Description

Technical Field

[0001] The present invention relates to the technical field of hair dryers, in particular to a novel hair care hair dryer. Background Art

[0002] Currently, most of the hair care hair dryers on the market use water ion technology, which uses electric ion technology to convert water molecules into water ions, and then sprays the water ions out and delivers them to the hair and scalp under the action of airflow, thereby replenishing hair moisture, reducing hair static electricity, deeply moisturizing hair, improving scalp dryness, making hair smooth and shiny, and protecting the health of the scalp and hair.

[0003] This type of hair dryer has a water ion component installed inside. The water ion component generally includes a condensing rod, an electrode that passes high voltage, and a semiconductor refrigeration plate connected to the condensing rod. The contact between the condensing rod and the cold surface of the semiconductor refrigeration plate creates a temperature difference between the surface of the condensing rod and the surrounding air, thereby forming water droplets on the surface of the condensing rod. Under the action of the electrode, the condensed water is broken up to form water ions. In order to ensure the reliability of water ion formation, it is necessary to ensure the formation of condensed water. Therefore, it is necessary to send an airflow that has not been heated by the heating component (i.e., an airflow close to the ambient temperature, also called a cold airflow) to the condensing rod. Usually, a cold air channel is set in the hair dryer to complete the delivery of the cold airflow. In the water ion hair dryers disclosed in the prior art, the cold air channel and the heating component are set independently, occupying a certain amount of internal space of the hair dryer, which is not conducive to the miniaturization and cost reduction of the product. Especially for I-shaped straight hair dryers, this will result in the product having a larger diameter and a poor grip. Utility Model Content

[0004] In order to solve the technical problem of the large overall volume of hair dryers in the prior art, the utility model provides a new hair care hair dryer, which reduces the volume of the hair dryer by arranging the cold air duct inside the heating component while ensuring the reliable generation of water ions.

[0005] A novel hair care hair dryer includes a housing, a water ion module, a fan unit, and a heating assembly arranged inside the housing. The housing defines an air flow path, and the housing is provided with an air flow inlet and an air flow outlet. External air enters the housing from the air flow inlet, passes through the fan unit and the heating assembly, and is discharged from the air flow outlet.

[0006] In which, the shell is also provided with a storage space for accommodating the water ion module, the air flow outlet is located outside the storage space, the middle part of the heating component includes an insulating rod that defines a cold air channel, the cold air channel receives the cold air flow that is not heated by the heating component, and one end of the insulating rod extends into the storage space and discharges the cold air flow.

[0007] The advantage is that the cold air channel is limited to the heating component, avoiding the need for an additional cold air channel, so that the space inside the heating component can be utilized, effectively saving the radial space of the hair dryer, reducing the product volume, reducing space occupancy, and making it portable and easy to store; the cold air flow that is not heated by the heating component can enter the storage space of the water ion module through the cold air channel, which can cool the water ion module and ensure the reliability of water ion generation.

[0008] Preferably, the shell includes a first shell for forming the accommodating space, and a first assembly hole for assembling with the heat insulation rod is provided below the first shell. The first shell includes a first left shell and a first right shell that are buckled into each other in a horizontal direction, and the first assembly hole is formed when the first left shell and the first right shell are buckled into place.

[0009] The advantages are that the space for the water ion module and the insulation rod defining the cold air channel are assembled, allowing the cold airflow to flow completely into the space, reducing losses during the cold airflow transmission process. By horizontally snapping the first left shell and the first right shell together and forming the first assembly hole after they are in place, assembly difficulty is reduced and assembly efficiency is improved. By locating the first assembly hole below the first shell, the cold airflow transmission path is shortened, reducing airflow losses.

[0010] Preferably, the shell also includes a second shell located outside the first shell and connected to the first shell, and a third shell located outside the second shell, the second shell and the third shell form a first air duct, the air flow heated by the heating component enters the first air duct, and the first air duct extends around the first shell.

[0011] The advantage is that the first air duct extends around the accommodating space, making full use of the internal space of the shell, miniaturizing the product, reducing space occupancy, and making it portable and easy to store.

[0012] Preferably, a second assembly hole for the insulation rod to pass through is provided on the second shell, and the second assembly hole is located below the first assembly hole. A heat insulation cavity is also provided on the second shell, and the second assembly hole passes through the heat insulation cavity.

