Alternatively, the housing 10 may have a hexahedral structure, thereby enclosing the accommodating chamber. The housing 10 is provided with a first air port 101 and a second air port 102 on opposite sides thereof, respectively, so that the accommodating chamber communicates with the external environment through the first air port 101 and the second air port 102. It is understood that the first air port 101 may be an air inlet or an air outlet, and the second air port 102 may be an air outlet or an air inlet.

Alternatively, the housing 10 may include a first direction X, a second direction Y, and a third direction Z, which are perpendicular to each other. The first tuyere 101 and the second tuyere 102 are disposed opposite to each other in the first direction X. It should be noted that the first direction X, the second direction Y, and the third direction Z of the housing 10 may be used to describe the structure of other parts hereinafter, so that the first direction X, the second direction Y, and the third direction Z hereinafter may refer to the housing 10 direction.

Alternatively, the outer periphery of the housing 10 has a mounting portion of a protruding surface provided at the outer periphery surrounding the first tuyere 101. Screw holes are formed in the mounting portion for detachably connecting the ventilating device 100 to other equipment.

Alternatively, the blower 20 is fixedly installed in the housing 10, and when the blower 20 is operated, external air flows into the accommodating chamber from the first air port 101 (or the second air port 102) and passes through the first face 201 (or the second face 202), and then flows out of the ventilation device 100 from the second air port 102 (or the first air port 101) after passing through the second face 202 (or the first face 201). Preferably, the first face 201 and the first tuyere 101 are spaced apart, and the second face 202 and the second tuyere 102 are spaced apart. It will be appreciated that the first face 201 may be an air inlet face or an air outlet face, and the second face 202 may be an air outlet face or an air inlet face.

Optionally, the motor 30 is fixedly mounted within the housing 10. It should be explained that the motor 30 and the fan 20 are two independent components, and the fan 20 is internally provided with a driven electric driving structure, and after the fan 20 is powered on, the driven electric driving structure drives the blades of the fan 20 to rotate. While the motor 30 is not responsible for driving the blower 20.

Alternatively, the rotating shaft 40 may be an extension shaft of an output shaft of the motor 30, and the rotating shaft 40 may be fixedly connected or detachably connected with the output shaft of the motor 30, so that the motor 30 may directly drive the rotating shaft 40 to rotate. The axis of the output shaft of the motor 30 may extend in the second direction Y, so the rotating shaft 40 may also extend in the second direction Y.

Alternatively, the wind deflector 50 is directly connected to the outer peripheral surface of the rotating shaft 40, so that the wind deflector 50 can be driven to rotate around the axis of the rotating shaft 40 when the rotating shaft 40 rotates. The wind deflector 50 is disposed at the first wind gap 101, so that rotation of the wind deflector 50 can close or conduct the first wind gap 101.

It is understood that the ventilation device 100 may include a choke state and a ventilation state. In the choke state, the wind deflector 50 is rotated to a position closing the first air port 101, so that external air cannot enter the accommodating chamber through the first air port 101 even when the blower 20 is operated. In the ventilation state, the wind deflector 50 is rotated to a position where the first wind gap 101 is closed, so that the outside air can freely circulate when the blower 20 is operated.

Further, the ventilation device 100 further includes a bracket 60, the bracket 60 is fixedly installed in the housing 10, and the bracket 60 includes a partition plate 610 and a mounting plate 620.

Alternatively, the partition plate 610 may partition the accommodating chamber into two spaces, a ventilation chamber and an accommodating chamber, respectively. Wherein, the pivot 40 of fan 20 installs in ventilation chamber, and motor 30 installs in the chamber of acceping, and the output shaft of motor 30 passes division board 610 and is connected with pivot 40. By providing the partition plate 610 to divide the accommodating chamber into two spaces, it is advantageous to reduce interference between the motor 30 and the fan 20. It will be appreciated that due to the self-contained electrically driven structure of the blower 20 (which may be understood as the other motor 30), the motor 30 and blower 20 are separated in order to ensure stability of the device during operation.

Preferably, the end of the rotating shaft 40 remote from the partition plate 610 is rotatably connected to the housing 10. Thereby enabling both ends of the rotation shaft 40 to be supported, thereby ensuring smoothness of the wind deflector 50 when it rotates.

