Description

Technical Field

[0001] The present application relates to the technical field of thermos flasks, and particularly to a thermos flask lid with a push-to-discharge function. Background Art

[0002] A thermos flask is a common water container in daily life, with a heat preservation function, mainly used to keep boiled water warm. It usually consists of a thermos flask body and a thermos flask lid. The thermos flask lid generally includes a top lid, an inner lid, and a push-type water discharge valve. The lid body is provided with a water discharge cavity. The water discharge valve includes a pressing plate and a valve piece. The valve piece can move relative to the lid body under the pressing of the pressing plate to open or close the water discharge cavity. When the valve piece opens the water discharge cavity, the water discharge cavity connects the inner cavity of the thermos flask body and the spout, enabling the thermos flask to discharge water outwards. When the valve piece closes the water discharge cavity, the inner cavity of the thermos flask body and the spout are no longer connected, and the thermos flask cannot discharge water outwards. The inner cavity of the thermos flask body is sealed, which helps to keep warm. The thermos flask lid has many parts, and it is easy to hide dirt and grime inside. If the daily cleaning is not in place, a large number of bacteria are likely to breed, which can easily affect human health. Therefore, it is necessary to regularly disassemble the various parts of the thermos flask lid for thorough cleaning to improve the cleanliness and reduce the growth of bacteria.

[0003] However, the various parts of the thermos flask lid are firmly assembled and not easily disassembled. Especially for the pressing plate, the existing pressing plates are usually installed on the lid body in a non-detachable manner. The most common solution is that one end of the pressing plate is provided with a cylindrical rotating shaft, and the lid body is provided with a rotating hole adapted to the rotating shaft. The rotating shaft is rotatably assembled in the rotating hole. These solutions require cleaning in a state where the lid body and the pressing plate are connected, resulting in inconvenient cleaning and incomplete cleaning. If the rotating shaft is forcibly pulled out, it is easy to damage the pressing plate and the lid body, affecting normal use. Summary of the Utility Model

[0004] The present application provides a thermos flask lid with a push-to-discharge function to improve or solve to a certain extent the technical problem that the pressing plate of the existing thermos flask lid is not easily disassembled and assembled, resulting in difficult cleaning and incomplete cleaning.

[0005] The technical solution adopted in the present application is as follows:

[0006] A heat-preserving kettle lid with a pressing water outlet function, comprising a top lid and an inner lid detachably connected together. The inner lid is provided with a water outlet valve and a pressing plate for driving the water outlet valve to move to control the water outlet of the heat-preserving kettle. The pressing plate is provided with a rotating part, and the inner lid is provided with a limiting part. The pressing plate is detachably and rotatably mounted on the inner lid through the cooperation of the rotating part and the limiting part. Wherein, the pressing plate has a first position where the rotating part can be disengaged from the limiting part and a second position where the rotating part is restricted in the limiting part. The pressing plate can be rotated around the position connected to the limiting part to switch the pressing plate from the second position to the first position. When the top lid is connected to the inner lid, the top lid restricts the pressing plate from switching from the second position to the first position by abutting against the pressing plate.

[0007] The heat-preserving kettle lid with a pressing water outlet function in this application also has the following additional technical features:

[0008] The rotating part includes a rotating shaft, and the limiting part includes a rotating hole with an opening. The pressing plate is rotatably mounted on the inner lid through the cooperation of the rotating shaft and the rotating hole. When the pressing plate is in the second position, the wall of the opening abuts against the rotating shaft to restrict the rotating shaft from disengaging from the rotating hole. When the pressing plate is in the first position, the shape of the rotating shaft is adapted to the shape of the opening and can pass through the opening to disengage from the rotating hole.

[0009] The cross-section of the rotating shaft has a straight surface and an arc surface connected end to end. A guiding plane extending towards the opening is provided in the rotating hole. When the pressing plate is in the second position, the rotating shaft abuts against the wall of the opening with the arc surface to be blocked in the rotating hole by the opening. When the pressing plate is in the first position, the straight surface avoids the wall of the opening so that the rotating shaft can disengage from the rotating hole along the guiding plane.

