The specific embodiment

Referring to Fig. 1 and Fig. 2, the air pressing type firecrackers of the utility model, it comprises several quick-fried loud unit 1 and the some tracheaes 2 that are used to connect each quick-fried loud unit; Also comprise aerating device 3; Each quick-fried loud unit 1 comprises shell 4, be positioned at shell and become the inner casing 5 of sealing shape and be positioned at shell and the gas that is connected with inner casing divides part, and gas divides part to comprise that an air admission hole 6, first passage 7, second passage 8, the 3rd passage 9, four-way pore 10, five-way pore 11, the 6th passage 12, the 7th passage 13 and a venthole 14, the five-way pores 11 are connected with a check valve 15; Gas divides and is provided with the piston 16 that can in gas divides part, slide in the part; Piston 16 is provided with first cannelure 17 and second cannelure 18, and air admission hole 6 communicates with aerating device 3, and first passage 7 can communicate with second passage 8 through first cannelure 17; The 3rd passage 9 can communicate with four-way pore 10 through second cannelure 18; Check valve 15 communicates with inner casing 5, is provided with a diaphragm seal 19 between the 6th passage 12 and the inner casing 5, if be equipped with an inner cap 20 on the inner casing 5; Diaphragm seal then is located on the inner cap 20; Shell 4 is provided with a passage 21, is coated with one deck paper 22, the seven passages 13 on the outer peripheral face of shell 4 and communicates with passage 21 on the shell 4.

Referring to Fig. 1 and Fig. 2, during use, get into the air admission hole 6 of first quick-fried loud unit through tracheae with 3 pairs of gas pressurized of aerating device and with pressed gas; At this moment, first passage 7, second passage 8 are by the piston blocking-up, and this gas circuit is obstructed; And the 3rd passage 9 communicates through second cannelure 18 on the piston 16 with four-way pore 10, and pressed gas gets into five-way pore 11 then through four-way pore 10, and is pressed in the inner casing 5 through check valve 15; Gas in the inner casing 5 constantly increases fast, and pressure also constantly increases fast, when gas pressure increases to a certain degree; Diaphragm seal 19 is broken through; Explosive sound is produced and sent to pressed gas moment in the inner casing 5 at a high speed, realizes the explosive sound of firecrackers, through the 6th passage 12 piston is pushed to the other end after pressed gas is gone out in the inner casing 5; The pressed gas of going out is discharged through the passage on the 7th passage 13 and the shell 4 21 and one deck paper 22 that coats on shell 4 outer peripheral faces is broken through and splits and scatter, and realizes another feature of firecrackers; When piston is pushed to the other end; First passage 7 communicates through first cannelure 17 with second passage 8; And the 3rd, four-way pore 9,10 blocked by piston, the new pressed gas that aerating device 3 is compressed into is through first, second passage 7,8, and gets into the second quick-fried loud unit through venthole 14 and tracheae 2; The second quick-fried loud unit repeats the process of the first quick-fried loud unit; By that analogy, several quick-fried loud unit that link together through tracheae are the quick-fried sound of order one by one, until last the quick-fried sound in quick-fried loud unit.After the use,, reusable at simple and convenient replacing diaphragm seal and paper and after restoring piston.

The air pressing type firecrackers of the utility model, it comprises several quick-fried loud unit, some tracheae and the aerating devices that are used to connect each quick-fried loud unit, the gas that described quick-fried loud unit comprises shell, is positioned at the inner casing of shell and one-tenth sealing shape and is positioned at shell and is connected with inner casing divides part; Be coated with one deck paper on the outer peripheral face of shell, through aerating device gas be pressed into gas and divide part, divide part that gas is pressed into inner casing through gas then; Gas pressure in inner casing is to decode mounting and send quick-fried sound of backlash to a certain degree; Gas gets into gas once more and divides part, and divides the passage on the part to compress into the passage of shell and break through one deck paper that coats on the shell outer peripheral face through gas, produces firecracker effect; Adopt the firecrackers of this kind structure; Simulate effect is good, and cost is low, and is simple in structure and easy to use.

The above is merely the preferred embodiment of the utility model; And not only above restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included in the protection domain of the utility model.
