Description

Technical Field

[0001] This application relates to the field of hair dryer technology, and particularly to a hair dryer. Background Technology

[0002] After washing their hair, whether it's naturally drying or using a low-speed hairdryer, it takes a lot of time to dry it before bed or when going out. High-speed hairdryers make life much easier, shortening the time it takes to dry hair. Currently, to produce air at different temperatures, high-speed hairdryers typically consist of a heating element and a small fan. If only the fan is running and the heating element is not working, the high-speed hairdryer can only blow cold air. However, when the heating element and the fan are working simultaneously, the heating element assembly generates heat, and the air blown by the fan is turned into hot air after passing through the heating element.

[0003] Currently, the heating element of high-speed hair dryers is generally located in the blower head, while the control harness of the heating element is generally laid in the inner shell of the blower head and finally connected to the control board located in the handle. The control harness laid in the inner shell of the blower head will obstruct the airflow. The airflow will generate turbulence when passing through the control harness, affecting the airflow speed after it is blown out of the air outlet, and will also increase the airflow noise. Utility Model Content

[0004] To address the aforementioned problems, this application provides a hair dryer with an ingenious design and simple structure. This application utilizes a first wire-passing hole located on the side of the first housing away from the annular air outlet to directly lead the wiring harness inside the hair dryer head to the outside of the first housing, forming an external wiring method. This avoids the wiring harness inside the hair dryer head obstructing airflow, reducing airflow turbulence and noise. The technical solution adopted in this application is as follows:

[0005] A hair dryer, comprising:

[0006] A hair dryer head includes a first housing and a heating element. The first housing has a first receiving cavity, and the heating element is disposed within the first receiving cavity. The first housing has an annular air outlet, and a first wire passage hole is provided on the side of the first housing away from the annular air outlet. A handle includes a second housing, a wind-generating element, and a control board. The second housing has a second receiving cavity, and both the wind-generating element and the control board are disposed within the second receiving cavity, with the control board located at the end of the second housing. The wiring harnesses of the components in the first housing are led out from the first receiving cavity through the first wire passage hole and led along the outer wall of the second housing to the control board.

[0007] By providing a first wire hole on the side of the first housing away from the annular air outlet, the wire harness inside the blower head is directly led out to the outside of the first housing, forming a wiring method of inner housing and outer wiring. This avoids the wire harness obstructing the airflow after being laid inside the first housing. Laying the wire harness outside the first housing can reduce the turbulence effect and airflow noise of the airflow.

[0008] In some embodiments, the first housing is further provided with a first wiring groove on the side away from the annular air outlet, and the first wiring groove is disposed adjacent to the first wire passage hole; the wire bundle led out from the first wire passage hole is led out along the first wiring groove to the outer wall of the second housing.

[0009] By setting the first wiring groove, the wire harness led out from the first wire hole is laid along the first wiring groove, so that the wire harness is distributed in an orderly manner in a preset direction, avoiding the wire harness being squeezed when the outer shell of the blower head is fastened to the first housing (inner shell), thereby reducing the risk of the wire harness being squeezed and damaged.

[0010] In some embodiments, the first wiring groove is provided with a first partition, and the wires leading out from the first wire hole are separated by the first partition.

[0011] By setting a first partition in the first cable tray, the wire bundle leading out from the first cable hole can be divided into several strands, reducing the risk of the strands getting tangled (intertwined), avoiding messy distribution of the wire bundles, and improving the neatness of the wiring.

[0012] In some embodiments, there are at least two first partitions, and the two first partitions are spaced apart along the width direction of the first wiring groove, so that at least a portion of the wires leading out from the first wire hole can be clamped between the groove wall of the first wiring groove and the adjacent first partition.

[0013] By clamping at least a portion of the wire harness between the wall of the first wiring groove and the first partition, the wire harness is bound within the first wiring groove, preventing the wire harness from moving and thus reducing the risk of squeezing the wire harness when the outer shell is fastened to the first housing.

[0014] In some embodiments, the second housing is provided with a wire-holding groove at one end near the blower head. The wire-holding groove is arranged circumferentially along the outer wall of the second housing and is used to hold the wire harness led out from the first wire hole.

[0015] By setting the wire-holding groove, the wire harness led out from the first wire hole can be orderly held in the wire-holding groove, thereby completing the circumferential layout of the wire harness along the second housing and avoiding the wire harness being squeezed when the handle outer shell is fastened to the second housing (handle inner shell).

[0016] In some embodiments, the second housing is further provided with an arc-shaped turning groove at one end near the blower head, and the wire harness led out from the first wire hole first passes through the arc-shaped turning groove and then through the wire clamping groove.

[0017] By setting an arc-shaped turning groove, the wire harness led out from the first wire hole can smoothly enter the wire clamping groove. The arc-shaped turning groove plays a role in smooth transition and reduces the risk of damage to the wire harness due to bending.

