Description

Technical Field

[0001] The present application relates to the technical field of steam generation, and in particular to a steam component and a steam generating device. Background Art

[0002] As people's living standards improve, handheld steam devices, such as steam irons, steam hot pots, etc., are increasingly used in people's lives. Various handheld steam devices can quickly heat liquid water and vaporize it into high-temperature steam to meet people's different life needs such as ironing or steaming.

[0003] In the related art, a handheld steam device is provided with a steam component for generating steam. The steam component generally includes a heating element, a steam chamber and a thermostat. The heat generated by the heating element can be transferred to the steam chamber. When the user turns on the handheld steam device, liquid water enters the steam chamber through the water drop point, and is then vaporized into high-temperature steam in the steam chamber by the heat generated by the heating element. Among them, most of the liquid water entering the steam chamber can be vaporized by the high temperature in the steam chamber at the water drop point to generate steam. Since most of the liquid water is vaporized at the water drop point of the steam chamber, it will absorb a large amount of heat near the water drop point in the steam chamber. When the thermostat detects that the temperature near the water drop point is low, when there is still heat in other areas to vaporize water, the thermostat will control the heating element to be powered on and heated, so that the temperature of the heating element near the water drop point reaches the preset temperature.

[0004] However, the related art may cause heat waste and low vaporization efficiency of liquid water at the water entry point. Utility Model Content

[0005] In view of the above problems, the embodiments of the present application provide a steam component and a steam generating device, which solve the problems of heat waste of the heating element and low water vaporization efficiency.

[0007] In a first aspect, an embodiment of the present application provides a steam component, comprising: a heating element, the heating element comprising a heat-insulating shell, a heating element and a heat-conducting water pipe, the heat-conducting water pipe being at least partially fitted to the heating element so that the heating element and the heat-conducting water pipe can exchange heat; the heat-insulating shell is arranged around the outer periphery of the heating element and the heat-conducting water pipe; a steam chamber is formed in the heat-insulating shell, one end of the heat-conducting water pipe is configured to be connected to a water source, and the other end of the heat-conducting water pipe is configured to communicate with the steam chamber so that liquid entering the steam chamber can be vaporized.

[0008] In the steam assembly provided by the embodiment of the present application, the heating element and the heat-conducting water pipe are arranged to be at least partially fitted, so that the liquid water flowing through the heat-conducting water pipe can be pre-heated with the heating element before entering the steam chamber inside the heat-insulating shell, so that in the process of heating to generate steam, the heat of various parts of the heating element can be evenly and fully absorbed by the flowing water, avoiding the waste of heat and effectively improving the utilization efficiency of heat. At the same time, the water is pre-heated before entering the steam chamber and has a higher temperature. After entering the steam chamber, it can be more quickly and fully vaporized at the water entry point, reducing the water that cannot be vaporized in other parts of the steam chamber, thereby improving the vaporization speed and conversion rate of the water.

[0009] In some embodiments, the contour shape of the heat conducting water pipe matches the contour shape of the heating element, and the heat conducting water pipe is disposed on at least one side of the heating element and is in contact with the heating element.

[0019] In some embodiments, the heat-insulating shell, the heating element and the hot water pipe are an integral die-cast structure.

[0020] With this arrangement, the heating element and the heat-conducting water pipe are die-cast inside the heat-insulating shell, which can effectively prevent heat from being dissipated into the air while ensuring structural stability, further improving heat utilization efficiency.

[0022] With such an arrangement, the cooperation between the water inlet valve and the water inlet can effectively control the amount of water entering the steam chamber, so as to achieve precise control over the amount of steam generated.

[0023] In some embodiments, the steam component further includes a thermostat, which is disposed in the steam chamber to detect the temperature in the steam chamber.

[0024] With such a configuration, the thermostat can effectively detect the temperature in the steam chamber, preventing the temperature from being too high while timely increasing the heating value of the heating element when the temperature is too low.

[0025] In some embodiments, the steam component further includes a water pump and a water tank, the water pump is connected between the water tank and the hot water pipe, and the water pump is configured to pump liquid in the water tank into the hot water pipe.

