As shown in fig. 1 to 8, an ergonomic hair care appliance comprises a housing assembly 1, wherein an air flow passage is defined in the housing assembly 1, an air flow inlet 2 for air flow to enter is formed in the upstream of the air flow passage, an air flow outlet 3 for air flow to exit is formed in the downstream of the air flow passage, a fan unit 6 for enabling air flow to enter the housing assembly 1 from the air flow inlet 2 is arranged in the housing assembly 1, the housing assembly 1 is in a column shape, the air flow inlet 2 and the air flow outlet 3 are arranged on the housing assembly 1, the air flow outlet 3 is formed in the side wall of the housing assembly 1, the long edge 301 of the air flow outlet 3 is arranged along the height direction of the housing assembly 1, the air flow in the air flow passage flows along the axis direction of the housing assembly 1 before exiting the air flow outlet 3, an air flow reversing element 4 for changing the air flow direction in the air flow passage is further arranged in the housing assembly 1, and the air flow in the air flow passage flows through the air flow reversing element 4 and then exits from the air flow outlet 3.

The technical scheme has the advantages that the shell component 1 of the something worth reading hair care appliance is in a slender column shape in appearance, tends to be concise, has small volume and is convenient to store and carry; the shell component 1 is in a slender column shape, the airflow outlet 3 is arranged on the side wall of the shell component 1, so that the ergonomics are met, accessories for reversing the airflow are not needed, the use is more convenient, and the cost is reduced; the long side 301 of the air flow outlet 3 is arranged along the height direction of the shell component 1, so that the long side 301 of the air flow outlet 3 keeps consistent with the hair growth direction (referring to the structure of a common comb) when in use, blows along the hair growth direction, is beneficial to styling hair, is not easy to mess hair when drying the hair, is convenient to sweep along the hair growth direction in use, and accords with human engineering; the air flow reversing piece 4 is arranged in the shell assembly 1, and the air flow along the axial direction of the shell assembly 1 is blown out from the air flow outlet 3 positioned on the side wall of the shell assembly 1 after being converted, so that the conversion of the air flow direction can be completed without accessories, and the defect that the air flow direction can be converted by the accessories in the prior art to meet the use habit of a user (as mentioned in the background art) is overcome; the hair care appliance in the technical scheme is a complete product, the appearance effect is better than that of the existing product which can be normally used only by connecting accessories, and the matching gaps and lines generated by an unnecessary connecting structure are reduced; the change of the direction of the air flow is realized through the air flow reversing piece 4, so that the loss of air quantity, air pressure and air speed caused by forced direction change of the air flow is avoided; the airflow reversing piece 4 is integrated inside the shell assembly 1, so that the integration of products is higher.

In this example, the shape of the air flow outlet 3 may be a bar, a ring, or a combination of various shapes; when the air flow outlet 3 is annular, the long side refers to the height direction thereof.

In this case, the airflow outlet 3 has one or more, when one, single shape such as strip, or ring; when there are a plurality, the combination of a plurality of strips or a plurality of rings can be a combination of a plurality of shapes.

In this case, the housing assembly 1 has walls whose thickness varies, which facilitates the installation and the fixing of the internal structural components of the housing assembly 1.

The air flow reverser 4 in this example may be a separate component from the housing assembly 1, assembled with the housing assembly 1 by a mechanical connection; members extending from the inner wall of the housing assembly 1, which are part of the housing assembly 1, may also be provided.

