Description

Technical Field

[0001] The present application relates to the technical field of hair dryers, and in particular to a support base, 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 hair dryer's handle 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's air outlet to be quite different. The wind speed of the hair dryer's air outlet close to the handle is too high, while the wind speed of the hair dryer's air outlet far from the handle is too low, which seriously affects the user experience. In addition, the wind speed of the hair dryer's air outlet far from the handle is too low, which is not conducive to the air flow taking 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 seat, a heating mechanism and a hair dryer, which are cleverly designed and simple in structure. By setting a first notch and a second notch, the uniformity of wind speed at different positions of the hair dryer outlet is improved, and the uniformity of air flow temperature at different positions of the hair dryer outlet is also improved, thereby improving the user experience. The technical solutions adopted in the present application are as follows:

[0005] A support seat, which serves as a component of a heating mechanism in a hair dryer, comprises a support seat body, the support seat body is provided with a accommodating chamber, the accommodating chamber is used to accommodate a negative ion generator; a first notch and a second notch are respectively provided on opposite sides of a side wall of the support seat body, the first notch and the second notch are both located at an end of the support seat body away from an air outlet of the hair dryer, the first notch is close to a handle air outlet, the second notch is away from the handle air outlet, and the air outlet direction of the handle air outlet is directly opposite to part of the first notch and part of the side wall of the support seat body.

[0006] By setting the first notch and the second notch, part of the airflow flowing through the handle air outlet directly passes through the first notch and the second notch, and reaches the side of the support base body away from the handle air outlet. Compared with the airflow flowing through the handle air outlet bypassing the outer periphery of the support base body and then reaching the side of the support base body away from the handle air outlet, the flow rate of the airflow on the side of the support base body away from the handle air outlet can be increased, so that the wind speed at different positions of the hair dryer air outlet becomes more uniform, and the air flow temperature at different positions of the hair dryer air outlet becomes more uniform, which improves the user experience and reduces the risk of damage to the heating mechanism and the hair dryer due to excessive local temperature.

[0007] In some embodiments, the first notch and the second notch are consistent in shape and size.

[0008] The first notch and the second notch have the same shape and size, that is, the first notch and the second notch have the same specifications, so there is no need to distinguish between the first notch and the second notch when installing the fixing plate on the support seat body, thereby improving the efficiency of assembling the fixing plate to the support seat body.

[0009] In some embodiments, a guide portion is further included, wherein the guide portion is disposed on an inner wall of the containing chamber, and the guide portion is located on both sides of a first flow channel formed by the first notch and the second notch.

[0010] By providing the guide portion, the vortex effect generated when the airflow flows through the first flow channel can be weakened, thereby reducing the airflow noise generated when the airflow flows through the first flow channel.

[0011] In some embodiments, the guide portion is columnar, and the guide portions are disposed on both sides of the first notch and both sides of the second notch, and the guide portions are chamfered.

[0012] The guide part is designed to be columnar, with a simple structure and ingenious design, which can reduce the difficulty of mold opening when the guide part and the support seat body are formed by an integrated molding process.

[0013] In some embodiments, the guide portion is a hollow structure.

[0014] By designing the guide part as a hollow structure, the wall thickness of the guide part can be reduced, thereby reducing the risk of excessive shrinkage of the guide part during injection molding, and saving raw materials.

[0015] In some embodiments, at least one third notch is further provided on the side walls of the support seat body located on both sides of the first flow channel, and the third notch is used to divert the airflow entering from the first notch.

[0016] By setting the third notch, part of the airflow flowing through the handle air outlet directly passes through the first notch and the third notch to reach the outer periphery of the support base body, thereby further improving the uniformity of wind speed at different positions of the hair dryer air outlet, and further improving the uniformity of air flow temperature at different positions of the hair dryer air outlet.

[0017] In some embodiments, a support column is respectively provided at the first notch and the second notch, the support column at the first notch divides the first notch into two parts evenly, and the support column at the second notch divides the second notch into two parts evenly, and the support column is used to fix the fixing plate of the heating mechanism.

[0018] By setting up the support column, sufficient support can be provided for the fixing plate, avoiding a reduction in the number of fixing plates due to the setting of the first notch and the second notch, thereby affecting the supporting effect of the fixing plate on the heating wire. In addition, the support column evenly separates the airflow passing through the first notch and the second notch, reducing the risk of increased airflow noise due to uneven separation.

