Description

Technical Field

[0001] The present application belongs to the technical field of handles, and specifically relates to a cover body and an electrical device. Background Art

[0002] As people's living standards continue to improve, electrical appliances have entered thousands of households. Some electrical appliances need to heat liquids and / or food materials, and steam is generated during the heating process.

[0003] In the prior art, during the heating and boiling process, steam is directly discharged from the steam outlet, which may result in excessive steam being discharged, which may easily scald the user, posing a major safety hazard and reducing the user experience. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a cover body and an electrical device, which aims to at least solve the technical problem of excessive amount of steam discharged, which may easily scald users, to a certain extent.

[0005] The technical solution of the present invention is:

[0006] A cover body is special in that it includes: a shell body, which is provided with a steam inlet hole and a steam exhaust hole; an air flow channel, which connects the steam inlet hole and the steam exhaust hole, and the air flow channel includes multiple air flow segments, and along the exhaust direction, the bottom height of at least one of the air flow segments gradually decreases.

[0007] Since the shell is provided with a steam inlet hole and a steam exhaust hole, and the air flow channel connects the steam inlet hole and the steam exhaust hole, the steam can enter the air flow channel through the steam inlet hole, and the flow distance of the steam can be increased through the exhaust channel, thereby extending the exhaust path. The steam can be fully condensed in the air flow channel, so that part of the steam is condensed into water droplets, reducing the amount of steam discharged externally. At the same time, the temperature of another part of the steam can be lowered, thereby reducing the amount of steam ejected from the exhaust hole and lowering the steam temperature, effectively eliminating the safety hazard of steam scalding people and improving the user experience. Since the air flow channel includes multiple air flow sections, the bottom height of at least one air flow section gradually decreases along the exhaust direction, so the exhaust path can be further extended, the exhaust time can be extended, and the steam can be fully condensed in the air flow section.

[0008] In some embodiments, the bottom height of at least one of the air flow sections gradually increases to facilitate the condensed water to flow into the heating chamber of the electrical device through the steam inlet hole.

[0009] In some embodiments, the number of the airflow sections with gradually increasing bottom heights is greater than the number of the airflow sections with gradually decreasing bottom heights, so as to further increase the resistance to steam flow.

[0010] In some embodiments, the steam inlet hole and the steam exhaust hole are respectively located at two ends of the air flow channel and are staggered to avoid direct exhaust of steam.

[0011] In some embodiments, the steam inlet hole is lower than the lowest point of the airflow channel to facilitate condensed water in the airflow channel to flow into the steam inlet hole, and the steam exhaust hole is higher than the highest point of the airflow channel to facilitate steam exhaust.

[0012] In some embodiments, the cover body also includes: a plurality of enclosures, which are arranged at intervals in the shell and are located between the steam inlet and the steam exhaust hole, and the airflow segments are formed between every two adjacent enclosures and between the shell and adjacent enclosures, respectively. The two airflow segments on both sides of the same enclosure are connected, and the steam inlet and the steam exhaust hole are connected to different airflow segments respectively to extend the exhaust path.

[0013] In some embodiments, the enclosure is spaced apart from the bottom of the shell to avoid water accumulation in the airflow section where the bottom height gradually decreases.

[0014] In some embodiments, the two outermost shells among the multiple shells are connected by a connector, and the distance between the connector and the inner wall of the shell is greater than the distance between the outermost shell and the shell, so that a accommodating cavity is formed between the connector and the shell, and the accommodating cavity is connected to the steam exhaust hole to increase the space for accommodating condensed water.

[0015] In some embodiments, the number of the airflow channels is two, and the two airflow channels are symmetrically arranged to further increase the flow distance of the steam.

[0016] In some embodiments, the air flow sections corresponding to the two air flow channels are connected to form a ring structure to ensure that steam can flow into the two air flow channels 30 from the steam inlet hole 101 .

[0017] In some embodiments, a plurality of the airflow segments are sequentially arranged between the steam inlet hole and the steam exhaust hole; wherein, in the exhaust direction, the cross-sectional areas of the plurality of the airflow segments gradually decrease to achieve condensation of steam in the airflow channel 30 .

