[0172] Optionally, the main unit includes a base, the first guide structure is disposed on the base, and the second guide structure is disposed on the bottom wall of the detachable kettle.

[0173] The present invention has the following technical effects:

[0174] This invention provides a detachable water bottle. By adding a vent, when the detachable water bottle is installed on the main unit, the vent is in the open state, allowing the bottle cavity to communicate with the atmosphere. This ensures that water can smoothly enter the bottle cavity to a preset high water level (increasing water storage capacity) or be supplied to a preset low water level (facilitating the use of all water). Furthermore, when the detachable water bottle is removed from the main unit, the vent is in the closed state, ensuring that the water is sealed in the bottle cavity. The detachable water bottle can be placed at any angle, for example, horizontally in a refrigerator for chilling before drinking, enriching the functionality of the detachable water bottle. The detachable water bottle offers diverse storage options; in addition to storing purified water, it can also be used to store other liquid foods (such as beverages). Attached Figure Description

[0223] First Implementation Method

[0224] The following is based on Figures 1 to 14 The water purification device according to the first embodiment of the present invention will be described in detail.

[0225] In this embodiment, such as Figures 1 to 5 , Figure 7 , Figure 14 As shown, the water purification device 100 includes a main unit 1 and a detachable kettle 2. The detachable kettle 2 includes a kettle cavity 21, an air vent 221, and a kettle body water inlet 234. The kettle cavity 21 is used to contain water, the air vent 221 is connected to the kettle cavity 21, and the kettle body water inlet 234 is used to connect to the water circuit of the main unit 1 of the water purification device 100.

[0226] like Figures 3 to 5 , Figure 7 As shown, when the detachable kettle 2 is installed on the main unit 1, the kettle body water inlet 234 is connected to the main unit 1 in a water circuit state, the vent 221 is open, and the detachable kettle 2 is in a non-sealed state. When the detachable kettle 2 needs to be refilled, the clean water in the main unit 1 enters the kettle cavity 21 through the kettle body water inlet 234, providing clean water to the detachable kettle 2. Furthermore, during the process of water entering the detachable kettle 2, as the water level rises, the air in the kettle cavity 21 is compressed and discharged through the vent 221, ensuring that the water in the kettle cavity 21 can smoothly reach the preset high water level. Figure 7 and Figure 10 As shown, when the detachable kettle 2 is removed from the main unit 1, the vent 221 switches to the closed state, making the detachable kettle 2 in a sealed state, preventing water in the kettle cavity 21 from leaking out of the vent 221, and ensuring that the water is sealed in the kettle cavity 21. Of course, if the detachable kettle is equipped with an automatic water outlet, water can be taken without removing the detachable kettle 2. Under the power provided by the pump in the main unit 1, the detachable kettle 2 can automatically provide purified water to the user (for example, purified water is provided through the kettle body water outlet 234, that is, the kettle body water outlet 234 can be used for both water intake and water output). During the process of taking water through the water outlet, the vent 221, which is in the open state, can also be used to introduce air into the kettle cavity 21 to ensure that water can be smoothly discharged from the water outlet.

[0227] Through the above technical solution, by adding a vent 221 to the detachable water bottle 2, when the detachable water bottle 2 is installed on the main unit 1, the vent 221 is in the open state, allowing the bottle cavity 21 to remain connected to the atmosphere, thereby ensuring that the bottle cavity 21 can smoothly receive water up to the preset high water level (increasing water storage capacity) or supply water up to the preset low water level (facilitating the use of all water). Furthermore, when the detachable water bottle 2 is detached from the main unit 1, the vent 221 is in the closed state, ensuring that the water is sealed in the bottle cavity 21 or that water does not spill out of the bottle cavity. The detachable water bottle 2 can be placed at any angle, for example, horizontally placed in the refrigerator, and consumed after refrigeration, enriching the functionality of the detachable water bottle 2. The detachable water bottle 2 offers diverse storage options; in addition to storing purified water, it can also be used to store other liquid foods (such as alcoholic beverages).

[0228] In one embodiment, when the detachable kettle 2 switches between an installed state and a detached state, the water purifier 100 switches the vent 221 between an open state and a closed state via a non-manual triggering method. Compared to the solution of manually opening or closing the vent 221, the opening and closing of the vent 221 in this solution does not require manual triggering by the user, making it convenient to use and avoiding problems such as the user forgetting to open or close the vent 221, which could affect the use of the detachable kettle 2 and the water purifier, and cause the user to mistakenly believe that the machine is malfunctioning.

[0229] Furthermore, such as Figures 2 to 4 , Figure 10 As shown, the host 1 is provided with a first trigger structure 111, which is used to trigger the vent 221 to switch between an open state and a closed state.

[0230] Furthermore, such as Figure 2 As shown, the host 1 includes a housing 11, and a first trigger structure 111 is disposed on the housing 11 for easy processing.

[0231] In one implementation, such as Figure 4 and Figure 7 As shown, the vent 221 is located on the top wall of the detachable kettle 2. This allows the preset high water level of the kettle cavity 21 to be positioned as close as possible to the top wall of the detachable kettle 2, making full use of the space in the kettle cavity 21 to hold more water. Of course, the vent 221 can also be located on the circumferential side wall of the detachable kettle 2, as close as possible to the top wall of the detachable kettle 2.

[0232] In one implementation, such as Figure 2 , Figure 3 and Figure 7As shown, the detachable kettle 2 includes a lid assembly 22 and a kettle body 23. The lid assembly 22 and the kettle body 23 together form a kettle cavity 21. A vent 221 is provided on the lid assembly 22. The detachable kettle 2 is configured as a split structure, which reduces the processing difficulty and makes it easier to clean the kettle cavity 21.

[0233] Furthermore, such as Figure 4 and Figure 7 As shown, the kettle lid assembly 22 includes a fixed lid body 222 and a movable lid body 223. The fixed lid body 222 is connected to the kettle body 23 and has a water outlet 2224. The movable lid body 223 is movably connected to the fixed lid body 222. The kettle lid assembly 22 is designed as a split structure for ease of manufacturing. When the movable lid body 223 is in the closed position, it closes the water outlet 2224. Normally, when the user does not need to take water, the movable lid body 223 is in the closed position. This prevents water from leaking from the kettle cavity 21 through the water outlet 2224 and also prevents external dirt from entering the kettle cavity 21 through the water outlet 2224, thus avoiding water contamination. Figure 7 and Figure 11 As shown, when the movable cover 223 moves to the open position, the movable cover 223 opens the water outlet 2224, and the user can tilt the detachable kettle 2 to pour water for drinking through the water outlet 2224.

[0234] Furthermore, such as Figure 4 , Figure 6 and Figure 7 As shown, the fixed lid 222 includes a first lid 2221 and a second lid 2222. The first lid 2221 is used to connect to the kettle body 23, and the second lid 2222 is fixed to the first lid 2221 (e.g., by ultrasonic welding). The two are sealed together by a first sealing element 2223 to ensure airtightness. The first lid 2221, the second lid 2222, and the movable lid 223 are arranged sequentially in a direction away from the kettle cavity 21. In this design, the fixed lid 222 is configured as a split structure to simplify the structure of a single lid, facilitate processing, and reduce the defect rate during processing.

[0235] Furthermore, such as Figure 4 , Figure 6 and Figure 7As shown, the detachable kettle 2 also includes a mounting bracket 24, which is fixed to the kettle body 23 (e.g., by induced welding for sealing). The first lid 2221 is detachably connected to the mounting bracket 24, and the two are sealed by a second seal 25 to ensure a tight seal. When the lid assembly 22 is damaged, it can be removed from the mounting bracket 24 for repair or replacement. Furthermore, the mounting bracket 24 replaces the kettle body 23 to connect with the first lid 2221. This reduces or avoids modifications to the structure of the kettle body 23. Additionally, the mounting bracket 24 is compact and has a lower processing cost than the kettle body 23. Improving the structural strength of the mounting bracket 24 ensures the stability of the lid assembly 22 and also helps control costs.

[0236] Furthermore, such as Figure 4 As shown, the first lid 2221 is screwed to the mounting bracket 24, which is simple and stable to assemble and easy to operate. The lid assembly 22 can be removed or installed by rotating it. Of course, the assembly method of the first lid 2221 and the mounting bracket 24 is not limited to screwing; it can also be a detachable assembly method such as snap-fitting.

