The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a heating tank shown includes a tank body 100, a top cover assembly 200 and a one-way valve 400. The tank body 100 is provided with an assembly port 11 for assembling the top cover assembly 200. The top cover assembly 200 is inserted and covered at the assembly port 11. A first sealing structure 01 and a second sealing structure 02 for sealing are arranged between the opposite surfaces of the tank body 100 and the top cover assembly 200, and a sealed cavity 03 is formed between the first sealing structure 01 and the second sealing structure 02. In order to be able to suck the inside of the sealed cavity 03 into a vacuum state, a channel 212 connected to the sealed cavity 03 is provided inside the top cover assembly 200. The one-way valve 400 is arranged on the top cover assembly 200 and is connected to the channel 212. Therefore, the inside of the sealed cavity 03 can be sucked into a vacuum state through the one-way valve 400, and the sealing performance of the first sealing structure 01 and the second sealing structure 02 can be effectively improved under the action of the vacuum negative pressure.

[0030] In summary, the first sealing structure 01 and the second sealing structure 02 are arranged between the tank body 100 and the top cover assembly 200 to achieve a double sealing effect, so that the sealing of the heating tank is improved. By sucking the inside of the sealed cavity 03 into a vacuum state through the one-way valve 400, the sealing of the first sealing structure 01 and the second sealing structure 02 can be further improved under the action of the vacuum negative pressure. And when the sealed cavity 03 is vacuum-sucked by the one-way valve 400, the airtightness of the first sealing structure 01 and the second sealing structure 02 can be indirectly reflected by observing whether there is air leakage during the suction process, thereby ensuring that after the top cover assembly 200 is assembled with the tank body 100, the first sealing structure 01 and the second sealing structure 02 can simultaneously play a good sealing effect.

[0031] The following will introduce the technical details of each component one by one.

[0032] In some embodiments, Figure 2 , Figure 3 As shown, the heating tank further includes a sealing ring 300, which can be a rubber ring. The sealing ring 300 is arranged between the top cover assembly 200 and the tank body 100. The top cover assembly 200 and the tank body 100 are both against the sealing ring 300 to form a first sealing structure 01. The first sealing structure 01 seals the connection between the top cover assembly 200 and the tank body 100 through the sealing ring 300. The sealing method of the sealing ring 300 is relatively simple in structure, which can reduce the cost and operation difficulty in the production process.

[0033] In some embodiments, Figure 2 , Figure 3As shown, the mating surfaces of the tank body 100 and the top cover assembly 200 are surrounded by a ring protrusion 12, which is sealed against the top cover assembly 200 to form a second sealing structure 02. The sealing against the ring protrusion 12 can facilitate the pre-positioning of the top cover assembly 200 during the assembly process.

[0034] In actual applications, the ring protrusion 12 can well abut against the outer periphery of the top cover assembly 200, thereby playing a role of clamping and fixing, so that during the production and processing process, the top cover assembly 200 can be pre-fixed in an appropriate position first, and then further fixed by screws or other means to complete the production process.

[0035] In some embodiments, Figure 2 , Figure 3 As shown, a sealing groove 221 is provided at the abutment point between the top cover assembly 200 and the sealing ring 300. The sealing groove 221 can, on the one hand, position the sealing ring to prevent the sealing ring 300 from sliding and shifting during the assembly of the top cover assembly 200, and on the other hand, increase the contact surface area between the sealing ring 300 and the top cover assembly 200 to improve the sealing between the sealing ring 300 and the top cover assembly 200.

[0036] In actual applications, since the sealing ring 300 can be a rubber ring, the texture of the rubber ring is relatively soft and can be easily deformed under extrusion. Therefore, when the top cover assembly 200 is interpolated and assembled to the assembly port 11 of the tank body 100, the sealing ring 300 is squeezed and rubbed, which can easily cause the position of the sealing ring 300 to shift. By setting a sealing groove 221 at a predetermined position of the top cover assembly 200 and then inserting the sealing ring 300 into the sealing groove 221, the sealing ring 300 can be clamped at the predetermined position of the top cover assembly 200, so that the sealing ring 300 will not shift during the assembly process of the top cover assembly 200 and affect the sealing effect of the sealing ring 300, thereby ensuring that the sealing ring 300 can be accurately set at the predetermined position to form a first sealing structure 01 with good sealing effect.

