Description

Technical Field

[0001] This utility model relates to the field of hair care equipment technology, and in particular to a hot air comb. Background Technology

[0002] Hot air combs, used for drying and styling hair, generally include a handle assembly and an air outlet assembly that can rotate at a certain angle on the handle assembly. The handle assembly houses a fan and a heating element, causing airflow to be heated from the lower end of the handle assembly and guided towards the air outlet assembly. To improve the user experience, some hot air combs also incorporate a water ion module within the handle assembly. This module collects moisture from the airflow, cools it, and ionizes it into water ions before it flows out from the handle assembly. However, this water ion module is typically installed inside the handle assembly, making the overall structure bulky. Furthermore, the proximity of the water ion module to the heating element can shorten its lifespan. Additionally, the steam outlet of the water ion module needs to follow a relatively long channel to exit the air outlet assembly, potentially affecting its efficiency. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, a hot air comb is provided, which aims to make the overall structure simpler and more compact, and the handle will not be constructed into a bulky structure due to the large number of internal components. At the same time, the water ion generator is far away from the heating components, so that its service life is longer and its performance is not easily affected by long-term heating, thereby overcoming at least one of the above-mentioned technical defects.

[0004] The specific technical solution is as follows:

[0005] A hot air comb includes a handle with an air inlet and an air outlet head rotatably connected to the upper end of the handle and having an air outlet, which causes the hot air comb to be in a straight or curved state.

[0006] The handle is also equipped with a fan assembly to guide the airflow from the air inlet to the air outlet, and a heating assembly to heat the airflow. The air outlet is also equipped with a water ion generator to collect the moisture in the airflow and generate water ions, which are then sprayed out towards the air outlet.

[0007] Preferably, the handle has a first airflow channel connected to the air inlet, and the air outlet has a second airflow channel connected to the air outlet. When the hot air comb is in a straight or curved state, the first airflow channel and the second airflow channel are connected.

[0008] Preferably, the upper end face of the handle forms a first inclined surface, and the lower end face of the air outlet forms a second inclined surface that matches the first inclined surface. At least two locking holes are provided on the second inclined surface, and a latch is slidably provided on one side of the handle. The upper end of the latch forms a latch tongue that can pass through the through groove on the second inclined surface and extend into one of the locking holes, so that the air outlet and the handle are kept locked together.

[0009] Preferably, the first inclined surface has a first opening that forms the air outlet end of the first airflow channel, the second inclined surface has a second opening that forms the air inlet end of the second airflow channel, and a connecting ring is also formed protruding around the first opening on the first inclined surface. The inner peripheral wall of the second opening has an annular groove that matches the connecting ring, so that the air outlet can be rotatably mounted on the handle.

[0010] Preferably, within the first airflow channel, along the flow path of the airflow, the heating element is arranged downstream of the fan assembly, and a circuit board is also embedded in the inner wall of the first airflow channel. The heating element, the fan assembly, and the water ion generator are electrically connected to the circuit board.

[0011] Preferably, the handle includes an outer cylinder and an inner cylinder nested together. The lower end of the outer cylinder has a grid structure on its wall, and the grid holes on the grid structure serve as air inlets. The lower end of the inner cylinder is connected to a filter component that is directly opposite the grid structure.

[0012] Preferably, the air outlet includes an inner shell that forms a second airflow channel, an outer shell that is fitted around the outer periphery of the inner shell, and a push knob that is slidably provided on one side of the inner shell for engaging the accessory head.

[0013] The beneficial effects of the above technical solution are as follows:

[0014] The hot air comb includes a rotatable handle and an air outlet, allowing the air outlet to be rotated and adjusted to different usage states. The fan assembly and heating assembly are located inside the handle, while the water ion generator is located inside the air outlet, making the overall structure simpler and more compact. The handle will not be bulky due to a large number of internal components. At the same time, the water ion generator is located away from the heating assembly, which extends its service life and makes it less likely to be affected by prolonged heating.

[0021] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the following embodiments are described in detail with reference to the accompanying drawings. And the following definitions are provided: Figure 2 The direction from the power cord to the air outlet shown is the bottom-up direction in this embodiment.

[0022] See Figures 1 to 6 As shown in the figure, the hot air comb provided in this embodiment includes a handle 1 with an air inlet 14 and an air outlet 2 rotatably connected to the upper end of the handle 1 and having an air outlet 24, which causes the hot air comb to be in a straight or curved state; wherein,

[0023] The handle 1 is also equipped with a fan assembly 3 for guiding the airflow from the air inlet 14 to the air outlet 24, and a heating assembly 4 for heating the airflow. The air outlet 2 is also equipped with a water ion generator 5 for collecting moisture in the airflow and generating water ions, which are then sprayed out towards the air outlet 24.

[0024] Based on the above technical solution, the hot air comb includes a handle 1 and an air outlet 2 that are rotatably connected, so that the air outlet 2 can be rotated to adjust to different usage states. The fan assembly 3 and the heating assembly 4 are set inside the handle 1, and the water ion generator 5 is set inside the air outlet 2, making the overall structure simpler and more compact. The handle 1 will not be constructed into a bulky structure due to the large number of internal components. At the same time, the water ion generator 5 is far away from the heating assembly 4, which makes its service life longer and less likely to be affected by long-term heating.

