Description

[0001] This application is a divisional application of Chinese patent application No. 202010073673.5 and invention name “A self-cleaning mop and sweeper”, 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 cleaning head and a self-cleaning mop and sweeper. Background Art

[0003] With the development of modern technology, there are many cleaning tools, including brooms, mops, floor wipes and vacuum cleaners, etc. Vacuum cleaners are very common floor cleaning tools, but they are very noisy, making people very uncomfortable, and their way of cleaning 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, 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

[0061] 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.

[0062] The terms "first", "second", "third", and "fourth" and the like 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 may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products, or devices.

[0063] 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.

[0064] 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.

[0065] The self-cleaning mop sweeper disclosed in the present invention is used for cleaning floors, especially smooth and flat small-area floors, such as home and kitchen floors. The self-cleaning mop sweeper disclosed in the present invention is particularly suitable for cleaning mixed garbage containing dry garbage, wet garbage and viscous materials such as noodles, porridge, ketchup and the like.

[0066] Figures 1 to 10 A preferred self-cleaning mop sweeper of the present disclosure is shown.

[0067] The self-cleaning mopping machine provided by the present disclosure may include: a housing 500, a cleaning module and a water circulation module. The cleaning module includes a garbage box 141, a roller 111, a shovel bar 112, a water pressure baffle bar 122 and a scraper bar assembly 133 respectively installed on the housing 500. The outside of the roller 111 is a sponge layer 111b. One end of the shovel bar 112 is in contact with the ground, and the other end is located above the garbage box 141. The shovel bar 112 has an arc-shaped working surface, and there is a uniform gap of a certain distance between the arc-shaped working surface and the outer circumferential surface of the roller 111. The gap forms a garbage channel, and the solid garbage cleaned from the ground enters the garbage box 141 through the garbage channel.

[0068] The drum 111 has at least two layers, the outermost layer is a sponge layer 111b, which is used to absorb water and clean 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.

[0069] The roller 111 can be detachably provided with a buckle at one end, so as to be easily detached from the housing 500. The motor is installed inside the roller 111, and the rotating shaft is installed on the housing 500. The driving motor drives the hard material inside to rotate around its axis through the roller transmission mechanism, driving the sponge layer 111b to rotate, so that the surface of the sponge layer 111b performs a circular motion.

[0070] 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.

[0071] The water-pressing baffle 122 interferes with the sponge layer 111b of the drum 111, and is used to squeeze the sponge layer 111b to squeeze out the water in the sponge layer 111b. Optionally, the interference amount between the water-pressing baffle 122 and the drum 111 is 2-4 mm.

[0072] The scraper assembly 133 includes a friction end 133a and a drainage end 133b. Figure 3 As shown, both the friction end 133a and the drainage end 133b interfere with the roller 111. Optionally, the interference amount is 1 to 2 mm, preferably 1.5 mm.

[0073] The large garbage brought up by the drum 111 can enter the garbage box 141 under the effect of its own weight, but small solid garbage or sticky garbage is difficult to separate from the sponge layer of the drum 111. If it is not separated first, the sewage squeezed from the drum 111 will carry a large amount of small garbage. The friction end 133a of the scraper assembly 133 is embedded in the sponge layer 111b and is located above the garbage box 141, which can 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.

[0074] The drainage end 133b is used to drain the water squeezed from the drum 111 into the water tank A (water containing space). Figures 1 to 10 The drainage end 133b of the self-cleaning device shown is embedded in the sponge layer 111b, and this arrangement can prevent the squeezed water from flowing along the roller 111 to the floor or other parts of the floor cleaning tool to the greatest extent. Optionally, the drainage end 133b of the scraper assembly 133 can also be attached to the sponge layer 111b, which can also play a corresponding drainage role, but in this case the drainage end 133b needs to be made of a flexible rubber material so that it can be better attached to the roller 111.

[0075] like Figure 3 As shown, the water tank A of this embodiment is formed by the drum 111, the water pressure baffle 122, the scraper assembly 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.

