Description

A high-efficiency activated carbon filter cartridge

technical field

The invention relates to the technical field of gas masks, in particular to an efficient activated carbon filter box.

Background technique

When people exist in an environment with toxic gas or dust, in order to protect the human body, they usually wear a gas mask (mask) or a dust mask (hereinafter, the above articles that cover the human mouth are collectively referred to as masks) for protection. The mask filters the air inhaled by the human body through a filter structure. When in use, filter materials such as activated carbon are contained in a filter container to filter the air. The existing filter structure of the mask has the following disadvantages. The air intake is poor, which affects the air flow when breathing, and the protection time is short. As a result, the filtering effect is poor and the use cost is high.

Therefore, the present invention proposes a high-efficiency activated carbon filter box with good passability and extended protection time.

Contents of the invention

The object of the present invention is to propose a high-efficiency activated carbon filter box with high working efficiency and compact structure in view of the shortcomings of the existing technology.

The technical problem solved by the present invention adopts the following technical solutions to realize a high-efficiency activated carbon filter box, which includes an upper shell and a lower shell, and the upper shell and the lower shell are connected by buckles, and the buckles It is arranged on the lower shell, and the top of the upper shell is provided with an air outlet, and a diversion groove is arranged under the air outlet, and an air intake grill is arranged in the said diversion groove, and the said diversion groove A filter layer is provided below, and the filter layer is arranged in the upper casing. The outer wall of the filter layer is provided with an annular protrusion, and a small filter carbon layer is provided above the annular protrusion through the clip. The annular protrusion There is a deflector at the lower part and the outer wall of the filter layer, a baffle is provided under the filter layer, and there is more than one passage port on the baffle, and a guide is provided under the baffle. The flow groove, the flow guide groove is located in the lower casing, the bottom of the lower casing is an air outlet, and the inner wall of the air outlet is provided with reinforcing ribs.

The deflector and the annular protrusion are of an integral structure, and the included angle between the deflector and the annular protrusion is 80 degrees.

The upper shell and the lower shell are circular structures.

The air outlet is provided with an internal thread.

There is more than one air intake grille.

The beneficial effects of the present invention are: a compact and efficient activated carbon filter box is proposed, when the gas passes through the gap between the activated carbon and the tank wall and encounters the obstruction of the annular protrusion and the deflector, the air flow is blocked, thereby changing the The airflow direction is directed to the activated carbon for adsorption. When the airflow passing through the first barrier ring encounters the rebound in the opposite direction and returns to the wall, when it passes through the second annular protrusion and the deflector, the direction of the airflow is changed for the second time, and the flow direction of the selected airflow is completely carried out through the activated carbon. Adsorption, in order to avoid the incomplete adsorption of activated carbon in the middle, because of the problem of single-click penetration between the tank wall and the filling density of activated carbon, the protection time of filtration can be greatly improved; because the inner wall of the air outlet is provided with reinforcement ribs, when in use, the outlet The air port will be stronger and the probability of damage will be reduced; the invention has simple structure, ingenious conception, simple use and easy popularization.

Detailed ways

The accompanying drawings are for illustrative purposes only, and should not be construed as limitations on this patent; in order to better illustrate this embodiment, certain components in the accompanying drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art It is understandable that some well-known structures and descriptions thereof may be omitted in the drawings.

Referring to the accompanying drawings, a high-efficiency activated carbon filter box includes an upper casing 2 and a lower casing 9, the upper casing 2 and the lower casing 9 are connected by a buckle 14, and the buckle 14 is arranged on the lower casing On the body 9, an air outlet 4 is provided at the top of the upper housing 2, and a diversion groove 3 is arranged below the air outlet 4, and an air intake grill 5 is arranged inside the diversion groove 3. A filter layer 1 is provided under the diversion groove 3, and the filter layer 1 is arranged in the upper casing 2, and the outer wall of the filter layer 1 is provided with an annular protrusion 6, and the clamp 16 is passed above the annular protrusion 6 A small filter element 15 carbon layer is provided, a deflector 7 is provided at the bottom of the annular protrusion 6 and the outer wall of the filter layer 1, and a baffle plate 13 is provided below the filter layer 1, and the baffle plate 13 is provided with a There is a passage port 8, and there is more than one. A diversion groove 12 is provided under the baffle plate 13, and the diversion groove 12 is located in the lower casing 9. The bottom end of the lower casing 9 is The air outlet 10, the inner wall of the air outlet 10 is provided with reinforcing ribs 11.

The deflector 7 and the annular protrusion 6 are integrally formed, and the angle between the deflector 7 and the annular protrusion 6 is 80 degrees.

The upper casing 2 and the lower casing 9 are circular structures.

The air outlet 4 is provided with an internal thread.

There are more than one air intake grilles 5 .

A compact and high-efficiency activated carbon filter box, when filling the activated carbon, the carbon is packed according to the process requirements; when in use, the air enters the diversion groove 12 through the air outlet 10, and then passes through the passage on the baffle plate 13 The port 8 enters the filter layer 1, and the air is filtered by the activated carbon of the filter layer 1. When a small part of the air passes between the activated carbon and the inner wall, due to the action of the annular protrusion 6 and the deflector 7, the air is guided back to the filter layer. In the filter layer 1, prevent this part of the air from being unfiltered and improve the quality of filtration. After passing through the filter layer 1, it enters the diversion groove 3, and the air passes through the diversion groove 3 and is exported through the air outlet 4. Harmful gas enters from the air outlet 4, and the harmful gas enters the mask through the diversion groove after being filtered by activated carbon.

The present invention proposes a compact and high-efficiency activated carbon filter box. When the gas passes through the gap between the activated carbon and the tank wall and encounters the obstruction of the annular protrusion 6 and the deflector 7, the air flow is blocked, thereby changing the direction of the air flow. Activated carbon for adsorption. When the airflow passing through the first barrier ring encounters the rebound in the opposite direction and returns to the wall, when it passes through the second annular protrusion 6 and the deflector 7, the airflow direction is changed for the second time, and the flow direction of the airflow is selected to pass through the activated carbon as a whole. Adsorption is carried out completely to avoid the incomplete adsorption of the intermediate activated carbon. Due to the problem of single-click penetration of the tank wall and the filling density of activated carbon, the protection time of filtration can be greatly improved; When in use, the air outlet 10 will be stronger, reducing the probability of damage; the present invention has simple structure, ingenious concept, simple use and easy popularization.
