Referring to fig. 1 to 5, a sweeper includes: the chassis 1 is arranged at the bottom of the sweeper; a dust box 6 arranged on the chassis 1; the air suction piece 2 is arranged on the chassis 1 in a penetrating way and is provided with an air inlet 21 and an air outlet 22, and the air suction piece 2 enables the dust box 6 to be communicated with the outside; a pressing block 3 arranged below the chassis 1; the driving device is arranged in the machine body of the sweeper and is used for driving the pressing block 3 to press down; the driving device drives the pressing block 3 to press down, so that the distance between the pressing block 3 and the ground is shortened, and the suction negative pressure of the air inlet 21 is increased. In the prior art, if the suction force is increased to solve the problem of insufficient suction force when cleaning the blanket by increasing the power of the blower, the sweeper needs to be provided with a blower with higher power, so that the volume of the sweeper needs to be correspondingly increased and the production cost is increased. If the air inlet 21 of the air suction member 2 is closely attached to the blanket by lowering the height of the chassis 1 to solve the problem of insufficient suction force when cleaning the blanket, the floor sweeping machine will be affected to cross the threshold and block the garbage. Thus, the above-described technical problems can be solved by driving the ascent and descent of the pressing block 3 by the driving means. When the blanket is cleaned by the sweeper, the driving device drives the pressing block 3 to press downwards, the distance between the pressing block 3 and the blanket is controlled, and the suction negative pressure of the air inlet 21 is increased. The principle is as follows: when the air volume passing through the air inlet 21 is a certain amount, the distance between the pressing block 3 and the blanket is shortened, which is equivalent to compressing the air inlet space near the air inlet 21, so that the air inlet speed is increased when the air inlet space is compressed. Under the condition that the wind speed is increased, the negative pressure is increased, and the suction force on the garbage in the blanket is increased, so that the dust collection efficiency is improved. When the sweeper needs to pass the threshold or touch the rubbish of comparatively big piece, drive arrangement drives briquetting 3 and rises, makes the distance of briquetting 3 and ground resume normal, when not working on the woollen blanket like this, also can normally work, avoids influencing the threshold and blockking rubbish, has improved the suitability and the application scene of sweeper greatly. In summary, as long as the air intake space near the air intake 21 is compressed, the air intake speed will be increased, so that the negative pressure can be increased, and the dust collection efficiency is improved. Therefore, the position of the briquette 3 need not be specifically limited. In a preferred embodiment, the pressure piece 3 is located in front of the air inlet 21. The sweeper moves along the direction in front of the air inlet 21 in most cases, so that the air suction member 2 can absorb the garbage in front of the air inlet 21 orderly. The briquetting 3 is located the place ahead of air intake 21 can effectively increase the negative pressure in air intake 21 place ahead, and when the sweeper moved forward, rubbish can effectively be sucked into in the dirt box 6. Compared with the pressing block 3 arranged at other positions, the pressing block 3 is arranged in front of the air inlet 21, and the dust collection efficiency is higher.
