[0040] Referring to FIG. 1 to FIG. 8, the present disclosure provides a portable thermal printing device 100, and the portable thermal printing device 100 is used in combination with a mold and a foil or a piece of paper to achieve Do It Yourself (DIY) type thermal printing operations. A rolling process is specifically carried out in combination with a rolling device 200. It may be understood that the rolling process may also be carried out by other devices capable of providing a pressure.

The Portable Thermal Printing Device 100 Specifically Includes:

[0041] a support plate assembly 10; [0042] a heat insulation plate 20 disposed on the support plate assembly 10; and [0043] a heating plate 30 disposed on the heat insulation plate 20 and including a uniform heating plate body, a covering layer, and a heating element disposed between the uniform heating plate body and the covering layer, where the heating plate is configured to heat a thermal printing assembly.

[0044] In this embodiment, the support plate assembly 10, the heat insulation plate 20, and the heating plate 30 are distributed sequentially from bottom to top. The heating plate 30 at the upper side is configured to heat the thermal printing assembly, and the heat insulation plate 20 at the lower side is configured to prevent the heat of the heating plate 30 from being transferred to the lower side, thereby avoiding heat loss and improving the heating efficiency. Further, the heating plate 30 is disposed on the uniform heating plate body to achieve overall rapid heating of the heating plate, thereby further improving the heating efficiency.

[0045] The heating plate 30 is of an integrated structure. The heating element is closely disposed on a side of the uniform heating plate body. The covering layer correspondingly covers the side of the uniform heating plate body where the heating element is arranged, and the three are integrated. Not only is stable connection achieved, but also the heat conduction performance is also high. Compared with a conventional heating plate, the heating plate of the present disclosure has obvious advantages.

[0046] The support plate assembly 10 is connected to the heat insulation plate 20 via a fastener. Specifically, the fastener is a screw which passes through the support plate assembly 10 and is locked into the heat insulation plate 20. It may be understood that the fastener can also pass through the heat insulation plate 20 and is locked into the heating plate 30.

[0047] Further, the uniform heating plate body is connected side by side to the heat insulation plate 20, and the covering layer is in contact with the thermal printing assembly. In this embodiment, the uniform heating plate body is disposed at the lower side and connected side by side to the heat insulation plate 20. The heating element is disposed on the uniform heating plate body. The uniform heating plate body may accelerate the overall heating of the plate body and can form a stable support structure with the heat insulation plate 20 and further with the support plate assembly 10.

[0048] Further, the uniform heating plate body is a plate body made of a material with high thermal conductivity. Commonly, it is a metallic plate body, such as an aluminum plate, a copper plate, or a stainless steel plate. The aluminum plate is an aluminum alloy plate, and the copper plate is a copper alloy plate.

[0049] Further, the heating element is one of a resistance wire, a reticular heating body, and a resistance element formed by sintering from a resistance paste, where the resistance wire, the reticular heating body, and the resistance element are distributed on the uniform heating plate body.

[0050] Further, the covering layer is one of a silicone coating, a thermoplastic elastomer coating, a polyurethane coating, a biological resin coating, and a polypropylene coating. The covering layer is configured to transfer the heat of the heating element upwards to the thermal printing assembly, and has certain elasticity rather than rigidity. Thus, during contacting with the thermal printing assembly, the risk of unstable plate contact due to a local pressure can be avoided.

[0051] Further, the covering layer is provided with location referencing lines for providing a position reference when the thermal printing assembly is placed.

[0052] Further, the portable thermal printing device 100 includes an electrical connection element 40 detachably connected to the heating element via magnetic attraction and configured to connect to an external power source and supply power to the heating element.

[0053] In this embodiment, the electrical connection element 40 is connected to the external power source and connected, via magnetic attraction, to the heating element 32 for supplying power. This is convenient for the operating device to switch between a powered-on heating state and a powered-off transfer printing state.

[0054] Further, the portable thermal printing device 100 includes a circuit board 50 disposed on the support plate assembly 10. The heating element 32 is electrically connected to the circuit board 50. A magnetic attracting connector 51 is disposed on the circuit board 50. The electrical connection element 40 is fit with the magnetic attracting connector 51 via magnetic attraction. The electrical connection element 40 is configured to supply power to the heating element via the circuit board 50. Specifically, the electrical connection element 40 and the magnetic attracting connector 51 are provided with corresponding magnetic chucks, facilitating corresponding operations and stable connection. In this embodiment, the circuit board 50, as a control core of the device, can control the operation of the device, e.g., control a heating temperature and a temperature holding time of the heating element 32, power-off protection in emergencies, etc. It may be understood that the circuit board may be omitted such that the heating element 32 is directly connected to the external power source via the electrical connection element 40 for heating. A user may start or stop heating according to an actual operation situation, and further conduct a rolling transfer printing operation.

[0055] Further, the circuit board 50 includes a DC-DC conversion module configured to receive an external DC voltage and convert the DC voltage to a predetermined DC voltage. Thus, the circuit board 50 may be fit with a plurality of power adapters. Furthermore, discharge of an electronic device (e.g., a mobile phone or a tablet computer) may also be used for supplying power.

[0056] Further, the support plate assembly 10 includes a support plate 11 disposed under the heat insulation plate 20 and a bottom plate 12 disposed under the support plate 11. The bottom plate 12 includes a supporting bottom plate 121 corresponding to the support plate 11 and a support frame 122 surrounding the supporting bottom plate 121. The circuit board 50 is disposed within the support frame 122. The magnetic attracting connector 51 is exposed from the support frame 122. In this embodiment, the support plate assembly 10 is of an assembly structure to serve as a support structure for the entire portable thermal printing device 100. Moreover, the support frame 122 is formed, which has a mounting space formed therein. The mounting space is adapted to mount the circuit board 50, the magnetic attracting connector 51, a key structure, and the like. Thus, the whole functions of the portable thermal printing device 100 are increased, and a relatively simple structural form is maintained.

