[0002] The function of a breathing mask is to provide a space formed by a temporary enclosure, and by covering the patient's mouth or other areas and connecting to a designated air source, it provides auxiliary treatment or medical intervention for the patient and produces a protective effect. For example, in the prior art, there is a breathing mask and a ventilator with the announcement number CN113941067B, in which the breathing mask includes: a mask body, the edge of which is provided with a support component that fits the face; a first light source is arranged on the support component, and is used to perform photodisinfection on the inner wall of the mask body. The breathing mask provided in this application realizes photodisinfection of the inner wall of the mask body by installing a light source on the edge of the breathing mask, that is, installing a first light source on the support component that fits the face, thereby ensuring that the equipment is not contaminated when using the breathing mask for a long time and protecting the health of the user; Another example is a cushion for a breathing mask and a breathing mask with a publication number of CN106512174B in the prior art. The cushion includes: a connecting portion for connecting to a frame or a curved tube assembly of the breathing mask; a facial contact portion for contacting the patient's face, the facial contact portion being formed by a thin film; and a supporting portion connected between the connecting portion and the facial contact portion; wherein at least a portion of the facial contact portion has an outer extension extending from the supporting portion to the outside of the cushion and an inner extension extending from the outer peripheral side of the outer extension portion to the inside of the cushion. The cushion forms a reliable seal by forming two sealing areas through the facial contact portion, so that the same sealing effect can be achieved by applying a smaller supporting force, thereby improving the wearing comfort.

[0003] The above-mentioned existing technologies have made excellent improvements in improving the sealing and disinfection performance of the mask, and the practical effect is very good in practice. However, the simple inhaled air source is prone to poor intervention effect due to excessive dryness. In particular, elderly patients with respiratory diseases tend to breathe through their mouths and need to humidify sputum to prevent the formation of sputum scabs. When the patient's environmental medical conditions are limited and there is a lack of a complete respiratory intervention humidification system, the overall applicability of the mask is reduced.

When the patient's environmental medical conditions are limited, there is a lack of a complete respiratory intervention humidification system, which reduces the overall applicability of the mask.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a respiratory protective device with a humidification function, comprising a mask body and a strap for wearing the mask body, wherein the mask body covers the face and is connected to a medical air source through an air inlet pipe, the respiratory protective device also includes a humidifying tube for humidifying the inhaled air source, and the output end of the air inlet pipe is connected to the inside of the humidifying tube, and the output end of the humidifying tube is connected to the air inlet end of the breathing space covered by the mask body, and the inside of the humidifying tube humidifies the air source input through the air inlet pipe through a detachable and replaceable humidifying component.

[0006] Furthermore, the humidifying component includes a horizontal cylinder that is horizontally movable and inserted into the humidifying tube, and an adjustment plate with a breathing hole covering the inner end of the horizontal cylinder.

The traction rod is also movably installed in the breathing hole. The traction rod is also connected to a driving rod, which is driven to rotate via a horizontal axis installed in the horizontal cylinder.

[0008] As a further feature, the rotation operation end of the horizontal axis is the right end passing through the adjustment plate.

[0009] As a further feature, the rotation operation end of the horizontal axis is its left end, and the knob at the left end is also rotationally mounted on the left end of the horizontal cylinder and is located outside the cover body.

[0010] Furthermore, a slide groove is provided in the adjustment plate, and a slide rod is slidably connected in the arc-shaped slide groove, and the head end of the slide rod slides through the inside of the humidifying cotton and is fixedly connected to the traction rod, wherein the arc centers of the slide rod and the slide groove overlap with the axis of the horizontal axis.

[0011] As a further feature, a perforation is provided on the surface of the slide rod, and the perforation is connected to the infusion mechanism.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 9 , the present invention provides the following technical solutions: Embodiment 1: In this embodiment, in order to solve the technical problems existing in the prior art, the following solution is disclosed. Figure 1 and Figure 2, comprising a mask body 1 and a strap 2 for wearing the mask body 1, wherein the mask body 1 covers the face and is connected to a medical air source through an air inlet pipe 3, the respiratory protection device further comprises a humidifying tube 4 for humidifying the inhaled air source, and at the same time, the output end of the air inlet pipe 3 is connected to the inside of the humidifying tube 4, and the output end of the humidifying tube 4 is connected to the air inlet end of the breathing space covered by the mask body 1, and at the same time, the inside of the humidifying tube 4 humidifies the air source input through the air inlet pipe 3 through a detachable and replaceable humidifying component, the humidifying component comprises a horizontal cylinder 5 horizontally inserted into the inside of the humidifying tube 4 and an adjusting plate 6 with a breathing hole covered at the inner end of the horizontal cylinder 5, the adjusting plate 6 covers the through-type output end of the humidifying tube 4 after the horizontal cylinder 5 is fixed, and The humidification effect is changed by adjusting the breathing hole area through the adjustment mechanism, and the lower end of the horizontal cylinder 5 is also provided with a hole groove which is connected with the internal space of the humidification tube 4 after installation. The medical mask is fixed to the user's head and covers the mouth area through the strap 2. The air inlet pipe 3 is connected with oxygen or other gas sources. When inhaling, no components need to be installed inside the humidification tube 4. It is only necessary to seal the exposed outer end with a plug and directly serve as a gas flow-bearing component. The horizontal cylinder 5 can also be installed inside it, and the adjustment hole on the adjustment plate 6 can be adjusted before and after installation to change the contact effect between the humidification component and the airflow in the adjustment hole, thereby adjusting the humidification degree to meet the use requirements under more conditions.