In a possible implementation manner, the air suction piece 2 is connected with the pressing block 3, the air suction piece 2 is of a telescopic structure, the driving device drives the pressing block 3 to press down, and the pressing block 3 drives the air suction piece 2 to stretch. Further, the distance between the pressing block 3 and the air suction piece 2 and the ground is shortened, so that the suction negative pressure of the air inlet 21 is further increased. In this embodiment, the suction port of the suction member 2 and the suction port of the pressing block 3 are installed as an integral structure or form a clamping structure by the cooperation of the protrusion and the groove 30. Because the air suction piece 2 is connected with the pressing block 3 and the air suction piece 2 is of a telescopic structure, when the pressing block 3 is pressed down, the air suction piece 2 is lengthened, the air inlet 21 is closer to the ground, and the air suction piece is matched with the pressing block 3, so that the dust collection effect is better. The telescopic structure in this example embodiment may take many forms. For example, the air suction member 2 is composed of an upper air pipe and a lower air pipe. The upper section of the upper section air pipe is fixed, the lower end of the upper section air pipe and the upper end of the lower section air pipe are sleeved with each other, and the lower section air pipe can perform linear telescopic displacement relative to the upper section air pipe. The pressing block 3 is connected with the lower end of the lower-section air pipe, and when the pressing block 3 is pressed downwards, the lower-section air pipe is driven to move downwards relative to the upper air pipe, so that the length of the whole air suction piece 2 is prolonged, and meanwhile, the air suction inlet is more close to a blanket. Considering that in this embodiment, the air suction member 2 is obliquely arranged, and the upper-section air pipe and the lower-section air pipe can be made of materials with smooth surfaces, so that the friction force of the upper-section air pipe and the lower-section air pipe in relative displacement is reduced, the resistance of the lower-section air pipe in displacement obliquely downwards is reduced, and the whole operation process is smoother. The suction member 2 of the present invention is only to name a few more possible ways of achieving the same telescopic function and is also included within the scope of the present invention as defined in the claims.
In a more preferable scheme, the air suction member 2 is a telescopic corrugated pipe, an air inlet 21 of the corrugated pipe is connected with the pressing block 3, a limiting protrusion 23 is arranged at an air outlet 22 of the corrugated pipe, the limiting protrusion 23 is connected in the dust box 6, the air inlet 21 of the corrugated pipe is close to the ground under the driving of the pressing block 3, and an air outlet 22 of the corrugated pipe is fixed under the action of the limiting protrusion 23. The telescopic bellows is adopted as the suction member 2 because the bellows has elasticity and can generate displacement under the action of pressure, axial force, transverse force or bending moment. Therefore, compared with the two-section type air duct structure, the corrugated pipe has stronger adaptability and applicability. The corrugated pipe in the embodiment is sleeved in an inclined channel formed on the upper surface of the chassis 1, the peripheral side wall in the channel limits the movement of the corrugated pipe only towards the side wall direction, and after the upper end is positioned under the fixing effect of the limiting convex block, the pressing block 3 moves downwards to drive the corrugated pipe to stretch, and the running direction of the corrugated pipe is parallel to the peripheral side wall due to the existence of the peripheral side wall. The corrugated pipe with the air inlet 21 is straightened, so that the air inlet 21 is closer to the ground, and the dust collection effect is better.
The structure of the driving means may take many forms. For example, a link mechanism is arranged at the driving end of the motor, the link mechanism is connected with the pressing block 3, the motor drives the pressing block 3 to move up and down by utilizing the link mechanism, for example, a cam is arranged at the driving end of the motor, the cam is abutted with the pressing block 3, the pressing block 3 is connected with the spring 35, and the up and down movement of the pressing block 3 is controlled under the cooperation of the cam and the spring 35. Referring to fig. 3 and 4, in a preferred embodiment, the driving device includes a driving motor 31 disposed in the machine body of the sweeper, a gear 32 disposed at an output end of the driving motor 31, and a rack 33 meshed with the gear 32, wherein a bottom end of the rack 33 is connected with the pressing block 3, and the driving motor 31 drives the gear 32 to rotate, so as to drive the rack 33 to press the pressing block 3. Because the air inlet 21 in this scheme is a bar hole that both ends extend from chassis 1 middle part to chassis 1 both sides, the length and the width of briquetting 3 also lengthen and widen correspondingly, form a great rectangle briquetting 3 of area. The area of the pressing block 3 is increased, so that the space around the air inlet 21 is compressed, and the negative pressure suction force is improved. Therefore, the gear 32 in the scheme is a cross gear 32 with a strip structure, that is, the axial length of the gear 32 is greater than the radial length of the gear 32. Correspondingly, the rack 33 is also of plate-like construction, with three ribs for improved support being formed on the back. The cross gear 32 of the strip structure and the rack 33 of the plate structure improve the stability of the pressing block 3 in the ascending or descending process, so that the heights of all positions of the pressing block 3 are kept consistent.
