Problems solved by technology

[0003] The N95 mask can isolate smaller particles, and its filtration efficiency for particles with an aerodynamic diameter of 0.075 μm ± 0.02 μm reaches more than 95%. The aerodynamic diameter of air bacteria and fungal spores varies between 0.7-10 μm, which is A variety of airborne bacteria and fungal spores are also within the protection range of the N95 mask, and the N95 mask fits more closely with the face, and it is not easy to leak air from the periphery. It causes difficulty in breathing for users, and even dizziness due to lack of oxygen, especially for the elderly and children with weaker constitutions, a face protection device that can protect the user's face and breathe smoothly has emerged as the times require
[0004] Existing face protection includes breathing masks and air-filtering ventilators, such as those made by Honeywell, Scott Technologies, and 3M Innovations, all of which share common features : The production cost is high, and it cannot be used once. When the ventilator is used for the second time, it needs to be disinfected and used again. However, it is easy to carry out secondary pollution to the mask during disinfection, which reduces the safety of using the mask.

Embodiment 1

[0039] Substantially attached figure 1 Attachment figure 2 Attach image 3 As shown, a disposable electric air filter ventilator, including a filter and a guide structure mounted in the filter, such as attached Figure 4 As shown, the filter is a filter plate 5, and the filter plate 5 reaches N95 standard, and the longitudinal section of the filter plate 5 is rectangular in the present embodiment.

[0040] The guide wind structure includes a fan 62, a casing 61, and a battery pack 8 (not shown), the model of the fan 62 in this embodiment is: 4028 fan, the fan 62 is fixed to the casing 61 by bolts, the casing 61 The filter plate 5 is connected, and the fan 62 communicates with a noise reduction structure 3. In the present embodiment, the noise reduction structure 3 includes a noise reduction pad 32 and the outer casing 31, and the noise reduction cotton 32 is bonded to the outer casing 31. The outer casing 31 is in communication with the casing 61, and the outer casing 31 is fixed to...

Embodiment 2

[0048] The difference between the first example and the first example is that Figure 5 As shown, the battery pack 8 is electrically connected to the PCB plate 72, and the PCB plate 72 is electrically connected to the switch control module. In this embodiment, the switch control module is controlled switch 71, and the PCB plate 72 is electrically connected to the detection module, the detection module is IC. The chip, IC chip is electrically connected to several LED lights 73.

[0049] The fan 62 is electrically connected to the controller. In this embodiment, the controller is a single chip microcomputer, and the controller is electrically connected to a sensor located within the video board 12, and the sensor of the sensor is: the air pressure sensor of the BOSCH BMP280.

[0050] The specific implementation process is as follows:

[0051] The sensor acquires the wind pressure information in the mask 1, and the sensor passes the wind pressure information to the controller, and the...

Embodiment 3

[0055] The third embodiment is different from the first example, Image 6 As shown, the noise reduction structure 3 includes a housing 31, the left end opening of the outer casing 31, and the right end of the outer casing 31 communicates with the air tube 33; the left end of the outer casing 31 is connected to the fan through the bolt.

[0056] A first-order noise reduction layer is provided on the inner wall of the outer casing 31, and the first-order noise reduction layer includes sound absorbing cotton 34 and the first sound absorbing plate 35, and the sound absorbing cotton 34 and the first sound absorbing plate 35 are arranged in the outer wall of the outer casing 31 in the outer casing 31. The sound absorbing cotton 34 is bonded to the inner wall of the outer casing 31, and the first sound absorbing plate 35 is bonded to the sound absorbing cotton 34, and both ends of the first sound absorbing plate 35 are fixed to the inner wall of the outer casing 31. The first sound absorb...

Abstract

The invention relates to the technical field of medical and health protection, and discloses a disposable electric air filter respirator, which includes a filter and a mask connected to the filter; an air guide mechanism is installed in the filter; the air guide mechanism includes a fan and is electrically connected to the fan The battery pack is equipped with a noise reduction structure connected with the mask on the fan. The invention has a simple structure, is convenient for medical personnel to use, has low cost, can be recycled directly after use, does not need to be used again, and reduces the risk of reusing the ventilator.

Description

Technical field [0001] The invention relates to the field of medical and health protection, and more particularly to a disposable electric air filter ventilator. Background technique [0002] Social industrialization and urbanization progress make smog are more common, as well as social emergency infectious diseases, at which time the face needs to take protective measures, facial protective measures are mainly carried out by wearing masks, and the mask pairs PM2.5 or above Pollutants and others carry the foam of the bacteria for isolation, currently, the best mask products are the N95-shaped mask. [0003] The N95-shaped mask can isolate smaller particles, which have a particle of 0.075 μm ± 0.02 μm in diameter to 95% or more, and the air dynamic diameter of air bacteria and fungal spore varies between 0.7-10 μm. Air bacteria and fungal spores are also within the protection range of the N95-shaped mask, and the N95-shaped mask is combined with the facial fit, which is not easy t...