[0010] Under the restriction of the top lid and the inner lid, the pressing plate has an upper limit position and a lower limit position within the rotation range. The upper limit position is between the first position and the lower limit position. Wherein, the pressing plate rotates an α angle from the lower limit position to the upper limit position, 15° ≤ α ≤ 30°; and / or, the pressing plate rotates a β angle from the lower limit position to the first position, 45° ≤ β ≤ 90°.

[0011] The rotating part includes a hook part arranged at one end of the pressing plate, the limiting part includes a hanging hole and a hanging shaft located above the hanging hole, the hook part passes through the hanging hole and is hooked and limited by the hanging shaft, and the hanging shaft is used as a rotating fulcrum for rotation; when the pressing plate is located at the second position, the hanging shaft can prevent the hook part from detaching from the hanging hole; when the pressing plate is located at the first position, the posture of the hook part adapts to the hanging hole and can detach from the hanging hole.

[0012] The hook portion has a hanging surface hooked with the hanging shaft, the hanging shaft has a limiting surface corresponding to the hanging surface, and the hanging surface is inclined at an angle γ relative to the limiting surface, wherein γ>0.5°.

[0013] Along the direction in which the hook portion enters the hanging hole, the hanging hole is constructed as a tapered structure with a gradually reduced cross-sectional area.

[0014] A guide portion is provided on the side of the pressure plate facing the water outlet valve. When the pressure plate flips and drives the water outlet valve to move, the water outlet valve slides along the guide portion. The water outlet valve is provided with a spherical surface that abuts against the guide portion, and the guide portion is concave to limit the spherical surface.

[0015] A groove recessed toward the guide portion is provided on a side of the pressure plate away from the water outlet valve.

[0016] The top cover and the inner cover form an accessory installation cavity, the top cover is provided with a through hole, the rotating part is arranged at one end of the pressure plate and cooperates with the limiting part in the accessory installation cavity, and the other end of the pressure plate extends from the through hole to the outside of the thermos pot lid and is provided with a thumb pressing area formed by a depression.

[0017] Due to the adoption of the above technical solution, the technical effects achieved by this application are:

[0018] 1. The heat-preserving kettle lid with pressing water outlet provided by the present application has a pressing plate rotatably and detachably mounted on the inner lid through the cooperation of a rotating part and a limiting part. The pressing plate has a first position where the rotating part can be disengaged from the limiting part, and except for the first position, the rotating part cannot be disengaged from the limiting part. When the top lid is connected to the inner lid, the top lid restricts the pressing plate from switching to the first position by abutting against the pressing plate. Therefore, when the top lid and the inner lid are properly fitted, the rotation range of the pressing plate is restricted, especially preventing the pressing plate from rotating to the first position. At this time, the pressing plate can rotate back and forth within the range defined by the top lid and the inner lid to drive the water outlet valve to move or reset. Therefore, in the normal use state of the heat-preserving kettle lid, under the restricting action of the top lid, the pressing plate will not rotate to the first position by itself and accidentally disengage the rotating part from the limiting part, ensuring that the pressing plate is stably and reliably in the normal use state. When the pressing plate needs to be disassembled, only need to separate the top lid and the inner lid, and then operate the pressing plate to rotate to the first position. At this time, the rotating part is no longer restricted by the top lid and the limiting part, and the rotating part can be easily disengaged from the limiting part to separate the pressing plate from the inner lid, making the disassembly process of the pressing plate worry-free and labor-saving, and also helping to prevent the rotating part and the limiting part from being broken or damaged.

[0019] 2. As a preferred mode of the present application, the pressing plate is rotatably mounted on the inner lid through the cooperation of a rotating shaft and a rotating hole, with a simple structure and convenient cooperation. When the pressing plate is not rotated to the first position, the rotating shaft is limited within the rotating hole and cannot escape. When the pressing plate is rotated to the first position without being restricted by the top lid, the opening of the rotating hole no longer restricts the rotating shaft. The shape of the rotating shaft is adapted to the shape of the opening of the rotating hole, so that the rotating shaft can easily disengage from the opening of the rotating shaft, with convenient and fast operation. And through this adaptability, it is not easy to cause damage to the rotating shaft and the rotating hole during the process of the rotating shaft disengaging from the rotating hole.

