For realizing the utility model object, the utility model provides a kind of portable second-hand-cigarette purifier, person easy to use carries with and can carry out effective purified treatment to the second-hand-cigarette in surrounding environment, works the mischief to the healthy of user to avoid second-hand-cigarette.
As shown in Figure 1, Fig. 1 is the structural representation of the portable second-hand-cigarette purifier of the utility model preferred embodiment in a state of use.In the present embodiment, described portable second-hand-cigarette purifier 1 include but not limited to, hollow tube 10, air intake cylinder 11, air blast 12, flue gas cleaner 13, exhaust blower 14 and exhaust tube 15.Described air intake cylinder 11 is connected to one end of hollow tube 10, and exhaust tube 15 is connected to the other end of hollow tube 10.Described air blast 12 is arranged in air intake cylinder 11, for making air import hollow tube 10 from air intake cylinder 11 by air blast mode.Described flue gas cleaner 13 is fixed in hollow tube 10, for carrying out filtration, purification to the second-hand-cigarette in hollow tube 10, absorbs harmful substance and the carcinogen such as tar, nicotine, suspended particulates in second-hand-cigarette.Described exhaust blower 14 is arranged in exhaust tube 15, for being discharged for user's tidal air from exhaust tube 15 by purified gas by exhaust way.
The material of described hollow tube 10 can be made up of light-weight metal, plastic material, bakelite material or these material adapteds, and its profile can be cylindrical shape or square tube shape, also can be the profile with handicraft character, such as flashlight shape.If described hollow tube 10 is cylindrical, the length of this hollow tube 10 is generally 15cm to 20cm, and diameter is generally 3cm to 5cm; If described hollow tube 10 is in square tube shape, the length of this hollow tube 10 is generally 15cm to 20cm, and wide is 3cm to 5cm, and height is 3cm to 5cm.Due to the small volume of hollow tube 10, thus person easy to use carries with to outdoor or public arena use.
Described air intake cylinder 11 adopts the material of material identical with hollow tube 10 to make, and one end of this air intake cylinder 11 and one end size of hollow tube 10 match, and the other end makes fan-shaped mouth shape, is convenient to suck extraneous air.Described exhaust tube 15 also adopts the material of material identical with hollow tube 10 to make, one end of this exhaust tube 15 and one end size of hollow tube 10 match, it is the bell mouth shape that can cover user's face and nose areas that the other end makes a size, is convenient to user and face and nose are carried out tidal air near exhaust tube 15.
Described air blast 12 is arranged in air intake cylinder 11, for making extraneous air import hollow tube 10 from air intake cylinder 11 by air blast mode.Described exhaust blower 14 is arranged in exhaust tube 15, for being discharged from exhaust tube 15 by purified gas by exhaust way.Described air blast 12 and exhaust blower 14 are connected on minicell 16, this minicell 16 is for providing working power to described air blast 12 and exhaust blower 14, this minicell 16 is rechargeable batteries of a kind of Low emissivity, low-power consumption, and it can not bring impact to the health of user.In the present embodiment, this minicell 16 is also connected with a charging port 17, this charging port 17 can be the battery charging inlet of a kind of USB interface or other standard, and this charging port 17 directly can insert on external power source (such as computer USB interface or low pressure voltage-stablizer etc.) and charge to described minicell 16.When the electricity of described minicell 16 is finished, user charges by described charging port 17 pairs of minicells 16, thus extends the life cycle of described portable second-hand-cigarette purifier 100.
Described flue gas cleaner 13 is fixed in hollow tube 10, for carrying out filtration, purification to the second-hand-cigarette in hollow tube 10.Described flue gas cleaner 13 comprises grit filter 131 and pneumatic filter 132.Described grit filter 131 is made up of filter materials such as a kind of non-woven fabrics, glass fibre, chemical fibre, nylon wire or nanofiber filter paper, for filtering the harmful substance such as flue dust, suspended particulates in second-hand-cigarette.Described pneumatic filter 132 is made up of a kind of active carbon of strong adsorption capacity, for adsorbing the carcinogen such as tar, nicotine in second-hand-cigarette.
The inwall of described exhaust tube 15 is provided with infrared sensor 18, produces the signal of telecommunication control described air blast 12 and exhaust blower 14 rotates for sensor light signal.Such as, when the face of user and the close exhaust tube 15 of nose, thus the optical signal making infrared sensor 18 can receive human body to reflect, and this optical signal changes the signal of telecommunication into through infrared sensor 18 process, and by the electrical signal transfer after transformation to exhaust blower 14, exhaust blower 14 starts to rotate according to the signal of telecommunication received, and makes second-hand flue gas can obtain adsorption cleaning by flue gas cleaner 13 efficiently; When the face of user and nose leave exhaust tube 15, infrared sensor 18 does not receive the optical signal reflected, so infrared sensor 18 sends one stop the signal of telecommunication, and this stopping electrical signal transfer being slowed down rotation to exhaust blower 14, thus the electricity consumption of minicell 16 can be saved.
In the present embodiment, described portable second-hand-cigarette purifier 1 also comprises second-hand-cigarette sensor 21 and alarm 22, and this second-hand-cigarette sensor 21 and alarm 22 are separately positioned on air intake cylinder 11 inwall.Second-hand-cigarette concentration in described second-hand-cigarette sensor 21 detecting real-time user surrounding air, when the second-hand-cigarette concentration in surrounding air is greater than preset value, alarm 22 sends the warning message of second-hand-cigarette concentration over-standard in a surrounding air, uses the second-hand-cigarette in the portable second-hand-cigarette purifier 1 pair of surrounding air carried with to purify to point out user.
Shown in composition graphs 2, Fig. 2 is the structural representation of the portable second-hand-cigarette purifier of the utility model preferred embodiment under unused state.In the present embodiment, described air intake cylinder 11 and exhaust tube 15 adopt telescopic connection structure with the connection at hollow tube 10 two ends.That is, when user does not use portable second-hand-cigarette purifier 1 to carry out second-hand-cigarette purification, described air intake cylinder 11 and exhaust tube 15 can shrink in hollow tube 10 along hollow tube 10 two ends respectively, thus person easy to use carries with; When user uses this portable second-hand-cigarette purifier 1 to carry out second-hand-cigarette purification, air intake cylinder 11 can be extracted out in hollow tube 10 and use.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent function conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
