Description

Technical Field

[0001] The utility model relates to the technical field of floor cleaning devices, in particular to a floor cleaning robot with high cleaning efficiency. Background Art

[0002] The cleaning ability of a sweeping robot (sweeping machine) is one of the most important performance indicators of the product and one of the most important indicators that affect the user experience. To improve the cleaning ability of sweeping machines, all manufacturers who develop and manufacture sweeping machines have been making unremitting efforts, including improving motor performance, etc. However, improving the power and performance of the motor may be limited by battery technology, usage time, or by factors such as noise reduction, motor technology, and cost. The balance of these limitations has always been a problem that has plagued the improvement of the cleaning ability of existing products. In order to improve the cleaning power, it is usually achieved by increasing the power of the suction motor, because for suction motors of the same efficiency, the higher the power, the greater the suction, and the greater the suction, the better the cleaning ability under the same conditions. However, increasing the power will have the following disadvantages: under the same conditions, higher-power suction motors are more expensive, higher-power suction motors are noisier, resulting in greater noise for the entire machine, and greater power consumption, resulting in a shorter product usage time.

[0003] In addition, the height of the dust inlet of the dust box of the existing sweeping machine from the ground (hereinafter referred to as A dimension) generally needs to be designed to have a certain height, because if the A dimension is reduced, the safe dust holding capacity of the dust box will be reduced by the same amount (that is, if the garbage in the dust box exceeds the safe dust holding capacity, the garbage will leak out). Therefore, in order to ensure the dust box capacity, the A dimension of the existing sweeping machine is generally designed to have a certain height. However, if the A dimension is designed to be too high, it will cause a high retaining wall after the cleaning force and suction force of the roller brush are sucked into the lower inner wall of the air inlet (dust suction port). The higher the retaining wall, the more difficult it will be to suck dust and other garbage into the dust box air inlet, and naturally the cleaning ability of the sweeping machine will be reduced, and the user experience will be poor.

[0026] Refer to Figures 1 - 7, an embodiment of the present utility model provides a floor cleaning robot with high cleaning efficiency, including: a main body 1, a dust storage chamber 101 is arranged inside the main body 1, and a suction motor 2 communicated with the dust storage chamber 101, a rotary brush 3 is arranged on the main body 1, an air inlet 102 is arranged on one side of the dust storage chamber 101 close to the rotary brush 3, the rotary brush 3 is used to sweep dust and other garbage on the ground to the air inlet 102, and the suction motor 2 is used to suck the dust and other garbage at the air inlet 102 into the dust storage chamber 101 for storage. The dust storage chamber 101 includes a bottom wall 1011, and a baffle 4 is convexly arranged between the bottom wall 1011 and the air inlet 102. The baffle 4 in the shape of upward convex makes it difficult for the dust and other garbage on the bottom wall 1011 to leak out of the air inlet 102, and the height of the baffle 4 can be reasonably set according to the capacity of the dust storage chamber 101; a guiding surface 401 is inclinedly arranged on one side of the baffle 4 close to the air inlet 102; for the floor cleaning robot with high cleaning efficiency of the present utility model, a baffle is arranged, so that the dust and other garbage in the dust storage chamber are not easy to leak out from the air inlet; through the arrangement of the baffle, the height of the inner wall at the lower end of the air inlet can be reduced, and at the same time, a guiding surface is arranged on the baffle, which is convenient for the dust and other garbage at the air inlet to enter the air inlet and be guided into the dust storage chamber along the guiding surface for storage, making it easier to suck dust at the air inlet and improving the cleaning efficiency.

[0027] Refer to Figure 1 , Figure 4 and Figure 5 , an included angle B is formed between the guiding surface 401 and the horizontal plane, and the included angle B is 45° - 80°. In this embodiment, the included angle B is 60°, which is convenient for the dust and other garbage to be guided into the dust storage chamber 101 along the guiding surface 401, and improves the problem that the dust and other garbage are not easy to be sucked into the air inlet 102 in the previous structure; in this embodiment, the guiding surface 401 is an inclined plane, and can also be set as a curved surface or other surfaces with a guiding function; a blocking surface 402 is arranged on one side of the baffle 4 away from the air inlet 102, and the blocking surface 402 blocks the dust and other garbage on the bottom wall 1011, so that the garbage is not easy to leak out of the air inlet 102; the blocking surface 402 is a vertical plane, and the blocking effect is good; the air inlet 102 is located obliquely above the rotary brush 3, Figure 5 in which the air inlet 102 is located at the upper right position of the rotary brush 3, and the rotary brush 3 rotates counterclockwise; the air inlet 102 includes an upper end inner wall 1021 and a lower end inner wall 1022, and the rotary brush 3 rotates circumferentially along the direction from the lower end inner wall 1022 to the upper end inner wall 1021, which is convenient for sweeping the dust and other garbage on the ground to the air inlet 102.

[0028] Refer to Figure 1 , Figure 4 and Figure 5, the stopper 4 has an upper end portion 403. The first ground clearance A of the lower inner wall 1022 is less than the second ground clearance C of the upper end portion 403, so that the stopper 4 can prevent dust and other garbage on the bottom wall 1011 from leaking into the air inlet 102. The second ground clearance C is greater than 25 mm. In this embodiment, the second ground clearance C is set to 35 mm, and the blocking effect is good. If the second ground clearance C is set too low, the blocking effect will be affected, making it easy for dust and other garbage to leak out of the air inlet 102. By setting the stopper 4, the setting height of the lower inner wall 1022 of the air inlet (i.e., the first ground clearance A) can be reduced, so that dust and other garbage can enter the air inlet 102 and the dust box 7 more easily, thereby improving the dust suction and cleaning ability. In this embodiment, the first ground clearance A is set to 19.3 mm. A dust blocking piece 8 is hinged at the air inlet 102. The dust blocking piece 8 is hinged at the hinge portion 80. The dust blocking piece 8 rotates and opens toward the side away from the roller brush 3. The main body 1 is provided with a first abutting portion 81 and a second abutting portion 82 for limiting the rotation position of the dust blocking piece 8. When the dust blocking piece 8 rotates and opens in place, the dust blocking piece 8 abuts against the first abutting portion 81. When the dust blocking piece 8 is closed, the dust blocking piece 8 abuts against the second abutting portion 82. The dust blocking piece is made of plastic or other materials and can automatically open (rotational movement) when the suction motor is started, which can be opened by suction or other mechanisms, and can automatically close (fall under the action of gravity or other mechanisms) when the suction motor stops working. The function of the dust blocking piece is to prevent dust leakage when the sweeper is not working or when the dust box is removed. There is a platform 9 between the front of the stopper and the air inlet, and its function is to avoid the opening and closing movement stroke of the dust blocking piece. The length of this section of the platform 9 depends on the design of the structures such as the shape and position of the air inlet and the dust blocking piece. The platform in the drawing example is wider only for illustration and can be appropriately shortened.