Alternatively, the mounting plate 620 is connected to the divider plate 610, and preferably at a 90 ° angle, i.e., the plate surface of the mounting plate 620 is parallel to the second surface 202. The mounting plate 620 is located between the blower 20 and the second tuyere 102, and the blower 20 is fixed to the mounting plate 620 by screws. The mounting plate 620 is also provided with an opening so that the opening communicates with the second tuyere 102. By providing the mounting plate 620 for fixing the blower 20 on the one hand and improving the connection strength between the bracket 60 and the housing 10 on the other hand.

According to the utility model, the wind shield 50 is arranged at the first wind gap 101, so that the wind shield 50 is opened and closed or communicated with the first wind gap 101, and external pollutants can be blocked by using the wind shield 50 on the premise of meeting the ventilation function; when the ventilation device 100 is stopped, the wind guard 50 is closed to prevent foreign contaminants from entering the housing 10 to damage the blower 20.

Further, the wind deflector 50 is directly driven by the single motor 30, so that the wind deflector 50 and the fan 20 can be started independently, and the opening speed of the wind deflector 50 can be improved, and compared with the existing multi-stage transmission mode, the ventilation device 100 has high transmission efficiency and the opening speed of the wind deflector 50 is faster; meanwhile, the independent fans 20 and motors 30 are also beneficial to separate control and further beneficial to stepless adjustment modes of the fans 20 and motors 30, so that the ventilation device 100 can have higher automation degree and intelligent degree.

In one embodiment, referring to fig. 3 to 5, the rotating shaft 40 includes a mounting plane 40A, the wind deflector 50 includes a main body plate 510 and a connection plate 520 connected to each other, and the connection plate 520 is connected to the mounting plane 40A; the body plate 510 protrudes from the connecting plate 520 with respect to the first face 201.

Alternatively, the rotating shaft 40 may include a shaft post 401 and a sleeve post 402, wherein the shaft post 401 is directly connected with the output shaft of the motor 30, and the sleeve post 402 is sleeved on the outer circumference of the shaft post 401. Preferably, the axle post 401 and the sleeve post 402 are integrally formed. The sleeve 402 may be quadrilateral in cross-section so that it includes a mounting plane 40A facing the periphery. The connection plate 520 is connected to the mounting plane 40A.

The rotating shaft 40 is arranged into the shaft column 401 and the sleeve column 402, so that on one hand, the shaft column 401 is connected with an output shaft of the motor 30; on the other hand, the outer surface of the post 402 may have more designs, including the flat surfaces of the present application. In other embodiments, the outer surface of the post 402 may also be curved, and thus may be adapted to the web 520 in a curved configuration.

Alternatively, the body plate 510 and the connection plate 520 are each of a flat plate-like structure. The connection plate 520 may be connected to the mounting plane 40A. As the post 402 rotates, the post 402 may rotate the wind deflector 50.

Alternatively, the body plate 510 protrudes from the connecting plate 520 with respect to the first face 201. It will be appreciated that the body plate 510 may be disposed at the first tuyere 101 with the rotary shaft 40 located in the receiving chamber at a spaced distance from the first tuyere 101. Therefore, after one end of the connection plate 520 is connected to the rotation shaft 40, it is at least partially extended to the position of the first tuyere 101, thereby being connected to the body plate 510.

By arranging the rotating shaft 40 with the installation plane 40A, the installation plane 40A can be fixedly connected with the connecting plate 520, and the firmness of connection can be improved by the larger connection area.

The advantage of having the body plate 510 protruding from the connection plate 520 is that it is more advantageous to achieve a direct drive configuration and reserves a space that can be designed. This is because the body plate 510 is located at the first tuyere 101 (for closing the first tuyere 101), and the motor 30 and the rotation shaft 40 are both located in the housing 10. Therefore, compared to the position of the first tuyere 101, the motor 30 and the rotating shaft 40 are both located behind the main body plate 510, and if the main body 511 does not protrude, the main body plate 510 must be too close to the blower 20 for realizing the transmission therebetween. But too close a structure, not only the wind guard 50 is easy to strike the fan 20 in the opening and closing process, but also the later transformation is not facilitated.

In one embodiment, the connection plate 520 and the body plate 510 are an integrally formed structure. It will be appreciated that the wind deflector 50 may be a structure formed by cutting and stamping a complete sheet metal. Or cast by 3D printing and grinding tool. The integral forming structure enables the firmness of the wind deflector 50 to be better, and the kinetic energy loss is lower and the transmission efficiency is higher under the condition that the wind deflector 50 and the rotating shaft 40 are directly driven.

