The following describes the present invention in detail with reference to the accompanying drawings.

As shown in fig. 1, an air flow multiplying 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 arranged at the upstream of the air flow passage, an air flow outlet 3 for air flow to exit is arranged at the downstream of the air flow passage, a fan unit for enabling the air flow to enter from the air flow inlet 2 to the interior of the housing assembly 1 is arranged in the housing assembly 1, the housing assembly 1 is in a columnar shape, the air flow inlet 2 and the air flow outlet 3 are both arranged on the housing assembly 1, and the air flow outlet 3 is in an elongated shape.

The shell component 1 of the 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; because the airflow outlet 3 is in a slender shape, an air net does not need to be arranged, the internal structural member can not be touched by hands, and the safety requirement is met; the air flow outlet 3 in the slender shape is beneficial to increasing air pressure and flow speed, and the rapidly flowing air flow can drive surrounding air flow to flow, so that the increase of air volume reaching the surface of hair is realized, namely, the air flow is multiplied, and the hair is rapidly dried and shaped; in addition, the air flow outlet 3 with a slender shape overcomes the defect that the air flow can be rectified only by adding accessories matched with the main body in the products on the market. Through the combination of two designs of slender cylindrical shell component 1 and airflow inlet 2, the whole design of the hair care appliance is easy to be simple, the airflow multiplication can be realized, and the defects of small volume and small air pressure of a blower are overcome.

The elongated shape includes a strip shape having a length much larger than a width, or a ring shape, and a height direction (i.e., a longer side) of the air flow outlet 3 is kept coincident with a height direction of the housing assembly 1. The hair dryer has the advantages that the hair dryer accords with human engineering, when a user uses the hair dryer to dry or shape hair, the long edge of the airflow outlet 3 is consistent with the hair growth direction and blows along the hair growth direction, so that the hair dryer is beneficial to hair shaping, and the hair is not easy to mess when being dried; and the hair brush is convenient to sweep along the growth direction of the hair in the using process, and accords with the using habit of a user. In addition, this is advantageous for obtaining an optimal design of the airflow outlet 3 without using an air outlet net and without touching the internal structural members from the airflow outlet, and also for obtaining an ideal airflow outlet 3 area.

As shown in fig. 1 and 2, the airflow outlet 3 is provided on a side wall of the housing assembly 1, and the airflow passes through the airflow passage and blows out from the airflow inlet 2 for at least one reversing. The shell component 1 is in a slender column shape, the side wall of the shell component 1, provided with the airflow outlet 3, accords with human engineering, does not need accessories for reversing airflow, is more convenient to use, and reduces cost. In this case, the airflow inlet 2 may be disposed on a side wall of the housing assembly 1, or may be disposed on a bottom wall of the housing assembly 1, or the airflow inlet 2 may be distributed on the side wall and the bottom wall of the housing assembly 1.

Further, the airflow outlet 3 is parallel to the axis of the housing assembly 1. The air flow discharged from the air flow outlet 3 can reach the hair surface at the same time, which is beneficial to improving the uniformity of the dried hair. More specifically, the airflow outlet 3 is parallel to the axis of the housing assembly 1 in the height direction thereof.

The airflow outlet 3 is oriented substantially parallel to the direction of airflow at the airflow inlet 2, which airflow is reversed twice when exiting the airflow outlet 3. The technical scheme enables the airflow inlet 2 to be arranged on the side wall of the shell component 1, which is beneficial to increasing the air inlet area and further increasing the air quantity; the air flow enters the interior of the shell assembly 1 from the air flow inlet 2 in a direction substantially perpendicular to the axis of the shell assembly 1, then extends in the axial direction of the shell assembly 1, then changes and then exits from the air flow outlet 3 in a direction substantially perpendicular to the axis of the shell assembly 1, and undergoes two reversals, and is ergonomic. The air quantity can be increased and the ergonomics can be satisfied by combining the two, an accessory for reversing the air flow is not needed, the use is more convenient, and the cost is also reduced.

As shown in fig. 3, the air flow discharged from the air flow outlet 3 forms an inner air flow bundle 4, the inner air flow bundle 4 draws the air flow outside the housing assembly 1 to flow along the outer surface of the housing assembly 1 to form an outer air flow bundle 5 when discharged from the air flow outlet 3, and the inner air flow bundle 4 cooperates with the outer air flow bundle 5 to reach the hair surface. According to the coanda effect, the high-speed airflow discharged from the elongated airflow outlet 3 drives the airflow on the outer surface of the shell component 1 to form an external airflow bundle 5, so that the purpose of increasing the air volume is achieved.

The inner gas stream 4 is separate from the outer gas stream 5. The external air flow beam 5 is the same as the ambient temperature, while the internal air flow beam 4 is generally higher than the ambient temperature, especially when a heating component is arranged in the shell component 1, the temperature of the internal air flow beam reaches above 90 ℃, so that hot spots are easy to generate, and the hair can be prevented from being damaged by the over-high temperature air flow by enabling the two air flows with different temperatures to reach the surface of the hair; and the wind pressure of the inner air flow beams 4 is greater than that of the outer air flow beams 5, so that different acting forces are applied to the scalp to form pressure difference, and a massage effect is achieved.

