For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0052] Please refer to Figure 1 , the present utility model provides a drinking device 1. In the embodiments of the present utility model, the types of the drinking device 1 include but are not limited to water dispensers, water purifiers, and pipeline machines, and the drinking liquids provided by the drinking device 1 to users include but are not limited to water, beverages, etc. Among them, beverages can include milk, coffee, etc., and the present utility model does not limit this.

[0053] Please refer to in combination Figures 1 - 3, specifically, the drinking water device 1 includes a housing 10, a door body 20, and a rotating shaft assembly 30. Among them, the housing 10 is used to fix and accommodate various structures, electronic devices, etc. of the drinking water device 1. The housing 10 can be made of plastic, so that the overall weight of the housing 10 is lighter, the cost is lower, and it is convenient for molding, etc. Of course, the housing 10 can also be made of metal, so that the housing 10 has better structural strength; the overall shape of the housing 10 can be generally rectangular, so that the shape of the housing 10 is more regular and convenient for molding. In this embodiment, the material and shape of the housing 10 are not specifically limited.

[0054] The housing 10 has a receiving cavity and an opening communicating with the receiving cavity. The receiving cavity can be used to accommodate the water outlet joint of the drinking water device 1 or an external water bucket, etc. The shape of the opening can be rectangular or square, etc. This embodiment does not limit this. Exemplarily, the housing 10 can include a housing body (not shown in the figure) and a base 11. The base 11 is connected to the bottom of the housing body and cooperates with the housing body to define the receiving cavity and the opening. Among them, the base 11 can support the water bucket.

[0055] The door body 20 can be made of plastic or metal. When the door body 20 is made of plastic, it has the advantages of lighter weight, better corrosion resistance, and better durability, etc. This embodiment does not limit this. Among them, the material of the door body 20 can be the same as that of the housing 10, so that the appearance of the drinking water device 1 has better consistency. Among them, the shape of the door body 20 can match the shape of the opening, such as rectangular or square, etc. This embodiment does not limit this. The door body 20 is arranged at the opening to open or close the opening. For example, when the water bucket needs to be replaced, the opening can be opened through the door body 20, then the used water bucket can be taken out and a new water bucket can be replaced, and finally the opening can be closed through the door body 20. In this way, the door body 20 can block and protect the water bucket, etc., and it is also convenient for the user to open or close the opening.

[0056] The rotating shaft assembly 30 can realize the relative rotation between the door body 20 and the housing 10, that is, the rotating shaft assembly 30 is fixedly connected to one of the housing 10 and the door body 20 and rotatably connected to the other of the housing 10 and the door body 20.

[0057] During the research and development process, the inventor discovered that if the door body 20 is provided with a rotating shaft assembly 30 on both sides along its height direction XX, and the two rotating shaft assemblies 30 are fixed as a whole relative to the door body 20, it will cause that when the door body 20 and the casing 10 are assembled, after the rotating shaft assembly 30 on one side of the door body 20 is connected to the casing 10, the rotating shaft assembly 30 on the other side of the door body 20 will interfere with the casing 10, thereby making it impossible to achieve complete assembly of the door body 20 and the casing 10. If only a rotating shaft assembly 30 fixed relatively to the door body 20 is provided on the upper side of the door body 20 along its height direction XX, and the door body 20 is connected to the casing 10 by screws on the lower side along its height direction XX, and the screw includes a threaded section and a rotating shaft section, then the screw needs to first penetrate the casing 10 from the bottom of the casing 10 from top to bottom, and at the same time as the threaded section is threadedly connected to the casing 10, the rotating shaft section is exposed outside the casing 10 and is rotatably connected to the door body 20. However, in this assembly form, the staff needs to tip over the casing 10 to realize the assembly of the screw, and the assembly is relatively complicated. In addition, the screw is prone to slippage between the threaded section and the casing 10 after long-term disassembly and assembly, which makes the screw unable to be disassembled.

[0058] Based on this, in order to solve the above assembly problem, the shaft assembly 30 of this embodiment includes a sleeve 31 and a telescopic shaft 32. The sleeve 31 can be a metal part or a plastic part. When the sleeve 31 is a metal part, the sleeve 31 has advantages such as good strength and stable connection, and when the sleeve 31 is a plastic part, the sleeve 31 has advantages such as easy molding, etc. The sleeve 31 can be set in a cylindrical shape, which is not limited in this embodiment. The sleeve 31 is fixedly connected to one of the door body 20 and the housing 10.

