Description

Technical Field

[0001] This application relates to the technical field of tobacco processing, and in particular to a fan. Background Technology

[0002] Tobacco stems are an important component of tobacco leaves. Unfermented tobacco stems have a rough taste and are highly irritating. Therefore, in order to ensure the quality of cigarettes, tobacco stem fermentation beds are usually used to ferment the tobacco stems. The hot air blower of the tobacco stem fermentation bed can heat the tobacco stems to achieve fermentation.

[0003] During the fermentation process of tobacco stems, the heating position needs to be adjusted to achieve the best fermentation effect. In traditional technology, hot air blowers are usually set up at different locations in the tobacco stem fermentation bed to deliver hot air to different locations in the tobacco stem fermentation bed. The heating position is adjusted by turning these hot air blowers on and off. However, this method increases the manufacturing cost of the tobacco stem fermentation bed. Utility Model Content

[0004] Therefore, it is necessary to provide a fan distribution fan to address the problem that adjusting the heating position of tobacco stems by opening and closing hot air blowers at different locations in traditional technologies increases the manufacturing cost of tobacco stem fermentation beds.

[0006] One embodiment provides a distribution fan, comprising:

[0007] The housing has a communicating air inlet, a first air outlet and a second air outlet, and the air inlet has a first hole wall and a second hole wall disposed opposite to each other along a first direction of the housing;

[0008] A partition mechanism is provided inside the housing. The partition mechanism includes an abutment and a partition member. The abutment is connected to the partition member. The abutment is used to abut between the first air outlet and the second air outlet. The partition member is located at the air inlet and can reciprocate between the first hole wall and the second hole wall.

[0009] In the aforementioned fan, hot air produced by the hot air blower enters the housing through the air inlet. The first and second air outlets are used to connect with different positions on the tobacco stem fermentation bed. A baffle is located at the air inlet, and an abutment connected to the baffle abuts between the first and second air outlets to divert the hot air produced by the hot air blower. By moving the baffle between the first and second hole walls of the air inlet, the flow rate of the hot air flowing out of the first and second air outlets can be adjusted. Compared with traditional technology, the aforementioned fan can direct the hot air produced by the hot air blower to different positions on the tobacco stem fermentation bed through the first and second air outlets, and adjust the flow rate of the hot air flowing to different positions by moving the baffle. It can achieve the adjustment of the heating position of the tobacco stems without the need for multiple hot air blowers, resulting in low implementation cost.

[0035] Please see Figures 1 to 3One embodiment of this application provides a fan, including a housing 100 and a baffle mechanism 200. The housing 100 has a communicating air inlet 110, a first air outlet 120 and a second air outlet 130. The air inlet 110 has a first hole wall 111 and a second hole wall 112 disposed opposite to each other along a first direction of the housing 100. The baffle mechanism 200 is disposed inside the housing 100 and includes an abutment member 210 and a baffle member 220. The abutment member 210 is connected to the baffle member 220 and is used to abut between the first air outlet 120 and the second air outlet 130. The baffle member 220 is located at the air inlet 110 and can reciprocate between the first hole wall 111 and the second hole wall 112.

[0036] The aforementioned air distribution fan, in which hot air produced by the hot air blower enters the housing 100 through the air inlet 110, and the first air outlet 120 and the second air outlet 130 are used to communicate with different positions of the tobacco stem fermentation bed, the partition 220 is located at the air inlet 110, and the abutment 210 connected to the partition 220 abuts between the first air outlet 120 and the second air outlet 130 to distribute the hot air produced by the hot air blower, through the partition 220 at the first hole wall 111 and the second air outlet 130. The movement between the two walls 112 adjusts the flow rate of hot air flowing from the first air outlet 120 and the second air outlet 130. Compared with traditional technology, the above-mentioned fan can direct the hot air produced by the hot air blower to different positions of the tobacco stem fermentation bed through the first air outlet 120 and the second air outlet 130, and adjust the flow rate of the hot air flowing to different positions by moving the baffle 220. The heating position of the tobacco stem can be adjusted without setting up multiple hot air blowers, and the implementation cost is low.

[0037] For explanation, the partition mechanism 200 can move within the housing 100 to allow the partition member 220 to reciprocate between the first hole wall 111 and the second hole wall 112. During this process, the abutment member 210 can abut between the first air outlet 120 and the second air outlet 130 to block the gap between the first air outlet 120 and the second air outlet 130. In this way, when the partition member 220 moves, it can prevent air leakage between the first air outlet 120 and the second air outlet 130, thus ensuring the adjustment effect.

