Detailed Description

The following describes the heating element assembly and the electric heating drinking water device using the same in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 5, the heating element assembly of the present embodiment is mainly composed of a sleeve 1, a heating rod 2 installed in the sleeve 1, a silica gel water outlet pipe joint 3 hermetically sleeved at the upper end of the sleeve 1, an upper cover 4, a silica gel water inlet pipe joint 5 hermetically sleeved at the lower end of the sleeve 1, a lower cover 6, and a positioning silica gel 7. Have the outlet conduit 30 of intercommunication silica gel outlet pipe joint 3 and the rivers passageway 8 of the inlet conduit 50 of silica gel inlet pipe joint 5 between sleeve 1 and the

heating rod

2, 2 bottom peripheries at the heating rod are equipped with spacing bulge loop 20, set up the opening 22 of intercommunication inlet conduit 50 on heating rod 2 and the spacing bulge loop 20, the bottom face have with external connection, power supply terminal 21 for heating rod 2 provides the power, silica gel inlet pipe joint 5 bottom is equipped with the through-hole 51 that power supply terminal 21 wore out. The positioning silica gel 7 is located between the sleeve 1 and the heating rod 2 to position the heating rod 2, and in addition, in order to make the water flow smooth and reduce the resistance, it is preferable to provide a water flow port 70 on the positioning silica gel 7, which is matched with the opening 22 of the heating rod 2 and is communicated with the water inlet pipe 50. In order to make the silicone tube connect comparatively reliably fixed connection, fix the extrusion of upper cover 4 on the lateral wall of silica gel outlet pipe joint 3, lower cover 6 extrusion is fixed on the lateral wall of silica gel water inlet pipe joint 5, and after fixing, heating rod 2 can make heating rod 2 placed in the middle under the effect of spacing bulge loop 20 in bottom and location silica gel 7, makes 8 circumferential clearances of rivers passageway even to promote heating efficiency.

In order to improve the operability and sealing performance during fastening assembly, sealing rings are preferably arranged on the inner side wall and the outer side wall of the silica gel water outlet pipe joint 3, the silica gel water inlet pipe joint 5 and the positioning silica gel 7, and the sealing rings are generally of an integrally formed structure, so that the reduction of the assembly resistance is realized through the deformation effect of the sealing rings during extrusion fit, and meanwhile, the sealing effect can be realized, such as the sealing ring 71 of the positioning silica gel 7.

Because the rivers of silica gel water inlet pipe head 5 department, the water of receiving the water pump delivery usually, pressure is great, only flows in one side of heating rod 2 for avoiding rivers to follow the front end of heating rod 2 to the rear end fast, just sets up water flow resistance flange 23 to opening 22 position in the top of location silica gel 7 to make rivers form a buffering effect, make water can carry out even heat exchange with the peripheral surface of heating rod 2 fully, promote the heating effect. In order to control the temperature of the outlet water, the outlet pipe 30 of the silica gel outlet pipe joint 3 is preferably designed to be a three-way pipe structure, and the middle pipe can be provided with a temperature sensing probe 9.

The heating element assembly is generally used for an electric heating water drinking device.
