Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a dust-proof structure of a transmission part, an air guide plate transmission mechanism and an air conditioner. Background Art

[0002] In modern home environments, air conditioners are important devices for regulating indoor temperature. Their performance and user experience are directly related to consumer satisfaction. With the advancement of technology and the improvement of people's quality of life, the design of air conditioners is becoming more and more intelligent, humanized and efficient. Among them, preventing cold air from blowing directly on the human body has become an important consideration in air conditioner design, especially for the elderly, children and the weak, as direct cold air can easily cause physical discomfort.

[0003] In order to prevent direct blowing, other air ducts will be set on the air conditioner to guide the airflow to be released from the direction that is not directly blowing on people. Correspondingly, in order to facilitate the adjustment of the air duct, a corresponding transmission structure will be set to adjust the air duct. In order to prevent the transmission structure from being exposed to the outside, coupled with the limited internal assembly space of the air conditioner, it is inevitable that part of the transmission structure will be located in the air duct. Inside the air duct, the transmission parts and other moving parts in the transmission structure will be directly exposed to the airflow. Since the air conditioner will inhale a large amount of air during operation, this air often carries various dust particles. When these dust particles enter the air duct with the air flow and contact the transmission structure, they will gradually accumulate at the transmission of the transmission structure. As the dust accumulates, the wear between the transmission structures will increase, and even jamming may occur. Summary of the invention

[0004] In order to overcome at least one of the defects of the prior art described above, the present invention provides a transmission member dustproof structure, an air guide plate transmission mechanism and an air conditioner, which can solve the dust accumulation problem caused by the transmission member located on the air outlet duct of the air conditioner.

[0005] The technical solution adopted by the present invention to solve the problem is:

[0006] A transmission part dustproof structure is provided on an air outlet path of an air conditioner, comprising:

[0007] Transmission body;

[0008] A dustproof member, the dustproof member having a windward surface and a leeward surface opposite to the windward surface, the windward surface being a side facing the wind outlet direction of the wind outlet path, the transmission part of the transmission member body being located on the windward surface of the transmission member body, and the transmission member body being arranged on the leeward side of the dustproof member;

[0009] Among them, the secondary flow formed after the air outlet of the air conditioner passes through the dustproof part forms a confluence in the direction away from the dustproof part, and the transmission part body is located between the dustproof part and the confluence of the secondary flow, so that the secondary flow formed after the air outlet of the air conditioner passes through the dustproof part and passes over the transmission part body toward the side wall of the dustproof part.

[0010] By adopting the above scheme, when the airflow encounters the dustproof part, a secondary flow will be formed. These secondary flows form a specific airflow field in the direction of the dustproof part toward the transmission part body. The specific airflow field forms a cavity area and a wake area on the leeward side of the dustproof part. The flow velocity in the cavity area is low, and due to the influence of air viscosity, the airflow velocity near the side wall of the transmission part body is even lower, resulting in a strong vortex in the cavity area. These vortices interfere with the entry of external airflow and make it difficult for the airflow to flow stably in the cavity area. Combined with the Coanda effect, the fluid tends to flow along the surface of the object, which further hinders the airflow from entering the cavity area. Therefore, when the transmission part body is located in the cavity area formed after the dustproof part blocks the flow, it is difficult for the airflow to directly impact the transmission part body, effectively reducing the accumulation of dust. Correspondingly, the design of the dustproof part reduces the interference of dust on the transmission part body, ensuring the smoothness and reliability of the transmission part during long-term operation. This not only improves the transmission efficiency, but also reduces the risk of jamming caused by dust, ensuring the normal operation of the air conditioner.

[0011] Furthermore, a spacing S is set between the transmission component body and the dustproof component, the thickness of the dustproof component is T, and the relationship between S and T is: S=(5~20)T, so that the airflow of the air outlet path passes over the transmission component body.

[0012] By adopting the above solution and setting the distance S=(5-20)T between the transmission member body and the dustproof member, it can be ensured that the transmission member body is just located in the cavity area formed by the dustproof member.

[0013] Furthermore, the transmission member body includes a transmission arm and a fan-shaped toothed disc, the transmission arm is fixedly connected to the fan-shaped toothed disc, the fan-shaped toothed disc is used for transmission connection with an external driving member, and the transmission arm and the fan-shaped toothed disc are both located on the leeward side of the dust-proof member, so that the secondary flow formed after passing through the dust-proof member passes over the transmission arm toward the side wall of the dust-proof member and the fan-shaped toothed disc toward the side wall of the dust-proof member.

