[0037] When using a ventilator to assist breathing for a child, place the breathing mask 1 at a suitable position on the patient's face, adjust and connect the head and neck elastic bands 11 to make them suitable for the patient, connect the oxygen inlet pipe 13 to the ventilator, and oxygen will pass through the oxygen inlet pipe 13 to the breathing mask 1 and be discharged through the one-way valve 14. When the child puts on the breathing mask 1, the first wiping piece 26 is located on the left and right sides of the child's chin. When asthma patients wear the breathing mask 1 for a long time, a large amount of secretions such as saliva will be produced. The first wiping piece 26 and the sponge block will collect the secretions. When a large amount of secretions are accumulated, the first wiping piece 26 needs to be replaced. When the first wiping piece 26 needs to be replaced, the family members grasp the sliding pieces 22 on both sides and move them outward. When the sliding piece 22 is separated from the bottom of the second sealing plate 23, the first telescopic spring 24, which was originally in a stretched state, drives the second sealing plate 23 to move obliquely downward until the second sealing plate completely separates the breathing mask 1 from the outside. The locking piece 27 is pulled by the hand to separate it from the card hole block. At this time, the reset spring 28 is stretched, and the family members manually open the first sealing plate 21, and then Continue to pull the sliding member 22 to drive the first wiping member 26 to move outward until the first wiping member 26 is pulled out, tear off the Velcro with secretions on the first wiping member 26, and replace it with a clean one. After the replacement is completed, first push the sliding member 22 inward to drive the first wiping member 26 to move inward. When the first wiping member 26 is about to approach the second sealing plate 23, the family member manually closes the first sealing plate 21 and re-engages it on the outside of the first fixing member 2, then releases the locking member 27, and the reset spring 28 contracts, so that the locking member 27 is embedded in the card hole block to lock the first sealing plate 21. When the sealing plate 21 moves upward, the first telescopic spring 24 is stretched, continuing to push the first wiping member 26 to move inward until the first wiping member 26 with the clean Velcro is re-located on the left and right sides of the patient's chin, and the replacement is completed.

[0038] Embodiment 2: Based on embodiment 1, Figure 8 and Fig. 9As shown, it also includes a liquid absorbent cloth 3, an extrusion member 31, a baffle cloth 32, a multi-section telescopic rod 33, a third telescopic spring 34 and a second fixing member 35. The second fixing member 35 is fixedly connected to the front lower part of the sliding member 22, the lower end of the multi-section telescopic rod 33 is fixedly connected to the second fixing member 35, the upper end of the multi-section telescopic rod 33 is fixedly connected to the extrusion member 31, the extrusion member 31 is extruded and matched with the breathing mask 1, the third telescopic spring 34 is wound on the multi-section telescopic rod 33, the upper end of the third telescopic spring 34 is connected to the extrusion member 31, and the third telescopic spring The lower ends of the plurality of fixing members 34 are connected to the second fixing member 35, the baffle cloth 32 wraps the multi-section telescopic rod 33 and the third telescopic spring 34 to protect the baffle cloth 32 and the multi-section telescopic rod 33 from being contaminated by saliva, the absorbent cloth 3 is located directly behind the breathing mask 1, the absorbent cloth 3 on the left is wound between the extrusion member 31 on the left and the second fixing member 35 on the left, the absorbent cloth 3 on the right is wound between the extrusion member 31 on the right and the second fixing member 35 on the right, the first fixing member 2 is extruded and matched with the extrusion member 31, and the absorbent cloth 3 and the baffle cloth 32 are stretched as the multi-section telescopic rod 33 is extended and retracted.

[0039] When the patient wears the breathing mask 1 for a long time, the absorbent cloth 3 is located in front of the patient's mouth and nose, and a large amount of saliva and other secretions will be left. Therefore, the absorbent cloth 3 needs to be replaced. The replacement of the absorbent cloth 3 and the replacement of the first wiping member 26 are carried out simultaneously. In the process of pulling out the sliding member 22, the sliding member 22 drives the second fixing member 35 to move outward first, and the extruding member 31 and the multi-section telescopic rod 33 also move outward at the same time. During the movement, the extruding member 31 contacts the breathing mask 1, and the breathing mask 1 moves the extruding member 31 downward, and the multi-section telescopic rod 33 contracts. Under the squeezing action of the extruding member 31, the naturally stretched third telescopic spring 34 begins to contract. At the same time, the absorbent cloth 3 and the barrier cloth also begin to curl from the stretched state, and then are pulled out together with the first wiping member 26. During the process of pulling out the member 22, the extrusion member 31 will take over the supporting effect of the sliding member 22 on the second sealing plate 23. After the second sealing plate 23 is separated from the extrusion member 31, the second sealing plate 23 will move to the side and downward and be inserted. After replacing the clean absorbent cloth 3, the patient's family members press the extrusion member 31 by hand, and the third telescopic spring 34 and the multi-section telescopic rod 33 shrink to make them lower than the height of the first fixed member 2. Then the sliding member 22 is pushed in. As the sliding member 22 is pushed in, the absorbent cloth 3 enters the breathing mask 1 from the first fixed member 2, and the third telescopic spring 34 in the contracted state stretches. The third telescopic spring 34 drives the multi-section telescopic rod 33 to stretch, and the originally curled partition cloth and absorbent cloth 3 stretch until the absorbent cloth 3 is fully unfolded and is in the middle position inside the breathing mask 1 again.

