Abstract
The utility model discloses a smell tester which comprises a plurality of testing units mounted on a shell body. The testing units are connected together in parallel, and each testing unit comprises an infrared light electric switch, a counter, a timer and a smell bottle. The infrared light electric switch is in a cylindrical shape and is connected at the top end of the smell bottle in a sleeved mode, a plurality of switch units connected in parallel are mounted around the inner portion of the infrared light electric switch, and each switch unit is formed by an emitting electrode and a receiving electrode arranged oppositely. The receiving electrode of each switch unit is connected with the counter and the timber in each testing unit. When the infrared rays in the switch units are cut off, the counters count once and the timers start timing. The smell tester can accurately record the hole probing time and hole probing times of a mouse, and misjudgment due to the fact that other parts of the mouse stretch into the tester is avoided through the design of a pedal type halt switch.

A kind of Olfactometry instrument, comprise a plurality of test cells that are arranged on housing, a plurality of described test cells are connected in parallel, each described test cell comprises Photoelectric infrared switch, enumerator, timer and abnormal smells from the patient bottle, described Photoelectric infrared switch is the cylindric described abnormal smells from the patient bottle top that is enclosed within, around described Photoelectric infrared switch inside, a plurality of switch elements that are connected in parallel are installed, each switch element consists of an emitter stage and a receiving pole staggered relatively, the described receiving pole of each of each test cell is connected with described timer with the described enumerator in this test cell, when the infrared ray in described switch element is truncated, described enumerator counts once timer and starts timing.
Further, each described switch element also comprises a probe display lamp, and this probe display lamp is arranged on described receiving pole, and when the infrared ray of certain described switch element is truncated, corresponding described probe display lamp is bright.
Further, each described test cell also comprises a passage display lamp and a channel switching, described passage display lamp is connected with described channel switching with after corresponding described Photoelectric infrared switch parallel connection, and when certain described channel switching is closed, corresponding described passage display lamp is bright.
Further, also comprise total power light, this total power light is in parallel with each described test cell, and when total power switch is closed, this total power light is bright.
Further, after each described test cell parallel connection, with the pause switch series connection, with total power switch, be connected again.
A kind of Olfactometry instrument of this utility model, guaranteed that to the use of HONGGUANG electric switch tester records mice inspecting hole time and number of times accurately, and the use of pause switch has been avoided stretching into because of other positions of mice the erroneous judgement that detector causes.
The accompanying drawing explanation
The master that Fig. 1 is a kind of Olfactometry instrument described in the utility model looks schematic diagram;
The schematic top plan view that Fig. 2 is a kind of Olfactometry instrument described in the utility model;
The circuit diagram that Fig. 3 is a kind of Olfactometry instrument described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is described in detail, the description of this part is only exemplary and explanatory, should any restriction not arranged to protection domain of the present utility model.
A kind of Olfactometry instrument as Figure 1-3, be arranged on a plurality of test cells 15 on housing, in the present embodiment we preferably 15,5 test cells 15 of 5 test cells be connected in parallel, each test cell 15 comprises Photoelectric infrared switch, enumerator 11, timer 12 and abnormal smells from the patient bottle 3.
Photoelectric infrared switch is cylindric abnormal smells from the patient bottle 3 tops that are enclosed within, and abnormal smells from the patient bottle 3 is arranged on its underpart erecting bed 5, and spring 4 is installed between abnormal smells from the patient bottle 3 and erecting bed.
The stainless steel faceplate 2 that has 5 holes is installed above Photoelectric infrared switch, and the position of these 5 holes is corresponding with the position of below Photoelectric infrared switch.
Around Photoelectric infrared switch inside, a plurality of switch elements that are connected in parallel are installed, the present embodiment is installed 9 switch elements, and each switch element consists of an emitter stage 161 and a receiving pole 162 staggered relatively,
Each receiving pole 162 of each test cell 15 all is connected with timer 12 with the enumerator 11 in this test cell 15, and when the infrared ray in switch element is truncated, corresponding counts device 11 counts once, and corresponding timer 12 starts timing.
Each switch element also comprises a probe display lamp 14,
This probe display lamp 14 is arranged on receiving pole 162, and when the infrared ray of certain switch element is truncated, corresponding probe display lamp 14 is bright, and whether this probe display lamp 14 can be used for detection probe can normally use.
Each test cell 15 also comprises a passage display lamp 10 and a channel switching 13,
Also comprise total power light 6, this total power light 6 is in parallel with each test cell 15, and when total power switch 17 is closed, this total power light 6 is bright.
