Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon barrel filters, in particular to an activated carbon barrel filter for an air conditioning ventilation system. Background Art

[0002] The main functions of an air conditioning ventilation system are to provide the oxygen required for human breathing, dilute indoor pollutants or odors, remove pollutants generated in the indoor process, remove the excess heat or moisture in the room, and provide the air required for indoor combustion. It is mainly used in buildings such as homes, commercial buildings, hotels, and schools. The air conditioning ventilation system has become a standard configuration in modern buildings. While people enjoy a comfortable space, when the air conditioning ventilation system extracts air, it will inhale harmful gases, odors, organic substances, heavy metal ions, etc. floating in the air. At this time, harmful substances will enter the building, affecting the user experience. Currently, activated carbon is placed on the inlet side of the air conditioning ventilation system to purify the incoming air.

[0003] In the existing air purifier that uses activated carbon to filter air, after being used for a period of time, the filtering function of the activated carbon gradually declines and needs to be replaced. However, the common air filters on the market have a complex structure and are integrally installed, making the replacement difficult. When the activated carbon loses its filtering function, only the filter can be selected for replacement, which is a waste. In addition, the utilization rate of activated carbon in the existing air filters is poor, and the utilization rates of activated carbon in different parts are different. When replacing, all the activated carbon needs to be replaced, which is also a waste. Summary of the Utility Model

Detailed implementation manner

[0025] As Figures 1 to 9 shown, in this embodiment, the utility model includes a connecting seat 1 formed with a plurality of positioning holes 11 and several filter cartridge groups 2. The several filter cartridge groups 2 are respectively snap-connected to the several positioning holes 11 in one-to-one correspondence. Each filter cartridge group 2 includes a barrel body 21, a filter layer 22, a filter material 23, and a cover 24. One end of each barrel body 21 is snap-connected to the positioning hole 11. A chute 211 is formed along the length direction inside each barrel body 21. The filter layer 22 is slidably connected to the barrel body 21 through the chute 211. The first end of the filter layer 22 is in supporting cooperation with the bottom of the barrel body 21. Both free ends of the filter material 23 are in pressing cooperation with the filter layer 22 and are arranged between the barrel body 21 and the filter layer 22 along the length direction of the barrel body 21. The cover 24 is magnetically attached to the other end of the barrel body 21. The cover 24 is formed with a pressing portion 241, and the pressing portion 241 is in pressing cooperation with the second end of the filter layer 22;

[0026] The connecting seat 1 is installed on the air inlet side of the air conditioning ventilation system. Multiple groups of filter cartridge groups are used as pre-filters to remove pollutants in the air entering the system. Among them, the filter cartridge group adopts a cylindrical structure. With a number of first ventilation holes 213 provided on the barrel body 21 and a number of second ventilation holes 223 provided on the filter layer 22, the cylindrical design makes the overall structure compact after installation. The first ventilation holes 213 and the second ventilation holes 223 can suck in external air to a greater extent. The structure of the filter material 23 is activated carbon non-woven fabric, which has good adsorption performance, uniform thickness, good air permeability, and the activated carbon particles are not easy to fall off. It preliminarily filters and adsorbs the inhaled gas. A filter material is placed in the first cavity of the filter layer 22. The filter material is activated carbon particles, which perform secondary filtration on the entering gas. The filter material 23 and the filter material are used to double-filter and adsorb the impurities contained in the gas by a dual-filtering and adsorbing structure. Moreover, the filter material 23 and the filter material use activated carbon material, which has a large specific surface area and can efficiently adsorb harmful substances in the air, improving the purification and filtration effect;

[0027] The filter medium 23 is inserted between the filter layer 22 and the barrel body 21 from the opening side of the barrel body 21, and is tightly fitted by the limiting block 224 of the filter layer 22. The wavy filter medium 23 has more mesh holes than a flat filter screen, improving the filtration efficiency. Moreover, due to the increase in the number of mesh holes, the service life of the filter screen can be extended, the maintenance frequency can be reduced, and the installation is convenient and efficient. The feeding port 244 structure provided in the middle of the cover 24 communicates with the first cavity. After the cover 24 is magnetically fixed, the staff only needs to pull out the feeding plug 242 to replace the filter material in the first cavity, enabling the quick replacement of the filter medium 23 and the filter material, simplifying the work process, and improving the work efficiency.

