Description
Technical Field
The utility model relates to a communication structure, in particular to an air duct switching structure.
Background
The kitchen in the family life is an indispensable place in our life, and there are various electric appliances, wherein the range hood is a main life electric appliance. However, along with the improvement of living standard, the demands of people on kitchen air conditioners are stronger and stronger, but in traditional decoration, only the exhaust port of a range hood is reserved in an independent flue, and if the kitchen air conditioner is required to be installed in a kitchen, the exhaust port is required to be re-cut on the wall of the flue or a special puncher is required to be added, so that the modification process is complicated, and the cost is increased. Meanwhile, the air conditioner can be used in the top space of a bathroom, and the problem of the same air outlet of various electrical appliances is solved.
Disclosure of Invention
In order to solve the problems, the utility model provides the following scheme:
the utility model provides an air duct switching structure, includes the tee bend main part, and the tee bend main part includes first air exit, second air exit and connector; a switching structure is arranged in the first air outlet, the switching structure comprises a switching air door, a rotating shaft is arranged in the center of the switching air door, two ends of the rotating shaft are rotationally connected with the side wall of the first air outlet, one end of the rotating shaft is connected with a rotating motor, and the rotating motor controls the rotating shaft to rotate so as to control the switching air door to rotate; the connecting port is communicated with a one-way check valve.
Further, the second air outlet is also provided with a switching structure.
Further, the outer wall of the connecting port is provided with a connecting flange for connecting the one-way check valve.
The beneficial effects of the utility model are as follows:
1. the new cutting or the addition of an air outlet by a special puncher is avoided;
2. the on-off of the air outlet is controlled by rotating the motor, so that the oil smoke backflow prevention is more reliable;
3. on the premise of ensuring the rotating force of the rotating motor, the problem that the valve cannot be opened or is opened insufficiently due to the oil smoke adhesion force is effectively prevented.
Drawings
FIG. 1 is a front view of the utility model;
fig. 2 is a side view of the present utility model.
In the figure: 1. a tee body; 2. a first exhaust outlet; 3. a second exhaust outlet; 4. a connection port; 5. switching an air door; 6. rotating the fan; 7. and (5) connecting the flanges.
Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.
Example 1: as shown in figures 1-2 of the drawings,
the utility model provides an air duct switching structure, includes tee bend main part 1, and tee bend main part 1 includes first air exit 2, second air exit 3 and connector 4; a switching structure is arranged in the first air outlet 2, the switching structure comprises a switching air door 5, a rotating shaft is arranged in the center of the switching air door 5, two ends of the rotating shaft are rotationally connected with the side wall of the first air outlet 2, one end of the rotating shaft is connected with a rotating motor 6, and the rotating motor 6 controls the rotating shaft to rotate so as to control the switching air door 5 to rotate; the connecting port 4 is communicated with a one-way check valve.
Further, the second air outlet 3 is also provided with a switching structure.
Further, the outer wall of the connecting port 4 is provided with a connecting flange 7 for connecting a one-way check valve.
The utility model sets a switching structure in the first air outlet 2 or the second air outlet 3 on the three-way main body 1, controls the on-off of the air outlet according to the requirement, and communicates the one-way check valve matched with the original range hood with the connecting port 4. According to actual demand, also can all set up the switch structure in first air exit 2 and second air exit 3, set up through the switch and open and close switch damper 5 at will according to actual demand, reach the effect that the grease proofing cigarette of airing exhaust flows backward.
The utility model avoids new cutting or increases an air outlet by using a special puncher; the on-off of the air outlet is controlled by rotating the motor 6, so that the oil smoke backflow prevention is more reliable; on the premise of ensuring the rotating force of the rotating motor 6, the problem that the valve is not opened or is insufficiently opened due to the oil smoke adhesion force is effectively prevented.
Finally, it should be noted that the above list is only specific embodiments of the present utility model. Obviously, the utility model is not limited to the above embodiments, but many variations are possible. All modifications directly derived or suggested to one skilled in the art from the present disclosure should be considered as being within the scope of the present utility model.
