Description

Technical Field

[0001] The present invention relates to the field of hair drying devices with air flow, and in particular to a hot air comb. Background Art

[0002] The existing hot air comb comprises a motor, a heating frame and a comb head with comb teeth and an air flow outlet. The fan blades of the motor drive the air to flow toward the heating frame, and the air temperature of the air passing through the heating frame is increased and then blown out from the comb head.

[0003] In the existing hot air comb, the motor is arranged at the lower part of the heating frame, and the combing head is arranged at the upper part of the heating frame. When the whole machine is working, the fan blades of the motor rotate, and air is sucked in from the air inlet at the bottom of the hot air comb, passes through the motor and blows through the heating frame, taking away the heat energy generated by the heating frame, and is blown out from the air flow outlet of the combing head through the air duct at the upper end, so that the hot air comb can achieve the effect of blowing and combing hair.

[0004] The existing hot air comb is relatively tall, difficult to operate, and has a poor user experience. Utility Model Content

[0015] In some embodiments, the air supply channel includes an air supply hole disposed on a side wall of the heating rack.

[0016] In some embodiments, it also includes a comb plate arranged around the air guide tube on its outer side, and a plurality of air outlet areas are arranged on the comb plate. The air guide tube can rotate relative to the comb plate so that the air outlet has a plurality of air outlet positions in the circumferential direction and connects different air outlet areas at different air outlet positions. The heating frame is provided with air supply holes at the positions corresponding to the air outlet positions.

[0017] In some embodiments, the air guide cylinder includes an outer shell and a cylinder; wherein the cylinder is located inside the outer shell, and the cylinder is in a first cavity; the heating frame is located in the inner cavity of the cylinder; there is a first gap between the cylinder and the outer shell, and the first guide member guides the air in the second cavity to flow to the first gap, and the air in the first gap flows toward the first air outlet.

[0037] 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 inconvenience in using a hot air comb in the related art, and obtain the technical solution of the embodiments of the present application through reasonable analysis.

[0038] Reference Figure 1 The hot air comb includes a handle and a comb plate 8, the comb plate 8 is provided with comb teeth, an air guide tube is provided in the comb plate 8, one end of the air guide tube is connected to a heating frame, and a motor is provided at the end of the heating frame away from the air guide tube, and the motor is located in the handle.

[0039] An air inlet is provided on the handle, and the fan blades on the motor drive the air from the air inlet into the hot air comb and flow to the heating frame. The heating frame can heat the air. After passing through the heating frame, the air enters the air guide tube, and the air guide tube guides the air flow and blows it out from the comb plate 8, thereby heating the hair when the comb teeth are used to comb the hair.

[0040] In the prior art, the motor, the heating frame and the air guide tube are arranged in sequence along the height direction of the hot air comb, so that the height of the hot air comb is relatively long. When the user holds the handle, the hot air comb is not convenient to use due to the overall long height.

[0041] Although a portion of the heating frame can be extended into the air guide duct to reduce the overall height of the hot air comb, the extension of the heating frame will block a portion of the air outlet of the air guide duct, resulting in no or very little air flowing through a portion of the air outlet of the air guide duct, thereby reducing the actual height of the air outlet of the air guide duct.

[0042] The technical solution is mainly to reduce the height of the hot air comb while ensuring that the height of the existing air outlet of the air guide duct remains unchanged, thereby making it easier for users to use the hot air comb.

[0043] Reference Figure 2 To this end, the present application provides a hot air comb, comprising a heating frame 1, an air guide tube 2, and a first flow guide member 3; wherein the heating frame 1 is at least partially located in the inner cavity of the air guide tube 2; the inner cavity of the air guide tube 2 comprises a first cavity 21 and a second cavity 22 for accommodating part of the heating frame 1. The first cavity 21 and the second cavity 22 are sequentially arranged along a first direction, so that the air entering the second cavity 22 is the air heated by the heating frame 1, and the first direction is the axial direction of the air guide tube 2.