[0028] In this embodiment, a plurality of first support portions 212 are provided on the inner wall of the barrel body 21 along the circumferential direction, and the plurality of first support portions 212 are arranged at equal intervals. A plurality of second support portions 221 are provided on the outer wall of the filter layer 22 along the circumferential direction, and the plurality of second support portions 221 are arranged at equal intervals.

The plurality of first support portions 212 and the plurality of second support portions 221 are both in supporting cooperation with the filter medium 23. The first support portions 212 and the second support portions 221 alternately form a wavy channel. After the filter medium 23 is placed, the plurality of first support portions 212 and the plurality of second support portions 221 respectively form a pushing and supporting effect on both sides of the filter medium 23, ensuring that the shape of the filter medium 23 remains stable during operation and is not easily deformed under the action of air flow.

[0029] In this embodiment, the barrel body 21 is provided with a plurality of first ventilation holes 213, locking grooves 214, and a plurality of first magnetic members 215. The plurality of first ventilation holes 213 are all arranged on the side wall of the barrel body 21. The locking grooves 214 are arranged at the bottom of the barrel body 21 and are in snap-fit connection with the positioning holes 11. The plurality of first magnetic members 215 are arranged at the upper end of the barrel body 21 and are magnetically attached to the cover 24. The first ventilation holes 213 are used to adsorb external air. The locking grooves 214 are in a right-angled shape. The locking grooves 214 are provided with a snap-fit portion and a sliding portion. One end of the sliding portion is provided with a connecting slope, and the connecting slope is connected to the snap-fit portion. The other end of the sliding portion forms a sliding-out groove, and the sliding-out groove is connected to one end of the barrel body 21 for the locking block 114 to withdraw. The depth of the snap-fit portion is greater than the depth of the sliding portion, and it is in snap-fit and limit with the lower part of the locking block 114, simplifying the installation process.

[0030] In this embodiment, the filter layer 22 is provided with a slider 222, a plurality of second ventilation holes 223 and two groups of limiting blocks 224. The slider 222 is arranged on the outer side of the filter layer 22 along the length direction and is slidably connected to the chute 211. The plurality of second ventilation holes 223 are equidistantly arranged on the side wall of the filter layer 22. The diameters of the plurality of second ventilation holes 223 are all smaller than the diameters of the plurality of filter materials. The two groups of limiting blocks 224 are respectively arranged on both sides of the slider 222 and are used for limiting and pressing the filter material 23. The diameters of the plurality of second ventilation holes 223 are all smaller than the diameters of the plurality of first ventilation holes 213, reducing the air flow rate entering the first cavity, enabling the filter material to more fully adsorb pollutants in the air and improving the adsorption and filtration effect. The two groups of limiting blocks 224 are used for pressing and cooperating with both sides of the filter material 23 to reduce the vibration amplitude of the filter material 23 under the push of the air flow.

[0031] In this embodiment, the cover 24 is provided with a feeding plug 242 and a plurality of second magnetic members 243. A feeding port 244 with a gradually increasing diameter is formed in the middle of the cover 24. The feeding plug 242 is formed with a limiting head 245, and the limiting head 245 is in limiting cooperation with the feeding port 244. The bottom surface of the feeding plug 242 is attached to the cover 24. The plurality of second magnetic members 243 are all arranged on the bottom surface of the cover 24 and are magnetically attached to the barrel 21. The discharge port with a gradually increasing diameter from top to bottom facilitates the staff to pour out the filter material from the first cavity and improves the replacement effect of the filter material. The plurality of second magnetic members 243 are magnets. Through magnetic positioning and installation, the installation process is simplified and the installation efficiency is improved. During use, with magnetic adsorption and cooperation with the air flow, the cover 24 can be stably installed and fixed on the barrel 21. The lower end of the feeding plug 242 is made of rubber material, which has good elasticity and sealing performance and can be in interference fit with the feeding port 244 to achieve the effect of extrusion sealing.

