It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate structural elements relevant to the present invention and not the entire structural structure.

[0104] Example 1

[0105] like Figure 1 As shown, this embodiment provides a heating system comprising a main channel 2000 and an output assembly 3000. A water tank 201, a pump 202, and a heater 203 are sequentially disposed on the main channel 2000. The output assembly 3000 is connected to the output end of the heater 203. When this heating system is used in an ironing machine, the pump 202 can drive water from the water tank 201 into the heater 203. The water forms hot steam in the heater 203, which is then ejected from the output assembly 3000, thereby ironing clothing.

[0106] The power of the heater 203 is variable, and different power levels can be selected. For example, the heater 203 has two power levels. When the heater 203 is in the first level, the power of the heater 203 is 1400W, which is suitable for ironing silk. When the heater 203 is in the second level, the power of the heater 203 is 2200W, which is suitable for ironing thick fabrics.

[0107] like Figure 1 As shown, the heating system also includes a cleaning branch 4000, a switching component 1000 and a controller. The outlet of the cleaning branch 4000 is connected to the water tank 201, and the switching component 1000 is respectively connected to the outlet of the main channel 2000, the inlet of the output component 3000 and the inlet of the cleaning branch 4000. The controller is electrically connected to the switching component 1000 and the pump 202, respectively. The controller is used to control the switching component 1000 to connect the main channel 2000 with the cleaning branch 4000, and to disconnect the main channel 2000 from the output component 3000. The controller also controls the operation of the pump 202. The pump 202 drives the cleaning branch 4000 and the main channel 2000 to form a liquid flushing loop within the loop to clean the loop pipe and components on the loop (such as the heating body 203). It can realize self-cleaning of the loop pipe and components on the loop, effectively remove scale in the heating system, improve the service life of the heating system, and improve the working efficiency of the heating system. The heating system in this embodiment can be applied to an ironing machine, thereby improving the service life and working efficiency of the ironing machine.

[0108] like Figure 9 As shown, the heating body 203 includes a substrate 2031 and a thick film heating body 2032. A groove 20321 is provided on the thick film heating body 2032. The thick film heating body 2032 covers one side of the substrate 2031. The groove 20321 cooperates with the substrate 2031 to form a flow channel. The flow channel includes an inlet and an outlet. The inlet is connected to the pump 202, and the outlet is connected to the switching component 1000. The heating body 203 can heat the fluid in the main channel 2000, so that the fluid in the main channel 2000 is converted into water vapor, thereby realizing the ironing effect of the ironing machine. The thick film heating body 2032 refers to: using screen printing technology to print insulating media, resistors, conductors, protective glaze and other materials on the substrate, and sintering them at high temperature. The thick film heating body 2032 has high strength, high heating efficiency, long life, safety, environmental protection and flexible use, and can realize the rapid formation of water vapor from the fluid. As a preferred solution, such as Figure 9 As shown, the flow channel is arranged in a spiral shape, which can increase the length of the flow channel in a limited area, thereby achieving a better heating effect on the fluid in the flow channel. As a preferred solution, Figure 9As shown, the flow channel is folded in half to form a folded body, one end of the folded body is the inlet and outlet, and the folded body is arranged in a spiral shape with the other end of the folded body as the center. The inlet and outlet are located on the outside of the folded body as a whole. Since the inlet and outlet are both located on the outside of the folded body as a whole, it is convenient for the operator to connect the inlet and outlet to the corresponding flow channel. As a preferred solution, Figure 9 As shown, the inlet and outlet are spaced apart to avoid the operator from mistakenly plugging the inlet and outlet into the corresponding pipeline.

[0109] As a preferred solution, Figure 1 As shown, the main channel 2000 also includes a third temperature detection module 206 electrically connected to the controller. The third temperature detection module 206 is provided at the outlet of the heating element 203. The controller is preset with a third preset temperature. If the temperature value detected by the third temperature detection module 206 exceeds the third preset temperature, the controller controls the pump 202 to increase its own power; if the temperature value detected by the third temperature detection module 206 is lower than the third preset temperature, the controller controls the pump 202 to reduce its own power. The pump 202 can automatically adjust the flow rate according to the temperature detected by the third temperature detection module 206, avoiding the waste of energy caused by the pump 202 always being too high in power, improving the energy utilization rate of the pump 202, and ensuring the steam effect. For example, the third preset temperature can be 120 degrees. If the temperature detected by the third temperature detection module 206 is greater than 120 degrees, the flow rate of the pump 202 is increased; if the temperature detected by the third temperature detection module 206 is lower than 120 degrees, the flow rate of the pump 202 is reduced. Through this temperature control, it can be measured that the temperature at the location of the third temperature detection module 206 is maintained at around 120 degrees. Specifically, the third temperature detection module 206 may be an NTC thermistor, which can achieve accurate and rapid temperature detection.

[0110] As a preferred embodiment, a fourth preset temperature is preset within the controller. When the temperature detected by the third temperature detection module 206 exceeds the fourth preset temperature, the controller controls the pump 202 to operate. Only when the temperature of the heating element 203 reaches a certain temperature can the liquid entering the heating element 203 be vaporized, thereby enabling the heating element 203 to effectively vaporize the liquid in the main channel 2000. For example, the fourth preset temperature can be between 200°C and 220°C.

