Description

Technical Field

[0001] The utility model relates to the technical field of dust cleaning, in particular to a dust cleaning device. Background Art

[0002] There will inevitably be a lot of dust in the production environment of sand materials, and the workshop needs to be cleaned frequently. However, since most of the cleaning targets are dust, the conventional manual cleaning method will cause dust to fly, and the dust will settle again after cleaning, resulting in poor cleaning effect. Secondly, the cleaning staff will be in this link for a long time, which is not good for their health.

[0003] Therefore, negative pressure vacuum cleaners are often used to clean the dust. However, it is often difficult for vacuum cleaners to suck up some residual dust or dust in corners. Therefore, blowers are often used to blow up the dust before sucking it up. However, the blown dust is easy to fly around before being sucked away. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model proposes a dust cleaning device to solve the technical problem mentioned in the background technology that dust is often blown up to facilitate dust cleaning, resulting in dust flying everywhere.

[0010] Furthermore, the driving mechanism includes a motor, a driving component, a driven component and a pressing component; the motor is arranged on the shell, the driving component is rotatably connected to the motor, the driven component is rotatably connected to the shell, and the driving component can intermittently drive the driven component to rotate; the pressing component is elastic and slidably connected to the shell, and the rotation of the driven component can drive the pressing component to squeeze the touch switch of the blower.

[0011] Furthermore, the driving assembly includes a driving shaft, a turntable, a toggle rod and an arc block; the driving shaft is coaxially fixed on the output shaft of the motor, the turntable is coaxially fixed on the driving shaft, the toggle rod is eccentrically erected on the turntable, and can intermittently drive the driven assembly to rotate; the arc block is coaxially arranged on the turntable, and can limit its position in the rotation gap of the driven assembly.

Since the blowing is intermittent, it can blow up the dust that is difficult to suck away for easy suction, while reducing the dust flying around. At the same time, since the blowing occurs in the suction hood, it can reduce the dust from escaping the suction hood. That is to say, by intermittently spraying air and the suction hood, it is easy to clean and reduce the escape of dust. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0023] Please also read Figure 1 and Figure 2 , this embodiment provides a dust cleaning device, including a housing 1, a negative pressure exhaust fan 2, a dust collecting mechanism 3, an air suction pipe 4, an air suction hood 5, an air jet mechanism 6 and a driving mechanism 7;

[0024] The negative pressure exhaust fan 2 is arranged in the housing 1, one end of the negative pressure exhaust fan 2 is connected to the dust collecting mechanism 3, and the other end is connected to the suction hood 5 through the suction pipe 4; specifically, the dust collecting mechanism 3 is similar to the dust collecting mechanism 3 in a common vacuum cleaner, the dust bag or dust box is connected to the negative pressure exhaust fan 2 through a pipeline, and the negative pressure exhaust fan 2 discharges the extracted dust into the dust bag or dust box, and the dust bag or dust box is provided with air holes and filters, and the dust is retained in the dust bag or dust box on the basis of air permeability. Preferably, the housing 1 is provided with air holes accordingly. It should also be understood that the switch of the negative pressure exhaust fan 2 is arranged on the housing 1 or the housing 1 is provided with a through hole that can be pressed to the switch, or it can be turned on and off by a remote control or other mechanism.

[0025] The jet mechanism 6 includes a blower 61, a jet pipe 62 and a jet head 63; the blower 61 is arranged on the housing 1 and is connected to the jet head 63 through the jet pipe 62; the jet head 63 is arranged on the suction hood 5 and can spray into the suction hood 5; specifically, a plurality of jet heads 63 can be provided, and a plurality of jet heads 63 can spray at the same time through the jet pipe 62. It should be understood that when in use, the suction hood 5 should be as close to or as close to the ground as possible so that the dust blown up by the air is as much as possible in the suction hood 5.

[0026] The blower 61 is controlled by a touch switch 611 . The driving mechanism 7 is disposed on the housing 1 and can intermittently squeeze the touch switch 611 of the blower 61 .

