Description

Technical Field

[0001] The present invention relates to the field of fluid regulating components, and particularly to a vector control hair dryer assembly and its device. Background Art

[0002] As a common personal care and industrial electrical appliance, the core function of a hair dryer is to drive a fan by a motor to generate an air flow, which is heated by a heating element and then discharged from the air outlet to achieve functions such as drying and shaping of a target object. The air outlet of traditional hair dryers usually adopts a circular or flat design with a fixed aperture, resulting in significant limitations in terms of functional expandability and use flexibility.

[0003] Currently, the speed adjustment of commercially available hair dryers mainly relies on the linear adjustment of the motor power, that is, by changing the supply voltage or current to adjust the fan speed. 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, due to the fixed cross-sectional area of the air flow channel, turbulent flow is likely to occur, causing abnormal noise; (3) It is difficult to achieve fine control of the air flow characteristics solely by power adjustment, and key parameters such as air pressure and air flow concentration lack the ability of independent adjustment.

[0004] In terms of the adjustment of the air outlet form, the prior art generally uses detachable nozzle accessories to achieve the air flow guiding function, and users need to manually replace different-shaped air guiding covers to meet the styling needs. Such a solution has obvious pain points in use: (1) The process of replacing accessories is cumbersome, affecting the continuity of operation; (2) Accessories are prone to being lost or damaged during storage; (3) The discrete accessory combinations are difficult to achieve continuous gradual adjustment of the air outlet parameters, limiting the diversity of styling effects.

[0005] In addition, the fixed air outlet design results in an unadjustable contact area between the air flow and the wind-receiving surface. When performing special styling (such as local shaping, curly hair styling, etc.), users often need to frequently change the distance or angle of the hair dryer, which not only increases the operation complexity but also easily causes the risk of thermal 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, and through structural innovation, continuously adjust the size and shape of the air outlet, so as to break through the technical bottleneck of traditional adjustment methods and improve the energy efficiency of the device and the user experience. Summary of the Invention

[0007] The technical problem to be solved by the present invention is that the air outlet of traditional hair dryers usually adopts a circular or flat design with a fixed aperture, resulting in significant limitations in terms of functional expandability and use flexibility. In view of the above defects of the prior art, a vector control hair dryer assembly and its device are provided.

[0008] To solve the above technical problems, the technical solution adopted by the present invention is as follows: Construct a vector control hair dryer assembly, including a fixed disk and a blade group arranged on the fixed disk. The blade group forms a closed loop. One end of the blade group forms a second fluid inlet with a constant area. The other end forms a second fluid outlet. 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 is discharged from the second fluid outlet. It is characterized in that: the fluid regulating assembly further includes a regulating assembly connected to the blade group. The regulating assembly acts to change the size of the second fluid outlet, so that the area or shape of the second fluid outlet changes to change the physical parameters and / or behavior patterns of the fluid passing through the second fluid outlet.

[0009] Preferably, the side of the blade group connected to the fixed disk is the fixed end, and the other side of the blade group is the regulating end. The regulating assembly rotates to change the shape of the regulating end, so that the area or shape of the second fluid outlet changes.

[0010] Preferably, the regulating assembly includes a regulating disk. The regulating disk rotates to make the regulating end of the blade group act to change the area of the second fluid outlet; The action of the regulating end includes the regulating end closing or opening to change the area of the second fluid outlet; Or the regulating end moves to change the area of the second fluid outlet.

[0011] Preferably, the regulating disk is connected to the blade group through multiple sets of connecting rod assemblies. The rotation of the regulating disk drives the connecting rod assemblies to rotate and drives the regulating end of the blade group to close or open to change the area of the second fluid outlet.

[0012] Preferably, the connecting rod assembly includes a connecting frame connected to the regulating disk and the blade group, and a connecting rod connecting the two sets of connecting frames. The connecting frame can rotate relative to the regulating disk and the blade group, and the connecting rod can rotate relative to the connecting frame. The rotation of the regulating disk drives the connecting rod assembly to rotate, and applies a pulling force to the blade group through the connecting rod assembly to make the regulating end close or open.

