It is filtered the air in device.Existing mask filter structure has the following disadvantages, and patency is poor when air inlet, logical when influencing breathing
Smooth property, guard time are short.So as to cause poor filtration effect, and use cost is high.
Therefore, it is good that the utility model proposes a kind of passabilities, extends a kind of efficient active carbon filter cartridge of guard time.
Utility model content
The purpose of this utility model be it is existing insufficient in view of the prior art, propose that a kind of work efficiency is high and structure
Compact efficient active carbon filter cartridge.
The technical issues of the utility model is solved realizes a kind of efficient active carbon filtering using following technical scheme
Box, including upper housing and lower case, the upper housing and lower case are connected by buckle, and the buckle is located at lower case
On, the upper housing top is equipped with gas outlet, and diversion trench is equipped with below the gas outlet, be equipped in the diversion trench into
Gas grid, the diversion trench lower section is equipped with filter layer, and filter layer is located in upper housing, and the filter layer outer wall is equipped with ring
Shape protrusion, the annular protrusion top are equipped with small filtration members layer of charcoal, the annular protrusion lower section and filter layer by fastener
It is equipped with deflector at outer wall, baffle is equipped with below the filter layer, the baffle told is equipped with through mouth, and is equipped with more than one
It is a, diversion trench is equipped with below the baffle, the diversion trench is located in lower case, and the lower case bottom end is outlet
Mouthful, the gas outlet inner wall is equipped with reinforcing rib.
The deflector is an integral structure with annular protrusion, and the angle between deflector and annular protrusion is 80 degree
Angle.
The upper housing and lower case is circular configuration.
The gas outlet is equipped with internal screw thread.
The air-inlet grille is equipped with more than one.
The utility model has the following beneficial effects: proposing a kind of compact-sized efficient active carbon filter cartridge, work as gas
When blocking by encountering annular protrusion and deflector when active carbon and gap when tank wall, airflow obstruction, to change gas
Stream direction guiding active carbon is adsorbed.When the air-flow that first of blocker ring passes through encounters opposite direction rebound Shi Huibi, pass through
When second annular protrusion and deflector, carries out second and change airflow direction, select the flow direction of air-flow entirely through active carbon
It is adsorbed completely, with to can not adsorbed completely to avoid intermediate active charcoal, because of tank wall and active carbon loading density single-point
The problem of breakdown, can greatly improve the guard time of filtering；Since the inner wall of gas outlet is equipped with reinforcing rib, when in use,
Gas outlet can be more solid, reduces damaged probability；The utility model structure is simple, is skillfully constructed, using simple, convenient for pushing away
Extensively.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the partial enlarged view of the utility model.
Specific embodiment
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；In order to better illustrate this embodiment, attached
Scheme certain components to have omission, zoom in or out, does not represent the size of actual product；To those skilled in the art,
The omitting of some known structures and their instructions in the attached drawings are understandable.
Referring to attached drawing, a kind of efficient active carbon filter cartridge, including upper housing 2 and lower case 9,2 He of upper housing
Lower case 9 is connected by buckle 14, and the buckle 14 is located in lower case 9, and 2 top of upper housing is equipped with gas outlet 4,
It is equipped with diversion trench 3 below the gas outlet 4, air-inlet grille 5 is equipped in the diversion trench 3, is set below the diversion trench 3
There is filter layer 1, and filter layer 1 is located in upper housing 2,1 outer wall of filter layer is equipped with annular protrusion 6, the convex annular
Play 6 tops and small 15 layer of charcoal of filtration members be equipped with by fastener 16,6 lower section of the annular protrusion at 1 outer wall of filter layer equipped with leading
Flowing plate 7 is equipped with baffle 13 below the filter layer 1, and the baffle 13 told is equipped with through mouth 8, and is equipped with more than one, institute
Diversion trench 12 is equipped with below the baffle 13 stated, the diversion trench 12 is located in lower case 9, and 9 bottom end of lower case is
Port 10,10 inner wall of gas outlet are equipped with reinforcing rib 11.
