Description

Technical Field

[0001] This application relates to the field of base structure technology, and in particular to a base structure and a water purifier. Background Technology

[0002] Currently, the base structures available on the market for placing sparkling water bottles and kettles are all separate. For example, the assembly structure for placing sparkling water bottles and kettles on water purifiers is mostly a separate structure for the water purifier and the sparkling water bottle, occupying a lot of space and having low space utilization. This structural layout makes the machine too large and inconvenient for home placement. For example, Chinese patent application CN217090352U discloses a base, a water purifier, and a mold. The base includes: a base body with an outer surface and an inner surface; a connecting structure disposed on the inner surface, the connecting structure having a mounting surface facing away from the inner surface; and connecting ribs disposed between the connecting structure and the inner surface to connect the connecting structure and the inner surface. This base structure can only accommodate a kettle, not a sparkling water bottle. If a sparkling water bottle is to be placed to make sparkling water, a separate base structure is required. Summary of the Invention

[0003] The purpose of this application is to provide a base structure to solve the problem that the same base structure in the prior art cannot meet the compatibility requirements for placing kettles and sparkling water bottles.

[0004] The embodiments of this application adopt the following technical solution: a base structure applied to a water purifier, the water purifier including a water tank, the base structure including:

[0005] The base has a through cavity extending to the top of the base, and the bottom of the base has a water inlet pipe that communicates with the water tank.

[0006] The lower air intake cover is disposed within the base, and the lower air intake cover has an upwardly extending top rod, the top rod having a hollow cavity extending to both ends of the top rod;

[0007] An air intake cover is disposed on the lower air intake cover, and the air intake cover has a first through hole extending to the top of the air intake cover;

[0008] A movable cover is disposed within the first through hole. The movable cover, together with the lower air inlet cover and the upper air inlet cover, forms a water inlet channel, which is connected to the water inlet pipe. When subjected to a downward force applied by a kettle or sparkling water bottle, the movable cover can move downward to connect the water inlet channel with the kettle or the hollow cavity with the sparkling water bottle. After the downward force is released, the movable cover moves upward to reset its original position.

[0009] An air inlet pipe is connected at one end to the hollow cavity and at the other end to a carbon dioxide cylinder, so that when the sparkling water bottle is placed on the base, carbon dioxide from the carbon dioxide cylinder is introduced into the sparkling water bottle.

[0010] By incorporating a water inlet pipe and an air intake structure including a lower air inlet cover, an upper air inlet cover, and an air inlet pipe on the base structure, a kettle and a sparkling water bottle can be placed on the same base structure to provide both purified and sparkling water. This saves space on the base structure of the water purifier, resulting in a smaller overall size and reduced space occupation.

[0011] In some embodiments, the top of the air intake cover is exposed to the base through the through cavity;

[0012] The movable cover has a second through hole extending to the top of the movable cover;

[0013] The push rod passes through the second through hole and the first through hole, so that when the kettle or sparkling water bottle is placed on the base and a downward force is applied to the movable cover through the top of the first through hole, the push rod can open the first stop valve of the kettle, so that the water inlet channel can communicate with the kettle, or the push rod can be inserted into the air inlet of the sparkling water bottle, so that the hollow cavity can communicate with the sparkling water bottle.

[0014] Because the push rod passes through the second through hole and the first through hole, it can exert a downward force on the movable cover when the kettle or sparkling water bottle is placed on the base, thereby enabling the water inlet channel to connect with the kettle, or the hollow cavity to connect with the sparkling water bottle.

[0015] In some embodiments, the base structure further includes:

[0016] A first switch is disposed on the base to detect whether the kettle is placed on the base, and to send a first signal when the kettle is placed on the base, so as to open the one-way valve between the water tank and the water inlet pipe.

[0017] The second switch is disposed on the base and is used to detect whether a sparkling water bottle is placed on the base. When the sparkling water bottle is placed on the base, a second signal is emitted to open the air inlet valve on the carbon dioxide cylinder, thereby allowing carbon dioxide in the carbon dioxide cylinder to enter the sparkling water bottle. When the air inlet valve is open, the one-way valve is closed.

