[0027] Embodiment 1: Figure 1As shown, an electron emission device includes a gas storage member 1, and a gas outlet 101 is arranged on the top of the gas storage member 1. For reference, the gas storage member 1 can be a gas storage bottle or a gas storage tank, and a pressing member 2 is arranged on the gas outlet 101, and the pressing member 2 is used to seal the gas outlet 101; the rotating end of the pressing member 2 is hinged to the gas outlet 101, and the free end of the pressing member 2 is connected to the gas outlet 101 through a connecting member 3, and an electronic heating component 4 is arranged on one side of the connecting member 3, and the electronic heating component 4 is used to fuse the connecting member 3; the electronic heating component 4 includes an electric heating wire 401, a switch 402 and a power supply 403, one end of the electric heating wire 401 is connected to the connecting member 3, and the electric heating wire 401 is used to fuse the connecting member 3, and the other end of the electric heating wire 401 is connected to the switch 402, and the switch 402 is connected to the power supply 403.

[0028] It should be noted that the heating wire 401 includes a heating wire and an electric wire. When connecting, the electric wire is connected to the heating wire. This can be done using a wire terminal. The wire terminal is pressed tightly and the anti-loosening screw is tightened. The wire is firmly connected to the heating wire. To ensure safety, the wire terminal is wrapped in insulating tape.

[0029] For reference, the connecting member 3 is made of a burnable material, such as a binding rope woven from hay or cotton and linen.

[0030] In this embodiment, the gas storage member 1 has been pre-filled with gas (such as compressed air or other compressed gas) at a certain pressure. The air outlet 101 is tightly sealed by the pressing member 2 to ensure that the gas will not leak. The rotating end of the pressing member 2 is hinged to the air outlet 101 so that it can rotate around the hinge point, and the free end of the pressing member 2 is connected to the air outlet 101 through a connecting member 3 (such as a binding rope woven from hay or cotton and linen). The electronic heating component 4 is composed of an electric heating wire 401, a switch 402 and a power supply 403. One end of the electric heating wire 401 is in contact with the connecting member 3, and the other end is connected to the switch 402 through an electric wire, and the switch 402 is connected to the power supply 403. The heating wire in the electric heating wire 401 is a heating element that generates heat when current passes through it.

[0031] When it is necessary to spray gas, the operator presses the switch 402. The power supply 403 then provides electrical energy to the electric heating wire 401, and the electric heating wire begins to heat up. Since the connecting member 3 is made of a burnable material (such as a binding rope woven from hay or cotton and linen), the connecting member 3 is gradually melted under the high temperature of the electric heating wire. As the connecting member 3 is melted, the free end of the pressing member 2 loses connection, and the pressing member 2 opens rapidly under the action of the gas pressure, thereby releasing the gas in the gas storage member 1. The gas is ejected through the gas outlet 101 to achieve the spraying effect.

[0032] Embodiment 2: In a possible implementation mode, Figure 2 As shown, a first protruding piece 1011 is provided on the outer wall of the air outlet 101, a second protruding piece 201 is provided on the free end of the pressing piece 2, one end of the connecting piece 3 is connected to the first protruding piece 1011, and the other end of the connecting piece 3 is connected to the second protruding piece 201. The first protruding piece 1011 can be a metal block or a metal ring directly welded on the outer wall of the air outlet 101, and the second protruding piece 201 can be a metal block or a metal ring directly welded on the free end of the pressing piece 2. If the connecting piece 3 is a thin rope (such as a cotton and linen woven binding rope), it can directly pass through the metal ring of the first protruding piece 1011 and the metal ring of the second protruding piece 201, and then be fixed at the end.

[0033] Embodiment 3: In a possible implementation manner, as Figure 3 As shown, the connecting member 3 includes a first connecting part 301, a fuse part 302 and a second connecting part 303. The first connecting part 301 is connected to the first protrusion 1011, and the second connecting part 303 is connected to the second protrusion 201. The fuse part 302 is respectively connected to the first connecting part 301 and the second connecting part 303. For reference, an adhesive can be used to connect the fuse part 302 to the first connecting part 301 and the second connecting part 303.