[0032] In this embodiment, a plurality of the positioning holes 11 are formed with mounting holes 111. The mounting holes 111 are correspondingly arranged on the side walls of the positioning holes 11. A guiding rod 112 is arranged in the mounting holes 111. The connecting seat 1 is further provided with an elastic member 113 and a locking block 114. The elastic member 113 is sleeved on the guiding rod 112. The locking block 114 is slidably connected to the mounting holes 111. One end of the locking block 114 is formed with a pushing groove and is connected to the elastic member 113. The other end of the locking block 114 is snap-fitted with the barrel body 21. With the structure of the locking block 114 and the elastic member 113, when the barrel body 21 is placed into the positioning hole 11, the inclined surface of the mounting hole 111 contacts the side wall of the barrel body 21, and the locking block 114 moves backward. At the same time, the elastic member 113 is compressed by force. After placing, the barrel body 21 is rotated. The front end surface of the locking block 114 contacts the side wall of the barrel body 21 until it rotates to one side of the locking groove 214 of the barrel body 21. The locking block 114 is pushed out under the resilience of the elastic member 113 and is snapped into the locking groove 214. The barrel body 21 is continuously rotated until the locking block 114 enters the engaging portion of the locking groove 214, completing the locking of the barrel body 21. When withdrawing, the barrel body 21 is rotated unidirectionally, so that the locking block 114 moves along the sliding portion of the locking groove 214, and the locking block 114 withdraws along the sliding-out groove, releasing the locking. The structure of the locking block 114 and the elastic member 113 is used to limit the barrel body 21. The structure is simple and convenient to use. The mechanical structure is locked and fixed, reducing the need for daily maintenance.

[0033] In this embodiment, an inclined surface is formed on one side of the locking block 114 connected to the barrel body 21.

[0034] In this embodiment, the filter medium 23 is wavy and is arranged between a plurality of the first support portions 212 and a plurality of the second support portions 221.

[0035] The working principle of the present utility model:

[0036] Before use, install the filter layer 22 into the barrel body 21 along the sliding groove 211. The bottom of the filter layer 22 abuts against the bottom of the barrel body 21. The filter medium 23 is inserted into the wavy channels alternately formed by the first support portion 212 and the second support portion 221 along the opening on one side of the barrel body 21. Both ends of the filter medium 23 are tightly fixed by two groups of limit members of the filter layer 22. Subsequently, magnetically install the cover 24 at one end of the barrel body 21. The pressing portion 241 of the cover 24 is in pressing fit with the upper part of the filter layer 22. Open the feeding plug 242 of the cover 24 and add the filtering material into the first cavity along the feeding port 244. After the addition, re-insert the feeding plug 242. When the barrel body 21 is placed into the positioning hole 11, the inclined surface of the mounting hole 111 contacts the side wall of the barrel body 21, and the locking block 114 moves backward. At the same time, the elastic member 113 is compressed under force. After placing it, rotate the barrel body 21. The front end surface of the locking block 114 contacts the side wall of the barrel body 21 until it rotates to one side of the locking groove 214 of the barrel body 21. The locking block 114 is pushed out under the resilience of the elastic member 113 and snaps into the locking groove 214. Continue to rotate the barrel body 21 until the locking block 114 enters the engaging portion of the locking groove 214 to complete the locking of the barrel body 21;

[0037] When the barrel body 21 is withdrawn, rotate the barrel body 21 unidirectionally to make the locking block 114 slide along the sliding portion of the locking groove 214. The locking block 114 exits along the sliding-out groove, and the barrel body 21 can be taken out after unlocking.

[0038] Although the embodiments of the present utility model are described with actual solutions, they do not constitute a limitation to the meaning of the present utility model. For those skilled in the art, the modifications to its implementation solutions according to this specification and the combinations with other solutions are obvious.