[0237] In one implementation, such as Figure 10 and Figure 11 As shown, the movable cover 223 is rotatably connected to the second cover 2222. The movable cover 223 can switch between a closed position and an open position by rotating relative to the second cover 2222.

[0238] Furthermore, such as Figure 7 , Figure 8 and Figure 11 As shown, the second lid 2222 is equipped with a spout 22222. When the user needs to pour water, the detachable kettle 2 is removed, the movable lid 223 is rotated to the open position, opening the spout 2224. The detachable kettle 2 is tilted, and since the spout 22222 is connected to the spout 2224, the water in the kettle cavity 21 flows sequentially through the spout 2224 and the spout 22222 before flowing into the user's water cup. When the movable lid 223 is in the closed position, it seals the spout 22222 to prevent it from being contaminated by external dirt, maintaining its cleanliness and ensuring safe drinking water.

[0239] Furthermore, such as Figure 4 and Figure 8 As shown, the second cover 2222 has a mounting portion 22221, and the movable cover 223 is rotatably connected to the mounting portion 22221. The lid assembly 22 also includes a first elastic element 224, which abuts against the movable cover 223 and the second cover 2222 respectively. The first elastic element 224 and the spout 22222 are located on opposite sides of the mounting portion 22221. Figure 7 , Figure 11 As shown, when the movable cover 223 rotates to the open position under external force, the end of the movable cover 223 opposite to the spout 22222 tilts up to open the water outlet 2224, and the end of the movable cover 223 opposite to the first elastic element 224 is pressed down to compress the first elastic element 224 and store energy. Figure 4 As shown, when the external force is removed, the first elastic element 224 rebounds to drive the movable lid 223 back to the closed position. Furthermore, the first elastic element 224 applies a supporting force to the movable lid 223, so that the end of the movable lid 223 opposite to the spout 22222 can be stably placed on the spout 22222. That is, it helps to keep the movable lid 223 in the closed position and prevents the movable lid 223 from shaking when the detachable kettle 2 is shaken under external force, thus avoiding possible leakage, dirt falling into the kettle cavity 21, and other undesirable phenomena.

[0240] Furthermore, such as Figure 4 As shown, the first elastic element 224 is a spring, which has a simple structure.

[0241] In one implementation, such as Figure 4 and Figure 7 As shown, the first cover 2221 is provided with a first through hole 22211, and the second cover 2222 is provided with a second through hole 22223. The first through hole 22211 and the second through hole 22223 cooperate to form a water outlet 2224. The first through hole 22211 and the second through hole 22223 can be connected to each other to form a water outlet 2224, or the first through hole 22211 and the second through hole 22223 can be matched so that the second through hole 22223 directly constitutes the water outlet 2224. For example, the end surfaces of the first through hole 22211 and the second through hole 22223 facing the end of the kettle cavity 21 are flush, or the end surface of the second through hole 22223 facing the end of the kettle cavity 21 extends to the outside of the first through hole 22211. In this way, the first through hole 22211 and the second through hole 22223 can be matched so that the second through hole 22223 directly constitutes the water outlet 2224.

[0242] In one implementation, such as Figure 4 and Figure 7As shown, the movable lid 223 has a third through hole 2231. When the movable lid 223 is in the closed position, the outlet 2224 communicates with the third through hole 2231 to form a vent 221. When the kettle cavity 21 exhausts gas, the gas is discharged to the outside through the outlet 2224 and the third through hole 2231 in sequence. In this solution, the existing outlet 2224 is used to form part of the structure of the vent 221, reducing the number of openings on the fixed lid 222, reducing the risk of leakage, reducing the impact of the openings on the structural strength of the fixed lid 222, simplifying the structure of the lid assembly 22, facilitating processing, and reducing processing costs. Of course, the configuration of the vent 221 is not limited to the above solution, such as... Figures 15 to 18 As shown, the vent 221 can also be directly set on the fixed cover 222, without the need to open a hole in the movable cover 223.

[0243] In one implementation, such as Figure 4 As shown, when the movable cover 223 is in the closed position, the outlet 2224 and the movable cover 223 are sealed by the third seal 225 to ensure that the detachable kettle 2 is in a sealed state.

[0244] In one implementation, such as Figure 4 and Figure 7 As shown, when the movable cover 223 is in the closed position, the first through hole 22211, the second through hole 22223, and the third through hole 2231 cooperate in sequence to form a vent 221. Specifically, the first through hole 22211 and the second through hole 22223 cooperate to form a water outlet 2224, and the water outlet 2224 communicates with the third through hole 2231 to form a vent 221.

[0245] Furthermore, such as Figure 4 As shown, when the movable cover 223 is in the closed position, the second through hole 22223 and the third through hole 2231 are sealed by the third seal 225 to ensure that the detachable kettle 2 is in a sealed state.

[0246] In one implementation, such as Figure 4 and Figure 7 As shown, the inner wall of the movable cover 223 is provided with a first protrusion 2232, and a third sealing element 225 is engaged at the end of the first protrusion 2232. When the movable cover 223 is in the closed position, the third sealing element 225 is pressed against the outer end port of the outlet 2224. The third sealing element 225 cooperates with the first protrusion 2232 to seal the outer end port of the outlet 2224. In this design, the third sealing element 225 is sleeved on the first protrusion 2232, which is convenient for installation. Furthermore, since the first protrusion 2232 is located on the movable cover 223, if the sealing performance of the third sealing element 225 fails, the movable cover 223 can be rotated to the open position to replace the third sealing element 225.

[0247] Furthermore, such as Figure 4 and Figure 7 As shown, the first protrusion 2232 has a third through hole 2231, which penetrates the movable cover 223. When the movable cover 223 is in the closed position, the first through hole 22211, the second through hole 22223, and the third through hole 2231 cooperate in sequence to form a vent 221. Thus, the third sealing element 225 is used to seal the water outlet 2224 on the one hand, and on the other hand, to seal the connection between the water outlet 2224 and the third through hole 2231, ensuring the airtightness of the connection between the two.

[0248] In one implementation, such as Figure 4 and Figure 7 As shown, the first cover 2221 is provided with a first annular post 22216, and the first annular post 22216 forms a first through hole 22211; the second cover 2222 is provided with a second annular post 22227, and the second annular post 22227 forms a second through hole 22223; the first annular post 22216 is sleeved on the outer periphery of the second annular post 22227, and the two are sealed by a first sealing member 2223 to prevent water and gas in the pot cavity 21 from overflowing outward from between the first through hole 22211 and the second annular post 22227.

[0249] In one implementation, such as Figure 1 , Figure 4 and Figure 8 As shown, the second cover 2222 is provided with a first groove 22224. When the movable cover 223 is in the closed position, the movable cover 223 is embedded in the first groove 22224.

[0250] In one implementation, such as Figure 4 , Figure 6 and Figure 7As shown, the first cover 2221 has a first annular extension 22212, and the mounting bracket 24 has a second annular extension 241. The outer wall of the first annular extension 22212 has a first slot 222121 and a first threaded structure 222122 arranged sequentially in the direction toward the pot cavity 21. The inner wall of the second annular extension 241 has a second slot 2411 and a second threaded structure 2412 arranged sequentially in the direction toward the pot cavity 21. The first threaded structure 222122 and the second threaded structure 2412 are screwed together so that the first cover 2221 is assembled onto the mounting bracket 24. The first slot 222121 and the second slot 2411 are opposite to each other and form a snap-fit ​​cavity. The second seal 25 is snapped into the snap-fit ​​cavity. The second seal 25 is installed on the side away from the pot cavity 21 at the screw connection between the first cover 2221 and the mounting bracket 24. On the one hand, it avoids the second seal 25 from interfering with the assembly of the first cover 2221 and the mounting bracket 24. On the other hand, the screw connection between the first cover 2221 and the mounting bracket 24 plays a rough sealing role. Then, the sealing performance is improved by the sealing of the second seal 25.