[0013] Preferably, the regulating disk moves up and down to apply a converging force to the blade group to make the regulating end close and change the area of the second fluid outlet. After the regulating disk moves and releases the converging force on the blade group, the blade group restores its deformation to make the regulating end open and change the area of the second fluid outlet. The radius of the regulating disk is smaller than the radius of the blade group in the non-loaded state.

[0014] Preferably, the blade group is a nozzle. The upper part of the nozzle is conical, and there is a gap between the outer wall of the nozzle and the inner wall of the adjustment disk to form a second fluid outlet. The rotation of the adjustment disk drives the nozzle to move up and down to increase the area of the second fluid outlet. An elastic member is provided at the lower end of the nozzle. When the nozzle moves downward, the elastic member is compressed by the force. When the adjustment disk rotates without applying a thrust to the nozzle, the elastic member deforms and recovers to push the nozzle to move up and down to reduce the area of the second fluid outlet.

[0015] Preferably, a pressing column is provided at the lower end of the adjustment disk. A receiving cavity is correspondingly provided in the middle of the nozzle for the pressing column. A stress surface is provided in the receiving cavity. The stress surface is inclined. The rotation of the adjustment disk causes the pressing column to contact different stress surfaces, so that the nozzle moves downward to increase the area of the second fluid outlet.

[0016] Preferably, the adjustment disk is connected to the blade group through a link rod. The rotation or up-and-down movement of the adjustment disk drives the link rod to move and apply a closing force or an opening force to the adjustment end, so that the adjustment end closes or opens to change the area of the second fluid outlet.

[0017] Preferably, multiple different bone positions are provided inside the adjustment disk. Convex columns are correspondingly provided outside the blade group for the bone positions. When the adjustment disk rotates, the convex columns contact different bone positions to close the blades to reduce the area of the second fluid outlet. An elastic member is provided at the fixed end of the blade group. When the adjustment end of the blade group closes, the elastic member is stretched by the force. When the bone position does not generate a thrust on the convex column, the elastic member deforms and recovers to pull the blade group to open the adjustment end to increase the area of the second fluid outlet.

[0018] Preferably, the blade group is formed by enclosing multiple groups of blades. The lower ends of the multiple groups of blades are fixedly connected to a fixed disk, and the upper ends are movably connected to an adjustment assembly and change the enclosed area of the movable ends under the action of the adjustment assembly. A travel groove is further provided on the adjustment assembly. The travel groove limits the adjustment range of the second fluid outlet. A gear position assembly is further provided on the adjustment assembly. When the adjustment assembly rotates, the gear position adjustment feeling is felt through the gear position assembly.

[0019] Preferably, partial overlap exists between adjacent two groups of blades. The movement of the movable ends of the blades changes the area or shape of the overlapping part, so that the fluid passing through the second fluid outlet is spiral or linear; Or the blade includes multiple groups of outer blades and multiple groups of inner blades. The multiple groups of outer blades enclose to form a closed loop. The multiple groups of inner blades enclose to form a closed loop. The inner blades are placed inside the outer blades, and the connection part between adjacent two groups of inner blades is placed in the middle of the outer blades, and the connection part between adjacent two groups of inner blades is placed in the middle of the inner blades.

[0020] An apparatus is constructed, which includes a housing, as well as 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 of the housing and a first fluid outlet on the other side. The heating module is placed between the driving module and the first fluid outlet. It is characterized in that: at the first fluid outlet, there is provided a vector control hair dryer assembly as described above. The first fluid outlet communicates with a second fluid inlet. The driving assembly sucks the fluid from the first fluid inlet into the first fluid channel, and enters the second fluid inlet through the first fluid outlet, and then is discharged through the second fluid outlet within the second fluid channel.

[0021] Preferably, a handle is further provided on the housing. The handle is arranged perpendicular 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 from the second fluid outlet passes through the air outlet net for operation. The included angle between the first fluid channel and the second fluid channel is 75° - 180°.

