Problems solved by technology

[0002] Since some medicines, vaccines or temperature-sensitive solutions need an external temperature control device to control the temperature of the solution during use, a thermostat is needed to place the solution in the thermostat to achieve temperature control. At the same time, because These liquids are corrosive or acidic or alkaline, making it impossible to feedback the temperature of the solution through the sensor contacting the solution, and due to cost constraints, it is impossible to use advanced technology to collect temperature without contact, so a thermostat is needed, according to the environment Temperature change, control the temperature of heating components, realize the open-loop control of the temperature of the solution, and realize the temperature control of the solution through heat balance

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] like Figure 1-6 Shown is the shell 1 of the thermostat of the present invention. The main body of the shell 1 is two orthogonal rectangular cavities. When the shell 1 is placed normally, the bottom of the cavity (hereinafter referred to as cavity 12) where the solution bottle 14 is placed There are four columns 13, and the columns 13 are used to support the solution bottle body 14, and there are gaps 25 at the tops of the front and rear columns in the four columns 13 (the column near another cavity here is the rear column 13-2, away from the other The column of the cavity is the front column 13-1), which is used to install the PTC heating sheet 20, and the left side of the cavity one 12 has an observation lens installation port 9, which is used to install the observation lens 16 and observe the liquid in the liquid bottle body 14. The remaining amount of the s...

Abstract

The invention relates to a thermostat. The surface temperature of a heating assembly is controlled by feedback of change of an environment temperature, and temperature open-loop control to the temperature of a solution in the thermostat is realized. According to a first implementation mode, heating plates of a PTC are mounted on four stand columns of a cavity, a heating core wire of the PTC penetrates in a second cavity through a third special-shaped hole, two wires of a heating core of the PTC are connected to two of four binding posts on one side of a switch, an observing lens and a rear cover plate are mounted, a solution bottle is placed in the thermostat, then a power supply is switched on, and then the thermostat begins to work. According to a second implementation mode, a heating tube is mounted in a third special-shaped hole, a temperature sensor is mounted in a second special-shaped hole, heat-conduction oil is poured at a position surrounding the stand columns of the first cavity, a photoelectricity transistor is mounted in the third special-shaped hole, the temperature of the heat-conduction coil is acquired by the temperature sensor, when the temperature of the heat-conduction oil is lower than a set value, an integrated circuit board starts the heating tube to heat the heat-conduction oil, and when the temperature of the heat-conduction oil reaches the set value, heating stops.

Description

technical field [0001] The invention belongs to an open-type thermostat for constant temperature heating of a solution, in particular to a thermostat for temperature open-loop control. Background technique [0002] Since some medicines, vaccines or temperature-sensitive solutions need an external temperature control device to control the temperature of the solution during use, a thermostat is needed to place the solution in the thermostat to achieve temperature control. At the same time, because These liquids are corrosive or acidic or alkaline, making it impossible to feedback the temperature of the solution through the sensor contacting the solution, and due to cost constraints, it is impossible to use advanced technology to collect temperature without contact, so a thermostat is needed, according to the environment Temperature change, control the temperature of heating components, realize the open-loop control of the temperature of the solution, and realize the temperatur...
