Description

Technical Field

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

[0002] In modern homes, air conditioners are essential for regulating indoor temperature. Their performance and user experience are directly linked to consumer satisfaction. With technological advancements and rising demands for a better quality of life, air conditioner designs are increasingly becoming more intelligent, user-friendly, and efficient. Preventing direct cold airflow from reaching the human body is a key consideration in air conditioner design, particularly for the elderly, children, and the infirm, as such exposure can easily cause discomfort.

[0003] In order to prevent direct blowing, other air ducts will be set on the air conditioner to guide the air flow to be released from a 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, and the limited internal assembly space of the air conditioner, it is inevitable that part of the transmission structure will be located inside the air duct. Inside the air duct, the transmission parts and other moving parts in the transmission structure will be directly exposed to the air flow. 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 part of the transmission structure. As the dust accumulates, the wear between the transmission structures will increase, and even jamming may occur. Utility Model Content

[0004] In order to overcome at least one of the defects described in the above-mentioned prior art, the utility model provides a transmission component dustproof structure, an air guide plate transmission mechanism and an air conditioner, which can solve the dust accumulation problem generated by the transmission components 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 the 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 air 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 provided on the leeward side of the dustproof member;

[0009] In which, 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 over the transmission part body toward the side wall of the dustproof part.

[0010] By adopting the above solution, when airflow encounters the dust shield, secondary flows are formed. These secondary flows create a specific airflow field in the direction from the dust shield toward the transmission body. This specific airflow field forms a cavity and a wake region on the leeward side of the dust shield. The flow velocity in the cavity region is relatively low, and due to air viscosity, the airflow velocity is even lower near the sidewalls of the transmission body, resulting in strong vortices within the cavity region. These vortices interfere with the entry of external airflow and prevent stable airflow within the cavity region. Combined with the Coanda effect, which causes fluids to flow along surfaces, this further hinders airflow from entering the cavity region. Therefore, when the transmission body is located within the cavity region formed by the dust shield, the airflow is less likely to directly impact the transmission body, effectively reducing dust accumulation. Consequently, the design of the dust shield reduces dust interference with the transmission body, ensuring smooth and reliable operation of the transmission over extended periods of time. This not only improves transmission efficiency but also reduces the risk of dust-induced jamming, ensuring the proper 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 exactly 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, by designing the transmission member body to include a transmission arm and a sector-shaped toothed disc, and by fixedly connecting the transmission arm and the sector-shaped toothed disc, the entire transmission member body is positioned on the leeward side of the dust shield. When air flows through the dust shield, since both the transmission arm and the sector-shaped toothed disc are positioned on the leeward side of the dust shield, the secondary flow formed after the airflow passes over the transmission arm and the sector-shaped toothed disc toward the sidewall of the dust shield. This effectively insulates the transmission arm and the sector-shaped toothed disc from dust in the airflow, significantly reducing dust accumulation.

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

[0016] By adopting the above solution, by designing the thickness of the transmission body to be less than or equal to that of the dustproof, the transmission body can be ensured to be completely within the protection range of the dustproof. Due to the smaller thickness of the transmission body, the secondary flow formed after the airflow passes through the dustproof can more easily pass over the transmission body toward the side wall of the dustproof, making the transmission body virtually unaffected by 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 sector gear 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 beneficial to 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 this solution, both the transmission body and the dust shield are crank-connecting rods. This design simplifies the structure and facilitates the installation of other drive components. The standardized crank-connecting rod design simplifies the connection and assembly of various components, reducing installation time and costs and improving production efficiency. This design also facilitates subsequent maintenance and replacement, further improving system reliability.

[0021] The utility model also provides an air deflector transmission mechanism, which adopts the above-mentioned transmission member dust-proof structure, including a driving assembly and a transfer connecting rod, the driving assembly including 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 rotatably connected to the transfer connecting rod, a rotating connecting shaft is provided in the middle of the transmission member body to enable the transmission member body to rotate around the rotating connecting shaft, one end of the dust-proof 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-shaped trajectory. 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 solution and the transmission dust-proof structure, both the transmission body and the dust-proof member in the air deflector transmission mechanism are designed as crank-connecting rods, ensuring that the transmission body remains within the protection range of the dust-proof member during movement. When air flows through the dust-proof member, the resulting secondary flow effectively passes over the transmission body, reducing dust accumulation and providing better protection for key components such as the transmission arm and the sector gear. Furthermore, the transmission body and the dust-proof member cooperate to drive the transfer link to move up and down, forward and backward, thereby achieving forward and upward movement of the panel.

