In addition, if the steam-emitting hair straightening comb is accidentally opened when not in use, there is a risk of burns, which urgently needs to be improved. Utility Model Content

[0004] The utility model aims to provide a steam type hair straightening comb, which has the effects of preventing accidental opening, preventing dust and insect pests and being easy to operate in a stored state.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions: a steam-type straight hair comb, comprising a drive control module, a straight hair comb body and a steam generating device connected to the tail of the straight hair comb body, the straight hair comb body is provided with a steam channel, the head of the straight hair comb body is provided with a straight hair comb head, a steam outlet gap is provided between the straight hair comb head and the straight hair comb body, and the steam outlet gap is connected to the steam generating device through the steam channel; the straight hair comb body is provided with a cap, the cap has a receiving groove corresponding to the straight hair comb head, the cap is embedded with a magnet around the receiving groove, magnetic adsorption parts are symmetrically provided on both sides of the straight hair comb body, and the cap is adsorbed and fixed by the magnet and the corresponding magnetic adsorption part;

[0006] A toggle switch is provided on the side wall of the hair straightening comb body corresponding to the drive control module, and the hair straightening comb body is provided with a press-locking mechanism, and the press-locking mechanism includes a pressing portion, a locking portion and a lock slot, and the lock slot is provided on the toggle switch; when the cap is adsorbed on the magnetic adsorption portion close to one side of the hair straightening comb head, the cap is pressed and matched with the pressing portion, and pushes the locking portion to lock and match with the lock slot; the hair straightening comb body is provided with an elastic reset member, and the elastic reset member always has a tendency to drive the locking portion to move away from the lock slot.

[0007] By adopting the above technical solution, when the user uses the utility model, the cap adsorbed on the side of the straight hair comb head is separated from the magnetic adsorption part on the corresponding side of the straight hair comb body, and then the cap is adsorbed on the side of the straight hair comb body away from the straight hair comb head by using the magnetic adsorption force between the magnet of the cap and the magnetic adsorption part on the other side, and then the utility model can be used for steam combing. The utility model adopts magnetic adsorption to not only make the cap more convenient to cover, but also effectively prevent the cap from being easily lost after use. When the user finishes using the utility model, the toggle switch is turned to the off state. At this time, the cap is adsorbed on the magnetic adsorption part on the side of the straight hair comb head, so that the straight hair comb head is accommodated in the accommodating groove of the cap. The sealing effect of the cap can effectively isolate external dust and prevent dust from falling on the straight hair comb head. In addition, when the cap is closed on the hair straightening comb head, the cap will act on the pressing part to move, thereby linking the pressing and locking mechanism to actuate, and finally driving the locking part to lock in the lock slot of the toggle switch. In this process, the elastic reset part accumulates elastic potential energy, and utilizes the locking and positioning effect of the locking part and the lock slot to make it difficult to toggle the toggle switch to open, which can prevent the user from misoperating the device when the cap is in the closed state and causing it to start. When the device needs to be used again, it is necessary to first remove the cap from the magnetic adsorption part on one side of the hair straightening comb head to eliminate the pressing force of the cap on the pressing part. At this time, the elastic reset part releases the elastic potential energy and pulls the locking part away from the lock slot, so that the toggle switch is in the released position. Then the user can toggle the toggle switch to the open state, so that the utility model has the effects of preventing accidental opening, dust and insect prevention, and easy operation in the stored state.

[0008] The utility model is further configured as follows: the press locking mechanism further includes a first gear, a second gear and a rack; one end of the press portion is fixedly connected to the first gear; the rack is slidably disposed on the hair straightening comb body; the locking portion is disposed at one end of the rack close to the toggle switch; the first gear and the second gear are rotatably disposed on the hair straightening comb body and mesh with each other; and the rack meshes with the second gear.

[0009] By adopting the above technical solution, when the cap is firmly adsorbed and covered on the magnetic adsorption part on one side of the straight hair comb, the cap pushes the first gear to rotate counterclockwise, and the first gear drives the second gear to rotate clockwise, and then under the meshing action of the second gear and the rack, the rack is driven to move downward, and the locking part at the lower end of the rack is extended into the lock groove of the toggle switch, so that when the straight hair comb is covered and stored by the cap, the toggle switch can be effectively prevented from being accidentally opened.

[0010] The utility model is further configured as follows: the first gear is configured as a sector gear, the sector gear ring portion of the first gear meshes with the outer teeth of the second gear, and the first gear and the second gear are rotatably connected to the hair straightening comb body via a rotating shaft.

[0011] By adopting the above technical solution, the first gear adopts a sector gear, which can effectively reduce the installation space, so that the installation space required for the push-locking mechanism of the utility model is smaller, and the compactness of the utility model is improved.

[0012] The utility model is further configured as follows: the rack includes a toothed meshing portion and a sliding portion, the rack is meshed with the second gear through the toothed meshing portion, the sliding portion is arranged between the toothed meshing portion and the locking portion, the straight hair comb body is provided with a sliding cavity corresponding to the sliding portion, and the rack is slidably arranged in the sliding cavity through the sliding portion.

[0013] By adopting the above technical solution, the sliding part design can improve the sliding smoothness between the rack and the side wall of the sliding cavity of the hair straightening comb body, thereby preventing the utility model from getting stuck during operation.