After passing through the airflow reversing element 4, the airflow in the airflow passage is blown out from the airflow outlet 3 along a direction deviating from the original moving direction, and the angle deviating from the axis of the housing assembly 1 depends on the position relation between the airflow outlet 3 and the axis of the housing assembly 1. Further, the air flow is discharged from the air flow outlet 3 in a direction substantially perpendicular to the axis A-A' of the housing assembly 1 after the air flow direction change member 4 is acted on. The advantage is that the direction of the air flow outlet 3 arranged on the shell component 1, the shape of the shell component 1, the angle of the air flow discharged from the air flow outlet 3 and the angle of the axis A-A ' of the shell component 1 are possible, and the technical scheme is more in line with the use habit of a user by enabling the air flow to be discharged from the air flow outlet 3 along the direction which is approximately perpendicular to the axis A-A ' of the shell component 1, namely that the air flow outlet 3 is parallel to the axis A-A ' of the shell component 1, the air flow discharged from the air flow outlet 3 can reach the hair surface simultaneously, the ergonomics are in line, and the uniformity of dry hair is improved. In addition, the technical scheme is also beneficial to obtaining the airflow reversing piece 4 with a simple structure, and reduces the structural complexity.

As shown in fig. 2, 6, 7, the airflow diverter 4 directs the airflow to the airflow outlet 3. The air flow is guided by the air flow reversing piece 4 to change the direction, so that the air flow is ensured to be successfully reversed, the air flow reaches the air flow outlet 3 along the preset track and is discharged from the air flow outlet 3, and the air flow diffusion or loss caused by the matching gap between the air flow reversing piece 4 and the air flow outlet 3 can be reduced. Preferably, the airflow reversing element 4 is partially abutted against the inner wall of the housing assembly 1 defining the airflow outlet 3, so that the airflow loss can be reduced to the greatest extent, and the airflow outlet 3 is partially shielded, so that fingers or foreign objects cannot easily touch the internal electrified parts from the airflow outlet 3.

The axis B-B' of the flow reverser 4 is parallel to the long side 301 of the flow outlet 3. The advantage is that the air flow after the action of the air flow reversing element 4 is discharged from the air flow outlet 3 through the shortest distance and the smallest obstruction as far as possible, so that the air flow loss is reduced.

The axis B-B 'of the air flow reverser 4 is parallel to the axis A-A' of the housing assembly 1. The advantage is that on the one hand, the assembly of the airflow reversing piece 4 in the shell assembly 1 is facilitated; on the other hand, it is possible to make the air flow enter the air flow direction changing piece 4 through the shortest path, and the loss generated when the air flow enters the air flow direction changing piece 4 is reduced as much as possible; and the airflow reversing piece 4 can extend in the shell assembly 1 for a sufficient length to slowly reverse the airflow, so that turbulence caused by reversing urgency is reduced.

Further, the airflow reverser 4 and the shell assembly 1 are concentrically arranged, namely the axes of the airflow reverser 4 and the shell assembly 1 are the same, so that on one hand, the assembly of the airflow reverser 4 in the shell assembly 1 is facilitated; on the other hand, the air flow enters the air flow reversing piece 4 through the shortest path, so that the loss generated when the air flow enters the air flow reversing piece 4 is reduced as much as possible; the airflow reversing piece 4 can extend in the shell assembly 1 for a sufficient length to slowly reverse the airflow, so that turbulence generated by reversing urgency is reduced; and make full use of the inner space of the shell assembly 1, make the structure compact, help make the shell assembly 1 have smooth outer surface, can reduce and avoid the unnecessary outer surface to bulge as much as possible.

