Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0033] In order to solve the above technical problems, Figure 1 and Figure 2As shown, the embodiment of the utility model provides a water inlet conversion device, including a water inlet conversion joint 2, a sealing joint 1 and a water inlet sealing connection pipe 3, the water inlet conversion joint 2 includes a first connection part 21, a second connection part 22 and a third connection part 23 that are interconnected, the third connection part 23 is used to connect to the main structure 7 of the drinking water equipment, and the second connection part 22 is used to connect to the water tank 5 of the drinking water equipment;

[0034] When the sealing joint 1 is arranged on the first connecting part 21, it is used to block the first connecting part 21; or, when the water inlet sealing connecting pipe 3 is arranged on the first connecting part 21, the water inlet sealing connecting pipe 3 is connected with the third connecting part 23 through the first connecting part 21.

[0035] It should be noted that the first connection part 21, the second connection part 22 and the third connection part 23 can all be pipe joint structures to facilitate water flow. The sealing joint 1 and the water inlet sealing connection pipe 3 can be selectively detachably connected to the first connection part 21, so that according to the use scenario, the sealing joint 1 or the water inlet sealing connection pipe 3 can be selected to be set on the first connection part 21, so as to select the water tank 5 or the external pipeline connected to the water source to supply water to the main structure 7.

[0036] The water inlet conversion device in this embodiment mainly includes a water inlet conversion joint 2, a sealing joint 1 and a water inlet sealing connection pipe 3. When water is inletted by means of a water tank 5, the sealing joint 1 is arranged on the first connection part 21 of the water inlet conversion joint 2 to block the first connection part 21. Since the first connection part 21, the second connection part 22 and the third connection part 23 are interconnected, the second connection part 22 connected to the water tank 5 transmits the water provided by the water tank 5 to the main structure 7 through the third connection part 23, so as to realize water inlet by means of the water tank 5. When it is necessary to switch to water inlet by means of an external pipeline, the water inlet sealing connection pipe 3 is arranged on the first connection part 2 1, so that the water inlet sealing connection pipe 3 is connected to the third connection part 23 through the first connection part 21, wherein the water inlet sealing connection pipe 3 is connected to the external pipeline, so that the external pipeline connected to the water source transmits the water flow of the water source to the main structure 7 through the first connection part 21 and the third connection part 23, so as to realize water inlet by adopting the external pipeline; in other words, through the water inlet conversion joint 2, the sealing joint 1 or the water inlet sealing connection pipe 3 is selected to be connected, so that the entire water inlet conversion device can select water inlet from the water tank 5 and water inlet from the external pipeline, thereby increasing the application range of the drinking water equipment, meeting the diverse needs of consumers, and having strong versatility.

[0037] In one embodiment of the present invention, Figure 3As shown, when the sealing joint 1 is arranged on the first connecting part 21, the sealing joint 1 includes a sealing member 11 and a connecting member 12, one end of the sealing member 11 is connected to one end of the connecting member 12, and the other end of the sealing member 11 is sleeved with the first connecting part 21, and the connecting member 12 is used to connect the housing 4 of the drinking water equipment.

[0038] It should be noted that, the other end of the sealing member 11 is sleeved with the first connection portion 21, thereby sealing the first connection portion 21 through the sealing member 11, so that the second connection portion 22 connected to the water tank 5 can only allow the water in the water tank 5 to enter the main structure 7 through the third connection portion 23, so as to supply water to the main structure 7 through the water tank 5, and at the same time, the water transported by the second connection portion 22 connected to the water tank 5 can be prevented from flowing out of the first connection portion 21, so as to avoid leakage.

[0039] The housing 4 of the drinking water device is connected via the connector 12, regardless of whether water is supplied by means of a water tank 5, for example, the sealing member 11 is sleeved with the first connecting portion 21, or water is supplied by means of an external pipeline, for example, after the sealing member 11 is removed from the first connecting portion 21, the water source is connected to the third connecting portion 23 via the external pipeline via the first connecting portion 21, and the housing 4 can be connected via the connector 12, so that the housing 4 provides an installation basis for the entire sealing joint 1 to prevent the sealing joint 1 from falling or being lost when not in use.

[0040] Specifically, the connecting member 12 and the shell 4 can be connected in the following manner. For example, the connecting member 12 is a card joint, and a mounting hole is provided on the shell 4. The card joint and the mounting hole are connected by card connection to realize the movable installation of the entire sealing joint 1 on the shell 4. When it is necessary to remove the sealing member 11 from the first connecting part 21, or to sleeve the sealing member 11 with the first connecting part 21, it is only necessary to manually operate the connecting member 12 to rotate relative to the shell 4 so that the sealing member 11 is detached from or sleeved on the first connecting part 21.

[0041] In an embodiment of the present invention, the sealing member 11 is a sleeve structure with one end closed, or the sealing member 11 is a cylindrical structure.

