[0131] In this utility model, "front," "rear," "left," "right," "up," and "down" all refer to... Figure 6 and Figure 8 The markings in the text shall prevail.

[0132] The following is based on Figures 1 to 17This utility model describes the water purification equipment in detail.

[0133] In this embodiment, such as Figure 1 , Figure 6 and Figure 8 As shown, the water purification device 100 includes a main unit 1 and a detachable kettle 2. The detachable kettle 2 includes a lid assembly 22 and a kettle body 23, which together form a kettle cavity 21. The kettle body 23 is provided with a kettle body inlet 234, which is used to connect to the water circuit of the main unit 1 of the water purification device 100. When the detachable kettle 2 is installed on the main unit 1, if the detachable kettle 2 needs to be replenished with purified water, the main unit 1 provides purified water to the detachable kettle 2 through the kettle body inlet 234. When the detachable kettle 2 is removed from the main unit 1, the kettle body inlet 234 is in a closed state to prevent water in the detachable kettle 2 from leaking from the kettle body inlet 234.

[0134] like Figure 2 and Figure 3 As shown, the kettle lid assembly 22 includes a fixed lid body 222 and a movable lid body 223. The fixed lid body 222 has a water outlet 2224 and an air inlet channel 2225. The fixed lid body 222 is connected to the kettle body 23, and the movable lid body 223 is movably connected to the fixed lid body 222. When the detachable kettle 2 is detached from the main unit 1 and the movable lid body 223 is in the closed position, the movable lid body 223 closes the water outlet 2224 and the air inlet channel 2225, so that the detachable kettle 2 can be in a sealed state. That is, when the movable lid body 223 is in the closed position, the detachable kettle 2 is in a sealed state. If the movable lid body 223 is removed from the closed position, the detachable kettle 2 is in a non-sealed state. When the detachable kettle 2 is detached from the main unit 1 and the movable lid 223 is in the open position, the movable lid 223 opens the water outlet 2224 and the air inlet channel 2225. In this way, the user can pour the water in the kettle cavity 21 out of the water outlet 2224 by tilting the detachable kettle 2. During the process of water flowing out of the water outlet 2224, outside air can enter the kettle cavity 21 through the air inlet channel 2225 so that the air pressure in the kettle cavity 21 is balanced with the outside air pressure.

[0135] In the above technical solution, the structure of the kettle lid assembly 22 is improved by simultaneously providing a water outlet 2224 and an air inlet channel 2225 on the fixed lid 222. This allows the kettle cavity 21 to achieve air pressure balance through the air inlet channel 2225 during water flow from the water outlet 2224, ensuring smooth water flow and preventing prolonged water flow time and noise from the detachable kettle 2, which would negatively impact user experience. Furthermore, when the detachable kettle 2 is detached from the main unit 1 and the movable lid 223 is in the closed position, the movable lid 223 simultaneously closes both the water outlet 2224 and the air inlet channel 2225, ensuring the detachable kettle 2 is sealed and preventing external contaminants from entering the kettle cavity, thus ensuring safe drinking water.

[0136] It should be understood that the air intake channel 2225 in this solution is used to introduce air into the kettle cavity 21 during the process of water flowing out of the water outlet 2224, so as to maintain the air pressure balance in the kettle cavity 21 during the process of pouring water from the detachable kettle 2. In other words, the air flow direction in the air intake channel 2225 is from the outside of the detachable kettle 2 to the kettle cavity 21, with the purpose of improving the smoothness of water flowing out of the water outlet 2224.

[0137] In one embodiment, the detachable kettle 2 is a cold water kettle or a water purifier kettle, which does not have a heating function, and there is no steam in the kettle cavity 21. No pressure relief is required during the pouring process.

