Abstract
The utility model discloses a floating bacteria sampler, and relates to the technical field of detection instruments. The floating bacteria sampler comprises a shell body, a sampling head, a culture dish tray, an upper fan, a motor and a lower fan, wherein the sampling head is arranged in the shell body; the culture dish tray is arranged below the sampling head; the upper fan is arranged below the culture dish tray; the motor is connected below the upper fan; the lower fan is connected below the motor; an air outlet is formed in the lower end of the shell body; an air suction opening is formed between the culture dish tray and the upper fan; ventilation openings are formed in two sides of the sampling head; the upper fan and the lower fan are driven by the motor; the upper fan and the lower fan are rotated in the same direction and exhaust in the same direction. According to the floating bacteria sampler, double fans are operated in opposite directions at the same time, so that the speed and the flow of inlet air and outlet air are greatly improved, the requirement of 10.8 m/s is met easily, the load of a single fan is greatly reduced, the overall service life of the sampler is prolonged, and moreover, the capture efficiency of microorganisms is greatly improved.
Description
Technical field:
The utility model relates to detecting instrument technical field, is specifically related to a kind of borne bacteria sampler.
Background technology:
Aerial bacterioplankton sampling thief is a kind of porous inhaling type sampling thief efficiently, it is based on Anderson collision theory, the getter device of instrument sucks air by porous sampling head, strike on culture dish, airborne microorganism is " trapped " on nutrient agar, this instrument can be widely used in pharmaceutical industry, foodstuffs industry, beverage tap water, medicine inspecting institute, health and epidemic prevention, hospital, the industries concerneds such as public place and department, but existing borne bacteria sampler volume and power are all less, reach the requirement of air impact speed 10.8m/s, just require the running of the large load of blower fan, so long-time use will be accelerated the damage of blower fan, reduce the work-ing life of blower fan, thereby also greatly reduced in the life-span of sampling thief.
Utility model content:
The purpose of this utility model is to provide a kind of borne bacteria sampler, and it adopts the oppositely running simultaneously of two blower fans, has greatly improved turnover gas speed flow, is easy to reach the requirement of 10.8m/s, greatly reduces the load of a blower fan, has improved the bulk life time of sampling thief.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises housing, sampling head, culture dish pallet, fan, motor, lower blower fan, in described housing, be provided with sampling head, sampling head below is provided with culture dish pallet, culture dish pallet below is provided with fan, fan below is connected with motor, motor below is connected with lower blower fan, housing lower end has air outlet, between described culture dish pallet and fan, be provided with suction opening, described sampling head both sides are provided with ventilation opening, described fan and lower blower fan are by driven by motor, fan and lower blower fan rotating in same direction, air draft in the same way.
Described ventilation opening below is provided with a centroclinal baffle plate.
It adopts the oppositely running simultaneously of two blower fans the utility model, greatly improve turnover gas speed flow, be easy to reach the requirement of 10.8m/s, greatly reduced the load of a blower fan, improve the bulk life time of sampling thief, and greatly improved the capture rate of microorganism.
Brief description of the drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
Referring to Fig. 1, this embodiment is by the following technical solutions: it comprises housing 1, sampling head 2, culture dish pallet 3, fan 4, motor 5, lower blower fan 6, in described housing 1, be provided with sampling head 2, sampling head 2 belows are provided with culture dish pallet 3, culture dish pallet 3 belows are provided with fan 4, fan 4 belows are connected with motor 5, motor 5 belows are connected with lower blower fan 6, housing 1 lower end has air outlet 7, between described culture dish pallet 3 and fan 4, be provided with suction opening 8, described sampling head 2 both sides are provided with ventilation opening 9, ventilation opening 9 belows are provided with a centroclinal baffle plate 10, described fan 4 all has motor 5 to drive with lower blower fan 6, fan 4 and lower blower fan 6 rotating in same directions, air draft in the same way.When the utility model work, after electric motor starting, drive fan and the running of lower blower fan simultaneously, fan and lower blower fan rotating in same direction, air draft in the same way, therefore the overall air draft flow of blower fan improves greatly, also reduced motor current consumption simultaneously, be easy to just can reach the requirement of air impact speed 10.8m/s, improve the bulk life time of sampling thief, the centroclinal baffle plate that sampling head ventilation opening below arranges in addition, can make the most of microorganism in sampling head first strike with the wind culture dish pallet, wherein microorganism is hunted down, then wind rebounded after through baffle plate downside by blower fan sucking-off, therefore greatly improved the capture rate of microorganism.
