Abstract
Description
[Technical Field]
[0001] The present invention relates to the technical field of leakproofing of kettles, and in particular to an automatic sealing mechanism for a spout and an electric kettle fitted with said automatic sealing mechanism. [Background technology]
[0002] As household electric kettles become more widely used, the demand for safety in use is constantly increasing. For example, sealing structures such as sealing structures for the water inlet and sealing structures for the steam switch passage are adopted to prevent the kettles from tipping over.
[0003] Patent Document 1 (Chinese Utility Model No. 201379426) proposes a safety sealing device for an electric kettle that includes a leak-proof sealing structure between the spout, the kettle lid, and the spout, preventing water leakage even when the kettle body is rotated at any angle. In this utility model, the kettle body is provided with a spout corresponding to the spout, a valve seat for the spout, and an opening for the valve seat, which is connected to the leak-proof sealing structure. The spout-proof sealing structure includes an L-shaped spout valve that is attached to the valve seat by a spring and is movable up and down, with its lower end connected to the opening and its upper end connected to a valve-opening mechanism. The valve-opening mechanism includes a spout button, a link, and a lever. The lever is provided in the kettle lid, with one end connected to the upper end of the spout valve and the other end connected to the spout button by a link. The water discharge button is rotatably or slidably mounted on the inside or outside of the handle and connected to the rear end of a link. The link is mounted within the handle by a return elastic member, and its front end passes through the inside of the kettle body and is connected to a lever. The handle is mounted on the side of the kettle body, and a return spring is connected to the fulcrum of the lever.
[0004] In the above structure, the leak-proof sealing structure provided on the spout is always closed, and when pouring hot water, it is necessary to operate the water discharge button to open the water discharge passage of the spout, so automatic sealing or automatic opening is not realized. In addition, the water discharge button and the leak-proof sealing structure are connected by a link and a lever provided in the kettle lid, so the overall structure is complicated and the versatility of the leak-proof sealing structure is low.

[0005] [Patent Document 1] Chinese Utility Model No. 201379426 Summary of the Invention
[0006] The first technical problem that this invention aims to solve is to provide an automatic sealing mechanism for a spout that, in view of the current state of the prior art, can automatically adjust the opening and closing of the spout's water outlet passage depending on the state of the kettle itself, can be directly attached to the spout of a kettle, and is highly versatile.
[0007] The second technical problem that the present invention aims to solve is to provide an electric kettle equipped with the above-mentioned automatic sealing mechanism, in view of the current state of the prior art.
[0008] The technical solution used by the present invention to solve the first technical problem is as follows: The automatic sealing mechanism for a spout comprises a sealing part provided in a water discharge passage leading to the spout and sealing the water discharge passage, the sealing part having a through hole communicating with the water discharge passage at the center thereof, a recessed surface recessed from the outer periphery of the sealing part along the radial direction of the sealing part toward the outlet end of the through hole, the sealing part being located at the lowest point of the recessed surface, a plug movably provided on the side of the outlet end of the through hole in the sealing part for sealing the outlet end of the through hole, and a plug on the side of the inlet end of the through hole in the sealing part that runs smoothly along the recessed surface. The kettle includes a gravity block that is movably mounted on the recessed surface, and a connecting rope that passes through the through hole so that there is a gap passage between the through hole and the gravity block, and both ends of the connecting rope are connected to the plug and the gravity block, respectively.When the kettle is in an upright or inverted position, the gravity block hangs down, causing the plug to seal the outlet end of the through hole and close the water discharge passage leading to the spout.When the kettle is in a hot water supply position, 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 leading to the spout.
[0009] Preferably, a retaining ring extends outward from the outside of the sealing portion, and the inner peripheral wall of the retaining ring is in close contact with the outer peripheral wall of the plug when the kettle is in an upright or overturned position. By using the above technical solution, the inner peripheral wall of the retaining ring is in close contact with the outer peripheral wall of the plug, making it difficult for water in the kettle to leak out through the gap between the plug and the sealing portion, and improving the sealing effect of the plug on the water discharge passage.
