[0037] Traditional water dispensers include a water tank device, an instant heating device, and a water outlet device. Among them, the water outlet device has an instant heating connection end for communicating with the instant heating device and a water tank connection end for communicating with the water tank device. In the current market, the instant heating connection end of the water outlet device of traditional water dispensers is usually connected to the instant heating device by inserting a hose (such as a silicone tube). Similarly, the water tank connection end of the water outlet device is also connected to the water tank device by inserting a hose. That is to say, the water outlet device needs to be connected to the water tank device and the instant heating device through at least two hoses. However, due to the limitations of their materials, these hoses are not only prone to deformation, resulting in loosening and falling off of the hoses and leakage of water, but also prone to generating peculiar smells such as plastic smells, making the water conveyed by the hoses have peculiar smells.

[0038] The present invention provides an embodiment of a water dispenser, which can be applied to a water dispenser or other devices with a water supply system. The water dispenser can be a pipeline water dispenser, and the pipeline water dispenser can be a wall-mounted pipeline water dispenser. The water dispenser can reduce the use of hoses, thereby reducing the occurrence of water leakage or peculiar smells caused by hose connections.

[0039] Please refer to Figures 1 to 3 , in an embodiment of the water dispenser of the present invention, the water dispenser includes a housing 100, an instant heating device 200, a water tank device 300, and a water outlet device 400. Among them, the instant heating device 200 is installed in the housing 100, and the instant heating device 200 is provided with an instant heating water outlet end 210; the water tank device 300 is installed in the housing 100, and the water tank device 300 is provided with a water tank water outlet end 310 (as Figure 6 shown); the water outlet device 400 is installed on the housing 100, and the water outlet device 400 includes a water outlet nozzle 410 located outside the housing 100, and an instant heating connection end 420 and a water tank connection end 430 that are communicated with the water outlet nozzle 410 and penetrate into the housing 100 (as Figure 9 and Figure 10 shown); the instant heating connection end 420 is fixedly connected to the instant heating water outlet end 210, and the water tank connection end 430 is fixedly connected to the water tank water outlet end 310.

[0040] Specifically, the housing 100 has an installation cavity; the instant heating device 200 and the water tank device 300 are both installed in the installation cavity of the housing 100, and the water tank device 300 and the instant heating device 200 are arranged vertically; alternatively, the water tank device 300 and the instant heating device 200 are arranged horizontally; or, the water tank device 300 and the instant heating device 200 are arranged longitudinally. In actual production, the arrangement of the water tank device 300 and the instant heating device 200 can be designed accordingly in combination with the position of the water outlet device 400 on the housing 100, and no limitation is set here. In this embodiment, the water tank device 300 and the instant heating device 200 are arranged vertically; wherein, the instant heating device 200 is installed at the bottom of the housing 100; the water tank device 300 is arranged above the instant heating device 200, and the water tank device 300 is fixedly connected to the housing 100.

[0041] The water outlet device 400 is installed at the front end of the housing 100 and is used to output cold water or hot water for use. The water outlet device 400 is internally provided with a valve core assembly 440 for switching the cold water and hot water flow paths. When the user takes cold water, the water in the water tank device 300 is directly output from the water tank water outlet end 310 to the water tank connection end 430 of the water outlet device 400, and then flows out through the water outlet nozzle 410 of the water outlet device 400, so as to output cold water for the user. When the user takes hot water, the water in the instant heating device 200 is directly output from the instant heating water outlet end 210 to the instant heating connection end 420 of the water outlet device 400, and then flows out through the water outlet nozzle 410 of the water outlet device 400, so as to output hot water for the user. It should be noted that the cold water and hot water are only relative to the temperature of the water, that is, the temperature of the cold water is lower than that of the hot water; for example, the cold water can be ice water or normal temperature water.

[0042] For the instant heating device 200, the instant heating water outlet end 210 of the instant heating device 200 and the instant heating connection end 420 of the water outlet device 400 are fixedly connected, that is, the instant heating water outlet end 210 and the instant heating connection end 420 are not connected by a hose, so that the hose for connecting the instant heating water outlet end 210 of the instant heating device 200 to the instant heating connection end 420 of the water outlet device 400 on the traditional water dispenser can be omitted, thus reducing the use of the hose. Therefore, there is no longer a situation of water leakage caused by the loosening of the hose between the instant heating water outlet end 210 of the instant heating device 200 and the instant heating connection end 420 of the water outlet device 400, nor will there be a strange smell in the conveyed water due to the aging of the hose.

