[0027] Reference Figure 1 In one embodiment of the present invention, a kettle 100 is provided, comprising a kettle body 10 for storing water and a switch assembly 30 connected to the kettle body 10 , through which a user can access the water stored in the kettle body 10 .

[0028] An embodiment of the present invention further provides a refrigeration device, in which the kettle 100 is applied. The refrigeration device includes a refrigeration compartment. The kettle 100 is located in the refrigeration compartment and thus has refrigerated water to meet the user's demand for cold drinking water.

[0029] In the embodiment, the kettle body 10 comprises a spout 101 arranged on the top, the spout 101 is larger than the water outlet of the switch assembly 30, so that the water outlet of the spout 101 is larger than the water outlet of the switch assembly 30 at the same time. When the user needs to take a large amount of cold water immediately, the kettle 10 can be directly taken to pour water through the spout 101; when the user needs a small amount of water or does not need to take a large amount of cold water immediately, the switch assembly 30 can be used to take water.

[0030] In the preferred embodiment, the switch assembly 30 is arranged on the installation hole 110 of the installation wall 11 of the kettle body 10. Figure 2-3 As shown in the figure, the kettle body 10 comprises an installation wall 11, the installation wall 11 is provided with an installation hole 110, the switch assembly 30 comprises a connecting pipe 31 arranged in the installation hole 110 and connected with the kettle body 10, and a sealing ring 32 sleeved on the connecting pipe 31. The sealing ring 32 is arranged to prevent water leakage in the kettle body 10.

[0031] The sealing ring 32 comprises a first sealing part 321 arranged between the connecting pipe 31 and the kettle body 10 along the axial direction, and a second sealing part 322 arranged between the connecting pipe 31 and the kettle body 10 along the radial direction. The second sealing part 322 extends into the installation hole 110 to seal the installation hole 110.

[0032] Specifically, the sealing ring 32 is sleeved on the connecting pipe 31, the sealing ring 32 and the connecting pipe 31 are coaxially arranged, the axial direction of the sealing ring 32 is also the axial direction of the connecting pipe 31, and the radial direction of the sealing ring 32 is also the radial direction of the connecting pipe 31.

[0033] The first sealing part 321 is attached to the outer wall surface of the installation wall 11 along the axial direction, the installation hole 110 has an inner wall surface, and the second sealing part 322 is clamped between the inner wall surface and the outer peripheral surface of the connecting pipe 31. In this way, the second sealing part 322 extends into the installation hole 110 and seals the connection between the connecting pipe 31 and the installation hole 110 along the radial direction, thereby forming a first sealing to prevent water from flowing out of the installation hole 110; the first sealing part 321 further abuts against the outer wall surface of the installation wall 11 along the axial direction, thereby forming a second sealing outside the installation hole 110 to further prevent water leakage.

[0034] In the preferred embodiment, the switch assembly 30 is arranged on the installation hole 110 of the installation wall 11 of the kettle body 10. Figure 4-5 As shown in the figure, the connecting pipe 31 comprises a pipe body part 311 and an annular convex rib 312 arranged on the outer periphery of the pipe body part 311. The pipe body part 311 extends into the kettle body 10 through the installation hole 110, and the annular convex rib 312 is located outside the kettle body 10. The first sealing part 321 is located between the annular convex rib 322 and the installation wall 11, and the second sealing part 322 is located between the pipe body part 311 and the installation wall 11.

[0035] The outer peripheral surface of the tube body 311 is a fastening thread. The switch assembly 30 includes a nut 33 arranged in the kettle body 10. The tube body 311 is fastened to the nut through the fastening thread, so that the connecting pipe 31 is installed and fixed to the kettle body 10.

[0036] The tube body 311 is hollow. By controlling the switch part of the switch assembly 30, the tube body 311 of the connecting tube 31 can be connected to the inside of the kettle body 10 and the outside world for the user to take water, or the connection between the connecting tube 31 and the outside world can be disconnected. In this way, the water in the kettle body 10 cannot flow out through the connecting tube 31.

