Description

Mask support with fixing mechanism

Technical Field

The present application relates to a mask support placed between a planar mask and a human face to support the mask.

Background

When the novel coronavirus is subjected to pneumonia, the mask becomes an important epidemic prevention material, wherein the plane mask is widely accepted due to simple production, convenient carrying and low price, but the plane mask is directly used and has the following inconvenience: the mask has the advantages that the ventilation area is reduced due to the large binding face of the mask, the mask is easy to stick to the mouth and the nose during air suction, and the problem is solved well by using the support inside the mask. The mask support directly matched with the plane mask in the patents with application numbers of CN201830478074.5, CN201830214623.8, 201730527369.2 and CN201720069521.1 has the following disadvantages: 1. the nose structure has the advantages that the fitting between the nose bridge ribs and the nose of the plane mask is influenced, and air leakage is easy. 2, wrap up the mouth nose in the laminating face with face laminating part for an annular, the position of wearing is predetermined by the facial profile that assumes during the design, causes the discomfort of wearing easily, can't satisfy different age ethnic demands. 3. The mask can not be simply and independently connected with the plane mask into a whole so as to avoid the falling of the bracket when the mask is taken off. 4. The mask and the support cannot be pulled at the chin to expose the mouth and the nose. The aim of the present application is to overcome the above drawbacks, in whole or in part, while ensuring lightness and high breathability of the stent.

Detailed Description

The structure of the mask support of the present application will be described with reference to the accompanying drawings,

figure 1 is a general view of a mask support.

Fig. 2 is a schematic view of the stand worn on a human body, for convenience of description, the directions are clearly shown in fig. 2, in the figure, 51 is a nose portion, 52 is a mouth portion, the direction of the product is defined by the visual angle of a user, the front of the user is front, the right of the user is right, and the upper is up when the user uses the stand. As can be seen from fig. 1 to 4, the support mainly supports the space under the nose and in front of the mouth, and comprises a contact surface 4 which is approximately U-shaped in front view and is contacted with the face of a person, a support surface 2 which supports a fabric layer of the mask to prevent the mask from being directly contacted with the mouth and the nose, a hollow part 5 which is arranged behind the support surface and provides space under the nose and in front of the mouth, a hollow part 1 which accommodates the nose, and a vent hole 3, wherein the support surface 2 is composed of vertical ribs 21 and transverse ribs 22. At the end periphery of 4 there is a cuff formation 41. The contact surface 4 and the support surface 2 form a bracket body. Avoiding the formation of indentations in the face is also feasible as a simple variation, changing the U-shape of the contact surface to a discontinuous U-shape or a partial facet support. In this embodiment, the supporting surface and the attaching surface are preferably made of plastic, and the thickness is preferably 0.6-1.2mm, so that the supporting surface has good flexibility and supporting capability, and no indentation is formed on the opposite portion.

Fig. 5 to 9 are the first embodiment, and in this embodiment, based on the example of fig. 1 to 4, two left and right fastening mechanisms for hooking the mask are added. The same parts as in the examples of fig. 1-4 will not be described again here. The fastening mechanism is composed of an elastic mechanism and an elastic fixing mechanism 42, the elastic mechanism is a special-shaped spring 43 in the example, a front end 432 of the spring is abutted against the elastic fixing mechanism 42, and a clamping hook 433 extends out of a rear end 431 of the spring towards the front 432 of the spring. When no external force is applied to the fixing portion as shown in fig. 7, the hook 433 connected to the rear end 431 of the spring and the front end 432 of the spring are both abutted against the elastic fixing mechanism 42, and fig. 8 is a state diagram of the spring at this time. Fig. 9 is a schematic view showing the mask attachment side being held, in which the hooks 433 are extended by the foreign object pressing against the rear end 431 of the spring, the fabric 60 on the mask attachment side is put between the hooks and the elastic fixing means, and the mask and the bracket are connected by releasing the pressing against the rear end 431 of the spring.

Fig. 10 and 11 show a second embodiment, in which another fastening mechanism 44 is added at 2 points based on the example of fig. 1-4, and the same parts as those in the example of fig. 1-4 are not described again here. The fastening mechanism 44 is composed of an elastic mechanism and a clamping mechanism, and in this example: the elastic mechanism is a spring 445, one end of the spring 445 is abutted against the fixing part 446, the other end of the spring 445 is abutted against the moving clamping part 444, the fixed clamping part 443 is fixedly connected with the fixing part 446, and the fixed clamping part 443 and the clamping rod 444 clamp the fabric on the mask facing side together. Pushing the push rod 441 causes the moving clamping portion 444 to move upwards, the gap between the moving clamping portion 444 and the fixed clamping portion 443 is enlarged, the push rod 441 is released after the fabric is pressed into the gap, the fabric is clamped, and the connection between the mask and the mask support is achieved.

The above description is based on specific embodiments, but the present application is not limited to these specific embodiments. That is, as long as the characteristics of the present invention are provided, the technique of appropriately changing these embodiments by those skilled in the art is also included in the scope of the present invention.