[0043] Similarly, for the water tank device 300, the water tank outlet end 310 of the water tank device 300 is fixedly connected to the water tank connection end 430 of the water outlet device 400, that is, the water tank outlet end 310 and the water tank connection end 430 are not connected through a hose. Thus, the hose for connecting the water tank outlet end 310 of the water tank device 300 to the water tank connection end 430 of the water outlet device 400 on a traditional water dispenser can be omitted, thereby reducing the use of hoses. Therefore, there is no longer a situation of water leakage caused by the loosening of the hose between the water tank outlet end 310 of the water tank device 300 and the water tank connection end 430 of the water outlet device 400, nor will there be an odor in the transported water due to the aging of the hose.

[0044] In the technical solution of the present invention, by fixedly connecting the instant heating connection end 420 of the water outlet device 400 to the instant heating outlet end 210 of the instant heating device 200, and fixedly connecting the water tank connection end 430 of the water outlet device 400 to the water tank outlet end 310 of the water tank device 300, the hoses between the water outlet device 400, the instant heating device 200, and the water tank device 300 can be cancelled, thereby greatly reducing the usage amount of hoses. In this way, not only can the water leakage situation caused by the loosening of the hose be reduced, but also the problem of the odor in the transported water caused by the aging of the hose can be avoided. In addition, since the hoses between the water outlet device 400, the instant heating device 200, and the water tank device 300 are removed in the water dispenser of the present invention, the number of hoses is reduced, thereby simplifying the pipeline inside the water dispenser, reducing the complexity of the pipeline inside the water dispenser, and effectively improving the assembly efficiency of the internal components of the water dispenser.

[0045] Please refer to Figures 1 to 3 , in the above embodiment, the instant heating outlet end 210 of the instant heating device 200 can be directly fixedly connected to the instant heating connection end 420 of the water outlet device 400, or can be fixedly connected to the instant heating connection end 420 of the water outlet device 400 through a rigid pipe 500. Specifically, it can be designed according to the assembly space between the instant heating device 200 and the water outlet device 400. Similarly, the water tank outlet end 310 of the water tank device 300 can be directly fixedly connected to the water tank connection end 430 of the water outlet device 400, or can be fixedly connected to the water tank connection end 430 of the water outlet device 400 through a rigid pipe 500. Specifically, it can be designed according to the assembly space between the water tank device 300 and the water outlet device 400. However, it should be noted that the rigid pipe 500 can be arranged in a bent pipe shape (such as the hot water tank adapter pipe 510) or in a straight pipe shape (such as the water tank adapter pipe 520). The rigid pipe 500 should be made of a rigid material so that the rigid pipe 500 has better strength and is not easily deformed or aged.

[0046] Please refer to Figure 1 ,Figure 3 and Figure 4 In one embodiment, the instant heating water inlet end 220 of the instant heating device 200 is usually disposed at its bottom and is communicated with the water tank device 300; while the instant heating water outlet end 210 is disposed at the top of the instant heating device 200. When a user takes hot water, the water in the water tank device 300 is conveyed from the instant heating water inlet end 210 at the bottom of the instant heating device 200 into the interior of the instant heating device 200, and then the hot water inside the instant heating device 200 is squeezed upward, so that the hot water in the instant heating device 200 is squeezed out from the instant heating water outlet end 210 at the top of the instant heating device 200. However, the instant heating water outlet end 210 at the top of the instant heating device 200 extends upward, while the instant heating connection end 420 of the water outlet device 400 extends backward, making it difficult to align and connect the instant heating water outlet end 210 of the instant heating device 200 and the instant heating connection end 420 of the water outlet device 400, and the operation is inconvenient.

