DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings.

[0021] like Figure 1 to Figure 4 As shown, the embodiment of the present application proposes a dry and wet partitioned floor scrubber, comprising a shell 1, wherein the shell 1 is provided with a working chamber 6 opening toward the ground, wherein a floor brush structure 2 is provided in the working chamber 6; wherein a sewage tank 5, a dust box 4 and a water delivery structure 8 are provided in the shell 1, wherein a first automatic dust suction structure and a second automatic water suction structure are provided between the dust box 4 and the sewage tank 5 and the working chamber 6, respectively; wherein the shell 1 is further provided with a sensor 7 and a controller, wherein the sensor 7, the floor brush structure 2, the first automatic dust suction structure, the second automatic water suction structure and the water delivery structure 8 are all electrically connected to the controller; wherein the sensor 7 is used to detect whether there is water on the ground; and the start state of the first automatic dust suction structure is set to A, and the start state of the second automatic water suction structure is set to B. , the floor brush start state is C, and the water supply structure 8 start state is D; when the sensor 7 detects that there is no water on the ground, the T1 mode is started: the above-mentioned controller controls the A state to be closed after a preset time, and then controls the three states B, C, and D to work for a preset time; when the sensor 7 detects that there is water on the ground, the T2 mode is started: the above-mentioned controller directly controls the three states B, C, and D to work for a preset time; among them, the four states A, B, C, and D are the start states of their respective equipment. For example, when it is in A, the first automatic dust suction structure is started, which can realize the suction of dust in the working chamber 6 into the dust box 4. When B, C, and D are started at the same time, the water supply structure 8 automatically sprays water, and the floor brush structure 2 brushes the ground. At the same time, the second automatic water suction structure sucks the sewage scrubbed on the ground or the sewage on the ground itself into the sewage tank 5.

[0022] The above-mentioned shell 1 includes a mounting seat, a working chamber 6 is arranged in the mounting seat, a support rod 16 is arranged on the upper end of the mounting seat, the support rod 16 is used for manual holding, and is convenient to use. A rolling wheel 15 is arranged at the position where the shell 1 contacts the ground, which is convenient for floor washing operations on uneven surfaces. The floor brush structure 2 includes a roller brush, and the roller brush is provided with a driving motor to realize automatic brushing. The roller brush is provided with the front part of the shell 1, and the front part of the working chamber 6 is opened. The roller brush blocks and seals the front opening. When working, the roller brush rotates counterclockwise to brush the sewage on the ground into the working chamber 6, and then sucks it into the sewage tank 5 through negative pressure.

[0023] If the ground is dry, the dirt is sucked into the dry area dust box 4 in T1 mode, and then the floor washing mode is entered in T2 mode to spray water for cleaning and suck the sewage into the wet area sewage tank 5; if water is detected on the ground, T1 mode is skipped directly to enter T2 mode. It should be noted that in T1 dust suction mode, the floor brush structure 2 does not work, the water delivery structure 8 is closed, and the first automatic dust suction structure is started by controlling the air.

[0024] The sensor 7 detects whether there is water on the ground, and automatically selects to start the T1 mode or the T2 mode to separate the dirt into dry and wet areas. The dry dirt is sucked into the dry area dust box through the vacuum mode, and the sewage is sucked into the sewage tank 5 through the floor washing mode. The dry and wet dirt can be processed separately, solving the problem that the floor washing machine is difficult to clean.

[0025] The first automatic dust suction structure may be connected to the working chamber 6 and the dust box 4 through a negative pressure structure such as an air compressor. When the negative pressure structure is started to generate a negative pressure effect, the dust and other solid impurities in the working chamber 6 can be sucked into the dust box 4. At the same time, a closed structure is provided, which can be automatically opened or closed under the control effect of the controller to achieve the control of the connection state between the working chamber 6 and the dust box 4. Specifically, the first automatic dust suction structure includes a first fan, the working chamber 6 is provided with a first air port, the first air port is provided with a first automatic valve, the first fan suction end is connected to the first air port, and the first fan exhaust end is connected to the dust box 4. When the A state is started, the controller first controls the first automatic valve to open, and then starts the first fan to work, so as to suck the dust in the working chamber 6 into the dust box 4.

