Description

Technical Field

[0001] The present application relates to the technical field of hair dryers, and in particular to a support member, a heating mechanism and a hair dryer. Background Art

[0002] After washing hair, when people need to wash, sleep or go out, it takes a lot of time to dry hair naturally or with a low-speed hair dryer. High-speed hair dryers facilitate people's lives, shorten the time people spend drying their hair, and facilitate people's lives. At present, in order to be able to blow out wind of different temperatures, high-speed hair dryers are usually composed of a group of electric heating wires and a small fan. If only the small fan rotates and the electric heating wire does not work, the high-speed hair dryer can only blow out cold air. When the electric heating wire and the small fan work at the same time, the electric heating wire assembly generates heat, and the wind blown out by the fan passes through the electric heating wire to become hot air.

[0003] At present, after the air flow entering from the end of the handle of the hair dryer flows through the air outlet of the handle, the air flow will flow out of the air outlet of the hair dryer along the periphery of the heating mechanism of the hair dryer. This air flow direction design will cause the wind speed at different positions of the hair dryer outlet to be quite different. The wind speed of the hair dryer outlet close to the handle is too high, while the wind speed of the hair dryer outlet far from the handle is too low, which seriously affects the user experience. In addition, the wind speed of the hair dryer outlet far from the handle is too low, which is not conducive to the air flow to take away the heat from the part of the heating mechanism far from the handle. In other words, it is easy to cause the local temperature of the heating mechanism to be too high, which increases the risk of overheating of the heating mechanism and makes the hair dryer easily damaged. Utility Model Content

[0004] In order to solve the above problems, the present application provides a support member, a heating mechanism and a hair dryer, which are cleverly designed and simple in structure. By setting a plate-shaped first air guide portion, while ensuring that the airflow can pass through the first notch and blow out evenly from the second notch, the amount of air blown out from the second notch is also controlled, so that the airflow velocity at the air outlet of the hair dryer is relatively uniform. The technical solution adopted by the present application is as follows:

[0005] A support member, comprising:

[0006] A barrel-shaped support member body is provided with a first notch and a second notch, the first notch and the second notch are arranged opposite to each other; a plate-shaped first guide portion is provided on the inner wall of the support member body and adjacent to the edges on both sides of the second notch, the first guide portion extends in the axial direction close to the support member body.

[0007] By setting a plate-shaped first air guide portion, the first air guide portion is like two doors that are not fully opened, and the air flow can flow through the space between the two first air guide portions. While ensuring that the air flow can pass through the first gap and be blown out evenly from the second gap, the amount of air blown out from the second gap is also controlled, so that the air flow velocity at the air outlet of the hair dryer is more uniform.

[0008] In some embodiments, the distance between two adjacent ends of the first guide portions is smaller than the width of the first notch.

[0009] By setting the distance between the two adjacent ends of the two first guide parts to be smaller than the width of the first notch, the first guide part can increase the blocking effect on the airflow entering from the first notch, thereby reducing the amount of airflow flowing out of the second notch, and avoiding excessive airflow flowing out of the second notch, resulting in a smaller airflow in other parts of the periphery of the support body except for the second notch, so that the airflow distribution around the support body is more uniform, that is, the airflow at the air outlet of the hair dryer is more uniform.

[0010] In some embodiments, the support member body is further provided with a third notch, and the third notch is located on a side of the first guide portion away from the second notch.

[0011] Since the periphery of the support body corresponding to the third notch is located between the first notch and the second notch, the airflow at this position is relatively small. By setting the third notch, the airflow blocked by the first guide portion can flow out from the third notch to compensate for the airflow at the periphery of the support body corresponding to the third notch, thereby making the airflow distribution at the periphery of the support body more uniform.

[0012] In some embodiments, the support member body is further provided with a fourth notch, the fourth notch is located on a side of the third notch away from the first guide portion, and the height of the fourth notch is smaller than the height of the third notch.

[0013] By providing the fourth notch and making the height of the fourth notch smaller than the height of the third notch, the airflow blocked by the first air guide portion can flow out more from the third notch and less from the fourth notch, so as to balance the airflow at the periphery of the support body corresponding to the third notch and the fourth notch respectively, thereby making the airflow distribution at the periphery of the support body more uniform.

[0014] In some embodiments, a support portion is disposed in each of the first notch and the second notch, the support portion is connected to the support member body, and the support portion separates the first notch and the second notch into two equal parts.