[0038] Optionally, the first air outlet 120 and the second air outlet 130 can be located on the same side of the housing 100, for example, both can be located on the bottom side of the housing 100, or they can be located on different sides of the housing 100 respectively, which will not be elaborated here.

[0039] Furthermore, in this embodiment, the air inlet 110 is used to communicate with the hot air blower, while the first air outlet 120 and the second air outlet 130 are respectively connected to different positions of the tobacco stem fermentation bed to introduce hot air to the tobacco stems located at different positions of the tobacco stem fermentation bed. The adjustment of the hot air flow rate at different positions is achieved by moving the baffle 220, which will not be described in detail here.

[0040] Furthermore, please refer to Figure 5 The first air outlet 120 and the second air outlet 130 can be connected to different locations of the tobacco stem fermentation bed through the ventilation pipe 800.

[0041] Optionally, the baffle mechanism 200 can be a baffle, curtain, or other component that can prevent the flow of hot air; no specific limitation is made here.

[0042] In one embodiment, the first direction is the length direction of the housing 100, that is... Figure 2 In the B direction.

[0043] Please see Figures 1 to 3 In one embodiment, the housing 100 has a first side portion 141, a second side portion 142, and a third side portion 143. The first side portion 141 and the third side portion 143 are disposed opposite each other along a second direction of the housing 100, and the second direction is set at an angle to the first direction. The second side portion 142 is disposed between the first side portion 141 and the third side portion 143. An air inlet 110 is opened on the first side portion 141. The first hole wall 111 is disposed away from the second side portion 142, and the second hole wall 112 is disposed close to the second side portion 142. A first air outlet 120 is disposed on the second side portion 142. The second side portion 142 is provided with an abutting part 150, which is located between the first air outlet 120 and the third side portion 143. An abutting member 210 is used to abut against the abutting part 150. A second air outlet 130 is disposed on the third side portion 143.

[0044] The abutting member 210 abuts against the abutting mating part 150 located between the first air outlet 120 and the third side 143, so as to block the first air outlet 120 and the second air outlet 130 by means of the partition mechanism 200. The first hole wall 111 is disposed away from the second side 142, and the second hole wall 112 is disposed close to the second side 142. Thus, when the partition member 220 moves closer to the first hole wall 111, the flow rate of hot air from the air inlet 110 to the second air outlet 130 decreases, while the flow rate of hot air to the first air outlet 120 increases. Correspondingly, when the partition member 220 moves closer to the second hole wall 112, the flow rate of hot air from the air outlet to the second air outlet 130 increases, while the flow rate of hot air to the first air outlet 120 decreases, so as to adjust the flow rate of hot air flowing to different positions.

[0045] Furthermore, the second direction is the height direction and is set perpendicular to the first direction, that is... Figure 2 In the C direction.

[0046] Furthermore, please refer to Figures 1 to 3 The first side 141 is the top of the housing 100, the third side 143 is the bottom of the housing 100, and the second side 142 is the side connecting the top and bottom of the housing 100, which will not be described in detail here.

[0047] As an explanation, the abutting part 150 is the part of the second side 142 that does not have the second air outlet 130. The abutting part 150 is located below the second air outlet 130 to achieve abutment against the abutting member 210. As an example, the abutting part 150 is the inner wall of the second side 142 near the third side 143.

[0048] Please see Figures 2 to 3 In one embodiment, the partition 220 has a first end 221 and a second end 222 opposite to each other, the abutment 210 has a bent portion 211 and an abutment portion 212, the second end 222 is connected to the bent portion 211, the first end 221 is located at the air inlet 110 and can reciprocate between the first hole wall 111 and the second hole wall 112, so that the partition mechanism 200 can switch between a first position, a second position and a third position;

[0049] Specifically, when the partition mechanism 200 is in the first position, the first end 221 abuts against the first hole wall 111, and the abutting part 212 abuts against the abutting mating part 150; when the partition mechanism 200 is in the second position, the first end 221 is located between the first hole wall 111 and the second hole wall 112, and the bent part 211 abuts against the abutting mating part 150; when the partition mechanism 200 is in the third position, the first end 221 abuts against the second hole wall 112, and the partition member 220 closes the first air outlet 120.

[0050] When the partition mechanism 200 is in the first position, since the first end 221 abuts against the first hole wall 111 and the abutting part 212 abuts against the abutting fitting part 150, all the hot air entering from the air inlet 110 flows to the first air outlet 120 and not to the second air outlet 130; when the partition mechanism 200 is in the second position, the first end 221 is located between the first hole wall 111 and the second hole wall 112, and the bent part 211 abuts against the abutting fitting part 150. 50. Therefore, under the diversion effect of the first end 221, part of the hot air entering from the air inlet 110 flows to the first air outlet 120 and the other part flows to the second air outlet 130. When the baffle mechanism 200 is in the third position, the first end 221 abuts against the second hole wall 112, and the baffle 220 closes the first air outlet 120. Therefore, all the hot air entering from the air inlet 110 flows to the second air outlet 130 and not to the first air outlet 120.

