Abstract
The utility model discloses an electric tubular heater for a hot-water bag. The electric tubular heater comprises an insulated mounting seat (1) and a heating tube having two ends connected with the mounting seat. The heating tube includes an outer insulated thermal conductor (2) and an inner conductive heater. The conductive heater is connected with conductive screws (3) at two ends of the heating tube. The mounting seat is provided with through holes (5) for the two conductive screws to pass through. One end of the through hole has an inlet for the conductive screw to go in, while the other end has an outlet for the conductive screw to go out. The conductive crews are inserted into the through holes. Nuts in threaded connection with the conductive screws are arranged at the outlet-side. The top of the insulated thermal conductor pushes up against the mounting seat at peripheral positions of the inlet, and the nuts push up against the mounting seat at peripheral positions of the outlet. Compared with the prior art, the electric tubular heater provided by the utility model has the advantages of good sealing performance, leakage resistance, safety and practicality.
Description
Technical field
The utility model relates to hot-water bottle field, relates in particular to a kind of hot-water bottle electric tube heater.
Background technology
The defect of existing hot-water bottle electric tube heater is: the connection of mount pad and heating tube is difficult to realize seamless sealing, cause the water capacity in hot-water bottle easily from the combination weakness generation seepage of mount pad and heating tube, once and seepage occurs to cause short circuit, not only can damage product, impact use, also leave potential safety hazard simultaneously.
Utility model content
In view of this, technical problem to be solved in the utility model is: provide a kind of good seal, antiseep, safe and practical hot-water bottle electric tube heater.
In order to achieve the above object, the utility model adopts following technical scheme to realize:
A kind of hot-water bottle electric tube heater, comprise the heating tube that the mount pad of insulation is connected with described mount pad with two ends, the outside of described heating tube is insulating thermal conductor, inside is conductive heater body, wherein, described conductive heater body is connected with conduction screw in the two ends of described heating tube, described mount pad is provided with for two perforation that described conduction screw wears respectively, the entrance of one end of described perforation for penetrating for described conduction screw, the outlet of the other end for passing for described conduction screw, described conduction screw is located in described perforation, also be included in described outlet side and be screwed onto the nut on described conduction screw, the top, end of described insulating thermal conductor presses described mount pad on the peripheral position of described entrance, described nut top presses described mount pad on the peripheral position of described outlet.
As preferably, described mount pad is provided with to hold the cavity of nut in the end face of described outlet side.
As shown from the above technical solution, the beneficial effects of the utility model are:
Compared to existing technology, the utility model good seal, antiseep, safe and practical.Particularly, nut, in screwing tight the process of conduction screw, can drive heating tube to carry on the whole, and the end of insulating thermal conductor can be pushed up on the perforation entrance peripheral position that is pressed in mount pad more and more closely, thereby can realize the sealing completely of the two connection, stop seepage.Aspect the attaching with hot-water bottle, only mount pad need be sealedly connected on the inwall of hot-water bottle reserved opening periphery, simple and convenient.