[0026] With such an arrangement, the amount of water pumped into the hot water pipe can be effectively controlled by the water pump, thereby controlling the amount of steam generated.

DETAILED DESCRIPTION

[0042] Handheld steam devices are increasingly used in people's lives. Typical steam devices such as steam irons, steam hot pots, etc. are relatively common. Their core function is to quickly heat and vaporize liquid water into high-temperature steam for people to iron and cook. In the related art, a handheld steam device has a steam component that generates steam. The steam component generally has a heating element and a steam chamber. Heat transfer can be carried out between the heating element and the steam chamber, and then the heat generated by the heating element can be transferred to the steam chamber. When the user turns on the handheld steam device, liquid water is directly passed into the steam chamber, and then vaporized into high-temperature steam by the heat generated by the heating element. After entering the steam chamber, the water first contacts the water point in the steam chamber. Because the heat is evenly distributed in the steam chamber, most of the water is vaporized at the first water point it contacts when it just enters the steam chamber. However, for the heating element, the part near the water point is more heat taken away by water vaporization, so the temperature drops faster. In contrast, the water vaporization speed near other parts of the heating element is slower, and the heat taken away is less, so the temperature drops slower. When the steam component detects that the temperature is lower than the threshold, it will start to reheat the entire heating element. Furthermore, due to the difference in the speed of temperature drop in different parts of the heating element, it is easy to cause the heating element to start to heat up again when the temperature of the heating element near the water point in the electric heating tube is lower than the threshold and other parts of the heating element still have a lot of heat, resulting in a waste of unused heat in the heating element, reducing the efficiency of heat utilization, and increasing the overall working temperature of the steam component. At the same time, water is concentrated at the water point and vaporized, and its vaporization speed and conversion rate are difficult to guarantee.

[0043] In order to solve the above problems, the present application provides a steam component and a steam generating device, wherein the heating element and the heat-conducting water pipe are arranged to be at least partially fitted, so that the liquid water flowing through the heat-conducting water pipe can be pre-heated with the heating element before entering the steam chamber inside the heat-insulating shell, so that in the process of heating to generate steam, the heat of each part of the heating element can be evenly and fully absorbed by the flowing water, thus avoiding the waste of heat and effectively improving the utilization efficiency of heat. At the same time, the water is pre-heated before entering the steam chamber and has a higher temperature. After entering the steam chamber, it can be more quickly and fully vaporized at the water entry point, reducing the water that cannot be vaporized in other parts of the steam chamber, thereby improving the vaporization speed and conversion rate of the water.

[0044] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0045] See also Figure 1-Figure 3 As shown, an embodiment of the present application provides a steam component 100, including: a heating body 110, the heating body 110 includes an insulation shell 111, a heating element 112 and a hot water pipe 113, the hot water pipe 113 and the heating element 112 are at least partially arranged to fit together so that the heating element 112 and the hot water pipe 113 can exchange heat.

[0046] Exemplarily, the heat conducting water pipe 113 may be a hollow structural member through which liquid water flows, and is made of heat conducting and heat resistant materials. For example, the heat conducting water pipe 113 may be made of metal materials such as stainless steel.

[0047] In addition, the heating element 110 can generate heat by supplying electricity. For example, the heating element 110 can be a structure such as an electric heating tube, which can release heat by supplying electricity for heating.

[0048] In the embodiment of the present application, liquid water flows in the tube cavity inside the hot water pipe 113, and the hot water pipe 113 is arranged to be in contact with at least a portion of the heating element 110. In this way, the hot water pipe 113 can exchange heat with the heating element 110, so that the liquid water in the hot water pipe 113 can absorb heat from the heating element 112, so that the temperature of the liquid water in the hot water pipe 113 increases.

[0049] That is, the heat of the heating element 112 is directly transferred to the hot water pipe 113 by being attached to the hot water pipe 113, so as to generate heat radiation to the lumen inside the hot water pipe 113, so as to increase the temperature of the hot water pipe 113 itself and its internal lumen. The hot water pipe 113 can be a hose or a rigid pipe, and the outer wall of the hot water pipe 113 is directly attached to the outer wall of the heating element 112 to absorb heat.

