Description
Technical Field
[0001] This utility model relates to the field of baking pan machine technology, and in particular to a handheld mini vacuum baking pan machine. Background Technology
[0002] A heat transfer baking machine can print any color mark, portrait photo, landscape pattern, etc., onto a ceramic plate, making it particularly suitable for advertising, gifts, and promotional activities. It can also be used to create personalized items, combining artistic appreciation and practicality.
[0003] A baking tray machine generally consists of a frame, a lower support plate, and an upper heating plate. Based on the power source that drives the upper heating plate to open, it is divided into manual and automatic types. Manual baking tray machines typically use a robotic arm and spring pressure to bake the tray. Due to their lower cost, they are generally suitable for DIY enthusiasts and small-batch production. For large-scale industrial production, automatic baking tray machines are used. Automatic baking tray machines generally use a hydraulic system or pneumatic pressure to achieve the clamping action between the upper heating plate and the lower support plate. To better control the baking time and temperature, both electric and manual baking tray machines are equipped with a digital display temperature control system.
[0004] However, in all of the aforementioned baking pan machines, whether manual or automatic, the upper heating plate needs to repeatedly contact and press down on the lower support plate, necessitating an increased displacement stroke of the upper heating plate. The frame structure also requires adaptive adjustments, resulting in increased space and weight, and a less aesthetically pleasing appearance. Furthermore, these baking pan machines are inconvenient to move or carry, making them unsuitable for home use and limiting their market competitiveness. Utility Model Content

[0029] 1. A cleverly designed air pump and vent valve are installed inside the casing, and the air pump's air pipe is connected to the air nozzle located at the top of the base. When a baking tray is needed, the base is first placed on top of the tray, with the sealing ring at the bottom of the base abutting against the edge of the tray. The air pump evacuates the inside of the base, forming a vacuum chamber. The sealing ring ensures the airtightness of the vacuum chamber. At this time, the external atmospheric pressure can firmly press the base down on top of the tray, causing the sealing ring to deform. The heating element abuts against the surface of the tray and performs heat transfer, resulting in a good heat transfer effect.
[0030] 2. The casing serves only to provide gripping and mounting space for the integrated circuit board, air pump, vent valve, and touch panel. Therefore, the machine can be made very small, lightweight, mini, and easy to move, making it suitable for home use. Attached Figure Description

[0047] Detailed implementation plan: See below Figures 1-10 This utility model is a portable mini vacuum baking pan machine, comprising:
[0048] The base 1 has an internal insulation cotton 8 and a heating element 9, wherein the insulation cotton 8 is located above the heating element 9, the upper end of the base 1 is provided with an air nozzle 11, and the lower edge of the base 1 is provided with a soft sealing ring 13.
[0049] Housing 2 is mounted above base 1;
[0050] Air pump 4 is installed inside housing 2, and one end of the air pipe on air pump 4 is connected to air nozzle 11;
[0051] The vent valve 5 is installed inside the housing 2 and is located in the air circuit of the air pump 4;
[0052] Touchpad 10 is mounted on housing 2;
[0053] The integrated circuit board 3 is fixed in the housing 2. The air pump 4, the air release valve 5, the heating element 9 and the touch panel 10 are all electrically connected to the integrated circuit board 3.
[0054] The vacuum baking pan machine is in working condition. In working condition, the sealing ring 13 abuts against the upper edge of the pan, and the air pump 4 evacuates the inside of the base 1 to form a vacuum chamber 14, which is located above the insulation cotton 8.
[0055] As a preferred embodiment of this example, see [link to previous document]. Figure 1 and Figure 4 As can be seen, the casing 2 has a hand grip opening 25 for hand gripping.
[0056] Then, please see Figure 5 As can be seen, in this embodiment, the housing 2 includes:
[0057] The lower housing 21 is installed above the base 1;
[0058] The upper cover 24 is installed above the lower housing 21;
[0059] Mounting bracket 22 is positioned above the lower housing 21 and arranged inside the upper housing 24;
[0060] Two hand-held brackets 23 are respectively set on the left and right sides of the mounting bracket 22, and the two hand-held brackets 23 work together to form a hand grip opening 25.
[0061] Here, the housing 2 is designed as a detachable structure, partly to facilitate mold making, and partly to facilitate product assembly and disassembly. In this embodiment, the handheld bracket 23 is provided with multiple buckles, the mounting bracket 22 is provided with multiple latches, and the upper cover 24 is also provided with buckles or...
[0062] The handheld bracket 23 is connected to the mounting bracket 22 and the upper cover 24 through the snap-fit and snap-fit, which makes the structure of the housing 2 very stable.
