Description

Technical Field

[0001] This utility model relates to the field of ventilation filters, and in particular to a novel ventilation filter. Background Technology

[0002] The function of ventilation filters in electrical cabinets is to provide fresh air for the equipment inside the cabinet to dissipate heat, while filtering dust, particulate matter and other pollutants from the air to keep the inside of the electrical cabinet clean.

[0003] Existing ventilation filters are very inconvenient to disassemble in practical applications, making it time-consuming and laborious to maintain or replace the filter cotton later. Moreover, the dust removal effect of the filter cotton in some current ventilation filters is poor. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a novel ventilation filter.

[0005] The novel ventilation filter provided by this utility model adopts the following technical solution:

[0006] A novel ventilation filter includes a housing 1, a housing 2, and a primary filter cotton. The bottom of the housing 1 is hinged to the bottom of the housing 2, and the top of the housing 1 is inserted into the top of the housing 2. The primary filter cotton is disposed inside the housing 1 and the housing 2. The housing 2 is provided with an inclined air inlet plate, and the air inlet plate is provided with a deflector. The housing 1 is provided with a plurality of air inlet grilles. The primary filter cotton is provided with a plurality of microporous channel units, and the plurality of microporous channel units are provided with particle capturing protrusions.

[0007] Optionally, the microporous channel unit is serrated, with serrated plates arranged in parallel, forming a channel in pairs.

[0008] Optionally, the bottom of the second housing is provided with a circular slot, and the bottom of the first housing is correspondingly designed with a connector. The connector is inserted into the circular slot, and the first housing is hinged to the second housing through the connector. The connector rotates within the slot.

[0009] Optionally, the housing is provided with a connector, and a corresponding slot is provided at the top of the housing, into which the connector is inserted.

[0010] Optionally, the slot has insertion holes on its two side walls, the connector has protrusions, and the connector is a plastic elastic element.

[0011] Optionally, the back of the housing is provided with a connection port, and a fastener is provided at the connection port. The fastener is an elastic plastic part, and the housing is detachably connected to the cabinet through the connection port and the fastener.

[0012] In summary, this utility model has at least one of the following beneficial technical effects:

[0013] 1. It greatly increases the adsorption area of ​​the primary filter cotton. When the airflow carrying particulate pollutants flows parallel through the adsorption plate, the airflow is constantly turbulent under the action of the sawtooth adsorption plate. Under the action of inertial force, the particulate pollutants are thrown onto the particle capture protrusions. After contacting the particle capture protrusions, they are adsorbed by the adsorption material, thereby achieving the purpose of separating particulate pollutants from the airflow and greatly improving dust removal efficiency.

[0014] 2. The second housing is detachably connected to the first housing. Simply insert your finger into the lever of the second housing and pull the lever outward to separate the connector at the top of the first housing from the slot at the top of the second housing. At this point, the pre-filter can be removed for replacement or cleaning. After replacement, rotate the second housing and insert the connector into the slot to secure it. This solution is more efficient and convenient, achieving quick separation through the cooperation of the connector and the slot, as well as the connection between the bottoms of the first and second housings.

[0025] This utility model discloses a novel ventilation filter. (Refer to...) Figure 1-6 A novel ventilation filter includes a housing 1, a housing 2, and a primary filter 3. The bottom of housing 1 is hinged to the bottom of housing 2, and the top of housing 1 is inserted into the top of housing 2. The primary filter 3 is disposed within housing 1 and housing 2. Housing 2 has an inclined air inlet 4 with a lever 5. Housing 1 has several air inlet grilles 6. The primary filter 3 contains several microporous channel units 7, which are serrated with parallel serrated plates arranged in pairs. A channel is formed, and several microporous channel units 7 are provided with particle-capturing protrusions 8. Through this design, the adsorption area of ​​the primary filter cotton 3 can be greatly increased. When the airflow carrying particulate pollutants flows parallel through the adsorption plate, the airflow is constantly turbulent under the action of the sawtooth adsorption plate (which disrupts the airflow pattern). Under the action of inertial force, the particulate pollutants are thrown onto the particle-capturing protrusions 8. After contacting the particle-capturing protrusions 8, they are adsorbed by the adsorption material, thereby achieving the purpose of separating particulate pollutants from the airflow and greatly improving dust removal efficiency.

The connector 10 is inserted into the circular slot 9, and housing 1 is hinged to housing 2 via the connector 10. The connector 10 rotates within the slot. A connector 11 is provided on the housing, and a slot 12 is correspondingly provided at the top of housing 2. The connector 11 is inserted into the slot 12. Insertion holes 13 are provided on the two side walls of the slot 12. The connector 11 is provided with protrusions 14. The connector 11 is a plastic elastic element. In this way, housing 2... For the detachable connection of housing 1, simply insert your finger into the lever 5 of housing 2 and pull the lever 5 outward to separate the connector 11 at the top of housing 1 and the slot 12 at the top of housing 2. At this time, the pre-filter cotton 3 can be taken out for replacement or cleaning. After replacement, rotate housing 2 and insert the connector 11 into the slot 12 to fix it. This solution is more efficient and convenient. Through the cooperation of connector 11 and slot 12, as well as the connection between the bottom of housing 1 and housing 2, quick separation is achieved.

[0027] The back of the housing 1 is provided with a connection port 15, and a fastener 16 is provided at the connection port 15. The fastener 16 is an elastic plastic part. The housing 1 is detachably connected to the cabinet through the connection port 15 and the fastener 16. Through this design, the back of the housing 1 and the cabinet can be quickly connected or separated.