In a possible embodiment, the lower surface of the chassis 1 is concavely formed with a receiving groove 11 adapted to the pressing block 3, and the pressing block 3 is received in the receiving groove 11 when the driving device drives the pressing block 3 to rise. The arrangement of the receiving groove 11 provides sufficient space for the briquette 3 to be lifted and pushed down without changing the height of the chassis 1. In addition, since the accommodating groove 11 is matched with the pressing block 3, the accommodating groove 11 also plays a limiting role in the process of ascending and descending the pressing block 3, and the shifting in the shifting process is prevented.
Further, a scraping plate 5 is arranged on the lower surface of the chassis 1, the scraping plate 5 is located on one side, opposite to the pressing block 3, of the air inlet 21, a pressing plate 4 is arranged on the upper side of the scraping plate 5, and the pressing plate 4 is fixedly connected with the chassis 1 through screws. Referring to the figure, the inner side of the middle part of the scraping plate 5 is flush with the inner side of the air inlet 21, the head end and the tail end of the scraping plate 5 extend obliquely outwards, and the scraping plate 5 is made of soft materials, so that when the sweeper cleans, the scraping plate 5 can adapt to a plurality of working conditions, and the height of the scraping plate 5 can be larger than the distance from the bottom shell of the cleaner to the ground, so that the cleaning of the ground is ensured to be cleaner. Since the pressing block 3 is disposed in front of the air inlet 21, the pressing block 3 can compress only the space in front of the air inlet 21. However, the space behind the air inlet 21 remains at the same height as the chassis 1 and the bottom surface due to the absence of the pressure block 3. The space behind the air inlet 21 can be compressed by the arrangement of the scraping plate 5, the scraping plate is matched with the pressing block 3, the space near the air inlet 21 is further compressed, and the suction force can be further improved. When the sweeper moves, the scraping plate 5 contacts with the ground and is matched with the pressing block 3 in front of the air inlet 21, so that garbage enters the sweeper from the air suction piece 2 under the combined action of the scraping plate 5 and the pressing block 3.
Further, an agitating mechanism is arranged on the pressing block 3. Because the blanket stores ash deeply and is generally stepped on by a human body, the blanket is difficult to directly adsorb by a sweeper, and the ash in deep level is stirred by high-speed stirring of a stirring mechanism. Under the stirring action of the stirring mechanism, the deep ash is stirred to fly up, so that the deep ash is easily absorbed into the machine body by the sweeper, which is equivalent to deep cleaning, and the cleaning efficiency is greatly improved.
The structure of the stirring mechanism has various forms. For example, the agitation mechanism includes a drive motor and an agitator disk. The driving motor is arranged in the machine body of the sweeper, and the axis of the driving end of the driving motor is parallel to the ground. A part of the stirring disk is exposed out of the chassis of the sweeper and is connected with the output of the driving motor. When the driving motor rotates, the stirring disc is tangent to the ground, so that dust in the blanket is stirred. Referring to fig. 5, in one possible embodiment, the stirring mechanism includes a driving motor 37 provided on the lower surface of the pressing block 3, an electromagnetic block 36 embedded on the pressing block 3, a spring 35 provided on the upper surface of the pressing block 3 and corresponding to the position of the electromagnetic block 36, a ferromagnetic cover plate 34 provided on the upper end portion of the spring 35, and a rotating shaft 38 with a stirring disk 39 connected to the lower end portion thereof, wherein the rotating shaft 38 sequentially passes through the driving motor 37, the electromagnetic block 36, and the spring 35 from bottom to top until the upper end portion of the rotating shaft 38 is connected to the ferromagnetic cover plate 34; the electromagnetic block 36 has strong magnetism when energized and attracts the strong magnetic cover 34, so that the rotating shaft 38 drives the stirring disk 39 to press down.