[0111] As a preferred solution, Figure 1As shown, the main channel 2000 further includes a fourth temperature detection module 207. The fourth temperature detection module 207 and the heater 203 are electrically connected to the controller, and are disposed at the entrance of the heater 203. A fifth preset temperature is preset in the controller. When the temperature detected by the fourth temperature detection module 207 exceeds the fifth preset temperature, the controller controls the heater 203 to stop working. This is used to stop the heater 203 from working when the temperature of the heater 203 is too high to protect the heater 203. For example, the fifth preset temperature can be 400 degrees.

[0112] As a preferred solution, Figure 1 As shown, a flow detection module 205 is also provided on the main channel 2000 , and the flow detection module 205 can detect the flow of the main channel 2000 .

[0113] like Figure 1 As shown, the water tank 201 includes a water tank body 2011 and a filter assembly 2012. The water tank body 2011 is connected to the outlet of the cleaning branch 4000. The filter assembly 2012 is arranged inside the water tank body 2011. The inlet of the pump 202 is connected to the filter assembly 2012. The dirty liquid recovered from the circuit can be filtered by the filter assembly 2012 and then re-enter the main channel 2000 and the output assembly 3000, which can improve the utilization rate of the liquid in the water tank 201, reduce the frequency of the operator constantly replacing the liquid in the water tank 201, and simplify the operating process.

[0114] As a preferred solution, Figure 1 As shown, the main channel 2000 also includes a connecting pipe 204, one end of the connecting pipe 204 is connected to the pump 202, and the other end of the connecting pipe 204 is connected to the filter assembly 2012. The outlet of the cleaning branch 4000 is connected to the bottom of the water tank body 2011. The recovered wastewater gradually rises upward from the bottom of the water tank body 2011, which can avoid the noise generated by the wastewater falling from a high place, so that the heating system maintains a silent effect during the self-cleaning process.

[0115] The filter assembly 2012 is disposed at the bottom of the water tank body 2011, and the end of the connecting pipe 204 away from the pump 202 is connected to the bottom of the filter assembly 2012. Even if the liquid level in the water tank body 2011 is low, the liquid in the water tank body 2011 can still enter the connecting pipe 204, thereby improving the utilization rate of the liquid in the water tank body 2011. As a preferred solution, Figure 1 As shown, the filter assembly 2012 is detachably connected to the water tank body 2011, which facilitates the rapid disassembly and replacement of the filter assembly 2012.

[0116] As a preferred solution, Figure 1As shown, filter assembly 2012 includes a filter screen 20121 and a filter element 20122. Filter element 20122 is disposed within filter screen 20121, which is connected to the interior of water tank body 2011. The provision of filter screen 20121 allows for the filtration of larger impurities (such as large particles and bulky objects), while the provision of filter element 20122 allows for the filtration of smaller impurities. This allows for cleaner liquid to enter the subsequent heating process, preventing scale buildup within the heating system and improving the service life and efficiency of the heating system. Specifically, filter element 20122 in this embodiment is made of FOF (FoF) scale inhibitor. FOF scale inhibitor directly participates in and interferes with the formation of scale nuclei in the initial stages of scale growth, i.e., the initial stages of scale nucleation. This ion-based inhibitor causes the nuclei to distort and abort during their developmental stages, thus preventing scale crystal formation.

[0117] As a preferred solution, Figure 1 As shown, in order to avoid the dry burning phenomenon of the heating system, a liquid level detection component 2013 is also provided inside the water tank body 2011. When the water level in the water tank body 2011 is too low, the heating system will stop working to avoid the dry burning phenomenon of the heating system, ensure the normal use of each component, and increase the service life of the heating system.

[0118] Combine Figure 1 The specific structure of the output component 3000 is described as follows: Figure 1 As shown, the output component 3000 includes a switching module 301, a first output module 302, and a second output module 303. The inlet of the switching module 301 is connected to the switching component 1000, and the outlet of the switching module 301 is connected to the first output module 302 and the second output module 303 respectively. The switching module 301 is electrically connected to the controller, which controls the switching module 301 to operate the first output module 302 and / or the second output module 303, thereby adapting to different types of clothing and achieving better ironing effects for different clothing. When ironing a larger area of clothing, the first output module 302 and the second output module 303 can be turned on at the same time. When ironing a smaller area of clothing, only the first output module 302 or the second output module 303 can be turned on.

[0119] The first output module 302 includes a first temperature detection module. The first output module 302 has at least two settings, each with a first preset temperature stored in the controller. When the temperature detected by the first temperature detection module exceeds the first preset temperature corresponding to the setting, the controller controls the first output module 302 to stop operating, thereby preventing overheating and ensuring the steam volume and temperature corresponding to the setting. For example, the first output module 302 includes a first, second, and third setting. The first setting corresponds to a preset temperature of 80°C, the second setting to 100°C, and the third setting to 120°C. When the operator activates the first setting, if the temperature detected by the first temperature detection module exceeds 80°C, the controller controls the first output module 302 to stop operating, thereby ensuring that the steam volume and temperature of the first output module 302 match the clothing corresponding to the setting. For example, the first setting corresponds to silk, the second setting to cotton, and the third setting to thick fabric.

