Description

[0001] The present invention relates to the technical field of steam generators, and in particular to a steam generating device and steam equipment. Background Art

[0002] 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.

[0003] In the prior art, one method of steam straightening is to directly heat the water in the 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.

[0031] Embodiment 1

[0032] like Figures 1 to 3 As shown, a steam generating device has a good heating effect, can fully vaporize water, avoid water leakage or splashing during use, and affect the user experience, and has a simple structure and is easy to produce. It can be used in steam equipment such as steam curling irons, hair straightening irons or steam irons. The steam generating device of this embodiment includes a heating bracket 1 provided with a heating plane and a heating plate 2 provided on the heating bracket 1, wherein the heating plate 2 can be but is not limited to an MCH heating element, a PTC heating element or a heating wire. The heating plate 2 in this embodiment is a PTC heating element, which has high heating efficiency, mature technology, low cost, and good heating effect.

[0033] The heating bracket 1 of this embodiment is provided with a heating installation groove 11 arranged along its own length direction on the end face of one side away from the heating plane, and the surface of the heating installation groove 11 is provided with a heating water channel arranged closely thereto. The heating plate 2 is inserted into the heating installation groove 11 to heat the heating installation groove 11, so that the heating water channel arranged on the surface of the heating installation groove 11 can achieve contact heating, thereby heating and vaporizing the water flowing inside to form water vapor. The length of the heating plate 2 of this embodiment is adapted to the heating installation groove 11, so that when the heating plate 2 is working, each position of the heating installation groove 11 can achieve uniform heating, thereby effectively improving the heating efficiency of water, thereby improving the steam output effect. In addition, the steam channels 3 arranged parallel to the heating installation groove 11 are symmetrically arranged on both sides of the heating installation groove 11 of this embodiment, and the end of the heating water channel is connected to the steam channel 3, so that the water vapor entering the steam channel 3 after being heated in the heating water channel can still be heated by the heating installation groove 11, thereby maintaining the vaporized state of water and then outputting it to the heating plane. Through the above arrangement, the present embodiment allows the entire steam transmission process to be heated after water enters the heating water path, thereby effectively improving the steam output effect of the present embodiment and avoiding the occurrence of water leakage.

[0034] Specifically, Figure 1 and Figure 2 As shown, the heating bracket 1 of this embodiment is provided with a heating boss 5 arranged along the length direction of the heating bracket 1 on the side away from the heating plane, wherein the heating installation groove 11 and the steam channel 3 are both arranged on the heating boss 5. The heating installation groove 11 is formed by arranging the heating boss 5 to install the heating plate 2, and the steam channel 3 is formed on both sides of the heating groove arranged on the heating boss 5. This can not only achieve sufficient heating of water and ensure the steam output effect, but also simplify the structure of the heating bracket 1 and reduce the overall weight, reduce the production cost and facilitate production.

[0035] Among them, in order to adapt to the structure of the above-mentioned heating bracket 1, the heating water path of this embodiment is two heating pipes 6 closely attached to the surface of the heating boss 5. After the heating plate 2 is inserted into the heating mounting groove 11, the entire heating boss 5 can be evenly heated under the action of the heating plate 2, so that the heating pipe 6 closely attached to the surface of the heating boss 5 can be heated and the water inside can be vaporized. At the same time, the two integral channels also arranged on the heating boss 5 can also be heated synchronously, thereby maintaining the continuous heating of the internal steam to avoid the formation of condensed water.

[0036] One end of the two heating pipes 6 of this embodiment is commonly connected to a Y-shaped joint 9 connected to the equipment water tank, and the other end of the heating pipe 6 extends along the length direction of the heating boss 5 and is connected to the steam channel 3, so that the two heating pipes 6 can simultaneously input water for heating, so that the steam in the two steam channels 3 is kept consistent and output at the same time, so as to achieve a good working effect. In addition, a continuous bending section 61 is also provided in the middle of the heating pipe 6 of this embodiment, so that the water input into the heating pipe 6 can extend the contact time with the heating boss 5 through the continuous bending section 61, thereby extending the heating to facilitate the full gasification of the water, thereby making the temperature of the water vapor entering the steam channel 3 higher, which can effectively reduce the generation of condensed water, thereby achieving good working performance.