[0018] By setting the first and second switches, the placement of the kettle and the sparkling water bottle can be detected respectively, and then water can be introduced into the kettle or carbon dioxide can be introduced into the sparkling water bottle according to the placement of the kettle and the sparkling water bottle.

[0019] In some embodiments, the first switch is a tactile switch with a beveled surface at its top. When the kettle or the sparkling water bottle is screwed onto the base, the kettle or the sparkling water bottle applies a force to the beveled surface to trigger the tactile switch, so that the tactile switch emits the first signal.

[0020] The second switch is a proximity switch, which is triggered when the sparkling water bottle is placed on the base and screwed into place, so that the proximity switch emits the second signal.

[0021] The first switch uses a tactile switch design for quick detection of the kettle's placement, while the second switch uses a proximity switch design for quick detection of the sparkling water bottle's placement.

[0022] In some embodiments, the bottom of the base also has a water outlet pipe, the water inlet channel includes a first water inlet channel that can communicate with the kettle and a second water inlet channel that can communicate with the water level tank of the water purifier, and the water outlet pipe is connected to the water inlet channel;

[0023] The base structure also includes a second water stop valve, which is movably mounted on the lower air inlet cover. The top of the second water stop valve abuts against the movable cover. When the movable cover moves downwards, the second water stop valve is pushed downwards by the movable cover to open the second water inlet channel, allowing water in the water tank to enter the water level tank through the second water inlet channel and the outlet pipe. When the kettle detaches from the base, the movable cover moves upwards to reset, and the second water stop valve also moves upwards to reset, blocking the second water inlet channel. The second water stop valve on the base structure enables the opening or blocking of the second water inlet channel.

[0024] In some embodiments, the base structure further includes a first reset member and a first sealing ring. One end of the first reset member is disposed on the water outlet pipe, and the other end of the first reset member is disposed on the second stop valve, for providing an upward force to the second stop valve. The first sealing ring is fastened to the outer wall of the second stop valve, for sealing and blocking the second water inlet channel when the second stop valve moves upward and resets. The first reset member provides an upward force to the second stop valve, enabling the second stop valve to reset and cooperate with the first sealing ring to seal and block the second water inlet channel.

[0025] In some embodiments, the base structure further includes a second reset member. A limiting platform is provided on the outer wall of the lower air intake cover. One end of the second reset member is disposed on the limiting platform, and the other end of the second reset member is disposed on the movable cover. The second reset member is used to provide an upward force to the movable cover to reset it. The upward force provided by the second reset member to the movable cover enables the movable cover to reset.

[0026] In some embodiments, the top of the movable cover is provided with a plurality of water passage holes, which communicate with the water inlet channel so that water in the water inlet channel can enter the kettle through the water passage holes. The water inlet channel and the kettle are connected through the water passage holes on the movable cover.

[0027] This application also provides a water purifier, including a kettle and a sparkling water bottle, and a base structure as described in any of the above embodiments. The base structure has a first screw-on structure, which can cooperate with a second screw-on structure of the kettle or a third screw-on structure of the sparkling water bottle to detachably fix the kettle or the sparkling water bottle to the base. Water purifiers using the above base structure can produce purified water and sparkling water as needed with only a single base structure, reducing the space occupied by the water purifier, while maintaining a relatively small structural size.

[0028] In some embodiments, the kettle includes:

[0029] The kettle body has a water inlet hole at the bottom;

[0030] The lower cover is located at the bottom of the kettle body, and the lower cover has a third through hole through the lower cover. The second screw fastener structure is located on the lower cover.

[0031] The first water stop valve is movably disposed at the water inlet hole. When the kettle is placed on the base, the first water stop valve moves upward under the upward force of the top rod of the air inlet cover in the base structure to open the water inlet hole; when the kettle is removed from the base structure, the first water stop valve resets and blocks the water inlet hole.

[0032] The kettle can be screwed into the base structure via a second screw fastener. Additionally, the first stop valve on the kettle can move up and down depending on whether the kettle is placed on the base, thus opening or closing the water inlet and controlling whether water enters the kettle.