[0051] For explanation, please refer to Figure 3 The solid line represents the first position of the partition mechanism, while the dashed line represents the second and third positions. This will not be elaborated further here.

[0052] The bending portion 211 is provided so that the partition 220 and the abutment portion 212 are set at an angle. Thus, when the partition mechanism 200 is in the second position, the protruding part of the bending portion 211 can abut against the abutment part 150 to block the first air outlet 120 and the second air outlet 130, thereby ensuring the delivery effect of hot air.

[0053] Furthermore, the protruding portion of the bent portion 211 is provided to protrude toward the second side portion 142.

[0054] Furthermore, due to the bending of the bending portion 211, the gap between the baffle mechanism 200 and the mating portion 150 can be kept small at any position, thereby improving the air guiding effect.

[0055] Please see Figure 3 In one embodiment, the first end 221 is provided with a flexible buffer 223 to provide an impact buffer between the first end 221 and the wall of the air inlet 110.

[0056] Please see Figures 1 to 3 In one embodiment, the fan further includes a rotating mechanism 300, which is disposed in the housing 100, and the bent portion 211 is connected to the rotating mechanism 300.

[0057] The rotating mechanism 300 is connected to the bending part 211 to drive the partition mechanism 200 to move, thereby enabling the partition member 220 to reciprocate between the first hole wall 111 and the second hole wall 112 to achieve switching between the first position, the second position and the third position.

[0058] Furthermore, since the bent portion 211 has higher strength, connecting the rotating mechanism 300 to the bent portion 211 can improve the connection strength between the partition mechanism 200 and the rotating mechanism 300.

[0059] Furthermore, the rotating mechanism 300 is located inside the housing 100 to drive the partition mechanism 200 inside the housing 100 to rotate.

[0060] Please see Figures 2 to 4 In one embodiment, the rotating mechanism 300 includes a rotating shaft 310 and a connecting member 320. The rotating shaft 310 is rotatably disposed in the housing 100, the connecting member 320 is connected to the side wall of the rotating shaft 310, and the bent portion 211 is connected to the connecting member 320.

[0061] The rotating shaft 310 can drive the connector 320 and the bending part 211 to rotate, thereby driving the partition mechanism 200 to rotate; the connector 320 is connected to the bending part 211 to improve the overall connection strength between the connector 320 and the partition mechanism 200 and prevent connection failure.

[0062] Furthermore, the axial direction of the rotating shaft 310 is perpendicular to the first direction and the second direction.

[0063] Optionally, one end of the rotating shaft 310 can be rotatably connected to the side wall inside the housing 100, or both ends of the rotating shaft 310 can be rotatably connected to two opposite side walls inside the housing 100, without any specific limitation here.

[0064] Optionally, the rotating shaft 310 can be driven to rotate by electrical drive or by manual rotation; no specific limitation is made here.

[0065] Please see Figures 2 to 4 In one embodiment, the housing 100 has a mounting hole 160, one end of the rotating shaft 310 passes through the mounting hole 160 and is located outside the housing 100, and the fan also includes a control handle 400, which is connected to the end of the rotating shaft 310 located outside the housing 100.

[0066] With this configuration, the operator can rotate the rotating shaft 310 by rotating the control handle 400 outside the housing 100, thereby moving the partition mechanism 200. This allows the partition 220 to move back and forth between the first hole wall 111 and the second hole wall 112, enabling switching between the first position, the second position, and the third position, thus simplifying the operation.

[0067] Further, please refer to Figure 4The fan also includes a seal 500, which is sleeved on the end of the rotating shaft 310 located outside the housing 100 to seal the mounting hole 160, prevent hot air from flowing out of the mounting hole 160, and ensure the hot air delivery effect.

[0068] Furthermore, the rotating shaft 310 passes through the seal 500 and is connected to the control handle 400, and the rotating shaft 310 is able to rotate relative to the seal 500.

[0069] As an example, when the housing 100 has mounting holes 160 on both opposite side walls for the opposite ends of the rotating shaft 310 to pass through, two seals 500 are also provided to seal the two mounting holes 160 respectively.

[0070] Please see Figures 2 to 3 In one embodiment, the bent portion 211 is rotatably connected to the connector 320, and a guide groove 170 is provided in the housing 100. The guide groove 170 extends along a first direction. The fan also includes a guide mechanism 600, which is disposed on the partition 220 and guides and cooperates with the guide groove 170.