[0037] like Figure 2 and Figure 4 As shown, the steam channel 3 of this embodiment is equidistantly provided with steam holes 31 penetrating to the heating plane, and the water vapor in the steam channel 3 can be output to the surface of the heating plane through each steam hole 31, so that the arrangement of the water vapor on the surface of the heating plane is more uniform, which is convenient for improving the working ability and effect of the product, thereby improving the user experience. The heating plane of this embodiment is provided with a steam retention groove 12 arranged along the arrangement direction of the steam holes 31 and penetrating and connecting each steam hole 31. The steam output through the steam holes 31 can be temporarily stored in the steam retention groove 12, thereby avoiding the steam hole 31 being blocked and affecting the steam output due to the product being close to the working surface during use. At the same time, a number of connecting grooves 13 are connected between the two steam retention grooves 12 of this embodiment, so that the steam output from the steam hole 31 can also be moved to other positions of the heating plane through the connecting grooves 13, so that the working plane can be covered with steam during the user's use, thereby improving the working effect.

[0038] like Figure 2 and Figure 3 As shown, the steam channel 3 of this embodiment gradually tilts downward from one end where the steam enters to the other end to form an inclined surface, and a water outlet 4 is provided at the lowest end of the inclined surface, so that after the steam in the steam channel 3 forms condensed water due to insufficient heating, the condensed water can flow along the inclined surface, so that it is continuously heated by the heating body during the flow process, and finally can be output through the steam hole 31 after vaporization. If it still cannot be vaporized in the end, it can also flow to the water outlet 4 and leave the steam channel 3, thereby effectively avoiding the occurrence of water leakage from the steam hole 31. In addition, the water outlet 4 of this embodiment is connected to the external space or the heating water circuit, so that the water flowing out through the water outlet 4 can flow directly out to the external space, or flow back to the heating water circuit for reheating, which can reduce water waste.

[0039] Specifically, the end of the heating pipe 6 of this embodiment is connected to the center of the steam pipe, so that the steam entering the steam pipe can diffuse from the center to both ends, thereby making the steam output of each steam hole 31 more uniform, which can improve the working effect of this embodiment. In addition, the steam enters from the middle of the steam pipe, so that the bottom surface of the steam pipe of this embodiment gradually tilts downward from the position where the steam enters toward the two ends, thereby allowing the condensed water that is not completely vaporized to flow from both sides, which can improve the ability to remove the condensed water.

[0040] In order to further avoid the occurrence of water leakage, the steam channel 3 of this embodiment is also provided with a baffle 32 protruding around the outer periphery of each steam hole 31, so that when the condensed water flows on the inclined surface, it can be blocked by the baffle 32 to avoid entering the steam hole 31 and causing water leakage; and, the bottom of the baffle 32 of this embodiment is provided with a water guide groove 33, and each water guide groove 33 is connected in sequence, and the water guide groove 33 at the end of the inclined surface is connected with the water outlet 4, and the condensed water on the inclined surface can flow through the water guide groove 33, which can avoid the water level being too high and causing the condensed water to submerge the baffle 32 and cause water leakage, while also ensuring the accurate flow of water.

[0041] Embodiment 2

[0042] like Figures 5 and 6 As shown, the difference from the first embodiment is that the heating bracket 1 of the second embodiment is a flat plate, and the heating installation groove 11 is arranged in the middle of the heating bracket 1 and runs from one side of the heating bracket 1 to the other side of the heating bracket 1, so that the heating plate 2 can be directly plugged into the heating installation from one side of the heating bracket 1, and the entire heating bracket 1 can be evenly heated. The heating water path of this embodiment is a channel group symmetrically arranged on both sides of the heating installation groove 11, wherein the channel group includes two heating channels 7 extending along the length direction of the heating bracket 1 and symmetrically arranged on both sides of the steam channel 3. For ease of understanding, this embodiment will make the heating channel 7 close to the heating installation groove 11 the first channel, and the heating channel 7 away from the heating installation groove 11 as the second channel. One end of the two first channels of this embodiment is connected with a Y-type connector 9, so that the water in the equipment water tank can be simultaneously input into the two first channels through the Y-type connector 9, thereby facilitating the simultaneous output of the two steam channels 3 to obtain a better working effect.