[0022] The beneficial effects of the present invention are as follows: By providing an air outlet assembly at the first air outlet, the size and shape of the second air outlet are changed, thereby changing the physical parameters and behavior patterns of the fluid passing through the second air outlet. By rotating or pulling the adjustment disk, the area of the second air outlet becomes smaller, so as to achieve a greater wind speed under the same power, improve the wind speed and air volume while reducing energy consumption, and produce less noise. At the same time, according to the arrangement form of the blades, while adjusting the size of the second air outlet, the arrangement of the blades is changed, thereby changing the shape of the fluid passing through the second air outlet. The air outlet shape can be changed without replacing accessories, the operation is more convenient, the function expansion is improved, and the use is more flexible. The movable ends of the blades can be closed or opened by rotating or pulling the adjustment disk, or different thrusts can be applied to the movable ends of the blades by pulling the adjustment disk up and down to close or open the movable ends of the blades, or the air nozzle can be moved up and down by rotating the adjustment disk to increase or decrease the distance between the air nozzle and the inner wall of the adjustment disk, or pulling the adjustment disk up and down to apply a pulling force or a thrust to the movable ends of the blades; or by rotating the adjustment disk, different bone positions apply thrusts to the blades 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.

Detailed implementation manners

[0024] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely below. Apparently, the described embodiments are only partial embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The vector control hair dryer assembly and its device according to the first preferred embodiment of the present invention; the fluid regulating assembly is used to regulate the flow rate, flow volume, form, etc. of the fluid, and the device is used to generate the fluid. For example, the device can be a device that forms the fluid such as a hair dryer or a hair blowing tube. By installing the fluid regulating assembly at the air outlet of the device, the fluid generated by the device can be regulated. For example, regulating the speed of the fluid flow, regulating the size of the fluid flow volume, or regulating the form of the fluid such as vertical wind or spiral wind, etc. are collectively referred to as the flow characteristics of the fluid. The flow characteristics of the fluid include the physical parameters and behavior patterns of the fluid. The flow characteristics of the fluid formed by the device are regulated by the fluid regulating assembly. In the present invention, the hair dryer is taken as an example for specific description, and other related devices that can generate fluid flow characteristics also fall within the protection scope of the present invention. After regulating the flow characteristics of the fluid by the fluid regulating assembly and using it to dry hair or other objects that need to be dried, the device of the present invention can be applied.

[0026] Specifically, such as Figures 1 - 3As shown, the hair dryer includes a housing 10. The housing 10 is generally T-shaped as a whole, and the housing is detachably connected by a left housing 101 and a right housing 102. The lower part of the housing forms a handle 100 for holding. The upper part of the housing forms a first fluid channel 103 for fluid. One side of the first fluid channel forms a first air inlet 104, and the other end forms a first air outlet 105. A rear cover 50 is provided at the first air inlet. The left housing and one end of the right housing are connected through the rear cover. At the same time, multiple groups of isolation holes are provided on the rear cover. The isolation holes communicate with the first air inlet. The fluid enters the first fluid channel 103 through the isolation holes. At the same time, the isolation holes can 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 provided in the upper part of the housing 10. The other ends of the left housing and the right housing are connected by a front lock ring 70, and an air outlet net 80 is sleeved inside the front lock ring. Multiple groups of isolation holes are also provided on the air outlet net to prevent particulate objects from entering the first fluid channel. The heating module 40 is arranged near the first air outlet 105, and the heating module is placed between the motor 20 and the first air outlet. The motor causes a fluid to be formed in the first fluid channel. The fluid enters through the first air inlet 104 and then is discharged through the first air outlet. When the fluid passes through the heating module, the fluid can be heated, so as to realize discharging the heated fluid from the first air outlet to control the temperature of the fluid. In order to prevent the vibration feeling from being transmitted to the housing when the motor works, a shock-absorbing sleeve 200 is sleeved outside the motor. At the same time, a heat-insulating cylinder 400 is sleeved outside the heating module to prevent the heat generated by the heating module from being transmitted to the outer shell. A motor bracket 201 is provided outside the heat-insulating cylinder and the shock-absorbing sleeve. The motor bracket is placed inside the left housing and the right housing, and the first fluid channel is inside the motor bracket. An air outlet assembly 60 is provided between the first air outlet 105 and the air outlet net 80. The fluid discharged from the first air outlet 105 changes the flow characteristics of the fluid under the action of the air outlet assembly and then is discharged through the air outlet net for operation. As Figure 1 and Figure 12 shown, the air outlet net 80 can be in the form of isolation holes or in the form of isolation grooves 800, as long as it can prevent larger particulate objects from entering the housing, and no specific description will be made here.

