Description

Technical Field

[0001] This invention relates to the field of fan channel structures, and more particularly to a channel structure based on a ceramic heat-conducting fan. Background Technology

[0002] Hair dryers are common household appliances in modern life, used to quickly dry hair and care for it. For added convenience, some hair dryers are designed to be cordless by having a pre-installed battery. To achieve the hot air blowing function, existing hair dryers incorporate a metal heating wire inside the blower's airflow channel. When the user needs it, the heating wire is energized to generate heat, which in turn heats the air flowing through the channel, thus producing hot air. However, the heating wire consumes a lot of energy when heating, which results in a short effective usage time for cordless hair dryers. Increasing the battery capacity to improve the battery life of cordless hair dryers also increases the size and weight of the battery, which in turn increases the size and weight of the cordless hair dryer, making it extremely inconvenient for users. Furthermore, if a large-capacity battery (such as more than 10,000 mAh) experiences a short circuit or other malfunction and discharges, it can cause significant harm to the user. Furthermore, to ensure the stability and heat insulation of the metal heating wire, the bracket that fixes the heating wire contains asbestos (mica sheets). This results in the release of fine asbestos fiber particles from the channel after long-term use. Inhaling these particles can cause significant damage to the lungs. Additionally, the metal wire heating requires the insulation of the conductor. Hair dryers are commonly used in bathrooms, where moisture can easily enter the hair dryer. After long-term use, the insulation component of the metal wire is prone to aging, greatly increasing the risk of electric shock. Furthermore, existing technologies require the drive motor that rotates the fan blades to be placed inside the channel to achieve airflow. This causes the airflow to be blocked by the drive motor itself, preventing the airflow from passing evenly through the metal heating wire. Consequently, the airflow cannot be heated evenly, resulting in uneven heat distribution in the exhaust airflow. On the other hand, after being blocked by the drive motor, the airflow will pass through the local through-holes of the heating wire more quickly. This causes turbulence generated by the friction between the airflow and the heating wire, resulting in periodic vibration of the air column and greatly increasing the noise during equipment operation. Summary of the Invention

[0003] In order to overcome the shortcomings of existing technologies, such as the emission of fine asbestos fiber particles after long-term use, which can cause harm to the human body, the high risk of electric shock, and the high noise of existing technologies, this invention provides a channel structure based on a ceramic heat-conducting fan.

[0004] Technical solution: A channel structure based on a ceramic heat-conducting fan, comprising: The cylinder has a flow channel that allows external media to flow through it, and a drive assembly is provided in the flow channel. An air supply gap is formed between the drive assembly and the inner wall of the cylinder. The feature is that it further includes: a heating component, disposed in the flow channel and near one end of the cylinder output end, the heating component including a heating element, the heating element being provided with a buffer unit for reducing the impact on the heating element when it is subjected to force; The buffer unit is provided with a flow guide, which is located on the side of the heating element close to the driving component. The flow guide is a hollow cylinder with a first opening. The first opening can at least partially cover the air supply gap. Along the medium flow direction, the sidewall of the flow guide is gradually narrowed and converged to form a second opening. The heating element is provided with a through hole, which extends along the medium flow direction of the flow channel, and the heating element is made of ceramic heating components. During operation, the guide element guides the flow medium of the air supply gap to flow in through its first opening and out through its second opening to the heating element; the heating element can heat the flowing medium in the working state, and the buffer unit can cover the side wall of the heating element.

