When the sweeping robot 100 works, the floor brush 30 installed in the installation cavity 11 can not only brush up dust, paper scraps and other sundries on the ground, but also drive the air in the installation cavity 11 to flow, and the dust, the paper scraps and other sundries brushed up by the floor brush 30 on the ground enter the installation cavity 11 along with the flow of the air; the motor 50 of the sweeping robot 100 drives the air in the mounting cavity 11 to enter the accommodating cavity 12 through the dust suction channel 13, and the cyclone cone 40 in the accommodating cavity 12 separates the air from dust, paper dust and other impurities, so that the air is discharged, and the dust, the paper dust and other impurities are stored in the accommodating cavity 12; the scraping strip 20 is always abutted against the ground in the process that the sweeping robot 100 moves on the ground, so that the dust is prevented from being influenced by air blown out from the cavity opening of the mounting cavity 11, and the problem that the dust flies around is solved; the air flowing in the mounting cavity 11 flows to the side of the scraping strip 20 close to the cavity opening of the mounting cavity 11 through the ventilation structure, so that the dust, paper dust and other sundries accumulated on the side of the scraping strip 20 close to the cavity opening of the mounting cavity 11 are blown up, the dust, paper dust and other sundries accumulated on the side of the scraping strip 20 close to the cavity opening of the mounting cavity 11 are brushed up by the floor brush 30 and brought into the mounting cavity 11, and finally the dust, paper dust and other sundries are sucked into the accommodating cavity for centralized collection and treatment under the action of the fan 40 of the sweeping robot 100.
According to the invention, the strip-shaped mounting cavity 11 is concavely arranged on the lower surface of the shell 10 of the sweeping robot 100, so that the floor brush 30 of the sweeping robot 100 can be mounted; the scraping bar 20 of the sweeping robot 100 extends along the axial direction of the mounting cavity 11 and is mounted on one side of the cavity opening of the mounting cavity 11; the housing 10 of the sweeping robot 100 is further provided with a ventilation structure, which allows the air in the mounting cavity 11 to flow to the side of the scraping bar 20 adjacent to the opening of the mounting cavity 11. So set up for the air of high-speed flow in the installation cavity 11 causes the impact to piling up in the dust, the wastepaper and other debris of the one side of the accent of the neighbouring installation cavity 11 of the bar of scraping 20 behind the ventilation structure, and then makes the dust, the wastepaper and the debris of piling up in the accent one side of the neighbouring installation cavity 11 of the bar of scraping 20 blown up, so just be favorable to piling up in the dust, the wastepaper and other debris of the accent one side of the neighbouring installation cavity 11 of the bar of scraping 20 clean, thereby be favorable to improving the cleaning performance of robot 100 of sweeping the floor.
It is noted that air, dust, paper dust and other impurities entering the accommodating chamber 12 are separated by the cyclone cone 40, and the dust, paper dust and other impurities are collected in the accommodating chamber 12, and the air is exhausted. In order to conveniently remove dust, paper dust and other impurities in the accommodating cavity 12, in an embodiment of the present invention, the housing 10 of the sweeping robot includes a separator 10a and a base plate 10b, the separator 10a is detachably mounted on an upper surface of the base plate 10b, and is provided with the accommodating cavity 12 for mounting the cyclone cone 40, a lower surface portion of the base plate 10b is recessed to form an installation cavity 11 for mounting the floor brush 30, the base plate 10b is further provided with a dust suction channel 13 communicated with the installation cavity 11, and one end of the dust suction channel 13 away from the installation cavity 11 is detachably connected to the separator 10 b. Because the accommodating cavity 12 is arranged on the separator 10a, the separator 10a and the chassis 10b are detachably arranged, so that the separator 10a is conveniently detached from the chassis 10b, and further, the cleaning of dust, paper dust and other impurities in the accommodating cavity 12 is facilitated.
It should be noted that the separator 10a and the chassis 10b can be connected in various ways, such as by a snap connection, a latch connection, etc., which are not necessarily enumerated herein. The connection of the suction channel 13 to the separator 10a is understood to mean a pipe-to-pipe connection, which can be made in various ways, for example, directly by means of a plug-in connection, indirectly by means of an adapter, etc., to name a few.