[0033] In some embodiments, the sparkling water bottle includes:

[0034] The sparkling water bottle body has an air inlet at its bottom. When the sparkling water bottle is placed on the base, a push rod of the base structure is inserted into the air inlet, allowing the hollow cavity of the push rod to communicate with the sparkling water bottle body. By providing an air inlet at the bottom of the sparkling water bottle body and allowing the push rod to be inserted into the air inlet when the bottle is placed on the base, communication is achieved between the hollow cavity of the push rod and the sparkling water bottle body, thereby enabling the production of sparkling water.

[0035] In some embodiments, the sparkling water bottle further includes a bottom cap and a magnet. The magnet and the third screw-on structure are both disposed on the bottom cap. When the third screw-on structure is screwed into place relative to the base structure, the magnet triggers a second switch on the base structure to open the air inlet valve on the carbon dioxide cylinder, thereby allowing carbon dioxide in the carbon dioxide cylinder to enter the sparkling water bottle.

[0036] By placing a magnet on the bottom cap of the sparkling water bottle and cooperating with a second switch on the base structure, the air inlet valve on the carbon dioxide cylinder is opened, allowing carbon dioxide to enter the sparkling water bottle to produce sparkling water.

[0037] The beneficial effects of the embodiments of this application are as follows:

[0038] By incorporating a water inlet pipe and an air intake structure including a lower air inlet cover, an upper air inlet cover, and an air inlet pipe on the base structure, a kettle and a sparkling water bottle can be placed on the same base structure to provide both purified and sparkling water. This saves space on the base structure of the water purifier, resulting in a smaller overall size and reduced space occupation. Attached Figure Description

[0057] These and other features of this application will become apparent from the following description of preferred forms of embodiments given as non-limiting examples, with reference to the accompanying drawings.

[0058] It should also be understood that although this application has been described with reference to some specific examples, those skilled in the art can certainly implement many other equivalent forms of this application.

[0059] The above and other aspects, features and advantages of this application will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.

[0060] Specific embodiments of this application are described thereafter with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of this application, which can be implemented in various ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that could obscure the application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in a variety of substantially any suitable detailed structures.

[0061] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0062] To address the problems in the prior art, this application provides a base structure for use in a water purifier. The water purifier includes a water tank 51, which is connected to the base structure for supplying water from the tank 51 to the base structure as needed.

[0063] like Figure 1 , Figure 2 and Figure 3 As shown, the base structure includes a base, a lower air intake cover 37, an upper air intake cover 34, a movable cover 35, and an air intake pipe 41.

[0064] The base has a through cavity extending to the top of the base, and a water inlet pipe 421 at the bottom of the base. The water inlet pipe 421 is connected to the through cavity and can also be connected to the water tank 51, so that water in the water tank 51 can enter the through cavity through the water inlet pipe 421.

[0065] For example, the base may include a lower shell 42 and an upper shell 31, with the upper shell 31 detachably disposed on the lower shell 42. The lower shell 42 and the upper shell 31 enclose a through cavity, the top of which can extend to the top of the base, so that the structure inside the base can be exposed, thereby allowing the kettle and sparkling water bottle to contact other structures inside the through cavity.

[0066] The lower air inlet cover 37 is located inside the base. The upper part of the lower air inlet cover 37 has an upwardly extending push rod 371. The push rod 371 has a hollow cavity extending to both ends. That is, the push rod 371 is a tubular structure open at both ends. The push rod 371 is used to cooperate with the first stop valve 25 of the water bottle when a water bottle is placed on the base, to open the first stop valve 25, thereby allowing water from the water tank 51 to enter the water bottle. The push rod 371 is also used to insert into the air inlet 16 of the sparkling water bottle when a sparkling water bottle is placed on the base, thereby allowing carbon dioxide gas used to make sparkling water to enter the sparkling water bottle through the hollow cavity and the air inlet 16.

[0067] An upper air intake cover 34 is mounted on a lower air intake cover 37 and remains stationary relative to the base and the lower air intake cover 37. The upper air intake cover 34 has a first through-hole extending to its top. A movable cover 35, capable of moving up and down, is disposed within the first through-hole. The top of the first through-hole extends through the upper air intake cover 34, allowing a kettle and a sparkling water bottle to contact the movable cover 35 via the through-hole, thereby applying a downward force to the movable cover 35.

