Description

Technical Field

[0001] The utility model relates to the technical field of personal care equipment, in particular to an ice-sensing cutter head assembly and an electric shaver comprising the cutter head assembly. Background Art

[0002] Razors can be categorized as manual razors and electric razors based on their shaving principles. As a shaving tool that every adult man needs almost daily, electric razors are popular due to their ease of use and safety. Electric razors cut hair through the high-speed rotation or reciprocating oscillation of their blades. This high speed generates a significant amount of heat, causing the entire blade head to heat up. Since the blade head of an electric razor needs to be in close contact with the skin during use, the high temperatures generated during operation can cause a burning sensation on the user's skin, even causing redness and swelling. This poor heat dissipation, especially in the hot summer months, can severely impact the user experience.

[0003] There are some manual or electric shavers with cooling functions on the market, which can effectively relieve the discomfort during shaving. Their cooling structures are roughly as follows: the first type is seen in patent CN220146011U, a shaver with a temperature control function, in which a cooling plate is arranged under the cutter head, and the cooling effect is transferred to the skin through a bracket-shaped heat transfer member arranged between multiple shaver heads. This arrangement has a certain cooling effect, but the contact area with the skin is very small, generally only a narrow strip, and the cooling effect is limited; the second type is seen in patent CN216180734U, a rotary electric shaver with a cooling function, in which a cooling component is arranged under the cutter head, and the cooling sensation generated by the cooling component is transferred to the blade net through the transfer part. The blade net contacts the user's skin to cool down. This arrangement has the same problems as the previous method. First, the cooling area is limited. Second, when energy is transferred to the blade net through the transfer part, a certain amount of energy will be lost, and the cooling effect will be greatly reduced, and the user will experience a poor cooling effect.

[0004] Secondly, when using a razor, broken hair will remain on the blade net and blades, and skin oil will stick to them. If not cleaned in time, bacteria will breed and odor will be produced. The next time you use it, when a small wound appears on the skin, there will be a risk of infection. However, the blade net is generally in the shape of a honeycomb mesh, which is easy to not be cleaned properly by ordinary washing or blowing, and the blades are often thin and sharp, making them difficult to clean. In order to ensure the hygiene and safety of the blade head, existing razors have ultraviolet lamps installed on the blade head cover to sterilize the blade head. However, there are problems. On the one hand, in order to power the ultraviolet lamp, a battery must be installed in the blade head cover, which makes the blade head cover bulky and unsightly. On the other hand, turning on the disinfection function often requires manual operation. Most office workers are always in a hurry in the morning, and it is easy to forget to turn on the disinfection function of the razor after using the product.

[0005] In summary, shavers are care tools that are used frequently in daily life. In view of the various problems described above, this application aims to propose a safe and convenient multifunctional electric shaver to meet people's daily use needs. Utility Model Content

[0025] Beneficial effects of the utility model:

[0026] This application provides an ice-sensing blade assembly for an electric shaver:

[0027] The cooling plate is directly installed on the knife seat that contacts the skin. The heat is transferred directly to the knife seat without passing through other heat transfer parts, cooling the skin. The heat conduction loss is small and the cooling effect is good.

[0028] The cooling fins use semiconductor cooling fins, the heat dissipation shrapnel uses copper shrapnel, and the knife seat uses aluminum alloy with good thermal conductivity. When working, one side of the cooling fin absorbs heat and the other side dissipates heat, absorbing the heat from the knife seat and quickly dissipating it through the copper shrapnel, which can effectively reduce the temperature of the knife seat.

[0029] The blade holder not only serves as a mounting base for the blade head, but also acts as a cooling element between the cooling plate and the skin. No additional cooling plate transmission bracket is required, resulting in a simpler structure. It also has the advantages of a large cooling area and good cooling effect, which can enhance the user's cooling experience during shaving and reduce skin sensitivity and redness and swelling caused by heat.

[0030] The present application provides an electric shaver, wherein the blade holder and the body are connected magnetically, which is convenient for disassembly and removal for cleaning. The protective cap and the blade holder are also connected magnetically. Compared with the snap-on connection method in the prior art, the operation is simple and labor-saving, and it is not easy to fall off the blade head assembly. It can also avoid the problem of loose connection caused by wear of the buckle due to long-term use.