[0013] The advantage is that this arrangement allows the insulation rod to pass through the insulation cavity. Through the arrangement of the insulation cavity, on the one hand, the possibility of the temperature increase of the cold air flow in the insulation rod caused by the hot air flow entering the first air duct is reduced, and the air outlet end of the insulation rod is located in the insulation cavity, which reduces the possibility of the temperature increase of the cold air flow in the insulation rod caused by the heat radiation of the heating component; on the other hand, it effectively separates the water ion module from the heating component to play an insulating role, thereby ensuring the reliability of water ion generation.

[0014] Preferably, the second shell includes a bottom wall close to the heating component, and a first wall extending from the outside of the second assembly hole downward from the bottom wall and toward the insulation rod, the first wall is arranged around the second assembly hole, the first wall and the bottom wall define the insulation cavity, the first wall is a downwardly protruding arc wall, and the first wall guides the airflow to the first air duct.

[0015] The advantage is that the curved wall of the heat-insulating cavity has a guiding effect on the airflow, which can guide the airflow to the first air duct and reduce airflow loss.

[0016] Preferably, the side wall defining the first assembly hole on the first shell is in close contact with the side wall of the insulation rod, and one of the wall defining the second assembly hole and the insulation rod is provided with a first convex stop, and the other is provided with a first concave stop that cooperates with the first convex stop.

[0017] The advantage is that, through the cooperation of the first convex stop and the first concave stop, the second assembly hole and the insulation rod form a double-stop sealing structure, and at the same time, the side wall of the first assembly hole defined by the first shell is tightly attached to the side wall of the insulation rod, thereby enhancing the sealing performance. In the process of the cold air flow passing through the second shell and the first shell to reach the accommodating space of the water ion module, the loss of the cold air flow is reduced, thereby achieving the purpose of cooling the water ion module and improving the working efficiency of the water ion module.

[0018] Preferably, the first shell also has a water ion outlet connecting the outside and the accommodating space, the water ion outlet is arranged in the same direction as the air flow outlet, the air flow outlet is located on both sides of the accommodating space in the vertical direction, and the water ion outlet is located in the middle of the air flow outlet.

[0019] The advantage is that the water ion outlet and the air flow outlet are set in the same direction, which can replenish moisture and negative ions to the hair while drying it, transforming dry scalp and making hair smooth and shiny.

[0020] Preferably, the housing further includes a control assembly, which is located upstream of the heating assembly. The water ion module is electrically connected to the control assembly via a wire, which passes through the insulation rod.

[0021] The advantage is that the wires pass through the insulation rod, avoiding the need for additional wiring space for the water ion module in the internal space of the hair dryer, improving space utilization, saving installation space, reducing the radial size of the hair dryer, and facilitating product miniaturization.

[0022] Preferably, the heat-insulating rod and the heating assembly have the same axis, and the heat-insulating rod and the fan unit are coaxially arranged.

[0023] The advantage is that this setting method can make the wind outlet of the cold air channel in the insulation rod uniform, and by coaxially arranging the insulation rod and the fan unit, the flow path of the wires connecting the water ion module and the control component is reduced, saving installation space, and reducing the internal volume of the hair dryer without affecting the power of the hair dryer.

[0024] Preferably, the hair dryer is cylindrical, and the shell further includes a cylindrical outer shell and a decorative part. The first shell, the second shell, and the third shell are all arranged inside the outer shell. The decorative part is located on the outside of the air flow outlet, and the decorative part is fixedly connected to the third shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0037] like Figure 1-10 As shown, a novel hair care hair dryer includes a housing, a water ion module 10 arranged inside the housing, a fan unit 7 and a heating assembly 8. The housing defines an air flow path, and the housing is provided with an air flow inlet 2 and an air flow outlet 301. External air enters the housing from the air flow inlet, passes through the fan unit 7 and the heating assembly 8, and is discharged from the air flow outlet 301.

[0038] In which, the shell is also provided with a storage space 20 for accommodating the water ion module 10, the air flow outlet 301 is located outside the storage space 20, and an insulation rod 9 is provided in the middle of the heating component 8. The insulation rod 9 defines a cold air channel 3021 for receiving the cold air flow that is not heated by the heating component 8. One end of the insulation rod 9 extends into the storage space 20 and discharges the cold air flow.

[0039] In the above technical solution, the cold air flows through the insulating rod 9 into the accommodating space 20 to cool the water ion module 10. The cold air channel is set in the hollow area of ​​the insulating rod 9 and only receives the cold air flow. In addition, the insulating rod 9 is made of scalding-proof material.

