Abstract
Description
Technical Field
[0001] This invention relates to the field of hair perming heating cover technology, specifically a hair perming heating cover with waste heat utilization. Background Technology
[0002] A perm heating pad is a common hair styling tool that provides stable heat to help hair care products penetrate better or to assist in setting permed or dyed hair.
[0003] Existing hair perming heating covers typically employ multiple heating structures, such as heating wires, to heat and dry the hair. During the heating process, most of the heat generated is directly dissipated into the surrounding air through the outer shell of the heating cover, resulting in low heat utilization. In particular, after heating ends and the equipment is turned off, a large amount of residual heat remains in the heating structure and outer shell. This heat cannot be effectively utilized and is eventually dissipated into the environment through the outer shell, causing further waste of heat energy.
[0004] To address the aforementioned issues, we propose a hair perming heating cover that utilizes residual heat. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides a hair perming heating cover with waste heat utilization. By using a phase change material as a heat storage medium, and utilizing its high latent heat characteristics, it actively absorbs and stores excess heat generated inside the hair perming heating cover during the heating process. The phase change material converts thermal energy into latent heat storage. When the heating structure stops working or the temperature drops, the stored heat is slowly released into the space inside the cover. This allows the heat energy that would otherwise be lost to the air through the outer shell to be recovered and utilized, significantly improving the thermal energy utilization rate and avoiding the ineffective waste of heat during the heating process and after shutdown.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a hair perming heating cover with waste heat utilization, comprising a lifting rod, a control end block rotatably mounted on the top of the lifting rod, and adjustment slot blocks fixedly mounted on both opposite sides of the control end block, a reduction adjustment motor fixedly mounted on the inner wall of each of the two adjustment slot blocks, a hook and a steam cover provided on the upper outer side of the lifting rod, a heating arc groove plate fixedly mounted on the front of the control end block, adjustment arc groove plates fixedly mounted on the output ends of each of the two reduction adjustment motors, and a steam generator fixedly mounted on the upper side of the steam cover on the lifting rod wall; Both of the aforementioned regulating arc groove plates have heating chambers inside, and the inner walls of both heating chambers are provided with heat dissipation bends. The heating arc groove plates have storage chambers and circulation chambers arranged sequentially from the inside to the outside. An output cavity is provided inside the control block on the side near the heating arc groove plate, and a hot water circulation pump is fixedly installed on the lower side inside the output cavity. A second silicone hose is fixedly installed at the output end of the hot water circulation pump.
[0007] Furthermore, a lifting rod fixing knob is provided on one side of the lifting rod surface, and a support base is fixedly installed at the bottom of the lifting rod. The reduction adjustment motor is a worm gear reducer motor, which can ensure the limiting positioning effect after the belt structure rotates to a certain position.
[0008] Furthermore, the steam hood is attached to the hook, and the surface of the hook is fixedly connected to the surface of the lifting rod. The steam generator ensures the connection between the steam hood and the heating arc groove plate, and can transport the preheated hot water in the heating arc groove plate to ensure the normal use of the steam hood.
[0009] Furthermore, both ends of the heat dissipation bend extend through to the surface of the adjusting arc groove plate, and a first silicone hose is fixedly installed between the corresponding ends of the two heat dissipation bends, which connects the two heat dissipation bends to each other.
[0010] Furthermore, L-shaped inlet pipes are fixedly installed on opposite sides of the inner walls of the storage chamber and the circulation chamber, and check valves are installed on the upper side of the walls of the two L-shaped inlet pipes. The check valves prevent liquid from flowing out of the storage chamber and the circulation chamber, allowing only external substances to enter the two chambers. In addition, the L-shaped inlet pipes in the circulation chamber can be connected to external liquid conveying equipment during use, so as to replenish the liquid when the steam generator is in use.
[0011] Furthermore, several pressure relief grooves are provided on the left and right sides below the inner wall of the storage cavity, and fluorosilicone rubber sheets are fixedly installed on the upper side of the inner wall of the several pressure relief grooves. The interior of the storage cavity is filled with paraffin wax, and the deformability of the fluorosilicone rubber sheets is used to adapt to the volume deformation of the paraffin wax filling the storage cavity.
