Description

A floor cleaning device

Technical field

The present invention relates to the field of floor washing machines and floor mops, and in particular to a cleaning equipment with a self-cleaning function for floor cleaning.

Background technique

Commonly used floor cleaning equipment on the market currently include vacuum cleaners, sweeping robots, mops, floor mops, and floor washers. These equipment can only be used for dry sweeping or wet mopping, and there are many water stains remaining on the mopped ground, which is not only easy to It causes the user to fall and easily step on the dirt again, which brings great inconvenience to life. Of course, various floor washing machines that have become more popular in recent years have good mopping and vacuuming effects. Floor washing machines usually have dry and wet sweeping functions. Mopping function, but its working principle is usually to use a scraper to scrape off the water stains on the roller brush. In fact, it cannot achieve the "drying" effect without water stains. This method is not only easy to damage the scraper and roller brush, but also damages the roller brush. Roller brushes produce greater resistance; at the same time, in order to improve the cleaning effect, floor washing machines often come with a vacuum cleaner module in addition to roller brushes for mopping and washing the floor. Therefore, they are noisy, and the product structure is complex, the cost is high, and the selling price is expensive.

The mainstream technology of existing floor washing machines or mopping machines is a vacuum cleaner mechanism plus a roller brush structure. However, products with this technical route often need to use high-speed motors in order to pursue large suction, because they need to use negative air pressure for suction. Sewage and dirt, and high-speed motors lead to loud product noise. If the motor is silent, the cost will be high. The complex structure further increases the cost. The product itself is also relatively heavy, which is not conducive to user movement and is easy to break. Due to the high power consumption of high-speed motors, battery life is a big problem. In order to improve battery life, the number of battery packs is increased, which increases the cost and weight of the product.

There is also a technical route product in the existing products. Its product structure is a roller brush plus a scraper assembly. However, because there is no negative pressure, the decontamination effect is poor; because the scraper is used to scrape the entire roller brush surface, thus Let the dirt and sewage flow into the sewage tank using the principle of gravity. On the one hand, the opening of the sewage tank will be very large, otherwise it cannot be connected with the scraper. On the other hand, the capacity of the sewage tank is limited, and the location of the sewage outlet needs to be It needs to be set lower so that the sewage can flow smoothly to the sewage tank.

Compared with the existing technology, this patented technical solution has at least the following beneficial technical effects.

Although there are many products of existing floor washing machines or mopping machines, the main technical solution is a vacuum cleaner mechanism plus a roller brush structure. The more typical ones are various products of Tianke Company and Zhuimi Company. However, products with this technical route often need to use high-speed motors in order to pursue high suction power, because negative air pressure is used to suck sewage and dirt. High-speed motors cause loud product noise. If the motor is silent, the cost will be high;

At the same time, it is necessary to separate sewage and dirt, and set up relevant structures to prevent sewage from entering the motor and causing damage. The product structure is complex, which further leads to high costs; the design space of the product is limited, and the water tank often needs to be set on the rod body, and even the sewage tank needs to be Both the product and the clean water tank are set on the pole body, which makes the center of gravity of the product unstable and easy to fall; the complex structure makes the product itself relatively heavy, which is not conducive to user movement.

More importantly, due to the high power consumption of high-speed motors, battery life is a big problem. Usually, it is very rare for products on the market to last for 60 minutes under high-power working conditions. In order to improve battery life, Increasing the number of battery packs not only increases the cost, but also further increases the weight of the product.

Existing products also have a technical route. For example, the floor washing machine of Dishui Company does not have a vacuum cleaner structure. Its product structure is a roller brush plus a scraper assembly. The scraper is used to scrape the sewage dirt on the roller brush into the sewage tank. middle. Although this technical route omits the structure of negative air pressure in the vacuum cleaner, because no negative pressure is formed, the decontamination effect is poor; on the one hand, the scraper is less efficient at scraping dirt; on the other hand, it is not effective Remove the moisture on the roller brush, leaving more water stains on the ground; if the scraper exerts increased pressure on the roller brush, the effect of squeezing and removing water by the roller brush may be improved, but the resistance between the components It is large, easy to damage, easy to get stuck when rotating, and will press the surface of the fiber roller brush too "flat", which is not conducive to the roller brush absorbing ground garbage. At the same time, since the scraper is used to scrape the entire surface of the roller brush, dirt and sewage are allowed to flow into the sewage tank using the principle of gravity. On the one hand, the opening of the sewage tank will be very large, otherwise it cannot be connected with the scraper. , On the other hand, the capacity of the sewage tank is limited, and the location of the sewage outlet needs to be set lower to allow the sewage to flow to the sewage tank.