[0120] The second output module 303 includes a second temperature detection module. The second output module 303 has at least two gears, each with a second preset temperature stored in the controller. When the temperature detected by the second temperature detection module exceeds the second preset temperature corresponding to the gear, the controller controls the second output module 303 to stop operating, thereby preventing the second output module 303 from overheating and ensuring the steam pressure and steam temperature corresponding to the gear. For example, the second output module 303 includes a first gear, a second gear, and a third gear. The first gear corresponds to a preset temperature of 80 degrees Celsius, the second gear corresponds to a preset temperature of 100 degrees Celsius, and the third gear corresponds to a preset temperature of 120 degrees Celsius. When the operator activates the first gear, if the temperature detected by the first temperature detection module exceeds 80 degrees Celsius, the controller controls the second output module 303 to stop operating, thereby ensuring that the steam volume, steam pressure, and steam temperature of the second output module 303 are matched to the clothing corresponding to the gear. For example, the first gear is suitable for silk, the second gear is suitable for cotton, and the third gear is suitable for thick fabrics.

[0121] Since the heating system has a long distance, part of the hot steam emitted from the heating body 203 will condense into liquid, causing the hot steam ejected from the first output module 302 or the second output module 303 to be mixed with liquid, resulting in large water marks on the ironed clothes.

[0122] In order to solve the above problems, Figure 2 and Figure 3As shown, the first output module 302 includes a first main body 3021 and a first heating structure 3022. A first temporary storage chamber 3021 is formed inside the first main body 3021. The first main body 3021 is connected to the outlet of the switching module 301. The first heating structure 3022 is arranged on the first main body 3021 to heat the vapor-liquid mixture in the first temporary storage chamber 30211, and can heat the liquid of the vapor-liquid mixture into dry steam. A first exhaust hole 30221 connected to the first temporary storage chamber 30211 is provided on the first heating structure 3022. The dry steam is discharged from the first exhaust hole 30221, which can effectively prevent water marks on clothes.

[0123] As a preferred solution, a first labyrinth flow channel is formed inside the first temporary storage chamber 30211, the inlet of the first labyrinth flow channel is connected to the inlet of the first main body 3021, and the outlet of the first labyrinth flow channel is connected to the first exhaust hole 30221. The first labyrinth flow channel can effectively extend the flow path of the vapor-liquid mixture, increase the heating time of the vapor-liquid mixture by the first heating structure 3022, and make the liquid in the vapor-liquid mixture evaporate into gas more fully, thereby improving the ironing effect on clothes.

[0124] As a preferred solution, Figure 4 As shown, the second output module 303 includes a second main body 3031 and a second heating structure 3032. A second temporary storage chamber is formed inside the second main body 3031. The second main body 3031 is connected to the outlet of the switching module 301. The second heating structure 3032 is arranged on the second main body 3031 to heat the vapor-liquid mixture in the second temporary storage chamber, and can heat the liquid of the vapor-liquid mixture into dry steam. A second exhaust hole 30321 connected to the second temporary storage chamber is provided on the second heating structure 3032. The dry steam is discharged from the second exhaust hole 30321, which can effectively prevent water marks on clothes.

[0125] As a preferred embodiment, a second labyrinth flow channel is formed inside the second temporary storage chamber, the inlet of the second labyrinth flow channel is connected to the inlet of the second main body 3031, and the outlet of the second labyrinth flow channel is connected to the second exhaust hole 30321. The second labyrinth flow channel can effectively extend the flow path of the vapor-liquid mixture, increase the heating time of the vapor-liquid mixture and the second heating structure 3032, and make the liquid in the vapor-liquid mixture evaporate into gas more fully, thereby improving the ironing effect on clothes.

[0126] like Figure 2 and Figure 4As shown, the first heating structure 3022 has only one second exhaust hole 30221, while the second output module 303 has multiple second exhaust holes 30321. The total area of the multiple second exhaust holes 30321 is larger than that of the first exhaust hole 30221. The first exhaust hole 30221 can eject high-pressure, concentrated, and large amounts of steam, which is suitable for thicker or harder clothing. The second exhaust holes 30321 evenly eject steam from multiple dispersed openings, which is suitable for thinner or softer clothing.

[0127] As a preferred solution, Figure 1 As shown, the heating system further includes a pressure relief branch 5000, on which a pressure relief valve 501 is provided. One end of the pressure relief branch 5000 is connected to the outlet of the pump 202, and the other end of the pressure relief branch 5000 is connected to the cleaning branch 4000. When some locations in the heating system are clogged due to scale, the liquid pressure at the pressure relief valve 501 is relatively high. When the liquid pressure at the pressure relief valve 501 exceeds the preset pressure of the pressure relief valve 501, the pressure relief valve 501 will open, and the liquid will enter the water tank 201 through the cleaning branch 4000, thereby preventing the heating system from exploding or leaking, thereby ensuring the safe and normal use of the ironing machine using the heating system.