[0018] In some embodiments, the cover body also includes: a baffle, which is provided on the shell and located in the airflow section connected to the steam inlet hole, the baffle is opposite to the steam inlet hole to increase the resistance to steam flow, the airflow channel has a steam outlet end, and the baffle is located between the steam inlet hole and the steam outlet end to achieve the increase in the resistance to steam flow.

[0019] In some embodiments, the same airflow section has a steam inlet end and a steam outlet end, there is a height difference between the steam inlet end and the steam outlet end, and the airflow section is inclined between the steam inlet end and the steam outlet end to increase the resistance to steam flow.

[0020] In some embodiments, a guide channel connected to the airflow channel is provided in the shell, and the steam inlet hole is located in the guide channel so that water droplets condensed from the steam can return to the heating chamber of the electrical device through the steam inlet hole as much as possible.

[0021] In some embodiments, the cover body also includes: a guide piece, rotatably disposed on the shell, the guide piece and the airflow channel are respectively located on opposite sides of the shell, the guide piece has a guide channel and an airflow inlet connected to the guide channel, and the guide channel is connected to the steam inlet; a counterweight piece, disposed at one end of the guide piece; wherein the airflow inlet is located at an end of the guide piece away from the counterweight piece, so as to prevent condensed water from flowing out of the steam inlet 101 when the cover body is flipped over.

[0022] Based on the same inventive concept, the present invention further provides an electrical device, comprising a cover body and the cover body, wherein the housing is arranged in the cover body.

[0048] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0049] The cover body and electrical equipment provided in this embodiment are intended to at least to a certain extent solve the technical problem of excessive amount of discharged steam, which may easily scald the user.

[0050] Figure 1 It is a schematic diagram of the structure of the cover body of some embodiments; Figure 2 for Figure 1 Schematic diagram of steam flow in the middle cover; Figure 3 for Figure 2 A top view of Figure 4 for Figure 1 A cross-sectional view of the middle cover body. Figure 1 , Figure 2 , Figure 3 and Figure 4 The cover body of the embodiment of the present application includes: a shell 10 and an airflow channel 30. The shell 10 is provided with a steam inlet hole 101 and a steam exhaust hole 102. The airflow channel 30 connects the steam inlet hole 101 and the steam exhaust hole 102, and the airflow channel 30 includes a plurality of airflow segments 301. Along the exhaust direction, the bottom height of at least one airflow segment 301 gradually decreases.

[0051] One of the steam inlet hole 101 and the steam exhaust hole 102 is communicated with one of the plurality of air flow segments 301 , and the other is communicated with one of the remaining air flow segments 301 .

[0052] Since the shell 10 is provided with a steam inlet hole 101 and a steam exhaust hole 102, and the airflow channel 30 connects the steam inlet hole 101 and the steam exhaust hole 102, the steam can enter the airflow channel 30 through the steam inlet hole 101, and the flow distance of the steam can be increased through the airflow channel 30, and the exhaust path can be extended. The steam can be fully condensed in the airflow channel 30, so that part of the steam condenses into water droplets, reducing the amount of steam discharged externally. At the same time, the temperature of another part of the steam can be reduced, thereby reducing the amount of steam ejected from the exhaust hole 102 and lowering the steam temperature, effectively eliminating the safety hazard of steam scalding people and improving the user experience. Since the airflow channel 30 includes multiple airflow sections 301, the bottom height of at least one airflow section 301 gradually decreases along the exhaust direction, so the exhaust path can be further extended, the exhaust time can be extended, and the steam can be fully condensed in the airflow section 301.

[0053] In some embodiments, the steam inlet hole 101 may be located at a middle position of the shell 10 . Of course, in other embodiments, the steam inlet hole 101 may also be located at a non-middle position of the shell 10 .

[0054] In some embodiments, the steam exhaust hole 102 may be directly connected to the outside, or may be connected to the heating chamber of the electrical device, or may be connected between the heating chamber of the electrical device and the housing of the electrical device.

[0055] In some embodiments, when the exhaust hole 102 is connected to the heating chamber of the electrical device, when the air pressure in the heating chamber of the electrical device increases, the pressure relief component of the electrical device can relieve pressure to ensure the safety of the heating chamber of the electrical device.

