Hereinafter, the cleaning robot is explained as an example of an intelligent cleaning robot.
As shown in fig. 1, the embodiment of the present invention provides a cleaning robot, including: body 10, fan subassembly 20, wind channel extension assembly 30 and dirt box 40, fan subassembly 20 and wind channel extension assembly 30 are fixed to be located inside body 10.
As shown in fig. 1-4, the body 10 includes an air inlet slot 101 disposed at the bottom, and an air outlet slot 102 disposed at the side of the body 10; the blower assembly 20 includes a housing, an air inlet channel 201, an air outlet channel 202 formed inside the housing, and a fan and a driving motor (not shown in the figure) configured to drive an air flow to enter from the air inlet channel 201 and to be discharged from the air outlet channel 202 when rotating, the fan and the driving motor being disposed inside the housing; the air duct extension assembly 30 comprises an air inlet end 301 and an air outlet end 302; an air inlet 401, a dust collection cavity 402, a filter element 403 and an air outlet 404 are sequentially arranged in the dust box 40. The fan assembly 20 is fixed inside the body 10, the dust box 40 is detachably arranged at the tail part of the body 10, and two ends of the air duct extension assembly 30 are respectively connected to the fan assembly 20 and the air outlet groove 102. Wherein, the air inlet 401 of the dust box 40 is butted with the air inlet groove 101, the air outlet 404 is butted with the air inlet channel 201, the air current in the dust box 40 sequentially flows through the air inlet 401, the dust collecting cavity 402, the filter element 403 and the air outlet 404, the dust such as convoluted dust on the ground is blocked by the filter element 403 and collected in the dust collecting cavity 402, and the filtered air current is discharged out of the dust box 40 from the air outlet 404; the air inlet channel 201 of the fan assembly 20 is butted with the air outlet 404 of the dust box 40, so that an air flow path with power is constructed through the suction force of the fan; the air outlet channel 202 of the fan assembly 20 is connected to the air inlet end 301 of the air duct extension assembly 30, the air ducts form a complete air path loop, the butt joint or connection of the components adopts a full-sealing structure, so as to ensure the air tightness of the air duct, and a specific implementation manner, such as sealing is realized by glue adhesion.
In the scheme of this embodiment, air-out groove 102 is the partial casing of the body 10 of fretwork, and air-out end 302 and this body coupling of wind channel extension subassembly 30, and the exhalant gas passes through the air-out groove 102 of fretwork and discharges outside the body 10, can not influence the pleasing to the eye realization of appearance and the function of cleaning machines people like this. The air outlet slot 102 is located at a position relatively behind the forward direction of the body 10, preferably at the side of the rear half of the body 10, so that the exhausted air flow with impurities can flow in a direction away from the body 10, and the pollution of the appearance of the machine caused by the exhausted air adhered to the machine body is reduced. In order to obtain a more optimized effect, the air duct extension assembly 30 further includes a sealing soft rubber member 303 located at a connection position of the air duct extension assembly 30 and the air outlet slot 102, preferably in an annular shape, which can buffer vibration generated in a working process of the fan assembly and prevent impact on the appearance of the machine body. In addition, if the air outlet groove 102 is directly fixed to the edge of the main body 10, the function of exhausting air to the outside of the main body 10 can be realized.
In practical application, the air duct extension assembly 30 is disposed in a physical gap inside the body, such as a gap between the driving wheel and the electric control board, so that the empty space inside can be utilized to a great extent, and the size of the cleaning robot is reduced. As shown in fig. 3, in the cleaning process of the cleaning robot, the airflow sequentially passes through the air inlet duct 101 → the air inlet 401 → the dust collection chamber 402 → the filter element 403 → the air outlet 404 → the air inlet channel 201 → the air outlet channel 202 → the air inlet end 301 → the air outlet end 302 → the air outlet duct 102 according to the arrow shown in the figure, so as to form a complete airflow duct for exhausting the airflow out of the body, and the filter element 403 and the dust collection chamber 402 cooperate to accommodate the ground dust, so that the airflow entering the fan assembly 20 is cleaner airflow, and because the fully sealed complete airflow duct prevents a small part of fine particle dust mixed and permeated in the airflow from being directly discharged inside the body 10, the malfunction of the cleaning robot caused by the dust accumulation is reduced.
In addition, in this embodiment, in order to make the fan assembly 20 achieve a better power function, the air inlet channel 201 is in a bell mouth shape, and the windward wall of the air inlet channel is in an arc shape, so that the resistance to the flow of the air flow is smaller while the air flow is ensured to provide a larger suction force to the greatest extent, so as to improve the overall dust collection power and performance. The air duct extension assembly 30 is fixed inside the body in a bending mode, so that the internal vacant physical space can be utilized to the maximum degree, and the air duct can be extended as far as possible to reduce or eliminate the generated noise.
In another preferred embodiment, the cross-sectional area of the air duct extension assembly 30 increases with the distance from the air outlet channel 202 of the fan assembly 20, that is, the cross-sectional area of the air duct closer to the body 10 is larger, so that the flow rate is larger when the air duct is closer to the outside of the body, which may be beneficial to reducing the noise transmitted to the outside.
In another preferred embodiment, the air duct extension assembly 30 further includes a fixing member 304 for fixing to the body 10, the fixing member 304 is disposed on an outer surface of the air duct extension assembly 30 to be used for fixing to the body 10, the fixing member 304 is a buckle clamped inside the body 10, and the buckle can be mechanically fixed by opening and closing the buckle.
The dust box 40 at the rear of the main body 10 of the present embodiment may be changed to a dust collecting device at the middle of the machine, and the sequence of the air path formed by the dust box is not changed by the position change. The difference between the drawings of the present embodiment is that the internal structure is slightly changed, for example, the air duct extension assembly 30 is changed to be fixed at the rear position of the cleaning robot body 10, the placing position is changed, and the like.
The embodiments disclosed are merely exemplary embodiments for the purpose of illustrating the invention, and should not be considered as limiting the scope of the invention, and certainly not limiting the scope of the invention, for those skilled in the art, it will be understood that various equivalent changes, modifications, variations, etc. may be made in the claims, and all such modifications and equivalents may be included within the scope of the invention.
