Description

Technical Field

[0001] The utility model specifically relates to an ice-sensing razor head and a razor. Background Art

[0002] A razor, also known as a shaver, is a tool for shaving beards. Some users have thick beards and will feel pain when shaving. When using a razor in winter, the ice-sensing of the cutting component contacting the user's facial skin is relatively strong, bringing discomfort to the user and greatly reducing the user experience. While in summer, when an electric razor is working, the blades in the cutting component rotate and rub relatively at high speed, generating a large amount of heat between the blades, causing the temperature of the cutting unit to rise. When the skin contacts the cutting unit, this high temperature will cause discomfort to the skin.

[0003] For example, Chinese Patent (Publication No. CN215968895U) discloses a manual razor with refrigeration and heating functions, including a handle and a knife holder connected to each other. The knife holder is equipped with blades, and the handle is provided with a heat transfer structure for heating or refrigeration. The heat transfer structure and the blades are thermally conductively connected to each other, so that the temperature of the blades for shaving changes with the change of the temperature of the heat transfer structure. Among them, the heat transfer structure includes a heating body, a heating body, and a heat conduction component connected to the blade. Both the heating body and the refrigerating body are thermally conductively connected to the heat conduction component. This manual razor realizes the temperature increase and decrease of the blade by setting two components, namely the heating body and the refrigerating body, which makes the internal structure complex and increases the processing cost. Moreover, this patent improves the user experience by changing the temperature of the blade. However, the actual contact area of the blade is small, so its influence on temperature is not significant and it is not easy to change the user experience.

[0004] At the same time, the structure of the temperature control component is relatively complex, which will affect the internal structure setting of the razor, and further increase the production cost. Therefore, it is necessary to develop an ice-sensing razor with a simple internal structure and low cost. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an ice-sensing razor head and a razor.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0016] An installation groove is provided in the base. An opening is provided at the bottom of the installation groove. The width of the opening is smaller than the width of the installation groove. The temperature adjustment member and the heat conductor are sequentially arranged in the installation groove. The heat dissipation member is fixedly arranged at the lower end of the installation groove, and part of it extends into the installation groove through the opening and contacts the bottom of the temperature adjustment member. The three are fixedly connected by a locking member.

[0017] The heat dissipation member extends circumferentially outward to form a fixing portion, and the fixing portion is fixedly connected to the base.

[0018] There are three cutting components, and a gap through which the heat conductor can pass is provided at the connection of the three cutting components.

[0019] A partition is provided on the base. A through hole for restricting the temperature adjustment component is provided on the partition. The temperature adjustment member and the heat conductor of the temperature adjustment component are sequentially arranged in the through hole. The heat conductor extends circumferentially outward to form a limit fit with the through hole. The diameter of the heat dissipation member is larger than the diameter of the through hole.

[0022] Advantages of the present utility model: In this application, a gap is provided between adjacent cutting components, and the temperature adjustment component is arranged inside the base of the cutter head. Then, through the cooperation of the two, the temperature adjustment component contacts the skin through the gap. Each cutting component is adjacent to the temperature adjustment component, which facilitates contact with the human skin when the shaving device is working and effectively reduces the thermal or cold sensation of the human skin. At the same time, the integrated design of the temperature adjustment component is simpler during production and assembly. Only by reserving corresponding installation positions on the installation surface of the base of a conventional razor can the installation of the temperature adjustment component be achieved, without adding additional parts or redesigning other parts, greatly reducing the production cost.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0030] It should be noted that all directional indications (such as up, down, left, right, front, back... in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0031] Please refer to Figure 1 , Figure 1It is a schematic three-dimensional structure diagram of the electric shaver provided in Embodiment 1. Moreover, the top cover and the base of the shaver head are shown in an exploded view, and the top cover and the base can be mutually matched. The matching method can adopt magnetic attraction, snap fit, interference fit, etc. to realize the detachable connection between the two, which is convenient for cleaning the hair formed by internal cutting.

[0032] Please refer to Figure 2 , Figure 2 It is an exploded view of the temperature adjustment component and the base provided in Embodiment 1.

[0033] The temperature-sensitive shaver head is composed of a top cover and a base. The top cover 100 is provided with a plurality of cutting components 600. In this embodiment, there are two cutting components 600, and there is a gap 110 through which the temperature conductor 410 can pass between the two cutting components 600.

[0034] The cutting component 600 is installed on the top cover 100, and the top cover 100 is used to support the cutting component. The cutting component is connected to the transmission component 500 on the base, and the transmission component 500 is used to drive the cutting component to shave or cut hair.