[0068] Specifically, the movable cover 35 is disposed within the first through hole, and the movable cover 35, together with the lower air inlet cover 37 and the upper air inlet cover 34, forms a water inlet channel. The water inlet channel is connected to the water inlet pipe 421, allowing water from the water tank 51 to enter the water inlet channel via the water inlet pipe 421, and then enter the kettle through the water inlet channel. When subjected to a downward force applied by the kettle or sparkling water bottle, the movable cover 35 can move downward, connecting the water inlet channel to the kettle or the hollow cavity to the sparkling water bottle. After the downward force is released, the movable cover 35 can move upward to reset, and the reset force can be provided by a reset component, such as a spring 36.

[0069] One end of the air inlet pipe 41 is connected to the hollow cavity, and the other end is connected to the carbon dioxide cylinder 59, so that when a sparkling water bottle is placed on the base, carbon dioxide from the carbon dioxide cylinder 59 can be introduced into the sparkling water bottle. The sparkling water bottle is pre-filled with a certain amount of water, and sparkling water can be made after carbon dioxide is introduced into the sparkling water bottle.

[0070] This embodiment of the application, by setting a water inlet pipe 421 and an air inlet structure including a lower air inlet cover 37, an upper air inlet cover 34, and an air inlet pipe 41 on the base structure, can achieve compatible placement of a kettle and a sparkling water bottle on the same base structure for providing purified water and sparkling water. This saves space on the base structure of the water purifier, making the overall size of the water purifier smaller and reducing its space occupation.

[0071] In some embodiments, combined with Figure 2 The top of the air intake cover 34 is exposed to the base through the through cavity. The movable cover 35 has a second through hole extending to the top of the movable cover 35. The push rod 371 passes through the second through hole and the first through hole sequentially from bottom to top. When the kettle is placed on the base and a downward force is applied to the movable cover 35 through the top of the first through hole, the first stop valve 25 of the kettle can contact the push rod 371, and the push rod 371 can push the first stop valve 25 of the kettle upward to open the first stop valve 25 of the kettle, thereby allowing the water inlet channel in the base structure to communicate with the kettle, and the water in the water inlet channel can enter the kettle (in conjunction with...). Figure 2 and Figure 4 Alternatively, when the sparkling water bottle is placed on the base and a downward force is applied to the movable cover 35 through the top of the first through hole, the push rod 371 can be inserted into the air inlet 16 of the sparkling water bottle, so that the hollow cavity can communicate with the sparkling water bottle, thereby allowing carbon dioxide to enter the sparkling water bottle through the hollow cavity and the air inlet 16 to produce sparkling water (in combination with...). Figure 2 and Figure 7 ).

[0072] Because the top rod 371 passes through the second through hole and the first through hole, it can exert a downward force on the movable cover 35 when the kettle or sparkling water bottle is placed on the base, thereby enabling the water inlet channel to communicate with the kettle, or the hollow cavity to communicate with the sparkling water bottle.

[0073] In some embodiments, combined again Figure 1 The base structure also includes a first switch 33 and a second switch 32. The first switch 33 is disposed on the base and is used to detect whether a kettle is placed on the base. When a kettle is placed on the base, a first signal is emitted to open the one-way valve between the water tank 51 and the water inlet pipe 421, so that the water in the water tank 51 can enter the water inlet pipe 421, and then enter the water inlet channel and the kettle through the water inlet pipe 421.

[0074] The second switch 32 is mounted on the base and is used to detect whether a sparkling water bottle is placed on the base. When a sparkling water bottle is placed on the base, a second signal is sent to open the air inlet valve on the carbon dioxide cylinder 59, allowing carbon dioxide from the carbon dioxide cylinder 59 to enter the sparkling water bottle. When the air inlet valve is open, the one-way valve closes. For example, both the first switch 33 and the second switch 32 are connected to the controller of the water purifier. The controller receives the first signal and the second signal sent by the first switch 33 and the second switch 32. When the controller only receives the first signal, it controls the one-way valve to open; when the controller receives both the first and second signals, it controls the one-way valve to close and the air inlet valve to open.