[0031] The present application provides an electric shaver, whose protective cover and body cover are separated at the upper and lower parts of the cutter head assembly, and both are provided with ultraviolet lamp panels, which are powered by the power supply in the body and do not require additional batteries; when shaving, a group of ultraviolet lamps arranged in the body are turned on at the same time as the shaver is started. After shaving, the cutter head assembly is removed and the ultraviolet lamps are stopped to avoid irradiation to human eyes. After cleaning, the protective cover is put on and the ultraviolet lamp in the protective cover starts working. The combination of the two can disinfect and sterilize the cutter head assembly in all directions, reduce bacterial growth, and avoid biological damage caused by bacterial residue.

DETAILED DESCRIPTION

[0041] The following will be combined with the accompanying drawings to clearly describe the technical solutions in the specific embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of this application, not all of them. All other embodiments obtained by ordinary technicians in this field based on the following embodiments are within the scope of protection of this utility model.

[0042] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0043] The ice-sensing blade assembly and the electric shaver including the blade assembly provided in this application are essential daily care appliances and have the advantages of being safe and convenient, having a good cooling effect, and being able to sterilize and disinfect the blade assembly. The advantages are as follows:

[0044] Ice-sensing blade assembly, used in shavers, see Figure 3 and Figure 4 , including a knife seat 1, a cutting piece 2, a knife seat cover 3 and a refrigeration piece 4. The refrigeration piece 4 directly transmits the cool feeling to the knife seat 1, that is, the skin feels cool when it touches the knife seat 1.

[0045] The blade holder 1 is configured as a receiving cavity with a heat transfer function, the purpose of which is to conduct heat;

[0046] The cutting piece 2 is suspended on the blade holder 1 and has a telescopic floating design, which can change the angle according to the face shape, so that the blade holder 1 and the cutting piece 2 can maintain a relatively full contact with the face during the shaving process;

[0047] The knife seat cover 3 is configured as a mounting plate of the knife seat 1 and together with the knife seat 1 forms an installation space for the refrigeration component 4;

[0048] The refrigeration unit 4, see Figure 3, including a cooling fin 401, a heat dissipation spring 402 and a power supply board 403 fixedly installed on the knife seat cover 3 from top to bottom, wherein the cooling fin 401 is in contact with the knife seat 1 for heat transfer. The cooling fin 401 is directly arranged on the knife seat 1 in contact with the skin. The heat is transferred directly to the knife seat 1 without passing through other heat transfer parts, thereby cooling the skin. The heat conduction loss is small and the cooling effect is good.

[0049] Specifically, as a preferred embodiment, the blade holder 1 is an aluminum alloy blade holder. The cooling fins 401, when in operation, absorb heat from the blade holder 1, thereby creating a cooling effect on the blade holder 1. Aluminum alloy has excellent thermal conductivity, resulting in a significant cooling effect. Compared to using a blade net as a heat transfer medium, or adding a "mounting seat" to the blade holder as a heat transfer medium, the blade net is generally stamped from extremely thin stainless steel, and its heat transfer speed is not as fast as that of aluminum alloy. Furthermore, the contact area between the blade net and the face, and the contact area between the "mounting seat" and the face, are both smaller than the contact area between the blade net and the face, resulting in a different cooling effect.

[0050] Specifically, the power supply board 403 and the copper shrapnel are fixed to the knife seat cover 3 by screws. When the power is turned on, one side of the cooling plate 401 absorbs heat and the other side dissipates heat. The heat dissipating side is tightly attached to the heat dissipating shrapnel 402. The heat dissipating shrapnel 402 is a copper shrapnel with excellent thermal conductivity and can also increase the heat dissipation area. Heat dissipating silicone grease is also coated between the cooling plate 401 and the heat dissipating shrapnel 402 to increase the heat dissipation speed.

