Description

[Technical field]

[0001] The present invention relates to the technical field of electric kettles, and more particularly to a structure for preventing an electric kettle from tipping over and spilling hot water. [Background technology]

[0002] Many of the important spill prevention structures of leak-proof kettles currently on the market use weights or steel balls to simply stop the water flow, and when the kettle is tilted or tipped over, a lot of hot water leaks out, so it is not a kettle that truly prevents spills (dripping).

[0003] Patent Document 1 discloses a rotatable water-running prevention structure, in which any steam discharge hole in the technology is combined with a notch to form a steam discharge path, which can discharge hot steam from the kettle body, and when the kettle body is tilted in any direction, the rotating plate assembly moves its center of gravity to a lower position, and the steam discharge hole combined with the notch is at a higher position, which prevents the rotating plate assembly from blocking other steam outlets and preventing hot water from flowing out of the steam discharge path. However, the prior art still has defects, such as the diameter of the pendulum in the prior art only occupies about half of the lid, and there are vents evenly arranged around the pendulum, so when the kettle body falls over, if the hot water in the kettle exceeds the vents in the lid, a large amount of hot water will leak out from the vents, which cannot prevent dripping, and the silicone pendulum in the prior art needs to swing all around and seal all around, which is a design contradiction.

[0004] [Patent Document 1] Chinese Patent No. 202322523582.9 Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention has been made in consideration of the above circumstances, and provides a structure to prevent an electric kettle from tipping over and causing water to spill. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention employs the following technical means: A structure for preventing water from spilling when an electric kettle tips over, the electric kettle comprises a kettle body and a lid, an opening is formed at the top of the kettle body, a water storage space is formed inside the kettle body, the lid is attached to the opening, a handle is provided on the kettle body, a steam exhaust passage is provided within the handle, a steam passage is provided inside the lid, the steam passage has a steam inlet and a steam outlet, the steam inlet is connected to a steam intake hole of the lid, the steam outlet is connected to the steam exhaust passage of the handle, the steam passage comprises a first passage arranged in an annular shape, the first passage is arranged near the edge of the lid, and at least a part of the first passage is located above the liquid level when the electric kettle is tilted. This technology provides an annular steam passage in the lid, so that when the kettle body is tilted when the water storage space is at the rated capacity, the water in the kettle body covers only half of the lid, and because the first passage in the steam passage is provided in an annular shape and positioned near the edge of the lid, at least a portion of the first passage can be positioned above the liquid level, and water in the kettle body cannot enter the steam exhaust path from the steam outlet, thereby achieving the objective of preventing hot water spilling and dripping.

[0007] In a preferred embodiment of the present invention, a leak-proof chamber is provided in the lid, which connects the steam outlet of the steam passage and the steam exhaust passage of the handle. A sealing member and an elastic member are provided in the leak-proof chamber. When the electric kettle is placed upright, the steam passage, the leak-proof chamber and the steam exhaust passage are connected. When the electric kettle is tilted or upside down, the sealing member blocks the steam passage, the leak-proof chamber and the steam exhaust passage. Since the sealing member and the elastic member are provided in the leak-proof chamber, the situation in which the sealing member does not block the hole when the electric kettle is tilted at a small angle is eliminated, thereby realizing the function of preventing hot water from spilling and dripping. When the electric kettle is upside down (i.e., the lid is facing downward and the bottom of the kettle body is facing upward), the entire steam passage is below the water level, but the hole is blocked by the sealing member, thereby realizing the function of preventing hot water from spilling and dripping.

[0008] As a preferred embodiment of the present invention, the lid body includes an upper shell, a partition wall, a middle shell and a steam cover assembled in order from top to bottom, and the steam cover is provided with the steam intake hole.

[0009] As a preferred embodiment of the present invention, a steam passage seal ring is provided between the steam cover and the inner shell, The steam passage is defined by the steam cover and the steam passage seal ring, the steam passage being arranged in an annular shape near the edge of the steam cover, with a steam inlet provided in the steam cover and a steam outlet provided in the steam passage seal ring; in this technology, the steam passage is defined by the steam cover and the steam passage seal ring, the processing of the steam cover is simple, and after processing an open-upward groove body on the steam cover, the steam passage seal ring can seal the upward opening of the groove body to define the steam passage, and the steam passage seal ring performs a sealing action, so that steam can only flow out from the steam outlet provided in the steam passage seal ring and prevents steam from flowing into other positions of the cover.

[0010] In a preferred embodiment of the present invention, the steam intake hole is disposed within a surrounding range of the steam passage, and a plurality of steam intake holes are disposed, so that steam flows into the steam passage through the steam intake holes.

[0011] As a preferred means of the present invention, the middle shell is provided with an annular rib extending upward and perpendicular to the bottom surface, and the partition wall is molded with a sleeve extending downward and inserted into the space defined by the annular rib, the lower end of the sleeve is connected to the steam outlet, a hole is formed at the upper end of the sleeve, and a sealing member and an elastic member are installed in the sleeve. The present technology defines the structure of the middle shell and the partition wall, and the upper shell, the partition wall, the middle shell and the steam cover are assembled to form a leak-proof chamber, and the space inside the sleeve is a part of the leak-proof chamber.

