Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, specifically to an electric steamer. Background Technology

[0002] An electric steamer is a kitchen appliance that uses electric heating to directly steam various foods. It is mainly used in homes, restaurants, canteens, and other establishments for steaming or stewing food. It can also be used to quickly heat rice and other dishes, making it a versatile cooking tool that is increasingly popular.

[0003] Electric steamers cook food by heating water to boiling to produce high-temperature steam. The high-temperature steam cannot be trapped inside the electric steamer indefinitely, otherwise it will cause high pressure inside the pot and push open the steaming lid. Therefore, the steam must be released to the outside. Generally, there is a steam hole on the top of the steaming lid, through which the high-temperature steam will be released to the outside.

[0004] However, when high-temperature steam is discharged from the steam vent to the outside, the following problems will occur: On the one hand, the high-temperature steam discharged from the steam vent will spread in all directions. Since the temperature inside the kitchen is lower than the temperature of the steam, the steam will liquefy into water and adhere to the kitchen walls and countertops, making the walls and countertops wet and difficult to clean, thus affecting kitchen hygiene; on the other hand, if users accidentally touch the steam, they will be burned, posing a safety hazard. Summary of the Invention

[0005] In view of this, the present invention provides an electric steamer to solve the problem that existing electric steamers emit high-temperature steam, which affects kitchen hygiene and poses safety hazards.

[0006] This invention provides an electric steamer, comprising:

[0007] A base, wherein the base is provided with a water-holding space;

[0008] A steaming lid is positioned above the base, and the steaming lid has steam holes, forming a steaming space between the steaming lid and the base;

[0009] A water tank is provided on the base and located on one side of the steaming lid. The water tank has a first through hole and is adapted to add water to the water-holding space.

[0010] A pipe is provided on the water tank. The pipe includes a hollow section that extends through both ends. The hollow section is connected to the first through hole. The first end of the pipe is rotatably connected to the water tank at the first through hole, and the second end is in a first state that is connected to the steam hole.

[0011] Beneficial effects: By setting the electric steamer to include a water tank with a pipe installed on it, the first end of the pipe is rotatably connected to the water tank, and the second end is in a first state connected to the steam hole. This allows the high-temperature steam generated during the operation of the electric steamer to flow out of the steam hole and into the second end of the pipe, and then into the water tank through the hollow part of the pipe, the first end, and the first through hole. On the one hand, this avoids the problems of high-temperature steam venting outward, which may affect kitchen hygiene and pose safety hazards. On the other hand, the high-temperature steam can be guided into the water tank, cooled into condensate, and reused, thus realizing the recycling and reuse of high-temperature steam.

[0012] In one optional embodiment, the water tank is provided with a first mating structure, which is located outside the first through hole and is rotatably connected to the first end of the pipe.

[0013] In one optional implementation, the first mating structure includes:

[0014] A first mating part is provided at the first through hole, and the first mating part is hollow.

[0015] The second mating part is spaced apart on the outside of the first mating part, and the first end of the pipe is located between the first mating part and the second mating part, and is adapted to rotate relative to the first mating part and the second mating part.

[0016] Beneficial effects: By setting the first mating structure to include a first mating part and a second mating part, it is possible to ensure that the first end of the pipe can rotate relative to the water tank while ensuring that the first through hole is connected to the first end of the pipe. The structure is relatively simple.

[0017] In one optional embodiment, the second mating part is provided with a first limiting structure, and the pipe is provided with a second limiting structure corresponding to the first limiting structure near the first end. The second limiting structure and the first limiting structure are adapted to restrict the first end from disengaging from the first mating structure.

[0018] Beneficial effects: By setting a first limiting structure on the second mating part and a second limiting structure that mates with the first limiting structure on the pipeline, the first limiting structure and the second limiting structure can limit the first end of the pipeline, preventing the first end of the pipeline from coming off when it rotates from the first mating structure, thus ensuring the stability of the first end of the pipeline when it rotates.

[0019] In one optional embodiment, the first limiting structure is located on the side of the second limiting structure away from the water tank;

[0020] And / or, the first limiting structure and the second limiting structure are raised ribs.

[0021] In one optional embodiment, the steam cover is provided with a third mating structure, which is located outside the steam hole and is adapted to position the second end of the pipe in the first state.

