Description

Technical Field

[0001] This utility model relates to the technical field of hair styling tools, and in particular to a steam generating device. Background Technology

[0002] In the field of hair styling tools, the performance of the steam generator in a perm comb, which combines perming and conditioning functions, directly affects the styling results and user experience. Steam softens the hair cuticle, helping perming agents penetrate better while reducing high-temperature damage to the hair. Therefore, an efficient and stable steam generator is a core component of a perm comb. Existing perm comb steam generators typically employ a continuously curved pipe structure to ensure sufficient heating of the water flow and generation of adequate steam. The initial intention of this design was to increase the contact area between the water flow and the heating element by increasing the pipe length and the number of bends, thereby improving heat exchange efficiency and ensuring that the water flow is fully heated to a vaporized state. For example, Chinese patent document CN119289340A discloses a steam generator and steam equipment, in which a continuous bend section is provided in the middle of the heating pipe. This allows the water entering the heating pipe to have a longer contact time with the heating boss through the continuous bend section, thereby extending the heating process and facilitating the full vaporization of the water. This results in a higher temperature of the water vapor entering the steam channel, effectively reducing the generation of condensate and thus achieving good working performance.

[0003] However, existing steam generators have the following shortcomings in practical use: First, the continuous bending of the pipes requires specialized high-precision pipe bending equipment, which has high purchase and maintenance costs, increasing the overall investment cost. Second, the complex structure of continuously bent pipes can easily lead to increased assembly difficulty and reduced production efficiency during subsequent assembly and welding processes due to structural interference, indirectly increasing production costs. Therefore, the steam generator described in this application is proposed. Utility Model Content

[0032] like Figures 1 to 6 As shown, in one embodiment, a steam generating device 1 includes a base plate 10 and a steam assembly. The steam assembly includes a first end block 20, a second end block 21, a through pipe 22, and a plurality of conduits 23. The first end block 20 and the second end block 21 are respectively disposed on opposite ends of the base plate 10. The first end block 20 is provided with a plurality of first guide grooves 200, each of which is connected to a groove 100. The second end block 21 is provided with a second guide groove 210. One end of each conduit 23 is connected to each of the first guide grooves 200, and the other end of each conduit 23 is connected to both ends of the second guide groove 210. The groove 100, the first guide grooves 200, and the conduits 23 together form an S-shaped channel. One end of the through pipe 22 is connected to the second guide groove 210, and the other end of the through pipe 22 passes through the first end block 20 and extends from the end of the first end block 20 away from the second end block 21. The through pipe 22 is used to connect to a water source.

[0033] It should be noted that two protrusions are provided on the base plate 10, and the two protrusions are arranged facing each other on one side surface of the base plate 10. Two grooves 100 are formed, and the two grooves 100 extend from one side surface of the base plate 10 into the protrusions, so that the two grooves 100 are embedded in the base plate 10, and the grooves 100 have a strip-shaped structure. Further, the first end block 20 and the second end block 21 are respectively provided at opposite ends of the base plate 10, and the opening of the second guide groove 210 is located on the side of the second end block 21 near the first end block 20, and each first guide groove 200 is located on the side of the first end block 20 near the second end block 21. Further, one end of each first guide groove 200 is connected to one end of each groove 100, one end of each conduit 23 is connected to the end of each first guide groove 200 away from the groove 100, and the end of each conduit 23 away from the first guide groove 200 is connected to both ends of the second guide groove 210. Furthermore, the groove 100, the first guide channel 200, and the conduit 23 together form an S-shaped channel, and the ends of the two S-shaped channels away from the groove 100 are respectively connected to the two ends of the second guide channel 210. Furthermore, one end of the connecting pipe 22 is connected to the middle position of the second guide channel 210, so that both S-shaped channels are connected to the connecting pipe 22 through the second guide channel 210, and the other end of the connecting pipe 22 passes through the first end block 20 and is connected to the water source. Furthermore, two conduits 23 are provided, with the two conduits 23 located on both sides of the connecting pipe 22, and the groove 100 is a long, narrow groove structure, with the two grooves 100 located on the sides of the two conduits 23 away from the connecting pipe 22, thus making each groove 100, each conduit 23, and the connecting pipe 22 arranged in parallel and equidistant. One end of the through pipe 22 is connected to the second guide channel 210, and the two ends of the two conduits 23 are respectively connected to the ends of the first guide channels 200 and the second guide channels 210. Furthermore, the two first guide channels 200 are respectively connected to the two recesses 100, forming a continuously curved S-shaped pipe with the through pipe 22 as the center and on both sides. This allows water to flow through the through pipe 22, past the first end block 20, towards the second end block 21 into the second guide channel 210. The water is divided into two streams by the second guide channel 210, which then flow through the two conduits 23 towards the first end block 20 into the first guide channels 200. Each first guide channel 200 guides the water towards the second end block 21 into the respective recesses 100. This increases the length and number of bends of the pipe, thereby improving heating efficiency.