The floor cleaning device of the floor washer or mop involved in this patented technical solution is suitable for hard floors such as floor tiles, wooden floors, cement floors, etc. It cleverly utilizes the principle of Archimedes spiral water pump and innovates this principle. Developed a unique cleaning module that combines the screw with the dirt tank and roller brush. The roller brush assembly, which is arranged sequentially in the horizontal direction, closely cooperates with the screw assembly and dirt tank assembly to interact with each other. On the one hand, the roller brush can be At the same time, the interaction between the screw assembly, the roller brush assembly and the sewage tank assembly can be used to quickly transfer the sewage and dirt to the sewage outlet.

When the screw is driven to rotate by the roller brush or when the screw is driven to rotate by the motor, on the one hand, the screw rotates around its own axis, and on the other hand, the thread of the screw rolls along the inner surface of the sewage tank, thus forming a sealed chamber similar to a pump. , every time the screw rotates one revolution, the liquid or dirt in the sealing cavity pushes forward by one pitch. With the continuous rotation of the screw, the water and dirt removed by the thread from the roller brush are compressed from a sealing cavity through spiral transmission. To another sealed cavity, and finally squeeze out of the sewage tank and enter the sewage outlet, a certain adsorption pressure will be formed during work, which is conducive to transmission. The sealed cavity here does not specifically refer to a completely sealed state, but is just a visual expression.

The cleaning module of this patent has the advantages of simple structure, safe and reliable operation, and convenient use and maintenance. Since the vacuum cleaner module is cancelled, it does not require a large-capacity battery to support the work. It has a long working life and low working noise. The product structure is simple and the product can do To be lightweight enough to help users move the product.

The screw assembly can be passively rotated or actively rotated. When passively rotating, the rotation of the roller brush assembly drives the screw assembly to passively rotate; at this time, the threaded edge of the screw assembly is set close to the inner wall of the dirt collecting tank but does not come into contact. Avoid excessive resistance, which may cause it to get stuck. If the screw assembly adopts an active rotation mode, the screw assembly will be connected to the motor and actively rotate. The threaded edge of the screw assembly and the inner wall of the dirt collecting tank can be set close to each other, or set close to, or in contact with each other, although there will be a certain amount of friction. resistance, but the screw drive motor can overcome the relevant resistance.

The screw body of the screw assembly is provided with a first thread group and a second thread group. The thread diameter of the second thread group is larger than the thread diameter of the first thread group. The thread pitch of the second thread group is smaller than the first thread group. The thread spacing of the group, the second thread group and the sewage outlet are arranged correspondingly, the first thread group and the second thread group are flexible thread groups, the length of the first thread group is greater than the second thread group, and the thread group is The roller brush drives the rotation, and the thread group and the dirt collecting tank are designed close to each other. The design of this structural combination is more conducive to the formation of negative pressure, and is more conducive to the relative movement between the screw, the dirt collecting tank and the roller brush in the dirt collecting tank cavity. A certain negative pressure suction effect is formed in the body, but no vacuum cleaner related mechanisms are needed.

Compared with the existing technology, the technical solution of this patent adopts a brand-new cleaning principle, which has good floor cleaning effect and can realize real-time self-cleaning by rubbing; it has low energy consumption and low noise. The solution is ingeniously designed, modularized and easy to disassemble. Compared with replacing core components, the cleaning effect is good, the cost is low, and the product is reliable and long-lasting.

