In order to explain the technical solution of the present invention, the implementation of a shaver provided by the present invention will be described in detail through specific embodiments with reference to specific drawings.

Please refer to FIG. 1, a shaver provided by an embodiment of the present invention includes a main body (not shown in the figure) and a cutter head assembly (not shown in the figure) provided on the main body. The fuselage includes a metal case 10 and a control board (not shown in the figure) provided in the metal case 10. An indicator light (not shown) is provided on the control board, and the metal case 10 is provided with A light-transmitting hole 11 through which the light of the indicator light can penetrate.

In this embodiment, the casing of the fuselage is designed as a metal casing 10, and the metal casing 10 has a good feel, texture and appearance effect; moreover, the metal casing 10 has better anti-fall, compression resistance, and can better Protect the internal components and improve the quality of the shaver; at the same time, a light-transmitting hole 11 is provided in the metal casing 10 so that the light of the indicator light is emitted from the light-transmitting hole 11 to better display the current status of the shaver. In this way, not only the problem of poor texture of the plastic case in the prior art, but also the display of the indicator light in the metal case 10 is solved.

The material of the metal casing 10 may be stainless steel, aluminum alloy, titanium alloy, magnesium alloy, etc., and other metal materials may be selected according to design requirements.

Preferably, in this embodiment, the diameter of the light transmitting hole 11 ranges from 0.03 mm to 0.3 mm. The diameter of the light-transmitting hole 11 is designed in this range. The light-transmitting hole 11 is almost a tiny hole that can be just seen by the human eye. Such a tiny hole can also meet the waterproof requirement on the premise of meeting the light transmission requirement. In normal use, that is, irrespective of the situation where the shaver is completely immersed in water, it is almost impossible for external water to enter the inside of the fuselage through the tiny transparent holes 11 in this range. Therefore, the design of the transparent holes 11 meets the normal waterproof requirements . Take a step back and remove the situation that the razor is immersed in the water. Even if external water enters through the tiny transparent holes 11, the external water is also splashed in. The amount of water is extremely small and can be ignored. It will not cause any damage to the internal components of the shaver influences.

Of course, in order to pursue the high quality of the product, a transparent sealing layer (not shown in the figure) may also be provided inside the light transmitting hole 11. In this way, the light transmission effect of the light transmission holes 11 is not affected, and at the same time, the waterproof sealing performance of the shaver is further improved. Under normal use, the probability of water seepage from the light transmitting holes 11 is reduced to zero. Even under abnormal conditions, such as when the razor is completely immersed in water, due to the extremely small aperture of the light transmitting hole 11 and the sealing effect of the sealing layer, the probability of damaging internal components by water seepage through the light transmitting hole 11 is also great. reduce.

Specifically, the light transmitting holes 11 are in multiple groups. In this embodiment, there are four groups of light transmitting holes 11. Of course, in other embodiments, the light transmitting holes 11 may also be designed as a group. In this embodiment, each group of the light transmitting holes 11 includes a plurality of light transmitting holes 11. Referring to FIG. 3, a plurality of light-transmitting holes 11 are arranged in a circle. In other embodiments, the light-transmitting holes 11 may also be arranged in other shapes such as a rectangle, a triangle, or a circular ring. A plurality of groups of light-transmitting holes 11 are provided, which correspond to different groups of light-transmitting holes 11 and display different states. For example, in this embodiment, a bright light is emitted from the first group of light-transmitting holes 11 located on the upper side, that is, when the indicator light located inside the first group of light-transmitting holes 11 is on, it can indicate that the power supply is in a standby state; Two groups of light-transmitting holes 11 emit bright light, that is, when the indicator light located inside the second group of light-transmitting holes 11 is lit, it can indicate the shaving work status; from the top to the bottom, the third group of light-transmitting holes 11 emit light, that is, When the indicator light located inside the third group of light-transmitting holes 11 is on, it can indicate the charging status of the shaver ... Of course, different states can also be represented for different numbers of light-transmitting groups. For example, in the charging state, when one group of light-transmitting holes 11 emits bright light, it indicates that charging is 25% complete; when two groups of light-transmitting holes 11 emit light, it indicates that charging is 50% complete; when three groups of light-transmitting holes 11 emit light When it is used, it means that the charging is 75% complete ... In the use state, when a group of light-transmitting holes 11 emits bright light, it indicates that 25% of the power is left; when two groups of light-transmitting holes 11 emit light, it indicates that 50% of the power is left ; When the three groups of light-transmitting holes 11 emit bright light, it indicates that 75% of the power is left ... That is to say, the design of the light-transmitting hole 11 is closely related to the control mode of the control panel to the indicator light. At design time, according to the needs of the user and the function requirements of the shaver, the control situation of the control panel for different indicators is designed. Circumstances to design the light transmission hole 11.

In this embodiment, a plurality of groups of light-transmitting holes 11 are arranged in a straight line at equal intervals from top to bottom along the length direction of the fuselage. In other embodiments, a plurality of groups of light transmitting holes 11 may be arranged in a pattern shape. The pattern can be the manufacturer's LOGO, it can also be symbolic or can leave a deep pattern shape for others.

Referring to FIG. 2 and FIG. 4, a counterbore 12 is provided on the inner wall of the housing to form a light-transmitting channel, and the translucent hole 11 is provided at the bottom of the counterbore 12 and penetrates the wall of the housing. The cross-sectional area of the light-transmitting channel gradually decreases from the inside to the outside. A light-transmitting channel is provided inside the light-transmitting hole 11, so that the indicator light inside the shaver can enter the light-transmitting hole 11 through the light-transmitting channel, and because the cross-sectional area of the light-transmitting channel gradually decreases from the inside to the outside, the indicator The light sink of the lamp is concentrated to the bottom of the counterbore 12 and emitted from the light-transmitting hole 11 to enhance the brightness of the light emitted from the light-transmitting hole 11.

Since the counterbore 12 is formed on the inner wall of the housing to form the above-mentioned light-transmitting channel, the thickness d of the bottom wall 121 of the counterbore 12 is reduced. In this embodiment, the thickness d of the bottom wall 121 of the counterbore 12 is a light-transmitting hole. The thickness of the shell wall at 11 places ranges from 0.2mm to 1.5mm. Because the shell wall is thin here, the shell wall is easily deformed when processing the light-transmitting hole 11, and at the same time, the processing hole is more difficult because the aperture of the light-transmitting hole 11 is small. In order to solve the above-mentioned problem, in this embodiment, a laser is used to process the light-transmissive hole 11. During laser processing, the laser beam is highly concentrated in space and time. The lens is focused to reduce the spot diameter to the micron level to obtain the laser power density. At such a high power density, laser drilling can be performed on any metal material, and compared with other conventional drilling methods, the laser processing of the light-transmitting holes 11 has the advantages of high speed, high efficiency, and avoiding deformation of the shell wall surface. .

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
