Description
Technical Field The present invention relates to the technical field of airbag combs, and more particularly, to an airbag comb. Background Art An airbag comb adopts an air cushion structure, that is, comb needles of a hair comb are arranged on a flexible base body, and the base body is installed on a substrate and is convex in an arc shape. In this way, when combing, with the force applied by a user, the base body will be deformed according to the shape of the skull, so that the comb needles are enabled to better fit on the scalp, and the user will not feel discomfort on the scalp due to the protrusion of the skull. At present, for most of rubber combs of the same type on the market, rubber sheets thereof are cut from sheets and then extruded to have a certain protrusion. Such combs usually only have elasticity in the middle, with little or no elasticity at edges, and their overall elastic spaces are small. After a period of use, it is easy to collapse due to poor rubber fixation, resulting in a short service life and unsatisfactory user experience. Therefore, there is an urgent need for an airbag comb to solve the above-mentioned problems.

Detailed Description of the Invention The technical solution of the present patent will be further described in detail below in conjunction with specific implementations. Embodiment 1 Referring to FIG. 1 to FIG. 6, an airbag comb is provided, which includes a comb holder 1. One side of the comb holder 1 is provided with a handle 2, and the comb holder 1 is integrally formed with the handle 2. A cross section of the comb holder 1 is elliptical. An annular clamping slot 7 is formed inside the comb holder 1, and a matching ring strip 6 is clamped in the annular clamping slot 7. A top outer wall of the matching ring strip 6 is fixedly connected with an airbag rubber sheet 4, and comb teeth 3 are arranged on one side of the airbag rubber sheet 4 away from the matching ring strip 6. An exhaust hole 5 is provided in a bottom inner wall of the comb holder 4 1. By designing the matching ring strip 6 with a double-arc structure, it is more convenient for people to install or disassemble the airbag rubber sheet 4, and the overall thickness is reduced under the premise of ensuring the elasticity, so as to make the structure more compact. Furthermore, the airbag comb is attractive in appearance, thus meeting the usage requirement of people. To comb people’s hair better, referring to FIG. 6, each of the comb teeth 3 includes a tooth body 3001, a supporting portion 3002, a fixing portion 3003, a locking portion 3005 and a head portion 3004. An inner diameter of the tooth body 3001 gradually decreases in a direction away from the airbag rubber sheet 4, and cross sections of the supporting portion 3002, the fixing portion 3003 and the locking portion 3005 are I-shaped. The stability of the comb teeth 3 after installation can be ensured through the locking portions 3005. To improve the comfort of people during use, referring to FIG. 6, the head portion 3004 is provided at the end of the tooth body 3001 away from the supporting portion 3002, and a cross section of the head portion 3004 is circular. Due to the circular cross-section, the head portion 3004 makes people have better tactile sensation when in contact with people’s scalp and also has the effect of massaging the scalp. To ensure the stable installation of comb teeth 3, referring to FIG. 6, the airbag rubber sheet 4 is provided with mounting holes 8 in a top outer wall. The locking portions 3005 are located inside the mounting holes 8. Bottom outer walls of the supporting portions 3002 are in contact with top outer walls of the corresponding mounting holes 8, and top outer walls of the locking portions 3005 are in contact with bottom outer walls of the corresponding mounting holes 8. The effective engagement between the locking portions 3005 and the mounting holes 8 ensures the stability of the comb teeth 3 after installation. Embodiment 2 Referring to FIG. 7 to FIG. 9, an airbag comb is provided. Compared to Embodiment 1, this embodiment further includes an annular groove 3006 formed in a circumferential outer wall of each of the supporting portions 3002, and a bottom outer wall of the annular groove 3006 is in contact with the top outer wall of the corresponding mounting hole 8. Since the annular grooves 3006 are formed in bottoms of the supporting portions 3002, a certain space can be reserved, and the situation of hair catching caused by the supporting portions 3002 extruding a top of the airbag 5 rubber sheet 4 is avoided. To enable the comb teeth 3 to be installed more quickly, referring to FIG. 7, a sloping groove 3007 is formed in a circumferential outer wall of each of the locking portions 3005, and a cross section of the locking portion 3005 is an isosceles trapezoid, which makes it easier for the end of the locking portion 3005 to pass through the interior of the mounting hole 8, thereby improving the installation efficiency of the comb teeth 3. To avoid sinking of the comb teeth 3 after installation, referring to FIG. 7, a positioning convex ring 3008 is fixedly connected to the circumferential outer wall of each of the locking portions 3005. A positioning groove 9 is formed in each of the mounting holes 8. The positioning convex rings 3008 are in