Description

Technical Field

[0001] This utility model belongs to the field of electric iron technology, and in particular relates to an anti-scalding electric iron. Background Technology

[0002] An electric iron is a tool for smoothing clothes and fabrics. It mainly consists of a soleplate, heating element, pressure plate, cover, and handle. The soleplate is made of cast iron or aluminum alloy and has a flat surface for ironing clothes. The heating element heats the soleplate to a certain ironing temperature. The cover is connected to and covers the soleplate to protect the hot soleplate and heating element from burns.

[0003] In the prior art, Chinese utility model patent CN211112831U discloses an anti-scalding electric iron, including an electric iron shell, a controller installed at the bottom of the electric iron shell, mounting frames embedded at both ends of the bottom of the electric iron shell, a movable plate slidably arranged between the inner walls of the two sides of the mounting frame, rollers installed at the bottom of the movable plate, a vertically arranged abutment rod fixed at the top center of the movable plate, a pressure sensor electrically connected to the controller fixed on the inner top surface of the mounting frame, and symmetrically arranged telescopic devices fixed between the inner top surface of the mounting frame and the movable plate. An adjustment plate is connected to one side of the telescopic device. Thus, under the combined action of all components, the on / off state of the electric iron can be controlled in time when it is resting while arranging clothes, preventing its temperature from being too high and damaging the clothes, thereby better meeting the needs of real life.

[0004] In the existing technology, the on / off state of the electric iron is controlled in a timely manner when it is stationary by the combined action of various components, so as to prevent the temperature from being too high and damaging the clothes. However, there is still a lack of mobility when the iron is in use as a whole.

[0005] First, in the aforementioned existing technology, although the iron can be switched on and off in time after ironing clothes, the soleplate of the iron still has residual heat, and the temperature is usually much higher than that of ordinary clothes. If it is not separated from the clothes in time, the clothing fibers will be scorched and yellowed, resulting in permanent damage.

[0006] Secondly, although existing technology can house the soleplate within the iron, this prevents it from dissipating heat effectively. Poor heat dissipation can accelerate the aging of internal components such as heating elements and thermostats, thus affecting the product's lifespan and ironing performance. Utility Model Content

[0007] In order to overcome the shortcomings of the prior art, this utility model provides a heat-resistant electric iron.

[0008] This invention solves the technical problem that the soleplate of existing electric irons still retains residual heat, and the temperature is usually much higher than the tolerance of ordinary clothing. If it is not isolated from the clothing in time, it will cause permanent damage to the clothing. On this basis, it also solves the problem that the soleplate cannot dissipate heat in time, achieving the effect of isolating the clothing and dissipating heat quickly.

[0009] To achieve the above objectives, this utility model provides the following technical solution: an anti-scalding electric iron, comprising an electric iron body, an L-shaped plate slidably mounted inside the electric iron body, a heating plate slidably mounted at the bottom of the L-shaped plate, a cooling box fixedly mounted inside the electric iron body, a piston slidably mounted inside the cooling box, a top post fixedly mounted on the top of the piston and fixedly mounted on one side of the L-shaped plate, and the top post slidingly engaging with the cooling box, a cooling plate fixedly mounted inside the electric iron body, a cooling groove formed inside the cooling plate, and the lower surface of the cooling plate abutting against the upper surface of the heating plate, an inlet pipe and a circulation pipe respectively connected to both ends of the cooling groove, the inlet pipe and the fixed plate being connected to the cooling box, and both the inlet pipe and the circulation pipe being connected to a one-way valve.

[0010] By using cooling plates, cooling tanks, circulation pipes, and cooling boxes, the ironing soleplate of the electric iron can be cooled, preventing insufficient heat dissipation. Poor heat dissipation can lead to accelerated aging of the internal components of the electric iron. At the same time, the coolant can circulate back and forth to dissipate heat, greatly improving the cooling effect.

[0011] In the aforementioned anti-scalding electric iron, a hollow fixing post is fixedly installed on the top of the iron body, a handle is fixedly installed on the top of the fixing post, a through groove is opened on one side of the fixing post, a rotating shaft is rotatably installed inside the fixing post, a pressure plate that rotates inside the through groove is fixedly installed on the surface of the rotating shaft, the pressure plate is hinged to an L-shaped plate, and a first spring is fixedly installed on the upper surface of one end of the pressure plate and the lower surface of one end of the handle.

[0012] By using a pivot and pressure plate, the internal structure of the electric iron body is controlled by the pressure plate during use, ensuring consistency in use.

[0013] In the aforementioned anti-scalding electric iron, the top of the L-shaped plate slides inside the fixed post, a second spring is fixedly installed between the upper surface of the inner cavity of the electric iron body and the surface of the L-shaped plate, and the top of the L-shaped plate cooperates with one end of the pressure plate located inside the fixed post.

[0014] By using the pressure plate and the second spring, the pressure plate can be rotated, which can control the up and down movement of the L-shaped plate, thereby controlling the internal device of the electric iron body.