[0014] By adopting the above solution, the transmission member body is designed to include a transmission arm and a sector-shaped toothed disc, and the transmission arm is fixedly connected to the sector-shaped toothed disc, so that the entire transmission member body is located on the leeward side of the dustproof member. When the airflow passes through the dustproof member, since the transmission arm and the sector-shaped toothed disc are both located on the leeward side of the dustproof member, the secondary flow formed by the airflow after passing through the dustproof member will pass over the transmission arm and the sector-shaped toothed disc toward the side wall of the dustproof member. This makes the transmission arm and the sector-shaped toothed disc almost unaffected by the dust in the airflow, greatly reducing the accumulation of dust.

[0015] Furthermore, the thickness of the transmission component body is less than or equal to the thickness of the dustproof component.

[0016] By adopting the above solution, by designing the thickness of the transmission body to be less than or equal to the thickness of the dustproof member, it can be ensured that the transmission body is completely located within the protection range of the dustproof member. Since the thickness of the transmission body is small, the secondary flow formed by the airflow after passing through the dustproof member can more easily pass over the transmission body toward the side wall of the dustproof member, so that the transmission body is almost not directly affected by the dust in the airflow. This greatly reduces the accumulation of dust on the transmission body, especially for key components such as the transmission arm and the fan-shaped toothed disc, providing better protection.

[0017] Furthermore, the transmission member body and the dustproof member are arranged in parallel.

[0018] By adopting the above solution, by arranging the transmission component body and the dustproof component in parallel, it can be ensured that the transmission component body is completely located within the protection range of the dustproof component, which is also convenient for the subsequent installation of other transmission components.

[0019] Furthermore, the transmission component body and the dust-proof component are both crank connecting rods.

[0020] By adopting the above solution, the transmission body and the dustproof part are both crank connecting rods. This design simplifies the structure and makes the installation of other drive components more convenient. The standardized design of the crank connecting rod makes the connection and assembly between the components simpler, reduces the installation time and cost, and improves the production efficiency. At the same time, this design is also convenient for subsequent maintenance and replacement, further improving the reliability of the system.

[0021] The present invention also provides an air deflector transmission mechanism, which adopts the above-mentioned transmission member dustproof structure, including a driving assembly and a transfer connecting rod, the driving assembly includes a driver and a driving member, the driver is transmission-connected to the driving member, one end of the transmission member body is transmission-connected to the driving member, and the other end is rotationally connected to the transfer connecting rod, a rotation connecting shaft is provided in the middle of the transmission member body, so that the transmission member body rotates around the rotation connecting shaft, one end of the dustproof member is rotationally connected to an external mounting carrier, and the other end is rotationally connected to the transfer connecting rod, and the transfer connecting rod is fixedly connected to a panel;

[0022] The driving member drives the transmission member body to rotate around the rotating connecting shaft to drive the transfer link and the panel to move up and down and forward and backward in an arc track. When the transfer link moves, the transfer link drives the dustproof member and the transmission member body to move synchronously.

[0023] By adopting the above scheme and the transmission dustproof structure, the transmission body and the dustproof part in the air guide plate transmission mechanism are designed as crank connecting rods to ensure that the transmission body is always within the protection range of the dustproof part during movement. When the airflow passes through the dustproof part, the secondary flow formed can effectively pass over the transmission body, reducing the accumulation of dust, especially for key parts such as the transmission arm and the fan-shaped gear plate, providing better protection. And the transmission body and the dustproof part cooperate to drive the transfer connecting rod to move up and down and forward and backward, thereby realizing the forward and upward movement of the panel.

[0024] Furthermore, the driving member is an output gear, and the output gear is meshed with the sector-shaped gear disk.

[0025] By adopting the above solution, the meshing design of the output gear and the fan-shaped toothed disc makes the transmission ratio fixed, which can achieve precise motion control. This helps to improve the position accuracy of the wind deflector, ensure accurate adjustment of the wind direction, and further enhance the user experience.

[0026] Furthermore, there are multiple dust-proof parts, all of which are arranged parallel to the transmission part body, and all of which are rotatably connected to the external carrier at one end and rotatably connected to the transfer connecting rod at the other end. The secondary flow formed by the air flow out of the air conditioner passing through the dust-proof parts close to the transmission part body passes over the transmission part body toward the side wall of the dust-proof parts.

