Description

Technical Field

[0001] The utility model relates to a temperature and humidity measuring device, and more particularly to a temperature and humidity measuring instrument based on e-ink screen display. Background Technique

[0002] There are many very small "microcapsules" attached to the surface of the e-ink screen, which encapsulate black particles with negative charges and white particles with positive charges. By changing the charge, different colored particles are arranged in an orderly manner, thus presenting a clear black and white visualization effect. Power saving is a major feature of the e-ink screen. After the text is refreshed, it will stay on the screen for a long time, and the battery can be removed during reading. In other words, the e-ink screen does not consume power during reading and only consumes power when turning the page and refreshing.

[0003] Therefore, using an e-ink screen for display in a temperature and humidity measuring device can effectively extend the overall usage time and reduce power consumption. However, the temperature range of the e-ink screen is usually between 0°C and 50°C. Sometimes, the temperature difference measured by the temperature and humidity measuring device is relatively large, which may cause abnormal display of the e-ink screen. Summary of the Invention

[0004] The purpose of the utility model is to provide a temperature and humidity measuring instrument based on e-ink screen display to solve the problems raised in the above background technique.

[0005] A temperature and humidity measuring instrument based on e-ink screen display includes a rear cover body. In the middle of the inner cavity of the rear cover body, an isolation board is fixedly installed. In the middle of the front side of the isolation board, a main control unit is fixedly installed.

[0011] Furthermore, a connection slot is fixedly installed in the middle of the front side of the main control unit, and a connection plug is fixedly installed above the middle of the rear side of the ink screen housing. The connection plug and the connection slot can be inserted and connected.

[0012] By adopting the above technical solution, after the connection plug is inserted into the connection slot, the ink screen body is connected to the main control unit, enabling the ink screen body to immediately display the content recorded by the main control unit.

[0013] Furthermore, a connection groove is opened in the front side of the upper end of the rear cover body, limit grooves are opened on both sides of the connection groove at the upper end of the rear cover body, and limit slots are fixedly installed on the front side of the rear cover body at the positions of the limit grooves. A limiting member corresponding to the limit slot is provided on the rear side of the ink screen housing.

[0014] By adopting the above technical solution, the limiting members on both sides can be inserted into the corresponding limit slots. The limiting members play a certain supporting role and can avoid the shaking of the connection.

[0015] Furthermore, a vacuum groove is provided in the middle of the heat-insulating glass.

[0016] By adopting the above technical solution, the heat-insulating glass has a good heat-insulating effect and can reduce the influence of the external temperature on the display effect of the ink screen body.

[0017] Furthermore, the ventilation grooves are symmetric on both sides, and the main control unit is electrically connected to the temperature and humidity sensing chip, the data interface, and the connection slot respectively.

[0018] By adopting the above technical solution, the ventilation grooves can increase the ventilation effect. When air enters the inside of the rear cover body from the position of the ventilation grooves, the temperature and humidity sensing chip will detect the temperature and humidity of the air.
