Description

TECHNICAL FIELD

[0001] The present disclosure specifically relates to a hot-air hair straightener.BACKGROUND

[0002] As a type of household appliance for hairdressing, hair straighteners are widely used in people's daily lives. Conventional hair straighteners, also known as electric hair straighteners, are commonly referred to as straighteners. A heating body MCH or PTC or a heating element of the hair straightener is heated by a current and transfers heat to an aluminum plate or a ceramic plate. The hair straightener is used for clamping hair to change the physical properties of the hair, thereby straightening the hair. For example, a patent with Patent No. being CN202220920462.1 disclosed a hair straightener. However, these conventional hair straighteners have a general principle of heating by using a heating device. As a result, the conventional hair straighteners may easily cause hair to become dry due to excessive heat. A direct contact between the high-temperature straightener and the hair roughens the surface of the hair, such that the hair lacks moisture and becomes dry and yellow, the hair of a user is damaged, and the hair straightener is inconvenient to use.

[0003] The present disclosure is developed precisely based on the foregoing shortcomings.SUMMARY

[0004] An objective of the present disclosure is to overcome shortcomings in the prior art, so as to provide a hot-air hair straightener that can achieve a hair straightening effect and can also better protect hair.

[0005] The present disclosure is implemented by the following technical solutions:

[0006] A hot-air hair straightener includes a main body, where a main clamp and an auxiliary clamp capable of clamping with each other are disposed on the main body, the main clamp is provided with a first clamping block, the auxiliary clamp is provided with a second clamping block disposed corresponding to the first clamping block, the first clamping block and the second clamping block abut against each other to clamp hair when the main clamp and the auxiliary clamp are clamped with each other, the main clamp is provided with an air outlet located in front of the first clamping block, and a hot air generating device that is able to generate hot air and blow the hot air from the air outlet is disposed in the main body.

[0008] In the hot-air hair straightener described above, a negative ion generating device is disposed on the auxiliary clamp and is connected to a negative ion output tube, and an output end of the negative ion output tube passes through the auxiliary clamp and is then exposed from the inner side surface of the auxiliary clamp; and alternatively, a negative ion generating device is disposed on the main clamp and is connected to a negative ion output tube, and an output end of the negative ion output tube passes through the main clamp and is then exposed from the inner side surface of the auxiliary clamp.

[0009] In the hot-air hair straightener described above, a first air outlet lip is connected to a front side of the main clamp, a second air outlet lip is connected to a front side of the auxiliary clamp, and the first air outlet lip and the second air outlet lip together form an air guide port when the first clamping block and the second clamping block abut against each other.

[0010] In the hot-air hair straightener described above, the hot air generating device includes an air outlet housing and an air guide sleeve that have interconnected inner cavities, an air generating assembly that is able to generate airflow and convey the airflow into the air outlet housing is disposed in the air guide sleeve, a heating assembly that is able to heat air is disposed in the air outlet housing, the air outlet housing is provided with an air outlet window, the first clamping block is connected to the air outlet housing and covers the air outlet window, the first clamping block is provided with a hollow-out window, and the air outlet is formed between an edge of the hollow-out window and the air outlet housing.

[0011] In the hot-air hair straightener described above, the air guide sleeve has a guide segment that gradually narrows in a direction from an air inlet end to an air outlet end.

[0012] In the hot-air hair straightener described above, the guide segment gradually changes from a circular shape into a flat shape in the direction from the air inlet end to the air outlet end.

[0013] In the hot-air hair straightener described above, a tail end of the guide segment is sleeved on the air outlet housing, a plurality of snap-fit holes are provided in a side wall of the tail end of the guide segment, and snap-fit protrusions that are able to be inserted into the snap-fit holes are disposed on an outer side wall of the air outlet housing.

[0014] In the hot-air hair straightener described above, the entire air guide sleeve is of an integrated structure made of soft silicone or soft rubber.

