[0028] like Figure 1 and 2 As shown, a toy smoke bomb comprises a shell, a gas cylinder and smoke powder.

[0029] The outer shell includes an elastic body 7, a buffer sleeve 15, a powder bin body 1, a bottom cover 10 and a packaging film 8. The elastic body 7 is a cylindrical member with openings at the upper and lower ends. The elastic body 7 has a certain hardness and weight, and the outer diameter of the elastic body 7 meets the need of being held by one hand. The buffer sleeve 15 is a cylindrical member with openings at the upper and lower ends. The buffer sleeve 15 has shock-absorbing properties or vibration-absorbing properties and can be made of sponge or polyethylene foam plastic. The outer diameter of the buffer sleeve 15 is equal to or slightly larger than the inner diameter of the elastic body 7. The buffer sleeve 15 is sleeved in the elastic body 7. The length of the buffer sleeve 15 can be less than the length of the elastic body 7, but the buffer sleeve 15 is at least installed at the position of fixing the gas cylinder and the powder bin body 1, and the buffer sleeve 15 can absorb vibration. The powder bin body 1 is provided with a powder bin, and the lower end of the powder bin body 1 is provided with an opening connected to the powder bin. The side of the powder bin body 1 is provided with a circular powder spraying port 18 with a diameter of about 20 mm connected to the powder bin. There are two powder spraying ports 18, which are symmetrically arranged. The opening of the powder bin body 1 is arranged downward, and the lower end of the powder bin body 1 is sleeved in the buffer sleeve 15. The outer diameter of the lower end of the powder bin body 1 is equal to or slightly larger than the inner diameter of the buffer sleeve 15. The bottom cover 10 is short cylindrical, and the bottom cover 10 is detachably fixed to the lower end opening of the elastic body 7. The bottom cover 10 has a certain weight. The packaging film 8 is wrapped around the outer side of the assembled elastic body 7 and the powder bin body 1 to fix the elastic body 7 and the powder bin body 1. The packaging film 8 can be made of a polyethylene plastic film with good toughness. The packaging film 8 can cover the powder spraying port 18 or not.

[0030] The gas cylinder can be opened electrically, and the gas cylinder is filled with compressed gas of about 20 atmospheres. The gas cylinder is detachably arranged in the shell, and the mouth of the gas cylinder faces the end of the shell provided with the powder spraying port 18. Specifically, the mouth of the gas cylinder faces the powder bin, and the mouth of the gas cylinder is generally arranged in the powder bin. The lower part of the bottle body 6 of the gas cylinder is sleeved with the buffer sleeve 15, and the outer diameter of the lower part of the bottle body 6 is equal to or slightly larger than the inner diameter of the buffer sleeve 15. The upper part of the bottle body 6 of the gas cylinder is sleeved with the powder bin body 1, and the outer diameter of the upper part of the bottle body 6 is equal to or slightly smaller than the inner diameter of the lower end opening of the powder bin body 1. A buckle limit is provided at the connection between the upper part of the bottle body 6 and the lower end opening of the powder bin body 1, for example, a card slot is provided on the upper part of the bottle body 6, and a convex point or convex ring used in conjunction with the card slot is provided on the inner side of the lower end opening of the powder bin body 1. More specifically, the gas cylinder includes a bottle body 6, a rubber plug 5 and a flip-top bottle cap 17. The bottle body 6 is a steel cylinder. The rubber plug 5 is sealed and filled in the bottle mouth. One end of the bottle cap 17 is axially connected and fixed to the bottle mouth of the bottle body 6 through a cover pin 16. The axial direction of the cover pin 16 is parallel to the axial direction of the powder spraying port 18 to avoid blocking the powder spraying port 18 when the bottle cap 17 is opened. The other end of the bottle cap 17 is tied to the bottle mouth through a sealing rope 4. In view of the problem that the combustion of chemical agents will produce high temperature, chemical smoke, easily cause fires and seriously pollute the environment, and the smoke also greatly affects the health of the body and affects the user experience, the power source is directly replaced, and the compressed gas filled in the gas cylinder is used as the power, which does not produce high temperature and other products. At the same time, the gas cylinder also has a certain weight, which can improve the grip and enhance the user experience. According to the test, the compressed air will not cause harm to the human body during the release process, and it can be released by holding it with one hand.

[0031] The smoke powder is filled in a plastic bag, which is a rectangular bag with a length of about 50 mm and a width of about 30 mm. The length direction of the plastic bag is parallel to the axial direction of the powder spraying port 18. The plastic bag containing the smoke powder is located in the powder bin, and the plastic bag is located between the gas cylinder and the powder spraying port 18. The smoke powder is made of corn starch. In order to solve the problem that the burning of chemical reagents produces irritating odors that are harmful to the human body and pollute the environment, corn starch is used as smoke, which is harmless to the human body and can be naturally degraded, which is more in line with the background of the country's advocacy of environmental protection.

