Description

Technical Field

[0001] The utility model relates to the technical field of thermal transfer equipment, in particular to a portable heat press. Background Art

[0002] With the growing demand for personalization, thermal transfer technology has become an important means of personalization widely used in various materials. As the core equipment for thermal transfer, the heat press machine transfers the pattern from the transfer paper to various substrates through the heating element, adding a unique visual appeal to the product.

[0003] However, the design of traditional flat heat presses usually only considers the needs of flat transfer. When faced with printing materials with arcs, curved surfaces or other non-planar structures, the limitations of this traditional design become very obvious. Since the surface shape of the heat pressing surface does not match that of the printing material, thermal transfer cannot be completed.

[0004] To solve this problem, some manufacturers have launched heat presses specifically for curved or curved materials, whose heat pressing surfaces are designed to match the printing materials of specific shapes. However, although this approach can solve the demand for non-planar thermal transfer, it also increases the economic burden of users, who need to purchase different heat presses for printing materials of different shapes. In addition, since the use scenarios of curved or curved heat presses are relatively limited, their utilization rate is often low, resulting in a waste of resources. Summary of the invention

[0005] The purpose of this patent is to overcome the shortcomings of the existing technology and design a heat press that can meet the needs of flat transfer and adapt to arc or curved transfer.

[0006] The technical solutions adopted in this application are as follows:

[0007] The portable heat press comprises: a body and a heat plate, wherein the upper end of the body is provided with a portable handheld part, the heat plate is arranged at the lower part of the body, and the lower end thereof is provided with a pressing surface and a curved pressing part, wherein the curved pressing part is defined by a concave part at the lower end of the heat plate; wherein the curved pressing part is arranged at one end of the heat plate in the direction of forward and backward deflection of the user's wrist when the heat press is used.

[0008] Compared with the prior art, the hot press of the present application adds a concave curved pressing part on the hot plate, and the part is arranged at one end of the hot plate, which has the following technical effects:

[0009] Dual thermal transfer function: By cleverly designing a concave curved pressing part on the heat plate, the heat press not only supports traditional flat thermal transfer, but also meets the transfer needs for curved or arc surfaces, thus significantly enhancing the versatility and practicality of the equipment.

[0010] Optimize user experience: The design position of the curved pressing part takes into account the wrist movement of the user when using the heat press. It is arranged at the end where the wrist naturally deflects when the user operates the heat press. This helps to reduce wrist fatigue caused by long-term operation and makes the operation more ergonomic.

[0011] Small impact on flat thermal transfer operation: Although the curved surface pressing part is added, it is set at one end of the hot plate, so when performing flat thermal transfer, the impact of this design on the operation is minimized. Users can choose to use the flat or curved surface pressing part as needed without interfering with each other.

[0012] Economy and utilization rate: By integrating the flat and curved surface thermal transfer functions into one device, the heat press machine of this application is not only highly economical, but also improves the overall utilization rate and meets the diverse transfer needs of the market.

[0013] In summary, by setting the curved pressing portion at one end of the hot plate, the hot press machine of the present application successfully achieves the expansion of functions and the improvement of user experience.

[0014] Furthermore, the position of the body corresponding to the curved surface pressing portion is concave. Using the above solution, the product structure is more compact.

[0015] Furthermore, the curved pressing part is arranged at the rear end of the direction in which the user's wrist flips forward and backward when the hot plate is used. The curved pressing part is arranged at the rear of the hot plate. This design can not only minimize the impact on the daily use of the pressing surface, ensuring that there is almost no interference during conventional flat thermal transfer, but also take into account the overall appearance of the equipment. Through this design, the functionality and aesthetics of the heat press are well balanced, providing users with a smoother and more efficient working experience.

[0016] Furthermore, at least a power supply line indirectly connected to the hot plate is arranged at the rear of the body and located above the curved surface pressing part. The power supply line is arranged at the rear side of the body and located above the curved surface pressing part. Such a layout is convenient for power connection. Since the curved surface pressing part is cleverly designed at the rear of the hot plate, such a location selection has little impact on the daily use and overall appearance of the product.

[0017] Further, the body is provided with an escape zone extending through the left and right sides, and the top wall of the escape zone and the upper end surface of the body are configured to form at least a part of the portable handheld portion;

[0018] Alternatively, one end of the portable handheld part is open, and a relief area running through the left and right sides of the body is arranged at the lower side of the portable handheld part, and the top wall of the relief area and the upper end surface of the body form at least a part of the portable handheld part.

[0019] Furthermore, at least the upper end surface of the body is provided with an arc surface extending along the direction of the user's wrist turning forward and backward. The above structure is convenient for users to use and improves the operating feel.

[0020] Furthermore, the curved surface pressing part is integrally formed on the hot plate.

[0021] Furthermore, the curved pressing portion extends along the front end direction of the hot plate and intersects with the pressing surface at an angle, so that the vertex of the outer end of the curved pressing portion is higher than the intersection point of its inner end with the pressing surface.

[0022] Furthermore, the curved pressing parts have the same curvature. The curved pressing parts adopt a uniform curvature design, which ensures close contact during the thermal transfer process. At the same time, its smooth curve makes the movement smoother and reduces the operating resistance. In addition, the use of curved pressing parts with the same curvature also simplifies the processing and manufacturing process, improves production efficiency, and brings convenience to manufacturers.

[0023] Another design of the hot plate of the present application includes a first hot plate portion and a second hot plate portion, wherein the first hot plate portion is provided with a pressing surface at the lower end, and the second hot plate portion is provided with at least a curved pressing portion, wherein the curved pressing portion is defined by a concave portion of the second hot plate portion;

[0024] Regarding the heating of the first hot plate portion and the second hot plate portion, the heating can be configured and controlled by respective heating elements, and the control circuit is configured with a control device for starting and shutting down the heating state of the first hot plate portion and the second hot plate portion. In other embodiments, the first hot plate portion and the second hot plate portion are controlled by the same heating element. The first hot plate portion and the second hot plate portion adopt a split structure, which is convenient for separate processing and manufacturing, and can also be controlled by partitions according to needs.
