Description

Technical Field

[0001] The present invention relates to the technical field of electrical appliances, and particularly to an appliance for heating by using steam and a health preservation kettle. Background Art

[0002] Currently, with the development of technology, health preservation kettles using steam heating have emerged. In existing health preservation kettles, a steam generator and a steam channel that is matched and connected to the steam generator and used for introducing air into the kettle body are usually provided. For example, in the health preservation machine disclosed in CN217161744U, the steam channel is specifically provided at the top of the kettle body, which affects the placement and removal of the kettle body and is very inconvenient; also, for example, in the liquid heater with steam heating disclosed in CN213248424U, a convex air guiding structure is provided at the bottom of the kettle body, and the steam channel is arranged in the air guiding structure. However, in order to avoid backflow, the air guiding structure needs to protrude into the cavity of the container, which will hinder the placement and removal of food or materials in the kettle; also, for example, in the health preservation kettle disclosed in CN208301475U, an inverted U-shaped pipe needs to be used as the steam channel and is located on the side wall of the kettle body close to the handle, which will cause the structure of this side wall to be too thick and undoubtedly increase the production cost; also, for example, in the steam heating device and kettle body assembly disclosed in CN217161742U, the steam channel is provided in the handle of the kettle body, which causes the heat in the steam channel to be easily transferred to the handle, making the handle hot and then making the placement and removal of the kettle body inconvenient. It can be seen that there are many problems with the air intake structures in existing health preservation kettles. Therefore, there is an urgent need for an appliance with a newly designed air intake structure. Summary of the Invention

[0003] In order to overcome at least one of the above-mentioned defects of the prior art, according to one aspect of the present invention, there is provided an appliance for heating by using steam, including: a base body, a kettle body, and a steam generator. The steam generator is arranged in the base body, and the kettle body is used to be placed on the base body;

[0004] The base body is provided with a first connector for connecting the steam generator, and a second connector is provided at the lower part of the handle of the kettle body and the second connector leads to the inner cavity of the kettle body. The first connector and the second connector are detachably connected;

[0005] A one-way structure is arranged in the first connector and / or the second connector; or, a one-way structure is arranged between the first connector and the second connector, and the direction of allowed flow of the one-way structure is the same as the steam flow direction;

[0006] When the kettle body is placed on the base body, the first connector and the second connector are plugged and connected.

[0007] In an embodiment of the present application, a first through hole is provided through the top wall of the seat body facing the kettle body. One interface of the first connector is located at the first through hole and the other interface communicates with the steam generator;

[0008] The second connector is arranged in the cavity area at the lower part of the handle and a second through hole is provided through the bottom wall of the cavity area. One connector of the second connector extends out of the second through hole and the other end communicates with the inner cavity of the kettle body;

[0009] When the kettle body is placed on the seat body, one connector of the second connector is inserted and communicated with one interface of the first connector.

[0010] In an embodiment of the present application, a connecting pipe is communicated with the inner cavity side wall of the kettle body and the connecting pipe extends outwards to communicate with the second connector;

[0011] A check member is sealed at the port of the connecting pipe located on the inner cavity side wall.

[0012] In an embodiment of the present application, the check member has a check through hole provided therethrough. A plurality of check pieces are provided at the end of the check through hole, and the plurality of check pieces are in an arc shape arched outwards.

[0013] In an embodiment of the present application, a one-way valve is provided in the check through hole, and the direction allowed by the one-way valve is the same as the steam flow direction.

[0014] In an embodiment of the present application, a first area for placing the kettle body is provided at the top end of the seat body, and an assembly notch penetrating the top wall of the seat body is provided at the first area;

[0015] The steam generator includes a housing and a cover body. The housing is arranged at the assembly notch of the seat body. A heating tube is arranged in the housing, and a steam generating groove with an open top end is arranged in the housing; The cover body covers the notch of the assembly notch and is detachably connected to the housing or the seat body, and the cover body is used to block the top opening of the steam generating groove.

[0016] In an embodiment of the present application, the steam generator includes a housing and a heating tube arranged in the housing. A spirally arranged steam generating groove is arranged in the housing, and the steam generating groove has an inner connector and an outer interface;

[0017] An inlet and an outlet are arranged in the housing. The inlet conducts the inner connector of the steam generating groove, and the outlet communicates with the outer interface of the steam generating groove. The heating tube includes an arc-shaped heating section and the arc-shaped heating section is located at the outer circle of the spiral steam generating groove.