[0014] The utility model is further configured as follows: the elastic reset member is configured as a tension spring, one end of the tension spring is fixedly connected to the rotating shaft corresponding to the second gear, and the other end of the tension spring is connected to the sliding portion through a pin shaft.

[0015] By adopting the above technical solution, when the cap is adsorbed and closed on the magnetic adsorption part on the side of the straight hair comb, the tension spring is stretched to accumulate elastic potential energy. When the cap is removed from the magnetic adsorption part on the side of the straight hair comb, the tension spring releases the elastic potential energy and drives the rack to automatically reset.

[0016] The utility model is further configured as follows: a guide plug-in portion is provided at one end of the rack, a avoidance hole is opened on the hair straightening comb body corresponding to the guide plug-in portion, and the guide plug-in portion is guide-plugged and matched with the avoidance hole.

[0017] By adopting the above technical solution, the addition of the avoidance hole increases the sliding stroke of the rack on the hair straightening comb body, which can effectively reduce the vertical length of the hair straightening comb body.

[0018] The utility model is further configured as follows: the hair straightening comb comprises a mounting plate and a comb tooth structure fixed on the mounting plate, and the steam outlet gap is provided between the mounting plate and the hair straightening comb body.

[0019] The utility model is further configured as follows: the comb tooth structure comprises a soft comb tooth group vertically arranged along the length direction of the mounting plate and a hard comb tooth ring surrounding the soft comb tooth group.

[0020] By adopting the above technical solution, the comb tooth structure with soft inside and hard outside can effectively improve the user experience when combing.

[0024] By adopting the above technical solution, when pushing the toggle switch to switch between the on and off states, the elastic member is reciprocatingly compressed and released, pushing the positioning ball to jump up and down between adjacent positioning grooves, effectively improving the feel of the toggle switch of the utility model when being toggled.

[0025] In summary, the utility model has the following beneficial effects:

[0026] The magnetic adsorption parts are symmetrically arranged on both sides of the straight hair comb body for magnetic adsorption with the magnets of the cap. When the device is in use, the cap is adsorbed on the magnetic adsorption part on the side of the straight hair comb head to achieve a dust-proof effect. When the device is in a shutdown state, the cap is adsorbed on the magnetic adsorption part on the side away from the straight hair comb head. The magnetic adsorption not only makes it more convenient to cover the cap, but also effectively prevents the cap from being easily lost after use. When the cap is adsorbed on the magnetic adsorption part on the side of the straight hair comb head, the cap pressing part pushes the first gear to rotate counterclockwise, and the first gear drives the second gear to rotate clockwise, and finally drives the rack to move downward. At this time, the locking part at the lower end of the rack is locked with the lock groove of the toggle switch in the closed state, so that the toggle switch is difficult to toggle to open, which can prevent the user from misoperating the cap in the closed state to cause the device to start, so that the utility model has the effects of preventing misoperation in the storage state, preventing dust and pests, and being easy to operate.

[0044] The basic working principle of the utility model is as follows: when the user uses the utility model, the cap 4 adsorbed on the side of the straight hair comb 3 is separated from the magnetic adsorption part 12 on the corresponding side of the straight hair comb body 1, and then the cap 4 is adsorbed on the side of the straight hair comb body 1 away from the straight hair comb 3 by using the magnetic adsorption force between the magnet 41 of the cap 4 and the magnetic adsorption part 12 on the other side, and then the steam combing operation can be performed by using the utility model. The magnetic adsorption of the utility model not only makes it more convenient to cover the cap 4, but also effectively prevents the cap 4 from being easily lost after use; when the user finishes using the utility model, the toggle switch 13 is toggled to the off state, at this time, the cap 4 is adsorbed on the magnetic adsorption part 12 on the side of the straight hair comb 3, so that the straight hair comb 3 is accommodated in the accommodating groove 4a of the cap 4, and the sealing effect of the cap 4 can effectively isolate external dust and prevent dust from falling on the straight hair comb 3. In addition, when the cap 4 is closed, the cap 4 is closed. When the cover 4 is closed on the hair straightening comb 3, the cover cap 4 will act on the pressing portion 141 to move, thereby linking the pressing and locking mechanism to actuate, and finally driving the locking portion 161 to lock in the locking groove 13a of the toggle switch 13. In this process, the elastic reset member accumulates elastic potential energy, and the locking and positioning effect of the locking portion 161 and the locking groove 13a makes it difficult to toggle the toggle switch 13 to open, which can prevent the user from misoperating the cover cap 4 in the closed state and causing the device to start. When the device needs to be used again, the cover cap 4 needs to be removed from the magnetic adsorption portion 12 on one side of the hair straightening comb 3 first, so that the pressing force of the cover cap 4 on the pressing portion 141 is eliminated. At this time, the elastic reset member releases the elastic potential energy and pulls the locking portion 161 away from the locking groove 13a, so that the toggle switch 13 is in the released position, and then the user can toggle the toggle switch 13 to the open state, so that the utility model has the effects of preventing misoperation, dust and insect prevention, and convenient operation in the storage state.

[0045] The above description is only a preferred embodiment of the present utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the scope of the present utility model patent application.