[0050] In addition, if Figure 1 as well as Figure 3 As shown, the insulation shell 111 is arranged around the outer peripheral side of the heating element 112 and the hot water pipe 113. A steam chamber 1111 is formed in the insulation shell 111, one end of the hot water pipe 113 is configured to be connected to a water source, and the other end of the hot water pipe 113 is configured to communicate with the steam chamber 1111, so that the liquid entering the steam chamber 1111 is vaporized. Among them, the insulation shell 111 can completely surround the heating element 112 and the hot water pipe 113 to reduce heat dissipation; or it can also partially surround the heating element 112 and the hot water pipe 113, so that part of the heating element 112 and the hot water pipe 113 are exposed to the outside, which is convenient for disassembly or maintenance. The insulation shell 111 can be made of a heat-conducting material, for example, the material of the insulation shell 111 can be an aluminum material, etc.; illustratively, an isolation layer made of a heat-insulating material can be additionally coated on the outside of the insulation shell 111 to prevent heat dissipation.

[0051] In the embodiment of the present application, the steam chamber 1111 inside the insulation shell 111 is the location where water is vaporized into steam, and the heating element 110 provides heat to the steam chamber 1111 so that the temperature inside the steam chamber 1111 can reach a high temperature that vaporizes liquid water into steam.

[0052] It can be understood that the steam cavity 1111 is a cavity inside the heat-insulating shell 111, and there is a thickness gap between the steam cavity 1111 and the heating element 110. The heating element 110 is not in direct contact with the steam cavity 1111, so as to prevent the steam from having an adverse effect on the heating element 110. Figure 2 As shown, Figure 2 The arrows in the figure indicate the flow direction of water in the hot water pipe 113. In the process of water entering the steam chamber 1111 and being vaporized, the heating element 110 first flows into the steam chamber 1111 and the liquid water first flows from the water source into one end of the hot water pipe 113 and flows along the hot water pipe 113, while absorbing the heat of the heating element 110 and the temperature increases. Finally, the water reaches the end of the hot water pipe 113 that is connected to the steam chamber 1111 and enters the steam chamber 1111, where it is heated and vaporized into steam.

[0053] like Figure 1 and Figure 2As shown, the end of the hot water pipe 113 communicating with the steam chamber 1111 can be directly connected to the opening of the steam chamber 1111, or can be connected to the opening of the steam chamber 1111 through another adapter tube 120. The adapter tube 120 can be a metal tube or a non-metallic hose, etc., to adapt to different positional relationships between the end of the hot water pipe 113 and the opening of the steam chamber 1111.

[0054] In order to ensure that the water temperature in the transfer tube 120 does not drop, the transfer tube 120 can be arranged to be attached to the heat-insulating shell 111 to absorb the heat of the heat-insulating shell 111. Regardless of the method used to connect the hot water pipe 113 and the steam chamber 1111, after entering the steam chamber 1111, the point on the inner wall of the steam chamber 1111 that the water first contacts is the water entry point.

[0055] Compared with the related art in which liquid water directly enters the steam chamber 1111 without being heated, the steam assembly 100 provided in the embodiment of the present application sets the heating element 110 and the hot water pipe 113 to be at least partially fitted, so that the liquid water in the water source connected to the hot water pipe 113 can absorb the heat of the heating element 110 in advance during the process of flowing through the hot water pipe 113 into the steam chamber 1111 inside the heat-insulating shell 111, so that the temperature of the liquid water increases. In this way, in the process of heating and generating steam, part of the heat generated by the part of the heating element 110 that fits the hot water pipe 113 is uniformly and fully absorbed by the flowing water, avoiding the waste of heat and effectively improving the utilization efficiency of heat. At the same time, the water is preheated before entering the steam chamber 1111 and has a higher temperature. After entering the steam chamber 1111, it can be more quickly and fully vaporized at the water entry point, reducing the water that cannot be vaporized in other parts of the steam chamber 1111, thereby improving the vaporization speed and conversion rate of the water.