[0027] Furthermore, as Figures 2 - 5As shown, the air outlet assembly 60 includes a fixed disk 604 connected to the motor bracket 201, and multiple groups of blades 605 arranged on the fixed disk. The other ends of the blades are connected to the adjustment disk 603. At the same time, the multiple groups of blades enclose a closed loop, and there are openings at both ends of the closed loop. 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 close to the fixed disk 604, that is, the fixed ends of the blades form the second air inlet. A second air outlet 602 is formed on the other side of the closed loop, that is, the movable ends of the blades form the second air outlet. The second fluid channel 600 is between the second air inlet and the second air outlet. The second air outlet is close to the air outlet net. The second air inlet 601 is communicated with the first air outlet 105, so that the air passing through the first air outlet 105 enters the second air inlet, then flows to the second air outlet in the second fluid channel, and is discharged through the air outlet net. A front lock ring 70 is arranged on the other side of the housing. The front lock ring is connected to the housing to place the air outlet assembly between the front lock ring and the housing, and an air outlet net is arranged between the front lock ring and the air outlet assembly.

[0028] Further, as Figures 6 - 8 shown, the adjustment disk 603 and the blades 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 of the connecting rod assembly is connected to the adjustment disk 603. The adjustment disk is provided with a protruding adjustment part 6030. By rotating the adjustment part, the connecting rod assembly is driven to rotate, thereby driving the blades 605 to rotate synchronously to change the size of the second air outlet 602. The lower ends of the blades 605 are fixedly connected to the fixed disk. Therefore, when the adjustment disk 603 rotates, the size of the second air inlet 602 changes. When the adjustment disk 603 rotates, the adjustment disk drives the upper end of the connecting component 606 to rotate, and the lower end of the connecting component is connected to the lower end of the blade. When the connecting rod assembly rotates, the blades will be driven to rotate, so that the upper ends of the blades are closed or opened to change the size of the second air outlet. In order to limit the adjustment range of the size of the second air outlet, a travel slot 700 can be arranged on the outer side of the housing or the front lock ring 70, and the adjustment part can only rotate in the travel slot to adjust the size of the second air outlet.

[0029] Further, as Figures 9 - 11As shown, a driven column 6051 is provided at the lower end of the blade 605. The lower end of the connecting rod assembly is connected to the driven column. Multiple connecting blocks 6031 are provided on the adjusting disc. 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 column 6051 and an upper connecting frame 6060 connected to the connecting blocks. The upper connecting frame is connected with an upper connecting rod 6062 through a pin 6061, and the lower connecting frame is connected with a lower connecting rod 6063 through a pin 6061. At the same time, the upper connecting rod and the lower connecting rod are fixedly connected. The upper connecting frame is also connected to the connecting block 6031 through a pin 6061, and the lower connecting frame is connected to the driven column 6051 through a pin. Therefore, the lower connecting frame can rotate on the driven column, the upper connecting frame can rotate relative to the connecting block, at the same time, the lower connecting rod can also rotate relative to the lower connecting frame, and the upper connecting rod can rotate relative to the upper connecting frame. When a rotational force is applied to the adjusting disc 6030 to rotate the adjusting disc, the position of the connecting block changes, causing the upper connecting frame 6060 to rotate, and pulling the upper connecting frame to move along with the connection. Continuously, the upper connecting rod rotates relative to the upper connecting frame and drives the upper connecting rod and the lower connecting rod to rotate. After the lower connecting rod rotates, it will pull the lower connecting frame to rotate and apply a driving 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 realizing the adjustment of the size of the second air outlet 602. In order to make the adjustment feel better, a spring piece 607 is provided on the side of the adjusting disc 603. The spring piece contacts the front lock ring to achieve the sense of adjustment gear. At the same time, multiple blades partially overlap to form an overlapping part 6050. Since the area and shape of the overlapping part will change after the blades rotate, when the adjusting disc rotates, the blades move in an inclined shape, causing the upper ends of the blades to close or open. At this time, the area of the overlapping part changes. When the overlapping part is a parallelogram or a quasi-parallelogram, the air flow through the second air outlet is in a spiral shape; when rotating to a smaller second air outlet, the air flow through the second air outlet will be in a straight line shape. In this way, the flow form of the air through the second air outlet can be adjusted; since the air volume generated by the motor is the same under the same power, at this time, if the second air outlet becomes smaller, the air velocity will become larger. In this way, the adjustment of the air velocity can also be realized; similarly, with the same power of the motor, if the area of the second air outlet becomes larger, the air volume can be increased, thereby realizing the adjustment of the air volume. 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 air passing through the second air outlet 602 can be adjusted, and the operation is more convenient. In this embodiment, by rotating the adjusting disc, the connecting rod assembly rotates synchronously, and the connecting rod assembly applies a pulling force or a pushing force to the blade to cause the upper end of the blade to close or open, thereby realizing the adjustment of the size of the second air outlet area.

