Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, and specifically relates to a storage structure. Background Art

[0002] Many families store the bought rice in a rice bucket. When taking rice, they open the lid of the rice bucket and scoop out the rice with a container. The rice bucket is in communication with the external air. The rice in the rice bucket is in contact with the air for a long time, which is prone to insect infestation and damp and mildew. Eating moldy rice will seriously endanger human health. Content of the Utility Model

[0003] In view of this, the utility model provides a storage structure to solve the problem that the rice in the rice bucket is in contact with the air for a long time.

[0004] The utility model provides a storage structure, including:

[0005] A main body for storing materials;

[0006] An air extraction device having an air extraction chamber and an air extraction component disposed in the air extraction chamber. The air extraction chamber is in communication with the interior of the main body through an air inlet hole, and the air extraction chamber is in communication with the exterior of the main body through an exhaust hole;

[0007] A sealing plug is provided at the air inlet hole. When the air extraction component is driven to rotate so that the air pressure in the air extraction chamber is less than the air pressure inside the main body, the sealing plug moves towards the top of the air extraction chamber under the pressure inside the main body to open the air inlet hole, and then the gas inside the main body is sucked into the air extraction chamber and discharged through the exhaust hole.

[0008] Beneficial effects: After the materials are placed inside the main body, the air extraction component is driven to rotate so that the air pressure in the air extraction chamber is less than the air pressure inside the main body. At this time, the sealing plug moves towards the top of the air extraction chamber under the pressure inside the main body to open the air inlet hole. The gas inside the main body is sucked into the air extraction chamber and then discharged to the outside of the main body through the exhaust hole. After the air extraction is completed, the rotation of the air extraction component is stopped. The air pressure in the air extraction chamber is higher than the air pressure inside the main body, and the sealing plug seals the air inlet hole. At this time, the inside of the main body is not in communication with the outside of the main body, and external air will not enter the inside of the main body, which can effectively prevent the materials inside the main body from getting damp and mildewing.

[0009] In an optional embodiment, the air extraction component includes:

[0010] A rotating component for driving the air flow in the air extraction chamber when rotating, so that the air flow rate in the air extraction chamber is greater than the air flow rate inside the main body, and an air flow path is formed between the air inlet hole and the exhaust hole;

[0011] A driving component for driving the rotating component to rotate.

[0012] Beneficial effects: After the material is placed inside the main body, the driving component is made to work. The driving component drives the rotating component to rotate. When the rotating component rotates, it drives the air flow in the air extraction cavity, so that the air flow rate in the air extraction cavity is greater than the air flow rate inside the main body. Therefore, the air pressure in the air extraction cavity is less than the air pressure inside the main body. The sealing plug moves towards the top of the air extraction cavity under the pressure inside the main body to open the air inlet hole. Since an air flow path is formed between the air inlet hole and the air outlet hole, the gas inside the main body is sucked into the air extraction cavity and then discharged to the outside of the main body through the air outlet hole. After the air extraction is completed, the rotation of the air extraction component is stopped. The air pressure in the air extraction cavity is higher than the air pressure inside the main body, and the sealing plug seals the air inlet hole. At this time, the inside of the main body is not connected to the outside of the main body, and external air will not enter the inside of the main body, which can effectively prevent the material inside the main body from getting damp and moldy.

[0013] In an alternative embodiment, the rotating component includes a first rotating member and a second rotating member both in the shape of an "8".

[0014] Beneficial effects: The rotating component includes a first rotating member and a second rotating member both in the shape of an "8", which can ensure that an air flow path is formed between the air inlet hole and the air outlet hole when the rotating component rotates, and the air flow can only flow from the air inlet hole to the air outlet hole.

[0015] In an alternative embodiment, when one of the first rotating member and the second rotating member rotates to be parallel to the width direction of the air extraction cavity, one end of the other of the first rotating member and the second rotating member is located at the middle position of one of the first rotating member and the second rotating member, and there is a rotation gap between the first rotating member and the second rotating member.

[0016] Beneficial effects: The rotation gap between the first rotating member and the second rotating member can prevent mutual wear between them. When one of the first rotating member and the second rotating member rotates to be parallel to the width direction of the air extraction cavity, one end of the other of the first rotating member and the second rotating member is located at the middle position of one of the first rotating member and the second rotating member, which can enable the air extraction component to continuously suck the air inside the main body into the air extraction cavity and then discharge it to the outside of the main body through the air outlet hole.

