Description

Technical Field

[0001] This invention relates to the field of steam generation technology, specifically to a steam generation and steam output device. Background Technology

[0002] As people pay more and more attention to their appearance, a wide variety of hair styling devices have appeared on the market, including hair straighteners for making hair smoother. To achieve better styling results, heat is usually used to treat the hair.

[0003] To prevent hair from becoming dry and frizzy due to high temperature and water loss during the hot straightening process, current hair straighteners usually have a steam generator added to them. The high-temperature steam generated by the heat is used to moisturize the hair, thus protecting it and helping with styling.

[0004] However, existing hair straightener steam generators have significant drawbacks: First, the existing heating channel design is unreasonable, resulting in a short residence time of the introduced water in the heating chamber, which fails to evaporate sufficiently. This leads to excessive moisture content in the output steam, making it easy for hot water droplets to spray out, resulting in poor styling effects and the risk of scalding the user. Second, the existing steam outlet channel design is simple, resulting in extremely uneven steam distribution in the misting area. The steam volume is large near the air inlet, while the steam volume is small or even non-existent far from the air inlet, seriously affecting the hair styling experience and the setting effect. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a steam generator and steam outlet device, which solves the technical problems of insufficient water evaporation leading to water droplet spraying and uneven mist output due to uneven pressure distribution in the steam outlet channel.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a steam generating and steam output device, comprising a heating box, a heating element, and a steam generating pipe, wherein the steam generating pipe is disposed inside the heating box and is in thermal conductive contact with the heating element, and the steam generating pipe has a water inlet and a steam outlet. The steam outlet end is connected to a steam outlet channel. The bottom and / or top of the steam outlet channel are inclined relative to the horizontal plane, so that the cross-sectional area of ​​the steam outlet channel gradually decreases along the steam flow direction, forming a V-shaped structure. A gas equalization component is also provided between the steam outlet channel and the external environment, and the gas equalization component has several steam holes.

[0007] Preferably, the steam generating pipe extends in a curved shape inside the heating box, and the path from the water inlet to the steam outlet of the steam generating pipe is not straight.

[0008] Preferably, the cross-sectional area of ​​the steam outlet channel on the inlet side is larger than the cross-sectional area on the side away from the inlet; a steam plate is provided above the steam outlet channel, and the steam holes are opened on the steam plate; The outer diameter of the steam pore is less than or equal to the inner diameter.

[0009] Preferably, a pressure equalization chamber and / or a gas equalization plate are further provided between the steam outlet end of the steam generating pipe and the steam outlet channel; The cross-sectional area of ​​the pressure equalization chamber is larger than the cross-sectional area of ​​the water inlet end of the steam generating pipe, and the volume of the pressure equalization chamber is larger than the volume of the steam outlet of the steam outlet channel. The gas equalization plate is located between the steam outlet channel and the steam hole, and the gas equalization plate is made of porous ceramic or steel mesh.

[0010] Preferably, the steam outlet end of the steam generating pipe is provided with a plug, and the plug has a channel inside that connects the steam generating pipe and the pressure equalization chamber; the plug is installed on one side of the heating box.

[0011] Preferably, the heating box is divided into a double-layer structure by a partition, the heating element is fixedly connected to the top layer of the double-layer structure, and the steam generating pipe is fixedly connected to the bottom layer of the double-layer structure. The heating element and the steam generating pipe are both installed close to the partition; a cover plate is fixedly connected to the bottom of the heating box.

[0012] Preferably, the top of the heating box is provided with a heat-resistant seal, which is made of silicone. The silicone is disposed between the heating box and the steam plate, and the gas equalization component includes a gas equalization plate disposed between the top of the silicone and the steam plate; The steam plate and silicone are fixedly connected to the heating box by screws.

[0013] Working principle: During operation, an external water pump injects water into the inlet of the steam generating pipe 8. The water flows along a curved heating path and is rapidly heated and vaporized by the heat transferred by the baffle. The generated high-temperature steam enters the larger pressure equalization chamber through the plug 4 for buffering, and then enters the V-shaped steam outlet channel. As the cross-sectional area of ​​the channel gradually decreases with the flow direction, the steam pressure remains uniform throughout the channel. Subsequently, the steam is refined through the gas equalization plate 2, and finally sprayed vertically, uniformly, and in large quantities through the gas gathering holes on the steam plate 1, acting on the hair.

[0014] This invention provides a steam generator and steam outlet device. It has the following beneficial effects: 1. This invention designs the heating channel path of the steam generating pipe as curved, so that the channel between the water inlet and the steam outlet is not a straight line. This significantly extends the flow path and heating time of water in the heating source, ensuring that the water can be fully heated and completely converted into steam. This effectively avoids the problem of small water droplets spraying out due to incomplete evaporation, and improves the safety of use and the hair care effect.

[0015] 2. This invention designs the steam outlet channel as a V-shaped structure with a gradually decreasing cross-sectional area along the flow direction (i.e., the cross-sectional area is large near the air inlet and small away from the air inlet). By utilizing the principles of fluid mechanics, this invention compensates for the pressure loss of steam during transmission, making the steam pressure as uniform as possible throughout the outlet channel. This achieves uniform steam distribution in the misting area and solves the problem of uneven steam output in the prior art.