[0047] Please refer to Figure 3 、 Figure 4 and Figure 6 In view of the above problems, in this embodiment, the water dispenser further includes a hot water tank adapter 510. One end of the hot water tank adapter 510 is connected to the instant heating water outlet end 210 of the instant heating device 200, and the other end of the hot water tank adapter 510 is connected to the instant heating connection end 420 of the water outlet device 400.

[0048] Specifically, the hot water tank adapter 510 is designed in a bent tube shape, so that the two ends of the hot water tank adapter 510 extend forward and downward respectively, thereby forming two insertion interfaces 501 opened in different directions at the two ends of the hot water tank adapter 510; wherein, one of the insertion interfaces 501 of the hot water tank adapter 510 is opened downward for the instant heating water outlet end 210 of the instant heating device 200 to be inserted and connected; the other insertion interface 501 of the hot water tank adapter 510 is opened forward for the instant heating connection end 420 of the water outlet device 400 to be inserted and connected. The hot water tank adapter 510 is made of a rigid material, so that the hot water tank adapter 510 has a greater strength, thereby ensuring stable connection between the hot water tank adapter 510 and the instant heating water outlet end 210 of the instant heating device 200 and the instant heating connection end 420 of the water outlet device 400, and it is difficult to easily loosen and disconnect.

[0049] Please refer to Figure 4 、 Figure 6 and Figure 8, further, the hot tank adapter 510 can be arranged in an L-shaped or C-shaped curved tube shape. Specifically in the present embodiment, the hot tank adapter 510 is arranged in an L-shaped curved tube shape. The hot tank adapter 510 includes a vertical tube body 511 extending vertically, and a horizontal tube body 512 extending from the upper end of the vertical tube body 511 toward the water outlet device 400; wherein the vertical tube body 511 is connected to the instant hot water outlet end 210, and the horizontal tube body 512 is connected to the instant hot water connection end 420.

[0050] Specifically, the upper end of the vertical tube body 511 of the hot tank adapter 510 is connected to the rear end of the horizontal tube body 512, so that the vertical tube body 511 and the horizontal tube body 512 are connected and configured to form an L shape. The hot tank adapter 510 forms a plug-in port 501 open downward at the lower end of the vertical tube body 511, and the plug-in port 501 is correspondingly inserted and connected to the instant hot water outlet end 210 of the instant hot water device 200. The hot tank adapter 510 forms a plug-in port 501 open forward at the front end of the horizontal tube body 512, and the plug-in port 501 is correspondingly inserted and connected to the instant hot water connection end 420 of the instant hot water device 200.

[0051] As for the fixing method of the plug-in port 501 of the vertical tube body and the hot water outlet end 210 of the water outlet device 400, it can be fixed by interference fit, or welded by welding materials, or bonded by sealant (such as silicone), and of course, it can also be fixed by threading. The fixing method of the horizontal tube body 512 and the hot connection end 420 of the water outlet device 400 can also be fixed by interference fit, or welded by welding materials, or bonded by sealant (such as silicone), and of course, it can also be fixed by threading.

[0052] See also Figure 3 , Figure 4 and Figure 8 In this embodiment, the vertical tube body 511 and the horizontal tube body 512 are integrally formed; the plug-in interface 501 at the lower end of the vertical tube body 511 is inserted and connected with the instant hot water outlet end 210 of the instant hot water device 200, and the plug-in interface 501 of the vertical tube body 511 is interference fit with the instant hot water outlet end 210; the plug-in interface 501 at the front end of the horizontal tube body 512 is inserted and connected with the instant hot water connection end 420 of the water tank device 300, and the plug-in interface 501 of the horizontal tube body 512 is interference fit with the instant hot water connection end 420.

[0053] In one embodiment, considering that the water tank device 300 is located above the instant heating device 200, for the convenience of arranging the hot water tank transfer pipe 510, optionally, an assembly area is spaced between the water tank device 300 and the instant heating device 200; the hot water tank transfer pipe 510 is located in the assembly area. It is worth mentioning that the hot water tank transfer pipe 510 is connected to the instant heating water outlet end 210 of the instant heating device 200, which is equivalent to connecting and fixing the hot water tank transfer pipe 510 and the instant heating device 200, making it difficult for the hot water tank transfer pipe 510 to become loose. Since the hot water tank transfer pipe 510 is arranged in the assembly area between the instant heating device 200 and the water tank device 300, it does not occupy the space between the instant heating device 200 or the water tank device 300 and the front shell 110 of the housing 100, that is, it does not occupy the front-to-back space of the water dispenser. In this way, the thickness of the water dispenser can be correspondingly reduced, which is beneficial to the thin design of the water dispenser.