clamping connection with the positioning grooves 9, and diameters of bottom outer walls of the positioning convex rings 3008 are larger than those of top outer walls thereof. Through the arrangement of the positioning convex rings 3008 on the circumferential outer walls of the locking portions 3005, the positioning convex rings can be well matched with the positioning grooves 9, thus ensuring the stability of the comb teeth 3 after installation and avoiding sinking of the comb teeth 3. Embodiment 3 Referring to FIG. 10 to FIG. 12, an airbag comb is provided. Compared to Embodiment 1, this embodiment further includes a boss portion 10 fixedly connected to a top of the comb holder 1. The exhaust hole 5 passes through a center of the boss portion 10, and a pressure regulating assembly is arranged inside the boss portion 10, so that the elasticity of the entire airbag comb can be adjusted according to different usage habits of people, and the usage requirements of different people are met. To adjust the elasticity of the airbag comb, referring to FIG. 12, the pressure regulating assembly includes an adjusting seat 16 fixedly connected to a circumferential inner wall of the boss portion 10, and an adjusting groove is formed in the adjusting seat 16. Cross sections of the adjusting seat 16 and the adjusting groove are both circular. The adjusting groove is communicated with the exhaust hole 5. An adjusting shell 11 is rotatably connected inside the adjusting groove. A through groove 17 is formed in a circumferential outer wall of the adjusting shell 11, and the through groove 17 penetrates through the adjusting shell 11. A rotating rod 15 is fixedly connected to the circumferential outer wall of the adjusting shell 11, and one end of the 6 rotating rod 15 passes through the interior of the boss portion 10. A groove 12 is formed in a bottom outer wall of the comb holder 1, and one end of the rotating rod 15 is located inside the groove 12. When in use, it is found that if the elasticity of the airbag comb is too strong, the rotating rod 15 can be enabled to rotate. During the rotation of the rotating rod 15, the adjusting shell 11 can be driven to rotate in the adjusting groove inside the adjusting seat 16. When the through groove 17 is not in the same vertical plane as the exhaust hole 5, a ventilation volume of the entire exhaust hole 5 will decrease. When an exhaust volume of the exhaust hole 5 decreases, a deformation speed of the airbag rubber sheet 4 will also slow down, thus effectively reducing the elasticity of the airbag rubber sheet 4 and meeting the usage requirement of people. To facilitate people to better rotate the rotating rod 15, referring to FIG. 12, the rotating rod 15 is fixedly connected with a rotatable handle 14 at the end located inside the groove 12, and a circumferential outer wall of the rotatable handle 14 is provided with anti-skid grooves 13 distributed in a circular shape at equal intervals. Working principle: the airbag rubber sheet 4 is designed with a three-dimensional structure, so that the independent protruding support of the airbag rubber sheet 4 can be realized, and the failure in effectively fitting the scalp caused by middle depression after long-term use is avoided. Furthermore, the three-dimensional design of the airbag rubber sheet 4 makes the airbag rubber sheet have better elasticity, which ensures the comfort during use and effectively prolongs the overall service life of the airbag comb. By designing the matching ring strip 6 with a double-arc structure, it is more convenient for people to install or disassemble the airbag rubber sheet 4, and the overall thickness is reduced under the premise of ensuring the elasticity, so as to make the structure more compact; and moreover, the airbag comb is attractive in appearance, thus meeting the usage requirement of people. When people use the airbag comb, the comb teeth 3 will tilt under the force of combing hair. Since the annular grooves 3006 are formed in the bottoms of the supporting portions 3002, a certain space can be reserved, and the situation of hair catching caused by the supporting portions 3002 extruding the top of the airbag rubber 4 is avoided. Through the arrangement of the positioning convex rings 3008 on the circumferential outer walls of the locking portions 3005, the positioning convex rings can be well matched with the positioning grooves 9, thus ensuring the stability of the comb teeth 3 after installation and avoiding sinking of the comb teeth 3. When in use, it is found that if the elasticity of the airbag comb is too strong, the rotatable 7 handle 14 located inside the groove 12 can be enabled to rotate through pushing, and the rotation of the rotatable handle 14 can drive the rotating rod 15 to rotate together. During the rotation of the rotating rod 15, the adjusting shell 11 can be driven to rotate in the adjusting groove inside the adjusting seat 16. When the through groove 17 is not in the same vertical plane as the exhaust hole 5, the ventilation volume of the entire exhaust hole 5 will decrease. When the exhaust volume of the exhaust hole 5 decreases, the deformation speed of the airbag rubber sheet 4 will also slow down, thus effectively reducing the elasticity of the airbag rubber sheet 4 and meeting the usage requirement of people.