[0022] Beneficial effects: By setting a third fitting structure on the steam cover and placing the third fitting structure outside the steam hole, the second end of the pipe can be positioned when it is rotated toward the steam cover, preventing the second end from not rotating to the steam hole or rotating beyond the steam hole, thus ensuring the connection between the second end of the pipe and the steam hole, allowing high-temperature steam to smoothly enter the pipe.

[0023] In one optional embodiment, the water tank is provided with a second mating structure, and the second end of the pipe has a second state in which it is fixedly connected to the second mating structure.

[0024] Beneficial effects: By setting a second mating structure on the water tank, and having the second end of the pipe in a second state that mates with the mating structure, both ends of the pipe can be fixedly connected to the water tank when the electric steamer is not in operation. When water needs to be added to the water tank, the pipe can be used as a handle, improving the ease of operation.

[0025] In one optional embodiment, the second mating structure is provided with a first positioning structure, and the pipe is provided with a second positioning structure near the second end. The first positioning structure and the second positioning structure are mated and connected, which is suitable for fixing the second mating structure and the pipe in the second state.

[0026] In one optional embodiment, the first positioning structure is a positioning hole, and the second positioning structure is a positioning post;

[0027] And / or, the second mating structure is a baffle.

[0028] In one alternative embodiment, the pipe has a U-shaped structure;

[0029] And / or, the water tank is provided with a water inlet, and the water inlet is provided with a water cap.

[0030] In one optional embodiment, the water tank is provided with a water outlet structure, and the water in the water tank is adapted to be added to the water-holding space through the water outlet structure.

[0031] Beneficial effect: By setting a water outlet structure at the bottom of the water tank, it is easy to add water from the water tank to the water-filling space of the base.

[0032] In one optional embodiment, the base is provided with an opening structure corresponding to the water outlet structure;

[0033] The water outlet structure includes:

[0034] The water outlet body is fixedly connected to the water tank, and the water outlet body is provided with a water outlet.

[0035] A blocking structure is movably disposed at the water outlet, adapted to allow the opening structure to abut against the blocking structure when the water tank is placed on the base, so that the blocking structure has a water-discharging state with the water outlet open; and when the water tank is separated from the base, the opening structure moves away from the blocking structure, so that the blocking structure has a closed state with the water outlet blocked.

[0036] Beneficial effects: By setting an opening structure on the base, the water outlet structure includes a water outlet body and a sealing structure. When the water tank is placed on the base, the opening structure can push the sealing structure away from the water outlet, allowing water from the tank to be added to the water-holding space of the base through the water outlet structure. When the water tank is removed from the base, the sealing structure can automatically fall back to the water outlet by gravity to seal the water outlet, allowing the user to add water to the tank.

[0037] In one optional embodiment, the sealing structure includes:

[0038] The sealing body is movable at the water outlet.

[0039] A sealing part is provided at the end of the sealing body away from the base, and the size of the sealing part is larger than the water outlet;

[0040] A connecting part is provided at one end of the sealing body near the base, and is adapted to abut against the opening structure when the water is flowing out.

[0041] In one optional embodiment, the water outlet body is provided with a partition structure near the water outlet, the partition structure is provided with a water outlet channel, and the sealing body is movably disposed within the water outlet channel.

[0042] In one optional embodiment, the water outlet structure includes:

[0043] An elastic element is provided on the outside of the sealing body, with one end of the elastic element fixedly connected to the partition structure and the other end fixedly connected to the connecting part.

[0044] Beneficial effects: By setting an elastic element on the outside of the sealing body, the sealing part can automatically seal the water outlet under the elastic force of the elastic element. This allows the water outlet structure to be set at any position where it connects to the base of the water tank, improving adaptability.

[0045] In one optional implementation, the opening structure is a protruding post;

[0046] And / or, the water outlet structure includes a receiving structure located at the end of the water outlet body away from the water outlet, the size of the receiving structure being larger than the size of the water outlet, the receiving structure having a water outlet hole, the size of the water outlet hole being smaller than the size of the water outlet, and the water outlet hole communicating with the base.

[0047] Beneficial effects: The water outlet structure includes a receiving structure with a water outlet hole. The size of the receiving structure is larger than the size of the water outlet, while the size of the water outlet hole is smaller than the size of the water outlet. This allows the water flowing out of the water outlet to be buffered by the receiving structure and then flow out slowly from the water outlet hole, preventing excessive water flow when the water in the tank flows towards the base.

