Description

Lead static comb

Technical field

The utility model relates to a kind of comb, especially a kind ofly can lead the comb that destatics.

Background technology

When using insulation combs such as existing wooden comb, plastic comb or horn comb to comb one's hair as people; Friction between comb and the head will make electrostatic charge on hair, the comb band; Even take place between comb and the hair and hair static discharge phenomenon each other; Hair also is easy to knotting except floating up, and is difficult to combing.In the course of time, this static discharge phenomenon also might cause withered and yellowish hairs, alopecia, influence serious consequences such as brain health.

Developed the comb of some antistatics.Like Granted publication number is the Chinese patent of CN2272683Y; Disclose a kind of no static health-care comb, comprised metal comb, down conductor and grounding body, comb is connected with grounding body through down conductor; Grounding body can adopt running water pipe or grounded metal of ground connection etc.; When combing one's hair, the electrostatic charge that produces because of friction between comb and the hair imports in the ground via down conductor, makes comb, hair remain zero potential.

Yet, this no static comb, running water pipe through ground connection or grounded metal etc. are ground connection directly; Comparatively inconvenient during use; In addition, not only ground connection is unreliable, and is easy to make grounding body charged for various reasons; The safeguard measure that have no owing to comb this moment, thus can damage the user.

The utility model content

The utility model technical problem to be solved provides a kind of static comb of leading, and through the threshold currents protection is set, can the electrostatic charge that comb produces be imported the earth reliably, and guarantee user's safety.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of static comb of leading, comprise comb head and comb handle, and said comb head is connected with the earth connection metal terminal through conductor wire, it is characterized in that, and said conductor wire is provided with current-limiting apparatus.

According to an embodiment of the utility model, said current-limiting apparatus is a resistance, and said resistance and said earth connection metal terminal are arranged in the ground pin.

Alternately, said current-limiting apparatus is a resistance, and said resistance is arranged in the said comb handle, and said earth connection metal terminal is arranged in the ground pin.

Preferably, said resistance is metalfilmresistor, because of its failure mode is obstructed, thereby safe and reliable, and the metalfilmresistor long service life, make that the service life of leading static comb is longer.

Breakdown voltage resistant＞the 380V of said resistance, current limit guarantee that thus the electricity of earth connection metal end subband can not damage human body under the situation that ground connection makes mistakes below 10mA.

After preventing long-time the use,, also be provided with fusible link or the fuse of current limit≤30mA on the said conductor wire if the failure mode of resistance can't not play effective metering function for opening circuit.

According to another embodiment of the utility model, said current-limiting apparatus is fusible link or fuse, and said fusible link or fuse and said earth connection metal terminal are arranged in the ground pin.

Alternately, said current-limiting apparatus is fusible link or fuse, and said fusible link or fuse are arranged in the said comb handle, and said earth connection metal terminal is arranged in the ground pin.

For under the situation that prevents the earth connection wrong human body being damaged the current limit≤30mA of said fusible link or fuse.

Said comb head comprises end plate of being processed by conductor or semiconductor and the broach main body that is fixed on the broach on the said end plate; The electrostatic charge that produces at first is directed to conductor wire via broach main body and end plate; The end of said broach is provided with the hair comb head of insulation, with further reinforced insulation protection.

Compared with prior art, the advantage of the utility model is: between conductor wire and earth connection metal terminal, be provided with current-limiting apparatus, like resistance or fusible link or fuse, prevent when ground connection is made mistakes that comb is charged and human body is damaged; Ground pin can be inserted into general socket and connect the earth, and is not only easy to use but also make ground connection reliable.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Referring to Fig. 1,, comprise the comb handle 2 of comb head 1 and insulation according to an embodiment who leads static comb of the utility model.Comb head 1 comprises end plate 11 and is fixed on the broach 12 on the end plate 11.The broach main body 121 of end plate 11 and broach 12 can be processed by conductor or semiconductor, and 122 of the hair comb heads of broach 12 ends are processed by insulating materials.

End plate 11 is arranged in the end of comb handle 2, and an end of end plate 11 is connected with conductor wire 3, and the other end of conductor wire 3 connects ground pin 4.Ground pin 4 comprises insulation shell 41, preferably, is made of plastics; Be provided with resistance 42 in the ground pin 4, play the effect of current limliting, with the earth connection metal terminal 43 that is connected with resistance 42; Resistance 42 also is connected through conductor wire 3 with earth connection metal terminal 43, the conductor wire 3 outer insulating materials that coat.Preferably, be metalfilmresistor, its stable performance is safe and reliable, can reach service life more than 10 years,

Referring to Fig. 2, according to another embodiment that leads static comb of the utility model, the difference of itself and the foregoing description is that resistance 42 is arranged in the comb handle 2.

During use; Can ground pin 4 be inserted in the general socket; This makes that use is comparatively convenient; Broach 12 is transferred to conductor wire 3 with a fricative electrostatic charge through end plate 11 in the process of combing one's hair, and inserts the earth electrostatic charge of releasing by conductor wire 3 through resistance 42 and earth connection metal terminal 43 again, thereby has prevented electrostatic hazard.

When Outlet line circuit wrong, earth connection metal terminal 43 can be therefore and charged (220V or 380V) in this case, need guarantee that still the user is in a safe condition, and prevents that power current from damaging human body.Breakdown voltage resistant needs＞the 380V of resistance 42; And the electric current that under 380V voltage, is passed through must satisfy people's physical efficiency let-go current (in general, when the following power current of 10mA flow through human body, the people can let-go current); And the failure mode of preferred metalfilmresistor is obstructed, promptly opens circuit.After long-time use, because the breakdown voltage resistant of other form resistance 42 can descend, its failure mode maybe be for not opening circuit; For guaranteeing user's safety; At this moment, fusible link or the fuse 44 of current limit≤30mA can be set on conductor wire 3, as shown in Figure 3.

Referring to Fig. 4; According to another embodiment that leads static comb of the utility model, itself and Fig. 1 or embodiment difference shown in Figure 2 are that in this embodiment current-limiting apparatus is fusible link or fuse 44; User's safety during for assurance Outlet line circuit wrong, current limit≤30mA.

The above is merely the preferred implementation of the utility model; Should be pointed out that for those of ordinary skill in the art, do not breaking away under the principle prerequisite of the utility model; Can also make various deformation and improvement, this also should be regarded as the protection domain of the utility model.
