MASK WEARING DEVICE

Technical Field

The utility model relates to the technical field of medical instruments, and

more particularly relates to a mask wearing device.

Background

The mask is a common article of daily use, and generally refers to a tool

which is worn on the mouth and nose for filtering the air entering the mouth and

nose to prevent harmful gases, odors and droplets from entering and leaving the

mouth and nose of a wearer. The mask is made of gauze or paper. The mask has a

certain filtering effect on the air that enters the lungs. Wearing the mask achieves a

good effect when respiratory infectious diseases are prevalent and when working in

polluted environments such as dust.

At present, many disposable masks are fixed on the head of the user through

the ear straps. The ear straps are generally designed as elastic tension straps,

thereby limiting the wearing range of the masks to a certain extent. For users with

different head sizes, the mask may be worn too loosely or too tightly.

Detailed Description

The technical solutions in the embodiments of the utility model will be clearly

and fully described below in combination with the drawings in the embodiments of

the utility model. Apparently, the described embodiments are merely part of the

embodiments of the utility model, not all of the embodiments. Based on the

embodiments in the utility model, all other embodiments obtained by those

ordinary skilled in the art without contributing creative labor will belong to the

protection scope of the utility model.

With reference to Fig. 1 to Fig. 4, a mask wearing device comprises an

endless belt 1, adjusting mechanisms 2 and clamping mechanisms 3. Each

adjusting mechanism 2 comprises a connecting piece 21 and a fixing piece 22. An

accommodating cavity with one open end is arranged inside the connecting piece

21. A first end of the endless belt 1 is slidably arranged in the accommodating

cavity. The fixing piece 22 is arranged on the connecting piece 21, and one end of

the fixing piece 22 extends into the accommodating cavity and can be abutted

against the first end of the endless belt 1 to fix the endless belt 1 into the accommodating cavity. The clamping mechanisms 3 are installed on the connecting pieces 21 for clamping the side edges of a mask. Two adjusting mechanisms 2 of the endless belt 1 are arranged, and respectively installed on the first end of the endless belt 1 and a second end of the endless belt 1. Two clamping mechanisms 2 corresponding to the adjusting mechanisms 3 are arranged.

Specifically, before use, the fixing pieces 22 of the adjusting mechanisms 2

and the endless belt 1 are in a first locked state, and both ends of the endless belt 1

extend into the accommodating cavity. During use, the user can firstly adjust the

endless belt 1 to a second state, i.e., the fixing pieces 22 of the adjusting

mechanisms 2 and the endless belt 1 are loosened. Then, both sides of the mask are

clamped by the clamping mechanisms 3, and next the connecting pieces 21

connected with both ends of the endless belt 1 are pulled, so as to adjust the length

of the endless belt 1 according to actual needs. Finally, the endless belt 1 is

adjusted to the first locked state with the fixing pieces 22 to meet the needs of

different users for the wearing tightness of the mask.

In conclusion, two same adjusting mechanisms 2 are designed on both ends of

the endless belt 1, and two same clamping mechanisms 3 are designed

correspondingly to the adjusting mechanisms 2 for clamping the mask. The

adjusting mechanisms 2 can lock and loosen the endless belt 1, so as to satisfy the

needs when adjusting the endless belt 1 and using the endless belt 1, thereby

achieving the needs of different users for the wearing tightness of the mask.

With reference to Fig. 3 to Fig. 4, in the utility model, each clamping

mechanism 3 comprises a rotating block 31 and a clamp 32; the rotating block 31

and the connecting piece 21 are hinged with a ball joint; and the clamp 32 is fixedly installed on the rotating block 31.

Specifically, in order to increase the comfort of the user in using the device,

that is, to make the rotating block 31 attach to the face of the user more closely, the

rotating block 31 and the connecting piece 21 are hinged with the ball joint and can

be rotated by 360 degrees, so as to facilitate the user in adjustment according to the

actual needs. In addition, the clamps 32 are fixedly installed on the rotating blocks

31 to keep the stability of clamping the mask.

With reference to Fig. 1 to Fig. 4, in the utility model, each connecting piece

21 is also provided with a through hole and a sliding groove; the fixing piece 22

comprises a poke rod 220, a top block 221 and a sliding block 222; the top block

221 is slidably installed in the through hole; the sliding block 222 is slidably

installed in the sliding groove; a first end of the poke rod 220 is hinged with the

sliding block 222; and a rod body of the poke rod 220 is hinged with the top block

221.

Specifically, when the endless belt 1 needs to be adjusted to the first state, the

poke rod 220 is moved, so that the top block 221 hinged with the poke rod 220

moves along the through hole and extends into the accommodating cavity to abut

against the endless belt 1. The sliding block 222 follows the movement of the top

block 221 and slides along the inner wall of the sliding groove to lock the endless

belt 1. When the endless belt 1 needs to be adjusted to the second state, the poke

rod 220 is moved, so that the top block 221 hinged with the poke rod 220 moves

out along the through hole to the outside of the accommodating cavity. The sliding

block 222 follows the movement of the top block 221 and slides along the inner

wall of the sliding groove to loosen the endless belt 1.

It should be noted that the poke rod 220 and the sliding block 222 are hinged

and the poke rod 220 and the top block 221 are hinged to ensure that the poke rod

220 may not collide with the sliding block 222 and the top block 221 during

movement to prevent the entire poke rod 220 from being stuck and unable to

move.

Further, considering that the poke rod 220 may not shake randomly when not

in use, as shown in Fig. 1, the utility model also comprises a locking piece 4, and

the poke rod 220 is fixed to the connecting piece 21 through the locking piece 4.

In particular, the locking piece 4 may be a spring, Velcro or buckle. The utility

model adopts the locking mode of magnetic attractable fixation. As shown in Fig. 1,

the locking piece 4 comprises a first magnetic attractable piece and a second

magnetic attractable piece 42 which can be attracted to each other; a groove is

formed in the connecting piece 21; the first magnetic attractable piece is installed

in the groove; and the second magnetic attractable piece 42 is installed on the

secondendofthepokerod220.

Specifically, after the endless belt 1 is adjusted, in order to fix the poke rod

220 to achieve the function of fixing the end of the endless belt 1, the first

magnetic attractable piece and the second magnetic attractable piece 42 that can be

attracted to each other are designed; and the first magnetic attractable piece and the

second magnetic attractable piece 42 are attracted in parallel, thereby achieving the

purpose of fixing the poke rod 220.

With reference to Fig. 4, in the utility model, the first end and the second end

of the endless belt 1 are respectively provided with a limiting block 10; an abutting

block is arranged at an opening of the accommodating cavity; and the limiting block 10 can be abutted against the abutting block to prevent the endless belt 1 from completely separating from the accommodating cavity.

With reference to Fig. 2, in the utility model, the endless belt 1 is made of soft

rubber material, and specifically PVC material which has good flexibility and can

adapt to fit the head of the user, so as to improve the comfort of the user.

It should be noted that the terms used herein are intended to merely describe

specific embodiments, not to limit the exemplary embodiments according to the

present application. As used herein, unless the context otherwise clearly indicates,

the singular form is also intended to include the plural form. In addition, it should

also be understood that when being used in the Description, the terms "comprise"

and/or "include" indicate the existence of features, steps, operations, devices,

components and/or combinations thereof.
