Description

Technical Field

[0001] This utility model relates to the field of handheld garment steamer technology, specifically to a silicon controlled rectifier water-cooled heat dissipation integrated structure for a handheld garment steamer. Background Technology

[0002] In handheld garment steamers and similar electronic devices operating in confined spaces, the current technology for heat dissipation of SCRs (Silicon Controlled Rectifiers) generally adopts a direct-attach aluminum alloy heat sink solution. This is applicable to various small appliances requiring SCR voltage and current regulation within a relatively compact space. Structurally, the SCR is directly attached to the surface of a relatively large aluminum alloy heat sink. The principle is to utilize the excellent thermal conductivity of aluminum alloy to transfer the heat generated by the SCR to the heat sink through thermal conduction. Then, through the contact between the heat sink and the air, the heat is dissipated into the surrounding environment via natural convection or forced convection with the assistance of a small fan.

[0003] The internal space of existing handheld garment steamers is extremely small. Traditional aluminum alloy heat sinks require a certain size (to ensure effective heat dissipation area), making it difficult to arrange them reasonably in a limited space. They are prone to spatial interference with other components (such as water tanks, steam generating components, etc.), resulting in the inability to assemble the equipment properly or affecting the overall structural compactness.

[0004] Existing handheld garment steamers have limited heat dissipation efficiency, relying solely on heat conduction from aluminum alloy heat sinks and air convection for heat dissipation. In the relatively enclosed and poorly ventilated space of a handheld garment steamer, heat dissipation is slow. When the thyristor operates under continuous high load, heat accumulates, which can easily cause the thyristor temperature to become too high, affecting its operational stability (such as reduced voltage regulation and current control accuracy). It may even damage the thyristor due to overheating, reducing the overall reliability and lifespan of the equipment. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a silicon controlled rectifier (SCR) water-cooled heat dissipation integrated structure for a handheld garment steamer, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a handheld garment steamer with a silicon controlled rectifier (SCR) water-cooled heat dissipation integrated structure, including a base, a handle fixed to one side of the top of the base, an outer shell fixed through the top of the handle, an air vent plate fixed to one end of the outer shell, a micro water pump fixed in the middle of the inner wall of the handle, a first water guide pipe sealed to the bottom of the micro water pump, a second water guide pipe sealed to the top of the micro water pump, a circuit board, a cooling box, a heating box, and a steam nozzle fixed to the inner wall of the outer shell, a SCR fixed to one side of the circuit board, and a heating wire fixed to the inner wall of the heating box.

[0007] Furthermore, the top end of the second water guide pipe is sealed to the bottom of the cooling box, one side of the cooling box is attached to the side of the silicon controlled rectifier, and the top of the cooling box is sealed to the top.

[0008] Furthermore, the other end of the third water pipe is sealed and connected to one side of the heating box. Inside the outer shell, a partition layer is fixed in the middle of the cooling box and the heating box. The partition layer is double-layered and filled with heat insulation cotton in the middle.

[0009] Furthermore, a one-way valve is provided at one end of the third water guide pipe. The one-way valve is located on the side of the partition layer near the heating box. The third water guide pipe is installed through the partition layer. A connecting ring is fixed inside the one-way valve. A flow baffle is hinged to the connecting ring on the side near the heating box.

[0010] Furthermore, a control switch is fixed above the middle of one side of the outer wall of the grip, and the control switch is electrically connected to the micro water pump, circuit board, heating wire and steam nozzle.

[0011] Furthermore, a water bottle is provided on the top of the base, and one side of the bottom of the water bottle is snapped into the bottom of the handle. A water inlet pipe is fixed through the top of one side of the water bottle, and a sealing plug is provided on the outer wall of the water inlet pipe. A through hole is provided through the top of the water bottle, and the first water guide pipe passes through the inside of the through hole.

[0012] Furthermore, one side of the steam nozzle is fitted to the air outlet plate, and the top of the other side of the steam nozzle is sealed with a connecting pipe, the other end of which is connected to the top of the heating box.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This application utilizes a micro water pump to draw water from the kettle through the first water pipe and then into the cooling box through the second water pipe. The cooling box is made of stainless steel, which conducts heat well and prevents rusting. After the water passes through the cooling box, the overall temperature of the cooling box is low. The cooling box absorbs the heat generated by the operation of the silicon controlled rectifier. The micro water pump works in conjunction with the device to keep the water inside the cooling box circulating, so that the cooling box is always kept at a low temperature, thereby achieving a better heat dissipation effect through reasonable layout.

[0014] 2. This application isolates the cooling box, the thyristor, and the heating box through a partition layer to prevent the heat generated by the heating box from affecting the thyristor. When the water in the third water pipe flows through the one-way valve, the baffle plate lifts up, and the water that has absorbed heat enters the heating box directly. When the water inside the heating box is about to enter the third water pipe, the baffle plate is in contact with the connecting ring to prevent the backflow of water and the high temperature water from damaging the thyristor, thereby achieving the effect of preventing damage to the internal thyristor.

[0019] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0020] This application discloses a handheld garment steamer with a silicon controlled rectifier (SCR) water-cooled heat dissipation integrated structure, including a base 1, a handle 2 fixed to one side of the top of the base 1, an outer shell 4 fixed through the top of the handle 2, an air vent plate 8 fixed to one end of the outer shell 4, a micro water pump 10 fixed in the middle of the inner wall of the handle 2, a first water guide pipe 9 sealed to the bottom of the micro water pump 10, a second water guide pipe 11 sealed to the top of the micro water pump 10, a circuit board 12, a cooling box 14, a heating box 18 and a steam nozzle 20 fixed to the inner wall of the outer shell 4, a silicon controlled rectifier (SCR) body 13 fixed to one side of the circuit board 12, and a heating wire 19 fixed to the inner wall of the heating box 18.