[0251] Furthermore, such as Figure 4 and Figure 6 As shown, since the first annular extension 22212 and the second annular extension 241 are assembled by screwing, a second gap 261 is formed between the end of the first annular extension 22212 and the second annular extension 241. Figure 6 and Figure 7 As shown, the end of the first annular extension 22212 is provided with a water passage hole 222123. When the detachable kettle 2 is poured, the water in the second gap 261 flows to the outlet 2224 through the water passage hole 222123. During the pouring process, the water flow can be prevented from being unable to drain due to the accumulation in the second gap 261. This helps the user to remove all the water in the kettle cavity 21, reduce or avoid residual water, and promote healthy drinking.

[0252] Furthermore, such as Figure 4 and Figure 6 As shown, the second annular extension 241 extends at least partially into the pot body 23. To reduce the precision requirements of the assembly between the mounting bracket 24 and the pot body 23, a third gap 262 is formed between the second annular extension 241 and the inner wall of the pot body 23. Figure 6 and Figure 7As shown, the end of the second annular extension 241 is provided with a notch 2413. When the detachable kettle 2 is filled with water, the water in the third gap 262 flows sequentially through the notch 2413, the second gap 261, and the water passage hole 222123 to the outlet 2224. During the pouring process, water accumulation in the third gap 262 can be avoided, preventing water from being unable to drain. In this design, the water in the third gap 262 can be smoothly drained through the notch 2413, the second gap 261, and the water passage hole 222123, which helps the user to remove all the water from the kettle cavity 21, reducing or avoiding residual water and promoting healthy drinking.

[0253] Furthermore, such as Figure 6 and Figure 7 As shown, in the radial direction of the second annular extension 241, the notch 2413 is positioned opposite to the water passage hole 222123. In this way, the distance between the notch 2413 and the water passage hole 222123 is relatively short, which is conducive to the rapid pouring out of the water in the third gap 262.

[0254] In one implementation, such as Figure 3 , Figure 4 and Figure 7 As shown, the mounting bracket 24 also includes a third slot 242, which engages with the open end of the pot body 23. When assembling the mounting bracket 24 onto the pot body 23, the third slot 242 is first engaged with the open end of the pot body 23 to achieve pre-positioning, and then it is fixed by induced welding for sealing, which facilitates operation.

[0255] In one implementation, such as Figure 4 , Figure 6 and Figure 7 As shown, the inner wall of the first cover 2221 is provided with a diversion rib 22213. The diversion rib 22213 is connected to the inner wall of the first cover 2221 and forms a diversion hole 22214. When the user pours water, the water flow is divided into two streams by the diversion rib 22213. One stream flows directly to the outlet 2224 without passing through the diversion hole 22214, while the other stream flows to the outlet 2224 after passing through the diversion hole 22214. In this design, by setting the diversion rib 22213, the water flow is divided into two streams when the user pours water. A small amount of air enters between the two streams, which can slow down the flow rate to a certain extent, thereby reducing water flow noise.

[0256] Furthermore, such as Figure 4 and Figure 8 As shown, the diversion hole 22214 is located on the side of the first through hole 22211 away from the spout 22222 of the second cover body 2222. In this way, when the user pours water, more water can flow through the diversion rib 22213, thus improving the noise reduction effect.

[0257] In one implementation, such as Figure 1 and Figure 8 As shown, the detachable kettle 2 is installed on the main unit 1 along a first direction. The kettle body 23 includes a handle 231, which is spaced apart from the spout 22222 along the first direction. The movable lid 223 extends along the first direction in its length direction and has a long strip structure, making it simple and compact. In one specific embodiment, the first direction is from front to back along the main unit 1. The detachable kettle 2 is installed on the front surface of the main unit 1 from the front, and the movable lid 223 extends along the front-back direction in its length direction. Of course, the installation direction of the detachable kettle 2 is not limited to front to back; it can also be installed on the main unit 1 along the left-right direction or along the up-down direction. Preferably, to suit the user's usage habits, the detachable kettle 2 is installed on the main unit 1 along the front-back direction.

[0258] For ease of explanation, the following text will use "the first direction is the direction from front to back along host 1" as an example for specific explanation.

[0259] In one implementation, such as Figure 4 and Figure 7 As shown, the detachable kettle 2 also includes a valve assembly 226, which is located in the vent 221. When the detachable kettle 2 is installed on the main unit 1, the valve assembly 226 is in the open state to open the vent 221; when the detachable kettle 2 is removed from the main unit 1, the valve assembly 226 is in the closed state to close the vent 221. This solution controls the opening and closing of the vent 221 through the valve assembly 226, which is simple in structure, easy to operate, and the vent 221 is small in size, making it less prone to dust and impurities entering.

[0260] Furthermore, such as Figure 1 , Figure 4 and Figure 7 As shown, the valve assembly 226 includes a valve core 2261 and a second elastic element 2262. The valve core 2261 is movably installed in the vent 221. One end of the second elastic element 2262 abuts against the valve core 2261, and the other end abuts against the abutment platform inside the vent 221. When the detachable kettle 2 is installed on the main unit 1, the valve core 2261 is in the open position to open the vent 221. The detachable kettle 2 is in a non-sealed state, and the airflow in the kettle cavity 21 can be discharged through the vent 221, or external airflow can enter the kettle cavity 21 through the vent 221 to maintain the air pressure balance in the kettle cavity 21. At this time, the second elastic element 2262 is compressed by the valve core 2261, is in a compressed state, and stores energy. Figure 10As shown, when the detachable kettle 2 is detached from the main unit 1, the second elastic element 2262 can rebound, and the rebound force drives the valve core 2261 to move to the closed position to close the vent 221, so that the detachable kettle 2 is in a sealed state. In one specific embodiment, as... Figure 1 , Figure 4 , Figure 7 , Figure 10 and Figure 11 As shown, the vent 221 is located on the top wall of the detachable kettle 2. The valve core 2261 moves vertically along the main unit 1 to switch between an open and closed position. Of course, the movement direction of the valve core 2261 is not limited to moving upwards along the main unit 1; the valve core 2261 can also be installed on the side of the detachable kettle 2 facing the main unit 1. In this way, the valve core 2261 can switch between an open and closed position along the front-back or left-right direction of the main unit 1. Furthermore, the second elastic element 2262 is a spring, which has a simple structure.

[0261] Furthermore, such as Figure 4 and Figure 7 As shown, valve assembly 226 also includes a valve core sealing ring 2263. When valve core 2261 is in the open position, a vent gap is maintained between valve core sealing ring 2263 and the wall of vent 221, allowing airflow in the kettle cavity 21 to be discharged or external airflow to enter the kettle cavity 21. When valve core 2261 is in the closed position, valve core sealing ring 2263 is press-fitted with the wall of vent 221 to close vent 221, thus sealing the detachable kettle 2.

[0262] In one implementation, such as Figure 10 As shown, during the installation of the detachable kettle 2 onto the main unit 1, the distance between the first trigger structure 111 and the valve core 2261 on the main unit 1 gradually decreases until the valve core 2261 contacts the first trigger structure 111. Then, the valve core 2261 moves under the pressure of the first trigger structure 111 until it moves to the open position, and as... Figure 4 As shown, during the movement of the valve core 2261, the valve core 2261 compresses the second elastic element 2262. For example... Figure 10As shown, when the detachable kettle 2 is detached from the main unit 1, the valve core 2261 disengages from the first trigger structure 111. That is, the pressure applied by the first trigger structure 111 to the valve core 2261 is removed, and the second elastic element 2262 rebounds, driving the valve core 2261 to move to the closed position. In one specific embodiment, the valve core 2261 is located on the top wall of the detachable kettle 2. The open position of the valve core 2261 is lower than its closed position. The valve core 2261 moves downward to move from the closed position to the open position. That is, during the process of installing the detachable kettle 2 onto the main unit 1, the valve core 2261 moves downward under the pressure of the first trigger structure 111 until it reaches the open position during movement.

