Problems solved by technology

[0005] However, in such a dust collector hose in which the electric energy conducting wire 30 is separated from the reinforcing wire 20 in the hose, there is not only a problem that the overall weight of the hose increases, but also there is a problem that the electric energy conducting wire 30 cannot Risk of eventual damage due to long-term durability

Embodiment Construction

[0022] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0023] In the attached picture, Figure 1 to Figure 4 Shows the first embodiment of the present invention. figure 1 Indicates the partially cut-away state of the hose H. figure 2 Indicates the enlarged cross-sectional shape of the pipe wall portion, image 3 represents in exploded form the materials that make up the hose H, and Figure 4 Indicates the case where connecting pipes are connected to opposite ends. In the hose H, the pipe wall 1 having a helically wound shape is made of a material such as soft polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), or any other synthetic resin material, or rubber with the above-mentioned A mixture of any of the materials constitutes a material. The pipe wall 1 has an inner layer and an outer layer composed of an inner layer 3 and an outer layer 4, and 20 to 30 reinforcing threads 5 of nylon fi...

Abstract

A cleaner hose includes a synthetic resin pipe and four reinforcing hard steel wires disposed spirally, at predetermined intervals, in the synthetic resin pipe wall. The reinforcing hard steel wires are coated wires which are coated with synthetic resin. The pipe wall includes inner and outer layers in which an under wound tape and an upper wound tape are spirally wound while being displaced by half pitch from each other.

Description

technical field [0001] The present invention relates to a dust collector hose connected to an electric dust collector, and more particularly to a dust collector hose with a reinforcing wire wound helically on the inner side of the pipe wall formed of a synthetic resin material. Background technique [0002] The known construction of common dust collector hoses for electric dust collectors is such that the pipe wall forms a helical corrugation shape, and when the reinforcement wire is bare and uncoated, the reinforcement wire is enclosed in the corrugation of the pipe wall. The inner side of the corrugated ridge, or when the reinforcing wire has a resin layer, the wire is provided on the inner annular surface side of the corrugated ridge of the pipe wall. [0003] Such as Figure 5 As shown, as far as the latest electric dust collector is concerned, not only by turning ON-OFF the power switch on the main unit C of the electric dust collector to inhale air, but also by install...