[0037] In some embodiments, Figure 2 , Figure 3As shown, the top cover assembly 200 includes a cover portion 21 and an insertion portion 22, the insertion portion 22 is inserted into the assembly port 11 and connected to the cover portion 21, and an annular groove 223 is provided on the insertion portion 22, and the annular protrusion 12 is abutted against the annular groove 223. The annular groove 223 can enhance the engagement strength of the structure between the annular protrusion 12 and the top cover assembly 200, and can also play a positioning role. In practical applications, after the insertion portion 22 is inserted into the assembly port 11, the cover portion 21 can cover the assembly port 11, resulting in the operator being unable to directly observe the specific position of the annular protrusion 12 abutting against the top cover assembly 200. By providing the annular groove 223 on the top cover assembly 200, it can be determined whether the top cover assembly 200 is assembled to the appropriate position by the engagement of the annular protrusion 12 with the annular groove 223 during the assembly process, which can be beneficial to improve and ensure the sealing of the second sealing structure 02 formed between the annular protrusion 12 and the top cover assembly 200.

[0038] In some embodiments, Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the top cover assembly 200 further includes a flexible ring 23, which is disposed around the insertion portion 22 and abuts against the ring protrusion 12. The flexible ring 23 can be made of elastic materials such as rubber silicone.

[0039] It can be understood that the annular protrusion 12 can produce a better sealing effect after abutting against the flexible ring 23 made of flexible material, and the sealing performance of the second sealing structure 02 can be further improved.

[0040] In some embodiments, one of the flexible ring 23 and the insertion portion 22 is provided with a snap-fit ​​protrusion 222, and the other of the flexible ring 23 and the insertion portion 22 is provided with a snap-fit ​​groove 231. The snap-fit ​​protrusion 222 can be welded to the insertion portion 22 or molded as a whole with the insertion portion 22. The snap-fit ​​groove 231 is used to snap-fit ​​with the snap-fit ​​protrusion 222 to fix the flexible ring 23 to the insertion portion 22.

[0041] like Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the above-mentioned engaging protrusion 222 is arranged on the insertion part 22, and the engaging notch 231 is provided on the flexible ring 23. Of course, the engaging protrusion 222 can also be arranged on the flexible ring 23, and the engaging notch 231 is provided on the insertion part 22. After the engaging protrusion 222 is engaged with the engaging notch 231, the flexible ring 23 can be well prevented from being deflected during the insertion process of the insertion part 22, which is conducive to ensuring the sealing effect of the second sealing structure 02.

[0042] In some embodiments, Figure 2 , Figure 4 As shown, the heating tank also includes an air pressure monitoring device 500, which is connected to the top cover assembly 200 to monitor the air pressure inside the sealed cavity 03; the air pressure monitoring device 500 includes an air pressure sensor (not shown in the figure) and a display (not shown in the figure), the air pressure sensor is electrically connected to the display and is arranged inside the channel 212, the air pressure sensor converts the air pressure data inside the channel 212 into an electrical signal and transmits it to the display for display, so as to facilitate user observation.

[0043] In actual application, the display is mounted on the outer side of the top cover assembly 200 for viewing by the user, and the air pressure sensor (not shown in the figure) is arranged inside the channel 212 to convert the air pressure data inside the channel 212 into an electrical signal and transmit it to the display for display. Through the above design, the air pressure value inside the channel 212 can indirectly and intuitively reflect the sealing performance of the first sealing structure 01 and the second sealing structure 02. Specifically, if the first sealing structure 01 and the second sealing structure 02 have good sealing performance, the inside of the sealed cavity 03 will always maintain a vacuum state, and the corresponding air pressure monitoring device 500 will display in real time that the air pressure inside the sealed cavity 03 has always maintained a vacuum state. If the first sealing structure 01 and the second sealing structure 02 leak, the air pressure inside the sealed cavity 03 will gradually increase, and accordingly, the air pressure monitoring device 500 will display the air pressure changes inside the sealed cavity 03 in real time. The user can know whether the airtightness of the first sealing structure 01 and the second sealing structure 02 is good by observing the display data of the air pressure monitoring device 500, which can facilitate the user to know the leakage of the heating tank in time before the heating tank leaks and take countermeasures.

[0044] In some embodiments, Figure 2 , Figure 4 As shown, a pressure chamber 211 is provided inside the top cover assembly 200, and the pressure chamber 211 is connected to the one-way valve 400 and the channel 212, and the pressure sensor is arranged inside the pressure chamber 211. The pressure chamber 211 can provide a larger space for assembling the pressure sensor, so that the pressure sensor can more fully sense the pressure change inside the pressure chamber 211. The channel 212 connects the pressure chamber 211 with the sealed cavity 03, so that the pressure inside the pressure chamber 211 is the same as the pressure inside the sealed cavity 03. In summary, the pressure chamber 211 is conducive to improving the sensing accuracy of the pressure sensor.

[0045] The present application also provides a water purifier, which includes the above-mentioned heating tank inside. Through the heating tank, the real-time sealing condition of the heating tank can be visually observed.
