Description

Technical Field

[0001] This utility model relates to the field of air purification device technology, specifically a medical negative pressure isolation air purification device. Background Technology

[0002] An air purifier is an electrical device that removes pollutants from the air through technologies such as filtration, adsorption, and decomposition. It is mainly used to improve indoor air quality. A medical negative pressure isolation air purifier is a high-efficiency purification device specifically designed to control the airflow and prevent the spread of pollutants. The internal air pressure of the purifier is lower than that of the outside, ensuring that air can only flow into the device in one direction, thus preventing internal pollutants (such as viruses, bacteria, and dust) from leaking into the external environment.

[0003] During air purifier use, the power output may be adjusted depending on the ambient size and required purification time. However, common air outlets are fixed and the airflow cannot be adjusted. Therefore, we propose a medical negative pressure isolation air purification device to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a medical negative pressure isolation air purification device to solve the problems mentioned in the background art.

[0006] As a further technical solution of this utility model, the holes and slots are equally spaced on the outside of the upper air outlet, the upper air outlet is inserted into the upper mounting slot on the top of the main body, the sliding block is set on the front and rear ends on both sides of the bottom of the upper air outlet, and the sliding block at the bottom of the upper air outlet slides with the inside of the sliding groove on the inner side of the upper mounting slot.

[0007] As a further technical solution of this utility model, an air inlet mesh group is provided on the outside of the main body, a fixed base is installed inside the air inlet mesh group, a negative pressure fan is installed inside the fixed base, a filter base is installed at the bottom of the negative pressure fan, a pre-filter layer is provided on the outside of the filter base, a HEPA filter layer is provided on the inside of the pre-filter layer, an activated carbon layer is provided inside the HEPA filter layer, an external UV lamp is installed on the outside of the main body, and an internal UV lamp is installed inside the main body.

[0008] As a further technical solution of this utility model, the filter seat is connected to the negative pressure fan inside the fixed seat, and the filter seat is provided with a pre-filter layer, a HEPA filter layer and an activated carbon layer in sequence inside the filter seat. The air inlet mesh group is connected to the filter seat inside the main body through the main body.

[0009] As a further technical solution of this utility model, a dust collection base is provided at the bottom of the main body, an upper fixing groove is provided at the top of the dust collection base, a dust collection groove is provided at the top of the dust collection base, and a support base is installed at the bottom of the main body.

[0010] As a further technical solution of this utility model, the dust collection base is connected to the support base at the bottom of the main body, the support base carries the dust collection base and is connected to the bottom of the main body, the upper fixing groove at the top of the dust collection base is engaged with the bottom of the filter seat, and a dust collection groove is provided at the top of the dust collection base.

[0011] Compared with the prior art, the beneficial effects of this utility model are: this medical negative pressure isolation air purification device not only realizes the air outlet regulation function and the multiple filtration function, but also realizes the installation and collection function;

[0012] (1) By setting the air outlet adjustment structure, the present invention is beneficial in that: when in use, the upper air outlet is inserted into the upper mounting groove on the top of the main body, and the sliding blocks on the front and rear ends of the bottom of the upper air outlet are slidably engaged with the sliding blocks inside the upper mounting groove. By sliding the sliding blocks inside the sliding groove, the upper air outlet can extend and retract at the top of the main body, thereby increasing the exposure of the holes and grooves outside the upper air outlet, thus realizing the air outlet adjustment function.

[0013] (2) By setting up a multi-filtration structure, the present invention is beneficial as follows: When in use, the filter seat is installed inside the main body and inserted into the upper fixing groove at the top of the dust collection base. The negative pressure fan inside the top fixing seat of the filter seat is connected. After the negative pressure fan is started, the air is drawn into the main body through the air inlet mesh group and comes into contact with the filter seat. The air is filtered and adsorbed through the pre-filter layer, HEPA filter layer and activated carbon layer inside the filter seat. The air is discharged through the upper air outlet at the top of the main body. Then, the internal UV lamp and external UV lamp inside and outside the main body disinfect the inside of the main body and the current environment to increase the safety of the use of the main body, thereby realizing the multi-filtration function.

The negative pressure fan 9 inside the top fixing seat 10 of the filter seat 11 is connected. After the negative pressure fan 9 is started, air is drawn into the main body 3 through the air inlet mesh group 5 and comes into contact with the filter seat 11. The air is filtered and adsorbed through the pre-filter layer 15, HEPA filter layer 16 and activated carbon layer 17 inside the filter seat 11. The air is discharged through the upper air outlet 1 on the top of the main body 3. Then, the internal UV lamp 8 and external UV lamp 4 inside and outside the main body 3 disinfect the inside of the main body 3 and the current environment to increase the safety of the use of the main body 3, thereby realizing the multi-filtration function.

[0028] A dust collection base 12 is provided at the bottom of the main body 3. An upper fixing groove 19 is provided at the top of the dust collection base 12. A dust collection groove 18 is provided at the top of the dust collection base 12. A support base 6 is installed at the bottom of the main body 3.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, by setting up an installation and collection structure, the support base 6 and the dust collection base 12 are integrated into one unit. When in use, the support base 6 carrying the dust collection base 12 is inserted into the bottom of the main body 3, so that the upper fixing groove 19 on the top of the dust collection base 12 is engaged with the filter seat 11. When in use, after the primary filter layer 15 on the outside of the filter seat 11 filters dust and impurities, the dust will fall into the dust collection groove 18 on the outside of the dust collection base 12 for collection, thereby realizing the installation and collection function.

[0031] Working principle: When in use, the upper air outlet 1 is inserted into the upper mounting groove 7 on the top of the main body 3. The sliding blocks 13 on the front and rear ends of the bottom of the upper air outlet 1 are slidably engaged with the sliding blocks 13 inside the upper mounting groove 7. By sliding the sliding blocks 13 inside the sliding groove 14, the upper air outlet 1 can extend and retract at the top of the main body 3, thereby increasing the exposure of the holes and grooves 2 outside the upper air outlet 1. When in use, the support base 6 and the dust collection base 12 are integrated. The support base 6 carrying the dust collection base 12 is inserted into the bottom of the main body 3, so that the upper fixing groove 19 on the top of the dust collection base 12 is engaged with the filter seat 11.