[0020] 3. As a preferred mode of the present application, the pressing plate has an upper limit position and a lower limit position within the rotation range under the restriction of the top lid and the inner lid. The pressing plate rotates by an angle α from the lower limit position to the upper limit position, where 15° ≤ α ≤ 30°. The lower limit position and the upper limit position can be respectively defined as two positions where the pressing plate drives the water outlet valve to control the water outlet and stop the water outlet of the heat-preserving kettle. Therefore, by making 15° ≤ α ≤ 30°, it ensures that the pressing plate has a suitable downward pressing stroke to fully open the water outlet valve, guarantee the water outlet flow of the heat-preserving kettle, so as to avoid poor pouring due to too small a stroke and bad user experience due to too large a stroke. In addition, the pressing plate rotates by an angle β from the lower limit position to the first position, where 45° ≤ β ≤ 90°. This ensures that the pressing plate has a suitable upward lifting disassembly stroke, so as to avoid the situation that the required flipping angle for disassembly is too small and does not conform to the habit of ordinary people when lifting an object at one time, resulting in inconvenient operation. At the same time, it also avoids damage to the rotating part and the limiting part caused by the operator easily flipping the pressing plate too much upward due to too small a required flipping angle for disassembly.

[0021] 4. As a preferred embodiment of the present application, the pressing plate is provided with a guiding portion. When the pressing plate flips to drive the water outlet valve to move, the water outlet valve slides along the guiding portion. The water outlet valve is provided with a spherical surface that abuts against the guiding portion, and the guiding portion is concave to limit the spherical surface. Therefore, during the process of the pressing plate flipping and the water outlet valve sliding along the guiding portion, the guiding portion can not only guide the water outlet valve but also play a limiting role, enabling the water outlet valve to move according to a preset stroke, ensuring that the water outlet valve stably and reliably controls the water outlet and cut-off of the thermos flask.

[0022] 5. As a preferred embodiment of the present application, the top cover and the inner cover enclose a fitting installation cavity. The rotating portion is arranged at one end of the pressing plate and cooperates with the limiting portion in the fitting installation cavity. The other end of the pressing plate extends out of the thermos flask cover through the through hole provided in the top cover to serve as the force application position for the user to press, which is convenient for operation. Moreover, the end of the pressing plate extending out of the thermos flask cover is provided with a thumb pressing area formed by a depression, effectively enhancing the force application experience when the user presses the pressing plate with the thumb.

[0049] In order to more clearly illustrate the overall concept of this application, the following will be described in detail by way of examples in conjunction with the drawings of the specification.

[0050] In the following description, many specific details are set forth in order to fully understand this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited by the specific embodiments disclosed below.

[0051] In addition, in the description of this application, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "lateral", "longitudinal", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing this application 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 of this application.

[0052] In this application, unless otherwise clearly defined and limited, the terms "installed", "connected", "connected to", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection, or a communication connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0053] In this application, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of this application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0054] In an embodiment of the present application, a heat-preserving kettle lid with a pressing water outlet is provided. For the convenience of description and understanding, the following content provided by the present application is all elaborated on the basis of the illustrated product structure. Of course, those skilled in the art can understand that the above structure is only a specific example and illustrative description, and cannot constitute a specific limitation on the technical solution provided by the present application.

[0055] Referring to Figures 1 to 18 As shown, a heat-preserving kettle lid with a pressing water outlet provided by the present application includes a top lid 1 and an inner lid 2 detachably connected together. The inner lid 2 is provided with a water outlet valve 3 and a pressing plate 4 for driving the water outlet valve 3 to move to control the water outlet of the heat-preserving kettle. The pressing plate 4 is provided with a rotating part, and the inner lid 2 is provided with a limiting part. The pressing plate 4 is detachably and rotatably installed on the inner lid 2 through the cooperation of the rotating part and the limiting part. Among them, the pressing plate 4 has a first position where the rotating part can be disengaged from the limiting part and a second position where the rotating part is restricted by the limiting part. The pressing plate 4 can rotate around the position connected to the limiting part to switch the pressing plate 4 from the second position to the first position. When the top lid 1 is connected to the inner lid 2, the top lid 1 restricts the pressing plate 4 from switching from the second position to the first position by abutting against the pressing plate 4. At this time, the rotating part will not disengage from the limiting part, and the two are stably assembled, so that the pressing plate 4 can stably rotate around the position connected to the limiting part.