[0027] By adopting the above solution, in some specific environments, such as when the air conditioner is large in size, it is necessary to set up multiple dustproof parts accordingly, and multiple dustproof parts make the entire transmission structure more stable. Each dustproof part is arranged in parallel with the transmission part body, and one end is rotatably connected to the external carrier, and the other end is rotatably connected to the transfer connecting rod. This design ensures that the transmission parts can maintain coordination during the movement, avoids additional wear and failure caused by asynchronous movement, and improves the reliability and stability of the system.

[0028] The present invention further provides an air conditioner, which adopts the above-mentioned air guide plate transmission mechanism and comprises a middle frame, wherein the air guide plate transmission mechanism is assembled on a side of the middle frame facing the air outlet.

[0029] In summary, the transmission member dustproof structure, air guide plate transmission mechanism and air conditioner provided by the present invention have the following technical effects:

[0030] When the airflow encounters the dustproof part, secondary flow will be formed. These secondary flows form a specific airflow field behind the leeward side of the dustproof part, that is, in the direction of the dustproof part toward the transmission part body. This specific airflow field forms a cavity area and a wake area in the rear area of ​​the leeward side of the dustproof part, which is the confluence area of ​​the secondary flow. Due to the low flow velocity in the cavity area and the influence of air viscosity, the airflow velocity near the side wall of the transmission part body is even lower, resulting in the formation of strong vortices in the cavity area. These vortices will interfere with the entry of external airflow and cause the airflow in the cavity area to form a stable reflux in the cavity area. Combined with the Coanda effect, the fluid tends to flow along the surface of the object, which further hinders the external airflow from entering the cavity area. Therefore, when the transmission part body is located in the cavity area formed after the dustproof part blocks the flow, it is difficult for the external secondary flow to directly impact the transmission part body, effectively reducing the accumulation of dust on the transmission part body. Correspondingly, the design of the dustproof part reduces the interference of dust on the transmission part body, ensuring the smoothness and reliability of the transmission part in long-term operation. This not only improves transmission efficiency, but also reduces the risk of jamming due to dust, ensuring the normal operation of the air conditioner. BRIEF DESCRIPTION OF THE DRAWINGS

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0043] See also Figure 1-Figure 7 The present invention discloses a transmission dust-proof structure, which is arranged on the air outlet path of the air conditioner 5, and includes a transmission body 1 and a dust-proof member 2, the dust-proof member 2 having a windward surface 21 and a leeward surface 22 opposite to the windward surface 21, the windward surface 21 is the side of the air outlet direction facing the air outlet path, the transmission body 1 is arranged on the leeward surface 22 side of the dust-proof member 2, wherein the secondary flow formed after the air outlet of the air conditioner 5 passes through the dust-proof member 2 forms a confluence in the direction away from the dust-proof member 2, the transmission part of the transmission body 1 is located on the windward surface of the transmission body 1, and the transmission body 1 is located between the dust-proof member 2 and the confluence of the secondary flow, so that the secondary flow formed after the air outlet of the air conditioner 5 passes through the dust-proof member 2 passes over the transmission body 1 toward the side wall of the dust-proof member 2.

[0044] Specifically, the dustproof member 2 has a windward surface 21 and a leeward surface 22 opposite to the windward surface 21, wherein the windward surface 21 is the direction of the dustproof member 2 toward the air outlet of the air conditioner 5, and the leeward surface 22 is the side opposite to the windward surface 21, and the transmission member body 1 is arranged on the leeward surface 22 side of the dustproof member 2, that is, the dustproof member 2 and the transmission member body 1 are arranged along the flow direction of the airflow discharged from the air conditioner 5, and the airflow will first pass through the dustproof member 2 and then flow toward the transmission member body 1. There is a distance between the transmission member body 1 and the dustproof member 2, so that the secondary flow formed after the airflow discharged from the air conditioner 5 passes through the dustproof member 2 passes over the side wall of the transmission member body 1 toward the dustproof member 2.

