Description

Technical Field

[0001] This utility model relates to the field of floor scrubber technology, specifically to a floor scrubber roller brush water spraying structure. Background Technology

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

[0003] For example, Chinese patent with publication number CN113229742A, patent name: A vacuum cleaner roller brush structure and vacuum cleaner floor brush, and publication date: 2021-08-10, includes a roller brush body and a cleaning part. The cleaning part covers the outside of the roller brush body and is made of PVA material. PVA material has strong water absorption. The roller brush in the vacuum cleaner floor brush adopts the above structure. The roller brush cleans the floor with water stains and achieves the effect of quick-drying the floor.

[0004] The existing technology has the following technical problems: In order to facilitate the spraying of water onto the roller brush, the existing floor brush sets the water tank inside the roller brush. However, when the roller brush rotates, it needs to drive the water tank to rotate synchronously. Since the water tank has a certain weight when it is full of water, the roller brush needs to provide more power to drive the water tank to rotate, which increases the overall energy consumption of the floor scrubber.

[0005] Therefore, we propose a floor scrubber roller brush water spraying structure to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this utility model is to provide a water spraying structure for a floor scrubber roller brush, in order to solve the problem mentioned in the background art that existing floor brushes on the market, in order to facilitate the spraying of water onto the roller brush, place the 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 when it is full of water, the roller brush needs to provide more power to drive the water cylinder to rotate, thereby increasing the overall energy consumption of the floor scrubber.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a floor scrubber roller brush spraying structure, including a front water tank and a rear water tank, and two roller brush bodies for accommodating the front and rear water tanks. The roller brush bodies are mounted on the main body of the floor scrubber. Movable support components are installed on both the front and rear water tanks. The end of the front water tank is provided with an inlet and an outlet pipe for connecting to the water inlet and outlet of the main body of the floor scrubber. The end of the rear water tank is provided with a guide pipe that connects to the inlet pipe of the front water tank to form a water circuit communication system.

[0008] Preferably, the sides of the front and rear water tanks are provided with positioning buckles that can be detached from the main body of the floor scrubber via elastic buckles.

[0009] By adopting the above technical solution, the positioning buckles on the front and rear water tanks make it easy to assemble and disassemble the front and rear water tanks on the main body of the floor scrubber.

[0010] Preferably, the movable support component includes a connecting bearing installed at one end of the front water tank and the rear water tank, the connecting bearing being connected to a top column fixed inside the roller brush body, and a movable sealing collar assembled with the roller brush body at the other end of the front water tank and the rear water tank.

[0011] By adopting the above technical solution and by setting up the movable support components, it is possible to avoid driving the front water tank and the rear water tank to rotate synchronously when the roller brush body rotates.

[0012] Preferably, the movable sealing rings on the front water tank and the rear water tank are rotatably connected, and a rubber sealing ring is fitted on the movable sealing ring. After the roller brush body rotates, the top column inside it abuts against 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.

[0013] By adopting the above technical solution, the rotation of the movable sealing ring on the front or rear water tank enables only the movable sealing ring to rotate when the roller brush body rotates.

[0014] Preferably, the rear water tank is equipped with a detection float, and a sensor for detecting the float's movement is installed on the rear water tank. The sensor is electrically connected to the floor scrubber base station.

[0015] By adopting the above technical solution, when the sensor detects that the float has moved into position, it can transmit an electrical signal to the floor scrubber base station, and control the base station water pump to shut down through the floor scrubber base station.

[0016] Preferably, one end of the detection float is equipped with a pin, and the detection float forms a rotating connection structure with the interior of the rear water tank through the pin. As the water volume inside the rear water tank increases, the detection float inside the rear water tank can rotate around the pin 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 to the correct position, the sensor feeds back an electrical signal to the floor scrubber base station, causing the base station water pump on the floor scrubber base station to stop working.

[0017] 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.

[0018] Preferably, the rear water tank is equipped with an air vent for removing internal air. Because the rear water tank has an air vent, the water level in the rear water tank decreases first. Only when the water level in the rear water tank is insufficient does the water level in the front water tank begin to decrease. This draws out clean water from both the front and rear water tanks and sprays it onto the roller brush body to facilitate subsequent cleaning of the ground. This allows the water source inside the front roller brush to provide downward pressure to the roller brush body for the longest possible time, increasing the cleaning effect of the roller brush body.

[0019] By adopting the above technical solution, the air inside the rear water tank can be squeezed out during water filling by setting the vent and waterproof port.

