The bottom of the pitcher body has a bottom channel for water inlet and outlet, with an upper opening and a lower opening. The valve core can move up and down and rotate within the bottom channel. The lower opening is closed by a cover portion, which has a water outlet. The inner wall of the bottom channel has an upper guide surface, and the cover portion has a lower guide surface facing the upper guide surface. The valve core includes a body and a guide portion, which is located within the movable space enclosed by the upper and lower guide surfaces.

Description

Technical Field

[0001] This application relates to the field of water purifier and pure water pitcher technology, specifically to a pure water pitcher. Background Technology

[0002] A countertop water purifier typically includes a pure water pitcher and a base. The pitcher stores purified drinking water, while the base has a water flow channel connecting to the pitcher, handling both filling and discharging water. When the pitcher is placed on the base, the bottom channel of the pitcher connects with the water flow channel of the base; the pitcher can be removed for independent use.

[0003] In existing systems, a top valve core is installed inside the bottom channel of a pure water kettle to control the opening and closing of the bottom channel; a bottom valve core is installed inside the water flow channel of the kettle base to control the opening and closing of the water flow channel. When the pure water kettle is placed on the kettle base, the top and bottom valve cores are subjected to a mutual pushing force. The top valve core moves upward to open the upper opening of the bottom channel, and the bottom valve core moves downward to open the water flow channel of the kettle base. At this time, water can flow in and out of the pure water kettle. When the pure water kettle is removed from the kettle base, the top and bottom valve cores lose their mutual pushing force: the top valve core moves downward to close the upper opening of the bottom channel, and the bottom valve core moves upward to close the water flow channel of the kettle base.

[0004] However, the above solution has some problems during use: when the water bottle is removed from the base, some water remains in the bottom channel. As the bottle is lifted, this water drips from the bottom opening of the channel under gravity, causing dripping. This drips onto the countertop and floor, increasing the cleaning burden on users. Especially in humid environments such as kitchens, the dripping water may cause bacteria to grow on the countertop, affecting the user experience. To solve the dripping problem, some improvements have been made in existing technologies. For example, a one-way valve is added to the bottom channel to try to prevent water backflow. However, the one-way valve is complex to install and can easily cause spatial interference between the upper and lower valve cores, increasing water flow resistance and affecting water inlet and outlet efficiency. Utility Model Content

[0005] The purpose of this application is to solve the above-mentioned technical problems and provide a pure water pitcher that achieves synchronous opening and closing control of the openings at both ends of the bottom channel of the pitcher through the combined action of the valve core moving up and down and rotating in the bottom channel of the pitcher, thereby improving or solving the problem of water dripping when the pure water pitcher is lifted.

[0006] The technical solution adopted in this application is as follows:

[0007] A pure water kettle includes a kettle body and a valve core. The bottom of the kettle body has a bottom channel for water inlet and outlet. The bottom channel has an upper opening and a lower opening. The valve core can move up and down and rotate within the bottom channel. The lower opening is closed by a cover portion, which has a water outlet. The inner wall of the bottom channel has an upper guide surface, and the cover portion has a lower guide surface facing the upper guide surface. The valve core includes a body and a guide portion. The guide portion is located within the movable space enclosed by the upper and lower guide surfaces. When the valve core moves upward under external pushing force, the guide portion rotates upward along the upper guide surface and drives the body to simultaneously open the upper opening and the water outlet, allowing the inside and outside of the kettle to communicate through the bottom channel. When the valve core moves downward to reset, the guide portion rotates downward along the lower guide surface and drives the body to simultaneously close the upper opening and the water outlet.

[0008] In this technical solution, a valve core that can move up and down and rotate is set in the bottom channel of the kettle. By utilizing the upper and lower openings of the bottom channel and the water inlet of the lid, and the interaction between the guide part of the valve core and the upper guide surface of the inner wall of the bottom channel and the lower guide surface of the lid, the valve core can perform a combined action of moving up and down and rotating in the bottom channel, thereby achieving synchronous opening and closing control of the upper and lower openings of the bottom channel. Specifically, when the pure water kettle is placed on the corresponding kettle stand (when there is an external pushing force), the valve core moves upward and rotates, simultaneously opening the upper and lower openings of the kettle bottom channel. This allows the inside and outside of the kettle to connect through the kettle bottom channel to achieve the function of water inlet and outlet. When the pure water kettle is removed from the kettle stand (without external pushing force), the valve core moves upward and rotates back to its original position, simultaneously closing the upper opening and the water outlet of the kettle bottom channel. This prevents water from flowing out of the kettle and traps the residual water in the kettle bottom channel inside, effectively avoiding the problem of residual water in the kettle bottom channel dripping when the pure water kettle is lifted.