The inner air stream 4 is mixed with the outer air stream 5 to reach the surface of the hair. The outer air flow beam 5 is the air flow with the same temperature as the ambient temperature, the inner air flow beam 4 is the air flow with the temperature higher than the ambient temperature generally, and the temperature of the air flow reaching the surface of the hair can be reduced after the two air flows of the inner air flow beam 4 and the outer air flow beam 5 are mixed, so that hot spots are reduced, and the hair is prevented from being damaged by the air flow with the overhigh temperature.

As shown in fig. 4, the housing assembly 1 has a guide 6 for guiding the outer air stream 5, the guide 6 being part of an outer surface of the housing assembly 1 that is accessible to a user. By arranging the guide part 6, the external air flow beams 5 flow along a preset track, so that the direction of the external air flow beams 5 can be controlled, the matching mode of the external air flow beams 5 and the internal air flow beams 4 can be controlled, and the aims of increasing the air volume and reducing hot spots are fulfilled.

The included angle between the guide part 6 and the transverse axis of the airflow outlet 3 is alpha, and alpha is more than or equal to 10 degrees and less than or equal to 80 degrees. Within the range of the included angle, an external gas flow beam 5 can be formed under the action of the internal gas flow beam 4; when alpha is less than 10 degrees or alpha is more than 80 degrees, the external airflow 5 can not be generated by the coanda effect, and the aim of increasing the air volume can not be achieved. Preferably α =20 °.

The guide 6 has at least two and is located at the side of the housing assembly 1 to form the outer gas stream 5 on both sides of the inner gas stream 4. The outer airflow stream 5 is formed by the side traction of the shell assembly 1, and the surface area of the side surface of the shell assembly 1 is larger, so that the larger outer airflow stream 5 is formed, and the larger air volume is obtained. More specifically, the guiding portion 6 is a surface of the housing assembly 1, and the surface may be a curved surface or a plurality of flat surfaces connected to each other. In this example, the guide portion 6 is formed by connecting a plurality of curved surfaces, the cross section of the housing assembly 1 is approximately rounded, the guide portion 6 is formed by two curved surfaces with different curvatures, namely a first curved surface 601 and a second curved surface 602, and the curvature of the first curved surface 601 near the airflow outlet 3 is larger than that of the second curved surface 602 far away from the airflow outlet 3. When the airflow in the airflow passage is discharged from the airflow outlet 603, the airflow in the external environment is driven to move along the guide of the second curved surface 602, and then gradually approaches the internal airflow bundle 4 along the guide of the first curved surface 601, so that the effect of airflow multiplication, that is, the effect of air volume multiplication, is achieved. Different return paths of the air flow motion of the outer air flow beams 5 can be obtained by adjusting the curvature of the first curved surface 601 and the second curved surface 602, so that whether the inner air flow beams 4 and the outer air flow beams 5 are parallel or reach the surface of hair after being mixed is realized. In this example, α is an acute angle formed by a tangent line at the junction of the first curved surface 601 and the second curved surface 602 and the axis of the airflow outlet 3.

It is understood that the guide portion 6 is formed by connecting a plurality of flat surfaces, and more specifically, the first curved surface 601 and the second curved surface 602 in the above example are changed into the first flat surface 601 and the second flat surface 602, the first flat surface 601 and the second flat surface 602 are connected, and the acute angle formed by the second flat surface 602 and the axis of the air flow port 3 is α.

It will be appreciated that the guide portion 6 is formed by connecting flat and curved surfaces. The plane and the curved surface are in smooth transition at the joint. For example, the guide portion 6 may be formed by the first curved surface 601 and the second flat surface 602, in which case the acute angle formed by the second flat surface 602 and the axis of the airflow port 3 is α; the guide portion 6 may be formed by the second curved surface 602 and the first plane 601, and in this case, an acute angle α formed by a tangent line at a connection point of the second curved surface 602 and the first plane 601 and an axis of the airflow outlet 3 is defined.

The airflow outlet 3 is located on the same surface as an operating surface accessible to a user of the housing assembly 1. Firstly, the appearance consistency is better and more concise; secondly, the air outlet 3 is made as close as possible to the user-accessible operating surface, which, according to the coanda effect, is advantageous in that more air flows in the external environment follow the air flow discharged from the air outlet 3, so that the aim of increasing the amount of air flow reaching the hair surface of the user is achieved.