[0045] The principle of providing a gap between the transmission body 1 and the dustproof member 2 so that the secondary flow formed by the air flow from the air conditioner 5 passing through the dustproof member 2 passes over the transmission body 1 toward the side wall of the dustproof member 2 is as follows:

[0046] When the airflow encounters the dustproof part 2, a secondary flow is formed. These secondary flows form a specific airflow field after passing through the dustproof part 2. The specific airflow field forms a cavity area and a wake area on the leeward side 22 of the dustproof part 2. The flow velocity in the cavity area is relatively low, and due to the influence of air viscosity, the airflow velocity near the side wall of the transmission body 1 is even lower, resulting in a strong vortex in the cavity area. These vortices interfere with the entry of external airflow and make it difficult for the airflow to flow stably in the cavity area. Combined with the Coanda effect, the fluid tends to flow along the surface of the object, which further hinders the airflow from entering the cavity area. Therefore, when the transmission body 1 is located in the cavity area formed after the dustproof part 2 blocks the flow, it is difficult for the airflow to directly impact the transmission body 1, effectively reducing the accumulation of dust. Correspondingly, the design of the dustproof part 2 reduces the interference of dust on the transmission body 1, ensuring the smoothness and reliability of the transmission during long-term operation. This not only improves the transmission efficiency, but also reduces the risk of jamming caused by dust, ensuring the normal operation of the air conditioner 5.

[0047] participate Figure 1 and Figure 2 As shown, in some embodiments, a spacing S is set between the transmission component body 1 and the dustproof component 2, the thickness of the dustproof component 2 is T, and the relationship between S and T is: S=(5~20)T, so that the airflow of the air outlet path passes over the transmission component body 1.

[0048] Specifically, the thickness of the dustproof member 2 is equal to the width of its windward surface 21. Since the dustproof member 2 also needs to play a certain auxiliary role in the transmission structure, if the distance between the dustproof member 2 and the transmission member body 1 is too small, it will be unfavorable for the assembly and stable transmission of other transmission components. If the distance between the dustproof member 2 and the transmission member body 1 is too large, the secondary flow formed after passing through the dustproof member 2 will pass over the transmission member body 1 toward the side wall of the dustproof member 2. By setting the distance S between the transmission member body 1 and the dustproof member 2 to (5-20)T, it can be ensured that the transmission member body 1 is just located in the cavity area formed by the dustproof member 2, and the instability in the transmission process will not be caused by the small distance between the dustproof member 2 and the transmission member body 1.

[0049] participate Figure 1 As shown, in some embodiments, the transmission member body 1 includes a transmission arm 11 and a fan-shaped toothed disc 12, the transmission arm 11 is fixedly connected to the fan-shaped toothed disc 12, the fan-shaped toothed disc 12 is used for transmission connection with an external driving member 32, and the transmission arm 11 and the fan-shaped toothed disc 12 are both located on the leeward side 22 of the dustproof member 2, so that the secondary flow formed after passing through the dustproof member 2 passes over the transmission arm 11 toward the side wall of the dustproof member 2 and the fan-shaped toothed disc 12 toward the side wall of the dustproof member 2.

[0050] Specifically, the transmission member body 1 is designed to include a transmission arm 11 and a sector-shaped toothed disc 12, and the transmission arm 11 is fixedly connected to the sector-shaped toothed disc 12, so that the entire transmission member body 1 is located on the leeward side 22 of the dust-proof member 2. When the airflow passes through the dust-proof member 2, since the transmission arm 11 and the sector-shaped toothed disc 12 are both located on the leeward side 22 of the dust-proof member 2, the secondary flow formed by the airflow after passing through the dust-proof member 2 will pass over the transmission arm 11 and the sector-shaped toothed disc 12 toward the side wall of the dust-proof member 2. This makes the transmission arm 11 and the sector-shaped toothed disc 12 almost unaffected by the dust in the airflow, greatly reducing the accumulation of dust.

[0051] participate Figure 1 and Figure 2 As shown, in some embodiments, the thickness of the transmission member body 1 is less than or equal to the thickness of the dustproof member 2 .

[0052] Specifically, by designing the thickness of the transmission body 1 to be less than or equal to the thickness of the dustproof member 2, it can be ensured that the transmission body 1 is completely within the protection range of the dustproof member 2. Since the thickness of the transmission body 1 is small, the secondary flow formed by the airflow after passing through the dustproof member 2 can more easily pass over the side wall of the transmission body 1 toward the dustproof member 2, so that the transmission body 1 is almost not directly affected by the dust in the airflow. This greatly reduces the accumulation of dust on the transmission body 1, especially for key components such as the transmission arm 11 and the fan-shaped toothed disc 12, providing better protection.

[0053] participate Figure 1 As shown, in some embodiments, the transmission member body 1 and the dustproof member 2 are arranged in parallel.

