Description

Technical Field

[0001] This utility model relates to the field of fluid regulation components, and in particular to a vector control hair dryer assembly and device thereof. Background Technology

[0002] Hair dryers, as common personal care and industrial electrical appliances, function primarily by using a motor-driven fan to generate airflow, which is then heated by a heating element and discharged through the outlet to dry and shape objects. Traditional hair dryers typically use a fixed-diameter round or flat outlet design, resulting in significant limitations in terms of functional expansion and usage flexibility.

[0003] Currently, the wind speed adjustment of commercially available hair dryers mainly relies on the linear adjustment of motor power, that is, adjusting the fan speed by changing the supply voltage or current. This adjustment method has the following technical defects: (1) When a lower wind speed is required, the motor works in a non-optimal energy efficiency range for a long time, resulting in a significant increase in energy consumption; (2) When running at high speed, the airflow channel cross section is fixed, which easily generates turbulence and causes abnormal noise; (3) It is difficult to achieve fine control of airflow characteristics by simply relying on power adjustment, such as the lack of independent adjustment capability for key parameters such as wind pressure and airflow concentration.

[0004] In terms of air outlet shape adjustment, existing technologies generally use detachable nozzle accessories to achieve airflow guidance function, and users need to manually replace different shaped air guide covers to meet the styling requirements. Such solutions have obvious pain points: (1) the accessory replacement process is cumbersome, affecting the continuity of operation; (2) accessories are easy to be lost or damaged during storage; (3) discrete accessory combinations make it difficult to achieve continuous and gradual adjustment of air outlet parameters, limiting the diversity of styling effects.

[0005] In addition, the fixed air outlet design means that the contact area between the airflow and the air receiving surface is not adjustable. When performing special styling (such as partial styling, curling, etc.), users often need to frequently change the distance or angle of the hair dryer, which not only increases the complexity of operation, but also easily leads to the risk of heat damage due to improper distance control.

[0006] Therefore, there is an urgent need to develop a hair dryer air outlet system with dynamic adjustment capabilities. Through structural innovation, the size and shape of the air outlet can be continuously adjusted, thereby breaking through the technical bottleneck of traditional adjustment methods and improving equipment energy efficiency and user experience. Utility Model Content

[0007] The technical problem this invention aims to solve is that traditional hair dryers typically use a fixed-diameter circular or flat design for their air outlets, resulting in significant limitations in terms of functional expandability and operational flexibility. To address these shortcomings of the prior art, this invention provides a vector-controlled hair dryer assembly and device.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0009] A vector-controlled hair dryer assembly is constructed, including a fixed plate and a blade assembly disposed on the fixed plate. The blade assembly forms a closed loop, with a second fluid inlet at one end of the blade assembly having a constant area, and a second fluid outlet at the other end. A second fluid channel is formed between the second fluid inlet and the second fluid outlet. Fluid enters the second fluid channel through the second fluid inlet and exits from the second fluid outlet. The fluid adjustment assembly is characterized by further including an adjustment component connected to the blade assembly. The adjustment component changes the size of the second fluid outlet, causing a change in the area or shape of the second fluid outlet to alter the physical parameters and / or behavior patterns of the fluid passing through the second fluid outlet.

[0010] Preferably, the side of the blade assembly connected to the fixed disk is the fixed end, and the other side of the blade assembly is the adjusting end. The adjusting component rotates to change the shape of the adjusting end, thereby changing the area or shape of the second fluid outlet.

[0011] Preferably, the adjustment assembly includes an adjustment disk, the rotation of which causes the adjustment end of the blade assembly to move to change the area of ​​the second fluid outlet;

[0012] The adjustment end action includes closing or opening the adjustment end to change the area of ​​the second fluid outlet;

[0013] Alternatively, the adjustment end can be moved to change the area of ​​the second fluid outlet.

[0014] Preferably, the adjusting disc is connected to the blade assembly via multiple sets of connecting rod assemblies. The rotation of the adjusting disc drives the connecting rod assembly to rotate and causes the adjusting end of the blade assembly to close or open to change the area of ​​the second fluid outlet.