In an embodiment, referring to fig. 5 and 6, the main body plate 510 includes a main body portion 511, a first bending portion 512 and a second bending portion 513, the main body portion 511 is connected to the connecting portion, the first bending portion 512 and the second bending portion 513 are respectively connected to two opposite ends of the main body portion 511, the first bending portion 512 and the second bending portion 513 are all connected to the main body portion 511 in an included angle, and the first bending portion 512 and the second bending portion 513 extend towards a direction close to the fan 20.

Alternatively, the main body 511 is in a flat plate shape, and is mainly used for closing or conducting the first tuyere 101. Preferably, the plate surface of the main body 511 is parallel to the first surface 201, and the plate surface of the main body 511 is perpendicular to the partition plate 610. The body 511 is spaced from the first face 201.

Alternatively, the first bending portion 512 and the second bending portion 513 are connected to opposite ends of the main body portion 511 in the second direction Y. It is understood that the main body 511 may be in a quadrilateral plate shape, and the connection plate 520 is connected to one side thereof, and the first bending portion 512 and the second bending portion 513 are respectively connected to the other two sides.

Optionally, the first bending portion 512 and the second bending portion 513 are both connected to the main body portion 511 at an included angle, and the first bending portion 512 and the second bending portion 513 extend toward a direction close to the fan 20. Preferably, the angle may be 90 °. Therefore, the first and second bending parts 512 and 513 may be parallel to the separation plate 610.

An advantage of providing the first and second bending parts 512 and 513 is that a flow guide can be achieved for the liquid to prevent the liquid from entering the receiving chamber. It will be appreciated that when the device is placed outdoors or in an environment of relatively high humidity, water droplets on the body portion 511 may drip down the first and second bending portions 512, 513 without entering the housing 10.

In one embodiment, referring to fig. 5 and 6, the connection plate 520 includes a first connection portion 521 and a second connection portion 522, the first connection portion 521 is connected to the rotating shaft 40, opposite ends of the second connection portion 522 are respectively connected to the first connection portion 521 and the main body plate 510, the first connection portion 521 is plate-shaped, and the first connection portion 521 is located between the main body plate 510 and the first surface 201.

Alternatively, a surface of the first connection portion 521 facing away from the first tuyere 101 is connected to the mounting plane 40A. Preferably, the plane of the first connecting portion 521 is parallel to the first surface 201, i.e. the first connecting portion 521 is parallel to the main body 511.

Alternatively, the first connection portion 521 and the main body portion 511 have a separation distance therebetween in the first direction X. Therefore, the first connection portion 521 and the main body portion 511 are connected by the second connection portion 522. It will be appreciated that the orthographic projection of the body plate 510, the first connection 521 and the second connection may close the first opening.

By providing the wind deflector 50 in a multi-stage connection structure (the main body plate 510, the first connection portion 521 and the second connection portion 522), the shape of the housing 10 is adapted, so that the wind deflector 50 does not interfere with the housing 10 when the rotation shaft 40 drives the wind deflector 50 to rotate.

In one embodiment, referring to fig. 5 and 6, the second connecting portion 522 is plate-shaped, and the second connecting portion 522 has an included angle with the first connecting portion 521.

Alternatively, the first connecting portion 521, the second connecting portion 522, the main body portion 511, the first bending portion 512, and the second bending portion 513 may be formed by stamping a sheet of metal.

Alternatively, the first connection portion 521 and the main body portion 511 have a separation distance therebetween in the third direction Z. Therefore, the second connecting portion 522 may have an inclined shape.

By providing the second connection portion 522 with an angle with the first connection portion 521, the connection plate 520 may take on an eave structure, thereby further preventing liquid from entering the housing 10. On the one hand, the first connecting portion 521 can block the liquid flowing onto the rotating shaft 40 to erode the motor 30, and on the other hand, the liquid on the first connecting portion 521 can flow out through the second connecting portion 522 with an included angle, so that the liquid is prevented from accumulating at the position.

In one embodiment, referring to fig. 5 and 6, the ventilation device 100 further includes a first plate 630, where the first plate 630 includes a first segment 631 and a second segment 632 connected at an included angle, the first segment 631 and the second segment 632 are both plate-shaped, and, with respect to the first surface 201, the first connection portion 521 protrudes from the first segment 631, and the second segment 632 extends toward the main body plate 510.

Specifically, the bracket 60 described above includes a first plate 630. Wherein the first plate 630 includes a first section 631, a second section 632, and a third section 633 connected in sequence.