[0012] Furthermore, the input end of the hot water circulation pump extends through the surface of the heating arc groove plate to the lower side of the inner wall of the circulation chamber, while the upper end of the second silicone hose extends through to the surface of the control end block, and the upper end of the second silicone hose is fixedly connected to one end of one of the heat dissipation bends, while a third silicone hose is fixedly installed on one end of the other heat dissipation bend.
[0013] Furthermore, the lower end of the third silicone hose extends through to one side of the inner wall of the circulation chamber, and the third silicone hose extends to the side of the circulation chamber away from the hot water circulation pump. The lower side of the inner wall of the circulation chamber, near the hot water circulation pump, is provided with an outlet end. The outlet end can be combined with the steam hood to discharge excess water in the circulation chamber. In this way, the liquid in the circulation chamber will first be drawn out by the hot water circulation pump, introduced into the surface of a heat dissipation bend through the second silicone hose, then enter another heat dissipation bend through the first silicone hose, and finally enter the circulation chamber through the third silicone hose, thus achieving liquid circulation. The residual heat is used to ensure the auxiliary heating effect of hair dyeing heating, and the liquid added in the circulation chamber can provide preheated warm water for the steam hood. This application is used in combination with the steam hood. The L-shaped inlet pipe continuously outputs liquid, and there will be no problem of liquid boiling, which can ensure the normal use of the device. Even if the steam hood does not use the L-shaped inlet pipe, water is added intermittently and discharged through the outlet end, which will not affect the normal use of the device.
[0014] Furthermore, the two heat dissipation bends are respectively arranged around the inside of the heating cavity, and the heat dissipation bends are made of aluminum alloy, with the outer wall of the heat dissipation bends in contact with the inner wall of the heating cavity.
[0015] Furthermore, several protective plates are fixedly installed on the lower sides of the two adjusting arc groove plates and the lower sides of the heating arc groove plate, and the several corresponding protective plates are distributed at equal intervals.
[0016] Compared with the prior art, the present invention provides a hair perming heating cover with waste heat utilization, which has the following beneficial effects: 1. This device uses phase change material as a heat storage medium and takes advantage of its high latent heat characteristics to actively absorb and store the excess heat generated inside the hair perming heating cover during the heating process. The phase change material converts thermal energy into latent heat storage. When the heating structure stops working or the temperature drops, the stored heat is slowly released into the space inside the cover. This allows the heat energy that would otherwise be lost to the air through the outer shell to be recovered and reused, which significantly improves the thermal energy utilization rate and avoids the ineffective waste of heat during the heating process and after shutdown.
[0017] 2. The device also reduces the number of heating structures, thereby reducing real-time heating power and total power consumption while ensuring the required temperature for hair styling. At the same time, the residual heat released by the phase change material after shutdown can maintain the effective temperature inside the enclosure for a period of time, further reducing the reliance on continuous power supply for heating and achieving energy saving and consumption reduction.
[0018] 3. This device uses collected heat to preheat the water inside. The preheated water can be directly used to generate steam, thereby realizing the steam treatment function in the perming process. It relies on the recovered waste heat to complete the preheating, which greatly reduces the extra energy consumption for steam generation. Compared with traditional devices, the preheating method of this device is more energy-efficient and effective. Attached Figure Description

[0021] 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.
