[0033] Reference below Figure 1 and Figure 2 The exhaust structure with light according to the embodiment of the present utility model is described.

[0034] like Figure 1 and Figure 2 As shown, the exhaust structure with lights according to an embodiment of the present invention includes a cylindrical shell 100, a fan 200, a lamp 300 and an electric control room 400.

[0035] The cylindrical shell 100 has an inner cavity, and a lower through hole 101 and an upper through hole 102 are respectively provided at both ends of the cylindrical shell. The lower through hole 101 serves as an air inlet, and the upper through hole 102 serves as an air outlet. The side wall of the cylindrical shell 100 is provided with an external heat dissipation hole 103, and the external heat dissipation hole 103 is located between the lower through hole 101 and the upper through hole 102. The inner cavity of the cylindrical shell 100 is connected to the outside of the cylindrical shell 100 through the external heat dissipation hole 103; the fan 200 is located in the cylindrical shell 100, and is used to drive the air flow in the cylindrical shell 100 to flow from the lower through hole 101 to the upper through hole 102; the lamp 300 is opposite to the lower through hole 101, and the fan 200 is located above the lamp 300, and the lamp 300 and the lower through hole 101 are opposite. A gap is left as an air inlet channel, and air flow can enter the cylindrical shell 100 through the air inlet channel; the electric control room 400 is located in the cylindrical shell 100, and the electric control room 400 is located above the lamp 300, and there is space between the outer wall of the electric control room 400 and the inner wall of the cylindrical shell 100, the electric control room 400 has an inner cavity, and the electric control board 401 is built into the electric control room 400, and the side wall of the electric control room 400 is provided with an inner heat dissipation hole 410, and the inner cavity of the electric control room 400 is connected with the inner cavity of the cylindrical shell 100 through the inner heat dissipation hole 410, and the inner heat dissipation hole 410 is opposite to the outer heat dissipation hole 103, and an air guide plate 420 is also provided on the side wall of the electric control room 400, and the air guide plate 420 is located between the inner heat dissipation hole 410 and the outer heat dissipation hole 103.

[0036] For example, Figure 1 、 Figure 2 and Figure 3 As shown, the cylindrical shell 100, as a cylindrical structure, has an inner cavity. A lower through-hole 101 and an upper through-hole 102 are respectively provided at each end of the cylindrical shell. The lower through-hole 101 serves as an air inlet, and the upper through-hole 102 serves as an air outlet. This means that air can pass through the cylindrical shell 100 from the lower through-hole 101 and be discharged from the upper through-hole 102. External heat dissipation holes 103 are provided on the sidewall of the cylindrical shell 100, allowing air within the cylindrical shell 100 to be discharged through the external heat dissipation holes 103. A fan 200 is located within the cylindrical shell 100 and operates to extract and exhaust air.

[0037] The lamp 300 is located below the lower through hole 101 and serves as a lighting device. A gap is left between the lamp 300 and the lower through hole 101 as an air inlet channel, through which air can enter the cylindrical shell 100, ensuring that the lamp 300 does not block the air flow from entering the cylindrical shell 100.

[0038] The electrical control room 400 is located within the cylindrical shell 100. The electrical control room 400 has an inner cavity and houses an electrical control board 401, which serves as the power control board for the fan 200 and the lamp 300. Internal heat dissipation holes 410 are defined in the sidewalls of the electrical control room 400, connecting the inner cavity of the electrical control room 400 with the inner cavity of the cylindrical shell 100. An air deflector 420 is also provided on the sidewalls of the electrical control room 400, located between the internal heat dissipation holes 410 and the external heat dissipation holes 103.

[0039] In actual operation, the utility model exhaust structure with light is installed at a predetermined position indoors, such as a ceiling or a wall. When the utility model exhaust structure with light is powered on, the fan 200 starts to exhaust air indoors, and the lamp 300 starts to illuminate.

[0040] Reference Figure 8 Assuming that the electric control room 400 is located below the fan 200, after the fan 200 is started, the air flow in the room passes through the air inlet channel formed between the lamp 300 and the lower through hole 101 and enters the cylindrical shell 100. Part of the air flow entering the cylindrical shell 100 is discharged from the upper through hole 102, completing the exhaust work. The other part of the air flow enters and exits the electric control room 400 through the internal heat dissipation holes 410, so that the electric control board 401 in the electric control room 400 can be cooled, ensuring the stability of the operation of the fan 200 and the lamp 300. Air flow also enters the cylindrical shell 100 through the external heat dissipation holes 103 and enters / flows out of the electric control room 400 along the air guide plate 420, thereby increasing the air volume of the air flow entering / flowing out of the electric control room 400.