[0015] Preferably, the linkage assembly includes a connecting frame connected to the adjusting disc and the blade group, and a connecting rod connecting the two connecting frames. The connecting frame can rotate relative to the adjusting disc and the blade group, and the connecting rod can rotate relative to the connecting frame. The rotation of the adjusting disc drives the linkage assembly to rotate, and the linkage assembly applies a pulling force to the blade group to make the adjusting end close or open.

[0016] Preferably, the adjusting disc moves up and down to apply a cohesive force to the blade assembly, causing the adjusting end to close and changing the area of ​​the second fluid outlet. After the adjusting disc moves to release the cohesive force on the blade assembly, the blade assembly recovers its deformation, causing the adjusting end to open and changing the area of ​​the second fluid outlet. The radius of the adjusting disc is smaller than the radius of the blade assembly when it is not under force.

[0017] Preferably, the blade assembly is a nozzle, the upper part of the nozzle is conical, and a gap is left between the outer wall of the nozzle and the inner wall of the adjusting plate to form a second fluid outlet. The rotation of the adjusting plate drives the nozzle to move up and down, thereby increasing the area of ​​the second fluid outlet. An elastic element is provided at the lower end of the nozzle. When the nozzle moves downward, the elastic element is compressed. When the adjusting plate rotates without applying a thrust to the nozzle, the deformation of the elastic element recovers, pushing the nozzle to move up and down, thereby reducing the area of ​​the second fluid outlet.

[0018] Preferably, the lower end of the adjusting plate is provided with a pressing column, and the middle part of the nozzle is provided with a receiving cavity corresponding to the pressing column. The receiving cavity is provided with a force-bearing surface, which is inclined. The adjustment plate rotates to make the pressing column contact different force-bearing surfaces, thereby causing the nozzle to move downward to increase the area of ​​the second fluid outlet.

[0019] Preferably, the adjusting disc is connected to the blade assembly via a chain rod. The rotation or up-and-down movement of the adjusting disc drives the chain rod to move and applies a closing or opening force to the adjusting end, thereby changing the area of ​​the second fluid outlet.

[0020] Preferably, the adjusting disk is provided with multiple sets of different ribs, and the blade group is provided with protruding posts corresponding to the ribs on the outside. When the adjusting disk rotates, the protruding posts contact different ribs to close the blades and reduce the area of ​​the second fluid outlet. The fixed end of the blade group is provided with an elastic element. When the adjusting end of the blade group is closed, the elastic element is stretched by force. When the ribs do not generate thrust on the protruding posts, the elastic element deforms and pulls the blade group to open the adjusting end and increase the area of ​​the second fluid outlet.

[0021] Preferably, the blade group is formed by multiple sets of blades. The lower ends of the multiple sets of blades are fixedly connected to the fixed disk, and the upper ends are movably connected to the adjustment component and the area of ​​the movable end is changed under the action of the adjustment component. The adjustment component is also provided with a stroke groove, which limits the adjustment range of the second fluid outlet. The adjustment component is also provided with a gear component, and the gear adjustment is felt through the gear component when the adjustment component rotates.

[0022] Preferably, there is a partial overlap between two adjacent sets of blades, and the moving end of the blade changes the area or shape of the overlapping part, so that the fluid passing through the second fluid outlet is spiral or straight.

[0023] Alternatively, the blade may include multiple sets of outer blades and multiple sets of inner blades, with the multiple sets of outer blades forming a closed loop and the multiple sets of inner blades forming a closed loop. The inner blades are placed inside the outer blades, and the connection between two adjacent sets of inner blades is located in the middle of the outer blades.

[0024] A device is constructed, comprising a housing, and a heating module and a driving module disposed within the housing. A first fluid channel is formed within the housing, with a first fluid inlet on one side and a first fluid outlet on the other side. The heating module is positioned between the driving module and the first fluid outlet. The device is characterized in that: a vector-controlled blower assembly as described above is disposed at the first fluid outlet; the first fluid outlet is connected to a second fluid inlet; the driving assembly draws fluid from the first inlet into the first fluid channel, and through the first fluid outlet into the second fluid inlet, and then discharges it through the second fluid outlet within the second fluid channel.

