Description

[Technical Field]

[0001] The present invention relates to an eyelash curler. [Background technology]

[0002] The impression of the eyes can have a significant impact on the overall impression of the face. For this reason, many makeup techniques and cosmetics have been developed to make the eyes appear larger and clearer, improving the overall impression of the face. One of these is the use of eyelash curlers to make the eyes appear larger and clearer. Heated eyelash curlers can maintain the curled state for a longer period of time. The following heated eyelash curler technology has been known in the past (see Patent Document 1).

[0003] On the other hand, when you have limited time to put on makeup, such as before going to work, a heated eyelash curler with a short heating time is desirable. Also, since heated eyelash curlers are placed near the eyes, a safe product that does not get too hot is desirable. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Registered Utility Model Publication No. 3089207 Summary of the Invention [Problem to be solved by the invention]

[0005] The inventors recognized the following problems when realizing the technology of Patent Document 1. The technology of Patent Document 1 uses a heating element wrapped in an insulating material to heat the eyelashes. With this configuration, it may take a long time for the heating element to heat up. There is a need for an eyelash curler that can heat up to the appropriate temperature in a shorter time.

[0006] The present invention has been made in view of the above problems, and its object is to provide a heated eyelash curler that can be heated to an appropriate temperature in a short time. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0010] In the following, the same or equivalent components and members will be given the same symbols in each drawing, and duplicated explanations and some unimportant members will be omitted as appropriate.

[0011] Example 1 Fig. 1 is a perspective view showing an eyelash curler 100 according to an embodiment. Fig. 2 is a partially enlarged front view showing the eyelash curler 100 according to embodiment 1. The eyelash curler 100 has a frame 20, a housing 50, and a handle 10.

[0012] Frame 20 has first clamping portion 22 and second clamping portion 24. Handles 10a, 10b are rotatably supported by support shaft 12, and second clamping portion 24 slides in conjunction with the opening and closing of handles 10a, 10b, thereby opening and closing frame 20.

[0013] The first clamping portion 22 is formed in a gate shape by joining a horizontally long thin plate member 60 curved to fit the shape of the user's eyelashes and pillar members 62 supporting both ends of the plate member.

[0014] The second clamping unit 24 is also formed in a gate shape by joining a curved, horizontally elongated thin plate member 64 and a pillar member 66. The pillar member 66 of the second clamping unit slides along the pillar member 62 of the first clamping unit, opening and closing the frame 20. The second clamping unit 24 has an elastic member 30 at a position that corresponds to the first clamping unit 22 when closed. FIG. 3 is a partially enlarged perspective view of the front of the eyelash curler according to the first embodiment, viewed from above. The second clamping unit 24 has a concave mating recess 26 on the upper surface of the thin plate member 64, into which the elastic member 30 is removably fitted. The mating recess 26 is curved in accordance with the second clamping unit 24, and the elastic member 30 is similarly curved. The elastic member 30 has insulating properties and is made of silicone rubber in the first embodiment.

[0015] FIG. 4 is a cross-sectional view taken along line A-A' in FIG. 2. A heat insulating material 34 and a surface heating element 32 are stacked in this order on one of the inner wall surfaces of the fitting recess 26. When the elastic member 30 is fitted, the surface heating element 32 contacts one of the side walls 36 of the elastic member 30. The surface heating element 32 includes a surface resistor formed by coating a thin film of paint-formed carbon nanotubes on a polyimide sheet substrate, and has a thickness of 0.1 mm to 0.3 mm and a resistance value of 25 Ω to 120 Ω. The sheet substrate may be formed from PET (polyethylene terephthalate) resin. The surface heating element 32 is rectangular to match the shape of the side wall 36, covering 70 to 100% of the side wall 36. The head of the elastic member 30 protrudes from the fitting recess 26. Note that the numerical ranges described below are also ranges that have been experimentally confirmed to be convenient to use.

[0016] FIG. 5 is a partially enlarged front cross-sectional view schematically illustrating the internal structure of the eyelash curler according to the first embodiment. The surface heating element 32 is electrically connected to a secondary battery 42 via a control unit 40, allowing a voltage of 3.0 V to 24 V to be applied. The secondary battery 42 is charged via an external adapter (not shown) through a charging port 48 (described below). The secondary battery 42 has a capacity of 80 to 120 mAh and can be fully charged within two hours. For example, if the average values ​​of the battery capacity, resistance, and voltage mentioned above are taken, the secondary battery 42 can be used continuously for 30 minutes from a fully charged state. The control unit 40 cuts off the power three minutes after application.