[0128] Combine Figure 1 The structure of the switching component 1000 is described as follows. Figure 1 As shown, the switching assembly 1000 includes a vapor-liquid separation device 100, a first valve 200, and a second valve 300. The vapor-liquid separation device 100 is provided with a vapor inlet 1121, a drainage structure 125, and an output pipe 2. The inlet of the cleaning branch 4000 is connected to the drainage structure 125 via the first valve 200, and the inlet of the output assembly 3000 is connected to the output pipe 2 via the second valve 300. The first valve 200 and the second valve 300 are both electrically connected to a controller. The controller controls the first valve 200 to be open, the second valve 300 to be closed, and the pump 202 to operate, so that the heating system can clean the heating system channels. The controller controls the first valve 200 to be closed, the second valve 300 to be open, and the pump 202 to operate, so that the output assembly 3000 can discharge hot steam or hot water.

[0129] like Figure 1 and Figure 5As shown, the vapor-liquid separation device 100 provided in this embodiment also includes a main body 1, the main body 1 includes a separation structure 11 and a liquid processing mechanism located below the separation structure 11, a vapor inlet 1121 is provided on the separation structure 11, the output pipe 2 is connected to the separation structure 11, the output pipe 2 is connected to the interior of the separation structure 11, the drainage structure 125 is connected to the liquid processing mechanism at one end away from the first valve 200, the steam enters the vapor-liquid separation device 100 from the vapor inlet 1121, the vapor in the steam is discharged through the outlet 222, and the liquid in the steam enters the liquid processing mechanism.

[0130] As a preferred solution, Figure 5 As shown, the output pipe 2 includes an air inlet 2131 and an air outlet 222. The air outlet 222 is connected to the outside of the separation structure 11. The air inlet 2131 is located inside the separation structure 11 and below the gas inlet 1121. Steam enters the separation structure 11 at high speed from the gas inlet 1121. The high-speed steam forms a high-speed cyclonic steam flow in the separation structure 11. Water droplets entrained in the cyclonic steam flow are separated from the water vapor under the centrifugal force of the high-speed cyclonic steam flow. The separated water droplets are thrown onto the inner wall of the separation structure 11. Under the action of gravity, the water droplets fall in a spiral shape along the inner wall of the separation structure 11. The steam separated from the water droplets enters the air inlet 2131 of the output pipe 2 and is discharged from the air outlet 222 of the output pipe 2. Ultimately, the vapor-liquid separation device 100 achieves a good separation effect on the gas and liquid in the steam.

[0131] As a preferred solution, Figure 5 As shown, the vertical distance between the air inlet 2131 and the gas inlet 1121 is not less than 10 mm, which can achieve a sufficient cyclonic effect on the gas-liquid mixture and improve the separation effect of the gas and liquid. However, if the vertical distance between the air inlet 2131 and the gas inlet 1121 is too long, the overall length of the gas-liquid separation device 100 will be too long. In this embodiment, the vertical distance between the air inlet 2131 and the gas inlet 1121 is preferably 15 mm to 20 mm. Within this range, it can not only ensure the sufficient separation effect of the gas-liquid mixture, but also ensure that the length of the gas-liquid separation device 100 is moderate, making it convenient for the gas-liquid separation device 100 to be suitable for scenes with smaller spaces and convenient for storage and transportation of the gas-liquid separation device 100. Among them, the main body 1 and the output pipe 2 can be split, and the output pipe 2 is plugged into the main body 1. By adjusting the different lengths of the output pipe 2, it is suitable for different application scenarios. The main body 1 and the output pipe 2 can also be integrally molded by injection molding, which can effectively improve the assembly efficiency of the gas-liquid separation device 100.

[0132] like Figure 5As shown, the body 1 also includes a liquid treatment mechanism located below the separation mechanism 11. The water droplets separated by the separation mechanism 11 fall from the inner wall of the structure 11 in a spiral shape and eventually fall into the liquid treatment mechanism. The liquid stored in the liquid treatment mechanism can be discharged or reused. Specifically, as Figure 5 As shown, the liquid processing mechanism is a liquid storage structure 12, and the liquid storage mechanism 12 can store the separated liquid.

[0133] The vapor-liquid separation device 100 provided in this embodiment can be used in the steam injection system of an ironing machine. The steam injection system includes a steam generating device and a steam injection head. The steam generating device can generate steam. The outlet of the steam generating device is connected to the steam inlet 1121 of the vapor-liquid separation device 100. The air outlet of the output pipe 2 is connected to the air inlet end of the steam injection head. Through the vapor-liquid separation effect of the vapor-liquid separation device 100, the liquid in the steam generated by the steam generating device can be stored in the liquid storage structure 12. The dried steam enters the steam injection head from the output pipe 2 and is ejected from the steam injection head. This can prevent the steam injection head from spraying water droplets, avoid water marks on clothes, and ensure that the clothes can be worn normally.