[0044] Reference Figure 3 A plurality of air outlets 23 are arranged on the side wall of the air guide cylinder 2, and the plurality of air outlets 23 include a first air outlet 231 in the same area as the first cavity 21 along the first direction and a second air outlet 232 in the same area as the second cavity 22. The first flow guide member 3 is located in the inner cavity of the air guide cylinder 2, with one end located at the first air outlet 231 and the other end located in the second cavity 22, so as to guide the air in the second cavity 22 to flow toward the first air outlet 231, thereby solving the technical problem of the excessive length of the hot air comb in the prior art.

[0045] 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.

[0046] For the convenience of explanation, a first direction is defined, and the first direction is the axial direction of the air guide tube 2. In the drawings, the first direction is represented as the X direction.

[0047] Reference Figure 2 The embodiment of the present application discloses a hot air comb, including a heating frame 1, an air guide tube 2 and a first guide member 3; wherein the heating frame 1 is at least partially located in the inner cavity of the air guide tube 2; the inner cavity of the air guide tube 2 includes a first cavity 21 and a second cavity 22 for accommodating part of the heating frame 1.

[0048] Reference Figure 3 The first cavity 21 and the second cavity 22 are sequentially arranged along the first direction, so that the air entering the second cavity 22 is the air heated by the heating frame 1, and the first direction is the axial direction of the air guide tube 2; a plurality of air outlets 23 are arranged on the side wall of the air guide tube 2, and the plurality of air outlets 23 include a first air outlet 231 in the same area as the first cavity 21 along the first direction and a second air outlet 232 in the same area as the second cavity 22.

[0049] The first flow guide member 3 is located in the inner cavity of the air guide cylinder 2 , with one end located at the first air outlet 231 and the other end located in the second cavity 22 , so as to guide the air in the second cavity 22 to flow toward the first air outlet 231 .

[0050] Reference Figure 2 For example, the heating rack 1 is a device that generates heat when powered, and the temperature of the air increases after passing through the heating rack 1. The air guide cylinder 2 is a cylindrical structure, with one end of the air guide cylinder 2 facing the motor 7 open and the end away from the motor 7 closed.

[0051] The inner cavity of the air guide tube 2 is divided into two parts, one part is used to accommodate the extension of part of the heating frame 1, and the other part does not have the heating frame 1. In the attached figure, the inner cavity of the air guide tube 2 is distinguished by a dotted line, so that the inner cavity of the heat conduction tube is divided into a first cavity 21 and a second cavity 22. For details, please refer to Figure 2 or Figure 3 .

[0052] It should be noted that the actual boundary between the first cavity 21 and the second cavity 22 is determined according to needs. It is only necessary to understand that the first cavity 21 is the part that can extend into the heating frame 1, and the second cavity 22 is the part that does not extend into the heating frame 1, and both the first cavity 21 and the second cavity 22 need to have corresponding air outlets 23.

[0053] In this embodiment, a portion of the heating frame 1 extends into the first air guiding cavity 21, and another portion is located outside the inner cavity of the air guiding cylinder 2. In another embodiment, the heating frame 1 may be completely located in the first cavity 21.

[0054] An air outlet 23 is provided on the side wall of the air guide tube 2. Figure 2 Four air outlets 23 are shown in the figure, and the length of the air outlet 23 is a square hole along the first direction, and the air outlets 23 are arranged in sequence along the first direction. The figure only shows one air outlet 23 arranged along the circumference of the air guide duct 2, and one air outlet 23 includes four air outlets 23 arranged in sequence along the first direction.

[0055] In another embodiment, multiple air outlets 23 may be provided in the circumference of the air guide tube 2 according to design requirements, and the multiple air outlets 23 are closely provided along the circumference of the air guide tube 2 .

[0056] Reference Figure 3 The air outlet 23 includes a first air outlet 231 and a second air outlet 232. The first air outlet 231 is an air outlet 23 at the same height as the first cavity 21, and the second air outlet 232 is an air outlet 23 at the same height as the second cavity 22. In this embodiment, the height represents the position or size along the first direction. The first air outlet 231 flows out the air in the first cavity 21, and the second air outlet 232 flows out the air in the second cavity 22.