As shown in fig. 2 to 5 and fig. 7, the airflow direction changing member 4 includes a plurality of direction changing fins 401 for changing the flow direction of the airflow, and the plurality of direction changing fins 401 are arranged at intervals along the long side 301 of the airflow outlet 3. The advantage is that the purpose of changing the direction of the air flow is achieved through the plurality of reversing wings 401, and the structure tends to be simple; because the long side 301 of the airflow outlet 3 is arranged along the height direction of the shell, the arrangement mode of the plurality of reversing fins 401 in the technical scheme is beneficial to discharging as much airflow in the shell assembly 1 from the airflow outlet 3 as possible in unit time, namely, improving the air output in unit time and reducing the complexity of the matching structure of the reversing fins 401 and the airflow outlet 3. In particular, the housing assembly 1 has a columnar shape, the width of the airflow outlet 3 in the present invention is not very large, and if the plurality of direction-changing fins 401 are arranged along the width direction of the airflow outlet 3, it may result in that part of the airflow which is changed by the direction-changing fins 401 cannot be discharged from the airflow outlet 3, resulting in loss of air volume; and may also limit the number of diverter vanes 401 to the desired diverting effect. More specifically, the lateral edges of the direction-changing fin 401 are at an angle to the longitudinal direction of the airflow direction-changing member 4, and preferably the lateral edges of the direction-changing fin 401 are perpendicular to the longitudinal direction of the airflow direction-changing member 4. Further, the transverse edges of the reversing wings 401 cross the width direction of the airflow outlet 3, and a part of the reversing wings abut against the inner wall of the shell assembly 1 defining the airflow outlet 3, and the reversing wings 401 shield the part of the airflow outlet 3, so that internal electrified components can be prevented from being contacted from the airflow outlet 3, and the safety is improved; and the air outlet 3 does not need an air outlet net, so that the structural complexity and the cost of the product are reduced.

The plurality of diverter vanes 401 are viewable from the airflow outlet 3. The advantage is that through the inside electrified components and parts of a plurality of switching-over fins 401 shelter from, make the inside electrified components and parts of casing be the place from the air current export 3 and can not touched, improves the performance of the security of utensil, satisfies the safety requirement.

As shown in fig. 7, the length h2 of the airflow outlet 3 is greater than or equal to the distance h1 between the top of the last diverter vane 401 and the base of the first diverter vane 401. The advantage is that the air flow which is diverted by the reversing vane 401 is ensured to be blown out from the air flow outlet 3, and the air flow is prevented from being blocked by the shell component 1 to generate air flow loss as much as possible. Each of the direction-changing fins 401 has a tendency to extend in the axial direction of the airflow direction-changing member 4 (i.e., the end of the direction-changing fin 401 near the airflow outlet 3 is at a distance from its end near the airflow inlet 2).

The reversing wing 401 is tongue-shaped. Advantageously, the loss of airflow through the diverter vane 401 is reduced, allowing airflow to exit the airflow outlet 3 along the drag of the surface of the diverter vane 401. The surface of the reversing vane 401 facing the air flow inlet 3 is smooth, and the surface is the surface through which the air flow passes, so that the loss generated when the air flow passes the reversing vane 401 can be reduced.

The airflow reverser 4 further comprises a connector 402, the connector 402 connecting the plurality of reverser fins 401 in a direction parallel to the axis of the airflow reverser 4. The air flow reversing element 4 is made to be a single piece, so that the air flow reversing element 4 is convenient to install in the shell assembly 1, and the obstruction factor to air flow caused by assembly errors is reduced. The connecting piece 402 may be connected to the end of the diverter vane 401 near the air inlet 2, and the other end is suspended, or may be connected to the middle of the adjacent diverter vane 401. Or other means of connecting the plurality of diverter vanes 401.

When the connection pieces 402 are each connected to the end of the direction-changing fin 401 near the airflow inlet 2, the airflow passing through the airflow direction-changing piece 4 is divided into N airflows, n=the number of direction-changing fins 401.

When the connectors 402 are each connected to the middle portion of an adjacent direction-changing fin 401, the air flow passing through the air flow direction-changing member 4 is divided into N air flows, n=the number of direction-changing fins 401×2 or n=the number of direction-changing fins 401.

The number of N depends on how the connector 402 mates with the diverter blade 401. When the connector 402 extends laterally to the end of the diverter vane 402 near the airflow outlet 3, then n=the number of diverter vanes 401 is 2; when there is a certain gap between the end of the diverter vane 401 near the airflow outlet 3 and the longitudinal end face of the connector 402, at this time, n=the number of the diverter vanes 401, that is, the number of airflow streams passing through the airflow diverter 4, there is a process in which the number of diverter vanes 401 is changed from 2 x to the number of diverter vanes 401, and mixing is performed at the aforementioned gap.