[0042] It should be noted that if the sealing member 11 is a sleeve structure with one end closed, the other end of the sleeve structure is open, so the sleeve structure can be installed on the outside of the first connecting part 21 through one end of the opening, or the sleeve structure can be embedded in the inside of the first connecting part 21 through one end of the opening. Both methods can seal the first connecting part 21 through the other end of the sleeve structure that is closed.

[0043] If the sealing member 11 is a cylindrical structure, the sealing member 11 can be installed inside the first connecting portion 21 by embedding to seal the first connecting portion 21. Figure 3shown.

[0044] Specifically, the sealing member 11 and the connecting member 12 may be an integrally formed structure, thereby improving the mechanical strength of the sealing joint 1 and correspondingly extending its service life.

[0045] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the central axes of the first connection portion 21 and the third connection portion 23 coincide with each other, and the extension direction of the second connection portion 22 is arranged at an angle to the central axis of the first connection portion 21;

[0046] The water inlet sealing connecting pipe 3 includes a first connecting pipe 31. When the water inlet sealing connecting pipe 3 is arranged on the first connecting part 21, the first connecting pipe 31 is embedded in the first connecting part 21, and the first connecting pipe 31 extends to the third connecting part 23, so that the first connecting pipe 31 can block the connection between the second connecting part 22 and the first connecting part 21 and the third connecting part 23 while connecting to the third connecting part 23.

[0047] It should be noted that when water needs to be supplied through a water source connected to an external pipeline, the first connecting pipe 31 can be embedded in the first connecting portion 21. Since the central axes of the first connecting portion 21 and the third connecting portion 23 coincide with each other, the extension direction of the second connecting portion 22 is set at an angle with the central axis of the first connecting portion 21, so that the first connecting pipe 31 is embedded in the first connecting portion 21 and extends to the third connecting portion 23, so that the interior of the first connecting pipe 31 is connected to the third connecting portion 23, and the outer wall of the first connecting pipe 31 can be used to block the second connecting portion 23. The connection between the connection part 22 and the first connection part 21 and the third connection part 23 is such that the pipeline for the water tank 5 to supply water to the main structure 7 through the second connection part 22 via the third connection part 23 is blocked by the first connecting pipe 31, so that the water source supplies water to the main structure 7 through the first connecting pipe 31 of the water inlet sealing connection pipe 3 via the third connection part 23, thereby realizing the water source to enter the water through an external pipeline to meet the needs of consumers; wherein, the above-mentioned water supply using the water source through an external pipeline can be applicable to the following scenarios, such as no water inside the water tank 5, or the water tank 5 leaks.

[0048] Specifically, the first connecting pipe 31 can be embedded in the first connecting portion 21 in the following manners, such as by direct insertion, or by rotation. The water source can be a faucet with running water, or a water tower.

[0049] In one embodiment of the present invention, Figure 4 and Figure 5As shown, the water inlet sealing connecting pipe 3 also includes a second connecting pipe 32 , one end of the second connecting pipe 32 is used to connect to an external pipeline, and the other end of the second connecting pipe 32 is connected to the first connecting pipe 31 .

[0050] It should be noted that when water is fed in through an external pipeline connected to a water source, the first connecting pipe 31 of the water inlet sealing connecting pipe 3 can be embedded in the first connecting part 21, and the second connecting pipe 32 connected to the first connecting pipe 31 is connected to the external pipeline. At this time, the water flow output by the water source is transmitted to the main structure 7 through the external pipeline, the second connecting pipe 32, the first connecting pipe 31 and the third connecting part 23 in sequence. Among them, since the first connecting pipe 31 is embedded in the first connecting part 21 and the first connecting pipe 31 extends to the third connecting part 23, the outer wall of the first connecting pipe 31 blocks the connection between the second connecting part 22 and the first connecting part 21 and the third connecting part 23, so that the water path between the water tank 5, the second connecting part 22, the third connecting part 23 and the main structure 7 is blocked, thereby realizing water supply using a water source.

[0051] Specifically, the first connecting pipe 31 and the second connecting pipe 32 may be an integrally formed structure, thereby not only improving the mechanical strength of the water inlet sealing connecting pipe 3 , but also improving the convenience of connecting with the first connecting portion 21 .

[0052] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the water inlet sealing connecting pipe 3 also includes a limiting pipe 33, which is arranged between the first connecting pipe 31 and the second connecting pipe 32, and the first connecting pipe 31 and the second connecting pipe 32 are respectively connected to the limiting pipe 33, and the outer diameter of the limiting pipe 33 is greater than the diameter of the first connecting part 21.

[0053] It should be noted that when water is supplied by a water source, the first connecting pipe 31 is embedded in the first connecting part 21, and the second connecting pipe 32 is connected to the external pipeline. At this time, since the limiting pipe 33 is arranged between the first connecting pipe 31 and the second connecting pipe 32, and the first connecting pipe 31 and the second connecting pipe 32 are respectively connected to the limiting pipe 33, the flowing water output by the water source enters the main structure 7 through the first connecting pipe 31, the limiting pipe 33, the second connecting pipe 32, and the third connecting part 23 in sequence; in addition, the outer diameter of the limiting pipe 33 is larger than the diameter of the first connecting part 21, so that when the first connecting pipe 31 is embedded in the inside of the first connecting part 21, the limiting pipe 33 can not only prevent the first connecting pipe 31 from being embedded too deeply into the inside of the water inlet conversion joint 2, but also make it convenient for consumers to hold the limiting pipe 33, so that the first connecting pipe 31 can be embedded in or detached from the first connecting part 21, and the second connecting pipe 32 can be connected or separated from the external pipeline.