[0075] By setting the first switch 33 and the second switch 32, the placement of the kettle and the sparkling water bottle can be detected respectively, and then the action of whether to introduce water into the kettle and whether to introduce carbon dioxide into the sparkling water bottle can be controlled according to the placement of the kettle and the sparkling water bottle.

[0076] In some embodiments, the first switch 33 is a tactile switch, combined with Figure 3 The tactile switch has a bevel 331 on its top. When a kettle or sparkling water bottle is screwed onto the base, the kettle or sparkling water bottle applies force to the bevel 331 to trigger the tactile switch, causing it to emit a first signal. It is understood that the first switch 33 can also adopt other switch structures; this is merely an example and does not constitute a limitation on the scope of the claims.

[0077] The second switch 32 is a proximity switch, which is triggered when the sparkling water bottle is placed on the base and screwed into place, causing the proximity switch to emit a second signal. Similarly, it is understood that the second switch 32 may also adopt other switch structures; this is merely an example and does not constitute a limitation on the scope of the claims.

[0078] The first switch 33 adopts a tactile switch design to facilitate quick detection of the placement of the kettle, and the second switch 32 adopts a proximity switch design to facilitate quick detection of the placement of the sparkling water bottle.

[0079] In some embodiments, combined with Figure 2The bottom of the base also has a water outlet pipe 422. The water inlet channel includes a first water inlet channel that can be connected to the kettle and a second water inlet channel that can be connected to the water level tank 52 of the water purifier. The water outlet pipe 422 is connected to the water inlet channel. Water in the water tank 51 can enter the water inlet channel through the water outlet pipe 421. When both the first water inlet channel and the second water inlet channel are open, the water in the water inlet channel is divided into two paths: one path enters the kettle through the first water inlet channel, and the other path enters the water level tank 52 through the second water inlet channel. Specifically, when the kettle is placed on the base, the top rod 371 opens the first stop valve 25, the water level tank 52 is connected to the kettle and maintained at a water level line, and then the kettle is rotated, the kettle triggers the first switch 33, the first switch 33 sends the first signal, when the water purifier controller receives the first signal, the controller sends a control signal to the booster pump 56 set between the water inlet pipe 421 and the water tank 51 to control the booster pump 56 to start, so that the water in the water tank 51 can enter the kettle through the water purification pipe 421.

[0080] The water level tank 52 is equipped with a low-water-level detection float and a high-water-level detection float (or water level float switch), used to detect the low and high water levels in the tank, respectively. The tank also contains a reed switch that works in conjunction with the magnet inside the float. This reed switch is connected to the water purifier's controller to send the water level information from the tank to the controller. When the water level reaches the high level, the high-water-level detection float sends a high-water-level signal to the controller. Upon receiving this signal, the controller stops the booster pump to cease water purification. When the water level drops to the low level, the low-water-level detection float sends a low-water-level signal to the controller. Upon receiving this signal, the controller starts the booster pump to begin water purification. When a kettle is placed on the base and the water purifier's controller receives the low-water-level signal from the tank 52, water purification begins. Figure 10 Raw water is pressurized from water tank 51 by booster pump 56, then passes through filter element 57, three-way solenoid valve 58, and inlet pipe 421 into the inlet channel. It then splits into two paths: one path enters the kettle through first stop valve 25; the other path enters the water level tank 52 through outlet pipe 422, ensuring the water level in tank 52 matches the water level in the kettle. This allows the water level in the kettle to be determined based on the water level in tank 52, facilitating the decision to produce purified water. Figure 2The base structure also includes a second stop valve 38, which is movably mounted on the lower air inlet cover 37. The top of the second stop valve 38 abuts against the movable cover 35. The second stop valve 38 can be pushed downward by the movable cover 35 when the movable cover 35 moves downward, thereby opening the second water inlet channel, allowing water in the water tank 51 to enter the water level tank 52 through the second water inlet channel and the water outlet pipe 422. The second stop valve 38 on the base structure can open or block the second water inlet channel. When the kettle is removed from the base, the movable cover 35 moves upward to reset, and the second stop valve 38 can also move upward to reset, blocking the second water inlet channel. Specifically, when the water purifier kettle needs to be removed, the kettle needs to be rotated first, triggering the first switch 33 and generating a first signal. At this time, the controller of the water purifier receives the first signal. If the water purifier is normally producing purified water, it will stop producing purified water after receiving the first signal. After the kettle is removed from the base, the second stop valve 38 will reset and block the second water inlet channel to prevent water from flowing back into the water level tank 52. At the same time, the first stop valve 25 at the bottom of the kettle will also reset and block the water inlet hole of the kettle to prevent leakage.

