Abstract
The utility model relates to a temperature sensitive cup without pot protection, which comprises a shell, wherein a cup cover is covered on the shell, a cup seat is arranged in the shell, a thermistor is arranged on the cup seat, the lower portion of the shell is provided with a mounting seat, and an outer spring is supported between the shell and the mounting seat. A top rod is arranged on the mounting seat, the upper end of the top rod extends in the shell, and the upper end thereof is provided with a dynamic contact piece. A static contact piece which is matched with the dynamic contact piece is arranged in the shell, and the static contact piece is connected with the thermistor. The temperature sensitive cup without pot protection leads the dynamic contact piece and the static contact piece to match to act through sensing the gravity of an inner pot, thereby breaking and connecting the thermistor, and sending temperature signals to a chip to achieve whether heating. The temperature sensitive cup without pot protection always locates in a normally closed state when an inner pot vessel is not put, the dynamic contact piece and the static contact piece are connected with the thermistor in a short circuit, thereby preventing causing danger.
Description
Technical field
The utility model belongs to kitchen small household appliances technical field, is specifically related to a kind of temperature-sensing cup that container is protected with regard to the no pot that does not heat that do not have.
Background technology
Present commercially available low pressure electric cooker and micro computer electric cooker and pressure cooker, great majority are not have a pot protective device, even when interior pot is not placed on the heating plate, also can open heater switch, make the heat-generating disc heating.So just easily utensil is burnt, influence the service life of electric cooker.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art; the utility model provides a kind of temperature-sensing cup that does not have the pot protection; utilize the gravity of pot in the perception to make movable contact spring and static contact interoperation, thereby disconnect and the connection thermistor, temperature signal is sent to chip realize whether heating.
The technical scheme that its technical problem that solves the utility model adopts is:
This temperature-sensing cup that does not have the pot protection comprises housing, is stamped the cup cover on the housing, is provided with cup in the housing, and thermistor is contained on the cup, and the below of housing is provided with mount pad, is supported with outer spring between housing and the mount pad; Mount pad is provided with push rod, and stretch in the housing this push rod upper end, and its upper end is provided with movable contact spring; Be provided with the static contact that is complementary with this movable contact spring in the housing, this static contact is connected with thermistor.Like this, temperature-sensing cup is in normally closed dress attitude all the time when not putting container after powering on, and movable contact spring and the static contact short circuit thermistor that joins prevents danger.
Further, movable contact spring is tapered, is sleeved on the push rod upper end; Described static contact is positioned at the movable contact spring outside, is and the corresponding taper of movable contact spring.It is that 360 degree lines contact that movable contact spring adopts conical design with static contact, and movable contact spring touches mutually along the tapering of static contact when action, thereby reduces loose contact.Movable contact spring is designed to split ring, and the property material of employing is convenient for assembly.
Further, be provided with inner spring between push rod upper end and the cup.Like this, cooperatively interact, not only be convenient to resetting of cup assembly, be more convenient for going up the location of cup assembly with outer spring.
The utility model beneficial effect: the utility model utilizes the gravity of pot in the perception to make movable contact spring and static contact interoperation, thereby disconnects and the connection thermistor, temperature signal is sent to chip realize whether heating.Pot is in normally closed dress attitude during container all the time in not putting, and movable contact spring and the static contact short circuit thermistor that joins prevents danger.

Description of reference numerals: bowl cover 1, housing 2, thermistor 3, movable contact spring 4, static contact 5, push rod 6, cup 7, inner spring 8, outer spring 9, mount pad 10.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to accompanying drawing: the temperature detector of this no pot protection, comprise housing 2, the riveted joint of going up of housing 2 has cup cover 1.Be provided with cup 7 in the housing 2, thermistor 3 is contained on the cup 7.Thermistor 3 lower ends downward are passed mount pad 10, are connected with heater circuit.The below of housing 2 is provided with mount pad 10, is supported with outer spring 9 between housing 2 and the mount pad 10; Mount pad 10 is provided with push rod 6, and stretch in the housing 2 these push rod 6 upper ends, and its upper end is provided with movable contact spring 4.Be provided with the static contact 5 that is complementary with this movable contact spring 4 in the housing 2, this static contact 5 is connected with thermistor 3.Movable contact spring 4 is tapered, is sleeved on push rod 6 upper ends.Static contact 5 is positioned at movable contact spring 4 outsides, is and movable contact spring 4 corresponding tapers.It is that 360 degree lines contact that movable contact spring adopts conical design with static contact, and movable contact spring touches mutually along the tapering of static contact when action, thereby reduces loose contact.Movable contact spring is designed to split ring, and the property material of employing is convenient for assembly.Be provided with inner spring 8 between push rod 6 upper ends and the cup 7.
The utility model course of work is as follows:
The utility model temperature-sensing cup is contained on the base of electric cooker and pressure cooker, is used for pot bottom temperature in the perception.After interior pot was put into electric cooker and pressure cooker, as shown in Figure 3, the gravity effect of pot moved down in the last cup of temperature-sensing cup was subjected to, thereby driving static contact 5 moves down, movable contact spring 4 disconnects with static contact 5, and thermistor 3 sends detected signal to control element, and can heat this moment.After interior pot broke away from temperature-sensing cup, as shown in Figure 2, last cup was because the effect of outer spring 9 moves up, and the movable contact spring 4 formation short circuit that contacts with static contact 5 is not at this moment for heating.
Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
