Description

Technical Field

[0001] This utility model relates to the field of electric kettle technology, specifically to an anti-overflow electronic kettle. Background Technology

[0002] Electric kettles are common household appliances. An electric kettle mainly consists of a kettle body and a lid, with the lid fitting onto the kettle body. Most electric kettles include a kettle body and a lid. One side of the kettle body has a spout, and the other side has a handle. The lid is hinged to the handle to cover the kettle spout.

[0003] When water in an electric kettle reaches its boiling point and begins to boil, people usually act quickly to pour out the hot water. However, even at the moment the water is poured out, it is still actually boiling. This boiling water, due to its active movement, easily overflows along the seam between the lid and the kettle body during the pouring process. Furthermore, the large amount of steam generated by the boiling water is also poured out along with the hot water. This scalding steam not only increases the risk of burns but may also pose a hazard to the surrounding environment. Therefore, we propose an overflow-proof electronic kettle. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-overflow electronic kettle in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] An anti-overflow electronic kettle includes an electronic kettle body, a lid, and a power-connecting base. The lid is inserted and fixed to the upper end of the electronic kettle body, and the bottom of the electronic kettle body is aligned with the upper end of the power-connecting base. A docking hole is formed at the center of the bottom of the electronic kettle body, and a central sleeve is fixedly connected to the outer edge of the docking hole. A mounting ring is movably fitted onto the central sleeve, and a resistance heating plate is fixedly connected to the upper end of the mounting ring. A heating kettle bottom is fixedly connected to the lower side of the bottom of the electronic kettle body. A compression spring is fitted on the outer wall of the mounting ring, and the upper and lower ends of the compression spring abut against the heating kettle bottom and the mounting ring, respectively. A power plug is fixedly connected to the center of the upper end of the power-connecting base, and a central rubber post is fixedly connected to the center of the bottom of the resistance heating plate corresponding to the docking hole at the bottom of the electronic kettle body. Both the power plug and the central rubber post are matched with the docking hole at the bottom of the electronic kettle body.

[0007] Furthermore, the power plug is connected to a household power source via a power cord, and the electrical components inside the electronic kettle body and the power supply terminals of the resistance heating plate are electrically connected to the power plug via a contact conductive mechanism.

[0008] Furthermore, the contact conductive mechanism includes a plug conductive contact and a kettle body conductive contact. The plug conductive contact is electrically connected to the power supply terminal of the internal circuit of the electronic kettle, and the power plug is electrically connected to the power line in the power base. The plug conductive contact is embedded in the side wall of the power plug, and the kettle lid is embedded in the bottom of the inner wall of the central sleeve. The position of the plug conductive contact corresponds to the position of the central sleeve.

[0009] Furthermore, a frustum base is provided on the outer ring of the upper center of the power connection chassis corresponding to the installation position of the power connection plug, and a mating groove is provided on the bottom center of the electronic kettle body.

[0010] Furthermore, a limit stop ring is fixedly connected to the lower edge of the outer wall of the mounting ring seat, and the bottom of the compression spring abuts against the upper end of the limit stop ring.

[0011] Furthermore, a boiling-suppressing baffle is fixedly connected to the upper end of the inner wall of the electronic kettle near the lower edge of the water outlet.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model features an electronic kettle body. The bottom of the electronic kettle body forms a heating chamber on the upper side of the inner cavity through a heating bottom seal. A resistance heating plate is installed, which is powered through the docking of the electronic kettle body and the power-connecting base. The electronic components inside the electronic kettle body control the start-up. When the resistance heating plate is in close contact with the bottom of the heating pot, it can heat the water loaded at the top of the electronic kettle body. When heating is complete, the user holds the handle of the electronic kettle body and lifts it. The bottom of the electronic kettle body separates from the power-connecting base, and the power plug is pulled out from the docking hole at the bottom of the electronic kettle body. The mounting ring seat moves down under the return force of the compression spring, causing the resistance heating plate to separate from the bottom of the heating pot. The air layer between the resistance heating plate and the bottom of the heating pot reduces heat transfer, thereby greatly reducing the boiling amplitude of the water in the electronic kettle body and effectively avoiding the risk of boiling water overflowing when tilting. Meanwhile, after the electronic kettle is lifted, the central rubber column is pushed into the central sleeve by the resistance heating plate, sealing the bottom docking hole of the electronic kettle, preventing water from entering the bottom of the electronic kettle, improving the waterproof performance of the electronic kettle during use, effectively solving the problem of boiling water easily overflowing when the existing electric kettle is poured, and improving the safety and convenience of use.

[0014] 2. This utility model, through its designed contact conductive mechanism, achieves a stable electrical connection between the power supply terminals of the electrical components and the resistance heating plate within the electronic kettle body and the power connector, ensuring the normal operation of the electronic kettle body. Simultaneously, the contact conductive mechanism has a simple structure, is easy to install and maintain, and reduces production costs.

