Description

Technical Field

[0001] The invention relates to the technical field of floor scrubbers, and in particular to a roller brush water spraying structure and a water spraying method of a floor scrubber. Background Art

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors, sucking out dirty water, and taking the dirty water away from the site. In order to reduce the size of the equipment and improve the integration of the equipment, some floor scrubbers usually have a water spray structure inside the roller brush, which makes it easier to spray water on the surface of the roller brush and achieve effective cleaning of the floor.

[0003] For example, the Chinese patent with publication number: CN113229742A, patent name: A vacuum cleaner roller brush structure and vacuum cleaner floor brush, publication date: 2021-08-10, includes a roller brush body and a cleaning part, the cleaning part is coated on the outside of the roller brush body, the cleaning part is made of PVA material, the PVA material has strong water absorption, the roller brush in the vacuum cleaner floor brush adopts the above structure, the roller brush cleans the ground with water stains, and achieves the effect of quick drying the ground; The above-mentioned prior art has the following technical problems: in order to facilitate the spraying of water onto the roller brush, the existing floor brush sets a water cylinder inside the roller brush. However, when the roller brush rotates, it needs to drive the water cylinder to rotate synchronously. Since the water cylinder has a certain weight after being filled with water, the roller brush needs to provide greater power when driving the water cylinder to rotate, thereby increasing the overall energy consumption of the floor scrubber.

[0004] Therefore, we propose a floor scrubber roller brush water spraying structure and a water spraying method thereof to solve the above-mentioned problems. Summary of the invention

[0005] The object of the present invention is to provide a water spraying structure and a water spraying method for a roller brush of a floor scrubber, so as to solve the problem raised in the above background technology that the existing floor brushes on the market currently have a water cylinder arranged inside the roller brush in order to facilitate spraying water on the roller brush. However, when the roller brush rotates, it is necessary to drive the water cylinder to rotate synchronously. Since the water cylinder has a certain weight after being filled with water, the roller brush needs to provide greater power when driving the water cylinder to rotate, thereby increasing the overall energy consumption of the floor scrubber.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a roller brush water spray structure for a floor scrubber, comprising a front water tank and a rear water tank, and two front and rear roller brush bodies for accommodating the front water tank and the rear water tank, the roller brush body being mounted on a floor scrubber body, the front water tank and the rear water tank being both provided with movable supporting components, the end of the front water tank being provided with a water inlet pipe opening and a water outlet pipe opening for interconnecting with a water injection interface and a water pumping interface of the floor scrubber body, the end of the rear water tank being provided with a guide pipe opening for docking with the water inlet pipe opening on the front water tank to form a water path connection system.

[0007] Preferably, the sides of the front water tank and the rear water tank are provided with positioning buckles which can be detachably assembled with elastic buckles on the main body of the floor scrubber.

[0008] By adopting the above technical solution, the front water tank and the rear water tank can be easily disassembled and assembled on the main body of the floor scrubber through the positioning buckles on the front water tank and the rear water tank.

[0009] Preferably, the movable supporting component includes a connecting bearing installed at one end of the front water tank and the rear water tank, the connecting bearing is interconnected with a top column fixed inside the roller brush body, and a movable sealing ring assembled with the roller brush body at the other end of the front water tank and the rear water tank.

[0010] By adopting the above technical solution and providing the movable supporting component, it is possible to avoid driving the front water tank and the rear water tank to rotate synchronously when the roller brush body rotates.

[0011] Preferably, the movable sealing rings on the front water tank and the rear water tank are both rotatably connected, and a rubber sealing ring is sleeved on the movable sealing ring. After the roller brush body rotates, the top column inside it conflicts with the connecting bearing. Therefore, when the roller brush body rotates, it can only make the connecting bearing and the sealing ring rotate on the front water tank and the rear water tank, and will not drive the front water tank 1 and the rear water tank to rotate synchronously.

