Abstract
The utility model relates to a boiling switch for an electric heating disk type electric cup; and the boiling switch comprises a shell. The top of the shell is arranged with a rocker bar, and a steam chest under the shell is arranged with two disc-shaped metal sheets fit with the rocker bar. An electric on-and-off chamber of the shell is internally provided with an upper contact sheet and a lower contact sheet. When water is boiled in the electric cup, steam enters the steam chest to wash out the two metal sheets and cause the heave motion of the two metal sheets. The tapered necking of the rocker bar is pushed to make the rocker bar sway upward, at the same time, the upper contact sheet is lifted by a T-shaped pull rod lifts, and the two dynamic contact points get isolated to cut off the power supply. For the secondary heating, the reposition of the rocker bar can be made by manual operation. Components of the utility model have stable and reliable actions, and the reasonable clearance is made between electric appliances. Besides, the section of materials for key components and the processing technique are done rationally. The service life of the utility model is lasted for a very long time.
Description
Technical field
The utility model relates to the electric water-heating cup parts of no visible electrothermal tube in a kind of cavity volume, but especially relates to a kind of electric heating disk type electric water-heating cup boiling switch of hand-reset.
Background technology
The electric water-heating cup boiling switch, for the electric water-heating cup of visible electrothermal tube in cavity volume, boiling switch and overtemperature protection system all install on an elongated substrate on the market, adopt the bimetal leaf actuating of being with tongue in the middle of the disc of different temperatures level.And for the electric heating disk type electric water-heating cup; the kind of its boiling switch mainly contains two kinds; a kind of is disclosed as CN1294894A; it is the product that Britain executes Trikonex AB; its boiling level bimetal release and overtemperature protection system bimetal leaf all are arranged on the water tumbler bottom, and steam is incorporated into boiling level bimetal leaf from the cup top by small pipeline and causes outage.It also can manually reset, and finishes by load maintainer and escape lever.Another kind is the irreversible boiling switch of Britain Otter company design, it as an assembled in electric heating disk type electric water-heating cup handle body, rectangle bimetal leaf of steam flush is upspring bimetal leaf and is thrown off power supply, also can hand-reset, but, the rectangle bimetal leaf is more because of area consumes energy greatly, and action sensitivity is not good enough, and the lug of stirring on its swing rocking bar top has only one grade, after manual pendulum knob assembling, can produce one section excessive neutral gear stroke during promotion; Set adjustable column brings inconvenience in the use to the people easily, and as the fastener cone angle of supporting and the interior cone angle of housing, it is too small that angle differs during the rocking bar swing, and the wobbling action that often has influence on rocking bar puts in place.
Summary of the invention
The utility model mainly is that solution existing in prior technology structure is very unreasonable, and the parts wobbling action is understable, the very reliable technical problem that waits of general safety performance.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: comprise housing, be provided with rocking bar above the housing, be provided with butterfly shaped dual metal sheet in the following vaporium with described rocking bar phase configuration, indoor contact and the following contact of being provided with of the power on/off of housing, be provided with the arc section that radius is Ri in the described housing, it is indoor that its surface is in power on/off, and the center line of the center line of described upper contact head and following contact and the lug of rocking bar apart
On the described housing, the support slot of the supporting head of supporting below the rocking bar is apart from its lower plane H=1.5-2.5mm.The place that arc section is vacated below just can be provided with T character-shaped pull bar and last contact, the position of electrical contact is also correspondingly close to arc section, such position makes after the bimetal leaf action, contact in the pull-up of T character-shaped pull bar, the electric clearance of the upper and lower contact on the contact can reach 2mm, reach the regulation of standard GB 4706.1-98 the 29.1st, thereby eliminated the hidden danger of arc.
As preferably, the described contact of going up is by standing part and swing part phase-splitting riveted joint, wherein standing part is a brass 62, thickness is 0.8mm, and the leading portion swing part adopts beryllium-bronze to constitute, and through Ageing Treatment, make it to have the spring steel mechanical performance, stable contact pressure between two contacts is provided, reduces contact resistance, indefatigability again.The thickness of last contact swing part is 0.2mm, and its leading section is provided with a breach, is nested with on the T character-shaped pull bar below described rocking bar.Even after going up contact fatigue like this, can not deviate from yet, improve the general safety performance.
As preferably, described rocking bar is arranged on the housing by support spring, and described support spring is a planar rectangular, thickness is 0.2mm, adopts 3 chromium 13 to constitute, and adds tempering through quenching and handles, its length is greater than two end supports point air line distance 2.5mm, and a strong point is a V-arrangement, and another strong point is a circular arc.Support spring is through the cooling of 660 ℃ of tempering oils of 1000 ℃ of oil quenchings, to solve to steam problem such as antirust and mechanical fatigue.After the support spring assembling, be differential of the arc shape, the making a concerted effort of counter-force counter-force substantially all acted on the rocking bar basically by the center of bar.Because support spring needs swing, a strong point is a V-arrangement, another strong point is that the structure of circular arc comparatively meets mechanics principle, and form two subtriangular, be triangle fixed support point, the upper strong point, supporting point and triangle fixed support point, the next strong point, supporting point, thereby form size two arm of forces of L1, L2 greater than 3.5mm, counter-force P * L=M moment makes rocking bar stable two extreme position self-lockings.
As preferably, the obverse and reverse of the upper end of described rocking bar respectively is provided with two semicircular lugs, because lug and fork on the electric water-heating cup part pendulum button are to contact, two lugs are line contacts, two lugs are set, have reduced the neutral gear stroke, action sensitivity is improved.It is conical nose cone that the bottom is provided with solid near bimetal leaf one side, and cone headed working temperature is very high, and cone is not yielding.Cone headed opposite is provided with the circular arc supporting head, the little 0.5mm of support slot arc radius on its radius ratio housing; The back body cone angle of described supporting head is than the little 12-15 degree of opening angle of support slot.Supporting head is arranged to circular arc, and radius is a little bit smaller, can reduce specific pressure, can not lose shape for a long time in the locus.
As preferably, the thickness of described bimetal leaf is 0.3mm, and the radius of a ball of its concave surface is SR=64-66mm, and described bimetal leaf concave spherical surface is at a distance of nose cone 0.7-1.0mm.Here select for use have in the middle of the dish that is swift in motion of JB7133-93 or the dish tongue bimetal leaf, the radius of a ball of the concave surface of appropriate design bimetal leaf, can the safety action triggered time be 3-5 second.
Characteristics such as therefore, the utlity model has compact conformation, rationally distributed, the parts action is reliable and stable, and electric clearance is reasonable, and vitals selection and treatment process are reasonable, and useful life is long.
