[0031] Please refer to Figure 1The utility model proposes an air vent structure 1000, which is applied to a smoking device, wherein the smoking device includes an air vent hood, the air vent hood is provided with a smoke inlet, the air vent structure 1000 includes a mounting seat 1, a driving member 2 and a baffle 3, the mounting seat 1 is provided with an air inlet channel 11 and an air inlet 12 and an air outlet 13 connected to the air inlet channel 11, the mounting seat 1 is arranged in the air vent hood, the air inlet 12 is connected to the smoke inlet; the driving member 2 is arranged on the bottom wall of the air inlet channel 11; the baffle 3 is connected to the driving end of the driving member 2, and the driving member 2 is used to drive the baffle 3 to move close to or away from the air inlet 12 to close or open the air inlet 12.

[0032] In the technical solution of the utility model, when smoking is needed, the driving member 2 drives the baffle 3 to move away from the air inlet 12 to open the air inlet 12, and the smoking device produces an adsorption effect on smoke, so that the smoke enters through the smoke inlet and the air inlet 12 and is adsorbed; when smoking is not needed, the driving member 2 drives the baffle 3 to move close to the air inlet 12 to close the air inlet 12; this structural setting can control the opening or closing of the air inlet 12 by controlling the driving member 2, without the need for an operator to always monitor it, thereby reducing the operator's fatigue and improving the smoking efficiency; the driving member 2 can be a cylinder or a motor, and the utility model does not impose any limitation on this.

[0033] To improve the smoke exhaust effect of the exhaust port structure 1000, please refer to Figure 1 In one embodiment of the utility model, a plurality of the air outlets 13 are provided on the side wall or the bottom wall of the air inlet channel 11. After smoke and dust enter from the smoke inlet and the air inlet 12, they can flow out from any of the air outlets 13 in the air inlet channel 11. The plurality of air outlets 13 can increase the chances of smoke and dust being extracted, making the extraction efficiency higher, and avoiding the situation that only one air outlet 13 may not cover the entire working area, resulting in smoke and dust not being completely removed. The provision of a plurality of air outlets 13 can avoid the formation of dead corners in the working area, and each air outlet 13 can cover a certain range of areas, so that the entire working area can be effectively extracted.

[0034] In order to improve the sealing effect of the baffle 3, in one embodiment of the utility model, the baffle 3 is provided with a sealing rubber ring along the circumference of the baffle 3. The sealing rubber ring can effectively seal the air inlet 12 to prevent smoke and dust from leaking out of the air inlet 12, and has the characteristics of good sealing effect and reducing the noise of the smoke extraction device.

[0035] Specifically, in an embodiment of the utility model, the area of ​​the baffle 3 is larger than the area of ​​the air inlet 12. The area of ​​the baffle 3 is larger than the area of ​​the air inlet 12 to improve the sealing effect of the baffle 3, and can also prevent smoke and dust from flowing back into the working area of ​​the cutting machine through the air inlet 12. By increasing the resistance, it can be ensured that only smoke and dust are sucked into the air inlet 12, and there will be no reverse flow phenomenon, ensuring the safety and stability of the operation of the smoke extraction device.

[0036] In order to improve the stability and life of the air vent structure 1000, in one embodiment of the utility model, a buffer seal is provided on the side of the periphery of the air inlet 12 facing the baffle 3. The buffer seal fills the gap between the air inlet 12 and the baffle 3, effectively preventing smoke and dust from entering the working area through the gap, thereby maintaining a clean and safe working environment; due to the elasticity and sealing performance of the buffer seal, smoke and dust can be reduced from leaking out of the air inlet 12, thereby avoiding pollution to the working environment; the driving member 2 will generate vibration and impact when driving the baffle 3 to approach the air inlet 12, and the buffer seal can play a certain buffering role, reducing the impact of vibration and impact on the mounting seat 1, thereby improving the stability and life of the air vent structure 1000.