[0035] The base 200 is internally provided with a plurality of transmission components 500 that form a transmission fit with the cutting components 600 and a temperature adjustment component 400 arranged between the transmission components 500. That is, the transmission component 500 is installed in the base 200, and the base 200 is used to protect the transmission component 500.

[0036] The top cover 100 is installed on the base 200 to support the top cover 100 through the base 200. The top cover 100 has a skin-contact area, which includes the entire gap 110, that is, it is composed of the temperature adjustment component passing through the gap. When shaving or cutting hair, the skin-contact area on the top cover 100 can contact the user's skin. The temperature adjustment component 400 is used to adjust the temperature of the skin-contact area, which can be refrigeration or heating, so as to improve the user experience when shaving or cutting hair.

[0037] The base is internally provided with an installation surface, which is used to divide the base into two isolated upper and lower spaces. The upper space is used to collect the cut hair, and the lower space is used to place the gears or heat sinks of the transmission components.

[0038] The temperature adjustment component 400 includes:

[0039] A temperature conductor 410, the upper end of which extends upward and contacts the skin through the gap 110;

[0040] A heat sink 430, and the heat sink 430 is fixedly connected to the temperature conductor 410, and an installation gap for fixing the temperature adjustment part 420 is formed between the two;

[0041] The temperature regulating component 420 is fixedly arranged in the installation gap. The upper surface of the temperature regulating component 420 is in close contact with the lower surface of the heat conducting device 410, and the lower surface of the temperature regulating component 420 is in close contact with the upper surface of the heat dissipating component 430. Moreover, the heat conducting device 410, the temperature regulating component 420 and the heat dissipating component 430 are fixed into an integral structure by a locking component 440.

[0042] The temperature regulating component 420 is installed on the heat dissipating component 430, and the heat dissipating component 430 dissipates heat from the temperature regulating component to ensure the good and normal operation of the temperature regulating component. The heat dissipating component is arranged in the base to support and protect the heat dissipating component through the base of the housing 13, and it can prevent users from directly contacting the heat dissipating component, thus affecting the user experience.

[0043] Meanwhile, in this application, the entire temperature regulating assembly is made into an integral body and fixed in the base. It can be fixedly connected to the installation surface of the base through the heat dissipating component, or fixed by the cooperation of the heat conducting device and the heat dissipating component, that is, the heat conducting component and the heat dissipating component are clamped on both sides of the installation surface to achieve fixed connection.

[0044] The base of the razor head is fixedly installed on the body 300 to drive the razor head to work through the body 300. In Embodiment 1, the base is directly snap-connected to the body to achieve the fixed connection between the two, while the top cover of the razor head and the base are connected by a buckle to achieve the detachable connection between the two.

[0045] When the user has thick beard, it is easy to pull the beard during shaving, causing obvious pain. When the user has oily skin or sensitive skin, it is easy to produce a sticky and uncomfortable feeling during shaving. At this time, the refrigeration function of the razor can be turned on, and the cold energy on the contact surface is transmitted to the skin surface of the user's shaving area, bringing an ice-cool shaving experience to the user, reducing the pain of the user's skin, as well as reducing the sticky and uncomfortable feeling, and bringing a good shaving experience to the user. When the user uses the razor in cold winter, the heating function can be turned on, and the heat energy on the contact surface is transmitted to the skin surface of the user's shaving area. The warm feeling can bring a good shaving experience to the user, and the heat can better soften the beard, open the pores, and achieve a better shaving effect.

[0046] The temperature regulating component 420 can be a semiconductor. By using the Peltier effect of the semiconductor, the effects of refrigeration and heating can be achieved through one component, simplifying the internal structure of the razor and reducing the cost. The cold end face and the hot end face are respectively arranged on the upper and lower surfaces of the temperature regulating component 420. In the refrigeration mode, the upper surface of the temperature regulating component 420 is the cold end face, and the lower surface is the hot end face; in the heating mode, the upper surface of the temperature regulating component 420 is the hot end face, and the lower surface is the cold end face. In some other embodiments, the temperature regulating component 420 can also be a heating wire, ceramics, a thermistor (PTC) or a cermet heating element (MCH) and other devices with similar temperature regulating functions.

[0047] The heat conductor 410 includes a heat-conducting substrate 411 and a heat-conducting plate 412 disposed perpendicular to the heat-conducting substrate 411. The heat conductor 410 is made of a material such as metal that is easy to conduct heat. The heat-conducting plate is in a straight shape and is just located between two cutting components, separating the two cutting components. The heat-conducting substrate is integrally formed with the heat-conducting plate, so that the heat conduction efficiency between the two is higher, and it is easier to conduct the temperature to the top end of the heat-conducting plate.

