Description
Technical field
[0001] The present utility model relates to the field of hair care and styling devices, in particular to a styling curling iron with steam function. background
[0002] Curling combs are widely used in the hair care and styling industry to create curls. They primarily consist of heating elements, brush heads, circuit boards, and handles. The hair is curled by heating it to high temperatures; however, excessive heat can cause burns and damage the hair. Therefore, steam curling irons have been developed, which have steam generators in the comb to emit steam that moisturizes the hair and thus prevents damage. However, current steam-powered curling irons have several problems: for example, because they are not soundproofed or waterproof, they produce considerable noise and can splash hot water, posing a safety risk.Since the steam chamber only has a single chamber, refilling with cold water during use takes a very long time due to the long boiling time of the water, resulting in slow steam production. Subject of the utility model
[0003] This utility model addresses the shortcomings of existing technology by providing a simple structure, a rational design, faster steam generation after refilling with cold water, and a reduced noise level when using a curling brush with a steam function.
[0004] To solve the aforementioned technical problems, the present utility model employs the following technical solution: A curling brush with a steam function, comprising a handle, a brush head, a steam component, a water tank component, and a circuit board. The steam component includes a steam chamber and a heating element, the steam chamber being connected to the water tank component via a water pump. The water pump and the steam component are electrically connected to the circuit board. The brush head comprises an aluminum housing, a comb tooth holder, and comb teeth, the comb teeth being attached to the comb tooth holder and extending outwards through the aluminum housing. The heating element is mounted below the steam chamber, flush with its base. A waterproof seal is located inside the steam chamber, covering the steam space. A steam cover is fitted to the steam chamber, enclosing the waterproof seal.Both the steam lid and the waterproof seal are equipped with steam vents that connect to the steam chamber. A steam channel is located in the comb tooth holder, which also connects to the steam vents.
[0005] Furthermore, a partition wall is provided within the steam chamber, dividing the steam space into at least two chambers: at least one water inlet chamber and at least one steam production chamber. A connecting opening is provided in the partition wall, linking the steam production chamber to the water inlet chamber, which is connected to the water pump.
[0006] Furthermore, the partition wall is arranged longitudinally, with the steam openings on the steam cover and the waterproof seal also positioned longitudinally, and each steam opening being connected to a corresponding steam production chamber.
[0007] Preferably, two partitions are provided within the steam chamber, dividing the steam space into a water inlet chamber and two steam production chambers. The water inlet chamber is located between the two steam production chambers. A plurality of steam openings are provided on the steam cover and the watertight seal at positions corresponding to the two steam production chambers. The water pump is connected to one end of the water inlet chamber via a water line.
[0008] Furthermore, the heating device is attached via a mounting bracket which is mounted on the comb tooth holder, with the steam chamber being clamped between the two side edges of the mounting bracket.
[0009] Preferably, the waterproof seal is made of silicone rubber to form a waterproof silicone seal.
[0010] Furthermore, the water tank component and the circuit board are positioned in the grip area of the handle. The entire handle assembly is embedded in the handle and forms part of it, with the water pump located in front of the water tank component.
[0011] This utility model comprises a steam component within the brush head, equipped with steam vents on the comb teeth frame to allow steam to escape between the teeth. By first exposing the hair to steam, instances of hair smoke are reduced and hair damage is minimized. Simultaneously, the inclusion of a waterproof seal in the steam chamber not only reduces noise but also prevents hot water from being expelled with the steam, thus eliminating potential safety hazards. Furthermore, the steam chamber comprises at least two chambers, one of which is designated for the water supply. This design minimizes disturbances in other chambers during the cold water refill, allowing residual water in adjacent chambers to cool gradually. Consequently, steam performance remains largely unaffected. Description of the illustrations Fig. This is a three-dimensional perspective view of the present utility model.

