Description

Technical Field

[0001] The utility model belongs to the technical field of combs, in particular to an electric heating comb. Background Art

[0002] An electric comb is a household appliance that can be used to dry wet hair, straighten hair, and style curls. It primarily consists of a heating element, a metal comb head with excellent thermal conductivity, heat-insulating, burn-resistant teeth, and a heat-resistant, well-insulated handle.

[0003] For example, Chinese patent publication CN205106714U discloses an electric straightening comb comprising a heating plate with at least one row of heat-conducting teeth. The comb also includes at least one row of anti-scalding teeth that match the heat-conducting teeth, with each row of anti-scalding teeth detachably attached to the other row of heat-conducting teeth. The comb can be used for combing, straightening, and perming hair.

[0004] In the technical solution of the aforementioned patent document, the anti-scald comb teeth are made of a non-thermal conductive material, typically plastic. When the electric straightening comb is heating, the heating plate and the heat-conducting comb teeth reach high temperatures, causing the anti-scald comb teeth, which are placed over the heat-conducting comb teeth, to deform due to the high temperature. When combing hair, the heat-deformed anti-scald comb teeth can easily detach from the heat-conducting comb teeth, exposing them to the outside world and causing burns or scratches on the head, compromising user safety. Utility Model Content

[0005] The utility model aims to provide an electric heating comb to solve the problem that the anti-scalding comb teeth of the existing electric heating straight hair combs are easily deformed and separated from the heat-conducting comb teeth under high temperature, causing the heat-conducting comb teeth to burn or scratch the head.

[0006] To achieve the above-mentioned purpose, an embodiment of the present invention provides an electric heating comb, comprising heat-conducting comb teeth and anti-scalding comb teeth, wherein the anti-scalding comb teeth are detachably mounted on the heat-conducting comb teeth, and the anti-scalding comb teeth include heat-insulating comb teeth, which are hollow in structure and form two brackets connected to the main body of the anti-scalding comb teeth, and the heat-insulating comb teeth are sleeved on the outside of the heat-conducting comb teeth; a first groove is provided on one side of the heat-conducting comb teeth, and the first groove extends to the top side of the heat-conducting comb teeth, a first rib extends from the inner top of the heat-insulating comb teeth, and a second rib extends from the inner side of the bracket, and the first rib and the second rib are inserted into the first groove, so that the anti-scalding comb teeth are limited on the outside of the heat-conducting comb teeth.

[0007] Furthermore, the width of the second rib is smaller than the width of the first rib, so that the first rib and the second rib form an L-shaped structure.

[0008] Furthermore, at least one side of the top end of the first groove extends outwardly to form a step position, and the step position forms a step groove on the top side of the first groove, and the first rib is tightly matched with the step groove.

[0009] Furthermore, both sides of the top of the first groove extend outwards to form the step positions, and the step groove is formed between the two step positions.

[0010] Furthermore, at least one side of the top end of the heat-conducting comb teeth is provided with a cutout, and the inner top of the heat-insulating comb teeth is also provided with a protrusion that cooperates with the cutout.

[0011] Furthermore, cutouts are provided on both sides of the top end of the heat-conducting comb teeth.

[0012] Furthermore, at least one side of the heat-conducting comb tooth is provided with a second groove, and the heat-insulating comb tooth is provided with a rib that cooperates with the second groove; the upper end of the rib is connected to the top side of the heat-insulating comb tooth, and the lower end of the rib is connected to the main body of the anti-scalding comb tooth.

[0013] Furthermore, the second grooves are provided on both sides of the heat-conducting comb teeth; and the heat-insulating comb teeth are provided with two ribs, which cooperate with the corresponding second grooves.

[0014] The above one or more technical solutions of the electric hot comb provided by the embodiment of the present invention have at least the following technical effects:

