Description
Technical Field
The utility model belongs to the technical field of ventilation equipment, a tripe formula supply-air outlet structure is related to.
Background
As a terminal of a ventilation system, common air outlets are single-layer movable louver air outlets, double-layer movable louver air outlets, pore plate grid air outlets, air diffusers, contraction nozzles and the like, most air outlets of the ventilation system intermittently output air, taking the louver air outlets as an example, the through-flow section of the air outlets is manually regulated, except for arranging a louver automatic controller, the traditional louvers cannot be automatically closed when the air outlets are idle, the size of the air outlets cannot be regulated according to the size of air flow, and therefore the louvers have the problems of dust accumulation, backflow to the front end of the ventilation system and the like when the louvers are idle, and faults of other devices of the ventilation system and blockage of the air outlets are caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a tripe formula supply-air outlet structure to the above-mentioned problem that prior art exists, the utility model aims to solve the technical problem that how realize the automatic adaptation of blade aperture, especially can close the supply-air outlet when not having the air current to see off.
The purpose of the utility model can be realized by the following technical proposal: a louvered air supply outlet structure is characterized by comprising an installation frame and at least one air guide assembly arranged on the installation frame, wherein the air guide assembly comprises a plurality of blades which are parallel to each other, one side of each blade is rotatably connected with a rotating rod, magnetic attraction is formed between the rotating rod and the blade, and the rotating rod is fixed on the installation frame; one of the two adjacent blades, which is far away from the rotating rod, can attract the rotating rod of the other blade; each blade can seal the frame opening of the mounting frame.
Furthermore, the number of the air guide assemblies is two.
Furthermore, the rotating rod is made of a permanent magnet material, and the blades are made of an iron material.
Furthermore, the rotating rods of the two air guide assemblies are distributed on the mounting frame in a staggered mode.
The frame mouth of installing frame is as the air outlet, the installing frame generally need be vertical to be settled or with vertical between the face be less inclination and settle, make the blade can seal the installing frame mouth completely because of the magnetic force effect between blade and the bull stick when the nature droops, two air guide component then go out at the frame mouth of installing frame and form dual shutoff, when ventilation system is idle, each blade can seal the supply-air outlet, make ventilation system's external environment can not form the interference to the inside of supply-air system, especially vapor, the front end of ventilation system can not got into through the gap between the blade to dust etc., and then cause harmful effects to each part in the ventilation system, make ventilation system inside clean, long service life, the maintenance cycle is long.
Two sets of air guide assemblies arranged in a staggered mode can improve the sealing effect when the ventilation system is idle, and the air flow can be more uniform when being sent out. When the airflow is sent out from one side of the mounting frame to the other side, the airflow acts on one end, far away from the rotating rod, of the blade, so that the blade rotates for a certain angle around the rotating rod, the frame opening of the mounting frame is opened, the greater the airflow strength is, the greater the opening degree is, and the self-adaption advantage is achieved.

Fig. 2 is a schematic structural view when a small air flow passes through the air supply opening.
FIG. 3 is a schematic view of the structure of the air supply opening when a larger air flow passes through the air supply opening.
In the figure, 1, a frame is installed; 2. a blade; 3. a rotating rod.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1, 2 and 3, the structure of the louvered air supply opening includes a mounting frame 1 and at least one air guide assembly arranged on the mounting frame 1, the air guide assembly includes a plurality of blades 2 parallel to each other, one side of each blade 2 is rotatably connected with a rotating rod 3, magnetic attraction is provided between the rotating rod 3 and the blade 2, and the rotating rod 3 is fixed on the mounting frame 1; one of the two adjacent blades 2, which is far away from the rotating rod 3, can attract the rotating rod 3 of the other blade 2; each blade 2 can close the frame opening of the mounting frame 1. The air guide assemblies are two, and rotating rods 3 of the two air guide assemblies are distributed on the mounting frame 1 in a staggered mode.
The rotating rod 3 is made of a permanent magnet material, and the blades 2 are made of an iron material.
The frame mouth of installing frame 1 is as the air outlet, installing frame 1 generally the condition need be vertical to be settled or with vertical between be less inclination and settle, make blade 2 can be because of the magnetic force effect between blade 2 and the bull stick 3 and totally seal installing frame 1 frame mouth when the nature droops, two air guide component then go out at the frame mouth of installing frame 1 and form dual shutoff, when ventilation system is idle, each blade 2 can seal the supply-air outlet, make ventilation system's external environment can not be to the inside interference that forms of air supply system, especially vapor, dust etc. can not get into ventilation system's front end through the gap between blade 2, and then cause harmful effects to each part in the ventilation system, make inside clean of ventilation system, long service life, maintain the cycle length.
Two sets of air guide assemblies arranged in a staggered mode can improve the sealing effect when the ventilation system is idle and enable air flow to be more uniform when the air flow is sent out. When the airflow is sent out from one side of the mounting frame 1 to the other side, the airflow acts on one end, far away from the rotating rod 3, of the blade 2, the blade 2 rotates for a certain angle around the rotating rod 3, and therefore the frame opening of the mounting frame 1 is opened, the larger the airflow strength is, the larger the opening degree is, and the self-adaption advantage is achieved.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
