Abstract
The utility model relates to a free-swing linical thermometer without mercury, belonging to the medical supplies, and comprising a casing with a liquid storage cavity at the lower end, a show channel which is communicated with the liquid storage cavity at the upper end. The utility model includes the technical proposal as follows: a check valve that the valve core is magnetic is arranged between the liquid storage cavity and the show channel; when in use, the valve core of the check valve makes backward movement through utilizing the magnetic force to open the check valve, then, the utility model returns to the initial condition; and the thermometer with the structure above is capable of making the display material is made of the materials such as alcohol which has added the red pigment. The utility model has the advantages of reducing the cost of the thermometer on one hand, and making the display clearer and the reading easier on the other hand; in addition, once damaged, the thermometer is incapable of polluting the ambient environment.
Description
Affiliated technical field
The utility model is a kind of no mercury free-swing type clinical thermometer, belongs to a kind of medical supplies.
Background technology
Present clinical thermometer generally is display material with mercury, and its reading is not easy on the one hand, and on the other hand, clinical thermometer is because of being caused mercury pollution to environment after the breakage accidentally.
Summary of the invention
The purpose of this utility model is: design a kind of no mercury free-swing type clinical thermometer that can use common liq to do display material.
The utility model comprises that the lower end has the housing of liquid storage cylinder, display channel that top has to communicate with liquid storage cylinder, and its technical scheme is: have a spool to have the retaining valve of magnetic between liquid storage cylinder and the display channel.During use,, can with magnetic force the spool of retaining valve be run back the utility model if clinical thermometer will be got back to original state, and with one-way valve opens.After the utility model is designed to this structure, can use other material to do display material as the alcohol that adds red pigments etc.The cost of clinical thermometer is reduced, make on the other hand that its demonstration is more clear, reading is easier, in addition, in case the clinical thermometer breakage can not pollute surrounding environment yet.
The structure of the utility model retaining valve reaches can adopt following structure with cooperating of housing: the lower end of display channel has and display channel spool bore at angle, and the retracing spring that cooperates with spool is housed in the hole.Spool of the present utility model can also can make its position with the liquid storage cylinder liquid outlet relative in any position of display channel bottom, and spool cooperates with the liquid storage cylinder liquid outlet.At this moment the lower end of liquid storage cylinder liquid outlet and spool can be the back taper that matches.And the upper end size of back taper is more preferably greater than the size of spool bore.
