TECHNICAL FIELD
[0001] The utility model relates to the field of trimming equipment, especially a hair trimmer. BACKGROUND
[0002] In daily life, hair trimmers, especially hair scissors, have become common tools for people to manage their hair. Traditional hair trimmers often have some deficiencies in the use process. With the continuous improvement of people's requirements for trimming effect and use experience, the existing hair trimmers are prone to have the problem of cutter jamming in long-term use, which not only affects the trimming efficiency, but also may have adverse effects on the trimming quality.
[0003] On the one hand, the traditional hair trimmer usually does not consider the lubrication and maintenance of the trimming part in the design. In frequent trimming operations, the friction between the trimming parts will gradually increase, and the lack of effective lubrication measures will cause the cutter to run smoothly, and then the jamming phenomenon occurs. On the other hand, the existing methods to solve the jamming problem are not ideal, for example, the method of adding lubricating oil is often troublesome, and it is difficult to ensure that the lubricating oil can uniformly cover the trimming part.
[0004] In order to solve the above problems, the hair trimmer of the utility model innovatively designs a detachable oil storage structure at the trimming part. The oil storage structure can store essence oil and other lubricating substances inside. When in use, the user can conveniently take it down and make the internally stored essence oil completely cover the trimming part through pressing and other operations. In this way, not only can the problem of cutter jamming in long-term use be effectively avoided, but also a more convenient and efficient use experience is provided for the user. CONTENT OF THE UTILITY MODEL
[0005] The utility model aims at the deficiencies in the prior art, sets the oil storage structure with essence oil between the first trimming head and the second trimming head, and evenly applies the essence oil to the trimming part through the brush structure and the transmission structure, effectively reduces the friction between the trimming parts, and avoids the occurrence of the cutter jamming problem. This makes the trimming process more smooth, greatly improves the trimming efficiency, and at the same time ensures the trimming quality, so that the trimmed hair is more neat and beautiful.
[0006] In order to solve the above technical problems, the utility model avoids the problem of cutter jamming in the trimming head part in long-term use of the trimmer, and makes the user operation more convenient through the following technical scheme.
[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0008] A hair trimmer includes a first trimming head and a second trimming head mounted on a hair trimmer body. The first and second trimming heads are installed at the front end of the hair trimmer body for trimming.

[0017] Preferably, the length of the brush structure is designed to be greater than that of the transmission structure and to cover the portion of the transmission structure.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] The hair trimmer provided in this application utilizes an oil-reservoir structure between the first and second trimming heads. This oil is then evenly applied to the trimming area via a brush and transmission structure, effectively reducing friction between the trimming components and preventing blade jamming. This results in a smoother trimming process, significantly improving efficiency while ensuring quality and producing neater, more aesthetically pleasing hair.
[0020] This application features a liquid inlet at one end of the oil storage structure for convenient addition of essential oil. The external cap and internal elastic sealing plug of the inlet form a robust seal, preventing leakage. Users can easily add essential oil simply by opening the cap.

Example
[0037] Please see Figures 1-8A hair trimmer includes a first trimming head 2 and a second trimming head 201 mounted on a hair trimmer body 1. The first trimming head 2 and the second trimming head 201 are mounted on the front end of the hair trimmer body 1 for trimming. There is a gap between the first trimming head 2 and the second trimming head 201, and a detachable oil storage structure 3 is provided in the gap. One end of the oil storage structure 3 is provided with an inlet 301 to facilitate the addition of essential oil to lubricate the trimming part. The other end of the oil storage structure 3 is connected to a transmission structure 5 through a brush structure 4.
[0038] The hair trimmer of this application is mainly composed of hair trimmer body 1, first trimmer head 2, second trimmer head 201, oil storage structure 3, liquid inlet 301, brush structure 4 and other components. The following is a detailed description of the structure and working principle.
[0039] (I) Overall Structure
[0040] Hair trimming machine body 1
[0041] The hair trimmer body 1 is the core supporting part of the entire hair trimmer. It contains a drive motor and other power devices to power the operation of the trimming heads. The external design of the body is ergonomic, making it easy for users to hold. It is usually made of plastic, which ensures a certain strength while making the entire trimmer relatively lightweight. At the front of the body, the first trimming head 2 and the second trimming head 201 are precisely installed. These two trimming heads are key components that directly contact the hair to perform the trimming operation.
[0042] Trimming head structure
[0043] First trimming head 2:
[0044] The first trimming head 2 plays a crucial role in the hair trimmer. It uses durable metal as the base material for the blade, which undergoes precision machining and polishing to ensure its sharpness and effective hair-cutting capability. Inside the first trimming head 2, two sets of positioning slots 2001 are specially designed. These two sets of structures are designed to cooperate with the positioning plates 601 at both ends of the outer support frame 6, thereby achieving the positioning and fixation of the oil storage structure 3.
