Patent Application
20210145235
The present invention relates to a cleaning robot, and more particularly to a cleaning robot for lifting dust and with multi-directional suction ports that is capable of lifting dust on a travel path of the cleaning robot so as to facilitate dust sucking action.
With the advancement of technology, the application of automation equipment has become more and more extensive. In order to save people the time and physical strength of maintaining a clean environment at home, there are cleaning robots on the market that automatically clean the floor. This kind of cleaning robot can automatically move inside the house, during the moving process, the cleaning brush (including the side brush and the roller brush) at the bottom of the cleaning robot is used to collect dust and garbage, and then the dust and garbage are sucked into the dust collecting box of the cleaning robot to achieve the object of automatically cleaning the floor.
The bristles used in the side brush of this type of cleaning robot are relatively soft materials, and the purpose is to increase the area of contact with the floor through the soft bristles when the side brush rotates and collects dust, so as to achieve the object of effectively collecting dust and garbage. However, for the design of such soft bristles, when the cleaning robot walks on the carpet, because the bristles are too soft and are capable of pushing aside the fluff of the carpet, the cleaning robot can only clean the surface of the carpet, and cannot clean the dust and garbage deposited on the bottom of the fluff, which causes the cleaning robot to be inefficient when cleaning carpets.
As mentioned above, there are still quite a few problems with the current cleaning robots. Therefore, in view of the above problems, the inventor of the present application has made improvement and innovation, and after years of painstaking and devoted research, he finally has succeeded in researching and developing a cleaning robot for lifting dust and with multi-directional suction ports.
In order to solve the above technical problems of the prior art, an object of the present invention to provide a cleaning robot for lifting dust and with multi-directional suction ports capable of effectively cleaning a carpet.
In order to achieve the above object, the cleaning robot for lifting dust and with multi-directional suction ports provided by the present invention mainly comprises a cleaning robot main body, at least one dust lifting device, and at least one dust suction port, wherein the dust lifting device is disposed at a bottom of the cleaning robot main body, and the dust suction port is disposed around the dust lifting device at the bottom of the cleaning robot main body.
Wherein inside the cleaning robot main body is at least disposed with a drive motor and a vacuum cleaner.
Wherein the dust lifting device is a vibration roller or a beater or a structure alike electrically connected to the drive motor.
Wherein the dust lifting device is jet ports connected to the vacuum cleaner by air tubes.
Wherein the air tube is provided with an air valve for controlling air flowing through the air tube, or an outer periphery of the air tube is provided with a clamping device for compressing and releasing the air tube.
The techniques of present invention would be more understandable from the detailed description given herein below and the accompanying figures are provided for better illustration, and thus description and figures are not limitative for present invention, and wherein:
Please refer to
When the embodiment is used, the cleaning robot main body 1 is driven to move by the drive motor 11, and the vibration roller 21 is driven by the drive motor 11 to perform rolling, upward and downward displacement and beating a carpet when the cleaning robot main body 1 is moving in order to push aside fluff of the carpet by rolling action of the vibration roller 21, and to lift up dust deposited on a bottom of the fluff of the carpet by upward and downward displacement and beating actions of the vibration roller 21. Then the two dust suction ports 3 respectively disposed in the moving directions of the vibration roller 11 toward and away from the cleaning robot main body 1 are used to suck the lifted dust into the dust collecting box provided inside the cleaning robot main body 1. Therefore, in this embodiment, the carpet is pushed aside by the vibration roller 21, and the carpet is beaten at the same time, so that the dust at a bottom of the carpet can be effectively lifted. At this time, the dust is sucked into the dust collecting box in the cleaning robot main body 1 by the dust suction ports 3, so that the carpet can be effectively cleaned, thereby preventing the problem of the conventional sweeping robots incapable of performing effective dust vacuuming because of dust deposited on the bottom of the fluff of the carpet.
Please refer to
Wherein the vacuum cleaner 12 is capable of generating a negative pressure, the generated negative pressure is used to suck air and dust from the dust suction port 3 into the dust collecting box inside the cleaning robot main body 1, and simultaneously the inhaled air passes through the air tubes 4 and is ejected from the jet ports 22.
When the embodiment is used, the cleaning robot main body 1 is driven by the drive motor 11 to move, and during traveling of the cleaning robot main body 1, air sucked by the vacuum cleaner 12 passes through the air tubes 4 and is ejected from the jet ports 22. Dust deposited on the bottom of the fluff of the carpet is lifted up, the dust on the carpet is sucked into the dust collecting box through the dust suction port 3 by the vacuum cleaner 12. In addition, by repeating actions of compressing and releasing the air tubes 4 through the clamping devices 5 provided on the outer peripheries of the air tubes 4, ejected air can be intermittently ejected, so that compared with continuous air ejection, the dust deposited on the bottom of the fluff of the carpet can be lifted up more effectively.
As described above, this embodiment can effectively lift the dust deposited on the bottom of the fluff of the carpet through the jet ports 22 by using intermittent jetting method, and suck the dust into the dust collecting box through the dust suction port 3, thereby effectively achieving the object of cleaning the carpet. In addition, since the dust lifted by air jet is scattered around with the airflow, the present embodiment utilizes the annular dust suction port 3 provided around the jet ports 22 to suck the lifted dust into the dust collecting box in all directions without causing the lifted dust to scatter to other places.
In addition, in the cleaning robot for lifting dust and with multi-directional suction ports provided by the present invention, in addition to the structures of the vibration roller 21 and the jet ports 22, the dust lifting device can also be structures such as a beater capable of beating the carpet upwardly and downwardly or pushing aside the fluff of the carpet in order to lift the dust. In addition to the two dust suction ports 3 being respectively disposed at positions in the moving directions of the dust lifting device toward and away from the cleaning robot main body 1, and the annular dust suction port 3 being disposed around the dust lifting device, the dust suction port 3 can also be a plurality of suction ports disposed around the dust lifting device. The structures of the dust lifting device and the dust suction port 3 can be arranged in different combinations (for example, a combination of the vibration roller 21 and the annular dust suction port 3, or a combination of the beater and the plurality of dust suction ports 3 provided around the beater, etc.).
In summary, the cleaning robot for lifting dust and with multi-directional suction ports provided by the present invention lifts the dust deposited on the bottom of the fluff of the carpet through the dust lifting device by vertical pushing, vibration, beating or blowing, and then the lifted dust is sucked into the dust collecting box by the dust suction ports disposed in multi-directions. Therefore, compared with the general cleaning robots that use the soft bristles of a dust collecting brush to horizontally push aside the fluff of the carpet, the cleaning robot for lifting dust and with multi-directional suction ports of the present invention is capable of pushing aside the dense fluff of the carpet and lifting the dust deposited on the bottom of the fluff more effectively, and at the same time, the lifted dust is prevented from scattering around. Therefore, the cleaning robot for lifting dust and with multi-directional suction ports provided by the present invention is capable of cleaning the dust and garbage deposited on the bottom of the fluff of the carpet more effectively.
