Description

[Technical Field]

[0001] The present invention relates to the technical field of electric kettle products, and more particularly to a lid for an electric kettle with an anti-tip function. [Background technology]

[0002] An electric kettle is a common household appliance that converts electricity into heat to heat water to a desired temperature. Its main components are a heating element, a temperature control device, a cavity, and a water outlet. Electric kettles are widely used in homes, offices, etc. because of their high efficiency, convenience, and quick boiling of water.

[0003] A Chinese invention publication (application number 202323172383.4) discloses a tip-prevention kettle lid structure. It includes a lid and a kettle body. The lid is equipped with an operating component, a passageway, and a sealing plate. The lid covers the mouth of the kettle body, connecting the lower end of the passageway to the inner cavity of the body, with the upper end of the passageway facing the spout of the body. The operating component is power-transmittingly connected to the sealing plate, engaging the sealing plate with the lower end of the passageway. A floating weight is provided on the operating component or the sealing plate. When the body is abnormally tilted, gravity acting on the floating weight is still vertically downward, but this gravity no longer acts on the operating component or the sealing plate. Therefore, the driving force generated by the operating component causes the sealing plate to close the lower end of the passageway, thereby preventing tip-over. The overall structure is compact and streamlined, effectively improving the user experience of the kettle product.

[0004] The above-mentioned anti-tip lid structure does not have a drainage function, which causes the problem of water accumulation. That is, water tends to accumulate inside the lid during heating or washing processes and is difficult to drain. This residual water can cause impurities such as bacterial growth and mineral precipitation inside the lid after repeated or prolonged use, which can affect human health and cause great inconvenience to users.

[0005] In view of this, the present inventor proposes the following technical solution. Summary of the Invention [Problem to be solved by the invention]

[Figure 5] FIG. 2 is a partial enlarged view of part A in FIG. [Figure 6] FIG. 2 is a cross-sectional view of another embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0019] The present invention will be further described below with reference to specific embodiments and drawings.

[0020] 1 to 5, the tip-over-proof electric kettle lid is for use with an electric kettle and is separable from the kettle body. The tip-over-proof electric kettle lid includes a lid body 1, a water outlet valve 2, a steam valve 3, and an operating mechanism 4.

[0021] The cover 1 has a water outlet 101 and a steam discharge passage 102, and the cover 1 is provided with a spout 103 that communicates with the water outlet 101; the water outlet valve 2 is slidably attached to the cover 1 and is used to close or open the water outlet 101; the steam valve 3 includes a valve chamber 31 that is provided in the cover 1 and communicates with the steam discharge passage 102, and a valve ball 32 that is movably attached in the valve chamber 31 and can close the steam discharge passage 102 when the cover 1 is tilted, the valve ball 32 being made of stainless steel. Under normal conditions, a gap is formed between the valve ball 32 and the inner wall of the valve chamber 31; the operating mechanism 4 is attached inside the cover 1 and slides the water outlet valve 2 to open or close the water outlet 101, and the actuator 41 of the operating mechanism 4 is exposed to the outside of the cover 1; a drain chamber 11 is further provided inside the cover 1, and a drain outlet 111 is formed at the bottom of the drain chamber 11, penetrating the lower end surface or side surface of the cover 1, and this drain outlet 111 is blocked by a removable drain plug 12.

[0022] When the tip-over-proof electric kettle lid is attached to the electric kettle body, in its initial state, the water outlet valve 2 closes the water outlet 101, and a gap is formed between the valve ball 32 and the inner wall of the valve chamber 31, i.e., the steam valve 3 is open. When the electric kettle is powered on and the water inside boils, the generated steam is discharged through the steam exhaust passage 102, preventing any unforeseen pressure buildup inside the electric kettle. If the electric kettle tips over, the valve ball 32 in the steam valve 3 moves within the valve chamber 31 to block the steam exhaust passage 102, i.e., the steam exhaust passage 102 is closed. At this time, water in the electric kettle cannot flow out through the steam exhaust passage 102 or the water outlet 101, thereby preventing water leakage in the event of tipping over. When water needs to be poured from the electric kettle, the actuator 41 is pressed to slide the water outlet valve 2, thereby opening the water outlet 101 and allowing the water in the electric kettle to be poured through the water outlet 101 and the pouring spout 103, thereby satisfying usage requirements. Furthermore, even if water accumulates inside the lid 1 during use or cleaning, this water collects in the drain chamber 11. When drainage is required later, simply by pulling the drain plug 12 directly out of the drain outlet 111, the accumulated water in the drain chamber 11 can be easily drained through the drain outlet 111. This prevents the accumulation of water inside the lid, which can lead to bacterial growth and mineral deposits, thereby preventing adverse health effects and achieving the drainage function. This also makes the lid easier to clean, making it more hygienic. In this embodiment, the bottom surface of the drain chamber 11 slopes downward toward the drain outlet 111. This allows all the water in the drain chamber 11 to flow downward toward the drain outlet 111, allowing the accumulated water in the drain chamber 11 to be completely discharged from the drain outlet 111 at a later stage, preventing water from accumulating inside the lid 1 and avoiding the health effects caused by bacterial growth.