[0012] In a preferred embodiment of the present invention, a steam discharge hole is provided on the side of the inner shell, steam flows from the hole to the steam discharge hole, and a steam joint is provided at the steam discharge hole, which is connected to the steam exhaust passage of the handle through the steam joint.

[0013] As a preferred embodiment of the present invention, the handle is provided with a switch, which may be a temperature control switch, and when the steam temperature reaches a set value, the switch is turned off to stop heating the electric kettle.

[0014] As a preferred embodiment of the present invention, a pouring button assembly is also provided in the cover, which can control the opening and closing of the pouring spout of the electric kettle.

[0015] The remaining advantageous technical effects of the present invention are reflected in specific embodiments.

[Figure 6] FIG. 5 is an enlarged view of a portion A in FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] The present invention will be described in more detail below with reference to the accompanying drawings, which are simplified schematic diagrams showing the basic structure of the present invention, and show only the components related to the present invention.

[0019] This is a structure to prevent hot water from spilling when an electric kettle tips over. Referring to Figures 1 to 6, the electric kettle comprises a kettle body 100 and a lid. An opening 101 is formed at the top of the kettle body 100. A water storage space 102 is formed inside the kettle body 100. A lid 200 is attached to the opening 101. A handle 300 is provided on the kettle body 100. A steam exhaust passage 301 is provided within the handle 300. As shown in Figure 1, the electric kettle of this embodiment also comprises a base 00. The kettle body 100 is placed on the base 00 and heated by passing electricity through it.

[0020] Alternatively, the base 00 may be omitted, and the base and the kettle body may be designed as an integral structure, and a heating member may be provided at the bottom of the kettle body 100 to heat the water storage space 102 .

[0021] In addition, a steam passage 400 is provided inside the lid body 200, the steam passage 400 having a steam inlet 410 and a steam outlet 420, the steam inlet 410 communicating with the steam intake hole 210 of the lid body 200, the steam outlet 420 communicating with the steam exhaust passage 301 of the handle 300, the steam passage 400 having a first passage 401 arranged in an annular shape, the first passage 401 being arranged near the edge of the lid body 200, when the electric kettle is tilted, at least a part of the first passage 401 being located above the liquid level, 2 and 3, the cross section of the cover 200 is substantially annular, and the steam passage 400 is provided inside the cover 200. The steam passage 400 may be a passage arrangement of one circle, or a passage arrangement of several circles distributed concentrically, and the passages of several circles are connected in sequence, When the steam passage 400 is arranged in a circumferential direction, the first passage 401 constitutes the steam passage 400, When the steam passages 400 are arranged in several turns, the outermost passage is the first passage 401 .

[0022] In this embodiment, as shown in Figures 2 and 3, when the steam passage 400 goes around in a ring shape, the first passage 401 corresponds to the steam passage 400, and steam enters through the steam intake hole 201 of the cover body 200, enters the steam passage 400 from the steam inlet 410, flows around the steam passage 400, and then flows out from the steam outlet 420 to the steam exhaust path 301.

[0023] In the case of rated capacity, i.e., under the maximum capacity set for the water storage space, when the electric kettle is tilted, the water level in the water storage space 102 only exceeds more than half of the lid body 200. Even if the water level exceeds most of the lid body 200 as shown in FIG. 5, part of the steam passage 400 is above the liquid level, and the water cannot flow upward against gravity and therefore does not flow out through the steam passage 400, thereby preventing hot water from spilling and dripping.

[0024] In one embodiment, as shown in FIG. 4 and FIG. 6, a leak-proof chamber 500 is provided in the cover 200, and the leak-proof chamber 500 connects the steam outlet 420 of the steam passage 400 and the steam exhaust passage 301 of the handle 300. A sealing member 510 and an elastic member 520 are provided in the leak-proof chamber 500. When the electric kettle is placed upright, the steam passage 400, the leak-proof chamber 500, and the steam exhaust passage 301 communicate with each other. When the electric kettle is tilted or upside down, the sealing member 510 blocks the steam passage 400, the leak-proof chamber 500, and the steam exhaust passage 301. Specifically, as shown in FIG. 4 and FIG. 6, the sealing member 510 is a steel ball, the elastic member 520 is a spring, the steel ball is attached to the top of the spring, and there is a gap between the steel ball and the side wall of the leak-proof chamber 500. When the electric kettle is placed upright, the gravity of the steel ball acts on the spring, compressing the spring, and the hole 202 above the steel ball opens, and steam enters the steam intake hole 201 and the steam inlet 410 into the steam passage 400. After flowing around the steam passage 400, the steam enters the leak-proof chamber 500 through the steam outlet 420, and then flows upwards through the hole 202, and finally flows into the steam exhaust passage 301 of the handle 300. As shown in FIG. 5, when the electric kettle is tilted at about 90°, the elastic force of the spring presses the steel ball against the hole 202, blocking the hole 202. As a result, steam remains in the leak-proof chamber 500 and cannot flow into the steam exhaust passage 301 via the hole 202. This prevents the hot water from spilling and the liquid from dripping.