[0071] The guide mechanism 600 connected to the partition 220 is guided and engaged with the guide groove 170 inside the housing 100. The guide groove 170 extends along the first direction so that the first end 221 can reciprocate along the first direction. Since the guide groove 170 can play a certain guiding and limiting role for the partition 220, the movement path of the first end 221 can be roughly parallel to the first direction, so that the first end 221 can only move at the air inlet, preventing the first end 221 from protruding from the air inlet of the housing 100 and causing collisions with other parts outside the housing 100.

[0072] Furthermore, the guide groove 170 is formed on the side wall of the housing 100 and extends along the first direction.

[0073] Please see Figure 2 In one embodiment, the guide groove 170 is provided in two parts and is respectively provided on opposite sides of the housing 100 along a third direction. The third direction is perpendicular to the first direction and the second direction. In this way, the two sides of the partition 220 can be guided to ensure the guiding effect.

[0074] Furthermore, the third direction is the width direction of the housing 100, that is... Figure 2 In the direction D, the third direction is parallel to the axis of rotation 310.

[0075] Please see Figures 2 to 4In one embodiment, the guide mechanism 600 includes a guide rod 610 and a guide bearing 620. The guide rod 610 is disposed on the partition 220, and the inner ring surface of the guide bearing 620 is sleeved on the outside of the guide rod 610. The outer ring surface of the guide bearing 620 rolls into contact with the groove wall of the guide groove 170.

[0076] The guide rod 610 is located on the partition 220 and drives the partition 220 to move under the rolling cooperation of the guide bearing 620 and the groove wall of the guide groove 170. The setting of the guide bearing 620 can reduce the friction between the guide rod 610 and the groove wall of the guide groove 170, so as to improve the stability of the partition 220 when moving.

[0077] Furthermore, when there are two guide grooves 170 and they are located on opposite sides of the housing 100 along a third direction, the guide bearings 620 are located at opposite ends of the guide rod 610 and are arranged in a one-to-one correspondence with the two guide grooves 170.

[0078] Please see Figure 4 and Figure 6 In one embodiment, the bottom wall of the guide groove 170 is in communication with the outer side of the housing 100 to facilitate the installation and removal of the guide bearing 620 and the guide rod 610.

[0079] Furthermore, it also includes a removable groove cover 171, which can seal the part where the guide groove 170 communicates with the outside of the housing 100 to prevent hot air leakage.

[0080] Please see Figure 4 In one embodiment, the contact surface between the guide groove 170 and the guide bearing 620 is provided with a wear-resistant strip 172, which improves the wear resistance between the guide bearing 620 and the guide groove 170 and facilitates replacement.

[0081] Please see Figures 2 to 4 In one embodiment, the connector 320 is provided with at least two connectors and is spaced apart along the axial direction of the rotation shaft 310.

[0082] By providing at least two connectors 320 spaced apart along the axial direction of the rotation shaft 310, the connection strength between the rotation shaft 310 and the bent portion 211 can be improved, and the connectors 320 can be prevented from breaking.

[0083] Please see Figure 2 In one embodiment, the connector 320 includes a connecting rod, one end of which is connected to the rotating shaft 310, and the other end of which is rotatably connected to the bent portion 211.

[0084] Furthermore, the bent portion 211 is provided with a reinforcing rib 213, and the end of the connecting rod away from the rotating shaft 310 is rotatably connected to the reinforcing rib 213 to further improve the connection stability.

[0085] Please see Figures 1 to 3 In one embodiment, two second side portions 142 are provided, and the two second side portions 142 are arranged opposite to each other along the first direction of the housing 100. Two air inlets 110, two first air outlets 120, two abutting mating portions 150 and two partition mechanisms 200 are provided and are arranged in one-to-one correspondence with the second side portions 142.

[0086] This setup allows the hot air from the hot air blower to be divided into three streams and further delivered to other parts of the tobacco stem fermentation bed, thus heating more parts of the tobacco stems.

[0087] Please see Figure 3 In one embodiment, the fan further includes a limiting baffle 700. The housing 100 is provided with an air inlet channel, and the limiting baffle 700 is provided in the air inlet channel to divide the air inlet channel into two air inlets 110.

[0088] Furthermore, the limiting baffle 700 serves as the first hole wall 111 of the two air inlets 110 on opposite sides along the first direction. When both baffle mechanisms 200 are in the first position, the first ends 221 of the two baffle mechanisms 200 can respectively abut against the limiting baffle 700 on opposite sides along the first direction to guide hot air into the first air outlet 120 instead of flowing to the second air outlet 130.

[0089] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0090] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