[0020] Preferably, the bottom of the main body of the floor scrubber is equipped with a water inlet that is connected to the water inlet of the base station on the floor scrubber base station.

[0021] By adopting the above technical solution, the water inlet on the main body of the floor scrubber is connected to the water inlet of the base station, which facilitates the injection of water into the front and rear water tanks on the main body of the floor scrubber by the base station water pump.

[0022] Another technical solution provided by this utility model is a water spraying method for a floor scrubber roller brush water spraying structure, including the following steps:

[0023] Step 1: Connect the water inlet at the bottom of the floor scrubber to the water inlet on the base station of the floor scrubber. The water pump of the base station first fills 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, the water enters the rear water tank after the front water tank is filled until the rear water tank is full.

[0024] Step 2: As the rear water tank fills up, the detection float inside rotates upward under the buoyancy of the water flow. After the sensor on the rear water tank detects the change in the position of the detection float, the sensor sends an electrical signal back to the floor scrubber base station, causing the base station water pump on the floor scrubber base station to stop working, and the water filling is completed.

[0025] Step 3: The floor scrubber uses a water pump inside the main body to draw clean water. Since the front and rear water tanks are connected, and the rear water tank has an air vent, the water level in the rear water tank decreases first. Only when the water level in the rear water tank is insufficient does the water level in the front water tank begin to decrease. This draws clean water from both the front and rear water tanks and sprays it onto the roller brush for subsequent cleaning of the floor.

[0026] Compared with the prior art, the beneficial effects of this utility model are: the water spray structure of the floor scrubber roller brush can, through the movable connection between the water tube and the roller brush, prevent the water tube from rotating synchronously with the roller brush when it rotates. The water source inside the water tube can increase the downward pressure of the roller brush to a certain extent and improve the cleaning effect of the roller brush.

[0027] 1. Equipped with a connecting bearing and a movable sealing ring, the top column inside the roller brush body abuts against the connecting bearing after rotation. 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.

[0028] 2. Equipped with a detection float, as the water volume inside the rear water tank increases, the detection float inside the rear water tank rotates around the pin 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 to the correct position, the sensor feeds back an electrical signal to the floor scrubber base station, causing the base station water pump on the floor scrubber base station to stop working.

[0029] 3. Equipped with an air vent and waterproof vent, the water level in the rear water tank decreases first. Only when the water level in the rear water tank is insufficient does the water level in the front water tank begin to decrease. This draws out clean water from both the front and rear water tanks and sprays it onto the roller brush body to facilitate subsequent cleaning of the ground. This allows the water source inside the front roller brush to provide maximum downward pressure to the roller brush body for the longest time, increasing the cleaning effect of the roller brush body.

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1: Please refer to Figures 1-7 Existing floor scrubbers, in order to facilitate water spraying onto the roller brush, place the water tank inside the roller brush. However, when the roller brush rotates, it needs to drive the water tank to rotate synchronously. Since the water tank has a certain weight when full of water, the roller brush needs to provide more power to drive the water tank to rotate, thus increasing the overall energy consumption of the floor scrubber. To solve this technical problem, this embodiment discloses the following technical content: a roller brush water spraying structure for a floor scrubber, including a front water tank 1 and a rear water tank 2, and two roller brush bodies 3 for accommodating the front water tank 1 and the rear water tank 2. The roller brush bodies 3 are mounted on the main body 4 of the floor scrubber. Both the front water tank 1 and the rear water tank 2 are equipped with movable support components. The end of the front water tank 1 is provided with a water inlet 9 and a water outlet 10 for connecting to the water inlet and water outlet of the main body 4 of the floor scrubber. The end of the rear water tank 2... The unit is equipped with a guide pipe 11 that connects with the water inlet 9 on the front water tank 1 to form a water circuit connection system. The sides of the front water tank 1 and the rear water tank 2 are equipped with positioning buckles 5 that are detachable and can be attached to the main body 4 of the floor scrubber with elastic buckles. The movable support components include connecting bearings 6 installed at one end of the front water tank 1 and the rear water tank 2, the connecting bearings 6 being connected to the top column 8 fixed inside the roller brush body 3, and movable sealing sleeves 7 that are assembled with the roller brush body 3 at the other end of the front water tank 1 and the rear water tank 2. The movable sealing sleeves 7 on the front water tank 1 and the rear water tank 2 are rotatably connected, and rubber sealing rings are fitted on the movable sealing sleeves 7. The rear water tank 2 is equipped with an exhaust and waterproof port 13 for venting internal air. The bottom of the main body 4 of the floor scrubber is equipped with a water inlet that connects to the base station docking water inlet 16 on the base station 15 of the floor scrubber.