[0025] Preferably, the housing is also provided with a handle, which is arranged perpendicularly or parallel to the first fluid channel. An isolation net is provided at the first fluid inlet, and an air outlet net is provided at the air outlet assembly. The fluid coming out of the second fluid outlet passes through the air outlet net for operation. The angle between the first fluid channel and the second fluid channel is 75°-180°.

[0026] The beneficial effects of this invention are as follows: By setting an air outlet component at the first air outlet, the size and shape of the second air outlet are changed, thereby altering the physical parameters and behavior patterns of the fluid passing through the second air outlet. By rotating or pulling the adjusting disc to reduce the area of ​​the second air outlet, a higher wind speed is achieved at the same power, reducing energy consumption while increasing wind speed and volume, and reducing noise. Simultaneously, by adjusting the size of the second air outlet according to the blade arrangement, the blade arrangement is changed, thereby altering the shape of the fluid passing through the second air outlet. The air outlet shape can be changed without replacing parts, making operation more convenient, improving functional expandability, and increasing flexibility in use. The blades can be closed or opened by rotating the adjustment disc, or different thrusts can be applied to the blades by pulling the adjustment disc up and down to close or open the blades, or the nozzle can be moved up and down by rotating the adjustment disc to increase or decrease the distance between the nozzle and the inner wall of the adjustment disc, or the blades can be pulled up and down by pulling the adjustment disc to apply tension or thrust; or the blades can be pushed by rotating the adjustment disc at different positions to change the size of the second air outlet, thereby changing the physical parameters and behavior patterns of the fluid passing through the second air outlet.

[0071] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0072] The preferred embodiment of this utility model discloses a vector-controlled hair dryer assembly and device. The fluid regulating assembly is used to regulate the flow rate, flow rate, and shape of the fluid. The device generates the fluid; for example, it can be a hair dryer, a hairdryer, or other fluid-generating device. By installing the fluid regulating assembly at the air outlet of the device, the fluid generated by the device can be regulated. This includes regulating the fluid flow rate, the flow volume, or adjusting the fluid's shape (vertical or spiral airflow), collectively referred to as the fluid's flow characteristics. These characteristics encompass the fluid's physical parameters and behavioral patterns. The fluid regulating assembly adjusts the flow characteristics of the fluid generated by the device. While a hair dryer is specifically described as the device in this utility model, other related devices capable of generating fluid flow characteristics also fall within the scope of this utility model. Any device that adjusts the fluid flow characteristics using the fluid regulating assembly and is then used to dry hair or other objects requiring drying can utilize the device of this utility model.

[0073] Specifically, such as Figures 1-3As shown, the hair dryer includes a housing 10, which is T-shaped and detachably connected by a left housing 101 and a right housing 102. The lower part of the housing forms a handle 100 for gripping, and the upper part forms a first fluid channel 103. A first air inlet 104 is formed on one side of the first fluid channel, and a first air outlet 105 is formed at the other end. A rear cover 50 is provided at the first air inlet, connecting one end of the left and right housings. The rear cover has multiple sets of isolation holes communicating with the first air inlet, allowing fluid to enter the first fluid channel 103. The isolation holes also prevent larger particulate impurities from entering the first fluid channel. A motor 20, a control board 30 connected to the motor, and a heating module 40 connected to the control board are also located in the upper part of the housing 10. The other ends of the left and right housings are connected by a front locking ring 70, which houses an air outlet mesh 80. The air outlet mesh also has multiple sets of isolation holes to prevent particulate matter from entering the first fluid channel. The heating module 40 is located near the first air outlet 105, between the motor 20 and the first air outlet. The motor creates fluid in the first fluid channel, which enters through the first air outlet 104 and exits through it. The heating module heats the fluid as it passes through, allowing it to be discharged from the first air outlet and thus controlling its temperature. To prevent vibration from the motor from being transmitted to the housing, a shock-absorbing sleeve 200 is installed around the motor. A heat insulation cylinder 400 is installed around the heating module to prevent heat from the heating module from being transferred to the housing. A motor bracket 201 is installed outside the heat insulation cylinder and shock-absorbing sleeve, inside the left and right housings, with the first fluid channel located within the motor bracket. An air outlet assembly 60 is installed between the first air outlet 105 and the air outlet screen 80. The fluid discharged from the first air outlet 105 has its flow characteristics altered by the air outlet assembly before being discharged through the air outlet screen. Figure 1 and Figure 12 As shown, the air outlet mesh 80 can be in the form of an isolation hole or an isolation groove 800. It only needs to prevent larger particles from entering the housing, and will not be described in detail here.

