For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.
[0042] To solve the above problems, Figure 1 , Figure 2 As shown, an embodiment of the present application provides an electric kettle, comprising: a shell 11, an inner pot 10, a pot mouth ring assembly 111, and an openable and closable pot cover 1 arranged on the top of the pot mouth ring assembly 111;
[0043] Among them, the outer shell 11 wraps the inner liner 10, and there is a gap between the two to prevent heat from being directly transferred from the inner liner 10 to the outer shell 11. The inner liner 10 can be made of glass material, and the outer shell 11 can be made of plastic or metal material; a pot mouth ring assembly 111 is provided on the upper part of the outer shell 11, and the lower part of the pot mouth ring assembly 111 is abutted against the outer shell 11, and the outer wall of the lower end of the pot mouth ring assembly 111 is fixedly connected to the outer shell 11 and there is also a gap between the inner liner 10; the outer shell 11, the pot mouth ring assembly 111 and the pot cover 1 enclose the inner liner 10 inside, the inner liner 10 is not exposed, and the handle can be installed on the outer shell 11, avoiding the existing handle directly installed on the glass inner liner 10 The way that the inner liner 10 is fragile due to unilateral force; at the same time, even if the inner liner 10 in the present application is broken, the fragments of the inner liner 10 and water will not splash out to injure the user.
[0044] Preferably, the mouth ring assembly 111 and the opening edge 101 of the inner liner, as well as the outer shell 11 and the lower end of the inner liner 10 are sealed by a first adhesive layer to prevent water from entering the gap between the outer shell 11 and the inner liner 10 or entering the bottom 26 of the pot during use.
[0045] The mouth ring assembly 111 is provided with a spout 9 , which may be a triangular spout 9 protruding from the side of the mouth ring assembly 111 . The mouth ring assembly 111 is provided with a filter 8 at the installation position corresponding to the spout 9 .
[0046] In one embodiment of the present application, the inner wall of the outer shell 11 can be provided with transverse or longitudinal ribs to increase the strength of the outer shell 11 itself; in order to prevent the outer shell 11 or the pot mouth ring assembly 111 from directly transmitting the external force received to the inner liner 10, on the one hand, the outer shell 11 and the pot mouth ring assembly 111 are both provided with a gap with the inner liner 10, and on the other hand, the lower end of the pot mouth ring assembly 111 is fixed to the opening edge 101 of the inner liner by means of snap connection, elastic connection or buffer connection, thereby reducing the probability of the inner liner 10 breaking. At the same time, the mutual buffering effect between the outer shell 11 and the inner liner 10 makes the outer shell 11 itself not easy to deform or break, thereby improving the anti-fall effect. Even if the inner liner 10 breaks, the fragments are sealed inside and will not hurt people.
[0047] Preferably, a first groove is formed on the inner wall of the lower end of the pot mouth ring assembly 111, and the edge 101 of the inner liner opening is accommodated in the first groove through an elastic member or a buffer medium.