[0015] 3. By setting up a boiling-suppressing screen, this utility model can further break up the remaining small bubbles after the electronic kettle body is lifted and the resistance heating plate is separated from the bottom of the kettle, thereby reducing the fluctuation range of the boiling water surface in the electronic kettle and further improving the anti-overflow effect.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] Please see Figures 1-3 This utility model provides an anti-overflow electronic kettle, including an electronic kettle body 1, a kettle lid 2, and a power-connecting base 3. The kettle lid 2 is inserted and fixed to the upper end of the electronic kettle body 1, and the bottom of the electronic kettle body 1 is connected to the upper end of the power-connecting base 3. A docking hole is opened in the center of the bottom of the electronic kettle body 1, and a central sleeve 13 is fixedly connected to the outer edge of the bottom of the electronic kettle body 1 corresponding to the docking hole. A mounting ring seat 8 is movably sleeved on the central sleeve 13, and a resistance-type heating element is fixedly connected to the upper end of the mounting ring seat 8. The heating plate 7 and the bottom of the electronic kettle body 1 are fixedly connected to the heating kettle bottom 6. The outer wall of the mounting ring seat 8 is fitted with a compression spring 10. The upper and lower ends of the compression spring 10 abut against the heating kettle bottom 6 and the mounting ring seat 8, respectively. The upper center of the power connection base 3 is fixedly connected to the power plug 4. The bottom center of the resistance heating plate 7 is fixedly connected to the bottom docking hole of the electronic kettle body 1. The power plug 4 and the central rubber post 11 are both matched with the bottom docking hole of the electronic kettle body 1.

[0022] In this embodiment, preferably, the power plug 4 is connected to a household power source via a power cord. The electrical components inside the electronic kettle body 1 and the power supply terminals of the resistance heating plate 7 are all electrically connected to the power plug 4 via a contact conductive mechanism. This contact conductive mechanism ensures a stable electrical connection between the electrical components inside the electronic kettle body 1, the power supply terminals of the resistance heating plate 7, and the power plug 4, guaranteeing the normal operation of the electronic kettle body 1. Furthermore, the contact conductive mechanism has a simple structure, is easy to install and maintain, and reduces production costs.

[0023] In this embodiment, preferably, the contact conductive mechanism includes a plug conductive contact 5 and a kettle body conductive contact 12. The plug conductive contact 5 is electrically connected to the power supply terminal of the circuit inside the electronic kettle body 1, and the power plug 4 is electrically connected to the power cord inside the power receiving chassis 3. The plug conductive contact 5 is embedded in the side wall of the power plug 4, and the kettle lid 2 is embedded in the bottom of the inner wall of the central sleeve 13. The positions of the plug conductive contact 5 and the central sleeve 13 are correspondingly arranged. Through the configured plug conductive contact 5 and kettle body conductive contact 12, when the power plug 4 is inserted into the mating hole at the bottom of the electronic kettle body 1, the plug conductive contact 5 and the kettle body conductive contact 12 make close contact, thereby realizing the circuit conduction and providing power to the resistance heating plate 7 and the electrical components inside the electronic kettle body 1. This contact conductive mechanism design not only ensures the stability of power transmission, but also makes the connection between the electronic kettle body 1 and the power receiving chassis 3 simpler and faster, improving the user experience.

[0024] In this embodiment, preferably, a frustum base is provided on the outer ring of the upper center of the power-connecting base 3 corresponding to the installation position of the power plug 4, and a docking groove is provided on the bottom center of the electronic kettle body 1. The frustum base and docking groove ensure a more stable connection between the power-connecting base 3 and the electronic kettle body 1 during docking, preventing shaking or misalignment, thus guaranteeing the normal operation of the electrical components and resistance heating plate 7 within the electronic kettle body 1. Simultaneously, this design improves the docking accuracy between the electronic kettle body 1 and the power-connecting base 3, allowing the plug's conductive contacts 5 and the kettle body's conductive contacts 12 to make closer contact, thereby improving circuit conductivity and power transmission efficiency. The power plug 4 protrudes towards the center relative to the power-connecting base 3, allowing gravity to expel any water droplets that seep in, thus improving the waterproof effect of the electronic kettle.

[0025] In this embodiment, preferably, a limiting ring 9 is fixedly connected to the lower edge of the outer wall of the mounting ring seat 8, and the bottom of the compression spring 10 abuts against the upper end of the limiting ring 9; the setting of the limiting ring 9 facilitates the installation of the compression spring 10.

[0026] In this embodiment, preferably, a boiling-suppressing baffle 14 is fixedly connected to the upper end of the inner wall of the electronic kettle body 1 near the lower edge of the water outlet. By setting the boiling-suppressing baffle 14, after the electronic kettle body 1 is lifted and the resistance heating plate 7 is separated from the bottom of the kettle 6, the boiling-suppressing baffle 14 can further break up the remaining small bubbles, reduce the fluctuation range of the boiling water surface in the electronic kettle body 1, and further improve the anti-overflow effect.

[0027] The working principle and usage process of this utility model are as follows: In use, the electronic kettle body 1 has a heating chamber formed on the upper side of its inner cavity through a heating base 6. A resistance heating plate 7 is connected to the electronic kettle body 1 via a connection to the power base 3. The heating is controlled by electronic components within the electronic kettle body 1. When the resistance heating plate 7 is in close contact with the bottom of the heating base 6, it heats the water loaded at the top of the electronic kettle body 1. When the user lifts the electronic kettle 1 by holding the handle, the bottom of the kettle 1 separates from the power base 3, and the power plug 4 is pulled out from the bottom connection hole of the kettle 1. The mounting ring 8 moves downward under the return force of the compression spring 10, causing the resistance heating plate 7 to separate from the bottom of the kettle 6. The air layer between the resistance heating plate 7 and the kettle bottom 6 reduces heat transfer, significantly reducing the boiling point of the water inside the kettle 1 and effectively preventing the risk of boiling water overflowing when tilted. Simultaneously, after the kettle 1 is lifted, the central rubber post 11, pushed by the resistance heating plate 7, inserts into the central sleeve 13, sealing the bottom connection hole of the kettle 1 and preventing water from entering the bottom. This improves the kettle's waterproofness and effectively solves the problem of boiling water easily overflowing when tilting existing electric kettles, improving safety and convenience.