[0017] The control unit 40 and secondary battery 42 are housed in a housing 50. A power button 46 and a charging port 48 for a USB (Universal Serial Bus) terminal are provided on the outside of the housing 50. The control unit 40 and the power button 46 are connected, and when the power button 46 is pressed, a voltage is applied to the surface heating element 32. The control unit 40 controls the voltage to the surface heating element 32 according to a setting that causes the elastic member 30 to maintain an appropriate temperature of 45°C to 55°C. The back side of the housing 50 is concave to fit the shape of the user's cheek. The housing 50 is located below the base of the gate-shaped second clamping portion 24, and there is a sufficient gap between the second clamping portion 24 and the housing 50 so that the user's field of vision is not obstructed.

[0018] The eyelash curler 100 having the above configuration is used as follows. When the power button 46 is pressed, voltage is output to the surface heating element 32 via the control unit 40, and the surface heating element 32 heats the elastic member 30. According to the inventor's operational testing, the elastic member 30 reaches 50°C in 3 to 5 seconds. The user waits for the elastic member 30 to warm up, then places the frame 20 open over one eye, inserts the eyelashes between the first clamping portion 22 and the second clamping portion 24, closes the handle 10, and clamps the eyelashes between the first clamping portion 22 and the second clamping portion 24. The user adjusts the amount of time the heat is applied depending on the part of the eyelash, and then glides the device from the root to the tip, lifting the eyelashes in the desired angle. The control unit 40 stops outputting power three minutes after the power button 46 is pressed. The elastic member 30 can be replaced by pinching and removing the portion protruding from the fitting recess 26.

[0019] The above configuration has the following effects. The surface heating element 32 generates heat efficiently and uniformly over its entire surface by electric heat and far-infrared radiation, quickly and evenly heating the elastic member 30. The surface heating element 32 has a higher far-infrared emissivity and consumes less power than a surface heating element made of metal.

[0020] (Experimental example) A comparative experiment was conducted on the temperature rise time of the eyelash curler 100 according to Example 1 and the heated eyelash curlers Conventional Products A (200), B (300), C (400), D (500), and E (600). Figure 6 shows the results of the comparison, showing the temperature rise time (700) and the temperature (800) reached by the elastic member. The initial temperature of the elastic member was 26.8°C to 28.4°C, and the weight of the elastic member used was 0.3g to 0.8g. Conventional Product A (200) has a metal plate-shaped heating element inserted inside the elastic member, while Conventional Products B (300), C (400), D (500), and E (600) have a metal coil-shaped heating element inserted in the same way.

[0021] The eyelash curler 100 reached 50°C in 4 seconds. In contrast, conventional products A to E (200, 300, 400, 500, 600) took 17 to 110 seconds to reach 45 to 52°C.

[0022] The eyelash curler 100 further has the following effects. The second clamping part 24 is shaped like a gate, with enough clearance to ensure the user's field of vision is not obstructed when clamping the eyelashes, and the position can be adjusted by looking in a mirror, making it easy to operate. It is economical because only the elastic member 30 needs to be replaced when it becomes worn out. The control unit 40 keeps the surface heating element 32 at an appropriate temperature and has an automatic stop function, making it safe to use. The first clamping part 22, second clamping part 24, and housing 50 are shaped to fit the user's eyelashes and cheeks, making it easy to operate.

[0023] Example 2 The eyelash curler 100 of the second embodiment will be described below. 7(a) is an enlarged front view of the eyelash curler according to Example 2, and (b) is an enlarged cross-sectional view taken along line B-B' in (a). A heat insulating material 34 and a surface heating element 32 are provided in this order on both inner side walls of the fitting recess 26, and the elastic member 30 is fitted into the fitting recess 26. The surface heating elements 32a and 32b are placed so as to sandwich both side walls 36a and 36b of the elastic member 30. The elastic member 30 is heated by the surface heating elements 32a and 32b on both side walls 36a and 36b, so it can be heated efficiently and quickly.

[0024] The above describes the base technology examples 1 and 2. However, the following modified technology is also available. (Variation 1) The elastic member 30 may be made of silicone rubber filled with carbon nanotubes or silicone rubber to which other conductive fillers are added, eliminating the need for the surface heating element 32, thereby reducing the manufacturing process and raw material costs.

[0025] (Variation 2) The surface heating element 32 may be a surface resistor made of a metal such as aluminum, or a surface resistor filled with carbon black, which allows for a reduction in raw material costs. [Explanation of symbols]