[0081] In some embodiments, combined with Figure 2 and Figure 3 The base structure also includes a first reset member 40 and a first sealing ring 39. One end of the first reset member 40 is disposed on the water outlet pipe 422, and the other end is disposed on the second stop valve 38, providing an upward force to the second stop valve 38 so that the second stop valve 38 can be reset. The first sealing ring 39 is fastened to the outer wall of the second stop valve 38, and an annular mounting groove can be provided on the outer wall of the second stop valve 38 to install the first sealing ring 39 into the mounting groove. The first sealing ring 39 is used to seal and block the second water inlet channel when the second stop valve 38 moves upward and resets, preventing water in the first water inlet channel from re-entering the water level tank 52 through the second water inlet channel. The first reset member 40 provides an upward force to the second stop valve 38, enabling the second stop valve 38 to reset and cooperate with the first sealing ring 39 to seal and block the second water inlet channel.

[0082] In some embodiments, combined with Figure 2 and Figure 3The base structure also includes a second reset member 36. A limiting platform is provided on the outer wall of the lower air intake cover 37. The limiting platform can be composed of the top surface of the reinforcing ribs provided on the outer wall of the lower air intake cover 37. Of course, other structural methods can also be used. This is only used as an example and does not constitute a limitation on the scope of protection of the claims. One end of the second reset member 36 is provided on the limiting platform, and the other end of the second reset member 36 is provided on the movable cover, specifically on the top wall of the second through hole. When the movable cover 35 is moved downward by the downward force of the kettle or sparkling water bottle, the movable cover 35 compresses the second reset member 36; and when the kettle or sparkling water bottle releases the downward force on the movable cover 35, the second reset member 36 extends and retracts to reset, and provides an upward force to the movable cover 35 to reset it. The second reset member 36 provides an upward force to the movable cover 35 so that the movable cover 35 can be reset.

[0083] In some embodiments, combined with Figure 3 The top of the movable cover 35 is provided with several water passage holes, which communicate with the water inlet channel to allow water in the water inlet channel to enter the kettle through the water passage holes. The water passage holes can be evenly distributed on the top of the movable cover 35 to ensure that water in the water inlet channel enters the kettle evenly and smoothly. For example, the water passage holes can be evenly distributed around the second through hole. The water inlet channel and the kettle are connected through the water passage holes on the movable cover 35.

[0084] Based on the same inventive concept, this application also provides a water purifier, which includes a kettle and a sparkling water bottle, and further includes a base structure as described in any of the above embodiments. Figure 1 , Figure 6 and Figure 9 The base structure has a first screw fastener 311, which can engage with a second screw fastener 261 of the kettle or a third screw fastener 191 of the sparkling water bottle, allowing the kettle or sparkling water bottle to be detachably fixed to the base. With this base structure, the water purifier can produce purified water and sparkling water as needed within a smaller structural size, reducing the space occupied by the water purifier.

[0085] In some embodiments, combined with Figure 4 , Figure 5 and Figure 6 The kettle includes a kettle body 22, a lower lid 26, and a first stop valve 25.

[0086] The kettle body 22 has an open top, where a lid 21 can be installed. The lid 21 is closable and can be opened and closed. The bottom of the kettle body 22 has a water inlet. A lower cover 26 is located at the bottom of the kettle body 22 and has a third through hole. When the kettle is placed on the base, the push rod 371 can pass through the third through hole to contact and open the first stop valve 25. A second screw-on structure 261 can be provided on the lower cover 26.

