Problems solved by technology
[0002] Existing dustproof masks are inconvenient to operate when replacing the filter element, and the filter element is unstable in the mask, and when the mask is used, the exhaust gas discharged will enter the filter cavity again and be discharged, which will consume the filter element and shorten the service time of the filter element. , when replacing the filter element, the vent of the mask is open, which makes it easy for the outside air to enter the mask without filtering.

The invention discloses a replaceable dustproof mask which comprises a mask body. A piece of partition cloth is fixedly arranged at the right end of the mask body, a soft cushion is fixedly arranged at the edge of the mask body, a tying belt is fixedly arranged at the right end of the soft cushion, an air inlet is formed in the left side of the mask body, the air inlet is provided with a moving groove is formed in a front and back communicated way, and a moving block is slidably arranged in the moving groove. The replaceable dustproof mask is simple in structure and convenient to operate, theair inlet is separated from an exhaust port, and the air inlet and the exhaust port are both provided with air one-way circulation devices, so that exhausted air is discharged out through the exhaustport and does not enter a filter cavity reversely to consume a filter element, the service time of the filter element is prolonged; furthermore, the filter element can be replaced, so that the mask issuitable for different occasions, and the mask is quick and convenient to use.
Description
technical field [0001] The invention relates to the technical field of daily necessities, in particular to a dustproof mask with a replaceable filter element. Background technique [0002] Existing dustproof masks are inconvenient to operate when replacing the filter element, and the filter element is unstable in the mask, and when the mask is used, the exhaust gas discharged will enter the filter cavity again and be discharged, which will consume the filter element and shorten the service time of the filter element. , When replacing the filter element, the vent of the mask is open, which makes it easy for the outside air to enter the mask without filtering. [0003] For this reason, it is necessary to further improve the dust-proof mask in the prior art, thereby improving the convenience of use and the dust-proof efficiency of the mask. Contents of the invention [0004] The object of the present invention is to provide a dustproof mask with a replaceable filter element,...
