Abstract
On existing condenser type water measuring apparatus, the utility model is allocated with a cigarette moisture sensor which is formed by two electric poles and a shelf of cigarette sample placed between the two electric poles. The sensor is connected with a capacitance measurement circuit, a single chip computer system, a temperature measurement cancelling circuit and a displaying device. The electric capacitance of the sensor is converted into humidity of cigarette and is displayed on screen by digit. The sensor can be made of an internal electrode of circular column, an outer electrode of ring cover and a shelf of sample of a non-metal ring cylinder. The sensor can also be formed by two plate electrodes and one shelf of sample of rectangle box. The utility model does not need to tear open cigarette at the time of measuring water of cigarette. It is convenient in use. The measuring is quick. The display is intuitional.
Description
The utility model belongs to the cigarette moisture determinator.
Measure the moisture content of cigarette now, need strip out pipe tobacco, measure its water cut with oven dry constant weight method or other method then.Existing condenser type aquametry apparatus, as grain aquametry apparatus or tea moisture measuring instrument, when being used to measure cigarette moisture, also need to strip out pipe tobacco, weigh in the balance and measure its water content again after getting constant weight, complex operation, minute is long, is unfavorable for the quality check in production of cigarettes, storage and the trade process.
The purpose of this utility model is a kind of device of measuring cigarette moisture fast, accurately, easily of design, need not to tear open the stripping pipe tobacco, and the cigarette of some is put into the specimen holder of this measurement mechanism, promptly reads the water content of cigarette on screen.
The utility model is to improve to design on existing condenser type aquametry apparatus basis.Two electrodes and place the cigarette sample between it to be configured to the cigarette moisture sensor.The capacitance measurement circuit of this sensor and former condenser type aquametry apparatus, Single Chip Microcomputer (SCM) system, the temperature survey compensating circuit, display circuits etc. link.Same specification, the various types of cigarette shreds weight of identical number is basic identical, props up as long as put into the cigarette of some in the cigarette moisture sensor, just the electric capacity of sensor can be converted to cigarette moisture content, shows with numeral on screen.It is cylindrical interior electrode that the electrode of cigarette moisture sensor can be made into one, and another is sleeved external electrode, and specimen holder is for placing the ring-shaped sleeve between two electrodes.Sensor electrode also can adopt two parallel plate electrodes, and specimen holder is the rectangle square box that places therebetween.Specimen holder is made with nonmetallic materials, can be partitioned into hole slot in it, so that place cigarette.
When cigarette moisture measuring instrument of the present utility model is measured cigarette moisture, need not to tear open the damage cigarette, need not day an equality Other Instruments or an instrument.Need only the sample sensor frame of the cigarette of some being put into this measuring instrument, need not other operation, directly on screen, show water content immediately.Be easy to use, simple to operate.Avoided the manual operation error, the result is accurate, good reproducibility.Numeral clear display, directly perceived.Be adapted at various occasions cigarette is carried out the water content inspection.
The following drawings illustrates embodiment of the present utility model.
Fig. 1 is the cigarette moisture sensor longitudinal diagram of the utility model embodiment 1.
Fig. 2 is the cigarette moisture sensor drawing in side sectional elevation of the utility model embodiment 1.
Fig. 3 is the cigarette moisture sensor longitudinal diagram of the utility model embodiment 2.
Fig. 4 is the cigarette moisture sensor drawing in side sectional elevation of the utility model embodiment 2.
Describe structure of the present utility model in detail below in conjunction with accompanying drawing.
Embodiment 1 is shown in accompanying drawing 1,2.Electrode (1) is the metal cylinder of diameter 8-25mm among the figure, and external electrode (2) is the metal ring set of internal diameter 25～85mm, and two electrode height are 75～160mm.Two electrodes are placed with one heart, between distance 85～30mm, can fix the relative position of two electrodes in the bottom with the pillar of nonmetallic materials (3).Specimen holder (4) is nonmetallic materials, and as the ring-shaped sleeve of organic glass, internal diameter is 81～251mm, and external diameter is 249～849mm, highly is 5～70mm.Specimen holder (4) can insert between two electrodes or extract out.For the ease of placing cigarette, can the equispaced between specimen holder (4) inside and outside wall, form wide or diameter 8.4～20 of the hole slots of 1～28mm.Cigarette (5) places in the specimen holder, can put into hole slot, and specimen holder (4) inserts between the internal and external electrode and detects.For the ease of specimen holder (4) is taken out, handle (6) is housed at an end of specimen holder between two electrodes.
Two contact conductors (7) of the cigarette moisture sensor in accompanying drawing 1 and the accompanying drawing 3 and Circuits System link, and adjust Single Chip Microcomputer (SCM) system according to test figure, make the capacitance values of cigarette moisture sensor be converted to cigarette moisture content and show with numeral on screen.
