Abstract
An air filter with spiral meshing type internal and external protecting wire nets relates to an air filter. The utility model aims at solving the problem that the existing air filter has the disadvantage of weak pressure resistance. The air filter comprises a spiral meshing type internal wire net (4) and a spiral meshing type external wire net (5), wherein the spiral meshing type external wire net (5) is sleeved outside of the spiral meshing type internal wire net (4), an annular cavity is formed between the spiral meshing type external wire net (5) and the spiral meshing type internal wire net (4), both an upper end of the spiral meshing type external wire net (5) and an upper end of the spiral meshing type internal wire net (4) are fixedly connected with an upper end cover (1), both a lower end of the spiral meshing type external wire net (5) and a lower end of the spiral meshing type internal wire net (4) are fixedly connected with a lower end cover (2), and an annular filter body (3) is arranged in the annular cavity formed between the spiral meshing type external wire net (5) and the spiral meshing type internal wire net (4). The air filter of the utility model is applicable in automobile air filters.
Description
Technical field
The utility model relates to a kind of air-strainer, is specifically related to a kind of air-strainer that has the inside and outside protecting wire net of spiral mouth biting type.
Background technique
In the process of engine running, need combustion air, and contain sand usually in the air, foreign matter such as dust and steam, the problem of Yin Faing therefrom: one, after foreign matter enters the cylinder body of motor, cause the wearing and tearing of cylinder body easily; Two, enter in the engine motor oil when foreign matter, then may bring the heavy wear between the whole friction pair of motor; If the volume of three foreign matters is bigger, then might stop up the engine air throttle valve body, cause valve body work to have some setbacks.Therefore, in order to guarantee the normal operation of motor car engine, air must be through filtering, so that remove foreign matter before entering motor.Therefore, dispose air-strainer before the motor car engine usually.There is the weak shortcoming of anti-pressure ability in existing air-strainer, and what reason was that the protecting wire net of existing air-strainer adopts is that spot welding connects protecting wire net or vertical seaming protecting wire net.
The model utility content
The purpose of this utility model is in order to solve the problem a little less than there is anti-pressure ability in existing air-strainer, and then a kind of air-strainer that has the inside and outside protecting wire net of spiral mouth biting type is provided.
The technical solution of the utility model is: the air-strainer that has the inside and outside protecting wire net of spiral mouth biting type comprises upper end cap, lower end cap and ring-type filtration body; Described air-strainer also comprises protecting wire net and the outer protecting wire net of spiral mouth biting type in the spiral mouth biting type, the outer protecting wire net of described spiral mouth biting type is enclosed within the outside of protecting wire net in the spiral mouth biting type, and the coaxial setting of protecting wire net in outer protecting wire net of spiral mouth biting type and the spiral mouth biting type, form toroidal cavity between the protecting wire net in outer protecting wire net of spiral mouth biting type and the spiral mouth biting type, all fixedly connected with upper end cap with the upper end of the interior protecting wire net of spiral mouth biting type in the upper end of the outer protecting wire net of spiral mouth biting type, all fixedly connected with lower end cap with the lower end of the interior protecting wire net of spiral mouth biting type in the lower end of the outer protecting wire net of spiral mouth biting type, described ring-type is filtered body and is arranged in the toroidal cavity that forms between the protecting wire net in outer protecting wire net of spiral mouth biting type and the spiral mouth biting type.
The utility model compared with prior art has following beneficial effect: the utility model is by adopting protecting wire net and the outer protecting wire net of spiral mouth biting type in the spiral mouth biting type, improved the fastness of air-strainer, make the anti-pressure ability of air-strainer be improved, simultaneously ring-type is filtered body and played the conformal effect.In addition, the utility model also has simple in structure and advantage good filtration effect.