[0017] In an alternative embodiment, the driving component drives the first rotating member and the second rotating member to rotate in opposite directions.

[0018] Beneficial effects: The first rotating member and the second rotating member rotate in opposite directions, which can ensure that the gas is evenly sucked into the air extraction cavity and discharged through the air outlet hole, reduce the pulsation and fluctuation of the gas flow rate, reduce the generation of noise and vibration, and thus improve the working efficiency.

[0019] In an alternative embodiment, the driving component includes:

[0020] An operating part and a transmission part, the operating part is in transmission connection with the transmission part, the operating part is driven to move to drive the transmission part to operate, and the operation of the transmission part further drives the rotating assembly to rotate.

[0021] Advantageous effects: The driving assembly includes an operating part and a transmission part. The user can control the movement of the operating part. The movement of the operating part drives the transmission part to operate, and further drives the rotating assembly to rotate. The setting of the operating part facilitates the user to drive the rotating assembly to rotate.

[0022] In an alternative embodiment, the rotating assembly includes a first rotating member and a second rotating member both in the shape of an "8".

[0023] The operation of the transmission part drives the first rotating member and the second rotating member to rotate in opposite directions.

[0024] Advantageous effects: By controlling the movement of the operating part, the movement of the operating part drives the transmission part to operate, so that the first rotating member and the second rotating member both in the shape of an "8" rotate in opposite directions, which can ensure that an air flow path is formed between the air inlet hole and the air outlet hole when the rotating assembly rotates, and the air flow can only flow from the air inlet hole to the air outlet hole.

[0025] In an alternative embodiment, the transmission part includes a driving gear coaxially connected to the first rotating member;

[0026] A driven gear coaxially connected to the second rotating member, the driven gear meshes with the driving gear;

[0027] The driven movement of the operating part drives one of the driving gear or the driven gear to rotate, thereby driving the other of the driving gear or the driven gear to rotate, and further causing the first rotating member and the second rotating member to rotate in opposite directions.

[0028] Advantageous effects: The user manipulates the operating part to move the operating part, driving one of the driving gear and the driven gear to rotate, thereby driving the other of the driving gear and the driven gear to rotate. Since the driving gear and the driven gear mesh, the rotation directions of the driving gear and the driven gear are opposite, and further the first rotating member and the second rotating member can be made to rotate in opposite directions, ensuring that an air flow path is formed between the air inlet hole and the air outlet hole when the rotating assembly rotates, and the air flow can only flow from the air inlet hole to the air outlet hole.

[0029] In an alternative embodiment, the transmission part further includes an outer gear coaxially arranged with the driving gear, and the diameter of the outer gear is larger than the diameter of the driving gear;

[0030] The operating part is in transmission connection with the external gear. The operating part is driven to move, driving the external gear to rotate, thereby causing the driving gear to rotate, and then driving the driven gear to rotate, so that the first rotating part and the second rotating part rotate in opposite directions.

[0031] Advantageous effects: When the user manipulates the operating part to move, it drives the external gear to rotate. Since the external gear and the driving gear are coaxially arranged, the driving gear rotates in the same direction as the external gear, and then drives the driven gear to rotate, so that the first rotating part and the second rotating part rotate in opposite directions, ensuring that an air flow path is formed between the air inlet hole and the air outlet hole when the rotating assembly rotates, and the air flow can only flow from the air inlet hole to the air outlet hole. Since the diameter of the external gear is larger than that of the driving gear, it is more labor-saving for the user to manipulate the operating part.

[0032] In an optional implementation manner, the transmission part further includes an internal gear meshing with the external gear, and the operating part is fixedly connected to the internal gear;

[0033] The operating part is driven to move, driving the internal gear to rotate, and the rotation of the internal gear drives the external gear to rotate, and then drives the driving gear to rotate.