[0037] As can be seen from the above, the connecting tube 31 is always connected to the interior of the kettle body 10, but not always connected to the outside world. Therefore, as long as the water in the kettle body 10 overflows the connecting tube 31, there will be water in the connecting tube 31, and the refrigerated water can be taken out. To facilitate water extraction, the connecting tube 31 is usually located at the bottom of the kettle body 10. The connecting tube 31 is often exposed to the water inside. Therefore, it is necessary to strengthen the sealing of the connection between the connecting tube 31 and the kettle body 10 to prevent leakage or even water leakage.

[0038] In the prior art, the provision of a sealing ring 32 is also relatively common. However, the sealing ring 32 is only provided on the outer side of the kettle body 10, tightly blocking the outside of the mounting hole 110 in the axial direction, thereby preventing water from flowing out through the gap between the connecting tube 31 and the mounting hole 110. Therefore, the connecting tube 31 needs to provide a continuous and stable axial bonding force with the kettle body 10 to cause the sealing ring 32 to deform in the axial direction, thereby ensuring a good sealing effect.

[0039] During actual use, on the one hand, the kettle 100 is in a refrigerated environment for a long time, and needs to be cleaned with high-temperature water at regular intervals. As a result, the fastening threads and nuts of the connecting pipe 31 are prone to loosening under the shock of cold and heat; on the other hand, the fastening threads of the connecting pipe 31 will naturally have the risk of loosening under vibration transportation and long-term use; thus, the axial bonding force between the connecting pipe 31 and the kettle body 10 will be reduced, the sealing ring cannot guarantee a good sealing effect, and leakage will occur.

[0040] Therefore, in this case, the first sealing portion 321 of the sealing ring 32 blocks the mounting hole 110 on the outside, and the second sealing portion 322 further extends into the mounting hole 110 to seal the gap between the mounting hole 110 and the tube body 311. Even if the connecting tube 31 and the kettle body 10 become loose in the axial direction, it will not affect the radial cooperation of the second sealing portion 322 with the mounting hole 110 and the tube body 311, and it can still play a role in preventing leakage.

[0041] In one embodiment, the switch assembly 30 is located on a sealing gasket 34 between the nut 33 and the second sealing portion 322. The sealing gasket 34 is located on the inner side of the kettle body 10. The sealing gasket 34 is against the inner wall surface of the mounting wall 11 and against the second sealing portion 322, further improving the sealing between the switch assembly 30 and the kettle body 10, and ensuring that there is no gap between the nut 33 and the inner wall surface of the mounting wall 11.

[0042] The nut 33 has a receiving groove 330 on one side facing the sealing ring 32. The sealing gasket 34 is embedded in the receiving groove 330 to improve sealing and facilitate positioning. It is understood that the nut 33 has a threaded hole for the tube body 311 to pass through, and the receiving groove 330 is connected to the threaded hole.

[0043] In a preferred embodiment, the outer diameter of the first sealing portion 321 is not less than the outer diameter of the second sealing portion 322. The outer diameter of the second sealing portion 322 can be equal to or slightly larger than the inner diameter of the mounting hole 110 to ensure that the second sealing portion 322 can be squeezed and deformed to be inserted into the mounting hole 110.

[0044] The sealing ring 32 may be a rubber ring that can be squeezed and elastically deformed, so that the second sealing portion 322 can be compressed and positioned within the mounting hole 110, thereby achieving a better sealing effect. Figure 8 As shown, the outer diameter of the second sealing portion 322 is slightly larger than the inner diameter of the mounting hole 110. The inclined surface marked by the dotted line is the outer peripheral surface position of the second sealing portion 322 in the initial state. In fact, the outer diameter of the second sealing portion 322 is squeezed and reduced by the mounting wall 11, and the outer peripheral surface of the second sealing portion 322 shrinks to fit the inner diameter of the mounting hole 111.