[0015] By providing the support part, the airflow passing through the first notch and the second notch can be divided respectively, which has a rectifying effect on the airflow, and reduces the turbulence of the airflow passing through the first notch and the airflow passing through the second notch, thereby reducing wind noise. The existence of the support part can also accelerate the airflow passing through the first notch and the airflow passing through the second notch, so that the airflow distribution around the support body is more uniform. In addition, a fixing plate can be installed on the support part to strengthen the support for the heating wire.

[0016] In some embodiments, a first reinforcing rib is provided on a side of the support portion close to the inner side of the support body, and the first reinforcing rib is connected to the inner wall of the support body.

[0017] By providing the first reinforcing rib, the support portion can be strengthened to reduce the risk of bending and vibration of the support portion, thereby reducing the noise when the airflow passes through the first notch and the second notch and extending the service life of the support member.

[0018] In some embodiments, the first guide portion and the first reinforcing rib are both connected to the bottom of the support body.

[0019] By connecting the first guide part and the first reinforcement rib to the bottom of the support body, the connection stability of the first guide part and the first reinforcement rib with the support body can be improved, thereby reducing the risk of damage to the first guide part and the support part.

[0020] In some embodiments, a bending portion is provided at the bottom of the support body, and the bending portion can cooperate with the first guide portion to clamp the object to be fixed.

[0021] By providing the bending portion, it is convenient to fix the object to be fixed into the support body, thereby improving the installation and removal efficiency of the object to be fixed.

[0022] On the other hand, the present application provides a heating mechanism, including a fixing plate, a heat insulation cover and the aforementioned support member, wherein the fixing plate is arranged at intervals around the outer periphery of the support member, the fixing plate is used to support the heating wire, and the heat insulation cover is sleeved on the outer periphery of the whole formed by connecting the fixing plate and the support member.

[0023] On the other hand, the present application also provides a hair dryer, comprising the aforementioned support member or the aforementioned heating mechanism.

[0040] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0041] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0042] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0043] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0045] The present application provides a support member, referring to Figure 1 , Figure 2 , including a barrel-shaped support body 1, the support body 1 is provided with a first notch 2 and a second notch 3, and the first notch 2 and the second notch 3 are arranged opposite to each other. It can be understood that when in use, the first notch 2 is adjacent to the air outlet of the hair dryer handle, that is, the air outlet of the hair dryer handle faces the first notch 2, and the first notch 2 is opened to introduce part of the airflow flowing out of the hair dryer handle into the support body 1, while the second notch 3 is opened to guide at least part of the airflow entering the support body 1 to the periphery of the support body 1. It is worth noting that not all of the airflow flowing out of the hair dryer handle enters the support body 1, but part of the airflow does not pass through the first notch 2 and is directly distributed around the periphery of the support body 1, which can be combined with Figure 2 A plate-shaped first air guide 4 is provided on the inner wall of the support body 1 and adjacent to the edges on both sides of the second notch 3. The first air guide 4 extends toward the axial direction of the support body 1.

[0046] Understandably, reference Figure 2 , the first air guide 4 is like two doors that are not fully opened. At least part of the airflow entering the first gap 2 can flow through the space between the two first air guides 4. While ensuring that the airflow can pass through the first gap 2 and blow out evenly from the second gap 3, the amount of air blown out from the second gap 3 is also controlled, so that the airflow velocity at the air outlet of the hair dryer is more uniform. Obviously, by controlling the opening degree of the two doors (first air guides 4) or the distance a between the edges of the two doors, the purpose of adjusting the amount of air flowing between the two first air guides 4 can be achieved, thereby realizing the adjustment of the amount of air flowing out of the second gap 3. Reference Figure 2 Preferably, the distance a between the two adjacent ends of the two first guide portions 4 is smaller than the width b of the first notch 2. By setting the distance a between the two adjacent ends of the two first guide portions 4 to be smaller than the width b of the first notch 2, the first guide portions 4 can increase their ability to block the airflow entering from the first notch 2, thereby reducing the amount of air flowing out of the second notch 3, thereby avoiding excessive airflow flowing out of the second notch 3, resulting in a smaller airflow in other parts of the periphery of the support body 1 except for the second notch 3, thereby making the airflow distribution around the support body 1 more uniform, that is, making the airflow at the air outlet of the hair dryer more uniform.

[0047] refer to Figure 1-Figure 3 In one embodiment, the support body 1 is further provided with a third notch 5, and the third notch 5 is located on a side of the first guide portion 4 away from the second notch 3. It is worth noting that the height of the second notch 3 can be greater than the height of the third notch 5, or less than the height of the third notch 5. Preferably, the height of the second notch 3 is the same as the height of the third notch 5.