[0023] The drain chamber 11 includes a peripheral drainage channel 112 provided around the periphery of the lumen of the lid 1 and a central drainage channel 113 provided at or near the center of the lumen of the lid 1. The peripheral drainage channel 112 is connected to the central drainage channel 113 via a confluence port 114. The drainage port 111 is provided at the bottom of the central drainage channel 113. The design of the peripheral drainage channel 112 and the central drainage channel 113 allows water that has entered the lid 1 through various gaps to be collected and combined, making drainage smoother and cleaner and contributing to subsequent drainage. The bottom of the peripheral drainage channel 112 slopes downward toward the confluence port 114, allowing water that flows into the peripheral drainage channel 112 to flow toward the confluence port 114, flow through the confluence port 114 to the central drainage channel 113, and then be easily discharged from the drainage port 111 provided at the bottom of the central drainage channel 113.

[0024] It is worth noting that the portion of the actuator 41 of the operating mechanism 4 that penetrates the outer wall of the lid 1 and is exposed to the outside of the lid 1 can create a gap between the lid 1 and the actuator, which can allow water to flow into the inside of the lid 1 when the lid is washed. However, in the present application, the operating mechanism 4 and its actuator 41 are positioned above the central drainage channel 113, so that water that enters the inside of the lid 1 during washing flows into the central drainage channel 113 and collects in the drain outlet 111. This makes it easier to drain the water in the subsequent stages.

[0025] In this embodiment, drain plug 12 is a rubber or silicone plug, and includes a fitting portion 121 and a pressing portion 122 extending outward from the lower periphery of fitting portion 121. Fitting portion 121 is fitted into drain outlet 111 and is tightly fitted by an over-fit (tight fit) to seal drain outlet 111, providing an excellent sealing effect and making it easy to pull out to open drain outlet 111 later.

[0026] In some other embodiments, an annular groove 124 is formed on the outer periphery of fitting portion 121, and fitting portion 121 is engaged and held by annular groove 124 and rib 115 formed on the inner wall of drain outlet 111. This not only improves the sealing performance between fitting portion 121 and drain outlet 111, but also improves the stability between fitting portion 121 and drain outlet 111, effectively preventing drain plug 12 from accidentally coming off drain outlet 111.

[0027] In yet another embodiment, the vertical cross section of drain plug 12 is "box" shaped, i.e., fitting portion 121 has grooves 123 formed from its lower end upward to reduce material usage and improve elasticity. The bottom of grooves 123 is located higher than annular groove 124, which allows fitting portion 121 to deform better and allows annular groove 124 to be more smoothly engaged and held with rib 115, improving assembly efficiency. The structure of the lid 1 will now be described in detail.

[0028] The lid body 1 includes a lid body 13, a bottom lid 15 attached to the lower end of the lid body 13 via a seal gasket 14, and a top lid 16 attached to the upper end of the lid body 13. The operating mechanism 4 is attached inside the lid body 13, and a part of the actuator 41 passes through a window provided on the outside of the top lid 16 and protrudes outside the lid body 1, so that the operating mechanism 4 can be controlled and operated by being pressed by hand at a later stage.

[0029] In this embodiment, the spout 103 is attached between the lid body 13, the top lid 16, and the bottom lid 15 via a seal frame 17, and the bottom lid 15 is provided with the water outlet 101. The spout 103 and the bottom lid 15 are both made of stainless steel. Of course, higher quality materials may also be used. The spout 103 is provided with a water outlet passage that communicates with the water outlet 101.

[0030] The piston shaft 22 of the water outlet valve 2 passes through the seal frame 17 in a sealed manner and is slidable therethrough, and the two are hermetically assembled. Even when the piston shaft 22 slides relative to the seal frame 17, there is no risk of water leakage.

[0031] The drain port 111 is provided at the bottom end of the lid body 13, and a drain chamber 150 is also provided between the lid body 13 and the bottom cover 15. The bottom cover 15 has a drain hole 151 communicating with the drain chamber 150 at a position corresponding to the drain port 111, and an annular protrusion 152 is provided around the drain hole 151. A drain gap is formed between the inner edge of the drain hole 151 and the outer edge of the drain port 111. The drain plug 12 has a sealing groove 125, and the drain plug 12 is sealed to the annular protrusion 152 via the sealing groove 125. This assembly structure is stable and seals the drain gap, resulting in a better sealing effect. When the drain plug 12 is pulled out of the drain port 111, the drain hole 151 also opens, allowing accumulated water in the drain chamber 150 to be drained through the drain hole 151, further improving the drainage function of the present invention. The sealing groove 125 is provided on the upper end surface of the pressing portion 122.

[0032] The bottom cover 15 is provided with steam holes 153 that communicate with the valve chamber 31, and a support protrusion 154 located between the steam holes 153. In other words, the steam holes 153 are part / the entrance to the steam discharge passage 102. The support protrusion 154 protrudes from below to above into the valve chamber 31, supports the valve ball 32, and ensures that a gap is always maintained between the valve ball 32 and the steam holes 153.

