Abstract
The invention relates to a constant-temperature temperature controller which comprises an adjustable shaft arranged on a support, an insulating porcelain ring and bimetallic strips. A first lug plate is arranged on the insulating porcelain ring, and is connected with a leaf spring, a second lug plate is arranged on the insulating porcelain ring, and is connected with a contact chip, one end of an insulating porcelain rice is connected with one end of the leaf spring, the other end of the insulating porcelain rice is connected with a straight-shaped bimetallic strip, and the first lug plate is separated from the second lug plate through an insulating ring on the insulating porcelain. The constant-temperature temperature controller further comprises an annular bimetallic strip, and the other end of the insulating porcelain rice is connected with the straight-shaped bimetallic strip through the annular bimetallic strip. The annular bimetallic strip includes a base, a first extension side and a second extension side, wherein the first extension side and the second extension side are respectively connected with two ends of the base, and the other end of the insulating porcelain rice is connected with the first extension side. The constant-temperature temperature controller has the advantages that controlling temperature is near a constant temperature state, temperature control is sensitive, accuracy is high, and structure is simple and reasonable. In addition, the problems of large temperature control range, low accuracy of a traditional temperature controller are effectively solved.
Description
Technical field
The present invention relates to a kind of thermostat, particularly a kind of constant temperature thermostat.
Background technology
The tradition thermostat, shown in accompanying drawing 1-accompanying drawing 2, comprise the regulating shaft 1, insulation porcelain ring 6 and the bimetal leaf that are arranged on the support 10, the spring leaf 3 that is arranged on the first lug plate 2 on the insulation porcelain ring 6 and joins with the first lug plate 2, the contact chip 5 that is arranged on the second lug plate 4 on the insulation porcelain ring 6 and joins with the second lug plate 4, one end of insulation porcelain rice 7 and an end of spring leaf 3 join, the other end of insulation porcelain rice 7 joins with straight shape bimetal leaf 8, and the first lug plate 2 and the second lug plate 4 separate by the dead ring on the insulation porcelain ring 6.
Break-off signal and the temperature difference between the reset temperature of this traditional thermostat are large, generally between 10～20 ℃, this heater and ambient temperature that causes traditional thermostat to be controlled can only fluctuate in a larger temperature range, and can't satisfy some temperature difference amplitudes very little, near the control requirement of the ambient temperature of temperature constant state.
Summary of the invention
Purpose of the present invention aims to provide a kind of simple and reasonable, temperature control is sensitive, precision is high constant temperature thermostat, to overcome weak point of the prior art.
A kind of constant temperature thermostat by this purpose design, comprise the regulating shaft that is arranged on the support, insulation porcelain ring and bimetal leaf, the first lug plate is arranged on the insulation porcelain ring, the first lug plate and spring leaf join, the second lug plate is arranged on the insulation porcelain ring, the second lug plate and contact chip join, one end of insulation porcelain rice and an end of spring leaf join, the other end of insulation porcelain rice joins with straight shape bimetal leaf, the first lug plate and the second lug plate separate by the dead ring on the insulation porcelain ring, its architectural feature is also to comprise annular bimetal leaf, and the other end of insulation porcelain rice joins by annular bimetal leaf and straight shape bimetal leaf.
Described annular bimetal leaf comprises matrix and the first extension edge and the second extension edge that join respectively with the matrix two ends, and wherein, the other end of insulation porcelain rice and the first extension edge join, and straight shape bimetal leaf and the second extension edge join.
The cross section of the matrix of described annular bimetal leaf is the opening ring-type.
The cross section of described annular bimetal leaf in the form of a ring, a side of the other end of insulation porcelain rice and annular bimetal leaf is joined, the opposite side of straight shape bimetal leaf and annular bimetal leaf joins.
The cross section of described annular bimetal leaf is the opening ring-type.
The structure welding of the straight shape bimetal leaf among the present invention and annular bimetal leaf employing a positive and a negative together, its thermal deformation bending direction was inverse state after straight shape bimetal leaf and annular bimetal leaf joined, so it is large to have the rate of curving, the little characteristics of control temperature accuracy scope, can improve greatly the sensitivity of thermostat by annular bimetal leaf, having a narrow range of temperature between its break-off signal and the reset temperature, precision is high, general control is in 2 ℃, this makes heater that thermostat controls and ambient temperature all the time in a very little temperature range, it is very little to satisfy some temperature difference amplitudes, ambient temperature control requirement near temperature constant state is fit to be applied in thermostatic equipment very much, medical constant temperature cabinet, thermostatic chamber, the aspects such as central air-conditioning.
The present invention has the control temperature near temperature constant state, and temperature control is sensitive, the high and simple and reasonable characteristics of precision, has effectively solved traditional thermostat and has controlled the problem that the warm width of cloth is large, precision is low.