The thread group of the screw body 401 is in extrusion contact with the roller brush surface, and the thread group is in extrusion contact with the roller brush surface and rotates. On the one hand, the sewage and dirt on the roller brush surface can be scraped or squeezed out; The sewage and dirt are transferred to one end through the rotation of the screw in the semi-enclosed sewage tank; on the other hand, when the screw and the roller brush surface are in working condition, they maintain real-time rubbing action, thereby realizing the real-time rubbing and self-cleaning function while working; At the same time, since there is no need for a vacuum cleaner, it has low energy consumption and low noise.

The passive working mode of the screw assembly 400 is lower in cost and the structural design is simpler.

The gap between the threaded edge of the screw assembly 400 in this patent and the inner wall of the dirt collecting groove 204 is less than 5 mm, preferably less than 1 mm, and more preferably 0.2-0.5 mm. If the gap between the thread edge and the inner wall of the dirt collecting groove 204 is too large, the screw rotation will not be effective in transmitting dirt. Cut or contact will increase friction and affect transmission.

When in use, one end of the first conveying channel 911 away from the second conveying channel 912 is close to the bottom of the liquid in the first accommodation chamber, so as to facilitate the first The delivery channel fully delivers the liquid in the second accommodation chamber 703 . Of course, the first conveying channel 911 may also be a hose, so that during use, the end of the first conveying channel 911 away from the second conveying channel 912 naturally hangs down to or is close to the bottom of the liquid in the first accommodation chamber.

Furthermore, the conveyor cover 913 is of split design. The conveyor cover 913 also includes a matching cover 915. The conveyor cover 913 is detachably installed on the matching cover 915. In the example, the conveying cover 913 is buckled on the matching cover 915. On the other hand, the connection cover 914 is connected to the matching cover 915 .

All technical features of all the above components can be freely combined without conflict, and their free combination or simple variations, changes and modifications are within the scope of protection of this patent.

Compared with the existing technology, the technical solution described in this patent has at least one or more of the following beneficial effects.

The floor brush bracket body 203 is preferably made of an integrally stretched aluminum support frame to firmly support the entire equipment. If a plastic support frame is used for support, it needs to be thicker, making the equipment relatively bulky. If special plastic is used, The cost may increase and the structure may become complicated. In addition, the assembled structure is unstable and easily damaged.

A combination of a screw assembly and a dirt collecting tank is provided. The screw assembly squeezes the surface of the roller brush and rotates in reverse with the roller brush. Compared with the technical solution in the prior art that uses a wiper strip to scrape the roller brush to remove water and dirt, when the thread When the roller brush is squeezed, the sewage and dirt on the roller brush can be squeezed out, which is beneficial to the self-cleaning and automatic squeezing of the roller brush.

The screw body of the screw assembly 400 is provided with a first thread group 402 and a second thread group 403. The thread diameter of the second thread group 403 is larger than the thread diameter of the first thread group 402. The second thread group 403 has a thread diameter greater than that of the first thread group 402. The thread pitch is smaller than the thread pitch of the first thread group 402, and the second thread group is provided correspondingly to the sewage outlet 212; switching between thread groups with different thread pitches can increase the transmission force and centrifugal force generated by the spiral in the area close to the sewage outlet 212. Increasing the transmission pressure is more conducive to the transmission of sewage and dirt to the sewage tank. Switching thread groups with different diameters can also increase the transmission force and centrifugal force generated by the spiral in the sewage outlet 212 area, and increase the transmission pressure.

The floor brush flip cover 600 is provided with a pressure roller 605 to further squeeze the roller brush to remove water, block large particles of dirt, and avoid residual water marks and dirt on the floor after cleaning by the roller brush.

The floor brush bracket is provided with a sewage holding tank 204. The sewage, clean water and dirt are cooperated with the screw assembly and the sewage holding tank to form a sewage and dirt drainage channel, which is led out through the sewage and dirt drainage port, which solves the problem of inefficiency in the existing technology. The problem of water and pollution removal. The angle of the semi-enclosed structure of the dirt collecting tank 204 is preferably between 180 degrees and 270 degrees. This arrangement enables the dirt collecting tank 204 to use the roller brush surface to form a relatively closed cavity, which is more conducive to the rotation transmission of the screw assembly. The sewage and/or granular dirt on the brush will fall into the sewage tank to prevent the sewage and/or granular dirt from overflowing.

