Description

Technical Field

[0001] This invention relates to the field of household appliances, and more particularly to a spray hair straightener. Background Technology

[0002] Existing hair straighteners mainly consist of two plates, hinged together at their rear ends via a pivot. The front ends of each plate have interlocking heating plates with heating elements. During straightening, the heating elements heat the plates, which then clamp the hair together for the straightening process. This direct application of heat to the hair can easily damage it, and the resulting hair is prone to tangling. Therefore, spray straighteners have emerged on the market. These straighteners spray water vapor while straightening, providing both a straightening effect and hair conditioning. However, these spray straighteners have a drawback: the water is not sufficiently heated within the straightener, resulting in a mixture of liquid water droplets in the sprayed water vapor, severely affecting the straightening effect. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, this invention proposes a spray hair straightener that allows the water flow inside the straightener to be fully heated to form steam, which not only ensures the perming effect but also protects the hair.

[0004] This invention is achieved through the following technical solution: a spray hair straightener, comprising a first clamping plate and a second clamping plate, the tail ends of the first clamping plate and the second clamping plate being hinged together by a pivot. The front ends of the first clamping plate and the second clamping plate are respectively provided with a first heating component and a second heating component. The first heating component and the second heating component can follow the hinge rotation of the first clamping plate and move between a clamping position and a releasing position. The first heating component includes a first heat-conducting seat, within which are independently arranged a first heating chamber and a water storage chamber. The water storage chamber is arranged in a semi-enclosed manner around the first heating chamber. The first heating chamber contains a heating element. The first heating chamber includes a first end plate and a second end plate arranged opposite to each other. When the first... When the clamping plate and the second clamping plate are in the clamped position, the first end plate is in contact with the second heating component. The water storage cavity includes a third end plate and a fourth end plate. The water storage cavity contains a first absorbent foam and a second absorbent foam. The first absorbent foam is adjacent to the third end plate and located below the first heating cavity. The second absorbent foam is adjacent to the fourth end plate and located outside the first heating cavity. The fourth end plate is provided with several steam holes. The first absorbent foam is connected to the water tank on the first clamping plate through a water supply pipe. The water in the water tank is transported to the first absorbent foam. The water on the first absorbent foam absorbs the heat generated by the heating element to form wet steam, which flows along the water storage cavity to the second absorbent foam and forms steam at the second absorbent foam, which is then ejected from the steam holes.

[0005] Furthermore, the water storage cavity is L-shaped, the third end plate is vertically disposed below the first heating cavity, and the fourth end plate is horizontally disposed outside the first heating cavity.

[0006] Furthermore, a pressure plate is provided on the water storage cavity. The pressure plate extends along the length of the first heat-conducting seat. The pressure plate is provided with several water passage holes. The upper end of the pressure plate abuts against the second end plate, causing the second end plate to deform and thus causing the heating element to abut against the first end plate and the second end plate.

[0007] Furthermore, the first absorbent foam is disposed in the space formed between the pressure plate and the third end plate.

[0008] Furthermore, the second end plate extends downward from one end adjacent to the pressure plate to form an arc-shaped protrusion. This arc-shaped protrusion is located on the side of the pressure plate away from the third end plate. This arc-shaped protrusion can slow down the flow rate of wet steam passing through the water passage and flowing to the fourth end plate.

[0009] Furthermore, the diameter of the water passage is larger than the diameter of the steam passage.

[0010] Furthermore, the first end plate is located above the fourth end plate, so that the first end plate and the fourth end plate form a certain height difference in the vertical direction.

[0011] Furthermore, the first heat-conducting base is made of aluminum.

[0012] Furthermore, the first heat-conducting base is integrally formed.

[0013] Furthermore, the second clamping plate is provided with a linked slider and a button. The button is mounted on the second clamping plate, and the sliding of the slider can drive the button to move. The first clamping plate is provided with a water-pressing airbag. The air outlet of the water-pressing airbag is movably connected to the air inlet of the water tank through a conduit. The water outlet of the water tank is connected to the first absorbent foam through a water supply pipe. When the second clamping plate and the first clamping plate are in the clamping position, the slider slides to push the button closer to the first clamping plate and press the water-pressing airbag. The water-pressing airbag presses external air into the water tank and causes the water filled in the water tank to flow out through the water outlet of the water tank and be transported to the first absorbent foam through the water supply pipe.