[0010] Preferably, the plug has a truncated cone shape with a larger outer end and a smaller inner end, and the inner peripheral wall of the retaining ring and the outer peripheral wall of the plug engage to guide and seal. Because the plug is truncated cone shaped and the space enclosed by the inner peripheral wall of the retaining ring is also truncated cone shaped, when the kettle body is placed upright after hot water is dispensed, the plug moves in the axial direction of the retaining ring, and the truncated cone shapes of the plug and retaining ring perform a guiding function.
[0011] Preferably, the thickness of the retaining ring in the axial direction of the plug is greater than the thickness of the gravity block. By using the above technical solution, the gravity block is restricted by the retaining ring during the hot water supply process, so that the gravity block does not come out of the internal space of the retaining ring. After the hot water supply is finished, when the kettle body is placed upright, the gravity block easily re-engages with the retaining ring to form a tight seal.
[0012] Preferably, the retaining ring has a plurality of water discharge grooves arranged in the axial direction of the retaining ring, the water discharge grooves being spaced apart from one another. When the kettle is in a hot water supply state, there is a gap between the outer peripheral wall of the plug and the inner peripheral wall of the retaining ring. By using this technical solution, water in the kettle flows out through the gaps and then out of 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 a plurality of outlet holes for allowing water to flow out of the kettle, the outlet holes being spaced apart and surrounding the through-hole, and when the kettle is in an upright or inverted position, the gravity block droops and the plug seals the outlet holes, increasing the flow rate of water from the kettle.
[0014] Preferably, the recessed surface is provided with a plurality of water intake holes, the water intake holes being spaced apart and surrounding the through-hole, and the water intake holes being in communication with the water discharge hole. Similarly, the provision of the water intake holes increases the speed at which water is discharged from the kettle.
[0015] Preferably, a plurality of first stop ribs extend inward inside the sealing portion, the first stop ribs are arranged along the radial direction of the sealing portion, the first stop ribs are connected to each other near the center of the sealing portion to form the through hole, and the gaps between adjacent first stop ribs are the water intake holes. The height of each first stop rib near the center of the sealing portion is lower than the height of each first stop rib at the edge of the sealing portion, and the surface of each stop rib forms a recessed surface having the water discharge hole. The provision of stop ribs makes it possible to reduce the amount of material used, lower costs, and increase the diameter of the water intake holes.
[0016] Preferably, a second stop rib extends inward inside the sealing portion, the second stop rib being arranged along the radial direction of the sealing portion, the second stop rib being located between adjacent first stop ribs, and a gap being provided between one end of the second stop rib close to the through hole and the through hole. The additionally installed second stop rib is intended to prevent the gravity block from falling into the gap between adjacent first stop ribs. Furthermore, by providing a gap between the second stop rib and the through hole, the flow rate at the water intake hole can be increased.
[0017] Preferably, the sealing portion has an outer peripheral wall provided with a connecting ring extending radially outward, a sealing ring on the side of the connecting ring closer to the spout, and a plurality of buckles extending radially outward on the outer peripheral wall of the sealing portion, the buckles being equally spaced around the periphery of the sealing portion. The sealing ring is disposed 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 abuts between the kettle body and the connecting ring.
[0018] Preferably, the automatic mold sealing mechanism further includes a spherical mesh cover, and a plurality of connection portions are provided on the side of the connecting ring away from the spout, the plurality of connection portions being equally spaced around the circumference of the connecting ring, and the spherical mesh cover is connected to the connection portions.
[0019] Another technical solution used in the present invention to solve the first technical problem is as follows: The automatic sealing mechanism for a spout is an automatic sealing mechanism for a spout that is provided in a water discharge passage that leads to the spout, and comprises a sealing part that is provided in the water discharge passage and seals the water discharge passage, the sealing part having a central through-hole and a water intake hole that communicates with the water discharge passage, and a recessed surface that recesses from the outer periphery of the sealing part along the radial direction of the sealing part toward the water discharge end of the water intake hole on the side of the sealing part where the water intake end of the water intake hole is located, the through-hole being located at the lowest point of the recessed surface, a plug that is movably provided on the sealing part on the side of the water discharge end of the water intake hole for sealing the water discharge end of the water intake hole, and the kettle includes a gravity block that is arranged near the inlet end of the suction hole and is able to move smoothly along the recessed surface, and a connecting rope that passes through the through hole and is connected at both ends 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 suction hole and close the water discharge passage leading to the spout; when the kettle is in a hot water dispensing state, 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 suction hole, opening the suction hole and the water discharge passage leading to the spout. In this embodiment, there is no gap between the connecting rope and the through hole, and water flows only through the suction hole.
