Detailed ways

The specific implementation of the heating element assembly and the electric heating drinking water device adopting the heating element assembly of the present invention will be further described in detail below in conjunction with the accompanying drawings.

As shown in Figures 1 to 3, the heating element assembly of this embodiment mainly consists of a heating sleeve 1, a flow guide tube 2 installed in the heating sleeve 1, and a second upper end of the heating sleeve 1 and the flow guide tube 2. A pipe joint 3 is composed of a second pipe joint 4 located at the lower end of the heating sleeve 1 and the flow guide tube 2. There is a water flow channel 5 between the heating sleeve 1 and the flow guide tube 2, and the water flow channel 5 passes through the first pipe joint The first opening 31 on 3 and the second opening 41 on the second pipe joint 4 communicate with each other. In order to enhance the turbulence effect, a partition 91 is vertically arranged on the outer wall of the guide tube 2 and a labyrinth water tank 9 is arranged from bottom to top along the partition board 91, and the entrance of the labyrinth water tank 9 communicates with the first pipe joint 4 , the outlet of the labyrinth tank 9 communicates with the second pipe joint 3 . The heating sleeve 1 includes a heating coating 10 distributed on the outer wall of the heating sleeve 1 and electrodes 11 located at both ends of the heating coating 10. The heating coating 10 is usually made of heating materials such as graphite or rare earth. A sealing body 7 is usually provided between the heating sleeve 1 and the first pipe joint 3 and/or the first pipe joint 4, which can be made of silicone material. In order to facilitate assembly and fixation, a first mounting shell 80 and a second mounting shell 81 can be provided outside the heating sleeve 1, and the upper and lower ends of the first mounting shell 80 and the second mounting shell 81 are respectively provided with threaded connecting columns 82, and the second A pipe joint 3 is provided with a first connection hole 30 that cooperates with the threaded connection column 82, and the second pipe joint 4 is provided with a second connection hole 40 that cooperates with the threaded connection column 82, and the screw passes through the first connection hole 30 or The second connecting hole 40 is then fastened on the threaded connecting post 82 . In order to accurately control the outlet water temperature, a temperature control probe 86 can be sealed on the first pipe joint 3 or the second pipe joint 4, and of course the temperature control probe 86 can also be installed on the first pipe joint 3 and the second pipe joint 4 at the same time, usually An opening is provided at one end of the pipe joint, and a sealing ring 87 is sleeved on the front end of the temperature control probe 86, and then fixed by a clip 88 provided on the pipe joint.