[0009] Both the upper guide surface and the lower guide surface are circumferentially extending inclined surfaces and have a highest point and a lowest point, respectively. The slope difference between the highest and lowest points of the upper guide surface guides the guide part to rotate upward, and the slope difference between the highest and lowest points of the lower guide surface guides the guide part to rotate downward.

[0010] In this technical solution, both the upper and lower guide surfaces are inclined guide structures with a slope difference, which automatically converts the vertical movement of the valve core into rotational motion. The slope difference of the upper guide surface drives the valve core to rotate as it moves upward, opening the upper opening and the water inlet. The slope difference of the lower guide surface drives the valve core to rotate as it moves downward, closing the upper opening and the water inlet. This structural design makes the movement of the valve core more precise and orderly. It can stably achieve the corresponding opening and closing actions in different states (moving upward or resetting downward under external pushing force) by relying on the characteristics of the slope, ensuring the reliability of the water inlet and outlet control of the bottom channel of the kettle, and improving the stability of the water flow control achieved by the entire pure water kettle in cooperation with the kettle seat during use.

[0011] The highest point of the upper guide surface is circumferentially misaligned with the highest point of the lower guide surface, and the lowest point of the upper guide surface is circumferentially misaligned with the lowest point of the lower guide surface; the guide part moves down from the highest point of the upper guide surface and falls onto the inclined surface of the lower guide surface, and the guide part moves up from the lowest point of the lower guide surface and falls onto the inclined surface of the upper guide surface.

[0012] In this technical solution, by circumferentially misaligning the highest point of the upper guide surface with the highest point of the lower guide surface, and also circumferentially misaligning their lowest points, the guide part can move between the two guide surfaces along a specific path. This ensures the continuity and directionality of the valve core's rotational movement, allowing the valve core to accurately switch from the open state to the closed state and from the closed state to the open state according to a predetermined trajectory during its up-and-down movement and rotation. This further optimizes the sealing and connection control mechanism of the entire bottom channel, avoiding problems such as poor sealing and jamming caused by unclear movement trajectories.

[0013] At least two of the guide portions are evenly distributed circumferentially on the body. The number of upper guide surfaces corresponds to the number of guide portions and is arranged symmetrically around the center of the circumference. The number of lower guide surfaces corresponds to the number of guide portions and is arranged symmetrically around the center of the circumference. The cooperation of the upper guide surfaces and the lower guide surfaces guides the valve core to rotate in the same direction.

[0014] In this technical solution, at least two guide sections are evenly distributed circumferentially on the valve core, and the number of upper and lower guide surfaces corresponds to the number of guide surfaces and they are arranged symmetrically around the center. This makes the valve core more evenly stressed during rotation, and it can maintain balance and stability in all directions. This ensures that it can rotate accurately and smoothly in the same direction under external pushing force and during the reset process, thereby more reliably realizing the synchronous opening and closing of the upper opening and the water inlet, and improving the durability and working stability of the entire pure water kettle's inlet and outlet control structure.

[0015] The guide portion is configured as a cylindrical protrusion protruding from the body, and the cylindrical protrusion slides along the upper guide surface or the lower guide surface via the outer cylindrical surface.

[0016] In this technical solution, the guide part is set as a cylindrical protrusion protruding from the body. The outer cylindrical surface of the cylindrical protrusion slides along the upper or lower guide surface, which reduces the friction between the guide part and the guide surface, making the rotation of the valve core smoother. This reduces wear of components and movement jamming caused by friction, helps to maintain a good working condition for a long time, and ensures the normal opening and closing function of the bottom channel of the kettle.

[0017] The cover includes a horizontal cover plate, and the water outlet is opened on the horizontal cover plate; an upwardly extending ring rib is provided along the periphery of the horizontal cover plate, the lower guide surface is formed on the ring rib, and the water outlet is located in the area enclosed by the ring rib.