[0015] Compared with the prior art, the present disclosure has the following advantages. 1. The hot-air hair straightener of the present disclosure includes the air outlet housing, the air guide sleeve, and the first clamping block. The first clamping block covers the air outlet of the air outlet housing. In this way, the air generating assembly generates airflow, and the airflow is heated by the heating assembly when passing through an air outlet cavity and finally blown from one side of the first clamping block. When the first clamping block is used to clamp hair, hot air is blown in a direction of the hair instead of being directly blown onto the hair, such that the hair can be uniformly heated over a wide range. In addition, the hair is smoothened and straightened by the hot air. Furthermore, the hot air is first blown to the first clamping block to cause the first clamping block to have a certain temperature. The hair is uniformly heated over a wide range by using the hot air as a main heating source. Then the first clamping block with the certain temperature is used to clamp the hair to further heat the hair, so as to prevent the hair from being subjected to concentrated heat in a small range for a short period of time to cause dry hair, thereby protecting the hair. 2. The hot-air hair straightener of the present disclosure is provided with the air guide gap and the air guide port during clamping, and the negative ion output tube is disposed at the air guide gap, such that the hot air blown by a product is rich in negative ions, which can reduce split ends of the hair of a user, thereby keeping the hair soft, smooth, and shiny.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present disclosure is further described below with reference to the drawings:

[0018] As shown in FIG. 1, the present disclosure develops a hair straightener. The hair straightener includes a main body A. The main body A is generally provided with two clamps, including a main clamp 1 and an auxiliary clamp 2. The main clamp 1 and the auxiliary clamp 2 are rotatably connected such that the main clamp and the auxiliary clamp can be clamped with each other, where the main clamp 1 and the auxiliary clamp 2 are not distinguished as primary and secondary and thus are interchangeable. Hair B is placed between the main clamp 1 and the auxiliary clamp 2. The hair is clamped by the main clamp 1 and the auxiliary clamp 2, and then is straightened through the pulling of an operator.

[0019] As shown in FIG. 2 to FIG. 4, this embodiment provides a hot-air hair straightener, including a main body A. The main clamp 1 and the auxiliary clamp 2 capable of clamping with each other are disposed on the main body A. The main clamp 1 is provided with a first clamping block 11. The auxiliary clamp 2 is provided with a second clamping block 21 disposed corresponding to the first clamping block 11. The first clamping block 11 and the second clamping block 21 abut against each other to clamp hair when the main clamp 1 and the auxiliary clamp 2 are clamped with each other. The main clamp 1 is provided with an air outlet 12 located in front of the first clamping block 11. A hot air generating device 13 that is able to generate hot air and blow the hot air from the air outlet 12 is disposed in the main body A. The hot air is generated by the hot air generating device 13, is finally blown from one side of the first clamping block 11, and is blown in a direction of the hair, such that the hair can be uniformly heated over a wide range and straightened by the hot air, thereby preventing the hair from becoming dehydrated and dry due to concentrated heat applied at a small range while achieving a hair straightening effect.

[0020] As a preferred implementation of this embodiment, FIG. 1 shows an inner side surface 100 of the main clamp 1, and FIG. 3 shows an inner side surface 200 of the auxiliary clamp 2. As shown in FIG. 4, the first clamping block 11 is disposed on the inner side surface 100 of the main clamp 1, and the second clamping block 21 is disposed on the inner side surface 200 of the auxiliary clamp 2. An air guide gap 3 for airflow to pass through is formed between the inner side surface 100 of the main clamp 1 and the inner side surface 200 of the auxiliary clamp 2 when the first clamping block 11 and the second clamping block 21 abut against each other. The air guide gap 3 is located in front of the air outlet 12, such that the hot air is blown outward along the air guide gap 3 after being blown from the air outlet 12.

