Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of liquid level sensor with heating function,
Including box cover 1, the bottom end of the box cover 1 is equipped with transmitter box 2, and the right end of the transmitter box 2 is equipped with connection jaws 3, institute
The bottom end for stating transmitter box 2 is equipped with conduit 5, and the outer wall of the conduit 5 is sequentially installed with mounting flange 4, the upper limit from top to bottom
Position plate 6, floating ball 7, lower limiting board 8, the lower end of the conduit 5 is equipped with ptc heater device 9, the ptc heater device 9
It is communicated with conduit 5, the ptc heater device 9 includes ptc heater crust of the device 91, the ptc heater crust of the device 91
Outer wall be equipped with electromagnetic shielding set 94, the inner cavity upper and lower part of the ptc heater crust of the device 91 is equipped with two arrays of electrodes plate
95, the top of the electrode plate 95 is connected with conducting wire 93, and the conducting wire 93 runs through ptc heater crust of the device 91, the conducting wire
