Heating pipe positioning structure of pipeline heater for instant drinking water heating device

Abstract

The invention relates to a heating pipe positioning structure of a pipeline heater for an instant drinking water heating device. The heating pipe positioning structure of the pipeline heater for the instant drinking water heating device comprises the pipeline heater which comprises a water guide pipe and a heating pipe. The water guide pipe comprises a water inlet, a pipe cavity and a water outlet. The heating pipe is arranged in the pipe cavity of the water guide pipe. The heating pipe is used for heating water flowing through the pipe cavity of the water guide pipe, and the heating pipe is provided with a conductive end. The conductive end of the heating pipe extends out of the water guide pipe. A positioning block is arranged in the pipe cavity of the water guide pipe and used for clamping the heating pipe so that the heating pipe in the water guide pipe can be clamped and positioned in the water guide pipe by the positioning block. According to the heating pipe positioning structure, by simply arranging the positioning block at one end of the heating pipe into the water guide pipe, the end, in the pipe cavity, of the heating pipe is clamped and positioned in the water guide pipe by the positioning block, and the defects that the heating pipe swings in the pipe cavity and even impacts the pipe wall are overcome. In addition, the heating pipe positioning structure is simple and reasonable in structure and easy to implement, the end, in the pipe cavity, of the heating pipe is well protected, and the defects of deformation, damage, electric leakage and the like caused when the heating pipe impacts the pipe wall are overcome.

Description

technical field [0001] The invention relates to an instant drinking water heating device, in particular to a pipe heater heating pipe positioning structure for the instant drinking water heating device. Background technique [0002] Existing instant heating devices for drinking water, such as: instant electric water boilers, tea making appliances and water dispensers with electric heating, etc., most of the heaters used are instant pipeline heaters; traditional pipeline heaters , its structure generally includes a water guide tube and a heating tube. The water guide tube includes a water inlet, a lumen and a water outlet. The heating tube is inserted from one end of the water guide tube and extends into the lumen to the other end close to the lumen. The water in the lumen of the aqueduct is heated, and the heat pipe is inserted into one end of the aqueduct. In order to prevent water leakage, a fixing and sealing mechanism is generally provided, but the other end of the heat ...

[0002] Existing instant heating devices for drinking water, such as: instant electric water boilers, tea-making appliances and water dispensers with electric heating, etc., most of the heaters used are instant pipeline heaters; traditional pipeline heaters , its structure generally includes a water guide tube and a heating tube. The water guide tube includes a water inlet, a lumen and a water outlet. The heating tube is inserted from one end of the water guide tube and extends into the lumen to the other end close to the lumen. The water in the lumen of the aqueduct is heated, and the heat pipe is inserted into one end of the aqueduct. In order to prevent water leakage, etc., a fixing and sealing mechanism is generally provided, but the other end of the heat pipe is suspended in the lumen, that is: the other end of the heat pipe One end is not provided with any fixing mechanism; the above-mentioned traditional pipe heater has the following disadvantages: (1) Since one end of the heating pipe extending into the water pipe is suspended, this end of the heating pipe is easy to touch the water pipe The inner wall causes the wall of the aqueduct to overheat, so that the anti-dry temperature control device monitoring the wall of the aqueduct is easy to operate "power-off protection", which affects normal use; The heating tube causes the deformation of the heating tube, and even the anti-leakage coating on the outer wall of the heating tube is scratched, resulting in leakage