[0263] Furthermore, such as Figure 2 and Figure 10 As shown, the first trigger structure 111 is a protruding structure, and the first trigger structure 111 has a first guide slope 1111 and a first abutment surface 1112. The detachable kettle 2 is installed on the main unit 1 along a first direction (along the front-to-back direction of the main unit 1), and the first guide slope 1111 extends obliquely in the first direction toward the detachable kettle 2. Figure 4 and Figure 10 As shown, during the installation of the detachable kettle 2 onto the main unit 1, the valve core 2261 moves along with the detachable kettle 2 until it contacts the first guide slope 1111. Since the detachable kettle 2 continues to move along the first direction, the valve core 2261 will press against the first guide slope 1111, while the first trigger structure 111 does not move. Consequently, the valve core 2261 will slide along the first guide slope 1111. Simultaneously, the movement direction of the valve core 2261 is restricted by the vent 221, causing the valve core 2261 to move towards the kettle cavity 21 until it reaches the open position, at which point the vent 221 opens. That is, in this solution, the first trigger structure 111 directly drives the valve core 2261 to move towards the open position via the first guide slope 1111. Figure 4 As shown, when the valve core 2261 moves to the open position, it remains in the open position under the pressure of the first contact surface 1112. In this design, the first triggering structure 111 is simple in structure, requires minimal modification to the main unit 1, which helps reduce modification costs. The triggering process for opening and closing the vent 221 is simple and smooth, and the phenomenon of unsuccessful triggering is unlikely to occur.

[0264] In one implementation, such as Figure 4 and Figure 7 As shown, the valve assembly 226 is mounted on the lid assembly 22 of the detachable kettle 2, as... Figure 11 As shown, when the valve core 2261 is in the closed position, the valve core 2261 extends partially beyond the lid assembly 22, thus, as Figure 10As shown, during the installation of the detachable kettle 2 onto the main unit 1, the valve core 2261 can contact the first trigger structure 111, thereby switching from the closed position to the open position. Figure 1 and Figure 9 As shown, the outer wall of the kettle lid assembly 22 is provided with a protective protrusion 2233. The protective protrusion 2233 at least partially surrounds the valve core 2261. The valve core 2261 does not protrude from the protective protrusion 2233. In this way, when the detachable kettle 2 is removed from the main unit 1, the protective protrusion 2233 can play a certain protective role for the valve core 2261, preventing the user from accidentally touching the valve core 2261 and causing the valve core 2261 to switch to the open state, resulting in water leakage.

[0265] Furthermore, the detachable kettle 2 is installed on the main unit 1 along the first direction (the direction from front to back along the main unit 1), such as... Figure 1 and Figure 9 As shown, the protective protrusion 2233 is an open annular shape, and the openings 22331 of the valve core 2261 and the protective protrusion 2233 are distributed sequentially along the first direction, as shown. Figure 9 and Figure 10 As shown, during the installation of the detachable kettle 2 onto the main unit 1, the first trigger structure 111 passes through the opening 22331 and presses against the valve core 2261. In this design, during the installation of the detachable kettle 2, the opening 22331 serves to avoid contact, allowing the valve core 2261 to smoothly contact the first trigger structure 111.

[0266] Furthermore, such as Figure 4 and Figure 7 As shown, the first through hole 22211 of the first cover 2221 mates with the second through hole 22223 of the second cover 2222 to form a water outlet 2224. The water outlet 2224 mates with the third through hole 2231 of the movable cover 223 to form a vent 221. Figure 9 and Figure 11 As shown, when the valve core 2261 is in the closed position, the valve core 2261 extends partially out of the third through hole 2231, and the protective protrusion 2233 is provided on the outer wall of the movable cover 223.

[0267] In one implementation, such as Figure 4 and Figure 7 As shown, the detachable kettle 2 also includes a locking element 27, which moves to switch between a locked position and an unlocked position. When the user does not need to take water, the locking element 27 is in the locked position, locking the lid assembly 22 to the kettle body 23 to ensure that the lid assembly 22 is closed stably. When the locking element 27 moves to the unlocked position, the locking element 27 is unlocked, and the user can take water.

[0268] Furthermore, such as Figure 4 and Figure 7 As shown, the kettle lid assembly 22 includes a fixed lid body 222 and a movable lid body 223, with a locking element 27 movably mounted on the movable lid body 223. When the locking element 27 is in the locked position, it is restricted by the fixed lid body 222 to prevent the movable lid body 223 from moving to the open position, thus closing the water outlet 2224 and preventing leakage. In this way, the detachable kettle 2 can be placed at any angle to meet the storage needs of different scenarios.

[0269] Furthermore, such as Figure 4 As shown, the locking element 27 has a limiting part 272. The limiting part 272 and the fixed cover 222 cooperate through a limiting hole and a limiting protrusion to limit the movement of the locking element 27 along the opening direction of the movable cover 223. The locking structure is simple. Alternatively, the limiting part 272 can be a limiting hole and the fixed cover 222 can have a limiting protrusion; or the limiting part 272 can be a limiting protrusion and the fixed cover 222 can have a limiting hole. Of course, the limiting hole can be a through hole or a blind hole.

[0270] Furthermore, such as Figure 4 , Figure 7 and Figure 8 As shown, the fixed cover 222 has a limiting hole 22226, and the limiting part 272 is a limiting protrusion. When the locking element 27 is in the locked position, the limiting part 272 is inserted into the limiting hole 22226 to limit the movement of the locking element 27 along the opening direction of the movable cover 223, thereby locking the movable cover 223 and closing the water outlet 2224. Figure 7 , Figure 11 As shown, when the locking element 27 moves to the point where the limiting part 272 disengages from the limiting hole 22226, the locking element 27 is in the open position, and the movable cover 223 can move to open the water outlet 2224, allowing the user to take water.

[0271] In one implementation, such as Figure 11 As shown, the locking element 27 is located on the side of the second through hole 22223 opposite to the spout 22222, preventing water from flowing through the locking element 27 when the user pours water. This prevents water from contaminating the locking element 27 and also prevents water from accumulating on its surface, thus avoiding a wet finger experience when the user moves the locking element 27. Furthermore, as... Figure 8 As shown, a baffle 22228 is provided between the second through hole 22223 and the limiting hole 22226 to prevent water from contacting the locking element 27 when water is discharged from the outlet 2224.

[0272] In one implementation, such as Figure 9 As shown, the movable cover 223 is provided with a fourth limiting structure 2235. (As...) Figure 9and Figure 10 As shown, when the locking element 27 is in the locked position, the fourth limiting structure 2235 restricts the locking element 27 from disengaging from the locked position, so that the locking element 27 can be stably kept in the locked state; as Figure 9 and Figure 11 As shown, when the force applied to the locking element 27 exceeds a preset value, the locking element 27 disengages from the restriction of the fourth restriction structure 2235. Furthermore, the fourth restriction structure 2235 is a protrusion. When the locking element 27 is in the locked position, the fourth restriction structure 2235 abuts against the locking element 27. When the applied force exceeds the preset value, the locking element 27 can smoothly pass over the fourth restriction structure 2235 under this force, thus releasing the lock.

[0273] In one implementation, such as Figure 4 and Figure 9 As shown, the movable cover 223 has a sixth through hole 2236. The locking element 27 includes a limiting part 272, a connecting part 273, and an operating part 274 connected in sequence. The limiting part 272 passes through the sixth through hole 2236. The limiting part 272 is located inside the movable cover 223 to lock the movable cover 223. The operating part 274 is located outside the movable cover 223. External force pushes the operating part 274 to switch the locking element 27 between the locked position and the unlocked position. In this solution, the locking element 27 has a simple structure, and the assembly structure of the locking element 27 with the movable cover 223 and the fixed cover 222 is simple, which helps to reduce processing costs.

[0274] Furthermore, such as Figure 1 , Figure 4 and Figure 9 As shown, the outer wall of the movable cover 223 is provided with a second groove 2237, and the operating part 274 is at least partially embedded in the second groove 2237 to prevent the operating part 274 from protruding too much from the movable cover 223 and affecting the appearance of the lid assembly 22.

[0275] Furthermore, such as Figure 1 , Figure 4 and Figure 9 As shown, the groove wall of the second groove 2237 is configured to guide the locking element 27 to move between the locked position and the unlocked position. Specifically, the peripheral outer contour of the locking element 27 contacts the groove wall of the second groove 2237 with a clearance fit, so that the locking element 27 can smoothly switch between the locked position and the unlocked position, and the groove wall of the second groove 2237 guides the movement direction of the locking element 27, so that the locking element 27 can only move between the locked position and the unlocked position.

