Description
Technical field
The utility model relates to a kind of air curtain, particularly is applicable to a kind of anti-mosquitos and flies automatic air curtain of inhabitation and workplace.
Technical background
As everyone knows, when in the mosquitos and flies inlet chamber, not only influence people's work, rest and sleep, and mosquito also can inhale the human blood communicate illness.In order to eliminate the mosquitos and flies in the inlet chamber, people use always and pat, kindle mosquito repellent incense, spray pesticide, Mosquito killer lamp, mosquito net or the like.Though these methods are effective, and unsurmountable drawback is also arranged.The good screen window of sealing generally all is equipped with in present inhabitation and workplace, and mosquitos and flies is can be by in its inlet chamber, the condition that indoor sanitary condition also can not cause mosquitos and flies to grow.Find that through long-time the observation mosquitos and flies especially mosquito all is the breath of following the person, be trapped among human body near, even climb on the person in people's inlet chamber.Does how overcoming the problems referred to above prevent in the mosquitos and flies inlet chamber? it is exactly a kind of effective method that air curtain is installed.But, existing air curtain is used for market, hospital, freezer and the big place of flow of personnel amount more, design is produced in order to prevent hot and cold air to run off, therefore volume is big, price is high, electricity consumption is many, in addition, in a single day this air curtain is opened, and turn round for a long time, thereby be not suitable for living and the workplace use.
Summary of the invention
The purpose of this utility model provides that a kind of volume is little, at the bottom of the price, power-saving, along with people open door, anti-mosquitos and flies air curtain is promptly opened automatically, along with people close door, anti-mosquitos and flies air curtain is promptly closed automatically.A kind of so normal discrepancy that does not promptly influence people can prevent automatic air curtain in the mosquitos and flies inlet chamber again.
The purpose of this utility model is achieved in that a kind of automatically anti-mosquitos and flies air curtain is characterized in that: this anti-automatically mosquitos and flies air curtain comprises the Air curtain machine that is installed in outdoors, switch or the very convenient gauge tap of handling that Air curtain machine is controlled are automatically formed, the prolongation of described Air curtain machine air outlet is the shape of shrinking the Rafael nozzle section that afterwards enlarges earlier, deep bead windward side in the described Air curtain machine is curved, and pairing string of this arc and draught fan impeller center are 45 °-89 ° to the angle folder of air outlet center vertical line.
Advantage of the present utility model is: one, the volume of air curtain is little, price is low, power-saving, and opens automatically along with the unlatching of door, closing and close automatically with door; The drawback of having brought when two, having overcome the worried and elimination that brings in the mosquitos and flies inlet chamber; Three, the prolongation of Air curtain machine air outlet is the shape of Rafael nozzle section, under the identical situation of other condition, the air outlet air velocity is improved; Four, the deep bead windward side design curved and angle in the Air curtain machine helps the air-flow slyness excessively, reduces eddy current and improves air velocity.
Description of drawings
Concrete structure of the present utility model and working condition are provided by following examples and accompanying drawing.
Accompanying drawing 1 is the structural representation of Air curtain machine 1;
Accompanying drawing 2 is that the motor 6 of Air curtain machine 1 closes 7 circuit of controlling by moving disconnection that automatically resets;