[0034] One end of the electric heating wire 401 is connected to the fuse part 302. The fuse part 302 is made of a burnable material, such as plastic, nylon or other heat-sensitive materials, to ensure that the electric heating wire 401 can be quickly melted when it is heated by electricity. Compared with the entire connecting piece being made of a burnable material, the first connecting part 301 and the second connecting part 303 are made of a stronger material, which can ensure a stable connection between the connecting piece and the first protruding part 1011 and the second protruding part 201. During the melting process, since only the fuse part 302 is burned, relatively less smoke, toxic substances and heat are generated. This reduces the risk of fire and other safety accidents.

[0035] The side wall of the first protruding member 1011 is provided with a first groove 1012 , which is matched with the first connecting portion 301 . The side wall of the second protruding member 201 is provided with a second groove 202 , which is matched with the second connecting portion 303 .

[0036] The first groove 1012 and the second groove 202 allow the first connection part 301 and the second connection part 303 of the connector 3 to be tightly embedded therein, thereby ensuring the stability of the connection and effectively preventing the connector from loosening or falling off when subjected to external force or vibration.

[0037] In normal use, the first connection part 301 and the second connection part 303 of the connecting member 3 are respectively fixed in the grooves of the first protruding member 1011 and the second protruding member 201, ensuring a tight connection between the gas outlet 101 and the pressing member 2. When it is necessary to release the gas, the electronic heating component 4 is started by the switch 402, and the electric heating wire 401 starts to heat. The heat is transferred to the fuse part 302, causing it to melt quickly. Due to the melting of the fuse part 302, the connecting member 3 is broken, the pressing member 2 loses connection and is released, and the gas is ejected from the gas outlet 101.

[0038] Embodiment 4: In a possible implementation manner, as Figure 4 As shown, an annular sealing ring 203 is provided at the bottom of the pressing member 2, the size of the annular sealing ring 203 is adapted to the air outlet 101, and the annular sealing ring 203 is sleeved on the air outlet 101. The annular sealing ring can be made of elastic material, such as rubber.

[0039] For reference, a connecting rod with an L-shaped cross-section may be provided on a side wall of the air outlet 101 away from the first protrusion 1011, and the connecting rod includes a horizontal portion and a vertical portion. The horizontal portion of the connecting rod is connected to the side wall of the air outlet 101, one end of the vertical portion is connected to the horizontal portion, and the other end of the vertical portion is hinged to the clamping member 2. There is a gap between the vertical portion and the side wall of the air outlet 101, and the gap is for allowing an annular sealing ring to be mounted on the air outlet.

[0040] Embodiment 5: In a possible implementation manner, as Figure 5 The fuse part 302 is provided with a wire threading hole 304 , a lead wire 305 is provided in the wire threading hole 304 , and the lead wire 305 is connected to the electric heating wire 401 .

[0041] For reference, one end of the lead wire 305 can be wound around the fuse 302 through the threading hole 304, and the other end of the lead wire 305 is wound and tied to the electric heating wire 401. According to the above embodiment, the other end of the lead wire 305 is wound and tied to the electric heating wire. The lead wire 305 is made of a material that is easy to burn, such as cotton thread or cotton yarn. It should be noted that the selection of the resistance value of the heating wire and the voltage of the power supply need to meet the requirements that the temperature of the heating wire is higher than the ignition point of the lead wire 305, and the specific parameters of the heating wire and the power supply voltage can be selected as needed.

[0042] Embodiment 6: In a possible implementation manner, Figure 6As shown, the top of the gas storage member 1 is surrounded by a cylinder 5, and the gas outlet 101 is located below the cylinder 5. The cylinder 5 is used to store fillers. The fillers can be colored confetti. It is understood that the bottom of the cylinder 5 is connected to the gas outlet 101, and there is a net between the cylinder 5 and the gas outlet 101 to prevent the confetti from falling near the gas outlet 101. A thin paper cover is installed on the top of the cylinder 5.

[0043] In this embodiment, the gas storage member 1 is pre-filled with compressed gas, and the cylinder 5 is also filled with colored confetti as filler. During operation, once the switch 402 is activated, the electric heating wire 401 is rapidly heated and transfers heat to the fuse 302, causing the connector 3 to break. As the free end of the pressing member 2 is released, the high-pressure gas inside the gas storage member 1 instantly rushes out of the gas outlet 101. At this time, the colored confetti in the cylinder 5 located at the top of the gas storage member is strongly pushed by the gas and ejected along with the gas. The thin paper cover will be pushed open under the gas pressure, similar to the blooming of traditional fireworks. The high-speed flow of gas not only brings out the confetti, but also may produce additional sound effects due to the interaction between the airflow and the confetti.

[0044] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