[0087] The first stop valve 25 is movably located at the water inlet. When the kettle is placed on the base, the first stop valve 25 moves upward under the upward force of the push rod 371 of the air inlet cover 37 in the base structure, releasing the blockage of the water inlet and opening it. In its natural state, the first stop valve 25 is blocked at the water inlet. Only when the kettle is placed on the base structure and the push rod 371 of the base structure lifts the first stop valve 25 can the water inlet be opened, allowing water from the base structure to enter the kettle through the water inlet. When the kettle is removed from the base structure, the first stop valve 25 resets and re-blocks the water inlet to prevent leakage from the bottom of the kettle.

[0088] The kettle can be screwed into the base structure via the second screw fastener 261. In addition, the first stop valve 25 on the kettle can move up and down depending on whether the kettle is placed on the base, so as to open or close the water inlet hole, thereby controlling whether water enters the kettle.

[0089] Specifically, in combination Figure 4 and Figure 5 The kettle may also include a third reset element 24 and a second sealing ring 23.

[0090] The upper part of the first stop valve 25 extends through the water inlet hole into the kettle body 22, and the second sealing ring 23 is fastened to the outer wall of the upper part of the first stop valve 25. One end of the third reset member 24 is disposed on the first stop valve 25, and the other end of the third reset member 24 is disposed on the bottom surface of the kettle body 22. When the kettle is placed on the base structure, the first stop valve 25 moves upward under the upward force of the top rod 371 of the air inlet cover 37 to open the water inlet hole, at which time the third reset member 24 is compressed; when the kettle is removed from the base structure, the third reset member 24 extends and retracts to reset, providing a downward reset force for the first stop valve 25, so that the first stop valve 25 resets and seals the water inlet hole.

[0091] In some embodiments, combined with Figure 7 , Figure 8 and Figure 9The sparkling water bottle includes a bottle body 12. An air inlet 16 is located at the bottom of the bottle body 12. When the sparkling water bottle is placed on a base, a push rod 371 of the base structure is inserted into the air inlet 16, allowing the hollow cavity of the push rod 371 to communicate with the bottle body 12. This allows gas from the carbon dioxide cylinder 59 to enter the air inlet 16 through the hollow cavity of the push rod 371, and then enter the sparkling water bottle. By providing an air inlet 16 at the bottom of the bottle body 12 and ensuring that the push rod 371 can be inserted into the air inlet 16 when the bottle is placed on the base, communication is achieved between the hollow cavity of the push rod 371 and the bottle body 12, thus enabling the production of sparkling water.

[0092] Specifically, the sparkling water bottle also includes a bottom cap 19, an inner cap 13, and a silicone sleeve 15. The bottom cap 19 is detachably mounted on the bottom of the sparkling water bottle body 12. For example, the bottom cap 19 has internal threads, and the bottom of the sparkling water bottle body 12 has external threads; the bottom cap 19 and the sparkling water bottle are detachably connected via these threads. The bottom cap 19 has a fourth through hole, and the bottom cap 19 and the sparkling water bottle body 12 together form an air intake channel. The inner cap 13 is sealed at the open bottom of the sparkling water bottle, and has a vent hole 131 for connecting the sparkling water bottle and the air intake channel.

[0093] The air inlet 16 can be located at the fourth through hole. The air inlet 16 has an air inlet chamber 162, and a small air inlet hole 161 penetrating the side wall of the air inlet 16 is provided. When the sparkling water bottle is placed on the base, the push rod 371 of the base structure is inserted into the air inlet 16 so that the hollow cavity of the push rod 371 can communicate with the air inlet chamber 162. This allows the gas in the carbon dioxide cylinder 59 to enter the sparkling water bottle through the hollow cavity and the air inlet chamber 162, opening the small air inlet hole 161, so that the gas can enter the sparkling water bottle through the air inlet channel and the vent hole 131.