[0034] It should be noted that the through pipe 22 and each conduit 23 are all straight pipe structures, and the length of the through pipe 22 is greater than the length of the conduit 23. One end of the through pipe 22 is connected to the second guide channel 210, and the other end of the through pipe 22 is fixed by adhesive with waterproof and high-temperature resistant adhesive, such as silicone sealant. This ensures that the through pipe 22 remains connected to the second guide channel 210 and seals the connection between the through pipe 22 and the second guide channel 210, preventing water from seeping out from the gap between the second guide channel 210 and the through pipe 22. Furthermore, since the through pipe 22 and each conduit 23 are all straight pipe structures, their processing is simple, thereby reducing equipment investment costs and assembly difficulty, and thus improving production efficiency.

[0035] like Figure 2 , Figure 4 , Figure 6 As shown, in one embodiment, the second guide channel 210 includes a straight section 2100 and a U-shaped section 2101. The straight section 2100 is connected to the U-shaped section 2101, the through pipe 22 is connected to the straight section 2100, and each guide pipe 23 is connected to both ends of the U-shaped section 2101.

[0036] It should be noted that the second guide channel 210 tends to have an E-shaped structure, and the second guide channel 210 is connected to the upper surface and end face of the second end block 21 near the first end block 20 and the top plate, so that the through pipe 22 and each conduit 23 can be embedded in the second end block 21 and communicate with the second guide channel 210. When the second end block 21 is set on the bottom plate 10, the bottom surface of the bottom plate 10 and the upper surface of the second end block 21 surround the second guide channel 210. Further, the second guide channel 210 includes a straight part 2100 and a U-shaped part 2101, and the straight part 2100 and the middle position of the U-shaped part 2101 are connected. One end of each of the two conduits 23 is connected to both ends of the U-shaped part 2101, and one end of the through pipe 22 is connected to the straight part 2100, so that after water flows into the second guide channel 210 from the through pipe 22, it can flow from both ends toward the first end block 20 toward the two conduits 23.

[0037] like Figure 2 , Figure 4 As shown, in one embodiment, the steam assembly further includes a plurality of short pipes 24, one end of each short pipe 24 being connected to each first guide groove 200, and the other end of each short pipe 24 being connected to a corresponding groove 100 on the base plate 10.

[0038] It should be noted that there are two short tubes 24. One end of each short tube 24 is connected to the end of each first guide groove 200 away from the guide tube 23. The other end of each short tube 24 is connected to the end of each of the two grooves 100. For example, both short tubes 24 are glued and fixed by waterproof and high temperature resistant adhesive, such as silicone sealant.

[0039] like Figure 2 , Figures 4 to 5 As shown, in one embodiment, the first end block 20 is further provided with a through groove 201, which passes through the two opposite ends of the first end block 20 and is located between each of the first guide grooves 200. The through pipe 22 passes through the through groove 201.

[0040] It should be noted that the through channel 201 is formed on the side of the first end block 20 near the bottom plate 10, and the two first guide channels 200 are located on both sides of the through channel 201. The two ends of the through channel 201 are respectively connected to the ends of the first end block 20 near the second end block 21 and the ends of the first end block 20 away from the second end block 21. Furthermore, the end of the pipe 22 away from the second end block 21 passes through the through channel 201, extends from the end of the first end block 20 away from the second end block 21, and is connected to the water source.

[0041] It should be noted that the first guide channel 200 tends to have a J-shaped structure. The two first guide channels 200 are located on both sides of the through channel 201, and the ends of the two first guide channels 200 away from the guide tube 23 are bent away from the through channel 201. When the first end block 20 is set on the base plate 10, the lower surface of the base plate 10 and the first end block 20 together surround each of the first guide channels 200, thereby enabling the guide tube 23, the first guide channels 200, the short tube 24 and the groove 100 to form an S-shaped channel.