[0034] Advantageous effects: Since the operating part is fixedly connected to the internal gear, when the operating part is driven to move, it will drive the internal gear to rotate. The internal gear meshes with the external gear, driving the external gear to rotate. The external gear and the driving gear are coaxially arranged, so the driving gear rotates in the same direction as the external gear, and then drives the driven gear to rotate, so that the first rotating part and the second rotating part rotate in opposite directions, ensuring that an air flow path is formed between the air inlet hole and the air outlet hole when the rotating assembly rotates, and the air flow can only flow from the air inlet hole to the air outlet hole.

[0035] In an optional implementation manner, the transmission part includes a circular cover body, the internal gear is arranged on the annular inner wall of the circular cover body, and the circular cover body covers the driving gear, the driven gear and the external gear.

[0036] Advantageous effects: The user rotates the circular cover body by manipulating the operating part. Since the internal gear is arranged on the annular inner wall of the circular cover body, it will drive the internal gear to rotate. The internal gear meshes with the external gear, driving the external gear to rotate. Since the circular cover body covers the driving gear, the driven gear and the external gear, the external gear, the driving gear and the driven gear cannot be seen in appearance, and the structure is more beautiful.

[0037] In an optional implementation manner, the operating part is a handle and is fixedly connected to the circular cover body, and the handle is driven to drive the circular cover body to rotate.

[0038] Advantageous effects: When the user manipulates the handle, it drives the circular cover body to rotate. The setting of the handle is convenient for the user to apply force.

[0039] In an alternative embodiment, the connection between the handle and the circular cover body is eccentrically arranged with respect to the central axis of the circular cover body.

[0040] Advantageous effects: Since the connection between the handle and the circular cover body is eccentrically arranged with respect to the central axis of the circular cover body, it is more labor-saving for the user to manipulate the handle to drive the cover body.

[0041] In an alternative embodiment, the exhaust hole is arranged on the circular cover body.

[0042] Advantageous effects: The exhaust hole is arranged on the circular cover body, that is, the exhaust hole is located at the top of the air extraction cavity, which is more convenient for the gas to uniformly discharge from the air extraction cavity.

[0043] In an alternative embodiment, the transmission part includes a driving gear and a driven gear that are coaxially arranged with the first rotating part and the second rotating part respectively;

[0044] The operation part is driven to move to drive one of the driving gear and the driven gear to rotate, thereby driving the other of the driving gear and the driven gear to rotate, and further causing the first rotating part and the second rotating part to rotate in opposite directions.

[0045] Advantageous effects: The user manipulates the operation part to move it, driving one of the driving gear and the driven gear to rotate, thereby driving the other of the driving gear and the driven gear to rotate. Since the driving gear and the driven gear are meshed, the rotation directions of the driving gear and the driven gear are opposite. Further, the first rotating part and the second rotating part can be caused to rotate in opposite directions, ensuring that an air flow path is formed between the air inlet hole and the air outlet hole when the rotating assembly rotates, and the air flow can only flow from the air inlet hole to the air outlet hole.

[0046] In an alternative embodiment, the air extraction cavity includes an air inlet side and an air outlet side, the air inlet hole is arranged on the air inlet side, and the air outlet hole is arranged on the air outlet side.

[0047] Advantageous effects: The air extraction cavity includes an air inlet side and an air outlet side, the air inlet hole is arranged on the air inlet side, and the air outlet hole is arranged on the air outlet side, which can ensure that the air flow can only flow from the air inlet hole to the air outlet hole.

[0049] Beneficial effects: Since the intake side and the exhaust side are arranged on opposite sides of the air extraction cavity, and the intake hole is arranged on the bottom wall of the intake side, and the exhaust hole is arranged on the top wall of the exhaust side, the gas flows upward from the inside of the main body, enters the air extraction cavity through the intake hole, and then flows upward under the drive of the rotating assembly and is discharged from the exhaust hole at the top of the main body, ensuring that the air flow can only flow from the intake hole to the exhaust hole.

[0050] In an alternative embodiment, the air extraction device further comprises:

[0051] A housing, the inner cavity of the housing forms the air extraction cavity;

Detailed implementation manners

[0079] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0080] Many families store the bought rice in a rice bucket. When taking rice, they open the rice bucket cover and scoop out the rice with a container. The rice bucket is in communication with the external air. The rice in the rice bucket is in contact with the air for a long time, and it is easy to get infested with insects and get damp and moldy. Eating moldy rice will seriously endanger human health.

