Description

Technical Field

[0001] This utility model belongs to the field of dust cleaning technology, specifically a dust cleaning device. Background Technology

[0002] Dust cleaning devices, also known as vacuum cleaners, are used to clean up large amounts of fine particles (such as cement dust, wood chips, and metal shavings) generated during construction. Traditional brooms are difficult to clean them thoroughly, so handheld vacuum cleaners are usually used to collect them quickly with strong suction, avoiding dust and secondary pollution.

[0003] Utility model patent application publication number 202222179004.3 discloses a dust cleaning device, belonging to the field of dust treatment technology. This utility model includes a dust cover, a flexible hose, a rigid hose, a mounting housing, a centrifugal fan, a motor, an air outlet pipe, an air outlet, a filter, and a dust collection box. The rigid hose is connected to the dust cover, and a flexible hose is installed at one end of the rigid hose. A centrifugal fan is installed, and the suction port of the centrifugal fan is connected to the rigid hose. The rigid hose is connected to the dust cover. When the dust cover is placed on an irregular surface and the device is started, the motor drives the impeller inside the centrifugal fan to rotate, causing the dust on the irregular surface to be lifted and, under rapid suction, drawn into the rigid hose along with the surrounding air. Finally, the air is discharged from the air outlet, and the dust falls into the dust collection box, thus effectively cleaning the dust on irregular surfaces, preventing dust residue on irregular surfaces, and reducing the health and safety hazards caused by dust.

[0004] As can be seen from the aforementioned patent, there is a dust cleaning device, but it still has shortcomings in actual use. The most obvious one is that when performing dust cleaning operations, a filter screen is usually used to intercept dust and other impurities and keep them in the collection cylinder. However, as the filter screen is used for a long time, some dust and other impurities will gradually adhere to the surface of the filter screen, thereby hindering the normal air intake of the dust extraction fan and reducing the dust removal effect of the dust cleaning device. Therefore, we propose a dust cleaning device. Utility Model Content

[0005] The purpose of this invention is to provide a dust cleaning device to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] Specifically, this application describes a dust cleaning device, comprising: a suction pipe and a suction fan disposed at one end of the suction pipe, wherein a collection cylinder is threadedly connected to one end of the suction pipe, and multiple sets of rubber sheets are fixedly connected to the lower end of the inner cavity of the collection cylinder.

[0008] The inner sidewall of the collection cylinder has through holes at both ends. A dust collection cylinder is threaded to the sidewall of the collection cylinder near the through holes. A dust suction shell is threaded to one end of the collection cylinder. A filter screen is fixedly connected to one end of the sidewall of the dust suction shell. A rotating shaft is rotatably connected to the middle of the sidewall of the filter screen. A scraper is fixedly connected to the sidewall of the rotating shaft. The scraper has an L-shaped cross-section and works in conjunction with the filter screen.

[0009] As a preferred technical solution of this application, the dust inlet of the dust collection cylinder corresponds to the through hole.

[0010] As a preferred technical solution of this application, the inner cavity of the dust collection shell is fixedly connected to a motor for driving the rotating shaft to rotate.

[0011] As a preferred technical solution of this application, the vacuum cleaner fan is fixedly connected to the top of the inner cavity of the vacuum cleaner housing.

[0012] As a preferred technical solution of this application, the cross-section of the rubber sheet is triangular, and the tips of the multiple sets of rubber sheets are close to each other.

[0013] As a preferred technical solution of this application, the other end of the suction pipe is threadedly connected to a flexible hose, and one end of the flexible hose is fixedly connected to a suction head.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the scheme of this application:

[0016] 1. By setting a rotating shaft on one side of the filter screen and supporting the scraper through the rotating shaft, the L-shaped cross-section of the scraper allows the rotating shaft to clean the impurities on the surface of the filter screen when it drives the scraper to rotate. The impurities are temporarily stored in the scraper. Then, the centrifugal force generated by the rotation of the scraper causes the impurities to pass through the through holes and move into the dust collection cylinder, thereby reducing the occurrence of dust and other impurities clogging the filter screen and improving the dust removal effect of the dust cleaning device.