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

[0025] By adopting this solution, the meshing design of the output gear and the sector gear disc ensures a fixed transmission ratio, enabling precise motion control. This helps improve the positioning accuracy of the wind deflector, ensuring accurate adjustment of the wind direction, and further enhancing 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 rod at the other end. The secondary flow formed after the air flow out of the air conditioner passes 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 this solution, multiple dust guards may be required in certain environments, such as large air conditioners. This makes the entire transmission structure more stable. Each dust guard is arranged parallel to the transmission body, with one end pivotally connected to the external carrier and the other to the adapter rod. This design ensures that the transmission components maintain coordinated movement, avoiding excessive wear and failure caused by asynchronous movement, and improving system reliability and stability.

[0028] The utility model also provides an air conditioner, which adopts the above-mentioned air deflector transmission mechanism and includes a middle frame. The air deflector 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 airflow encounters the dust shield, secondary flows form. These secondary flows form a specific airflow field behind the leeward side of the dust shield, that is, in the direction from the dust shield toward the transmission body. This specific airflow field forms a cavity region and a wake region behind the leeward side of the dust shield, which together form six zones, or the confluence of the secondary flows. Due to the lower flow velocity within the cavity region, and the even lower velocity near the sidewalls of the transmission body due to air viscosity, strong vortices form within the cavity region. These vortices interfere with the entry of external airflow and cause the airflow within the cavity region to form a stable backflow within the cavity region. Combined with the Coanda effect, which causes fluids to flow along surfaces, this further hinders external airflow from entering the cavity region. Therefore, when the transmission body is located within the cavity region formed by the dust shield, external secondary flows are less likely to directly impact the transmission body, effectively reducing dust accumulation on the transmission body. Consequently, the design of the dust shield reduces dust interference with the transmission body, ensuring smooth and reliable operation of the transmission over extended periods of time. 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 in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0043] See Figure 1-Figure 7 The utility model discloses a transmission dust-proof structure, which is arranged on the air outlet path of the air conditioner 5, including 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 facing the side of the air outlet direction of 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 flows, 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. 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. 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, secondary flows are formed. These secondary flows form a specific airflow field after passing through the dustproof part 2. This 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 part body 1 is even lower, resulting in the formation of strong vortices 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 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 part body 1, effectively reducing the accumulation of dust. Correspondingly, the design of the dustproof part 2 reduces the interference of dust on the transmission part body 1, 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 5.

[0047] participate Figure 1 and Figure 2 As shown, in some embodiments, the spacing S between the transmission component body 1 and the dustproof component 2 is set, 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 in 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, a too small spacing between the dustproof member 2 and the transmission member body 1 is not conducive to the assembly of other transmission components and stable transmission. If the spacing 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 spacing between the transmission member body 1 and the dustproof member 2 to S = (5 to 20) T, it can be ensured that the transmission member body 1 is exactly located in the cavity area formed by the dustproof member 2, and the instability in the transmission process will not be caused by the spacing between the dustproof member 2 and the transmission member body 1 being too small.

[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, and the fan-shaped toothed disc 12 is used for transmission connection with the 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 dust-proof member 2, so that the secondary flow formed after passing through the dust-proof member 2 passes over the transmission arm 11 toward the side wall of the dust-proof member 2 and the fan-shaped toothed disc 12 toward the side wall of the dust-proof member 2.

[0050] Specifically, by designing the transmission body 1 to include a transmission arm 11 and a sector-shaped toothed disc 12, and by fixedly connecting the transmission arm 11 and the sector-shaped toothed disc 12, the entire transmission body 1 is positioned on the leeward side 22 of the dust guard 2. When airflow passes through the dust guard 2, since both the transmission arm 11 and the sector-shaped toothed disc 12 are positioned on the leeward side 22 of the dust guard 2, the secondary flow formed after the airflow passes over the transmission arm 11 and the sector-shaped toothed disc 12 toward the sidewall of the dust guard 2. This effectively insulates the transmission arm 11 and the sector-shaped toothed disc 12 from dust in the airflow, significantly reducing dust accumulation.

[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 that of the dust guard 2, the transmission body 1 is ensured to be completely within the protective range of the dust guard 2. Due to the smaller thickness of the transmission body 1, the secondary flow formed after the airflow passes through the dust guard 2 can more easily pass over the transmission body 1 toward the side wall of the dust guard 2, making the transmission body 1 virtually unaffected by dust in the airflow. This greatly reduces dust accumulation on the transmission body 1, providing better protection for key components such as the transmission arm 11 and the sector gear disc 12.

[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 conducive to the subsequent installation of other transmission components.