[0057] The support frame 122 surrounds the supporting bottom plate 121 to form an accommodating space. Correspondingly, the heat insulation plate 20, the heating plate 30, the mold, and the foil can all be disposed within the receiving space such that the component structures are stable, thereby avoiding misalignment during the thermal printing process.

[0058] Further, the support frame 122 extends at one end of the supporting bottom plate 121 to form a handle frame 123. A gripping opening 124 is formed in the handle frame 123. In this embodiment, the support frame 122 is further formed as a structure convenient for gripping, thereby further improving the portability.

[0059] Further, the bottom plate 12 is provided with a heat dissipation structure 125. The bottom plate 12 is an opposite side of heat transfer printing, and the heat flowing therethrough is heat ineffective to the thermal printing process. In order to maintain long-term stable operation of the device, it is advantageous to provide the heat dissipation structure 125 accordingly. Specifically, the heat dissipation structure 125 may be a hollowed-out frame structure.

[0060] Further, the portable thermal printing device 100 includes a buzzer (not shown) electrically connected to the circuit board 50 and configured to produce a buzzing prompt sound. The buzzer may be configured for timing and prompting. For example, the buzzing prompt sound is provided after heating for a certain time.

[0061] Further, the portable thermal printing device 100 includes a key module 60 disposed on the support plate assembly 10 and electrically connected to the circuit board 50. The key module 60 is configured for a user to press keys to perform operations, such as starting heating, stopping heating, and setting a heating time or a heating temperature.

[0062] Further, the portable thermal printing device 100 includes a thermal printing assembly. The thermal printing assembly includes a thermal printing template 70, a thermal printing paper 80, and a hard paper board 90 that are stacked in sequence. The thermal printing template 70 can be disposed on the heating plate 30. The thermal printing paper 80 may be a metal foil, such as an aluminum foil.

[0063] The portable thermal printing device 100 is configured to apply a pressure to the hard paper board 90 by one of manual pressing equipment, isostatic pressing equipment, or a rolling device 200 such that a pattern of the thermal printing template is transfer-printed onto the thermal printing paper 80. In a preferred embodiment, the portable rolling device 200 is configured to be used in combination with the portable thermal printing device 100.

[0064] Further, the portable thermal printing device 100 includes a bearing base 95 disposed under the support plate assembly 10. The bearing base 95 is configured to bear an external pressure applied to the portable thermal printing device 100. Specifically, external pressure equipment is in contact with the hard paper board 90 to apply a pressure, such as a rolling pressure or a static pressure, such that the portable thermal printing device 100 performs the transfer printing operation. The bearing base 95 provides a bearing force at the lower side.

[0065] The bearing base 95 includes a pressure bearing plate 96 and a limiting edge 97 extending from a periphery of the pressure bearing plate 96 towards the support plate assembly. The support plate assembly 10 corresponds to a space between the pressure bearing plate 96 and the limiting edge 97. The pressure bearing plate 96 is configured to provide a bearing force.

[0066] Further, the heat insulation plate 20 includes one of an aerogel plate, a vacuum thermal isolation plate, a polyurethane rigid foam plate, an expanded polystyrene plate, and an extruded polystyrene plate.

[0067] Further, the support plate assembly 10 is made of a material of one of phenolic plastics, epoxy resin, urea resin, melamine formaldehyde resin, polypropylene, polyvinyl chloride, and polystyrene.

[0068] Further, the rolling device 200 includes a housing 201, two silicone rollers (not shown) disposed within the housing 201, and a rotary operating element 202 disposed on the housing 201 and linked with one silicone roller. A rolling space (not shown) is formed between the two silicone rollers. The housing 201 is provided with a rolling opening 203 communicating with the rolling space. The portable thermal printing device 100 is capable of entering or being disengaged from the rolling space through the rolling opening 203. A bearing element 204 is further disposed outside the housing 201 corresponding to the rolling opening 203. In this embodiment, a user controls the rotary operating element 202 to rotate, driving one silicone roller to rotate. At the connection point of one end of the portable thermal printing device 100 with the silicone roller, the silicone roller rotates to enter the corresponding rolling space. When the portable thermal printing device 100 passes through the rolling opening 203 and the rolling space, the rotary operating element 202 is operated reversely such that the portable thermal printing device 100 moves reversely relative to the silicone roller, thereby realizing roller return and completing the rolling process.

[0069] The portable thermal printing device of the present disclosure is provided with the miniaturized support plate assembly 10, heat insulation plate 20, and heating plate 30, and the heating plate 30 is provided with the uniform heating plate body, the covering layer, and the heating element disposed therebetween. During the heating process, on the one hand, the overall heating of the heating plate can be accelerated with the uniform heating plate body, achieving effective heating; and on the other hand, ineffective heating caused by heat loss can be reduced.

[0070] It should be further noted that, in this description, relationship terms such as first and second are only used to distinguish an entity or operation from another entity or operation, but do not necessarily require or imply that there is any actual relationship or order between these entities or operations. In addition, terms include, comprise, or any other variations thereof are intended to cover a non-exclusive inclusion, so that a process, a method, an article, or a device including a series of elements not only includes those elements, but also includes other elements that are not explicitly listed, or also includes inherent elements of the process, the method, the article, or the device. In the case that there are no more restrictions, an element limited by the statement includes a . . . does not exclude the presence of additional identical elements in the process, the method, the article, or the device that includes the element.