[0057] One end of the first guide member 3 is located at the first air outlet 231 , and the other end is located in the second cavity 22 , so as to guide the air in the second cavity 22 to flow toward the first air outlet 231 .

[0058] The air in the second cavity 22 is guided by the first flow guide 3 during its flow, and its flow direction is changed, so that the air flows into the first cavity 21 and flows out from the first air outlet 231. It should be noted that the first cavity 21 is not completely filled with the heating rack 1, and there is a certain gap in the first cavity 21, which is located outside the heating rack 1. The air enters the first cavity 21 from the second cavity 22, and the area entered is the above-mentioned gap, and will not return to the heating rack 1.

[0059] This embodiment realizes that after the heating frame 1 is extended into the air guide tube 2, although the first air outlet 231 is blocked by the heating frame 1, part of the air in the second cavity 22 can enter the first cavity 21 and flow out from the first air outlet 231. When the height of the air outlet 23 remains unchanged, the overall height of the hot air comb is reduced, thereby facilitating user use.

[0060] It should be noted that when a part of a hole on the side wall of the air guide tube 2 is connected to the first cavity 21 and the other part is connected to the second cavity 22 , the part of the hole can be understood as the first air outlet 231 and the other part as the second air outlet 232 .

[0061] It should be noted that only one first flow guide member 3 is illustrated in the accompanying drawings. In another embodiment, the number of first flow guide members 3 can be determined according to design requirements. For example, two first flow guide members 3 are provided, and the two first flow guide members 3 are arranged sequentially along the first direction.

[0062] Reference Figure 2 As an optional solution, the heating frame 1 includes a tubular mica shell 11, a partition 12 and a heating wire 13; wherein the partition 12 is fixed to the inner cavity of the mica shell 11; and the heating wire 13 is fixed to the partition 12.

[0063] Exemplarily, the mica shell 11 is a pipe structure with two ends opened along the first direction. The partition 12 is made of mica sheets, and is a rectangular plate with a length along the first direction. One end of the partition 12 in the width direction is in contact with the side wall of the mica shell 11, and the other end is located in the middle of the mica shell 11. A plurality of partitions 12 are provided, and the plurality of partitions 12 are evenly distributed along the circumference of the mica shell 11. In this embodiment, six partitions 12 are provided. The heating wire 13 is fixed on the partition 12, and the heating wire 13 is arranged on the partition 12 according to design requirements.

[0064] The heating frame 1 utilizes the effect of resistance heating. The current passes through the ceramic mica sheet to make it heat up. The heating frame 1 is composed of hundreds of ceramics mixed with different types of metal wires, and is formed into a heating device with a certain shape through plastic injection molding. When the power is turned on, the resistance of the heating frame 1 allows the current to pass through, and the current heats the heating frame 1 and makes it heat up.

[0065] The heating frame 1 can heat the air flowing through it, so that the temperature of the air driven by the motor 7 increases after passing through the heating frame 1, and the temperature of the air entering the first cavity 21 meets the design requirements.

[0066] Reference Figure 3 As an optional solution, the air guide cylinder 2 includes a shell 24 and a cylinder 25; wherein the cylinder 25 is located in the shell 24, and the cylinder 25 is in the first cavity 21; the heating frame 1 is located in the inner cavity of the cylinder 25; there is a first gap between the cylinder 25 and the shell 24, and the first guide member 3 guides the air in the second cavity 22 to flow to the first gap, and the air in the first gap flows toward the first air outlet 231.

[0067] Specifically, the air outlet 23 is arranged on the side wall of the housing 24, and the first flow guide member 3 is connected to the side wall of the housing 24. The cylinder 25 is located in the housing 24, the cylinder 25 is located in the first cavity 21, and the heating frame 1 is installed in the inner cavity of the cylinder 25.