[0054] Specifically, the first connecting pipe 31 , the limiting pipe 33 and the second connecting pipe 32 may be an integrally formed structure, thereby improving the mechanical strength of the water inlet conversion joint 2 while also improving the convenience of connecting the water inlet conversion joint 2 with the first connecting portion 21 .

[0055] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the water inlet sealing connecting pipe 3 also includes a sealing ring 34, and the sealing ring 34 is arranged between the first connecting pipe 31 and the first connecting part 21, and / or the sealing ring 34 is arranged between the first connecting pipe 31 and the third connecting part 23.

[0056] It should be noted that the number of the sealing ring 34 can be one or two; a groove is provided on the first connecting pipe 31. If the number of the sealing ring 34 is one, the groove can be provided at a position on the first connecting pipe 31 corresponding to the first connecting portion 21, and the sealing ring 34 is sleeved in the groove, so that a sealing function can be played between the first connecting pipe 31 and the first connecting portion 21 to prevent water from leaking from between the first connecting pipe 31 and the first connecting portion 21; or, if the number of the sealing ring 34 is one, the groove can be provided at a position on the first connecting pipe 31 corresponding to the third connecting portion 23, and the sealing ring 34 is sleeved in the groove, so that a sealing function can be played between the first connecting pipe 31 and the third connecting portion 23 to prevent water from leaking from between the first connecting pipe 31 and the third connecting portion 23; or, in combination Figure 4 and Figure 5 As shown, if there are two sealing rings 34, a groove is respectively provided on the first communicating tube 31 at the positions corresponding to the first communicating tube 31 and the third connecting portion 23, and the two sealing rings 34 are respectively sleeved in the two grooves, so that the first communicating tube 31 and the first communicating tube 31 can be sealed, and the first communicating tube 31 and the third connecting portion 23 can be sealed to prevent water from leaking between the first communicating tube 31 and the first connecting portion 21, and between the first communicating tube 31 and the third connecting portion 23;

[0057] The utility model also provides a drinking water device, comprising a main structure 7, a water tank 5 and the water inlet conversion device as described above.

[0058] It should be noted that when the sealing joint 1 in the water inlet conversion device is arranged on the first connection part 21, water can be supplied to the main structure 7 through the water tank 5, then through the second connection part 22 and the third connection part 23; when the water inlet sealing connection pipe 3 in the water inlet conversion device is arranged on the first connection part 21, water can be supplied to the main structure 7 through an external pipeline connected to the water source, then through the first connection part 21 and the third connection part 23, so that the drinking water equipment can take in water through the internal water tank 5 and through the external pipeline, thereby meeting the diverse usage needs of consumers.

[0059] Among them, the drinking water equipment can be various drinking water equipment such as water drinking machines and water purifiers. As long as it is a drinking water equipment with a water tank, it is applicable to the present technical solution and is not specifically limited here.

[0061] The water tank 5 is detachably connected to the housing 4 .

[0062] It should be noted that, the water tank inlet joint 6 is arranged on the water tank 5 and is connected with the water tank 5, so that after the water tank inlet joint 6 is connected with the second connection part 22 of the water inlet conversion device, it is convenient for the second connection part 22 to be quickly connected with the water tank 5; the water tank 5 is detachably connected with the outer shell 4, so that when there is no water in the water tank 5, the water tank 5 can be removed from the outer shell 4, and then the water tank 5 can be moved to other places, and water can be added to the inside of the water tank 5. When a certain amount of water is added to the water tank 5, the water tank 5 can be installed on the outer shell 4 again, and then the water tank 5 can be quickly connected with the second connection part 22 through the water tank water inlet joint 6, so as to realize water supply to the main structure 7 through the water tank 5.

[0063] Specifically, the water tank inlet connector 6 is arranged on the water tank 5, so the water tank inlet connector 6 can move with the movement of the water tank 5, so that the water tank 5 can be removed or installed on the housing 4, and only the pipeline between the second connection part 22 and the water tank inlet connector 6 needs to be removed or installed, thereby realizing the convenience of connecting the second connection part 22 with the water tank 5. Among them, the water tank inlet connector 6 can be arranged at the bottom of the water tank 5, so as not to occupy other space of the main structure 7, so as to improve the space utilization of the drinking water equipment.

[0064] In addition, the water tank 5 can be detachably connected to the outer shell 4 in the following manners. For example, the water tank 5 and the outer shell 4 can be connected by snap fasteners, or by other means such as bolt fasteners, which are not specifically limited here.
