A double suction port design is adopted in which the suction nozzle and the water-absorbing soft glue are used for dust suction and water absorption respectively, and the servo mechanism and the sensing mechanism sense and identify solid garbage, and automatically switch to use the suction nozzle and the water-absorbing soft glue; when the sensing mechanism senses solid garbage, no human intervention is required, and the servo mechanism controls the opening and closing of the two input ends of the three-way pipe to automatically disable the water-absorbing soft glue and enable the suction nozzle to perform strong dust suction cleaning.

[0006] Furthermore, the sensing mechanism includes a plurality of sensors, which are distributed on both sides of the nozzle. The sensors are used to sense solid waste. When the sensors sense the presence of solid waste, they send a signal to the servo mechanism. The sensor senses whether there is solid waste on both sides of the nozzle. When the sensor senses the presence of solid waste, it means that there is solid waste on both sides of the nozzle. A signal is sent to the servo mechanism to make it work and switch to use the nozzle. Otherwise, if the sensor does not sense solid waste, no signal is given to the servo mechanism, and the servo mechanism switches to use the absorbent soft glue.

[0007] Furthermore, the servo mechanism includes a transverse tube, and through holes are constructed on the tube walls at both ends of the transverse tube to connect with the two input ends of the three-way tube, and water suction ports and dust suction ports are respectively constructed on the tube walls at both ends of the transverse tube, and the water suction port and dust suction port correspond to a through hole respectively, the water suction port connects with the second pipeline connected to the water-absorbing soft glue, and the dust suction port connects with the second pipeline connected to the suction nozzle, and plungers are arranged at the tube ports at both ends of the transverse tube, and also includes a driving mechanism, and the driving mechanism is used to drive the plungers at both ends of the transverse tube to block the water suction port / dust suction port.

[0026] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0027] See also Figures 1 to 5The embodiment of the present invention provides a dust suction and water absorption conversion system, including a suction motor, a sewage tank 1 and a first pipeline, wherein the suction motor provides negative pressure, one end of the first pipeline is connected to the sewage tank 1, and the other end of the first pipeline is connected to a three-way pipe 2, wherein the three-way pipe 2 is connected to the first pipeline at the output end, and the three-way pipe 2 has two input ends, and the two input ends of the three-way pipe 2 are respectively connected to a suction nozzle 4 for dust suction and a water-absorbing soft glue 5 for water absorption through a second pipeline 3; the dust suction and water absorption conversion system also includes a servo mechanism and a sensing mechanism, wherein the servo mechanism is used to control the opening and closing of the two input ends of the three-way pipe 2 according to the signal of the sensing mechanism. A double suction port design is adopted in which the suction nozzle 4 and the water-absorbing soft glue 5 are used for dust suction and water absorption respectively, and the servo mechanism and the sensing mechanism sense and identify solid garbage, and automatically switch to use the suction nozzle 4 and the water-absorbing soft glue 5; when the sensing mechanism senses solid garbage, the servo mechanism controls the opening and closing of the two input ends of the three-way pipe 2 without human intervention, so as to automatically disable the water-absorbing soft glue 5 and enable the suction nozzle 4 for strong dust suction and cleaning. The sewage tank 1 is equipped with a filter screen, which can filter the garbage, and the liquid enters the bottom of the garbage tank 3, and the solid garbage is stored on the filter screen. When installed, the suction nozzle 4 is about 4mm above the ground, and the negative pressure provided by the suction motor can suck the solid garbage with an outer diameter of less than 9mm from the suction nozzle 4 into the sewage tank 1.

[0028] The suction motor provides negative pressure; liquid garbage enters the sewage tank 1 through the water-absorbing soft glue 5, the second pipeline 3, the three-way pipe 2 and the first pipeline; solid garbage enters the sewage tank 1 through the suction nozzle 4, the three-way pipe 2 and the first pipeline, and is finally filtered through the filter and stored on the filter.

[0029] The sensing mechanism includes a plurality of sensors 13, which are distributed on both sides of the suction nozzle 4. The sensors 13 are used to sense solid waste. When the sensors 13 sense the presence of solid waste, they send a signal to the servo mechanism. The sensor 13 senses whether there is solid waste on both sides of the suction nozzle 4. When the sensor senses the presence of solid waste, it means that there is solid waste on both sides of the suction nozzle 4, and sends a signal to the servo mechanism to make it work and switch to use the suction nozzle 4. On the contrary, if the sensor 13 does not sense solid waste, no signal is given to the servo mechanism, and the servo mechanism switches to use the absorbent soft glue 5. The sensor 13 can be an infrared sensor 13.