[0056] In some embodiments, see Figure 2 and Figure 4 As shown, the contour shape of the hot water pipe 113 matches the contour shape of the heating element 112 , and the hot water pipe 113 is disposed on at least one side of the heating element 112 and fits the heating element 112 .

[0057] It can be understood that by matching the contour shape of the hot water pipe 113 with the contour shape of the heating element 112, the fit between the hot water pipe 113 and the heating element 112 can be increased, and the fitting area can be increased, thereby improving the heat transfer efficiency between the hot water pipe 113 and the heating element 112, improving the utilization rate of heat, and avoiding heat waste.

[0058] In some embodiments, the contour shape of the hot water pipe 113 can be set to a straight line, a curve, an S-shaped bend, a U-shaped bend, etc. as needed. Correspondingly, the contour shape of the heating element 112 can be set to a shape that matches the contour shape of the hot water pipe 113, for example, the contour shape of the heating element 112 and the contour shape of the hot water pipe 113 can be set to a curve shape that fits each other. Among them, if the contour shape of the heating element 112 is set to a curve shape, then the hot water pipe 113 can be attached to at least one side of the inner side and the outer side of the bending direction of the heating element 112. Alternatively, if the heating element 112 is set to a disc shape, the hot water pipe 113 can be set to an arc shape and coiled on the arc-shaped outer wall of the heating element 112.

[0059] It is understandable that the hot water pipe 113 can be attached to the outer wall of the heating element 112 in various forms. For example, the hot water pipe 113 can be attached to one side of the heating element 112, and both the hot water pipe 113 and the heating element 112 can be set as round tubes to achieve the contact with the outer wall; or multiple hot water pipes 113 can be set and attached to the outer wall of the heating element 112 from multiple directions at the same time; or the hot water pipe 113 can be set to be entirely wrapped around the outer side of the heating element 112, in which case the hot water pipe 113 is sleeved on the outer side of the heating element 112; or the hot water pipe 113 is attached to one side of the heating element 112 in a semi-enclosed form, covering a portion of the outer wall of the heating element 112, so as to expand the contact area between the two.

[0060] With such an arrangement, the contact area between the hot water pipe 113 and the heating element 112 is larger, so that the heat generated by the heating element 112 can be absorbed more fully and evenly, so as to preheat the water while improving the heat utilization efficiency.

[0061] For example, see Figure 4 The hot water pipe 113 includes an arc pipe segment 1131, a first straight pipe segment 1132 and a second straight pipe segment 1133. The first straight pipe segment 1132 and the second straight pipe segment 1133 are respectively connected to the two ends of the arc pipe segment 1131. The end of the first straight pipe segment 1132 away from the arc pipe segment 1131 is connected to the water source, and the end of the second straight pipe segment 1133 away from the arc pipe segment 1131 is connected to the steam chamber 1111.

[0062] like Figure 4As shown, the heat conducting water pipe 113 presents a U-shaped structure as a whole. The first straight pipe section 1132 and the second straight pipe section 1133 can be parallel or have a certain angle, and the arc pipe section 1131 enables the water flow direction in the heat conducting water pipe 113 to change smoothly. Specifically, the arc pipe section 1131 allows water to flow from the water source into the heat conducting water pipe 113, and then travel along the first straight pipe section 1132 in a straight direction, and make a smooth turn at the arc pipe section 1131, and then continue to flow in a straight line along the central axis direction of the second straight pipe section 1133. Since the space inside the heat insulation shell 111 is limited, it is necessary to extend the flow path length of the water flow as much as possible within a certain space. Therefore, this effect can be achieved by setting the arc pipe section 1131 to avoid the water flow moving along a single straight path, which causes the straight length of the heat conducting water pipe 113 to be too large.