[0030] The vector control hair dryer assembly and its device according to the second preferred embodiment of the present invention; the difference from the first embodiment is as Figures 13 - 16As shown, for the sake of simplicity, only the part of the housing connected to the air outlet assembly is shown, while the other parts of the housing are omitted. An internal thread is provided inside the front lock ring 70, and an external thread corresponding to the internal thread is provided on the outer wall of the housing 10, so that the front lock ring can rotate on the housing. At the same time, a travel groove 700 is provided on the side of the housing. The air outlet assembly 60 includes a fixed disk 604 connected to the motor bracket 201. The lower end of the fixed disk is connected to the motor bracket through multiple groups of gaskets 608. The gaskets isolate the fixed disk from the heating module to prevent the heat of the heating module from being transferred to the fixed disk. At the same time, multiple groups of blades 605 are provided on the fixed disk. The multiple groups of blades enclose a closed loop, and a second fluid channel 600 is formed inside the closed loop. One side of the second fluid channel is the second air inlet 601, and the other side is the second air outlet 602. The adjusting disk 603 is placed outside the blades, and the radius of the adjusting disk is smaller than the outer diameter of the closed loop formed by the blades in the non-loaded state. And the adjusting disk can move in the radial direction of the blades to apply extrusion forces to different parts of the blades, so as to change the size of the second air outlet. An adjusting part 6030 corresponding to the travel groove 700 is provided on the outer periphery of the adjusting disk. The adjusting part is inside the travel groove. At the same time, stripes are provided on the outside of the front lock ring to increase the friction force. When the front lock ring is rotated, the front lock ring moves towards the housing side and pushes the adjusting part 6030 to move in the travel groove, so that the adjusting disk 603 moves towards the fixed disk 604. During the movement, since the radius of the adjusting disk is smaller than the radius of the closed loop formed by the blades, the adjusting disk will apply a thrust to the blades to make the blades close. During the closing process, the size of the second air outlet is changed. And the closer the adjusting disk is to the fixed disk, the smaller the second air outlet closes. When the adjusting disk moves away from the fixed disk, since the thrust of the adjusting disk on the blades gradually becomes smaller, the closed blades will gradually open, so that the area of the second air outlet increases until it is fully open. Therefore, the area of the second air outlet can be designed to be adjusted according to the length of the travel groove. The specific design can be obtained through a limited number of designs and will not be repeated here. And all changes in the area of the second air outlet only caused by the change of the length of the travel groove should fall within the protection scope of the present invention. In this embodiment, the rotation of the front lock ring 70 drives the adjusting disk 603 to move up and down. During the up and down movement of the adjusting disk, extrusion forces are applied to different parts of the blades to make the blades close, thereby changing the size of the area of the second air outlet. After the extrusion force disappears, the blades reset to increase the area of the second air outlet.

[0031] The vector control hair dryer assembly and its device of the third preferred embodiment of the present invention; as Figures 17 - 19As shown, the difference from the first embodiment is that the housing 10 is in a straight shape. At this time, the outside of the housing is the handle 100 part for holding. At the same time, multiple groups of control buttons 300 connected to the control board 30 can be set on the handle, such as the switch button of the hair dryer, the adjustment button for the working mode of the motor, and the adjustment button for the heating temperature of the heating module, etc. At the same time, the button part can also be used to control the hair dryer in the first embodiment and the second embodiment. And in the first embodiment and the second embodiment, the first fluid channel 103 and the second fluid channel 600 are parallel, while in this embodiment, the included angle between the first fluid channel and the second fluid channel is 75 degrees.