[0015] When the user uses an electric comb to comb their hair, the heat-conducting comb teeth are in a high-temperature state due to operation, and the heat-insulating comb teeth on the outside of the heat-conducting comb teeth are easily deformed due to the high temperature. However, the first rib on the inner top of the heat-insulating comb teeth and the second rib on the bracket are inserted into the first groove of the heat-conducting comb teeth, which increases the contact area and force strength between the heat-insulating comb teeth and the heat-conducting comb teeth, so that the heat-insulating comb teeth will not fall off the outside of the heat-conducting comb teeth even if they are deformed, thereby avoiding the heat-conducting comb teeth from directly contacting the user's head and scalding or scratching the user, thereby improving safety.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0030] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0031] In one embodiment of the electric hot comb of the present invention, please refer to Figures 1 to 8 The electric heating comb includes heat-conducting comb teeth 10 and anti-scalding comb teeth 20. The anti-scalding comb teeth 20 are detachably mounted on the heat-conducting comb teeth 10. The anti-scalding comb teeth 20 include heat-insulating comb teeth 21. The heat-insulating comb teeth 21 are hollow in structure and form two brackets 22 connected to the main body of the anti-scalding comb teeth 20. The heat-insulating comb teeth 21 are sleeved on the outside of the heat-conducting comb teeth 10. A first groove 11 is provided on one side of the heat-conducting comb teeth 10, and the first groove 11 extends to the top side of the heat-conducting comb teeth 10. A first rib 23 extends from the inner top of the heat-insulating comb teeth 21, and a second rib 24 extends from the inner side of a bracket 22. The first rib 23 and the second rib 24 are inserted into the first groove 11, so that the anti-scalding comb teeth 20 are limited to the outside of the heat-conducting comb teeth 10. Specifically, when a user uses an electric comb to comb their hair, the heat-conducting comb teeth 10 are in a high-temperature state due to operation, and the heat-insulating comb teeth 20 on the outside of the heat-conducting comb teeth 10 are easily deformed due to high temperature. However, the first rib 23 on the inner top of the heat-insulating comb teeth 21 and the second rib 24 of the bracket are inserted into the first groove 11 of the heat-conducting comb teeth, which increases the contact area and force strength between the heat-insulating comb teeth 21 and the heat-conducting comb teeth 10. Even if the heat-insulating comb teeth 21 are deformed, they will not separate from the outside of the heat-conducting comb teeth 10, thereby avoiding the heat-conducting comb teeth 10 from directly contacting the user's head and scalding or scratching the user, thereby improving safety.

[0032] Furthermore, the width of the second rib 24 is smaller than the width of the first rib 23, so that the first rib 23 and the second rib 24 form an L-shaped structure. Specifically, the width of the second rib 24 is smaller than the width of the first rib 23, which reduces the molding material of the second rib 24 of the insulation comb teeth and saves costs.

[0033] Furthermore, a step 12 extends outward from at least one side of the top of the first groove 11. The step 12 forms a stepped groove 13 on the top side of the first groove 11, and the first rib 23 fits tightly with the stepped groove 13. Specifically, the first rib 23 fits tightly with the stepped groove 13 at the top of the first groove. The step 12 can withstand a certain load, thereby improving the connection strength between the first rib 23 and the first groove 11 and enhancing stability.

[0034] Furthermore, steps 12 extend outward on both sides of the top of the first groove 11, and a step groove 13 is formed between the two steps 12. Specifically, the steps 12 are provided on both sides of the top of the first groove 11 to further increase the load strength and enhance the firmness of the connection between the first rib 23 and the first groove 11.

[0035] Furthermore, a notch 14 is provided on at least one side of the top of the thermally conductive comb teeth 10, and a protrusion 25 extends from the inner top of the thermally insulating comb teeth 21 to mate with the notch 14. Specifically, the provision of the notch 14 and the protrusion 25 increases the contact surface between the thermally insulating comb teeth 21 and the thermally conductive comb teeth 10, preventing the top of the thermally insulating comb teeth 21 from completely separating from the thermally conductive comb teeth 10 after deformation, thereby reducing the risk of burns.

[0036] Furthermore, both sides of the top of the heat-conducting comb teeth 21 are provided with cutouts 14. Specifically, both sides of the top of the heat-insulating comb teeth 21 are provided with protrusions 25 that cooperate with the cutouts 14, which increases the protection area between the heat-insulating comb teeth 21 and the user, further reducing the risk of burns.

[0037] Furthermore, at least one side of the heat-conducting comb teeth 10 is provided with a second groove 15, and the heat-insulating comb teeth 21 are provided with ribs 26 that mate with the second grooves 15. The upper ends of the ribs 26 are connected to the top sides of the heat-insulating comb teeth 21, while the lower ends of the ribs 26 are connected to the main body of the anti-scalding comb teeth 20. Specifically, the second grooves 15 of the heat-conducting comb teeth 10 constrain the ribs 26 of the heat-insulating comb teeth 21, while the other ends of the ribs 26 are connected to the main body of the anti-scalding comb teeth 20, preventing the ribs 26 from disengaging from the second grooves 15, thereby preventing the heat-insulating comb teeth 21 from being disengaged from the ribs 26.

[0038] Furthermore, second grooves 15 are provided on both sides of the thermally conductive comb teeth 10. The thermally insulating comb teeth 21 are provided with two ribs 26 that engage with the corresponding second grooves 15. Specifically, the two ribs 26 securely fit the thermally insulating comb teeth 21 onto the outer sides of the thermally conductive comb teeth 10, preventing the thermally insulating comb teeth 21 from separating from the thermally conductive comb teeth 10.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
