Description

Technical Field

[0001] This utility model relates to the field of hair styling tools, specifically to a novel hair comb that combines a hot air comb and a straightening comb. Background Technology

[0002] Currently, in hair styling, hot air combs are mainly used to dry hair and create volume, while straightening combs are used to straighten hair and make it smooth. Examples include the electric hot air straightening comb in CN104856417A and an electric hot air comb in CN117582058A. However, existing hot air combs and straightening combs are independent tools, which may require users to frequently switch between them during hair styling, making operation inconvenient and taking up a lot of storage space. To solve the above problems, this utility model proposes a hair comb that combines a hot air comb and a straightening comb to improve hair styling efficiency and convenience. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art by providing a dual-purpose comb that combines hot air and straightening functions, reducing the number of hair styling tools and making it convenient for users to operate and store.

[0004] The technical solution of this utility model is as follows: A direct-heating and air-cooling comb includes a handle and a comb head at the upper end of the handle. A control circuit module and a fan are arranged in the inner cavity of the handle, and an air inlet is provided on the handle. The comb head has a barrel frame and a hot air comb head and a straightening comb head respectively arranged on both sides of the barrel frame. The hot air comb head and the straightening comb head cooperate to form a comb barrel. The straightening comb head includes a straightening comb plate and heated comb teeth densely distributed on the comb plate. The hot air comb head includes a hot air comb plate, comb teeth densely distributed on the comb plate, and an air outlet. An electric heating element is arranged in the inner cavity of the barrel frame. The inner cavity of the handle communicates with the inner cavity of the barrel frame to form an air outlet channel. A heating base plate is installed on the outer surface of the barrel frame corresponding to the straightening comb plate side. The heating base plate is used to heat the heated comb teeth. The heating base plate and the electric heating element are electrically connected to the control circuit module.

[0005] By adopting the above technical solution, when the heating element is energized, the fan simultaneously draws in air through the air inlet and blows the air into the inner cavity of the comb. After being heated by the heating element, the hot air is blown out through the air outlet, thus realizing the function of a hot air comb. When the heating plate is energized, the generated heat is transferred to the heated comb teeth, enabling the straightening comb head to heat and straighten the hair.

[0006] This design integrates both a straightening comb and a hot air comb on each side of the comb head, and the heating and air blowing modes can be easily controlled via a control circuit module to meet different user hair styling needs. At the same time, its compact structure reduces the number of hair styling tools, making it convenient for users to operate and store.

[0007] A further feature of this invention is that a rotary switch is provided on the handle, and the rotary switch has at least three rotation positions, corresponding to the off state, the straightening comb heating state, and the hot air comb hot air state, respectively.

[0008] When the knob switch is turned to the hair straightener heating position, the heating plate is activated, causing the heated comb teeth on the hair straightener head to heat up.

[0009] When the knob switch is turned to the hot air comb setting, the control fan and heating element are activated, causing the hot air comb head to blow out hot air.

[0010] With the above further settings, you can easily switch between the two functions of heating the hair straightener and heating the hot air comb by simply rotating the knob switch, making the operation simple and quick.

[0011] A further feature of this invention is that the rotary switch achieves multi-position control through a Hall effect switch in conjunction with a magnet.

[0012] With the above-mentioned further settings, this non-contact control method not only improves the product's service life, but also makes gear switching more stable and reliable.

[0013] A further feature of this invention is that the rotary switch employs a pin-positioning structure, whereby the pins engage with different grooves when the rotary switch is rotated to indicate gear shifting; the handle surface has gear position characters, and the rotary switch has pointers for pointing to different gear position characters.

[0014] With the above further design, users can intuitively understand the current gear position of the rotary switch by observing the gear indicator pointed to by the pointer. The pin positioning structure not only ensures the stability of the rotary switch during rotation, but also further enhances the user experience through the tactile feedback generated by the pins locking into different grooves.

[0015] A further feature of this invention is that the comb head is connected to the handle via a hot air comb plate.

[0016] The aforementioned further design allows the comb head to be easily and quickly installed or removed from the handle, enabling users to easily change to different sizes or types of comb heads according to their actual needs. The hot air comb plate not only provides a hot air output channel for the comb head but also ensures a secure connection between the comb head and the handle through a snap-fit ​​connection, preventing loosening or detachment during use.

[0017] A further feature of this invention is that the hot air comb plate and the tube frame are positioned by a sliding fit; the upper end of the comb tube is provided with a top cover, which is sleeved on the upper end of the hot air comb plate and the straightening comb plate.