[0054] Specifically, by arranging the transmission component body 1 and the dustproof component 2 in parallel, it can be ensured that the transmission component body 1 is completely located within the protection range of the dustproof component 2, which is also convenient for the subsequent installation of other transmission components.

[0055] participate Figure 1 As shown, in some embodiments, the transmission component body 1 and the dustproof component 2 are both crank connecting rods.

[0056] Specifically, the transmission body 1 and the dustproof member 2 are both crank connecting rods. This design simplifies the structure and makes the installation of other drive components 3 more convenient. The standardized design of the crank connecting rod makes the connection and assembly between the components simpler, reduces the installation time and cost, and improves the production efficiency. At the same time, this design is also convenient for subsequent maintenance and replacement, further improving the reliability of the system.

[0057] See also Figure 3-Figure 6 As shown, the present invention also provides a wind deflector transmission mechanism, which adopts the above-mentioned transmission dustproof structure, including a driving assembly 3 and a transfer connecting rod 4, the driving assembly 3 includes a driver 31 and a driving member 32, the driver 31 is transmission-connected with the driving member 32, one end of the transmission member body 1 is transmission-connected with the driving member 32, and the other end is rotationally connected with the transfer connecting rod 4, a rotation connecting shaft 13 is provided in the middle of the transmission member body 1, so that the transmission member body 1 rotates around the rotation connecting shaft 13, one end of the dustproof member 2 is rotationally connected with an external mounting carrier, and the other end is rotationally connected with the transfer connecting rod 4, and the transfer connecting rod 4 is fixedly connected with a panel 51. The driving member 32 drives the transmission member body 1 to rotate around the rotation connecting shaft 13, so as to drive the transfer connecting rod 4 and the panel 51 to move up and down and forward and backward in an arc-shaped trajectory, and when the transfer connecting rod 4 moves, the transfer connecting rod 4 drives the dustproof member 2 to move synchronously with the transmission member body 1.

[0058] Specifically, the driver 31 can be a motor or the like that can drive the driver 32 to drive the transmission body 1 to rotate around the rotation connecting shaft 13. Similarly, the driver 32 can also be a gear, a telescopic rod, etc. that can drive the transmission body 1 to rotate around the rotation connecting shaft 13, and the specific structure is not limited here. The driver 31 is transmission-connected with the driving member 32, and the driving member 32 is transmission-connected with the transmission member body 1. A rotating connecting shaft 13 is provided in the middle of the transmission member body 1, so that the transmission member body 1 can rotate around the rotating connecting shaft 13. The transmission member body 1 is rotationally connected with a transfer connecting rod 4 at one end away from the driving member 32, so that when the driving member 32 drives the transmission member body 1 to rotate around the rotating connecting shaft 13, the transmission member body 1 drives the transfer connecting rod 4 to move forward and upward at one end away from the driving member 32, so that the panel 51 fixed on the transfer connecting rod 4 can achieve forward and upward movement relative to the middle frame 52 of the air conditioner 5, and then form an air duct between the panel 51 and the middle frame 52, and the airflow discharged from the air conditioner 5 is guided by the edges of the panel 51 and the middle frame 52 to achieve horizontal air outlet of the air conditioner 5, thereby achieving the effect of preventing direct blowing. In the process of the driving member 32 driving the transfer link 4 to move through the transmission member body 1, based on the structure that one end of the dustproof member 2 is rotatably connected to the external mounting carrier and the other end is rotatably connected to the transfer link 4, the dustproof member 2 is driven by the transfer link 4 and makes synchronous parallel motion with the transmission member body 1. In addition to reducing dust accumulation on the transmission member body 1, the dustproof member 2 also provides an additional connection point for the transfer link 4, thereby improving the stability of the transfer link 4 and the panel 51 fixedly connected to the transfer link 4 during movement.

[0059] See also Figure 3-Figure 6 As shown, in some embodiments, the driving member 32 is an output gear, and the output gear is meshed with the sector gear plate 12 .

[0060] Specifically, the meshing design of the output gear and the fan-shaped toothed disc 12 makes the transmission ratio fixed, and can achieve precise motion control, which helps to improve the position accuracy of the wind deflector, ensure accurate adjustment of the wind direction, and further enhance the user experience.

[0061] See also Figure 3-Figure 6 As shown, in some embodiments, there are multiple dust-proof parts 2, all of which are arranged in parallel with the transmission part body 1, and all of the dust-proof parts 2 are rotatably connected to the external carrier at one end and rotatably connected to the transfer connecting rod 4 at the other end. The secondary flow formed by the air flow out of the air conditioner 5 after passing through the dust-proof parts 2 close to the transmission part body 1 passes over the transmission part body 1 toward the side wall of the dust-proof parts 2.