[0076] The water inlet and outlet of the water tank can be respectively arranged at the two ends of the water tank (such as Figure 4 shown). Figure 4 The direction of the arrow in is the direction of water flow in the cleaning head, the water inlet of the water tank is on the right, and the water outlet of the water tank is on the left. Clean water or purified water enters from the water inlet, and the sewage after cleaning the drum 111 flows out from the water outlet of the water tank. Water enters at one end and flows out at the other end, forming a dynamic water flow, thereby cleaning the drum 111. The sticky garbage adhered to the sponge layer 111b of the drum 111 can be released from the sponge layer 11b at the water tank A under the action of water and enter the water tank A. The top of the scraper assembly can be inclined, and one end of the water inlet of the water tank is higher than the end of the water outlet. At this time, the water flows in the water tank A by its own weight. The position of the water inlet of the water tank can also be the same as the position of the water outlet. At this time, the water in the water tank A can be sucked out from the water outlet by the action of a reliable power device (such as a water pump or an air pump).

[0077] Water inlets may be provided at both ends of the water tank A. In this case, water flows from the two water inlets from both ends to the middle of the water tank A. A water nozzle may be provided on the housing 500. The water nozzle is located at the middle upper end of the water tank A and is connected to the sewage pipe. Under the action of the power device, sewage is sucked out of the water tank A through the water nozzle and enters the sewage pipe.

[0078] Clean water or purified water can also be sprayed from the upper end of the water tank A into the water tank A. At this time, at least one row of water spray ports is arranged on the upper shell. Clean water or purified water is sprayed from the water tank A from the water spray ports to clean the drum 111, and then is sucked out of the water tank A under the action of its own weight or a power device.

[0079] You can also inject more water and use the water tension to make the water flow to the sewage outlet.

[0080] In addition, a spiral protrusion may be provided on the drum 111 to accelerate the water flow. The spiral protrusion extends from one end of the drum 111 to the other end to guide water from the water inlet to the water outlet of the water tank A. The spiral protrusion may also be in two sections, extending from both ends to the middle, thereby guiding water from both sides to the middle.

[0081] The water circulation module of the present disclosure includes a water tank 250, a sewage pipe (not shown in the figure) and a purified water pipe (not shown in the figure) respectively installed on a housing 500. Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, the water tank 250 is an integrated water tank, which is detachably mounted on the cleaning head. The water tank 250 is provided with a pop-up switch 253 and a locking tongue 256, and the pop-up switch 253, the locking tongue 256, and the spring pin 531 on the housing 500 cooperate with each other to install or remove the water tank 250.

[0082] The water tank 250 includes a sewage box 251, a filter box 254 and a purified water box 252. The sewage box 251 includes a sewage inlet 251a, and the purified water box 252 includes a purified water outlet 252a. The sewage inlet 251a and the purified water outlet 252a are provided with a one-way valve (such as Fig. 9 As shown), the sewage inlet 251a is connected to the sewage outlet pin 532 on the shell, and the purified water outlet 252a is connected to the purified water outlet pin 533 on the shell, which can ensure that when the water tank 250 is removed from the cleaning head, the water in the water tank 250 will not overflow from the sewage inlet 251a or the purified water outlet 252a.

[0083] The sewage pipe is connected to the water outlet of the water tank and the sewage inlet 251a of the sewage box 251. The purified water pipe is connected to the water inlet of the water tank and the purified water outlet 252a of the purified water box 252.

[0084] A filter box 254 is installed between the sewage box 251 and the purified water box 252. The filter box 254 is used to filter large particles of garbage in the sewage. Figure 8 As shown, the filter box 254 is detachably mounted on the water tank 250. A water tank flip cover 255 is provided at the position of the water tank 250 corresponding to the filter box 254, for taking and placing the filter box 254. The filter box 254 is also provided with a filter box top cover 254a.