[0138] In one implementation, such as Figure 2 and Figure 3 As shown, the air inlet 22251 of the air inlet channel 2225 is connected to the water outlet 2224. Specifically, the air inlet channel 2225 includes an air inlet 22251, a venting chamber 22253 and an air outlet 22252 connected in sequence. The air outlet 22252 is connected to the kettle cavity 21. When air is introduced into the air inlet channel 2225, outside air enters the kettle cavity 21 in sequence through the air inlet 22251, the venting chamber 22253 and the air outlet 22252. The air inlet 22251 is configured to communicate with the water outlet 2224. That is, the air inlet 22251 is opened on the hole wall of the water outlet 2224. During the air intake process of the air intake channel 2225, the outside air enters the air inlet 22251 through the water outlet 2224, and then enters the kettle cavity 21 through the venting chamber 22253 and the air outlet 22252. In this solution, the opening position of the air inlet 22251 is optimized. The position of the air inlet 22251 is inconspicuous, which helps to improve the aesthetic appearance of the fixed cover 222. In addition, when the detachable kettle 2 is being poured, the water flowing out of the outlet 2224 does not flow through the air inlet 22251, so as to avoid water flowing through the air inlet 22251 into the air intake channel 2225, which would cause water to remain in the air intake channel 2225 or cause water to flow back into the kettle cavity 21 through the air intake channel 2225, thus affecting the pouring of water from the detachable kettle 2.

[0139] Furthermore, such as Figure 3 As shown, the air inlet 22251 faces upwards and is positioned near the outer end port 22241 of the water outlet 2224. The water outlet 2224 includes an inner end port 22242 and an outer end port 22241 spaced apart along the water flow direction. When water flows out of the water outlet 2224, the water in the kettle cavity 21 first enters the water outlet 2224 through the inner end port 22242, and then the water in the water outlet 2224 is poured out through the outer end port 22241. In this design, by limiting the position of the air inlet 22251, it is ensured that the water flowing out of the water outlet 2224 does not flow through the air inlet 22251 during the pouring process of the detachable kettle 2.

[0140] In one implementation, such as Figures 2 to 4 As shown, the fixed lid 222 includes a spout 22222, through which water from the outlet 2224 is poured out. An air inlet 22251 is located on the side of the outlet 2224 away from the spout 22222. Thus, when the detachable kettle 2 is poured, the water from the outlet 2224 flows towards the spout 22222. Because the air inlet 22251 is located on the side of the outlet 2224 away from the spout 22222, the water from the outlet 2224 will not flow through the air inlet 22251, thus preventing water from flowing into the air intake channel 2225.

[0141] Furthermore, such as Figure 4 As shown, the air inlet 22251 has an axisymmetric structure and a first axis of symmetry, the water outlet 2224 has an axisymmetric structure and a second axis of symmetry, and the spout 22222 has an axisymmetric structure and a third axis of symmetry. The first, second, and third axes of symmetry coincide, and, as shown... Figure 3 and Figure 4 As shown, the air inlet 22251, water outlet 2224 and spout 22222 are staggered along the first axis of symmetry. The "staggered distribution" can be completely staggered or partially staggered, so as to maximize the distance between the air inlet 22251 and the spout 22222, thereby further ensuring that the water flowing out of the water outlet 2224 will not flow through the air inlet 22251 when the detachable kettle 2 is being poured.

[0142] In one implementation, such as Figure 3 As shown, the position of the air outlet 22252 is configured such that when the detachable kettle 2 is poured, the water in the kettle cavity 21 will not come into contact with the air outlet 22252, so as to ensure smooth air intake of the air intake channel 2225.

[0143] In one implementation, such as Figure 3As shown, the air outlet 22252 of the air inlet channel 2225 is located on the side of the water outlet 2224 away from the spout 22222, and the air outlet 22252 is set away from the water outlet 2224. Specifically, when the detachable kettle 2 pours water, the water surface in the kettle cavity 21 remains parallel to the horizontal plane because the detachable kettle 2 is tilted. Therefore, the water surface in the kettle cavity 21 will eventually contact the water outlet 2224 to achieve pouring. This solution limits the position of the air outlet 22252 to avoid the water in the kettle cavity 21 from contacting the air outlet 22252 during the pouring process of the detachable kettle 2. In fact, water may enter the air inlet channel 2225 through the air outlet 22252, thereby hindering the air intake process of the air inlet channel 2225. That is, by optimizing the setting of the air outlet 22252, the smooth air intake of the air inlet channel 2225 is ensured.