[0063] Of course, in practical applications, the upper cover 24, the mounting bracket 22 and the handheld bracket 23 can also be designed as an integrated structure.
[0064] Please see Figure 6 In this embodiment, it can be seen that the air pump 4, the vent valve 5, and the integrated circuit board 3 are all installed inside the lower housing 21. Please refer to [link / reference]. Figure 1 and Figure 7 As can be seen, the touchpad 10 is installed inside the upper cover 24, and the touchpad 10 is provided with several control buttons 101, which extend to the outside of the front surface of the upper cover 24.
[0065] Here, users can control the start / stop of the device, the heating temperature, and the heating time by operating the control button 101.
[0066] Next, please refer to Figure 8 and Figure 9 As can be seen, in this embodiment, a heat insulation pad 6 and an intermediate pad 7 are provided between the lower housing 21 and the base 1, wherein the intermediate pad 7 is placed on the upper surface of the base 1 and the heat insulation pad 6 is placed above the intermediate pad 7.
[0067] Here, the design of the heat insulation pad 6 and the intermediate pad 7 prevents the temperature emitted by the heating element 9 from affecting the parts located in the housing 2, ensuring that the product's lifespan is not affected. The design of the insulation cotton 8 maintains the temperature of the heating element 9, thereby reducing energy consumption and improving the quality of heat transfer printing.
[0068] Please see Figure 10In this embodiment, since the heating element 9 is located below the base 1 and the integrated circuit board 3 is located above the base 1, a wire channel 12 for power supply wiring needs to be provided on the base 1 to electrically connect the integrated circuit board 3 and the heating element 9. Furthermore, to ensure the airtightness of the base 1 during the vacuuming process using the air pump 4, a sealing plug is installed on the wire channel 12 on the base 1 in this embodiment.
[0069] Overall, the pan-fryer in this embodiment resembles a vacuum suction cup. The difference is that a conventional vacuum suction cup uses an external air pump 4 to extract air from its interior to create negative pressure. However, in this embodiment, the air pump 4 is installed inside the casing 2, and the base 1 acts as the suction cup. When the base 1 is evacuated by the air pump 4, the external atmospheric pressure firmly presses the base 1 down onto the pan.
[0070] In addition, please see Figure 7 As can be seen in this embodiment, the upper end of the lower housing 21 is provided with a protrusion and a force-bearing plane 211 disposed around the protrusion. The upper cover 24 is installed above the protrusion, and the air pump 4, the vent valve 5, and the integrated circuit board 3 are all installed inside the protrusion. The design of the force-bearing plane 211 on the base 1 allows more atmospheric pressure to be pressed vertically downward onto the base 1, thereby allowing the base 1 to press down better on the plate.
[0071] Next, please refer to Figure 3 and Figure 4 As can be seen, in this embodiment, the sealing ring 13 extends obliquely with a smaller upper port diameter and a larger lower port diameter.
[0072] Note that in this embodiment, the sealing ring 13 is made of soft rubber, such as silicone or rubber.
[0073] In addition, by designing the sealing ring 13 at an angle, it is easy to attach it directly to the upper edge of the plate. In this way, even if the sealing ring 13 is deformed during the pressing of the base 1, it will still stick tightly to the plate.
[0074] More preferably, a power cord 26 for use with an external power supply is provided on the rear side of the housing 2.
[0075] The following explains the entire process of completing a plate heat transfer:
[0076] 1. The user sets the preheating temperature, starts the baking pan machine, and the heating element 9 heats up to the set temperature;
[0077] 2. Place the plate with the heat transfer film on a flat surface. The user holds the baking machine through the handle 25 and places the base 1 of the baking machine directly above the plate. At this time, the sealing ring 13 on the base 1 is attached to the upper edge of the plate.
[0078] 3. Start the air pump 4. The air pump 4 will evacuate the inside of the base 1. The external atmospheric pressure will press the base 1 down onto the plate. As the base 1 is pressed down, the heating element 9 in the base 1 will press tightly against the area of the plate that needs to be heat transferred (during this process, the sealing ring 13 will keep in contact with the edge of the plate).
[0079] 4. After the set transfer time is reached, the vent valve 5 starts to work and releases the vacuum inside the base 1 until the air pressure inside the base 1 returns to atmospheric pressure. The user can then hold the baking pan and lift it upwards off the plate to complete the transfer.
[0080] The above description of the portable mini vacuum baking pan machine of this utility model is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made under the inventive concept of this utility model using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of this utility model.
