[0005] [Patent Document 1] China Utility Model No. 201379426 Specification [Overview of the project]
[0006] The first technical problem that the present invention aims to solve is, in light of the current state of the prior art, to provide an automatic sealing mechanism for a spout that can automatically adjust the opening and closing of the water discharge passage of the spout according to the state of the kettle itself, and that can be directly attached to the spout of the kettle, thus having high versatility.
[0007] The second technical problem that this invention aims to solve is to provide an electric kettle equipped with the above-described automatic sealing mechanism, in light of the current state of the prior art.
[0008] The present invention provides the following technical solution for solving the first technical problem described above. The automatic sealing mechanism for a spout is provided in a water discharge passage leading to a spout, and is a sealing part provided in the water discharge passage that seals the water discharge passage, the sealing part having a through hole in the center that communicates with the water discharge passage, and on the side of the sealing part located at the entrance end of the through hole, a recessed surface is provided that extends from the outer periphery of the sealing part along the radial direction of the sealing part toward the exit end of the through hole, with the through hole located at the lowest point of the recessed surface, and a plug provided movably on the side of the sealing part toward the exit end of the through hole for sealing the exit end of the through hole, and a smooth along the recessed surface on the side of the sealing part toward the entrance end of the through hole The system includes a gravity block that is movable in the groove, and a connecting rope that passes through the through hole such that a gap passage exists between the through hole and the gravity block, with both ends connected to the plug and the gravity block respectively. When the kettle is upright or inverted, the gravity block hangs down, causing the plug to seal the outlet end of the through hole and close the water discharge passage to the spout. When the kettle is dispensing hot water, the gravity block moves smoothly along the recessed surface to a position below the recessed surface, causing the plug to move away from the outlet end of the through hole, opening the through hole and opening the water discharge passage to the spout.
[0009] Preferably, the retaining ring extends outward from the outside of the sealing portion, and when the kettle is in an upright or inverted position, the inner circumferential wall of the retaining ring is in close contact with the outer circumferential wall of the plug. When the above technical proposal is used, the inner circumferential wall of the retaining ring is in close contact with the outer circumferential wall of the plug, so that water in the kettle is less likely to leak out through the gap between the plug and the sealing portion, and the sealing effect of the water discharge passage by the plug is improved.
[0010] Preferably, the plug has a frustoconical shape with a larger outer end and a smaller inner end, and the inner circumferential wall of the retaining ring and the outer circumferential wall of the plug engage and guide, and also engage and seal. Because the plug is frustoconical in shape, and the space enclosed by the inner circumferential wall of the retaining ring is also frustoconical, when the kettle body is placed upright after dispensing hot water, the plug moves in the axial direction of the retaining ring, and the frustoconical shape of the plug and retaining ring serves as a guide.
[0011] Preferably, in the axial direction of the plug, the thickness of the retaining ring is greater than the thickness of the gravity block. When the above technical proposal is used, the gravity block is restricted by the retaining ring during the hot water supply process, so that the gravity block does not detach from the internal space of the retaining ring. After the hot water supply is finished, when the kettle body is placed upright, the gravity block is easily re-engaged with the retaining ring and sealed.
[0012] Preferably, the retaining ring is provided with multiple water discharge grooves in the axial direction of the retaining ring, and the water discharge grooves are spaced apart from each other. When the kettle is in the hot water supply state, there is a gap between the outer wall of the plug and the inner wall of the retaining ring. When the above technical proposal is used, the water in the kettle flows out through the gap and then out through the water discharge grooves, and the water discharge speed from the kettle is increased by the water discharge grooves.
[0013] Preferably, the sealing portion is provided with multiple discharge holes for water to flow out of the kettle. The discharge holes are spaced apart and surround the through-holes, and when the kettle is upright or inverted, the gravity block hangs down, causing the plug to seal the discharge holes. The discharge holes increase the flow rate of water discharged from the kettle.
[0014] Preferably, the recessed surface is provided with multiple water intake holes, which are spaced apart and surround the through-holes, and the water intake holes communicate with the water discharge holes. Similarly, the water discharge rate from the kettle is increased by the installation of water intake holes.