[0276] In one implementation, such as Figure 4 and Figure 9As shown, the operating part 274 includes a connected plate 2741 and an operating protrusion 2742. The plate 2741 is movably embedded in the second groove 2237, and the operating protrusion 2742 is located outside the second groove 2237. In this design, the plate 2741 and the operating protrusion 2742 cooperate to form the operating part 274. This allows the size of the operating protrusion 2742 to be minimized, reducing the probability of accidental contact. At the same time, the size of the plate 2741 can be increased to a certain extent to ensure the structural strength of the operating part 274 and improve the service life of the locking element 27.

[0277] In one implementation, such as Figure 1 and Figure 14 As shown, the detachable kettle 2 is installed on the front side of the main unit 1 from front to back, conforming to the user's usage habits. The front side of the housing 11 of the main unit 1 has a recess 113, in which the detachable kettle 2 is partially embedded. By partially wrapping the detachable kettle 2 with the front side of the housing 11, the installation stability of the detachable kettle 2 can be improved, and the size of the detachable kettle 2 protruding from the housing 11 can be reduced, thereby improving the aesthetic appearance of the water purification equipment 100.

[0278] In one implementation, such as Figure 1 , Figure 4 and Figure 7 As shown, the water inlet 234 and the handle 231 are respectively located on the radial sides of the kettle body 23. Specifically, as... Figure 3 and Figure 5 As shown, the kettle body water inlet 234 is used to connect to the water circuit of the main unit 1. In this solution, the handle 231 is set on the side of the kettle body 23 away from the kettle body water inlet 234, so that the user can hold the handle 231, align the kettle body water inlet 234 with the main unit 1, and then install the detachable kettle 2 onto the main unit 1.

[0279] Furthermore, such as Figure 5 As shown, the water inlet 234 of the kettle body is located near the bottom of the kettle body 23. When the main unit 1 supplies water to the detachable kettle 2, the clean water enters the kettle cavity 21 from the water inlet 234 of the kettle body, and then the water level gradually rises. This avoids the water from falling onto the bottom wall of the kettle cavity 21 when it enters the kettle cavity 21 from a high place, which would produce an impact sound and cause loud noise.

[0280] In one implementation, such as Figure 1 and Figure 5 As shown, the main unit 1 is equipped with a sterilization lamp assembly 16, and the detachable kettle 2 is provided with a light-transmitting structure 233; the sterilization light emitted by the sterilization lamp assembly 16 of the main unit 1 enters the kettle cavity 21 through the light-transmitting structure 233 to sterilize the water in the kettle cavity 21 and ensure healthy drinking.

[0281] Furthermore, such as Figure 5 As shown, the light-transmitting structure 233 extends at least partially into the pot cavity 21, further improving the uniformity of the sterilization light distribution entering the pot cavity 21. The end of the light-transmitting structure 233 extending into the pot cavity 21 is hemispherical, further improving the uniformity of the sterilization light distribution entering the pot cavity 21.

[0282] In one implementation, such as Figure 1 and Figure 5 As shown, the sterilization lamp assembly 16 includes a sterilization lamp 161, a lamp cover 162, and a mounting base 163. The sterilization lamp 161 is mounted on the lamp cover 162, the lamp cover 162 is mounted on the mounting base 163, and the mounting base 163 is mounted on the housing 11 of the main unit 1. The lamp cover 162 covers the sterilization lamp 161, which serves two purposes: firstly, it disperses the light emitted by the sterilization lamp 161; secondly, it protects the sterilization lamp 161 from dust. Furthermore, considering light transmission and portability, the lamp cover 162 is typically made of glass or plastic, which has relatively weak structural strength. This solution replaces the lamp cover 162 with the mounting base 163 for fixing it to the housing 11. By increasing the structural strength of the mounting base 163, the stability of the assembly between the sterilization lamp assembly 16 and the housing 11 is improved.

[0283] Furthermore, such as Figure 5 As shown, the end of the lampshade 162 facing the light-transmitting structure 233 is hemispherical, which helps the light emitted by the sterilization lamp 2261 to enter the chamber 21 more evenly.

[0284] In one implementation, such as Figures 1 to 4 As shown, the valve assembly 226 is located on the top wall of the detachable kettle 2. The main unit 1 is provided with a housing 11, and the housing 11 is provided with an outer protruding shell portion 112. The outer protruding shell portion 112 is located above the detachable kettle 2. The first trigger structure 111 is located on the bottom wall of the outer protruding shell portion 112. The outer protruding shell portion 112 can cover the kettle lid assembly 22 of the detachable kettle 2, which plays a certain role in dust prevention.

[0285] Furthermore, such as Figure 3 As shown, the convex shell portion 112 is provided with a receiving cavity 1121, which is used to increase the accommodating space of the housing 11, for example, it can be used to store the control board 18 of the main unit 1.

[0286] In one implementation, such as Figure 12As shown, the main unit 1 includes a filter element assembly 12, which is located within the housing 11. The filter element assembly 12 includes a first filter element 121, a second filter element 122, and a third filter element 123 arranged sequentially along the water flow direction. The first filter element 121, the second filter element 122, and the third filter element 123 are arranged in an L-shape, forming a receiving space 13 between the filter element assembly 12 and the inner wall of the housing 11. The remaining components of the main unit 1 can be housed within the receiving space 13, making the internal space arrangement of the main unit 1 more compact and improving space utilization. Of course, the arrangement of the first filter element 121, the second filter element 122, and the third filter element 123 is not limited to an L-shape. For example, the first filter element 121, the second filter element 122, and the third filter element 123 can also be arranged in an isosceles triangle, with the remaining components of the main unit 1 distributed around the filter element assembly 12.

[0287] The first filter element 121 is a polypropylene activated carbon composite filter element, used to intercept large particles of sediment and rust, adsorb discoloration and odor, and remove residual chlorine; the second filter element 122 is a reverse osmosis membrane filter element, used to remove harmful substances such as heavy metals, bacteria, viruses, microorganisms, nitrates, chloroform, and carbon tetrachloride from the water; the third filter element 123 is an activated carbon water purification composite filter element, used to inhibit microorganisms and improve taste.

[0288] Furthermore, such as Figure 12 As shown, the main unit 1 also includes a power pump 14 (such as a booster pump or a diaphragm pump), which provides power for the water flow through the filter element assembly 12; the power pump 14 is located at least partially in the housing space 13, which facilitates the compact arrangement of the power pump 14 and the filter element assembly 12.

[0289] Furthermore, such as Figure 3 and Figure 12 As shown, the main unit 1 also includes a water storage box 15, through which the purified water provided by the filter element assembly 12 is supplied to the detachable kettle 2; the water storage box 15 is located in the receiving space 13, and the filter element assembly 12 is arranged around the water storage box 15, which is conducive to the compact arrangement of the water storage box 15 and the filter element assembly 12.

[0290] Furthermore, such as Figure 3 , Figure 5 and Figure 12 As shown, the water storage box 15 includes a cylindrical main body box 151. The cross-sectional dimension of the cylindrical main body box 151 is smaller than the cross-sectional dimension of the pump body of the power pump 14. The water storage box 15 is vertically arranged between the filter element assembly 12 and the power pump 14, which maximizes the rationality of the positional relationship between the water storage box 15, the filter element assembly 12, and the power pump 14, improves space utilization, and is conducive to the miniaturization design of the main unit 1.

[0291] In one implementation, such as Figure 3 , Figure 5 and Figure 13As shown, the water storage box 15 includes a box inlet 152, a box outlet 153, and a drain valve 154. The box inlet 152 is used to introduce clean water, and the drain valve 154 is located in the box outlet 153. When the detachable kettle 2 is installed on the main unit 1, the drain valve 154 is opened, allowing fluid communication between the box outlet 153 and the detachable kettle 2; when the detachable kettle 2 is removed from the main unit 1, the drain valve 154 is closed to prevent water leakage from the main unit 1.

[0292] Furthermore, the inlet 152 of the housing is connected to the outlet of the filter element assembly 12. The purified water after being purified by the filter element assembly 12 first enters the water storage box 15 through the inlet 152 of the housing, and then flows into the detachable water bottle 2 through the outlet 153 of the housing.