[0018] In this technical solution, the water inlet is located on a horizontal cover plate, which facilitates the sealing effect of the body when closing the water inlet by the plane contact between the body and the horizontal cover plate, reducing the risk of leakage. The ring rib facilitates cooperation with the guide part of the valve core, providing a reasonable and stable structural basis for the lower guide surface to guide the rotation and downward movement of the valve core, ensuring accurate sealing and continuity of work with other components when closing the water inlet.

[0019] The water inlet is provided with at least two and is evenly distributed along the circumference of the horizontal cover plate. The body is provided with a water-blocking part corresponding to the number of water inlets. A water passage is formed between adjacent water-blocking parts to connect the water inlet and the upper opening. When the valve core moves downward to reset, the water-blocking part rotates to the position corresponding to the water inlet and closes it. When the valve core moves upward under external pushing force, the water-blocking part is misaligned with the water inlet so that the water passage connects with the water inlet.

[0020] In this technical solution, by setting multiple water inlets, the flow area of ​​the bottom channel of the kettle can be increased when it is open, thereby improving the efficiency of water inlet and outlet. The connection and blockage of the water channel are controlled by the misalignment and correspondence between the water baffle and the water inlet, which achieves more precise water flow control. During the up and down movement of the valve core, the on / off state of the kettle body can be precisely controlled, further improving the ability of the pure water kettle to control the water inlet and outlet in different usage scenarios (such as when placed on the kettle stand or removed), and optimizing the overall waterproof and water flow functions.

[0021] The upper end of the main body passes through the upper opening and extends into the pot body, and is equipped with a flexible sealing body; when the valve core moves downward to reset, the flexible sealing body covers and seals the upper opening.

[0022] In this technical solution, a flexible sealing body is installed on the upper end of the valve core body. When the valve core moves downward to reset, the flexible sealing body can cover and seal the upper opening. With the good fit and sealing performance of the flexible sealing body, the sealing performance of the upper opening in the closed state is enhanced, effectively preventing water in the kettle from seeping into the bottom channel of the kettle, further solving the dripping problem and improving the leak-proof effect of the pure water kettle when it is not in use.

[0023] An elastic reset element is provided between the valve core and the inner wall of the bottom channel of the kettle, and the elastic reset element is used to drive the valve core to move downward to reset.

[0024] In this technical solution, an elastic reset component is installed between the valve core and the inner wall of the bottom channel of the kettle. The elastic force of the elastic reset component is used to drive the valve core to move downward to reset, ensuring that the valve core can return to the closed position in a timely and reliable manner after losing external pushing force. This enables the entire water inlet and outlet control structure of the pure water kettle to have an automatic reset function, eliminating the need for additional complicated operations and improving the convenience of use and the stability of the function.

[0025] The lid is provided with a guide hole that runs vertically through it, and the body is provided with a force-bearing guide rod. The force-bearing guide rod passes through the guide hole and extends out of the outside of the bottom channel of the pot to form the point of application of external pushing force.

[0026] In this technical solution, the valve core body is equipped with a force-bearing guide rod that extends through the guide hole to the outside of the bottom channel of the kettle, forming the point of application of the external pushing force. This provides a clear point of application and guidance for the external pushing force to act accurately on the valve core, so that when the valve core is subjected to the force from the kettle seat and other external pushing structures, it can move upward accurately in a predetermined direction and then rotate. This ensures the normal start-up and operation of the entire bottom channel connection control mechanism. Attached Figure Description

[0055] In the embodiments of this application, reference is made to Figures 1 to 15 As shown, this application addresses the problem of water dripping from the bottom channel of a traditional water purifier when it is removed. For ease of explanation and understanding, the following descriptions are based on the illustrated product structure. It is understood by those skilled in the art that the above structure is merely a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application. The water purifier of this application can be applied to commonly used water purifiers, dispensers, and other water purification devices, and can also be applied to other suitable equipment when needed.

[0056] like Figure 1 , Figure 2 , Figure 3 and Figure 11 As shown, the pure water kettle includes a kettle body 1 and a valve core 2. The bottom of the kettle body 1 is provided with a kettle bottom channel 11 for water inlet and outlet. The kettle bottom channel 11 has an upper opening 12 and a lower opening 13. The valve core 2 can move up and down and rotate within the kettle bottom channel 11. The lower opening 13 is closed by a cover part 3. The cover part 3 is provided with a water outlet 31. The inner wall of the kettle bottom channel 11 is provided with an upper guide surface 14. The cover part 3 is provided with a lower guide surface 32 facing the upper guide surface 14. The valve core 2 includes a body 21 and a lower guide surface 22. The guide part 22 is located within the movable space enclosed by the upper guide surface 14 and the lower guide surface 32. When the valve core 2 moves upward under external pushing force, the guide part 22 rotates and moves upward along the upper guide surface 14, and drives the body 21 to open the upper opening 12 and the water inlet 31 at the same time, so that the inside and outside of the kettle body 1 are connected through the bottom channel 11. When the valve core 2 moves downward to reset, the guide part 22 rotates and moves downward along the lower guide surface 32, and drives the body 21 to close the upper opening 12 and the water inlet 31 at the same time.