Since the mounting cavity 11 is disposed on the chassis 10b of the housing 10, and the ventilation structure is correspondingly disposed on the chassis 10b, for convenience of description, the ventilation structure is disposed on the chassis 10b in the following embodiments as an example.
This ventilation structure is mainly to introduce the air that flows at a high speed in the installation cavity 11 to the one side of the accent of scraping strip 20 neighbouring installation cavity 11, that is to say, as long as guarantee this ventilation structure's air intake and installation cavity 11 intercommunication, this ventilation structure's air outlet is located and scrapes the one side setting of the accent of strip 20 neighbouring installation cavity 11, and this ventilation structure's other positions can set up wantonly. In order to simplify the ventilation structure, in an embodiment of the present invention, the ventilation structure extends from the wall of the installation cavity 11 to the lower surface of the base plate 10b between the opening of the installation cavity 11 and the wiper strip 20, that is, the ventilation structure extends substantially along the circumferential direction of the installation cavity 11, so that it is convenient to provide a ventilation channel or a structure similar to the ventilation channel on the base plate 10b or externally provide a tubular structure.
Further, the ventilation structure extends from the wall of the mounting cavity 11 on the side adjacent to the scraping strip 20 to the lower surface of the chassis 10b between the opening of the mounting cavity 11 and the scraping strip 20, so that the overall length of the ventilation structure is shortened to the shortest, and the ventilation structure is convenient to arrange.
Considering that if the ventilation structure is formed by an external tubular structure, the number of components of the sweeping robot 100 is increased, which may further increase the assembly process of the sweeping robot 100, and also decrease the assembly efficiency of the sweeping robot 100. In an embodiment of the present invention, the ventilation structure is formed by a structure on the chassis 10b, and specifically, referring to fig. 3 and fig. 4, a plurality of air guiding grooves 15 extending in the up-down direction are concavely disposed on the cavity wall of the mounting cavity 11 adjacent to the scraping strip 20, and the plurality of air guiding grooves 15 are further arranged at intervals along the axial direction of the mounting cavity 11 to form the ventilation structure.
The upper end and the lower end of the air guide groove 15 are arranged in a penetrating manner, the opening of the mounting cavity 11 is enlarged due to the arrangement of the air guide groove 15, and the air guide groove 15 is arranged at one side close to the scraping strip 20, so that air in the mounting cavity 11 can be blown out along the air guide groove 15 under the driving of the floor brush 30, dust, paper scraps and other impurities accumulated at one side of the scraping strip 20 close to the opening of the mounting cavity 11 are blown up, and the problem that the dust, the paper scraps and other impurities are accumulated at one side of the scraping strip 20 close to the opening of the mounting cavity 11 is solved.
It should be noted that the air guiding groove 15 extending in the up-down direction may be understood as the air guiding groove 15 extending in the up-down direction directly, and may also be understood as the air guiding groove 15 extending in the up-down direction obliquely, and how to arrange the air guiding groove 15 is not limited herein. The plurality of air guide grooves 15 can be formed by a mold during injection molding of the chassis 10b, so that the grooving process is omitted.
It should be noted that the floor brush 30 is generally cylindrical, and the volume of the installation cavity 11 is generally slightly larger than the volume of the floor brush 30, so as to ensure that the floor brush 30 can drive the air in the installation cavity 11 to flow rapidly, that is, the installation cavity 11 is circular along its radial cross section. In view of this, each air guiding groove 15 is arranged tangentially to the mounting cavity 11 adjacent to the cavity wall of the wiper strip 20. With the arrangement, air in the mounting cavity 11 can be directly blown to one side of the scraping strip 20, which is adjacent to the cavity opening of the mounting cavity 11, under the action of centrifugal force and the guiding action of the air guide grooves 15, so that dust, paper scraps and other impurities are prevented from being accumulated at the position.
In addition, each air guiding groove 15 is tangentially arranged on the wall of the mounting cavity 11 adjacent to the scraping strip 20, so that the mold opening of the mold for manufacturing the shell 10 is facilitated, and the production and the manufacture of the chassis 10b are further facilitated.