Detailed Implementation

[0058] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] Electric steamers cook food by heating water to boiling to produce high-temperature steam. However, because users sometimes need to open the lid to observe the cooking process while steaming dishes, the lid of an electric steamer cannot be sealed. Therefore, it cannot solve the problem of steam overflow by using a high-pressure sealed lid like rice cookers or pressure cookers.

[0060] However, the high-temperature steam in an electric steamer cannot be trapped inside the steamer indefinitely, otherwise it will cause high pressure inside the steamer, which will push the lid open. Therefore, the steam must be released to the outside. Generally, a steam hole is set on the top of the steam lid, and the high-temperature steam will be released to the outside through the steam hole.

[0061] However, when high-temperature steam is discharged from the steam vent to the outside, the following problems will occur: On the one hand, the high-temperature steam discharged from the steam vent will spread in all directions. Since the temperature inside the kitchen is lower than the temperature of the steam, the steam will liquefy into water and adhere to the walls and countertops of the kitchen, making the walls and countertops wet and difficult to clean; on the other hand, if the user accidentally touches the steam, he / she will be burned, which poses a safety hazard.

[0062] Electric steamers in related technologies are equipped with water tanks to facilitate the addition of water to the water-filled space on the base of the electric steamer. Based on this, the applicant of this application proposes an electric steamer to solve the problem caused by steam exhaust in existing electric steamers.

[0063] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0064] According to an embodiment of the present invention, an electric steamer is provided, comprising: a base 1, on which a water-holding space is provided; a steaming lid 2, disposed above the base 1, the steaming lid 2 having a steam hole 201, the steaming lid 2 and the base 1 forming a steaming space; a water tank 3, disposed on the base 1, located on one side of the steaming lid 2, the water tank 3 having a first through hole 301, the water tank 3 being adapted to add water to the water-holding space; and a pipe 4, disposed on the water tank 3, the pipe 4 including a hollow portion 401 extending through both ends, the hollow portion 401 communicating with the first through hole 301, the first end 402 of the pipe 4 being rotatably connected to the water tank 3 at the first through hole 301, and the second end 403 having a first state communicating with the steam hole 201.

[0065] By configuring the electric steamer to include a water tank 3, and a pipe 4 on the water tank 3, with the first end 402 of the pipe 4 rotatably connected to the water tank 3 and the second end 403 having a first state of communication with the steam hole 201, the high-temperature steam generated during the operation of the electric steamer can flow out from the steam hole 201 and enter the second end 403 of the pipe 4, and then enter the water tank 3 through the hollow part 401, the first end 402 and the first through hole 301 of the pipe 4. On the one hand, this avoids the problem of high-temperature steam venting outwards affecting kitchen hygiene and posing safety hazards. On the other hand, the high-temperature steam can be guided into the water tank 3, cooled into condensate and reused, realizing the recycling and reuse of high-temperature steam.

[0066] The electric steamer includes a steaming rack 5, which is located between the steaming lid 2 and the base 1. The rack on the steaming rack 5 is placed in the steaming and stewing space. The rack on the steaming rack 5 can be set with multiple layers so that the electric steamer can steam and stew multiple foods at the same time, thereby improving the utilization rate of the electric steamer.

[0067] like Figure 1 As shown, in this embodiment, the pipe 4 has a U-shaped structure, which facilitates the alignment of the first end 402 of the pipe 4 with the first through hole 301 and the second end 403 with the steam hole 201. As an alternative implementation, the pipe 4 can also have an L-shaped structure.

[0068] In order to achieve a rotatable connection between the water tank 3 and the first end 402 of the pipe 4, the water tank 3 in this embodiment is provided with a first mating structure 6. The first mating structure 6 is located on the outside of the first through hole 301 and is rotatably connected to the first end 402 of the pipe 4.

[0069] The first mating structure 6 has many specific forms, such as Figure 4As shown, the first mating structure 6 in this embodiment includes: a first mating part 601, disposed at the first through hole 301, and the first mating part 601 is hollow; a second mating part 602, spaced apart on the outside of the first mating part 601; and the first end 402 of the pipe 4, disposed between the first mating part 601 and the second mating part 602, suitable for rotation relative to the first mating part 601 and the second mating part 602. By setting the first mating structure 6 to include the first mating part 601 and the second mating part 602, the first end 402 of the pipe 4 can rotate relative to the water tank 3 while ensuring communication between the first through hole 301 and the first end 402 of the pipe 4, resulting in a relatively simple structure.

