[0024] Example:

[0025] See also Figure 1The embodiment of the utility model provides a protective mask, including a mask body 1, a strap and a connector 2. The two ends of the mask body 1 are connected, one end of the mask body 1 is the wearing side and the cross section is triangular, which is conducive to fitting with the face; a fixing seat 11 is provided on the outside of the mask body 1, and at least two fixing seats 11 and connectors 2 are provided, and the fixing seats 11 and connectors 2 are connected one by one, and the strap is connected to all connectors 2. For example, the connector 2 and the fixing seat 11 are respectively provided with two, the two fixing seats 11 are distributed on the opposite sides of the mask body 1, the two connectors 2 are respectively connected to the two fixing seats 11, and the two ends of the strap are respectively connected to the two connectors 2, so that the protective mask can be fixed on the user through the strap. According to actual needs, three, four, etc. connectors 2 can be provided, wherein three connectors 2 are connected into a triangle shape, and four connectors 2 are connected into a rectangle.

[0026] See also Figure 1 and Figure 2 The connector 2 includes a first connector 21 and a second connector 22 fixed to the first connector 21. The first connector 21 is installed in the installation cavity 111, and the second connector 22 is at least partially arranged on the outside of the fixing seat 11 and connected to the strap. Since the first connector 21 is installed in the installation cavity 111, the connector 2 is assembled with the fixing seat 11, and the fixing seat 11 is fixed on the cover body 1, and the strap is connected to the second connector 22, so that the strap is connected to the cover body 1 through the connector 2 and the fixing seat 11, and the connection of the strap to the cover body 1 does not require the provision of a magnetic attraction structure, and will not affect patients with pacemakers installed, thereby expanding the use range of the protective mask. Moreover, the connector 2 has a simple structure and low manufacturing cost.

[0027] It should be noted that the fixing seat 11 and the cover body 1 are connected as one body, that is, the fixing seat 11 and the cover body 1 can be formed as one piece; the first connecting part 21 is inserted into the installation cavity 111 along the length direction of the installation cavity 111, and the strap is directly installed on the second connecting part 22, so that the assembly method of the protective mask is relatively simple.

[0028] See also Figure 1 and Figure 2The first connection part 21 is adapted to the installation cavity 111, and the first connection part 21 and the installation cavity 111 are interference fit to ensure that the first connection part 21 is not easy to be separated from the fixing seat 11. The fixing seat 11 is provided with a step 112 at one end of the opening of the installation cavity 111. One end of the first connection part 21 abuts against the step 112, and the other end abuts against the bottom wall of the installation cavity 111. The step 112 and the bottom wall of the installation cavity 111 together restrict the first connection part 21 in the installation cavity 111. Specifically, the cross-sectional shape of the step 112 is set to be the same as the cross-sectional shape of the mounting cavity 111, and the outer dimensions of the first connecting portion 21 are larger than the inner diameter dimension of the location where the step 112 is provided in the mounting cavity 111, that is, the step 112 is provided to be raised relative to the inner circumferential wall of the fixing seat 11, so that the step 112 can prevent the first connecting portion 21 from moving along the axial direction of the fixing seat 11 toward the direction away from the bottom wall of the mounting cavity 111, and the bottom wall of the mounting cavity 111 can prevent the first connecting portion 21 from moving along the axial direction of the fixing seat 11 toward the direction away from the step 112, thereby restricting the first connecting portion 21 in the mounting cavity 111.

[0029] See also Figure 1 and Figure 3 The first connection part 21 is columnar, and a first notch 211 is provided on the outer side of the first connection part 21. The first notch 211 extends a predetermined distance along the radial direction of the first connection part 21, and both ends of the first notch 211 extend to both ends of the first connection part 21, so that the first connection part 21 can shrink or expand in the radial direction. Specifically, the first notch 211 provided on the first connection part 21 must ensure that the first connection part 21 is elastic and can shrink or expand in the radial direction, and must also ensure that the first connection part 21 has sufficient strength to be installed in the installation cavity 111, that is, the first notch 211 cannot be too large or too small. During the process of installing the first connecting part 21 into the mounting cavity 111, force is first applied to the first connecting part 21 to make the first connecting part 21 contract radially and be in an elastic compression state. At this time, the outer diameter of the first connecting part 21 becomes smaller, which facilitates the installation of the first connecting part 21 into the mounting cavity 111; after the first connecting part 21 is installed into the mounting cavity 111, the first connecting part 21 is in an elastic recovery state, the first connecting part 21 expands radially, the outer diameter of the first connecting part 21 becomes larger, and the first connecting part 21 abuts against the inner circumferential wall of the fixing seat 11, thereby realizing an interference fit between the first connecting part 21 and the mounting cavity 111.

[0030] See also Figure 3 The two ends of the first connection part 21 are connected to form an inner cavity 212, and the first notch 211 is connected to the inner cavity 212 of the first connection part 21, so that the first connection part 21 can be regarded as formed by winding a plate, which is conducive to achieving elasticity of the first connection part 21. The first notch 211 and the second connection part 22 are distributed on opposite sides of the first connection part 21, which is conducive to applying force to the first connection part 21 to make it elastically deformed.

[0031] See also Figure 1 and Figure 2 In some embodiments, the outer side of the fixing seat 11 is provided with a second notch 113 connected to the installation cavity 111, one end of the second connection part 22 is fixed to the peripheral side of the first connection part 21, and the other end passes through the second notch 113 and extends to the outer side of the fixing seat 11, that is, the first connection part 21 is installed in the installation cavity 111, and the strap is connected to the part of the second connection part 22 extending to the outer side of the fixing seat 11, so as to realize the connection between the strap and the mask body 1. Moreover, the opening width of the second notch 113 is greater than the thickness of the second connection part 22, and the first connection part 21 is coaxially arranged with the fixing seat 11, so that after the second connection part 22 is subjected to force, it can drive the first connection part 21 to rotate relative to the fixing seat 11, thereby improving the use flexibility of the protective mask. In other embodiments, one end of the second connection part 22 is fixed to one end face of the first connection part 21, and the other end extends to the outer side of the fixing seat 11; wherein, the second connection part 22 can be in a "7-shaped" shape.

[0032] It should be understood that since the first connecting portion 21 can rotate relative to the fixing seat 11, when the strap is connected to the second connecting portion 22, the second connecting portion 22 can be moved away from the cover body 1 by rotating the first connecting portion 21, so that the cover body 1 will not hinder the installation of the strap, thereby facilitating the connection between the strap and the second connecting portion 22; and, when the strap is fixed on the user, the angle of the strap can also be adjusted to facilitate tying or buckling the straps together.

[0033] See also Figure 1 and Figure 2 A mounting hole 221 is provided at one end of the second connection portion 22 away from the first connection portion 21 , and the strap is connected to the second connection portion 22 through the mounting hole 221 . For example, the strap is tied to the first connection portion 21 through the mounting hole 221 .

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
