Description
Technical field
The present invention relates to environmental protection equipment accessory technical fields, more particularly, to a kind of high-precisive temperature controllers of environmental protection equipment.
Background technology
Currently, with the continuous improvement of people's environmental consciousness, environmental protection equipment has obtained a large amount of uses, and must in environmental protection equipment
It is wherein particularly important one kind so to use controller, temperature controller.Requirement of the people to the temperature controller used in environmental protection equipment
It is：Structure is relatively simple, cost is relatively low, accuracy is higher.
Invention content
The object of the present invention is to provide a kind of high-precisive temperature controllers of environmental protection equipment, it has precision higher, and structure compared with
For simple feature.
The technical solution adopted in the present invention is：The high-precisive temperature controllers of environmental protection equipment, including a fixed plate and first
Electrode, second electrode, the fixed plate are equipped with the glass infuser that is extended in the up-down direction, the inside of the glass infuser from up to
At least three outer hard contacts are had, the intracavity sidewall of the glass infuser is equipped with internal thread, and being equipped with one in the glass infuser lives
Plug, the external screw thread which is equipped with and internal thread matches, and the circumference side of the piston is equipped with metal in one
Contact, meanwhile, outer hard contact is distributed in the bottom of thread of the internal thread, and the height of adjacent outer hard contact is different and does not locate
In in the same vertical lines, and, interior hard contact and outer hard contact match, and the lower section of the nut is located in the glass infuser
Filled with mercury, the interior hard contact of first electrode electrical connection, second electrode and hard contact corresponding electrical connection two-by-two, the work
Compression spring is equipped between the upper surface of plug and the upper surface of the glass infuser.
The invention has the advantages that compared with the prior art,：Precision is higher, and structure is relatively simple.The ring of the present invention
Moving up and down for common piston when in use, to be formed the mode of variable, change into piston by the high-precisive temperature controllers for protecting equipment
The variable of rotation and formation, to make its precision obtain significant increase.Meanwhile the component of use is less, structure is relatively simple.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples：
Fig. 1 is the main view schematic cross-sectional view of the embodiment of the present invention.
In figure：
10, fixed plate；
20, glass infuser, 21, outer hard contact, 22, internal thread；
30, piston, 31, external screw thread, 32, interior hard contact；
40, mercury；
51, first electrode, 52, second electrode；
60, compression spring.
Specific implementation mode
Embodiment, as shown in Figure 1：The high-precisive temperature controllers of environmental protection equipment, including a fixed plate 10 and first electrode 51,
Second electrode 52.First electrode 51 is 1, and second electrode 52 is several.The fixed plate 10 is equipped with enterprising in above-below direction
The inside of the glass infuser 20 that row extends, the glass infuser 20 is equipped at least three outer hard contacts 21 from top to bottom.
Further say：
The intracavity sidewall of the glass infuser 20 is equipped with internal thread 22.A piston 30 is equipped in the glass infuser 20.30 circumference of piston
The external screw thread 31 that side is equipped with and internal thread 22 matches, and the circumference side of the piston 30 is equipped with hard contact 32 in one.
That is, when the piston 30 moves up and down, which will produce rotation simultaneously.Meanwhile outer hard contact 21 is distributed in the interior spiral shell
The height of the bottom of thread of line 22, adjacent outer hard contact 21 is different and is not in the same vertical lines.That is, all
The line of outer hard contact 21 is moved towards just along the screw thread of the internal thread 22.And interior hard contact 32 and outer hard contact
21 match.That is, when the piston 30 is rotating and rises or falls, which can contact some outer metal and touch successively
Point 21.In the glass infuser 20 mercury 40 is filled with positioned at the lower section of the nut 32.The first electrode 51 is electrically connected interior hard contact
32, second electrode 52 and the corresponding electrical connection two-by-two of hard contact 21.The upper end of the upper surface of the piston 30 and the glass infuser 20
Compression spring 60 is equipped between face.
The operation principle of the present invention：With the variation of ambient temperature, which can rise or fall, and it is inevitable with
Rotation makes interior hard contact 32 and one of those outer hard contact 21 contact and realize electrical connection, to 51 meeting of first electrode
It is formed and is electrically connected with one of second electrode 52, form a controller.Due to the raising and lowering compared to piston 30
It is affected by temperature and formed mobile range for, the mobile range of the interior hard contact 32 on postrotational piston 30 is wanted
It is much bigger, to the significant increase precision of controller.
It should be noted that the thickness of piston 30 should be sufficiently large, outer hard contact 21 can be touched to avoid mercury 40.
The foregoing is merely the preferred embodiment of the present invention, are not intended to limit the scope of the invention, every utilization
Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content is applied directly or indirectly in other correlations
Technical field, be included within the scope of the present invention.
