Description

Technical Field

[0001] The utility model relates to a detachable dust suction device for woodworking machines. Background Art

[0002] Construction and decoration projects often require carpenters to hold electric hand drills or electric hand saws to drill or saw on materials such as density boards, fiberboards or wood panels. Drilling and sawing produce a lot of wood chips and dust, which pollutes the environment and affects the health of workers.

[0003] The Chinese utility model with the authorization announcement number CN211028196U on July 17, 2020 discloses a new type of drilling machine, including a main unit and an outer cover. In the utility model, an outer cover is arranged outside the drill bit, and a dust extraction pipe arranged on the side of the outer cover is connected to a dust suction fan installed in the handle. When the dust suction fan is running, the dust in the outer cover can be extracted. An air inlet is arranged on the right inner wall of the outer cover. When the dust suction fan is running, the dust brought by the drill bit will be lifted by the air entering from the air inlet, and fly in the outer cover until it is sucked in by the dust extraction pipe.

[0004] The dust suction fan of the new drilling machine is arranged in the handle, and the dust suction pipe is passed into the handle through the main machine and connected to the air inlet of the dust suction fan. Such a structure determines that the dust suction fan and dust suction pipe are small in size and have weak suction force. In addition, it lacks a wind-dust separation device and a dust collecting container, and can only remove a small amount of dust, so it is not very practical.

[0005] The Chinese utility model with the authorization announcement on June 3, 2022 and the announcement number CN 216653935 U discloses a new dust suppression device for civil engineering construction, which includes a base plate, the top of which is fixedly connected with a support mechanism, a water storage tank, a mounting frame and a push plate in sequence, the top of the push plate is fixedly connected with a controller, a cyclone separator is fixedly installed in the mounting frame, and a storage box is arranged directly below the bottom discharge port of the cyclone separator. The utility model controls the operation of the negative pressure fan through the controller. Under the action of the negative pressure fan, external air enters the cyclone separator through the air inlet funnel, the cyclone separator removes dust from the air, and the dust-removed air is discharged through the negative pressure fan, and the dust is discharged into the storage box from the discharge port at the bottom end of the cyclone separator. At the same time, the water pump draws out the water in the water storage tank, transports it to the first water spray mechanism and the second water spray mechanism through a hose, and sprays it out by the atomizing nozzle. The combined effect of the sprayed water and the cyclone separator greatly reduces the dust content in the air.

[0006] The air intake funnel of the device cannot be connected to the electric hand drill or the electric hand saw and can only be placed next to the drill bit of the electric hand drill or the saw blade of the electric hand saw. It cannot completely cover the drilling or sawing area, and dust always escapes, so the dust removal effect is limited. Summary of the invention

[0007] The technical problem to be solved by the utility model is how to overcome the above-mentioned defects of the prior art and provide a detachable dust suction device for woodworking machines and tools.

[0008] In order to solve the above technical problems, the present detachable woodworking machine dust suction device comprises a centrifugal fan and a dust hood, and is characterized in that: it also comprises a cyclone separator, a dust box and a trolley, the centrifugal fan and the dust box are arranged on the trolley, the cyclone separator is arranged above the dust box, the lower opening of the cyclone separator leads into the dust box, the air outlet of the cyclone separator is communicated with the inlet of the centrifugal fan through a ventilation pipe, the dust hood is in the shape of a cone tube, the side wall of the dust hood is provided with a dust suction interface, the dust suction interface is connected to the air inlet of the cyclone separator through a hose with a supporting ring or a supporting spiral keel, the small end interface of the dust hood can be sleeved on the head shell of the equipped woodworking machine, and is provided with a clamp or a clamp, the large end interface of the dust hood is connected with a telescopic hose, and the telescopic hose is provided with an elastic spiral keel.

[0009] The dust cover is preferably made of an elastic transparent material, and the tube wall of the telescopic hose is preferably made of a transparent silicone material, so that it is easy to observe drilling and sawing. The elastic spiral keel structure is the same as the spiral spring.

[0010] Before use, put the small end of the dust hood on the head shell of the matching woodworking tool, so that the drill bit or saw blade extends into the dust hood and the telescopic hose, and then use a clamp or a hoop to fix the dust hood and the head shell of the matching woodworking tool together. Figure 1 shown.

[0011] Then start the centrifugal fan, and cover the lower end of the telescopic hose on the board to be drilled or sawed, and then turn on the matching woodworking tools (electric hand drill such as CN202130148597.5 electric pistol drill or electric hand saw such as CN95208053.2 electric hand saw), hold the matching woodworking tools and press down to drill or saw. The elastic spiral keel on the telescopic hose can provide support for the telescopic hose to prevent it from being sucked down by the centrifugal fan; on the other hand, the telescopic hose can maintain a certain elasticity and has a good sealing and dust removal effect.

[0012] The dust and wood chips generated during drilling or sawing are passed through the dust hood along with the air, through a hose with a support ring or a supporting spiral keel, and into the cyclone separator. After the cyclone separator, the dust and wood chips fall into the dust collecting box under the influence of gravity. The dust-removed air is sucked out by the centrifugal fan and discharged into the atmosphere.

[0013] This design has strong suction power, good dust removal effect and high dust holding capacity.

[0014] As an optimization, the small end interface of the dust hood is also equipped with a plurality of elastic adjustment sleeves, which can be individually or collectively sleeved on the head shell of the woodworking tool, and then sleeved by the small end interface of the dust hood. The elastic adjustment sleeve is preferably made of rubber. With such a design, if the diameter of the head shell of the woodworking tool is too thin or too small, several elastic adjustment sleeves can be sleeved on it to make it suitable for sleeved with the dust hood.

[0015] The utility model discloses a detachable woodworking machine dust suction device with strong suction force and good dust removal effect, and is suitable for use by woodworkers at construction sites. BRIEF DESCRIPTION OF THE DRAWINGS