[0041] Reference Figure 9 Assuming that the electric control room 400 is located on the upper side of the fan 200, after the fan 200 is started, the air flow in the room passes through the air inlet channel formed between the lamp 300 and the lower through hole 101 and enters the cylindrical shell 100. Part of the air flow entering the cylindrical shell 100 is discharged from the upper through hole 102 to complete the exhaust work. Another part of the air flow enters and exits the electric control room 400 through the internal heat dissipation holes 410, so that the electric control board 401 in the electric control room 400 can be cooled, ensuring the stability of the operation of the fan 200 and the lamp 300. Another part of the air flow flows out of the cylindrical shell 100 through the external heat dissipation holes 103. This part of the air flow can cooperate with the air guide plate 420 to increase the air volume of the part of the air flow entering / flowing out of the electric control room 400.

[0042] The design of the air guide plate 420 being located between the inner heat dissipation hole 410 and the outer heat dissipation hole 103 can not only buffer the airflow passing through the space between the inner heat dissipation hole 410 and the outer heat dissipation hole 103, but also guide the airflow in the electric control room 400 to be more easily discharged from the outer heat dissipation hole 103 or at least discharged into the inner cavity of the cylindrical shell 100, which is equivalent to increasing the flow rate of the airflow in and out of the cylindrical shell 100, thereby ensuring the heat dissipation efficiency of the electric control board 401.

[0043] It can be imagined that since the flow rate of the airflow discharged from the upper through hole 102 is related to the area of the upper through hole 102, the flow rate of the airflow in and out of the control room 400 is related to the area of the inner heat dissipation hole 410, and the flow rate of the airflow discharged from the outer heat dissipation hole 103 is related to the area of the outer heat dissipation hole 103, the area sizes of the upper through hole 102, the inner heat dissipation hole 410, and the outer heat dissipation hole 103 can be designed as needed.

[0044] In some embodiments of the present invention, referring to Figure 2 、 Figure 4 The air guide plate 420 is tightly connected to the lower side of the inner heat dissipation holes 410, and the space above the air guide plate 420 serves as an air guide channel, communicating with the inner heat dissipation holes 410 and the outer heat dissipation holes 103. This effectively uses the lower side of the air guide plate 420 to partially block the airflow that passes upward through the space between the inner heat dissipation holes 410 and the outer heat dissipation holes 103, thus buffering this airflow. Furthermore, because the space above the air guide plate 420 serves as an air guide channel, communicating with the inner heat dissipation holes 410 and the outer heat dissipation holes 103, the airflow discharged from the inner heat dissipation holes 410 can more easily exit the cylindrical housing 100 through the outer heat dissipation holes 103, significantly accelerating the airflow in and out of the electric control room 400 and further improving the heat dissipation efficiency of the electric control board 401.

[0045] In some specific embodiments of the present invention, the inner heat dissipation holes 410 and the outer heat dissipation holes 103 are circular through holes, and the air guide plate 420 is an arc-shaped plate with the concave surface facing upward and the convex surface facing downward.

[0046] In some embodiments of the present invention, referring to Figure 3 、 Figure 4 A lower cover 430 is provided on the lower side of the electric control room 400, and the electric control board 401 is connected to the upper side of the lower cover 430. That is, after the electric control board 401 is connected to the lower cover 430, the lower cover 430 can be closed on the lower side of the electric control room 400 to complete the installation of the electric control board 401, making the disassembly and assembly of the electric control board 401 more convenient and flexible.

[0047] In a further embodiment of the present invention, a lower cover buckle 431 is provided at the edge of the lower cover 430, and a lower cover slot 480 is opened on the lower side of the control room 400. The lower cover 430 is clamped in the lower cover slot 480 through the lower cover buckle 431, so that the lower cover 430 can be covered on the lower side of the control room 400.

[0048] In a further embodiment of the present invention, a lower cover plate wire hole 432 is provided on the lower cover plate 430 , so that the wiring of the electric control board 401 can pass through the lower cover plate wire hole 432 to be electrically connected to the lamp 300 .