[0014] Compared with existing technologies, the water storage cavity is arranged in a semi-enclosed manner around the first heating cavity, and a first absorbent foam and a second absorbent foam are set in the water storage cavity so that the water is heated into steam as much as possible in the water storage cavity, which can improve the atomization effect and thus ensure the perming effect.

[0028] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 12 This application provides a spray hair straightener, including a first clamp plate 1 and a second clamp plate 26. The tail ends of the first clamp plate 1 and the second clamp plate 26 are hinged by a pivot. The front ends of the first clamp plate 1 and the second clamp plate 26 are respectively provided with a first heating component 2 and a second heating component 27. The first heating component 2 and the second heating component 27 can follow the hinge rotation of the first clamp plate 1 and the second clamp plate 26 and move between a clamping position and a releasing position. Specifically, when the first clamp plate 1 and the second clamp plate 26 are in the clamping position, the first heating component 2 and the second heating component 27 cooperate to straighten the hair clamped between the first clamp plate 1 and the second clamp plate 26. When the first clamp plate 1 and the second clamp plate 26 are in the releasing position, the first clamp plate 1 and the second clamp plate 26 are far apart from each other, and the first heating component 2 does not contact the second heating component 27.

[0031] Please see Figures 1 to 9 The first heating component 2 includes a first heat-conducting base 3. The first heat-conducting base 3 has an independently set first heating chamber 4 and a water storage chamber 5. The water storage chamber 5 is arranged in a semi-enclosed form around the first heating chamber 4. The first heating chamber 4 contains a heating element. In this embodiment, the heating element is preferably a PTC heating element. The water storage chamber 5 receives the heat generated by the heating element and conducts it inside. The water storage chamber 5 is provided with a first absorbent foam 6 and a second absorbent foam 7. The second absorbent foam 7 is adjacent to the steam hole 8 on the first heat-conducting base 3. The first absorbent foam 6 is connected to the water tank 10 on the first clamping plate 1 through a water supply pipe 9, so that the water in the water tank 10 is transported to the first absorbent foam 6. The water on the first absorbent foam 6 absorbs the heat generated by the heating element 6 to form wet steam. The wet steam flows along the water storage chamber 5 and continues to absorb the heat generated by the heating element. After the wet steam flows to the second absorbent foam 7, it continues to absorb the heat generated by the heating element 6, and then forms steam. The steam is sprayed out from the steam hole 8 to protect the hair.

[0032] The water storage cavity 5 is arranged in a semi-enclosed form around the first heating cavity 4, and the first absorbent foam 6 and the second absorbent foam 7 are installed in the water storage cavity 5. The water flow can absorb the heat generated by the heating element as much as possible in the water storage cavity 5, so that the water flow can be heated in the water storage cavity 5 and turn into steam as much as possible, which can improve the atomization effect, thereby ensuring the perming effect and also conditioning the hair.

[0033] Specifically, the first heating chamber 4 includes a first end plate 12 and a second end plate 13 arranged opposite each other, and a first side plate 14 and a second side plate 15 connecting the two ends of the first end plate 12 and the second end plate 13. When the first clamping plate 1 and the second clamping plate 26 are in the clamping position, the first end plate 12 is in contact with the second heating component 27. The water storage chamber 5 is L-shaped and includes a third end plate 16 and a fourth end plate 17. The third end plate 16 is arranged almost vertically below the second end plate 13, and the fourth end plate 17 is arranged parallel to the first end plate 12. The fourth end plate 17 is provided with a plurality of steam holes 8, which are evenly distributed along the length of the first heat-conducting seat 3. The fourth end plate 17 is below the first end plate 12 so that the fourth end plate 17 and the first end plate 12 form a certain height difference in the vertical direction, that is, when the first clamping plate 1 and the second clamping plate 26 are in the clamping position... When positioned, the fourth end plate 17 is close to the second heating component 27, and a diffusion space 18 is formed between the fourth end plate 17 and the second heating component 27, so that the steam generated in the water storage chamber 5 can be ejected and diffused in the diffusion space 18 to moisten the hair and protect it. The vertical height of the diffusion space 18 is generally controlled within 0.7cm, preferably about 0.5cm. The fourth end plate 17 is connected to the first side plate 14, and part of the first side plate 14 and part of the second end plate 13 form a partition plate. The partition plate is configured to separate the first heating chamber 4 and the water storage chamber 5, so that the first heating chamber 4 and the water storage chamber 5 constitute two independently set chambers to achieve water and electricity separation. The first absorbent foam 6 is adjacent to the third end plate 16 and located directly below the first heating chamber 4, and the second absorbent foam 7 is adjacent to the fourth end plate 17 and located outside the first heating chamber 4. This configuration allows the water flow to absorb heat from the heating element 6 at the first absorbent foam 6 and the second absorbent foam 7. The first absorbent foam 6 and the second absorbent foam 7 are located at both ends of the water storage cavity 5, which can extend the heating path of the water flow as much as possible, improve the atomization effect of the water flow in the water storage cavity 5, reduce the liquid water droplet content in the sprayed steam, and thus ensure the perming effect.