[0293] Furthermore, such as Figure 13 As shown, the water storage box 15 also includes a one-way valve 155, which is located in the water inlet 152 of the box body to prevent water in the water storage box 15 from flowing out of the water inlet 152. Specifically, when the filter element assembly 12 is flushed, there will be negative pressure in the water path, which will cause water in the water storage box 15 to flow back into the filter element assembly 12. In order to avoid backflow, the prior art usually sets the water inlet of the box body at the top of the water storage box, so that the water supplied by the filter element assembly is injected from the top of the water storage box, forming an air gap, thereby preventing the negative pressure during flushing from causing water in the water storage box to flow back into the filter element assembly. This solution is limited by space and has a relatively complex structure. This solution sets a one-way valve 155 in the water inlet 152 of the box body. When flushing the water path, the one-way valve 155 can prevent water in the water storage box 15 from being drawn back.

[0294] In one implementation, such as Figure 5 and Figure 13 As shown, the water storage box 15 includes a buffer chamber 156. When the detachable water bottle 2 is installed on the main unit 1, the buffer chamber 156 is connected to the water inlet 152 and the water outlet 153 of the box body respectively. The buffer chamber 156 plays the role of buffering fluid, which helps the main unit 1 to stably supply water to the detachable water bottle 2.

[0295] Furthermore, such as Figure 5 and Figure 13As shown, the bottom wall of the buffer chamber 156 is provided with a third groove 1561. The length of the third groove 1561 extends toward the water outlet 153 of the box body, and the water outlet 153 of the box body is at least partially opposite to the position of the third groove 1561. The drain valve 154 can be switched to the open state under external force. When the main unit 1 is tilted, the third groove 1561 is used to guide the water flow out from the water outlet 153 of the box body. Specifically, after the water purification equipment 100 undergoes a complete water test, it needs to be drained. There are usually two existing drainage methods: one is to blow with an air gun, which does not drain the water completely; the other is to open a drain outlet, which requires an additional drain outlet and corresponding water circuit configuration, making the structure relatively complex. In this solution, by utilizing the water outlet 153 of the water storage box 15, there is no need to set up an additional drain outlet. Users can open the drain valve 154 by using tools or manually pressing it. By tilting the main unit 1, the water in the water storage box 15 will flow out due to gravity. Furthermore, by optimizing the structure of the buffer chamber 156, the third groove 1561 is used as the low position for water storage in the water storage box 15, and the length of the third groove 1561 extends towards the water inlet 152 of the box and is positioned opposite the water outlet 153 of the box, which is conducive to completely or as completely as possible draining the remaining water in the water storage box 15.

[0296] In one implementation, such as Figure 5 and Figure 13 As shown, the cylindrical main body box 151 has a cavity 1511; the cavity 1511 is located above the buffer cavity 156, and a water level detection element 1512 is provided in the cavity 1511. Specifically, when the detachable kettle 2 is installed on the main unit 1, the kettle cavity 21, the buffer cavity 156, and the cavity 1511 are connected in sequence. In this way, by obtaining the water level information in the cavity 1511, it can be determined whether the water level in the kettle cavity 21 has reached the preset position. It is not necessary to set the water level detection element 1512 on the detachable kettle 2, which simplifies the detachable kettle 2 and eliminates the need to supply power to the detachable kettle 2 for water level detection. The water level detection element 1512 can be a float, and a water level sensor (not shown in the figure) is installed on the outer wall of the water storage box 15. The water level sensor cooperates with the float to obtain the water level information in the cavity 1511.

[0297] In one implementation, such as Figure 1 and Figure 5 As shown, the housing 11 includes a mounting plate 114 and a main body shell 115, with the mounting plate 114 mounted on the main body shell 115. The water outlet 153 is mounted on the mounting plate 114 and partially extends out of the housing 11. This design, by adding the mounting plate 114 and increasing its structural strength, improves the stability of the assembly between the water storage box 15 and the housing 11.

[0298] Furthermore, such as Figure 1 and Figure 5As shown, the sterilization lamp assembly 16 is mounted on the mounting plate 114, reducing the number of openings on the main body shell 115, ensuring the structural stability of the main body shell 115, and reducing the processing cost of the main body shell 115. In one specific embodiment, the mounting base 163 of the sterilization lamp assembly 16 is mounted on the mounting plate 114.

[0299] In one implementation, such as Figure 1 and Figure 2 As shown, the main unit 1 is provided with a first guide structure 171, and the detachable kettle 2 is provided with a second guide structure 232. The first guide structure 171 and the second guide structure 232 cooperate to guide the detachable kettle 2 to be installed on the main unit 1, or to guide the detachable kettle 2 to be removed from the main unit 1. Specifically, this solution, by adding the first guide structure 171 and the second guide structure 232, enables the first trigger structure 111 on the main unit 1 to accurately trigger the opening and closing of the vent 221 of the detachable kettle 2. In a specific embodiment, the first guide structure 171 and the second guide structure 232 cooperate to enable the first trigger structure 111 on the main unit 1 to accurately trigger the valve core 2261 to switch between the open and closed positions, reducing the difficulty of manual alignment, making the installation and removal of the detachable kettle 2 easier, and preventing water leakage caused by the detachable kettle 2 not being inserted properly, thus improving the user experience.

[0300] Furthermore, such as Figure 1 and Figure 2 As shown, the length of both the first guide structure 171 and the second guide structure 232 extends along the front-to-back direction of the main unit 1. When the detachable kettle 2 is installed on the main unit 1 in the front-to-back direction, the first guide structure 171 and the second guide structure 232 work together to extend the guide path and improve the guide efficiency.

[0301] Furthermore, such as Figure 2 As shown, the second guide structure 232 is an axisymmetric structure with a first axis of symmetry. The kettle cavity 21 has a second axis of symmetry extending along the front-rear direction of the main unit 1. The first axis of symmetry and the second axis of symmetry are on a vertical plane. In this way, during the cooperation between the first guide structure 171 and the second guide structure 232, the center of gravity of the detachable kettle 2 can fall on the second guide structure 232 as much as possible, making it easier for the user to push the detachable kettle 2.

[0302] In one implementation, such as Figure 1 and Figure 2 As shown, the first guide structure 171 is a protruding structure, and the second guide structure 232 is a sliding groove structure; when the detachable kettle 2 is installed on or removed from the main unit 1, the first guide structure 171 moves along the second guide structure 232.

[0303] Furthermore, such as Figure 1 and Figure 2 As shown, the first guide structure 171 is located on the outside of one side of the housing 11, and the first end face 1711 of the first guide structure 171 facing away from the housing 11 is arc-shaped. When the second guide structure 232 contacts the first end face 1711 at its opening end 2321 facing the housing 11, the detachable kettle 2 can be rotated until the second guide structure 232 is aligned with the first guide structure 171 under the cooperation of the opening end 2321 and the first end face 1711. In this way, when the second guide structure 232 is not aligned with the first guide structure 171 immediately, the arc-shaped first end face 1711 can play an alignment assistance role for the second guide structure 232, so that the user can smoothly align the second guide structure 232 with the first guide structure 171 and insert it by swinging the detachable kettle 2, further reducing the difficulty of inserting the detachable kettle 2.

[0304] Furthermore, such as Figure 1 As shown, the first end face 1711 is semi-circular arc-shaped, so that the first end face 1711 of the first guide structure 171 forms a 180° guiding function, making it more convenient to insert the detachable kettle 2.

[0305] In one implementation, such as Figure 2 As shown, the second guide structure 232 is arc-shaped, facing away from the first side groove wall 2322 of the housing 11; as Figure 1 and Figure 2 As shown, when the detachable kettle 2 is installed on the main unit 1, the first end face 1711 abuts against the first side groove wall 2322. In this way, the abutment between the first side groove wall 2322 and the first end face 1711 limits the insertion position of the detachable kettle 2, preventing the user from inserting it with excessive force, which could cause a violent collision between the detachable kettle 2 and the water connection point of the main unit 1 (e.g., the water outlet 153 of the box), resulting in damage to the main unit 1.