[0070] As an alternative implementation, the first mating structure 6 can be hinged to the first end 402 of the pipe 4 to achieve a rotatable connection. Specifically, the first mating structure 6 may include a first mating part, which is fixedly connected to the outside of the first through hole 301. The first mating part is provided with a first connecting hole. A second mating part is provided on the outside of the pipe 4 near the first end 402. The second mating part is provided with a second connecting hole. A pin passes through the first connecting hole and the second connecting hole to achieve a rotatable connection between the pipe 4 and the first mating structure 6.

[0071] Specifically, such as Figure 4 As shown, the first mating part 601 and the second mating part 602 are hollow protruding pillars, which are located on the top of the water tank 3. The first end 402 of the pipe 4 is located between the two protruding pillars and can rotate relative to the two protruding pillars.

[0072] In actual production, the first mating part 601 and the second mating part 602 can be integrally formed on the top of the shell of the water tank 3, and the first through hole 301 can be directly formed on the end of the first mating part 601. Alternatively, the first mating part 601, the second mating part 602 and the shell of the water tank 3 can be set separately and assembled into a whole by a fixing structure.

[0073] The second mating part 602 is provided with a first limiting structure 6021, and the pipe 4 is provided with a second limiting structure 404 that is configured to cooperate with the first limiting structure 6021 near the first end 402. The second limiting structure 404 cooperates with the first limiting structure 6021 to restrict the first end 402 of the pipe 4 from disengaging from the first mating structure 6021.

[0074] By providing a first limiting structure 6021 on the second mating part 602, and providing a second limiting structure 404 on the pipe 4 that cooperates with the first limiting structure 6021, the cooperation of the first limiting structure 6021 and the second limiting structure 404 can limit the first end 402 of the pipe 4, preventing the first end 402 of the pipe 4 from coming off when it rotates from the first mating structure 602, thus ensuring the stability of the first end 402 of the pipe 4 when it rotates.

[0075] It should be noted that in other embodiments, the second mating part 602 may not be provided with the first limiting structure 6021, and the pipe 4 may not be provided with the second limiting structure 404. Instead, the stability of the connection between the pipe 4 and the second mating part 602 is achieved by relying on the friction between the second mating part 602 and the pipe 4. When the pipe 4 is rotated by an external force, the pipe 4 can be rotated relative to the second mating part 602 and the first mating part 601.

[0076] Specifically, the first limiting structure 6021 is located on the side of the second limiting structure 404 away from the water tank 3, and both the first limiting structure 6021 and the second limiting structure 404 are raised ribs. As an alternative implementation, the first limiting structure 6021 and the second limiting structure 404 can be a protrusion and a groove, respectively, with both the protrusion and the groove arranged in a ring. The protrusion is inserted into the groove and can rotate relative to the groove, thus not affecting the rotation of the pipe 4 relative to the first mating structure 6.

[0077] like Figure 4 and Figure 5 As shown, the first limiting structure 6021 is an annular first protrusion formed on the inner wall of the second mating part 602 and located on the upper side. The second limiting structure 404 is an annular second protrusion formed on the outer wall of the pipe 4 and located on the lower side. The pipe 4 is limited by the lower end face of the first protrusion on the upper side abutting against the upper end face of the second protrusion on the lower side, but this does not affect the rotation of the pipe 4 relative to the first mating structure 6.

[0078] In other embodiments, the first and second ribs may also be non-circular, but rather multiple ribs may be spaced apart circumferentially.

[0079] like Figure 2 As shown, the steam cover 2 is provided with a third fitting structure 7, which is located outside the steam hole 201. The third fitting structure 7 is adapted to position the second end 403 of the pipe 4 in the first state. Specifically, the third fitting structure 7 is a baffle.

[0080] By setting a third mating structure 7 on the steam cover 2, and the third mating structure 7 being located outside the steam hole 201, the second end 403 of the pipe 4 can be positioned when the second end 403 of the pipe 4 is rotated onto the steam cover 2, preventing the second end 403 from not rotating to the steam hole 201 or rotating beyond the steam hole 201, thus ensuring the connection between the second end 403 of the pipe 4 and the steam hole 201, so that high-temperature steam can smoothly enter the pipe 4.