[0012] By adopting the above technical solution, the movable sealing ring is rotated on the front water tank or the rear water tank, so that when the roller brush body rotates, only the movable sealing ring is driven to rotate.

[0013] Preferably, a detection float is disposed inside the rear water tank, and a sensor for detecting the floating of the float is installed on the rear water tank, and the sensor is electrically connected to the floor scrubber base station.

[0014] By adopting the above technical solution, when the sensor senses that the detection float has floated into place, it can transmit an electrical signal to the floor scrubber base station, and control the base station water pump to be turned off through the floor scrubber base station.

[0015] Preferably, a pin shaft is installed at one end of the detection float, and the detection float forms a rotating connection structure with the interior of the rear water tank through the pin shaft. The increase in the amount of water inside the rear water tank can cause the detection float inside the rear water tank to rotate around the pin shaft at the end under the action of buoyancy, and the position of the detection float is detected by the sensor on the rear water tank. When the detection float moves into place, the sensor feeds back to the floor scrubber base station through an electrical signal, causing the base station water pump on the floor scrubber base station to stop working.

[0016] By adopting the above technical solution, when the water level inside the rear water tank increases, the detection float can be pushed to rotate upward around the pin shaft under the action of buoyancy.

[0017] Preferably, the rear water tank is equipped with an exhaust waterproof port for exhausting internal air. Because the rear water tank is provided with the exhaust waterproof port, the amount of water in the rear water tank is reduced first until the water amount in the rear water tank is insufficient, and then the amount of water in the front water tank begins to reduce, thereby pumping out the clean water in the front water tank and the rear water tank and spraying it onto the roller brush body to facilitate subsequent cleaning of the ground, so that the water source inside the front roller brush can provide downward pressure on the roller brush body for the longest time, thereby increasing the cleaning effect of the tube roller brush body.

[0018] By adopting the above technical solution, the exhaust waterproof port is provided so that the air inside the rear water tank can be squeezed out when the rear water tank is filled with water.

[0019] Preferably, a water inlet is provided at the bottom of the floor scrubber body and is interconnected with a base station docking water inlet on the floor scrubber base station.

[0020] By adopting the above technical solution, through the mutual connection of the water inlet on the floor scrubber body and the water inlet of the base station, it is convenient to inject water into the front water tank and the rear water tank on the floor scrubber body through the water pump of the base station.