[0057] Figure 4 The diagram shows the valve core 2 moving down to close the upper opening 12 of the kettle bottom channel 11 and the water inlet 31 of the lid 3. In this state, water inside the kettle body 1 cannot enter the kettle bottom channel 11 through the upper opening 12, and water inside the kettle bottom channel 11 cannot leak downwards through the water inlet 31. Figure 3 The diagram shows the valve core 2 moving upwards to open the upper opening 12 of the bottom channel 11 and the water inlet 31 of the lid 3. In this state, the bottom channel 11 connects the inside of the kettle body 1 with the outside.

[0058] In this application, a valve core 2 that can move up and down and rotate is provided in the bottom channel 11 of the kettle. By utilizing the upper opening 12, lower opening 13 and water inlet 31 of the bottom channel 11, and the interaction between the guide part 22 of the valve core 2 and the upper guide surface 14 of the inner wall of the bottom channel 11 and the lower guide surface 32 of the cover part 3, the valve core 2 can perform a combined action of moving up and down and rotating in the bottom channel 11, thereby realizing the synchronous opening and closing control of the upper opening 12 and the lower opening 13 of the bottom channel 11.

[0059] Specifically, with Figure 12 , Figure 14 and Figure 15 Taking the pure water pitcher as an example of its application in a water purifier, the water purifier is equipped with a pitcher base 4 that is adapted to the pure water pitcher. The pitcher base 4 is provided with a water flow channel 41. The water flow channel 41 is provided with a pusher 42 that can move up and down (which can be configured to open and close the water flow channel 41). The pusher 42 can serve as the external pushing force source for the valve core 2 in the bottom channel 11 of the pitcher. When the pure water kettle is placed on the kettle base 4, the lower valve core 2 pushes the valve core 2 upward. During the upward movement of the valve core 2, it is guided by the upper guide surface 14 through the guide part 22 to rotate and simultaneously open the upper opening 12 and the water outlet 31, so that the inside of the kettle body 1 can be connected to the water flow channel 41 through the bottom channel 11 to realize the water inlet and outlet function. When the pure water kettle is removed from the kettle base 4 (without external pushing force acting on the valve core 2), the valve core 2 can return to its original position downward. It is guided by the lower guide surface 32 through the guide part 22 to rotate and simultaneously close the upper opening 12 and the water outlet 31, preventing water from flowing out of the kettle and trapping the water remaining in the bottom channel 11 inside the bottom channel 11, effectively avoiding the problem of residual water dripping when the pure water kettle is lifted.

[0060] This application does not limit the manner in which the upper guide surface 14 and the lower guide surface 32 guide the valve core 2 to rotate. In one specific embodiment, the valve core 2 can be guided to rotate back and forth within a preset angle range. For example, when the valve core 2 moves upward, the upper guide surface 14 guides the valve core 2 to rotate clockwise, and when the valve core 2 moves downward, the lower guide surface 32 guides the valve core 2 to rotate counterclockwise. In a preferred embodiment, the valve core 2 can also be guided to rotate in a single direction at all times.