[0081] Since the cross-section of pipe 4 is circular, the third mating structure 7 can be set as an arc-shaped baffle to facilitate contact with pipe 4. As an alternative implementation, the third mating structure 7 can also be a square baffle.

[0082] Since the pipe 4 has a U-shaped structure, the part where the first end 402 and the second end 403 of the pipe 4 are located is a vertical structure. When the second end 403 of the pipe 4 is rotated to abut against the third mating structure 7, the hollow part 401 of the pipe 4 is aligned with the steam hole 201 through the second end 403. This makes it easy for high-temperature steam to directly enter the hollow part 401 of the pipe 4 from the steam hole 201.

[0083] Of course, in other embodiments, in order to prevent the second end 403 of the pipe 4 from not being aligned with the steam hole 201 and the high temperature steam from pushing the pipe 4 away from the steam hole 201, a positioning hole can also be provided on the third mating structure 7, and a positioning post can be provided near the second end 403 of the pipe 4. The fixed connection between the pipe 4 and the third mating structure 7 can be achieved by inserting the positioning post into the positioning hole.

[0084] like Figure 2 As shown, in this embodiment, the water tank 3 is provided with a second mating structure 8, and the second end 403 of the pipe 4 has a second state that is fixedly connected to the second mating structure 8. By providing the second mating structure 8 on the water tank 3, and having the second end 403 of the pipe 4 in a second state that is mated and connected to the mating structure, both ends of the pipe 4 can be fixedly connected to the water tank 3 when the electric steamer is not in operation. When water needs to be added to the water tank 3, the pipe 4 can be used as a handle, improving operational convenience.

[0085] It should be noted that in other embodiments, the water tank 3 is not provided with a second mating structure 8, and the second end 403 of the pipe 4 is freely positioned when the electric steamer is not in operation.

[0086] The second mating structure 8 is provided with a first positioning structure 801, and the pipe 4 is provided with a second positioning structure 405 near the second end 403. The first positioning structure 801 and the second positioning structure 405 are mated and connected, which is suitable for fixing the second mating structure 8 and the pipe 4 in the second state.

[0087] Specifically, such as Figure 2 and Figure 3 As shown, the first positioning structure 801 is a positioning hole, and the second positioning structure 405 is a positioning post. Alternatively, the first positioning structure 801 can be a positioning post, and the second positioning structure 405 can be a positioning hole. Another possible implementation is that the first positioning structure 801 and the second positioning structure 405 can be a snap-fit ​​and a slot, respectively, achieving a fixed connection between the pipe 4 and the second mating structure 8 through a snap-fit ​​connection.

[0088] The second mating structure 8 can also play a certain positioning role in the rotation of the pipe 4. When the second end 403 of the pipe 4 rotates to abut against the second mating structure 8, the positioning pin is just inserted into the positioning hole, preventing the second end 403 of the pipe 4 from not rotating into place, and ensuring the fixed connection between the pipe 4 and the second mating structure 8 in the second state.

[0089] Similar to the third mating structure 7, the second mating structure 8 in this embodiment is a baffle.

[0090] Similarly, since the cross-section of pipe 4 is circular, the second mating structure 8 can be set as an arc-shaped baffle to facilitate contact with pipe 4. As an alternative implementation, the second mating structure 8 can also be a square baffle.

[0091] like Figure 4 As shown, in this embodiment, the water tank 3 is provided with a water inlet 9, and a water inlet cap 10 is provided on the water inlet 9. When the water inlet cap 10 is provided on the water inlet 9, it can prevent dust from entering the water tank 3. When the water inlet cap 10 is separated from the water inlet 9, water can be added to the water tank 3 through the water inlet 9. As an alternative implementation, the water tank 3 may not have a separate water inlet 9, but instead a second through hole is provided on the inner side of the second mating structure 8, through which water is added to the water tank 3.

[0092] Specifically, the outer wall of the water inlet 9 is threaded, and the inner wall of the water inlet cap 10 is threaded. The water inlet cap 10 is connected to the water inlet 9 via the threads, so that the water inlet cap 10 can be screwed onto the water inlet 9, or the water inlet cap 10 can be screwed off from the water inlet 9. As an alternative implementation, the water inlet cap 10 can also be a cylindrical structure, which can be used to seal the water inlet 9 by being inserted into it, and to open the water inlet 9 by pulling it out.

