In the description of the embodiment, the operator is used as a reference, and the direction close to the operator is a proximal end, and the direction away from the operator is a distal end.

As shown in fig. 1 to 6, the high efficiency filter for a canister includes a housing 1 having a cavity therein and a tubular filter body 2 disposed in the housing 1. The shell 1 can be integrally formed by injection molding of materials such as plastics and metals, and can also be formed by assembling multiple parts. The filter body 2 can be any of various known filter elements, such as tubular filter sponge, filter paper, etc. The utility model discloses in right casing 1 and the material of crossing filter body 2 do not restrict and give unnecessary details.

As shown in fig. 1 to 3, the housing 1 is composed of a main body 13 and an upper cover 14, and the main body 13 and the upper cover 14 are connected by clipping or screwing. That is main part 13 with upper cover 14 can be dismantled, and both connected modes are in the utility model discloses in preferably adopt the joint to realize, for example, the outer wall of main part 13 is close to open-top's region and is formed with the boss the inner wall of upper cover 14 is formed with the draw-in groove, and the boss can be fixed in the draw-in groove, and its connected mode of course also can be other feasible modes, for example their interference fit connects, perhaps splices etc. and does not do not describe here any more.

As shown in fig. 5, the diameter of the filter body 2 is smaller than the diameter of the inner wall of the housing 1, so that a gas flow chamber 102 for accommodating gas is formed between the outer wall of the filter body 2 and the inner wall of the housing 1. The airflow chamber 102 communicates with a first duct 11 provided in the side wall of the housing 1, and the inner chamber 21 of the filter body 2 communicates with a second duct 12 formed in the housing 1. Therefore, the gas entering from the second pipeline 12 into the inner cavity of the filter body 2 can enter the airflow cavity 102 after being filtered by the filter body and is discharged from the first pipeline 11; of course, the gas can also enter from the first pipe 11 and exit from the second pipe 12.

Further, the first duct 11 is eccentrically disposed on the side wall of the main body 13, which is advantageous in that: when the first pipeline 11 is taken as an air inlet pipe, an air outlet of the first pipeline 11 is positioned at a gap between the shell 1 and the filter body 2, so that the blockage of the filter body 2 to the entering air flow can be reduced, and the air inlet rate is improved to improve the filtering efficiency; at the same time, the gas flow can be more uniformly distributed in the gas flow cavity 102, so that the gas and the whole surface of the filter body 2 can fully exert the performance

The height of the filter body 2 is smaller than that of the shell 1, a dust collecting groove 103 for collecting dust and impurities is formed between the bottom end of the filter body 2 and the bottom end of the shell 1, and the dust collecting groove 103 is positioned below the filter body 2, so that the filter body is not blocked by the filtered dust and impurities when the filter body works, meanwhile, the deposited dust is not easy to enter the airflow cavity due to the blocking of the installation structure of the filter body 2, and the condition that the deposited dust flies under the action of airflow can not occur.

As shown in fig. 2 to 3, a ring of ribs 131 are provided on the outer surface of the main body 13, parallel to each other and extending in a direction parallel to the axis of the main body. The reinforcing ribs 131 can effectively prevent the main body 13 from being scratched or even broken due to the impact of crushed stones. The outer wall of the main body 13 is also formed with a connecting member 132 to which other mechanisms are connected. The upper surface of the connecting member 132 is a smooth plane, and the lower surface thereof is formed with an inclined surface inclined toward the upper surface thereof; a notch is provided on the side of the connecting member 132 away from the inclined surface for connection with other mechanisms.

The upper surface of the upper cover 14 is formed with a groove 141 near the edge thereof, and the groove 141 can facilitate the application of force to the upper cover 14, i.e. the grasping or the detachment or the installation of the upper cover from the main body 13.

As shown in fig. 1, two circles of bosses 142 for fixing and limiting the filter body 2 are concentrically arranged on the lower surface of the main body 13 and/or the upper cover 14, and the width between the two circles of bosses 142 is equal to the thickness of the pipe wall of the filter body 2. That is, the boss 142 is used for fixing and limiting the filter body 2, the boss 142 is preferably arranged on the main body 13 and the upper cover 14, so that the filter body 2 can be better fixed, and the filter body is guaranteed not to shake in the using process.

As shown in fig. 2, a pagoda-shaped joint is formed on the first duct 11. The connector can be conveniently and quickly connected with other pipelines. Of course, the structure of the connector is not unique, and the connector can be screwed, so the connection mode is not limited in the present invention. In the present novel usage, a pagoda shape is preferably used.

Referring to fig. 1 and 6, the second pipeline 12 includes a first vertical branch section 121 and a second vertical branch section 122, and the first branch section and the second straight section are connected by an arc-shaped section 123. The radian of the arc-shaped pipe section 123 can be adjusted according to actual requirements, so that the problem that the airflow is blocked to reduce the airflow rate due to the fact that air is blocked when flowing from the first straight pipe section to the second straight pipe section due to the right-angle relation between the air and the second straight pipe section can be effectively solved. As shown in fig. 2 and 4, at least one clamping groove 124 is formed at the inner wall of the inlet of the second pipe 12. The clamping groove 124 includes a sliding groove 1241 extending from the inlet of the second pipeline inward for a certain distance, the inner end of the sliding groove is connected with an arc-shaped groove 1242 extending along the circumferential direction of the second pipeline, and one end of the arc-shaped groove far away from the sliding groove extends to the outer surface of the second pipeline. The external pipe can be inserted into the inlet of the second pipe 12 through the clamping groove 124; after the external pipeline is inserted into the second pipeline 12 through the sliding slot 1241, the external pipeline is rotated until the clamping block of the external pipeline is clamped and fixed with the arc-shaped slot 1242. Thus, the two can be mutually limited and can not fall off.

The utility model has a plurality of implementation modes, and all technical schemes formed by adopting equivalent transformation or equivalent transformation all fall within the protection scope of the utility model.