[0025] In another situation, when the electric kettle is turned upside down by 180 degrees, that is, when the bottom of the kettle body 100 faces upward and the lid body 200 faces downward, the entire steam passage 400 is below the water surface, at this time, the steel ball is pushed by its own gravity and the elastic force of the spring to block the hole 202, and even if water enters the leak-proof chamber 500, it is blocked by the leak-proof chamber 500 and cannot flow into the steam exhaust path 301 via the hole 202, thereby preventing hot water from spilling and dripping.

[0026] In one embodiment, as shown in FIG. 3, the cover 200 includes an upper shell 210, a partition wall 220, a middle shell 230 and a steam cover 240, which are assembled from top to bottom, and the steam cover 240 is provided with a steam intake hole 201.

[0027] Continuing to refer to FIG. 3 , a steam passage seal ring 270 is provided between the steam cover 240 and the inner shell 230, the steam cover 240 and the steam passage seal ring 270 define a steam passage 400, the steam passage 400 is disposed annularly near the edge of the steam cover 240, a steam inlet 410 is provided in the steam cover 240, a steam outlet 420 is provided in the steam passage seal ring 270, and the steam intake hole 201 is disposed within the surrounding range of the steam passage 400.

[0028] Specifically, a groove having an opening facing upward is provided around the edge of the steam cover 240, and the steam passage seal ring 270 is disposed annularly and is blocked above the groove, so that the steam cover 240 and the steam passage seal ring 270 define the steam passage 400. Continuing to refer to FIG. 3, the steam passage 400 is arranged in a generally annular manner, with a steam inlet 410 located at a beginning end of the steam passage 400 and a steam outlet 420 at a corresponding end of the steam passage seal ring 270 to the steam passage 400, the steam inlet 410 and the steam outlet 420 being adjacent to each other.

[0029] Continuing to refer to FIG. 3, a radial partition plate 241 is provided between the beginning and end of the steam passage 400, which separates the beginning and end of the steam passage 400. The steam path is shown by the dashed line in FIG. 2. After entering the steam passage from the steam inlet 410, the steam can flow around the steam passage 400 and then flow out from the steam outlet 420. This ensures that when the electric kettle is tilted, only a portion of the steam is above the liquid level, thereby preventing the hot water from spilling and the liquid from dripping.

[0030] In one embodiment, as shown in FIG. 3, the middle shell portion 230 is provided with an annular rib 231 extending upward and perpendicular to the bottom surface, the partition wall 220 is formed with a sleeve 221 extending downward and inserted into the space defined by the annular rib 231, the lower end of the sleeve 221 is connected to the steam outlet 420, a hole 202 is formed at the upper end of the sleeve 221, a sealing member 510 and an elastic member 520 are installed in the sleeve 221, a steam discharge hole 230 is provided on the side of the middle shell portion 230, steam flows from the hole 202 to the steam discharge hole 203, a steam joint 250 is provided in the steam discharge hole 203, and the steam joint 250 is connected to the steam exhaust passage 301 of the handle 300.

[0031] Specifically, as shown in Figures 3 and 6, after assembly, the middle shell portion 230 is abutted against the steam passage seal ring 270, a hole is provided at a location corresponding to the steam outlet 420 within the surrounding range of the annular rib 231 of the middle shell portion 230, and after the partition wall 220 is attached to the middle shell portion 230, the sleeve 221 is inserted into the surrounding range of the annular rib 231, and the lower end of the sleeve 221, the hole, and the steam outlet 420 are sequentially connected.

[0032] As shown in FIG. 3, the partition wall 220 is also provided with a rib 222, the hole 202 is located within the space surrounded by the rib 222, and a hole A204 is also provided within the space surrounded by the rib 222. As shown in FIG. 6, the upper shell portion 210 is provided with a downward frame portion 211, which is fitted into the rib 222. After flowing out from the hole portion 202, the steam flows again into the space surrounded by the annular rib 231 via the hole portion A204, and then enters the steam joint 250 from the steam discharge hole 203 on the side, and finally flows into the steam discharge passage 301.

[0033] Finally, the steam path is as follows: water storage space → steam intake hole → steam inlet → steam passage → steam outlet → leak-proof chamber → hole → hole A → steam release hole → steam joint → steam exhaust passage.

[0034] In one embodiment, the handle 300 is provided with a switch 310, which may be a temperature control switch, and when the steam temperature reaches a threshold value, the temperature control switch is turned off to stop the electric kettle from heating; In this embodiment, as shown in FIG. 1, the switch 310 is provided at a position close to the steam joint 250 at the upper end of the handle 300. Alternatively, the switch 310 can be provided at the bottom end of the handle 300 or at the bottom of the kettle body 100.

[0035] In one embodiment, a pouring button assembly 260 is also provided in the cover 200, and the pouring button assembly 260 controls whether or not to pour water from the pouring spout of the kettle body 100. In this embodiment, the specific structure of the pouring button assembly 260 is not limited.