[0093] Both the water inlet 9 and the pipe 4 are located at the top of the water tank 3, with the water inlet 9 positioned below the horizontal structure of the pipe 4. This arrangement allows for a more compact configuration of the various structures on the water tank 3, and the water inlet 9 is spaced apart from the horizontal structure of the pipe 4, ensuring that the pipe 4 does not interfere with the addition of water to the water inlet 9. Alternatively, the water inlet 9 can be located on the side of the water tank 3.

[0094] When the second end 403 of pipe 4 is engaged with water tank 3, that is, when the second end 403 of pipe 4 is in the position of... Figure 2In the second state shown, the second end 403 of pipe 4 is located at the second mating structure 8 of water tank 3, and the positioning post on it mates with the positioning hole on the second mating structure 8. At this time, pipe 4 can be used as a handle to lift water tank 3 away from base 1, and then the water inlet cap 10 can be rotated and unscrewed to add water to water tank 3 through the water inlet 9. After adding water, water tank 3 is placed on base 1. When the electric steamer needs to work, the second end 403 of pipe 4 can be rotated to the position of the third mating structure 7, that is, the second end 403 of pipe 4 is in the position shown... Figure 3 In the first state shown, due to the positioning effect of the third mating structure 7, the hollow part 401 of the second end 403 of the pipe 4 is aligned with the steam hole 201 next to the third mating structure 7. At this time, the electric steamer continuously generates high-temperature steam. The high-temperature steam will enter the hollow part 401 of the pipe 4 through the steam hole 201 of the steam cover 2, and then enter the water tank 3 through the hollow part 401 of the pipe 4. When the high-temperature steam encounters the water inside the water tank 3, it will cool and liquefy into water, realizing the recycling and reuse of high-temperature steam.

[0095] like Figure 4 As shown, the water tank 3 in this embodiment is provided with a water outlet structure 11, and the water in the water tank 3 is suitable for being added to the water-holding space through the water outlet structure 11. By providing the water outlet structure 11 at the bottom of the water tank 3, it is convenient to add water from the water tank 3 to the water-holding space of the base 1.

[0096] The water outlet structure 11 is located at the bottom of the water tank 3. Alternatively, the water outlet structure 11 can be located at any position where the water tank 3 connects to the base 1.

[0097] like Figure 7 As shown, in this embodiment, the base 1 is provided with an opening structure 101 corresponding to the water outlet structure 11; as Figure 6 As shown, the water outlet structure 11 includes: a water outlet body 1101, fixedly connected to the water tank 3, with a water outlet 11011 on the water outlet body 1101; and a sealing structure, movably disposed at the water outlet 11011, adapted to allow the opening structure 101 to abut against the sealing structure when the water tank 3 is placed on the base 1, so that the sealing structure has an open water outlet 11011 water outlet state; and when the water tank 3 is separated from the base 1, the opening structure 101 moves away from the sealing structure, so that the sealing structure has a closed water outlet 11011 sealed state. Specifically, the opening structure 101 is a protruding post.

[0098] By setting an opening structure 101 on the base 1, the water outlet structure 11 includes a water outlet body 1101 and a sealing structure. When the water tank 3 is placed on the base 1, the opening structure 101 can push the sealing structure away from the water outlet 11011, so that the water in the water tank 3 can be added to the water-holding space of the base 1 through the water outlet structure 11. When the water tank 3 is removed from the base 1, the sealing structure can automatically fall to the water outlet 11011 by gravity to seal the water outlet 11011, so that the user can add water to the water tank 3.

[0099] It should be noted that in other embodiments, the water outlet structure 11 can be in the form of a water outlet combined with a water outlet cover. In this case, the water outlet cover is located on the outside of the water tank 3. When water needs to be added to the water tank 3, the water outlet cover is connected to the water outlet. When water needs to be added from the water tank 3 to the base 1, the water outlet cover is separated from the water outlet. The specific connection method between the water outlet and the water outlet cover can be referred to the connection between the water inlet 9 and the water inlet cover 10, and will not be described again here.