[0144] In one implementation, such as Figure 2 and Figure 3 As shown, the inner wall of the movable cover 223 is provided with a first protrusion 2232, and a third sealing element 225 is provided on the first protrusion 2232. Figure 2 As shown, when the movable cover 223 is in the closed position, the third seal 225 presses against the outer end port 22241 of the water outlet 2224; the third seal 225 cooperates with the first protrusion 2232 to close the outer end port 22241 of the water outlet 2224. Since the air inlet 22251 is connected to the water outlet 2224, the third seal 225 and the first protrusion 2232 can also simultaneously close the air inlet 22251 of the air inlet channel 2225. In this design, the third seal 225 cooperates with the first protrusion 2232 to simultaneously close the water outlet 2224 and the air inlet channel 2225. Compared to a design where the air inlet and water outlet are not connected, this design requires two seals to seal the air inlet and water outlet respectively, and two protrusions to install the two seals separately. This design reduces the number of seals and protrusions on the movable cover, simplifying the structure of the lid assembly 22 and reducing manufacturing costs. Furthermore, the third seal 225 is fitted onto the first protrusion 2232, making installation convenient. Since the first protrusion 2232 is located on the movable cover 223, if the sealing performance of the third seal 225 fails, the movable cover 223 can be rotated to the open position to replace the third seal 225.

[0145] In one implementation, such as Figure 2 and Figure 12As 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 pot body 23, and the second lid 2222 is fixed to the first lid 2221. The fixed lid 222 is designed as a split structure to simplify the structure of a single lid, facilitate processing, and reduce the defect rate during processing. The first lid 2221 and the second lid 2222 together form a venting cavity 22253. The first lid 2221 has an air outlet 22252, and the second lid 2222 has an air inlet 22251. The air inlet 22251, the venting cavity 22253, and the air outlet 22252 are connected in sequence to form an air intake channel 2225. In this design, the first lid 2221 and the second lid 2222 cooperate to form an air intake channel 2225. Compared with the design where the air intake channel 2225 is set on a single lid, this design is easier to process.

[0146] Furthermore, such as 3 and Figure 5 As shown, the first cover 2221 is provided with a fourth groove 22217, and the inner wall of the second cover 2222 fits with the fourth groove 22217 to form a ventilation cavity 22253. The fourth groove 22217 is easy to process and requires little structural modification to the inner wall of the second cover 2222.

[0147] Furthermore, such as Figure 2 , Figure 3 and Figure 12 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.

[0148] Furthermore, such as Figures 3 to 5 , Figure 12As shown, the first through hole 22211 and the air outlet 22252 are both located in the fourth groove 22217. The second cover 2222 is provided with a second annular post 22227 on the side facing the first cover 2221. The inner wall of the second annular post 22227 at least constitutes part of the hole wall of the second through hole 22223. The second annular post 22227 extends into the fourth groove 22217. The second annular post 22227 is used to separate the venting chamber 22253 from the water outlet 2224 to prevent the water outlet 2224 from being directly connected to the venting chamber 22253. In one specific embodiment, the second annular column 22227 abuts against the groove wall of the fourth groove 22217, so that the first through hole 22211 and the second through hole 22223 are connected in sequence to form a water outlet 2224. At the same time, the first cover 2221 and the second cover 2222 together form a venting cavity 22253.

[0149] Furthermore, such as Figure 3 , Figure 4 and Figure 12 As shown, the second annular column 22227 includes a first protruding rib 222271 and a second protruding rib 222272 connected end to end; the second protruding rib 222272 cooperates with the inner wall of the outer end port 22241 of the outlet 2224 to form an air inlet 22251. In this design, the second annular column 22227 has a simple structure, and the cooperation between the second annular column 22227 and the outlet 2224 is simple and ingenious, forming the air inlet 22251 while allowing the air inlet 22251 to communicate with the outlet 2224.