[0306] In one implementation, such as Figure 1 As shown, the host 1 includes a base 17, and a first guide structure 171 is disposed on the base 17. Thus, only the structure of the base 17 needs to be modified, resulting in low modification costs. Furthermore, as... Figure 2 As shown, the second guide structure 232 is provided on the bottom wall of the detachable kettle 2, which can improve the aesthetic appearance of the detachable kettle 2.

[0307] In one implementation, such as Figure 1 and Figure 12As shown, the main unit 1 also includes a raw water tank 19, which stores raw water. The outlet of the raw water tank 19 is connected to the inlet of the filter element assembly 12. When the water purification device 100 starts producing water, the raw water in the raw water tank 19 enters the filter element assembly 12, is filtered by the filter element assembly 12 to form purified water, and the purified water flows into the kettle chamber 21 through the water storage box 15. Of course, the water purification device 100 may also not have a raw water tank 19, and the inlet of the filter element assembly 18 may be directly connected to the municipal tap water supply through a raw water pipe.

[0308] Second Implementation Method

[0309] The following is based on Figures 15 to 18 The water purification device according to the second embodiment of the present invention will be described.

[0310] The water purification device in this embodiment has the same structural parts as the water purification device in the first embodiment. The differences between the two embodiments are mainly described below.

[0311] In this embodiment, such as Figures 15 to 18 As shown, the arrangement of the vent 221 differs from that in the first embodiment. Specifically, the first cover 2221 has a fourth through hole 22215, and the second cover 2222 has a fifth through hole 22225. The fourth through hole 22215 and the fifth through hole 22225 cooperate to form the vent 221. In this solution, the first through hole 22211 of the first cover 2221 cooperates with the second through hole 22223 of the second cover 2222 to form the water outlet 2224. In addition, the first cover 2221 and the second cover 2222 also have additional holes to form the vent 221. The water outlet 2224 and the vent 221 are set separately, eliminating the need to make holes in the movable cover 223 and reducing modifications to the movable cover 223.

[0312] In one implementation, such as Figure 15 and Figure 18 As shown, when the movable cover 223 is in the closed position, it covers the vent 221, reducing the probability of the vent 221 being exposed to the outside environment, which helps improve the cleanliness of the vent 221. Furthermore, to allow the vent 221 to smoothly exhaust air, a first gap 227 is provided between the movable cover 223 and the second cover 2222 when the movable cover 223 is in the closed position. Figure 16 As shown, when the vent 221 is opened, the gas in the pot cavity 21 is discharged through the vent 221 into the space between the movable lid 223 and the fixed lid 222, and then discharged outward through the first gap 227, without the need to open a hole on the movable lid 223 for venting.

[0313] In one embodiment, the triggering of the vent 221 state switching differs from that in the first embodiment. Specifically, as follows: Figure 15and Figure 18 As shown, the detachable kettle 2 is also provided with a second trigger structure 271; the second trigger structure 271 moves to trigger the vent 221 to switch between an open state and a closed state.

[0314] Furthermore, when the detachable kettle 2 switches between the installed state and the detached state, such as Figure 15 and Figure 16 As shown, the second trigger structure 271 is triggered by the first trigger structure 111 provided in the host 1 to move, thereby triggering the vent 221 to switch between an open state and a closed state. The opening and closing of the vent 221 in this solution does not require manual triggering by the user, which is convenient to use and avoids affecting the use of the detachable kettle 2 due to the user forgetting to open or close the vent 221.

[0315] In one embodiment, the second triggering structure 271 is movable under external force to switch between a triggered position and a non-triggered position. For example... Figure 15 and Figure 16 As shown, during the process of the second triggering structure 271 switching from the non-triggering position to the triggering position, the second triggering structure 271 applies a resistance force to the valve core 2261 to drive the valve core 2261 to move to the open position. During this movement, the valve core 2261 compresses the second elastic element 2262 to store energy. When the second triggering structure 271 switches from the triggering position to the non-triggering position, the second triggering structure 271 releases the resistance force on the valve core 2261, and the second elastic element 2262 rebounds, driving the valve core 2261 to move to the closed position.

[0316] Furthermore, the structure of the locking element 27 in this embodiment is slightly different from that in the first embodiment. Specifically, as shown in the figure... Figures 15 to 18 As shown, the second trigger structure 271 is disposed on the locking element 27; the lid assembly 22 is at least partially movable relative to the kettle body 23 to open or close the kettle cavity 21. When the locking element 27 moves, the position of the second trigger structure 271 changes accordingly, switching between a non-triggering position and a triggering position, thereby locking the lid assembly 22 to the kettle body 23 or releasing the lid assembly 22. This solution integrates the second trigger structure 271 onto the locking element 27, reducing the number of parts and the corresponding assembly structure, simplifying the structure of the detachable kettle 2, and reducing manufacturing costs.

[0317] In one embodiment, the non-triggered position includes a first non-triggered position and a second non-triggered position. For example... Figure 15 and Figure 18As shown, when the second trigger structure 271 is in the first non-trigger position, the locking element 27 locks the lid assembly 22, the water outlet 2224 is closed, the user cannot take water, and the valve core 2261 is in the closed position, the vent 221 is closed. At this time, the detachable kettle 2 is in a completely sealed state, and the detachable kettle 2 can be placed at any angle without easily leaking, thus meeting the storage needs of different scenarios. Figure 16 and Figure 18 As shown, when the second trigger structure 271 is in the trigger position, the locking element 27 locks the kettle lid assembly 22, the water outlet 2224 is closed, the user cannot take water, and the valve core 2261 is in the open position, the vent 221 is open, the detachable kettle 2 is in a non-sealed state, and the gas in the kettle cavity 21 can be discharged to the outside through the vent 221, or external gas can enter the kettle cavity 21 through the vent 221. Figure 17 and Figure 18 As shown, when the second trigger structure 271 is in the second non-trigger position, the locking element 27 releases the lock on the lid assembly 22, allowing the user to take water. The valve core 2261 is in the closed position, and the vent 221 is sealed. When the user takes water, the kettle cavity 21 is connected to the outside through the water outlet 2224 to maintain the air pressure balance within the kettle cavity 21 for smooth water intake. In this solution, the second trigger structure 271 has three positions: a first non-trigger position, a trigger position, and a second non-trigger position. Depending on the usage scenario, the second trigger structure 271 can switch between these three positions for convenient use. Furthermore, when the user takes water, the valve core 2261 is closed to prevent water from flowing out of the vent 221 and spilling onto the table or floor, affecting the user experience. It should be understood that the locking and unlocking structure and principle of the locking element 27 in this solution are the same as in the first embodiment and will not be repeated here.

[0318] Of course, the position of the second trigger structure 271 is not limited to the above technical solution. In another embodiment, the second trigger structure 271 may only have two positions: a trigger position and a non-trigger position (not shown in the figure). Specifically, when the second trigger structure 271 is in the non-trigger position, the locking element 27 locks the lid assembly 22, and the valve core 2261 is in the closed position. At this time, the user cannot take water, and the vent 221 is closed, so the detachable kettle 2 is in a completely sealed state. The detachable kettle 2 can be placed at any angle without easily leaking water, thus meeting the storage needs of different scenarios. When the second trigger structure 271 is in the trigger position, the locking element 27 releases the lock on the lid assembly 22, and the valve core 2261 is in the open position.

[0319] The following text uses the example of "the second trigger structure 271 having a first non-trigger position, a trigger position, and a second non-trigger position" to illustrate the specific situation.

[0320] In one embodiment, the detachable kettle 2 is mounted on the main unit 1 along a first direction, and a first non-trigger position, a trigger position, and a second non-trigger position are sequentially distributed along a second direction; wherein the first direction is opposite to the second direction. In a specific embodiment, the first direction is the direction from front to back along the main unit 1, and the second direction is the direction from back to front along the main unit 1. For ease of explanation, the following description will use "the first direction is the direction from front to back along the main unit 1, and the second direction is the direction from back to front along the main unit 1" as an example.