[0059] The telescopic shaft 32 can be a metal part or a plastic part. When the telescopic shaft 32 is a metal part, the telescopic shaft 32 has advantages such as better strength and better wear resistance, and when the telescopic shaft 32 is a plastic part, the telescopic shaft 32 has advantages such as easy molding, and the telescopic shaft 32 can be set roughly in a cylindrical shape. The telescopic shaft 32 is telescopically arranged in the sleeve 31. It can be understood that the telescopic shaft 32 can move relative to the sleeve 31 along its axial direction to achieve telescoping, and can be at least partially retracted into the sleeve 31 and partially extended out of the sleeve 31. The telescopic shaft 32 can utilize the elastic force of the elastic member 33 to partially retract from the shaft sleeve 31, or the outer wall of the telescopic shaft 32 can be provided with a locking member, and the side wall of the shaft sleeve 31 is provided with a locking through hole. During the assembly process of the door body 20 and the housing 10, the locking member is locked in the locking through hole, so that at least part of the telescopic shaft 32 is retracted into the shaft sleeve 31. After the door body 20 and the housing 10 are assembled, the staff drives the locking member to disengage from the locking through hole, so that part of the telescopic shaft 32 can extend out of the shaft sleeve 31. This embodiment does not limit this. The telescopic shaft 32 is rotatably connected to the other of the door body 20 and the housing 10.

[0060] During the assembly process of the door body 20 and the housing 10, the telescopic rotating shaft 32 can be at least partially retracted into the shaft sleeve 31; after the door body 20 and the housing 10 are assembled, the telescopic rotating shaft 32 can partially extend out of the shaft sleeve 31 and be inserted into the other one of the door body 20 and the housing 10, so that the door body 20 can rotate relative to the housing 10 around the axial direction of the telescopic rotating shaft 32.

[0061] It can be understood that when assembling the door body 20 and the housing 10, it is only necessary to first fixedly connect the shaft sleeve 31 to one of the door body 20 and the housing 10, and after the door body 20 and the housing 10 are aligned and assembled, then make the telescopic rotating shaft 32 partially extend out of the shaft sleeve 31 and be inserted into the other one of the door body 20 and the housing 10, so that the rotatable connection between the door body 20 and the housing 10 can be realized, thus the assembly is convenient and the efficiency is relatively high, and even if the door body 20 and the housing 10 are disassembled and assembled repeatedly for many times, the rotating shaft structure is not easily damaged and has strong durability.

[0062] Moreover, based on the setting that the telescopic rotating shaft 32 can be retracted into the shaft sleeve 31 during the assembly process of the door body 20 and the housing 10, it can be ensured that the telescopic rotating shaft 32 will not interfere with the door body 20 or the housing 10, preventing any side of the two sides of the door body 20 from interfering with the housing 10 and thus preventing the situation where the complete assembly of the door body 20 and the housing 10 cannot be achieved.

[0063] Please refer to Figure 1 , in some embodiments, the rotating shaft assembly 30 is connected to one side of the door body 20 along its height direction XX, and the drinking water device 1 further includes a fixed rotating shaft 40 which is fixedly connected to the other side of the door body 20 along its height direction XX and is rotatably connected to the housing 10. Among them, the fixed rotating shaft 40 and the door body 20 can be an integral structure, that is, the fixed rotating shaft 40 and the door body 20 can be manufactured integrally in one molding, so that it is convenient for processing and manufacturing while improving the connection strength between the two. Of course, the fixed rotating shaft 40 and the door body 20 can be a split structure, and this embodiment does not limit this.

[0064] It can be understood that during the actual assembly process, the fixed rotating shaft 40 fixed to one side of the door body 20 can be assembled with the housing 10 first. During this process, the telescopic rotating shaft 32 can be at least partially retracted into the shaft sleeve 31, so it will not interfere with the housing 10. Then, after the door body 20 and the housing 10 are assembled, the telescopic rotating shaft 32 can partially extend out of the shaft sleeve 31, and the telescopic rotating shaft 32 is inserted into the housing 10 or the door body 20, so that the door body 20 can rotate relative to the housing 10 around the axial direction of the telescopic rotating shaft 32. In this way, the assembly is convenient and the efficiency is relatively high.

[0065] Please refer to in combination Figures 1 - 3, in some embodiments, the bushing 31 forms a socket groove 311 with an opening 312. The rotating shaft assembly 30 further includes an elastic member 33, where the elastic member 33 can be a compression spring or a spring sheet, and this embodiment does not limit this.