[0056] In some embodiments, when the exhaust hole 102 is connected to the heating chamber of the electrical device and the outer casing of the electrical device, the thermostat can be triggered to detect the temperature of the exhaust steam. When the temperature reaches the set requirement, the controller of the electrical device can control the heating component of the electrical device to reduce the heating power for insulation.

[0057] In some embodiments, in order to increase the resistance to steam flow and facilitate the condensed water to flow into the heating chamber of the electrical equipment through the steam inlet, the bottom height of at least one air flow segment 301 is gradually increased, so that the steam flow speed is slowed down, and the time that the steam stays in the air flow segment 301 with the gradually increasing bottom height is increased to facilitate the condensation of steam into water droplets. At the same time, under the action of gravity, the water droplets condensed from the steam will flow along the air flow segment 301 toward the steam inlet 101 until they flow into the heating chamber of the electrical equipment, thereby avoiding excessive condensation of water droplets in the shell 10 and leakage of condensed water droplets, further improving the user experience and reducing the waste of water resources. At the same time, the resistance to steam flow is increased, the steam flow speed is reduced, and the time that the steam stays in the air flow segment 301 can be extended so that the steam can have sufficient time to condense in the air flow segment 301.

[0058] In some embodiments, in order to further increase the resistance to steam flow, the number of airflow segments 301 with gradually increasing bottom heights is greater than the number of airflow segments 301 with gradually decreasing bottom heights. The airflow segments 301 with gradually increasing bottom heights can slow down the speed of steam flow and increase the time that steam stays in the airflow segments 301 with gradually increasing bottom heights, so that the steam condenses into water droplets. The number of airflow segments 301 with gradually increasing bottom heights can be one more than the number of airflow segments 301 with gradually decreasing bottom heights.

[0059] In some embodiments, the bottom height of at least one airflow segment 301 gradually decreases and the bottom height of at least one airflow segment 301 gradually increases, thereby achieving a staggered arrangement, increasing the resistance to steam flow, and reducing the steam flow speed. The time that the steam stays in the airflow segment 301 can be extended so that the steam has sufficient time to condense in the airflow segment 301, so that part of the steam condenses into water droplets, reducing the amount of steam discharged externally. At the same time, another part of the steam can have sufficient time to cool down in the airflow segment 301, and the temperature of the other part of the steam can be reduced, thereby reducing the amount of steam ejected from the exhaust hole 102 and reducing the steam temperature, effectively eliminating the safety hazard of steam scalding people and improving the user experience.

[0060] In some embodiments, in order to ensure the residence time of steam in the airflow channel 30, the steam inlet 101 and the steam exhaust hole 102 are respectively located at the two ends of the airflow channel 30. The steam enters the airflow channel 30 through the steam inlet 101 and is then discharged from the steam exhaust hole 102, so that the steam can be fully condensed in the airflow channel 30 to reduce the amount of steam discharged externally.

[0061] In some embodiments, in order to prevent direct discharge of steam, the steam inlet hole 101 and the steam exhaust hole 102 are staggered, that is, the steam inlet hole 101 and the steam exhaust hole 102 are not coaxial, and the steam entering the air flow channel 30 through the steam inlet hole 101 will not be directly discharged from the steam exhaust hole 102, thereby ensuring the residence time of the steam in the air flow channel 30.

[0062] In some embodiments, in order to facilitate the condensed water in the airflow section 301 to flow into the steam inlet 101, the steam inlet 101 is lower than the lowest point of the airflow section 301. Under the action of gravity, the water droplets condensed from the steam will flow along the airflow section 301 toward the steam inlet 101 until they flow into the heating chamber of the electrical equipment, thereby avoiding excessive condensation of water droplets in the shell 10.

[0063] In some embodiments, in order to facilitate the discharge of steam, the exhaust hole 102 is higher than the highest point of the airflow section 301. At the same time, condensed water is prevented from being discharged from the exhaust hole 102, and the leakage of condensed water is prevented, thereby further improving the user experience.