[0019] In some embodiments, a first reinforcing rib is provided on a side of the support column close to the containing bin, at least a portion of the length of the first reinforcing rib is fixed to an inner wall of the containing bin, and a thickness of the first reinforcing rib is smaller than a thickness of the support column.

[0020] By setting the first reinforcing rib, the strength of the support column is improved and the risk of the support column breaking or excessive deformation is reduced. At the same time, the first reinforcing rib is equivalent to lengthening the width of the support column along the airflow direction in the first flow channel, reducing the risk of mutual interference between the airflows on both sides of the support column; the thickness of the first reinforcing rib is smaller than the thickness of the support column, which can reduce the airflow noise when the airflow passes through the support column.

[0021] On the other hand, the present application provides a heating mechanism for heating the airflow in a hair dryer, comprising a plurality of fixing plates, a protective cover and the aforementioned support seat, wherein the plurality of fixing plates are arranged at intervals on the periphery of the support seat, and the fixing plates are used to support the heating wire; the protective cover is sleeved on the periphery of the fixing plates, and the protective cover is provided with an air inlet, which is connected to the air outlet of the handle.

[0022] On the other hand, the present application also provides a hair dryer, comprising the aforementioned support base or the aforementioned heating mechanism.

[0023] The support base, heating mechanism and hair dryer provided in the present application have at least one of the following beneficial effects:

[0024] 1. A support base provided by the present application, by providing a first notch and a second notch, allows part of the airflow flowing through the handle air outlet to directly pass through the first notch and the second notch, thereby reaching the side of the support base body away from the handle air outlet. Compared with the airflow flowing through the handle air outlet bypassing the outer periphery of the support base body before reaching the side of the support base body away from the handle air outlet, the flow rate of the airflow on the side of the support base body away from the handle air outlet can be increased, thereby making the wind speed at different positions of the hair dryer air outlet more uniform, and also making the airflow temperature at different positions of the hair dryer air outlet more uniform, thereby improving the user experience and reducing the risk of damage to the heating mechanism and the hair dryer due to excessive local temperature;

[0025] 2. In a support seat provided by the present application, the first notch and the second notch have the same shape and size, that is, the first notch and the second notch have the same specifications, so that when the fixing plate is installed on the support seat body, there is no need to distinguish between the first notch and the second notch, thereby improving the efficiency of assembling the fixing plate to the support seat body;

[0026] 3. A support seat provided in the present application can reduce the vortex effect generated when the airflow flows through the first flow channel by providing a guide portion, thereby reducing the airflow noise generated when the airflow flows through the first flow channel;

The support base provided by the present application is provided with a third notch, so that part of the airflow flowing through the handle air outlet directly passes through the first notch and the third notch, thereby reaching the periphery of the support base body, further improving the uniformity of wind speed at different positions of the hair dryer air outlet, and further improving the uniformity of airflow temperature at different positions of the hair dryer air outlet;

[0030] 7. The support seat provided in the present application can provide sufficient support for the fixing plate by setting the support column, so as to avoid reducing the number of fixing plates due to the setting of the first notch and the second notch, thereby affecting the supporting effect of the fixing plate on the heating wire. In addition, the support column evenly separates the airflow flowing through the first notch and the second notch, thereby reducing the risk of increased airflow noise caused by uneven separation;

[0031] 8. A support seat provided in the present application improves the strength of the support column and reduces the risk of the support column breaking or excessive deformation by setting a first reinforcing rib.

The thickness of the first reinforcing rib is smaller than the thickness of the support column, which can reduce the airflow noise when the airflow passes through the support column.

At present, the hair dryer has problems such as uneven wind speed at different positions of the hair dryer outlet 5 and uneven airflow temperature.

[0048] To improve the above problems, refer to Figure 1-Figure 7 The present application provides a support seat, which serves as a component of a heating mechanism in a hair dryer, including a support seat body 1, the support seat body 1 is provided with a accommodating chamber 2, and the accommodating chamber 2 is used to accommodate a negative ion generator; a first notch 3 and a second notch 4 are respectively provided on opposite sides of a side wall of the support seat body 1, the first notch 3 and the second notch 4 are both located at one end of the support seat body 1 away from an air outlet 5 of the hair dryer, the first notch 3 is close to a handle air outlet 6, and the second notch 4 is away from the handle air outlet 6, and the air outlet direction of the handle air outlet 6 is directly opposite to part of the first notch 3 and part of the side wall of the support seat body 1.

