Technical Field
The utility model relates to the technical field of air curtains, in particular to an automatic upward blowing type air curtain.
Background
In the pharmaceutical production process, the production workshop and the warehouse for storing raw materials have high requirements on sanitary conditions, are isolated from outside air and are insect-proof and mosquito-proof, so that air curtains are installed on doors of the production workshop and the warehouse. The existing air curtain usually consists of an air treatment device, a ventilator, an air pipe system and an air distributor, is generally arranged above a door, and sends out curtain-shaped airflow with certain speed, certain temperature and certain thickness through strip-shaped nozzles to cut off the airflow outside the door. In the prior art, the direction of air blown out by an air curtain blows downwards, the effective height of the air blown from top to bottom is only about 1 meter, the downward wind force is smaller, the power of an air curtain fan is generally only 300 watts, and if the power of the fan is increased, the noise of the air curtain is too large. For the convenience of loading and unloading goods by a large vehicle, the height of the raw material warehouse door is higher and generally exceeds 2 meters, so that the conventional air curtain cannot completely block air flow and prevent insects and mosquitoes, and air and mosquitoes outside the door can enter a production workshop and a raw material warehouse from the lower part of the door frame to influence production.
SUMMERY OF THE UTILITY MODEL
Aiming at the problems in the prior art, the utility model aims to provide an automatic upward blowing type air curtain, the blowing direction of the air curtain is from bottom to top, the problem of insufficient airflow when the conventional air curtain blows from top to bottom can be effectively solved, the automatic induction start and stop can be realized, and the electricity consumption is relatively saved.
In order to achieve the purpose, the utility model adopts the following technical scheme: the utility model provides an automatic blow-up formula air curtain, is including going out tuber pipe, blast pipe, rat blocking board and outlet duct, the fan that goes out tuber pipe upper end through blast pipe and top be connected its characterized in that: the air-out pipe constitute by the hollow square pipe of two sections L types, the both sides of air-out pipe are fixed on the door frame, the bottom of air-out pipe sinks on ground, is equipped with two vertical blend stops in the both sides of air-out pipe, is equipped with two horizontal blend stops in air-out socle portion, air-out intraductal outlet duct that is equipped with a plurality of wind gap and blows up that is equipped with, block mouse board for controlling two, insert respectively in two vertical blend stops and two horizontal blend stops of air-out pipe, air-out pipe on be equipped with proximity switch, be equipped with proximity switch response piece on the block mouse board.
The air outlet pipe is a hollow round pipe, is uniformly and obliquely inserted and fixed in the air outlet pipe, and has a vertical inclination angle of 10-15 degrees with the ground.
Compared with the prior art, the utility model has the beneficial effects that:
1. an air flow blowing upward from the ground can be formed. Because the bottom of the air outlet pipe is sunk on the ground, and the air outlet pipe with a plurality of air ports blowing upwards is arranged in the air outlet pipe, certain wind power is blown upwards from the ground to form air flow from bottom to top, so that the problem that the air flow is insufficient and the outdoor air cannot be completely isolated when a conventional air curtain is blown downwards from top is effectively avoided.
2. The fan of air curtain can open and stop automatically through proximity switch response, realizes automatic control, the using electricity wisely. According to the utility model, the proximity switch is arranged on the air outlet pipe, the proximity switch induction sheet is arranged on the rat blocking plate, when the rat blocking plate is moved away, the proximity switch induction sheet is separated from the proximity switch, and the fan is immediately started to start working to form air flow from bottom to top; when the rat blocking plate is put back, the proximity switch senses the proximity switch sensing piece, and the fan stops running immediately, so that the effect of saving electricity is achieved.

Detailed Description
The utility model will be further explained with reference to the drawings.
As shown in fig. 1 and 2, the automatic upward blowing type air curtain of the present invention includes an air outlet pipe 1, an air supply pipe 4, a rat guard 7 and an air outlet pipe 9. The upper end of the air outlet pipe 1 is connected with a fan 5 at the top through an air pipe, and the fan 5 is fixed in an interlayer of the door 12. The air outlet pipe 1 consists of two sections of L-shaped hollow square pipes, two sides of the air outlet pipe 1 are fixed on a door frame, the bottom of the air outlet pipe 1 sinks on the ground, and the sinking depth is 4 cm. Two vertical barrier strips 3 are arranged on two sides of the air outlet pipe 1, two horizontal barrier strips 6 are arranged at the bottom of the air outlet pipe 1, and the upper ends of the horizontal barrier strips 6 are flush with the ground slice. The air outlet pipe 1 is internally provided with a plurality of air outlet pipes 9 with air ports blowing upwards, the air outlet pipes 9 are hollow round pipes, the air outlet pipes 9 are uniformly and obliquely inserted and fixed in the air outlet pipe 1, and the vertical inclination angle of the air outlet pipes 9 and the ground is 15 degrees. The mouse blocking plates 7 are divided into a left mouse blocking plate and a right mouse blocking plate, the left mouse blocking plate and the right mouse blocking plate are respectively inserted into the two vertical blocking strips 3 and the two horizontal blocking strips 6 of the air outlet pipe 1, and when the left mouse blocking plate and the right mouse blocking plate 7 are spliced together, the left mouse blocking plate and the right mouse blocking plate are mutually attracted by the magnetite arranged on one side of the mouse blocking plates 7, so that the sealing performance of the mouse blocking plates 7 is improved. The two rat blocking plates 7 can prevent rats from entering a workshop or a warehouse and can play a role in rain prevention. In order to realize automatic control of the fan 5, the air outlet pipe 1 is provided with a proximity switch 2, and the rat guard 7 is provided with a proximity switch induction sheet 8.
The working mode of the utility model is as follows: when someone or goods get into the workshop or raw materials warehouse, open the door after, when removing two blocks of block rat boards 7 on the left and right sides of concatenation together, proximity switch response piece 8 and proximity switch 2 separation, fan 5 just starts work immediately, forms the air current from the bottom up. The amount of airflow is controlled by the power of the fan 5, which is typically 700 watts. When the rat guard 7 is put back, the proximity switch 2 senses the proximity switch sensing piece 8, and the fan 5 stops running immediately, so that the effect of saving electricity is achieved.
As shown in figure 3, the automatic upward blowing type air curtain can be used in cooperation with a conventional strip-shaped air curtain, when a door is opened, the strip-shaped air curtain is started through induction of the magnetic induction switch, the fan works to blow out air flow with the height of more than 1 meter from top to bottom, and at the moment, the rat blocking plate is removed.