[0012] In the illustration: 1 the handle, 2 brush head, 21 comb tooth holder, 22 comb teeth, 3 water tank component, 4 water pump, 5 designates the steam component, 51 steam chamber, 511 partition, 512 water inlet chamber, 513 steam production chamber, 514 connection opening, 52 steam lid, 53 waterproof seal, 54 heating unit, 55 mounting bracket, 56 steam opening, 6 circuit board, 7 water line. Specific embodiment
[0013] In this embodiment, the curling brush with steam function comprises, with reference to the Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig.5 a handle 1, a brush head 2, a steam component 5, a water tank component 3, and a circuit board 6. The steam component 5 comprises a steam chamber 51 and a heating element 54. The steam chamber 51 is connected to the water tank component 3 via a water pump 4. The water pump 4 and the steam component 5 are each electrically connected to the circuit board 6. The brush head (2) comprises an aluminum housing, a comb tooth holder (21), and comb teeth (22). The comb teeth (22) are attached to the comb tooth holder (21) and protrude through the aluminum housing. The comb teeth (22) can consist of bristle-like teeth or soft rubber teeth. The heating element 54 is mounted below the steam chamber 51, flush with its base. A waterproof seal 53 is positioned inside the steam chamber 51 and covers its steam space. A steam cover 52 is attached to the steam chamber 51 to enclose the waterproof seal 53.Both the steam lid 52 and the waterproof seal 53 have steam openings 56 that connect to the steam chamber. A steam channel is formed in the comb tooth holder 21, which is connected to the steam opening 56. The steam generated in the steam chamber 51 flows through the steam opening 56 and the steam channel and is then expelled to the outside through holes in the aluminum housing to moisten the hair.
[0014] Inside steam chamber 51, a partition 511 is installed, dividing the steam space into at least two chambers: at least one water inlet chamber 512 and at least one steam production chamber 513. A connecting opening 514 is provided in the partition 511, connecting the steam production chamber 513 to the water inlet chamber 512. The water inlet chamber 512 is connected to the water pump 4.
[0015] The partition wall 511 is arranged longitudinally, with the steam openings 56 on the steam cover 52 and the watertight seal 53 also arranged longitudinally. Each steam opening 56 is connected to the steam production chamber 513.
[0016] Within the steam chamber 51, two partitions 511 are installed, dividing the steam space into a water inlet chamber 512 and two steam production chambers 513. The water inlet chamber 512 is located between the two steam production chambers 513. The steam cover 52 and the watertight seal 53 have several steam openings 56, arranged according to the two steam production chambers 513, for example, five on each side, for a total of ten. The water pump 4 is connected to one end of the water inlet chamber 512 via a water line 7. During steam generation, the water level in the steam chamber 51 drops; cold water can be added via the water pump 4. The added cold water first enters the water inlet chamber 512 and then flows through the connecting openings 514 into the respective steam production chambers 513 on both sides.This prevents the entire steam chamber 51 from being immediately cooled down when the cold water flows in, which could impair steam generation. Instead, it ensures that the steam production chambers 513 can continue to produce steam before water enters them, thus reducing the duration of the interruption in steam generation.
[0017] The heating element 54 is attached via a fixed mounting bracket 55, which is mounted on the comb tooth holder 21. The fixed mounting bracket 55 clamps the steam chamber 51 between its two side edges, thus improving the compactness of the steam component 5. The heating element 54 uses a PTC device. Additionally, a temperature sensor can be positioned below the steam chamber 51. This sensor, which can use an NTC device, monitors the temperature of the steam chamber 51. This allows the circuit board 6 to regulate the water supply from the water pump 5 and ensure a constant water supply to the steam chamber 51.
[0018] The waterproof seal 53 is made of silicone rubber and forms a waterproof silicone seal that prevents water droplets from escaping along with the steam.
[0019] The water tank component 3 and the circuit board 6 are positioned at the grip point of the handle 1. The entire water tank component 3 is embedded in the handle 1 and forms part of the handle, with the water pump 4 located in front of the water tank component 3. This arrangement maximizes space utilization and allows the water tank component 4 to be designed as large as possible to increase the water storage capacity.
[0020] The present utility model has been described in detail above. The foregoing description represents only one preferred embodiment of the utility model. The scope of the utility model is not thereby limited; all equivalent changes and modifications made within the scope of this application remain within the scope of the utility model.