[0048] It is easy to understand that since the periphery of the support body 1 corresponding to the third notch 5 is located between the first notch 2 and the second notch 3, the air flow at this position is relatively small. By setting the third notch 5, the airflow blocked by the first guide part 4 can flow out from the third notch 5 to supplement the airflow at the periphery of the support body 1 corresponding to the third notch 5, so that the airflow distribution at the periphery of the support body 1 is more uniform.

[0049] refer to Figure 1-Figure 3 In one embodiment, the support body 1 is further provided with a fourth notch 6, which is located on the side of the third notch 5 away from the first air guide 4, and the height of the fourth notch 6 is less than the height of the third notch 5. By providing the fourth notch 6 and making the height of the fourth notch 6 less than the height of the third notch 5, the airflow blocked by the first air guide 4 can flow out more from the third notch 5, and less from the fourth notch 6, so as to balance the airflow at the periphery of the support body 1 corresponding to the third notch 5 and the fourth notch 6, so that the airflow distribution at the periphery of the support body 1 is more uniform.

[0050] It is worth noting that reference Figure 1-Figure 3In one embodiment, a support portion 7 is provided in each of the first notch 2 and the second notch 3. The support portion 7 is connected to the support body 1, and the support portion 7 separates the first notch 2 and the second notch 3 into two equal parts. The support portion 7 can divide the airflow passing through the first notch 2 and the second notch 3 respectively, rectifying the airflow, and reducing the turbulence of the airflow passing through the first notch 2 and the airflow passing through the second notch 3, thereby reducing wind noise. At the same time, the presence of the support portion 7 can also accelerate the airflow passing through the first notch 2 and the airflow passing through the second notch 3, so that the airflow distribution around the support body 1 is more uniform. In addition, a fixing plate 11 can be installed on the support portion 7 to strengthen the support for the heating wire.

[0051] Preferably, reference Figure 1-Figure 3 , a first reinforcing rib 8 is provided on one side of the support portion 7 close to the inner side of the support body 1, and the first reinforcing rib 8 is connected to the inner wall of the support body 1. It is easy to understand that the first reinforcing rib 8 can reinforce the support portion 7, reduce the risk of bending and vibration of the support portion 7, thereby reducing the noise when the airflow passes through the first notch 2 and the second notch 3, and can also extend the service life of the support. It is worth noting that, based on the above embodiments, in one embodiment, the first guide portion 4 and the first reinforcing rib 8 are both connected to the bottom of the support body 1, which can respectively improve the connection stability of the first guide portion 4 and the first reinforcing rib 8 with the support body 1, and reduce the risk of damage to the first guide portion 4 and the support portion 7.

[0052] refer to Figure 3 , Figure 4 In one embodiment, a bending portion 9 is provided at the bottom of the support body 1, and the bending portion 9 can cooperate with the first guide portion 4 to clamp the object to be fixed 10. It is easy to understand that in order to reasonably arrange the components in the hair dryer, or in order to save space in the hair dryer and make the arrangement of the components in the hair dryer more compact, some components (the object to be fixed 10) can be placed in the support body 1, and the object to be fixed 10 can be a negative ion generator, a water ion generator or one or more combinations of other components. In this embodiment, by providing the bending portion 9, it is convenient to fix the object to be fixed 10 into the support body 1, and the installation and removal efficiency of the object to be fixed 10 can be improved.

[0053] refer to Figure 4 The present application provides a heating mechanism, including a fixing plate 11, a heat insulating cover 12 and the aforementioned support member, wherein the fixing plates 11 are arranged at intervals around the outer periphery of the support member, the fixing plates 11 are used to support the heating wire, and the heat insulating cover 12 is sleeved on the outer periphery of the whole formed by connecting the fixing plates 11 and the support member.

[0054] In this embodiment, the specific structure of the support member refers to the aforementioned embodiment. Since the heating mechanism adopts the technical solution of the aforementioned embodiment, it at least has the beneficial effects brought by the technical solution of the aforementioned embodiment, which will not be described one by one here.

[0055] The present application also provides a hair dryer, comprising the aforementioned support member or the aforementioned heating mechanism. In this embodiment, the specific structure of the support member or the heating mechanism refers to the aforementioned embodiment. Since the hair dryer adopts the technical solution of the aforementioned embodiment, it at least has the beneficial effects brought by the technical solution of the aforementioned embodiment, which will not be described one by one here.

[0056] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