[0022] Please see Figures 1 to 13 In this embodiment, a hair perming heating cover with waste heat utilization includes a vertically arranged lifting rod 1. A support base 102 is fixedly installed at the bottom of the lifting rod 1 to stably place the entire device on a workbench or the ground. A lifting rod fixing knob 101 is provided on one side of the upper rod wall of the lifting rod 1 to adjust the extension height of the lifting rod 1 and lock it. A control end block 2 is rotatably mounted on the top of the lifting rod 1. The control end block 2 can rotate horizontally around the axis of the lifting rod 1 to adjust the perming angle. Adjustment slot blocks 3 are fixedly mounted on opposite sides of the control end block 2. A reduction adjustment motor 4 is fixedly mounted on the inner wall of each adjustment slot block 3. The reduction adjustment motor 4 is preferably a worm gear reduction motor. Utilizing the self-locking characteristics of the worm gear, it can achieve limit positioning after driving the relevant components to rotate to any angle, preventing displacement due to gravity or external force. A heating arc groove plate 7 is fixedly installed on the front of the control block 2. An adjustment arc groove plate 8 is fixedly installed on the output end of the two reduction adjustment motors 4 respectively. The adjustment arc groove plate 8 is located on the left and right sides of the heating arc groove plate 7 and can rotate around the vertical axis under the drive of the reduction adjustment motor 4 to fit the hairline curvature of different head shapes. A hook 5 and a steam hood 6 are provided on the upper outer side of the lifting rod 1. Specifically, the hook 5 is fixedly connected to the surface of the lifting rod 1, and the steam hood 6 is hung on the hook 5 and can be freely removed and placed. A steam generator 9 is fixedly installed on the rod wall of the lifting rod 1, located on the upper side of the steam hood 6. The steam generator 9 is used to generate steam. Its liquid inlet is connected to the preheated liquid inside the heating arc groove plate 7 through a pipeline, and its steam outlet is connected to the steam hood 6 to provide steam treatment function to the hair. Heating chambers 10 are provided inside both adjusting arc groove plates 8. Heat dissipation bends 11 are arranged around the inner wall of the heating chamber 10. The two heat dissipation bends 11 are respectively arranged around the interior of their respective heating chambers 10. The heat dissipation bends 11 are made of aluminum alloy, and the outer wall of the heat dissipation bends 11 is in contact with the inner wall of the heating chamber 10. This contact arrangement allows the heat dissipation bends 11 to contact the heating chamber 10 with a large area, thereby efficiently transferring the heat inside the tube to the adjusting arc groove plate 8 and achieving uniform auxiliary heating. The heating arc groove plate 7 has a storage cavity 12 and a circulation cavity 13 arranged sequentially from the inside to the outside. The storage cavity 12 is located on the side closer to the hair and is filled with paraffin wax, a phase change heat storage material. Multiple pressure relief grooves 1201 are provided on the left and right sides of the lower inner wall of the storage cavity 12. A fluorosilicone rubber sheet 1202 is fixedly installed on the upper side of the inner wall of each pressure relief groove 1201. The deformable properties of the fluorosilicone rubber sheet 1202 can adapt to the volume expansion or contraction of paraffin wax during the solid-liquid phase change process, thus preventing the storage cavity 12 from being damaged due to excessive pressure. The circulation chamber 13 is used to contain a liquid medium, which can serve as a heat exchange carrier and a water source for the steam generator 9. An output chamber 14 is provided inside the control block 2 on the side near the heating arc groove plate 7. A hot water circulation pump 15 is fixedly installed on the lower side inside the output chamber 14. The input end of the hot water circulation pump 15 passes through the surface of the heating arc groove plate 7 and extends to the lower side of the inner wall of the circulation chamber 13 for drawing liquid from the circulation chamber 13. A second silicone hose 16 is fixedly installed on the output end of the hot water circulation pump 15. The upper end of the second silicone hose 16 passes through and extends to the surface of the control block 2 and is fixedly connected to one end of one of the heat dissipation bends 11. The structural relationship between the two heat dissipation bends 11 is as follows: both ends of each heat dissipation bend 11 extend through to the surface of the corresponding adjustment arc groove plate 8. A first silicone hose 1101 is fixedly installed between the corresponding ends of the two heat dissipation bends 11. The first silicone hose 1101 connects the two heat dissipation bends 11 to each other. The other heat dissipation bend 11, that is, the heat dissipation bend 11 that is not connected to the second silicone hose 16, has a third silicone hose 1501 fixedly installed at one end. The lower end of the third silicone hose 1501 extends through to one side of the inner wall of the circulation chamber 13, and the extension position is located on the side of the circulation chamber 13 away from the hot water circulation pump 15. In addition, L-shaped inlet pipes 1301 are fixedly installed on opposite sides of the inner walls of the storage chamber 12 and the circulation chamber 13. Each L-shaped inlet pipe 1301 is equipped with a check valve 1302 on the upper side of its pipe wall. The check valve 1302 prevents external substances, such as replenished liquid, from entering the storage chamber 12 or the circulation chamber 13, while preventing the liquid or paraffin in the chamber from flowing back out. The L-shaped inlet pipe 1301 in the circulation chamber 13 can be connected to an external liquid conveying device during use so that liquid can be continuously or intermittently replenished when the steam generator 9 is working. A discharge end 1502 is also provided on the lower side of the inner wall of the circulation chamber 13 near the hot water circulation pump 15. The discharge end 1502 can be connected to the steam hood 6 through a pipeline to supply preheated warm water to the steam generator 9, and can also be used as a drain outlet to discharge excess water in the circulation chamber 13. Multiple protective plates 17 are fixedly installed on the lower side of the interior of the two adjusting arc groove plates 8 and the lower side of the interior of the heating arc groove plate 7. The multiple protective plates 17 are evenly distributed. The protective plates 17 are made of heat-resistant insulating material and are used to prevent the user's scalp or hair roots from directly contacting the inner wall of the high-temperature heating arc groove plate 7 or adjusting arc groove plate 8, so as to play the role of heat insulation and preventing burns.
