[0003] The problem to be solved by the utility model is to propose an improvement plan or a replacement plan for the shortcomings of the above-mentioned prior art, especially a plan that can quickly and accurately detect the NTC performance of the hot tank temperature of the water purifier.

[0004] In order to solve the above problems, the scheme adopted by the utility model is as follows: a heating temperature measuring mechanism for detecting the NTC performance of the hot tank temperature of a water purifier, characterized in that the heating temperature measuring mechanism includes a main body; the main body is a copper rod, a heating groove is provided in the center of the copper rod, and a heating rod is arranged in the heating groove for heating the main body; a water collecting tray matching the NTC temperature of the hot tank of the water purifier is provided on the top of the main body, a water replenishment hole is provided at the bottom of the water collecting tray, a water replenishment waterway is provided in the main body, the water replenishment waterway runs through the main body, and one end thereof is connected to the water replenishment hole, and the other end is located at the bottom of the main body and connected to the water storage tank; an overflow hole is provided on the upper part of the water collecting tray, and a water outlet waterway is provided in the main body, the water outlet waterway runs through the main body, and one end thereof is connected to the overflow hole, and the other end is located at the bottom of the main body and connected to the water storage tank; a temperature measuring resistor mounting hole is provided at the bottom of the main body, and a temperature measuring resistor is arranged therein for collecting and controlling the temperature of the copper rod; a second temperature measuring resistor mounting hole is provided on the upper part of the main body that runs through the water collecting tray, and a second temperature measuring resistor is arranged therein for detecting the temperature of water in the water collecting tray.

[0005] Furthermore, the heating temperature measuring mechanism for detecting the NTC performance of the hot tank temperature of the water purifier is characterized in that the gaps between the heating rod and the heating tank, and between the temperature measuring resistor and the mounting hole of the temperature measuring resistor are filled with thermal grease.

[0006] Furthermore, the heating temperature measuring mechanism for detecting the NTC performance of the hot tank temperature of the water purifier is characterized in that a base is provided at the bottom of the main body, and the base is a quick-insert structure.

[0007] Furthermore, the heating temperature measuring mechanism for detecting the NTC performance of the hot tank temperature of the water purifier is characterized in that the connection between the water supply channel and the water supply hole coincides with the second temperature measuring resistor installation hole, and the second temperature measuring resistor is inserted into the water supply channel.

[0008] Working principle: The hot tank of the water purifier is buckled on the heating and temperature measuring mechanism. At this time, the convex surface of the bottom of the hot tank (the hot tank NTC installation position) is inserted into the water collection tray on the top of the copper rod. During this period, the heat transfer of the water in the water collection tray heats the hot tank NTC collection part. The whole process will collect the second temperature measuring resistor of the water collection tray and the NTC of the hot tank in real time, and compare the data to detect whether the performance of the hot tank NTC is qualified.

[0009] Self-test of the heating and temperature measuring mechanism: water is continuously supplied to the water collecting tray and the heating rod is started for a period of time. During this period, the temperature measuring resistor and the second temperature measuring resistor are collected in real time, and the data are compared to complete the self-test.

[0010] The technical effects of the utility model are as follows: the heating and temperature measuring mechanism is composed of a copper rod body and a quick-insert base. The heating rod in the copper rod heats the copper rod, and the temperature of the copper rod is collected and regulated by a temperature measuring resistor. The water supply channel runs through the copper rod, and the water flowing through it is heated by the copper rod, and then collected in the water collecting tray, and finally returns to the water storage tank through the overflow hole and the water outlet channel. The hot tank of the water purifier is buckled on the heating and temperature measuring mechanism. At this time, the convex surface of the bottom of the hot tank (the hot tank NTC installation position) is inserted into the water collecting tray at the top of the copper rod. During this period, the hot tank NTC collection part is heated by the heat transfer of the water in the water collecting tray. The performance of the hot tank temperature NTC of the water purifier is detected by comparing the readings of the second temperature measuring resistor and the hot tank temperature NTC of the water purifier. The heating and temperature measuring mechanism of the present application has a placement detection function, which is very convenient. It can also be designed to carry out up and down feeding and discharging movements through a mechanism composed of a cylinder and a slide rail to complete automatic detection, which is suitable for factory-scale large-scale production.