[0081] The following will describe the embodiments of the present utility model in conjunction with Figures 1 to 16 .

[0082] According to an embodiment of the present utility model, a storage structure is provided, and the storage structure can be used to store various materials such as cereal grains and dried fruits.

[0083] In one embodiment, the storage structure includes a main body 9 and an air extraction device. Among them, the main body 9 is used for storing materials; the air extraction device has an air extraction chamber 102 and an air extraction component disposed in the air extraction chamber 102. The air extraction chamber 102 is communicated with the inside of the main body 9 through an air inlet hole 103, and the air extraction chamber 102 is communicated with the outside of the main body 9 through an exhaust hole 501; a sealing plug 7 is provided at the air inlet hole 103. When the air extraction component is driven to rotate so that the air pressure in the air extraction chamber 102 is less than the air pressure inside the main body 9, the sealing plug 7 moves in the direction of the top of the air extraction chamber 102 under the pressure inside the main body 9 to open the air inlet hole 103, and then the gas inside the main body 9 is sucked into the air extraction chamber 102 and discharged through the exhaust hole 501.

[0084] In this embodiment, after the materials are placed inside the main body 9, the air extraction component is driven to rotate so that the air pressure in the air extraction chamber 102 is less than the air pressure inside the main body 9. At this time, the sealing plug 7 moves in the direction of the top of the air extraction chamber 102 under the pressure inside the main body 9 to open the air inlet hole 103. The gas inside the main body 9 is sucked into the air extraction chamber 102 and then discharged to the outside of the main body 9 through the exhaust hole 501. After the air extraction is completed, the rotation of the air extraction component is stopped. The air pressure in the air extraction chamber 102 is higher than the air pressure inside the main body 9, and the sealing plug 7 seals the air inlet hole 103. At this time, the inside of the main body 9 is not communicated with the outside of the main body 9, and external air will not enter the inside of the main body 9, which can effectively prevent the materials inside the main body 9 from getting damp and moldy.

[0085] In one embodiment, the air extraction component includes a rotating component and a driving component. The rotating component is used to drive the air flow in the air extraction chamber 102 when rotating, so that the air flow rate in the air extraction chamber 102 is greater than the air flow rate inside the main body 9, and an air flow path is formed between the air inlet hole 103 and the exhaust hole 501; the driving component is used to drive the rotating component to rotate.

[0086] In this embodiment, after the materials are placed inside the main body 9, the driving component is made to work. The driving component drives the rotating component to rotate. When the rotating component rotates, it drives the air flow in the air extraction chamber 102, so that the air flow rate in the air extraction chamber 102 is greater than the air flow rate inside the main body 9. Therefore, the air pressure in the air extraction chamber 102 is less than the air pressure inside the main body 9. The sealing plug 7 moves in the direction of the top of the air extraction chamber 102 under the pressure inside the main body 9 to open the air inlet hole 103. Since an air flow path is formed between the air inlet hole 103 and the exhaust hole 501, the gas inside the main body 9 is sucked into the air extraction chamber 102 and then discharged to the outside of the main body 9 through the exhaust hole 501. After the air extraction is completed, the rotation of the air extraction component is stopped. The air pressure in the air extraction chamber 102 is higher than the air pressure inside the main body 9, and the sealing plug 7 seals the air inlet hole 103. At this time, the inside of the main body 9 is not communicated with the outside of the main body 9, and external air will not enter the inside of the main body 9, which can effectively prevent the materials inside the main body 9 from getting damp and moldy.

[0087] In one embodiment, the rotating assembly includes a first rotating member 105 and a second rotating member 106 both in the shape of an "8".

[0088] In this embodiment, the rotating assembly includes a first rotating member 105 and a second rotating member 106 both in the shape of an "8", which can ensure that an air flow path is formed between the air inlet hole 103 and the exhaust hole 501 when the rotating assembly rotates, and the air flow can only flow from the air inlet hole 103 to the exhaust hole 501.

[0089] In other alternative embodiments, the rotating assembly can be of other shapes, as long as the air pressure in the air extraction cavity 102 can be made less than the air pressure inside the main body 9 when rotating.