[0321] Furthermore, such as Figure 2 , Figures 15 to 18 As shown, during the installation of the detachable kettle 2 onto the main unit 1, the locking element 27 moves under the influence of the first trigger structure 111 on the main unit 1, causing the second trigger structure 271 to move from the first non-trigger position to the trigger position. Specifically, as... Figure 2 , Figure 15 and Figure 16 As shown, during the installation of the detachable kettle 2 onto the main unit 1, the locking element 27 moves relative to the main unit 1 in the first direction (from front to back) until the locking element 27 contacts the first trigger structure 111. As the locking element 27 continues to move in the first direction, the first trigger structure 111 remains stationary. Thus, the locking element 27 presses the first trigger structure 111 in the first direction. In this way, the first trigger structure 111 will exert a reaction force on the locking element 27 in the second direction (from back to front) to prevent the locking element 27 from continuing to move in the first direction. As the detachable kettle 2 continues to move in the first direction, the locking element 27 will move relative to the vent 221 in the second direction, thereby causing the second trigger structure 271 to move from the first non-trigger position to the trigger position.

[0322] Furthermore, such as Figure 15 As shown, the second trigger structure 271 is a protruding structure, and the second trigger structure 271 includes a second guide slope 2711, a second abutment surface 2712 and a third guide slope 2713 distributed sequentially along the first direction (the direction from front to back along the host 1).

[0323] like Figures 15 to 17 As shown, since the first non-trigger position, the trigger position, and the second non-trigger position are sequentially distributed along the second direction (along the back-to-forward direction of host 1), therefore, as Figure 15 and Figure 16As shown, when the second trigger structure 271 moves from the first non-trigger position to the trigger position (i.e., the second trigger structure 271 moves along the second direction), the second guide ramp 2711 moves to press against the valve core 2261. Under the pushing force applied by the second guide ramp 2711, the valve core 2261 moves along the second guide ramp 2711, thereby causing the valve core 2261 to move toward the open position, as shown. Figure 16 As shown, when the valve core 2261 moves to the open position, the second abutment surface 2712 presses against the valve core 2261 to keep the valve core 2261 in the open position. At this time, the second trigger structure 271 is in the trigger position.

[0324] like Figure 16 and Figure 17 As shown, when the second triggering structure 271 moves from the triggering position to the second non-triggering position (i.e., the second triggering structure 271 moves along the second direction), the second triggering structure 271 releases its pressure on the valve core 2261, the valve core 2261 disengages from the second abutment surface 2712, and under the rebound force of the second elastic element 2262, the valve core 2261 returns to the closed position, and the vent 221 is closed. At this time, as... Figure 17 As shown, the second trigger structure 271 is in the second non-trigger position, and the locking element 27 releases the lock on the lid assembly 22, allowing the user to take water.

[0325] like Figure 16 and Figure 17 As shown, when the second trigger structure 271 moves from the second non-trigger position to the trigger position (i.e., the second trigger structure 271 moves along the first direction), the third guide slope 2713 moves to press against the valve core 2261. Under the pushing force applied by the third guide slope 2713, the valve core 2261 moves along the third guide slope 2713, thereby moving the valve core 2261 to the open position. The second abutment surface 2712 presses against the valve core 2261 again to keep the valve core 2261 in the open position. At the same time, the locking element 27 relocks the lid assembly 22, and the user cannot take water. At this time, the second trigger structure 271 is in the trigger position.

[0326] Furthermore, such as Figure 15 As shown, the longitudinal section of the second trigger structure 271 is roughly V-shaped, and the second trigger structure 271 gradually narrows in the direction toward the pot cavity 21. The second guide slope 2711 and the third guide slope 2713 have opposite inclination directions, and the second abutment surface 2712 is a plane so as to stably press the valve core 2261 against the open position.

[0327] Furthermore, the first trigger structure 111 can be an arbitrarily formed protrusion structure, or it can be the same as the structure in the first embodiment. Thus, the host 1 can be applied to the detachable kettle 2 in the first embodiment, or it can be applied to the detachable kettle 2 in the second embodiment. Specifically, as shown... Figure 2 As shown, the first trigger structure 111 is provided with a first guide slope 1111, such as Figure 2 , Figure 15 and Figure 16 As shown, during the process of the detachable kettle 2 being installed on the main unit 1 along the first direction (from front to back along the main unit 1), the detachable kettle 2 moves until the locking element 27 contacts the first guide ramp 1111. Then, as the detachable kettle 2 continues to move along the first direction, the first guide ramp 1111 pushes the locking element 27 along the second direction, thereby pushing the second trigger structure 271 to move along the second direction, so that the valve core 2261 moves toward the open position. That is to say, in this scheme, the first guide ramp 1111 is used to indirectly drive the valve core 2261 to move toward the open position. The role of the first guide ramp 1111 is to provide a pushing force to the locking element 27, but it does not have the function of guiding the movement direction of the locking element 27.

[0328] In one implementation, such as Figure 15 and Figure 18 As shown, the locking element 27 is movably installed on the movable cover 223. The first cover 2221 is provided with a fourth through hole 22215, and the second cover 2222 is also provided with a fifth through hole 22225. The fourth through hole 22215 and the fifth through hole 22225 cooperate to form a vent 221. Specifically, if the water outlet 2224 of the fixed cover 222 is matched with the third through hole 2231 of the movable cover 223 to form a vent 221, the locking element 27 needs to be placed above the movable cover 223, which increases the height of the detachable kettle 2 and makes the corresponding assembly structure of the locking element 27 more complicated. In this solution, the locking element 27 is directly installed on the movable cover 223, and the fixed cover 222 is provided with a water outlet 2224 (formed by the matching of the first through hole 22211 and the second through hole 22223) and a vent 221 (formed by the matching of the fourth through hole 22215 and the fifth through hole 22225), which facilitates the matching of the second triggering structure 271 with the valve core 2261 provided in the vent 221, and the locking element 27 is easy to assemble.

[0329] Furthermore, such as Figure 15 and Figure 18As shown, when the movable cover 223 is in the closed position, the movable cover 223 is embedded in the second cover 2222 and closes the water outlet 2224. The vent 221 is located on the side of the water outlet 2224 away from the spout 22222. In this way, when the user pours water, the water flowing out of the water outlet 2224 will not or will not easily come into contact with the valve core 2261, thus avoiding the valve core 2261 from contaminating the drinking water.

[0330] In one embodiment, since the second trigger structure 271 has three positions—a first non-trigger position, a trigger position, and a second non-trigger position—the locking element 27 also has three positions. To ensure that the locking element 27 can stably perform its function, the locking element 27 needs to remain stable in the corresponding position. In this solution, for example... Figure 18 As shown, the movable cover 223 is provided with a first limiting structure 22341, a second limiting structure 22342, and a third limiting structure 22343 arranged sequentially. Figure 15 and Figure 18 As shown, when the second trigger structure 271 is in the first non-triggering position, the first limiting structure 22341 restricts the second trigger structure 271 from leaving the first non-triggering position to ensure that the second trigger structure 271 can be stably in the first non-triggering position. When the force on the second trigger structure 271 is greater than a preset value, the second trigger structure 271 is released from the restriction of the first limiting structure 22341. Figure 16 and Figure 18 As shown, when the second trigger structure 271 is in the trigger position, the second limiting structure 22342 restricts the second trigger structure 271 from leaving the trigger position to ensure that the second trigger structure 271 can be stably in the trigger position. When the force on the second trigger structure 271 is greater than a preset value, the second trigger structure 271 is released from the restriction of the second limiting structure 22342. Figure 17 and Figure 18 As shown, when the second trigger structure 271 is in the second non-trigger position, the third limiting structure 22343 restricts the second trigger structure 271 from leaving the second non-trigger position to ensure that the second trigger structure 271 can be stably in the second non-trigger position. When the force on the second trigger structure 271 is greater than a preset value, the second trigger structure 271 is released from the restriction of the third limiting structure 22343. It should be understood that if the locking element 27 has two positions, the movable cover 223 is provided with two limiting structures so that the locking element 27 can be stably in the corresponding position. That is, the number of positions of the locking element 27 is the same as the number of limiting structures provided on the movable cover 223.

[0331] Furthermore, such as Figure 18 As shown, the first limiting structure 22341, the second limiting structure 22342 and the third limiting structure 22343 are all limiting groove structures, which are simple in structure and easy to process.

[0332] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of the present invention that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of the present invention and do not limit the scope of protection of this patent.