[0005] The beneficial effects of this invention are: by designing and operating the heating element, it avoids the problem of existing technologies emitting fine asbestos fiber particles after long-term use, which could cause harm to the human body. Furthermore, it avoids the problems of existing technologies that rely on metal wire heating, which depends on the conductivity of metal conductors for heat generation. While this results in rapid heating, it is prone to overheating and oxidation, leading to decreased work efficiency with long-term use. At the same time, the ceramic structure of the heating element prevents moisture from entering the hair dryer and corroding the metal wire insulating component, causing it to age and significantly increasing the risk of electric shock. Furthermore, the contact area between the flowing medium and the heating element is larger per unit time, thus the heating efficiency of the flowing medium is higher, the hot air function efficiency of the device is enhanced, and the heating power consumption of the device is reduced. By designing the flow guide, the flowing medium can be heated more evenly, resulting in a more uniform heat distribution in the heating medium discharged from the device. At the same time, it solves the problem of turbulence caused by friction between the flowing medium and the edge of the through hole when the flowing medium is covered, which greatly increases the noise during the operation of the device.

Detailed Implementation

[0010] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0012] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0013] This invention provides a channel structure based on a ceramic heat-conducting fan, such as... Figure 1-17 As shown, it includes: The cylinder 01 is provided with a flow channel that allows external media to flow through it. A drive assembly 2 is provided in the flow channel, and an air supply gap is formed between the drive assembly 2 and the inner wall of the cylinder 01. The feature is that it further includes: a heating component 03, which is disposed in the flow channel and close to the output end b of the cylinder 01. The heating component 03 includes a heating element 5, and the heating element 5 is provided with a buffer unit 51 for reducing the impact on the heating element 5 when it is subjected to force. The buffer unit 51 is provided with a flow guide 75, which is located on the side of the heating component 5 near the driving component 2. The flow guide 75 is a hollow cylinder with a first opening. The first opening can at least partially cover the air supply gap. Along the medium flow direction, the side wall of the flow guide 75 is gradually contracted and gathered to form a second opening. The heating element 5 is provided with a through hole, which extends along the medium flow direction of the flow channel, and the heating element 5 is made of ceramic heating components. During operation, the guide member 75 guides the flow medium of the air supply gap to flow in from its first opening and out from its second opening to the heating member 5; the heating member 5 can heat the flowing medium in the working state, and the buffer unit can cover the side wall of the heating member 5.

