The utility model has the advantages that: the problem that the liquid level is detected by manual auxiliary operation in the traditional method is solved through the structure for detecting the weight of the reagent and measuring the liquid level of the reagent, the problem that the reagent is polluted by the traditional contact sensor is also solved, the installation is simple, and the production cost is low.
Description
Technical Field
The utility model relates to a medical treatment and sanitation equipment, especially a liquid level auxiliary detection device of reagent kettle.
Background
Reagent liquid level detection is a common function on biochemical equipment, and the liquid level of a reagent cannot be detected, so that the reagent cannot be sensed when the reagent is insufficient in the experimental process, and the experiment fails. The touch sensor sensing structure used in the market can cause reagent residue or pollution, and the non-touch sensor structure is not sensitive to liquid reagent detection and is easy to detect errors.
Disclosure of Invention
The utility model provides a liquid level detection device of reagent kettle for solve above-mentioned defect, solved the problem that the tradition needed artifical auxiliary operation to detect the liquid level through the structure of detect reagent weight measurement reagent liquid level, also solved the problem that traditional contact sensor leads to reagent to pollute, the installation is simple, low in production cost is realized through following technical scheme.
The utility model provides a liquid level detection device of reagent kettle, reagent kettle pass through the reagent tray and press in weighing sensor one end, and weighing sensor's the other end is fixed in the backup pad, the reagent tray is U font tray frame, weighing sensor still is including the interface that is used for exporting the signal of telecommunication.
Furthermore, the supporting plate is a support shaped like a Chinese character 'ji', and a plurality of screw holes are formed in the supporting plate.
The utility model has the advantages that: the problem that the liquid level is detected by manual auxiliary operation in the traditional method is solved through the structure for detecting the weight of the reagent and measuring the liquid level of the reagent, the problem that the reagent is polluted by the traditional contact sensor is also solved, the installation is simple, and the production cost is low.
Drawings
Fig. 1 is a schematic structural diagram of a detection device in an embodiment of the present invention.
Fig. 2 is a schematic side view of the detecting device in the embodiment of the present invention.
Fig. 3 is another schematic structural diagram of the detecting device according to the embodiment of the present invention.
Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
As shown in figures 1-3, a liquid level auxiliary detection device of a reagent pot, a reagent pot 1 is pressed at one end of a weighing sensor 3 through a reagent tray 2, the other end of the weighing sensor 3 is fixed on a supporting plate 4, the reagent tray comprises a baffle 21 with three sides to form a tray frame with a U-shaped structure 22, the baffle can adopt a welding connection or an integrated forming mode, and then is fixed at the edge of the tray through welding or other connection modes. The embodiment of the utility model provides a simple structure, simple to operate.
The supporting plate 4 is a support shaped like a Chinese character 'ji', a plurality of screw holes 41 are arranged on the supporting plate, the screw holes on two sides of the supporting plate are used for fixing the supporting plate on other equipment or a workbench, and the screw holes in the middle of the supporting plate are used for fixing the weighing sensors 3.
The weighing sensor 3 further comprises an interface 31 for outputting an electrical signal, such as an RS232 interface, connected to a computer serial interface peripheral. When in detection, the weight of the reagent pot is converted into an electric signal of the weight through an AD chip in the weighing sensor, and then the electric signal is input into a computer or other equipment with a calculation function through the interface 31. The computer combines liquid density through liquid weight in the reagent kettle, calculates liquid volume in the kettle earlier, obtains the liquid level height with the bottom surface area of kettle again, because the specification of reagent kettle is the same, and its bottom surface area is the fixed value, because computational formula needs the computer to carry out, consequently the utility model discloses a device is for auxiliary computer obtains the liquid level height value, and how the computer calculates, does not belong to the utility model discloses a protection scope, here do not describe in detail.
Adopt utility model's scheme, need not go to open the reagent kettle, the rethread liquid level measurement chi stretches into the height of going to measure liquid in the kettle, causes the pollution. For example, the liquid level may be contaminated by a contact sensor, such as a water level meter, in the reagent bottle. Therefore, the technical scheme of the embodiment can solve the technical problem of pollution caused by direct measurement in the field.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
