Abstract
The utility model discloses a household electrical appliance safety protection structure, including a household electrical appliance housing. A safety switch carrier is arranged in the housing; the safety switch carrier is provided with a sensitive safety switch provided with an elastic arm; the safety switch carrier is provided with a driving rod which passes through the safety switch carrier; the driving rod can move between the housing and the elastic arm; when the housing is closed, the driving rod is supported against the elastic arm on the sensitive safety switch to close the contact; and when the housing is opened, the driving rod releases the sensitive safety switch to break the contact. In the utility model, the usage security of the electric appliance is enhanced under the precondition that the product cost is almost not increased, the safety switch in the electric appliance is controlled by the product housing, no other human management or additional material cost is required, and the household electrical appliance safety protection structure is convenient and reliable, and is a self-safety control design which is rare in electric appliances.
Description
Technical field
The utility model relates to a kind of electric switch structure, specifically, relates to a kind of safety protection structure that is used for the anti-dismounting electric leakage of household electrical appliance.
Background technology
Household electrical appliance have been come into huge numbers of families, with our daily life all close getting in touch are arranged.Some electrical equipment may be changed wherein parts in use to reach the purpose that recycles, like anti-mosquito incense sheet, and bulb or the like.If forget during dismounting that pulling out power supply cuts off the power supply,, cause serious casualties and property loss because problems such as internal wiring loose contact may injure human body even cause fire because of getting an electric shock.
Electronic product on the market generally can not done any Safety Design to the dismounting Danger Electric shock risk property of electrical equipment specially now, all is to prevent the potential safety hazard that electrical equipment causes through the mode that adds 3-phase plug usually.
The utility model content
The utility model will solve gets an electric shock easily when being the household electrical appliance dismounting or causes the technical problem of disaster hidden-trouble, and a kind of household electrical appliance safety protection structure rational in infrastructure, with low cost is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through following technical scheme:
A kind of household electrical appliance safety protection structure comprises it is characterized in that the shell of household electrical appliance, is provided with the safety switch carrier in the said shell, on the said safety switch carrier fine motion safety switch and drive link is installed; When said enclosure closed, said drive link is replaced and on the elastic arm of said fine motion safety switch, is made its closing of contact; When said shell was opened, the elastic arm that said drive link discharges said fine motion safety switch broke off its contact.
Said fine motion safety switch is the safety switch of 15A, 250V.
The beneficial effect of the utility model is:
The utility model is installed in the fine motion safety switch on the inner part of electrical equipment; The fine motion safety switch is connected with All other routes; The elastic arm of fine motion safety switch withstands on the another one driver member; Make it become control, add product casing at last, accomplish the automatic control of product casing folding the fine motion safety switch to the fine motion safety switch.After complete machine was accomplished assembling, the fine motion safety switch was closure state, because the closed power supply of fine motion safety switch is connected, user can freely use product during this.When complete machine needs repairing or inner body need change the time, open shell, the fine motion safety switch is in dissengaged positions, and power supply is disconnected, even do not pull out power supply, electrical equipment can not cause the threat of damage to human body yet.
The utility model has improved the safety in utilization of electrical equipment greatly under the prerequisite that increases product cost hardly; And the fine motion safety switch in the electrical equipment is controlled by product casing; Not needing separately, behavior adjustment management perhaps increases the other materials cost; Convenient and reliable, be rare design that can self-security control in the electrical equipment.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the cutaway view of the utility model.
Among the figure: 1: fore shell, 2: drive link, 3: fine motion safety switch, 30: elastic arm, 4: safety switch carrier, 5: mesochite.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe in detail:
To shown in Figure 2, present embodiment is an example with the clarifier, has disclosed a kind of household electrical appliance safety protection structure, can increase the household electrical appliance fail safe, causes electric shock when avoiding the dismounting machine like Fig. 1.Be provided with safety switch carrier 4 in the mesochite 5 of clarifier, through two screw fine motion safety switch 3 be installed on the safety switch carrier 4, fine motion safety switch 3 is electrically connected with All other routes.Fine motion safety switch 3 inside are the single-pole double throw contact structure, upspringing and depress the switching of accomplishing the contact through elastic arm 30.
Like this, when shell 1 closure, drive link 2 is replaced on the elastic arm 30 of fine motion safety switch 3 and is made its closing of contact; When shell 1 was opened, the elastic arm 30 that drive link 2 discharges fine motion safety switch 3 broke off its contact.
The utility model passes hole corresponding on the safety switch carrier 4 with drive link 2 earlier when assembling, fine motion safety switch 3 is installed on the safety switch carrier 4 again.After steadily fixing, safety switch carrier 4 is installed on the mesochite 5, microcephaly's one end of drive link 2 passes the guide hole on the mesochite 5 simultaneously, after each parts assembling is intact, installs shell 1 at last.Drive link 2 promoted and pushes up the elastic arm 30 of fine motion safety switch 3 inwards when shell 1 was in place, and made the closing of contact of fine motion safety switch 3, and electric power loop is connected.When clearing up or safeguarding that clarifier need be opened shell 1, the elastic arm 30 of fine motion safety switch 3 is released, and the contact is disconnected, and fine motion safety switch 3 breaks off the back electric power loops and is cut off.
Present embodiment can effectively avoid clarifier forgetting that pulling out the power line situation tears dangerous that the machine maintenance possibly cause open, makes human body avoid getting an electric shock and comes to harm.
Although combine accompanying drawing that the preferred embodiment of the utility model is described above; But the utility model is not limited to above-mentioned embodiment, and above-mentioned embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Not breaking away under the scope situation that the utility model aim and claim protect, can also make the concrete conversion of a lot of forms, these all belong within the protection range of the utility model.
Claims (2)
1. household electrical appliance safety protection structure; The shell that comprises household electrical appliance; It is characterized in that, be provided with the safety switch carrier in the said shell, the fine motion safety switch that elastic arm is set is installed on the said safety switch carrier; Be coated with drive link on the said safety switch carrier, said drive link can move between said shell and said elastic arm; When said enclosure closed, said drive link is replaced and on the elastic arm of said fine motion safety switch, is made its closing of contact; When said shell was opened, the elastic arm that said drive link discharges said fine motion safety switch broke off its contact.