[0045] The first sealing portion 311 needs to adhere to the outer wall surface of the mounting wall 11 to seal the mounting hole 110 from the outside. The outer diameter of the first sealing portion 311 should be larger than the inner diameter of the mounting hole 110, and the outer diameter of the first sealing portion 311 should be large enough to prevent it from being squeezed and deformed to be inserted into the mounting hole 110.

[0046] In one embodiment, the outer diameter of the first sealing portion 321 is larger than that of the second sealing portion 322 , and the first sealing portion 321 and the second sealing portion 322 form a step shape.

[0047] In one embodiment, combining Figure 3 、 6 -8, the outer diameter of the second sealing portion 322 gradually decreases from the outside to the inside along its axial direction, which facilitates the second sealing portion 322 to cooperate with the mounting hole 110 from the outside to the inside, and the outer periphery of the second sealing portion 322 forms an inclined matching surface with the inner wall of the mounting hole 110, which is more conducive to preventing water leakage.

[0048] The switch assembly 30 includes a cover plate 40 that is sleeved on the connecting tube 31 and located outside the kettle body 10 . The first sealing portion 321 abuts against the inner surface of the cover plate 40 , and the annular rib 321 abuts against the outer surface of the cover plate 40 .

[0049] The first sealing portion 321 is located between the kettle body 10 and the annular convex rib 321, specifically including: the first sealing portion 321 abuts inwardly against the following recessed portion 111, and directly abuts outwardly against the annular convex rib 321 (when the cover plate 40 is not provided); or, the first sealing portion 321 abuts inwardly against the following recessed portion 111, and abuts outwardly against the inner surface of the cover plate 40, while the outer surface of the cover plate 40 abuts against the annular convex rib 321.

[0050] The mounting wall 11 is provided with a recessed portion 111 around the corresponding mounting hole 110, and the cover plate 40 is installed in the recessed portion 111. The cover plate 40 does not protrude from the mounting wall 11, and has a better appearance; the cover plate 40 is used to cover the connection between the connecting pipe 31 and the mounting hole 110, and has a better appearance.

[0051] In a preferred embodiment, the cover plate 40 includes an elastic member 41 arranged on its inner side surface, and the elastic member 41 abuts the mounting wall 11 inwardly along the axial direction of the connecting tube 31, providing an elastic force along the axial direction to prevent loosening between the fastening thread and the nut during vibration transportation and long-term use. Specifically, the elastic member 41 is an elastic arm structure extending inward from the inner side surface of the cover plate 40, and the elastic arm structure abuts against the recessed portion 111 of the mounting wall 11.

[0052] In the prior art, if the fastening thread and nut of the connecting pipe 31 become loose, the sealing ring 32 will leak. In this case, on the one hand, a second sealing portion 322 of the sealing ring 32 is provided to extend into the mounting hole 110 to enhance the sealing effect; on the other hand, an elastic member 41 is provided to provide axial elastic force to prevent the fastening thread and nut from becoming loose.

[0053] The cover plate 40 has a through hole 42, which is adapted to the outer circumference of the connecting tube 31 to be sleeved and fixed to the connecting tube 31. Multiple elastic members 41 are arranged at intervals around the through hole 42 and are arranged at intervals close to the outer circumference of the connecting tube 31 to provide elastic shock-absorbing force.

[0054] The beneficial effects of the present invention are: the second sealing portion 322 of the sealing ring 32 extends into the mounting hole 110 to seal the mounting hole 110, thereby enhancing the sealing effect; the cover plate 40 is provided with an elastic member 41 to provide an axial elastic force to prevent the connecting pipe 31 from loosening from the kettle body 10, thereby ensuring that the axial binding force between the connecting pipe 31 and the nut 33 squeezes the sealing ring 32 to deform, thereby providing a better sealing effect.