[0014] Before operation, the heating component 03 and the drive component 02 are electrically connected to a preset power source (such as a battery or power interface). At this time, the heating component 03 begins heating, and the drive component 02 begins driving. The drive component 02 introduces the external flowing medium from the input end a into the flow channel of the cylinder 01. When the flowing medium flows through the flow channel, it passes through the heating component 03. At this time, the flowing medium absorbs the heat emitted by the heating component 03 and forms a heating medium. Then the heating medium passes through the heating component 03 and is discharged from the output end b, thus realizing the hot air function of this device. However, in practical applications, existing technologies use metal heating wires inside the hairdryer's cooling channel to achieve the hot air function. But the brackets that hold the heating wire in place contain asbestos (mica sheets) to ensure the stability and insulation of the metal heating wire. Over time, this releases fine asbestos fiber particles, which can be harmful to human health. Therefore, the heating component 03 includes a heating element 5, which is made of ceramic heating element and has several through holes that allow the flow of fluid. The heating element 5 is connected to a preset power source through a heating electrical device. Specifically, when the flowing medium flows through the circulation channel, it passes through the through hole of the heating element 5 to form a heating medium. During this process, the contact area between the flowing medium and the heating element 5 is larger per unit time, so the heating efficiency of the device is higher, which enhances the hot air function efficiency of the device and reduces the heating power consumption of the device. Furthermore, the heating element 5 is made of ceramic heating components and is connected to the circulation channel of the cylinder 01. This avoids the problem that existing technologies contain asbestos (mica sheet support) inside and emit fine asbestos fiber particles, which may cause harm to the human body. Furthermore, the heating element 5 is specifically a heating ceramic body formed by dry pressing conductive ceramic powder. Its resistance is adjustable, its heating speed is fast, its resistance is uniform, its heating is even, its efficiency is high, and its energy consumption is low. Moreover, the instantaneous temperature of the heating element 5 can reach over 300°C, enabling it to quickly generate sufficient heat. Therefore, it can ensure that the air outlet of the hair dryer has sufficient temperature for operation while maintaining low energy consumption and low power, and it also has a long battery life. Thus, when this device is actually used in conjunction with a wireless battery, with a fixed battery capacity, the heating element 5 consumes less energy than the heating wire used in existing technology, and its effective heating time is greatly improved. This avoids the problems of existing technologies that use heating wires for heating, which consume a lot of energy and have a short effective usage time. Increasing the battery capacity to improve the battery life of a cordless hair dryer also requires increasing the size and weight of the battery, which makes the cordless hair dryer larger and heavier, making it inconvenient for users. Furthermore, if a large-capacity battery experiences a short circuit or other malfunction and discharges, it can cause serious harm to the user. Furthermore, in actual use, this device is installed on a hair dryer, which is typically used in the confined space of a bathroom or placed beside the bed after use in a bedroom. In these scenarios, the hair dryer is highly susceptible to collisions with the surrounding walls or floor (such as falling from a bedside table). The heating element 5 is made of ceramic, which is extremely prone to cracking or even shattering upon impact. Therefore, to ensure the stable use of this device, a buffer unit 51 is also provided. The buffer unit 51 can cover the side wall of the heating element 5. When the hair dryer is bumped, and the heating element 5 is impacted by the cylinder 01, the buffer unit 51 can deform to reduce the impact on the heating element 5 when it is subjected to force. This can avoid the problem that the heating element 5 is prone to cracking or even breaking when the hair dryer is bumped. Furthermore, since the drive assembly 02 is located within the flow channel of the cylinder 01, the drive assembly 02 itself will obstruct the flow of the medium within the flow channel. This prevents the flow of the medium from passing evenly through the through holes of the heating element 5. On the one hand, this will cause the flowing medium to be heated unevenly, resulting in uneven heat distribution of the heating medium discharged by the device. On the other hand, after the flowing medium is covered, it will pass through the local through hole of the heating element 5 more quickly, which will cause the flowing medium to rub against the edge of the through hole to generate turbulence, causing the air column to vibrate periodically, which greatly increases the noise when the device is working. Therefore, the second buffer component 7 is equipped with a drainage element 75, such as Figure 6 As shown, when the flowing medium flows within the flow channel of the cylinder 01 and passes through the guide member 75, because the guide member 75 partially covers the air supply gap between the drive assembly 2 and the inner wall of the cylinder 01, the guide member 75 can guide the flowing medium in the air supply gap to flow in from the first opening and out from the second opening to the heating element 5. The guide element 75 guides the flowing medium, causing a portion of it to flow into the covered through-hole of the heating element 5, thereby achieving uniform heating of the flowing medium and reducing noise generated during operation. Example 2 Based on the above embodiment 1, as follows Figure 3 As shown, Preferably, it further includes: An air outlet cover 04 is disposed at the output end b of the cylinder 01. Extending along the second direction y, the air outlet cover 04 protrudes from the cylinder 01. An air inlet cover 05 is disposed at the input end a of the cylinder 01, extending along the second direction y, and the air inlet cover 05 protrudes from the cylinder 01; The air inlet cover 05 and the air outlet cover 04 can prevent foreign objects from entering the flow channel of the cylinder 01.

[0015] The flowing medium enters the cylinder 01 flow channel from input end a and then exits from output end b. Since this device is primarily used in bathrooms and similar environments... In actual use, this device blows out the user's hair, which then scatters in the air. When the device is used, this hair mixes with the flowing medium and enters the circulation channel of cylinder 01, becoming stuck inside. The hair also gets stuck in the through-hole of heating element 5, preventing the flowing medium from passing through it normally, significantly affecting the normal operation of the device. Therefore, this device also includes an air inlet cover 05, which is disposed at the output end b of the cylinder 01 to filter impurities flowing into the flowing medium from the input end a. Furthermore, the device is also equipped with an air outlet cover 04, which can prevent foreign objects from extending into the flow channel of the cylinder 01 from the output end b.