There are three cases where n=1, n=number of the direction-changing fins 401, and n=number of the direction-changing fins 2, for the number of independent air streams discharged from the air stream outlet 3. When n=1, the end of the reversing vane 401 near the airflow outlet 3 has a certain gap with the side wall defining the airflow outlet 3, and a certain gap exists between the longitudinal end surface of the connecting piece 402 and the airflow outlet 3, where n=the number of reversing vanes 401 or n=the number of reversing vanes 401×2; when n=the number of the direction-changing fins 401, the air flow passing through the air-flow direction-changing member 4 is divided into n=the number of the direction-changing fins 401 and the end of the direction-changing fins 401 near the air-flow outlet 3 abuts against the side wall defining the air-flow outlet 3; when n=the number of the direction-changing fins 2, the airflow passing through the airflow direction-changing member 4 is divided into n=the number of the direction-changing fins 401 x2, and the end of the direction-changing fin 401 near the airflow outlet 3 abuts against the side wall defining the airflow outlet 3, and the connecting member 402 extends to the airflow outlet 3 (i.e., the longitudinal end face of the connecting member 402 is located on the same plane as the airflow outlet 3). The connecting piece 402 is a baffle, and the plurality of reversing fins 401 are respectively arranged at two sides of the baffle. The air flow reversing device has the advantages that the baffle can pull air flow, the air flow passing through the air flow reversing piece 4 is pulled by at least two surfaces of the air flow reversing piece, and the air flow reversing device is beneficial to guiding and changing the direction of the air flow and gathering of the air flow; the baffle can increase the contact area between the reversing wing pieces 401 and the reversing wing pieces, so that the connection strength between the reversing wing pieces 401 and the reversing wing pieces can be improved, the airflow reversing piece 4 is not easy to deform, and the influence of the deformation of the airflow reversing piece 4 on the airflow parameters is reduced.

A heating element 5 for heating the air flow in the air flow path is also provided in the housing assembly 1, the heating element 5 being parallel to the axis B-B' of the air flow reversing element 4. Through the setting of heating element 5, the air current that makes from air current export 3 blowout is the hot air current, and the quick stoving hair of being convenient for, and because the casing subassembly 1 in this technical scheme is long and thin column, how reasonable the positional relationship of each spare part in the casing just can reach first stated design requirement, make heating element 5 and the axis parallel of air current switching-over piece 4, can make full use of the inner space of casing subassembly 1, obtain the hair care implement of compact design, small, loss when can reduce the air current in the air current passageway through each part of arranging in casing subassembly 1 again.

In this case, the downstream of the heating assembly 5 is abutted against at least the bottom end of one of the reversing fins 401, so that the air flow flowing out of the heating assembly 5 passes directly through the reversing fins 4, and the air flow loss is reduced. It will be appreciated that the downstream of the heating assembly 5 may be against the bottom ends of all of the diverter fins 401.

In this example, the heating element 5 is spaced from the fan unit 6 by a distance that prevents the fan unit 6 from being damaged by the radiant heat generated by the heating element 5.

Preferably, the heating assembly 5 is arranged concentrically with the air flow reversing element 4, i.e. the axes of the two are the same; the loss of the air flow in the air flow path through the components arranged in the housing assembly 1 is reduced as much as possible, while a more compact structural layout is obtained, which is able to overcome as much as possible undesired bulges, bulges at the outer surface of the housing assembly 1.

Further preferably, the air flow reverser 4 is arranged concentrically with the housing assembly 1, i.e. with the same axis; the housing assembly 1 defines an airflow passage, in this example, the airflow reversing member 4, the heating assembly 5 and the housing assembly 1 are concentrically arranged, so that on one hand, loss of airflow in the airflow passage when passing through all components arranged in the housing assembly 1 is reduced as much as possible, and meanwhile, a more compact structural layout is obtained, and undesirable bulges and bulges on the outer surface of the housing assembly 1 can be overcome as much as possible.