[0061] As a preferred embodiment of this application, such as Figure 3 and Figure 4 As shown, both the upper guide surface 14 and the lower guide surface 32 are circumferentially extending inclined surfaces and have a highest point and a lowest point, respectively. The slope difference between the highest and lowest points of the upper guide surface 14 guides the guide part 22 to rotate upward, and the slope difference between the highest and lowest points of the lower guide surface 32 guides the guide part 22 to rotate downward. For ease of understanding, as... Figure 5 , Figure 6 and Figure 12As shown, X1 indicates the highest point of the upper guide surface 14, X2 indicates the lowest point of the upper guide surface 14, X3 indicates the highest point of the lower guide surface 32, and X4 indicates the lowest point of the lower guide surface 32. When the valve core 2 is pushed upward by an external force and reaches the highest point of the upper guide surface 14 under the guidance of the upper guide surface 14, it is stopped. At this time, as... Figure 3 , Figure 7 and Figure 8 As shown, valve core 2 reaches its highest possible position; after the external force is removed, valve core 2 moves downward and, guided by the lower guide surface 32, reaches its lowest point on the lower guide surface 32, where it is stopped. At this time, as... Figure 4 and Figure 10 As shown, the valve core 2 reaches its lowest possible position, at which point it completely seals the upper opening 12 of the bottom channel 11 and the water inlet 31 of the cover 3. Therefore, by using inclined guide structures with a slope difference between the upper guide surface 14 and the lower guide surface 32, the vertical movement of the valve core 2 is automatically converted into rotational motion. The slope difference of the upper guide surface 14 drives the valve core 2 to rotate as it moves upward, opening the upper opening 12 and the water inlet 31. The slope difference of the lower guide surface 32 drives the valve core 2 to rotate as it moves downward, closing the upper opening 12 and the water inlet 31. This structural design makes the movement of the valve core 2 more precise and orderly, enabling it to stably perform corresponding opening and closing actions in different states (moving upward or resetting downward under external pushing force) by relying on the characteristics of the inclined surface. This ensures the reliability of the water inlet and outlet control of the bottom channel 11 and improves the stability of the water flow control achieved by the entire pure water kettle in conjunction with the kettle seat 4 during use.

[0062] In a preferred embodiment, the highest point of the upper guide surface 14 is circumferentially misaligned with the highest point of the lower guide surface 32, and the lowest point of the upper guide surface 14 is circumferentially misaligned with the lowest point of the lower guide surface 32; the guide part 22 moves down from the highest point of the upper guide surface 14 and falls onto the inclined surface of the lower guide surface 32, and the guide part 22 moves up from the lowest point of the lower guide surface 32 and falls onto the inclined surface of the upper guide surface 14. Those skilled in the art will understand that, in order to ensure that the guide part 22 can quickly respond to the guiding action and rotate when it just comes into contact with the upper guide surface 14 or the lower guide surface 32, the landing point of the guide part 22 when it just comes into contact with the upper guide surface 14 and the landing point of the guide part 22 when it just comes into contact with the lower guide surface 32 can be optimized. For example, the landing point of the guide part 22 when it just comes into contact with the upper guide surface 14 can be avoided to be at the lowest point of the upper guide surface 14, and the landing point of the guide part 22 when it just comes into contact with the lower guide surface 32 can be avoided to be at the highest point of the lower guide surface 32. This can prevent the guide part 22 from contacting the lowest point of the upper guide surface 14 or the highest point of the lower guide surface 32, which would cause the force to be in the vertical direction and cause the guide part 22 to jam. Therefore, in this embodiment, the highest point of the upper guide surface 14 is circumferentially offset from the highest point of the lower guide surface 32, and the lowest point of the upper guide surface 14 is circumferentially offset from the lowest point of the lower guide surface 32. This ensures that when the valve core 2 is pushed upward by an external force, the guide part 22 moves vertically from the lowest point of the lower guide surface 32 to a position that just contacts the upper guide surface 14, which is located on the inclined surface between the highest and lowest points of the upper guide surface 14. The inclined surface can quickly generate a component force that causes the guide part 22 to rotate. Similarly, when the valve core 2 moves downward, the guide part 22 moves vertically from the highest point of the upper guide surface 14 to a position that just contacts the lower guide surface 32, which is located on the inclined surface between the highest and lowest points of the lower guide surface 32. The inclined surface can quickly generate a component force that causes the guide part 22 to rotate. Therefore, in this technical solution, by circumferentially misaligning the highest point of the upper guide surface 14 with the highest point of the lower guide surface 32, and also circumferentially misaligning their lowest points, the guide part 22 can move between the two guide surfaces along a specific path, ensuring the continuity and directionality of the rotational movement of the valve core 2. This allows the valve core 2 to accurately switch from the open state to the closed state and from the closed state to the open state according to a predetermined trajectory during its up-and-down movement and rotation, further optimizing the sealing and connection control mechanism of the entire bottom channel 11 and avoiding problems such as poor sealing and jamming caused by unclear movement trajectories.