[0045] Second trimming head 201:
[0046] The second trimming head 201 is also made of high-quality metal and, together with the first trimming head 2, forms the working components for trimming hair. A certain gap exists between the two; this gap is precisely designed to ensure that hair can smoothly enter the trimming area during the trimming process, and to provide installation space for the oil storage structure 3 and its related components. The positioning slot 2001 on the second trimming head 201 is shaped and sized to fit snugly with the positioning plate 601, ensuring accurate positioning and sufficient stability when installing the oil storage structure 3.
[0047] (II) Oil Storage Structure 3
[0048] Materials and Design:
[0049] The oil reservoir 3 is made of rubber and has a certain degree of transparency. Rubber has excellent elasticity, allowing it to easily deform during compression, thus squeezing out the stored essential oil. At the same time, rubber also has good flexibility and wear resistance, maintaining the structural integrity during long-term use. The transparency is extremely convenient for users, allowing them to directly see the remaining amount of essential oil inside the reservoir 3. When using a hair trimmer, users need to know when to add essential oil to ensure the trimming head is always well lubricated. If the oil reservoir 3 is transparent, users can clearly see the amount of essential oil inside simply by visual inspection, without needing to open the cap 302 or perform other complicated operations for checking.
[0050] The inlet 301 is located at one end of the oil storage structure 3. Its size is appropriately sized to facilitate the injection of essential oil while ensuring no leakage during normal use. The cap 302 tightly covers the inlet 301, and the internal sealing plug 303 is made of highly elastic rubber. When the cap 302 is closed, the internal sealing plug 303, due to its elasticity, can be tightly inserted into the opening of the inlet 301, forming a reliable seal. This sealing structure effectively prevents essential oil from leaking out of the inlet 301 when not in use, ensuring the airtightness of the oil storage structure 3.
[0051] Anti-slip design:
[0052] Anti-slip grooves 3001 are uniformly provided on the outer surface of the oil storage structure 3. The shape and depth of these anti-slip grooves 3001 are carefully designed so that when the user holds the oil storage structure 3 to perform the liquid filling operation, the fingers can make close contact with the anti-slip grooves 3001, increasing the friction between the hand and the oil storage structure 3, effectively preventing the hand from slipping and ensuring the smooth progress of the liquid filling operation.
[0053] Export structure:
[0054] The end of the oil storage structure 3 facing the brush structure 4 is designed as a mesh structure 3002, the pore size and distribution density of which are optimized. The purpose is to ensure that the essential oil can pass smoothly through the mesh into the transport structure 5 during extrusion, while preventing the porous fiber material in the transport structure 5 from entering the interior of the oil storage structure 3 during long-term use.
[0055] Fixed structure:
[0056] The outer support frame 6 is tightly connected to the oil storage structure 3. The connecting collar 602 of the outer support frame 6 is made of a hard plastic material compatible with the material of the oil storage structure 3, which can firmly fit around the outer periphery of the oil storage structure 3, thus stabilizing the oil storage structure 3. The positioning plates 601 at both ends of the outer support frame 6 are made of hard plastic material, possessing a certain rigidity and strength. During installation, the positioning plates 601 are engaged through the opening of the positioning groove 2001 inside the first trimmer head 2. Due to the certain friction between the opening of the positioning groove 2001 and the positioning plate 601, this friction is achieved through the precise design of the opening and plate dimensions, as well as the surface roughness of the material, ensuring that the oil storage structure 3 is stably positioned within the gap between the first trimmer head 2 and the second trimmer head 201. Moreover, this installation method ensures that the oil storage structure 3 is located within the gap between the trimmer heads, not reaching the trimming part of the blade, which is convenient for future use and also has a certain degree of concealment, without affecting the normal appearance and use of the trimmer.
[0057] (III) Structure for the delivery and application of essential oils
[0058] Brush Structure 4
[0059] The length design of the brush structure 4 is a key factor. Its length is greater than the width of the trimming areas of the first trimming head 2 and the second trimming head 201, and also greater than the length of the transmission structure 5, covering the portion of the transmission structure 5. This design ensures that the brush structure 4 can fully cover the working area of the trimming head. The bristles of the brush structure 4 are typically made of soft and resilient nylon material. This material effectively and evenly coats the essential oil transferred from the oil storage structure 3 onto the trimming structure when in contact with the trimming head, without damaging the trimming head.