[0134] Combine Figure 5 The structure of the separation structure 11 is described as follows. Figure 5 As shown, the separation structure 11 includes a cover 111 and a separation tube 112. The cover 111 includes a blocking portion 1111 and a first connecting portion 1112 connected to the blocking portion 1111. The output pipe 2 is connected to the blocking portion 1111. One end of the separation tube 112 is connected to the first connecting portion 1112, and the other end of the separation tube 112 is connected to the liquid storage structure 12. During the rising process of the steam after the vapor-liquid separation, condensed water is generated in the blocking portion 1111 due to heat loss. The condensed water falls off under the action of gravity and re-participates in the cyclonic separation motion driven by the high-speed cyclonic steam flow. The separated water droplets are finally gathered in the liquid storage structure 12.

[0135] If the distance between the air inlet 2131 and the blocking portion 1111 is relatively close, the condensed water at the blocking portion 1111 will be directly sucked into the air inlet 2131 due to the negative pressure at the air inlet 2131, resulting in poor gas-liquid separation effect. Figure 5 As shown, the air inlet 2131 is lower than the blocking part 1111, which increases the height difference and distance of the condensed water droplets on the blocking part 1111 entering the air inlet 2131, and can effectively prevent the condensed water droplets on the blocking part 1111 from entering the air inlet 2131, thereby ensuring the vapor-liquid separation effect of the vapor-liquid separation device 100.

[0136] Specifically, if Figure 5As shown, the greater the vertical distance between the air inlet 2131 and the blocking portion 1111, the better, which can prevent condensed water droplets on the blocking portion 1111 from entering the air inlet 2131. Preferably, the vertical distance between the air inlet 2131 and the blocking portion 1111 is between 5 mm and 30 mm, which can prevent the length of the gas-liquid separation device 100 from being too long, and can make the gas-liquid separation device 100 of a moderate length suitable for use in environments with limited space.

[0137] Since there are some impurities in the gas-liquid mixture to be separated, the gas-liquid separation device 100 may form impurities accumulation in the output pipe 2 during long-term use, resulting in blockage of the channel of the output pipe 2, making it difficult for the separated gas to be discharged from the output pipe 2. In order to solve the above problem, as Figure 5 As shown, the first connection portion 1112 of this embodiment is detachably connected to the separation pipe 112, and the operator can clean the cover 111 and the output pipe 2 removed from the separation pipe 112, thereby achieving a better exhaust effect of the output pipe 2. Figure 5 As shown, the longitudinal cross-section of the inner wall of the separator tube 112 is formed of two parallel straight lines, resulting in a simple structure. This facilitates demolding during injection molding of the separator tube 112, thereby improving the molding efficiency of the separator tube 112. Furthermore, the separator tube 112 has a uniform thickness along the vertical direction, which prevents excessive stress on a localized portion of the separator tube 112 due to uneven thickness, thereby ensuring a longer life for the separator tube 112.

[0138] Specifically, if Figure 5 As shown, the first connecting portion 1112 of this embodiment is threadedly connected to the separation tube 112. The operator can remove the first connecting portion 1112 from the separation tube 112 by simply rotating the first connecting portion 1112, which is simple, convenient, and easy to operate. Of course, in other embodiments, the first connecting portion 1112 and the separation tube 112 can also be connected by screws, pins, buckles, etc., which can also achieve a detachable connection between the first connecting portion 1112 and the separation tube 112.

[0139] Specifically, if Figure 5As shown, the first connecting portion 1112 of this embodiment includes a first connecting ring 11121 and a second connecting ring 11122, each connected to the blocking portion 1111. The first connecting ring 11121 and the second connecting ring 11122 are coaxial and spaced apart. One end of the separator tube 112 is inserted between the first connecting ring 11121 and the second connecting ring 11122, and at least one of the first connecting ring 11121 and the second connecting ring 11122 is threadedly connected to the separator tube 112. The gap between the first connecting ring 11121 and the second connecting ring 11122 enables rapid pre-assembly and positioning of the separator tube 112 and the first connecting portion 1112, thereby improving the operator's ability to accurately position the first connecting portion 1112 and the separator tube 112. In addition, by providing a first connecting ring 11121 or a second connecting ring 11122 without threads, a guiding function can be achieved for the first connecting part 1112 during the rotation process, thereby preventing the operator from applying a deflected force to the first connecting part 1112, which may cause the first connecting part 1112 and the separation tube 112 to be unable to be tightened.

[0140] In order to ensure good sealing performance of the gas-liquid separation device 100 and smooth progress of the cyclone separation movement, Figure 5 As shown, the cover 111 further includes a first sealing structure 113, which is located in the gap between the first connecting ring 11121 and the second connecting ring 11122, and between the end of the output pipe 2 and the blocking portion 1111. Specifically, in order to ensure that the first sealing structure 113 has a good sealing effect at various circumferential positions of the first connecting ring 11121 and the second connecting ring 11122, as shown in FIG. Figure 5 As shown, the first sealing structure 113 is a sealing ring, which is sleeved on the outer circumference of the first connecting ring 11121 to further improve the sealing effect of the cover body 111 and the separation tube 112 at the contact position.