[0043] In this embodiment, the first channel and the second channel are connected in sequence, wherein the other end of the first channel is connected to the second channel via a U-shaped tube, and at the same time, the other end of the second channel connected to the first channel is connected to the steam channel 3 via a U-shaped tube, so that the water input into the first channel can flow through the length of two heating installation grooves 11 before being output to the steam channel 3, thereby extending the heating time of the water, thereby ensuring the vaporization effect of the water, and avoiding water from entering the condensation channel without being fully vaporized, causing the steam hole 31 to leak.

[0044] Embodiment 3

[0045] like Figures 7 and 8 As shown, the heating support 1 of the third embodiment is a flat plate with grooves on the surface, wherein the heating water channel is a heating channel 8 laid on the surface of the heating support 1 on the side away from the heating plane. The heating channel 8 of this embodiment is provided with two and the two heating channels 8 are symmetrically arranged on both sides of the heating installation groove 11, thereby ensuring the simultaneous output of the two steam channels 3; and the two heating channels 8 of the heating channel 8 of this embodiment are both extended along the length direction of the heating support 1 and surrounded by the outer side of the steam channel 3. The spiral circuit arrangement can effectively extend the flow time when the water flows along the heating channel 8, and then it can be fully heated, which is convenient for achieving the full gasification of water and avoiding water leakage. A connecting channel is connected between the two heating channels 8 of this embodiment, and one end of one of the heating channels 8 is provided with a connecting port connected to the equipment water tank, so that the water in the equipment water tank can enter one of the heating channels 8 through the connecting port, and enter the other heating channel 8 through the connecting channel, so that the present embodiment can achieve the simultaneous output of the steam channels 3 on both sides without setting a Y-type interface, which simplifies the overall structure of the present embodiment and is convenient for production.

[0046] The heating support 1 of this embodiment is provided with a top cover plate 10 covering the heating channel 8 on the side facing away from the heating plane, so that the heating channel 8 and the steam channel laid on the heating support 1 can be sealed through the top cover plate 10, so that the heating channel 8 and the steam channel can form a sealed pipeline, thereby ensuring efficient gasification of water and avoiding water leakage; at the same time, it is also convenient for production.

[0047] Embodiment 4

[0048] This embodiment provides a steam device, including the steam generating device in any one of Embodiments 1 to 3. The steam device may be, but is not limited to, a steam curling iron, a steam straightening iron, a steam iron, etc. A connecting portion is provided on the steam generating device of this embodiment, so that the steam device can be installed with the steam generating device through the connecting portion.

[0049] In summary, the working principle of the present application is as follows: the present application sets a heating installation groove 11 on the side of the heating bracket 1 away from the heating plane, and sets the heating water path close to the surface of the heating installation groove 11, so that after the heating plate 2 is plugged into the heating installation groove 11, the entire heating installation groove 11 can be heated, and then the heating water path attached to the surface of the heating installation groove 11 can be fully heated so that the internal is fully heated and vaporized, and the heating effect is good, which can effectively improve the efficiency of converting water into steam and avoid water leakage. At the same time, the structure is simple and the manufacturing cost is low, and it is suitable for a variety of steam heating products. In addition, the present application sets the steam channel 3 to an inclined surface that gradually tilts downward, and sets a fence 32 at each steam hole 31, so that the water that has not been completely vaporized into water vapor entering the steam channel 3 can be blocked by the fence 32 and flow along the inclined surface to the outside or return to the heating water path for reheating, thereby avoiding the occurrence of water leakage in the steam hole 31 during use, which can effectively improve the user experience, and the structure is simple and easy to produce.