[0032] Furthermore, as Figures 20 - 22 shown, the air outlet assembly 60 includes a fixed disk 604 connected to the housing. Openings are provided on both the upper and lower sides of the fixed disk, and the inside is hollow. The heating assembly 40 is connected to the lower end of the fixed disk. A nozzle 605 is provided inside the fixed disk. The lower part of the nozzle slides inside the fixed disk, and the upper part slides at the upper opening. The second air outlet 602 is formed by the gap between the outer wall of the nozzle and the upper opening of the fixed disk. Therefore, the upper part of the nozzle can be set in a conical shape. When the cone moves up and down, the interface changes the area of the second air outlet. At the same time, the gap between the outer wall of the nozzle and the inner wall of the fixed disk forms the second fluid channel 600. The second air inlet 601 is below the fixed disk. The fluid heated by the heating component enters the second fluid channel through the second air inlet 601 and then is discharged through the second air outlet. To facilitate the control of the up and down movement of the nozzle, an adjustment disk 603 is connected above the nozzle. The adjustment disk is placed between the housing and the fixed disk and can rotate on the fixed disk. When rotating, it drives the nozzle to move up and down, thereby changing the size of the second air outlet. Two groups of limit blocks 6040 are provided above the fixed disk. A travel groove is formed between the two groups of limit blocks. A limit post 6032 is correspondingly provided at the lower end of the adjustment disk for the travel groove. The limit post can only move within the travel range defined by the travel groove. To make the adjustment more sense of gear, multiple groups of gear holes 6042 are provided in the travel groove. At the same time, a ball 6034 and a spring are provided inside the limit post. When the ball slides to different gear holes, the current gear state can be formed, and the spring also facilitates the adjustment of the next gear.

[0033] Furthermore, as Figures 22 - 24As shown, a pressing column 6033 is provided in the middle of the adjusting disc 603. A receiving cavity 6052 is provided in the middle of the air nozzle 605 corresponding to the pressing column. A stress surface 6053 is provided in the receiving cavity. The stress surface contacts the pressing column. The stress surface is inclined, that is, the heights of different positions of the stress surface in the vertical direction are different. When the adjusting disc rotates, the pressing column 6033 contacts the stress surface and pushes the stress surface to move, causing the air nozzle to move, thereby changing the position of the air nozzle in the vertical direction and changing the size of the second air outlet. In order to enable the air nozzle to move only in the vertical direction, a sliding groove 6043 is provided inside the fixed disc 604. An adjusting portion 6030 is provided at the lower end of the air nozzle corresponding to the sliding groove. The adjusting portion moves in the sliding groove. An elastic member fixing seat 6041 is provided at the lower end of the air nozzle. Elastic members such as springs are provided inside the elastic member fixing seat. When the adjusting disc pushes the air nozzle downward to increase the area of the second air outlet 602, the spring is synchronously compressed. When the adjusting disc is rotated in the opposite direction, the spring can be reset to push the air nozzle upward to reduce the area of the second air outlet, thereby realizing the reset of the second air outlet. And a hollow cavity 6031 is provided in the middle of the adjusting disc corresponding to the second air outlet. Structures such as an air outlet net can be provided at the hollow cavity to achieve the function of isolation. In this embodiment, the rotation of the adjusting disc pushes the air nozzle to move, causing the air nozzle to move up and down, thereby changing the area of the second air outlet, and resetting under the action of the elastic member after the thrust of the adjusting disc disappears or the elastic member pushes the air nozzle upward to reduce the area of the second air outlet.

[0034] The vector control hair dryer assembly and its device according to the fourth preferred embodiment of the present invention; the difference from the above embodiment is that, as Figures 25 - 26 shown, the adjusting disc 603 is sleeved outside the housing 10. At the same time, a rib position 108 is provided on the outer wall of the housing. The adjusting disc is provided with a rib groove corresponding to the rib position, so that the adjusting disc can only move up and down in the radial direction of the housing.

