[0002] At present, hair dryers are composed of a set of electric heating wires and a small high-speed fan. When powered on, the electric heating wires will generate heat, and the wind blown by the fan will become hot air when it passes through the electric heating wires. If only the fan rotates but the electric heating wires are not hot, the wind will only be blown out.

[0003] The hair dryer includes an outer shell and an inner shell. The outer shell is the outside that is observed by people, and the inner shell is located inside the outer shell. The heating wire and the small fan are located inside the outer shell. According to the design requirements, some inner shells need to lay out wires on the outside of the inner shell. This type of hair dryer has a loss in the air volume blown out from the air outlet. Utility Model Content

[0039] As part of the creative concept of the present application, before describing the embodiments of the present application, it is necessary to analyze the causes of the problem of air volume loss in the hair dryer in the related art, and obtain the technical solution of the embodiments of the present application through reasonable analysis.

[0040] In the related art, the main function of a hair dryer is to provide body care for users. The hair dryer blows out hot air, normal temperature air, and hot and cold cycle air according to the needs of users to achieve hair drying and hair styling. In this embodiment, the hair dryer is mainly used in daily home life scenes to meet people's daily hair care needs; in other embodiments, the hair dryer can also be used in other scenes such as laboratories and factories as needed.

[0041] The hair dryer includes a body, a fan unit, a heating unit and a control unit. The body includes an air inlet and an air outlet. The fan unit is used to drive the gas from the air inlet into the inner cavity of the body and out of the body from the air outlet. The heating unit can be used to heat the gas flowing through the inner cavity of the body. The control unit is used to control the operation of the hair dryer.

[0042] The heating unit includes a mica sheet and a heating wire, and the heating wire is wound on the mica sheet. The mica sheet is used for supporting, and the heating wire is used for generating heat.

[0043] The hair dryer includes an inner shell and an outer shell. The inner shell is located in the inner cavity of the outer shell. The heating unit and the fan unit are both arranged in the inner shell. Air enters through the air inlet of the outer shell, flows in the inner cavity of the inner shell, and finally flows out from the air outlet of the outer shell.

[0044] The hair dryer in this embodiment has a secondary heating component in the inner cavity, including but not limited to a round brush and a curling iron. The secondary heating component needs to be electrically connected to other parts of the hair dryer through a wire to realize power supply and control of the secondary heating component.

[0045] The wires connected to the secondary heating assembly include power supply wires and control signal wires. The side wall of the inner shell is provided with holes, and the wires need to be penetrated through the holes before they can be electrically connected to the secondary heating assembly. The holes provided on the side wall of the inner shell for the wires to pass through will cause air leakage in the hair dryer, resulting in a loss of air volume in the hair dryer.

[0046] To this end, the present application provides a hair dryer, comprising an inner shell, a wire and a seal; wherein the inner cavity of the inner shell has a ventilation channel, and a first hole is provided on the side wall of the inner shell; a part of the wire is arranged on the outside of the inner shell, and the other part passes through the first hole and is located in the inner cavity of the inner shell; the seal covers part of the first hole, and the seal avoids the wire, thereby solving the technical problem of air volume loss in the hair dryer in the prior art in which the wire is arranged on the outside of the inner shell.

[0047] The technical solutions of the embodiments of the present application are described in detail below in conjunction with the accompanying drawings. The technical features involved in the different implementation modes of the present application described below can be combined with each other as long as there is no conflict between them.

[0048] For ease of explanation, a first direction is defined, which is the direction in which the gas flows from the air inlet to the air outlet, without considering the flow of the gas along the radial direction of the inner shell. In the drawings, the first direction is indicated as the X direction.

[0049] The present application embodiment discloses a hair dryer. Figure 1 and Figure 2 The hair dryer includes an inner shell 3, a wire 2 and a seal 1; wherein the inner cavity of the inner shell 3 has a ventilation channel, and a first hole 31 is provided on the side wall of the inner shell 3; a part of the wire 2 is arranged on the outer side of the inner shell 3, and the other part passes through the first hole 31 and is located in the inner cavity of the inner shell 3; the seal 1 covers part of the first hole 31, and the seal 1 avoids the wire 2.

[0050] Exemplarily, the hair dryer also includes a housing 9, the housing 9 is attached Figure 1 It is only schematically shown in the figure, and the inner shell 3 is fixed in the inner cavity of the outer shell 9. The inner shell 3 and the outer shell 9 can be fixedly connected by one or more methods such as snaps, bolts, and glue.

