Technical Field
[0001] The utility model relates to the technical field of electric kettles, in particular to a kettle cover structure for preventing water vapor from leaking out. Background Art
[0002] When using an electric kettle to boil water, the water vapor generated when the water boils deforms the bimetallic strip of the steam temperature sensing element. This deformation pushes the power switch to cut off the power through the lever principle, thereby achieving the purpose of automatically cutting off the power after the water boils. However, when the water boils, a large amount of water vapor will remain inside the electric kettle. At this time, if the user removes the kettle lid from the top of the electric kettle, the large amount of water vapor will cause scalds to the user's hands, posing a great safety hazard. Some existing kettle lid structures that can reduce the risk of scalding the user caused by overflow of water vapor still have some problems during use.
[0003] For example, the Chinese patent publication number CN218635824U discloses an electric kettle lid structure that prevents water vapor from overflowing, comprising: an electric kettle and a lid, the lid is located at the top of the electric kettle and is used in conjunction with the electric kettle, a sealing ring is fixedly connected to the top of the inner cavity of the electric kettle, the inner wall of the sealing ring is in contact with the lid, a sealing cylinder is fixedly connected to the left side of the top of the inner cavity of the lid, and two flow holes are provided on the left side of the top of the lid. The utility model has the advantage of good safety. In actual use, when the sealing between the electric kettle and the lid is good, water vapor will be retained in the inner cavity of the electric kettle. At this time, the operating block is pressed to one side so that the water vapor inside the electric kettle can be dispersed in a controlled manner. Then, when the user takes the lid off the top of the electric kettle, it is prevented that the water vapor causes burns to the user's hands.
[0004] The sealing plug structure cooperated with the spring above seals the kettle lid to prevent water vapor from overflowing. Before opening the kettle lid, the sealing structure needs to be opened first so that the water vapor can be completely dispersed before the kettle lid can be opened normally. It is relatively cumbersome to use. In addition, during the process of boiling water, the kettle is in a sealed space through the sealing structure. As the temperature rises, the pressure in the kettle increases, which poses a great safety hazard. When the pressure is released to release the water vapor, the seal is opened by pushing the seal open, so that the user's hand is still at a close distance to the water vapor, which also poses a safety hazard and has low practicality. Therefore, the present application provides an electric kettle lid structure that prevents water vapor from overflowing to meet the needs. Utility Model Content

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] Example 1: Reference Figure 1-3The lid structure of an electric kettle for preventing water vapor from leaking out is shown, comprising a kettle body 1 and a kettle lid 2 spirally mounted on the top of the kettle body 1, a handle 4 is arranged on the side wall of the kettle body 1, an electric heating base 5 is arranged at the bottom of the kettle body 1, an electric heating switch 6 is arranged on the electric heating base 5, a water vapor isolation unit 7 for collecting water vapor when boiling water is arranged on the kettle body 1, the water vapor isolation unit 7 comprises a pair of elastic air bags 8 connected with the inside of the kettle body 1, when boiling water, the water vapor generated is stored in the elastic air bags 8 for isolation, so as to reduce the water vapor from leaking out when the kettle lid 2 is opened, thereby replacing the existing result of water vapor from leaking out, and the kettle lid 2 can be directly opened without first relieving pressure, thereby improving the safety and convenience of use.
[0024] A pair of mounting seats 9 are fixedly connected inside the kettle body 1, a slide groove 10 is provided on the mounting seat 9, a through hole 11 is provided on the slide groove 10, and the through hole 11 is communicated with the elastic airbag 8, a slide plate 12 is slidably connected to the slide groove 10, a guide rail 13 is fixedly connected to the slide groove 10, and the slide plate 12 is slidably connected to the guide rail 13, the cross-section of the slide plate 12 is an L-shaped structure, and a friction block 14 is provided on the top of the slide plate 12, and the friction block 14 is an elastic rubber anti-slip structure, which is the prior art.
[0025] When boiling water, first, the pot cover 2 is screwed on the pot body 1 with a screw. As the pot cover 2 is screwed in, the bottom end of the pot cover 2 first contacts the elastic rubber anti-skid structure of the friction block 14. As the pot cover 2 rotates in a spiral, under the guidance of the guide rail 13, the friction block 14 is pushed to move, thereby driving the slide plate 12 to move so that the slide plate 12 is separated from the through hole 11, thereby connecting the pot body 1 with the elastic air bag 8. As the water temperature rises, the pressure in the pot body 1 increases, and the water vapor is stored in the elastic air bag 8, which makes the elastic air bag 8 expand, reduces the pressure, and improves the safety of use. After the water is boiled, the pot cover 2 is rotated in the opposite direction, and the slide plate 12 is driven to cover the through hole 11 in the same way, so that the water vapor is stored in the elastic air bag 8 and isolated from the outside until the pot cover 2 is spirally opened, reducing the overflow of water vapor, improving the opening safety and convenience of use. Before the next water boiling, the cooled water vapor can be actively pushed to move the slide plate 12, so that the through hole 11 is opened, so that the water vapor overflows, which is convenient for the next use.
[0026] Embodiment 2: Embodiment 1 is further optimized, specifically, as Figure 3As shown, a spout 3 is provided on one side of the top of the kettle body 1, and a sealing plug 15 is rotatably connected to the position of the kettle lid 2 near the spout 3 in the kettle body 1, and a torsion spring is provided at the rotational connection position between the kettle body 1 and the sealing plug 15. When the kettle lid 2 is closed, the sealing plug 15 is pushed to rotate, thereby driving the sealing plug 15 to block the spout 3, so that the kettle body 1 is in a relatively sealed structure, further reducing the overflow of water vapor and improving the safety of boiling water. At the same time, after the kettle lid 2 is opened, the sealing plug 15 is automatically opened under the action of the torsion spring, which does not affect normal use and has high practicality.