[0027] After starting the negative pressure exhaust fan 2, by starting the driving mechanism 7, the driving mechanism 7 intermittently squeezes the touch switch 611 of the blower 61, and then intermittently sprays air into the suction hood 5, so as to blow up the corners or stubborn dust surrounded by the suction hood 5, so that the negative pressure exhaust fan 2 can easily suck away the dust. Since the blowing is intermittent, the dust that is not easy to be sucked away can be blown up for easy suction, while reducing the dust flying around. At the same time, since the blowing occurs in the suction hood 5, the dust can be reduced from escaping the suction hood 5. That is to say, by intermittently spraying air and the suction hood 5, it is easy to clean and reduce the escape of dust.

[0028] In other schemes, the driving mechanism 7 includes a motor 71, a driving assembly 72, a driven assembly 73 and a pressing assembly 74; the motor 71 is arranged on the housing 1, the driving assembly 72 is rotatably connected to the motor 71, the driven assembly 73 is rotatably connected to the housing 1, and the driving assembly 72 can intermittently drive the driven assembly 73 to rotate; the pressing assembly 74 is elastic and slidably connected to the housing 1, and the rotation of the driven assembly 73 can drive the pressing assembly 74 to squeeze the touch switch 611 of the blower 61. It should be understood that the driven assembly 73 intermittently rotates, that is, intermittently approaches and moves away from the pressing assembly 74, and the driven assembly 73 approaches and pushes the pressing assembly 74 to squeeze the touch switch 611 of the blower 61. After the driven assembly 73 moves away, the pressing assembly 74 is reset by its own elasticity and moves away from the touch switch 611 of the blower 61, and the blower 61 stops blowing.

[0029] In other embodiments, the driving assembly 72 includes a driving shaft 721, a rotating disk 722, a toggle rod 723 and an arc block 724; the driving shaft 721 is coaxially fixed on the output shaft of the motor 71, the rotating disk 722 is coaxially fixed on the driving shaft 721, the toggle rod 723 is eccentrically erected on the rotating disk 722, and can intermittently drive the driven assembly 73 to rotate; the arc block 724 is coaxially arranged on the rotating disk 722, and can limit its position in the rotation gap of the driven assembly 73. That is, the arc block 724 abuts against the driven assembly 73 in the rotation gap of the driven assembly 73, thereby limiting the rotation of the driven assembly 73 due to external force.

[0030] In other schemes, the driven assembly 73 includes a driven shaft 731, a groove wheel 732 and an incomplete gear 733; the driven shaft 731 is rotatably connected to the housing 1, the groove wheel 732 and the incomplete gear 733 are coaxially fixed on the driven shaft 731, the toggle lever 723 can intermittently drive the groove wheel 732 to rotate, the arc block 724 can limit the position of the groove wheel 732 in the rotation gap of the groove wheel 732, and the incomplete gear 733 can intermittently drive the pressing assembly 74 to slide. Specifically, after the incomplete gear 733 drives the pressing assembly 74 to squeeze the touch switch 611 of the blower 61, the arc block 724 limits the rotation of the groove wheel 732, thereby limiting the reset of the pressing assembly 74 due to its own elastic force, so that the blowing can be maintained for a short period of time, and as the gear teeth of the incomplete gear 733 leave the pressing assembly 74, the pressing assembly 74 is reset by its own elastic force and moves away from the blower 61.

[0031] In other embodiments, the pressing assembly 74 includes a rack 741, a pressing plate 742, a spring 743 and a fixing plate 744; the rack 741 is slidably connected to the housing 1 and can mesh with the incomplete gear 733; the pressing plate 742 is disposed at one end of the rack 741 close to the blower 61, the pressing plate 742 is connected to the fixing plate 744 through the spring 743, and the fixing plate 744 is fixed to the housing 1. It should be understood that the rack 741 can perform linear reciprocating sliding in the direction of the touch switch 611 of the blower 61, and press the touch switch 611 of the blower 61 through the pressing plate 742.

[0032] In other schemes, a flexible plate 8 is provided around the bottom of the air hood 5. By providing the flexible plate 8, the air hood 5 can be more closely attached to the ground, and the gap between the air hood 5 and the ground can be further reduced to avoid dust flying when blowing.

[0033] It should also be understood that, during operation, the motor 71 and the negative pressure exhaust fan 2 should both be turned on. The dust cleaning device described above facilitates cleaning while reducing dust escape by intermittently spraying and sucking air.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