[0021] As a more preferred implementation of this embodiment, as shown in FIG. 4 to FIG. 7, a negative ion generating device 14 is disposed on the auxiliary clamp 2 and is connected to a negative ion output tube 15, and an output end of the negative ion output tube 15 passes through the auxiliary clamp 2 and is then exposed from the inner side surface 200 of the auxiliary clamp 2; and alternatively, a negative ion generating device 14 is disposed on the main clamp 1 and is connected to a negative ion output tube 15, and an output end of the negative ion output tube 15 passes through the main clamp 1 and is then exposed from the inner side surface 200 of the auxiliary clamp 2. In this way, the hot air blown outward along the air guide gap 3 can convey negative ions generated by the negative ion output tube 15 outward. The negative ion generating device 14 may use a negative ion generator structure in the patent titled with a hair straightener with uniformly-dispersed negative ions and with Patent No. being CN202222636804.3. Split ends of the hair of a user can be reduced by increasing negative ion output on the auxiliary clamp 2, thereby keeping the hair soft, smooth, and shiny.

[0022] As a more preferred implementation of this embodiment, as shown in FIG. 3 and FIG. 4, a first air outlet lip 4 is connected to a front side of the main clamp 1, and a second air outlet lip 5 is connected to a front side of the auxiliary clamp 2. The first air outlet lip 4 and the second air outlet lip 5 together form an air guide port when the first clamping block 11 and the second clamping block 21 abut against each other. In this way, the hot air blown outward along the air guide gap 3 is finally blown outward from the air guide port 6.

[0023] Preferably, the first clamping block 11 and the second clamping block 21 both are of integrated structures made of metal or ceramic. Certainly, the first clamping block 11 and the second clamping block 21 may also use materials such as quartz and the like.

[0024] As a preferred implementation of this embodiment, as shown in FIG. 2 to FIG. 7, the hot air generating device 13 includes an air outlet housing 131 and an air guide sleeve 132 that have interconnected inner cavities. An air generating assembly 133 that is able to generate airflow and convey the airflow into the air outlet housing 131 is disposed in the air guide sleeve 132. A heating assembly 134 that is able to heat air is disposed in the air outlet housing 131. The air outlet housing 131 is provided with an air outlet window 135. The first clamping block 11 is connected to the air outlet housing 131 and covers the air outlet window 135. The first clamping block 11 is provided with a hollow-out window 110. The air outlet 12 is formed between an edge of the hollow-out window 110 and the air outlet housing 131. In particular, two ends of the air guide sleeve 132 respectively are an air inlet 1321 and an air outlet 1322. The air generating assembly 133 is disposed in the air guide sleeve 132 and can guide airflow from the air inlet 1321 to the air outlet 1322. The air outlet housing 131 defines an air outlet cavity 110. The air outlet housing 131 is provided with an air inlet 1311 communicating with an air guide sleeve air outlet 22. In this way, the airflow is first generated by the air generating assembly 133, is heated by the heating assembly 134 when passing through the air outlet cavity 110 and is finally blown from one side of the first clamping block 11. The first clamping block 11 covers the air outlet window 135, such that the hot air is vertically blown from the air outlet window 135, is then blocked by the first clamping block 11, and is then blown horizontally by turning 90°. The air generating assembly 133 may be referred to a fan assembly in a patent solution titled with a multi-functional hair curler and with Patent No. being CN202221694308.7. The heating assembly 134 may be a general resistance heating tube or resistance heating piece, or the like, or may be referred to a heating member in the patent solution titled with the multi-functional hair curler and with Patent No. being CN202221694308.7.

[0025] In particular, as shown in FIG. 5 and FIG. 6, the air outlet housing 131 is composed of a bottom cover 1313 and an upper cover 1314. A first heat-resistant partition plate 136 disposed corresponding to the heating assembly 134 is disposed on an inner side wall of the bottom cover 1313. A second heat-resistant partition plate 137 disposed corresponding to the heating assembly 134 is disposed on an inner side wall of the upper cover 1314. In this embodiment, the bottom cover 1313 and the upper cover 1314 are fixedly connected by means of providing threaded holes in the bottom cover and the upper cover and then penetrating screws into the threaded holes. Certainly, the bottom cover 1313 and the upper cover 1314 may also be fixedly connected in a snapping manner, an adhesive bonding manner, or the like. Furthermore, the first heat-resistant partition plate 136 and the second heat-resistant partition plate 137 may use metal or ceramic materials to prevent heat generated by the heating assembly 134 from being transferred to the bottom cover 1313 and the upper cover 1314, thus resulting in damage to a product.