[0064] In some embodiments, in order to form an airflow segment 301, a plurality of enclosures 20 are arranged at intervals in the shell body 10 and are located between the steam inlet 101 and the steam exhaust hole 102. An airflow segment 301 is formed between every two adjacent enclosures 20 and between the shell body 10 and adjacent enclosures 20. The two airflow segments 301 on both sides of the same enclosure 20 are connected, and the steam inlet 101 and the steam exhaust hole 102 are respectively connected to different airflow segments 301. Therefore, steam can enter the airflow segment 301 through the steam inlet 101. The flow distance of the steam is increased by using a plurality of airflow segments 301, and the exhaust path can be extended. The steam can be fully condensed in the airflow segment 301, so that part of the steam is condensed into water droplets, reducing the amount of steam discharged. At the same time, the temperature of another part of the steam can be reduced, thereby reducing the amount of steam ejected from the steam exhaust hole 102 and reducing the steam temperature, effectively eliminating the safety hazard of steam scalding people and improving the user experience.

[0065] In some embodiments, in order to avoid water accumulation in the airflow section 301 where the bottom height gradually decreases, the enclosure 20 is spaced apart from the bottom of the shell 10, that is, there is a gap between the bottom of the enclosure 20 and the shell 10, so that condensed water in the airflow section 301 where the bottom height gradually decreases can flow into the steam inlet 101 through the gap. Under the action of gravity, water droplets condensed from steam will flow toward the steam inlet 101 until they flow into the heating chamber of the electrical equipment, thereby avoiding excessive condensation of water droplets in the shell 10 and leakage of condensed water droplets, further improving the user experience and reducing the waste of water resources. At the same time, the resistance to steam flow is increased, the steam flow speed is reduced, and the time the steam stays in the airflow section 301 can be extended, so that the steam can have sufficient time to condense in the airflow section 301.

[0066] In some embodiments, when heating food, the flow distance of steam can be increased through the airflow section 301, which can guide the steam to condense, thereby retaining the nutrition of the food to the maximum extent and reducing the taste pollution caused by steam emission.

[0067] Combination Figure 1 , Figure 2 and Figure 3 In some embodiments, in order to further extend the exhaust path, two air flow sections 301 on both sides of the same enclosure 20 are concentrically arranged. The cross-sectional shape of the enclosure 20 may be an arc.

[0068] In some embodiments, since the cross-sectional shape of most shells 10 is circular, the two airflow segments 301 on both sides of the same enclosure 20 are concentrically arranged to adapt to the shell 10 to facilitate the assembly of the enclosure 20.

[0069] Combination Figure 1 , Figure 2 and Figure 3 In some embodiments, in order to further extend the exhaust path, multiple enclosures 20 are spaced in sequence from the middle of the shell body 10 to the edge of the shell body 10, and air flow sections 301 are formed between two adjacent enclosures 20 and between the outermost enclosures 20 among the multiple enclosures 20 and the inner wall of the shell body 10, respectively. The air flow sections 301 on both sides of the same enclosure 20 are connected, and one of the innermost air flow section 3011 and the outermost air flow section 3012 is connected to the steam inlet 101, and the other is connected to the steam exhaust hole 102.

[0070] In some embodiments, when the number of airflow segments 301 is three, along the exhaust direction, the bottom height of the innermost airflow segment 3011 gradually increases, the bottom height of the outermost airflow segment 3012 gradually increases, and the bottom height of the airflow segment between the innermost airflow segment 3011 and the outermost airflow segment 3012 gradually decreases.

[0071] In some embodiments, steam can enter one of the innermost airflow segment 3011 and the outermost airflow segment 3012 through the steam inlet 101, and then enter the remaining airflow segments among the multiple airflow segments 301, and finally, be discharged from the other one of the innermost airflow segment 3011 and the outermost airflow segment 3012, which can fully improve the flow distance of the steam and fully extend the exhaust path. The steam can be fully condensed in the airflow segment 301, so that part of the steam condenses into water droplets, reducing the amount of steam discharged. At the same time, the temperature of another part of the steam can be lowered, thereby reducing the amount of steam ejected from the exhaust hole 102 and lowering the steam temperature, effectively eliminating the safety hazard of steam scalding people and improving the user experience.

[0072] In some embodiments, the innermost airflow segment 3011 may be communicated with the steam inlet hole 101, and the outermost airflow segment 3012 may be communicated with the steam exhaust hole 102. Of course, in other embodiments, the outermost airflow segment 3012 may be communicated with the steam inlet hole 101, and the innermost airflow segment 3011 may be communicated with the steam exhaust hole 102.