[0068] Furthermore, a limiting ring is provided on the inner wall of one end of the cylinder 25 facing the second cavity 22 , and the limiting ring contacts the end surface of the heating frame 1 facing the second cavity 22 , so that the cylinder 25 can limit the heating frame 1 along the first direction.

[0069] In this embodiment, the cylinder 25 is a pipe structure with two ends opened along the first direction. In another embodiment, the cylinder 25 can be a mesh cage structure or a frame structure, or a plurality of holes can be provided on the side wall of the cylinder 25.

[0070] It should be noted that the first gap refers only to the area near the first air outlet 231 in the gap between the cylinder 25 and the housing 24 .

[0071] Furthermore, the air guide tube 2 also includes a middle piece, which is located in the first cavity 21 and connects the outer shell 24 and the cylinder 25 . The middle piece can close the first gap in the air guide tube 2 toward one end of the motor 7 .

[0072] The intermediate piece can avoid air flow loss caused by air flowing out from the first gap toward one end of the motor 7 .

[0073] Reference Figure 3As an optional solution, the first flow guide member 3 includes a plate-shaped first portion 31 and a second portion 32, wherein one end of the first portion 31 is located at the first air outlet 231, and the other end is connected to the second portion 32; the second portion 32 is a portion of the first flow guide member 3 that is directly opposite to the heating rack 1 along the first direction. Along the first direction, the distance from the end of the second portion 32 away from the first portion 31 to the heating rack 1 is less than the farthest distance from the second portion 32 to the heating rack 1.

[0074] Exemplarily, the first flow guiding member 3 is a plate member, the first flow guiding member 3 and the air guide cylinder 2 are formed in one piece, and part of the side wall of the first flow guiding member 3 is an arc-shaped side wall in contact with the side wall of the outer shell 24 .

[0075] In the drawings, along the first direction, the distance from the end of the second portion 32 away from the first portion 31 to the heating frame 1 is represented as d1, and the farthest distance from the second portion 32 to the heating frame 1 is represented as d2, and d1 is smaller than d2.

[0076] The air flowing from the heating frame 1 along the first direction is guided by the first part 31, and the flow direction is changed. The flow direction of the air is away from the first direction and inclined relative to the first direction and toward the first air outlet 231. Part of the air flows along the second part 32 toward the first gap and flows out from the first air outlet 231.

[0077] Reference Figure 3 As an optional solution, the second portion 32 is an arc-shaped portion with an opening toward the heating frame 1 .

[0078] Exemplarily, the second portion 32 is an arc-shaped plate member. The arc-shaped second portion 32 can reduce energy loss of the air flowing in the first direction when changing the flow direction toward the first cavity 21 , and reduce the turbulence formed near the first guide member 3 .

[0079] It should be noted that the arc shape of the second portion 32 represents a cross section formed by cutting the second portion 32 using the first plane. Figure 3 In the cross section shown in FIG. 2 , the first plane is a plane formed by the center line of the air outlet 23 and the center line of the cylinder 25 .

[0080] Furthermore, the smooth transition between the second portion 32 and the first portion 31 further reduces the resistance of the air when it flows on the surface of the first guide member 3 .

[0081] In another embodiment, the second portion 32 is an L-shaped plate with one end connected to the first portion 31 , and the opening of the second portion 32 faces the heating frame 1 and the first air outlet 231 .

[0082] Reference Figure 3As an optional solution, the hot air comb further includes a second flow guide member 4 and a third flow guide member 5; wherein the first flow guide member 3, the second flow guide member 4 and the third flow guide member 5 are sequentially arranged along the first direction.

[0083] One end of the second flow guiding member 4 and the third flow guiding member 5 are both located at the second air outlet 232 , and the other end thereof are both located in the second cavity 22 .

[0084] Exemplarily, the first flow guiding member 3 , the second flow guiding member 4 and the third flow guiding member 5 are sequentially arranged along the first direction, so that there is one first air outlet 231 and there are three second air outlets 232 .