[0020] The technical solution used in the present invention to solve the second technical problem is as follows: An electric kettle includes a kettle body and a spout, the kettle body is provided with a water outlet that communicates with the spout, and the water outlet is provided with the automatic sealing mechanism.
[0021] Compared with the prior art, the present invention has the following advantages. When the kettle is tilted at a certain angle to dispense hot water, the gravity block slides along the recessed surface to its lowest point, causing the water flow to open the plug, allowing the water in the kettle to flow out. When the kettle is upright or inverted, the gravity block sags, causing the plug to seal the through-hole and close the spout's water outlet. The automatic sealing mechanism of the present invention can automatically open and close the water outlet depending on the state of the kettle itself, improving usability. Furthermore, because the automatic sealing mechanism of the present invention is directly attached to the kettle's spout, it is highly versatile and can be easily replaced if damaged.

DETAILED DESCRIPTION OF THE INVENTION
[0023] The present invention will now be described in more detail with reference to the accompanying drawings and examples. Example 1 1 to 6 show a preferred embodiment of an automatic sealing mechanism for a spout 102 of the present invention. 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 that runs from the interior space of the kettle 100 to the spout 102. In this embodiment, the automatic sealing mechanism is provided at the connection position between the spout 102 and the kettle body 101, i.e., at the water discharge port 103 in the kettle body 101, at the inlet of the spout 102. In other embodiments, the automatic sealing mechanism may be provided inside the spout 102.
[0025] As shown in FIGS. 2 to 6, the sealing portion 1 has a substantially cylindrical shape, and the outer peripheral wall of the sealing portion 1 is connected to a water outlet 103 in a kettle body 101 of a 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 a water discharge passage 102a. A plurality of first retaining ribs 14 extend in the axial direction on the side surface of the sealing portion 1 facing the inside of the kettle body 101, and each of the first retaining ribs 14 is provided along the radial direction of the sealing portion 1. The first retaining ribs 14 are connected to each other at 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 of the first retaining ribs 14 is formed radially extending in the radial direction of the sealing portion 1, centered on the through-hole 10. A plurality of second stop ribs 15 also extend axially on the side of the sealing portion 1 facing the inside of the kettle body 101, and each second stop rib 15 is arranged along the radial direction of the sealing portion 1, and the second stop ribs 15 and the first stop ribs 14 are arranged alternately at intervals, and there is a gap between one end of the second stop rib 15 near the through hole 10 and the through hole 10. As shown in Figures 3 and 6, both the first stop rib 14 and the second stop rib 15 are arranged along the radial direction of the side surface of the sealing portion 1, and the height of the first stop rib 14 and the second stop rib 15 gradually decreases along the radial direction toward the outlet end 10b of the through hole 10 (they are recessed toward the center).The first stop rib 14 and the second stop rib 15 form a single recessed surface 1a on the side surface of the sealing portion 1, and the recessed surface 1a gradually slopes along the radial direction of the sealing portion 1 toward the outlet end 10b of the through hole 10, and the lowest point of the recessed surface 1a is at the position where the through hole 10 is located.