[0015] In the aforementioned anti-scalding electric iron, the iron body has grooves installed on both sides inside, and sliders are slidably installed inside the grooves. The heating plate is fixedly installed between the two sliders.

[0016] By using the slide and slider, the heating plate can be controlled to slide up and down, allowing it to extend or retract from the iron body, thus isolating it from the clothes and preventing the residual heat from the heating plate from scorching or yellowing the clothing fibers and causing permanent damage.

[0017] In the aforementioned anti-scalding electric iron, a vertical rod is fixedly installed on the lower surface of the L-shaped plate, and the vertical rod is fixed to the upper surface of the slider.

[0018] In the aforementioned anti-scalding electric iron, a base plate is fixedly installed on the lower surface of the iron body, and multiple heat dissipation holes are provided at the bottom of the iron body.

[0019] The use of ventilation holes accelerates airflow inside the iron body, increasing the heat dissipation speed of the heating plate.

[0020] In the aforementioned anti-scalding electric iron, heat dissipation fins penetrating the outer side of the iron body are fixedly installed on both sides of the cooling box.

[0021] The use of heat dissipation fins allows the heat from the cooling box to be dissipated quickly, greatly improving the cooling effect.

[0022] In the aforementioned anti-scalding electric iron, a power-off switch is fixedly installed between the upper surface of the iron body and the lower surface of the pressure plate.

[0023] In summary, compared with the prior art, the anti-scalding electric iron provided by this utility model has the following beneficial effects:

[0024] 1. In this utility model, by using a cooling plate, cooling tank, circulation pipe and cooling box, the ironing soleplate of the electric iron can be cooled, avoiding the inability to cool in time. Poor heat dissipation will lead to accelerated aging of the internal components of the electric iron. At the same time, the coolant can flow back and forth to circulate and dissipate heat, which greatly improves the cooling effect.

[0025] 2. In this utility model, by using a pressure plate, an L-shaped plate, a vertical rod, a heating plate, and a power-off switch, the power can be cut off in time when the electric iron stops working, stopping the heating. At the same time, it can isolate the iron from the clothes, preventing the residual heat of the ironing plate from scorching or yellowing the clothing fibers and causing permanent damage, thus greatly improving the performance.

[0033] To enable those skilled in the art to better understand the present invention, 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.

[0034] Example 1:

[0035] refer to Figure 1 A heat-resistant electric iron includes an iron body 10, a soleplate 11 fixedly installed at the bottom of the iron body 10, a hollow fixing post 12 fixedly installed on the upper surface of the iron body 10, and a handle 13 fixedly installed on the top of the fixing post 12. When in use, the iron body 10 is moved by the handle 13 to iron clothes.

[0036] Example 2:

[0037] A heat-resistant electric iron, based on Embodiment 1, is further illustrated in the following embodiments, with reference to... Figures 1-3A through groove 14 is provided on one side of the fixed column 12. A rotating shaft 15 is rotatably installed inside the fixed column 12. A pressure plate 16 is fixedly installed on the surface of the rotating shaft 15 and rotates inside the through groove 14. A first spring 17 is fixedly installed on the upper surface of one end of the pressure plate 16 and the lower surface of one end of the handle 13. When using, the user holds the pressure plate 16 and the handle 13 together when ironing, so that the pressure plate 16 squeezes the first spring 17, and the end of the pressure plate 16 away from the first spring 17 rotates downward through the rotating shaft 15.

[0038] Further reference Figure 3 An L-shaped plate 18 extends through the top of the iron body 10, and the top of the L-shaped plate 18 slides inside the fixed post 12. The top of the L-shaped plate 18 is hinged to the pressure plate 16. A second spring 19 is fixedly installed between the upper surface of the inner cavity of the iron body 10 and the surface of the L-shaped plate 18. A vertical rod 28 is fixedly installed on the lower surface of the L-shaped plate 18. In use, when the end of the pressure plate 16 located inside the fixed post 12 rotates downward, it drives the L-shaped plate 18 to slide downward and stretches the second spring 19, thereby also driving the vertical rod 28 to move downward.

[0039] Further reference Figure 3 and Figure 4 The iron body 10 has sliding grooves 31 fixed on both sides inside. Sliding sliders 29 are slidably installed inside the sliding grooves 31. A heating plate 30 corresponding to the iron body 10 is fixedly installed between the two sliding sliders 29. The upper surface of one of the sliding sliders 29 is fixed to the bottom end of the vertical rod 28. When in use, as the vertical rod 28 moves down, the heating plate 30 moves down through the sliding slider 29, pushing the heating plate 30 out of the iron body 10 to iron the clothes. After the work is finished, the pressure plate 16 can be released. The pressure plate 16 and the L-shaped plate 18 are reset by the elastic force of the first spring 17 and the pulling force of the second spring 19, thereby putting the heating plate 30 into the iron body 10. The heating plate 30 is located above the soleplate 11, thus isolating the heating plate 30 from the clothes and preventing the residual heat of the heating plate 30 from scorching or yellowing the clothing fibers and causing permanent damage, greatly improving the use effect.