[0051] When the hair dryer is working, air enters from the air inlet of the outer shell 9, flows in the inner cavity of the inner shell 3, and finally flows out from the air outlet. Generally, the air flowing in the inner shell 3 is the effective air that finally flows out from the air outlet, and the air flowing between the inner shell 3 and the outer shell 9 should be minimized.

[0052] In the present embodiment, a secondary heating component 8 is provided inside the hair dryer. The secondary heating component 8 is electrically connected to the power supply of the circuit via the wire 2 , and is also signal-connected to the circuit board that controls the secondary heating component 8 via the wire 2 .

[0053] Since the wire 2 disposed in the inner cavity of the inner shell 3 will have a certain impact on the airflow, arranging the wire 2 outside the inner shell 3 as much as possible can reduce the impact of the wire 2 on the airflow. In this embodiment, a part of the wire 2 is arranged outside the inner shell 3.

[0054] The first hole 31 provided on the inner shell 3 is used for the wire 2 to pass through. The wire 2 includes a plurality of wire harnesses. The specification of the first hole 31 is determined according to the specification, quantity and arrangement requirements of the cables. At the same time, the setting of the first hole 31 also needs to consider the structural requirements and molding requirements of the inner shell 3 and the assembly requirements of the wire 2. In this embodiment, the first hole 31 is a rectangular hole provided on the side wall of the inner shell 3. The length of the first hole 31 is along the first direction, and the width is along the circumferential direction of the inner shell 3.

[0055] The seal 1 covers part of the first hole 31, and the seal 1 avoids the wire 2. The seal 1 only needs to cover the first hole 31. The seal 1 can be completely embedded in the first hole 31, or partially located outside the first hole 31. In the present embodiment, the seal 1 is completely embedded in the first hole 31. The material of the seal 1 is determined according to the design requirements, and preferably made of insulating, weather-resistant and high-temperature resistant materials. Except for the part of the seal 1 that avoids the wire 2, the rest of the seal should be as close to the side wall of the first hole 31 as possible to reduce the amount of air leakage. Specifically, the seal 1 is a rectangular plate with a certain elasticity, and a avoidance groove is provided on the seal 1, and the avoidance groove accommodates the wire 2.

[0056] The existence of the first hole 31 can realize the design requirement of the wire 2 passing through the side wall of the inner shell 3. The specification of the first hole 31 should meet the assembly requirements of the wire 2 and facilitate the installation of the wire 2. Therefore, the specification of the first hole 31 is larger than the sum of the cross-sections of the wires 2. The larger the cross-section of the first hole 31, the easier it is for the air in the inner cavity of the inner shell 3 to flow out from the first hole 31.

[0057] After the wire 2 passes through the first hole 31 and is arranged at a set position, the seal 1 is used to block the first hole 31 , thereby reducing the leakage of gas in the inner shell 3 from the first hole 31 and allowing more air to flow in the inner cavity of the inner shell 3 .

[0058] The sealing member 1 can also constrain the wire 2 , reduce the movement of the wire 2 relative to the inner shell 3 , and keep the position of the wire 2 on the inner shell 3 stable.

[0059] Reference Figure 2 As an optional solution, the wire 2 includes a first wire 21 and a second wire 22 having different functions.

[0060] The sealing member 1 is provided with two avoidance grooves, which correspond to the first conductive wire 21 and the second conductive wire 22 one by one.

[0061] Exemplarily, the first wire 21 and the second wire 22 have different functions, and the types, colors, and currents flowing through the first wire 21 and the second wire 22 are different. The first wire 21 and the second wire 22 are divided into certain areas to facilitate assembly of the wire 2.

[0062] The number of the avoidance slots is determined according to design requirements. In this embodiment, two avoidance slots are provided. In another embodiment, the number of the avoidance slots may be three, four or other numbers.

[0063] It should be noted that the number of avoidance grooves does not necessarily have to correspond one-to-one to the wires 2 with different functions, and wires 2 with the same function can also be arranged in different avoidance grooves.

[0064] In this embodiment, the first conductor 21 and the second conductor 22 are arranged in one-to-one correspondence with the two avoidance grooves, which can facilitate the assembly, quality inspection and subsequent maintenance of the conductors 2 with the same function.

[0065] Further, the two avoidance grooves are arranged at intervals along the first direction, and the two avoidance grooves are two notches arranged on the same side of the avoidance groove. Exemplarily, the shape of the notch is square. At this time, the structure of the sealing member 1 is similar to an E-shaped plate.