[0018] In an embodiment of the present application, the diameter of the arc-shaped heating section is larger than the width of the notch of the spiral steam generating groove.

[0019] In an embodiment of the present application, the one-way structure is disposed within the second connector;

[0020] The one-way structure is spherical in shape.

[0021] In an embodiment of the present application, the second connector has a ventilation cavity. One side of the ventilation cavity communicates with the steam generator through a first channel, and the other side is used for the first connector to be inserted and connected through a second channel;

[0022] A connecting pipe is movably disposed within the second connector. The side wall of the connecting pipe has a through ventilation notch.

An elastic member is disposed between the other end of the connecting pipe and the inner wall of the ventilation cavity;

[0023] When the first connector is inserted into the second channel of the second connector, the first connector abuts against the connecting pipe and drives the connecting pipe to move downward, so that the ventilation notch of the connecting pipe is exposed and communicates with the ventilation cavity;

[0024] When the first connector leaves the second channel, the elastic member resets and drives the connecting pipe to move upward, so that the seal seals the port of the second channel.

[0025] According to another aspect of the present application, there is provided a health preservation kettle, including the above-mentioned appliance that uses steam for heating.

[0026] In summary, the appliance for heating using steam and the health preservation kettle provided by the present invention have the following technical effects:

[0027] Different from the prior art where the steam channel is disposed at the top of the kettle body, which affects the taking and placing, or the bottom air guiding structure hinders the taking and placing of food, the connection structure of the steam channel of this appliance is disposed below the handle of the kettle body. During daily use, when the user takes and places the kettle body, they will not be interfered by the steam channel structure and can operate more smoothly, greatly improving the convenience of use.

[0028] Moreover, compared with the situation in the prior art where the side wall structure of the kettle body is too thick due to the setting of the steam channel, increasing the production cost, this appliance avoids the complex design of other parts of the kettle body by setting the connector below the handle, making the overall structure of the kettle body more concise and reasonable, and effectively reducing the production cost.

[0029] At the same time, the problem in the prior art that the steam channel disposed within the handle causes the handle to be hot can also be solved in this appliance. The connection head of the steam channel of this appliance is disposed below the handle, and the heat within the steam channel will not be directly transferred to the handle. When the user takes and places the kettle body, they will not be scalded due to the overheating of the handle, greatly improving the safety of use.

[0030] Finally, the one-way structure provided inside the first connector and / or the second connector, or the one-way structure provided between the first connector and the second connector, can effectively prevent the liquid and steam in the kettle body from flowing back to the steam generator. This not only ensures the normal operation of the steam generator and extends its service life, but also avoids potential safety hazards and equipment failures caused by liquid backflow.

Detailed Embodiments

[0041] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0042] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0044] The embodiments of the present invention disclose an appliance heated by steam and a health care kettle having the appliance. Of course, in addition to the health care kettle, it can also be other kitchen equipment heated by steam.

[0045] The appliance in this embodiment is described by taking the health care kettle as an example. This appliance is heated by steam and has the following advantages. The health care machine in this embodiment uses steam heating, which can directly transfer heat to the liquid and ingredients in the kettle body, so the heating is more uniform and the heating efficiency is higher. Moreover, during the process of heating the ingredients, water and other substances in the kettle body by steam, the ingredients, water and other substances in the kettle body can also be turbulently flowed to promote their movement, so the heating uniformity and heating efficiency can be improved, which is beneficial to shortening the heating time and reducing energy consumption.

[0046] However, in actual use, it is found that there are many problems with the air intake structure in the existing health care kettles, so the air intake structure is improved.

[0047] The following will describe the appliance in this embodiment with reference to the attached Figure 1 - attached Figure 9 Describe the appliance in this embodiment. The attached Figure 1 is a schematic structural diagram of the appliance in this embodiment, and the attached Figure 2 is a cross-sectional view of the internal structure of the appliance in this embodiment, and the attached Figure 3 is a partial enlarged view of the A position in the attached Figure 2 and the attached Figure 4 is a schematic diagram of the disassembled state of the appliance in this embodiment, and the attached Figure 5 is a schematic diagram of the disassembled state of the steam generator of the appliance in this embodiment.Figure 6 Cross-sectional view of the interior of the steam generator of the appliance according to this embodiment, attached Figure 7 In which a is a top view of the steam generator of the appliance according to this embodiment, attached Figure 7 In which b is another cross-sectional view of the interior of the steam generator of the appliance according to this embodiment, attached Figure 8 Schematic structural view of the check member of the appliance according to this embodiment, attached Figure 9 Cross-sectional view of the interior of the second connector of the appliance according to this embodiment.