[0066] The elastic member 33 is disposed in the socket groove 311, and one end of the elastic member 33 extends out of the opening 312 and abuts against the telescopic rotating shaft 32, and the other end of the elastic member 33 abuts against the bottom wall of the socket groove 311. Wherein, during the assembly process of the door body 20 and the casing 10, the elastic member 33 will be compressed by the cooperation of the telescopic rotating shaft 32 and the bushing 31, and after the door body 20 and the casing 10 are assembled, the elastic member 33 can recover its elastic deformation to increase the elastic force to drive the telescopic rotating shaft 32 to partially extend out of the socket groove 311, and then be inserted into the other of the door body 20 and the casing 10.

[0067] In this way, in this embodiment, the telescopic rotating shaft 32 can directly utilize the elastic force generated by the elastic member 33 to achieve extension without manual operation, and the overall structure of the rotating shaft assembly 30 is relatively simple, which is convenient for manufacturing production and assembly.

[0068] Please refer to Figures 1 - 3 , in some embodiments, the door body 20 is provided with a first connection hole 20A, the bushing 31 passes through the first connection hole 20A and is fixedly connected to the door body 20, and the casing 10 is provided with a second connection hole 10A, the telescopic rotating shaft 32 is inserted into the second connection hole 10A and is rotatably connected to the casing 10.

[0069] During the actual assembly process, the bushing 31, the elastic member 33 and the telescopic rotating shaft 32 can be assembled first, and then the bushing 31 is passed through the first connection hole 20A to fixedly connect the bushing 31 to the door body 20. At this time, the entire rotating shaft assembly 30 is fixed on the door body 20, and then the door body 20 and the casing 10 are assembled. During this process, when the telescopic rotating shaft 32 comes into contact with the casing 10, it will at least partially retract into the bushing 31. After the door body 20 and the casing 10 are aligned and assembled, the telescopic rotating shaft 32 will be aligned with the second connection hole 10A. Since the second connection hole 10A is not in contact with the telescopic rotating shaft 32 at this time, under the drive of the elastic member 33, the telescopic rotating shaft 32 will partially extend out of the bushing 31 and be inserted into the second connection hole 10A. In this way, the entire assembly process is convenient and fast, effectively improving the assembly efficiency among the casing 10, the door body 20 and the rotating shaft assembly 30.

[0070] Please refer to Figures 1 - 3, Further, the bushing 31 is in interference fit with the first connection hole 20A. Thus, only by passing the bushing 31 through the first connection hole 20A, the first connection hole 20A expands and deforms to sleeved on the bushing 31, and then the first connection hole 20A resumes its original shape to generate a tightening force on the bushing 31, realizing the quick installation of the bushing 31 and the door body 20, and the operation is convenient without borrowing additional disassembly and assembly tools.

[0071] In some cases, the door body 20 is a common part, and the diameter of the first connection hole 20A of the door body 20 is larger than the outer diameter of the bushing 31. Based on this, please refer to Figures 1 - 3 , In some embodiments, a plurality of ribs 314 are spaced on the outer sidewall of the bushing 31. The ribs 314 and the bushing 31 can be an integral structure, so as to improve the connection strength between the two and reduce the assembly steps. It can be understood that the overall outer diameter of the ribs 314 and the bushing 31 is larger than the diameter of the first connection hole 20A, so that the bushing 31 is in interference fit with the first connection hole 20A through the plurality of ribs 314.

[0072] In this way, there is no need to specifically design the door body 20 for fitting the bushing 31, and a common part can be used as the door body 20 of the drinking water device 1 of the present invention, effectively reducing the manufacturing cost.

[0073] Please continue to refer to Figures 1 - 3 , Further, each rib 314 includes a guiding section 3141 and an abutting section 3142, and the guiding section 3141 is connected to the abutting section 3142. The guiding section 3141 is used to guide the abutting section 3142 into the first connection hole 20A, and the abutting section 3142 abuts against the hole sidewall of the first connection hole 20A.

[0074] It can be understood that the surface of the guiding section 3141 facing away from the bushing 31 forms a guiding surface, and the guiding surface can be in guiding cooperation with the hole sidewall of the first connection hole 20A to guide the abutting section 3142 into the first connection hole 20A. In this way, the assembly of the bushing 31 and the door body 20 is smoother and more convenient.

[0075] Of course, in other embodiments, it can also be that the hole sidewall of the first connection hole 20A is formed with a guiding surface, and the assembly smoothness of the bushing 31 and the door body 20 is improved through the cooperation between the guiding surface and the rib 314.

