Abstract
The utility model provides a technical scheme of a water-injected pork detection device. The water-injected pork detection device comprises a shell and a circuit board fixedly arranged in the shell, wherein a direct-current power supply is arranged on the circuit board; an anode of the direct-current power supply is connected with a first probe through a switch; the switch is additionally connected with a collector of a first negative-positive-negative (NPN) type triode through a first light-emitting diode; a base of the first NPN type triode is connected with a second probe; a first resistor and a slide rheostat are connected in series between an emitter and the base of the first NPN type triode; the collector of the first NPN type triode is connected with a base of a second NPN type triode through a second resistor; an emitter of the second NPN type triode is connected with the emitter of the first NPN type triode; and a collector of the second NPN type triode is connected with the switch through a second light-emitting diode. The detection device adopting the scheme is simple and practical in structure, and whether water is injected into pork or not can be rapidly detected.
Description
Technical field
The utility model relates to a kind of pick-up unit that is used to detect water filling pork.
Background technology
At present, the Along with people's growth in the living standard, some illegal acts have also appearred in the meat market that dragons and fishes jumbled together; Especially pork, a lot of retailers inject a large amount of water for many interests in pork; And some retailer joins sewage in the pork; So not only damaged consumer's interests, also the body and mind to the consumer produces huge injury, and this is the existing in prior technology weak point.
Summary of the invention
The purpose of the utility model is exactly not enough to existing in prior technology, and a kind of technical scheme of water filling pork pick-up unit is provided; The pick-up unit of this scheme; Simple and practical, can detect whether water filling of pork fast, help people to discern water filling pork timely and effectively.
This programme is realized through following technical measures: a kind of water filling pork pick-up unit; Include housing; Be fixed on the circuit board in the housing; This programme characteristics are: said circuit board is provided with direct supply; The positive pole of direct supply is connected with first probe through a switch, and described switch also is connected with the collector of a NPN type triode through first light emitting diode, and the base stage of a described NPN type triode is connected with second probe; Series connection first resistance and a slide rheostat between the emitter of a said NPN type triode and the base stage; The collector of a described NPN type triode is connected with the base stage of the 2nd NPN type triode through second resistance, and the emitter of said the 2nd NPN type triode is connected with the emitter of a NPN type triode, and the collector of described the 2nd NPN type triode is connected with switch through second light emitting diode.
The beneficial effect of this programme can be learnt according to the narration to such scheme; Owing in this scheme, light emitting diode is arranged; Probe and relevant detection circuit when detecting water filling pork and not having the pork of water filling, have different lumination of light emitting diode; Help whether people's identification is water filling pork, the sensitivity that slide rheostat can adjusting gear.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the circuit diagram of the utility model embodiment.
Among the figure, 1 is housing, and 2 is circuit board.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below through an embodiment, and combine its accompanying drawing, this programme is set forth.
Can find out through accompanying drawing; The water filling pork pick-up unit of this programme; Include housing 1; Be fixed on the circuit board 2 in the housing 1, said circuit board 2 is provided with direct supply G, and the positive pole of direct supply G is connected with first probe A through a switch S; Described switch S also is connected with the collector of a NPN type triode VT1 through first LED 1; The base stage of a described NPN type triode VT1 is connected with second probe B, series connection first resistance R 1 and a slide rheostat Rp between the emitter of a said NPN type triode VT1 and the base stage, and the collector of a described NPN type triode VT1 is connected with the base stage of the 2nd NPN type triode VT2 through second resistance R 2; The emitter of said the 2nd NPN type triode VT2 is connected with the emitter of a NPN type triode VT1, and the collector of described the 2nd NPN type triode VT2 is connected with switch through second LED 2.During use, merge switch S, if water filling in the pork with two probe contact porks; A then NPN type triode VT1 conducting, first LED 1 is luminous, the reminds people water filling; If there is not water filling; The 2nd NPN type triode VT2 conducting, second LED 2 is luminous, and reminds people does not have water filling.