[0025] In a preferred embodiment, the handle 1 has a first airflow channel connected to the air inlet 14, and the air outlet 2 has a second airflow channel connected to the air outlet 24. When the hot air comb is in a straight or curved state, both the first and second airflow channels are connected. Furthermore, the upper surface of the handle 1 forms a first inclined surface 13, and the lower surface of the air outlet 2 forms a second inclined surface 23 adapted to the first inclined surface 13. At least two locking holes 26 are provided on the second inclined surface 23. A latch 16 is slidably provided on one side of the handle 1. The latch 16 forms a locking tongue at its upper end and can pass through a slot on the second inclined surface 23 and extend into one of the locking holes 26, thus keeping the air outlet 2 and the handle 1 locked together. That is, the latch 16 and the lock hole 26 can keep the air outlet 2 in a state after rotating at a certain angle relative to the handle 1, including a state in which the two are arranged in a straight line, a state in which they are arranged in an "L" shape, and a state in which they are bent at other angles. The specific arrangement can be determined based on the number and relative position of the lock holes 26. For example, four lock holes 26 are arranged in a ring evenly, so that the air outlet 2 can rotate and lock in the directions of 90 degrees, 190 degrees, 270 degrees, and 360 degrees, but it is not limited to this.

[0026] As a further preferred embodiment, combined with Figure 4 As shown, the first inclined surface 13 has a first opening 15 that forms the air outlet end of the first airflow channel, and the second inclined surface 23 has a second opening 25 that forms the air inlet end of the second airflow channel. A connecting ring 131 is also formed protruding around the first opening 15 on the first inclined surface 13. The inner peripheral wall of the second opening 25 has an annular groove 232 that matches the connecting ring 131, so that the air outlet 2 can be rotatably mounted on the handle 1. Its rotatable connection structure can also be achieved by, for example, a tubular connection or an annular stop connection structure designed on the inclined surface, and is not limited to these.

[0027] In a preferred embodiment, specifically as follows: Figures 3 to 6 As shown, within the first airflow channel, along the airflow path, the heating element 4 is arranged downstream of the fan assembly 3, and a circuit board 6 is embedded in the inner wall of the first airflow channel. The heating element 4, fan assembly 3, and water ion generator 5 are electrically connected to the circuit board 6. Furthermore, the handle 1 and the air outlet 2 together form a gas flow channel. One end of the gas flow channel extends to the upper surface of the air outlet 2, and the other end extends to the position between the heating element 4 and the fan assembly 3. The water ion generator 5 is disposed in the gas flow channel, allowing airflow that has not been heated by the heating element 4 to enter the gas flow channel. This ensures that the airflow passing through the water ion generator 5 is cold air, improving its working efficiency and service life.

[0028] In a further preferred embodiment, the handle 1 includes a nested outer cylinder 11 and an inner cylinder 12. The hollow structure of the inner cylinder 12 serves as a first airflow channel. At least one third airflow channel is also formed between the outer wall of the heating element 4 and the inner wall of the inner cylinder 12. The third airflow channel extends upward to the first inclined surface 13 and forms an air outlet 17. The air outlet 2 includes an inner shell 22 that forms a second airflow channel and an outer shell 21 that is sleeved around the outer periphery of the inner shell 22. A connection is formed between the inner shell 22 and the outer shell 21 with the first airflow channel. A fourth airflow channel is isolated from the second airflow channel. The water ion generator 5 is installed in the fourth airflow channel. One end of the fourth airflow channel extends to the second inclined surface 23 and forms at least one air inlet 27 adapted to the air outlet 17. The other end of the fourth airflow channel extends to the upper surface of the air outlet 2 and forms a steam outlet 28 adjacent to the air outlet 24. In a straight or curved state, at least one air outlet 17 is connected to at least one air inlet 27. The gas flow channel is formed by the third airflow channel and the fourth gas flow channel.

[0029] Based on the above, in each usage state, the water ion generator 5 can be located in an independent airflow channel composed of the third airflow channel and the fourth airflow channel. The third airflow channel is surrounded by the outer wall of the housing of the heating component 4 and the inner wall of the inner cylinder 12. On the one hand, the third airflow channel is connected to the upstream of the first airflow channel to ensure that the airflow can enter. On the other hand, it prevents the airflow heated by the heating component 4 from entering and damaging the working performance of the water ion generator 5.

[0030] It is worth noting that the water ion generator 5 typically includes a condenser rod, a thermoelectric cooler, a heat dissipation unit, and a discharge electrode assembly. The cooling surface of the thermoelectric cooler is in contact with the condenser rod, and the heating surface of the thermoelectric cooler is in contact with the heat dissipation unit. The thermoelectric cooler is used to collect water molecules in the airflow, cool them, and cause them to condense. The discharge electrode assembly discharges to the condenser rod to form water ions. This is an existing structure, so further elaboration is omitted here.

[0031] In addition, a push button 201 for engaging accessory heads, including nozzles and comb heads, is slidably provided on one side of the inner housing 22, allowing them to be inserted into the gap formed between the outer housing 21 and the inner housing 22 and engaged with the push button 201. A control panel and a power switch, which are electrically connected to the circuit board 6, are also embedded on the outer cylinder 11 of the handle 1. A power connector for connecting to external AC power is also provided at the bottom of the handle 1, and the housing of the heating element 4 is a heat-insulating housing. These are common components in this invention, so detailed descriptions are omitted here.

[0032] As a further preferred embodiment, combined with Figure 3 and Figure 5As shown, a grid structure 18 is formed on the lower end of the outer cylinder 11. The grid holes on the grid structure 18 serve as air inlets 14. The lower end of the inner cylinder 12 is connected to a filter component 19 facing the grid structure 18 to filter the incoming air. The filter component 19 can be a filter screen, filter cotton, HEPA filter, etc.

[0033] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