[0026] As a preferred solution of this embodiment, as shown in FIG. 2 and FIG. 6, a temperature detection device 16 that can detect a temperature is further disposed in the air outlet housing 131. The temperature detection device 16 is a thermistor. Certainly, the temperature detection device 16 may also be other temperature sensors, and the like as long as the temperature of the hot airflow in the air outlet cavity 110 can be detected by the temperature detection device 16. Preferably, the temperature detection device 16 is disposed at an air outlet of the air outlet cavity 110, and an air temperature at the air outlet is detected by the temperature detection device 16 and fed back to a control module in the product to control operation of the heating assembly 134, so as to prevent the temperature of the generated hot air from being too high, thus resulting in damage to the hair.

[0027] In particular, as shown in FIG. 5 and FIG. 6, the air guide sleeve 132 has a guide segment 1323 that gradually narrows in a direction from the air inlet 1321 to the air outlet 1322, such that the airflow generated by the air generating assembly 133 is compressed when passing through the guide segment 1323, thereby increasing a flow rate of air outlet airflow. Preferably, the guide segment 1323 gradually changes from a circular shape into a flat shape in a direction from the air inlet end to the air outlet end, such that flat airflow is formed after the hot air is blown.

[0028] As a preferred solution of this embodiment, as shown in FIG. 5 and FIG. 6, a head end of the guide segment 1323 opens to form the air outlet 1322. The head end of the guide segment 1323 is sleeved on a tail end of the air outlet housing 131, and a front end of the guide segment 1323 is provided with a plurality of snap-fit holes 1323 around the air outlet 1322. The air outlet housing 131 is provided, around the air inlet 1311, with snap-fit protrusions 1312 that can be inserted into the snap-fit holes 1323. By inserting the snap-fit protrusions 1312 into the snap-fit holes 1323, the air guide sleeve 132 and the air outlet housing 131 are fixedly connected. Certainly, the air guide sleeve 132 in this example may also be made of a soft material, such that a front end of the air guide sleeve 132 is directly sleeved on the tail end of the air outlet housing 131.

[0029] In this embodiment, as a more preferred solution, the air guide sleeve 132 is of an integrated structure made of silicone. The entire air guide sleeve 132 is a soft sleeve made of the silicone, which allows the air guide sleeve, on the one hand, to be sleeved on the tail end of the air outlet housing 131, and on the other hand, to be better attached to an inner wall of a hair straightener housing, thereby improving mounting stability. Furthermore, most importantly, sleeving the soft air guide sleeve 132 around the air generating assembly 133 can block vibration transfer and reduce efficiency of noise transfer, thereby greatly reducing an impact of vibration and noise and improve usage comfort of the product.

[0030] As a variation of this embodiment, a heating device 22 that can heat the second clamping block 21 may be disposed on the auxiliary clamp 2. As shown in FIG. 4 and FIG. 7, preferably, the second clamping block 21 is of an integrated aluminum structure, and thus has a good heat-conducting property while having specific thermal insulation performance. The second clamping block 21 is internally provided with an accommodating cavity 210. The heating device 22 includes a heating element 221 disposed in the accommodating cavity 210, and the heating element 221 is a PTC heating body, an MCH ceramic heating body, or a heating film.

[0031] As a preferred implementation of this embodiment, as shown in FIG. 4 and FIG. 7, two side walls of the second clamping block 21 are provided with accommodating grooves 210 for the metal heating element 221 to pass through. The metal heating element 221 penetrates through the accommodating grooves 210 and is disposed around the second clamping block 21. The metal heating element 221 is connected to a circuit board or a power supply of the product via conducting wires. A specific connection manner is not shown in the figure, which is a conventional technique in the art, and thus is not described in detail here. Heat is generated through electric conduction of the foregoing metal heating element 221 and then transferred to the second clamping block 21, so as to heat the second clamping block 21.