[0023] The working principle of the hair perming heating cover with waste heat utilization described in this application is as follows: When the hair perming heating cover is powered on and starts working, the electric heating element inside the heating arc groove plate 7 (a standard setting, shown in the attached figure) generates heat. Part of this heat is directly used to heat the hair to achieve hair perming and styling, and the other part is transferred to the storage cavity 12, where it is absorbed by the paraffin wax filled inside. When the paraffin wax reaches the phase change temperature, it undergoes a solid-liquid phase change and stores a large amount of heat energy in the form of latent heat. The pressure relief groove 1201 and the fluorosilicone rubber sheet 1202 elastically deform outward when the volume of paraffin wax expands, maintaining the pressure stability inside the storage cavity 12. At the same time, the hot water circulation pump 15 starts, drawing out the room temperature liquid in the circulation chamber 13, which flows through the second silicone hose 16, a heat dissipation bend 11, the first silicone hose 1101, another heat dissipation bend 11, and finally returns to the circulation chamber 13 through the third silicone hose 1501, forming a closed circulation loop. During the flow through the two heat dissipation bends 11, since the heat dissipation bends 11 are made of aluminum alloy and are in close contact with the inner wall of the heating chamber 10, the liquid in the heat dissipation bends 11 will be gradually heated along with the liquid in the circulation chamber 13, and the temperature will rise. The preheated liquid will return to the circulation chamber 13, so that the circulation chamber 13 as a whole maintains a high water temperature. The preheated warm water in the circulation chamber 13 can be delivered to the steam generator 9 through the outlet 1502. The steam generator 9 further heats the warm water to boiling or atomization, generates steam and sends it into the steam hood 6 to steam the hair. Since the water entering the steam generator 9 has been preheated, the additional heating power required by the steam generator 9 is significantly reduced, thus achieving energy saving. On the other hand, even if the steam function is not activated, the hot water in the circulation chamber 13 can still continuously absorb and utilize the residual heat released by the paraffin through the above circulation to maintain the temperature inside the hair perming heating cover, thereby reducing the frequency of power on and off of the electric heating element or reducing its output power, achieving the effect of auxiliary heating and energy saving. During use, when the liquid in the circulation chamber 13 decreases due to usage, it can be replenished from the outside through the L-shaped inlet pipe 1301 and the check valve 1302. The replenishment process does not affect the normal operation of the circulation pump. The check valve 1302 ensures that the liquid can only flow in one direction and prevents backflow. If the steam hood 6 is not used or does not require steam, the L-shaped inlet pipe 1301 can be changed to intermittent water addition. Excess water is discharged through the outlet 1502, which will not affect the basic heating function of the hair perming heating hood. According to the hair perming needs, the operator can drive the speed reduction adjustment motor 4 to rotate through the control end block 2, so that the adjustment arc groove plate 8 swings, thereby adjusting the contact angle between the left and right adjustment arc groove plates 8 and the hair. Since the speed reduction adjustment motor 4 adopts a worm gear structure, its self-locking characteristic can ensure that the adjustment arc groove plate 8 remains fixed at any stop position without the need for an additional locking device. This embodiment achieves efficient collection and reuse of heat generated during the perming process by setting up a paraffin heat storage structure in the storage chamber 12, a liquid circulation loop in the circulation chamber 13, and a connecting structure of the heat dissipation bend 11. After the machine is turned off, the residual heat slowly released by the paraffin can still be utilized through the circulating liquid, avoiding the problem of heat loss and waste through the outer shell of the traditional perming heating cover. At the same time, since the residual heat assists the heating, the number or power of the heating elements can be appropriately reduced, thus reducing the overall energy consumption. The steam generator 9 uses preheated warm water to generate steam, further reducing the energy consumption of steam preparation.
[0024] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