Further preferably, the fan unit 6 is arranged concentrically with the air deflector 4, i.e. with the same axis. When other parts parallel to the axis of the heating assembly 5 are also arranged in the shell assembly 1, the arrangement of the parts can make full use of the space in the shell assembly 1 by the technical scheme, and the undesirable bulges and bulges on the outer surface of the shell assembly 1 due to the arrangement of the parts are overcome.

In this case, the heating assembly 5 is located upstream of the flow reverser 4. The air flow is heated after passing through the heating component 5 and then is discharged from the air flow outlet 3 through the air flow reversing piece 4, so that the heated air flow has a section of air flow which exchanges heat with cold air before passing through the air flow outlet 3, and hot spots can be effectively reduced.

The fan unit 6 is located upstream of the heating assembly 5. The fan unit 6 comprises a motor and fan blades, and the scheme ensures that cold air flows firstly pass through the fan unit 6 and then pass through the heating component 5, so that the motor is prevented from being damaged due to hot air flow.

The airflow reversing element 4 comprises an axial guiding section for guiding the airflow to move along the axial direction of the airflow reversing element, and a reversing section for changing the moving direction of the airflow, wherein the reversing section extends to the airflow outlet 3. By allowing the air flow to reach the air flow outlet 3 along a predetermined trajectory and to be discharged from the air flow outlet 3, the diffusion or loss of the air flow caused by the fit gap between the air flow direction changing member 4 and the air flow outlet 3 can be reduced.

As shown in fig. 8, the airflow reversing element 4 further includes a cylinder 403, where the cylinder 403 is connected to the plurality of reversing fins 401, so as to improve the strength of the airflow reversing element 4, make the airflow reversing element 4 not easy to deform, and reduce the influence of deformation of the airflow reversing element 4 on airflow parameters; the heating component 5 is located at the upstream of the airflow reversing component 4, the airflow is heated after passing through the heating component 5, and then is discharged from the airflow outlet 3 through the airflow reversing component 4, so that the heated airflow has a section of airflow which exchanges heat with cold air before passing through the airflow outlet 3, and hot spots can be effectively reduced.

The heating element 5 extends partially into the cylinder 403. On the one hand, the air flow passing through the heating component 5 completely enters the cylinder 403, and the cylinder 403 gathers and rectifies the air flow, so that the gathered air flow can pass through the reversing wing pieces 401, and the reversing wing pieces 401 are convenient for rectifying and reversing the air flow; on the other hand, the outer peripheral wall of the cylinder 403 forms the positioning when it is mounted in the housing assembly 1, improving the mounting reliability of the airflow reverser 4; third, the heating component 5 and the airflow reversing piece 4 are formed into a component, and then are installed in the shell component 1, so that the assembly convenience is improved, the heating component 5 and the airflow reversing piece 4 mutually apply axial force to the other party, and the assembly reliability is improved.

The axial flow guide section in this example includes a barrel 403 portion, and a first section 404 of the plurality of diverter vanes 401; the turn section includes a second section 404 of the plurality of diverter vanes 401.

Example 2:

The present example generally describes an airflow reversing element 4 for mounting within a hair care appliance to alter the direction of airflow within the appliance, as described in detail below.

As shown in fig. 3 to 5, an airflow reversing element 4 comprises a plurality of reversing wings 401 for guiding airflow and changing the flowing direction of the airflow, and a connecting piece 402 for connecting the reversing wings 401, wherein the reversing wings 401 are arranged at intervals along the longitudinal axis direction of the reversing wings, and the flow velocity of the airflow before passing through the airflow reversing element 4 is larger than the flow velocity after reversing. The air flow reversing piece has the advantages that the reversing pieces 401 are connected through the connecting piece 402, the reversing pieces 401 and the connecting piece 402 are integrated, the installation of the air flow reversing piece 4 is facilitated, the structure is more reliable and stable, and deformation is not easy to occur; the plurality of reversing fins 401 are arranged at intervals along the longitudinal axis direction of the reversing fins, so that a plurality of independent air flows distributed along the longitudinal axis direction of the reversing fins can be obtained, and the air flows are rectified; the airflow speed is reduced through the airflow reversing piece 4, so that the wind pressure suitable for the habit of a user is obtained, and the pressure is reduced to be too large, so that the user has a sense of compression in use.