[0090] In one embodiment, when one of the first rotating member 105 and the second rotating member 106 rotates to be parallel to the width direction of the air extraction cavity 102, one end of the other of the first rotating member 105 and the second rotating member 106 is located at the middle position of one of the first rotating member 105 and the second rotating member 106, and there is a rotating gap between the first rotating member 105 and the second rotating member 106.

[0091] In this embodiment, the existence of a rotating gap between the first rotating member 105 and the second rotating member 106 can prevent mutual wear between them. When one of the first rotating member 105 and the second rotating member 106 rotates to be parallel to the width direction of the air extraction cavity 102, one end of the other of the first rotating member 105 and the second rotating member 106 is located at the middle position of one of the first rotating member 105 and the second rotating member 106, which can enable the air extraction assembly to continuously pump the air inside the main body 9 into the air extraction cavity 102 and then discharge it to the outside of the main body 9 through the exhaust hole 501.

[0092] Specifically, as Figure 12 shown, when the second rotating member 106 rotates to be parallel to the width direction of the air extraction cavity 102, one end of the first rotating member 105 is located at the middle position of the second rotating member 106. The first rotating member 105 and the second rotating member 106 have the same rotation speed. When the first rotating member 105 rotates to be parallel to the width direction of the air extraction cavity 102, one end of the second rotating member 106 is located at the middle position of the first rotating member 105.

[0093] In one embodiment, the driving assembly drives the first rotating member 105 and the second rotating member 106 to rotate in opposite directions.

[0094] In this embodiment, the first rotating member 105 and the second rotating member 106 rotate in opposite directions, which can ensure that the gas is evenly inhaled into the air extraction cavity 102 and discharged through the exhaust hole 501, reduce the pulsation and fluctuation of the gas flow rate, and reduce the generation of noise and vibration, thereby improving the working efficiency.

[0095] Specifically, in one embodiment, the first rotating member 105 rotates in the clockwise direction, and the second rotating member 106 rotates in the counterclockwise direction; alternatively, the first rotating member 105 rotates in the counterclockwise direction, and the second rotating member 106 rotates in the clockwise direction.

[0096] In one embodiment, the driving assembly includes an operating part and a transmission part. The operating part is in transmission connection with the transmission part. The operating part is driven to move to drive the transmission part to operate, and the transmission part operates to drive the rotating assembly to rotate.

[0097] In this embodiment, the driving assembly includes an operating part and a transmission part. The user can control the movement of the operating part. The movement of the operating part drives the transmission part to operate, and further drives the rotating assembly to rotate. The setting of the operating part facilitates the user to drive the rotating assembly to rotate.

[0098] In one embodiment, the rotating assembly includes a first rotating member 105 and a second rotating member 106 both in the shape of an "8"; the operation of the transmission part drives the first rotating member 105 and the second rotating member 106 to rotate in opposite directions.

[0099] In this embodiment, the user controls the movement of the operating part. The movement of the operating part drives the transmission part to operate, so that the first rotating member 105 and the second rotating member 106 both in the shape of an "8" rotate in opposite directions, which can ensure that an air flow path is formed between the air inlet hole 103 and the exhaust hole 501 when the rotating assembly rotates, and the air flow can only flow from the air inlet hole 103 to the exhaust hole 501.

[0100] In one embodiment, the transmission part includes a driving gear 2 and a driven gear 3. The driving gear 2 is coaxially connected with the first rotating member 105, the driven gear 3 is coaxially connected with the second rotating member 106, and the driven gear 3 meshes with the driving gear 2; the operating part is driven to move to drive one of the driving gear 2 and the driven gear 3 to rotate, thereby driving the other of the driving gear 2 and the driven gear 3 to rotate, and further causing the first rotating member 105 and the second rotating member 106 to rotate in opposite directions.

[0101] In this embodiment, the user manipulates the operating part to move the operating part, driving one of the driving gear 2 and the driven gear 3 to rotate, thereby driving the other of the driving gear 2 and the driven gear 3 to rotate. Since the driving gear 2 and the driven gear 3 mesh, the rotation directions of the driving gear 2 and the driven gear 3 are opposite. Further, the first rotating member 105 and the second rotating member 106 can be caused to rotate in opposite directions, ensuring that an air flow path is formed between the air inlet hole 103 and the exhaust hole 501 when the rotating assembly rotates, and the air flow can only flow from the air inlet hole 103 to the exhaust hole 501.