[0150] Furthermore, such as Figure 4 and Figure 12 As shown, both the first rib 222271 and the second rib 222272 are arc-shaped. This makes their surfaces smooth, reducing air intake noise at the air inlet 22251 and water outlet noise at the water outlet 2224. Furthermore, the second rib 222272 is located within the circumference of the first rib 222271, allowing the air inlet 22251 to communicate with the water outlet 2224. Additionally, the structure of the second cover 2222 is simple to modify, reducing modification costs.

[0151] In one implementation, such as Figure 5 and Figure 12As shown, the cross-section of the first cover 2221 is circular. The fourth groove 22217 intersects the central axis of the first cover 2221 and extends radially along the first cover 2221. The first through hole 22211 and the air outlet 22252 are located at the two ends of the fourth groove 22217, respectively, to maximize the distance between the air outlet 22252 and the water outlet 2224, so as to ensure that the water in the kettle cavity 21 does not easily or will not come into contact with the air outlet 22252 during the pouring process of the detachable kettle 2, thereby ensuring smooth air intake of the air intake channel 2225.

[0152] In one implementation, such as Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, the detachable kettle 2 also includes a vent 221, which communicates with the kettle cavity 21. When the detachable kettle 2 is installed on the main unit 1, the vent 221 is in the open state. When the detachable kettle 2 needs to be refilled, clean water from 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. That is, the open vent 221 allows the main unit 1 to provide clean water to the detachable kettle 2 through the kettle body water inlet 234. When the detachable kettle 2 is removed from the main unit 1, the vent 221 switches to the closed state to prevent water from leaking from the kettle cavity 21 through the vent 221. Of course, if the water purification equipment 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 inlet 234, that is, the kettle body water inlet 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.

[0153] Through the above technical solution, by adding a vent 221 to the detachable kettle 2, when the detachable kettle 2 is installed on the main unit 1, the vent 221 is in the open state, so that the kettle cavity 21 is connected to the atmosphere, thereby ensuring that the kettle cavity 21 can smoothly receive water to the preset high water level (increasing water storage capacity) or supply water to the preset low water level (facilitating the use up of water). Furthermore, when the detachable kettle 2 is removed from the main unit 1, the vent 221 is in the closed state, which ensures that water will not spill out of the kettle cavity through the vent 221.

[0154] In one implementation, such as Figure 2 and Figure 9As 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.

[0155] In one implementation, such as Figure 2 As shown, the vent 221 is located on the lid assembly 22, without requiring any changes to the structure of the kettle body 23.

[0156] In one implementation, such as Figure 2 As shown, the first cover 2221, the second cover 2222, and the movable cover 223 are arranged sequentially in a direction away from the pot cavity 21.

[0157] Furthermore, such as Figure 3 , Figure 9 , Figure 11 and Figure 12 As 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.

[0158] Furthermore, such as Figure 3 and Figure 9 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.

[0159] In one implementation, such as Figure 2 and Figure 3 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.

[0160] Furthermore, such as Figure 2 and Figure 3As shown, when a user needs to pour water, they remove the detachable kettle 2, rotate the movable lid 223 to the open position, opening the spout 2224. By tilting the detachable kettle 2, the water in the kettle cavity 21 flows sequentially through the spout 2224 and the spout 22222 before entering the user's cup, as the spout 22222 is connected to the spout 22222. 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 cleanliness and ensuring safe drinking water.

[0161] Furthermore, such as Figure 2 and Figure 4 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 both sides of the mounting portion 22221. Figure 3 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 2 As shown, when the external force is removed, the first elastic element 224 rebounds to drive the movable cover 223 back to the closed position. Furthermore, the first elastic element 224 applies a supporting force to the movable cover 223, so that the end of the movable cover 223 opposite to the spout 22222 can be stably covered on the spout 22222. That is, it is beneficial to keep the movable cover 223 in the closed position and prevent the movable cover 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.

