A laboratory drying oven based on the multiple reflection periscope temperature value of the mirror surface

Abstract

The invention discloses a mirror-surface multiple-reflection periscopic temperature value based drying oven for a laboratory. The mirror-surface multiple-reflection periscopic temperature value baseddrying oven is characterized by structurally comprising a drying oven main body, a storage net rack, a drying oven door, a visible window, a control panel, a temperature value periscopic device and acalibration temperature gauge, wherein the drying oven main body is of a rectangular structure; the storage net rack is arranged inside the drying oven main body. A periscopic mechanism is arranged, so that a temperature value hidden inside the drying oven can be reflected out through multiple mirror-surface reflection, an experiment personnel directly reads the temperature value conveniently, thetemperature gauge does not need to be pulled out or completely extend into the drying oven, an actual temperature in the drying oven is guaranteed to be accurately measured, calibration for the drying oven is convenient, and daily management needs are met; and a high-temperature ejecting-out mechanism is arranged, so that the temperature gauge is ejected out when anomaly appears in the drying oven and temperature is abnormally too high, a condition that the temperature of the drying oven is too high and exceeds the measuring range of the temperature gauge to cause burst is avoided, experimental cost is reduced, and safety of the experimental personnel is guaranteed.

Description

Technical field [0001] The invention relates to the field of drying ovens, and more specifically, is a laboratory drying oven based on the periscope temperature value of mirror multiple reflections. Background technique [0002] The laboratory drying oven must be temperature calibrated, that is, whether the set temperature of the drying oven and the actual temperature are within the standard range. Therefore, a thermometer needs to be inserted into the drying oven to measure the actual internal temperature in real time. However, the prior art laboratory uses The drying box has the following defects: [0003] 1. In order to read the temperature value easily, the thermometer cannot be inserted deep into the drying box. The temperature measured is the upper part of the drying box, which cannot represent the actual temperature in the drying box; In the drying box, when you want to read, you need to pull out the thermometer to read. At this time, the temperature will change, which will...

Problems solved by technology

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a laboratory drying box based on the multiple reflection periscope temperature value of the mirror surface, so as to solve the problem that the laboratory drying box of the prior art is convenient for reading the temperature value. The thermometer cannot penetrate into the drying box to a deep degree, and what is measured is the temperature of the upper part of the drying box, which cannot represent the actual temperature in the drying box; At this time, the thermometer needs to be pulled out to read, and the temperature will change at this time, which also affects the reading of the temperature value; sometimes there is an abnormality in the drying box, and its internal temperature exceeds the measurement range of the thermometer. At this time, the drying box cannot Automatically eject the thermometer, the thermometer may burst and increase the cost of the experiment. If a mercury thermometer is used, it may even endanger the safety of the experimenter.