[0056] As Figure 1As shown, an embodiment in which the heat preservation kettle lid is installed on the heat preservation kettle body 6 is schematically illustrated in the present application. Specifically, in the state where the heat preservation kettle lid is integrally assembled, the water outlet valve 3 can be driven to move to a position where the heat preservation kettle can discharge water by controlling the pressing plate 4 to turn downward, and the water outlet valve 3 can be reset to a position where the water discharge of the heat preservation kettle is stopped by controlling the pressing plate 4 to turn upward, which is convenient for operation. The pressing plate 4 is detachably rotatably installed on the inner lid 2 through the cooperation of the rotating part and the limiting part. The pressing plate 4 has a first position where the rotating part can be separated from the limiting part. When the top lid 1 is connected to the inner lid 2, the top lid 1 restricts the pressing plate 4 from switching to the first position by abutting against the pressing plate 4. Therefore, when the top lid 1 and the inner lid 2 are properly matched, the top lid 1 restricts the rotation range of the pressing plate 4, especially preventing the pressing plate 4 from rotating to the first position. At this time, the pressing plate 4 can rotate back and forth within the range defined by the top lid 1 and the inner lid 2 to drive the water outlet valve 3 to move or reset. Therefore, in the normal use state of the heat preservation kettle lid, under the limiting action of the top lid 1, the pressing plate 4 will not rotate to the first position by itself and accidentally separate the rotating part from the limiting part, ensuring that the pressing plate 4 is stably and reliably in the normal use state. When it is necessary to disassemble the pressing plate 4, only need to separate the top lid 1 and the inner lid 2, and then operate the pressing plate 4 to rotate to the first position. At this time, the rotating part is no longer restricted by the top lid 1 and the limiting part, and the rotating part can be easily separated from the limiting part to separate the pressing plate 4 from the inner lid 2, making the disassembly process of the pressing plate 4 worry-free and labor-saving, and also helping to prevent the rotating part and the limiting part from being broken or damaged.

[0057] It should be noted that the present application does not limit the structure of the rotating part provided for the pressing plate 4, the structure of the limiting part corresponding to the rotating part, and the cooperation mode between the rotating part and the limiting part. Any one of the following embodiments can be selected:

[0058] Embodiment 1: As Figures 4 to 10As shown, the rotating part includes a rotating shaft 41, and the limiting part includes a rotating hole 21 with an opening. The pressing plate 4 is rotatably installed on the inner cover 2 through the cooperation of the rotating shaft 41 and the rotating hole 21. When the pressing plate 4 is in the second position, the wall of the opening abuts against the rotating shaft 41 to prevent the rotating shaft 41 from disengaging from the rotating hole 21. When the pressing plate 4 is in the first position, the shape of the rotating shaft 41 matches the shape of the opening, enabling it to pass through the opening and disengage from the rotating hole 21. The pressing plate 4 is rotatably installed on the inner cover 2 through the cooperation of the rotating shaft 41 and the rotating hole 21, with a simple structure and convenient cooperation. The rotation of the rotating shaft 41 in the rotating hole 21 is also relatively smooth and fluent. When the pressing plate 4 is restricted by the top cover 1 and cannot rotate to the first position, the rotating shaft 41 is confined within the rotating hole 21. At this time, the shape of the rotating shaft 41 does not match the shape of the opening of the rotating hole 21, preventing the rotating shaft 41 from disengaging from the rotating hole 21. When the pressing plate 4 rotates to the first position without being restricted by the top cover 1, the opening of the rotating hole 21 no longer restricts the rotating shaft 41. The shape of the rotating shaft 41 matches the shape of the opening of the rotating hole 21, allowing the rotating shaft 41 to easily disengage from the opening of the rotating shaft 41. The operation is convenient and fast, and through this adaptability, damage to the rotating shaft 41 and the rotating hole 21 is not easily caused during the process of the rotating shaft 41 disengaging from the rotating hole 21.