[0021] Reference Appendix Figure 2 The top of the second water pipe 11 is sealed to the bottom of the cooling box 14. One side of the cooling box 14 is attached to the side of the thyristor 13. The top of the cooling box 14 is sealed to the third water pipe 15. Water is drawn from the water tank 5 through the first water pipe 9 by the operation of the micro water pump 10, and then flows into the cooling box 14 through the second water pipe 11. The cooling box 14 is made of stainless steel, which can conduct heat well and prevent rusting. After the water passes through the cooling box 14, the overall temperature of the cooling box 14 is low. The cooling box 14 absorbs the heat generated by the operation of the thyristor 13. The micro water pump 10 works together to keep the water inside the cooling box 14 circulating, so that the cooling box 14 is always kept at a low temperature.

[0022] Reference Appendix Figure 2 The other end of the third water pipe 15 is sealed and connected to one side of the heating box 18. Inside the outer shell 4, a partition layer 17 is fixed in the middle of the cooling box 14 and the heating box 18. The partition layer 17 is double-layered and filled with heat insulation cotton in the middle. The water that has absorbed heat inside the cooling box 14 continues to flow and enters the heating box 18 through the third water pipe 15. The partition layer 17 isolates the cooling box 14, the silicon controlled rectifier 13 and the heating box 18, preventing the heat generated by the heating box 18 from affecting the silicon controlled rectifier 13.

[0023] Reference Appendix Figure 2 and 4 The third water pipe 15 is equipped with a one-way valve 16 at one end. The one-way valve 16 is located on the side of the partition layer 17 near the heating box 18. The third water pipe 15 passes through the partition layer 17. A connecting ring 161 is fixed inside the one-way valve 16. A baffle plate 162 is hinged to the side of the connecting ring 161 near the heating box 18. When the water flows through the one-way valve 16 in the third water pipe 15, the baffle plate 162 is raised, and the water that has absorbed heat directly enters the heating box 18. When the water inside the heating box 18 is about to enter the third water pipe 15, the baffle plate 162 is in contact with the connecting ring 161 to prevent the water from flowing backward.

[0024] Reference Appendix Figure 1The handle 2 has a control switch 3 fixed on the upper middle part of one side of the outer wall. The control switch 3 is electrically connected to the micro water pump 10, circuit board 12, heating wire 19 and steam nozzle 20. When in use, the micro water pump 10, heating wire 19 and steam nozzle 20 are activated by pressing the control switch 3.

[0025] Reference Appendix Figure 3 The base 1 has a water bottle 5 on top. The bottom of the water bottle 5 is snapped into the bottom of the handle 2. A water inlet pipe 7 is fixed through the top of one side of the water bottle 5. A sealing plug is provided on the outer wall of the water inlet pipe 7. A through hole 6 is opened through the top of the water bottle 5. A first water guide pipe 9 passes through the through hole 6. When in use, the first water guide pipe 9 is inserted into the water bottle 5 through the through hole 6. Then the water bottle 5 is snapped into the handle 2. After the water in the water bottle 5 is used up, water can be added directly into the water bottle 5 through the water inlet pipe 7.

[0026] Reference Appendix Figure 2 One side of the steam nozzle 20 is fitted with the air outlet plate 8, and the other side of the steam nozzle 20 is sealed with a connecting pipe 21. The other end of the connecting pipe 21 is connected to the top of the heating box 18. The water inside the heating box 18 is heated by the operation of the heating wire 19. The heated water vapor enters the steam nozzle 20 from the connecting pipe 21 and is then ejected from the air outlet plate 8.

[0027] The workflow of this utility model is as follows: First, insert the first water pipe 9 through the through hole 6 into the kettle 5, then attach the kettle 5 to the handle 2. After the water in the kettle 5 is used up, simply add water directly into the kettle 5 through the inlet pipe 7. Pressing the control switch 3 activates the micro water pump 10, heating wire 19, and steam nozzle 20, energizing the circuit board 12. The micro water pump 10 draws water from the kettle 5 through the first water pipe 9, then flows into the cooling box 14 through the second water pipe 11. The cooling box 14 is made of stainless steel, which provides good heat conduction and prevents rust. The water passes through the cooling box 14, resulting in a lower overall temperature. The cooling box 14 absorbs the heat generated by the silicon controlled rectifier 13. The device operates via the micro water pump 10. Working together, the water inside the cooling tank 14 is kept circulating, keeping the cooling tank 14 at a low temperature. The heating wire 19 heats the water inside the heating tank 18. The heated water vapor enters the steam nozzle 20 through the connecting pipe 21 and is then ejected from the steam outlet plate 8. The partition layer 17 isolates the cooling tank 14, the silicon controlled rectifier 13 and the heating tank 18 to prevent the heat generated by the heating tank 18 from affecting the silicon controlled rectifier 13. When the water in the third water pipe 15 flows through the one-way valve 16, the baffle plate 162 is raised, and the water that has absorbed heat directly enters the heating tank 18. When the water inside the heating tank 18 is about to enter the third water pipe 15, the baffle plate 162 is in contact with the connecting ring 161 to prevent the water from flowing backward.