[0032] The toy smoke bomb also includes a heating wire 25, a battery 11, a switch 9, a circuit board 14 and a buzzer 13. The battery 11, the switch 9, the circuit board 14 and the buzzer 13 are all fixed to the bottom cover 10. The battery 11 is a rechargeable battery 11. The charging port 22 of the battery 11 is arranged on the bottom side of the bottom cover 10. The charging port 22 and the battery 11 are electrically connected through the charger 12. The button 21 of the switch 9 is arranged on the bottom side of the bottom cover 10. The heating wire 25 is arranged at the sealing rope 4 and is attached to the sealing rope 4. The battery 11 is electrically connected to the circuit board 14 through the switch 9. The circuit board 14 is electrically connected to the buzzer 13. The circuit board 14 is electrically connected to the heating wire 25 through a joint, so that the circuits of the heating wire 25 and the circuit board 14 can be conveniently connected when the gas cylinder is replaced. The heating wire 25 and the sealing rope 4 can be screwed into one body, and when the gas cylinder is replaced, they are replaced together. The circuit board 14 is used to control the electric heating wire 25 to burn off the sealing rope 4 around the bottle mouth, and the compressed gas pops open the rubber plug 5 and the bottle cap 17 to open the bottle mouth. The compressed gas is released to spray out the smoke without generating high temperature.

[0033] After the electric heating wire 25 is energized, the sealing rope 4 will be burned off. Under the action of the compressed gas, the bottle cap 17 will rotate around the cap pin 16, the rubber plug 5 will be ejected, and the bottle mouth will be opened; at the same time, when the bottle cap 17 is opened at a high speed, the plastic bag containing the smoke powder will be lifted up and smashed, so that the smoke powder fills the powder bin; then the compressed gas is quickly released from the gas cylinder and breaks through the protective film along the powder spraying port 18 (the protective film can be a packaging film 8; when there is no packaging film 8, a protective film can be separately provided at the powder spraying port 18), and the smoke powder is blown into the air. According to measurement, under windless conditions, a smoke area with a diameter of 80 cm and a height of about 2 meters can be formed. Under light wind conditions, a smoke area with a diameter of about 1 meter will be formed, and the smoke lasts for about 5 seconds. By using gas cylinders filled with compressed gas to form extremely rapid airflow, instead of the existing chemical reagent combustion gas production to form extremely rapid airflow, no additional fire source is needed for ignition, and it is easy to use; it will not burn to produce high temperature and irritating gases, and there is no danger or pollution; after each bombing, the gas cylinder and smoke powder can be replaced so that its parts except the gas cylinder and smoke powder can be recycled, thereby improving utilization and avoiding waste of resources.

[0034] When designing the layout of the battery 11, switch 9, circuit board 14 and buzzer 13 on the bottom cover 10, an eccentric structure is formed as a whole to ensure that one of the two powder spraying ports 18 can face upward (at this time, the toy smoke bomb has been thrown out and is in a lying state).

[0035] The toy smoke bomb also has a decorative pin 20, a pull ring 19 and a pin cap 2. The decorative pin 20 is inserted through the powder bin body 1, and both ends of the decorative pin 20 are located outside the powder bin body 1. The pull ring 19 is connected to one end of the decorative pin 20, and the pin cap 2 is sleeved on the other end of the decorative pin 20. By providing the decorative pin 20, the pull ring 19 and the pin cap 2, the aesthetics is improved, and a function similar to the pin pulling and use of a real smoke bomb is achieved.

[0036] The toy smoke bomb also includes a movable powder blocking sheet 3, which is located between the bottle mouth of the gas cylinder and the smoke powder, so as to prevent the smoke powder from falling into the annular space around the bottle mouth. Once the smoke powder falls into this area, it is difficult to spray out and utilize it.

[0037] The circuit is designed as a time-delay circuit. After the switch 9 is pressed, the buzzer 13 starts to work and emits a beep. After that, the working time interval gradually shortens, and the sound is similar to beep-beep-beep-beep-beep-beep-beep, which becomes more and more rapid. Then, the heating wire 25 is energized to burn the sealing rope 4. During this process, if the switch 9 is stopped, the circuit will stop working. After the button 21 is pressed again, it will work again. Specifically, as Figure 3 The circuit board 14 shown in the figure starts to be powered on, and the program directly enters the interrupt service function. The timer starts working, and the active buzzer 13 pin is powered on once every second. The buzzer 13 rings continuously for 3 seconds, and then the program exits the interrupt and enters the main function. Use the delay function to intermittently power on and off the buzzer 13 pin, and the power-off interval time becomes shorter and shorter. The buzzer 13 starts to ring faster, and the total acceleration time is 2 seconds. Then the single-chip computer 23 gives the control MOS field effect tube 24 pin a high level, and the field effect tube 24 starts to work, so that the control heating wire 25 starts to work, burns the sealing rope 4, and the high-pressure gas inside the gas cylinder is discharged. After the heating wire 25 is powered on for 3 seconds, the program is powered off.

[0038] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