[0100] like Figure 6 As shown, the sealing structure includes: a sealing body 1102, which is movably disposed at the outlet 11011; a sealing part 1103, which is disposed at the end of the sealing body 1102 away from the base 1, and the size of the sealing part 1103 is larger than that of the outlet 11011; and a connecting part 1104, which is disposed at the end of the sealing body 1102 close to the base 1 and is adapted to abut against the opening structure 101 when the water is flowing out.

[0101] Specifically, the sealing body 1102 is a valve body with a relatively long length, the sealing part 1103 is a valve core with a relatively wide width, and the width of the connecting part 1104 is slightly larger than the width of the valve body. Here, "length" refers to... Figure 6 The dimensions in the top and bottom directions, the width refers to Figure 6 The dimensions in the left and right directions.

[0102] In this embodiment, the water outlet body 1101 is provided with a partition structure 1105 near the water outlet 11011, the partition structure 1105 is provided with a water outlet channel, and a sealing body 1102 is movably provided in the water outlet channel.

[0103] like Figure 6 and Figure 7 As shown, the water outlet 11011 is located at the upper end of the water outlet body 1101. The partition structure 1105 is a partition plate located inside the water outlet body 1101, near the upper end. The partition plate has a water outlet channel in the middle, which is the water outlet through hole.

[0104] The water outlet structure 11 in this embodiment includes an elastic element 1106. The elastic element 1106 is disposed on the outside of the sealing body 1102. One end of the elastic element 1106 is fixedly connected to the partition structure 1105, and the other end is fixedly connected to the connecting part 1104. Specifically, the elastic element 1106 is a spring. By providing the elastic element 1106 on the outside of the sealing body 1102, the sealing part 1103 can automatically seal the water outlet 11011 under the elastic force of the elastic element 1106. This allows the water outlet structure 11 to be placed at any position where the water tank 3 is connected to the base 1, improving adaptability.

[0105] Of course, if the water outlet structure 11 is located at the lowest end of the water tank 3 and the water flows from top to bottom, the elastic element 1106 may not be provided. Instead, when the water tank 3 is separated from the base 1, the sealing body 1102 moves downward by gravity so that the sealing part 1103 seals the water outlet 11011.

[0106] like Figure 6 and Figure 7 As shown, the water outlet structure 11 includes a receiving structure 1107, which is located at the end of the water outlet body 1101 away from the water outlet 11011. The size of the receiving structure 1107 is larger than the size of the water outlet 11011. The receiving structure 1107 is provided with a water outlet hole 11071, which is smaller than the size of the water outlet 11011. The water outlet hole 11071 is connected to the base 1.

[0107] The water outlet structure 11 includes a receiving structure 1107, on which a water outlet hole 11071 is provided. The size of the receiving structure 1107 is larger than the size of the water outlet 11011, and the size of the water outlet hole 11071 is smaller than the size of the water outlet 11011. In this way, the water flowing out of the water outlet 11011 can be buffered by the receiving structure 1107 and then slowly flow out of the water outlet hole 11071, preventing the water in the water tank 3 from flowing to the base 1 with too large a flow.

[0108] Specifically, the receiving structure 1107 is a rubber stopper, and multiple water outlet holes 11071 are evenly provided on the rubber stopper along the circumference.

[0109] like Figure 6 As shown, a sealing device 1108 is provided at the connection between the water outlet body 1101 and the water tank 3, and a sealing device 1108 is provided between the receiving structure 1107 and the water outlet body 1101, which can play a certain sealing role. Specifically, the sealing device 1108 is a sealing ring.

[0110] When water tank 3 is placed on base 1, as Figure 7As shown, the opening structure 101 on the base 1 moves upward against the receiving structure 1107, and the receiving structure 1107 moves upward against the sealing body 1102, compressing the spring, which in turn drives the sealing part 1103 to move upward. At this time, the sealing part 1103 moves away from the water outlet 11011, and the water outlet 11011 is not blocked and is in the open state. The water in the water tank 3 can flow downward from the water outlet 11011 into the receiving structure 1107, and then flow into the water-holding space of the base 1 through the water outlet hole 11071 on the receiving structure 1107, so that the electric steamer can work.

[0111] When water tank 3 is lifted out, that is, when water tank 3 separates from base 1, as follows Figure 6 As shown, due to the elastic force of the spring and the force of gravity, a downward force is exerted on the sealing body 1102, causing the sealing body 1102 to move the sealing part 1103 downward, blocking the water outlet 11011, and the water in the water tank 3 cannot flow down.

[0112] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