[0040] Furthermore, participate in Figure 1 A power-off switch 34 is fixedly installed between the upper surface of the iron body 10 and the lower surface of the pressure plate 16. When ironing clothes, the pressure plate 16 moves upward, causing the power-off switch 34 to close and power on. After ironing is completed, the pressure plate 16 resets, causing the power-off switch 34 to open, cutting off the circuit and controlling the on / off state in time to prevent the temperature from being too high and damaging the clothes.

[0041] Example 3:

[0042] A heat-resistant electric iron, based on Embodiment 2, is further illustrated in the following embodiment, for reference. Figure 2 The electric iron body 10 has a cooling box 21 fixedly installed inside. The fixed plate 20 is filled with coolant. A piston 22 is slidably installed inside the cooling box 21. A top post 23 that penetrates the cooling box 21 is fixedly installed on the upper surface of the piston 22. The top post 23 slides with the upper surface of the cooling box 21. A fixed plate 20 that is fixed to the piston 22 is fixedly installed on one side of the L-shaped plate 18. When in use, as the L-shaped plate 18 moves downward, the top post 23 and the piston 22 move downward through the fixed plate 20 to discharge the coolant.

[0043] Further reference Figure 3 and Figure 6 A cooling plate 25 is fixedly installed inside the electric iron body 10. The cooling plate 25 is located on the upper surface of the heating plate 30. A cooling groove 27 is formed inside the cooling plate 25, and the cooling groove 27 is half-filled with coolant. One end of the cooling groove 27 is connected to an inlet pipe 24, and the other end is connected to a circulation pipe 26. Both the inlet pipe 24 and the circulation pipe 26 are connected to the cooling tank 21, and both the inlet pipe 24 and the circulation pipe 26 have a one-way valve at the connection point. When ironing clothes, the piston 22 moves down, and coolant is injected through the inlet pipe 24. The coolant is poured into the cooling tank 27 and filled to the brim. The one-way valve connected to the inlet pipe 24 allows the coolant to flow downwards. After the clothes are ironed, the piston 22 moves upwards, and the negative pressure draws half of the coolant in the cooling tank 27 into the cooling box 21 through the circulation pipe 26. The one-way valve connected to the circulation pipe 26 allows the coolant to flow into the cooling box 21, so that half of the coolant remains in the cooling tank 27 to quickly cool the heating plate 30. This design enables the coolant inside the cooling tank 27 to circulate, greatly improving the cooling effect.

[0044] Further reference Figure 1 and Figure 5 The bottom of the electric iron body 10 has multiple heat dissipation holes 33, which are used to accelerate the air circulation inside the electric iron body 10 and improve the heat dissipation speed of the heating plate 30.

[0045] Further reference Figure 5 The cooling box 21 is fixedly installed on both sides with heat dissipation fins 32 that penetrate the outer side of the iron body 10, which can quickly dissipate the heat of the cooling box 21 and greatly improve the cooling effect.

[0046] Working principle: During operation, the user holds the pressure plate 16 and handle 13 together while ironing, causing the pressure plate 16 to compress the first spring 17. The end of the pressure plate 16 away from the first spring 17 rotates downwards via the pivot 15, causing the L-shaped plate 18 to slide downwards and stretching the second spring 19. This also causes the vertical rod 28 to move downwards. Simultaneously, the vertical rod 28 moves downwards, causing the heating plate 30 to move downwards via the slider 29, pushing the heating plate 30 out of the iron body 10 to iron the clothes. While the L-shaped plate 18 moves downwards, the fixed plate 20 causes the top column 23 and piston 22 to move downwards, thus forcing coolant from the inlet pipe 24 into the cooling tank 27. After ironing, the elastic force of the first spring 17 and the tension of the second spring 19 cause the pressure plate 16 and L-shaped plate 18 to return to their original positions. The heating plate 30 is retracted into the iron body 10, thus isolating it from the clothing. Simultaneously, the pressure plate 16 resets, opening the power-off switch 34 to cut off the circuit and control the on / off state, preventing overheating and damage to the clothing. At the same time, the piston 22 moves upward, and the negative pressure draws half of the coolant in the cooling tank 27 into the cooling box 21 through the circulation pipe 26. The one-way valve connected to the circulation pipe 26 only allows coolant to flow into the cooling box 21, leaving half of the coolant in the cooling tank 27 for rapid cooling of the heating plate 30. This design allows the coolant inside the cooling tank 27 to circulate, greatly improving the cooling effect. The heat dissipation holes 33 increase the heat dissipation speed of the heating plate 30, and the heat dissipation fins 32 quickly dissipate the heat from the cooling box 21, further enhancing the cooling effect.