[0049] In this embodiment, by setting the first notch 3 and the second notch 4, part of the airflow flowing through the handle air outlet 6 directly passes through the first notch 3 and the second notch 4, and reaches the side of the support base body 1 away from the handle air outlet 6. Compared with the airflow flowing through the handle air outlet 6 bypassing the outer periphery of the support base body 1 and then reaching the side of the support base body 1 away from the handle air outlet 6, the flow rate of the airflow on the side of the support base body 1 away from the handle air outlet 6 can be increased, so that the wind speed at different positions of the hair dryer air outlet 5 becomes more uniform, and the air flow temperature at different positions of the hair dryer air outlet 5 becomes more uniform, which improves the user experience and reduces the risk of damage to the heating mechanism and the hair dryer due to excessive local temperature.

[0050] refer to Figure 1 , Figure 4 , Figure 6 , Figure 7 In one embodiment, the first notch 3 and the second notch 4 have the same shape and size.

[0051] It can be understood that the shapes and sizes of the first notch 3 and the second notch 4 are consistent, that is, the specifications of the first notch 3 and the second notch 4 are consistent. In this way, there is no need to distinguish between the first notch 3 and the second notch 4 when installing the fixing plate 9 on the support seat body 1, which improves the efficiency of assembling the fixing plate 9 to the support seat body 1.

[0052] refer to Figure 1 , Figure 5-Figure 7 In one embodiment, it further includes a guide portion 7, which is arranged on the inner wall of the accommodating chamber 2, and the guide portion 7 is located on both sides of a first flow channel (not shown in the figure) formed by the first notch 3 and the second notch 4.

[0053] It is worth noting that, by providing the guide portion 7, the vortex effect generated when the airflow flows through the first flow channel can be weakened, thereby reducing the airflow noise generated when the airflow flows through the first flow channel.

[0054] refer to Figure 1 , Figure 5-Figure 7 In one embodiment, the guide part 7 is columnar, and both sides of the first notch 3 and the second notch 4 are provided with the guide part 7, and the guide part 7 is chamfered. The guide part 7 is designed to be columnar, with a simple structure and ingenious design, which can reduce the difficulty of mold opening when the guide part 7 and the support seat body 1 are formed by an integrated molding process.

[0055] refer to Figure 1 , Figure 6 , Figure 7 In one embodiment, the guide portion 7 is a hollow structure. By designing the guide portion 7 as a hollow structure, the wall thickness of the guide portion 7 can be reduced, the risk of excessive shrinkage of the guide portion 7 during injection molding can be reduced, and raw materials can be saved.

[0056] In one embodiment, at least one third notch (not shown) is further provided on the side walls of the support seat body 1 located on both sides of the first flow channel, and the third notch is used to divert the airflow entering from the first notch 3 .

[0057] It can be understood that by setting the third notch, part of the airflow flowing through the handle air outlet 6 directly passes through the first notch 3 and the third notch, thereby reaching the outer periphery of the support base body 1, further improving the uniformity of wind speed at different positions of the hair dryer air outlet 5, and further improving the uniformity of air flow temperature at different positions of the hair dryer air outlet 5.

[0058] refer to Figure 1 , Figure 4-Figure 7 In one embodiment, a support column 8 is respectively provided at the first notch 3 and the second notch 4. The support column 8 at the first notch 3 divides the first notch 3 into two parts evenly, and the support column 8 at the second notch 4 divides the second notch 4 into two parts evenly. The support column 8 is used to fix the fixing plate 9 of the heating mechanism.

[0059] In this embodiment, by providing the support column 8, sufficient support can be provided for the fixing plate 9, thereby avoiding a reduction in the number of fixing plates 9 due to the provision of the first notch 3 and the second notch 4, thereby affecting the supporting effect of the fixing plate 9 on the heating wire. In addition, the support column 8 evenly separates the airflow passing through the first notch 3 and the second notch 4, thereby reducing the risk of increased airflow noise due to uneven separation.

[0061] It is worth noting that by providing the first reinforcing rib 10, the strength of the support column 8 is improved and the risk of the support column 8 breaking or excessive deformation is reduced. At the same time, the first reinforcing rib 10 is equivalent to lengthening the width of the support column 8 along the airflow direction in the first flow channel, thereby reducing the risk of mutual interference between the airflows on both sides of the support column 8. The thickness of the first reinforcing rib 10 is smaller than the thickness of the support column 8, which can reduce the airflow noise when the airflow passes through the support column 8.