[0042] like Figure 3 As shown, in one embodiment, a circular hole 101 is provided on the inner sidewall of the groove 100. The circular hole 101 communicates with the groove 100, and the end of the short tube 24 away from the first guide groove 200 extends into the groove 100 through the circular hole 101.

[0043] It should be noted that a circular hole 101 is provided on the inner wall of one end of the groove 100, and the two ends of the circular hole 101 are connected to the inner wall of the groove 100 and the outer wall of the bottom plate 10, respectively. In this way, the end of the short pipe 24 away from the first guide groove 200 can pass through the circular hole 101 and extend into the groove 100, thereby allowing water to flow into the groove 100.

[0044] like Figures 1 to 3 As shown, in one embodiment, the steam assembly further includes a cover plate 25, which covers the base plate 10. The cover plate 25 has a plurality of air holes 250, and each air hole 250 is connected to each groove 100.

[0045] It should be noted that when the cover plate 25 is placed on the base plate 10, the lower surface of the cover plate 25 and the groove 100 together form a water chamber, and the short pipe 24 communicates with the water chamber. Furthermore, the cover plate 25 has several vents 250, spaced apart from each other. The vents 250 are arranged in two rows at opposite ends of the cover plate 25, and each row communicates with one of the two water chambers. This allows steam within the water chambers to escape from the vents 250.

[0046] like Figures 1 to 3 As shown, in one embodiment, the cover plate 25 is further provided with a plate groove 251, which is located on the side of the cover plate 25 near the bottom plate 10. The plate groove 251 is used to install the heating plate.

[0047] It should be noted that a groove 251 is formed on the side of the cover plate 25 near the base plate 10, and both ends of the groove 251 are connected to both ends of the cover plate 25. When the cover plate 25 is placed on the base plate 10, the groove 251 and the upper surface of the base plate 10 together form a nearly square channel, and the heating plate is fitted into this square channel. This allows both the cover plate 25 and the base plate 10 to contact the heating plate. The cover plate 25 being placed on the base plate 10 allows the heating plate to heat both the cover plate 25 and the base plate 10 simultaneously, thereby improving heating efficiency. Furthermore, the cover plate 25, the base plate 10, the first end block 20, and the second end block 21 are all made of metal materials with high thermal conductivity; for example, the cover plate 25, the base plate 10, the first end block 20, and the second end block 21 are all made of aluminum alloy.

[0048] It should be noted that since both the first end block 20 and the second end block 21 are mounted on the base plate 10, the heating plate can heat the water in the groove 100 while simultaneously transferring heat to the first end block 20 and the second end block 21 through the base plate 10, thereby simultaneously heating the water in the second guide channel 210 and each of the first guide channels 200. This improves the water heating efficiency, thereby increasing the steam output and steam generation efficiency.

[0049] like Figures 2 to 3 As shown, in one embodiment, the base plate 10 is provided with a plurality of locking strips 102, and the cover plate 25 is also provided with a plurality of locking slots 252, the locking strips 102 engaging with the locking slots 252.

[0050] It should be noted that the upper surface of the base plate 10 near the cover plate 25 is provided with several retaining strips 102, with each pair of retaining strips 102 located on both sides of a groove 100. Furthermore, the lower surface of the cover plate 25 near the base plate 10 is provided with several retaining grooves 252. When the cover plate 25 is placed on the base plate 10, each retaining strip 102 is fitted into each retaining groove 252 in a corresponding manner to prevent water in the water chamber from flowing into the square channel from the side, and to prevent the water from being directly heated by the heating plate and generating steam in the square channel, which would prevent it from being ejected from the vent 250.

[0051] like Figure 2 As shown, in one embodiment, the cover plate 25 is also provided with a water tank 253, and each air hole 250 is connected to the water tank 253.

[0052] It should be noted that two water troughs 253 are formed on the upper surface of the cover plate 25 away from the groove 100. The two ends of the two water troughs 253 are respectively connected to the opposite ends of the cover plate 25. The end of each vent 250 away from the bottom plate 10 is connected to a water trough 253. In this way, the water condensed at the opening of the vent 250 due to steam ejected from each vent 250 can be discharged from both ends of the cover plate 25 for collection and recycling.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