[0018] In some embodiments, the second housing has a second wire hole at one end near the blower head. The second wire hole communicates with the second receiving cavity and is located on the same side of the blower as the annular air outlet. The wiring harness of the air-generating component is led out from the second receiving cavity through the second wire hole and along the outer wall of the second housing to the control panel.

[0019] By setting a second wire guide hole, which is designed to follow the direction of the wire harness connected to the air generating component, the risk of the air generating component moving or becoming misaligned due to sharp bending of the wire harness is avoided, thereby reducing the vibration intensity or vibration noise generated by the air generating component during operation.

[0020] In some embodiments, a second wiring groove is provided on the outside of the second housing, and the second wiring groove is arranged along the length direction of the second housing.

[0021] By setting a second wiring channel, the wiring harness in the blower head and the wiring harness of the air generating component can be neatly arranged on the outside of the second housing (handle inner housing), avoiding compression of the wiring harness when the handle outer housing is fastened to the second housing.

[0022] In some embodiments, there are at least two second wiring channels, and the two second wiring channels are arranged circumferentially spaced along the second housing.

[0023] By arranging two second wiring channels at intervals along the circumference of the second housing, the wiring harness in the blower head and the wiring harness of the air-generating component can be respectively arranged in the two spaced second wiring channels. This can avoid mutual interference between the wiring harness in the blower head and the wiring harness of the air-generating component, and improve the functional stability of the blower.

[0024] In some embodiments, the second housing is provided with a cable guide window, the position of which corresponds to the control board, and the second cable routing groove communicates with the cable guide window.

[0025] By setting up a wire guide window, sufficient space is provided for the wire harness to pass through, which helps to improve the efficiency of the wire harness passing through the second wiring channel into the second receiving cavity and finally connecting to the control board.

Laying the wire harness outside the first housing can reduce the turbulence effect and airflow noise of the airflow.

[0028] 2. The hair dryer provided in this application provides a first wiring groove, in which the wire harness led out from the first wire hole is laid along the first wiring groove, so that the wire harness is distributed in an orderly manner in a preset direction, avoiding the wire harness being squeezed when the outer shell of the hair dryer is fastened to the first shell (inner shell), thereby reducing the risk of the wire harness being squeezed and damaged.

[0030] 4. The hair dryer provided in this application binds the wire harness in the first wiring groove by clamping at least part of the wire harness between the groove wall of the first wiring groove and the first partition, thereby preventing the wire harness from moving and reducing the risk of squeezing the wire harness when the outer shell is fastened to the first housing.

[0031] 5. The hair dryer provided in this application, by setting a wire-holding groove, allows the wire harness led out from the first wire hole to be orderly held in the wire-holding groove, thereby completing the circumferential arrangement of the wire harness along the second housing, and avoiding the wire harness being squeezed when the handle housing is fastened to the second housing (handle inner housing).

[0032] 6. The hair dryer provided in this application, by setting an arc-shaped turning groove, allows the wire harness led out from the first wire hole to smoothly enter the wire clamping groove.

[0047] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0048] refer to Figures 1-3 This application provides a hair dryer, including: a hair dryer head 1, which includes a first housing 2 and a heating element. The first housing 2 has a first receiving cavity, and the heating element is disposed in the first receiving cavity. The first housing 2 has an annular air outlet 5, and a first wire passage hole 6 is provided on the side of the first housing 2 away from the annular air outlet 5; a handle 3, which includes a second housing 4, a wind-generating component, and a control board 7. The second housing 4 has a second receiving cavity, and the wind-generating component and the control board 7 are both disposed in the second receiving cavity, with the control board 7 located at the end of the second housing 4; the wire harnesses of each component in the first housing 2 are led out from the first receiving cavity through the first wire passage hole 6 and led along the outer wall of the second housing 4 to the control board 7.

[0049] Specifically, the finished hair dryer includes a blower head 1 and a handle 3. The blower head 1 includes an outer shell and an inner shell, where the inner shell is the first housing 2. The handle 3 includes a handle outer shell and a handle inner shell, where the handle inner shell is the second housing 4. The air-generating components inside the second housing 4 include a motor and an impeller, preferably a brushless high-speed motor. In one embodiment, the tail end of the second housing 4 is the air inlet of the entire hair dryer. After the airflow enters the second receiving cavity from the tail end of the second housing 4, it is guided along the second receiving cavity into the first housing 2, i.e., into the first receiving cavity. Then, the airflow is heated by the heating element and finally blown out from the annular air outlet 5.

[0050] It is understandable that by setting a first wire hole 6 on the side of the first housing 2 away from the annular air outlet 5, the wire harness inside the blower head 1 is directly led out to the outside of the first housing 2, forming a wiring method of inner housing and outer wiring. This avoids the wire harness from obstructing the airflow after being laid inside the first housing 2. Laying the wire harness outside the first housing 2 can reduce the turbulence effect and airflow noise of the airflow.