[0073] Combination Figure 1 , Figure 2 and Figure 3 In some embodiments, in order to further extend the exhaust path, when the innermost air flow segment 3011 can be connected to the steam inlet hole 101 and the outermost air flow segment 3012 can be connected to the exhaust hole 102, the head of the innermost air flow segment 3011 is connected to the steam inlet hole 101, the tail of the innermost air flow segment 3011 is connected to the head of the air flow channel adjacent to the innermost air flow segment 3011, the air flow channels between the innermost air flow segment 3011 and the outermost air flow segment 3012 are connected head to tail in sequence, and the head of the outermost air flow segment 3012 is connected to the outermost air flow segment 3012. The tail ends of the air flow channels adjacent to the air flow segments 3012 are connected, and the tail end of the outermost air flow segment 3012 is connected to the exhaust hole 102, so that the steam can fully flow through each air flow segment 301, which can fully improve the flow distance of the steam. The steam can be fully condensed in the air flow segment 301, so that part of the steam condenses into water droplets, reducing the amount of steam discharged externally. At the same time, the temperature of another part of the steam can be lowered, thereby reducing the amount of steam ejected from the exhaust hole 102 and lowering the steam temperature, effectively eliminating the safety hazard of steam scalding people and improving the user experience.

[0074] Combination Figure 1 , Figure 2 and Figure 3 In some embodiments, in order to increase the space for accommodating condensed water, the two outermost enclosures 20 among the multiple enclosures 20 are connected by a connector 90, and the distance between the connector 90 and the inner wall of the shell 10 is greater than the distance between the outermost enclosure 20 and the shell 10, so that a accommodating chamber 40 is formed between the connector 90 and the shell 10, and the accommodating chamber 40 is connected to the exhaust hole 102. When the steam condenses into water droplets, the water droplets can be fully accommodated by the accommodating chamber 40 to avoid excessive accumulation of water droplets and discharge from the exhaust hole 102, thereby avoiding water droplet leakage, further improving the user experience.

[0075] In some embodiments, when the accommodating chamber 40 is connected to the steam exhaust hole 102, the connecting member 90 is recessed in the direction of the steam inlet hole 101, so that the connecting member 90 and the steam exhaust hole 102 are staggered, so that the accommodating chamber 40 can fully accommodate water droplets condensed from the steam. At the same time, the lower cover 80 of the electrical device is flippably arranged on the main body of the electrical device, and the steam exhaust hole 102 is closer to the flipping position of the lower cover 80 than the steam inlet hole 101. That is to say, when the lower cover 80 is opened, the steam exhaust hole 102 is located below the steam inlet hole 101. Under the action of gravity, the water droplets in the airflow channel 30 will gather at the steam exhaust hole 102. The accommodating chamber 40 can fully accommodate the gathered water droplets to avoid excessive accumulation of water droplets and their discharge from the steam exhaust hole 102, to avoid water droplet leakage, and further improve the user experience.

[0076] In some embodiments, steam enters the accommodating chamber 40 through the airflow channel 30. The flow distance of the steam can be further improved through the accommodating chamber 40, and the exhaust path can be extended. The steam can condense in the accommodating chamber 40, so that part of the steam condenses into water droplets, reducing the amount of steam discharged. At the same time, the temperature of another part of the steam can be lowered, thereby reducing the amount of steam ejected from the exhaust hole 102 and lowering the steam temperature, effectively eliminating the safety hazard of steam scalding people and improving the user experience.

[0077] In some embodiments, in order to further increase the flow distance of the steam, the number of the air flow channels 30 is two, and the two air flow channels 30 are symmetrically arranged. The steam flows through the two air flow channels 30, extending the exhaust path so that the steam can be fully condensed in the two air flow channels 30, so that part of the steam condenses into water droplets, reducing the amount of steam discharged externally. At the same time, another part of the steam can have sufficient time to cool down in the two air flow channels 30, which can reduce the temperature of the other part of the steam, thereby reducing the amount of steam ejected from the exhaust hole 102 and lowering the steam temperature, effectively eliminating the safety hazard of steam scalding people and improving the user experience.

[0078] In some embodiments, in order to ensure that steam can flow into the two air flow channels 30 from the steam inlet 101, the air flow sections 301 corresponding to the two air flow channels 30 are connected to form a ring structure to ensure smooth steam flow and avoid steam leakage.