In order to facilitate the opening of the mold for manufacturing the chassis 10b, other ways may also be used, for example, the very cross section of the air guiding groove 15 is configured to be V-shaped (see fig. 4) or U-shaped (see fig. 5), so that the mounting cavity 11 is disposed in a zigzag shape adjacent to the cavity wall of the wiper strip 20. So set up, on the one hand be convenient for the air along the flow of wind-guiding groove 15, on the other hand is convenient for the die sinking of mould.
In order to facilitate the air flowing along the mounting groove 14, in an embodiment of the present invention, the width of the air guiding groove 15 in the axial direction of the mounting cavity 11 is gradually reduced from top to bottom, so that the width of the cavity wall of the mounting cavity 11 between two adjacent air guiding grooves 15 is gradually increased from top to bottom. That is to say, the cavity wall of the installation cavity 11 between two adjacent air guide grooves 15 is arranged in a triangular shape, so that the resistance of the cavity wall of the installation cavity 11 between two adjacent air guide grooves 15 to the air flow is reduced, and the opening of one end of each air guide groove 15, which is far away from the cavity opening of the installation cavity 11, is relatively large, so that the air can enter the air guide grooves 15 conveniently; and the width of one end, close to the opening of the mounting cavity 11, of each air guide groove 15 is smaller than the width of one end, far away from the opening of the mounting cavity 11, of each air guide groove 15, when air is blown out from one end, close to the opening of the mounting cavity 11, of each air guide groove 15, the speed of the air is increased, so that dust, paper scraps and other impurities accumulated on one side, close to the opening of the mounting cavity 11, of the scraping strip 20 can be blown up better, and further the dust, the paper scraps and other impurities are prevented from being accumulated on one side, close to the opening of the mounting cavity 11, of the scraping strip 20.
It should be reminded that the width of each air guiding groove 15 in the axial direction of the installation cavity 11 is not too large, and if the width is too large, the strength of the side, adjacent to the scraping strip 20, of the cavity opening of the installation cavity 11 is reduced, and further the side, adjacent to the scraping strip 20, of the cavity opening of the installation cavity 11 is easily damaged; the axial width of the mounting cavity 11 of each air guiding groove 15 is not too small, and too small may affect the air flow. In view of this, the width of the air guide groove 15 in the axial direction of the mounting cavity 11 is defined to be 2-5 mm. Therefore, the strength of the side, adjacent to the scraping strip 20, of the cavity opening of the mounting cavity 11 is ensured, and meanwhile, the air can smoothly flow along the air guide groove 15.
The distance between two adjacent air guide grooves 15 is not too large, and if the distance is too large, dust, paper scraps and other impurities at some positions cannot be blown; the distance between two adjacent air guiding grooves 15 is also not suitable to be too small, and too small results in the strength of the side of the opening of the mounting cavity 11 adjacent to the wiper strip 20 being reduced. In view of this, the axial distance between two adjacent air guide grooves 15 in the mounting cavity 11 is 30-60 mm. With this arrangement, it is ensured that the wiper strip 20 can be blown by the flowing air at various positions on the side of the opening of the mounting cavity 11, while also ensuring the strength of the side of the opening of the mounting cavity 11 adjacent to the wiper strip 20.
In another embodiment of the present invention, the ventilation structure is provided by a plurality of air guiding channels provided on the chassis 10b, the plurality of air guiding channels all extend from the cavity wall of the installation cavity 11 to the lower surface of the chassis 10b located at the cavity opening of the installation cavity 11 and directly below the scraping strip 20, and the plurality of air guiding channels are arranged at intervals along the axial direction of the installation cavity 11. With the arrangement, air flowing in the mounting cavity 11 can be guided to one side of the scraping strip 20 close to the cavity opening of the mounting cavity 11, and the problem that dust, paper scraps and other impurities are accumulated on one side of the scraping strip 20 close to the cavity opening of the mounting cavity 11 can be solved.
It should be noted that the main difference between the air guiding channel and the air guiding groove 15 is that only two ends of the air guiding channel are through, two ends of the air guiding groove 15 are through, and one side of the air guiding groove 15 is through, and other configurations of the air guiding channel can refer to the configuration of the air guiding groove 15, and will not be described herein again.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
