Technical Field
[0001] The utility model relates to the technical field of hair straighteners, in particular to a steam generating device for hair straighteners. Background Art
[0002] In recent years, with the change of aesthetics, more and more people like to keep straight hair. Naturally vertical hair or hair that has undergone multiple curling and hairdressing usually appears dry and messy, so it needs to be combed with the help of some hair straighteners.
[0003] At present, hair straighteners on the market are generally divided into two categories: direct heat type and steam type. General direct heat type hair straighteners use electric current to heat the heating element MCH, PTC or heating wire of the hair straightener, and then transfer the heat to the aluminum plate or ceramic plate to heat and comb the hair. However, direct heat type has high requirements on materials, lacks safety, and is easy to damage hair. Steam type heats and combs hair by heating fluids such as water, which is closer to natural processing, less damage to hair quality, and has low material requirements, but still has good safety performance.
[0004] In the prior art, one method of steam straightening is to directly heat the water in the integrally formed water tank and directly pass the steam through the steam hole to straighten the hair. This method easily causes the heated water to leak or splash. Another method is to separate the heated water and the generated steam through an extremely complex sealing structure to reduce the problems of the aforementioned method. However, the complex structure of this method leads to high cost of the hair straightener, which is not suitable for popularization and faces great market competition pressure. Utility Model Content

Unless otherwise specified, "plurality" means two or more.
[0034] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.
[0035] like Figure 1 to Figure 2 As shown, the utility model relates to a steam generating device 1 , comprising: a first shell 11 , a sealing plate 12 , a heater bracket 13 , a second shell 15 and a heater 14 .
[0036] like Figure 3 As shown, in some examples, the first housing 11 is formed with a plurality of grooves. In some examples, the grooves form a plurality of interconnected chambers through a plurality of protrusions. In this case, the violent movement of the fluid due to heating can be effectively blocked by the plurality of protrusions.
[0037] In some examples, some of the protrusions are used as barriers to form a large volume chamber. In other examples, some of the protrusions are used as guides to form a small volume fluid channel. For example, Figure 3 As shown, chamber 112a, chamber 112b, chamber 112c and chamber 112d are large-volume chambers formed by protrusions 113a and 113b, chamber 112e and chamber 112f are small-volume chambers formed by protrusions, and the others may be fluid channels formed by protrusion 113d or protrusion 113e.
[0038] In some examples, the sealing plate 12 is adhered to the surface of the first housing 11 where the groove is formed, such as Figure 4 As shown, the sealing plate 12 has a first through hole 121. In some examples, the sealing plate 12 is made of silicone.
[0039] In some examples, the heater bracket 13 may be bonded to the sealing plate 12. Figure 5 As shown, in some examples, the heater bracket 13 has a second through hole 131. In this case, the heater 14 and the heated water are isolated by the heater bracket 13 and sealed by the sealing plate 12, which can improve the safety of the hair straightener 2 and effectively prevent the heated water from leaking.
[0040] In some examples, the first through hole 121 may be a waist-shaped hole. In some examples, the second through hole 131 may be a waist-shaped hole.
[0041] like Figure 1 As shown, in some examples, the heater 14 has a heating function and is disposed between the second housing 15 and the heater support 13 .
[0042] like Figure 6 As shown, in some examples, the heater 14 can be in the shape of a long strip. In some examples, the heater 14 can be connected to the control system of the hair straightener 2 through a wire 141.
[0043] In some examples, the heater 14 is a PTC heater. The PTC heater has low thermal resistance and high heat exchange efficiency. In this case, if the fan fails and stops, the PTC heater will not be able to dissipate enough heat, and its power will automatically drop sharply. At this time, its surface temperature is maintained at around the Curie temperature, and the surface "reddening" phenomenon of the electric heating tube heater 14 will not occur. The function of automatic constant temperature can be achieved, and the safety of the hair straightener 2 is effectively improved.
[0044] like Figure 7 As shown, in some examples, the second housing 15 has a plurality of fitting parts 152 penetrating the first through hole 121 and the second through hole 131 and fitting into the groove, and the fitting parts 152 are formed with a plurality of steam holes 151. Specifically, the fitting parts 152 can be fitted into the chambers 112e and 112f.
[0045] In some examples, the groove forms a plurality of interconnected chambers through a plurality of protrusions, and at least one chamber is connected to a plurality of steam holes 151. In this case, the fitting portion 152 of the second housing 15 is fitted into at least one chamber and has a steam hole 151. In this case, the steam can be discharged through the fitting gap and the steam hole 151, and the heated water is blocked, so there is no problem of splashing.
[0046] like Figure 4 As shown, in some examples, the sealing plate 12 matches the shape of the first housing 11 and has a hollow area 122 that matches the chamber. In this case, the volume of the chamber can be increased, thereby storing more water and increasing the use time of the hair straightener 2.
[0047] In some examples, the hollow area 122 may match the area where the cavity of the first shell 11 is located, that is, the shape and size of the hollow area 122 may be consistent with the cavity.
[0048] In some examples, the shapes and sizes of the first through hole 121 and the second through hole 131 match the fitting portion 152 .
[0049] like Figure 3 As shown, in some examples, the first shell 11 further has a water inlet 111 , and the water inlet 111 is disposed on a side surface perpendicular to the surface of the first shell 11 where the groove is formed.
[0050] In some examples, the second housing 15 may be formed with a groove, and the shape may match the heater 14. In this case, it is convenient to install and fix the heater 14, thereby reducing the space occupied by the hair straightener 2.
[0051] like Figure 7 or Figure 8 As shown, in some examples, a plurality of columnar comb teeth 153 are formed on the surface of the second shell 15 , and the outlet 1511 of the steam hole 151 is located at the comb teeth 153 or in the area where the comb teeth 153 are located.
[0052] like Fig.10 or Fig.11 As shown, in some examples, a hair straightener 2 includes two steam generating devices 1, the two steam generating devices 1 are connected by a hinge structure, and the comb teeth 153 in the two steam generating devices 1 are staggered. In this case, the hair straightener 2 can be gathered together when not in use, and the comb teeth 153 are staggered, thereby reducing space occupation and improving convenience.
[0053] like Fig. 9 or Fig.11As shown, in other examples, the comb teeth 153 on the surface of the second shell 15 may be optional. For example, the surface of the second shell 15 may be a flat surface or a slightly raised block. In some examples, the outlet 1511 of the steam hole 151 may be located on the flat surface or the slightly raised block and the area where it is located.
[0054] In summary, the beneficial effects of the utility model are:
[0055] 1. The heater 14 and the heated water are isolated by the heater bracket 13 and sealed by the sealing plate 12, which can improve the safety of the hair straightener 2 and effectively prevent the heated water from leaking.
[0056] 2. The interconnected chambers formed by the first shell 11 can effectively block the violent movement of the fluid due to heating, and the fitting portion 152 of the second shell 15 is fitted into at least one chamber and has a steam hole 151. In this case, the steam can be discharged through the fitting gap and the steam hole 151, and the heated water will not splash due to the blocking.
[0057] 3. The PTC heater has a small thermal resistance and high heat exchange efficiency. When the fan fails and stops, the PTC heater cannot dissipate enough heat, and its power will automatically drop sharply. At this time, its surface temperature is maintained at around the Curie temperature, and the surface "reddening" phenomenon like the electric heating tube heater 14 will not occur. The function of automatic constant temperature can be achieved, effectively improving the safety of the hair straightener 2.
[0058] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the protection scope of the present utility model.