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

[0056] Specifically, both the transmission body 1 and the dust shield 2 are crank-connecting rods. This design simplifies the structure and facilitates the installation of the other drive components 3. The standardized crank-connecting rod design simplifies the connection and assembly of the various components, reducing installation time and costs and improving production efficiency. This design also facilitates subsequent maintenance and replacement, further enhancing system reliability.

[0057] See Figure 3-Figure 6 As shown, the present invention also provides an air deflector transmission mechanism, which adopts the above-mentioned transmission member dustproof structure, including a driving assembly 3 and a transfer link 4. The driving assembly 3 includes a driver 31 and a driving member 32. The driver 31 is transmission-connected to the driving member 32. One end of the transmission member body 1 is transmission-connected to the driving member 32, and the other end is rotationally connected to the transfer link 4. A rotating connecting shaft 13 is provided in the middle of the transmission member body 1 to enable the transmission member body 1 to rotate around the rotating connecting shaft 13. One end of the dustproof member 2 is rotationally connected to an external mounting carrier, and the other end is rotationally connected to the transfer link 4. The transfer link 4 is fixedly connected to a panel 51. The driving member 32 drives the transmission member body 1 to rotate around the rotating connecting shaft 13, so as to drive the transfer link 4 and the panel 51 to move up and down and forward and backward in an arc-shaped trajectory. When the transfer link 4 moves, the transfer link 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 capable of driving 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 device capable of driving the transmission body 1 to rotate around the rotation connecting shaft 13, such as a gear, a telescopic rod, etc., and the specific structure is not limited here. The driver 31 is connected to the driving member 32 in a transmission connection, and the driving member 32 is connected to the transmission member body 1 in a transmission connection. 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, and the transmission member body 1 is rotatably connected to the 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 movement with the transmission member body 1. In addition to reducing dust accumulation for 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 Figure 3-Figure 6 As shown, in some embodiments, the driving member 32 is an output gear, and the output gear is engaged with the sector gear plate 12 .

[0060] Specifically, the meshing design of the output gear and the sector gear disc 12 enables a fixed transmission ratio, enabling precise motion control. This helps improve the positioning accuracy of the air deflector, ensures accurate adjustment of the wind direction, and further enhances the user experience.

[0061] See Figure 3-Figure 6 As shown, in some embodiments, there are multiple dust-proof parts 2, all of which are arranged parallel to 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 part 2 close to the transmission part body 1 passes over the transmission part body 1 toward the side wall of the dust-proof part 2.

[0062] Specifically, in certain environments, such as large air conditioners 5, multiple dust guards 2 may be required. These multiple dust guards 2 further stabilize the entire transmission structure. Each dust guard 2 is arranged parallel to the transmission body 1, with one end pivotally connected to the external carrier and the other to the transfer link 4. This design ensures that the transmission components maintain coordinated motion, avoiding excessive wear and failure caused by asynchronous motion, and improving system reliability and stability.

[0063] See Figure 3-Figure 6 As shown, as an option, a mounting base 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 base 6, the driver 32 is transmission-connected to the driver 31, and the rotating connecting shaft 13 of the transmission body 1 is rotationally mounted on the mounting base 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 engaged with the driver 32. The dustproof member 2 is arranged parallel to the transmission body 1, and one end of the dustproof member 2 is rotationally connected to the mounting base 6, thus completing the structural installation of the mounting base 6. When 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 Figure 3-Figure 6 As shown, the present invention also provides an air conditioner, which adopts the above-mentioned air guide plate transmission mechanism, including a middle frame 52, and the air guide plate transmission mechanism is assembled on the side of the middle frame 52 facing the air outlet, that is, the air guide plate transmission mechanism is assembled on the front of the middle frame 52.

[0065] Optionally, the middle frame 52 of the air conditioner 5 is further 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 part 2 and the transmission part body 1 will be located in the air duct. When the air conditioner 5 releases airflow, the airflow will first pass through the dustproof part 2. The airflow passing through the dustproof part 2 forms a secondary flow. The secondary flow will bypass the dustproof part 2 and continue to flow toward the transmission part body 1. These secondary flows will merge at a distance of S (5 to 20) T. A cavity area is formed between the dustproof part 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 flow velocity of this specific airflow field is relatively low, and due to the influence of air viscosity, the airflow velocity 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, by locating the side wall of the transmission part body 1 facing the dustproof part 2 in the cavity area, the dust in the airflow can be effectively reduced 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 body 1, even if grease is provided on the sector-shaped toothed disc 12 of the transmission body 1, due to the effective protection of the dustproof member 2, only a very small amount of dust will enter the transmission body 1 area, which will not affect the normal operation of the transmission body 1. This ensures the lubrication effect of the transmission body 1 and further extends the service life of the transmission.