[0079] In some embodiments, in order to achieve condensation of steam in the airflow channel 30, multiple airflow segments 301 are arranged in sequence between the steam inlet 101 and the steam exhaust hole 102, wherein in the exhaust direction, the cross-sectional areas of the multiple airflow segments 301 gradually become smaller, and when the steam flows into the multiple airflow segments 301, the steam pressure in the multiple airflow segments 301 can be changed to facilitate the condensation of steam in the airflow channel 30 to form water droplets, thereby ensuring the condensation effect.

[0080] In some embodiments, the cross-sectional area of ​​the same airflow segment 301 may gradually decrease along the exhaust direction. Of course, in other embodiments, the cross-sectional area of ​​the same airflow segment 301 is the same, and the cross-sectional area of ​​every two adjacent airflow segments 301 may gradually decrease along the exhaust direction.

[0081] Combination Figure 2 and Figure 3 In some embodiments, in order to increase the resistance to steam flow, the cover further includes: a baffle 50. The baffle 50 is disposed on the housing 10 and is located in the air flow section 301 connected to the steam inlet 101. The baffle 50 is opposite to the steam inlet 101, that is, the steam entering the air flow section 301 from the steam inlet 101 will impact the baffle 50, and the baffle 50 blocks the steam, thereby increasing the resistance to steam flow and reducing the steam flow speed, and can extend the time of steam in the air flow section 301, so that the steam can have sufficient time to condense in the air flow section 301, so that part of the steam condenses into water droplets, reducing the amount of steam discharged, and at the same time, it can allow another part of the steam to have sufficient time to cool down in the air flow section 301, and can reduce the temperature of the other part of the steam, thereby reducing the amount of steam ejected from the exhaust hole 102 and reducing the steam temperature, effectively eliminating the safety hazard of steam scalding people and improving the user experience.

[0082] In some embodiments, the baffle 50 can divert and guide the steam entering the air flow section 301 so that the steam can enter the next air flow section 301 .

[0083] Combination Figure 2 and Figure 3 In some embodiments, in order to increase the resistance to steam flow, the airflow section 301 has a steam outlet end, and the baffle 50 is located between the steam inlet hole 101 and the steam outlet end, that is, the baffle 50 is located on the exhaust path, and the steam entering the airflow section 301 from the steam inlet hole 101 will first impact the baffle 50, and then enter the adjacent airflow section 301 from the steam outlet end of the airflow section 301, so that the baffle 50 can block the steam, increase the resistance to steam flow, reduce the steam flow speed, and extend the time of steam in the airflow section 301, so that the steam can have sufficient time to condense in the airflow section 301, so that part of the steam condenses into water droplets, reducing the amount of steam discharged. At the same time, another part of the steam can have sufficient time to cool down in the airflow section 301, and the temperature of the other part of the steam can be reduced, thereby reducing the amount of steam sprayed from the exhaust hole 102 and reducing the steam temperature, effectively eliminating the safety hazard of steam scalding people and improving the user experience.

[0084] Combination Figure 1 , Figure 2 and Figure 3In some embodiments, in order to allow steam to enter the next airflow channel through the airflow channel connected to the steam inlet 101, the length of the baffle 50 is smaller than the width of the airflow section 301, that is, there is a gap between the baffle 50 and the casing 20 so that steam can flow in the airflow channel.

[0085] Combination Figure 2 and Figure 3 In some embodiments, in order to allow the steam to pass through the baffle 50 smoothly, the cross-sectional shape of the baffle 50 is arc-shaped. The arc is used for transition, which can smoothly guide the steam and reduce the impact force of the steam hitting the baffle 50. This ensures the stability of the installation of the baffle 50, improves the service life of the baffle 50, and at the same time, reduces noise and improves the user experience.

[0086] Combination Figure 2 and Figure 3 In some embodiments, in order to further allow the steam to pass through the baffle 50 smoothly, the recessed direction of the baffle 50 is opposite to the exhaust direction, which can smoothly guide the steam and further reduce the impact force of the steam hitting the baffle 50, thereby ensuring the stability of the installation of the baffle 50 and improving the service life of the baffle 50. At the same time, it can further reduce noise and improve the user experience.