[0019] In this embodiment, a specific adjustment method is further disclosed. Unlike the traditional method of replacing different humidifying components such as sponges with different water contents, in this embodiment, the water content of a given humidifying component or the contact area with the gas is changed by rotation and other operations to adjust the humidification effect. For details, please refer to Figure 2-Figure 4 In the scheme shown in , the adjustment mechanism includes a humidifying cotton 7 movably covered in the breathing hole and a traction rod 8 for squeezing or stretching the humidifying cotton 7. The traction rod 8 is also movably installed in the breathing hole, and the traction rod 8 is also connected to the driving rod 9. The driving rod 9 is driven to rotate via a horizontal axis 10 installed in the horizontal cylinder 5. The rotating operation end of the horizontal axis 10 is the right end passing through the adjustment plate 6. Before assembling the horizontal cylinder 5, the adjustment plate 6 containing the humidifying cotton 7 can be immersed in a humidifying solution, such as saline. When it is needed, the horizontal cylinder 5 is installed as a whole in the humidifying tube 4. Before installation or after it is pulled out after a period of use, the exposed horizontal axis 10 can be rotated and the traction rod 8 can be driven to rotate in the breathing hole through the driving rod 9, so that the humidifying cotton 7 is squeezed or stretched along an arc trajectory, and the corresponding contact area between the airflow and the humidifying cotton will be adjusted accordingly, thereby realizing the function of conveniently adjusting the humidification effect.

[0020] Embodiment 2: In this embodiment, another solution different from the above embodiment is disclosed. The difference between the solutions is mainly reflected in the different operation methods. Figure 5-Figure 6The cam 12 is provided with a sliding groove 12, and a sliding rod 11 is slidably connected in the sliding groove 12, and the head end of the sliding rod 11 slides through the interior of the humidifying cotton 7 and is fixedly connected to the traction rod 8, wherein the arc centers of the sliding rod 11 and the sliding groove 12 overlap with the axis of the horizontal axis 10. For the humidity adjustment of the above-mentioned embodiment, it is necessary to first remove the horizontal cylinder 5 from the humidifying tube 4 and then rotate the horizontal axis 10, while in the present embodiment, the horizontal axis 10 can be directly operated by the knob from the outside of the hood 1, which will not affect the patient during use, and the judgment of the humidification degree can be set with corresponding scales around the knob, which is more intuitive and convenient to use. At the same time, the sliding rod 11 can be flexibly slid in the sliding groove 12, which also increases the stability of the traction rod 8 during movement.

[0021] In this embodiment, a humidity adjustment scheme is further disclosed. The direction of improvement in this experiment is mainly to provide a solution for replenishing or extracting the humidifying liquid inside the humidifying cotton 7 after it is stretched or compressed. For details, refer to Figure 8-Figure 9 The surface of the slide bar 11 is provided with a perforation 13, which is connected to the infusion mechanism. The infusion mechanism can absorb or discharge the humidifying liquid when the perforation 13 squeezes or stretches the humidifying cotton through the rotation of the transverse axis 10. The infusion mechanism includes a cavity connected to the perforation 13 and opened in the slide bar 11, the traction rod 8 and the driving rod 9. The cavity is connected to the hollow structure in the transverse axis 10, and the hollow structure is connected to the infusion device through the connecting tube 14, which can connect the internal space of the transverse axis 10 with the external space. The infusion device is connected, and the infusion device can be a humidifying liquid containing mechanism with a water pump or a manual squeezing structure. When the horizontal axis 10 is in a rotating state, the stretched humidifying cotton 7 is replenished with water, and the humidifying liquid squeezed out of the squeezed humidifying cotton 7 can return to the humidifying liquid container from the perforation 13 and each cavity and the connecting tube 14, thereby ensuring that the humidifying liquid will not produce a large amount of change due to the change of the state of the humidifying cotton 7, ensuring the linearity of the humidification amount adjustment, and improving the humidification effect and the comfort of use of the breathing mask. .

[0022] Embodiment 3: At the same time, the following scheme is disclosed in this embodiment. This scheme is only disclosed as another means of containing and conveying humidifying liquid. Although it can produce a more convenient effect for driving the flow of liquid, it is more expensive, so it is not limited as the only scheme of this application. The infusion set includes a containing cylinder 15 fixed in the horizontal cylinder 5, and the containing cylinder 15 is movably penetrated by the horizontal axis 10, and a valve plate 16 is arranged in the containing cylinder 15, and the valve plate 16 is fixed on the horizontal rod 17. The outer surface of the horizontal rod 17 is horizontally slidably installed in the containing cylinder 15, and the inner surface is threadedly connected with the threaded section on the horizontal axis 10. When the horizontal axis 10 is in a rotating state, the cross rod 17 installed on its threaded section will drive the valve plate 16 to move inside the containing cylinder 15 due to the threaded transmission effect. During the movement, the pressure of the internal space of the containing cylinder 15 on the right side of the valve plate 16 will also change accordingly, thereby producing a corresponding fluid conveying effect.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