[0048] Specifically, this appliance includes a base 1, a kettle body 2, and a steam generator 3. The steam generator 3 is disposed within the base 1, and the kettle body 2 is adapted to be placed on the base 1;

[0049] The base 1 is provided with a first connector 4 for communicating with the steam generator 3. A second connector 5 is disposed below the handle 21 of the kettle body 2 and the second connector 5 conducts to the inner cavity 22 of the kettle body 2. The first connector 4 and the second connector 5 are detachably connected;

[0050] A one-way structure 6 is disposed within the first connector 4 and / or the second connector 5; alternatively, a one-way structure 6 is disposed between the first connector 4 and the second connector 5, and the direction of flow allowed by the one-way structure 6 is the same as the direction of steam flow;

[0051] When the kettle body 2 is placed on the base 1, the first connector 4 and the second connector 5 are plugged and communicated.

[0052] When this appliance is in operation, the kettle body 2 is placed on the base 1, and the first connector 4 on the base 1 for communicating with the steam generator 3 and the second connector 5 below the handle 21 of the kettle body 2 are plugged and communicated.

[0053] The steam generator 3 operates to generate steam. The steam enters through the first connector 4. Since a one-way structure 6 is disposed within the first connector 4 and / or the second connector 5, or a one-way structure 6 is disposed between the first connector 4 and the second connector 5, the steam can only flow along the direction allowed by the one-way structure 6, from the first connector 4 through the second connector 5 into the inner cavity 22 of the kettle body 2 to heat the ingredients etc. within the kettle body 2.

[0054] During the heating process, the one-way structure 6 effectively prevents the liquid, steam, etc. within the kettle body 2 from flowing back into the steam generator 3, ensuring the normal operation of the steam generator 3.

[0055] When it is necessary to remove the kettle body 2, the kettle body 2 is directly lifted from the base 1, the first connector 4 and the second connector 5 are separated, and the steam passage is disconnected.

[0056] It can be seen that different from the steam channels in the prior art being arranged at the top of the kettle body 2, which affects the taking and placing, or the bottom air guiding structure hindering the taking and placing of food, the connecting structure of the steam channel of this appliance is arranged below the handle 21 of the kettle body 2. During daily use, when the user takes and places the kettle body 2, they will not be disturbed by the steam channel structure and can operate more smoothly, greatly improving the convenience of use.

[0057] Moreover, compared with the situation in the prior art where the side wall structure of the kettle body 2 is too thick due to the arrangement of the steam channel, thereby increasing the production cost, this appliance avoids the complex design of other parts of the kettle body 2 by arranging a connector below the handle 21, making the overall structure of the kettle body 2 more concise and reasonable, and effectively reducing the production cost.

[0058] At the same time, the problem in the prior art that the handle 21 gets hot due to the steam channel being arranged inside the handle can also be solved in this appliance. The connector of the steam channel is arranged below the handle 21, and the heat in the steam channel will not be directly transferred to the handle 21. When the user takes and places the kettle body 2, they will not be scalded due to the overheating of the handle 21, greatly improving the safety of use.

[0059] Finally, the one-way structure 6 arranged in the first connector 4 and / or the second connector 5, or the one-way structure 6 arranged between the first connector 4 and the second connector 5, can effectively prevent the liquid and steam in the kettle body 2 from flowing back to the steam generator 3. This not only ensures the normal operation of the steam generator 3 and extends its service life, but also avoids potential safety hazards and equipment failures caused by liquid backflow.

[0060] Specifically, as shown in the attached Figure 3 In the illustrated embodiment, the one-way structure 6 is specifically arranged in the second connector 5.

[0061] In the illustrated embodiment, the one-way structure 6 can be specifically spherical.

[0062] When this appliance is working, the spherical one-way structure 6 in the second connector 5 has extremely small resistance to the forward flow of steam. The steam can pass through smoothly with a small pressure loss, ensuring the high efficiency of steam transmission. In scenarios where steam needs to quickly enter the kettle body 2 for heating, this design can quickly meet the demand, improve the heating efficiency of the health kettle, and save the user's waiting time. At the same time, it can quickly respond and block the channel under reverse pressure, effectively preventing backflow. Compared with other complex one-way structures 6, the action is faster and more reliable, greatly improving the stability and effectiveness of the one-way conduction function.