[0063] See also Figure 5 As shown, it can be understood that, under the premise of using the first straight pipe segment 1132, the arc pipe segment 1131 and the second straight pipe segment 1133 as a group of hot water pipes 113, multiple hot water pipes 113 can be arranged at the same time as needed, and each hot water pipe 113 is connected through a transfer arc pipe segment 1134 or directly connected. Exemplarily, if the transfer arc pipe segment 1134 is used for connection, the end of the second straight pipe segment 1133 to be connected to the steam chamber 1111 can be connected to the transfer arc pipe segment 1134, and the bending direction of the transfer arc pipe segment 1134 is opposite to that of the arc pipe segment 1131. Subsequently, the end of the first straight pipe segment 1132 in another group of hot water pipes 113 to be connected to the water source is connected to the end of the transfer arc pipe segment 1134 that is away from the previous group of hot water pipes 113, so as to achieve the splicing of the two groups of hot water pipes 113. If direct connection is adopted, the second straight pipe section 1133 in the previous group of hot water pipes 113 can also be directly connected to the first straight pipe section 1132 in the next group of hot water pipes 113. In this way, multiple groups of U-shaped hot water pipes 113 can be spliced ​​into an S-shaped structure with multiple bends, which can provide a longer water flow path while ensuring that the overall length of the space where the hot water pipes 113 are located is short.

[0064] With such arrangement, the arc pipe segment 1131 , the first straight pipe segment 1132 and the second straight pipe segment 1133 can increase the flow path of water within a limited space, so that the water can be more fully preheated and the heat of various parts in the heating element 112 can be more fully utilized.

[0065] In some embodiments, see Figure 4 and Figure 6As shown, the end of the first straight pipe segment 1132 away from the arc pipe segment 1131 has a first bending portion 1135, and the first bending portion 1135 is configured to be connected to a water source; the end of the second straight pipe segment 1133 away from the arc pipe segment 1131 has a second bending portion 1136, and the second bending portion 1136 is configured to be connected to the steam chamber 1111.

[0066] In the embodiments of the present application, Figure 4 As shown, there is a certain angle between the first bend 1135 and the first straight pipe section 1132, and there is also a certain angle between the second bend 1136 and the second straight pipe section 1133. The first bend 1135 and the second bend 1136 can face the same direction, which is convenient for installing and removing the pipe, connection structure, etc. to be connected to the first bend 1135 or the second bend 1136. For example, the pipe can be sleeved to the outside of the first bend 1135 or the second bend 1136. Figure 6 As shown, the first bending portion 1135 can be connected to the water source through a pipe, and the second bending portion 1136 can be connected to the steam chamber 1111 through another pipe. The first bending portion 1135 and the second bending portion 1136 can be bent upward in the direction of gravity to prevent water leakage when the structure connected to the first bending portion 1135 or the second bending portion 1136 is disassembled.

[0067] With such arrangement, the first bending portion 1135 and the second bending portion 1136 can be easily connected to the water source and the steam chamber 1111 , and can buffer the instantaneous water flow.

[0068] In some embodiments, the heating element 112 and the hot water pipe 113 are welded. For example, the heating element 112 and the hot water pipe 113 can be spot welded or fully welded to improve the heat transfer efficiency between the heating element 112 and the hot water pipe 113.

[0069] In the embodiment of the present application, the heating element 112 and the hot water pipe 113 are connected by welding, so that a stable connection can be formed between the heating element 112 and the hot water pipe 113 without the aid of any connecting parts or adhesive layers, so that the heating element 112 can stably transfer heat to the hot water pipe 113 while reducing heat loss.

[0070] It is understandable that the heating element 112 and the heat conducting water pipe 113 may be connected by gluing or by connecting with a connector, and the connection method between the two may be adjusted according to actual production needs.

[0071] Illustratively, the heating element 112 provided in the embodiment of the present application may be an electric heating pipe; and the heat conducting water pipe 113 may be a stainless steel pipe.

[0072] The heating element 112 in the form of an electric heating tube can be powered from both ends of the heating element 112. At this time, both ends of the heating element 112 can protrude from the inside of the insulation shell 111 to connect to the power supply. The hot water pipe 113 can be an integrally formed stainless steel pipe, or a stainless steel pipe spliced ​​or welded in multiple sections. The surface of the portion where the heating element 112 in the form of an electric heating tube fits the hot water pipe 113 should be made of a heat-conducting material to smoothly conduct heat to the hot water pipe 113.