[0030] The servo mechanism includes a transverse tube 6, and through holes are formed on the tube walls at both ends of the transverse tube 6 to connect with the two input ends of the three-way tube 2, and water suction ports 7 and dust suction ports 8 are respectively formed on the tube walls at both ends of the transverse tube 6, and the water suction ports 7 and dust suction ports 8 correspond to one through hole respectively, and the water suction port 7 connects with the second pipeline 3 connected with the water-absorbing soft glue 5, and the dust suction port 8 connects with the second pipeline 3 connected with the suction nozzle 4. Plunger 9 is provided at the two end pipe openings of the transverse tube 6, and a driving mechanism is also included, and the driving mechanism is used to drive the plungers 9 at both ends of the transverse tube 6 to block the water suction port 7 / dust suction port 8. In the specific form of the servo mechanism, the water suction port 7 and dust suction port 8 are set up on the transverse tube 6 to cooperate with the water-absorbing soft glue 5 and the suction nozzle 4, and the plunger 9 is driven by the driving mechanism to block the water suction port 7 / dust suction port 8 to realize the control and use of the water-absorbing soft glue 5 and the suction nozzle 4. When in use, the sensor 13 senses solid waste, the servo mechanism receives the signal, and the servo mechanism drives the plungers 9 at both ends of the transverse tube 6 through the driving mechanism to block the water suction port 7 and open the dust suction port 8; conversely, the sensor 13 does not sense solid waste, the servo mechanism does not receive the signal, and the servo mechanism drives the plungers 9 at both ends of the transverse tube 6 through the driving mechanism to open the water suction port 7 and block the dust suction port 8.

[0031] The plunger 9 blocks the pipe opening at the end of the transverse tube 6, and the plunger 9 can move along the length direction of the transverse tube 6. The plunger 9 moves to a fully inserted state to block the water suction port 7 / dust suction port 8. The driving mechanism includes a push rod 10 and a power source. The push rod 10 is arranged on one side of the transverse tube 6 parallel to the length direction of the transverse tube 6. The two ends of the push rod 10 are respectively fixedly connected to an end of a plunger 9 away from the transverse tube 6. The power source drives the push rod 10 to move parallel to the length direction of the transverse tube 6, so that at least one of the plungers 9 at the two ends of the transverse tube 6 is in a fully inserted state. The push rod 10 is used to drive the plungers 9 at the pipe openings at both ends of the transverse tube 6. When one plunger 9 is in a fully inserted state, one of the water suction port 7 and the dust suction port 8 is blocked, while the water suction port 7 or the dust suction port 8 corresponding to the other plunger 9 is in an open state. The opening and blocking of the water suction port 7 and the dust suction port 8 depends on whether the plunger 9 at the end where the water suction port 7 and the dust suction port 8 are located is in a fully inserted state. If the plunger 9 at the end where the water suction port 7 is located is in a fully inserted state, the water suction port 7 is blocked; if the plunger 9 at the end where the dust suction port 8 is located is in a fully inserted state, the dust suction port 8 is blocked.

[0032] Further, the power source includes a motor 11 and a rack 12, the rack 12 is arranged parallel to the length direction of the transverse tube 6, and the rack 12 is fixedly connected to the push rod 10, and a gear matched with the rack 12 is installed on the rotating shaft of the motor 11, and the rack 12 is meshed with the gear. Specifically, the power source form is provided, and the gear installed on the rotating shaft of the motor 11 cooperates with the rack 12 to realize driving the push rod 10. After the servo mechanism receives the signal of the sensor 13, the electric control board in the servo mechanism issues a command, the motor 11 rotates, drives the rack 12 to move, and thus drives the push rod 10 to move, and realizes the conversion of using the dust suction port 8 on the transverse tube 6; on the contrary, after the servo mechanism does not receive the signal of the sensor 13, the electric control board in the servo mechanism issues a command, the motor 11 rotates in the opposite direction, drives the rack 12 to move, and thus drives the push rod 10 to move, and realizes the conversion of using the water suction port 7 on the transverse tube 6; finally, the conversion of water suction and dust suction functions is realized.

[0033] Furthermore, the water-absorbing soft glue 5 includes two pieces of soft glue arranged in parallel, and a cavity with an open bottom surface is formed between the two pieces of soft glue arranged in parallel, and the cavity is connected to the second pipeline 3. When in use, the two pieces of soft glue are attached to the ground to form the cavity into a closed space, and the negative pressure provided by the suction motor sucks the liquid garbage in the cavity into the sewage tank 1.

[0034] Furthermore, the water-absorbing soft glue 5 is constructed in an arc shape. The arc-shaped water-absorbing soft glue 5 can gather liquid waste when it works close to the ground, which helps to absorb the liquid waste.

[0035] Furthermore, a plurality of notches are provided at the bottom of the soft rubber at the arc-shaped concave side, and the notches are used to guide liquid garbage into the cavity formed between the soft rubbers.

[0036] See also Figures 1 to 5 The embodiment of the present invention provides a floor scrubber equipped with the dust and water absorption conversion system as described above. The floor scrubber is provided with a main disc brush motor to provide torque to rotate the disc brush to rub and decompose garbage.

[0037] The floor scrubber equipped with the dust suction and water suction conversion system can sense and identify solid waste through the servo mechanism and the sensing mechanism, and automatically switch to use the suction nozzle 4 and the water-absorbing soft glue 5; when the sensing mechanism senses solid waste, the servo mechanism controls the opening and closing of the two input ends of the three-way pipe 2 without human intervention, so as to automatically stop using the water-absorbing soft glue 5 and start the suction nozzle 4 for strong dust suction and cleaning. It can effectively improve the cleaning ability and cleaning efficiency, reduce the user's work intensity, and improve the user experience.
