The heating assembly 20 is arranged along a second direction. The first end of the heating assembly 20 is connected to the material box assembly 10, and the second end of the heating assembly 20 is connected to the spray pipe assembly 40. The air outlet of the fan system 30 is connected to the spray pipe assembly 40. The first direction and the second direction are different.

[0033] The working principle of the embodiment of the present application can be seen in the following description:

[0034] The cold flame spray gun provided in the embodiment of the present application includes: a material box assembly 10, a heating assembly 20, a fan system 30 and a spray pipe assembly 40. The metal powder in the material box assembly 10 can be ignited at high temperature by the heating assembly 20 and then enter the spray pipe assembly 40. Under the blowing action of the fan system 30, the ignited metal powder can be blown out of the spray pipe assembly 40 to form fireworks. In this way, the above-mentioned cold flame spray gun has a simple structure and a small size, so that it is easy to carry, that is, the above-mentioned cold flame spray gun has good portability.

[0035] That is to say, metal powder can enter the material box assembly 10 from the feed port, and then enter the heating assembly 20 through the material box assembly 10. The heating assembly 20 can ignite the metal powder by high temperature. The ignited metal powder can enter the spray tube assembly 40, and under the blowing action of the fan system 30, the ignited metal powder can be blown out by the spray tube assembly 40 to the external environment to form a cold flame. The above-mentioned cold flame spray gun has a simple structure and a small size, so that the above-mentioned cold flame spray gun has better portability, and the cold flame spray gun does not need to be limited to a fixed place for use, and can be used in multiple scenes, and the degree of freedom of the use scene is relatively high.

[0036] In addition, it should be noted that, due to the simple structure of the cold flame spray gun provided in the embodiment of the present application, the failure rate is low, resulting in a relatively stable cold flame spraying effect and better performance.

[0037] Among them, see Figure 1 The cold flame spray gun may further include a housing 100, which may be gun-shaped, and the gun-shaped housing may include a housing cavity, and the above-mentioned material box assembly 10, heating assembly 20, fan system 30 and spray pipe assembly 40 and other components may be arranged in the housing cavity. Since the housing 100 of the cold flame spray gun is gun-shaped, the portability of the cold flame spray gun can be further enhanced.

[0038] Optionally, the feed port may be a funnel-shaped feed port, so that a better feeding effect of the metal powder can be ensured and the occurrence of the phenomenon that the metal powder is spilled into the external environment when entering the feed box assembly 10 through the feed port can be reduced.

[0039] Among them, the first direction and the second direction are not specifically limited here, the first direction and the second direction are different, and thus there is an angle between the first direction and the second direction; optionally, the first direction can be a horizontal direction, and the second direction can be a vertical direction; optionally, the first direction can be a vertical direction, and the second direction can be a horizontal direction.

[0040] As an optional implementation, see Figure 2 The heating component 20 includes a heating coil 21 and a transmission tube 22. The heating coil 21 is sleeved on the transmission tube 22. The first end of the transmission tube 22 is connected to the material box component 10, and the second end of the transmission tube 22 is connected to the spray tube component 40.

[0041] In the embodiment of the present application, the metal powder can pass through the material box assembly 10, the transmission pipe 22 and the spray pipe assembly 40 in sequence, and under the blowing action of the fan system 30, the metal powder can be blown out of the spray pipe assembly 40.

[0042] In addition, when the metal powder passes through the transmission tube 22, the heating coil 21 can ignite the metal powder in the transmission tube 22 at high temperature, that is, the high temperature ignition of the metal powder can be achieved without contacting the metal powder, thereby enhancing safety performance.

[0043] As an optional implementation, see Figure 1 The heating component 20 also includes a heat insulating member 23 , and the heat insulating member 23 is sleeved on the heating coil 21 .

[0044] In the embodiment of the present application, since the thermal insulation member 23 is sleeved on the heating coil 21, it can have a thermal insulation effect on the heating coil 21, that is, the heat of the heating coil 21 can be concentrated in the thermal insulation member 23, so that the heat of the heating coil 21 can be used as much as possible to ignite the metal powder at high temperature, thereby enhancing the ignition effect on the metal powder.

[0045] In addition, the heat insulating member 23 can also reduce the heat of the heating coil 21 being transferred to other components of the cold flame spray gun, thereby reducing the occurrence of damage to other components.

[0046] As an optional implementation, the heating component 20 further includes a first temperature sensor, and the first temperature sensor is arranged opposite to the heating coil 21 .

[0047] In the embodiment of the present application, the first temperature sensor is arranged opposite to the heating coil 21, so that it can be used to detect the temperature of the heating coil 21. When the temperature of the heating coil 21 exceeds the first preset temperature, the cold flame spray gun can be controlled to stop working to prevent the internal components of the cold flame spray gun from being damaged due to excessive temperature.

[0048] In addition, when the temperature of the heating coil 21 exceeds the second preset temperature, a prompt message may be output, where the prompt message is used to remind the user that there is an abnormality in the heating coil 21 and the heating coil 21 needs to be repaired or replaced.

[0051] In the embodiment of the present application, the feeding motor 24 drives the transmission screw 25 to move along the second direction, thereby driving the metal powder to move along the second direction in the transmission tube 22, and then the metal powder can be moved from the transmission tube 22 to the spray tube assembly 40, thereby enhancing the driving effect on the metal powder.

[0052] As an optional implementation, see Figure 2 The material box assembly 10 includes a material storage box 11 and a material discharge motor 12. The feed port is opened on the material storage box 11. The output end of the material discharge motor 12 is passed through a receiving groove 111 in the material storage box 11, and the output end of the material discharge motor 12 can move along the receiving groove 111. The receiving groove 111 is connected to the first end of the heating component 20.

[0053] In the embodiment of the present application, the output shaft of the unloading motor 12 can move along the receiving groove 111 and drive the metal powder to move along the receiving groove 111, so that the metal powder can move from the receiving groove 111 to the heating component 20, thereby enhancing the driving effect on the metal powder.

[0054] As an optional implementation, the transmission pipe 22 is a three-way transmission pipe, and the third end of the transmission pipe 22 is connected to the transmission screw 25 .

[0055] Among them, the three-way transmission pipe can also be called a three-way pipe.

[0056] In the embodiment of the present application, the transmission tube 22 is a three-way transmission tube, and the third end of the transmission tube 22 is connected to the transmission screw 25 , so that the transmission screw 25 can better drive the metal powder to move in the transmission tube 22 .

[0060] Wherein, when the second control switch 60 and the first control switch 50 are both in the on state, the second control switch 60 and the first control switch 50 are used to control the fan system 30 to blow the metal powder out of the spray pipe assembly 40 to form fireworks;

[0061] When the second control switch 60 is in the off state, the second control switch 60 is used to prohibit the fan system 30 from blowing the metal powder out of the spray pipe assembly 40 .

[0062] The specific types of the first control switch 50 and the second control switch 60 are not limited herein. Optionally, the first control switch 50 is a trigger type, and the second control switch 60 is a button type.
