It includes respiratory medicine, gastroenterology, cardiology, neurology, oncology, endocrinology, hematology, infectious diseases, etc.

[0003] During internal medicine consultations, respiratory masks are commonly used by patients. Currently, the respiratory masks used during internal medicine consultations are often those mentioned in the patent publication number "CN217548738U". It uses activated carbon to adsorb dust to keep the air flow clean. Due to the long-term use of the respiratory mask, the activated carbon in the air flow channel is constantly eroded by unclean air flow and some dust in the air flow adheres to the activated carbon, reducing the adsorption function of the activated carbon. Moreover, activated carbon has its service life and needs to be replaced when necessary. Currently, the activated carbon is disassembled and replaced through a single splicing method.

Rubber bands for fixing the mask body to the patient's head are provided at both ends of the mask body. A positioning piece is provided below the through hole, and a through-channel is provided on the front surface of the positioning piece. An activated carbon layer for adsorbing dust in the air flow is inlaid on the inner surface of the channel in an interference fit manner. An air pipe for the patient to absorb O2 is provided below the activated carbon layer, and a split part is provided on the wall surface of the activated carbon layer.

[0008] Further, a valve is provided on the air pipe, and the air pipe is also connected to an O2 tank.

[0009] Further, the split part includes a fitting post provided on the wall surface of the activated carbon layer, and the fitting post is fixedly connected to the activated carbon layer. An open hole is provided at the tail of the fitting post.

[0010] Further, a hollow chamber is provided on one side of the fitting post. An opening is provided on the side wall of the hollow chamber, and a handle is provided in the opening. A lower cylinder with both ends through is provided on one side of the handle.

[0011] Further, a top cover is sleeved on the lower cylinder. The inner surface of the top cover is connected to one end of a disc spring, and the other end of the disc spring is provided with a cylinder with both ends through. The cylinder is located inside the lower cylinder, and a groove is provided on the side wall of the cylinder. A sphere made of brass is floating in the groove, and there are a pair of fitting posts.

[0012] Further, the wall surface of the fitting post has texture.

[0013] Further, the fitting post faces the open hole, and the open hole is located on the wall surface of the hollow chamber. One side of the handle protrudes from the side wall of the hollow chamber, and the lower cylinder is connected to the handle.

[0014] Further, the upper part of the cylinder is connected to the other end of the disc spring, and the cylinder and the disc spring form a reciprocating structure. The cylinder is frustum-shaped, the lower cylinder is frustum-shaped, the upper part of the top cover is fixedly connected to the hollow chamber, and the top cover is also frustum-shaped. The inner surface of the lower cylinder is in contact with the wall surface of the sphere, and the fitting post extends into the hollow chamber through the open hole on the wall surface, and the fitting post is in contact with the wall surface of the sphere.

[0015] Further, the width of the groove is greater than the diameter of the sphere.

[0016] Further, there are several spheres, and the distance between the centers of a pair of adjacent spheres is the same as the column diameter of the fitting post.

[0017] The beneficial effects of the present utility model are:

[0018] Through the interlocking column, handle, top cover, cylinder and ball, when the activated carbon layer is to be replaced and decomposed, the handle is moved backward through the opening in the side wall of the hollow chamber, so that the handle pulls the connected lower cylinder backward, and the lower cylinder pulls the connected cylinder backward, so that the cylinder moves backward in the top cover, and the cylinder pulls the disc spring to perform compression, so that the movement of the cylinder pulls the ball in the wall groove to rotate. Because the cylinder is frustum-shaped, several balls are allowed to run in the groove, and the distance between several balls is higher than the column diameter of the interlocking column, so that the ball does not touch the wall of the interlocking column, and the activated carbon layer is held to pull the interlocking column to move forward, so that the interlocking column is separated from the hollow chamber, so as to achieve efficient decomposition of the activated carbon layer, which is suitable for efficiently performing replacement operations on the activated carbon layer.

A pair of balls is provided in the groove of the side wall of the cylinder, and when the pair of balls is in front of the groove, the distance between the pair of balls is lower than the column diameter of the embedded column, so that the embedded column pulls the pair of balls in the groove of the cylinder to move backward, and the groove synchronously pulls the cylinder to move backward. Because the truncated cone structure of the lower cylinder allows the balls to move outward in the groove, the distance gap between the pair of balls is widened, and the embedded column penetrates through it, so that the activated carbon layer and the positioning piece can perform the assembly operation efficiently, and the operation is more convenient. Because there will be a bumping phenomenon when the mask is used, when the embedded column is pulled out in the reverse direction, the embedded column pulls the ball to move to one side, and the ball is synchronously affected by the inward force of the truncated cone-shaped lower cylinder. The further the ball moves forward, the narrower the gap is, and the more firmly the embedded column is clamped, thereby achieving a clamped state. Through the above operation, the efficient disassembly and replacement operation of several breathing masks is achieved, and the efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present utility model will be preferably described below in conjunction with the accompanying drawings and embodiments.

