Abstract
The utility model discloses a liquid level detecting needle and a liquid level detecting device, and aims to provide a liquid level detecting needle and a liquid level detecting device which are convenient to use and have improved detecting efficiency. The liquid level detecting device comprises an upper cover (1), a lower cover (2) matched with the upper cover (1), a circuit board (3) arranged in a cavity formed by the upper cover (1) and the lower cover (2) matched with each other, and a liquid level detecting needle (4) longitudinally arranged on the lower cover (2) and in contact with the circuit board (3); and the liquid level detecting needle (4) comprises an inner needle and an outer needle, and the space between the inner needle and the outer needle is sealed by epoxy resin. The liquid level detecting needle and the liquid level detecting device provided by the utility model can be widely used in the filed of medical instruments.
Description
Technical field
The utility model relates to a kind of level detection pin and liquid level sensor.
Background technology
At present, in Health Service Laboratory and hospital laboratory, people adopt the detection pin to come application of sample and sampling, handle with the method for sleeving plastic pipe with outer pin but existing detection pin is interior pin, adopt the principle of capacitive induction, the electric capacity of the pin that this method is handled changes easily, the consistance of pin and stability are poor, can not be equal to replacement in the test process of reality, use inconvenient, detection efficiency is low, and does not have visual indication to inform the user.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of easy to use, the level detection pin and liquid level sensor that can improve detection efficiency is provided.
The technical scheme that a kind of level detection pin of the utility model is adopted is: pin and outer pin in described level detection pin comprises, adopt epoxy resin to fill out envelope between described interior pin and the described outer pin
The technical scheme that a kind of liquid level sensor of the utility model is adopted is: a kind of liquid level sensor of the utility model comprises loam cake, the lower cover that matches with described loam cake, be positioned at described loam cake and described lower cover match form the wiring board of cavity, vertically be arranged on cover under described and with the contacted described level detection pin of described wiring board, pin and outer pin in described level detection pin comprises adopt epoxy resin to fill out envelope between described interior pin and the described outer pin.
Optimize, a kind of liquid level sensor of the utility model also comprise be arranged on described loam cake or described under cover and with the contacted LED light of described wiring board,
The beneficial effects of the utility model are: because the utility model comprises the level detection pin, pin and outer pin in described level detection pin comprises, adopt epoxy resin to fill out envelope in described between pin and the described outer pin, adopt the electric capacity of the pin of this mode to be not easy to change, the consistance of pin and stability are relatively good, can be equal to replacement in the test process of reality, and is easy to use, can effectively improve detection efficiency, so the utility model is easy to use, can improve detection efficiency.
Because described loam cake or described lower cover are provided with LED light, described LED light is electrically connected with described wiring board, the detected information of described detection pin can pass to described LED light by described wiring board, for people provide indication, so the utility model is indicative more directly perceived.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a blast structural representation of the present utility model.
Embodiment
As Fig. 1, shown in Figure 2, the utility model comprises loam cake 1, the lower cover 2 that matches with described loam cake 1, be positioned at the wiring board 3 of the cavity that described loam cake 1 and described lower cover 2 match, vertically be arranged on the described lower cover 2 and with described wiring board 3 contacted level detection pins 4, pin and outer pin in described level detection pin 4 comprises, adopt epoxy resin to fill out envelope in described between pin and the described outer pin, adopt this processing mode pin consistance and stability relatively good, in the process of practical application, can be equal to replacement, do not need adjustment circuit repeatedly, easy to use and effective, can effectively improve the efficient of detection, and described loam cake 1 or described lower cover 2 are provided with LED light 5, described LED light 5 is electrically connected with described wiring board 3, described level detection pin 4 detected information are delivered to described LED light by described wiring board 3, are using to obtain relatively visual indication.
The utility model can be widely used in field of medical.