[0074] Furthermore, such as Figures 2-5As shown, the air outlet assembly 60 includes a fixed plate 604 connected to the motor bracket 201, and multiple sets of blades 605 disposed on the fixed plate. The other end of each blade is connected to an adjusting plate 603. The multiple sets of blades form a closed loop with openings at both ends. A second fluid channel 600 is formed inside the closed loop. A second air inlet 601 is formed on the side of the closed loop closest to the fixed plate 604, i.e., the fixed end of the blade forms the second air inlet. A second air outlet 602 is formed on the other side of the closed loop, i.e., the movable end of the blade forms the second air outlet. The second fluid channel 600 is located between the second air inlet and the second air outlet. The second air outlet is close to the air outlet mesh. The second air inlet 601 is connected to the first air outlet 105, allowing air passing through the first air outlet 105 to enter the second air inlet, then flow into the second air outlet within the second fluid channel, and finally be discharged through the air outlet mesh. A front locking ring 70 is provided on the other side of the housing. The front locking ring is connected to the housing and the air outlet assembly is placed between the front locking ring and the housing. An air outlet mesh is provided between the front locking ring and the air outlet assembly.

[0075] Furthermore, such as Figures 6-8 As shown, the adjusting disc 603 and the blade 605 are connected by a connecting rod assembly 606. One end of the connecting rod assembly is connected to the lower end of the blade, and the other end is connected to the adjusting disc 603. The adjusting disc has a protruding adjusting part 6030. Rotating the adjusting part drives the connecting rod assembly to rotate, thereby causing the blade 605 to rotate synchronously to change the size of the second air outlet 602. The lower end of the blade 605 is fixedly connected to the fixed disc, so the size of the second air outlet 602 changes. When the adjusting disc 603 rotates, it drives the upper end of the connecting assembly 606 to rotate. The lower end of the connecting assembly is connected to the lower end of the blade. When the connecting rod assembly rotates, it drives the blade to rotate, thereby causing the upper end of the blade to close or open to change the size of the second air outlet. To limit the adjustment range of the second air outlet size, a stroke groove 700 can be provided on the outside of the housing or on the front locking ring 70. The adjusting part can only rotate within the stroke groove to adjust the size of the second air outlet.

[0076] Furthermore, such as Figures 9-11As shown, a driven post 6051 is provided at the lower end of the blade 605. The lower end of the connecting rod assembly is connected to the driven post. Multiple sets of connecting blocks 6031 are provided on the adjusting plate, and the upper end of the connecting rod assembly is connected to the connecting blocks. The connecting rod assembly 606 includes a lower connecting frame 6064 connected to the driven post 6051 and an upper connecting frame 6060 connected to the connecting blocks. The upper connecting frame is connected to an upper connecting rod 6062 by a pin 6061, and the lower connecting frame is connected to a lower connecting frame 6063 by a pin 6061. The upper and lower connecting rods are also fixedly connected. The upper connecting frame is also connected to the connecting block 6031 by a pin 6061, and the lower connecting frame is connected to the driven post 6051 by a pin. Therefore, the lower connecting frame can rotate on the driven post, the upper connecting frame can rotate relative to the connecting blocks, and the lower connecting rod can also rotate relative to the lower connecting frame, while the upper connecting rod can rotate relative to the upper connecting frame. When a rotational force is applied to the adjusting disc 6030, causing it to rotate, the position of the connecting block changes, causing the upper connecting frame 6060 to rotate. This pulls the upper connecting frame to move with the connection, continuously causing the upper connecting rod to rotate relative to the upper connecting frame, and driving the upper and lower connecting rods to rotate as well. After the lower connecting rod rotates, it pulls the lower connecting frame to rotate, applying a pushing force to the driven column. Since the lower end of the blade is fixed, only the upper end of the blade can move, forming a closed or open state, thereby adjusting the size of the second air outlet 602. To improve the adjustment feel, a spring piece 607 is provided on the side of the adjusting disc 603. The spring piece contacts the front locking ring to provide a tactile feedback for the adjustment positions. Simultaneously, multiple sets of blades partially overlap to form an overlapping section 6050. Since the rotation of the blades changes the size and shape of this overlapping section, the blades move in an inclined manner when the adjusting disc rotates, causing the upper ends of the blades to close or open. This changes the area of ​​the overlapping section. When the overlapping section is a parallelogram or near-parallelogram, the airflow from the second air outlet is spiral-shaped; when rotated to a smaller second air outlet, the airflow through the second air outlet is straight-lined, thus allowing adjustment of the airflow pattern. Since the motor produces the same airflow at the same power, if the second air outlet becomes smaller, the wind speed will increase, thus adjusting the airflow velocity. Similarly, with the motor's contribution unchanged, if the area of ​​the second air outlet increases, the airflow volume can be increased, thus adjusting the airflow rate. Therefore, by rotating the adjusting disc to change the area and shape of the second air outlet, the physical parameters and behavior patterns of the airflow through the second air outlet 602 can be adjusted, making operation more convenient. In this embodiment, the linkage assembly rotates synchronously by adjusting the rotation of the adjustment disc, and the linkage assembly applies a pulling or pushing force to the blades to make the upper end of the blades close or open, thereby realizing the adjustment of the size of the second air outlet area.

