumulated water on the ground, the sponge can absorb more water, leaving less water on the mopped bottom surface.
[0054] This single-layer sponge layer will not have the disadvantage of the double-layer sponge being squeezed and separated, thus affecting the life of the roller.
[0055] Optionally, the thickness of the sponge layer 111b is generally 3-15 mm, and its deformation is sufficient to wrap common granular garbage. A household cleaning tool equipped with a 5-10 mm thick sponge layer can handle common dry garbage on the household floor.
[0056] Figure 7 FIG. 1 is a schematic diagram of a motor 113 a in a floor cleaning device when the roller 111 is not installed in one embodiment of the present disclosure.
[0057] The water pressure baffle 122 is disposed inside the housing 500 and interferes with the sponge layer of the drum 111 (eg Figure 3The water pressure baffle 122 is provided with a water spraying port at the upper end thereof, which is used to spray water to the sponge layer of the drum 111, thereby cleaning the sponge layer of the drum 111. The water spraying port can be arranged in one row or in multiple rows, or can be arranged in a row as shown in FIG. Figure 3 As shown, it is configured as a water spray channel with a wide upper end and a narrow lower end.
[0058] Figures 3 to 8 In the embodiment shown, the water tank 231 is fixed on the floor cleaning tool, and a water outlet is also provided on the water storage tank 231a. The purified water filtered by the filter assembly can be reused on the drum through the power device, thereby realizing the recycling of water.
[0059] Figures 3 to 8 In the embodiment shown, the power device is a water pump 233. The water pump 233 is installed inside the housing 500, one end of which is connected to the water outlet of the water tank 231 through a first water pipe 232a, and the other end of which is connected to the water outlet of the water pressure baffle 122 through a second water pipe 232b. Figures 1 to 3 In the illustrated embodiment, there are two second water pipes 232b, which are respectively connected to the left and right ends of the water pressure baffle 122, so that the sprayed water is more uniform.
[0060] The water pressure baffle 122 squeezes the sponge layer of the drum 111, and the squeezed sewage flows into the water guide groove 231b under the guidance of the scraper bar 231c, and enters the water outlet groove 231a after being filtered by the filter plug 231d. The purified water obtained after filtration is reused under the action of the water pump 233 to clean the drum 111 again. This cycle is repeated to achieve the cleaning effect of the drum 111. Except for the need to add clean water to the water tank when using it for the first time, the water in the floor cleaning tool disclosed in the present invention can be recycled to achieve the effect of self-cleaning.
[0061] The floor cleaning tool disclosed herein has a simple structure, is almost noiseless when in use, and can also realize the recycling of water.
[0062] Figures 3 to 8 The illustrated floor cleaning tool also includes a dustbin 141 and a scooping bar 112 .
[0063] The trash bin 141 is mounted on the housing 500 and is located below the water guide groove 231b. This arrangement can save space. The trash bin 141 can be detachable for easy cleaning.
[0064] The shovel bar 112 has an arc-shaped working surface, one end of which contacts the ground when working. There is a uniform gap of a certain distance between the arc-shaped working surface and the outer circumference of the drum 111, and the gap forms a garbage channel. Solid garbage swept from the ground enters the garbage bin 141 through the garbage channel.
[0065] When the drum 111 rolls over the ground, the dry garbage particles on the ground compress and deform the sponge layer 111b, and the sponge layer 111b wraps the dry garbage particles through deformation, so that the dry garbage particles are separated from the ground and rotate with the drum 111. When the drum 111 reaches the position of the shovel bar 112, the dry garbage particles leave the ground and are squeezed by the shovel bar 112, and continue to rotate with the drum 111. When the drum 111 passes the shovel bar 112 and reaches the entrance of the garbage box 141, the sponge layer 111b recovers and deforms due to the loss of the pressure of the shovel bar 112, and the dry garbage particles wrapped by the sponge layer 111b are released and bounced into the garbage box 141.
[0066] The floor cleaning tool of the present disclosure may further include at least two wheels 150 , which are mounted on the bottom of the water tank 231 to enable the floor cleaning tool to move forward or backward.
[0067] In addition, the floor cleaning tool of the present disclosure may further include a handheld portion (not shown in the figure). The handheld portion is connected to the housing 500, and the user grasps the handheld portion to move the floor cleaning tool forward or backward to clean the floor. The switch of the water pump 233 may be set on the handheld portion.
[0068] The housing of the floor cleaning tool of the present disclosure at the end 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 500 during the process of cleaning the floor.
[0069] The floor cleaning tool disclosed herein, except for the roller 111 and the wheel 150, has no other components in contact with the floor.
[0070] The floor cleaning tool disclosed in the present invention can effectively clean liquid garbage and realize self-cleaning of the drum. When equipped with a garbage box and a shovel bar, it can also clean large-particle solid garbage.
[0071] In some embodiments of the present disclosure, the user adds clean water to the water tank 231, holds the hand-held part, turns on the switch of the water pump 233, and starts the water pump 233. The water pump 233 draws water from the water tank 231a to the water spray port of the water pressure baffle 122, and sprays the water onto the sponge layer of the drum 111. The user pushes the floor cleaning tool forward and backward, and the drum 111 moves accordingly. Before contacting the ground, the sponge layer on the drum 111 is slightly wet (not saturated with water). After contacting the ground, the slightly wet sponge layer absorbs liquid garbage on the ground while cleaning solid garbage on the ground. Sticky garbage adheres to the sponge layer.
[0072] With the cooperation of the shovel bar 112, the large solid waste particles lifted by the roller 111 pass through the gap between the roller 111 and the shovel bar 112 and reach the trash bin 141. The small waste particles are embedded or adhered to the sponge layer, and as the roller 111 moves, they reach the brush 231e. Under the action of the brush 231e, the small waste particles or hair embedded or adhered to the sponge layer are brushed off and enter the trash bin 141 under the action of their own weight.
[0073] The drum 111 continues to roll and reaches the water pressure baffle 122. The water pressure baffle 122 squeezes the sponge layer to squeeze out the sewage in the sponge layer. The upper end of the water pressure baffle 122 continuously sprays water, and the lower end continuously squeezes the sponge layer of the drum 111, which is equivalent to the water pressure baffle 122 continuously cleaning the drum 111 during the use of the floor cleaning tool. The sticky garbage is released from the sponge layer 111b of the drum 111 here and enters the sewage. The squeezed sewage is drained into the water guide groove 231b through the scraper bar 231c, and then filtered through the filter plug 231d and enters the water outlet groove 231a. The purified water obtained after filtration is reused under the action of the water pump 233, and is sucked into the water spray port of the water pressure baffle 122 again to clean the drum 111. This cycle continues to achieve the cleaning of the floor.
[0074] In the present disclosure, water can be circulated multiple times, and garbage (dust) can be cleaned smoothly. The present disclosure refers to this technology as water-dust circulation cleaning technology.
[0075] 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.
[0076] 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.