[0085] The size of the first air outlet 231 along the first direction is determined according to design requirements. In this embodiment, the length of the first air outlet 231 along the first direction is greater than the length of the second air outlet 232 along the first direction.

[0086] The first guide member 3 , the second guide member 4 and the third guide member 5 evenly divide the wind blown out from the heating frame 1 along the first direction into multiple sections, so that the air can be evenly blown out from the side air outlet 23 .

[0087] In this embodiment, the specifications of the first flow guide 3, the second flow guide 4 and the third flow guide 5 are adjusted, including the curvature and the length, so as to adjust the air volume of each air outlet 23 so that the air flows out relatively evenly from the air outlet 23. In another embodiment, the size of the air outlet 23 along the first direction and the gaps between the first flow guide 3, the second flow guide 4 and the third flow guide 5 along the first direction can be adjusted to adjust the air volume of each air outlet 23 so that the air flows out relatively evenly from the air outlet 23.

[0088] In another embodiment, the number of guide members is determined as needed, and the hot air comb further includes a fourth guide member, and the first guide member 3, the second guide member 4, the third guide member 5 and the fourth guide member are sequentially arranged along the first direction.

[0089] Reference Figure 3 As an optional solution, the portion of the second guide member 4 facing the heating frame 1 along the first direction is smaller than the portion of the third guide member 5 facing the heating frame 1 along the first direction, and is larger than the portion of the first guide member 3 facing the heating frame 1 along the first direction.

[0090] Exemplarily, part of the air flowing out from the heating rack 1 along the first direction into the second cavity 22 is guided by the first guide piece 3 into the first cavity 21, part of the air is guided by the second guide piece 4 into between the second guide piece 4 and the first guide piece 3, part of the air is guided by the third guide piece 5 into between the third guide piece 5 and the second guide piece 4, and part of the air flows to the top of the outer shell 24 and into between the top of the outer shell 24 and the third guide piece 5.

[0091] The first flow guide member 3 , the second flow guide member 4 and the third flow guide member 5 can respectively guide a portion of the air flow, so that the air can flow out from the air outlet 23 more evenly.

[0092] Reference Figure 3 As an optional solution, the effective lengths of the first flow guiding member 3, the second flow guiding member 4 and the third flow guiding member 5 along the first direction gradually decrease.

[0093] Exemplarily, the effective length of the first flow guiding member 3 along the first direction is denoted as a, the effective length of the second flow guiding member 4 along the first direction is denoted as b, and the effective length of the third flow guiding member 5 along the first direction is denoted as c, wherein a>b>c.

[0094] By adjusting the curvature of the first flow guide member 3, the second flow guide member 4 and the third flow guide member 5, the air volume of each air outlet 23 is adjusted so that the air flows out from the air outlet 23 relatively evenly, and the air flow rate flowing out from each height of the air guide duct 2 is basically the same.

[0095] Reference Figure 4 As an optional solution, it also includes an air supply channel 6, which connects the first cavity 21 with the inner cavity of the heating frame 1.

[0096] Exemplarily, the air supply channel 6 connects the first cavity 21 with the inner cavity of the heating frame 1. Specifically, the air supply channel 6 connects the first gap with the inner cavity of the mica shell 11. The heated air in the mica shell 11 is directly transported to the first gap through the air supply channel 6 and flows out from the first air outlet 231.

[0097] The heated air in the heating frame 1 is divided into two parts, one of which flows to the first cavity 21 through the air supply channel 6 and enters the first gap; the other part flows from the mica shell 11 along the first direction away from the port of the motor 7 to the second cavity 22. A part of the hot air in the second cavity 22 flows to the first air outlet 231 through the guidance of the first guide member 3.

[0098] The provision of the air supply channel 6 helps to reduce the flow rate of the air guided by the first guide member 3, thereby helping the heating rack 1 to extend further into the air guide tube 2, further reducing the height of the hot air comb.