[0037] More specifically, in an embodiment of the present invention, the baffle plate 3 is provided with a surrounding plate along the circumference of the baffle plate 3, and the surrounding plate is located on the side of the baffle plate 3 facing the air inlet 12. When the baffle plate 3 closes the air inlet 12, the surrounding plate can better isolate the air inlet 12 from the baffle plate 3, thereby improving the sealing effect of the baffle plate 3.

[0038] In order to ensure the moving stroke of the baffle 3, in one embodiment of the utility model, the air vent structure 1000 also includes a sliding block and a slide rail, the baffle 3 is connected to the slide rail, and the slide rail is arranged on the side wall of the air inlet channel 11. The matching design of the slide rail and the slide rail can realize the smooth sliding movement of the baffle 3, reduce friction and vibration, and improve the movement stability of the baffle 3. The design of the slide rail and the slide rail can provide accurate positioning support, ensuring that the baffle 3 can accurately stop at the specified position during the movement, and then the opening of the air inlet 12 can be accurately controlled. Since the slide rail and the slide rail are usually independent parts, they are relatively convenient for maintenance and replacement. If the slide rail or the slide rail fails or wears out, only the corresponding parts need to be replaced, without the need for large-scale repair or replacement of the entire equipment.

[0039] To facilitate installation of the mounting base 1, please refer to Figure 1In one embodiment of the utility model, the mounting base 1 is provided with a connecting plate 14 along the circumference of the air inlet 12. The operator can connect the connecting plate 14 and the exhaust hood by bolts and nuts or screws, and this connection method is used to facilitate the disassembly of the exhaust port structure 1000, and then facilitate the maintenance or replacement of the exhaust port structure 1000.

[0040] Furthermore, in an embodiment of the utility model, the periphery of the baffle 3 is arranged in an arc shape. The arc-shaped periphery can reduce the contact area between the baffle 3 and the smoke, making it easier for the smoke to flow through the baffle 3, reducing the accumulation of smoke on the baffle 3, and the design of the arc-shaped periphery can reduce the resistance of the fluid when it flows through the baffle 3, reduce energy loss, and improve the ventilation effect.

[0041] The utility model also proposes a smoking device, which includes a negative pressure piece, a smoke hood and an exhaust port structure 1000. The specific structure of the exhaust port structure 1000 refers to the above-mentioned embodiment. Since the smoking device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0042] The smoke extraction device includes a negative pressure member, a smoke extraction hood and an air extraction port structure 1000, and the air extraction port structure 1000 includes a mounting seat 1, a driving member 2 and a baffle 3. The mounting seat 1 is provided with an air inlet channel 11 and an air inlet 12 and an air outlet 13 connected to the air inlet channel 11. The mounting seat 1 is arranged in the smoke extraction hood, and the air inlet 12 is connected to the smoke inlet; the driving member 2 is arranged on the bottom wall of the air inlet channel 11; the baffle 3 is connected to the driving end of the driving member 2, and the driving member 2 is used to drive the baffle 3 to move closer to or away from the air inlet 12 to close or open the air inlet 12; the negative pressure member is electrically connected to the driving member 2; the smoke extraction hood is provided with a smoke inlet and a smoke outlet, one end of the smoke extraction hood is connected to the negative pressure member, the smoke outlet is connected to the negative pressure member, and the smoke inlet is connected to the air inlet 12. When the smoking device needs to smoke, the negative pressure member opens and transmits an electrical signal to the driving member 2, and the driving member 2 controls the movement of the baffle 3 to open the air inlet 12. The negative pressure member causes the smoke hood to generate negative pressure, and then the smoke and dust in the external environment enters the air outlet structure 1000 through the smoke inlet and the air inlet 12, and then enters the smoke hood to achieve the adsorption of smoke and dust. The negative pressure member and the driving member 2 can be opened or closed at the same time to ensure normal operation and the safety of the working environment.
