Description

Technical Field

[0001] This utility model relates to the field of electric kettles, and in particular to an electric kettle with an anti-tipping structure. Background Technology

[0002] Electric kettles heat water by using a heating element. However, existing electric kettles have the following problems: 1. Generally, a steam vent is provided to prevent the lid from coming off due to high pressure. However, this structure also has the problem of the steam from the back scalding the hand near the handle when pouring water, which affects the user experience. Therefore, the existing design generally adopts a side-opening structure. 2. The spouts of most existing electric kettles are open-type, which reduces their heat retention performance. When a sealed structure is used, high-pressure splashing can easily occur when the kettle is tilted, leading to scalding.

[0003] For example, Chinese patent 202222438177.2 releases steam by pressing the operating block, which makes the structure relatively complex. However, it has limited application in terms of practicality and product aesthetics, thus affecting the promotion of the product. Utility Model Content

[0004] The main purpose of this utility model is to propose an electric kettle with an anti-tipping structure, which aims to achieve the sealing of the kettle spout. At the same time, when the kettle or steam overflows, the lid and body work together to guide the flow, improving the usability of the structure, enhancing the user experience, and thus improving market competitiveness.

[0005] To achieve the above objectives, this utility model proposes an electric kettle with an anti-tipping structure, comprising: The teapot body is a chamber with an opening at the top, and a spout is located at the front end of the opening. The rear wall of the kettle body is provided with a handle, the handle is provided with a flow guide channel, the upper end of the flow guide channel is connected to the chamber and is provided with a flow guide inlet, the lower end of the flow guide channel is provided at the lower part of the handle and is provided with a flow guide outlet, the upper section of the handle is provided with a temperature control switch, and the lower wall of the temperature control switch extends into the upper wall of the flow guide channel. The kettle lid is detachably installed in the opening via a locking device. A water pouring device is provided at the front of the kettle lid, which is used to control the opening or closing of the spout. The rear of the lid is provided with a connecting channel. When the lid is installed in the opening, the connecting channel is connected to the flow inlet.

[0006] In actual design, 1. The handle is modularly designed, integrating the flow channel and steam channel. When hot water overflows due to boiling, the fluid is guided to the flow inlet through the connecting channel. At the same time, the staggered temperature control switch and flow channel do not affect the stability of the control switch. Furthermore, the temperature control switch can still monitor the temperature of the water vapor; 2. The spout can be sealed by the pouring device, which helps to ensure the relative heat preservation effect of the electric kettle. This non-sealed design means that the temperature gradually decreases through a curved channel, reducing the risk of burns. That is, by combining the water pouring device and the internal pipe, hot water is prevented from flowing out of the opening when pouring. Even if it does flow out, it can flow out through the guide channel and the handle, thus effectively reducing the temperature. 3. The bending design of the flow channel can also effectively guide the water vapor, avoiding the problem of scalding from the water vapor. At the same time, because the spout is in the closed state, after boiling, if the water stops for a period of time or is poured at an angle, the density of the water vapor is even lower, so it will be discharged outward through the connecting channel, thus playing a role in relieving pressure.

[0013] like Figures 1 to 11As shown, an electric kettle with an anti-tipping structure includes: The kettle body 1 has a chamber 11 with an opening 10 at its upper end, and a spout 12 is provided at the front end of the opening 10. The rear wall of the kettle body 1 is provided with a handle 2. The handle 2 is provided with a flow channel 20. The upper end of the flow channel 20 is connected to the chamber 11 and is provided with a flow inlet 21. The lower end of the flow channel is provided at the lower part of the handle 2 and is provided with a flow outlet. The upper section of the handle 2 is provided with a temperature control switch 60. The lower wall of the temperature control switch 60 extends into the upper wall of the flow channel 20. The lid 3 is detachably installed in the opening 10 by means of the locking device 4. The front of the lid 3 is provided with a water pouring device 5, which is used to control the opening or closing of the spout 12. The rear part of the lid 3 is provided with a connecting channel 83. When the lid 3 is installed in the opening 10, the connecting channel 83 is connected to the flow inlet 21.

[0014] In actual design, 1. The handle is modularly designed, and the flow channel 20 and the steam channel are integrated. When hot water overflows due to boiling, the fluid is guided to the flow inlet 21 through the connecting channel 83. At the same time, the stability of the control switch is not affected by the staggered temperature control switch 60 and the flow channel 20. Furthermore, the temperature control switch 60 can still monitor the temperature of the water vapor; 2. The sealing of the spout 12 can be controlled by the water pouring device 5, which helps to ensure the relative heat preservation effect of the electric kettle (this design is not a sealed design, which is equivalent to the temperature gradually decreasing through a curved channel). This also prevents hot water from flowing out when pouring. Even if it does flow out, it can flow out through the guide channel 20 and the handle 2, thus effectively reducing the temperature. 3. The bending design of the guide channel 20 can also effectively guide the water vapor, avoiding the problem of water vapor scalding. At the same time, because the spout 12 is in the closed state, after boiling, if it stops for a period of time or is tilted when pouring water, the density of water vapor is smaller, so it will be discharged outward through the connecting channel 83, thus playing a role in depressurization.

[0015] Specifically, the handle 2 is provided with an inner pipe 22 with a bent structure, and the inner pipe 22 is provided with the flow guiding channel 20. The fluid is guided through the relatively sealed inner pipe 22 to reduce the impact on the handle 2.