[0060] Transmission Structure 5
[0061] The delivery structure 5 uses porous fibrous materials, such as sponges and fiber cotton. Sponge materials have a rich porous structure, and these pores are interconnected, forming channels for the delivery of essential oils. Fiber cotton has a better fiber arrangement structure, which can maintain a certain degree of shape stability while ensuring the delivery of essential oils.
[0062] One end of the transmission structure 5 is tightly connected to the brush structure 4 using either adhesive bonding or mechanical nesting. For example, a groove matching the shape of the transmission structure 5 is provided at the base of the brush structure 4, one end of the transmission structure 5 is embedded in it, and then fixed with adhesive to ensure a strong connection. The other end is connected to the mesh structure 3002 end of the oil storage structure 3, using a similar method. Through this connection, the oil storage structure 3, transmission structure 5, and brush structure 4 together form a channel for the flow of essential oil, ensuring that the essential oil can be smoothly transferred from the oil storage structure 3 to the brush structure 4.
[0063] II. Detailed Working Principle
[0064] (a) Adding essential oils
[0065] When it is necessary to add essential oil to the hair trimmer, the user should first locate the inlet 301 on the oil reservoir 3. The inlet 301 is usually located at one end of the oil reservoir 3 and is covered by a cap 302.
[0066] The user carefully opens the cap 302. Because the built-in sealing plug 303 inside the cap 302 fits tightly against the inlet 301, some force may be required when opening the cap 302. After opening the cap 302, the user can use a special oil dispenser or small dropper to slowly inject the essential oil into the oil storage structure 3 through the inlet 301. During the injection process, care should be taken to prevent the essential oil from overflowing from the inlet 301.
[0067] After the essential oil has been added, replace the cap 302 on the inlet 301. At this time, the internal sealing plug 303, due to its elasticity, will be tightly inserted into the opening of the inlet 301, forming a tight seal to prevent the essential oil from leaking out of the inlet 301 during storage and use.
[0068] (ii) Essential oil delivery
[0069] When the user needs to lubricate the trimmer head, they will squeeze the oil reservoir 3. Because the oil reservoir 3 is made of rubber, it has good elasticity and will undergo elastic deformation when squeezed by fingers or other tools.
[0070] This elastic deformation reduces the internal volume of the oil storage structure 3, thereby generating pressure. Under pressure, the essential oil inside the oil storage structure 3 will enter the transmission structure 5 through the mesh structure 3002 at one end.
[0071] The porous fiber material of the transport structure 5 utilizes the principle of capillary action to transport the essential oil. When the essential oil comes into contact with the porous fiber material of the transport structure 5, it rises and flows within the pores of the fiber material due to capillary action. By adjusting the pore size, length, and thickness of the porous fiber material, the flow rate of the essential oil can be controlled. For example, if the pores are smaller and the channels are longer, the flow rate of the essential oil in the transport structure 5 will be slower. This prevents too much essential oil from being transferred to the brush structure 4 at once, thus achieving precise control over the amount of essential oil transported.
[0072] (III) Applying essential oil and lubricating the trimmer head
[0073] After being transported through capillary action in the transport structure 5, the essential oil permeates the brush structure 4. Because the bristles of the brush structure 4 are tightly connected to the transport structure 5, the essential oil can be evenly distributed on the bristles.
[0074] The brush structure 4 is designed to be long enough to cover the trimming head area. When the user brings the brush structure 4 into contact with the trimming head (applying the oil longitudinally along the blade), the essential oil on the bristles is evenly coated onto the trimming structure formed by the first trimming head 2 and the second trimming head 201, i.e., the blade. During this process, the bristles of the brush structure 4 are soft and resilient, allowing them to adhere closely to the surface of the trimming head and ensuring that the essential oil fully covers the working area of the trimming head.
[0075] After the essential oil is applied to the trimmer head, it forms a lubricating layer on the blades and other key components. This lubricating layer effectively reduces friction between the trimmer parts, especially during long-term use, preventing blade jamming caused by friction. At the same time, the essential oil itself is lubricating and will not damage the hair; it also provides some protection during the trimming process, resulting in smoother, more manageable hair after trimming.
[0076] Throughout the entire process of use, the outer support frame 6 and its connecting collar 602 provide stability for the oil storage structure 3. The outer support frame 6 can prevent the oil storage structure 3 from shifting or shaking during squeezing and use, ensuring that the essential oil can be smoothly transferred from the oil storage structure 3 to the brush structure 4 and evenly applied to the trimming head, thereby achieving efficient, smooth and lubricated trimming operation of the hair trimmer and improving the user experience.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments.