[0063] Moreover, by adopting a spherical shape as the one-way structure 6, the design is extremely simple. The structure of the sphere itself is single, and it is not easy to have faults such as loose parts and jamming in the second connector 5. During long-term use, when the spherical one-way structure 6 is subjected to the impact of steam and possible backflow substances, due to its smooth surface, the wear is relatively uniform and the durability is strong. This simple and durable structural design reduces the manufacturing difficulty and cost of the one-way structure 6, and at the same time reduces the frequency of appliance repair and replacement caused by the failure of the one-way structure 6, providing a more reliable use experience for users.

[0064] Specifically, as shown in Figure 2 and Figure 3 shown, the seat body 1 is provided with a first through hole 11 penetrating through the top wall facing the kettle body 2. One interface of the first connector 4 is located at the first through hole 11 and the other interface communicates with the steam generator 3;

[0065] The second connector 5 is arranged in the cavity area 211 at the lower part of the handle 21 of the kettle body 2, and a second through hole 212 is penetrated through the bottom wall of the cavity area 211. One connector of the second connector 5 extends out of the second through hole 212 and the other end communicates with the inner cavity 22 of the kettle body 2;

[0066] When the kettle body 2 is placed on the seat body 1, one connector of the second connector 5 is inserted and communicated with one interface of the first connector 4.

[0067] When the appliance is working, when the user places the kettle body 2 on the seat body 1, the connector of the second connector 5 extending out of the second through hole 212 will accurately be inserted into the interface of the first connector 4 located at the first through hole 11, thereby constructing a steam transmission channel from the steam generator 3, through the first connector 4 and the second connector 5, and finally into the kettle body 2. The steam enters the kettle body 2 along this channel to heat the ingredients in the kettle. When the heating is completed, the user picks up the kettle body 2 and leaves the seat body 1, and the second connector 5 and the first connector 4 are immediately separated, and the steam transmission channel is disconnected, and the steam generated by the steam generator 3 no longer enters the kettle body 2.

[0068] It can be seen that the seat body 1 and the kettle body 2 realize the connection of the steam channel through the ingenious cooperation of the first through hole 11, the first connector 4, the second through hole 212 and the second connector 5. This design makes full use of the space on the top wall of the seat body 1 and the lower part of the handle 21 of the kettle body 2, making the overall structure more compact. Compared with the complex and space-consuming methods of setting the steam channel on the top, bottom or side wall of the kettle body 2, it greatly optimizes the internal structure layout of the appliance and improves the space utilization rate.

[0069] Moreover, the first connector 4 and the second connector 5 are respectively arranged at specific through-hole positions. During installation, they only need to be placed correspondingly and connected, with simple and clear operation. During later maintenance, if there is a problem with the first connector 4 or the second connector 5, since their positions are clear and relatively independent, it is convenient to disassemble and replace components, reducing the maintenance cost and difficulty and improving the repair efficiency.

[0070] More importantly, the first connector 4 and the second connector 5 are connected in a plug-in manner, and their positions are precisely designed. When the kettle body 2 is placed on the base body 1, it can ensure a tight connection, and it is not easy to have a leakage phenomenon during the steam transmission process. The stable steam transmission not only ensures the consistency of the heating effect but also avoids energy waste and safety hazards that may be caused by steam leakage, improving the overall performance of the appliance.

[0071] Specifically, as shown in the appendix Figure 3 As shown, a connecting pipe 221 communicates with the side wall of the inner cavity 22 of the kettle body 2, and the connecting pipe 221 extends outward to communicate with the second connector 5;

[0072] A check member 7 is sealed at the port of the connecting pipe 221 on the side wall of the inner cavity 22.

[0073] When the appliance is working, when the pressure inside the kettle body 2 changes, such as after stopping heating, the steam inside the kettle condenses and the pressure decreases, or there may be a tendency of liquid backflow during the operation process, the check member 7 plays a key role. The check member 7 is sealed at the port of the connecting pipe 221 on the side wall of the inner cavity 22. When the food inside the kettle body 2 attempts to flow back from the inner cavity 22 of the kettle body 2 to the connecting pipe 221, the check member 7 will automatically close the port under the action of the pressure difference to prevent the backflow phenomenon from occurring.