[0066] The first wire 21 and the second wire 22 have different functions. The farther the distance between the first wire 21 and the second wire 22 located in the two avoidance slots is, the smaller the electromagnetic interference between the first wire 21 and the second wire 22 is.

[0067] Reference Figure 2 As an optional solution, the first wire 21 is a control signal wire, and the second wire 22 is a power supply wire; the wire 2 also includes a third wire 23, and the function of the third wire 23 is different from that of the first wire 21 and the second wire 22.

[0068] Exemplarily, the third wire 23 in this embodiment is used to be conductively connected to the heating unit and to supply power to the heating unit. In this embodiment, the third wire 23 and the second wire 22 are located in the same avoidance groove.

[0069] The conductor 2 includes conductors 2 with at least two functions. In this embodiment, the conductor 2 includes conductors 2 with three functions. In another embodiment, the conductor 2 may further include conductors 2 with other functions.

[0070] Reference Figure 1 As an optional solution, a secondary heating component 8 is also included, and the first wire 21 and the second wire 22 are electrically connected to the secondary heating component 8.

[0071] For example, the secondary heating component 8 includes but is not limited to at least one of a round brush and a curling iron. The specific function of the secondary heating component 8 is determined according to design requirements. In this embodiment, the secondary heating component 8 is located in the inner cavity of the inner shell 3 as an example for explanation.

[0072] The current flowing through the first wire 21 is greater than the current flowing through the second wire 22. The first wire 21 is electrically connected to the secondary heating assembly 8 for supplying power to the secondary heating assembly 8; the second wire 22 is electrically connected to the secondary heating assembly 8 for controlling the operation of the secondary heating assembly 8.

[0073] It should be noted that the first wire 21 includes at least one wire harness, and the second wire 22 includes at least one wire harness, and the specific number of the wire harnesses is determined according to design requirements.

[0074] The first wire 21 and the second wire 22 for connecting to the secondary heating assembly 8 pass through the side wall of the inner shell 3 through the first hole 31, which can reduce the length of the wire 2 located in the inner cavity of the inner shell 3. Using the seal 1 to seal the first hole 31 can reduce the air leakage of the hair dryer and improve the effective power of the hair dryer.

[0075] Reference Figure 2 As an optional solution, the seal 1 includes a wire slot. The wire 2 includes a plurality of wire bundles, and the plurality of wire bundles are arranged in a single row in the wire slot.

[0076] Exemplarily, multiple wire harnesses are arranged in a single row. In this embodiment, multiple wire harnesses are arranged in a single row along the first direction, and the first wire 21, the second wire 22, and the third wire 23 are arranged in contact with each other in sequence along the first direction. The first wire 21 and the second wire 22 are in the same wire slot.

[0077] The wire slot fixes multiple wire harnesses and can maintain the stability of the wire harnesses arranged in a single row, so that the multiple wire harnesses are arranged regularly on the outer side of the inner shell 3.

[0078] Multiple wiring harnesses are arranged in a single row, so the electromagnetic interference between the wiring harnesses is relatively small, and the arrangement and assembly of the wiring harnesses can be facilitated.

[0079] Reference Figure 2 As an optional solution, the sealing member 1 includes a soft rubber member, and the soft rubber member is embedded and fixedly connected with the inner shell 3.

[0080] For example, the soft plastic part is a plastic with a relatively low surface hardness, so as to facilitate the bending and deformation of the soft plastic part. Moreover, the soft plastic part can withstand high temperatures and has better thermal stability.

[0081] Reference Figure 2 As an optional solution, it also includes a wire buckle, which is fixed on the outside of the inner shell 3 and locks the wire 2.

[0082] Exemplarily, the wire buckle includes a first wire buckle group, a second wire buckle group and a third wire buckle group; the first wire buckle group includes a first wire buckle 41, a second wire buckle 42, a third wire buckle 43 and a fourth wire buckle 44; the second wire buckle group includes a second wire buckle 42, a third wire buckle 43 and a fifth wire buckle 45; the third wire buckle group includes a wire buckle rib 46.

[0083] The first wire clamping group is used to fix the second wire 22 arranged on the outer side of the inner shell 3; the second wire clamping group is used to fix the first wire 21 arranged on the outer side of the inner shell 3; the third wire clamping group is used to fix the third wire 23 arranged on the outer side of the inner shell 3.

[0084] Using the wire clips to fix the wires 2 in an orderly manner can facilitate the assembly and fixation of the wires 2, and facilitate the quality inspection of the wires 2 at a later time to determine whether there is a wire harness missing or misplaced.

