Problems solved by technology
[0003] The current electric air-supply respirator is used together with welding goggles. When using it, the user cannot know the working status of the electric air-supply respirator in real time, such as air flow, power, filter blockage status, etc. The user must estimate Or measure the remaining power to ensure there is enough estimable time to complete the welding task
This could be a failure of the power supply during a complex welding process, because if the welding is not completed within the st

Embodiment 1
[0028] Such as Figure 1-2 As shown, an electric air supply air filter 1 includes a hollow housing 2, the housing 2 is provided with a blower motor 3, an air filter element 4 and a battery 5, and the housing 2 is also provided with a PCB board 6 , the battery 5 is electrically connected to the PCB board 6 , and the PCB board 6 is electrically connected to the wireless receiving unit module 7 and the hypoxia sensor 30 . The hypoxic sensor 30 can detect the level of oxygen content in the air, and when the oxygen content is lower than a certain threshold, a hypoxic alarm sound will be sent.
[0029] As another implementation, the PCB board 6 is electrically connected to the USB port and the hypoxic sensor 30. Of course, in addition to the USB port, other existing wired connection ports can be used, such as signal connection through a USB data cable.
[0030] As the third implementation mode, the PCB board 6 is electrically connected with the hypoxia sensor 30, the wireless recei...

The invention relates to the technical field of electric air supply air filters, electric welding variable-light goggles, and controller devices of the electric air supply air filters and the electric welding variable-light goggles, in particular relates to an electric air supply air filter, electric welding variable-light goggles, and a controller of the electric air supply air filter and the electric welding variable-light goggles. Compared with the prior art, the controller is in signal connection with the electric air supply air filter and the electric welding variable-light goggles in a wireless, wired or wireless and wired combined manner to control the electric air supply air filter to work; meanwhile, information of air flow rate and electric quantity can be seen from a screen of the electric welding variable-light goggles; the content of oxygen in air can be detected by a low oxygen sensor, when the content of the oxygen is lower than a threshold value, a low-oxygen alarm warning tone can be generated, and meanwhile, an 'O2!' icon of a display screen of the controller flashes to generate a low-oxygen warning signal to be sent; the air flow rate and the electric quantity can be seen from the electric welding variable-light goggles, so that the working state of the electric air supply air filter can be learned by a user in real time without picking an electric air supply breather from the waist; and therefore, the work efficiency can be greatly improved.
Description
technical field [0001] The invention relates to the technical field of an air filter, electric welding light-changing goggles and a control device thereof, in particular to an electric air supply air filter, electric welding light-changing goggles and a controller thereof. Background technique [0002] Welders are hazardous types of work. Welders are inevitably placed in an environment with a large amount of harmful substances during operation. The dust and toxic gas particles in the smoke are extremely small, and long-term exposure is very harmful. Therefore, major companies have invested a lot of money To develop new protective devices to improve the breathing environment of welders. Now the common ones are electric air-supply breathing devices to improve the breathing environment of welders and ensure the health of welders. Air-purifying respirators are for users It is a protective device made from dust and harmful gases in certain industries and manufacturing processes. ...