[0033] The structure of the water outlet valve 2 will be specifically described below.

[0034] The water outlet valve 2 includes a piston 21, a piston shaft 22 provided on the piston 21, and a piston seal ring 23 provided on the piston 21. The upper end of the piston shaft 22 is connected to the operating mechanism 4 and is controlled by the operating mechanism 4 to achieve up and down movement. The piston 21 abuts against the bottom surface of the lid 1 via the piston seal ring 23, sealing the water outlet 101. The piston shaft 22 is provided to pass through the seal frame 17 and is movable relative to the seal frame 17.

[0035] The piston seal ring 23 has a covering structure and encases the outer edge, side, and upper end surface of the lower end surface of the piston 21. A steam discharge gap 201 is formed between the upper inner wall of the piston seal ring 23 and the upper surface of the piston 21, and a discharge gap 202 communicating with the steam discharge gap 201 is formed between the piston seal ring 23 and the outer surface of the piston shaft 22. The piston 21 has a plurality of steam discharge holes 211 extending upward from its lower end surface, and the steam discharge holes 211, steam discharge gap 201, and discharge gap 202 are sequentially connected to form a steam discharge capillary passage. The steam discharge capillary passage, together with the steam discharge passage 102, forms a double steam passage, improving the exhaust effect. Specifically, the dimensions of the steam discharge capillary passage are much smaller than those of the steam discharge passage 102, making the steam discharge passage 102 the primary exhaust passage. Only when the steam exhaust passage 102 fails to exhaust properly due to various factors does pressure build up inside the electric kettle, and the steam exhaust capillary passage functions. The pressurized steam expands and enlarges the steam exhaust gap 201 formed between the upper inner wall of the piston seal ring 23 and the top surface of the piston 21, allowing the steam to be exhausted through the steam exhaust capillary passage and then through the spout to the outside of the lid. If the electric kettle falls over, the valve ball 32 moves within the valve chamber 31, blocking the steam exhaust passage 102 and preventing water from escaping through the passage 102. Because the steam exhaust capillary passage is small in diameter, the water inside the kettle does not flow out through the capillary passage.

[0036] In some embodiments, the bottom surface of the cover 1 is provided with a receiving groove 104, and the water outlet 101 is formed on the bottom surface of the receiving groove 104. A plurality of sealing ribs 231 are provided at intervals on the upper surface of the piston seal ring 23, and the piston seal ring 23 is press-fitted into the receiving groove 104 from below, thereby improving the assembly stability. The sealing ribs 231 abut against the bottom surface of the receiving groove 104 to form a sealed assembly, thereby improving the sealing effect.

[0037] The structure of the operating mechanism 4 will now be described in detail.

[0038] The actuating mechanism 4 includes a return link 42 and an actuator 41 .

[0039] Specifically, one end of the return link 42 is connected to the water outlet valve 2, and the other end is rotatably connected to the cover 1. A movable hole 421 is provided in the middle of the return link 42 or a position nearby, and this movable hole 421 allows the return link 42 to be fitted onto a guide post 18 inside the cover 1, allowing it to slide up and down. A return spring 6 is attached to the outer periphery of the guide post 18, and its elasticity presses against the return link 42, providing elastic support and urging the water outlet valve 2 in the direction of closing the water outlet 101. Furthermore, a screw 19 is provided at the upper end of the guide post 18, and the head of the screw 19 protrudes outward from the upper end surface of the guide post 18 to prevent the return link 42 from coming off the guide post 18.

[0040] One end of the actuator 41 is rotatably connected to the cover 1, and the other end protrudes outside the cover 1 as a button 411. A pressing protrusion 412 is provided at the lower end of the actuator 41, and the pressing protrusion 412 abuts against the center of the return link 42 or a position nearby. When the button 411 is pressed, the pressing protrusion 412 presses the return link 42 downward, moving one end of the return link 42 and the water outlet valve 2 downward against the elastic force of the return spring 6 and opening the water outlet 101.

[0041] In this embodiment, referring to FIG. 1 , the steam exhaust passage 102 is connected to the spout 103, and steam entering the steam exhaust passage 102 is directed to the spout 103 and then discharged to the outside. In other embodiments, referring to FIG. 6 , the steam exhaust passage 102 is connected to the outer surface of the lid 1, and a sealing nozzle 100 is provided on the outer surface of the lid 1. After the lid 1 is attached to the electric kettle body, the sealing nozzle 100 abuts against the steam inlet on the inner wall of the body. The handle of the body is provided with a pipe connected to the steam inlet, which is connected to the bottom of the body and corresponds to a steam detection switch provided on the bottom of the body. In this way, after steam is discharged from the steam exhaust passage 102 in a later stage, it is directed to the bottom of the body via the steam inlet on the inner wall of the body and the pipe. When the steam detection switch detects steam, the electric kettle can be powered off and heating can be stopped.

[0042] As described above, the present invention not only prevents water leakage due to tipping over, but also has a drainage function, allowing stagnant water inside the lid to be easily drained, preventing bacterial growth and adverse effects on human health.