[0085] Using different first wire clamping buckle groups, second wire clamping buckle groups and third wire clamping buckle groups to fix the second wire 22, the first wire 21 and the third wire 23 one by one can facilitate the arrangement and assembly of the wires 2, reduce the interference of quality inspection of different wire harnesses, and reduce the mutual influence between the wire harnesses.

[0086] Reference Figure 1 As an optional solution, a fan assembly is also included, and the fan assembly includes a motor 5 and a motor cover 6. The motor 5 is fixedly connected to the inner shell 3 through the motor cover 6, and the motor 5 is used to drive the gas in the inner cavity of the inner shell 3 to accelerate the flow.

[0087] Reference Figure 3 The motor cover 6 is provided with an air inlet surface 61, which is the end surface facing the air flow direction, and the angle between the air inlet surface 61 and the vertical plane is an acute angle; the air inlet surface 61 is provided with an air supply hole 62, and the gas flows into the inner cavity of the inner shell 3 through the air supply hole 62.

[0088] Exemplarily, the motor 5 includes fan blades, and the rotation of the fan blades drives the air to flow, so that the air flows in the inner cavity of the inner shell 3 as a whole along the first direction.

[0089] The motor 5 is fixedly connected to the inner shell 3 via a motor cover 6, so as to reduce the vibration generated during the operation of the motor 5 and the noise generated by the vibration.

[0090] The motor cover 6 as a whole is a cylindrical groove body with an opening arranged along the first direction, and part of the side wall of the cylindrical groove body is semi-annular, which can be understood as the air supply hole 62 is arranged on the bottom wall of the motor cover 6.

[0091] The air inlet surface 61 can also be understood as the outer side surface of the end of the motor cover 6 facing the airflow direction. Figure 4 In the figure, the vertical plane is schematically represented by a dotted line. Figure 4 The angle between the middle air inlet surface 61 and the vertical plane is denoted as a.

[0092] The axis of the air supply hole 62 is set along the first direction, and the cross-section of the air supply hole 62 is determined according to design requirements. In this embodiment, the cross-section shape of the air supply hole 62 is hexagonal. In another embodiment, the cross-section shape of the air supply hole 62 is square, circular or elliptical.

[0093] A plurality of air supply holes 62 are arranged on the air inlet surface 61 , and the plurality of air supply holes 62 are arranged on the air inlet surface 61 , and the arrangement method is determined according to design requirements.

[0094] Specifically, when the motor 5 is started, the air flows in the inner shell 3 along the first direction, and the air enters the motor cover 6 from the air supply hole 62 and flows along the first direction.

[0095] Due to the influence of the air inlet surface 61, the air is spread outward from the middle of the air inlet surface 61 in sequence, and directly enters around the fan blades of the motor 5 through the air inlet holes, thereby improving the utilization rate of the fan blades and reducing the noise generated by the rotation of the fan blades.

[0096] Furthermore, the hair dryer further comprises a circuit board, which is located at one end of the motor cover 6 facing the direction of gas flow. The circuit board, the air inlet surface 61 and the fan assembly are arranged in sequence along the first direction.

[0097] The air entering the hair dryer will take away the heat generated by the circuit board as it flows, which helps to cool the circuit board and reduce the energy consumption caused by the heating unit heating the air.

[0098] Reference Figure 3 As an optional solution, the air inlet surface 61 is a conical surface.

[0099] Exemplarily, the air inlet surface 61 is a conical surface. In another embodiment, the air inlet surface 61 may be a parabolic surface.

[0100] When air flows on the conical air inlet surface 61, the resistance is relatively small and the air flows stably.

[0101] Reference Figure 4 As an optional solution, the angle between the air inlet surface 61 and the vertical plane is a, where 0°<a<60°.

[0102] Specifically, the angle between the air inlet surface 61 and the vertical plane is greater than 0° and less than 60°. In this embodiment, the angle between the air inlet surface 61 and the vertical plane is 20°. In another embodiment, the angle between the air inlet surface 61 and the vertical plane is 5°, 13°, 21°, 25°, 30°, 46°, 50° or 59°.

[0103] After testing different angles between the air inlet surface 61 and the vertical plane, it was found that when the angle was between 0°<a<60°, the noise of the hair dryer was relatively small. When the angle between the air inlet surface 61 and the vertical plane was 20°, the noise generated by the hair dryer was minimal, which can reduce the sound generated by the hair dryer and improve the user experience.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and description of the present application.
