[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Furthermore, the terms "first," "second," "third," and "fourth," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] See Figures 1-6 This utility model discloses a tea roasting machine, including a box 1 with a roasting space 101. At least one side of the roasting space 101 is provided with an electric heating film 2, which faces the roasting space 101 to heat the roasting space 101. One side of the box 1 is also provided with an opening 102, and the opening 102 is provided with a cabinet door 103 for opening the roasting space 101.

[0029] It is understandable that a function button 8 for controlling the operation of the heating film 2 can be provided on the cabinet 1. When in use, the tea leaves can be placed into the roasting space 101 by opening the cabinet door 103, and then the heating film 2 can be controlled by the function button 8 to heat the roasting space 101. At this time, the heat generated by the heating film 2 will fill the entire roasting space 101, thereby roasting the tea leaves. In this embodiment, since the heating film 2 directly heats the entire roasting space 101, it can fully awaken the aroma components inside the tea leaves. The tea roasting machine of this utility model has a simple structure, can effectively improve the brewing taste of tea, and is suitable for home or small commercial settings.

[0030] Furthermore, the heating film 2 is a graphene heating film. In this embodiment, by placing the graphene heating film at the bottom of the tea roasting machine, the high thermal conductivity of the graphene heating film allows for rapid conversion of electrical energy into heat energy, enabling the tea roasting machine to heat up quickly and shortening the preheating time. Moreover, the graphene heating film can achieve uniform heating, so when the graphene heating film faces the entire roasting space 101, it can ensure that the tea leaves in all positions within the roasting space 101 are heated evenly, improving the roasting quality.

[0031] Preferably, the area of ​​the heating film 2 is more than two-thirds of the surface area of ​​the box 1 where the heating film 2 is located, so as to ensure the heating efficiency of the entire baking space 101 and ensure that the tea leaves in all positions in the baking space 101 are heated evenly.

[0032] Specifically, the housing 1 includes a housing frame 11 and multiple heat insulation panels 12 distributed around the baking space 101. The heat insulation panels 12 are respectively embedded in the housing frame 11 to enclose the baking space 101. In this embodiment, by embedding heat insulation panels 12 on each surface of the housing 1, not only can the user's safety be ensured to avoid being burned by the temperature inside the tea roasting machine, but heat loss in the baking space 101 can also be reduced and energy consumption lowered. Preferably, the area of ​​the heat insulation panel 12 is more than two-thirds of the area of ​​the surface of the housing 1 on which the heat insulation panel 12 is located, so as to better exert the heat insulation effect.

[0033] In this embodiment, at least one heat insulation plate 12 is made of a transparent material, such as transparent glass, so that the user can observe the changes in the baking space 101, thereby intuitively observing the changes in the tea during the baking process, and making it easier for the user to accurately adjust the baking time and temperature according to the real-time status of the tea.

[0034] In one specific embodiment, the heat insulation panels 12 installed on each side of the cabinet frame 11 are all made of transparent material, such as transparent glass, and the graphene heating film or other electric heating film 2 is also made of transparent material. This not only allows the user to observe the changes in the baking space 101 from each side of the cabinet 1, but also enhances the overall aesthetics of the tea roasting machine.

[0035] Specifically, the housing frame 11 includes an upper frame 1101, a lower frame 1102, and multiple supporting structures 1103. The upper frame 1101 and the lower frame 1102 are connected by the multiple supporting structures 1103 to form the housing frame 11. Both the upper frame 1101 and the lower frame 1102 are hollow structures, allowing for the installation of heat insulation panels 12 within their hollow structures. In this embodiment, the upper frame 1101, the lower frame 1102, and the multiple supporting structures 1103 facilitate the installation of heat insulation panels 12 on various surfaces of the housing, and also facilitate the installation of heating films.

[0036] In addition, the support structure 1103 can be configured as a hollow structure to facilitate wiring within it; the upper frame 1101 and / or the lower frame 1102 can also be configured as hollow structures to facilitate wiring within them, and to facilitate the installation of the circuit board 9, the button board, and the heating film, etc. It is understood that the circuit board 9 can be installed within the upper frame 1101 or the lower frame 1102 to allow the circuit board 9 to control the operation of the heating film based on the pressed state of the function button 8.