[0051] As a preferred solution, the cooling plate 401 is a semiconductor cooling plate. The selection of semiconductor cooling plates also has the following advantages: no refrigerant is required, there is no pollution source, and it is green and environmentally friendly; it is a solid sheet, has no rotating parts, and will not produce a rotation effect; unlike traditional mechanical cooling devices, thermoelectric coolers basically do not generate any electronic interference signals during operation, nor do they generate any noise during operation; semiconductor cooling plates are current transduction type plates, which can achieve precise temperature control within a range of 0.1°C by controlling the input current.

[0052] It should be further explained that, in some other embodiments, the cooling plate 401 may also be made of other materials such as a ceramic cooling plate, and this is not limited here.

[0053] In this embodiment, see Figure 4The cutter head assembly is used in a rotary shaver, and the cutting element 2 is configured to include at least one set of cutter heads 5. The number of cutter heads 5 corresponds to the number of mounting holes provided on the cutter holder 1 and the cutter holder cover 3. Specifically, each set of cutter heads 5 includes a blade 501, a cutter net 502, and a cutter net fixing frame 503. It should be noted that in some other embodiments, the number of cutter heads 5 can be two, three, or even more, and this is not limited here.

[0054] In other embodiments, the refrigeration component 4 mentioned above can also be used for reciprocating shavers. The purpose is that when the shaver is working and the refrigeration function is turned on, the refrigeration plate 401 can transfer heat directly to the blade holder 1 without passing through other intermediate transfer parts, so as to achieve an efficient cooling function. There is no restriction on this.

[0055] By adopting the above solution, the design of the ice-sensing blade head assembly enables the cooling plate 401 to be directly set on the blade holder 1 in contact with the skin. The heat is transferred directly to the blade holder 1 without passing through other heat transfer parts, thereby cooling the skin. The heat conduction loss is small and the cooling effect is good. Secondly, the blade holder 1 is both a mounting seat for the blade head and a cooling transmission body between the cooling plate 401 and the skin. There is no need to additionally set up a cooling plate transmission bracket, and the structure is simpler. At the same time, it has the advantages of a large cooling area and a good cooling effect, which can enhance the user's ice-sensing experience during shaving and reduce skin sensitivity and redness and swelling caused by heat.

[0056] In addition, the present application also provides an electric shaver, see Figure 1 and Figure 2 , including the above-mentioned ice-sensing blade head assembly, having all the features and advantages of the above-mentioned blade head assembly, and also including a protective cover 6 and a body 7 respectively arranged above and below the ice-sensing blade head assembly and magnetically connected to the ice-sensing blade head assembly.

[0057] In this embodiment, see Figure 5 The relationship between the internal components of the body 7 is as follows: the body 7 includes a transparent body cover 8, a body shell 9, a power supply 10 arranged in the body shell 9, a transmission assembly 11 electrically connected to the power supply 10, a main board 12, an adapter board 13 and a first sterilization assembly 14; the power supply 10 provides energy for each component, the transmission assembly 11 includes a motor 1101 and a gear set 1102 connected to the cutting element 2, and the gear set 1102 rotates when the motor 1101 is turned, thereby providing power to the cutter head 5; the main board 12 controls each component, and the adapter board 13 transfers the energy provided by the power supply 10 to the cutter head assembly and each sterilization assembly.

[0058] For details, see Figure 5 and Figure 6One end of the adapter plate 13 is connected to the power supply 10, and the other end supplies power to the power supply board 403, the first sterilization component 14 and the second sterilization component 15 through a conductive component. The power supply board 403 is provided with a first conductive copper column 17, and the adapter plate 13 is provided with a second conductive copper column 18. The power supply board 403 is electrically connected to the adapter plate 13 through the cooperation of the first conductive copper column 17 and the second conductive copper column 18, so that the energy in the power supply 10 is provided to the power supply board 403 through the adapter plate 13, and then supplies power to the refrigeration component 4.