[0059] As a preferred embodiment under this implementation manner, as Figure 4 and Figure 8 shown, the cross-section of the rotating shaft 41 has a straight surface 411 and an arc surface 412 connected end to end. A guiding plane 22 extending towards the opening is provided in the rotating hole 21. When the pressing plate 4 is in the second position, the rotating shaft 41 abuts against the wall of the opening with the arc surface 412, being blocked within the rotating hole 21 by the opening. When the pressing plate 4 is in the first position, the straight surface 411 avoids the wall of the opening, enabling the rotating shaft 41 to disengage from the rotating hole 21 along the guiding plane 22. In this embodiment, the cross-section of the rotating shaft 41 has a straight surface 411 and an arc surface 412 connected end to end, making the rotating shaft 41 as a whole in a D-shaped structure. Under the restrictive action of the top cover 1, when the pressing plate 4 is in the second position, the rotating shaft 41 abuts against the wall of the opening with the arc surface 412. Through the smoothness of the arc surface 412, the smoothness during the rotation of the rotating shaft 41 is ensured, with small rotational friction and little noise generated during the rotation. When the pressing plate 4 is in the first position, the straight surface 411 avoids the wall of the opening, enabling the rotating shaft 41 to disengage from the rotating hole 21 along the guiding plane 22 without being interfered by the wall of the opening of the rotating hole 21, making the disassembly process of the rotating shaft 41 easy and labor-saving, and with a small probability of damage.

[0060] As a preferred embodiment of this embodiment, the pressing plate 4 has an upper limit position and a lower limit position within the rotation range under the restriction of the top cover 1 and the inner cover 2, and the upper limit position is located between the first position and the lower limit position. Preferably, the pressing plate 4 rotates from the lower limit position to the upper limit position by an angle α, 15°≤α≤30°, such as Figure 9 As shown, the solid line shows the state of the pressure plate 4 when it is in the upper limit position, and the dotted line shows the state of the pressure plate 4 when it is in the lower limit position. The pressure plate 4 rotates upward from the lower limit position by an angle α to the upper limit position. The lower limit position and the upper limit position can be respectively defined as the two positions where the pressure plate 4 drives the water outlet valve 3 to control the water outlet of the thermos pot and stops the water outlet. Therefore, by making 15°≤α≤30°, it is ensured that the pressure plate 4 has a downward stroke of a suitable angle to fully open the water outlet valve 3 and ensure the water outlet flow of the thermos pot, so as to avoid the thermos pot being poured poorly due to a too small stroke and the user experience being poor due to a too large stroke. Preferably, the pressure plate 4 rotates from the lower limit position by an angle β to the first position, 45°≤β≤90°, such as Figure 10 As shown, the solid line shows the state of the pressing plate 4 when it is in the upper limit position, and the dotted line shows the state of the pressing plate 4 when it is in the first position. The pressing plate 4 rotates upward from the lower limit position to the first position at an angle of β. By making 45°≤β≤90°, it is ensured that the pressing plate 4 has an upward disassembly stroke of a suitable angle to prevent the turning angle required for disassembly from being too small and inconsistent with the habit of ordinary people when lifting items at one time, resulting in inconvenience in operation. At the same time, it also avoids the operator's excessive turning of the pressing plate 4 upwards due to the small turning angle required for disassembly, thereby causing damage to the rotating part and the limiting part.