[0051] refer to Figure 1 In one embodiment, the first housing 2 is further provided with a first wiring groove 8 on the side away from the annular air outlet 5, and the first wiring groove 8 is arranged adjacent to the first wire passage hole 6; the wire harness led out from the first wire passage hole 6 is led out along the first wiring groove 8 to the outer wall of the second housing 4. By providing the first wiring groove 8, the wire harness led out from the first wire passage hole 6 is arranged along the first wiring groove 8, so that the wire harness is distributed in an orderly manner in a preset direction, avoiding the compression of the wire harness when the outer shell of the blower head 1 is fastened to the first housing 2 (inner shell), thereby reducing the risk of the wire harness being compressed and damaged.

[0052] Understandably, reference Figure 1 A first dividing part 9 can be provided in the first wiring groove 8, and the wire bundles led out from the first wire hole 6 are separated by the first dividing part 9. By providing the first dividing part 9 in the first wiring groove 8, the wire bundles led out from the first wire hole 6 can be divided into several strands, reducing the risk of the strands of wire bundles tangling (crossing), avoiding messy distribution of wire bundles, and improving the neatness of the wiring.

[0053] refer to Figure 1 In one embodiment, there are at least two first partitions 9, and the two first partitions 9 are spaced apart along the width direction of the first wiring groove 8, so that at least a portion of the wire harness leading out from the first wire hole 6 can be clamped between the groove wall of the first wiring groove 8 and the adjacent first partition 9. It is easy to understand that by clamping at least a portion of the wire harness between the groove wall of the first wiring groove 8 and the first partition 9, the wire harness is restrained within the first wiring groove 8, preventing the wire harness from moving, thereby reducing the risk of squeezing the wire harness when the outer shell is fastened to the first housing 2.

[0054] refer to Figure 1 , Figure 2 In one embodiment, the second housing 4 is provided with a wire-holding groove 10 at one end near the blower head 1. The wire-holding groove 10 is arranged circumferentially along the outer wall of the second housing 4 and is used to hold the wire harness led out from the first wire hole 6.

[0055] It is worth noting that by setting the wire-holding groove 10, the wire harness led out from the first wire hole 6 can be orderly held in the wire-holding groove 10, thereby completing the circumferential arrangement of the wire harness along the second housing 4, and avoiding the wire harness being squeezed when the handle housing is fastened to the second housing 4 (handle inner housing).

[0056] To ensure that the wire harness leading out from the first wire hole 6 can smoothly enter the wire slot 10, refer to Figure 1 In one embodiment, the second housing 4 is further provided with an arc-shaped turning groove 11 at the end near the blower head 1. The wire harness led out from the first wire hole 6 first passes through the arc-shaped turning groove 11 and then through the wire clamping groove 10. By setting the arc-shaped turning groove 11, the wire harness led out from the first wire hole 6 can smoothly enter the wire clamping groove 10. The arc-shaped turning groove 11 plays a smooth transition role, reducing the risk of damage to the wire harness due to bending.

[0057] refer to Figure 2 , Figure 3 In one embodiment, the second housing 4 has a second wire passage hole 12 at one end near the blower head 1. The second wire passage hole 12 communicates with the second receiving cavity and is located on the same side of the blower as the annular air outlet 5. The wiring harness of the air-generating component is led out from the second receiving cavity through the second wire passage hole 12 and led along the outer wall of the second housing 4 to the control plate 7. By providing the second wire passage hole 12, which is arranged to conform to the direction of the wiring harness connected to the air-generating component, the risk of the air-generating component moving or misaligning due to sharp bending of the wiring harness is avoided, thereby reducing the vibration intensity or vibration noise generated by the air-generating component during operation.

[0058] refer to Figure 2 , Figure 3 In one embodiment, a second wiring groove 13 is provided on the outside of the second housing 4, and the second wiring groove 13 is arranged along the length direction of the second housing 4. By providing the second wiring groove 13, the wiring harness in the blower head 1 and the wiring harness of the air generating component can be neatly arranged on the outside of the second housing 4 (handle inner housing), avoiding compression of the wiring harness when the handle outer housing is fastened to the second housing 4.

[0059] Preferably, refer to Figure 3There are at least two second wiring channels 13, and the two second wiring channels 13 are arranged circumferentially around the second housing 4. It should be noted that by arranging the two second wiring channels 13 circumferentially around the second housing 4, the wiring harness in the blower head 1 and the wiring harness of the air generating component can be respectively arranged in the two spaced second wiring channels 13. This can avoid mutual interference between the wiring harness in the blower head 1 and the wiring harness of the air generating component, and improve the functional stability of the blower.

[0060] refer to Figure 3 In one embodiment, the second housing 4 is provided with a wire passage window 14, the position of which corresponds to the control board 7. The second wiring groove 13 communicates with the wire passage window 14. The wire harness in the blower head 1 and the wire harness of the air generating component pass through the wire passage window 14 from the second wiring groove 13 into the second receiving cavity and are finally connected to the control board 7. By setting the wire passage window 14, sufficient space is provided for the wire harness to pass through, which helps to improve the efficiency of the wire harness passing through the second wiring groove 13 into the second receiving cavity and finally connecting to the control board 7.

[0061] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