[0016] Example 3 Based on the above embodiment 1, as follows Figures 3-4 As shown, Preferably, the driving component 02 includes: Mounting bracket 2, connected to the flow channel of the cylinder 01, allows the flow medium to pass through; A drive component 1 is connected to the mounting bracket 2, with its working end facing the output end b. The working end of the drive component 1 is equipped with a flap wheel 3 for introducing the flowing medium into the flow channel. A shock absorber 4 is disposed within the flow channel of the cylinder 01. The shock absorber 4 has a through channel for allowing the flow medium to pass through. The flap wheel 3 is located within the through channel of the shock absorber 4. There is a shock-absorbing gap between the shock absorber 4 and the inner wall of the cylinder 01. Several shock absorbers 41 are arranged around the shock absorber 4 within the shock-absorbing gap. The shock absorbers 41 are interference-fitted and are made of flexible deformable material.

[0017] The specific function of the drive assembly 02 is that, through the operation of the drive component 1, the connected flap wheel 3 starts to rotate. When the flap wheel 3 rotates, the flowing medium can be introduced from the input end a into the flow channel of the cylinder 01. However, the flap wheel 3 will generate a certain amount of vibration during actual operation. This vibration is transmitted to the cylinder 01, and then to the user's limbs, which greatly reduces the user experience. Therefore, the drive assembly 02 is also equipped with a shock absorber 4. The flap wheel 3 is located in the through channel of the shock absorber 4. When the flap wheel 3 vibrates during operation, the vibration will be transmitted to the shock absorber 4 first. Several shock absorbers 41 are provided on the outer wall of the shock absorber 4. The shock absorbers 41 are also interference-fitted with the cylinder body 01. In this way, the shock absorbers 41 can greatly reduce the vibration generated by the flap wheel 3 during operation, thereby greatly improving the user experience.

[0018] Example 4 Based on the above embodiment 1, as follows Figures 3-6 As shown, Preferably, the buffer unit 51 includes a first buffer component 6 and a second buffer component 7; The first buffer component 6 and the second buffer component 7 are respectively disposed on both sides of the heating component 5, and the first buffer component 6 is disposed on the side of the driving component 02 away from the input end a; The first buffer assembly 6 includes: a first cover 61, a first cover sheet 611, a first connecting piece 62, and at least one first elastic member 64; The first connecting piece 62 is connected to the inner wall of the cylinder 01. One end of the first elastic member 64 is connected to the side of the first connecting piece 62 near the input end a; The first cover 61 is connected to the other end of all the first elastic members 64, and the first cover 61 is in contact with the heating member 5. The first cover 61 is provided with the first covering sheet 611, which extends along the first direction x toward the heating member 5 to cover the side wall of the heating member 5, and the first covering sheet 611 is in contact with the inner side wall of the cylinder 01. The second buffer assembly 7 includes: a second connecting piece 71, a second covering 72, a second covering piece 721, and at least one second elastic member 73; The second connecting piece 71 is connected to the inner wall of the cylinder 01. The second elastic element 73 is connected to the second connecting piece 71 on the side near the output end b; The second cover 72 is connected to the second elastic member 73, and the second cover 72 is located on the side near the output end b. The second cover 72 is provided with a second covering piece 721, which extends along the first direction x toward the heating member 5 to cover the side wall of the heating member 5, and the second covering piece 721 is interference-fitted with the inner side wall of the cylinder 01.