[0061] Implementation method 2: Figures 11 to 18 As shown, the rotating part includes a hook part 42 arranged at one end of the pressing plate 4, and the limiting part includes a hanging hole 23 and a hanging shaft 24 located above the hanging hole 23. The hook part 42 passes through the hanging hole 23 and is hooked and limited by the hanging shaft 24, and the hanging shaft 24 is used as a rotating fulcrum for rotation; when the pressing plate 4 is located at the second position, the hanging shaft 24 can prevent the hook part 42 from escaping from the hanging hole 23; when the pressing plate 4 is located at the first position, the posture of the hook part 42 adapts to the hanging hole 23 and can be escaping from the hanging hole 23. Specifically, in order to facilitate the disassembly and assembly of the pressing plate 4, as shown in FIG. Figure 12 , Figure 14 and Figure 15 As shown, the vertical dimension L1 of the hook portion 42 can be made larger than the vertical dimension C of the hanging hole 23, and the lateral dimension L2 of the hook portion 42 can be made smaller than C. Figure 18 The dotted line in the figure shows the state of the pressing plate when it is in the first position, so that the pressing plate 4 is Figure 18When in the vertical state shown in the figure, the posture of the hook portion 42 adapts to the hanging hole 23. The hook portion 42 can enter the hanging hole 23 from the outside or escape from the hanging hole 23. At this time, the vertical state is the state when the pressing plate 4 is in the first position. After the hook portion 42 enters the hanging hole 23 and then flips downward, the hook portion 42 and the hanging shaft 24 form a hooked and limited state. The hook portion 42 can rotate with the hanging shaft 24 as the rotation fulcrum. When the top cover 1 and the inner cover 2 are properly matched, the pressing plate 4 is limited within a rotation range and cannot rotate to the first position. Within this rotation range, the hook portion 42 and the hanging shaft 24 are in a limited state, and the hook portion 42 cannot escape from the hanging hole 23; when the top cover 1 is removed from the inner cover 2, the pressing plate 4 can rotate to the first position and can escape from the hanging hole 23.

[0062] As a preferred embodiment under this embodiment, as Figure 12 、 Figure 15 、 Figure 16 and Figure 17 shown, the hook portion 42 has a hanging surface 421 that is hooked and connected to the hanging shaft 24. The hanging shaft 24 has a limiting surface 241 corresponding to the hanging surface 421. The hanging surface 421 is inclined at a γ angle with respect to the limiting surface 241, where γ > 0.5°. Those skilled in the art can understand that by setting the hanging surface 421 to have an inclination with respect to the limiting surface 241, and this inclination is greater than 0.5°, when the pressing plate 4 is installed on the inner cover 2, an effective gap is formed between the hanging surface 421 and the limiting surface 241, ensuring that the tip position of the hanging shaft 24 abuts against the root of the hook portion 42 to form the rotation fulcrum of the pressing plate 4, enabling the pressing plate 4 to perform an effective reciprocating rotation stroke within the range defined by the top cover 1 and the inner cover 2.

[0063] As a preferred embodiment under this embodiment, as Figure 15 shown, along the direction in which the hook portion 42 enters the hanging hole 23, the hanging hole 23 is configured as a tapered structure with a gradually decreasing cross-sectional area. This kind of structure has a guiding function and can guide the hook portion 42 when the hook portion 42 enters the hanging hole 23, preventing the hook portion 42 from getting stuck during the process of entering the hanging hole 23 and facilitating the disassembly and assembly of the hook portion 42.

[0064] As a preferred embodiment of the present application, as Figure 2 、 Figure 5 and Figure 6As shown, the pressure plate 4 is provided with a guide portion 43 on the side facing the water outlet valve 3. When the pressure plate 4 is turned over to drive the water outlet valve 3 to move, the water outlet valve 3 slides along the guide portion 43. The water outlet valve 3 is provided with a spherical surface 31 that abuts against the guide portion 43. The guide portion 43 is concave to limit the spherical surface 31. It can be understood by those skilled in the art that the pressure plate 4 is provided with a guide portion 43. When the pressure plate 4 is turned over to drive the water outlet valve 3 to move, the water outlet valve 3 slides along the guide portion 43. The water outlet valve 3 is provided with a spherical surface 31 that abuts against the guide portion 43. The guide portion 43 is concave to limit the spherical surface 31. Therefore, in the process of the pressure plate 4 turning over to drive the water outlet valve 3 to slide along the guide portion 43, the guide portion 43 can not only guide the water outlet valve 3, but also limit the water outlet valve 3, so that the water outlet valve 3 moves according to the preset stroke, ensuring that the water outlet valve 3 stably and reliably controls the water outlet of the thermos pot and stops the water outlet.

[0065] Furthermore, if Figure 4 and Figure 6 As shown, the side of the pressure plate 4 facing away from the water outlet valve 3 is provided with a groove 44 recessed toward the guide portion 43. The existence of the groove 44 can effectively ensure that when the pressure plate 4 is pressed, the spherical surface 31 of the water outlet valve 3 will not cause the inner concave surface of the guide portion 43 to produce injection deformation, thereby avoiding problems such as abnormal noise when the pressure plate 4 is pressed.
