A switch 13 for controlling the electric push rod is installed above the front wall of the handle 11. The electric push rod 13 can be turned on or off by the switch 13, and the extension and retraction speed of the electric push rod 5 can be adjusted into three gears by the switch, thereby realizing the adjustment of the sugar output speed and sugar output amount. The switch 13 and the electric push rod 5 are both existing products.

[0024] A charging port 14 for charging is fixedly installed at the bottom of the handle 11, and a power supply 15 for energy supply is fixedly installed inside the handle 11. The charging port 14 is connected to the power supply 15, and the power supply 15 supplies energy to the device, including supplying energy to the following parts: the heating tube 2 heats and melts the sugar material, the insulation tube 3 maintains a certain temperature to prevent the sugar water from solidifying again, and the electric push rod 5 pushes and squeezes out the sugar water. The charging port 14 and the power supply 15 are both existing products.

[0025] The inner wall of the housing 1 is provided with a heat insulating layer to prevent the housing 1 from being overheated due to heat transfer and thus scalding the user.

[0026] A sugar outlet 21 is fixedly connected to the heating tube 2, and the sugar outlet 21 is perpendicular to the heating tube 2. The sugar outlet 21 extends out of the upper outer wall of the shell 1. A sealing cover 22 is provided at the opening of the sugar outlet 21. By opening the sealing cover 22, sugar to be melted can be added to the heating tube 2. The sealing cover 22 is closed at other times, which can not only improve the melting efficiency, but also prevent foreign matter from entering the sugar water and affecting the quality of the sugar painting.

[0027] A heating wire is installed on the outer wall of the heating tube 2. The heating wire generates heat and heats up the heating tube through heat transfer, thereby melting the sugar material. The heating wire is flush with the outer wall of the heating tube 2.

[0028] A partition piece is fixedly connected to the interior of the housing 1 near the rear end, and a cavity for installing the first cleaning component 23 is formed between the partition piece and the housing 1. The upper wall of the cavity is concave to form a sliding groove 12.

[0029] The rear end of the heating tube 2 is closed, and the first cleaning component 23 passes through the partition plate and the rear end of the heating tube 2 in sequence and extends into the interior of the heating tube 2. At the same time, under normal circumstances, no external force is applied. The first cleaning component 23 is located at the rear end of the sugar outlet 21 and will not affect the normal placement of sugar.

[0030] The first cleaning assembly 23 includes a piston rod 232 and a first piston 234 connected to one end of the piston rod 232. The piston rod 232 passes through and extends into the inner wall of the heating tube 2. The first piston 234 is located at the rear end of the interior of the heating tube 2 and fits against the inner wall of the heating tube 2.

[0031] The other end of the piston rod 232 is fixedly connected to the shift rod 231. The shift rod 231 is located in the slide groove 12, and the upper end of the shift rod 231 extends out of the slide groove 12 and is located outside the upper wall of the shell 1. The first pressure spring 233 is sleeved on the piston rod 232, and the two ends of the first pressure spring 233 are respectively fitted with the shift rod 231 and the partition piece.

[0032] The working principle of the first cleaning component 23 is as follows: manually push the lever 231 to slide forward along the slide groove 12, the first pressure spring 233 is compressed, and the first piston 234 moves forward, pushing the melted sugar water forward, and also pushing part of the sugar water stained on the inner wall forward to avoid residue and reduce waste. After the first cleaning component 23 is completed, release the lever 231, the first pressure spring 233 is reset, and the first piston 234 is also reset and returns to the vicinity of the rear end of the heating tube 2.

[0033] The inner wall of the heating tube 2 is smooth and not easy to stick to sugar water. In conjunction with the first cleaning component 23, sugar water residue can be avoided to the greatest extent, so that the quality of each sugar painting can be guaranteed, avoiding the reduction of sugar painting quality due to residue, or even affecting human health when consumed.

[0034] The front end of the heating tube 2 is connected to the upper end of one side of the connecting part 3 , and when the first cleaning assembly 23 moves to the limit, the front wall of the first piston 234 is flush with the inner wall of the connecting part 3 .

[0035] A second cleaning assembly 31 is installed inside the connecting portion 3. The second cleaning assembly 31 includes a scraper 314. The scraper 314 is located inside the movable portion 3. The cross section of the scraper 314 is arc-shaped. Both sides of the scraper 314 are vertically downward and fit against the inner wall of the connecting portion 3.

[0036] The upper end of the scraper 314 is fixedly installed with a connecting rod 312, which passes through and extends out of the upper wall of the shell 1, and is connected to the pressure block 311. The second pressure spring 313 is sleeved on the connecting rod 312, and the second pressure spring 313 is respectively fitted with the shell 1 and the pressure block 311.

