Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The liquid heater chassis of the present embodiment, as shown in fig. 1 and 2, includes a kettle bottom cover 1, a first coupler 2 is disposed in the kettle bottom cover 1, as shown in fig. 4, a central hole 104 is formed in the middle of the kettle bottom cover 1, the first coupler 2 is a current general-purpose component, as shown in fig. 7, a support arm 202 is formed at the lower portion of the first coupler 2, the number of the support arms 202 is three, and the support arms 202 are uniformly distributed, a flange 201 is formed at the lower end portion of the first coupler 2, a cylindrical surface at the lowermost end of the first coupler 2 is in clearance fit connection with the central hole 104 of the kettle bottom cover 1, as shown in fig. 5, three mounting through holes 1021 are uniformly distributed in the kettle bottom cover 1, the mounting through holes 1021 correspond to through holes in the support arms 202, a tapping screw passes through the mounting through hole 1021 and is screwed to the through hole in the support arm 202 (note that the tapping, so that the flange 201 abuts the edge of the central hole 104 of the jug bottom cover 1, it can be seen that the flange 201 has a limiting effect on the jug bottom cover 1. The above description is prior art and is not detailed here.

As shown in fig. 4 and 6, at least three hooks 101 are formed on the inner bottom surface of the kettle bottom cover 1 of the present invention, the number of the hooks 101 shown in fig. 4 is three, as shown in fig. 1 and 8, the hooks 101 are fastened to the flange 201, as shown in fig. 6 and 8, two positioning posts 103 are formed on the inner bottom surface of the kettle bottom cover 1, and the supporting arm 202 is fittingly disposed between the two positioning posts 103. By arranging the clasp 101, when assembling, the two positioning columns 103 of the kettle bottom cover 1 are aligned with the supporting arms 202 and the cylindrical surface at the lowest end of the first coupler 2 is aligned with the central hole 104 by the mechanical arm, and the kettle bottom cover 1 is pressed and installed on the first coupler 2 by the mechanical arm, so that the clasp 101 is buckled on the flange 201, moreover, because the support arm 202 limits the angular positions of the two positioning posts 103, the through hole of the support arm 202 is aligned with the installation through hole 1021, after the process, because the support arm 202 limits the position of the two positioning posts 103, the bottom lid 1 cannot rotate relative to the first coupler 2, and since the hook 101 catches the flange 201, the kettle bottom cover 1 is difficult to be separated from the first coupler 2, thereby avoiding the displacement of the kettle bottom cover 1 and the first coupler 2 when moving between the assembling stations, it is advantageous to ensure that the self-tapping screws fit into the through-holes in the alignment support arms 202 during the next step of self-tapping screw installation. It can be seen that the utility model discloses a kettle bottom 1 of liquid heater chassis's structure is favorable to adapting to automatic assembly to be favorable to improving assembly efficiency.

Further, as shown in fig. 4, the hooks 101 are uniformly distributed in the circumferential direction, so that the hooks 101 are balanced in stress and not prone to roll when being assembled with the flange 201, and the assembly process is facilitated to be performed smoothly. Of course, it is also possible that the hooks 101 are not circumferentially uniformly distributed, but the circumferentially uniformly distributed arrangement of the hooks 101 is the optimal solution.

Further, as shown in fig. 6, a guiding slope 1011 for guiding during assembly is formed at the upper end of the hook 101, when the kettle bottom cover 1 is assembled to the first coupler 2, the guiding slope 1011 of the hook 101 contacts the flange 201 first, and the guiding slope 1011 facilitates the flange 201 to force the hook 101 to elastically deform and bend outwards, so that the flange 201 smoothly enters the hook 101, thereby making the assembly process smooth.

Further, as shown in fig. 6, the diameter of the positioning columns 103 is gradually reduced from bottom to top, when two positioning columns 103 are assembled to the supporting arm 202, the diameter of the upper ends of the positioning columns 103 is smaller, so the distance between the upper ends of the two positioning columns 103 is relatively larger, and errors are inevitably generated in assembly positioning, so that the positioning columns 103 are arranged, the two positioning columns 103 are favorably guided to be inserted into the two sides of the supporting plate 202, and the situation that assembly clamping stagnation is caused by assembly positioning errors can be avoided.

Further, as shown in fig. 4, the inner bottom surface of the kettle bottom cover 1 is formed with an installation boss 102 for supporting the support arm 202, the lower end surface of the support arm 202 abuts against the installation boss 102, a peripheral portion 1022 adapted to the end portion of the support arm 202 is formed at the edge of the installation boss 102, as shown in fig. 9, the end portion of the support arm 202 is semicircular, the peripheral portion 1022 is also semicircular, the peripheral portion 1022 surrounds the end portion of the support arm 202, the peripheral portion 1022 has a limiting effect on the support arm 202, when the kettle bottom cover 1 is assembled to the first coupler 2, the installation through hole 1021 of the kettle bottom cover 1 is further facilitated to be aligned with the through hole on the support arm 202, thereby facilitating the assembly process to be smooth, and facilitating the improvement of the assembly efficiency.

The above structure of the utility model is suitable for the liquid heater chassis which adopts the coupler connection mode, such as the tea boiling device, the health preserving kettle, the electric kettle, the coffee extractor and the milk adjusting device.

The utility model discloses a liquid heater, as shown in fig. 10, including liquid heater body 3 and liquid heater base 4, liquid heater body 3 is used for holding water or other food that need be cooked, the bottom of liquid heater body 3 is equipped with the heating wire, liquid heater base 4 is equipped with the second coupler, the second coupler is connected with the interior circuit board electricity of liquid heater base 4, still include foretell liquid heater chassis, first coupler 2 and liquid heater body 3's outer bottom fixed connection, the heating wire is connected with first coupler 2 electricity, first coupler 2 can be connected or separate with the second coupler.