[0016] In this embodiment of the invention, the inner pipe 22 is provided with a first pipe section, a second pipe section, and a third pipe section that are interconnected. The first pipe section is vertically arranged, the second pipe section is horizontally arranged, and the third pipe section is vertically arranged. The upper wall of the connecting end of the first tube and the second tube is provided with a notch 6, which is used to install the temperature control switch 60.

[0017] This allows the overflow and steam temperature detection to operate without interference. The bent structure also reduces the risk of hot steam or hot water overflowing and scalding hands. In addition, the dual-pipe structure effectively reduces the amount of heat conducted to the handle.

[0018] In this embodiment of the utility model, the inner pipe 22 is flat and includes an inner shell 221 and an outer shell 222. The flat design makes it easier to assemble the temperature control switch 60, reduces structural interference caused by the circular structure, and reduces the difficulty of assembly in detail.

[0019] In this embodiment of the utility model, the lower section of the handle 2 is provided with a hollow groove, and a switch light is installed in the hollow groove to observe the heating status.

[0020] One embodiment may use a liquid color-changing material that changes color when non-water vapor, i.e., liquid, flows in, thereby serving as a warning.

[0021] In this embodiment of the utility model, the handle 2 includes an inner handle integrally welded to the body 1 and an outer cover installed on the inner handle by a snap-fit ​​structure.

[0022] In this embodiment of the invention, the kettle body 1 has multiple studs 23 welded or injection-molded inside. The studs 23 are used to install the inner pipe 22. The temperature control switch 60 is equipped with a temperature-sensing spring, which controls the opening and closing of the temperature control switch 60 via electrical contact or a mechanical structure. (The temperature control switch 60 is an existing design. Using studs 23 to install the inner pipe 22 ensures structural stability, while the one-piece molded inner handle also ensures structural support and improves service life.) The kettle body 1 can have an outer plastic structure and a metal inner liner for water filling, thus preventing scalding, or it can be an all-metal structure.

[0023] The inner tube is made of metal or rigid plastic, preferably metal, which provides better support and cooling, reducing the high temperature of the liquid flowing to the lower part of the handle 2.

[0024] A baffle 13 extending inward is provided at a predetermined distance between the chamber and the opening 10. The predetermined distance is appropriate for the thickness of the lid 3. The baffle 13 abuts against the lid 3, thereby achieving a seal.

[0025] In this embodiment of the invention, the locking device 4 includes locking grooves 41 located on the left and right sides of the opening 10 and locking blocks 42 slidably mounted on the lid 3. The locking block 42 can slide between being locked in the locking groove 41 or being detached from the locking groove 41, thereby realizing the overall disassembly of the lid 3 while ensuring relative sealing.

[0026] In this embodiment of the utility model, the lid 3 is provided with a sliding groove, the locking block 42 is slidably installed in the sliding groove, and a top spring 48 is provided between the locking block 42 and the sliding groove to make the locking block 42 extend out of both sides of the lid 3; The upper wall of the slot 41 is provided with a first inclined surface 43, the upper wall of the card block 42 is a flat surface 45, and the lower wall of the card block 42 is a second inclined surface 44.

[0027] The lid 3 has holes on both sides for the locking block 42 to extend out. The width of the holes is smaller than the rear section of the locking block 42, thus playing a limiting role. The top spring 48 ensures the locking block 42 is locked. At the same time, the cooperation of the first inclined surface 43 and the second inclined surface 44 facilitates the installation of the lid 3.

[0028] Specifically, the upper wall of the lid 3 is provided with a relief groove 46 that cooperates with the locking block 42. The locking block 42 is bent and extended to form a pressing block 47, which extends into the relief groove 46. In use, two fingers simultaneously apply pressure to the pressing block 47 towards the axis, thereby achieving the separation between the lid 3 and the opening 10.

[0029] In this embodiment of the invention, the water pouring device 5 includes a water pouring channel 50 disposed on the lid 3 and a plug 51 oscillatingly mounted on the lid 3. The pivot end of the plug 51 is provided with a torsion spring 52, which is used to drive the plug 51 to close the water pouring channel 50. Specifically, the pouring channel 50 is positioned opposite to the spout 12; Specifically, the lid 3 has a horizontally sliding unlocking block 7 in the middle, the unlocking block 7 has a driving slope 70, and a connecting rod 71 is provided between the rear end of the plug 51 and the driving slope 70. When the protrusion of the driving slope 70 abuts against the connecting rod 71, the connecting rod 71 abuts against the rear end of the plug 51 and causes the plug 51 to move away from the water pouring channel 50.

[0030] The sliding of the unlocking block can be achieved by damping or by using a top spring to keep it in the unlocked state.

[0031] The plug 51, connecting rod 71 and unlocking block 7 are installed in the first positioning cavity 81 of the lid 3 through the first cover body.

[0032] Specifically, the lid 3 is provided with a second positioning cavity, the second positioning cavity 82 is provided with a second cover plate, the second positioning cavity is provided with a floating block 84, and the second positioning cavity is connected to the connecting channel 83. The second positioning cavity protrudes from the lower wall of the kettle lid 3. The front wall of the second positioning cavity is provided with a vent hole 85. Through the cooperation of the second positioning cavity and the float block 84, when the kettle is tilted, the float block 84 is drawn into the connecting channel 83 by negative pressure under the action of water flow, thereby effectively reducing liquid leakage. The cooperation between the first positioning cavity and the second positioning cavity mainly serves to At the same time, the structure of the second positioning chamber for venting effectively reduces scalding caused by air leakage between the lid 3 and the opening 10, and effectively improves the safety of the electric kettle, especially when it is opened.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
