Abstract
The utility model provides a protection device of an electro-thermal constant temperature heating sleeve. The protection device comprises an electro-thermal wire glass fiber cotton layer, wherein a surface of the electro-thermal wire glass fiber cotton layer is covered with aluminum foil paper, and a liquid leakage sensor is arranged between the electro-thermal wire glass fiber cotton layer and the aluminum foil paper. According to the protection device, the surface of the electro-thermal wire glass fiber cotton layer is covered with the aluminum foil paper; the liquid leakage sensor and a power failure protection device are mounted; corrosion and short circuit caused by liquid leakage are prevented; and service life of the electro-thermal constant temperature heating sleeve is prolonged.
Description
Technical field
The utility model relates to the chemical analysis instrument technical field, particularly a kind of protective device of electric heating constant temperature heating collar.
Background technology
Be that glass fibre cotton by insulation high-temperature-resistant wraps on the heating wire of existing electric heating constant temperature heating collar, can play well the effect that insulation is conducted heat.But can not prevent the infiltration of liquid, when cause solvent outflow or condensed water to flow into heating tank because of the operation reason due to solvent bumping or other reason, infiltrate the contact heating wire by cellucotton, easily cause its corrosion, damage shortens its useful life.
The utility model content
The utility model provides a kind of protective device of electric heating constant temperature heating collar, in case major structure becomes corrosion or damages.
To achieve these goals, the utility model provides following technical scheme:
A kind of protective device of electric heating constant temperature heating collar comprises heating wire glass fibre cotton layer, and wherein, the surface coverage of described heating wire glass fibre cotton layer has aluminium-foil paper, is provided with leakage sensor between described heating wire glass fibre cotton layer and described aluminium-foil paper.
Preferably, described leakage sensor is connected with power-off protection apparatus.
By implementing above technical scheme; has following technique effect: the protective device of the electric heating constant temperature heating collar that the utility model provides; surface coverage aluminium-foil paper at the heating wire glass fibre cotton; leakage sensor and power-off protection apparatus are installed; prevent from causing corrosion and short circuit, the useful life of improving the electric heating constant temperature heating collar because liquid infiltrates.
Description of drawings
The structural representation of the protective device of the electric heating constant temperature heating collar that Fig. 1 provides for the utility model embodiment.
Embodiment
In order better to understand the technical solution of the utility model, describe below in conjunction with accompanying drawing the embodiment that the utility model provides in detail.
The utility model embodiment provides a kind of protective device of electric heating constant temperature heating collar; as shown in Figure 1; comprise heating wire glass fibre cotton layer 106; the surface coverage of described heating wire glass fibre cotton layer 106 has aluminium-foil paper 105, is provided with leakage sensor 101 between described heating wire glass fibre cotton layer 106 and described aluminium-foil paper 105.Aluminium-foil paper 105 can be high temperature resistant and the glass fibre cotton in solution and heating wire glass fibre cotton layer 106 and heating wire can be intercepted and come, if cause the solution seepage to be gone down because aluminium-foil paper 105 breaks, leakage sensor 101 has detected the solution seepage, process so that do further, as passing through sound or light warning.
In other embodiments, on above-described embodiment basis, further, described leakage sensor 101 is connected with power-off protection apparatus, if leakage sensor has detected leakage, can start power-off protection apparatus, with better over cap electric heating constant temperature heating collar.
In the various embodiments described above, the protective device of this electric heating constant temperature heating collar also comprises mains switch 103 and power failure lamp 104, with (as the control by power-off protection apparatus) or manually outage automatically.In addition, the protective device of this electric heating constant temperature heating collar also comprises temperature control button 102, to control the temperature of this electric heating constant temperature heating collar.
The protective device of above a kind of electric heating constant temperature heating collar that the utility model embodiment is provided is described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; all will change in specific embodiments and applications; in sum, this description should not be construed as restriction of the present utility model.
Claims (2)