After the floor cleaning device completes cleaning the floor, it can also use clean water to mop the floor for a while. At this time, the floor is relatively clean. The roller brush basically completes the self-cleaning work under the rubbing action of the clean water and the screw assembly. Roller brushes are less likely to produce odors.

Although floor scrubbers in the prior art claim to have wet and dry sweeping and mopping functions, their working principle generally uses a scraper to scrape water stains on the roller brush. In fact, they cannot achieve a "drying" effect without water stains, and cannot It can effectively remove dirt and sewage, and products with this function are expensive, have complicated structural designs, and are easily damaged; or use a vacuum cleaner with high suction power to suck up water stains, but it is noisy and the product price is high. If the wiper blade of such products exerts a large pressure on the roller brush and wipes excessively, it will form a great resistance and damage the roller brush body. Moreover, no matter how much pressure the wiper blade exerts on the roller brush, it will not be able to fully remove the water. Water removes dirt, because the wiper blade and the roller brush body are in contact with one moving and one static surface, the friction resistance is large, and the extrusion efficiency is low, it is easy to damage the scraper and the roller brush, and generates great resistance to the roller brush. On the contrary, if the applied pressure is small, the sewage on the brush roller body cannot be effectively removed, making the brush roller body easy to form water stains on the ground.

In this patent, on the one hand, the flexible thread group of the screw assembly and the roller brush surface are used for rotation and extrusion. The screw assembly and the roller brush assembly are two cylinders that rotate relative to each other. The resistance is small, the extrusion effect is good, and more It is conducive to squeezing water, removing or scraping off dirt, and forming a self-cleaning effect by rubbing. At the same time, the thread group of the screw assembly is cleverly used to rotate to form a sewage and dirt transport channel, which is more conducive to the export of sewage and/or granular dirt. The cleaning equipment is also equipped with a clean water tank and a water pump, which transport clean water to one end of the screw assembly or the surface of the roller brush body, so that the roller brush body further forms a self-cleaning function, which is more conducive to the overall product of this patent without the need for assistance like other products on the market. Only in this way can the equipment realize the cleaning function, thus realizing the true self-cleaning function.

The drive motor mechanism of the roller brush is built into the roller brush body. It has a compact structure and saves space. It can reduce the size of components and equipment, making the equipment lighter, more portable and simpler, and at the same time saving production costs.

When the roller brush assembly is disassembled from the self-cleaning equipment, the drive motor mechanism of the roller brush is disassembled together with the roller brush. It is simple to operate and easy to use. It also avoids the sewage and/or granular dirt on the roller brush from falling and impregnating the drive structure. Causes a short circuit in the drive structure, thereby damaging the drive structure. The driving structure in the roller brush is electrically connected to the roller brush handle installation grooves on the left and right covers of the floor brush bracket. The structure is simple, the installation is convenient, and the design is clever, making the disassembly and installation of the roller brush assembly very convenient.

A heat dissipation structure is provided in the roller core of the roller brush assembly 300, and the heat generated by the transmission gearbox motor 303 can be discharged through the heat dissipation channel, thereby cooling the motor, thus preventing the motor from being burned due to excessive temperature. The motor assembly composed of the transmission gearbox motor 303 is all wrapped in an aluminum shell, which is waterproof on the one hand and conducive to heat dissipation on the other.

In actual use, roller brushes often need to be replaced. The integrated installation and disassembly of roller brush components brings a good user experience to users when replacing roller brushes.

The sewage tank is buckled or fixed on the fixing part of the floor brush module for easy installation; a disassembly button is provided, and pulling the disassembly button makes it easier to remove the sewage tank, which is convenient for pouring out sewage and cleaning the sewage tank. It is easy to disassemble, especially for women who use it a lot and have little strength, making it easier and more convenient to operate.