[0102] Specifically, in one embodiment, when the operating part is driven to move, it drives the driving gear 2 to rotate, and further drives the driven gear 3 to rotate.

[0103] In one embodiment, the transmission part further includes an external gear 4 coaxially arranged with the driving gear 2, and the diameter of the external gear 4 is larger than that of the driving gear 2; the operating part is in transmission connection with the external gear 4, and the operating part is driven to move to drive the external gear 4 to rotate, thereby causing the driving gear 2 to rotate, and then driving the driven gear 3 to rotate, so that the first rotating member 105 and the second rotating member 106 rotate in opposite directions.

[0104] In this embodiment, the user manipulates the operating part to move, driving the external gear 4 to rotate. Since the external gear 4 is coaxially arranged with the driving gear 2, the driving gear 2 rotates in the same direction as the external gear 4, and then drives the driven gear 3 to rotate, so that the first rotating member 105 and the second rotating member 106 rotate in opposite directions, ensuring that an air flow path is formed between the air inlet hole 103 and the exhaust hole 501 when the rotating assembly rotates, and the air flow can only flow from the air inlet hole 103 to the exhaust hole 501. Since the diameter of the external gear 4 is larger than that of the driving gear 2, it is more labor-saving for the user to manipulate the operating part.

[0105] In one embodiment, the transmission part further includes an internal gear meshing with the external gear 4, and the operating part is fixedly connected to the internal gear; the operating part is driven to move to drive the internal gear to rotate, and the rotation of the internal gear drives the external gear 4 to rotate, and then drives the driving gear 2 to rotate.

[0106] In this embodiment, since the operating part is fixedly connected to the internal gear, the operating part will drive the internal gear to rotate when it is driven to move. The internal gear meshes with the external gear 4, driving the external gear 4 to rotate. The external gear 4 is coaxially arranged with the driving gear 2, so the driving gear 2 rotates in the same direction as the external gear 4, and then drives the driven gear 3 to rotate, so that the first rotating member 105 and the second rotating member 106 rotate in opposite directions, ensuring that an air flow path is formed between the air inlet hole 103 and the exhaust hole 501 when the rotating assembly rotates, and the air flow can only flow from the air inlet hole 103 to the exhaust hole 501. Since the diameter of the external gear 4 is larger than that of the driving gear 2, it is more labor-saving for the user to manipulate the operating part.

[0107] In one embodiment, the transmission part includes a circular cover body 5, the internal gear is arranged on the annular inner wall of the circular cover body 5, and the circular cover body 5 covers the driving gear 2, the driven gear 3 and the external gear 4.

[0108] In this embodiment, the user manipulates the operating part to rotate the circular cover body 5. Since the internal gear is arranged on the annular inner wall of the circular cover body 5, the internal gear will be driven to rotate, and the internal gear meshes with the external gear 4, driving the external gear 4 to rotate. Since the circular cover body 5 covers the driving gear 2, the driven gear 3 and the external gear 4, the external gear 4, the driving gear 2 and the driven gear 3 cannot be seen on the appearance, and the structure is more beautiful.

[0109] In one embodiment, the operating part is a handle 6, which is fixedly connected to the circular cover 5, and the handle 6 is driven to drive the circular cover 5 to rotate.

[0111] In one embodiment, the connection part between the handle 6 and the circular cover 5 is eccentrically arranged relative to the central axis of the circular cover 5.

[0112] In this embodiment, since the connection part between the handle 6 and the circular cover 5 is eccentrically arranged relative to the central axis of the circular cover 5, it is more labor-saving for the user to manipulate the handle 6 to drive the cover.

[0116] In this embodiment, the user manipulates the operating part to move it, driving one of the driving gear 2 and the driven gear 3 to rotate, thereby driving the other one of the driving gear 2 and the driven gear 3 to rotate. Since the driving gear 2 and the driven gear 3 are meshed, the rotation directions of the driving gear 2 and the driven gear 3 are opposite. Furthermore, the first rotating part 105 and the second rotating part 106 can be enabled to rotate in opposite directions, ensuring that an air flow path is formed between the air inlet hole 103 and the exhaust hole 501 when the rotating assembly rotates, and the air flow can only flow from the air inlet hole 103 to the exhaust hole 501.