[0063] Furthermore, such as Figure 8 , Figure 10 , Figure 11 and Figure 12As shown, at least two guides 22 are evenly distributed circumferentially on the body 21. The number of upper guide surfaces 14 corresponds to the number of guides 22 and is arranged symmetrically along the circumferential center. The number of lower guide surfaces 32 corresponds to the number of guides 22 and is arranged symmetrically along the circumferential center. The cooperation of the upper guide surfaces 14 and the lower guide surfaces 32 guides the valve core 2 to rotate in the same direction. The figure shows an embodiment in which the valve core 2 is provided with two symmetrically arranged guide parts 22. The inner wall of the bottom channel 11 of the kettle is also provided with two upper guide surfaces 14, and the cover part 3 is also provided with two lower guide surfaces 32. When the valve core 2 moves upward, the guide parts 22 on both sides contact one upper guide surface 14 respectively. When the valve core 2 moves downward, the guide parts 22 on both sides contact one lower guide surface 32 respectively. This makes the force on the valve core 2 more uniform during rotation, and can maintain balance and stability in all directions. This ensures that it can rotate accurately and smoothly in the same direction under the action of external pushing force and during the reset process. In this way, it can more reliably realize the synchronous opening and closing of the upper opening 12 and the water outlet 31, and improve the durability and working stability of the entire pure water kettle water inlet and outlet control structure. The way the upper guide surface 14 and the lower guide surface 32 guide the valve core 2 to rotate in the same direction is determined by the phase match between the upper guide surface 14 and the lower guide surface 32. Based on the circumferentially offset layout of the highest and lowest points formed by the upper guide surface 14 and the lower guide surface 32, the guide part 22 can naturally continue to rotate in the same direction during transition. In addition, the lowest point of the two lower guide surfaces 32 can share the same position, which can form a locking position for the guide part, and the highest point of the two upper guide surfaces 14 can share the same position, which can also form a locking position for the guide part.

[0064] As a preferred embodiment of this application, such as Figure 11 As shown, the guide part 22 is a cylindrical protrusion protruding from the body 21. The cylindrical protrusion slides along the upper guide surface 14 or the lower guide surface 32 through the outer cylindrical surface, which reduces the friction between the guide part 22 and the guide surface, making the rotation of the valve core 2 smoother. This reduces wear of parts and movement jamming caused by friction, helps to maintain a good working condition for a long time, and ensures the normal opening and closing function of the bottom channel 11.

[0065] As a preferred embodiment of this application, such as Figure 10 and Figure 12As shown, the cover portion 3 includes a horizontal cover plate 33, with a water inlet 31 formed on the horizontal cover plate 33. An upwardly extending annular rib 34 is provided along the periphery of the horizontal cover plate 33, and a lower guide surface 32 is formed on the annular rib 34. The water inlet 31 is located within the area enclosed by the annular rib 34. The water inlet 31 is formed on the horizontal cover plate 33 to facilitate the sealing effect of the body 21 when the water inlet 31 is closed, reducing the risk of leakage, by abutting the plane of the body 21 against the horizontal cover plate 33. Specifically, the upper surface of the annular rib 34 can form a lower guide surface 32. The highest point of the lower guide surface 32 is the highest point of the annular rib 34, and the lowest point of the lower guide surface 32 is the lowest point of the annular rib 34, facilitating cooperation with the guide portion 22 of the valve core 2. When the valve core 2 moves downward, the guide portion 22 is supported on the annular rib 34. The ring rib 34 provides a reasonable and stable structural foundation for the rotation and downward movement of the valve core 2, guiding the lower guide surface 32. This ensures accurate sealing and seamless operation with other components during operations such as closing the water inlet 31. In a preferred embodiment, to facilitate the assembly of the valve core 2, the pot body 1 and the lid 3 can be configured as separate structures. The lid 3 is an independent lid relative to the pot body 1, and it can be connected to the pot body 1 by welding or other suitable methods.