[0087] Combination Figure 4 In some embodiments, in order to increase the resistance to steam flow, the same air flow section 301 has a steam inlet end and a steam outlet end, and there is a height difference between the steam inlet end and the steam outlet end. The air flow section 301 is tilted between the steam inlet end and the steam outlet end. Through the staggered arrangement, the resistance to steam flow is increased, the steam flow speed is reduced, and the time the steam stays in the air flow channel 30 can be extended, so that the steam can have sufficient time to condense in the air flow channel 30, so that part of the steam condenses into water droplets, reducing the amount of steam discharged. At the same time, another part of the steam can have sufficient time to cool down in the air flow channel 30, and the temperature of the other part of the steam can be reduced, thereby reducing the amount of steam ejected from the exhaust hole 102 and reducing the steam temperature, effectively eliminating the safety hazard of steam scalding people and improving the user experience.

[0088] Combination Figure 1 , Figure 2 and Figure 3 In some embodiments, in order to allow the steam from the steam inlet 101 to enter the airflow section 301, a guide channel 60 connected to the airflow section 301 is provided in the shell 10, and the steam inlet 101 is located in the guide channel 60. The steam discharged from the steam inlet 101 is guided into the airflow section 301 through the guide channel 60 to ensure that the steam from the steam inlet 101 can enter the airflow section 301, thereby avoiding leakage of steam from the steam inlet 101.

[0089] In some embodiments, in order to form the guide channel 60, the cover body further includes: a guide member 70. The guide member 70 is arranged to surround the guide channel 60 and is connected to the two innermost enclosures 20 to guide the steam discharged from the steam inlet 101 into the air flow section 301, so as to ensure that the steam from the steam inlet 101 can enter the air flow section 301 and avoid the steam leakage from the steam inlet 101.

[0090] Figure 5 for Figure 1 A schematic diagram of the arrangement of the drainage member of the middle cover; Figure 6 for Figure 5 Schematic diagram of the structure of the drainage piece. Figure 5 and Figure 6 In some embodiments, when the cover is turned over, in order to prevent condensed water from flowing out of the steam inlet 101, the cover further includes: a guide member 110 and a counterweight member 102. The guide member 110 is rotatably arranged on the shell 10, and the guide member 110 and the airflow channel 30 are respectively located on two opposite sides of the shell 10. The guide member 110 has a guide channel 1101 and an airflow inlet 1102 connected to the guide channel 1101, and the guide channel 1101 is connected to the steam inlet 101. The counterweight member 120 is arranged at one end of the guide member 110. Among them, the airflow inlet 1102 is located at the end of the guide member 110 away from the counterweight member 120.

[0091] In some embodiments, when the cover needs to be opened on the electrical device, or the electrical device falls over, under the action of gravity, the counterweight 102 drives the guide member 110 to rotate on the housing 10, so that the counterweight 102 is located at the bottom in the vertical direction, and the airflow inlet 1102 is located at the top in the vertical direction. The condensed water in the airflow channel 30 will not flow out through the airflow inlet 1102, thereby avoiding scalding accidents and improving the user experience. When the electrical device is in normal use, steam can enter the guide channel 1101 through the airflow inlet 1102, and then enter the airflow channel 30 through the steam inlet 101, so that the steam condenses in the airflow channel 30.

[0094] In some embodiments, the electrical device may be an electric kettle. The housing 10 may be mounted on the lower cover 80 of the electric kettle to support the housing 10. When the electric kettle is heating water, the steam generated during the heating process may enter the airflow section 301 through the steam inlet 101, and the flow path of the steam may be increased through the exhaust channel, so that the exhaust path may be extended, and the steam may be fully condensed in the airflow section 301, so that part of the steam condenses into water droplets, reducing the amount of steam discharged, and at the same time, the temperature of another part of the steam may be reduced, thereby reducing the amount of steam ejected from the exhaust hole 102 and reducing the steam temperature, effectively eliminating the safety hazard of steam scalding people, and improving the user experience. The enclosure is mounted on the upper cover 100, and there is a gap between it and the bottom of the housing 10, so that the condensed water in the airflow section 301 with the bottom height gradually decreasing can flow into the steam inlet 101 through the gap.