[0026] The second automatic water suction structure is similar in structure to the first automatic dust suction structure, and has the same working principle. Specifically, the second automatic water suction structure includes a second fan, the working chamber 6 is provided with a second air outlet, the second air outlet is provided with a second automatic valve, the suction end of the second fan is connected to the second air outlet, and the exhaust end of the second fan is connected to the sewage tank 5. When the B state is started, the controller first controls the second automatic valve to open, and then starts the second fan to suck the sewage in the working chamber 6 into the sewage tank 5.

[0027] In order to ensure reasonable spatial allocation of the second automatic water suction structure and the first automatic dust suction structure in the shell 1, the shell 1 includes a first side and a second side, the first fan, the first air outlet and the dust box 4 are located on the first side of the shell 1, and the second fan, the second air outlet and the sewage tank 5 are located on the second side of the shell 1, to ensure that the overall dust suction system and the water suction system are distributed on both sides of the shell 1, thereby reducing space occupancy and mutual functional interference.

[0028] In another embodiment, the housing 1 is provided with an exhaust device, the first automatic dust suction structure and the second automatic water suction structure respectively include a first channel 9 and a second channel 10, the first channel 9 is provided with a first automatic door 11 and a second automatic door 13 at both ends, the first automatic door 11 is used to connect to the working chamber 6, and the second automatic door 13 is used to connect to the dust box 4; the second channel 10 is provided with a third automatic door 12 and a fourth automatic door 14 at both ends, the third automatic door 12 is used to connect to the working chamber 6, and the fourth automatic door 14 is used to connect to the sewage tank 5, and the exhaust ends of the exhaust device are connected to the first channel 9 and the second channel 10 respectively; the exhaust device, the first automatic door 11, the second automatic door 13, the third automatic door 12 and the fourth automatic door 14 are all electrically connected to the controller. That is to say, in this embodiment, a single exhaust device is used to realize the state of dust suction or water suction in different modes, and the setting of such a single exhaust device can reduce the space occupancy rate, thereby reducing the volume of the entire floor washing device.

[0029] The sensor 7 includes the existing clean water detection sensor 7, and the clean water detection sensor 7 is used in large quantities on floor washing products to detect whether the clean water tank is short of water. The remaining circuits are technologies already available in existing floor washing machines.

[0030] In order to adapt to the floor washing operation in different scenarios, a manual system is also included. When the manual system is enabled, the sensor 7 is in a closed state. The manual system includes a first button and a second button provided on the housing 1. The first button and the second button are both electrically connected to the controller. The first button corresponds to the T1 mode, and the second button corresponds to the T2 mode. After the manual floor washing system is selected, the sensor 7 automatically turns off the sensing state, and starts the T1 mode or the T2 mode by manually judging the environmental state, which can better adapt to the use in different environments.

[0031] Specifically, the water supply structure 8 includes a water pipe, a nozzle is provided at one end of the water pipe facing the ground, and the water pipe is provided with a solenoid valve, which is electrically connected to the controller. When in use, the controller starts to open the solenoid valve, and the tap water in the water pipe is sprayed through the nozzle to the ground corresponding to the opening of the working chamber 6, and then rinsed through the floor brush structure 2. Simultaneously, the sewage after washing is pumped into the sewage tank 5.

[0032] The above-mentioned controller uses an MCU single-chip computer, which automatically controls the opening and closing of various electronic control devices through signal reception and analysis, thereby realizing automatic and precise switching modes of the floor washing machine equipment. It can well solve the problem of separating dry and wet dirt in the floor washing machine, and at the same time solve the pain points of the floor washing machine being difficult to clean, and the problem of hair easily getting entangled in the floor brush. Moreover, this method is simple and convenient, with good cost control.