[0019] Specifically, to prevent the heating element 5 from cracking or even breaking when it is bumped, this device is equipped with a first buffer assembly 6 and a second buffer assembly 7. Furthermore, to further ensure that the first buffer assembly 6 and the second buffer assembly 7 can reduce the impact on the heating element 5 when subjected to force, the first buffer assembly 6 is provided with a first elastic element 64, and the second buffer assembly 7 is provided with a second elastic element 73. Due to the arrangement of the first elastic element 64 and the second elastic element 73, when the heating element 5 is subjected to an axial impact force, it can move axially and compress the first cover 61 or the second cover 72 at the corresponding position. The force is transmitted and also compresses the first elastic element 64 or the second elastic element 73 at the corresponding position. The corresponding first elastic element 64 or second elastic element 73 will also generate a reset force. When the impact force on the heating element 5 disappears, the corresponding first elastic element 64 or second elastic element 73 will release the reset force, thereby pushing the heating element 5 to reset. When the heating element 5 is subjected to radial impact force, the first covering piece 611 and the second covering piece 721 work together to completely cover the side wall of the heating element 5. The first covering piece 611 and the second covering piece 721 are made of flexible material (the flexible material maintains its structural integrity for at least 2000 hours at 380℃-400℃). In this way, the first covering piece 611 and the second covering piece 721 can reduce the radial impact force on the heating element 5, thus avoiding cracks or even breakage of the heating element 5 when it is bumped. When the flowing medium passes through the heating element 5, it exerts a pushing force on the heating element 5. The heating element 5 then moves towards the output end b, pushing the first cover 61 it contacts until it reaches a preset position. During this movement, the first cover 61 exerts a force on the connected first elastic element 64. The first elastic element 64 is compressed, generating a restoring force. This restoring force balances the pushing force exerted by the flowing medium on the heating element 5. When the driving component 1 stops working, the first elastic component 64 releases the reset force, and the heating component 5 can then be reset. In this way, when the heating element 5 is actually used in this device, there will be no problem of the flowing medium disturbing the stability of the heating element 5, which makes the structure of this device more stable during use and further avoids the problem of uneven flow of the flowing medium caused by disturbance.

[0020] Example 5 Based on the above embodiment 1, as follows Figures 3-11 As shown, Preferably, the air outlet cover 04 includes: a connecting cylinder 8 and an intercepting component 9; The connecting cylinder 8 is connected to the output end b of the cylinder 01, and the connecting cylinder 8 has an output slot that allows the flowing medium to pass through. The interception component 9 is connected to the output slot of the air outlet cover 04 to prevent foreign objects from extending into the flow channel of the cylinder 01 from the output end b. The interception component 9 includes: a bracket 91, an interceptor 92, and a mounting strip 93; The mounting strip 93 is connected to the output slot of the connecting cylinder 8. The mounting strip 93 is a hollow structure with one end open, and the open end faces the output end b. The bracket 91 is connected to the outlet slot of the air outlet cover 04, and the bracket 91 is provided with a mounting post extending radially along the air outlet cover 04. The interceptor 92 is connected at one end to the mounting post and at the other end to the mounting strip 93. Furthermore, the interceptor 92 includes a plurality of interceptor plates 921, and the plurality of interceptor plates 921 are radially and uniformly distributed along the circumference of the mounting column of the bracket 91. The interceptor plate 921 is provided with a rotating shaft 9211, one end of which is rotatably connected to the bracket 91, and the other end is rotatably connected to the mounting strip 93 via a torque member. Furthermore, the rotating shaft 9211 extends radially away from the center of the mounting strip 93 from the first direction x-angle and protrudes out of the hollow cavity of the mounting strip 93. A protrusion 922 is provided on one end of the rotating shaft 9211 near the mounting strip 93. The first buffer assembly 6 further includes a pushing component, which is disposed on the first connecting piece 62; When the pushing component is in operation, it can drive the interceptor 92 to unfold, and the unfolded interceptor 92 can allow the flowing medium to flow smoothly out from the output end of the cylinder 01.