[0021] Another technical solution provided by the present invention is to provide a water spraying method of a roller brush water spraying structure of a floor scrubber, comprising the following steps: Step 1: Connect the water inlet at the bottom of the floor scrubber body to the base station docking water inlet on the floor scrubber base station. Use the base station water pump to fill water into the front water tank inside the front roller brush body. Since the front water tank and the rear water tank inside the rear roller brush body are connected to each other, the water in the front water tank enters the rear water tank after the water is filled until the rear water tank is full. Step 2: As the water inside the rear water tank is full, the detection float inside it rotates upward under the action of the buoyancy of the water flow. After the sensor on the rear water tank senses the position change of the detection float, the sensor feeds back to the floor scrubber base station through an electrical signal, causing the base station water pump on the floor scrubber base station to stop working, and the water filling is completed; Step 3: Draw clean water through the floor brush water pump inside the main body of the floor scrubber. Since the front water tank and the rear water tank are interconnected and an exhaust and waterproof port is provided on the rear water tank, the amount of water in the rear water tank decreases first until the water in the rear water tank is insufficient. Then the amount of water in the front water tank begins to decrease, thereby drawing out the clean water in the front and rear water tanks and spraying it onto the roller brush body to facilitate subsequent cleaning of the floor.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: the floor scrubber roller brush water spraying structure and the water spraying method thereof can, through the movable connection between the water cylinder and the roller brush during use, enable the water cylinder to not rotate synchronously with the roller brush when the roller brush rotates, and utilize the water source inside the water cylinder to increase the downward pressure of the roller brush to a certain extent, thereby improving the cleaning effect of the roller brush; 1. A connecting bearing and a movable sealing ring are provided. After the roller brush body rotates, the top column inside it conflicts with the connecting bearing. Therefore, when the roller brush body rotates, it can only make the connecting bearing and the sealing ring rotate on the front water tank and the rear water tank, and will not drive the front water tank 1 and the rear water tank to rotate synchronously; 2. A detection float is provided. When the amount of water inside the rear water tank increases, the detection float inside the rear water tank can rotate around the pin shaft at the end under the action of buoyancy. The position of the detection float is detected by the sensor on the rear water tank. When the detection float moves into place, the sensor feeds back the electrical signal to the floor scrubber base station, so that the base station water pump on the floor scrubber base station stops working; 3. An exhaust and waterproof port is provided. Because the rear water tank is provided with an exhaust and waterproof port, the amount of water in the rear water tank is reduced first. When the amount of water in the rear water tank is insufficient, the amount of water in the front water tank begins to reduce, thereby pumping out the clean water in the front and rear water tanks and spraying it onto the roller brush body to facilitate subsequent cleaning of the floor. In this way, the water source inside the front roller brush can provide downward pressure on the roller brush body for the longest time, thereby increasing the cleaning effect of the tube roller brush body.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figure 1-Figure 7 In order to facilitate the spraying of water onto the roller brush, the existing floor brush arranges a water cylinder inside the roller brush. However, when the roller brush rotates, it needs to drive the water cylinder to rotate synchronously. Because the water cylinder has a certain weight after being filled with water, the roller brush needs to provide greater power when driving the water cylinder to rotate, thereby increasing the overall energy consumption of the floor scrubber. In order to solve this technical problem, the present embodiment discloses the following technical content: a roller brush water spraying structure for a floor scrubber, comprising a front water tank 1 and a rear water tank 2, and front and rear roller brush bodies 3 for accommodating the front water tank 1 and the rear water tank 2. The roller brush body 3 is mounted on a main body 4 of the floor scrubber. Both the front water tank 1 and the rear water tank 2 are equipped with movable supporting components. The end of the front water tank 1 is provided with a water inlet pipe 9 and a water outlet pipe 10 for interconnecting with the water injection interface and the water pumping interface of the main body 4 of the floor scrubber. The front water tank 1 and the rear water tank 2 are provided with a guide pipe port 11 which is docked with the water inlet pipe port 9 on the front water tank 1 to form a water communication system. The sides of the front water tank 1 and the rear water tank 2 are provided with positioning buckles 5 which are detachable with the elastic buckles on the washing machine body 4. The movable supporting parts include a connecting bearing 6 installed at one end of the front water tank 1 and the rear water tank 2, the connecting bearing 6 is interconnected with the top column 8 fixed inside the roller brush body 3, and the other end of the front water tank 1 and the rear water tank 2 is assembled with the roller brush body 3. The movable sealing rings 7 on the front water tank 1 and the rear water tank 2 are both rotatably connected, and a rubber sealing ring is sleeved on the movable sealing ring 7. An exhaust waterproof port 13 for removing internal air is installed on the rear water tank 2. The bottom of the washing machine body 4 is provided with a water inlet which is interconnected with the base station docking water inlet 16 on the washing machine base station 15.

[0027] Because the front water tank 1 and the rear water tank 2 are both installed with connecting bearings 6 and movable sealing rings 7 at one end, when the roller brush body 3 rotates, the internal top column 8 conflicts with the connecting bearing 6. Therefore, the roller brush body 3 can only make the connecting bearings 6 and the movable sealing ring 7 rotate on the front water tank 1 and the rear water tank 2 during rotation, and will not drive the front water tank 1 and the rear water tank 2 to rotate synchronously. The water inlet at the bottom of the floor scrubber main body 4 is connected to the base station docking water inlet 16 on the floor scrubber base station 15, and the front water tank 1 inside the front roller brush body 3 is first filled with water through the base station water pump. Because the front water tank 1 and the rear water tank 2 inside the rear roller brush body 3 are connected to each other, the front water tank 1 enters the rear water tank 2 after the water is filled, until the rear water tank 2 is full of water.