[0062] Specifically, in some specific environments, such as when the air conditioner 5 is large in size, multiple dustproof parts 2 need to be provided accordingly, and multiple dustproof parts 2 make the entire transmission structure more stable. Each dustproof part 2 is provided in parallel with the transmission part body 1, and one end is rotatably connected to the external carrier, and the other end is rotatably connected to the transfer connecting rod 4. This design ensures that the transmission parts can maintain coordination during the movement, avoids additional wear and failure caused by asynchronous movement, and improves the reliability and stability of the system.

[0063] See also Figure 3-Figure 6 As shown, as an option, a mounting seat 6 can be provided to facilitate the installation of the drive assembly 3, the transmission body 1 and the dustproof member 2. Specifically, the driver 31 is fixedly mounted on the mounting seat 6, the driver 32 is transmission-connected with the driver 31, and the rotating connecting shaft 13 of the transmission body 1 is rotationally mounted on the mounting seat 6 so that the transmission body 1 can rotate around the rotating connecting shaft 13. The fan-shaped toothed disc 12 of the transmission body 1 is meshed with the driver 32, the dustproof member 2 is arranged in parallel with the transmission body 1, and one end of the dustproof member 2 is rotationally connected with the mounting seat 6, thus completing the structural installation of the mounting seat 6. When it is subsequently installed on the air conditioner 5, it can be adaptively installed according to the size and position of the installation space, etc., which is not limited here.

[0064] See also Figure 3-Figure 6 As shown, the present invention also provides an air conditioner, adopting the above-mentioned air guide plate transmission mechanism, including a middle frame 52, and the air guide plate transmission mechanism is installed on the side of the middle frame 52 facing the air outlet, that is, the air guide plate transmission mechanism is installed on the front side of the middle frame 52.

[0065] Optionally, the middle frame 52 of the air conditioner 5 is also provided with a convex edge 521. When the panel 51 is not opened, the panel 51 sinks into the groove surrounded by the convex edge 521 of the middle frame 52. During the opening process of the panel 51, the driving member 32 drives the transmission member body 1 to rotate around the rotating connecting shaft 13. During the rotation of the transmission member body 1, the transfer link 4 will be driven to make an arc movement forward and upward. While the transfer link 4 moves, the panel 51 moves synchronously with the transfer link 4 to complete the forward and upward movement, thereby achieving the effect of the panel 51 moving away from the middle frame 52 and forming a new air duct between the panel 51 and the middle frame 52.

[0066] After panel 51 is opened, see Figure 7 As shown, the dustproof member 2 and the transmission member body 1 are located in the air duct. When the air conditioner 5 releases airflow, the airflow will first pass through the dustproof member 2. The airflow passing through the dustproof member 2 forms a secondary flow. The secondary flow bypasses the dustproof member 2 and continues to flow toward the transmission member body 1. These secondary flows will merge at a distance S (5 to 20) T. A cavity area is formed between the dustproof member 2 and the secondary flow confluence range, that is, Figure 7In the area A marked in the figure, a specific airflow field will be formed between the dustproof part 2 and the confluence range of the secondary flow. The velocity of this specific airflow field is relatively low, and due to the influence of air viscosity, the velocity of the airflow near the side wall of the transmission part body 1 is even lower, which will form strong vortices in the cavity area. These vortices will interfere with the entry of external airflow and make it difficult for the airflow to flow stably in the cavity area. In addition, according to the Coanda effect, the fluid tends to flow along the surface of the object, which further hinders the airflow from entering the cavity area. Correspondingly, the side wall of the transmission part body 1 facing the dustproof part 2 can be located in the cavity area. Therefore, the side wall of the transmission part body 1 facing the dustproof part 2 can be located in the cavity area, which can effectively reduce the dust in the airflow from directly impacting the transmission part body 1, thereby greatly reducing the accumulation of dust.

[0067] Furthermore, based on the dustproof design of the dustproof member 2 and the transmission member body 1, even if grease is provided on the sector toothed disc 12 of the transmission member body 1, due to the effective protection of the dustproof member 2, only a very small amount of dust will enter the transmission member body 1 area, which will not affect the normal operation of the transmission member body 1. This ensures the lubrication effect of the transmission member body 1 and further extends the service life of the transmission member.

[0068] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