[0162] Furthermore, such as Figure 2 As shown, the first elastic element 224 is a spring, which has a simple structure.

[0163] In one implementation, such as Figure 2 , Figure 3 and Figure 12As shown, the movable cover 223 has a third through hole 2231. When the movable cover 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 cover 222, reducing the risk of leakage, reducing the impact of openings on the structural strength of the fixed cover 222, simplifying the structure of the kettle lid assembly 22, facilitating processing, and reducing processing costs. Of course, the configuration of the vent 221 is not limited to the above solution. The vent 221 can also be directly set on the fixed cover 222 without opening a hole in the movable cover 223.

[0164] In one implementation, such as Figure 2 and Figure 3 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.

[0165] Furthermore, such as Figure 2 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 removable kettle 2 can be in a sealed state.

[0166] Furthermore, such as Figure 2 and Figure 3 As shown, the first protrusion 2232 of the movable cover 223 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, by providing the third sealing element 225, it is used to seal the water outlet 2224 on the one hand, and on the other hand, it is used to seal the connection between the water outlet 2224 and the third through hole 2231, ensuring the airtightness of the connection between the two.

[0167] In one implementation, such as Figure 4 and Figure 6 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.

[0168] In one implementation, such as Figure 3 , Figure 11 and Figure 12 As 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, this 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.

[0169] Furthermore, such as Figure 3 and Figure 11 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 11 and Figure 12 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.

[0170] Furthermore, such as Figure 3 and Figure 11 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 11 and Figure 12As 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.

[0171] Furthermore, such as Figure 11 and Figure 12 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.

[0172] In one implementation, such as Figure 3 and Figure 12 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.

[0173] In one implementation, such as Figure 2 As shown, the detachable kettle 2 also includes a valve assembly 226, which includes a valve core 2261 and a second elastic element 2262. The valve core 2261 is movably installed in the vent 221, and one end of the second elastic element 2262 abuts against the valve core 2261, while the other end abuts against an abutment platform within the vent 221. Figure 9 As shown, 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, in order 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 14 As 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 can be in a sealed state. In one specific embodiment, as... Figure 2 , Figure 9 and Figure 14As shown, the vent 221 is located on the top wall of the detachable kettle 2. The valve core 2261 moves along the vertical direction of the main unit 1 to switch between the open and closed positions. Of course, the movement direction of the valve core 2261 is not limited to the vertical direction of 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 the open and closed positions 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.

[0174] Furthermore, such as Figure 2 , Figure 9 and Figure 14 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 through this vent gap. 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 the vent 221, thus ensuring the removable kettle 2 is sealed.

[0175] 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.

[0176] Furthermore, such as Figures 7 to 9 , Figure 14 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.

[0177] Furthermore, such as Figure 7 As shown, the host 1 includes a housing 11, and a first trigger structure 111 is disposed on the housing 11 for easy processing.

[0178] In one implementation, such as Figure 14 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 9As shown, during the movement of the valve core 2261, the valve core 2261 compresses the second elastic element 2262. For example... Figure 14 As 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.

[0179] Furthermore, such as Figure 7 and Figure 14 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 9 and Figure 14 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 9 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.

[0180] In one implementation, such as Figure 6As 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.

[0181] 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.

[0182] In one implementation, such as Figure 9 and Figure 14 As shown, the valve assembly 226 is mounted on the lid assembly 22 of the detachable kettle 2, as... Figure 2 and Figure 6 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 14 As 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 6 and Figure 13 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.

[0183] 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 6 and Figure 13 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 follows. Figure 13 and Figure 14As 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.

[0184] Furthermore, such as Figure 2 , Figure 9 and Figure 12 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 13 and Figure 14 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.

[0185] In one implementation, such as Figure 2 , Figure 9 and Figure 12 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.