[0040] like Fig.10 and Fig.11As shown, it also includes an extrusion rod 4, a wedge block 41, a hose 42, a sealing box 43, a spray bottle 44 and a discharge pipe 45. One end of the extrusion rod 4 is fixedly connected to the locking piece 27, so that the extrusion rod 4 can move with the movement of the locking piece 27. The two spray bottles 44 are fixedly connected to the rear of the first fixing piece 2. The wedge block 41 is connected just above the spray bottle 44. The wedge block 41 and the extrusion rod 4 are squeezed and matched. The two sealing boxes 43 are connected to the first fixing piece 2. The sealing boxes 43 are both located on the inner side of the two spray bottles 44. The discharge pipes 45 are all placed inside the sealing boxes 43. One end of the hose 42 is connected to the spray bottle 44, and the other end of the hose 42 is connected to the discharge pipe 45. The hose 42 is used for mist delivery.

[0041] During the replacement in and out process of the first wiping member 26 and the absorbent cloth 3, they need to be disinfected. When it is necessary to clean the first wiping member 26 and the absorbent cloth 3 during the pulling out process, the propellant material mixture is first injected into the spray bottle 44. When the locking member 27 is pulled out, the squeezing rod 4 is driven to move in the pulling out direction of the locking member 27. The upper part of the squeezing rod 4 squeezes the wedge block 41, so that the liquid in the spray bottle 44 is converted into mist. The mist is transported to the discharge pipe 45 through the hose 42, and the first wiping member 26 and the absorbent cloth 3 passing through are sprayed and disinfected through the holes on the discharge pipe 45. During the pushing in process of the first wiping member 26 and the absorbent cloth 3, the locking member 27 is released, driving the squeezing rod 4 to move in the tightening direction of the return spring 28, the wedge block 41 is pressed, and the above process is repeated, thereby achieving the disinfection of the pushed in first wiping member 26 and the absorbent cloth 3.

[0042] like Fig.12 and Fig.13 As shown, it also includes a third fixing member 5, a second guide member 51, a wedge member 52 and a fourth telescopic spring 53. The third fixing members 5 are respectively fixed on the side of the sliding member 22 that is away from each other. The second guide members 51 are fixed to the outer side of the first sealing plate 21. The second guide member 51 and the third fixing member 5 are on the same horizontal line. One end of the wedge member is slidably connected to the second guide member 51, and the other end of the wedge member is pressed and fitted with the third fixing member 5. The fourth telescopic spring 53 is connected between the second guide member 51 and the wedge member 52.

[0043] When a child carries the breathing mask 1, the child's hand may accidentally touch the sliding member 22, which may cause the sliding member 22 to be pulled out, and the first wiping member 26 and the washing liquid cloth may be easily pulled out, which will affect the asthma treatment effect when the child uses it. Therefore, a third fixing member 5, a wedge-shaped member, a fourth telescopic spring 53, and a second guide member 51 are provided, and the third fixing member 5 is clamped by the wedge-shaped member, so that the sliding member 22 can be kept in a clamped state, and the child will not easily pull out the sliding member 22. If the sliding member 22 needs to be pulled out and replaced, the family member can forcefully pull the sliding member 22 outward, so that the sliding member 22 will drive the third fixing member 5 to move outward, and the third fixing member 5 will squeeze the wedge-shaped surface of the wedge-shaped member, so that the wedge moves forward and disengages from the third fixing member 5, and the fourth telescopic spring 53 is compressed. After the wedge and the third fixing member 5 are disengaged, the sliding member 22 can be easily pulled out, and when the third fixing member 5 and the wedge are separated, the fourth telescopic member will drive the wedge to move backward and reset.