[0094] The silicone sleeve 15 tightly covers the outer wall of the air inlet 16 and is used to seal the air inlet hole 161. When the sparkling water bottle is placed on the base structure, the top rod 371 of the base structure is inserted into the air inlet 16. When the carbon dioxide cylinder 59 delivers carbon dioxide to the air inlet chamber 162 through the hollow cavity of the top rod 371, under the action of gas pressure, the carbon dioxide gas pushes open the silicone sleeve 15 sealing the air inlet hole 161 through the air inlet hole 161, thereby allowing the carbon dioxide gas to enter the air inlet channel, and then enter the sparkling water bottle through the air inlet channel and the vent hole 131.

[0095] The sparkling water bottle also includes a third sealing ring 14 and a fourth sealing ring 17. The third sealing ring 14 is disposed between the outer wall of the inner cap 13 and the inner wall of the opening at the bottom of the sparkling water bottle to achieve a seal between the inner cap 13 and the opening at the bottom of the sparkling water bottle. The fourth sealing ring 17 is disposed between the air inlet 16 and the fourth through hole to achieve a seal of the air intake channel.

[0096] In some embodiments, combined with Figure 9 The sparkling water bottle also includes a bottom cap 19 and a magnet 18. The magnet 18 and a third screw-on structure 191 are both located on the bottom cap 19. When the third screw-on structure 191 is screwed into place relative to the base structure, the magnet 18 triggers a second switch 32 on the base structure. The second switch 32 sends a second signal to the controller. Upon receiving the second signal, the controller issues a control signal to open the inlet valve on the carbon dioxide cylinder 59, allowing carbon dioxide from the cylinder 59 to enter the sparkling water bottle. By providing a magnet 18 on the bottom cap 19 of the sparkling water bottle and cooperating with the second switch 32 on the base structure, the inlet valve on the carbon dioxide cylinder 59 is opened, allowing carbon dioxide to enter the sparkling water bottle to produce sparkling water.

[0097] The sparkling water bottle also includes a cap 11, which is located at the opening on the top of the sparkling water bottle body 12. The cap 11 can be detachably connected to the sparkling water bottle body 12 via threads. A pressure relief valve can be provided inside the cap 11 to release pressure when the pressure inside the sparkling water bottle body 12 is too high. For example, two 6KG pressure relief valves can be provided inside the cap.

[0098] To further explain the working principle of a water purifier, we can combine... Figure 10When the controller receives the second signal, it sends a control signal to the water pump 55 to start the pumping action. The top of the carbon dioxide cylinder 59 is provided with a hydraulic chamber 54, which is connected to the water level tank 52 through a pipe and to the water pump 55 through another pipe. The water pump 55 is connected to the cold water tank 53 so that the water in the cold water tank 53 is pumped into the hydraulic chamber 54 and a thrust is generated on the gas in the carbon dioxide cylinder 59, which pushes the air inlet valve on the carbon dioxide cylinder 59 to open, so that the carbon dioxide in the carbon dioxide cylinder 59 can enter the air inlet pipe 41. During inflation, if the pressure inside the carbon dioxide cylinder 59 is too high, the two 6KG pressure relief valves inside the cap 11 at the top of the sparkling water bottle will release the excess pressure to the outside. If the pressure relief valves cannot release the pressure in time, when the internal pressure of the sparkling water bottle reaches 8KG, the top of the sparkling water bottle will release the pressure violently, and the internal explosion-proof membrane will break open a small hole to the outside. After inflation, the silicone sleeve 15 loses the pressure from the small vent hole and returns to its original shape, wrapping around the air inlet 16 to prevent water and air leakage. When the water purifier is making purified water, when the reed switch in the water level tank 52 detects that the liquid level in the water level tank 52 is low, and at the same time the kettle is placed on the base structure, the controller controls the booster pump 56 to start, so that the water in the water tank 51 is filtered through the filter element 57 to make purified water. The three-way solenoid valve 58 is opened to the bottom water inlet pipe 421 of the base (when the liquid level in the cold water tank 53 is low, water can be added to the cold water tank 53 first by opening the three-way solenoid valve 58, and then purified water is made). Water enters the kettle through the water inlet pipe 421. When the water level tank 52 reaches the high water level, the booster pump 56 stops working.

[0099] The foregoing has described in detail several embodiments of this application, but this application is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications based on the concept of this application, and all such variations and modifications should fall within the scope of protection claimed in this application.