[0186] Furthermore, such as Figure 2 , Figure 9 and Figure 12As shown, the lid assembly 22 includes a fixed lid 222 and a movable lid 223, with a locking element 27 movably mounted on the movable lid 223. When the locking element 27 is in the locked position, it is restricted by the fixed lid 222 to prevent the movable lid 223 from moving to the open position. That is, the locking element 27 enables the movable lid 223 to be stably kept in the closed position. In this way, the movable lid 223 can stably close the water outlet 2224 and the air inlet 2225, and the water outlet 2224 is in a tightly sealed state, preventing leakage from the detachable kettle 2. The detachable kettle 2 can be placed at any angle, for example, horizontally in the refrigerator, and then consumed after refrigeration, meeting the storage needs of different scenarios and enriching the functions of the detachable kettle 2. The detachable kettle 2 has diversified storage methods. In addition to storing purified water, the detachable kettle 2 can also be used to store other liquid foods (such as alcoholic beverages). It should be understood that when the locking element 27 is in the open position, the water outlet 2224 is in a loosely sealed state. That is, when the detachable kettle 2 is placed vertically, the movable cover 223 can cover the water outlet 2224 relatively stably under its own weight. When the detachable kettle 2 is placed at an angle, the movable cover 223 may move to its open position, and the water outlet 2224 will be opened.

[0187] Furthermore, such as Figure 2 and Figure 3 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.

[0188] Furthermore, such as Figure 2 and Figure 3 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 3 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.

[0189] In one implementation, such as Figure 2 and Figure 3As 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 4 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.

[0190] In one implementation, such as Figure 13 As shown, the movable cover 223 is provided with a fourth limiting structure 2235. (As...) Figure 2 and Figure 13 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 3 and Figure 13 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.

[0191] In one implementation, such as Figure 2 and Figure 13 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.

[0192] Furthermore, such as Figure 2 and Figure 13 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.

[0193] Furthermore, such as Figure 2 and Figure 13 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.

[0194] In one implementation, such as Figure 2 and Figure 13 As 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.

[0195] In one implementation, such as Figure 6 and Figure 17 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.

[0196] In one implementation, such as Figure 1 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 8 and Figure 10 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.

[0197] Furthermore, such as Figure 10As 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.

[0198] In one implementation, such as Figure 6 and Figure 10 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.

[0199] Furthermore, such as Figure 10 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.

[0200] In one implementation, such as Figure 6 and Figure 10 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.

[0201] Furthermore, such as Figure 10 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.

[0202] In one implementation, such as Figures 6 to 9 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.

[0203] Furthermore, such as Figure 8 As shown, the convex shell portion 112 is provided with a storage 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.

[0204] In one implementation, such as Figure 15 As 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.

[0205] 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.

[0206] Furthermore, such as Figure 15 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.

[0207] Furthermore, such as Figure 8 and Figure 15 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.

[0208] Furthermore, such as Figure 8 , Figure 10 and Figure 15As 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.

[0209] In one implementation, such as Figure 8 , Figure 10 and Figure 16 As 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.

[0210] 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.

[0211] Furthermore, such as Figure 16 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.

[0212] In one implementation, such as Figure 10 and Figure 16 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.

[0213] Furthermore, such as Figure 10 and Figure 16As 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.

[0214] In one implementation, such as Figure 10 and Figure 16 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.

[0215] In one implementation, such as Figure 6 and Figure 10 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.

[0216] Furthermore, such as Figure 6 and Figure 10As 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.

[0217] In one implementation, such as Figure 6 and Figure 7 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.

[0218] Furthermore, such as Figure 6 and Figure 7 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.

[0219] Furthermore, such as Figure 7 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.

[0220] In one implementation, such as Figure 6 and Figure 7 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.

[0221] Furthermore, such as Figure 6 and Figure 7 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.

[0222] Furthermore, such as Figure 6 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.

[0223] In one implementation, such as Figure 7 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 6 and Figure 7 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.

[0224] In one implementation, such as Figure 6 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.

[0225] In one implementation, such as Figure 6 and Figure 15As 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 12 may be directly connected to the municipal tap water supply through a raw water pipe.

[0226] 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 this utility model that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this utility model and do not limit the scope of protection of this utility model patent.
