Abstract
The utility model discloses a short circuit proof socket plug combination for a water collecting electric heater, belonging to the household appliance technical field. The combination consists of a plug (1), a socket (2), a water blocking rubber gasket (6), a socket baffle (17), a connecting rod (7), a spring (9) and a lock catch combination. The structure of the lock catch combination comprises a lockhole (10), a locking bar (11) and a cylinder (12). When the heater is electrified to heat, a socket body (3) is exposed from an electric appliance housing (8), and the water blocking rubber gasket (6) is pressed tightly against an inner wall of the housing (8). When the locking bar (11) is inserted into the lockhole (10), the front end of the socket (2) flushes with an outer wall of the water collecting electric heater housing (8).

The combination is special in design, novel in appearance, simple and convenient in operation, and does not disturb packaging and putting.
Description
Technical field
The utility model belongs to the technical field of household electrical appliance, particularly is used for the socket plug combination of electric heater.
Background technology
The electric heater that is filled with water described in the utility model is meant electrical equipment such as electric heating pot, electric rice cooker (pot), electric heating kettle.
The Circuits System of the existing electric heater that is filled with water is connected the plug of power line one end by power line, is installed in the electrothermal device (as electric furnace heating wire, Electric radiant Heating Film etc.) in the electric heater that is filled with water, and the socket that is electrically connected with electrothermal device constitutes.Generally, plug is made by duroplasts, and 2～3 metal jacks are arranged on it, and 2～3 leads that are connected with jack are electrically connected with attaching plug by power line, and attaching plug is used to connect the 220V power supply; Socket then is installed in the shell of the electric heater that is filled with water, and the front end of jack body has inside opening, and opening profile with plug on shape and yardstick is corresponding; Be electrically connected electrothermal devices by 2～3 metal mandrels that are embedded in the duroplasts jack body, the number of metal mandrel and position are then corresponding with the number and the position of jack in the plug,, constitute the combination of plug-in socket plug that is; This socket plug is used in combination in single-phase electricity, and the 3rd metal mandrel and jack are used for ground connection.
Socket plug combination on the existing electric heater that is filled with water, socket embeds in the shell of the electric heater that is filled with water, and its front end and shell are not given prominence to outside shell on same vertical plane, and this is not only attractive in appearance in appearance, packs or puts nor hinder.But, when heating or boiling food, often there are water or thin rice gruel or vegetable soup to flow out, and flow in the socket along the shell shell wall of the electric heater that is filled with water, cause short circuit between metal mandrel, cause electric leakage, burn out electrical equipment, even cause the situation of fire and the burn electricity person of hurting sb.'s feelings.
The utility model content
The technical problems to be solved in the utility model is the anti-short circuit socket plug combination of design, overcome prior art because the shortcoming that water that overflows or soup are easy to cause short circuit.
For reaching the purpose of anti-short circuit of the present utility model, concrete technical scheme is:
Anti-short circuit socket plug combination on a kind of electric heater that is filled with water, structure has plug 1,2～3 metal jacks that are electrically connected with power line are arranged in the plug 1,, 2～3 metal mandrels 4 that are electrically connected with electrothermal device in the electric heater that is filled with water are arranged in the jack body 3 with the supporting socket 2 of plug 1; It is characterized in that lateral surface is equipped with water blockoff rubber blanket 6 in the rear end of jack body 3, the front end lateral surface of jack body 3 is equipped with socket baffle plate 17; Being connected as a single entity of connecting rod 7 and jack body 3 coaxial lines arranged in the rear end of jack body 3; At connecting rod 7 be filled with water and between electric heater shell 8 inwalls spring 9 be housed, the elastic force direction of spring 9 is identical with the axis direction of jack body 3; The snap close combination is housed in the electric heater that is filled with water, and the snap close combination is made up of locking bar 11, lockhole 10 and cylinder 12, and locking bar 11 is contained on the connecting rod 7 or in the cylinder 12, lockhole 10 is opened on cylinder 12 or connecting rod 7.
During use, plug 1 is inserted socket 2, flicking socket 2 front ends make spring 9 that compression be arranged slightly, make locking bar 11 break away from lockhole 10, under spring 9 effects, automatically socket 2 is ejected, jack body 3 is exposed outside the electric heater shell 8 that is filled with water, this moment jack body 3 the water blockoff rubber blanket 6 that is equipped with of the rear end lateral surface inwall of electric heater shell 8 of being filled with water that reclines, energising work.During end-of-job, cut off the power supply and pull up plug 1, socket 2 is compressed in the electric heater that is filled with water, when jack body 3 front ends are equal with the electric heater shell 8 of being filled with water, make locking bar 11 insert lockholes 10, socket 2 is locked in the electric heater that is filled with water.
When being filled with water electric heater work, because socket 2 protrudes in the shell 8 of the electric heater that is filled with water, water blockoff rubber blanket 6 tightly abuts in the inwall of the electric heater shell 8 that is filled with water under spring 9 effects, even have water or soup inwardly to flow to the binding site of shell 8 and socket 2, also can not enter in the electric heater that is filled with water; Because socket baffle plate 17 is equipped with in jack body 3 front end sides, even have water or soup outwards to flow to the front end of socket 2, has the retaining of socket baffle plate 17 to cut, water or soup also flow less than in the space between socket 2 and the plug 1.When the electric heater that is filled with water is not worked, snap close combination can be retracted within the electric heater shell 8 that is filled with water by locking receptacles body 3, can also block jack body 3 unlikely complete retractions at the socket baffle plate 17 that the front end lateral surface of jack body 3 is equipped with and be filled with water in the electric heater.Like this, still can make good looking appearance, also not hinder and pack or put.
The beneficial effects of the utility model are, solved the harm that the electric heater product plugs and sockets that is filled with water on the current market is easily intake and had an accident, given up the fear of people, promoted people the purchase of this series products and courageously use to the electric heater leak electricity short-circuit that is filled with water; Design is unique, outward appearance is novel; Easy and simple to handle, need not keep constantly in front of the electric heater that is filled with water, because water that overflows or soup thoroughly are blocked in outside the danger.