[0026] As Figures 1 to 6 shown, a breathing mask specially used for the internal medicine outpatient department of the present utility model includes:

[0027] A mask body 2, a through hole 3 inlaid with an acrylic sheet for viewing the outside is opened on the wall surface of the mask body 2, and rubber bands 4 for fixedly connecting the mask body 2 and the patient's brain are provided at both ends of the mask body 2. A positioning piece 6 for positioning is provided below the through hole 3, and a through-channel is provided on the front surface of the positioning piece 6 to communicate with the inside of the mask. An activated carbon layer 7 for adsorbing dust in the air flow is inlaid on the inner surface of the channel in a transition fit manner. An air delivery pipe 5 for the patient to absorb O2 is provided below the activated carbon layer 7, and a splitting and combining part 8 is provided on the wall surface of the activated carbon layer 7. After the patient wears the breathing mask specially used for the internal medicine outpatient department, when inhaling, the patient can inhale a mixed healthy air flow of O2 sent by the air delivery pipe 5 and clean air flow adsorbed by the activated carbon layer 7 and sent through the through-channel.

[0028] In a preferred but non-limiting embodiment of the present utility model, a valve is provided on the air delivery pipe 5, and the air delivery pipe 5 is also connected to an O2 tank. When the valve is opened, O2 in the O2 tank can send O2 to the air delivery pipe 5.

[0029] In a preferred but non-limiting embodiment of the present utility model, the splitting and combining part 8 includes a fitting post 82 provided on the wall surface of the activated carbon layer 7, and the fitting post 82 is fixedly connected to the activated carbon layer 7, and an open hole 86 is provided at the tail of the fitting post 82.

[0030] In a preferred but non-limiting embodiment of the present utility model, a hollow chamber 83 is provided on one side of the fitting post 82, an opening 85 is opened on the side wall of the hollow chamber 83, a handle 84 is provided in the opening 85, and a lower cylinder 89 with both ends penetrating is provided on one side of the handle 84.

[0031] In a preferred but non-limiting embodiment of the present utility model, a top cover 87 is covered on the lower cylinder 89, the inner surface of the top cover 87 is connected to one end of a disc spring 88, and the other end of the disc spring 88 is provided with a cylinder 90 with both ends penetrating. The cylinder 90 is located inside the lower cylinder 89, and a groove 822 is provided on the side wall of the cylinder 90, and a sphere 821 made of brass is floating in the groove 822. And there are a pair of fitting posts 82, and the pair of fitting posts 82 make the embedding of the activated carbon layer 7 more firm.

[0032] In a preferred but non-limiting embodiment of the present utility model, the wall surface of the fitting post 82 has texture.

[0033] In a preferred but non-limiting embodiment of the present utility model, the fitting post 82 faces the open hole 86, and the open hole 86 is located on the wall surface of the hollow chamber 83. One side of the handle 84 protrudes from the side wall of the hollow chamber 83. The lower cylinder 89 is connected to the handle 84, and the handle 84 drives the lower cylinder 89 to move. The handle 84 moves in the opening 85, which is conducive to disassembly.

[0034] In a preferred but non-limiting embodiment of the present utility model, the upper part of the cylinder 90 is connected to the other end of the disc spring 88, and the cylinder 90 and the disc spring 88 form a reciprocating structure. The cylinder 90 is frustum-shaped, the lower cylinder 89 is frustum-shaped, the upper part of the top cover 87 is fixedly connected to the hollow chamber 83, and the top cover 87 is also frustum-shaped. The lower cylinder 89 moves in the top cover 87. The inner surface of the lower cylinder 89 is in contact with the wall surface of the sphere 821. The fitting post 82 extends into the hollow chamber 83 through the open hole 86 on the wall surface. The fitting post 82 drives the sphere 821 to rotate downward in the groove 822, and the fitting post 82 is in contact with the wall surface of the sphere 821.

[0035] In a preferred but non-limiting embodiment of the present utility model, the width of the groove 822 is greater than the diameter of the sphere 821. The sphere 821 rotates downward in the groove 822.

[0036] In a preferred but non-limiting embodiment of the present utility model, there are several spheres 821. The distance between the centers of a pair of adjacent spheres 821 is the same as the diameter of the fitting post 82. The several spheres 821 rotate as the fitting post 82 moves. When the several spheres 821 move to the lowest part of the groove 822, their diameters are greater than the diameter of the fitting post 82, which is conducive to the separation of the fitting post 82.

