Abstract
The utility model discloses a kind of portable mask strainability test devices, including vacuum pump, spinner flowmeter, test container, mask and airborne particle counter；A kind of portable mask strainability test device of the utility model, structure is simple, and volume is light and handy, is convenient for carrying, and convenient for carrying out outdoor test, meets application requirement.
Description
Technical field
The utility model relates to public health medical domain, in particular to a kind of portable mask strainability test dress
It sets.
Background technique
In recent years, with the development of economy, China's air pollution is got worse, and most parts of the north are often by haze institute
It shrouds.The constituent of haze is sufficiently complex, including hundreds of Atmospheric Chemistry particulate matters.The partial size of particulate matter is smaller, in air
In degree of stability it is higher, sinking speed is slower, and the probability for being inhaled into respiratory tract is bigger.What is come into being is present market
Upper various types of masks, the effect of different types of mask protection and filtering is simultaneously different, then needs one kind simple and convenient
Mask filtering system safety testing device mask on the market is measured.
Utility model content
The purpose of this utility model is that defect according to prior art, provides a kind of portable mask strainability test
The technical solution of device, the portable mask strainability test device is achieved in that
A kind of portable mask strainability test device, including vacuum pump, spinner flowmeter, test container, mask and
Airborne particle counter；The vacuum pump is in the left end of device, and vacuum pump is a horizontal cylindrical body, and upper surface fixation is put
A spinner flowmeter is set, the upper port of spinner flowmeter and the air entry of vacuum pump are connected by snorkel, the rotor
The lower port of flowmeter is fixedly connected by snorkel with the left side of test container, and the test container is a cylindrical body,
Internal right side is placed mask, and lower surface is fixedly connected the dust particle of a cuboid by a snorkel
Device.
Further, the diameter of the test container is 40~60mm.
Working principle: portable mask strainability test device is tested outdoors is, starts vacuum pump, starts to simulate people
Body air-breathing can reflect air mass flow on spinner device, and mask is fixed in test container, and mask is in an atmosphere to particulate matter
Filterability can be calculated by dust particle collected inside the airborne particle counter of test container bottom.
A kind of portable mask strainability test device of the utility model, structure is simple, and volume is light and handy, conveniently takes
Band meets application requirement convenient for carrying out outdoor test.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the test device of the utility model；
Appended drawing reference: 1- vacuum pump, 2- spinner flowmeter, 3- test container, 4- mask, 5- airborne particle counter.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of portable mask strainability test device, including vacuum pump 1, spinner flowmeter 2, test
Container 3, mask 4 and airborne particle counter 5；For the vacuum pump 1 in the left end of device, vacuum pump 1 is a horizontal circle
Cylinder, upper surface fixed placement a spinner flowmeter 2, the upper port of spinner flowmeter 2 and the air entry of vacuum pump 1 pass through
Snorkel connection, the lower port of the spinner flowmeter 2 is fixedly connected by snorkel with the left side of test container 3, described
Test container 3 is a cylindrical body, and internal right side is placed mask 4, and lower surface is fixedly connected one by a snorkel
The airborne particle counter 5 of a cuboid.
When it is implemented, the diameter of the test container 3 is 40~60mm.
Further when it is implemented, the diameter of the test container 3 is 50mm.
Working principle: portable mask strainability test device is tested outdoors is, starts vacuum pump 1, starts to simulate
Human body air-breathing can reflect air mass flow on spinner device 2, and mask 4 is fixed in test container 3, and mask 4 is right in an atmosphere
The filterability of particulate matter can pass through dust particle collected by 5 the inside of airborne particle counter in 3 bottom of test container
It is calculated.
The technology contents and technical characteristic of the utility model have revealed that as above those skilled in the art still may base
In the utility model teaching and make the replacement and modification without departing substantially from the utility model in essence, therefore, the utility model protection
Range is not limited to the revealed content of embodiment, also includes various replacements and modification without departing substantially from the utility model in essence.
Claims (2)
