Abstract

The invention discloses a mask with a range broadening function. The mask comprises a mask body and a first one-way air valve arranged on the mask body. Ventilation is conducted on the outer side of the mask through the first one-way air valve and is stopped on the inner side. The mask is characterized in that a second one-way air valve is arranged on the mask body, and ventilation is conducted on the inner side of the mask through the second one-way air valve and is stopped on the outer side; one end of an air pipe is connected with the second one-way air valve in a sealed manner, and the other end of the air pipe communicates with a hollow omega-shaped neck sleeve; and a filter is arranged at each of the two ends of the omega-shaped neck sleeve. According to the mask, the filters are externally arranged and communicated through the air pipe, and the size limit disadvantage is well solved; and furthermore, the two one-way air valves independent of each other are arranged on the mask, the good light and thin performance is kept for the mask body, the filters can be carried more conveniently due to the design of the neck sleeve, and the mask is especially suitable for the outdoor work.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a mask with an enlarged filtering range. Background technique [0002] The simple breathing mask of the prior art is provided with a filter on the main body of the mask, and this design, due to the limitation of size, has a poor filtering effect. In addition, the filter volume is relatively small, and the filter element needs to be replaced frequently. Coupled with the one-way air valve, while keeping the main body of the mask light and thin, the technical requirements are relatively high. Contents of the invention [0003] The object of the present invention is to provide a mask with a large filtering volume to overcome the problem of poor filtering effect due to the limitation of the filter volume. [0004] The present invention provides a mask with enlarged filtering range, comprising: a mask main body and a first one-way air valve arranged on the mask main...