[0034] To ensure full utilization of the heat from the heating element, a pressure plate 19 is provided on the water storage cavity 5. The pressure plate 19 extends along the length of the first heat-conducting seat 3 and has several water passage holes 20. The water passage holes 20 are evenly distributed along the length of the pressure plate 19. The pressure plate 20 is vertically positioned and its upper end abuts against the second end plate 13, causing the second end plate 13 to deform and thus abut against the heating element and the first end plate 12 and the second end plate 13. The second end plate 13 and the first end plate 12 can directly receive the heat conduction from the heating element. The first absorbent foam 6 is located in the space formed by the pressure plate 20, the second end plate 13 and the third end plate 16, and the first absorbent foam 6 can be tightly attached to the second end plate 13 and the third end plate 16. In this embodiment, the water storage cavity 5 includes a bottom plate 21, which is located below the second end plate 13. A third end plate 16 connects the second end plate 13 and the bottom plate 21. The bottom plate 21 is provided with a slot 22, which also extends along the length of the first heat-conducting seat 3. The second end plate 13 is provided with a recess 23, which is directly opposite the slot 22. The pressure plate 19 can be directly inserted between the recess 23 and the slot 22 in a manner perpendicular to the water storage cavity 5, so that the pressure plate 19 can be detachably assembled between the recess 23 and the slot 22. The pressure plate 19 causes the bottom plate 21 and the second end plate 13 to deform.

[0035] The second end plate 13 extends downward from one end adjacent to the pressure plate 19 to form an arc-shaped protrusion 24. The arc-shaped protrusion 24 is located on the side of the pressure plate 19 away from the third end plate 16, which reduces the gap between the arc-shaped protrusion 24 and the bottom plate 19. The arc-shaped protrusion 24 can slow down the flow rate of wet steam passing through the water passage 20 and flowing to the fourth end plate 17. This arrangement can also prolong the atomization time of the water flow in the water storage chamber 5, thereby improving the atomization effect of the water flow in the water storage chamber 5. In this embodiment, the diameter of the water passage 20 is larger than the diameter of the steam hole 8 to further improve the atomization effect of the water flow in the water storage chamber 5.

[0036] In this embodiment, the thickness D1 of the first absorbent foam 6 is greater than the thickness D2 of the second absorbent foam 7, the width W1 of the first absorbent foam 6 is greater than the width W2 of the second absorbent foam 7, and the length L1 of the first absorbent foam 6 is equal to the length L2 of the second absorbent foam 7. This arrangement allows the first absorbent foam 6 to absorb more water and to be heated as much as possible to form a small amount of wet steam with liquid water droplets. The wet steam only needs to receive a certain amount of heat at the second absorbent foam 7 to improve the atomization effect, and it is almost free of liquid water droplets when it is sprayed out from the steam hole 8. The inventors conducted multiple experiments within the water storage chamber 5, using either the first absorbent foam 6 or the second absorbent foam 7 alone. However, the atomization effect was not ideal, with liquid droplets spraying out and affecting the perming effect. The inventors also conducted experiments adjusting the volume of the first absorbent foam 6 and the second absorbent foam 7. The thickness D2 of the second absorbent foam 7 was between one-half and two-thirds of the thickness D1 of the first absorbent foam 6, and the width W2 of the second absorbent foam 7 was approximately half the width W1 of the first absorbent foam 6. The atomization effect and steam output were optimal when the length L1 of the first absorbent foam 6 and the length L2 of the second absorbent foam 7 were equal.

