Abstract
The utility model relates to a safe-guard door with a wind screen, comprising a door frame, a door arranged in the door frame and a blower arranged on the door frame. The safe-guard door is characterized in that the joint of the door and the door frame is provided with an inductive switch. Compared with the prior art, the safe-guard door can prevent outdoor mosquitoes and flies from flying indoors after being opened enabling the blower to be automatically started to form the wind screen; moreover, the inductive switch is sensitive and simple in structure.
Description
Technical field
The utility model relates to a kind of security door that prevents function in outdoor mosquitos and flies and the dust inlet chamber that has.
Background technology
Raising along with modern life level, people are more and more higher to the requirement of life comfort level, but the invasion of mosquitos and flies is the puzzlement that the modern life can't be broken away from, although people take method such as screen window to prevent that outdoor mosquitos and flies from entering, but can't prevent that outdoor mosquitos and flies from entering from the security door of opening, because the number of times of security door unlatching every day is a lot, and mosquitos and flies quite a lot is entered from security door in the air, has brought no small worry for many families.
Summary of the invention
The present invention will make security door have concurrently and prevent the function that outdoor mosquitos and flies and dust enter.The present invention adds blast apparatus (blower fan) and inductive switch on the basis of security door, this blast apparatus (blower fan) can produce the air-flow of certain speed, in the doorframe scope, form parallel with doorframe or outside at a certain angle air curtain, thereby effectively prevent entering of outdoor mosquitos and flies and dust.When security door is opened,, make the power connection of blower fan, thereby start blower fan, the formation air curtain by being installed in door and the induction installation of doorframe junction such as infrared, contact induction switch etc.; When security door cuts out,, make the power supply disconnection of blower fan, thereby close blower fan by being installed in the door and the induction installation such as infrared, the contact-making switch of doorframe junction.In order to play best effect, blower fan can be placed in any side or many sides of doorframe.
Consider that the user generally is the needs that anti-mosquitos and flies was just arranged in summer, and to take the needs that conveniently use and fit up into account, blower fan also can be fixed on the doorframe of security door by acceptable dismountable fixed forms such as screw or hooks, power line on the blower fan and power connection, but joint and the induction installation on the security door by plug carry out the signal conduction, or induction installation directly placed on the blower fan, make the blower fan can be for convenience detach and install, do not influence the use of security door.
The beneficial effects of the utility model are to solve the problem that common security door can't stop that mosquitos and flies and dust enter.Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings
Fig. 1 is a structure chart of the present utility model
Fig. 2 is the dismounting schematic diagram
Fig. 3 is a circuit diagram
Among the figure: but 1-blower fan, 2-power switch, 3-air outlet, 4-inductive switch, 5-air curtain, 6-doorframe, 7-door, 8 attaching plugs, 9-blower fan fixing threaded hole, 10-doorframe fixing threaded hole, the connector receptacle of 11-plug, 12-blower motor
The specific embodiment
The utility model comprises doorframe (6), is arranged on the door (7) on the doorframe (6), and its special feature is that the raft of pontoons on the doorframe (6) in door has blast apparatus (1), is provided with inductive switch (4) in door (2) and doorframe (1) junction.
Blower fan (1) is connected power supply by attaching plug (8), when power switch (2) is connected, blower fan (1) is by the folding interlock of inductive switch (4) with door (7), when door (7) when opening, doorframe (6) is gone up the inductive switch of installing (4) and is connected, and makes the power connection of blower fan (1), thereby starts blower motor (12), form air curtain (5) from air outlet (3), prevent entering of outdoor mosquitos and flies and dust; When door (7) when closing, inductive switch (4) disconnects, and makes the dump of blower fan (1), thereby closes blower fan (1).
Blower fan (1) can be placed in any side or many sides of doorframe (6).
Blower fan among the present invention (1) is designed to can be for convenience detach and the form of installing, blower fan (1) is fixed on the doorframe fixing threaded hole (10) of doorframe by blower fan fixing threaded hole (9), blower fan (1) but inductive switch (4) UNICOM on connector receptacle (11) by plug and the security door, make the blower fan can be for convenience detach and install, do not influence the use of security door.
Claims (4)
1, a kind of security door that has air curtain comprises doorframe (6), is arranged on the door (7) on the doorframe (6), is fixed on the blower fan (1) on the doorframe (6), it is characterized in that the door (7) and the junction of doorframe (6) are provided with inductive switch (4).
2, the described security door of claim 1 is characterized in that described inductive switch (4) is infrared or contact induction switch.
3, claim 1 or 2 described security doors is characterized in that described blower fan (1) is fixed on the doorframe with screw or hook.
4, claim 1 or 2 described security doors is characterized in that described blower fan (1) is fixed on either side or many sides of doorframe (6).
