FIELD OF THE INVENTION

The present invention relates to the field of dust collectors, in particular to a novel intelligent clean robot.

BACKGROUND OF THE INVENTION

In the traditional clean robot, the friction between a main body and a front bumper in the case of movement is large; the trigger effect at farthermost ends of both sides of the front bumper is poor; and infrared receiving devices disposed on the top of the machine are higher than the main body of the machine, so that the height of the machine is increased, and hence the machine cannot work at some areas with lower height limit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Further description will be given below to the present invention with reference to the accompanying drawings and the preferred embodiments.

Reference numerals in the accompanying drawings: 1. main body; 2. drive wheel; 3. cleaning brush; 4. caster; 5. induction lamp assembly; 6. suction port assembly; 7. storage box assembly; 8. fan assembly; 9. battery pack; 10. front bumper; 11. hanging buckle; 12. detection switch; 13. infrared receiving device.

As illustrated in FIGS. 1 to 7, the present invention provides a novel intelligent clean robot, which comprises a main body 1 and drive wheels 2 configured to drive the main body to move on the ground, cleaning brushes 3 with cleaning function, a caster 4 with guide function, induction lamp assemblies 5 with the functions of preventing falls and receiving signals, a suction port assembly 6 disposed on the lower part of the main body and used for vacuum cleaning, a storage box assembly 7 configured to store garbage and dust, a fan assembly 8 with the air exhaust function, and a battery pack 9 configured to supply energy for the machine, disposed in the main body. The novel intelligent clean robot provided by the present invention further comprises a front bumper 10 disposed on the outside of the main body 1. The front bumper 10 is provided with hanging buckles 11 and movably connected to the main body through the hanging buckles 11. Detection switches 12 are disposed on the outside of the front bumper 10. Infrared receiving devices 13 are disposed on the side of the main body 1. The front bumper 10 is configured to change direction when sensing front obstacles or colliding objects.

As illustrated in FIGS. 6 and 7, the hanging buckles 11 are disposed on the machine (in the example, four hanging buckles 11 made from polyformaldehyde (POM) materials are symmetrically disposed on the inner upper side of the front bumper); and the front bumper 10 is movably connected to the main body through the hanging buckles 11 so that the front bumper 10 cannot be disengaged from the main body. When colliding with an obstacle, the front bumper 10 can move within the range defined by the hanging buckles 11 and trigger and collide with the detection switch, so that the friction between the main body and the front bumper 10 can be reduced.

As illustrated in FIG. 5, the detection switches 12 are numerous (four in the embodiment). In the example, the detection switches 12 are symmetrically disposed on both sides of the front bumper 10 to ensure that every position in collision with the front bumper 10 can be sensitively triggered. When the front bumper 10 collides with an obstacle, the collision position moves back and the detection switch at the collision position is triggered to drive the wheelset to change direction and keep away from the obstacle.

As illustrated in FIG. 4, the infrared receiving devices 13 are numerous (three in the embodiment). In the example, one is disposed at a position close to a nameplate and the other two are symmetrically disposed at positions close to the cleaning brushes. When the front bumper 10 collides with an obstacle, the collision position moves back and the detection switch 12 at the collision position is triggered to drive the wheelset to change direction and keep away from the obstacle. The function of the infrared receiving devices on the top is replaced and the height of the entire machine is reduced so that the machine can work at cleaning areas with lower height limit.

The working principle of the machine is as follows:

1. When a power switch is pressed, the battery of the machine is switched on. Under the control of an electronic control part, a fan, the cleaning brushes, a floor brush and the wheelset start to run. Meanwhile, sensors (for collision sensing and ground clearance induction) start to work, and the electronic control part controls the machine to make corresponding actions according to sensor signals.

2. When the built-in infrared detection switches on the front bumper sense the front obstacle, the wheelset and the caster change the movement direction.

3. When the induction lamps detect that the front is high up, the direction will be changed to prevent falls.

4. In the vacuum suction mode: when the machine starts to work, a side brush motor and a fan motor are energized; the side brush motor drives a left side brush and a right side brush to rotate to clean garbage in the vicinity of the machine to the vicinity of a suction port; under the drive of the fan motor, the fan rotates at high speed, so that complete high-speed air flow is produced in an air duct formed by a nozzle, a dust chamber, a coarse filter screen, a coarse filter screen holder, a dust chamber upper cover, a fine filter screen, a fine filter screen holder, an upper cover, a motor upper cover, a motor lower cover, a lower cover and a battery cover; the high-speed air flow results in specific pressure difference between the atmospheric pressure in the ventilation system and the ambient atmospheric pressure, so that specific suction is produced at the suction port; in the travelling process of the machine, the floor brush mounted at the bottom of the lower cover is configured to clean the floor and collect the garbage on the ground to an air inlet of the nozzle; with the accumulation of the garbage, the cross section of the air duct between the air inlet of the nozzle and the external environment is smaller and smaller, and the suction at the air inlet of the nozzle is gradually increased; and the collected garbage is sucked into the entire ventilation system and eventually stored in the dust storage box.

5. When the dust runs through the nozzle and enters an inner space of the dust storage box, the dust is blocked by the coarse filter screen; large dust particles are blocked to the inside of the dust storage box, and relatively small garbage continuously moves ahead along the air dust; when running through the fine filter screen, relatively small garbage particles are blocked by the fine filter screen and also blocked to the inside of the dust storage box; and the remaining extremely small particles continuously move ahead along the ventilation system and are discharged into specific areas on the outside of the machine through specific holes on the upper cover under the high-speed drive of fan blades. The air flow is recycled through an exposed motor housing during the high-speed movement, and the heating motor is sufficiently cooled.

The foregoing is further detailed description given to the present invention with reference to the preferred embodiments and not intended to limit the preferred embodiments of the present invention. A plurality of simple deductions or replacements may also be made by those skilled in the art without departing from the concept of the present invention and should all fall within the scope of protection of the present invention.
