Description

Electrothermos

The utility model belongs to a kind of electric-heating thermos, particularly a kind of architecture advances of small portable electric-heating thermos.

Present existing electric-heating thermos, most air pressure water flowing out structure that adopt, this structure more complicated also is out of order during use easily, and its bottle cap and delivery port sealing are relatively poor, and during the bottle overturning, water can release, thereby can only fixed placement.

The purpose of this utility model is the problem that exists at above-mentioned electric hot water bottle, proposes a kind of usefulness and manually controls effluent switch, and switch flexibly and good airproof performance is applicable to the electric water boiler of portable bath.

The purpose of this utility model is achieved by following examples.

Accompanying drawing 1 is the bottle cap stereogram of this electric hot water bottle;

Accompanying drawing 2 is the bottle perspective view of this electric hot water bottle;

Accompanying drawing 3 is the structure cutaway view of this electric hot water bottle.

The structure of this electric hot water bottle comprises bottle 3 and 1 liang of part of bottle cap, and bottle cap 1 is by the bottleneck of helical structure capping bottle.Individual inner pressurd vessel 4 is arranged in the bottle 3, in a side of bottle handgrip 6 is arranged, there is delivery port 5 on bottle top over against the opposite side of handgrip, and electric heating and temperature preservation control device 27 are installed in the bottom of bottle.Cover 19 in having in the said bottle cap 1, the outer peripheral face of interior cover 19 has spiral to cooperate with the inner peripheral surface of bottleneck, there is its afterbody to have the push rod 16 of return compression spring 18 in the interior cover, this push rod passes the spool 17 of its afterbody bifurcated, and the inclined-plane by push rod promotes spool and moves up and down, the lower end of spool 17 is air chamber covers 23, this air chamber cover and spool 17 are into a single integrated structure, air chamber cover is the valve between inner pressurd vessel 4 and the air chamber 20 that leads to delivery port 5, its marginal belt air chamber sealing ring 22, can seal up the edge of air chamber mouth well.In the below of cover 19 are the glands 26 that have the limbers, this gland is supporting the return spring 24 of air chamber cover, a gland ring 21 also is being with at the edge of gland, when screwing bottle cap, gland ring 21 is sealed the edge of bottle inner pressurd vessel 4.Has a water outlet button 7 on the top of said handgrip 6, a clutch shaft core 10 that places among the fixed muffle 11 is arranged in the water outlet button, the head big envelope of this clutch shaft core clutch sleeve 9, compression spring 12 is housed between clutch shaft core 10 and the fixed muffle 11, fixed muffle 11, clutch sleeve 9, clutch shaft core 10 and compression spring 12 constitute the clutch of water outlet button, when bottle cap was screwed, the afterbody of clutch shaft core faced the head of push rod 16 and it can be promoted.

Above-mentioned several movable agency comprises spool 17, push rod 16, clutch shaft core 10, is with sealing ring 25,15,13 respectively in the joint portion of itself and miscellaneous part, thereby has increased the sealing of this electric hot water bottle.

The bottle cap 1 of this electric hot water bottle has a cantilever 2, when screwing bottle cap, makes the bottom surface of cantilever 2 align the end face that is adjacent to handgrip 6, and align and cover anchor point, the afterbody of clutch shaft core 10 just aligns the head of push rod 16, can press by water outlet button 7, makes delivery port be in water state or sealing state.

For making the user understand the residing on off operating mode of delivery port intuitively, a display window 8 is arranged in the side of handgrip, when water outlet button 7 when pushing state, the sidewall of water outlet button has one " going out " word to show on display window, at this moment the clutch shaft core 10 on the button is with push rod 16 jackings, spool 17 is depressed on the inclined-plane of push rod 16, and then open air chamber cover 23, owing to have to the limbers of inner pressurd vessel 4 on the gland 26 below the air chamber cover 23, make delivery port 5 become connected state to inner pressurd vessel again, thereby electric hot water bottle is in water state to air chamber 20; When again by water outlet button 7, the clutch of water outlet button recoils to reset mode to the water outlet button, the sidewall of water outlet button has one " ending " word to show on display window, at this moment, because 10 withdrawals of clutch shaft core, push rod 16 is return under the effect of push rod return spring 18, and the inclined-plane of push rod withdraws from the ejection to spool 17, spool 17 together with air chamber cover 23 the effect of air chamber cover return spring 24 next time closedtop live the air chamber mouth, thereby electric hot water bottle is in the sealing state.

The utility model break-make of the clutch structure control delivery port of water outlet button, the switch of water outlet is flexible, and each relevant parts all has good seal approach, also can not release during the electric hot water bottle overturning.This electric hot water bottle is simple in structure, and is for ease of maintenaince easy to use, is specially adapted to make the small portable electric hot water bottle.

The component names that other several labels are corresponding among the figure is respectively: supply socket 28, boiling indicator lamp 29, insulation indicator lamp 30.