[0074] It can be seen that adding the check member 7 at the port of the connecting pipe 221 improves the ability of the appliance to prevent food backflow, especially in the end area of the connecting pipe 221, to avoid bonding or blocking the port of the connecting pipe 221.

[0075] Specifically, as shown in the appendix Figure 3 And as shown in the appendix Figure 8 As shown, the check member 7 has a check through-hole 71 arranged through it, and a plurality of check pieces 72 are arranged at the end of the check through-hole 71. The plurality of check pieces 72 are in an arc shape arched outward. It should be noted that when exhausting steam, the check pieces 72 can elastically deform outward, and the check pieces 72 cannot deform inward because the plurality of check pieces 72 resist each other, thereby preventing food from entering the pipe.

[0076] When this appliance is working, steam starts from the steam generator 3 and successively passes through the first connector 4 of the base body 1, the second connector 5 at the lower part of the handle 21 of the kettle body 2, and the connecting pipe 221, and finally reaches the check member 7. Due to the certain pressure of the steam, when the steam impacts the check member 7, the pressure acting on the plurality of check pieces 72 which are arched outward in an arc shape will cause the check pieces 72 to open outward, and the steam can smoothly pass through the check through-hole 71 and enter the inner cavity 22 of the kettle body 2 to heat the food materials in the kettle and so on.

[0077] When there is a pressure change in the kettle, such as the pressure decreasing due to steam condensation, or when there is a tendency for the liquid in the kettle to flow back due to improper operation or other reasons, the flowing-back liquid or steam exerts a reverse pressure on the check piece 72. At this time, under the action of the reverse pressure, the check piece 72 will quickly move closer to the central position of the check through-hole 71, and the plurality of check pieces 72 will fit together, thus tightly closing the check through-hole 71 to prevent food from sticking or blocking the port of the connecting pipe 221.

[0078] It can be seen that the design of the plurality of check pieces 72 arched outward in an arc shape greatly enhances the check ability of the check member 7. Under the action of the forward steam pressure, the check pieces 72 can quickly open to ensure the smooth passage of the steam; while when the reverse pressure appears, the check pieces 72 can quickly and tightly fit together to effectively prevent backflow to prevent food from sticking or blocking the port of the connecting pipe 221.

[0079] Specifically, a one-way valve is arranged in the check through-hole 71, and the allowed direction of the one-way valve is the same as the steam flow direction.

[0080] When this appliance is working, during the heating process or after stopping heating, if the pressure in the kettle changes, resulting in a tendency for the liquid or steam to flow back, the flowing-back substance will impact the one-way valve, but due to the one-way conduction characteristic of the one-way valve, it will prevent the flowing-back substance from passing through in the reverse direction.

[0081] It can be seen that it can effectively resist the occurrence of backflow, significantly reducing the risk of damage to the steam generator 3 due to backflow, thereby prolonging the overall service life of the appliance and reducing the maintenance cost of the user and the equipment replacement frequency.

[0082] Moreover, the setting of the one-way valve enables more precise control of the steam flow direction. Only when the steam flows in the normal working direction, the one-way valve will open to ensure the stable and efficient entry of the steam into the kettle body 2. This avoids the reduction of heating efficiency caused by steam leakage or backflow, ensuring that the food materials in the kettle can be heated evenly and quickly, and improving the heating performance and user experience of the health kettle.

[0083] Specifically, as shown in the appendix Figure 1 and the appendix Figure 4As shown in the figure, the top of the base body 1 is provided with a first area 12 for placing the kettle body 2, and an assembly notch 121 penetrating the top wall of the base body 1 is provided at the first area 12;

[0084] The steam generator 3 includes a housing 31 and a cover body 32. The housing 31 is arranged at the assembly notch 121 of the base body 1. A heating tube 33 is arranged inside the housing 31, and a steam generating groove 311 with an open top end is arranged on the housing 31; The cover body 32 covers the notch of the assembly notch 121 and is detachably connected to the housing 31 or the base body 1. The cover body 32 is used to block the top opening of the steam generating groove 311.

[0085] When the appliance is working, the kettle body 2 is placed in the first area 12 at the top of the base body 1. The assembly notch 121 in the first area 12 is closely matched with the steam generator 3, and the housing 31 of the steam generator 3 therein is arranged at the assembly notch 121 of the base body 1.