[0073] In this way, the heating element 112 in the form of an electric heating tube can quickly generate more heat, and the hot water pipe 113 in the form of a stainless steel tube has strong thermal conductivity, can quickly absorb the heat of the heating element 112 and heat the water fully and quickly.

[0074] Illustratively, in the embodiment of the present application, the insulation shell 111 may be an aluminum insulation shell.

[0075] In the embodiment of the present application, the insulation shell 111 in the form of an aluminum insulation shell can be an integrally molded insulation shell 111, or it can be an insulation shell 111 that is molded in modules and finally assembled into one. The aluminum form provides a variety of molding methods for the production of the insulation shell 111.

[0076] It can be understood that the thermal insulation shell 111 in the form of an aluminum thermal insulation shell has strong thermal conductivity, can fully absorb the heat from the heating element 112, and evenly transfer it to every part of the steam chamber 1111, so that water flowing into any part of the steam chamber 1111 can be quickly vaporized.

[0077] Exemplarily, the heat-insulating shell 111, the heating element 112 and the heat-conducting water pipe 113 are an integral die-cast structure.

[0078] In a specific implementation, the hot water pipe 113 and the heating element 112 can be first connected and fixed to form a stable whole, and then the heat-conducting water pipe 113 can be die-casted inside the insulation shell 111 by a die-casting process, so that the insulation shell 111, the heating element 112, and the hot water pipe 113 are a die-cast integrated structure. Alternatively, the hot water pipe 113 and the heating element 112 can be directly placed at a preset position in the mold, and then the insulation shell 111 is die-cast, so that after die-casting, the hot water pipe 113 and the heating element 112 are located at a fixed preset position inside the insulation shell 111. After die-casting, the insulation shell 111 is tightly wrapped around the outer periphery of the heating element 112 and the hot water pipe 113, forming an effective protection for the heating element 112 and the hot water pipe 113, and the heating element 112 and the hot water pipe 113 will not shift or loosen. At the same time, there is a small gap between the heating element 112 and the insulation shell 111, and the heating element 112 can effectively transfer heat to the steam chamber 1111 in the insulation shell 111. The die-casting method can also save the steps of connecting the heating element 112 and the heat-conducting water pipe 113 to the inside of the insulation shell 111, thereby improving production efficiency.

[0079] In this way, the heating element 112 and the heat conducting water pipe 113 are die-cast inside the heat-insulating shell 111, which can effectively prevent heat from being dissipated into the air while ensuring structural stability, thereby further improving heat utilization efficiency.

[0080] In some embodiments, see Figure 2 and Figure 6 The steam component 100 also includes a water inlet valve 130. The insulation shell 111 has a water inlet 1112 connected to the steam chamber 1111. The water inlet valve 130 is arranged at the water inlet 1112 and connected to the hot water pipe 113. The water inlet valve 130 is configured to open and close the water inlet 1112.

[0081] In the embodiment of the present application, the water inlet 1112 can be opened at the side, top or bottom of the insulation shell 111, and the number of the water inlet 1112 can be set to one or more, corresponding to multiple hot water pipes 113. For each water inlet 1112, a water inlet valve 130 is connected in a sealed manner, and the water inlet valve 130 can be opened and closed as needed to achieve the closure or opening of the water inlet 1112. At the same time, the opening and closing degree of the water inlet valve 130 can also be adjusted to achieve the control of the water flow rate. When more steam needs to be generated, the opening degree of the water inlet valve 130 increases, the water flow entering the steam chamber 1111 also increases, and the steam generation efficiency is improved; when less steam needs to be generated, the opening degree of the water inlet valve 130 decreases, the water flow entering the steam chamber 1111 also decreases, and the steam generation efficiency decreases; when it is necessary to stop generating steam, the water inlet valve 130 can be directly closed to shut off the water flow entering the steam chamber 1111 to completely stop the generation of steam.

[0082] In the embodiment of the present application, a water inlet valve 130 is provided at the water inlet 1112. Thus, the cooperation between the water inlet valve 130 and the water inlet 1112 can effectively control the amount of water entering the steam chamber 1111, so as to achieve precise control of the amount of steam generated.