[0085] Figures 7 to 9 The filter box shown is a closed type, and a power device is provided at the purified water outlet end. Under the action of the power device, purified water is sucked out of the water tank 250 from the purified water outlet 252a, and the water tank 250 forms a negative pressure, thereby sucking sewage from the sewage inlet 251a into the water tank 250, and then filtered by the filter box 254 and enters the purified water box 252. The filtration of sewage is completed in this reciprocating manner.

[0086] 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 box 252 and the water inlet of the water tank through the purified water pipe.

[0087] A power device may also be provided on the sewage box 251. The power device may include a water pump or an air pump. When it is a second water pump, the second water pump is connected to the sewage inlet 251a of the sewage box 251 and the water outlet of the water tank through a sewage pipe.

[0088] 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 a corresponding air extraction pipe needs to be provided. In this case, the sewage will not contact the motor, will not affect the motor, and the life of the motor is long. An air extraction port is also provided on the sewage box 251, one end of the air extraction pipe is connected to the air extraction port, and the other end is connected to the first air pump. When working, the first air pump extracts the gas inside the sewage box 251 to form a negative pressure, and the end of the sewage pipe 212 used for sucking sewage sucks the sewage from the sink A into the sewage box 251.

[0089] The first air pump is provided with an air outlet. When the sewage box 251 is full, the sewage will enter the air pump and flow out from the air outlet. In order to prevent the sewage from flowing everywhere, the sewage pipe may also include an overflow pipe. One end of the overflow pipe is connected to the air outlet of the first air pump, and the other end may be aligned with the drum 111, so that the sewage is directly discharged onto the drum 111.

[0090] like Figure 1 , Figure 2 and Fig.10As shown, the self-cleaning mop sweeper of the present disclosure may also include a disinfection component 222. Among them, the disinfection component 222 may include an ozone generator 222a, a second air pump 222b and an air pipe (not shown in the figure). Among them, the second air pump 222b is connected to the ozone generator 222a and the water tank A respectively through the air pipe. The ozone generated by the ozone generator 222a enters the water tank A through the air pipe to disinfect and sterilize the water in the water tank A to prevent the water from becoming smelly. In addition, since the water in the water tank A is ozone-containing, the ground can also be disinfected and sterilized.

[0091] Figure 1 , Figure 2 and Fig.10 In the illustrated embodiment, the disinfection component 222 is also disposed on the handle 303. In other embodiments of the present disclosure, the disinfection component 222 may also be disposed at other locations, depending on the needs.

[0092] Furthermore, the disinfection component 222 can also be other disinfection devices such as a UV lamp, and the ozone generator is only a preferred embodiment thereof.

[0093] like Figure 1 As shown, the handheld portion of the self-cleaning mopping device of the present disclosure may also be provided with an adjustment knob 306 and a key switch 307. The adjustment knob 306 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 self-cleaning mopping device can absorb the water on the ground. The key switch 307 is a general circuit switch, which is pressed to start the self-cleaning mopping device.

[0094] like Figure 3 As shown, a water tank observation window 511 can be provided on the housing 500 corresponding to the upper end of the water tank A. This allows the user to observe the water tank A and decide whether to add clean water.

[0095] The cleaning head of the self-cleaning mop and sweeper disclosed herein may be equipped with rollers. Figure 5 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 wheel 152 can be connected to a power device (motor).

[0096] 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 blind spot for cleaning. In order to clean this blind spot, at least one side brush 190 (such as Figure 5 shown).

[0097] In some embodiments of the present disclosure, the user adds clean water to the water tank 250, holds the hand-held part, turns on the switch 307, and starts the self-cleaning mop. Clean water is sucked to the water inlet of the water tank A along the purified water outlet 252a, and then the drum 111 is brought with water. 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.

[0098] 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 garbage box 141. The small waste particles and / or sticky waste are embedded or adhered to the sponge layer, and as the roller 111 moves, they reach the friction end 133a of the scraper assembly 133. Under the action of the friction end 133a, the small waste particles embedded or adhered to the sponge layer are brushed off and enter the garbage box 141 under the action of their own weight.