[0086] After the steam generator 3 is started, the heating tube 33 in the housing 31 starts to work, and electrical energy is converted into heat energy to heat the water in the steam generating groove 311.

[0087] As the temperature rises, the liquid gradually vaporizes into steam, and the steam continuously accumulates in the steam generating groove 311. Since the cover body 32 covers the notch of the assembly notch 121 and is detachably connected to the housing 31 or the base body 1, it effectively blocks the top opening of the steam generating groove 311, so that the steam can only pass through a specific channel, that is, through the steam generating groove 311.

[0088] Since the first connector 4 is connected to the steam generator 3, the steam will flow into the first connector 4, then into the second connector 5, and finally into the kettle body 2 to heat the ingredients in the kettle, etc.

[0089] When maintenance, cleaning or component replacement of the steam generator 3 is required, the cover body 32 can be detached from the notch of the assembly notch 121, so as to conveniently access components such as the steam generating groove 311 and the heating tube 33 inside the housing 31.

[0090] It can be seen that the steam generator 3 is cleverly arranged at the assembly notch 121 of the base body 1, making full use of the internal space of the base body 1, so that the overall structure is more compact and reasonable. This design avoids problems such as occupying extra space and complex connection caused by the external placement of the steam generator 3, and improves the space utilization rate and overall aesthetics of the appliance.

[0091] Moreover, the detachable connection design of the cover 32 with the housing 31 or the base 1 greatly facilitates the maintenance and cleaning of the steam generator 3. Users can easily open the cover 32 to clean the inside of the steam generation tank 311, removing scale, impurities, etc., ensuring the normal operation of the steam generator 3 and the cleanliness of the steam. At the same time, for vulnerable components such as the heating tube 33, it is also convenient to inspect, repair or replace after removing the cover 32, reducing the maintenance cost and difficulty.

[0092] Specifically, as shown in the Figure 5 - attached Figure 7 figure, the steam generator 3 includes a housing 31 and a heating tube disposed inside the housing 31. A spirally arranged steam generation tank 311 is provided inside the housing 31, and the steam generation tank 311 has an inner joint 312 and an outer interface 313.

[0093] An inlet 314 and an outlet 315 are provided inside the housing 31. The inlet 314 conducts to the inner joint 312 of the steam generation tank 311, and the outlet 315 communicates with the outer interface 313 of the steam generation tank 311. The heating tube includes an arc-shaped heating section 331 and the arc-shaped heating section 331 is located at the outer circle of the spiral steam generation tank 311.

[0094] When the appliance is working, water can flow in from the inlet 314. The inlet 314 conducts to the inner joint 312 of the steam generation tank 311, and the liquid thus enters the spirally arranged steam generation tank 311.

[0095] At this time, the heating tube starts to work, converting electrical energy into heat energy. The arc-shaped heating section 331 of the heating tube is located at the outer circle of the spiral steam generation tank 311 to heat the liquid in the steam generation tank 311. Since the steam generation tank 311 is spiral, during the flow of the liquid in the tank, it can fully absorb the heat emitted by the arc-shaped heating section 331 and gradually vaporize into steam. As the steam is continuously generated, the steam accumulates in the steam generation tank 311 and flows through the outer interface 313 of the steam generation tank 311 to the outlet 315. Finally, the steam is discharged through the outlet 315 and enters the steam transmission channel composed of the first connector 4 and the second connector 5 connected to the steam generator 3, for heating the ingredients in the kettle body 2, etc.

[0096] It should be noted that the heating tube heats the entire housing 31, and the temperature is the highest at the position corresponding to the outer circle of the spiral steam generation tank 311 and gradually decreases towards the inside. When working, the water enters the spiral steam generation tank 311 and flows, and there will be a gradually heating process, so that the steam is mainly generated in the outer circle, and the generated steam can quickly enter the steam transmission channel composed of the first connector 4 and the second connector 5 through the outlet 315.

[0097] It can be seen that the arc-shaped heating section 331 of the heating pipe is arranged on the outer circle of the steam generation tank 311 and is closely attached to the spiral steam generation tank 311. This design enables the heat generated by the heating pipe to be directly and efficiently transferred to the water in the steam generation tank 311, greatly improving the heat conduction efficiency. Compared with the traditional heating method, heat loss is reduced, the liquid can be converted into steam in a shorter time, the working efficiency of the steam generator 3 is improved, and energy consumption is saved.