[0015] Preferably, within the sealed portion, a plurality of first retaining ribs extend inward, the first retaining ribs are provided along the radial direction of the sealed portion, the first retaining ribs are connected to each other near the center of the sealed portion to form the through-hole, and the gaps between adjacent first retaining ribs are the water absorption holes. The height of each first retaining rib near the center of the sealed portion is lower than the height of each first retaining rib at the edge of the sealed portion, and the surface of each retaining rib constitutes a recessed surface having the water discharge holes. By installing retaining ribs, the amount of material used can be reduced, costs can be lowered, and the diameter of the water absorption holes can be increased.
[0016] Preferably, the second retaining rib extends inward inside the sealing portion, is provided along the radial direction of the sealing portion, is located between adjacent first retaining ribs, and a gap is provided between one end of the second retaining rib closest to the through hole and the through hole. The additionally installed second retaining rib is intended to prevent the gravity block from falling into the gap between adjacent first retaining ribs. Furthermore, by providing a gap between the second retaining rib and the through hole, the flow rate at the water intake hole can be increased.
[0017] Preferably, a connecting ring extending radially outward is provided on the outer circumferential wall of the sealing portion, a sealing ring is provided on the side of the connecting ring closest to the spout, and a plurality of buckles extending radially outward are provided on the outer circumferential wall of the sealing portion, with the buckles being provided at equal intervals in the circumferential direction of the sealing portion. The sealing ring is positioned between the connecting ring and the buckles. In the process of installing the automatic sealing mechanism, the automatic sealing mechanism is inserted from the kettle body, the buckles are aligned with the spout inside the kettle body, and the buckles are forcibly passed through the spout. In this way, the automatic sealing mechanism can be installed on the spout, and the sealing ring comes into contact between the kettle body and the connecting ring.
[0018] Preferably, the automatic sealing mechanism further includes a spherical mesh cover, on the side of the connecting ring away from the spout, the connecting parts are provided at equal intervals in the circumferential direction of the connecting ring, and the spherical mesh cover is connected to the connecting parts.
[0019] In the present invention, another technical solution used to solve the first technical problem described above is as follows: An automatic sealing mechanism for a spout is provided in a water discharge passage leading to a spout, and the sealing part provided in the water discharge passage seals the water discharge passage, the sealing part is provided with a through hole located in the center and a water intake hole communicating with the water discharge passage, and on the side of the sealing part where the water intake end of the water intake hole is located, a recessed surface is provided that extends from the outer peripheral edge of the sealing part along the radial direction of the sealing part toward the direction of the water discharge end of the water intake hole, with the through hole located at the lowest point of the recessed surface, and a plug is provided movably on the side of the sealing part where the water discharge end of the water intake hole is located for sealing the water discharge end of the water intake hole, and the sealing part The kettle includes a gravity block that is smoothly movable along a recessed surface on the side of the water intake end of the water intake hole, and a connecting rope that passes through a through hole and has both ends connected to the plug and the gravity block, respectively. When the kettle is upright or inverted, the gravity block hangs down, causing the plug to seal the water outlet end of the water intake hole and close the water outlet passage leading to the spout. When the kettle is dispensing hot water, the gravity block moves smoothly along the recessed surface to a position below the recessed surface, causing the plug to move away from the water outlet end of the water intake hole, opening the water intake hole and the water outlet passage leading to the spout. In this embodiment, there is no gap passage between the connecting rope and the through hole, and water flows only through the water intake hole.
[0020] In the present invention, the technical solution used to solve the second technical problem described above is as follows: The electric kettle includes a kettle body and a spout, the kettle body is provided with a water outlet, the water outlet communicates with the spout, and the water outlet is provided with the automatic sealing mechanism described above.
[0021] Compared with the prior art, the present invention has the following advantages. When boiling water, when the kettle is tilted at a specific angle, the gravity block slides along the concave surface to the lowest point of the concave surface, and the plug is opened by the water flow, so that the water in the kettle flows out. When the kettle is in a vertical state or a toppled state, the gravity block hangs down, so that the plug seals the through hole and closes the water discharge passage of the spout. In the automatic sealing mechanism of the present invention, the opening and closing of the water discharge passage can be automatically performed according to the state of the kettle itself, improving the convenience in use. In addition, the automatic sealing mechanism in the present invention is directly attached to the water discharge port of the kettle, so it has high versatility, and even if it is damaged, it can be easily replaced.