Set up a clean water tank. While the roller brush is cleaning sewage and dirt, you can use clean water to clean the roller brush to realize the self-cleaning function of the roller brush and help the floor to be cleaned better and cleaner. At the same time, a sliding buckle structure is provided on the operating lever body, so that clean water tanks of different sizes can be installed as needed, improving the freedom and flexibility of the equipment.

The invention is provided with a roller brush detection structure, which can detect whether there is water on the roller brush, prevent the hard collodion roller brush from being unable to clean the ground, and make the cleaning device more intelligent. After the cleaning device is started, the roller brush detection structure first detects whether there is water on the roller brush. If there is water, it means that the collodion roller brush is in a soft state and can directly clean the floor. If there is no water on the roller brush, it means that the collodion roller brush is in a dry state. The control module controls the first water pump to send water to the collodion roller brush. If the roller brush detection structure detects that there is water on the collodion roller brush, the first water pump stops. Send water to the collodion roller brush, and the cleaning device starts the cleaning operation. During the cleaning process of the cleaning device, the control module controls the second water pump to deliver water to the sewage tank where the screw assembly is installed. The screw assembly installed in the sewage tank squeezes the collodion roller brush and rotates to transport water and dirt, which can both It plays the role of squeezing and cleaning roller brushes, and can also transport and clean sewage and dirt.

The screw assembly and the roller brush assembly are arranged in pressing contact. During the rotation of the roller brush assembly and the screw assembly, a negative pressure area is formed in the dirt holding tank. The screw assembly squeezes out the water and dirt on the collodion roller brush of the roller brush assembly. Press into the dirt tank. Since the thread group on the screw assembly has a rotation direction and the screw assembly cooperates with the sewage tank, the screw assembly will drive the water, dirt and gas in the sewage tank to be transported to the sewage outlet of the sewage tank, and then pass through the second thread group at high speed. Rotate and throw it into the sewage tank. When the water, dirt and gas in the sewage tank are transported to the sewage outlet, a negative pressure is formed in the sewage tank, and the water, dirt and air cleaned by the rolling brush assembly will be replenished into the negative pressure area, and the cycle will continue. After sewage dirt and gas enter the sewage tank, they will occupy the volume in the sewage tank. The air in the sewage tank needs to be discharged to facilitate the continuous entry of sewage dirt and gas into the sewage tank. Therefore, open a ventilation hole in the sewage tank shell. If the gas pressure in the sewage tank cannot be released, the water, dirt and gas in the sewage tank cannot continue to enter the sewage tank, causing water leakage in the cleaning equipment.

A ventilation hole is provided on the sewage tank. After the water, dirt and gas in the sewage tank enter the sewage tank, the gas in the sewage tank is discharged through the ventilation hole to balance the air pressure inside and outside the sewage tank.

A blocking groove is provided on the inner wall of the sewage tank to block the ventilation holes and sewage dirt to prevent the ventilation holes from being blocked by sewage dirt surged in the sewage tank or sewage dirt thrown into the sewage tank from the water inlet of the sewage tank. , causing the gas in the sewage tank to be unable to be discharged, the air pressure in the sewage tank to be unable to be released, or sewage dirt to overflow from the ventilation holes. Water-blocking cotton is installed in the shielding tank to prevent surges better and prevent dirt from overflowing from the ventilation holes. It also prevents external foreign objects from falling into the sewage tank from the ventilation holes.

The roller brush assembly is sleeved on the motor assembly. The motor assembly drives the roller brush assembly to rotate through the rotating joint and the installation groove. The motor assembly is fixedly installed on the main body of the equipment. When the roller brush assembly is disassembled, the motor assembly is not disassembled together with the roller brush assembly, making the structure Simple design, convenient disassembly and assembly, and easy operation. The rotating joint is provided with a protruding strip that meshes with the installation groove. The angle between the length direction of the protruding strip and the length direction of the roller brush assembly is less than 90 degrees. The protruding strip is along the end of the protruding strip close to the driving motor to the protruding strip. In the direction away from one end of the driving motor, the protrusions are inclined toward the direction of rotation of the roller brush assembly when it moves forward, so that when the cleaning device is used, the roller brush assembly rotates forward, and when the roller brush body rotates, there is a force in the direction of the motor assembly, so that When the roller brush body rotates, it is more tightly sleeved on the motor assembly to ensure that the roller brush assembly will not loosen from the equipment main body when the equipment is in use. At the same time, the end of the roller brush component away from the motor component can be magnetically attached to the main body of the device. It is easy to disassemble and install, and saves effort. It is especially suitable for use by weak female users.