[0099] The air supply channel 6 reduces the flow rate of the air guided by the first guide member 3, which helps to reduce the width of the air flow channel that needs to be reserved between the first guide member 3 and the heating frame 1, and further helps to reduce the overall lateral size of the hot air comb.

[0100] Reference Figure 4 As an optional solution, the air supply channel 6 includes an air supply hole 61 arranged on the side wall of the heating frame 1.

[0101] Exemplarily, the shape of the air supply hole 61 is determined according to design requirements. Exemplarily, the air supply hole 61 is a circular hole arranged on the side wall of the mica shell 11; optionally, the air supply hole 61 is a waist-shaped hole, a square hole or an elliptical hole.

[0102] A plurality of air supply holes 61 are provided on the side wall of the mica shell 11 , and the plurality of air supply holes 61 are distributed at intervals along the first direction and the circumference of the mica shell 11 on the side wall of the mica shell 11 .

[0103] It should be noted that, in this embodiment, the air guide duct 2 includes a cylinder 25, and the air supply channel 6 also includes a through hole set on the cylinder 25. The through hole is not shown in the accompanying drawings. The air in the heating rack 1 passes through the air supply hole 61 and then through the through hole on the cylinder 25 into the first gap and flows out from the first air outlet 231.

[0104] In another embodiment, the air guide tube 2 does not have the cylinder 25 structure, or the cylinder 25 of the air guide tube 2 is set as a frame structure, and the air in the heating frame 1 can directly enter the first gap through the air supply hole 61 and flow out from the first air outlet 231.

[0105] In another embodiment, the air supply channel 6 includes a ventilation pipe, one end of which is located in the inner cavity of the heating frame 1, and the other end is located in the first gap. Exemplarily, the axis of the ventilation pipe is arranged along a vertical first direction, and the ventilation pipe passes through the mica shell 11 and the cylinder 25.

[0106] refer to Figure 1 and Figure 4 As an optional solution, a plurality of air outlet areas with air flow outlets can be arranged on the comb plate 8 surrounding the outside of the air guide cylinder 2, and different air outlet areas have different air outlet areas, as well as different wind speeds and wind pressures, so that the user can obtain a variety of hair blowing styling modes by switching between different air outlet areas of the hot air comb. The air guide cylinder 2 is rotatable relative to the comb plate 8, and the user rotates the air guide cylinder 2 to align the air outlet 23 in different directions, so that the air flow is blown out from different air outlet areas, thereby realizing the switching of the air outlet position and air outlet mode of the hot air comb.

[0107] For example, reference Figure 1The comb plate 8 is also provided with an air guide 9 that cooperates with the air guide cylinder 2. When the air outlet 23 is facing the air guide 9, the air guide 9 can guide the airflow to the air outlet areas on both sides of the air guide 9. At this time, the hot air comb can form a double-sided air outlet effect. When the air outlet 23 is aimed at the air outlet area on one side, the air guide 9 abuts against the side wall of the air guide cylinder 2 to prevent the airflow from flowing to the air outlet area on the other side. At the same time, the opposite side of the air guide 9 can also be provided with a corresponding air guide structure to cooperate with the air guide cylinder 2 to ensure that the hot air comb only forms a single-sided air outlet effect at this time. In addition, the opposite side of the air guide 9 can also be provided with a strip airflow outlet for concentrated airflow, so that users can achieve fast hair drying through high-speed hot airflow. It can be understood that the layout of the air outlet area on the comb plate 8 can be diverse, and the air guide structure in the comb plate 8 is not limited to the form of the air guide member 9. The air guide structure can be an independent component or a part of the comb plate. The specific structure of the air guide structure can be designed according to the actual working conditions in the hot air comb.

[0108] The heating frame 1 is fixed relative to the comb plate 8, and is provided with air supply holes 61 at positions corresponding to each air outlet position of the air outlet 23, so that when the air outlet 23 is aimed at any air outlet area, part of the air flow in the heating frame 1 can flow to the first air outlet 231 through the air supply holes 61 and be blown out from the comb plate 8.