Modes for Carrying Out the Invention
[0023] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings and examples. <Example 1> In FIGS. 1 to 6, preferred embodiments of the automatic sealing mechanism for the spout 102 in the present invention are shown. The automatic sealing mechanism includes a sealing part 1, a plug 2, a gravity block 3, and a connecting rope 4.
[0024] The automatic sealing mechanism can be provided at any position within the water discharge passage 102a from the internal space of the kettle 100 to the spout 102. In this embodiment, the automatic sealing mechanism is provided at the connection point between the spout 102 and the kettle body 101, i.e., at the spout 103 on the kettle body 101, which is the inlet of the spout 102. In other embodiments, the automatic sealing mechanism may be provided inside the spout 102.
[0025] As shown in Figures 2 to 6, the sealing portion 1 has a substantially cylindrical shape, and the outer circumferential wall of the sealing portion 1 is connected to the spout 103 of the kettle body 101 of the kettle 100. A through hole 10 extending in the axial direction is provided in the center of the sealing portion 1, and the through hole 10 communicates with the water discharge passage 102a. On the side surface of the sealing portion 1 facing inward towards the kettle body 101, a plurality of first retaining ribs 14 extend in the axial direction, and each first retaining rib 14 is provided along the radial direction of the sealing portion 1, and the first retaining ribs 14 are connected to each other in the center of the side surface of the sealing portion 1 to form the through hole 10. The gaps between adjacent first retaining ribs 14 are water intake holes 13. In other words, each first retaining rib 14 is formed radially, extending in the radial direction of the sealing portion 1 with the through hole 10 as the center. Multiple second retaining ribs 15 also extend axially from the side of the sealing portion 1 facing inward towards the kettle body 101. Each second retaining rib 15 is provided along the radial direction of the sealing portion 1, and the second retaining ribs 15 and the first retaining ribs 14 are provided alternately at intervals. There is a gap between one end of the second retaining rib 15 closest to the through hole 10 and the through hole 10. As shown in Figures 3 and 6, both the first retaining rib 14 and the second retaining rib 15 are provided along the radial direction of the side surface of the sealing portion 1, and the height of the first retaining rib 14 and the second retaining rib 15 gradually decreases along the radial direction toward the exit end 10b of the through hole 10 (concave toward the center), and the first retaining rib 14 and the second retaining rib 15 form a recessed surface 1a on the side surface of the sealing portion 1, and this recessed surface 1a gradually slopes along the radial direction of the sealing portion 1 toward the exit end 10b of the through hole 10, and the lowest point of this recessed surface 1a is at the location where the through hole 10 is located.
[0026] As shown in Figure 4, the side of the sealing portion 1 that is away from the inside of the kettle body 101 is provided with a plurality of discharge holes 12 for water to flow out from inside the kettle 100. The discharge holes 12 are spaced apart and surround the through hole 10. In this embodiment, the discharge holes 12 are also formed by the gaps between adjacent first retaining ribs 14. In other words, the discharge holes 12 are an extension of the water intake holes 13. A retaining ring 11 extends axially from the side of the sealing portion 1 that is away from the inside of the kettle body 101. The retaining ring 11 and the through hole 10 are provided concentrically, and the retaining ring 11 surrounds the outside of the discharge holes 12.
[0027] As shown in Figures 2 and 3, the plug 2 is movably mounted on the side of the outlet end 10b of the through hole 10 in the sealing part 1, that is, on the side of the discharge end 13b of the water intake hole 13. The gravity block 3 is movably mounted along the recessed surface 1a on the side of the inlet end 10a of the through hole 10 in the sealing part 1, that is, on the side of the water intake end 13a of the water intake hole 13. The connecting rope 4 passes through the through hole 10 and both ends are connected to the plug 2 and the gravity block 3, respectively. The plug 2 is located inside the spout 102 and the gravity block 3 is located inside the kettle body 101. Between the connecting rope 4 and the through hole 10, there may be a larger gap passage for water to pass through, or a smaller gap passage that only allows the connecting rope 4 to move. When there is a larger gap passage, as in the former case, water can pass through the gap passage and the water intake hole 13 simultaneously. In this embodiment, the gravity block 3 is spherical and easily rolls along the recessed surface 1a. One end of the connecting rope 4 is connected to the spherical gravity block 3.