[0021] Preferably, the pushing component includes a sliding piece 63, a limiting member 631, and a sliding strip 632; At least one of the sliding bars 632 is connected at one end to the first cover 61, and the other end of the sliding bar 632 extends along the first direction x and passes through the first connecting piece 62. The sliding piece 63 is connected to all the sliding bars 632, and the sliding piece 63 is located on the side of the first connecting piece 62 closer to the output end b; A plurality of the limiting members 631 are connected to the side of the sliding piece 63 near the output end b, and the number of the limiting members 631 corresponds to the number of the intercepting pieces 921.

[0022] In standby mode, since this device is typically used in bathrooms where humidity is high, moisture, dust, and other impurities may enter the flow channel of the device's cylinder 01. Therefore, in the standby state of this device, the interceptor 92 appears as follows: Figure 7 When the device is in a closed state, several interceptors 92 can further prevent foreign objects from extending into the flow channel of the cylinder 01 from the output end b, and prevent impurities from entering the device. When the device starts working, the flowing medium passes through the heating element 5, which pushes the first package cover 61 to move. The first package cover 61 drives the connected sliding strip 632 to slide, and the sliding strip 632 drives the sliding plate 63 to move. When the sliding plate 63 moves, its limiting element 631 moves synchronously. Figure 11 As shown, during the movement of the limiting member 631, it pushes the protrusion 922 provided on the corresponding position of the intercepting plate 921, and the intercepting plate 921 begins to rotate under the force. Figure 11 The interceptor plate 921 is in its deployed state, and at this time, the torque component connected to the interceptor plate 921 begins to generate reset torque. However, since the heating component 5 is also subjected to the driving force of the flowing medium, the interceptor plate 921 can only remain in its deployed state when the device is in operation, thus ensuring the normal operation of the device. When the device stops working, the heating element 5 loses the driving force of the flowing medium and resets, and then the torque element connected to the intercepting plate 921 releases the reset torque, so that the intercepting plate 921 resets. This allows impurities to be blocked from entering the flow channel of cylinder 01 from the output end b, thus achieving initial blocking.

[0023] Example 6 Based on the above embodiment 1, as follows Figures 12-17 As shown, Preferably, the air inlet cover 05 includes a cover 10 and a filter cover 11; the second buffer assembly 7 also includes a sliding rod 74; The filter cover 11 is connected to the input end a of the cylinder 01, and the cover 10 has an input slot that allows the flowing medium to pass through. The cover 10 extends along the second direction y and protrudes from the cylinder 01. The cover 10 is disposed within the input slot of the filter cover 11, and along the first direction (x-angle), the cover 10 is provided with a plurality of blocking slots, and the number of blocking slots corresponds to the number of filter slots provided in the filter sheet 111. Furthermore, along the first direction x-angle, the plurality of shielding grooves and the plurality of filter grooves are staggered so that the cover 10 can block the external flowing medium from entering the flow channel of the cylinder 01 from the input end a. At least one of the sliding rods 74 is connected at one end to the second cover 72, and the other end of the sliding rod 74 extends along the first direction x toward the output end b and passes through the shock-absorbing gap between the shock-absorbing cylinder 4 and the cylinder body 01, and the other end of the sliding rod 74 contacts the cover 10.

[0024] When the drive assembly 02 is in standby mode, the sliding rod 74 can cooperate with the filter cover 11 to limit the cover 10 so that the cover 10 can block the flowing medium entering from the input end a from flowing into the flow channel of the cylinder 01. When the drive assembly 02 is in operation, the cover 10 allows the flowing medium to enter the flow channel of the cylinder 01 from the input end a.

