The purpose of the utility model is to provide a heatable air supply mask, which aims to solve the problem that the cold air irritates the user when the existing air supply mask is used in low temperature weather, and the water vapor is easy to condense on the inner filter layer of the mask.
In order to achieve the purpose of the utility model, the utility model provides a heatable air supply mask, which includes a mask body, an air supply device, a heating layer, a filter layer and a power supply device;
The mask body is provided with a penetrating first opening;
The air blowing device is installed on the outside of the mask body and includes a micro fan, and the micro fan is directly facing the first opening;
The heating layer is attached to the inside of the mask body and is a mesh structure woven by electric heating wires;
The filter layer is located inside the heating layer and is detachably provided on the mask body;
The power supply device is connected to the air blowing device and the heating layer through a circuit.
Further, the knitting density of the heating layer facing the first opening is greater than the knitting density of other positions.
Further, the working temperature of the heating layer is 35 to 37°C
Further, a breathing valve that draws air toward the inside of the mask is provided in the first opening, and the air blowing device is installed on the breathing valve.
Further, the lithium battery of the power supply device is installed on the air blowing device.
Further, a power supply interface is provided on the air supply device, and the power supply device is connected to the air supply device through the power supply interface.
Further, the filter layer is provided with a one-way valve for venting air toward the outside of the mask, the heating layer is provided with a mesh for the one-way valve to pass through, and the mask body is provided with a one-way valve for passing through Set the second opening.
Further, the heatable air blowing mask further includes an elastic sealing ring arranged on the inner edge of the mask body, and the elastic sealing ring is used to be arranged on the user's face.
Further, the elastic sealing ring includes a face contact end and a connecting end; the face contact end is used to be arranged on the user's face, and the connecting end is used to connect with the inner edge of the mask body.
Further, the opposite end of the connecting end of the elastic sealing ring and the face also includes a flange extending toward the center of the mask body, a groove is formed between the flange and the mask body, and the groove is used for clamping The edge of the filter layer.
The heatable air blowing mask of the present invention heats the air delivered by the air blowing device by setting a heating layer.