[0040] In the above technical solution, if Figure 5As shown, the housing also includes a first housing 4 for forming the accommodating space 20. A first assembly hole 403 is provided below the first housing 4 for assembly with the thermal insulation rod 9. Furthermore, in this example, the first housing includes a first left housing 401 and a first right housing 402, which interlock horizontally, enhancing the structural tightness through interlocking. The first left housing 401 and the first right housing 102 are not limited to snap-fit ​​fastening; other assembling methods may also be employed, which can facilitate a compact structure and enable rapid assembly of the accommodating space 20 of the water ion module 10.

[0041] Further, such as Figure 4 、 5 As described above, the first left shell 401 and the first right shell 402 are buckled into place to form a first assembly hole 403 . The first assembly hole 403 is located below the first shell and is assembled with the top 903 of the heat insulation rod.

[0042] like Figure 2 、 5 As shown in , 6 and 8, the shell also includes a second shell 5 located outside the first shell 4 and connected thereto, and a third shell 11 located outside the second shell 5. A first air duct 13 is formed between the second shell 5 and the third shell 11. The air flow heated by the heating component 8 enters the first air duct 13. The first air duct 13 extends around the first shell 4.

[0043] It can be understood that the airflow heated by the heating assembly 8 enters the first air duct 13 through the hot air channel 3011 .

[0044] Further, such as Figure 7 As shown, the air flow outlet 301 is an air outlet gap formed between the second shell 5 and the third shell 11 .

[0045] Further, such as Figure 6 、 8 As shown in Figures 9 and 9, the third housing 11 further includes a curved plate 101. The second housing 5 is provided with a first groove 506 extending in an arc shape from bottom to top. The curved plate 101 is fixed to the first groove 506. The curved plate 101 can redirect the airflow flowing along the axis of the housing assembly and discharge it from the airflow outlet 301, so that the airflow in the first air duct 13 is discharged from the airflow outlet 301. The curved plate 101 serves as a flow guide, reducing noise and airflow loss. It is understood that there are multiple curved plates 101, which are arranged at intervals.

[0046] like Figure 4 、 6As shown, a second assembly hole 503 is provided on the second shell 5 for the insulation rod 9 to pass through, and the second assembly hole 503 is located below the first assembly hole 403. An insulation cavity 505 is also provided on the second shell 5, and the second assembly hole 503 passes through the insulation cavity 505.

[0047] Further, such as Figure 4 、 6 As shown in Figure 9, the second shell 5 also includes a bottom wall 504 close to the heating component 8, and a first wall 507 extending from the outside of the second assembly hole 503 downward from the bottom wall 504 and toward the direction close to the insulation rod 9. The first wall 507 is arranged around the second assembly hole 503. The first wall 507 and the bottom wall 504 define the insulation cavity 505. The first wall 507 is an arc-shaped wall protruding downward, and the first wall 507 guides the airflow to the first air duct 13.

[0048] Further, such as Figure 3 、 4 As shown, the insulation cavity 505 is located between the heating component 8 and the accommodating space 20 of the water ion module 10. The airflow heated by the heating component 8 blows directly to the bottom of the insulation cavity 505. The lower part of the insulation cavity 505 is a first wall 507. The first wall 507 is a downwardly protruding arc wall. The airflow can be more smoothly guided to the first air duct 13 on both sides of the water ion module 10 through the arc wall, and the insulation cavity 505 can isolate the heat of the airflow from being transferred to the insulation rod 9, reducing the possibility of the temperature of the cold airflow in the insulation rod rising due to the heat radiation of the heating component; and by separating the heating component and the water ion module, the reliability of the water ion module is improved.

[0049] like Figure 4 As shown, the side wall of the first assembly hole defined on the first shell is in close contact with the side wall of the insulation rod, and one of the wall defining the second assembly hole 503 and the insulation rod 9 is provided with a first convex stop 14, and the other is provided with a first concave stop 15 that cooperates with the first convex stop 14.

[0050] Furthermore, the first convex stop 14 is arranged on the wall surface that defines the second assembly hole 503, and the first concave stop 15 is arranged on the outer wall surface of the insulation rod 9. The first convex stop 14 includes two, and the first concave stop 15 also includes two, both of which are arranged vertically up and down. The first convex stop 14 is respectively arranged on the first wall 507 and the bottom wall 504 of the second shell 5.

[0051] It can be understood that the positions of the first convex stop 14 and the first concave stop 15 can be interchanged.

