The first embodiment is as follows:

as shown in attached fig. 1 and 2, a powered breathing mask includes a mask body 1 and a filter tube 2 fixed on the mask body 1 by screws, wherein the filter tube 2 is a corrugated tube made of PE material. The cover body 1 comprises a visual plate and a cushion layer which is bonded and fixed on the visual plate, the cushion layer is made of flexible materials, the visual plate is made of transparent materials, for example: clear glass, and the like. The two sides of the upper part of the visible plate are integrally formed with fixing rings 11, the fixing rings 11 are provided with fixing holes, and fixing ropes (not shown in the figure) are fixed in the fixing holes through bolts. When the mask is worn, the mask body 1 is sleeved on the face of an operator, and the fixing rope is sleeved on the head of a medical worker. The cover body 1 is communicated with a one-way breather valve, the gas exhaled by medical personnel is discharged through the breather valve, and the external air can not enter the cover body 1 through the breather valve.

As shown in fig. 3 and fig. 4, a plurality of filter units are disposed in the filter pipe 2, preferably three filter units in this embodiment, each filter unit includes a power part 3 and a filter element 31, the power part 3 includes a casing 35 and a fan 32 located in the casing 35, a connecting piece 33 is disposed between the fan 32 and the casing 35, and two ends of the connecting piece 33 are respectively fixed on the casing 35 and the fan 32 through fastening bolts. The inside wall of casing 35 bonds and has fallen the layer of making an uproar, and the layer of making an uproar falls cotton 34 for making an uproar in this embodiment. The filter element 31 is sleeved on the right side of the casing 35, and the filter element 31 is fixedly bonded with the casing 35, in this embodiment, the filter element 31 is a filter layer, such as a mask fabric, and the filter element 31 reaches the standard of N95.

The fans 32 are electrically connected to a power supply, and the fans 32 in the present embodiment are all connected in parallel to the power supply, the power supply in the present embodiment is a battery pack 4, the battery pack 4 is three or four, preferably four, and each battery pack 4 is composed of eight dry batteries. The storage battery pack 4 is connected in parallel to provide 12V voltage to drive the fan 32 to work, a control module is electrically connected between the storage battery pack 4 and the fan 32, the control module is a control switch 41 in the embodiment, and the control switch 41 controls the on/off of the fan.

The specific implementation process is as follows:

first, the mask is worn on the face of the medical staff by the fitting of the fixing string and the fixing ring 11, and the cushion is fitted to the face of the medical staff to seal the mask.

Then, the control switch 41 is turned on, the storage battery pack 4 supplies power to the fan 32, the fan 32 sucks air into the casing 35 by overcoming the resistance of the filter element 31, the air is filtered by the filter element 31 and then sent into the casing 35, then the air is sent into the cover body 1 through the rear filter unit, and the air exhaled by medical staff is exhausted from the breather valve. When the fan 32 works, the fan 32 generates certain noise, and the noise generated by the fan 32 is reduced through the noise reduction cotton 34, so that the influence of the noise of the fan 32 on medical personnel is reduced.

As shown in fig. 3, in some cases, for example: after the filtering pipe 2 between the filtering unit at the lowest part and the filtering unit at the middle part is broken, the filtering unit at the middle part still filters the air entering the filtering pipe 2, so that even if the filtering pipe 2 is broken at partial position, the breathing mask in the embodiment can still be continuously used, and the defect that the filtering pipe 2 cannot be used once broken in the prior art is overcome.

Example two:

the difference between the second embodiment and the first embodiment is that, as shown in fig. 5, the battery pack 4 is electrically connected to the PCB 5, the fans 32 in the present embodiment are all connected to the PCB 5 in parallel, and the PCB 5 is electrically connected to the button switch 52. The PCB 5 is electrically connected with a detection unit, the detection unit comprises an IC chip and an LED lamp 51 electrically connected with the IC chip, and the LED lamp 51 is welded on the PCB 5. The IC chip is electrically connected to the battery pack 4 and detects the electric quantity information of the battery pack 4, and the IC chip causes the LED lamps 51 to light up by different amounts according to the electric quantity information.

Powered respirator still includes the controller, and the controller is the singlechip in this embodiment, and the singlechip electricity is connected with and is located the sensor that cover body 1 is internal, and the model of sensor is: a BOSCH BMP280 air pressure sensor.

The specific implementation process is as follows:

the sensor acquires the wind pressure information in the cover body 1, the sensor transmits the wind pressure information to the controller, the controller judges the wind pressure information after acquiring the wind pressure information, and if the wind pressure is too small, the controller controls the working power of the fan 32 to be increased, so that the air intake of the cover body 1 is increased; if the wind pressure is too large, the controller controls the working power of the fan 32 to be reduced, and then the intake air amount in the cover body 1 is reduced.

The wind pressure in the cover body 1 is detected, so that the air quantity in the cover body 1 can be prevented from being too much or too little, different working states of medical staff can be adapted, and the medical staff can feel more comfortable.

In the long-term use process of the fan 32, the electric quantity of the storage battery pack 4 gradually decreases, even the electric quantity of the storage battery pack 4 is insufficient, the fan 32 cannot work, and at this time, the storage battery pack 4 needs to be replaced. The detection unit acquires the electric quantity information of the storage battery pack 4 and displays the electric quantity information through the LED lamps 51, and if the electric quantity of the storage battery pack 4 is sufficient, all the LED lamps 51 are turned on; when the amount of electricity in the battery pack 4 gradually decreases, the number of the LED lamps 51 that light up decreases. Through the mode, medical personnel can judge the electric quantity of the storage battery pack 4 through the quantity of the LED lamps 51, and can replace the storage battery pack 4 in time.

The above is only a preferred embodiment of the invention, and it should be noted that, for those skilled in the art, it is possible to make several changes and modifications without departing from the inventive concept, and these should also be considered as the protection scope of the invention, which will not affect the effect of the implementation of the invention and the practicability of the patent. The techniques, shapes, and structural parts, which are omitted from the description of the present invention, are all known techniques.