[0076] In some embodiments, an external thread structure (not shown in the figure) is provided on the outer sidewall of the bushing 31, and an internal thread structure (not shown in the figure) is provided on the hole sidewall of the first connection hole 20A. The external thread structure and the internal thread structure are in threaded cooperation to thread-connect the bushing 31 and the first connection hole 20A.

[0077] This setting is beneficial to improving the connection stability between the bushing 31 and the door body 20, and it is relatively convenient to disassemble and assemble. When it is necessary to assemble or disassemble the bushing 31, only the bushing 31 needs to be rotated to make the external thread structure and the internal thread structure thread-connected or disconnected, and the disassembly and assembly can be realized without borrowing additional disassembly and assembly tools.

[0078] Please refer to Figures 1 - 3 In some embodiments, the bushing 31 includes a bushing main body 315 and a limiting portion 316. The bushing main body 315 is the main part of the bushing 31, which is arranged in a cylindrical shape, and the bushing main body 315 is inserted through the first connection hole 20A.

[0079] The limiting portion 316 protrudes from the outer side wall of the bushing main body 315. It can be understood that the limiting portion 316 and the bushing main body 315 can be an integral structure, so that the connection strength between the two can be improved and the assembly steps of the two can be reduced. Of course, the limiting portion 316 and the bushing main body 315 can also be a split structure, and this embodiment does not limit this.

[0080] Among them, the limiting portion 316 is used to abut and limit against the outer side wall of the door body 20. On the basis that the bushing 31 is inserted through the first connection hole 20A, in this embodiment, the limiting portion 316 is used to abut and limit against the door body 20 to prevent the bushing 31 from being inserted too deep and causing the whole to be separated from the first connection hole 20A.

[0081] Please continue to refer to Figures 1 - 3 Furthermore, the limiting portion 316 extends along the circumferential direction of the bushing 31 to form a skirt structure 3161. The skirt structure 3161 is used to abut and limit against the outer side wall of the door body 20.

[0082] In this way, it is beneficial to improve the limiting effect of the limiting portion 316 and further prevent the situation that the bushing 31 is inserted too deep and causes the whole to be separated from the first connection hole 20A.

[0083] Of course, the present invention is not limited to this. In other embodiments, the limiting portion 316 is a convex block structure and includes a plurality of convex blocks. The plurality of convex blocks are arranged at intervals along the circumferential direction of the bushing 31 to abut and limit against the door body 20 through the plurality of convex blocks.

[0084] Please refer to Figure 4 In some embodiments, one end of the telescopic rotating shaft 32 has a limiting groove 321 which is open, and the elastic member 33 is arranged in the limiting groove 321 to be limited by the limiting groove 321. One end of the elastic member 33 abuts against the bottom wall of the limiting groove 321, and the other end abuts against the bottom wall of the socket groove 311.

[0085] With such a setting, the elastic member 33 can be blocked and limited by the groove wall of the limiting groove 321, preventing the elastic member 33 from shifting and disengaging from the telescopic rotating shaft 32, and further preventing the situation where the telescopic rotating shaft 32 cannot be telescoped along its axial direction, which helps to improve the durability of the rotating shaft assembly 30.

[0086] Of course, in other embodiments, it may also be that the groove side wall of the socket groove 311 forms a limiting structure, and the elastic member 33 is limited by the limiting structure. The embodiments of the present invention do not limit this.

[0087] During the actual assembly process, the elastic member 33 can be first placed in the limiting groove 321, and then the telescopic rotating shaft 32 and the shaft sleeve 31 are assembled, so as to realize the assembly of the three.

[0088] Please refer to Figures 4 - 5 , in some embodiments, an anti-disengagement structure 313 is provided between the shaft sleeve 31 and the telescopic rotating shaft 32. The anti-disengagement structure 313 is used to prevent the telescopic rotating shaft 32 from protruding out of the shaft sleeve 31 as a whole. In this way, by setting the anti-disengagement structure 313, the telescopic rotating shaft 32 and the shaft sleeve 31 can be prevented from disengaging, ensuring the stability of their connection. Furthermore, when the door body 20 rotates relative to the machine shell 10, the two can be prevented from disengaging, guaranteeing the safety of the user when rotating the door body 20.

[0089] Please refer to Figures 4 - 6 , further, the anti-disengagement structure 313 is a buckle 3131 provided in the socket groove 311, and the buckle 3131 is adjacent to the opening 312. The telescopic rotating shaft 32 includes a connecting section 322 and a rotating section 323. The connecting section 322 abuts against the elastic member 33, and the connecting section 322 is disposed in the socket groove 311. The rotating section 323 is connected to the connecting section 322, and after the door body 20 and the machine shell 10 are assembled, the rotating section 323 can protrude out of the socket groove 311 and be inserted into the machine shell 10 or the door body 20.