[0054] It is considered here that when the water dispenser shakes greatly, the hot water tank transfer pipe 510 may also shake accordingly, which may affect the stability of the connection between the hot water tank transfer pipe 510 and the instant heating device 200. Therefore, in order to improve the installation stability of the hot water tank transfer pipe 510, optionally, the hot water tank transfer pipe 510 is fixedly connected to the bottom of the water tank device 300, so that the part of the hot water tank transfer pipe 510 other than its two insertion interfaces 501 is fixed to the water tank device 300, that is, the hot water tank transfer pipe 510 and the water tank device 300 are assembled into one body. During assembly, the water tank device 300 is directly arranged above the instant heating device 200, and then the lower end of the hot water tank transfer pipe 510 at the bottom of the water tank device 300 is correspondingly inserted and connected to the instant heating water outlet end 210 of the instant heating device 200, and finally the front end of the hot water tank transfer pipe 510 is connected to the instant heating connection end 420 of the water outlet device 400. In this way, it is equivalent to fixedly connecting the hot water tank transfer pipe 510 to both the instant heating device 200 and the water tank device 300, thereby doubly restricting the movement of the hot water tank transfer pipe 510 and making it more difficult for the hot water tank transfer pipe 510 to move and become loose.

[0055] Regarding the material of the hot water tank adapter pipe 510, the hot water tank adapter pipe 510 is made of a rigid material, and the rigid material can be selected as a metal material; the metal material can be stainless steel, copper and its alloys, aluminum and its alloys, etc., so that the hot water tank adapter pipe 510 has better strength and is not easily deformed or aged. Specifically herein, the hot water tank adapter pipe 510 is made of a metal material. It can be understood that the hot water tank adapter pipe 510 can be integrally formed with the water tank device 300; the hot water tank adapter pipe 510 can also be separately manufactured and then connected and fixed to the water tank device 300, and the connection method can be welded connection or sealed connection with a sealant (such as silicone).

[0056] Please refer to Figure 3 、 Figure 4 and Figure 8 , based on any of the above embodiments, the water tank water outlet end 310 is usually arranged at the bottom of the water tank device 300, so that cold water can be output to the water outlet device 400 by relying on the self-gravity of the water in the water tank device 300. The water tank water outlet end 310 of the water tank device 300 can be opened at the bottom wall or the lower end of the side wall of the water tank device 300. Specifically herein, the water tank water outlet end 310 of the water tank device 300 is arranged on the bottom wall of the water tank device 300 and opens forward. The water tank connection end 430 of the water outlet device 400 opens backward, so as to just face the water tank water outlet end 310 of the water tank device 300, and then the two are correspondingly inserted and connected.

[0057] Here, considering that the length of the water tank water outlet end 310 of the water tank device 300 and / or the water tank connection end 430 of the water outlet device 400 is insufficient, and it is not easy to directly insert and connect the two. In view of this, in this embodiment, the water dispenser further includes a water tank adapter pipe 520. One end of the water tank adapter pipe 520 is connected to the water tank water outlet end 310 of the water tank device 300, and the other end of the water tank adapter pipe 520 is connected to the water tank connection end 430 of the water outlet device 400.

[0058] Specifically, the water tank adapter pipe 520 extends in a straight pipe shape along the front-rear direction; an insertion interface 501 that opens backward is formed at the rear end of the water tank adapter pipe 520, and this insertion interface 501 is connected to the water tank water outlet end 310 of the water tank device 300; an insertion interface 501 that opens backward is formed at the front end of the water tank adapter pipe 520, and this insertion interface 501 is connected to the water tank connection end 430 of the water outlet device 400.

