DETAILED DESCRIPTION OF EMBODIMENTS

The technical solutions of the embodiments of this present invention will be described clearly and completely with reference to the accompanying drawings. The described embodiments represent only a portion of the present invention, not the entirety. Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort fall within the scope of protection of this present invention.

Please refer to FIGS. 1 to 6, the present present invention discloses a reusable hard wax heating machine, comprising a housing 1, a wax container 2, a heating plate 3, and a roller 4, the wax container 2 is fixedly installed within the housing 1, with a heating plate 3 mounted on its outer surface. The upper end of the housing 1 is provided with an opening 11, and the corresponding upper end of the wax container 2 is equipped with a wax outlet 21 aligned with the opening 11.

In operation, the wax container (2) is filled with hard wax. The heating plate (3) generates heat to gradually melt the hard wax within the wax container (2) until it reaches a fluid state. The molten wax flows from the wax outlet (21) and adheres to the roller (4). Users can hold the housing (1) and roll the roller (4) back and forth over the skin area to be treated, evenly applying the hard wax to the skin surface. Since hard wax solidifies at room temperature, the molten wax begins to cool and harden immediately upon leaving the roller (4) and adhering to the skin. Once the hard wax has fully hardened, hair removal can be performed. To replenish the wax supply in the wax container (2), the shaft pin (5) is removed from the insertion hole (12), exposing the wax outlet (21) on the wax container (2) for easy refilling-a simple process.

Compared to existing technologies, the beneficial effects of this present invention include:

Unlike traditional cartridge wax heater systems that rely on soft wax with waxing paper and require loading into disposable plastic containers due to the wax's fluidity for replacement. This present invention allows the use of hard wax without the need for waxing paper, and its solid-state hardening at room temperature eliminates the requirement for plastic containers during refilling, resulting in lower usage costs and enhanced efficiency and environmental friendliness. Compared to existing hard wax heaters, which are bulky and require professional operators, the present invention features a compact and portable design. Additionally, the roller 4 applies a smaller amount of wax, allowing users to adjust the number of back-and-forth rolls based on their needs, facilitating easy control of wax usage, and offering a safer and more efficient experience.

It should be noted that this present invention pertains to the technical fields of beauty tools and human hair removal, applicable to hair removal needs across various body parts such as arms, legs, and underarms. In the beauty industry, this present invention provides an efficient and convenient hair removal tool and method, which can also be extended to the personal care field to meet consumers' needs for self-image management. Additionally, in the medical aesthetics field, it can serve as an auxiliary tool for specific hair removal treatments.

In this present invention, the detachable installation of the shaft pin (5) in the insertion hole (12) can be achieved through various methods, such as threaded connection, magnetic attachment, or snap-fit. This embodiment adopts a snap-fit structure. Specifically, as shown in FIGS. 2-4, the inner surface of the insertion hole (12) is provided with a limiting slot (121), the side of the limiting slot (121) near the outer surface of the housing (1) is equipped with an arc-shaped chamfer (122), the shaft pin (5) is provided with a protrusion (51) designed to cooperate with the limiting slot (121), and one end of the shaft pin (5) is fitted with a handle (52). When the roller (4) is in a fixed state, the protrusion (51) engages with the limiting slot (121), securing the shaft pin (5) in a relatively fixed position. The rolling action of the roller (4) does not loosen the fixation of the shaft pin (5). When it is necessary to remove the roller (4), pulling the handle (52) outward allows the protrusion (51) to slide along the arc-shaped chamfer (122) in the direction out of the insertion hole (12) until it is fully disengaged, enabling the roller (4) to be removed from the opening (11) of the housing (1). This design is simple and offers high efficiency in assembly and disassembly.

Furthermore, since the wax outlet (21) on the wax container (2) corresponds to the opening (11) on the housing (1), the wax outlet (21) of the wax container (2) can be fixed relative to the shaft pin (5), enhancing the sealing fit of the roller (4) at the wax outlet (21) and preventing molten wax from leaking into the housing (1). Specifically, as shown in FIG. 5, connection holes (22) are provided on both sides of the wax outlet (21) of the wax container (2), corresponding to the insertion holes (12) on both sides of the housing (1).

In this embodiment of the present invention, a fixing plate (23) is mounted on the outer surface of the wax container (2) near the wax outlet (21), and a fixing slot (13) is provided on the inner surface of the housing (1). The connection between the fixing plate (23) and the fixing slot (13) securely mounts the wax container (2) inside the housing (1), preventing the wax container (2) from shifting within the housing (1) and affecting its use.

As shown in FIGS. 1 and 2, this embodiment of the present invention further includes a control circuit board (14) within the housing (1). The control circuit board (14) is electrically connected to a temperature sensor (141), a temperature display (142), adjustment buttons (143), and a power connection plug (144). The temperature sensor (141) is fixedly mounted on the outer surface of the wax container (2), while the temperature display (142), adjustment buttons (143), and power connection plug (144) are fixedly exposed on the outer surface of the housing (1). The temperature sensor (141), fixed on the outer surface of the wax container (2), works in conjunction with the temperature display (142) to provide real-time temperature readings, allowing users to precisely monitor the wax temperature. Users can adjust the temperature via the adjustment buttons (143) according to their needs. The power connection plug (144), also exposed on the outer surface, facilitates quick power connection, providing stable electrical support for the device.

The wax container (2) in this embodiment is made of aluminum alloy material. The excellent thermal conductivity of aluminum alloy enables the heat from the heating plate (3) to transfer rapidly and evenly to the hard wax inside the wax container (2), achieving quick melting of the hard wax, reducing user wait times, and improving the operational efficiency of the wax heating machine.

Furthermore, the roller (4) in this embodiment is made of aluminum alloy material, with a plastic sleeve (41) fitted over it. When the roller (4) contacts the molten hard wax, it quickly absorbs the heat, allowing the roller (4) to warm up rapidly. During the rolling process, the heat is distributed evenly across the surface of the roller (4), maintaining the fluidity of the hard wax. This efficient heat transfer helps preserve the wax's liquidity on the roller (4) surface, enabling smoother adhesion of the hard wax to the roller (4) and improving the transfer efficiency from the wax container (2) to the skin surface. The plastic sleeve (41) fitted over the roller (4) serves as a thermal insulation layer, effectively isolating the high temperature of the aluminum alloy roller (4), preventing direct skin contact with the hot surface, reducing friction and irritation during rolling on the skin, and providing users with a more comfortable experience.

In this embodiment of the present invention, the housing (1) consists of two half-shells, with the two half-shells fixed together by ultrasonic welding. In some preferred embodiments, the width of the ends of the half-shells is greater than that of the middle. After assembly, the resulting overall shape of the housing (1) aligns with the ergonomic grip and support form of the human hand, providing users with a comfortable holding experience that conforms to ergonomic principles, enhancing the product's stability and controllability during use.

In this embodiment of the present invention, the opening (11) on the housing (1) is equipped with a detachable cover (15) (please refer to FIG. 6), which prevents debris from entering, maintains internal cleanliness of the device, ensures effective hair removal, and supports normal operation. After use, the hard wax requires a certain amount of time to naturally cool to room temperature, and covering it with the lid (15) prevents accidental contact with hot components, thereby improving safety during use.

Those skilled in the art should understand that this present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are intended to explain the principles of this present invention. Without departing from the spirit and scope of this present invention, various changes and improvements can be made, all of which fall within the scope of protection claimed by this present invention.