[0077] The preferred embodiment of this utility model is a vector-controlled hair dryer assembly and device; the difference from embodiment one is that, as Figures 13-16The diagram shown is a simplified illustration, only showing the portion where the housing connects to the air outlet assembly, omitting the rest of the housing. The front locking ring 70 has an internal thread, and the outer wall of the housing 10 has an external thread corresponding to the internal thread, allowing the front locking ring to rotate on the housing. A stroke groove 700 is also provided on the side of the housing. The air outlet assembly 60 includes a fixed plate 604 connected to the motor bracket 201. The lower end of the fixed plate is connected to the motor bracket via multiple sets of gaskets 608, which isolate the fixed plate from the heating module, preventing heat transfer from the heating module to the fixed plate. The fixed plate also has multiple sets of blades 605, which together form a closed loop. Within this closed loop is a second fluid channel 600. One side of the second fluid channel is a second air inlet 601, and the other side is a second air outlet 602. An adjusting plate 603 is placed around the blades, and its radius is smaller than the outer diameter of the closed loop when not under stress. The adjusting plate can move radially on the blades to apply pressure to different parts of the blades, thereby changing the size of the second air outlet. An adjustment part 6030 is provided on the outer periphery of the adjustment disc corresponding to the stroke groove 700. The adjustment part is located within the stroke groove, and stripes are provided on the outer side of the front locking ring to increase friction. When the front locking ring is rotated, the front locking ring moves towards the housing and pushes the adjustment part 6030 to move within the stroke groove, causing the adjustment disc 603 to move towards the fixed disc 604. During the movement, since the radius of the adjustment disc is smaller than the radius of the closed loop formed by the blades, the adjustment disc will exert a thrust on the blades to make them close. During the closing process, the size of the second air outlet changes. The closer the adjustment disc is to the fixed disc, the smaller the second air outlet closes. When the adjustment disc moves away from the fixed disc, since the thrust of the adjustment disc on the blades gradually decreases, the closed blades will gradually open, thereby increasing the area of ​​the second air outlet until it is fully open. Therefore, the area adjustment size of the second air outlet can be designed according to the length of the stroke groove. The specific design can be derived from a finite number of designs, which will not be repeated here. The changes in the area size of the second air outlet caused by the change in the length of the stroke groove should all fall within the protection scope of this utility model. In this embodiment, the rotation of the front locking ring 70 drives the adjustment plate 603 to move up and down. During the up and down movement of the adjustment plate, a squeezing force is applied to different parts of the blade to make the blade close, thereby changing the size of the second air outlet area. After the squeezing force disappears, the blade returns to its original position, which can increase the size of the second air outlet area.

