Abstract
The utility model relates to a power-source automatic control device for electrically heating thermoses. The utility model is characterized in that the inner cavity of a main body has a conjugation hole; the conjugation hole has fixed plastic; the place between the fixed plastic and the inner cavity has a waterproofing pad; the fixed plastic is connected with two probing rods to probe the height of water level. The utility model can cut power supply automatically when the water level in a thermos is too low to prevent accidents, such as a fire generated by the empty heating of the thermos through a control device according to the result of the water level probed by the probing rods.
Description
The utility model is an electric hot water bottle power supply self-con-tained unit, and being provides electric hot water bottle when water level is not enough, can cut off the power supply automatically, belongs to the commodity auxiliary equipment.Electric hot water bottle has only level displaying device, but level displaying device often reduces because of angle, light problem are difficult for discovering water level, or user itself ignores, and causes water to use up and do not know, causes electric hot water bottle to continue empty the burning, and causing electric hot water bottle to burn, waste electric power very causes and causes fire.
The main purpose of the utility model, tying up to provides an electric hot water bottle power supply automaton, when water level in the electric hot water bottle is crossed when low, can be automatically dump.
The utility model is a kind of electric hot water bottle power supply automaton, be one conjugate foramen to be arranged by thorax in the main body, this conjugate foramen has a fixing plastic cement, fixedly plastic cement and interior thorax have a waterproof gasket, fixedly plastic cement is connected to two detector bar sensing water levels height, according to detector bar sensing water level height result, see through a control device, make the power supply automaton.
Now lift a preferred embodiment and cooperate graphic being illustrated in down:
The part three-dimensional exploded view of Fig. 1 the utility model embodiment.
The control device circuit diagram of Fig. 2 the utility model embodiment.
See also shown in Figure 1, a kind of electric hot water bottle power supply of the utility model self-con-tained unit, system comprises a main body (1), one sensing apparatus (2) and a control device (3) (shown in Figure 2), this main body comprises a thorax (11) and a conjugate foramen (12) in one, above-mentioned sensing apparatus (2) comprises a fixing plastic cement (21), two detector bars (22) (23), two circular hollow pads (24) (25), one conjugant (26), fixedly plastic cement (21) car has pin thread (211), and inside is provided with microscler aperture (214) (215), should be fixedly plastic cement (21) pass pad (24) ecto-entad and lock conjugate foramen (12) and connect airtight with it, has the waterproof effect that leaks outside, pad (25) is set in fixedly plastic cement (21) the inner, and the interior car of above-mentioned conjugant (26) has negative thread (261), lock fixedly within the plastic cement (21) end and pad (25) and in thorax (11) connect airtight, make the waterproof function that leaks outside more effective, fixedly plastic cement the inner is provided with one and is bent upwards the water-stop sheet (212) that slightly is arcuation, this water-stop sheet (212) is between two detector bars (22) (23), prevent that water level is just between break-make, because of the boiling of water or rock etc., and cause intermittent energising, fragile circuit, and there is a little osculum (213) in water-stop sheet (212) central authorities, and anti-sealing amasss on water-stop sheet (212); Above-mentioned detector bar (22) (23) pin thread (221) (231) of having got on the bus, this two detector bar (22) (23) ecto-entad is locked two apertures (214) (215) that fixing lock glue (21) is gone up, arrive main body (1) inside, the sensing water level is height, and two detector bars (22) (23) outer end connects a control device (3) again, and it is shown in Figure 2 that being described in more detail of this control device (3) consulted.Supply voltage AC110V or AC220V, produce an AC12V by transformer (31), pass through electronic building brick (32) again and produce DC12V, when water level is higher than detector bar (23), relay (33) ON then, switch (34) ON, switch (35) OFF, electric hot water bottle do heating or insulation action, when water level is lower than detector bar (22), relay (33) OFF, this moment, switch (34) OFF stopped heating or insulation action, switch (35) ON, anhydrous indicator lamp (36) ON waits for the water source that reinjects, and reaches anhydrous automatic outage.
Major advantage of the present utility model ties up in electric hot water bottle water level and crosses when low in sum, can automatic cut-off power, and preventing that electric hot water bottle is empty burns so that burns, and plays the safeguard protection effect in the electric hot water bottle use procedure.
The number in the figure explanation:
1. main body 2. sensing apparatus 3. control device
11. interior thorax 12. conjugate foramens 21. are plastic cement fixedly
22,23. detector bars, 24,25. pads, 211. negative and positive screw threads
212. water-stop sheet 213. osculums 214,215. microscler apertures
221,231. negative and positive screw threads, 31. transformers, 32. electronic building bricks
33. relay 34,35. switches 36 anhydrous indicator lamps
Claims (2)
1, a kind of electric hot water bottle power supply self-con-tained unit, it is characterized in that: it is to establish a conjugate foramen by thorax in the main body, and this conjugate foramen connects a fixing plastic cement, and this fixedly is connected to a waterproof gasket between plastic cement and interior thorax; Should fixedly be connected to two detector bars on the plastic cement, this detector bar is provided with screw thread, is connected to control device in its outer end, and fixedly plastic cement the inner is provided with a water-stop sheet that is bent upwards, between two detector bars.