[0059] Optionally, the water tank adapter pipe 520 is fixed to the bottom of the water tank device 300, and at least a part of the water tank adapter pipe 520 is accommodated in the assembly area between the water tank device 300 and the instant heating device 200. Since at least a part of the water tank adapter pipe 520 is located in the assembly area between the instant heating device 200 and the water tank device 300, the water tank adapter pipe 520 does not occupy the space between the instant heating device 200 or the water tank device 300 and the front shell 110 of the housing 100, that is, it does not occupy the front-to-back space of the water dispenser. Thus, the thickness of the water dispenser can be correspondingly reduced, which is beneficial to the thin design of the water dispenser.

[0060] Regarding the material of the water tank adapter pipe 520, the water tank adapter pipe 520 can also be made of a hard material, and the hard material can be selected as a metal material; the metal material can be stainless steel, copper and its alloys, aluminum and its alloys, etc., so that the water tank adapter pipe 520 has better strength and is not prone to deformation or aging. Specifically here, the water tank adapter pipe 520 is made of a metal material. It can be understood that the water tank adapter pipe 520 can be integrally formed with the water tank device 300; the water tank adapter pipe 520 can also be manufactured separately and then connected and fixed to the water tank device 300, and its connection method can be welding connection or sealing connection with a sealant (such as silicone).

[0061] Please refer to Figure 3 , Figure 4 and Figure 8 , based on any of the above embodiments, as introduced above, two insertion interfaces 501 are provided at both ends of the hot water tank adapter pipe 510, and the two insertion interfaces 501 are respectively adapted for insertion connection with the instant heating water outlet end 210 of the instant heating device 200 and the instant heating connection end 420 of the water outlet device 400. To ensure the sealing performance of the two insertion interfaces 501 of the hot water tank adapter pipe 510 with the instant heating water outlet end 210 of the instant heating device 200 and the instant heating connection end 420 of the water outlet device 400, optionally, a sealing sleeve 600 is wrapped around the circumferential side wall of the insertion interface 501 of the hot water tank adapter pipe 510.

[0062] Specifically here, sealing sleeves 600 are wrapped around the circumferential side walls of the two insertion interfaces 501 of the hot water tank adapter pipe 510. The circumferential side wall of the insertion interface 501 is wrapped with a sealing sleeve 600, which should be understood that the sealing sleeve 600 is at least partially wrapped on the inner wall surface of the circumferential side wall and also partially wrapped on the outer wall surface of the circumferential side wall. In this way, not only can the connection stability between the sealing sleeve 600 and the hot water tank adapter pipe 510 be improved, but also the contact and cooperation area between the sealing sleeve 600 and the instant heating water outlet end 210 of the instant heating device 200 and the instant heating connection end 420 of the water outlet device 400 can be increased, thereby enhancing the sealing effect.

[0063] Similarly, two insertion interfaces 501 are provided at both ends of the water tank adapter pipe 520, and the two insertion interfaces 501 are respectively adapted to be inserted and connected to the water tank water outlet end 310 of the water tank device 300 and the water tank connection end 430 of the water outlet device 400. To ensure the sealing performance of the insertion connection between the two insertion interfaces 501 of the water tank adapter pipe 520 and the water tank water outlet end 310 of the water tank device 300 and the water tank connection end 430 of the water outlet device 400, optionally, a sealing sleeve 600 is wrapped around the circumferential side wall of the insertion interface 501 of the water tank adapter pipe 520.

[0064] Specifically herein, the circumferential side walls of the two insertion interfaces 501 of the water tank adapter pipe 520 are both wrapped with a sealing sleeve 600. The circumferential side wall of the insertion interface 501 is wrapped with a sealing sleeve 600, which should be understood that the sealing sleeve 600 is at least partially wrapped on the inner wall surface of the circumferential side wall and also partially wrapped on the outer wall surface of the circumferential side wall. In this way, not only can the connection stability between the sealing sleeve 600 and the water tank adapter pipe 520 be improved, but also the contact and cooperation area between the sealing sleeve 600 and the water tank water outlet end 310 of the water tank device 300 and the water tank connection end 430 of the water outlet device 400 can be increased, thereby enhancing the sealing effect.