[0052] Further, such as Figure 4 、 6As shown, a second concave stop 16 is provided on the bottom wall 504 of the second housing 5 or one of the third housing 11, and a second convex stop 17 is provided on the third housing 11 to cooperate with the second concave stop 16. The second concave stop 16 is provided on the bottom wall 504 of the second housing 5 and is located next to the junction of the bottom wall 504 and the first wall 507. The second convex stop 17 is provided on the third housing 11 near the first wall 507.

[0053] Further, such as Figure 4 、 7 As described, one of the outer wall of the second shell 5 and the inner wall of the third shell 11 is provided with a second concave stop 16, and the other is provided with a second convex stop 17 that cooperates with the second concave stop 16; more specifically, the second convex stop 17 includes four, and the second concave stop 16 includes four, of which two second convex stops 17 and two concave stops 16 are arranged at the bottom wall of the second shell, and the other two second convex stops 17 and two concave stops 16 are arranged at the side wall of the second shell 5 close to the third shell 11.

[0054] Further, such as Figure 6 As shown, the second shell 5 includes a second left shell 501 and a second right shell 502 . The second left shell 501 and the second right shell 502 are buckled together in a horizontal direction, and a second assembly hole 503 is formed after the two are buckled together.

[0055] Further, such as Figure 7 As described above, the first shell 4 has a third convex stop 23 at the joint between the first left shell 401 and the first right shell 402, and the second shell 5 has a third concave stop 24 that cooperates with the third convex stop 23. It is precisely the cooperation between the third convex stop 23 and the third concave stop 24 that achieves the effect of the second shell 5 wrapping around the first shell 4 and being fixed to the central annular area formed by the second shell 5. It is understandable that the positions of the third convex stop 23 and the third concave stop 24 can be interchanged.

[0056] Further, such as Figure 1 As shown, the first shell 4 also has a water ion outlet 302 connecting the outside and the accommodating space 20. The water ion outlet 302 is arranged in the same direction as the air flow outlet 301. The air flow outlet 301 is located on both sides of the accommodating space 20 in the vertical direction, and the water ion outlet 302 is located in the middle of the air flow outlet 301.

[0057] like Figure 2 、 3As shown, the housing further includes a control component 6, which is located upstream of the heating component 8. The water ion module 10 is electrically connected to the control component 6 via a wire, and the wire passes through the heat-insulating rod 9. The control component 6 can be located between the heating component 6 and the fan unit 7, or it can be located upstream of the fan unit 7. "Upstream" means that according to the flow direction of the airflow in the housing, the component that the airflow passes through first is upstream of the component that the airflow passes through later. In this example, Figure 2 As shown, along the direction of air flow, the control component 6, the fan unit 7, the heating component 8, and the water ion module 10 are arranged in sequence.

[0058] The heat-insulating rod 9 and the heating assembly 8 have the same axis, and the heat-insulating rod 9 is coaxially arranged with the fan unit 7. It can be understood that the heat-insulating rod 9, the heating assembly 8, and the fan unit 7 are located on the same axis.

[0059] like Figure 1 、 2 As shown in Figure 10 , the hair dryer further includes a decorative member 19 , which is located on the outside of the airflow outlet 301 and is fixedly connected to the third shell 11 .

[0060] Furthermore, the decorative sheet 19 has a circular runway design, and the airflow outlets 301 are located at both ends of the decorative sheet 19. The decorative sheet 19 is provided with a first protruding buckle 1901, and the third housing 11 has a first buckle position 1902 for the first protruding buckle 1901 to be assembled. The first protruding buckle 1901 is assembled with the first buckle position 1902, thereby firmly connecting the assembly 19 and the third housing 11. Furthermore, there are multiple first protruding buckles 1901 and first recessed buckles 1902, which are arranged on both sides of the airflow outlet 301.

[0061] Further, such as Figure 2 、 4 As shown in Figures 10 and 10, the housing further comprises an outer shell 1 and a top cover 21. The first shell 4, the second shell 5, and the third shell 11 are disposed within the outer shell 1. The top cover 21 is fixedly connected to the upper end of the third shell 11. A second buckle 2101 is provided on the top cover. The top cover 21 is mounted above the hair dryer. A second buckle 2102 is provided on the top of the third shell 11 to mate with the second protruding buckle 2101. The second protruding buckle 2101 is fixedly connected to the second buckle 2102. The upper end of the outer shell 1 is open, and the top cover 21 is fixedly connected to the third shell 11 to close the upper end opening of the outer shell 1.

[0062] It is understandable that the housing 1 can also be a columnar structure with a closed top and an open bottom, and the housing 1 can be put on the outside of the first shell 4, the second shell 5, and the third shell 11 from top to bottom.