[0025] Preferably, the filter cover 11 includes a filter sheet 111, a mounting part 1111, a telescopic member 112, a limiting cover 113, and a limiting strip 1131; The mounting part 1111 is detachably connected to the input end a of the cylinder 01; the mounting part 1111 is provided with a filter sheet 111; the filter sheet 111 is provided with a plurality of filter grooves, and the filter grooves penetrate the filter sheet 111 along the first direction x. The telescopic member 112 is connected to the filter sheet 111, and the telescopic part of the telescopic member 112 extends toward the cover member 10 and passes through the cover member 10. The cover member 10 is connected to the telescopic part of the telescopic member 112, and the telescopic part of the telescopic member 112 protrudes from the cover member 10 along the second direction y-view. The limiting cover 113 is fixedly connected to the telescopic part of the telescopic member 112, and the limiting cover 113 is provided with a limiting part extending toward the telescopic member 112; At least one of the limiting strips 1131 is fixedly connected at one end to the flap wheel 3, and the other end of the limiting strip 1131 extends toward the limiting cover 113 and is provided with a curved portion; and along the second direction y, the curved portion of the limiting strip 1131 extends toward the middle of the limiting cover 113 and contacts the limiting cover 113.

[0026] In practical operation, impurities can enter the flow channel of cylinder 01 not only from the output end b, but also from the input end a. Therefore, to further prevent impurities from entering, this device is also equipped with a cover 10 and a filter cover 11. When this device is in standby mode, such as Figure 16As shown, the cover 10 and the filter cover 11 are in a close contact state; specifically, the cover 10 and the filter sheet 111 are in close contact. This prevents the flowing medium from entering the flow channel of the cylinder 01 from the input end a. Therefore, in the standby state of this device, both the input end a and the output end b of the cylinder 01 are blocked, and consequently, external impurities cannot enter the flow channel of the cylinder 01 in the standby state. Furthermore, during operation of this device, the flap wheel 3 begins to rotate. As the flap wheel 3 rotates, it drives the connected limiting strip 1131 to rotate as well. When the limiting strip 1131 rotates, it presses against the limiting portion of the limiting cover 113. At this time, the limiting cover 113, constrained and pressed by the limiting strip 1131, begins to move towards the flap wheel 3. Once the limiting cover 113 has moved to a preset position, the limiting portion of the limiting cover 113 disengages from the limiting strip 1131. Thus, the limiting cover 113 no longer affects the rotation of the flap wheel 3 through the limiting strip 1131. Furthermore, during the movement of the limiting cover 113, it will pull the telescopic part of the connected telescopic component 112 to move. When the telescopic part of the telescopic component 112 moves, it will drive the connected cover 10 to move. At this time, if Figure 17 As shown, the cover 10 creates a flow gap with the filter 111. At this time, the external flowing medium, under the operation of the flap wheel 3, can sequentially pass through the filter groove of the filter 111, the flow gap, and the blocking groove of the cover 10, entering the flow channel of the cylinder 01. Furthermore, when the cover 10 moves, it presses against the contacting sliding rod 74, causing the sliding rod 74 to move towards the input end a. At this time, the sliding rod 74 pushes the second cover 72 to move. Since the second cover piece 721 of the second cover 72 is interference-fitted with the inner wall of the cylinder 01, the elastic force of the second elastic member 73 is insufficient to pull the second cover 72 back to its original position. Thus, the sliding rod 74 cannot return to its original position during the operation of this device. In this way, the cover 10 can maintain a flow gap with the filter 111, and the flow gap can continuously enter the flow channel of the cylinder 01 from the inlet a. When the device stops working, the heating element 5 will reset under the action of the first elastic element 64. At this time, the resetting force of the heating element 5 will act on the second cover 72. Thus, the second cover 72 is also pulled by the resetting force of the second elastic element 73. At this time, the second cover 72 will begin to move and reset, and the sliding rod 74 will also move and reset. When the sliding rod 74 is reset, it will push the cover 10 to reset and move. The cover 10 will then drive the telescopic part of the telescopic part 112 to reset and retract. When the telescopic part of the telescopic part 112 retracts, the limiting part of the limiting cover 113 will exert a limiting force on the limiting strip 1131 in the opposite direction (the leaf wheel 3 can rotate with the limiting strip 1131). In this way, the limiting strip 1131 will be re-engaged into the recess of the limiting cover 113.

