Embodiment Construction

[0004] Scheme 1: After the surface can be made conductive by spraying, a thin metal layer of a certain thickness can be plated by electroplating. Such as copper, tin or zinc. Or adopt other more feasible process technologies, in short, pursue low cost under the premise of meeting the design requirements.

[0005] Option 2: Use the method of covering plastic film. The same principle as scheme 1 can play a protective role. The proper thickness of the film through testing will not affect the normal measurement of body temperature by the thermometer. The key is whether a feasible process can be found to make the plastic film adhere to the surface of the thermometer.

[0006] The technical points are:

[0007] 1. The thin layer protecting the mercury bulb must be tightly wrapped around the mercury bulb to ensure good heat conduction.

[0008] 2. Determine the appropriate coating thickness through experimental tests to ensure good thermal conductivity of the mercury bulb and no...

Abstract

The invention relates to a mercury-leakage-resistant thermometer which is used for daily life and medical service. The common thermometer has the defects that the mercury bulb part of the thermometer is extremely easy to smash; the mercury after being smashed is not easy to collect and clean up; the mercury which remains in a room is slowly and completely volatilized in the air; and the mercury stream is exactly the main reason of mercurialism. Because the common thermometer influences the health of people because of the reason of the mercurialism, particularly the health and intelligence development of children, parents are increasingly worried about the problem. The mercury-leakage-resistant thermometer provided by the invention solves the problem that the common thermometer influences the health and intelligence development of the children. The mercury-leakage-resistant thermometer provided by the invention is characterized in that the mercury bulb part of the thermometer is tightly wrapped by metals, thereby protecting the mercury bulb part which is the easiest smashed part of the thermometer and avoiding the mercury from leaking after the mercury bulb is smashed. If the other parts are smashed, the mercury does not leak because the mercury column is thin. Simultaneously, the heat conduction of the mercury bulb part is not influenced, and the indication of the part with scales is not influenced.

Description

technical field [0001] The invention is used in daily life and medical services, and is specifically a thermometer. Background technique [0002] The disadvantage of ordinary thermometers is that the mercury bulb part of the thermometer is very easy to break, and it is not easy to collect and clean up the mercury after it is broken. If the mercury cannot be cleaned indoors, it will slowly volatilize into the air. reason. Contents of the invention [0003] My idea is to tightly wrap the mercury bulb part of the thermometer with metal, so as to protect the most fragile part of the thermometer - the "mercury bulb", and prevent the mercury from leaking after the mercury bulb is broken. When other parts are broken, the mercury will not leak out because the mercury column is very thin. At the same time, this will not affect the heat conduction of the mercury bulb, nor will it affect the reading of the graduated part. detailed description [0004] Scheme 1: After the surface...