[0066] Furthermore, such as Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, at least two water inlets 31 are provided and evenly distributed along the circumference of the horizontal cover plate 33. The body 21 is provided with water-blocking parts 211 corresponding to the number of water inlets 31. A water passage is formed between adjacent water-blocking parts 211 to connect the water inlets 31 and the upper opening 12. When the valve core 2 moves downward to reset, the water-blocking parts 211 rotate to the position corresponding to close the water inlets 31. When the valve core 2 moves upward under external pushing force, the water-blocking parts 211 and the water inlets 31 are misaligned, so that the water passage is connected to the water inlets 31. The figure shows an embodiment in which the horizontal cover plate 33 is provided with two symmetrical water inlets 31. Correspondingly, two symmetrical water-blocking parts 211 are also provided on the body 21. When the guide part 22 is at the lowest point of the lower guide surface 32, the water-blocking part 211 is exactly against the horizontal cover plate 33 and closes the water outlet 31; when the guide part 22 is at the highest point of the upper guide surface 14, the water-blocking part 211 is higher than the water outlet 31 and offset from it, so that the water passage is directly opposite the water outlet 31. By setting multiple water outlets 31, the flow area of ​​the bottom channel 11 in the open state can be increased, improving the efficiency of water inlet and outlet. By controlling the connection and blockage of the water passage through the offset and correspondence between the water-blocking part 211 and the water outlet 31, more precise water flow control is achieved. During the up and down movement of the valve core 2, the on / off state inside and outside the kettle body 1 can be precisely controlled, further improving the pure water kettle's ability to control the water flow in and out in different usage scenarios (such as when placed on the kettle base 4 or removed), and optimizing the overall waterproof and water flow functions.

[0067] As a preferred embodiment of this application, such as Figure 3 , Figure 4 and Figure 9 As shown, the upper end of the main body 21 passes through the upper opening 12 and extends into the pot body 1, where a flexible sealing body 5 is installed; when the valve core 2 moves downward to reset, the flexible sealing body 5 covers and seals the upper opening 12. Figure 4 The image shows the state of the flexible sealing body 5 sealing the upper opening 12, as shown. Figure 3 The diagram shows the flexible sealing body 5 with its upper opening 12 open. The flexible sealing body 5 is preferably made of a flexible silicone structure. With the good fit and sealing performance of the flexible sealing body 5, the sealing performance of the upper opening 12 is enhanced when closed, effectively preventing water from seeping into the bottom channel 11 of the kettle body 1, further solving the dripping problem and improving the leak-proof effect of the pure water kettle when it is not in use.

[0068] As a preferred embodiment of this application, such as Figure 3 and Figure 4 As shown, an elastic reset element is provided between the valve core 2 and the inner wall of the bottom channel 11 of the kettle. The elastic reset element is used to drive the valve core 2 to move downwards to reset. Preferably, the elastic reset element can be a helical spring 6. The helical spring 6 is sleeved on the valve core 2, with its upper and lower ends abutting against the inner wall of the bottom channel 11 and the valve core 2, respectively. The elastic force of the helical spring 6 is used to drive the valve core 2 to move downwards to reset, ensuring that the valve core 2 can return to the closed position in a timely and reliable manner after losing external pushing force. This gives the entire water inlet and outlet control structure of the pure water kettle an automatic reset function, eliminating the need for additional complicated operations, improving the convenience of use and the stability of the function, and has obvious advantages compared to the valve core 2 simply relying on gravity to reset. In alternative embodiments, the elastic reset element can also be other suitable elastic structures in the prior art, such as wave springs, butterfly springs, or even gas springs.

[0069] As a preferred embodiment of this application, such as Figure 9 , Figure 11 and Figure 12As shown, the lid 3 has a guide hole 35 that runs vertically through it, and the body 21 has a force-bearing guide rod 212. The force-bearing guide rod 212 passes through the guide hole 35 and extends out of the outside of the bottom channel 11 of the kettle to form the point of application of external pushing force. In particular, when the pure water kettle is installed on the kettle base 4, the lower end of the force-bearing guide rod 212 serves as the force-bearing part and moves upward under the pushing force applied by the pusher 42 on the kettle base 4. Specifically, taking the aforementioned embodiment with two symmetrically distributed water inlets 31 as an example, it is preferable to set the guide hole 35 between the two water inlets 31, and the two water blocking parts 211 are symmetrical about the force-bearing guide rod 212. The force-bearing guide rod 212 extends through the guide hole 35 to the outside of the bottom channel 11 to form the point of application of the external pushing force, which provides a clear point of application and guidance for the external pushing force to act accurately on the valve core 2. This allows the valve core 2 to move upward accurately in a predetermined direction and then rotate when subjected to the force from the external pushing structure such as the kettle seat 4, ensuring the normal start-up and operation of the entire bottom channel 11 connection control mechanism.