[0040] Because both the front water tank 1 and the rear water tank 2 are equipped with a connecting bearing 6 and a movable sealing ring 7, when the roller brush body 3 rotates, the internal top column 8 abuts against the connecting bearing 6. Therefore, when the roller brush body 3 rotates, it can only make the connecting bearing 6 and the movable sealing ring 7 rotate on the front water tank 1 and the rear water tank 2, and will not drive the front water tank 1 and the rear water tank 2 to rotate synchronously. Connect the water inlet at the bottom of the floor scrubber body 4 to the base station docking water inlet 16 on the floor scrubber base station 15. Water is first injected into the front water tank 1 inside the front roller brush body 3 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 interconnected, after the front water tank 1 is filled with water, it enters the interior of the rear water tank 2 until the rear water tank 2 is full.

[0041] Example 2: The technical content disclosed in this example is a further improvement based on Example 1 above. The following technical content is disclosed in this example: a detection float 12 is configured 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 is installed at one end of the detection float 12, and the detection float 12 and the interior of the rear water tank 2 form a rotating connection structure through the pin.

[0042] As the water volume inside the rear water tank 2 increases, the detection float 12 inside the rear water tank 2 rotates around the pin at its end under the action of buoyancy. 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 position, 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.

[0043] Example 3: The technical content disclosed in this example is a further improvement based on Examples 1 and 2 above. This example discloses a water spraying method for the roller brush water spraying structure of a floor scrubber, the specific content of which is as follows:

[0044] Connect the water inlet at the bottom of the main body 4 of the floor scrubber to the base station docking inlet 16 on the base station 15 of the floor scrubber. Water is first pumped into the front water tank 1 inside the front roller brush 3 by the base station water pump. Since the front water tank 1 and the rear water tank 2 inside the rear roller brush 3 are interconnected, water flows from the front water tank 1 into the rear water tank 2 until the rear water tank 2 is full. As the rear water tank 2 fills up, the detection float 12 inside rotates upwards under the buoyancy of the water flow. The sensor 14 on the rear water tank 2 senses the change in the position of the detection float 12. 14 The electrical signal is fed back to the floor scrubber base station 15, causing the base station water pump on the floor scrubber base station 15 to stop working. After the water filling is completed, the floor scrubber body 4 draws clean water through the floor brush water pump. Since the front water tank 1 and the rear water tank 2 are connected to each other, and the rear water tank 2 is equipped with an exhaust and waterproof port 13, the water volume in the rear water tank 2 decreases first. When the water volume in the rear water tank 2 is insufficient, the water volume in the front water tank 1 begins to decrease. Thus, the clean water in the front water tank 1 and the rear water tank 2 is drawn out and sprayed onto the roller brush body 3 to facilitate subsequent cleaning of the floor.

[0045] This utility model discloses a water spraying structure for a floor scrubber's roller brush, which has the following beneficial effects:

[0046] Equipped with a connecting bearing 6 and a movable sealing ring 7, the top column 8 inside the roller brush body 3 abuts against the connecting bearing 6 after rotation. Therefore, when the roller brush body 3 rotates, it can only make the connecting bearing 6 and the movable sealing ring 7 rotate on the front water tank 1 and the rear water tank 2, and will not drive the front water tank 1 and the rear water tank 2 to rotate synchronously.

[0047] The rear water tank 2 is equipped with a detection float 12. As the water volume inside the rear water tank 2 increases, the detection float 12 inside the rear water tank 2 can rotate around the pin at the end under the action of buoyancy. 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 to the correct position, 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.

[0048] The rear water tank 2 is equipped with an exhaust and waterproof vent 13. Because the rear water tank 2 is equipped with an exhaust and waterproof vent 13, the water volume in the rear water tank 2 decreases first. When the water volume in the rear water tank 2 is insufficient, the water volume in the front water tank 2 begins to decrease. This draws out the clean water from the front water tank 1 and the rear water tank 2 and sprays it onto the roller brush body 3 to facilitate subsequent cleaning of the ground. This allows the water source inside the front roller brush to provide downward pressure to the roller brush body 3 for the longest time, thereby increasing the cleaning effect of the roller brush body 3.