[0016] 3. This invention sets up a pressure equalization chamber and a gas equalization plate between the gas outlet and the gas outlet channel. The large volume of the pressure equalization chamber buffers and stores the incoming high-speed steam, and the porous structure of the gas equalization plate disperses the airflow, further refining the steam and making the gas distribution more uniform, which greatly improves the fineness and uniformity of the mist.

[0017] 4. By designing the final output steam hole with an external aperture smaller than or equal to the internal aperture, this invention acts as a steam-gathering nozzle, which can accelerate and rectify the discharged steam, making the ejected steam more vertical and powerful, avoiding steam dispersion, and improving the steam penetration efficiency into the hair.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0021] like Figure 1-4 As shown, this embodiment of the invention provides a steam generating and steam output device, mainly used in hair styling equipment such as hair straighteners and perms. The device mainly includes a heating box 6, a heating element 7, a steam generating pipe 8, and components for homogenizing the steam.

[0022] like Figure 1 and Figure 3 As shown, the heating box 6 serves as the main support component, used to house and install the device components. The interior of the heating box 6 is divided into a double-layer structure by a central partition. The top layer houses a heating element 7, whose connector passes through the heating box 6 to connect to a power source. The bottom layer houses a steam generating pipe 8, with both ends of the pipe passing through the heating box 6. To ensure efficient heat transfer, both the heating element 7 and the steam generating pipe 8 are positioned close to the central partition, allowing the heat generated by the heating element 7 to be quickly transferred to the water flow within the steam generating pipe 8. A cover plate 9 is fixedly connected to the bottom of the heating box 6 to enclose the bottom space and secure the internal components.

[0023] like Figure 2 and Figure 3 As shown, to address the problem of insufficient water evaporation in existing technologies, the steam generating pipe 8 in this embodiment is not a straight-through design inside the heating chamber 6, but rather extends in a curved shape (e.g., S-shaped or coiled). After water is injected from the inlet, it is continuously heated by the heat transferred from the heating source throughout the entire channel. The curved path makes the heating channel longer, increasing the residence time of the water flow in the high-temperature zone, thereby ensuring that the outflowing fluid is fully evaporated high-temperature steam and eliminating the phenomenon of water droplets.

[0024] After steam is generated from steam generator pipe 8, it is not discharged directly, but undergoes a series of pressure equalization processes. First, as... Figure 2 and Figure 3 As shown, a plug 4 is connected to the steam outlet of the steam generating pipe 8, and a channel is opened on one side of the plug 4 to enter the pressure equalization chamber. The pressure equalization chamber is set inside the heating box 6 or the silicone 5 structure. Its characteristics are that the cross-sectional area is much larger than the cross-sectional area of ​​the water inlet of the steam generating pipe 8, and its volume is large (larger than the volume of the final steam outlet). The gas entering the pressure equalization chamber is stored and buffered here to eliminate pulsating airflow and make the gas pressure initially stable.

[0025] Secondly, such as Figure 4As shown, steam enters the steam outlet channel after passing through the pressure equalization chamber. The bottom and top of this steam outlet channel are not parallel lines, but rather at a certain angle, forming a V-shaped structure. Specifically, the cross-sectional area of ​​the channel near the inlet (i.e., the side near plug 4) is larger, while the cross-sectional area further away from the inlet is smaller. This V-shaped design aims to balance fluid pressure, ensuring that as steam flows further away, although the flow rate decreases, the narrowing of the channel maintains relatively stable velocity and pressure, thus making the steam pressure as uniform as possible along the entire length of the outlet channel.

[0026] Finally, a two-stage homogenization structure is installed before the steam is discharged to the outside. The first stage is a steam equalization plate: such as... Figure 2 and Figure 3 As shown, a heat-resistant sealing silicone 5 is installed at the top of the heating chamber 6. A gas-distributing plate 2 (which can be a porous ceramic material or steel mesh) is sandwiched between the top of the silicone 5 and the outermost steam plate 1. The gas-distributing plate 2 uses its dense pores to disperse the steam, further ensuring a uniform gas distribution. The second stage is the steam holes: after passing through the gas-distributing plate 2, the steam exits through the steam holes on the steam plate 1. The steam holes are designed with a conical or straight hole structure where the outer diameter is smaller than or equal to the inner diameter. This utilizes the constriction effect to achieve a gas-gathering effect, ensuring that the ejected steam is directed vertically towards the hair, avoiding scattering.

[0027] A silicone rubber 5 is installed on the top of the heating chamber 6, and a steam plate 1 is installed on the outside of the silicone rubber 5. A plug 4 is installed on one side of the silicone rubber 5. Two screws 3 are installed on the other side of the silicone rubber 5 and on the plug 4, and one end of the screw 3 is threadedly connected to the heating chamber 6, thereby tightly locking the steam plate 1, the steel mesh 2, and the silicone rubber 5 on the heating chamber 6 to form a sealed steam flow channel.

[0028] like Figure 5 As shown, in this embodiment, the steam generating pipe 8 can also be arranged around the heating box along its length.

[0029] like Figure 6 As shown, the steam generating pipe 8 in this embodiment can also be configured as a spiral shape, surrounding the outside of the rod-shaped heating element 7.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