[0035] Furthermore, as Figures 25 - 26As shown in the figure, the blade 605 includes an outer blade 6057 and an inner blade 6056. The lower ends of both the inner blade and the outer blade are rotatably connected to the housing, and the upper ends are both connected to the adjustment disc 603 through link rods 611. Both the outer blade 6057 and the inner blade 6056 enclose a closed loop, and the closed loop formed by the inner blade is placed inside the closed loop formed by the outer blade. One end of the enclosed blade is the second air inlet 601, the other end is the second air outlet 602, and the inside is the second fluid channel 600. When the adjustment disc moves up and down along the radial direction of the housing, it will pull the link rod up and down and transmit the pulling force to the blade to make the blade close or open. Then it can be locked in the currently adjusted gear through a conventional locking method, which will not be specifically described here. It is also possible to only set a group of outer blades or a group of inner blades. When two sets of superimposed blades are set, a better vertical wind can be formed. The overlapping part of the inner blade and the outer blade can prevent the fluid from flowing away from the blade gap, so that the fluid is completely discharged through the second air outlet. At the same time, the link rods should be staggered, that is, if a group of link rods is connected to the inner blade, the two adjacent groups of link rods need to be connected to the outer blade; similarly, if a group of link rods is connected to the outer blade, the two adjacent groups of link rods need to be connected to the inner blade. It should be noted that only a small adjustment of the adjustment disc is required to adjust the area of the second air outlet. In this embodiment, the up and down movement of the adjustment disc 603 drives the link rod to move, and the other end of the link rod applies a pulling force or a pushing force to the blade, so that the area of the second air outlet formed by the movable end of the blade changes.

[0036] The vector control hair dryer assembly and its device according to the fifth preferred embodiment of the present invention; the difference from the above embodiment is that, as Figures 27 - 31 shown, the handle part of the housing 10 is conical, and at the same time, the included angle between the first fluid channel 103 and the second fluid channel 600 is 75 degrees. At the same time, a plurality of partition plates 107 are arranged in the first fluid channel 103. The partition plates divide the first fluid channel into a plurality of groups of parallel sub-fluid channels. The inlets and outlets of the sub-fluid channels are the same. The fluid is divided into multiple groups of sub-fluids by the partition plates. The sub-fluids can also have the same flow velocity in each group of sub-fluid channels, and at the same time, the wind sub-fluids are more uniform.

[0037] Furthermore, as Figures 32 - 36 shown, the air outlet assembly 60 includes a fixed disc 604 connected to the motor bracket 201. A plurality of groups of blades 605 are connected to the fixed disc. The plurality of groups of blades enclose a closed loop, and the lower ends of the blades are fixedly connected to the fixed disc to form a second air inlet 601 with a fixed size. The upper ends of the blades are movable to form an adjustable second air outlet 602. At the same time, the middle channel of the blade is the second fluid channel 600. An adjustment disc 603 is sleeved outside the blade. By rotating the adjustment disc, a pushing force is applied to the upper end of the blade to make the blade close. At the same time, the lower end of the blade is pulled by an elastic member. When the upper end of the blade closes, the elastic member will be stretched. After the pushing force at the upper end of the blade disappears, the elastic member resets and pulls the upper end of the blade to open, thereby realizing the adjustment of the size of the second air outlet.