[0065] Please refer to Figure 4 、 Figure 5 and Figure 8 For the specific structure of the above-mentioned sealing sleeve 600, there can be various design methods, and no specific restrictions are set here. In this embodiment, the sealing sleeve 600 includes an inner sealing layer 610 and an outer sealing layer 620. One end where the inner sealing layer 610 and the outer sealing layer 620 face each other is closed, so as to form an annular groove 630 between the inner sealing layer 610 and the outer sealing layer 620. The annular groove 630 is adapted to be inserted and connected to the circumferential side wall of the insertion interface 501 of the water tank adapter pipe 520 or the hot water tank adapter pipe 510.

[0066] Taking the hot water tank adapter pipe 510 as an example, when the sealing sleeve 600 is installed on the insertion interface 501 of the hot water tank adapter pipe 510, the annular groove 630 of the sealing sleeve 600 is aligned with the circumferential side wall of the insertion interface 501 of the hot water tank adapter pipe 510, and the circumferential side wall of the insertion interface 501 of the hot water tank adapter pipe 510 is correspondingly inserted into the annular groove 630 of the sealing sleeve 600, so that the sealing sleeve 600 wraps the circumferential side wall of the insertion interface 501. In this way, the inner sealing layer 610 and the outer sealing layer 620 of the sealing sleeve 600 are equivalent to being clamped on the inner and outer surfaces of the circumferential side wall of the insertion interface 501, making the sealing sleeve 600 not easily fall off from the hot water tank adapter pipe 510.

[0067] After assembly, a sealing sleeve 600 is located at one of the insertion interfaces 501 of the hot water tank adapter pipe 510. The inner sealing layer 610 of the sealing sleeve 600 is in sealing contact with the outer peripheral surface of the instant heating water outlet end 210 of the instant heating device 200. And for the sealing sleeve 600 located at the other insertion interface 501 of the hot water tank adapter pipe 510, the inner sealing layer 610 of this sealing sleeve 600 is in sealing contact with the outer peripheral surface of the instant heating connection end 420 of the water outlet device 400.

[0068] As for the assembly method of the sealing sleeve 600 and the insertion interface 501 of the water tank adapter pipe 520, reference can be made to the assembly method of the sealing sleeve 600 and the insertion interface 501 of the hot water tank adapter pipe 510, which will not be elaborated here one by one.

[0069] Please refer to Figure 4 、 Figure 5 and Figure 8 . Further, to improve the sealing performance of the sealing sleeve 600, a plurality of annular sealing ribs 611 are convexly provided on the inner peripheral surface of the inner sealing layer 610, and the plurality of annular sealing ribs 611 are arranged at intervals along the axial direction of the sealing sleeve 600. Specifically, a plurality of annular sealing ribs 611 arranged at intervals are convexly provided on the inner peripheral surface of the inner sealing layer 610, and the plurality of annular sealing ribs 611 are arranged at intervals along the axial direction of the sealing sleeve 600; among them, the plurality of annular sealing ribs 611 are arranged at equal intervals; or, the plurality of annular sealing ribs 611 are arranged at unequal intervals. In this way, the inner sealing layer 610 of the sealing sleeve 600 can be in close contact with the outer peripheral surface of the instant heating water inlet end 210 or the water outlet end inserted therein through the annular sealing ribs 611, effectively enhancing the sealing effect.

[0070] Taking the insertion of the hot water tank adapter pipe 510 and the instant heating water outlet end 210 of the instant heating device 200 as an example, after the instant heating water outlet end 210 of the instant heating device 200 is inserted into the downwardly open insertion interface 501 of the hot water tank adapter pipe 510, the outer peripheral surface of the instant heating water outlet end 210 of the instant heating device 200 is in contact with the inner sealing layer 610 of the sealing sleeve 600 wrapped around this insertion interface 501, and the annular sealing ribs 611 on the inner sealing layer 610 tightly abut against the outer peripheral surface of the instant heating water outlet end 210 of the instant heating device 200, thereby effectively sealing the gap between the instant heating water outlet end 210 of the instant heating device 200 and the insertion interface 501 of the hot water tank adapter pipe 510, and effectively enhancing the sealing performance at the connection between the two.