[0037] The first heat-conducting base 3 is preferably made of aluminum, so that the heat generated by the heating element can be effectively transferred on the first heat-conducting base 3, thereby providing heat to the entire water storage chamber 5. That is, the third end plate 16, the fourth end plate 17, and the partition plate, etc., can all receive the heat generated by the heating element and be heated, thereby providing heat to the entire water storage chamber 5, the first absorbent foam 6, and the second absorbent foam 7, so as to improve the atomization effect of the spray hair straightener.

[0038] In this embodiment, the first heat-conducting base 3 is integrally formed. It should be noted that sealing caps 25 are provided at both ends of the first heat-conducting base 3 along its length. The sealing caps 25 are preferably made of plastic to ensure that the water inside the first heat-conducting base 3 does not leak out and to prevent leakage of electricity.

[0039] Please see Figure 1 , 9 Up to 12, the second heating assembly 27 includes a second heat-conducting seat 28, which has a second heating chamber and also houses a heating element. The second heat-conducting seat 28 is preferably made of aluminum. The second heat-conducting seat 28 cooperates with the first heat-conducting seat 3 to achieve hair perming. Sealing caps 25 are also provided at both ends of the second heat-conducting seat 28. When the first clamping plate 1 and the second clamping plate 26 are in the clamping position, the aforementioned diffusion space 18 is formed between the fourth end plate 17 and the second heat-conducting seat 28.

[0040] The second clamping plate 26 is equipped with a slider 29 and a button 30 that are linked together. The button 30 is vertically inserted into the second clamping plate 26. The slider 29 can slide to drive the button 30 to move in a direction perpendicular to the second clamping plate 26. The first clamping plate 1 is equipped with a water-pressing airbag 31. The air outlet of the water-pressing airbag 31 is connected to the air inlet of the water tank 10 through a conduit. The water outlet of the water tank 10 is connected to the first absorbent foam 6 through a water supply pipe 9. When the second clamping plate 26 and the first clamping plate 1 are in the clamping position, the slider 29 slides to push the button 30 close to the first clamping plate 1 and press the water-pressing airbag 31. The water-pressing airbag 31 presses the outside air into the water tank 10 and causes the water filled in the water tank 10 to flow out through the water outlet of the water tank 10 and be transported to the first absorbent foam 6 through the water supply pipe 9.

[0041] The water tank 10 can be fixedly mounted on the first clamping plate 1 or detachably mounted on the first clamping plate 1. In this embodiment, the water tank 10 is detachably mounted on the first clamping plate 1, and a detachable cover plate 11 is provided at the corresponding position of the water tank 10 to fix the water tank 10. The detachable mounting method of the water tank 10 and the cover plate 11, the sliding method of the slider 29 to drive the movement of the button 30, and the method of the water pressure airbag 31 to push the water in the water tank 10 to the first water-absorbing foam 6 are all the same as the prior art and will not be described in detail here.

[0042] In use, when the first clamping plate 1 and the second clamping plate 26 are in the clamping position, the slider 29 is pushed to push the water in the water tank 10 onto the first absorbent foam 6. After the first absorbent foam 6 absorbs a certain amount of water at once, it forms wet steam under the action of the heating element. The wet steam passes through the water hole 20 and flows along the water storage cavity 5 to the second absorbent foam 7. After steam is formed at the second absorbent foam 7, it is sprayed out from the steam hole 8 and diffuses in the diffusion space 18 to protect the hair. Since the steam in the diffusion space 18 contains no or very little liquid water droplets, the perming effect can be guaranteed and will not affect the perming effect.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0044] This invention has been illustrated through several specific embodiments. Those skilled in the art will understand that various modifications and equivalent substitutions can be made to this invention without departing from its scope. Furthermore, various modifications can be made to this invention for specific situations or circumstances without departing from its scope. Therefore, this invention is not limited to the specific embodiments disclosed, but should include all embodiments falling within the scope of the claims.