As shown in FIG. 2, the ratio of the length of the airflow outlet 3 to the width thereof is S1, and 7 & ltS 1 & lt36 & gt. The air pressure is increased, the flow rate is increased, the fast flowing air flow can drive the surrounding air flow to flow, the increase of the air quantity reaching the surface of the hair is realized, namely, the air flow is multiplied, so that the hair is dried fast, and the hair is shaped; by changing the shape and parameters of the airflow outlet 3, the hair care appliance in the technical scheme is not required to be matched with any accessory for practical use, and can also rectify the airflow to achieve the purpose of shaping the hair, thereby saving the process of assembling the accessory by a user and simplifying the operation steps; and need not install the air net, interior structure can not touched by the hand yet, satisfies the ann rule requirement. When S1 is less than 7, when the width of the airflow outlet 3 is larger, an air outlet net is needed to be arranged so that the internal structural part can not be touched by hands, the structural complexity is increased, the assembly steps are increased, and the cost is increased; when the airflow outlet 3 is too short, the air exhaust efficiency of the air outlet is reduced, so that the air output is reduced, the hair drying efficiency is reduced, and the styling effect is poor; when S1 is more than 36, the length of the whole machine is lengthened when the airflow outlet 3 is too long, and some safety problems are caused by the exposure of internal structural components if the whole machine is not lengthened; when 3 short-term air outlets, the efficiency of airing exhaust of air outlet reduces, can make the air output diminish, and then leads to hair drying efficiency to reduce, and the molding effect variation. In this example, S1=14.2 is preferable.

The ratio of the length of the airflow outlet 3 to the length of the shell assembly 1 is S2, and S2 is not less than 1/2 and not more than 1/30. The internal parts of the shell component 1 are compactly arranged, large air volume can be obtained, and the shell component 1 is suitable in length and convenient to carry and store. When S1 is less than 1/30, the length (longitudinal distance) of the airflow outlet 3 is too short, so that the width of the air outlet is large to obtain large air volume, the appearance is not attractive enough, and the internal structural parts are easy to contact and are unsafe; if the width is proper, the area of the air outlet is too small, the air output per unit time is small, and the hair drying efficiency is low; when S1 is greater than 1/2, the length of the airflow outlet 3 is too long, internal structural parts are easy to contact and are unsafe, and if the length of the airflow outlet 3 is proper, the length of the shell assembly 1 is increased, and the problem of occupying more storage space is caused. Preferably S2= 0.25.

The ratio of the width of the airflow outlet 3 to the width of the shell assembly 1 is S3, and S3 is more than or equal to 0.05 and less than or equal to 0.75. The air quantity is increased, and meanwhile, the internal structure is not easy to touch, so that the safety requirement is met. When S3 is less than 0.05, the width of the airflow outlet 3 is too small, and the air outlet efficiency is influenced; when S3 > 0.75, airflow outlet 3 width is too big, can lead to the loss of wind pressure on the one hand, and on the other hand, do not adorn the net of wind and make the inner structure touch easily, adorn the net of wind and can make the structure complexity improve, the cost improves. Preferably S3= 0.115.

The aforementioned airflow outlet has a length of L1, an airflow outlet width of D1, an airflow housing assembly length of L2, and a housing assembly width of D2. In the utility model, L1 is 71mm, D1 is 4.6 mm; and L2-289 mm and D2-40 mm. The width of the housing assembly 1 is meant to coincide with the width direction of the airflow outlet 3 (see figure).

The ratio of the area of the airflow outlet 3 to the area of the airflow inlet 2 is S4, and S4 is more than or equal to 0.6 and less than or equal to 1. Airflow enters into the balance air inlet volume and air outlet volume, air volume loss is reduced, and the power of the motor is reasonably selected; when the area of the airflow outlet 3 is too small when the S4 is less than 0.6, more airflow cannot be discharged from the airflow outlet 3 in time, so that the airflow is accumulated in the shell assembly 1 to generate airflow loss; when S4 > 1, the airflow outlet 3 has an excessively large area, and the airflow blown out from the airflow outlet 3 is relatively dispersed and not concentrated. Preferably S4= 0.8.

The airflow outlet 3 is provided with a plurality of spaced and parallel distribution. Through the setting of a plurality of linear airflow outlets 3, original wind pressure and wind speed can be guaranteed while the air quantity is improved.

A partition is arranged between two adjacent airflow outlets 3, and the width of the partition is smaller than that of the airflow outlets 3. The plurality of air flow outlets 3 are arranged compactly, so that the size of the housing assembly 1 can be made appropriate, and the volume of the hair care appliance can be made small.

The number of the airflow outlets 3 is N, and N is more than or equal to 1 and less than or equal to 4. The volume of the hair care appliance can be reduced while the air volume is increased; when N > 4, the volume of the housing assembly 1 is increased. Preferably N = 2.

The flow rate of the air flow discharged from the air flow outlet 3 is greater than the flow rate of the air flow entering from the air flow inlet 2. The noise of the air flow entering the housing assembly 1 from the air flow inlet 2 is reduced, and the air flow blown out from the air flow outlet 3 can achieve a good effect in styling the hair.

The above embodiments are merely preferred embodiments of the present invention, not all embodiments of the present invention, and according to the principles of the present invention, those skilled in the art can make various modifications without departing from the spirit of the present invention, all of which shall fall within the scope of the present invention defined by the claims.
