Description

Technical Field

[0001] This utility model relates to the field of hairdressing teaching aids technology, specifically to a hairdressing teaching head model with replaceable hair. Background Technology

[0002] In the field of hairdressing education, teaching head models are indispensable practical training tools. They are mainly used to simulate the structure of the human head, allowing students to practice hairdressing skills such as washing, cutting, blow-drying, dyeing, and perming. Currently, hairdressing teaching head models on the market usually adopt a fixed structure, meaning that the scalp and hair of the head model are designed as a single, non-replaceable unit.

[0003] This traditional structure has obvious drawbacks: on the one hand, after a trainee completes a hairdressing operation (such as cutting hair short), the head mold cannot be restored to its initial state. If other hairstyles or operations need to be practiced, a completely new head mold must be replaced, which greatly increases the teaching cost. On the other hand, some head molds with replaceable hair are fixed by simple fitting or pasting, which is cumbersome and prone to misalignment, especially at the hairline position where the fit is poor, making it difficult to simulate the hair distribution of a real human head, affecting the authenticity of teaching and the effectiveness of training. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hair styling teaching head model with replaceable hair, making it convenient to replace with a new one.

Detailed Implementation

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0026] like Figure 1-6 As shown, this embodiment provides a hair styling teaching head mold with replaceable hair, including: a head mold body with a base 700 connected to its bottom, the base 700 having a connection structure connected to a support frame; a head shell 400 detachably connected to the head mold body, the position where the head shell 400 connects to the head mold body forming a hairline 401; and a scalp 500 detachably covering the head shell 400 and fitting against the outer edge of the head shell 400. The base 700 supports the entire hair styling teaching head mold, and the connection structure can be a fixing hole. The hair styling teaching head mold is mounted on the support frame through the fixing hole, allowing it to be fixed at a suitable height for the practitioner. The fixing hole is disposed within a fixing post 710, extending from the bottom of the base 700 to the interior of the fixing post 710. The top of the support frame has a fixing post, which is inserted into the fixing hole to fix the teaching head mold.

[0027] The detachable connection between the head shell 400 and the head mold body, and the detachable design between the scalp 500 and the head shell 400, allows the scalp 500 and the attached hair to be flexibly replaced according to teaching needs. After cutting their hair, students only need to replace the scalp 500 to reuse the head mold body, eliminating the need to purchase a brand new head mold and significantly reducing the investment cost of teaching equipment.

[0028] In some embodiments, the head mold body includes a front face piece 100, a back neck piece 200, and a hairline support shell 300. The front face piece 100 and the back neck piece 200 are connected along a parting line and fixed to the base 700. The hairline support shell 300 is disposed in the top space enclosed by the front face piece 100 and the back neck piece 200. The head shell piece 400 is connected to the hairline support shell 300. The front face piece 100, the back neck piece 200, and the head shell piece 400 can be assembled to form the head mold body, that is, the shape of the head mold, to imitate the human head. Specifically, the parting line of the front face piece 100 and the back neck piece 200 is distributed approximately along the middle part of the head mold body. To save material, the head mold body after the front face piece 100 and the back neck piece 200 are fastened together is hollow. Both the front face piece 100 and the back neck piece 200 are connected to the base 700 by bolts.

[0029] In some embodiments, the scalp component 500 includes an elastic soft rubber layer and simulated hair implanted in the soft rubber layer. The edge of the soft rubber layer is provided with a U-shaped flange for wrapping around the head shell component 400. The hair simulates human hair, allowing the user to practice manipulating it. The scalp component 500 is elastic and can be pulled during installation to ensure the flange secures to the edge of the head shell component 400. This makes replacing the scalp component 500 more convenient.

[0030] The head model body, through the combination structure of the front face part 100, the back neck part 200 and the hairline support shell 300, accurately positions the hairline 401. At the same time, the scalp part 500 and the hairline support shell 300 are engaged by the tenon 420 and the slot 301, and the guide part 430 and the guide groove 302 are added to ensure that the scalp part 500 can be quickly and accurately connected to the preset position during installation, so that the hairline 401 fits better and is closer to the hair growth state of the real human head, providing students with a realistic training environment and improving the teaching effect.

[0031] In some embodiments, the hairline support shell 300 and the head shell component 400 are engaged by a latch 420 and a slot 301. The latch 420 and the slot 301 are respectively fixed to the hairline support shell 300 and the head shell component 400. Specifically, the latch 420 can be fixed inside the head shell component 400, and the slot 301 can be disposed on the hairline support shell 300. When installing the head shell component 400, the latch 420 is inserted into the slot 301 to fix the head shell component 400 to the hairline support shell 300. To increase the stability of the head shell component 400, multiple latches 420 and slots 301 are provided, and their installation positions correspond one-to-one, making it easier to align all the slots 301 and latches 420 during installation.

[0032] In some embodiments, a guide 430 and a guide groove 302 for guiding the head shell 400 to the correct installation position are further provided between the head shell 400 and the hairline support shell 300.

[0033] In some embodiments, a locking lever 600 is further included. The locking lever 600 is rotatably disposed within the head mold body. A locking assembly for locking by rotation is constructed at the top of the locking lever 600 and at the contact point between the head shell 400 and the locking lever 600. A toggle button 610 is provided at the bottom of the locking lever 600, with at least a portion of the toggle button 610 extending out of the head mold body for operation. Specifically, the toggle button 610 at the bottom of the locking lever 600 extends from the front face 100. A clearance hole 101 is provided near the bottom of the front face 100, the width of which is smaller than the diameter of the toggle button 610, to ensure that the toggle button 610 extends partially but not completely. Specifically, to ensure smooth rotation of the locking lever 600, the locking lever 600 is configured to pass through the hairline support shell 300, within which a channel matching the locking lever 600 is constructed. Furthermore, a bracket supporting the toggle button 610 is provided on the base 700. The bracket includes two side-by-side support plates 720, the tops of which are inclined. Furthermore, a cover plate 110 is provided on the clearance hole 101 of the front panel 100. The cover plate 110 covers the toggle button 610 to prevent accidental activation of the toggle button 610 when the scalp panel 500 needs to be replaced.

[0034] In some embodiments, the locking assembly includes a lock body 620 fixed to the end of the locking lever 600 and a locking block 410 fixed to the head shell 400. The lock body 620 has a locking cavity 621, and a slot 301 communicating with the locking cavity 621 is provided on the top of the lock body 620. The locking block 410 is engaged in the locking cavity 621 by the slot 301 and locked after rotation. Furthermore, to ensure that it does not loosen or wobble after locking, an inclined surface is provided in the locking cavity 621. After the head shell 400 is fixed to the hairline support shell 300, the lock body 620 is engaged in the slot 301. By rotating the locking lever 600, the lock body 620 can be screwed into the locking cavity 621, which shares a bottom surface with the slot 301. An inclined surface is set at the top of the locking cavity 621. The inclined surface limits the net height of the locking cavity 621 to a state that gradually decreases from one end to the other. The lock body 620 is screwed in from the side with a larger net height and turns to the side with a smaller net height of the locking cavity 621, thereby locking the lock body 620, which in turn locks the head shell 400 and the hairline support shell 300.