[0018] With the above-mentioned further configuration, the hot air comb plate and the cylinder frame are positioned by sliding and inserting, which allows the hot air comb plate to slide and be positioned easily within the cylinder frame. This not only simplifies operation but also ensures the stability of the hot air comb plate within the cylinder frame, preventing shaking or displacement during use.

[0019] Meanwhile, the top cover design at the upper end of the comb tube not only provides protection for the hot air comb plate and the straightening comb plate, but also further enhances the cooperation between the hot air comb plate and the straightening comb plate by fitting it over the upper part of the comb.

[0020] A further feature of this invention is that the hot air comb plate and the cylinder frame are spaced apart to form an air cavity, and the surface of the cylinder frame is provided with a through-type air outlet, which connects the inner cavity of the cylinder frame and the air cavity.

[0021] With the further design described above, the air cavity formed between the hot air comb plate and the hair shaft provides an effective channel for hot air circulation. The through-type air vents on the surface of the hair shaft not only allow hot air to flow smoothly from the inner cavity of the hair shaft into the air cavity, but also ensure the even distribution of hot air. This design not only improves the utilization efficiency of hot air, but also allows the hot air to make more thorough contact with the hair.

[0022] A further feature of this invention is as follows: the handle includes an inner shell and an outer shell fitted over it. The inner shell has two detachable half-shells. The control circuit module and the fan are installed in the inner shell, and the inner cavity of the inner shell communicates with the inner cavity of the cylinder frame. The upper end of the inner shell extends out of the outer shell. The rotary switch is fitted on the outside of the extended part of the inner shell, and the axial positioning of the rotary switch is achieved by the cooperation between the outer shell and the inner shell.

[0023] With these further modifications, the internal structure of the handle becomes more compact and easier to disassemble and maintain. The removable two-half-shell design of the inner shell facilitates the installation and replacement of the control circuit module and the fan. The rotary switch is fitted onto the outer side of the protruding part at the upper end of the inner shell and is axially positioned through the cooperation between the outer and inner shells, facilitating the installation of the rotary switch.

[0024] A further feature of this invention is that the air inlet is located at the lower end of the handle, the handle includes an inner shell and an outer shell fitted over it, the lower end of the outer shell is provided with a detachable tail cap, the air inlet is provided at the lower ends of both the tail cap and the inner shell, and a filter element is provided between the tail cap and the inner shell.

[0025] With the above-described further design, the air inlet is positioned more rationally at the bottom of the handle, facilitating air intake and improving the fan's air intake efficiency. Simultaneously, the removable tail cap at the bottom of the casing not only makes cleaning the air inlet easier but also facilitates the replacement of filter element one. Filter element one effectively filters the incoming air, preventing dust and other impurities from entering the fan, protecting internal components, and extending its service life.

[0026] A further feature of this invention is that a second filter element is provided in the inner cavity of the handle, and the second filter element corresponds to the area below the fan.

[0027] With the further configuration described above, the second filter element is located below the fan. This allows it to intercept and filter out fine particulate matter, such as dust and pollen, from the air entering the handle through the air inlet, ensuring that the air drawn in by the fan is cleaner. This design not only improves the air intake quality of the fan but also effectively protects the internal components from impurities, further extending the fan's service life.

[0052] When a user needs to use the hair straightening function, simply rotate the knob switch to the hair straightening comb heating position (rotate the knob switch clockwise). At this time, the control circuit module receives a signal and activates the heating plate. The heating protrusions on the heating plate engage with the heating comb teeth on the hair straightening comb head, transferring heat to the heating comb teeth and causing them to heat up. The user can then use one side of the hair straightening comb head 222 to straighten their hair through its heated comb teeth.

[0053] When the user needs to use the hot air function, rotate the knob switch to the hot air comb hot air mode (rotate the knob switch counterclockwise); after receiving the signal, the control circuit module starts the fan and the heating element simultaneously; the fan draws in air through the air inlet, the air is filtered by filter element one and filter element two, and then heated by the heating element to form hot air; the hot air flows into the air cavity formed between the hot air comb head and the tube frame through the inner cavity of the tube frame, and is blown out from the air outlet of the hot air comb head, so the user can use the hot air comb head 221 on the other side to style the hair with hot air.

[0054] In summary, this utility model provides a dual-purpose comb that can be used for both straightening and hot air functions. It allows for easy switching between these functions via a simple knob switch, and its reasonable structural design and ease of use meet the diverse needs of users.