[0037] During the internal medicine outpatient visit, it is fastened to the patient's head via the rubber bands 4 at both ends of the mask body 2. Then, the external scene is viewed through the acrylic sheet on the through hole. Next, the valve is opened, and the O2 in the O2 tank can send O2 to the air supply pipe 5. In this way, when the patient inhales, the patient can inhale the mixed healthy air flow of the O2 sent by the air supply pipe 5 and the clean air flow after the dust is adsorbed by the activated carbon layer 7 sent through the through-channel. The patient thus inhales the mixed healthy air flow, and then the dust in the air flow is adsorbed by the activated carbon layer 7 of the air flow channel. Moreover, the activated carbon layer 7 is connected via the positioning piece 6. When it is necessary to perform the replacement and decomposition operation on the activated carbon layer 7, it is moved backward through the opening 85 on the side wall of the hollow chamber 83 via the handle 84, so that the handle 84 pulls the connected lower cylinder 89 backward, and the lower cylinder 89 will pull the connected cylinder body 90 backward, so as to make the cylinder body 90 move backward in the top cover 87, and the cylinder body 90 pulls the disc spring 88 to be compressed. Thus, the movement of the cylinder body 90 pulls the ball 821 in the wall groove 822 to rotate. Because the cylinder body 90 is frustum-shaped, several balls 821 move in the groove 822. The distance between several balls 821 is greater than the column diameter of the fitting column 82, so that the balls 821 do not touch the wall surface of the fitting column 82. Hold the activated carbon layer 7 and pull the fitting column 82 forward to move, so that the fitting column 82 separates out of the hollow chamber 83, thereby achieving the efficient decomposition operation of the activated carbon layer 7, which is conducive to efficiently replacing the activated carbon layer 7. When it is necessary to perform the assembly operation on the new activated carbon layer 7, hold the new activated carbon layer 7 and pull the fitting column 82 to extend into the open hole 86. Because there are a pair of balls 821 provided in the side wall groove 822 of the cylinder body 90, and when the pair of balls 821 are at the front of the groove 822, the distance between the pair of balls 821 is less than the column diameter of the fitting column 82, so that the fitting column 82 pulls the pair of balls 821 in the groove 822 of the cylinder body 90 to move backward, and the groove 822 synchronously pulls the cylinder body 90 to move backward. Because of the frustum-shaped structure of the lower cylinder 89, the balls 821 move outward in the groove 822, making the distance gap between the pair of balls 821 wider. The fitting column 82 penetrates through this, so that the activated carbon layer 7 and the positioning piece 6 are efficiently assembled, and the operation is more convenient. Because when there is a collision phenomenon during the use of the mask, which causes the fitting column 82 to be pulled out reversely, the fitting column 82 pulls the ball 821 to move to one side, and the ball 821 is simultaneously affected by the inward action of the frustum-shaped lower cylinder 89. The narrower the gap during the forward movement of the ball 821, the tighter the fitting column 82 is clamped. Accordingly, the clamping state is achieved. Through the above operations, the efficient disassembly and replacement operations of several breathing masks are achieved, improving the efficiency.

[0038] The beneficial effects of the present utility model are as follows:

[0039] Via the fitting column, the handle, the top cover, the cylinder body and the sphere, when the replacement decomposition operation is to be performed on the activated carbon layer, run backward through the opening in the side wall of the hollow chamber via the handle, so that the handle pulls the connected lower cylinder backward, and the lower cylinder pulls the connected cylinder body backward, so that the cylinder body runs backward in the top cover, and the cylinder body pulls the disc spring to perform compression, so that the movement of the cylinder body drives the sphere in the wall groove to rotate. Since the cylinder body is frustum-shaped, several spheres run in the groove, and the distance between several spheres is greater than the column diameter of the fitting column, so that the spheres do not touch the wall surface of the fitting column. Hold the activated carbon layer and pull the fitting column forward, so that the fitting column separates out of the hollow chamber, thereby achieving the efficient decomposition operation of the activated carbon layer, which is suitable for efficiently performing the replacement operation of the activated carbon layer. When the new activated carbon layer is to be assembled, hold the new activated carbon layer and pull the fitting column into it through the open hole. Since a pair of spheres are provided in the side wall groove of the cylinder body, and when the pair of spheres are at the front of the groove, the distance between the pair of spheres is less than the column diameter of the fitting column, so that the fitting column drives a pair of spheres in the groove of the cylinder body backward, and the groove synchronously drives the cylinder body backward. Since the frustum-shaped structure of the lower cylinder allows the spheres to run outward in the groove, the distance gap between the pair of spheres becomes wider, and the fitting column penetrates through this, so that the activated carbon layer and the positioning piece are efficiently assembled, and the operation is more convenient. Since there will be a knocking phenomenon during the use of the mask, when the fitting column is pulled out reversely, the fitting column drives the sphere to run to one side, and the sphere is simultaneously affected by the inward action of the frustum-shaped lower cylinder. The narrower the gap during the forward movement of the sphere, the tighter the fitting column is clamped, thus achieving a clamped state. Through the above operations, the efficient decomposition and replacement operation of several breathing masks are achieved, improving the efficiency.

[0040] The above describes the present invention in the form of examples. Those skilled in the art should understand that the present disclosure is not limited to the above-described embodiments, and various changes, alterations and substitutions can be made without departing from the scope of the present invention.