[0141] The liquid stored in the liquid storage structure 12 will form a water vortex under the action of the cyclonic airflow. The edge of the water vortex will produce higher and larger water splashes. The splashing water may escape from the air inlet 2131 along the cyclonic airflow. In order to solve the above problem, Figure 5 As shown, an annular baffle 1122 is provided on the inner wall of the separation tube 112, and the annular baffle 1122 is used to prevent the liquid in the liquid storage structure 12 from splashing into the output tube 2. In other embodiments, the annular baffle 1122 can also be provided on the inner wall of the liquid storage structure 12 to also prevent the liquid in the liquid storage structure 12 from splashing into the output tube 2.

[0142] As a preferred solution, Figure 5As shown, one end of the annular baffle 1122 is connected to the inner wall of the separation tube 112, and the other end of the annular baffle 1122 extends toward the liquid storage structure 12. The annular baffle 1122 is inclined from top to bottom toward the center line of the main body 1, and the opening surrounded by the lower end of the annular baffle 1122 is smaller, which can achieve the following effects: 1) It can weaken the steam flow intensity of the vortex entering the liquid storage structure 12; 2) It can effectively weaken the rotational motion of the water vortex, reduce the water level height at the edge when the liquid rotates, and reduce the risk of water splashes escaping from the air inlet 2131. The flange 213 can block the water splashes at the edge; 3) The annular baffle 1122 can gather the water droplets above it to better enter the liquid storage structure 12. Specifically, the cross-sectional area of the hole formed by the other end of the annular baffle 1122 is 1 / 9 to 1 / 3 of the cross-sectional area of the internal space of the separation tube 112. While ensuring that the separation tube 112 can flow into the liquid storage structure 12, it can also prevent water splashes in the liquid storage structure 12 from entering the air inlet 2131, among which 1 / 4 is preferred.

[0143] As a preferred solution, the distance from the center of the gas inlet 1121 to the lower end of the annular baffle 1122 along the vertical direction is a first distance L1, and the distance from the center of the gas inlet 1121 to the air inlet 2131 along the vertical direction is a second distance L2, and L2 / L1 is 2 / 7 to 1 / 2, which can achieve sufficient cyclone of the gas-liquid mixture and ensure that the length of the gas-liquid separation device 100 is moderate.

[0144] Combine Figure 5 The structure of the liquid storage structure 12 is described as follows. Figure 5 As shown, the liquid storage structure 12 includes a liquid storage tube 121, a second connecting part 122 and a buffer part 123. The second connecting part 122 and the buffer part 123 are respectively located at the two ends of the liquid storage tube 121. The second connecting part 122 is connected to the end of the separation tube 112 away from the cover body 111. The buffer part 123 is a hemispherical structure. The hemispherical structure of the buffer part 123 makes the rotation of the liquid smoother, reduces the generation of splashes, and further avoids splashing water from overflowing from the air outlet 222.

[0145] like Figure 5As shown, the separation tube 12 also includes a drainage structure 125 connected to the separation tube 12. When the water volume of the liquid storage structure 12 reaches a certain level, the stored liquid will be discharged along the drainage structure 125 to avoid affecting the vapor-liquid separation effect of the vapor-liquid separation device 100. As a preferred embodiment, in order to avoid this, the drainage structure 125 also includes a sealing plug. The sealing plug is blocked at the outlet of the drainage structure 125, which can prevent the liquid in the liquid storage structure 12 from flowing out freely and causing a short circuit in adjacent electrical components, thereby ensuring the safety of the use of the vapor-liquid separation device 100 and the personal safety of the user. In addition, a solenoid valve can be set on the drainage structure 125 or on the pipeline connected to the drainage structure 125, and a liquid level detection device can be set on the liquid storage tube 121. When the liquid level detection device detects that the liquid in the liquid storage tube 121 exceeds a preset height (maximum height), the liquid level detection device controls the solenoid valve to open, and the drainage structure 125 discharges the liquid in the liquid storage tube 121, ensuring a good vapor-liquid separation effect of the vapor-liquid separation device 100.

[0146] When the gas-liquid separation device 100 is used in an ironing machine, the liquid used in the ironing machine is usually tap water from a faucet. Since scale will form in tap water after long-term use, the drainage structure 125 is easily clogged by scale, resulting in clogging of the drainage structure 125. In order to solve the above problem, Figure 5 As shown, the second connecting portion 122 is detachably connected to the end of the separation tube 112 away from the cover 111, allowing the liquid storage structure 12 and the separation tube 112 to be separated and cleaned separately, ensuring relatively smooth drainage of the liquid discharge structure 125. Specifically, the second connecting portion 122 is threadedly connected to the end of the separation tube 112 away from the cover 111, allowing the operator to remove the liquid storage structure 12 from the separation tube 112 with a simple operation, making it convenient for the operator to remove the liquid storage structure 12 from the separation tube 112 in a narrow space.

