Description

Multi-tube blowing suction head

The invention relates to a dust collecting device, in particular to a multi-tube blowing suction brush head.

The technology industry or general industry must be equipped with dust collection equipment at the same time as processing and grinding equipment, so that the processing, grinding equipment and plant can maintain a better operating environment, which can improve product quality and maintain the health of operators .

Generally, the suction head installed in the vacuum equipment has a hollow shell shape or a tube shape, and the suction effect of the particulate dust and the dead corner of the equipment is not good.

According to the TW Certificate No. M552797 patent, a vacuum cleaner accessory includes a joint part which can be connected to a vacuum device (vacuum cleaner), and a brush head connected to the joint part. The brush head has a plurality of vacuum hoses. When the vacuum cleaner is started, the vacuum suction caused by the vacuum cleaner will use the suction hoses to suck up the dust.

Although this type of vacuum cleaner can produce a better vacuuming effect, it is still possible for the dust partially sunk in the low-lying depths, grooves, and slits in the condition that the entire brush head cannot be fully extended. Cannot produce better suction effect.

Therefore, an object of the present invention is to provide a multi-tube blowing suction head which can produce a better suction effect.

Therefore, the multi-tube blowing suction brush head of the present invention is suitable for being connected to a positive pressure source and a negative pressure source. The multi-tube blowing suction brush head includes a body, a plurality of suction tubes and at least one blowing tube. The body includes a first end, a second end opposite to the first end, a lead-out hole extending from the first end toward the second end and connected to the negative pressure source, and most of the The first end extends a suction hole that can communicate with the lead-out hole, and at least one blowing airflow path approaching the suction holes, the blowing airflow prop has a discharge end disposed on the second end, and an opposite The discharge end is connected to the lead-in end of the positive pressure source. The suction pipes are flexible and hollow in shape, and are respectively connected to the suction holes of the body. It is hollow and tubular, and is inserted into the discharge end of the air flow channel of the body.

The effect of the present invention is that the air blowing pipe is used to communicate with the positive pressure source, and a positive pressure air flow can be blown out, which can have an impact on the dust in low-lying depths, grooves, and slits, and then use the air suction pipes and The negative pressure source is connected and can generate a vacuum suction effect, can suck up the raised dust, and can achieve a better dust suction effect.

Referring to FIG. 1, FIG. 2 and FIG. 3, an embodiment of the multi-tube blowing suction brush head of the present invention is suitable to be connected to a positive pressure source 1 (for example, an air compressor. In order to make the drawing simple, the positive pressure source in FIG. 3 1 is represented by a square only), and a negative pressure source 2 (such as a vacuum cleaner, for the sake of simplicity in the drawing, the negative pressure source 2 in FIG. 3 is represented by only a square), the multi-tube blowing suction brush head includes a body 10. Most suction tubes 20, and a blowing tube 30.

The body 10 extends along an axis L, and includes a first end 111, a second end 121 opposite to the first end 111 along the axis L, a connecting member 11 corresponding to the first end 111, and a A positioning member 12 corresponding to the second end 121 is installed along one side of the connecting member 11 along the axis L. The connecting member 11 is a stepped hollow cylindrical shape, and has a small diameter section 112, a large diameter section 113 connected to one side of the small diameter section 112 along the axis L, and an opposite direction to the small diameter section 112 along the axis L. And a convex pipe section 114 connected to the other side of the large diameter section 113, and an outlet hole 115 provided along the axis L and extending from the convex pipe section 114 to the small diameter section 112, and the first end 111 is provided on the convex The pipe section 114 and the outlet hole 115 can be connected to the negative pressure source 2. The positioning member 12 has an outer end surface 122 corresponding to the second end 121, an inner end surface 123 opposite to the outer end surface 122 along the axis L, and a connection between a peripheral edge of the outer end surface 122 and a peripheral edge of the inner end surface 123. The outer peripheral surface 124, an inner hole 125 recessed from the inner end surface 123 and nested by the small diameter section 112, and most of the inhalation communicated from the outer end surface 122 to the inner hole 125 and can communicate with the outlet hole 115 A hole 126 and a blowing air passage 127 communicating from the outer peripheral surface 124 to the outer end surface 122. The suction holes 126 are in the shape of a stepped hole with a wide outer width and a narrow inner shape. The blowing air passage 127 has an inverted L shape and has a A discharge end 127 ′ disposed on the outer end surface 122 and an introduction end 127 ″ opposite to the discharge end 127 ′ and disposed on the outer peripheral surface 124 and connected to the positive pressure source 1.

The suction pipes 20 are flexible and hollow in shape, and are respectively inserted into the suction holes 126 of the body 10.

The air blowing pipe 30 is flexible and has a hollow tube shape, and is inserted into a discharge end 127 'of the air blowing passage 127 of the main body 10.

As shown in FIG. 3 again, by using the blow pipe 30 to communicate with the positive pressure source 1 and the role of the lead-out hole 115 to communicate with the negative pressure source 2, when the positive pressure source 1 and the negative pressure source 2 are activated at the same time By using the pressure airflow generated by the positive pressure source 1 to pass through the air blowing pipe 30, it can have an impact on the dust in the low-lying depths, grooves and slits (as shown by the solid arrow), and then use the negative pressure source 2 to generate Vacuum suction, these suction tubes 20 can then suck up the raised dust (as shown by the dotted arrow), and can achieve a better vacuuming effect, so for dead corners or low-lying depths, grooves, slits Dust can produce better absorption effect.

It is worth mentioning that even under the condition that the entire multi-tube blowing suction brush head of the present invention cannot be fully extended, the blow pipe 30 can be used to impact the dust in low-lying depths, grooves and slits, and then use the Waiting for the suction pipe 20 can suck up the raised dust and still achieve a better dust suction effect.

In summary, the multi-tube blowing suction brush head of the present invention has a simple overall structure, is easy to manufacture and assemble, and can produce a better dust suction effect, which can indeed achieve the purpose of the present invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited in this way, any simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the patent specification of the present invention are still Within the scope of the invention patent.