There are very few existing two-in-one water tanks, and the water tanks are getting bigger and bigger. If they are too big, it will be inconvenient for everyone to use. This patent uses a unique partition to reduce the volume of the water tank as much as possible and save space. When the water tank and the cleaning module are placed horizontally, the sewage outlet of the sewage chamber is connected to the sewage outlet of the cleaning module. The sewage outlet of the sewage chamber is set on the side wall of the sewage chamber. In this way, when collecting sewage dirt, the sewage chamber can only use less than one sewage outlet. The volume space above the sewage outlet is wasted. Or the sewage outlet is specially designed to be placed at the upper part of the sewage chamber to make full use of the volume of the sewage chamber. Otherwise, if the screw assembly is used to throw out the sewage dirt, the lift can only be half due to the natural throwing force. Space is wasted. In view of the above situation, a unique partition is used to set the space above the sewage chamber as a clean water chamber. The advantage of this arrangement is that we do not need to design a complex sewage discharge structure. We can only use the natural lift of the screw assembly to throw the sewage dirt into the clean water chamber. to the sewage chamber. In addition, the upper part of the sewage chamber divides the water tank into two parts through a unique curved or inclined partition into a clean water chamber (i.e., the second accommodation chamber) and a sewage chamber (i.e., the first accommodation chamber). The clean water chamber can be directly connected to the main body of the equipment. The clean water pipe in the clean water chamber is very short, making the structure of the entire cleaning equipment simpler. Of course, the water in the clean water chamber is sucked through the suction device to supply water to the surface of the roller brush. Through the above design, the ingenuity of this equipment is that the cleaning module throws sewage dirt into the sewage chamber through the lift driven by the screw assembly. No additional drive is needed. However, due to the limited natural lift, the height of the sewage outlet and sewage outlet is low. Therefore, a unique partition is used to divide the upper part of the sewage chamber into a clean water chamber to fully utilize the volume of the water tank. unique clear The function of the cleaning module and the unique partition isolation of the water tank enable the water tank to be fully utilized.

If the two-in-one water tank of this patent is matched with other similar vacuum cleaners or floor scrubbers, it is not as good as the water tank of this patent and the cleaning module with a screw assembly. The cleaning module of this patent only needs to drive the driving part of the roller brush. That is, the screw assembly in close contact with the roller brush can rotate with the roller brush. The rotation of the screw assembly can drive the sewage and dirt to be transported to the sewage outlet, and the rotation of the screw assembly generates centrifugal force. Under the action of the centrifugal force, a lift is generated, and the sewage and dirt pass through. The lift is thrown into the sewage chamber. This sewage discharge method is extremely simple, cost-saving, simple and efficient, and makes full use of the internal space of the water tank through the unique partition design. The combination of the above characteristics, the screw assembly sewage discharge method and the water tank design method, compared with The existing technology constitutes an obvious innovation and produces unexpected effects, further reducing the complexity of the cleaning equipment structure, while maintaining cleaning efficiency, reducing product costs, and improving user experience.

The water tank is further preferably designed to be cup-shaped, and the ports of the sewage cover assembly and the clean water cover assembly are therefore designed to be circular. Circular sealing rings can be used to seal the sewage cover assembly and the clean water cover assembly. The circular sealing rings are sealed relative to sealing rings of other shapes. The effect is better and the service life is longer. At the same time, the circular sealing ring is cheaper than other shapes of sealing rings. The water tank adopts a cup-shaped design, which facilitates the opening of the sewage cover assembly and the clean water cover assembly, cleaning the sewage chamber and replenishing clean water into the clean water chamber. At the same time, a filter element is provided in the sewage chamber to accommodate dirt, thereby separating the sewage and dirt in the sewage chamber.
