Detailed Description
The present invention will be further explained with reference to the drawings attached to the specification.
As shown in fig. 1-3, the suction electrical appliance for opening the air inlet by negative pressure is a ventilation fan, which has a horizontal face shield 100 and a fan 200 located above the face shield, and the horizontal face shield usually makes the whole product installed on the ceiling of the room. The mask 100 is provided with an air inlet 101 for the fan to suck air, the air inlet 101 is covered by the lifting plate 300, so that the lifting plate is lifted from the air inlet by negative pressure formed when the fan sucks air to open the air inlet, and the lifting plate is reset by gravity when the negative pressure disappears. Accordingly, when the product stops working, the air inlet is covered by the lifting plate as shown in fig. 2, so that the internal structure of the product is shielded, parts inside the product cannot be seen through the air inlet, and the appearance of the product is neat. When the product works, the fan sucks air to form negative pressure, the air pressure on the lower side of the lifting plate is larger than the air pressure on the upper side of the lifting plate, the lifting force generated by the air pressure difference lifts the lifting plate from the air inlet to open the air inlet, and the lifting plate resets by virtue of gravity when the negative pressure disappears (such as when the machine is stopped). The lifter plate is preferably a plate material that is light in weight and has a certain rigidity.
In order to properly arrange the lifting plate and the product to form an airflow channel during operation, the blower 200 has an air inlet 201, a positioning column 202 is disposed between the periphery of the air inlet and the edge of the lifting plate, the positioning column keeps a height difference between the lifting plate and the air inlet when the lifting plate is lifted to form an airflow channel for airflow, and the airflow path is marked by an arrow in fig. 3. The positioning posts 202 are shown fixed to the wind-collecting plate 206 around the wind-suction openings, and in particular are also fixed to the upper edge of the lifter plate.
As shown in the figure, the fan 200 includes a box 203, a centrifugal wind wheel 205 driven by a motor 204 and an air collecting plate 206 arranged in the box, wherein the air suction opening 201 is arranged on the air collecting plate 206 and is opposite to the lower end of the centrifugal wind wheel 205; a space for the lifting plate to be lifted is maintained between the wind-collecting plate 206 and the face mask 100.
In order to ensure that enough negative pressure is formed at the air inlet on the mask to lift the lifting plate, the mask is in sealing fit with the box body. The air leakage of the part of the face mask outside the air inlet is avoided.
The circumference of the air inlet 101 is provided with a circumference limiting column 102 to limit the position of the lifting plate so as to ensure that the lifting plate can cover the air inlet when being reset by gravity after being lifted, and the lifting plate can be kept between the circumference limiting columns without being deviated to the circumference after being lifted, so that the stability of air flow when the fan sucks air is ensured.
To add visual effects, the mask 100 is fitted with an atmosphere light 103 along the edge of the air intake. The lifting plate 300 forms a light reflecting surface 301 of the atmosphere lamp. Therefore, the atmosphere lamp can be started in working and non-working processes, and even if the lifting plate is lifted due to the atmosphere lamp and the reflecting surface, the light forms a sight barrier when the atmosphere lamp is started, and internal components of the product cannot be seen. Specifically, the middle portion of the elevating plate 300 protrudes downward to form a lower surface 302, the edge portion of the elevating plate is recessed upward to form an upper surface 303, and the light reflecting surface 301 is formed at the transition portion between the lower surface 302 and the upper surface 303. With the structure, the lifting plate and the face mask can form a better visual design.
For simple structure, the mask 100 has a support edge 104 at the edge of the air inlet, the atmosphere lamp 103 is a strip lamp strip mounted on the upper side of the support edge, and the edge of the lifting plate 300 is placed on the atmosphere lamp 103.
To facilitate assembly, the mask 100 is configured separately from the blower 200. When the fan is installed, the fan (the main unit of the ventilator) is installed on the upper side of the keel by the aid of the installation piece 209, and then the mask 100 is buckled on the keel 400 or connected to the fan through a connecting piece.
When the ventilation fan is not in operation, as shown in fig. 2, the air inlet 101 is covered by the lifting plate 300, so that the internal structure of the product is shielded, and the components inside the product cannot be seen through the air inlet, so that the appearance of the product is neat. When the product works, as shown in fig. 3, the fan sucks air from the air inlet 101 and forms negative pressure on the upper side of the air inlet, the air pressure on the lower side of the lifting plate is greater than the air pressure on the upper side of the lifting plate, the lifting force generated by the air pressure difference lifts the lifting plate from the air inlet to open the air inlet, and the flowing air flow is discharged through the air outlet 207. When the negative pressure disappears (such as during shutdown), the lifting plate is reset to the state shown in fig. 2 by gravity.
In view of the above structure of the ventilator, the technical solution of the present invention can be implemented on other products with ventilation function, such as bathroom warmer.