[0028] When the kettle 100 is upright, or if it is accidentally tipped over, the gravity block 3 hangs down (sags downwards), causing the inner wall of the retaining ring 11 and the outer wall of the plug 2 to come into close contact, sealing the through hole 10 and the water outlet hole 12. When the kettle 100 is in the correct hot water supply state, the gravity block 3 moves along the recessed surface 1a formed by the first retaining rib 14 and the second retaining rib 15, to a position below the recessed surface 1a. At this time, the connecting rope 4 moves laterally within the through hole 10 toward the water outlet end 13b of the water intake hole 13, the plug 2 separates from the outlet end 10b of the through hole 10 and the water outlet end 13b of the water intake hole 13, and water in the kettle flows out through the gap between the plug 2 and the retaining ring 11. Conversely, after the hot water supply is complete, the connecting rope 4 moves laterally with the gravity block 3 toward one side of the water intake end 13a of the water intake hole 13, and consequently, the plug 2 moves to seal the through hole 10 and the water intake hole 13. The kettle 100 being in an upright or inverted state means that the kettle is not supplying hot water. The inclination angle in the hot water supply state is such that the through hole 10 can be positioned at the lowest point of the recessed surface 1a in the direction of gravity. During hot water supply, the gravity block 3 moves smoothly along the recessed surface 1a.
[0029] Furthermore, the retaining ring 11 is provided with a plurality of water discharge grooves 111 along the axial direction of the retaining ring 11, and the water discharge grooves 111 are spaced apart from each other. After the water inside the kettle body 101 flows out through the gap between the plug 2 and the retaining ring 11, it can be quickly discharged through the water discharge grooves 111.
[0030] Plug 2 has a frustoconical shape, and the diameter of the outer end face of plug 2 is larger than the diameter of the inner end face of plug 2. The diameter of the inner circumferential wall of the retaining ring 11 is also set to match that of plug 2.
[0031] To facilitate the connection of the automatic sealing mechanism to the kettle, a connecting ring 16 extends radially outward from the outer circumferential wall of the sealing section 1, and a sealing ring 5 is provided on the side of the connecting ring 16 closest to the spout 102. Multiple buckles 17 extend radially outward from the outer circumferential wall of the sealing section 1, and the buckles 17 are provided at equal intervals in the circumferential direction of the sealing section 1. The sealing ring 5 is positioned between the connecting ring 16 and the buckles 17. During the installation of the automatic sealing mechanism, the automatic sealing mechanism is inserted from the kettle body 101, the buckles 17 are aligned with the spout 103 inside the kettle body 101, and the buckles 17 are forcibly passed through the spout 103. In this way, the automatic sealing mechanism can be attached to the spout 103, and both sides of the sealing ring 5 contact the kettle body 101 and the connecting ring 16, respectively. A positioning block 162 is further provided on the side of the connecting ring 16 closest to the spout 102. Correspondingly, the sealing ring 5 is provided with a first positioning hole 51 that aligns with the positioning block 162, and the spout 103 of the kettle body 101 is also provided with a second positioning hole that aligns with the positioning block 162.
[0032] The automatic sealing mechanism further includes a spherical mesh cover 6, on the side of the connecting ring 16 away from the spout 102, there are multiple connecting parts 161, which are arranged at equal intervals in the circumferential direction of the connecting ring 16, and the spherical mesh cover 6 is connected to the connecting parts 161. The spherical mesh cover 6 encloses the gravity block 3 within the spherical mesh cover 6, thereby making the internal structure of the kettle body 101 more aesthetically pleasing and reducing interference between the water inside the kettle and the gravity block 3.
[0033] The present invention provides further protection for an electric kettle, comprising a kettle body 101, a spout 102, and a handle 104, wherein the spout 102 is located near the bottom of the kettle body 101, the handle 104 is located on the kettle body 101 opposite the spout 102, the kettle body 101 is provided with a water outlet 103, the water outlet 103 and the spout 102 are in communication, and the water outlet 103 is provided with the above-mentioned automatic sealing mechanism. <Example 2> Unlike Example 1, the recessed surface 1a does not have a water discharge hole 12 and a water intake hole 13, but only a through hole 10 is provided. Accordingly, the recessed surface 1a excluding the through hole is a solid structure without a perforated passage. The gap passage between the connecting rope 4 and the through hole 10 is large enough to satisfy the required water discharge flow rate at the spout 102.