[0078] The preferred embodiment of this utility model is a vector control hair dryer assembly and device; such as... Figures 17-19As shown, the difference from Embodiment 1 is that the housing 10 is in a straight line shape, and the outside of the housing forms the handle 100 for gripping. The handle can also be equipped with multiple control buttons 300 connected to the control board 30, such as the power button for the hair dryer, the motor operating mode adjustment button, and the heating temperature adjustment button for the heating module. These buttons can also be used to control the hair dryer in Embodiments 1 and 2. Furthermore, in Embodiments 1 and 2, the first fluid channel 103 and the second fluid channel 600 are parallel, while in this embodiment, the angle between the first fluid channel and the second fluid channel is 75 degrees.

[0079] Furthermore, such as Figures 20-22 As shown, the air outlet assembly 60 includes a fixed plate 604 connected to the housing. The fixed plate has openings on both its upper and lower sides and is hollow inside. A heating component 40 is connected to the lower end of the fixed plate. A nozzle 605 is located inside the fixed plate. The lower part of the nozzle slides within the fixed plate, and the upper part slides at the upper opening. A second air outlet 602 is formed by the gap between the outer wall of the nozzle and the upper opening of the fixed plate. Therefore, the upper part of the nozzle can be cone-shaped. When the cone moves up and down, the area of ​​the second air outlet changes. Simultaneously, the gap between the outer wall of the nozzle and the inner wall of the fixed plate forms a second fluid channel 600. A second air inlet 601 is located below the fixed plate. Fluid heated by the heating component enters the second fluid channel through the second air inlet 601 and is then discharged through the second air outlet. To facilitate control of the nozzle's up-and-down movement, an adjusting plate 603 is connected above the nozzle. The adjusting plate is positioned between the housing and the fixed plate and can rotate on the fixed plate. Rotation causes the nozzle to move up and down, thereby changing the size of the second air outlet. Two sets of limit blocks 6040 are provided above the fixed plate, forming a travel groove between the two sets of limit blocks. A limit post 6032 is provided at the lower end of the adjustment plate corresponding to the travel groove. The limit post can only move within the travel range limited by the travel groove. In order to make the adjustment more tactile, multiple sets of gear holes 6042 are provided in the travel groove. At the same time, a ball bearing 6034 and a spring are provided in the limit post. When the ball bearing slides to different gear holes, the current gear state can be formed, and the spring can also facilitate the adjustment of the next gear.

[0080] Furthermore, such as Figures 22-24As shown, a pressing column 6033 is provided in the middle of the adjusting plate 603, and a receiving cavity 6052 is provided in the middle of the nozzle 605 corresponding to the pressing column. A force-bearing surface 6053 is provided in the receiving cavity, which contacts the pressing column. The force-bearing surface is inclined, meaning that different positions of the force-bearing surface have different heights in the vertical direction. When the adjusting plate rotates, the pressing column 6033 contacts the force-bearing surface and pushes the force-bearing surface to move, causing the nozzle to move, thereby changing the position of the nozzle in the vertical direction and thus changing the size of the second air outlet. To ensure that the nozzle can only move in the vertical direction, a sliding groove 6043 is provided inside the fixed plate 604, and an adjusting part 6030 is provided at the lower end of the nozzle corresponding to the sliding groove. The adjusting part moves within the sliding groove. A spring-loaded retainer 6041 is provided at the lower end of the nozzle. When the adjusting disc pushes the nozzle downwards to increase the area of ​​the second air outlet 602, the spring is compressed simultaneously. When the adjusting disc is rotated in the opposite direction, the spring returns to its original position, pushing the nozzle upwards to reduce the area of ​​the second air outlet, thus resetting the second air outlet. A hollow cavity 6031 is provided in the middle of the adjusting disc corresponding to the second air outlet, where an air outlet mesh or other structure can be installed for isolation. In this embodiment, the rotation of the adjusting disc moves the nozzle up and down, changing the area of ​​the second air outlet. After the force of the adjusting disc disappears, the nozzle returns to its original position under the action of the spring, or the spring pushes the nozzle upwards to reduce the area of ​​the second air outlet.

[0081] The preferred embodiment of this utility model is a vector-controlled hair dryer assembly and device; the difference from the above embodiments is that, Figures 25-26 As shown, the adjusting disc 603 is sleeved on the outside of the housing 10, and the outer wall of the housing is provided with ribs 108. The adjusting disc is provided with rib grooves corresponding to the ribs, so that the adjusting disc can only move up and down along the radial direction of the housing.