Optionally, the first segment 631 and the second segment 632 are each flat, and the third segment 633 is annular. Preferably, first section 631 is parallel to first face 201. The first section 631 is also parallel to the first connection 521 when the wind deflector 50 closes the first wind gap 101. When the wind deflector 50 closes the first air port 101, the rotation shaft 40 is located between the first section 631 and the first connecting portion 521. The first connecting portion 521 protrudes from the first section 631 with respect to the first face 201.

Optionally, the first section 631 is spaced from the shaft 40. The distance is to prevent interference with the first segment 631 when the first connecting portion 521 is rotated.

Alternatively, when the wind deflector 50 closes the first wind gap 101, the third segment 633 is located between the first face 201 and the main body panel 510, and since the third segment 633 is annular, the third segment 633 does not affect the intake air.

Optionally, first section 631 is located rearward of first face 201 and first section 631 and third section 633 have a spacing in third direction Z. Therefore, the second segment 632 forms an angle when connecting the first segment 631 and the third segment 633 (i.e., the second segment 632 forms an angle with the first face 201).

Optionally, the second connecting portion 522 (when closed) forms a first angle with the first surface 201. The second section 632 forms a second angle with the first face 201. The first included angle is smaller than the second included angle.

By providing the first plate 630, it can be used to further block contaminants from passing through the location of the connection plate 520; and the first section 631 and the second section 632 of the first plate 630 have an included angle, which not only can match the included angle formed by the first connection portion 521 and the second connection portion 522, but also can form a secondary eave structure to prevent moisture from invading the fan 20.

In one embodiment, the wind deflector 50 and the shaft 40 are detachably connected. The wind guard 50 and the rotating shaft 40 can be connected by a buckle, a nail hole, magnetism or the like.

In one embodiment, referring to fig. 2, the ventilation device 100 further includes a filter 70, where the filter 70 is installed in the housing 10, and the filter 70 is disposed on a side of the second surface 202 opposite to the first surface 201.

Optionally, the filter screen 70 is located between the second face 202 and the mounting plate 620, the area of the filter screen 70 is larger than the area of the opening on the middle mounting plate 620, and a space is provided between the filter screen 70 and the mounting plate 620.

Alternatively, the fan 20 and the mounting plate 620 are connected by four connecting posts (screws), and two opposite ends of the connecting posts are respectively connected with the fan 20 and the mounting plate 620. And, four connecting posts all wear to locate filter screen 70.

By arranging the filter screen 70, particles or garbage from the outside can be filtered, so that the fan 20 is prevented from being damaged by large-scale impurities; and the conducted air may be filtered.

In one embodiment, the ventilation device 100 further includes an over-controller (not shown in the figure), which is electrically connected to the fan 20 and the motor 30, respectively, and the controller is used for controlling the fan 20 to start or stop, or controlling the motor 30 to rotate so as to drive the wind guard 50 to open or close.

Alternatively, the controller is installed in the above-mentioned middle receiving chamber, and may be fixedly installed on the partition plate 610. The controller is electrically connected to the blower 20 and the motor 30, respectively. The controller may be used to connect to an external control device (e.g., computer, cell phone, IPDA, etc.) whereby the control device may control the blower 20 or the wind deflector 50 by transmitting instructions to the controller.

Optionally, the ventilation device 100 further comprises a sensor. The sensor may be, but is not limited to, a temperature sensor, an air pressure sensor, a smoke sensor, a humidity sensor, etc. The sensor may be electrically connected to the controller such that after the sensor detects a change in the external environment, the controller may control the blower 20 and the motor 30 according to the change.

For example, the sensor is a smoke sensor. When the sensor detects that smoke is generated from the outside, the controller may control the motor 30 to rotate so that the wind guard 50 is opened, and the blower 20 is started, thereby discharging the smoke.

In one embodiment, the controller controls the motor 30 to rotate so that the wind deflector 50 has a plurality of different opening and closing angles, the opening and closing angles being angles formed by the wind deflector 50 and the first surface 201, and the opening and closing angles being 0 ° to 90 °.

Specifically, the controller may control the rotation of the wind deflector 50 to different angles according to the environmental change. It should be noted that when the opening/closing angle is 0 °, the wind deflector 50 (particularly, the main body 511) is parallel to the first surface 201. Therefore, 0 ° is the state where the wind deflector 50 is closed. Conversely, when the opening and closing angle is greater than 0 °, the wind deflector 50 is in an open state.

Optionally, the motor 30 drives the wind deflector 50 to be in a stepless hovering state, that is, the specific opening and closing angle of the wind deflector 50 can be controlled by controlling the rotating angle of the rotating shaft 40.