[0099] 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 lower end of the water pressure baffle 122 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 squeezed sewage is drained into the water tank A through the drainage end 133b. At the water tank A, the sticky garbage is released from the sponge layer 111b of the drum 111 under the action of water and enters the sewage. The sewage enters the sewage box 251 of the water tank 250 through the sewage pipe, and then enters the purified water box 252 after being filtered by the filter box 254. Then, under the action of the power device (water pump), it is reused in the water tank A through the purified water pipe to clean the drum 111. This cycle continues to achieve the cleaning of the floor.

[0100] At the same time, the ozone generator 222a continuously sprays ozone into the water tank A, thereby disinfecting and sterilizing the water in the water tank A and the ground at the same time.

[0101] The housing of the self-cleaning mop and sweeper of the present disclosure at the end where the roller 111 is installed can also be equipped with an anti-collision strip (not shown in the figure) to prevent collision during the cleaning process and damage to the housing 500. A searchlight (not shown in the figure) can also be installed to help the user to clean better when cleaning dark places such as under the bed.

[0102] Figures 11 to 13Another form of water tank A of the present disclosure is shown, which is an integrated structure, not formed by the drum 111, the water pressure baffle 122, the scraper assembly 133 and the housing 500, and is detachably mounted on the housing 500. Of course, this water tank A can also be fixedly mounted on the housing 500, and can be set according to actual conditions.

[0103] like Figures 11 to 13 As shown, the water tank A includes a water channel A-1, a purified water inlet A-2, a sewage outlet A-3, a sewage inlet A-4 and a scraper assembly A-5. The purified water inlet A-2 and the sewage outlet A-3 are respectively arranged at both ends of the water tank A. The scraper assembly A-5 is arranged on the bottom surface of the water tank A.

[0104] The scraper strip assembly A-5 in this embodiment is Figures 1 to 10 The structure of the scraper assembly 133 shown is similar, including a friction end and a drainage 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 roller 111. Optionally, the interference amount is about 1 to 2 mm, preferably 1.5 mm.

[0105] The sewage inlet A-4 is formed by the gap between the drainage end and the water channel A-1.

[0106] The friction end of the scraper assembly A-5 interferes with the sponge layer 111b and is located above the garbage box 141, and can separate most of the garbage embedded and / or adhered to the sponge layer 111b of the drum 111 from the sponge layer 111b. 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.

[0107] The drainage end is used to drain the water squeezed from the drum 111 to the water channel A-1 of the water tank A. The drainage end interferes with the sponge layer 111b, and this arrangement can prevent the squeezed water from flowing along the drum 111 to the ground or other parts of the floor cleaning tool to the greatest extent. Similarly, the drainage end of the scraper assembly A-5 can also be attached to the sponge layer 111b, which can also play a corresponding drainage role.

[0108] Optionally, the scraper strip assembly A-5 is made of a flexible material (such as rubber). Since both the flexible material and the sponge layer are relatively soft, a soft-on-soft effect is formed, thereby achieving a sealing effect.

[0109] exist Figures 11 to 13In the illustrated embodiment, the water squeezed out from the sponge layer 111b of the drum 111 by the water pressure baffle 122 enters the water channel A-1 through the sewage inlet A-4 under the guidance of the drainage end of the scraper assembly A-5, 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. When the water pressure of the clean water or purified water is relatively high, or the water flow is relatively large, the clean water can reach the drum 111 from the sewage inlet A-4 along the drainage end of the scraper assembly A-5, thereby cleaning the drum 111. Because the sewage enters the water channel A-1 from the sewage inlet A-4, the flow directions of the clean water or purified water and the sewage are opposite, which will cause water agitation, which is equivalent to rinsing the drum 111 all the time.

[0110] When the water tank A is detachable, it can be connected to the housing 500 by snapping. Its purified water inlet A-2 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.

[0111] The rest and Figures 1 to 10 The embodiments are similar and will not be described again here.

[0112] 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.

[0113] 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.

[0114] Obviously, the above embodiments are merely examples for clearly explaining the present invention, 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 protection scope of the present invention.
