Detailed Description

This patent is described in further detail below with reference to the accompanying drawings:

referring to fig. 1-4, the present invention provides an embodiment of an atomizer mask, which comprises a mask body 1, wherein the mask body 1 comprises a mask main body 3, and the mask main body 3 is provided with a mask hanging rope hole 6 and a mask air inlet 8. Above-mentioned face guard main part 3 sets up the flexible limit of face guard 4 for hard material one shot forming's an organic whole structure on face guard main part 3's periphery, and the gas tightness is realized to the face skin that the flexible limit of face guard 4 can laminate the wearer to provide comfortable face and touch and feel. A flexible edge connecting part 5 is arranged on the mask main body 3 around the mask air inlet 8, and the flexible edge connecting part 5 is connected with the mask flexible edge 4. A flexible sealing edge 9 is arranged on the inner side surface of the mask main body 3 corresponding to the nose part of a wearer, and the flexible sealing edge 9 comprises a brim-shaped top part and two side protective wings of which the two ends extend downwards. Wherein the brim-like top portion is adapted to be resiliently deformed against the bridge of the nose and its periphery under the influence of the bridge of the nose of the wearer, the wings on either side are adapted to be resiliently deformed against the nasal rim and the wings, and the entire flexible sealing edge 9 is adapted to prevent the aerosolized aerosol and the breath-generated gases from escaping from the vicinity of the nose of the wearer. The flexible edge 4, the flexible edge connecting part 5 and the flexible sealing edge 9 of the mask are of an integrated structure made of flexible materials.

Specifically, the method comprises the following steps: the flexible sealing edge 9 and the flexible edge 4 of the mask are integrally formed, the wings on two sides of the flexible sealing edge 9 are two thin sheets arranged in a splayed shape, the middle sections of the edges extending downwards of the two thin sheets are arc-shaped, and the middle sections of the edges gradually transition to be tangent with the flexible edge of the mask close to the bottom. This is designed to provide more reliable contact of the flexible seal 9 with the bridge and edge of the wearer's nose when the mask is worn by the user, and to provide better consistency over repeated wear. The flexible sealing edge 9 has a pre-deformed edge, which is equivalent to defining the deformation direction of the flexible sealing edge 9. In addition, the edge of the flexible edge 4 of the mask is provided with edge predeformation. In this way, the flexible edge 4 and flexible seal 9 of the mask are better able to conform to the skin or nose of the face for air tightness and provide a more comfortable face contact.

In practice, the visor-like top and the wings on both sides of the flexible sealing edge 9 are both lengthened appropriately to ensure that different nose types are matched, i.e. for wearers with high nose bridges or large noses the flexible sealing edge 9 deforms more elastically, for wearers with low nose bridges or small noses the flexible sealing edge 9 deforms less elastically, but still ensures the fit with the nose so as to ensure airtightness and comfort.

Preferably, the flexible edge 4, the flexible edge connecting part 5 and the flexible sealing edge 9 of the mask are all formed by injection molding of medical silica gel, thermoplastic elastomer (TPE) or thermoplastic polyurethane elastomer (TPU); the mask body 3 is made of transparent hard plastic by injection molding.

Still further, a mask air inlet 8 is arranged in the middle of the mask main body 3, a mask air outlet 7 is arranged at the lower part of the mask main body 3, a one-way valve 2 is arranged on the mask air outlet 7, and the one-way valve 2 is opened only when the wearer exhales and is used for discharging waste gas generated by breathing of the wearer. The one-way valve 2 is closed when the wearer inhales, ensuring that the user is fully inhaling the incoming aerosolized aerosol particles from the mask air inlet 8.

Still further, the check valve 2 is detachably mounted on the mask air outlet 7, the check valve 2 is provided with a check valve fixing buckle 2.1, the mask air outlet 7 is provided with a check valve fixing groove 10, and the check valve fixing buckle 2.1 is clamped into the check valve fixing groove 10 to fix the check valve. As shown in fig. 4, in particular, the check valve 2 is provided on the outer side of the mask body 3, so that the installation operation is convenient.

The air inlet 8 of the mask is directly connected with the mist outlet of the atomizing cup of the atomizer or is connected with the mist outlet of the atomizing cup of the atomizer through an air conveying pipe. Preferably, the mask air inlet 8 is a tubular structure with a suddenly changed tube diameter, and the tube diameter of the mask air inlet 8 at least comprises two specification sizes (for example, the inner diameter of a thin section is 20 mm, and the inner diameter of a thick section is 22 mm), and is used for being compatible with at least two standard tube diameters of the mist outlet of the atomizing cup. The face mask hanging rope holes 6 are two holes, inconvenience that a hanging rope can be fixed only by knotting under the condition of a single hole is avoided, and the hanging rope can be fixed on the face mask only by penetrating the hanging rope through the two holes of the face mask hanging rope holes 6.

The utility model discloses an atomizer face guard when concrete implementation, adopts the preparation of double-colored injection molding process, face guard main part 3 is one color, adopts the preparation of the transparent material of stereoplasm, and the flexible limit 4 of face guard and flexible seal edge 9 are the dichromatic, adopt the preparation of flexible material, the material that adopts one color and dichromatic can be mutually soluble. The outer side face of the mask main body 3 is provided with a flexible material spreading channel which can be designed into other patterns such as geometric patterns or cartoon patterns, so that the flexible material can flow and fill along the patterns of the flexible material spreading channel in the injection molding process of the mask flexible edge 4, and finally, a flexible edge connecting part 5 connected with the mask flexible edge 4 is formed. The pattern of the flexible edge connecting part 5 can make people more easily accept the atomization mask, and is also helpful for relaxing the mood of the user and improving the compliance of atomization therapy. Moreover, the manufacturing can be completed at one time in the manufacturing and forming process of the atomizer face mask by adopting a double-color injection molding process, and the production of the atomizer face mask is simple and efficient.