[0017] 2. By setting multiple sets of rubber sheets inside the collection cylinder, the cross-section of the rubber sheets is triangular, and the collection cylinder is sealed by the ring arrangement of the rubber sheets. When the vacuum cleaner blower is working, the tip of the rubber sheet will naturally open due to the wind force, so that the dust enters into the collection cylinder. When the vacuum cleaner blower stops working, the rubber sheet returns to its original closed shape, thereby preventing impurities from flowing back and increasing the efficiency of the dust cleaning device.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4A dust removal device includes: a suction pipe 100 and a suction fan 170 disposed at one end of the suction pipe 100. The suction fan 170 is used for dust removal. A collection cylinder 120 is threadedly connected to one end of the suction pipe 100. The collection cylinder 120 is used to collect dust and other impurities. Multiple sets of rubber sheets 121 are fixedly connected to the lower end of the inner cavity of the collection cylinder 120 to prevent backflow of impurities. Through holes 122 are provided at both ends of the inner sidewall of the collection cylinder 120. A dust collection cylinder 130 is threadedly connected to the sidewall of the collection cylinder 120 near the through holes 122. The through holes 122 cooperate with the dust collection cylinder 130 to collect dust. A suction shell 140 is threadedly connected to one end of the collection cylinder 120. The suction shell 140 is used to support a filter screen 150. The filter screen 150 is fixedly connected to one end of the sidewall of the suction shell 140. A rotating part is rotatably connected to the middle of the sidewall of the filter screen 150. A scraper 152 is fixedly connected to the side wall of the rotating shaft 151. The scraper 152 has an L-shaped cross-section and works in conjunction with the filter screen 150. Specifically, due to the rotation of the scraper 152, impurities are cleaned into the scraper 152. At this time, due to the rotation of the scraper 152, the impurities are subjected to centrifugal force and move towards one end of the scraper 152. When the scraper 152 moves to the through hole 122, the impurities will enter the dust collection cylinder 130. By setting a guide plate inside the scraper 152, the guide plate is a right-angled triangular block, so that when the impurities enter the scraper 152, they can move towards one end of the scraper 152 through the guide plate. The rotating shaft 151 drives the scraper 152 to rotate, and the scraper 152 scrapes away the dust. Due to the L-shaped setting, the dust slides into the inner cavity of the scraper 152 and enters the dust collection cylinder 130 through the through hole 122.

[0028] Please see Figure 2 The dust inlet of the dust collection cylinder 130 corresponds to the through hole 122. Dust is collected through the through hole 122 in conjunction with the dust collection cylinder 130. Specifically, both the collection cylinder 120 and the dust collection cylinder 130 are used to collect impurities. They are connected by threads, so that both the collection cylinder 120 and the dust collection cylinder 130 can be disassembled for easy handling of impurities. This is existing technology and will not be described in detail here.

[0029] Please see Figure 4 The inner cavity of the dust collection housing 140 is fixedly connected to a motor 160 for driving the rotating shaft 151 to rotate. Specifically, a breathable mesh is provided on the side of the dust collection housing 140 away from the dust collection pipe 100, and the rotating shaft 151 is driven to rotate by the motor 160.

[0030] Please see Figure 4 The vacuum cleaner fan 170 is fixedly connected to the top of the inner cavity of the vacuum cleaner housing 140, and vacuuming is performed by the vacuum cleaner fan 170.

[0031] Please see Figure 2The cross-section of the rubber sheet 121 is triangular, and the tips of multiple sets of rubber sheets 121 are close to each other. By setting multiple sets of rubber sheets 121, it is possible to prevent impurities from flowing back. Specifically, the rubber sheet 121 should be made of a material with moderate hardness and smooth surface, such as polytetrafluoroethylene, which can reduce the friction between the wire and the valve.

[0032] Please see Figure 1 and Figure 2 The other end of the suction pipe 100 is threadedly connected to a flexible hose 110. One end of the flexible hose 110 is fixedly connected to a suction head 111. The angle of the suction head 111 can be easily adjusted through the flexible hose 110, and the suction head 111 collects dust. Specifically, the flexible hose 110 is existing technology and will not be described in detail.

[0033] Specifically, when using this device, first connect the power supply to the dust cleaning device. The vacuum blower 170 generates suction on the vacuum pipe 100 and the vacuum head 111. The vacuum head 111, in conjunction with the flexible hose 110, draws the dust into the collection cylinder 120. At this time, due to the suction generated by the vacuum blower 170, the tip of the rubber sheet 121 begins to unfold, allowing impurities to enter the collection cylinder 120. Then, the motor 160 drives the rotating shaft 151 to rotate, which in turn drives the scraper 152 to rotate. The scraper 152 cleans the dust on the filter screen 150, and the dust, under the action of centrifugal force, enters the dust collection cylinder 130 through the through hole 122, thus completing the use of the device.