[0082] Furthermore, such as Figures 25-26As shown, blade 605 includes outer blade 6057 and inner blade 6056. The lower ends of both the inner and outer blades are rotatably connected to the housing, and the upper ends are connected to the adjusting plate 603 via a chain rod 611. The outer blade 6057 and inner blade 6056 form a closed loop, with the closed loop formed by the inner blades placed inside the closed loop formed by the outer blades. One end of the closed loop is the second air inlet 601, and the other end is the second air outlet 602. The interior is the second fluid channel 600. When the adjusting plate moves up and down along the radial direction of the housing, it pulls the chain rod up and down, transmitting the pulling force to the blades to close or open them. It can then be locked at the current adjustment position using a conventional locking mechanism, which will not be described in detail here. Only one set of outer blades or one set of inner blades can be set. When two sets of overlapping blades are set, better vertical airflow can be formed. The overlap of the inner and outer blades can prevent fluid from flowing out through the blade gaps, allowing the fluid to be completely discharged through the second air outlet. Simultaneously, the chain rods should be staggered; that is, if one set of chain rods is connected to the inner blade, then its two adjacent sets of chain rods must be connected to the outer blade; similarly, if one set of chain rods is connected to the outer blade, then its two adjacent sets of chain rods must be connected to the inner blade. It should be noted that the size of the second air outlet area can be adjusted with only minor adjustments to the adjusting disc. In this embodiment, the up-and-down movement of the adjusting disc 603 drives the chain rods to move, and the other end of the chain rods applies a pulling or pushing force to the blades, thus changing the size of the second air outlet area formed at the moving end of the blades.

[0083] The preferred embodiment of this utility model is a vector-controlled hair dryer assembly and device; the difference from the above embodiments is that, Figures 27-31 As shown, the handle portion of the housing 10 is conical, and the angle between the first fluid channel 103 and the second fluid channel 600 is 75 degrees. The first fluid channel 103 is equipped with multiple sets of partition plates 107, which divide the first fluid channel into multiple sets of parallel sub-fluid channels. The inlet and outlet of each sub-fluid channel are the same. The fluid is divided into multiple sub-fluids by the partition plates, and each sub-fluid can have the same flow velocity within each sub-fluid channel, resulting in more uniform sub-fluid flow.

[0084] Furthermore, such as Figures 32-36As shown, the air outlet assembly 60 includes a fixed plate 604 connected to the motor bracket 201. Multiple sets of blades 605 are connected to the fixed plate. The multiple sets of blades form a closed loop, and the lower end of the blades is fixedly connected to the fixed plate to form a second air inlet 601 of a fixed size. The upper end of the blades moves to form a second air outlet 602 of an adjustable size. At the same time, the middle channel of the blades is a second fluid channel 600. An adjustment plate 603 is sleeved on the outside of the blades. By rotating the adjustment plate, a thrust is applied to the upper end of the blades to make the blades close. At the same time, the lower end of the blades is held by an elastic element. When the upper end of the blades closes, the elastic element will be stretched. After the thrust at the upper end of the blades disappears, the elastic element resets and pulls the upper end of the blades open, thereby realizing the adjustment of the size of the second air outlet.

