The method for quickly replacing the medicine tank comprises the following steps: when changing removable medicinal cupping in the use, should ensure to insert a removable medicinal cupping all the time in the self-rescuer to ensure that respirator part, breathing cycle part and removable medicinal cupping part can constitute one set of mixed closed structure jointly, make the user can continue to breathe. When only inserting a removable medicinal cupping in the self-rescuer, should open another reserve removable medicinal cupping at first and insert for insert two removable medicinal cupping in this self-rescuer, later the user can take out another removable medicinal cupping that needs to be changed. When two replaceable medicine cans are inserted, only one medicine can needs to be replaced, and the medicine can be directly taken out for replacement. When two replaceable canisters are inserted, the user must first replace one of the replaceable canisters and then replace the other replaceable canister after the replacement is complete.
The state of the control buckle 33 can be changed by pressing the control rod 31 and the medicine pot shell 25. After the medicine can shell 25 is pressed down, the part of the control buckle 33 in the direction of the control inner clamping head 33.1 is pressed down, at the moment, the control buckle 33 is fixed in a pressed-down state through the mutual matching of the control inner clamping head 33.1 and the control buckle limiting part 4.2 on the lower shell 4, and the control upper clamping head 33.2 above the control buckle 33 is also pressed down to fix the position of the medicine can shell 25. After the control rod 31 is pressed down, the outer clamping head 33.3 part of the control buckle 33 in the opposite direction of the inner clamping head 33.1 is pressed down, at the moment, the control buckle 33 is fixed in a bouncing state through the mutual matching of the control inner clamping head 33.1 and the control buckle limiting part 4.2 on the lower shell 4, the control upper clamping head 33.2 is also bounced, the fixed constraint on the medicine can shell 25 is released, and the control buckle 33 pushes the medicine can shell 25 upwards.
Fig. 1, 3 and 9 further illustrate the mating relationship between the resilient catch 31.1 on the control lever 31, the canister receiving housing door 7 and the plunger catch hole 6.2 on the canister receiving housing 6. In the state shown in the figure, the elastic buckle 31.1 partially penetrates through the press rod clamping hole 6.2 to abut against the lower part of the medicine pot accommodating shell door 7, so that the medicine pot accommodating shell door 7 cannot be rotated to be opened, at the moment, the medicine pot accommodating shell door 7 and the medicine pot accommodating shell door rubber gasket 9 are mutually matched to form a closed state, the replaceable medicine pot cannot be inserted, and dust and toxic gas in the external environment can be prevented from entering. If the medicine can receiving shell door 7 is opened in a rotating mode, the control rod button 31.3 is pressed downwards to enable the control rod 31 to move downwards, the elastic buckle 31.1 is connected with the control rod to move downwards, the elastic buckle 31.1 is separated from the press rod clamping hole 6.2 at the moment, the medicine can receiving shell door 7 can be opened, and a replaceable medicine can be inserted.
The preferred embodiment is shown in fig. 2 and 4 for the internal assembly after hiding the top cover 1, the upper shell 2 and the mask portion. Wherein the air inlet protective shell 17 and the air outlet air bag protective shell 24 are arranged in parallel and inserted into the middle shell guide rail 3.3.
When arranging this self-rescuer, user self should be equipped with one and sealed be equipped with two chemical oxygen self-rescuer of changing the medicinal cupping, simultaneously in working space, open up a plurality of spaces and be used for depositing sealed removable medicinal cupping, be convenient for in time look for removable medicinal cupping in the working face in the user after the emergence accident.
The above description is only exemplary of the present invention and should not be taken as limiting the invention, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
