Further, described gland is provided with the through hole for conduit movement.

This utility model electronic thermostat carries out to paraffin actively heating by heating assembly, thus allowing paraffin to expand, pushes away Dynamic ejector pin moves, and further promotion conduit moves, thus driving water shutoff packing ring to move, thus opening thermostat, realizes actively Adjustment, is conducive to preferably controlling cooling water temperature.

Brief description

Fig. 1 is the structural representation of the better embodiment of this utility model electronic thermostat.

Fig. 2 is the structural representation of shell.

Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in figure 1, the structure of the better embodiment of this utility model electronic thermostat includes shell 1, gland 3, leads Pipe 2, positioning disk 61, temperature-sensitive shell 62, ejector pin 5, expansion tube 51, heating assembly 8, water shutoff packing ring 4, spring 9 and collet 63.Institute State gland 3 and be fixed on shell 1 upper end, the lower end of described shell 1 is provided with exhalant canal 111, described conduit 2 is located at gland 3 and goes out Between aquaporin 111, described water shutoff packing ring 4 is located on conduit 2 with the exhalant canal 111 in sealing shell 1.9 sets of described spring It is located on conduit 2, and the two ends of spring 9 are abutted with water shutoff packing ring 4 and gland 3.Described positioning disk 61, temperature-sensitive shell 62 and collet 63 all in conduit 2, and the two ends of described temperature-sensitive shell 62 are connected with positioning disk 61 and collet 63.It is provided with described temperature-sensitive shell 62 Paraffin 7 and expansion tube 51, described paraffin 7 is located between expansion tube 51 and heating assembly 8, and described heating assembly 8 is located at collet In 63.Described expansion tube 51 can be provided with accommodating chamber by external force crimp in described expansion tube 51, and described ejector pin 5 lower end is located at Accommodate intracavity, the upper end of described ejector pin 5 is located on sleeve pipe.Described collet 63 is used for protection heating assembly 8 and heating group Wire 81 on part 8.Described heating assembly 8 is heating chip.

Described shell 1 includes body 11 and the support 12 being located at body 11 two ends and thread-protected tube 13.On described support 12 It is provided with draw-in groove, described gland 3 is fastened in draw-in groove.Described thread-protected tube 13 is integrally formed with described body 11, is easy to technique manufacture. Described body 11 is provided with exhalant canal 111, and described thread-protected tube 13 is in exhalant canal 111, and will not seal exhalant canal 111, cooling water flows out from the both sides of thread-protected tube 13.It is provided with string holes, the wire 81 on heating assembly 8 is from this string holes in thread-protected tube 13 Pass and be connected with the control section of vehicle.

Described gland 3 is provided with the through hole for conduit 2 movement, and conduit 2 is located at below gland 3, can save space.

When cooling water needs to carry out systemic circulation, heating assembly 8 is made paraffin 7 to be carried out actively heat, thus making paraffin 7 swollen Swollen, paraffin 7 expands extrusion expansion pipe 51, and expansion tube 51 extrudes ejector pin 5, thus promoting ejector pin 5 to move up, shipper pole on ejector pin 5 Dynamic sleeve pipe moves up, and sleeve pipe drives water shutoff packing ring 4 to overcome the pressure of spring 9 to move, so that water shutoff packing ring 4 opens shell 1 Exhalant canal 111, that is, open thermostat, realize active accommodation, be conducive to preferably controlling cooling water temperature.

These are only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every profit The equivalent structure made with this utility model description and accompanying drawing content, is directly or indirectly used in other related technology necks Domain, all in the same manner within scope of patent protection of the present utility model.
