Abstract

The utility model relates to an air cleaner consisting of a shell, a cover body with air inlets and a filter element arranged inside the shell. A clipping mechanism is arranged between the shell and the cover body. Because a clipping mechanism is arranged between the shell and the cover body, the clipping mechanism is thus designed that a positioning rotating axle is arranged on one end of the cover body, and a hanger is arranged on the other end. A handle is arranged on the shell and a trough is arranged at the relevant locations on the handle and at the hanger. The handle can rotate around a fulcrum of the handle, and a torsional spring is arranged on the handle fulcrum. When the air cleaner is to be maintained, the handle of the air cleaner needs merely a backward pull, causing the hanger to uncouple from the trough and the cover body of the air cleaner to open automatically. In this way, filter elements of all levels can be taken out conveniently for examination, cleaning or replacing when necessary.

Description

Air-strainer

Technical field:

The utility model relates to the air-strainer technical field; Be particularly related to a kind of air-strainer that is applicable to that miniature gasoline engine is used.

Background technique:

At present, in the air-strainer technical field, the structure of air-strainer is numerous.Air-strainer constitutes by housing, filter core and lid mostly.Air-strainer in use needs often cleaning and more renew cartridge, the cleaning of general air-strainer and change and all need pull down lid earlier and clear up and change, make more change jobs very inconvenient.Moreover the filtering effect of the filter core of existing air-strainer is undesirable.

Summary of the invention:

At above deficiency, the inventor proposed a kind of air filtering effective, change and the cleaning filter core is convenient, be applicable to the air-strainer that miniature gasoline engine is used.It comprises: housing, have the lid of inlet hole, be provided with filter core in the housing.Be provided with clamping mechanism between lid and housing.Owing to be provided with clamping mechanism between lid and housing, when the need maintenance, when safeguarding air-strainer, only need open clamping mechanism, air filter cover just can be opened, and the convenient filter core that takes out is checked maintenance.

In the utility model, described clamping mechanism is: lid one end is provided with positioning rotating shaft, and the lid the other end is provided with hook, and housing is provided with handle, is provided with the hook groove with the hook corresponding position on handle, and handle can rotate around its fulcrum, and the handle fulcrum is provided with torsion spring.When need maintain, when safeguarding air-strainer, only need collude the air-strainer handle backward, make hook throw off the hook groove, air filter cover is opened automatically, at this moment can take out filter cores at different levels easily and check, cleans or change in case of necessity.

In the utility model, described housing inboard is provided with the air conducting cover.Air guide sleeve can make air dispersion, enter Carburetor uniformly mixes with gasoline.

In the utility model, described lid positioning rotating shaft is located at the lid lower end, and the hook of lid is located at the lid upper end.Adopt this structure, because the effect of lid self gravitation, when colluding active handle, air filter cover can be opened automatically.

In the utility model, described filter core is arranged in order from inside to outside and is inner filter screen, papery filter core gummed part, air-strainer framework, thin sponge filter core, thick sponge filter core.Inner filter screen is combined by the steel wire of being located at the middle part and the screen cloth of being located at the steel wire outside.Adopt the filter core of this kind structure, can guarantee the air filtering effect.

Fig. 2 is the utility model lid schematic representation.

Fig. 3 is the utility model inner filter screen schematic representation.

Embodiment:

As Fig. 1, Fig. 2, shown in Figure 3: the air-strainer of present embodiment comprises: housing 1, have the lid 2 of inlet hole, be provided with filter core 3 in the housing.Lid one end is provided with positioning rotating shaft 4, and the lid the other end is provided with hook 5, and housing is provided with handle 6, is provided with hook groove 7 with the hook corresponding position on handle, and handle can rotate around its fulcrum 8, and the handle fulcrum is provided with torsion spring 9.The housing inboard is provided with air conducting cover 10.Filter core is arranged in order from inside to outside and is inner filter screen, papery filter core gummed part, air-strainer framework, thin sponge filter core, thick sponge filter core.Inner filter screen 11 is combined by the steel wire of being located at the middle part and the screen cloth of being located at the steel wire outside.

When air-strainer was worked, air was entered by the pore road of lid, filtered through thick, thin sponge filter core, papery filter core and inner filter screen, was made its dispersion, was entered Carburetor uniformly and mix with gasoline by the air conducting cover again.When air-strainer maintains, when safeguarding, only need collude the air-strainer handle backward, link up with the hook groove that disconnects handle, air filter cover is opened automatically, can take out filter cores at different levels easily and check, cleans or change.