[0037] The working principle of the second cleaning component 31 is: manually press the pressure block 311 to make it move vertically downward, the second pressure spring 313 is compressed, and the scraper 314 moves downward to scrape off part of the sugar water contaminated on the inner wall of the connecting part 3 and the sugar water contaminated on the front wall of the first piston 234 to avoid residue. After the second cleaning component 31 completes its work, release the pressure block 311, the second pressure spring 313 is reset, and the scraper 314 is also reset.

[0038] It should be noted that, at this time, the scraper 314 is located above the first piston 234 .

[0039] The front end of the insulation tube 4 extends out of the shell 1 for a distance and is used to connect with the gun head 41. The gun head 41 is threadedly connected to the front end of the insulation tube 4. A sugar outlet is provided on the gun head 41 for flowing out the sugar water. The gun head 41 is detachable, which is convenient for timely cleaning after use to avoid sugar water residue. At the same time, other gun heads 41 with different sizes of sugar outlets can be replaced to facilitate drawing different sugar paintings. When not in use, the gun head without a sugar outlet can be replaced to prevent foreign matter and dust from entering and contaminating the sugar painting.

[0040] The other end of the insulation tube 4 is connected to the lower end of the other side of the connecting part 3. The outer walls of the connecting part 3 and the insulation tube 4 are also installed with a heating wire. The heating wire generates heat and maintains the dimensions of the connecting part 3 and the insulation tube 4 within a suitable range through heat transfer to prevent the sugar water from solidifying. The heating wire is flush with the outer walls of the connecting part 3 and the insulation tube 4.

[0041] The inner wall material of the connecting part 3 and the insulation tube 4 is the same as the inner wall material of the heating tube 2. The heating wires of the heating tube 2, the connecting part 3 and the insulation tube 4 are powered by the power supply 15 and are controlled to be turned on or off by other external switch components.

[0042] The electric push rod 5 is fixedly installed below the heating tube 2 and is at the same horizontal height as the insulation tube 4. The movable end of the electric push rod 5 is fixedly connected to the second piston 51. The second piston 51 extends into the connecting part 3 and the front wall of the second piston 51 is flush with the rear wall of the connecting part 3.

[0043] The curvature of the scraper 314 matches that of the second piston 51 . When the second cleaning assembly 31 moves to the limit, the lower wall of the scraper 314 just fits against the side wall of the second piston 51 .

[0044] When the second piston 51 moves forward, it will scrape off the sugar water adhered to the connecting part 3 and the lower wall of the scraper 314, and push it out together to flow out from the sugar outlet. This not only maximizes the utilization rate, but also reduces residue, improves the safety quality of sugar painting, and avoids affecting human health.

[0045] When the second piston 51 moves to the limit, it is flush with the front end of the insulation tube 4. After removing the gun head 41, it is easy to clean without any residue inside, avoiding affecting human health.

[0046] A method of using a sugar painting gun according to this embodiment is as follows:

[0047] Open the sealing cover 22, put the sugar into the heating tube 2 from the sugar outlet 21, then turn on the heating wires of the heating tube 2, the connecting part 3 and the insulation tube 4, and heat transfer to increase the temperature. The sugar melts and flows from the heating tube 2 through the connecting part 3 and finally into the insulation tube 4. Then manually push the lever 231 to slide forward along the slide groove 12, the first pressure spring 233 is compressed, and the first piston 234 moves forward, pushing the remaining sugar water forward until it moves to the limit state. Then manually press the pressing block 311 to make it move vertically downward, and the second pressure spring 233 is compressed. The spring 313 is compressed, and the scraper 314 moves downward to scrape off the syrup remaining on the inner wall of the connecting part 3 and the front wall of the first piston 234. The lever 231 is released, the first pressure spring 233 is reset, the first piston 234 is reset, and the heating wire of the heating tube 2 is turned off. The switch 13 is pressed, and the electric push rod 5 pushes the second piston 51 forward to push all the syrup remaining on the inner wall of the connecting part 3 and the scraper 314 into the insulation tube 4. The pressing block 311 is released, the second pressure spring 313 is reset, the scraper 314 is also reset, and the heating wire of the connecting part 3 is turned off.

[0048] Then, the extension and retraction speed of the electric push rod 5 is adjusted as needed to achieve more precise adjustment of the sugar dispensing speed and sugar dispensing amount. The sugar solution flows out of the sugar dispensing port of the gun head 41 more evenly, and the sugar painting is more exquisite. After the saccharification is completed, all the sugar solution in the insulation tube 4 is pushed out, the heating wire of the insulation tube 4 is turned off, the gun head 41 is removed, and the gun head 41 and the second piston 51 are then cleaned. After completion, the electric push rod 5 is activated to reset the second piston 51, and a new gun head 41 is replaced for subsequent use.

[0049] The above embodiments are only for illustrating the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention.