The first card slot 440 and the second card slot 451 can clamp the upper and lower sides of the circuit board, so that in addition to installing the electric control board 401 in the electric control room 400, other circuit boards or electrical components can be installed as needed.

[0050] In a further embodiment of the present invention, a fastener connecting column 470 is provided on the upper inner wall of the electric control room 400 , and the fastener connecting column 470 is connected to the fastener 450 by screws.

[0051] In some embodiments of the present invention, referring to Figure 2 、 Figure 6 A dust stopper 500 is provided on the upper through hole 102, through which the airflow within the cylindrical housing 100 can be discharged. The dust stopper 500 partially isolates dust from the air discharged through the upper through hole 102. Furthermore, the dust stopper 500 prevents foreign matter from entering the cylindrical housing 100 directly through the upper through hole 102 and affecting the normal operation of the exhaust structure with light.

[0052] In some embodiments of the present invention, referring to Figure 6 A dust stop bracket 510 is provided on the upper through-hole 102. The dust stop bracket 510 has a bracket through-hole 511, and the dust stop 500 is connected to the dust stop bracket 510. The bracket through-hole 511 of the dust stop bracket 510 ensures that the dust stop bracket 510 does not block airflow. The dust stop bracket 510 serves as a fixing and supporting structure for the dust stop 500, ensuring that the dust stop 500 is securely mounted on the upper through-hole 102.

[0053] In a further embodiment of the present invention, the dust-stopping piece 500 is a filter structure.

[0054] In a further embodiment of the present invention, the dust-stopping plate 500 is a filter structure.

[0055] In a further embodiment of the present invention, a dust-stopping plate air hole 501 is provided on the dust-stopping plate 500 to ensure that airflow can smoothly pass through the dust-stopping plate 500 .

[0057] In some specific embodiments of the present invention, a ash stop bracket plug-in portion 512 is provided on the ash stop bracket 510, and a pressure strip plug-in port 521 is provided on the pressure strip 520. The ash stop bracket plug-in portion 512 can be plugged into the pressure strip plug-in port 521 to achieve fixation between the ash stop bracket 510 and the pressure strip 520.

[0058] In a further embodiment of the present utility model, an ash stop bracket buckle 513 is provided at the edge of the ash stop bracket 510, and an upper clamping hole 140 is provided on the cylindrical shell 100. The ash stop bracket buckle 513 of the ash stop bracket 510 can clamp the upper clamping hole 140, so that the ash stop bracket 510 can cover the upper through hole 102.

[0059] In some embodiments of the present invention, referring to Figure 3 The fan 200 includes a motor 210 and blades 220. The motor 210 is used to drive the blades 220 to rotate. A motor bracket 110 is provided within the cylindrical shell 100. The motor 210 is connected to the motor bracket 110 to ensure that the fan 200 is fixedly installed within the cylindrical shell 100.

The inner wall of the cylindrical shell 100 and the motor bracket 110 are connected by a connecting plate 120 to ensure that the fan 200 is sufficiently stable and reliable within the cylindrical shell 100.

[0062] In a further embodiment of the present invention, an upper protrusion 460 is provided on the upper side of the control room 400, and a motor support lower recess 113 is provided in the motor support lower recess 112. The upper protrusion 460 can mate with the motor support lower recess 112, ensuring a secure installation of the control room 400. Both the upper protrusion 460 and the motor support lower recess 113 have through-holes, allowing the wiring of the electric control board 401 to pass through the upper protrusion 460 and the motor support lower recess 112 to electrically connect to the fan 200.

[0063] In some embodiments of the present invention, referring to Figure 2 、 Figure 5 The connecting plate 120 has an air guide slope 121, which is inclined toward the upper side in a clockwise or counterclockwise direction around the motor bracket 110. The air guide slope 121 can guide the airflow in the ventilation channel to form a vortex around the fan 200, thereby avoiding the formation of turbulence in the cylindrical shell 100 and reducing the exhaust efficiency.

[0064] In a further embodiment of the present invention, a plurality of connecting plates 120 surround the motor bracket 110. The connecting plates 120 are inclined plate structures that are inclined upward in a clockwise or counterclockwise direction around the motor bracket 110.