[0027] Example 7 Based on the above embodiment 1, as follows Figures 12-17 As shown, Preferably, the covering member 10 includes a cover plate 101 and a guide portion 102; The shield 101 is rotatably connected to the telescopic part of the telescopic member 112 and abuts against the filter 111. The sliding rod 74 contacts the shield 101, and a plurality of shielding grooves are provided on the shield 101. The shield 101 and the mounting part 1111 are in clearance fit. A plurality of guide portions 102 are disposed on the shield 101, and the guide portions 102 extend obliquely toward the output end b of the cylinder 01, and the guide portions 102 are provided with toothed grooves, and the guide portions 102 are made of magnetic material; The filter 111 is provided with at least one magnetic part 111a, which is located on one side of the guide part 102 at the corresponding position.

[0028] This device is commonly used in bathrooms. Since the flowing medium enters the output end b through the air inlet cover 05, any hair shed by the user will be drawn into the device by the flowing medium through the air inlet cover 05. Current technology uses a conventional grid cover for the output end b, which provides very little actual protection, allowing a significant amount of hair to still enter. Therefore, the cover 10 of this device includes a cover plate 101 and a guide portion 102. When the cover 10 is moved by the telescopic part of the telescopic member 112, specifically, the cover plate 101 moves, and the cover plate 101 drives the guide portion 102 to move. When a flow gap is created between the baffle 101 and the filter 111, the flowing medium passes through the baffle groove and simultaneously through the guide portion 102. At this time, the flowing medium drives the baffle 101 to rotate through the guide portions 102, and the guide portions 102 also rotate simultaneously. As the guide portions 102 rotate, their toothed grooves can hook any loose hair passing through the baffle groove, thus preventing hair from entering the device from the output end b. Furthermore, when this device stops working, since the guide portion 102 loses the driving force of the flowing medium, the baffle 101 will also stop rotating. Because the guide portion 102 is made of a magnetic material, and the filter element 111 is provided with a magnetic part 111a, under the magnetic force of the magnetic part 111a, the magnetic part 111a will attract the filter element. After the filter element 111 stops rotating, the nearest guide portion 102 will be attracted to it. Figure 14 As shown, the magnetic part 111a is disposed in front of the filter groove of two adjacent filter plates 111, so that the shield 101 can still block the filter groove of the filter plate 111 after it stops rotating.

[0029] Example 8 Based on the above embodiment 1, as follows Figures 14-17 As shown, Preferably, the filter cover 11 further includes an installation cylinder 1121 and a protective cover 1122; The mounting cylinder 1121 is connected to the filter element 111, and the mounting cylinder 1121 extends through the filter element 111. One end of the telescopic member 112 is connected to the mounting cylinder 1121, and the mounting cylinder 1121 has a through hole. The connection end between the telescopic component 112 and the mounting cylinder 1121 is open, and the opening of the telescopic component 112 communicates with the through hole of the mounting cylinder 1121. The protective cover 1122 is detachably connected to the mounting cylinder 1121, and the protective cover 1122 can cover the through hole of the mounting cylinder 1121.

[0030] Furthermore, if the guide section 102 is not cleaned after collecting hair for a long time, the accumulated hair will clog the blocking groove of the filter 101. Therefore, the filter cover 11 also includes a mounting cylinder 1121 and a protective cover 1122. When the user needs to clean the hair collected inside the device, the user can remove the protective cover 1122, and then push the opening at the connection end of the telescopic member 112 with the mounting cylinder 1121 through the through hole. At this time, the telescopic part of the telescopic member 112 can move further towards the flap wheel 3. At this time, the telescopic part of the telescopic member 112 drives the connecting limit cover 113 to disengage from the limit strip 1131. Then, remove the mounting part 1111 from the cylinder 01, and apply lateral force to the mounting part 1111 to remove the entire air inlet cover 05 from the device. This allows for quick and easy cleaning of the hair on the guide part 102.