[0071] Further, the insertion interface 501 includes a first circumferential wall 5011 and a second circumferential wall 5012 connected to the first circumferential wall 5011. The inner diameter of the second circumferential wall 5012 is smaller than the inner diameter of the inner connection part; the second circumferential wall 5012 is inserted into the annular slot of the sealing sleeve 600. It should be noted that the insertion interface 501 may be the insertion interface 501 of the hot water tank adapter pipe 510 or the insertion interface 501 of the water tank adapter pipe 520.

[0072] Here, the insertion interface 501 of the hot water tank adapter pipe 510 is mainly taken as an example for introduction. When the insertion interface 501 of the hot water tank adapter pipe 510 is inserted and connected to the instant heating water outlet end 210 of the instant heating device 200, the instant heating water outlet end 210 of the instant heating device 200 is inserted from the inner side of the first circumferential wall 5011 of the insertion interface 501 to the inner side of the second circumferential wall 5012. The outer peripheral surface of the front end of the instant heating water outlet end 210 is in interference fit and sealed with the inner sealing layer 610 of the sealing sleeve 600 wrapped on the first circumferential wall 5011, and the outer peripheral surface of the end of the instant heating water outlet end 210 is directly in contact and sealed with the inner surface of the second circumferential wall 5012, so that it is difficult to form a gap between the entire outer peripheral surface of the instant heating water outlet end 210 and the inner peripheral surface of the hot water tank adapter pipe 510, thus greatly reducing the occurrence of water leakage and greatly enhancing the sealing performance of the connection between the two.

[0073] Please refer to Figure 2 、 Figure 6 and Figure 8 Based on any of the above embodiments, to improve the firmness of the connection between the instant heating water outlet end 210 of the instant heating device 200 and the hot water tank adapter pipe 510, optionally, the instant heating water outlet end 210 of the instant heating device 200 is made of a metal material, so that the instant heating water outlet end 210 of the instant heating device 200 has better strength and is not easily bent or deformed, so as to be stably connected to the hot water tank adapter pipe 510. And because the instant heating water outlet end 210 of the instant heating device 200 is made of a metal material, the instant heating water outlet end 210 is not easily aged, so the water output from the instant heating water outlet end 210 is not easily smelled. In addition, the instant heating device 200 is usually also made of a metal material to better store high-temperature hot water. Therefore, the instant heating water outlet end 210 of the instant heating device 200 can be integrally formed with the instant heating device 200.

[0074] In one embodiment, to improve the firmness of the connection between the water outlet end 310 of the water tank device 300 and the hot water tank adapter 510, optionally, the water outlet end 310 of the water tank device 300 is made of a metal material, so that the water outlet end 310 of the water tank device 300 has better strength and is not easily bent or deformed, thereby being able to stably connect with the hot water tank adapter 510. Moreover, since the water outlet end 310 of the water tank device 300 is made of a metal material, the water outlet end 310 is not easily aged, and thus the water output from the water outlet end 310 is not easily odorous. In addition, the water tank device 300 is usually also made of a metal material to better store cold water without generating an odor. Therefore, the water outlet end 310 of the water tank device 300 can be integrally formed with the water tank device 300.

[0075] Please refer to Figure 1 , based on any of the above embodiments, the housing 100 of the water dispenser includes a front shell 110 and a rear shell 120 that encloses the installation cavity with the front shell 110; wherein, the water outlet device 400 is installed on the front shell 110. Theoretically speaking, the water outlet device 400 can be installed on the front side surface of the front shell 110, or can be installed on the left and right side surfaces of the front shell 110. Considering that users usually prefer to receive water on the front side of the water dispenser, therefore, the water outlet device 400 is installed on the front of the front shell 110.

[0076] Furthermore, the water dispenser further includes a display panel 700, and the display panel 700 is installed on the front side surface of the front shell 110; the water outlet device 400 is located behind the display panel 700. Specifically, the water outlet device 400 is installed on the front shell 110, and the instant heating connection end 420 and the water tank connection end 430 of the water outlet device 400 pass through the front shell 110 and extend into the installation cavity. The water outlet device 400 is further provided with two adjusting members 450 respectively for adjusting the cold and hot water flow path switches; the display panel 700 is provided with two installation parts 710, and the two installation parts 710 are respectively suitable for installing the two adjusting members 450.
