Abstract

The utility model relates to a pressure dredger, composed of an operation guide handle, a diamond valve and a compression casing. The utility model is characterized in that the operation guide handle is provided with an air inlet and the lower end is a barrel-typed opening; the compression casing presents a tower-typed waviness and the upper end is provided with a concave cavity body whose bottom is provided with a convex cavity; the convex upper part is provided with an air inlet and the cavity bottom is provided with an open groove; the opening at the lower end is presents a cylindrical cone shape; the diamond valve is positioned in the convex cavity at the bottom of the concave cavity body at the upper end of the compression casing; the lower end of the operation guide handle is connected with the concave cavity body at the upper end of the compression casing, forming the pressure dredger. The dredger has the advantages of simple structure, convenient processing and use, big pressure, corrosion resistance and long service life.

Description

Pressure obstruction-removing device

The utility model is a kind of instrument that belongs to family, mediation lavatory, public place, sewer.

At present, be usually used in dredging sewer, closet swab, carry son etc., be a kind of simple tools, its utensil end opening is a plane shape of the mouth as one speaks, does not match with the shape of the mouth as one speaks of closet, sewer, leakage rate is big when suppressing, efficient is very low.Its versatility is poor, and pressure is little, weak effect, and pressure bowl rapid wear, application life is low.Useful dredging machine, but carry inconvenience, expense is higher, and the vast family of incompatibility uses.

The purpose of this utility model is to make a kind of Pressure obstruction-removing device, and its pressure is big, good airproof performance, and long service life, easy to operate, be suitable for using under the various places.

The utility model is led handle 1, rhombus valve 2, compression shell 3 by operation and is formed, as shown in Figure 1; It is characterized in that: the operation of hollow body is led on the handle 1 air inlet, and the bottom is the cartridge type opening; Compression shell 3 is tower ripple types, there is the matrix cavity upper end, the convex chamber is arranged at the bottom of its cavity, there is air inlet the convex upper end, fluting is arranged at the bottom of the chamber, and lower ending opening is the tubular cone-shaped, and rhombus valve 2 is arranged in the convex chamber at the bottom of the compression shell 3 upper end matrix cavitys, the bottom that handle 1 is led in operation connects the decomposition pressure dredging device with the matrix cavity of compression shell 3 upper ends.

Operating principle of the present utility model: Pressure obstruction-removing device divides upper and lower two parts, top be operation to lead handle 1 be hollow body, air inlet port is arranged above, the bottom is the cartridge type opening, can be into and out of gas.The bottom is a compression shell 3, and its shape is tower ripple type, and the housing pressure stretch spatial variations that contracts is big, and its housing lower ending opening is the tubular cone-shaped, can be with the closet of various not similar shapes, the mouth of a river connect down, and there is the matrix cavity upper end, and the inlet, outlet opening is arranged.Rhombus valve 2 is packed at the bottom of the chamber of matrix cavity of compression shell 3 upper ends in the convex chamber; Operation is led handle 1 lower end and is connected with compression shell 3 upper end matrix cavitys.During work, firmly handle is led in operation, and compression shell 3 is compressed, and at this moment the gas in the housing is pressed to all around and gone, when gas makes progress, promote rhombus valve 2 and move upward, make the interior convex top air inlet of matrix cavity of rhombus valve 2 closed compression housings, at this moment, the outlet that gas in the housing can only enter closet, sewer by lower ending opening, because tower ripple type housing compression stroke is big, can produce high pressure, repeatedly compression can be opened closet, dredging sewer.Lead handle 1 when moving up in operation, compression shell 3 elongations, the housing internal pressure reduces, and rhombus valve 2 falls, air inlet is gone up on convex on the matrix cavity of compression shell 3 upper ends top to be opened, at this moment, gas is entered in the hollow body by the air inlet on the lever body, and compressed housing 3 upper end air inlets enter in the compression shell 3, for compression next time provides condition, when compressing once more, can repeat above-mentioned action again, dredge closet, sewer.

The utility model compared with prior art, this dredging device is simple in structure, processing, easy to operate, can produce high pressure.Housing has corrosion-resistant, anti-aging, long service life are fit to the sewer in various places, the mediation of closet.

Description of drawings:

Fig. 1 is a general structure view of the present utility model;

Fig. 2 is the utility model Figure 1A-A profile.

Embodiment of the present utility model:

Pressure obstruction-removing device is led handle 1, rhombus valve 2 and pressure housing 3 by operation and is formed, as shown in Figure 1.Wherein, operation is led handle 1 usefulness plastics blow molding and is formed, and on the hollow handle body air inlet is arranged, and the bottom is the cartridge type opening, and there is screw thread on the surface, can connect with upper end, place, matrix chamber, compression shell 3 upper end.Plastic injection-moulded the forming of rhombus valve 2 usefulness, rhombus following connect cylinder and can insert at the bottom of compression shell upper end matrix cavity and the chamber in the grooved bore at the bottom of the convex chamber, as shown in Figure 1, 2.Compression shell 3 usefulness thermoplastic elastomer (TPE)s (SBS) are injection molded, and there is the matrix cavity body upper end, in screw thread is arranged, have the convex top of chamber that air inlet is arranged at the bottom of the chamber, matrix cavity body bottom surface has the groove of locating hole, as shown in Figure 1, 2, housing is tower ripple type, and lower ending opening is the tubular cone-shaped.

Rhombus valve 2 is pressed in convex chamber at the bottom of the compression shell 3 upper end matrix cavity body cavitys, and the lower end and the compression shell 3 upper end matrix cavity body thread connection of handle 1, decomposition pressure dredging device are led in operation.

During use, with the lower ending opening of Pressure obstruction-removing device aim at closet, sewer mouth bulldozing operation is led handle, can get through closet, sewer very soon after repeatedly.