Further, the flow velocity of the air flow before passing through the air flow reversing element 4 is larger than the flow velocity after reversing. The airflow speed is reduced through the airflow reversing piece 4, so that the wind pressure suitable for the habit of a user is obtained, and the pressure is reduced to be too large, so that the user has a sense of compression in use.

The connector 402 connects the plurality of diverter fins 401 in a direction parallel to the axis of the airflow diverter 4. The air flow direction guiding device has the advantages that the direction of the axis is guided, and the direction of the air flow net offset axis is guided through the reversing wing pieces 401, so that the purpose of reversing the air flow is achieved; the wind resistance is reduced, and the air flow loss is reduced.

The air flow is divided into a number of air flows equal to at least the plurality of direction-changing fins 401. The advantage is that, in this technical scheme, connecting piece 402 locates the one end of switching-over fin 401, and the air current is pulled by switching-over fin 401 and is formed the multistrand air current, carries out the rectification to the air current.

The air flow is divided into a plurality of air flows with the number of the reversing wings 401 being greater than or equal to the number of the reversing wings 401 under the action of the reversing wings 401 and the connecting piece 402. The advantage is that, in this technical scheme, at least part of connecting piece 402 is close to the middle part setting of switching-over fin 401, and the air current separates into a plurality of air currents under the effect of switching-over fin 401 and connecting piece 402, carries out the rectification to the air current. Specific examples have been described in detail in embodiment 1, and are not described here again.

The reversing vane 401 includes a first section 404 for guiding the air flow to move in the axial direction thereof, and a second section 405 for changing the direction of the air flow, and the first section 404 is smoothly connected with the second section 405. The device has the advantages that the airflow is slowly changed, and the airflow loss caused by turbulence generated by over-sharp airflow turning is reduced.

The second section 405 is arcuate. The air flow reversing device has the advantages that the wind resistance of the reversing wings 401 to the air flow is reduced, the loss of the air flow is reduced, and the slow direction change of the air flow is realized.

The plurality of diverter vanes 401 are identical in shape. The air flow direction control device has the advantages that multiple air flows which are reversed by the reversing fins 401 are ensured to be in approximately the same direction and angle, and vortex caused by different directions of the multiple air flows is avoided, so that air quantity and wind pressure are lost.

The number of the reversing wings 401 is M, and M is more than or equal to 2 and less than or equal to 10. The device has the advantages that the reversing can be realized, the air flow can be rectified, and the great air flow loss can not be caused; when M is smaller than 2, when the air flow is larger, all the air flows in the vertical direction with larger wind force directly impact on the reversing wing pieces 401, and partial air flows are forced to be reversed, so that the air flow is lost; when M > 10, the number of the reversing fins 401 is excessive, firstly, the structural complexity is increased, the cost is increased, and secondly, when the air flow is separated by a plurality of reversing fins 401, wind resistance exists, and the excessive reversing fins 401 also cause the loss of air flow. Preferably m=4.

The plurality of diverter vanes 401 have approximately the same effect on the angle of the airflow change. The advantage is that the directions of the multiple airflows separated by the multiple reversing fins 401 are approximately the same when the airflows leave from the airflow reversing piece 4, so that the loss of air quantity, air pressure or air quantity and air pressure caused by collision among the multiple airflows when the directions of the multiple airflows leave are different is avoided.

When other parts parallel to the axis of the heating assembly 5 are also arranged in the shell assembly 1, the arrangement of the parts can make full use of the space in the shell assembly 1 by the technical scheme, and the undesirable bulges and bulges on the outer surface of the shell assembly 1 due to the arrangement of the parts are overcome.
