Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of temp sensing controller, shown in Fig. 1～4.Wherein, the cross-sectional view of the temp sensing controller that provides for the utility model embodiment of Fig. 1; Fig. 2 is the vertical view of temp sensing controller shown in Figure 1; Fig. 3 is the explosive view of temp sensing controller shown in Figure 1; Fig. 4 is the upward view of temp sensing controller shown in Figure 1.In above-mentioned Fig. 1～4,1 is main casing, and 2 is conducting strip, and 21 is moving contact, and 22 is extension, and 3 is static contact, and 31 is fixed contact, and 4 is swingle, and 5 is spill spin block, and 6 is the elastic return part, and 7 is toroidal cavity, and 71 is the toroidal cavity outer.
With reference to Fig. 1～4; The temp sensing controller that the utility model embodiment provides; Comprise main casing 1, conducting strip 2, static contact 3, swingle 4, spill spin block 5 and elastic return part 6; The toroidal cavity outer 71 of above-mentioned main casing 1 is provided with groove (particular location of this groove confirms that by the position of conducting strip those skilled in the art can confirm the position of this groove according to the purpose of present embodiment), and the lower end of above-mentioned swingle 4 is installed in the above-mentioned groove; The upper end of swingle 4 is connected with the upper end of spill spin block 5, and the lower end of spill spin block 5 is connected with the two ends of elastic return part 6 respectively with swingle 4; Swingle 4 than spill spin block 5 more near the center of circle of toroidal cavity;
Conducting strip 2 is provided with the extension 22 that extends to the side, and extension 22 is positioned at an end at moving contact 21 places of conducting strip 2, and forms bad angle, and above-mentioned swingle 4, spill spin block 5 and elastic return part 6 are positioned at this bad angle; At the end of travel of spill spin block 5, moving contact 21 separates (being that power supply breaks off), the lower end of spill spin block 5 and extension 22 butts with the fixed contact 31 of static contact 3.
The operation principle of the responsive controller of said temperature is following:
When connector inserted in the toroidal cavity 7 of temp sensing controller main casing 1, connector promoted swingle 4 and moves, make its to spill spin block 5 near, elastic return part 6 is compressed; Under the elastic force effect of elastic return part 6, spill spin block 5 moves with swingle 4 in the same way, and the extension 22 of the conducting strip 2 in being positioned at spill spin block 5 strokes blocks, and elastic return part 6 is in compressive state at this moment.
Water is boiled in insulating pot; When the temperature of temperature-sensitive bimetal leaf rises to above set point; The temperature-sensitive bimetal leaf produces kick, deformation promptly takes place, downwarping; Downward deformation takes place in an end that is provided with extension 22 that promotes conducting strip 2 through the power-assist porcelain rod that is positioned at its below, and moving contact 21 and fixed contact were opened in 31 minutes; Simultaneously; Because extension 22 with the deformation of conducting strip 2 downward displacement has taken place, make extension 22 no longer in the stroke of spill spin block 5, so spill spin block 5 no longer receive extension 22 and stop; And then under the elastic force effect of elastic return part 6; Continue to move to its end of travel, make extension 22 be positioned at its below, promptly spill spin block 5 blocks extension 22.
Temperature decline when the temperature-sensitive bimetal leaf; When deformation recovers, though the power-assist bar magnet can not apply downward thrust to conducting strip 2 again, because spill spin block 5 blocks extension 22; No matter whether movement arm can rotate; Conducting strip 2 all can not recover deformation automatically, and moving contact 21 can not contact with fixed contact 31 again, promptly can not recover to make electric current to connect automatically again because of the deformation of temperature-sensitive bimetal leaf.
Have only after connector is extracted in the toroidal cavity 7, because connector is no longer to the swingle applied thrust, so under the elastic force effect of elastic return part 6; Swingle 4 oppositely moves; Get back to the position before connector inserts, spill spin block 5 also resets thereupon, makes conducting strip 2 no longer be stuck.Like this, all parts of the described temp sensing controller of the utility model embodiment extracting and reset all with connector.
Can find out by foregoing description; The temp sensing controller that the utility model embodiment provides; After the temperature-sensitive bimetal leaf produces kick; Promote conducting strip through power-assist porcelain rod and produce downward deformation, spill spin block move under the elastic force effect of elastic return part conducting strip above, connect with the extension of conducting strip; When temperature-sensitive bimetal leaf Yin Wendu descends and recovery deformation; When no longer power-assist porcelain rod being applied downward motive force; No matter whether movement arm can rotate, and conducting strip all because of being hindered and can not reset by the spill spin block of its top, has been avoided the phenomenon of power supply circulation break-make; And then avoided the property loss and the personal injury that cause because of the too high generation booster of insulating pot heat-generating pipe temperature, improved the security performance of insulating pot.
Further, referring to Fig. 5, the lower end of the spill spin block 5 in the foregoing description is provided with jut 51, and when spill spin block 5 moved to its end of travel, jut 51 connected with extension 22, promptly through jut 51 conducting strip 2 is blocked.
Further, the function of the elastic return part among above-mentioned all embodiment can realize through compression spring or spring leaf.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
