Abstract
The utility model discloses a temperature limiter of multiple protection functions. The temperature limiter comprises a power assembly, a switching assembly, an adjusting mechanism and a resetting device. The power assembly comprises a diaphragm capsule assembly, a metal capillary tube and a temperature sensing pack, and the temperature sensing pack is connected with the metal capillary tube. The adjusting mechanism comprises an adjusting screw arranged above the power assembly. The utility model is characterized in that the switching assembly comprises a movable contact spring, a bow-spring, a static contact and a movable contact, the movable contact is arranged at the end part of the movable contact spring, and the bow-spring is arranged on the movable contact spring; an elastic instant activating switch is formed by the movable contact spring, the bow-spring, the static contact and the movable contact; the movable contact spring is a sheet body, a spring of which one end is provided with an opening is arranged on the sheet body, and the spring forms an angle with the sheet body; the bow-spring is an annular sheet body of which one end is provided with an opening, and one end of the bow-spring is a long and straight sheet body. The utility model has the advantages of multiple protection functions.
Description
Technical field
The utility model relates to a kind of temperature limiter, specifically a kind of temperature limiter with multiple protection functions.
Background technology
On the product of the existing high temperature heater (HTH) that comprises electric heater, electric rice cooker etc. heating control apparatus is installed all; this heater is generally controlled by thermostat; when thermostat break down malfunctioning after; temperature is very easily out of hand, even causes accidents such as fire, therefore; how the temperature controller of high temperature outage multiple protective can be provided; when temperature rises to predetermined protection value, can cut off heater circuit, become a difficult problem of pendulum in face of people.
Summary of the invention
The purpose of this utility model provides a kind of temperature limiter with multiple protection functions.
The purpose of this utility model is achieved through the following technical solutions.
A kind of multiple protection functions temperature limiter; comprise Power Component, switch module, adjusting mechanism and resetting means; Power Component comprises capsule stack, metal capillary and bulb; bulb is connected with metal capillary; adjusting mechanism comprises the adjustment screw that is positioned at the Power Component top; it is characterized in that: described switch module comprises movable contact spring, bow spring, fixed contact and moving contact; moving contact is positioned at the end of movable contact spring; the bow spring is installed on the movable contact spring, and movable contact spring, bow spring, fixed contact and moving contact are formed an elasticity moving switch of moment.
Described movable contact spring is plates, plates be provided with an end opening and with plates shell fragment at angle.
The annular slice body that described bow spring is a side opening, an end of bow spring is long straight lamellar body.
After disconnecting, described limit temperature must make snap switch can recover to limit automatically temperature state with artificial promotion release link; Power Component produces phenomenons such as leakage or capillary fracture, the also necessary automatic disconnection of snap switch; Above function relies on the physical dimension of kinetic energy sheet and spring to realize.
The utility model compared with prior art has the following advantages.
Multiple protection functions temperature limiter described in the utility model has the following advantages: when the temperature of utensil and protected device was raised to the temperature of (or reaching) restriction, temperature limiter cut off the circuit of heater automatically, stops heating.Heating appliances is protected; Behind automatic cut-out heating circuit, must manually fix a breakdown, human intervention is used the hand propelled release link then, can make temperature limiter recover limit temperature state automatically; The heart component of temperature limiter promptly produces the parts of pull switch power, in case (refrigerant leakage of the inside) bellows that breaks down shrinks, temperature limiter also can cut off switch automatically, and utensil is protected.
Description of drawings
Fig. 1 is the structural representation of the utility model multiple protection functions temperature limiter;
Fig. 2 is the structural representation of the utility model multiple protection functions temperature limiter bow spring;
Fig. 3 is the structural representation of the utility model multiple protection functions temperature limiter movable contact spring.
Embodiment
Below in conjunction with accompanying drawing the utility model multiple protection functions temperature limiter is described in further detail.
As Fig. 1, Fig. 2 and shown in Figure 3, multiple protection functions temperature limiter described in the utility model mainly is made up of Power Component, switch module, adjusting mechanism and resetting means.Power Component is welded into a sealed volume by capsule stack 1, metal capillary 2 and bulb 3, the sealed volume the inside has charged a kind of temperature sensing medium, after bulb is experienced temperature, the temperature sensing medium of the inside expands or shrinks, thereby make the rubber-like bellows produce displacement, produce the power of pull switch action.Switch module mainly is made up of with moving contact 7 movable contact spring 4, bow spring 5, fixed contact 6, and moving contact is positioned at the end of movable contact spring, and the bow spring is installed on the movable contact spring, and movable contact spring, bow spring, fixed contact and moving contact are formed an elasticity moving switch of moment.Movable contact spring is plates, plates be provided with an end opening and with plates shell fragment at angle.The bow spring is the annular slice body of a side opening, and an end of bow spring is long straight lamellar body.When variations in temperature, bellows produces displacement and promotes push rod, and push rod makes movable contact spring distortion and compression bend spring, and after distortion surpassed the upset plane, snap switch overturn rapidly, contact was disconnected or connection, reached the purpose of control circuit.Be positioned at the adjustment screw of Power Component top or the temperature that adjusting screw(rod) 8 can be used for adjusting qualification in the adjusting mechanism.After cutting off, the temperature limiter switch must press release link, the switch recovery operate as normal that could normally reset.
