Blowing interface of blowing and sucking machine

Abstract

The invention discloses a blowing interface of a blowing and sucking machine in the field of mechanical interfaces, and the blowing interface is used for connecting an exhaust pipe of a blower and a pipe port of an extension pipe or a blowing and pressurizing nozzle. The invention is characterized in that the tail end of the exhaust pipe of the blower is in a taper pipe structure, and the inner diameter of the pipe port used for butt joint is ranged from the minimum outer diameter to the maximum outer diameter of the taper pipe; moreover, the outer surface of the taper pipe or the inner surface of the butt jointed pipe port at the tail end of the exhaust pipe is provided with a contact damping layer made of rubber or polyester. In the technical scheme of the invention, the pipe port at thetail end of the exhaust pipe is designed into a taper pipe, and is directly spliced and engaged with a pipe port of an external butt jointed component, so that the functions of the blowing and sucking machine can be conveniently and effectively switched, and the convenience of the use of the blowing and sucking machine is improved. In addition, the taper pipe structure and a preparation process thereof are simple and convenient, can effectively reduce the production cost and are beneficial to popularization and application.

Description

technical field [0001] The invention relates to a hose interface, in particular to an interface used for the butt joint work between the exhaust pipe of a blower and suction machine and peripheral accessories. Background technique [0002] The blower is an outdoor cleaning tool, mainly used for cleaning and collecting fallen leaves. It blows the leaves away by blowing air, or crushes the leaves by suction and puts them in bags. The existing leaf blower is increasingly designed towards the direction of multi-functional integration. By simply adding or reducing equipment components, the blower can be used to clean fallen leaves under various terrain conditions. The existing blowing and suction machines have entered the situation of hand-push operation, but due to different terrain conditions, the trolley cannot be pushed on a flat lawn, and can only rely on accessories such as extension pipes for supplementary cleaning. For relatively complex terrain conditions, and it is not...

Problems solved by technology

The existing blower has entered the situation of hand-push operation, but due to different terrain conditions, the trolley cannot be pushed on a flat lawn, and can only rely on accessories such as extension pipes for supplementary cleaning

For more complex terrain conditions, and it is not suitable for cleaning the plane first, and then cleaning the details, users often need to frequently replace the nozzles of peripheral components (extension pipes, blowing booster nozzles) that are connected to the exhaust pipe of the blower

However, the existing traditional blower interface generally adopts the structural design of buckle butt joint, which makes the replacement and use quite cumbersome, and brings great inconvenience to the heavy workload of leaf cleaning.
