In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.

In the description of the present invention, it should be understood that the terms "upper", "lower", and the like indicate orientations or positional relationships based on normal use of the product.

The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or to implicitly indicate the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the feature.

The embodiment of the utility model provides a hair trimmer of cutter head area light display combines fig. 1 to 5 to show, including cutter head 1 and fuselage 2, light guide 12, part are installed to cutter head 1 light guide 12 exposes and locates cutter head 1, install in the fuselage 2 circuit board 24 and with the light source 23 that 24 electricity of circuit board are connected, light guide 12 with the position of light source 23 corresponds the setting.

The light source 23 is preferably an LED lamp bead, and the circuit board 24 can control the light source 23 to be turned on or turned off; light guide 12 itself can carry out the light transmission, and the corresponding setting in position of light guide 12 and light source 23 means that the one end of light guide 12 is close to or adjacent setting with light source 23 to light guide 12 receives the light that sends from light source 23 smoothly, and the other end jets out after advancing light guide 12 transmission again, and the other end of light guide 12 exposes the setting on tool bit 1, in order to make things convenient for the user to look over.

The hair trimmer with the light display function of the cutter head 1 in the embodiment is characterized in that the light source 23 which needs to be electrically connected with the circuit board 24 is arranged in the machine body 2, the light guide part 12 which is used for displaying light to be checked by a user is arranged in the cutter head 1, the light of the light source 23 can be displayed through the light guide part 12 by utilizing the light guide performance of the light guide part 12, and the light of the light source 23 on the machine body 2 can be transmitted and displayed on the cutter head 1 so that the user can check the light.

Optionally, the light guide 12 is made of one of a PC material, a PMMA material, and a glass material. The PC material (polycarbonate) has low cost and good light-conducting property; PMMA (polymethyl methacrylate), which has small dispersion, is beneficial to ensuring the light color consistency of the light emitted by the light guide member 12, can reduce the color difference of light, has high transmittance, and can effectively reduce the transmission loss in the light guide member 12; the glass has low cost, good light guiding performance and difficult surface scratching.

Optionally, as shown in fig. 1 to 5, the light guide 12 has a light receiving end 121 and a light emitting end 122, the light receiving end 121 is disposed corresponding to the light source 23 to receive the light emitted from the light source 23, and the light emitting end 122 is disposed outside the cutting head 1 in an exposed manner. Light from light source 23 enters light guide 12 at light receiving end 121 and exits light emitting end 122 to be presented to a user for viewing.

Optionally, as shown in fig. 1 and fig. 5, a light expansion port 123 is connected to an edge of the light emitting end 122; set up light diffusion mouth 123 for the light that jets out from light emission end 122 can present better effect of shining after light diffusion mouth 123's refraction and reflection, promotes user experience and feels.

Optionally, as shown in fig. 2 and 5, a fixing frame 25 for fixing the position of the light source 23 is further installed in the body 2. The fixing frame 25 does not block the light from the light source 23 to the light guide 12, and a hole may be formed in the fixing frame 25 for transmitting light, or the fixing frame 25 may be made transparent.

Optionally, the fixing frame 25 is made of a PC material or a PMMA material, a part of the fixing frame 25 is exposed on the body 2, and the exposed part of the fixing frame 25 corresponds to the light guide 12 and the light source 23. The PC material (polycarbonate) has low cost and good light-guiding property; PMMA (polymethyl methacrylate, full name: polymethyl methacrylate), which has small chromatic dispersion, is advantageous to ensure the light color consistency of the light emitted from light guide 12, can reduce the chromatic aberration of light, has high transmittance, and can effectively reduce the propagation loss in light guide 12; the fixing frame 25 made of transparent material can completely wrap the light source 23 in the machine body 2, can prevent the light source 23 from being affected with damp and is not easy to be damaged by external force; the light from the light source 23 passes through the fixing frame 25 and then irradiates one end of the light guide member 12, so as to smoothly guide the light of the light guide member 12.

Optionally, as shown in fig. 1, 2 and 3, the cutter head 1 and the machine body 2 are detachably connected with each other. Because the light guide 12 of the tool bit 1 is not electrically connected with the light source 23 of the machine body 2 by using a wire, the tool bit 1 and the machine body 2 can be detachably connected with each other, so that a user can conveniently replace the tool bit 1 for use.

Optionally, as shown in fig. 1, fig. 2, and fig. 3, the cutting head 1 is provided with a protrusion 11, the body 2 is provided with a sliding groove 21 in sliding fit with the protrusion 11, and the sliding groove 21 is provided with a notch 211 for the protrusion 11 to enter and exit the sliding groove 21.

The convex block 11 is in inserted rotary connection with the sliding groove 21 through sliding fit of the convex block 11 and the sliding groove 21 and the arrangement of the notch 211, so that detachable connection between the cutter head 1 and the machine body 2 is realized; the number of the convex blocks 11 is two, the two convex blocks 11 are symmetrically arranged at intervals, and the number of the sliding grooves 21 corresponds to that of the convex blocks 11, so that the cutter head 1 and the machine body 2 are firmly connected; the notch 211 is arranged on the upper side wall of the middle position of the sliding chute 21, when the projection 11 moves to the position corresponding to the notch 211, the cutter head 1 can move upwards to be separated from the machine body 2, so that the function that the cutter head 1 and the machine body 2 can be mutually detached is realized, and the cutter head 1 is convenient to replace; the length direction of spout 21 is located the horizontal plane, and if lug 11 of tool bit 1 changes into spout 21 from breach 211 after forward rotation 90 makes leaded light 12 aim at light source 23, has light to send from leaded light 12 during the start, lug 11 of tool bit 1 changes into spout 21 from breach 211 after 90 leaded light 12 of reverse rotation and the light source 23 position do not correspond, does not have light to send from leaded light 12 during the start, consequently still can be used to detect whether the mounted position is accurate.

Optionally, as shown in fig. 1, 2, and 3, the sliding groove 21 is provided with a damping rib 22 for limiting the movement of the protrusion 11. The distance between the damping rib 22 and the end of the sliding groove 21 is close to the width of the bump 11, so as to ensure that the mutual position of the cutter head 1 and the machine body 2 is stable through the limitation of the damping rib 22.

Optionally, as shown in fig. 1, fig. 2, and fig. 3, transition slopes 111 are provided on both sides of the bump 11. The two sides of the protruding block 11 in the width direction are provided with transition slopes 111 to facilitate the protruding block 11 to pass through the damping rib 22 when moving, so that the cutter head 1 can rotate relative to the machine body 2 under the action of a certain external force.

Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the disclosure, and these changes and modifications are intended to fall within the scope of the disclosure.