[0038] Further, as Figures 32 - 37 shown, an adjusting ring 608 is externally connected to the adjusting disk 603. Multiple groups of tree-shaped transverse grooves are provided on the adjusting ring to increase the frictional force for the rotation of the adjusting ring. A synchronous groove 6080 is provided on the inner wall of the adjusting ring, and a synchronous post 6035 is provided on the outer wall of the adjusting disk corresponding to the synchronous groove. The synchronous post is snapped into the synchronous groove. When the adjusting ring rotates, the adjusting disk is driven to rotate synchronously. In order to make the adjustment have a more distinct sense of gear, gear teeth are provided on the outside of the adjusting disk, and a gear bar 610 is provided on the side of the adjusting disk. Gear teeth 6100 are also provided on the gear bar. The gear teeth are engaged with each other to achieve the sense of gear during adjustment. It should be noted that the gear bar is fixed, and when the adjusting disk rotates, the gear teeth contact to produce the gear adjustment sound. Multiple groups of bone positions 6036 are provided in the adjusting disk 603. Convex posts 6054 are provided on the outside of the blade corresponding to the bone positions. When the adjusting disk rotates, different bone positions contact the convex posts to adjust the size of the second air outlet. In the present invention, multiple groups of bone positions are provided. Each group of bone positions includes a first bone position 6036, a second bone position 6037, and a third bone position 6038. When the convex post is located at the first bone position, the size of the second air outlet is as Figure 32 shown, and when the adjusting disk is further rotated to place the convex post at the second bone position, the size of the second air outlet is as Figure 33 shown, and when the adjusting disk is further rotated to place the convex post at the third bone position, the size of the second air outlet is as Figure 34 shown. More groups of bone positions can also be provided according to needs to achieve more adjustments of the size of the second air outlet, which will not be specifically elaborated here. At the same time, an elastic part groove 6055 is provided at the lower end of the convex post. An elastic part (not shown in the figure) is placed in the elastic part groove. When the blades are closed, one end of the elastic part groove will be in an open state to provide a tensile force for the elastic part to stretch the elastic part. When the adjusting disk rotates from the second bone position to the first bone position, since the bone position cannot apply a pulling force to the blade, and at this time the deformation restoring force of the elastic part will pull one end of the elastic part groove to close, corresponding to the fact that the movable end of the blade is in an open trend at this time, so as to achieve an increase in the size of the second air outlet. At the same time, there is an overlapping part 6050 between two adjacent groups of blades 605. When the blades are in the closed state, the overlapping area gradually increases and is in a relatively parallel state. At this time, the fluid passing through the second air outlet will present a spiral shape, so as to achieve a change in the shape of the fluid. In this embodiment, the rotation of the adjusting ring 608 drives the rotation of the adjusting disk 603. At the same time, different bone positions of the adjusting disk contact the convex posts 6054 of the blade to apply a thrust to the blade to make the movable end of the blade close to reduce the size of the second air outlet. At the same time, one side of the elastic part groove is in an open state to stretch the elastic part. When the bone position cannot apply a thrust to the convex post when the adjusting disk rotates, the deformation restoring force generated by the elastic part pulls one end of the elastic part groove to close. At this time, one side of the movable end of the blade is in an open trend to increase the size of the second air outlet, so as to achieve the adjustment of the area size of the second air outlet.

[0039] The vector control hair dryer assembly and its device according to the sixth preferred embodiment of the present invention; the difference from the fifth embodiment is that, as Figures 38 - 39 shown, the second fluid passage 600 and the first fluid passage 103 are in a parallel straight shape, and the difference in the included angle between the first fluid passage and the second fluid passage only lies in changing the air outlet angle. At the same time, gear marks are provided on the outer side of the adjustment ring, and a gear composed of a ball 6034 and a spring is provided on the outer side of the housing. At the same time, gear holes are correspondingly provided at the lower end of the adjustment ring. When the adjustment disk rotates, the ball enters different gear holes, which can indicate the size of the current second air outlet. The specific adjustment method is the same as that in the fifth embodiment and will not be repeated here.

[0040] The vector control hair dryer assembly and its device according to the seventh preferred embodiment of the present invention; the difference from the fifth embodiment is that, as Figures 40 - 41 shown, the second fluid passage 600 and the first fluid passage are in a 90-degree right angle shape. The setting of its adjustment gear is the same as that in the sixth embodiment, and the adjustment of the area size of the second air outlet is the same as that in the fifth embodiment and will not be repeated here.

[0041] Furthermore, as Figures 42 - 43 shown, the blade 605 includes an inner blade 6056 and an outer blade 6057. Both the inner blade and the outer blade enclose a closed loop. The inner blade is placed inside the outer blade. At the same time, the inner blade is placed at the connection of two groups of outer blades to seal the connection gap of the outer blade, and the outer blade is also placed at the connection of two groups of inner blades to seal the connection gap of the inner blade. At this time, the fluid passing through the second air outlet 603 is linear. At this time, only a convex column 6054 is provided on the outer side of the outer blade. After the outer blade is forced to close, it pushes the inner blade to close to reduce the area of the second air outlet. At the same time, elastic part grooves 6055 are provided at the lower ends of both the inner blade and the outer blade. After the thrust of the outer blade disappears, the deformation restoring force of the elastic part pulls the side of the elastic part groove to close, so that the movable end of the blade opens to increase the area of the second air outlet.
