Detailed Description

The embodiments of the invention will be described in detail below with reference to the attached drawings, but the invention can be implemented in many different ways as defined and covered by the claims:

as shown in fig. 1-6, the utility model provides an inside combination formula electric heater for firing oil cleaner, including canister 3, filter seat 5, lower casing 1, filter seat 5 connects in canister 3's upper end, and casing 1 connects in canister 3's below down, all is equipped with heating member assembly 2 in filter seat 5, the lower casing 1, is equipped with filter oil inlet 51, filter oil-out, 52 on the filter seat 5.

The heating body assembly 2 comprises an outer heat conducting fin 22, a heating fin 26, an inner heat conducting fin 21, a fixing plate 25 and a fastening assembly, wherein the outer heat conducting fin 22, the heating fin 26, the inner heat conducting fin 21 and the fixing plate 25 are sequentially connected together from top to bottom through the fastening assembly, and the outer heat conducting fin 22, the inner heat conducting fin 21 and the fixing plate 25 are all of a circular ring-shaped structure.

The fixing plate 25 is provided with a fixing plate stud 251, and the outer heat conducting fin 22, the inner heat conducting fin 21 and the heating fin 26 are all provided with through holes 221; the fastening assembly comprises a pressing sheet 27 and a tapping screw 28, the tapping screw 28 penetrates through the three through holes 221 and then is connected with the fixing plate stud 251, the pressing sheet 27 is sleeved on the tapping screw 28 and is in contact with the upper surface of the outer heat conducting sheet 22, and the outer heat conducting sheet 22, the heating sheet 26, the inner heat conducting sheet 21 and the fixing plate 25 can be fixed together through the matching of the tapping screw 28 and the fixing plate stud 251. Therefore, when the heating body assembly 2 is installed in the lower case 1, a method of fixing the fixing plate 25 of the heating body assembly 2 to the lower case 1 may be employed, and similarly, the method of installing the heating body assembly 2 in the filter base 5 may be the same.

The bottom of the fixing plate 25 is provided with a temperature control switch 23, the heating sheet 26 is electrically connected with the temperature control switch 23, the heating sheet 26 can transfer heat to the inner heat conducting sheet 21 and the outer heat conducting sheet 22 after being electrified, and the temperature control switch 23 can control the heating sheet 26 to stop being electrified and heated after being electrified and heated to a certain temperature. The heater chip 26 is made of PTC material.