[0048] An installation groove 220 is provided in the base 200. An opening 222 is provided at the bottom of the installation groove 220. The width of the opening 222 is smaller than the width of the installation groove 220. The temperature control member 420 and the heat conductor 410 are sequentially disposed in the installation groove 220. The heat dissipation member 430 is fixedly disposed at the lower end of the installation groove 220, and part of it extends into the installation groove 220 through the opening 222 and contacts the bottom of the temperature control member 420, and the three are fixedly connected by a locking member 440.

[0049] The temperature control member 420 is disposed in the installation groove and supported by it. At the same time, the heat conductor is pressed on the upper side of the temperature control member, while the heat dissipation member is disposed on the lower side of the installation groove, and its upper end is slightly convex. Preferably, the convexity is consistent with the wall thickness at the opening, so that it can contact the temperature control member, and then transfer the heat through the heat dissipation member. Moreover, the heat dissipation member and the heat conductor are fixed together by the locking member 440, so that the entire temperature control assembly is fixed in the installation groove.

[0050] Preferably, a heat-conducting adhesive is coated on the surfaces of the temperature control member that are respectively connected to the heat conductor, so that the heat conduction efficiency is higher.

[0051] Furthermore, in order to achieve the fixing reliability of the temperature control assembly, a fixing portion 431 can be formed by extending outward in the circumferential direction of the heat dissipation member 430. The fixing portion 431 is fixedly connected to the base 200. The heat dissipation member and the installation surface of the base are fixedly connected by screws to ensure the connection reliability between the two.

[0052] Refer to Figure 3 , Figure 3 which is a three-dimensional structural schematic diagram of the razor head provided in Embodiment 2. And the top cover and the base are shown in an exploded view, and the top cover and the base can cooperate with each other. The cooperation method can adopt magnetic attraction, snap fit, interference fit, etc. to realize the detachable connection between the two, which is convenient for cleaning the hair formed by internal cutting.

[0053] Please refer to Figure 4 , Figure 4 which is an exploded view of the temperature control assembly and the base provided in Embodiment 2.

[0054] In this embodiment, there are three cutting components 600, and a gap 110 through which the temperature guide 410 can pass is provided at the connection of the three cutting components 600. That is, the three cutting components are distributed around the gap, so that when the temperature adjustment component passes through the gap, a temperature adjustment component is provided between any two adjacent cutting components.

[0055] See Figure 4 , a partition 210 is provided on the base, and a through hole 230 for restricting the temperature adjustment component 400 is provided on the partition 210. The temperature adjustment member 420 and the temperature guide 410 of the temperature adjustment component 400 are sequentially arranged in the through hole 230. The temperature guide 410 extends circumferentially outward to form a limiting fit with the through hole 230. The diameter of the heat dissipation member 430 is larger than the diameter of the through hole 230, and the heat dissipation member 430 is placed on the other side of the partition 210 and is fixedly connected to the temperature guide 410 through a locking member 440.

[0056] As Figure 5 shown, the upper end of the through hole is a non-standard circle. As shown in this embodiment, a plurality of equally spaced positioning grooves 233 are provided in the circumferential direction. As Figure 6 shown, the temperature guide includes a temperature guide substrate 411 and a temperature guide plate 412 arranged in an approximate triangle. The three sides of the temperature guide plate are arranged in an arc shape, so as to better fit the outer contour of the cutting component. And the three end corners of the temperature guide plate slightly extend out of the temperature guide substrate to form a limiting fit with the positioning groove.

[0057] At the same time, a step 231 is provided in the through hole. The temperature guide is supported by this step. The center of the step is an installation hole 232 for the temperature adjustment member, and its size is adapted to the diameter of the temperature adjustment member. The temperature adjustment member is placed in this installation hole, and its bottom is supported by the heat dissipation member. The diameter of the heat dissipation member is larger than the diameter of this installation hole. Thus, when the three are fixedly connected, the entire temperature adjustment component can be fixed to the partition as a whole.

[0058] The periphery of the heat dissipation member 430 extends upward to form a side wall 432. Part of the temperature adjustment member 420 is placed in the cavity formed by the side wall. The design of the side wall further wraps the entire temperature adjustment member to prevent the temperature adjustment member from being exposed.

[0059] The present invention also provides a razor, which includes a body 300. The body 300 is provided with the above-mentioned ice-sensing razor head. This ice-sensing razor head can adopt the razor head with double cutting components provided in Embodiment 1 or the razor head with three cutting components provided in Embodiment 2.

[0060] The embodiments should not be regarded as limiting the present invention, but any improvement based on the spirit of the present invention should be within the protection scope of the present invention.