[0147] Specifically, if Figure 5As shown, the second connecting portion 122 includes a locking section 1221 and a connecting section 1222, one end of the connecting section 1222 away from the locking section 1221 is connected to the liquid storage tube 121, the locking section 1221 is arranged around the outer periphery of the liquid storage tube 121 and is spaced apart from the liquid storage tube 121, and the end of the separation tube 112 away from the cover body 111 is inserted into the gap between the locking section 1221 and the liquid storage tube 121 and is threadedly connected to the locking section 1221. When the operator rotates the liquid storage structure 12, the liquid storage tube 121 facing the locking section 1221 can guide the rotation of the liquid storage structure 12, avoiding the second connecting portion 122 and the separation tube 112 from being unable to be screwed into place due to uneven force applied by the operator, ensuring a good connection between the second connecting portion 122 and the separation tube 112, preventing the second connecting portion 122 and the separation tube 112 from loosening, and preventing the separator 100 from leaking during use.

[0148] As a preferred solution, Figure 5 As shown, the liquid storage structure 12 further includes a second sealing structure 124 , which is located between the end of the separation tube 112 away from the cover body 111 and the connecting section 1222 , and can further prevent the separator 100 from leaking during use.

[0149] like Figure 6 and Figure 7 As shown, the vapor-liquid separation device 100 also includes an input pipe 114, which is connected to the outer wall of the separation tube 112. An input pipe channel 1141 is opened on the input pipe 114, and one end of the input pipe channel 1141 is connected to the vapor inlet 1121, and the other end of the input pipe channel 1141 can be connected to the vapor-liquid mixture. The vapor-liquid mixture enters the vapor inlet 1121 through the input pipe channel 1141 and further enters the interior of the separation tube 112.

[0150] As a preferred solution, Figure 6 As shown, the separation structure 11 further includes a reinforcing rib 115 , and the input pipe 114 and the separation pipe 112 are connected via the reinforcing rib 115 . The reinforcing rib 115 can provide stable support for the input pipe 114 .

[0151] As a preferred solution, Figure 7As shown, the longitudinal cross-section of the input pipe channel 1141 includes an outer guide surface 11411 and an inner guide surface 11412. The inner guide surface 11412 is closer to the centerline of the body 1. The outer guide surface 11411 is tangent to the contour line of the cross-section of the inner wall of the separation tube 112, and the inner guide surface 11412 is parallel to the outer guide surface 11411. The vapor-liquid mixture entering through the input pipe channel 1141 can flow along the inner wall of the separation tube 112 into the interior of the separation tube 112, facilitating the formation of a cyclonic state for the incoming vapor-liquid mixture and improving the degree of vapor-liquid separation of the vapor-liquid mixture.

[0152] As a preferred embodiment, the diameter of input pipe channel 1141 gradually decreases from the free end to the gas inlet 1121. This increases the pressure of the vapor-liquid mixture upon entry into separation tube 112, improves the initial velocity of the vapor-liquid mixture upon entry, enhances the cyclonic effect of the vapor-liquid mixture, and further enhances the vapor-liquid separation effect. To prevent the vapor-liquid mixture from losing kinetic energy within input pipe 114 and ensure that the vapor-liquid mixture fully cyclones within separation tube 112, the length of input pipe channel 1141 is 1 / 2 to 1 / 3 the diameter of separation tube 112.

[0153] For ease of understanding, combined Figure 1 、 Figure 2 as well as Figure 4 The working process of the heating system is described as follows:

[0154] like Figure 1 As shown, after the entire device is started, the first heating structure 3022 or the second heating structure 3032 is powered on for low-power heating, and the heated body 203 also begins to preheat. When the temperature detected by the third temperature detection module 206 exceeds a fourth preset temperature, the controller controls the pump 202 to operate. Only when the temperature of the heated body 203 reaches a certain temperature can the liquid entering the heated body 203 be vaporized, so that the heated body 203 can effectively vaporize the liquid in the main channel 2000. For example, the fourth preset temperature can be 200 degrees to 220 degrees.

[0155] When the temperature detected by the fourth temperature detection module 207 exceeds the fifth preset temperature, the controller controls the heater 203 to stop working, so as to protect the heater 203 when the temperature of the heater 203 is too high. For example, the fifth preset temperature may be 400 degrees.

[0156] If the temperature value detected by the third temperature detection module 206 exceeds the third preset temperature, the controller controls the pump 202 to increase its own power; if the temperature value detected by the third temperature detection module 206 is lower than the third preset temperature, the controller controls the pump 202 to reduce its own power. The pump 202 can automatically adjust the flow rate according to the temperature detected by the third temperature detection module 206, thereby avoiding the waste of energy caused by the pump 202 always having too much power, improving the energy utilization rate of the pump 202, and ensuring the steam effect. For example, the third preset temperature can be 120 degrees. If the temperature detected by the third temperature detection module 206 is greater than 120 degrees, the flow rate of the pump 202 increases; if the temperature detected by the third temperature detection module 206 is less than 120 degrees, the flow rate of the pump 202 decreases. Through the above temperature control, it can be measured that the temperature at the location of the third temperature detection module 206 is maintained at around 120 degrees.

[0157] The controller controls the switching module 301 to activate the first output module 302 and / or the second output module 303, thereby adapting to different types of clothing and achieving better ironing effects for different clothing. When ironing a larger area of clothing, the first output module 302 and the second output module 303 can be activated simultaneously. When ironing a smaller area of clothing, only the first output module 302 or the second output module 303 can be activated.