[0059] In this embodiment, the protective cover 6 is connected to the cutter head assembly by magnetic attraction. Compared with the clamping method in the prior art, the operation is simple and labor-saving, and it is not easy to fall off the cutter head assembly. It can also avoid the problem of loose clamping caused by wear of the buckle due to long-term use. It is specifically achieved through the following scheme:

[0060] See Figure 3 and Figure 4 A transparent mounting plate 16 is provided in the protective cover 6, wherein a second magnet is provided above the transparent mounting plate 16, and the transparent mounting plate 16 and the knife net 502 are configured to be magnetically connected, whereby the knife net 502 plays the role of being adsorbed by the second magnet.

[0061] In this embodiment, the body 7 and the cutter head assembly are connected by magnetic attraction, which facilitates disassembly and facilitates the removal of the cutter head assembly from the body 7 for cleaning. Specifically, this is achieved through the following scheme:

[0062] See Figure 5 and Figure 6 The knife seat cover 3 and the transparent body cover 8 are configured to be magnetically connected. The upper surface of the knife seat cover 3 is provided with a first magnet, and the lower surface of the transparent body cover 8 is provided with a matching magnetic attraction sheet at a position corresponding to the position of the magnet. Since the knife seat 1 and the knife seat cover 3 are fixed, the cutter head assembly can be magnetically fixed to the body through the magnetic attraction between the knife seat cover 2 and the transparent body cover 8. Compared with other snap-on, screw-type or threaded connection methods, this connection and disassembly is more convenient, which is convenient for users to clean the cutter head.

[0063] In this embodiment, in order to ensure the hygiene and safety of the cutter head, the electric shaver has the function of automatic sterilization and disinfection. Ultraviolet light panels are provided in the protective cover 6 and the transparent body cover 8, and are powered by the power supply 10 in the body 7, without the need for additional batteries.

[0064] Specifically, the body 7 sterilizes and disinfects the cutter head assembly through the following scheme:

[0065] See Figure 5The first sterilization component 14 includes a first ultraviolet lamp board arranged on the adapter plate 13. The adapter plate 13 supplies power and controls the first ultraviolet lamp board. The first ultraviolet lamp board is located under the transparent body cover 8. When the shaver is turned on, the first ultraviolet lamp board is automatically turned on synchronously. Since the body cover is made of transparent material, ultraviolet rays can pass through the body cover to sterilize and disinfect the cutter head assembly. After shaving, remove the cutter head assembly and stop the ultraviolet lamp to avoid irradiation to human eyes.

[0066] Specifically, the protective cover 6 sterilizes and disinfects the cutter head assembly through the following scheme:

[0067] See Figure 4 A second sterilization component 15 is provided in the protective cover 6. The second sterilization component 15 includes a second ultraviolet lamp board arranged on the transparent mounting plate 16. The setting of the transparent mounting plate 16 can be used to fix the second magnet that is magnetically attracted to the knife net, and secondly, it can isolate water from entering the second ultraviolet lamp board, thereby playing a certain protective role.

[0068] Furthermore, the second sterilization assembly 15 includes a second ultraviolet lamp board disposed on the transparent mounting plate, the second ultraviolet lamp board being provided with a third conductive copper post 19, and the adapter plate 13 being provided with a fourth conductive copper post 20. The second ultraviolet lamp board is electrically connected to the adapter plate 13 through the cooperation of the third conductive copper post 19 and the fourth conductive copper post 20, thereby transferring energy from the power supply in the body 7 to the second ultraviolet lamp board. Since no battery is provided in the protective cover 6, the structure is simpler and thinner, and the protective cover 6 is magnetically attached to the blade mesh securely (if the protective cover is too heavy, the protective cover will not be magnetically attached securely when the shaver is inverted).

[0069] Furthermore, the mounting plate is also made of transparent material, which can ensure that ultraviolet rays can pass through the mounting plate to irradiate the cutter head assembly. The second ultraviolet lamp board can sterilize and disinfect the upper surface of the cutter head assembly (i.e., the contact surface between the cutter head assembly and the skin). Combined with the first ultraviolet lamp board, the cutter head assembly can be fully disinfected; the second ultraviolet lamp board is automatically turned on after the protective cover 6 is closed on the cutter holder 1, and automatically turns off after a certain period of time.

[0070] In addition, the above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