[0037] The lower frame 1102 includes a support frame 4 for supporting the heating film 2. The heating film 2 is snapped between the support frame 4 and the inner side of the lower frame 1102, and the heat insulation plate 12 is snapped between the support frame 4 and the outer side of the lower frame 1102. In this embodiment, by providing a support frame 4 with a certain thickness and installing it between the heating film and the heat insulation plate 12, direct contact between the heating film and the heat insulation plate 12 is avoided, thus preventing heat conduction from being affected and reducing the risk of the heat insulation plate 12 being damaged due to overheating.

[0038] Among them, the support frame 4 is a hollow structure so that when the heat insulation plate 12 and the electric heating film 2 are both transparent materials, the support structure 1103 does not affect the transparency of the heat insulation plate 12 and the electric heating film 2 in the lower frame 1102, and also improves the overall aesthetics of the tea roasting machine.

[0039] Furthermore, the inner side of the housing 1 is provided with several layers of support sections, including multiple equal-height mounting platforms 6 on the support structure 1103. When using the tea roasting machine, a roasting rack can be used in conjunction with it. The mounting platforms 6 serve as the support structure 1103 for the roasting rack, while the tea leaves need to be evenly spread on the roasting rack. Because the heating film 2 maintains a certain distance from the tea leaves, this facilitates effective heat conduction. The roasting rack is designed with a perforated shape to ensure that hot air can fully contact the tea leaves from all directions to achieve uniform roasting.

[0040] Furthermore, a fan structure 3 is also provided within the lower frame 1102, with the air outlet of the fan structure 3 leading to the air inlet 1011 of the baking space 101. The air inlet of the fan structure can be located at the bottom of the lower frame 1102, while the air outlet of the baking space is located at the top of the baking space. This allows external air to enter the baking space 101 from the bottom of the lower frame under the action of the fan structure 3, and then exit from the air outlet at the top of the baking space, thereby accelerating air circulation within the baking space 101. This ensures that heat is evenly distributed around the tea leaves, allowing all parts of the tea leaves to be fully heated. Since the heating film is located at the bottom of the baking space, heat circulates from bottom to top, allowing moisture generated during the heating process to be discharged from the air outlet at the top of the baking space. This significantly improves the baking effect of the tea leaves and brings out their rich and mellow aroma.

[0041] In one embodiment of this utility model, the cabinet door 103 can be set as a heat insulation plate 12, which is hinged to the opening 102 by a hinge. The cabinet door 103 is also provided with a handle 7 to facilitate opening the roasting space 101 to put in tea leaves. In this embodiment, setting the cabinet door 103 as a heat insulation plate 12 made of transparent material not only makes it easier to observe the internal condition of the roasting space 101, but also significantly improves the overall texture and grade of the tea roasting machine.

[0042] When using this tea roasting machine, after opening the cabinet door 103 using the handle 7, spread the tea leaves flat on the roasting rack. When there are many tea leaves, multiple roasting racks can be placed. Then, use the function button 8 to set the appropriate roasting time and temperature. At this time, after receiving the instruction, the circuit board 9 will control the bottom heating film 2 to heat up. Since the heating film 2 uses graphene material, the heating film 2 can heat up quickly.

[0043] At the same time, the fan structure 3 inside the tea roasting machine starts, and external air enters the interior of the tea roasting machine through the air inlet on the bottom shell. Under the action of the fan, the hot air circulates within the roasting space 101, and the heat evenly coats the tea leaves. The roasting rack allows the tea leaves to be placed in layers, further increasing the contact area with the hot air and ensuring that the tea leaves are heated evenly. The heat insulation plate 12 can effectively prevent heat loss and maintain a stable high-temperature environment within the roasting space 101. Throughout the roasting process, the user can observe the state of the tea leaves through the heat insulation plate 12. When the preset roasting time is reached, the heating film and fan structure 3 stop working. The user can then take out the roasted tea leaves from the roasting space 101 to brew and enjoy a fragrant tea drink.

[0044] In summary, this utility model tea roasting machine, by setting an electric heating film 2 directly facing the roasting space 101 within the roasting space 101, allows tea leaves to be placed inside the roasting space 101 before brewing. The electric heating film 2 heats the tea leaves within the roasting space 101, thus fully awakening the aroma components within the tea leaves. This utility model tea roasting machine has a simple structure, enhances the brewed taste of tea, and is suitable for home or small commercial settings.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