[0085] Furthermore, such as Figures 32-37 As shown, an adjusting ring 608 is connected to the outside of the adjusting disc 603. The adjusting ring has multiple sets of tree-shaped horizontal grooves to increase the friction of its rotation. A synchronization groove 6080 is provided on the inner wall of the adjusting ring, and a synchronization post 6035 is provided on the outer wall of the adjusting disc corresponding to the synchronization groove. The synchronization post engages with the synchronization groove, causing the adjusting disc to rotate synchronously when the adjusting ring rotates. To provide a more tactile feel during adjustment, the adjusting disc has gear teeth on its exterior and a gear strip 610 on its side, which also has gear teeth 6100. The gear teeth engage with each other to provide a tactile feel for the adjustment. It should be noted that the gear strip remains stationary; the gear adjustment sound is produced when the gear teeth contact each other as the adjusting disc rotates. Multiple sets of ribs 6036 are provided inside the adjusting disc 603, and protrusions 6054 are provided on the outer side of the blades corresponding to these ribs. When the adjusting disc rotates, different ribs contact the protrusions to adjust the size of the second air outlet. In this invention, multiple sets of bone positions are provided, each set including a first bone position 6036, a second bone position 6037, and a third bone position 6038. When the protruding post is placed at the first bone position, the size of the second air outlet is as follows: Figure 32 As shown in the figure, when the adjusting disc is rotated further to position the protrusion at the second rib, the size of the second air outlet is as follows: Figure 33 As shown in the diagram, continue rotating the adjustment disc until the protrusion is positioned at the third rib; the size of the second air outlet will then be as shown. Figure 34The size is shown. More sets of ribs can be set as needed to achieve more adjustments to the size of the second air outlet; details are not elaborated here. Simultaneously, an elastic groove 6055 is provided at the lower end of the protruding column. The elastic element (not shown in the figure) is placed in the elastic groove. When the blades close, one end of the elastic groove will be open, providing tensile force to the elastic element, causing it to stretch. When the adjusting disc rotates from the second rib position to the first rib position, since the rib cannot apply tensile force to the blades, the deformation restoring force of the elastic element will pull one end of the elastic groove to close. Correspondingly, the movable end of the blade tends to open, thus increasing the size of the second air outlet. At the same time, there is an overlapping portion 6050 between adjacent sets of blades 605. When the blades are closed, the overlapping area gradually increases and becomes relatively parallel. At this time, the fluid passing through the second air outlet will exhibit a spiral shape, thus changing the fluid shape. In this embodiment, the rotation of the adjusting ring 608 drives the adjusting disk 603 to rotate. At the same time, different ribs of the adjusting disk contact the protrusions 6054 of the blades, applying a thrust to the blades to close the movable ends of the blades and reduce the size of the second air outlet. Meanwhile, one side of the elastic element groove is in an open state, stretching the elastic element. When the adjusting disk is rotated, the ribs cannot apply a thrust to the protrusions. The deformation restoring force generated by the elastic element pulls one end of the elastic element groove to close. At this time, one side of the movable end of the blade tends to open to increase the size of the second air outlet, thereby achieving the adjustment of the area of ​​the second air outlet.

[0086] The preferred embodiment of this utility model, a vector-controlled hair dryer assembly and device, differs from embodiment five in that, as... Figures 38-39 As shown, the second fluid channel 600 and the first fluid channel 103 are parallel straight lines. The difference between the included angle of the first fluid channel and the second fluid channel lies only in changing the air outlet angle. Meanwhile, a gear mark is provided on the outer side of the adjusting ring, and a gear position consisting of a ball bearing 6034 and a spring is provided on the outer side of the housing. A gear position hole is correspondingly provided at the lower end of the adjusting ring. When the adjusting disc rotates, the ball bearing enters different gear position holes, indicating the current size of the second air outlet. The specific adjustment method is the same as in Embodiment 5, and will not be repeated here.

[0087] The preferred embodiment of this utility model, the seventh, is a vector-controlled hair dryer assembly and device; the difference from embodiment five is that, as... Figures 40-41 As shown, the second fluid channel 600 and the first fluid channel are at a 90-degree right angle. The adjustment settings are the same as in Embodiment Six, while the adjustment of the size of the second air outlet area is the same as in Embodiment Five, and will not be repeated here.

[0088] Furthermore, such as Figures 42-43As shown, blade 605 includes inner blade 6056 and outer blade 6057. The inner and outer blades form a closed loop, with the inner blade placed inside the outer blade. Simultaneously, the inner blade is positioned at the connection point of the two sets of outer blades, sealing the connection gap of the outer blades. Similarly, the outer blade is positioned at the connection point of the two sets of inner blades, sealing the connection gap of the inner blades. At this point, the fluid flowing through the second air outlet 603 is linear. Only a protruding post 6054 needs to be provided on the outer side of the outer blade. After the outer blade is forced to close, it pushes the inner blade to close, reducing the area of ​​the second air outlet. Simultaneously, elastic grooves 6055 are provided at the lower ends of both the inner and outer blades. After the thrust of the outer blade disappears, the deformation restoring force of the elastic element pulls one side of the elastic groove to close, thereby opening the movable end of the blade to increase the area of ​​the second air outlet.