[0026] As shown in Figure 4, a plurality of water outlet holes 12 for allowing water to flow out of the kettle 100 are provided on the side of the sealing part 1 facing away from the interior of the kettle body 101. The water outlet holes 12 are spaced apart and surround the through-hole 10. In this embodiment, the water outlet holes 12 are also formed by gaps between adjacent first retaining ribs 14. In other words, the water outlet holes 12 are an extension of the water intake hole 13. A retaining ring 11 extends axially on the side of the sealing part 1 facing away from the interior of the kettle body 101. The retaining ring 11 and the through-hole 10 are concentric and the retaining ring 11 surrounds the outside of the water outlet 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 portion 1, i.e., the side of the discharge end 13b of the water inlet 13. The gravity block 3 is mounted on the side of the inlet end 10a of the through-hole 10 in the sealing portion 1, i.e., the side of the water inlet end 13a of the water inlet 13, so that it can move smoothly along the recessed surface 1a. 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 in the spout 102, and the gravity block 3 is located in the kettle body 101. Between the connecting rope 4 and the through-hole 10, there may be a larger gap for water to pass through, or there may be a smaller gap that only allows the connecting rope 4 to move. In the former case, if there is a large gap, water can pass through the gap and the water inlet 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 accidentally tipped over, the gravity block 3 sags (hangs downward), causing the inner circumferential wall of the retaining ring 11 to tightly contact the outer circumferential wall of the plug 2, sealing the through hole 10 and the water discharge hole 12. When the kettle 100 is in the correct hot water supply position, 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 discharge end 13b of the water inlet hole 13, the plug 2 moves away from the outlet end 10b of the through hole 10 and the discharge end 13b of the water inlet hole 13, and the water in the kettle flows out through the gap between the plug 2 and the retaining ring 11. Conversely, after hot water has been dispensed, the connecting rope 4 moves laterally together with the gravity block 3 toward one side of the inlet end 13a of the inlet hole 13, and the plug 2 moves accordingly to seal the through hole 10 and the inlet hole 13. The upright or inverted position of the kettle 100 means that the kettle is not dispensing hot water. The angle of inclination in the hot water dispensing state is such that the through hole 10 is positioned at the lowest point of the recessed surface 1a in the direction of gravity. When dispensing hot water, the gravity block 3 moves smoothly along the recessed surface 1a.
[0029] Furthermore, retaining ring 11 is provided with a plurality of water discharge grooves 111 along the axial direction of retaining ring 11, and water discharge grooves 111 are provided at intervals from one another. After water inside kettle body 101 flows out from the gap between plug 2 and retaining ring 11, it can quickly flow out of said water discharge grooves 111.
[0030] The plug 2 has a truncated cone shape, and the diameter of the outer end face of the plug 2 is larger than the diameter of the inner end face of the plug 2. The diameter of the inner peripheral wall of the retaining ring 11 is also set to match the plug 2.
[0031] To facilitate connection of the automatic sealing mechanism to the kettle, a connecting ring 16 extends radially outward from the outer peripheral wall of the sealing portion 1, a sealing ring 5 is provided on the side of the connecting ring 16 closer to the spout 102, and a plurality of buckles 17 extend radially outward from the outer peripheral wall of the sealing portion 1, the buckles 17 being equally spaced around the periphery of the sealing portion 1, and the sealing ring 5 being disposed between the connecting ring 16 and the buckles 17. In the process of installing the automatic sealing mechanism, the automatic sealing mechanism is inserted into 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 installed on the spout 103, with both sides of the sealing ring 5 abutting against 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 closer to the spout 102, and correspondingly, a first positioning hole 51 aligned with the positioning block 162 is provided in the sealing ring 5, and a second positioning hole aligned with the positioning block 162 is also provided in the spout 103 of the kettle body 101.
[0032] The automatic sealing mechanism further includes a spherical mesh cover 6, and a plurality of connection portions 161 are provided on the side of the connecting ring 16 away from the spout 102, the connection portions 161 being equally spaced around the circumference of the connecting ring 16, and the spherical mesh cover 6 is connected to the connection portions 161. The spherical mesh cover 6 encloses the gravity block 3 within the spherical mesh cover 6, which makes the internal structure of the kettle body 101 more aesthetically pleasing and also reduces interference with the gravity block 3 by the water in the kettle.
[0033] The present invention further seeks protection for an electric kettle that includes a kettle body 101, a spout 102, and a handle 104, the spout 102 being located at a lower position on the kettle body 101, the handle 104 being located on the kettle body 101 opposite the spout 102, the kettle body 101 being provided with a water outlet 103 that is connected to the spout 102, and the water outlet 103 being provided with the above-mentioned automatic sealing mechanism. <Example 2> Unlike Example 1, the recessed surface 1a does not have the water discharge hole 12 or the water intake hole 13, but only the through hole 10. Accordingly, the recessed surface 1a excluding the through hole is a solid structure without a hole passage. The gap passage existing between the connecting rope 4 and the through hole 10 is large enough to meet the water discharge flow rate requirements at the spout 102.