[0028] Embodiment 2: The technical contents disclosed in this embodiment are further improvements made on the basis of the above-mentioned embodiment 1. The following technical contents are disclosed in this embodiment: a detection float 12 is arranged inside the rear water tank 2, and a sensor 14 for detecting the floating of the float 12 is installed on the rear water tank 2. The sensor 14 is electrically connected to the floor scrubber base station 15. A pin shaft is installed at one end of the detection float 12, and the detection float 12 forms a rotating connection structure with the interior of the rear water tank 2 through the pin shaft.

[0029] As the amount of water inside the rear water tank 2 increases, the detection float 12 inside the rear water tank 2 can rotate around the pin shaft at the end under the action of buoyancy, and the position of the detection float 12 is detected by the sensor 14 on the rear water tank 2. When the detection float 12 moves into place, the sensor 14 feeds back an electrical signal to the floor scrubber base station 15, causing the base station water pump on the floor scrubber base station 15 to stop working.

[0030] Embodiment 3: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiments 1 and 2. This embodiment discloses a water spraying method of a roller brush water spraying structure of a floor scrubber. The specific contents are as follows: The water inlet at the bottom of the floor scrubber body 4 is connected to the base station docking water inlet 16 on the floor scrubber base station 15, and water is first filled into the front water tank 1 inside the front roller brush body 3 through the base station water pump. Since the front water tank 1 and the rear water tank 2 inside the rear roller brush body 3 are connected to each other, the water in the front water tank 1 enters the rear water tank 2 after the water is filled, until the rear water tank 2 is full of water. As the rear water tank 2 is full of water, the detection float 12 inside it rotates upward under the action of the buoyancy of the water flow, and after the sensor 14 on the rear water tank 2 senses the position change of the detection float 12, the sensor 14 is fed back to the floor scrubber base station 15 through an electrical signal, so that the base station water pump on the floor scrubber base station 15 stops working, the water injection is completed, and clean water is extracted by the floor brush water pump inside the floor scrubber body 4. Since the front water tank 1 and the rear water tank 2 are connected to each other, and the rear water tank 2 is provided with an exhaust waterproof port 13, the water amount in the rear water tank 2 is reduced first, until the water amount in the rear water tank 2 is insufficient, the water amount in the front water tank 1 begins to decrease, so that the clean water in the front water tank 1 and the rear water tank 2 is extracted and sprayed onto the roller brush body 3, so as to facilitate the subsequent cleaning of the floor.

[0031] The present invention discloses a floor scrubber roller brush water spraying structure and a water spraying method thereof, which have the following beneficial effects: A connecting bearing and a movable sealing ring are provided. After the roller brush body rotates, the top column inside it conflicts with the connecting bearing. Therefore, when the roller brush body rotates, it can only make the connecting bearing and the sealing ring rotate on the front water tank and the rear water tank, and will not drive the front water tank 1 and the rear water tank to rotate synchronously. A detection float is provided. When the amount of water inside the rear water tank increases, the detection float inside the rear water tank can rotate around the pin shaft at the end under the action of buoyancy. The position of the detection float is detected by the sensor on the rear water tank. When the detection float moves into place, the sensor feeds back the electric signal to the floor scrubber base station, so that the base station water pump on the floor scrubber base station stops working. An exhaust and waterproof port is provided. Because the rear water tank is provided with an exhaust and waterproof port, the amount of water in the rear water tank decreases first. When the amount of water in the rear water tank is insufficient, the amount of water in the front water tank begins to decrease, thereby pumping out the clean water in the front and rear water tanks and spraying it onto the roller brush body to facilitate subsequent cleaning of the floor. In this way, the water source inside the front roller brush can provide downward pressure on the roller brush body for the longest time, thereby increasing the cleaning effect of the tube roller brush body.