[0158] A pressure switch 400 electrically connected to a controller is provided between the vapor-liquid separation device 100 and the second valve 300. The controller is configured with a preset pressure value. When the pressure detected by the pressure switch 400 exceeds the preset pressure value, the controller controls the second valve 300 to open and the first valve 100 to close, thereby enabling the output assembly 3000 to output steam. Furthermore, a pressure detection device is also provided between the vapor-liquid separation device 100 and the second valve 300. The pressure detection device is electrically connected to the controller. When the pressure detected by the pressure detection device exceeds the preset pressure value, the controller controls the heating element 203, the first heating structure 3022, and the second heating structure 3032 to stop operating, thereby preventing explosions in the heating system and ensuring safe operation of the heating system. Furthermore, since residual liquid in the heating element 203 can easily cause the output assembly 3000 to spray liquid, the controller controls the first valve 200 to open for 5 seconds and the second valve 300 to close for 5 seconds after each heating system operation. The hot steam generated by the heating element 203 is then used to squeeze the remaining liquid into the water tank 2011.

[0159] When the heating system needs to be descaled or cleaned, the controller controls the second valve 300 to close, the controller controls the first valve 200 to open, and the controller controls the pump 202 to start working, thereby achieving cleaning of the circuit by the circulating water.

[0160] Example 2

[0161] The output pipe 2 in the gas-liquid separation device 100 in Example 1 is a tube. Since the part of the output pipe 2 extending outside the main body 1 needs to be connected to the hoses of other components, the input end and the output end of the output pipe 2 are relatively small in size. The small-diameter air inlet 2131 will cause a large negative pressure at the air inlet 2131, which will cause water droplets at the air inlet 2131 to be easily sucked into the output pipe 2, resulting in poor gas-liquid separation effect of the gas-liquid mixer 100.

[0162] In order to solve the above problems, Figure 8 As shown, the output pipe 2 of the vapor-liquid separation device 100 of this embodiment includes a primary output pipe 21 and a secondary output pipe 22. The primary output pipe 21 is connected to the separation structure 11 and is located inside the separation structure 11. An air inlet 2131 is provided on the primary output pipe 21. The secondary output pipe 22 is connected to the separation structure 11 and partially extends into the primary output pipe 21. The air outlet 222 is provided on the secondary output pipe 22. An air inlet opening 221 is provided at the end of the secondary output pipe 22 extending into the primary output pipe 21. The air inlet 2131 is lower than the air inlet opening 221, and the diameter of the air inlet 2131 is larger than the diameter of the air outlet 222. Since the diameter of the air inlet 2131 is large, the negative pressure of the air inlet 2131 is low, and the air inlet 2131 is some distance away from the air outlet 222, it is difficult for water droplets near the air inlet 2131 to be sucked into the air inlet 2131, so it is difficult for water droplets to enter the secondary output pipe 22 and be discharged, which can further ensure that the gas-liquid separation effect of the gas-liquid separation device 100 is better.

[0163] Specifically, in order to effectively reduce the negative pressure of the air inlet 2131, in this embodiment, the diameter of the air inlet 2131 is preferably 1.5 to 4 times the diameter of the air outlet 222. Specifically, the diameter of the air inlet 2131 in this embodiment is 4.5 mm to 12 mm.

[0164] In order to further reduce the possibility of water droplets at the air inlet 2131 entering the air inlet opening 221, in this embodiment, the distance between the air inlet opening 221 and the air inlet 2131 is 2 / 3 to 5 / 6 of the length of the first-level output pipe 21. Since the air inlet opening 221 is far away from the air inlet 2131, even if some water droplets at the air inlet 2131 enter the first-level output pipe 21, the water droplets cannot reach the air inlet opening 221 due to their own gravity during the operation of the longer path. The possibility of water droplets at the air inlet 2131 entering the air inlet opening 221 can be further reduced, thereby ensuring a better gas-liquid separation effect of the gas-liquid separation device 100.

[0165] As a preferred solution, Figure 8As shown, the primary output pipe 21 includes a third connecting portion 211, a separation portion 212, and a flange 213. The third connecting portion 211 is connected to the separation structure 11, and one end of the separation portion 212 is connected to the third connecting portion 211. The flange 213 is provided at the end of the separation portion 212 away from the third connecting portion 211. The flange 213 is inclined from top to bottom in a direction away from the centerline of the body 1. The flange 213 can cause the water droplets separated by centrifugal motion to be thrown outward and downward, away from the air inlet 2131, making the air inlet 2131 drier and ensuring the vapor-liquid separation effect of the vapor-liquid separation device 100.

[0166] The distance between the center of the gas inlet 1121 and the upper end of the flange 213 in the vertical direction is a third distance L3, and the distance between the upper end of the flange 213 and the lower end of the flange 213 in the vertical direction is a fourth distance L4, where L4 / L3 is 1 / 8 to 1 / 20, which can ensure that the gas after sufficient centrifugal movement is discharged from the air inlet 2131 in a relatively dry state.

It should be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, which are merely illustrative of the principles of the present invention.