[0090] Wherein, the outer diameter of the connecting section 322 is larger than the outer diameter of the rotating section 323, so as to form a buckling position 324 at the junction of the two. The buckling position 324 is used for the buckle 3131 to be buckled. In this way, by the cooperation of the buckle 3131 and the buckling position 324, the connecting section 322 cannot protrude out of the socket groove 311, so that the telescopic rotating shaft 32 as a whole cannot protrude out of the shaft sleeve 31 and be separated from the shaft sleeve 31.

[0091] In other embodiments, the anti - detachment structure 313 can also be a threaded locking member. A first threaded hole is formed in the side wall of the bushing 31, and a second threaded hole is formed in the side wall of the connecting section 322. When it is necessary to enable the rotating section 323 to extend out of the socket groove 311, at this time, the threaded locking member does not pass through the first threaded hole and the second threaded hole. When at least a part of the rotating section 323 extends out of the socket groove 311 and is inserted into the housing 10 or the door body 20, at this time, the threaded locking member can be passed through the first threaded hole and the second threaded hole in sequence to achieve threaded connection, so that the telescopic rotating shaft 32 cannot continue to extend, to prevent the entire telescopic rotating shaft 32 from extending out of the bushing 31 and separating from the bushing 31. This embodiment does not limit this.

[0092] Please refer to Figures 4 - 5 , further, along the radial direction of the bushing 31, the length of the buckle 3131 is greater than or equal to 0.3 mm and less than or equal to 1 mm. In this way, while ensuring the clamping stability between the buckle 3131 and the buckling position 324, it is convenient for the assembly of the rotating shaft main body and the bushing 31.

[0093] If the length of the buckle 3131 is less than 0.3 mm, the length of the buckle 3131 is relatively short, which may easily cause the separation between the buckle 3131 and the buckling position 324. If the length of the buckle 3131 is greater than 1 mm, it will be inconvenient for the rotating shaft main body to pass through the bushing 31, and the assembly operation is relatively inconvenient.

[0094] Exemplarily, the length of the buckle 3131 can specifically be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1 mm, etc. This embodiment does not limit this.

[0095] Please refer to Figures 4 - 5 , in some structural forms, the buckle 3131 extends along the circumferential direction of the bushing 31, and at least a part of the side surface forms a guiding surface 3132. The guiding surface 3132 is used to guide the telescopic rotating shaft 32 from the open end 312 to the socket groove 311. In this way, the guiding cooperation between the guiding surface 3132 and the outer side surface of the telescopic rotating shaft 32 can be utilized to improve the convenience of the connection between the telescopic rotating shaft 32 and the bushing 31, and effectively improve the assembly efficiency of the telescopic rotating shaft 32 and the bushing 31.

[0096] Please refer to Figure 7 , in some embodiments, there are two rotating shaft assemblies 30, and the two rotating shaft assemblies 30 are connected to the opposite sides of the door body 20 along its height direction XX.

[0097] In this way, the two rotating shaft assemblies 30 can be first assembled on the door body 20, then the door body 20 can be assembled with the casing 10, and finally the telescopic rotating shafts 32 of the two rotating shaft assemblies 30 extend out of the socket grooves 311 of the shaft sleeves 31 and are inserted into the casing 10. The operation is convenient, and the telescopic rotating shafts 32 of the two rotating shaft assemblies 30 will not interfere with the door body 20.

[0098] Please refer to Figure 8 , in some embodiments, the shaft sleeve 31 extends along the height direction XX of the door body 20 and penetrates through the door body 20. There are two telescopic rotating shafts 32. The two telescopic rotating shafts 32 are respectively telescopically inserted through the opposite ends of the shaft sleeve 31 along its extending direction and are respectively inserted into the opposite sides of the casing 10. In this way, the shaft sleeve 31 can be first assembled with the door body 20, that is, the shaft sleeve 31 is inserted through the door body 20, then the two telescopic rotating shafts 32 are respectively inserted through the shaft sleeve 31, and then the door body 20 is assembled with the casing 10. After the assembly is completed, the two telescopic rotating shafts 32 will extend out of the socket grooves 311 of the shaft sleeve 31 and are inserted into the casing 10, and the telescopic rotating shafts 32 of the two rotating shaft assemblies 30 will not interfere with the door body 20.