[0083] In some embodiments, see Figure 3 As shown, the steam assembly 100 further includes a temperature controller 140 , which is disposed in the steam chamber 1111 to detect the temperature in the steam chamber 1111 .

[0084] In the embodiment of the present application, the thermostat 140 can be completely disposed in the steam chamber 1111, or partially disposed in the steam chamber 1111 and partially located outside the steam chamber 1111. The thermostat 140 can sense and detect the temperature inside the steam chamber 1111, and an electrical connection is implemented between the thermostat 140 and the heating element 112. The temperature inside the steam chamber 1111 sensed by the thermostat 140 actually represents the degree to which the heat of the heating element 112 near the steam chamber 1111 is absorbed by the steam chamber 1111. The lower the temperature inside the steam chamber 1111, the more the heat of the heating element 112 near the steam chamber 1111 is absorbed and utilized. At this time, the temperature of the heating element 112 near the steam chamber 1111 also decreases accordingly. When the thermostat 140 detects that the temperature inside the steam chamber 1111 is higher than the preset threshold, it will control to reduce or stop the heat generation of the heating element 112; when the thermostat 140 detects that the temperature inside the steam chamber 1111 is lower than the preset threshold, it will control to start or increase the heat generation of the heating element 112.

[0085] It can be understood that since the heat conducting water pipe 113 and the heating element 112 are at least partially in contact with each other in the embodiment of the present application, the heat utilization efficiency of each part of the heating element 112 is similar, and the temperature drop rate of each part of the heating element 112 is similar. Therefore, when the thermostat 140 detects that the temperature is lower than the threshold value and increases the heat generation of the heating element 112, the temperature of a certain part of the heating element 112 will not be too high, thereby avoiding the safety hazard caused by the excessive temperature of a certain part.

[0086] It can be seen that the temperature controller 140 can effectively detect the temperature in the steam chamber 1111, prevent the temperature from being too high, and timely increase the heating value of the heating element 112 when the temperature is too low.

[0087] In some embodiments, please refer to Figure 6 As shown, the steam assembly 100 further includes a water pump 150 and a water tank 160 . The water pump 150 is connected between the water tank 160 and the hot water pipe 113 . The water pump 150 is configured to pump the liquid in the water tank 160 into the hot water pipe 113 .

[0088] In the embodiment of the present application, the water pump 150 can pump the water in the water tank 160 into the hot water pipe 113 according to the amount of steam actually required. A certain amount of water can be stored in the water tank 160 in advance to stably provide water to the hot water pipe 113.

[0089] In this way, the amount of water pumped into the hot water pipe 113 can be effectively controlled by the water pump 150, thereby controlling the amount of steam generated.

[0090] An embodiment of the present application also provides a steam generating device, comprising a device body and the steam component provided in the above embodiment.

[0091] Among them, the steam generating device can be a steam iron, a handheld steam brush, a hanging iron, a steam hot pot, etc., as long as it can work based on the principle of generating steam through the above-mentioned steam components, and there is no limitation here.

[0092] In addition, the steam component can be connected to the outside or inside of the device body, and the device body can be a component that realizes other functions. For example, when the steam generating device is a steam iron, the device body is the main body of the iron. The steam component is arranged inside the iron, and the end of the hot water pipe of the steam component that is connected to the water source has an outward opening, allowing the user to add water to the hot water pipe.

[0093] Among them, the structure and working principle of the steam component have been introduced in detail in the above embodiments and will not be repeated here.

[0094] The present application provides a steam component and a steam generating device, wherein the heating element and the heat-conducting water pipe are arranged to be at least partially fitted, so that the liquid water flowing through the heat-conducting water pipe can be pre-heated with the heating element before entering the steam chamber inside the heat-insulating shell, so that in the process of heating and generating steam, the heat of each part of the heating element can be evenly and fully absorbed by the flowing water, thus avoiding the waste of heat and effectively improving the utilization efficiency of heat. At the same time, the water is pre-heated before entering the steam chamber and has a higher temperature. After entering the steam chamber, it can be more quickly and fully vaporized at the water entry point, reducing the water that cannot be vaporized in other parts of the steam chamber, thereby improving the vaporization speed and conversion rate of the water.