[0098] Moreover, the steam generation tank 311 is arranged in a spiral shape, increasing the flow path and heating area of the liquid within the limited housing 31. During the flow of the liquid in the spiral groove, it can be heated multiple times and fully absorb heat, achieving efficient utilization of space. At the same time, this compact structural design enables the steam generator 3 to have a strong steam generation capacity without occupying too much space, contributing to the miniaturization and integration design of the entire appliance.

[0099] Specifically, as shown in the attached Figure 7 figure, the diameter of the arc-shaped heating section 331 is larger than the width of the notch of the spiral steam generation tank 311. In this way, the diameter of the arc-shaped heating section 331 being larger than the width of the notch of the steam generation tank 311 can achieve a larger range of heat radiation coverage for the steam generation tank 311. Compared with the situation where the diameter of the heating section is similar to or smaller than the width of the notch, more heat can be directly radiated to the outer wall of the steam generation tank 311, reducing heat loss during the heat transfer process and improving the heat utilization efficiency. This enables the steam generator 3 to convert the liquid into steam in a shorter time, significantly increasing the steam generation speed and meeting the user's demand for rapid heating.

[0100] Specifically, as shown in the attached Figure 9 figure, a steam anti-blowout structure is also provided inside the second connector 5 in this embodiment. It has been found that during actual use, when the user picks up the kettle body 2, that is, when the first connector 4 is pulled out from the second connector 5, a certain amount of steam will be ejected from the second connector 5, which brings a very bad user experience and there is even a possibility of being scalded by the high-temperature steam.

[0101] Therefore, a steam anti-blowout structure is provided inside the second connector 5 in this embodiment to prevent steam from being ejected from the second connector 5 when the first connector 4 is pulled out. The specific structure is as follows: The second connector 5 has a ventilation cavity 51. One side of the ventilation cavity 51 is connected to the steam generator 3 through a first channel 52, and the other side is used for the first connector 4 to be inserted and connected through a second channel 53;

[0102] A connecting pipe 54 is movably arranged in the second connector 5. The side wall of the connecting pipe 54 has a through ventilation notch 541. One end of the connecting pipe 54 is located in the second channel 53, and the other end of the connecting pipe 54 is located in the ventilation cavity 51 and is provided with a seal 55. An elastic member 56 is arranged between the other end of the connecting pipe 54 and the inner wall of the ventilation cavity 51;

[0103] When the first connector 4 is inserted into the second channel 53 of the second connector 5, the first connector 4 abuts against the connecting pipe 54 and drives the connecting pipe 54 to move downward, so that the ventilation notch 541 of the connecting pipe 54 is exposed and communicated with the ventilation cavity 51;

[0104] When the first connector 4 leaves the second channel 53, the elastic member 56 resets and drives the connecting pipe 54 to move upward, so that the seal 55 seals the port of the second channel 53.

[0105] When the appliance is working, when the first connector 4 is inserted into the second channel 53 of the second connector 5, the first connector 4 generates an abutting force on the connecting pipe 54, overcomes the elastic force of the elastic member 56 and drives the connecting pipe 54 to move downward. At this time, the ventilation notch 541 on the side wall of the connecting pipe 54 is exposed and communicated with the ventilation cavity 51. The steam generated by the steam generator 3 can sequentially pass through the first channel 52, the ventilation cavity 51, the ventilation notch 541, the connecting pipe 54, and the second channel 53 and enter the first connector 4. When the user picks up the kettle body 2 and pulls it away from the first connector 4, the first connector 4 no longer exerts an abutting force on the connecting pipe 54, and the elastic member 56 resets, driving the connecting pipe 54 to move upward until the seal 55 at the other end of the connecting pipe 54 seals the port of the second channel 53, so that the steam cannot spray out from the second connector 5.

[0106] It can be seen that by arranging such a steam anti-spray structure in the second connector 5, it effectively avoids the situation of steam spraying out from the second connector 5 when the user pulls away the first connector 4, greatly improves the user experience, eliminates the potential safety hazard that the user may be scalded by high-temperature steam, and improves the safety of the product. At the same time, the structure is ingeniously designed. Through the cooperation of the simple connecting pipe 54, the elastic member 56 and the seal 55, the effective control of steam spraying is realized. The structure is relatively simple, the cost is low and the reliability is high, which is beneficial to the large-scale production and promotion of the product.

[0107] Specifically, the elastic member 56 can be specifically a spring or other elastic workpieces, such as rubber, elastic washers, etc.

It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
