[0021] To better understand the purpose, structure, and function of this invention, a detailed description of an electric kettle of this invention is provided below with reference to the accompanying drawings.
[0022] like Figure 1 As shown, the electric kettle of the present invention includes a kettle body 1, a kettle lid 2, and a spout 3. The kettle lid 2 is closed at the top opening of the kettle body 1. The bottom end of the spout 3 is fixedly connected to the bottom side wall of the kettle body 1 and communicates with the kettle body 1. A check valve 4 is provided at the top opening of the spout 3 to prevent dust or insects from entering the kettle body 1 from the spout 3. At the same time, when the water boils, part of the steam is ejected through the vent hole of the kettle lid 2 and the other part is ejected from the spout 3, which is safe and hygienic.
[0023] like Figure 2As shown, the check valve 4 includes an inner shell 41 fixed to the inner wall of the spout 3, and a valve body 43 is provided inside the inner shell 41. The water passage of the inner shell 41 is opened or closed by the valve body 43 to open or close the spout 3.
[0024] To improve the closing effect of the valve body 43, the water passage of the inner shell 41 is a stepped hole consisting of a small-diameter first through hole and a large-diameter second through hole along the water flow direction. The valve body 43 cooperates with the stepped hole to open or close the water passage.
[0025] In order to increase the contact area between the valve body 43 and the stepped hole, a conical surface inclined toward the valve body 43 is provided between the small-diameter first through hole and the large-diameter second through hole, and the valve body 43 is a frustum that mates with the aforementioned conical surface.
[0026] The side wall of the cone is provided with an annular limiting groove, and a first sealing ring 45 is provided in the limiting groove to enhance the sealing effect.
[0027] The check valve 4 also includes a connecting sleeve 42 fitted into the inner wall of the inner shell 41. A limiting plate 421 is provided at the end of the connecting sleeve 42 away from the valve body 43. An annular plate is provided at the center of the limiting plate 421. A valve stem 44 is provided at the center of the valve body 43 facing the limiting plate 421. The end of the valve stem 44 passes through the annular plate and moves along the annular plate. A water outlet hole is provided on the limiting plate 421. The annular plate serves as a guide and limits the maximum range of movement of the valve body 43.
[0028] In order to automatically close the valve body 43 after water is discharged, the valve body 43 is made of elastic materials such as rubber and silicone, and the valve stem 44 is made of metal or stainless steel. The end of the valve stem 44 is provided with a spherical structure, which is fixed to the valve body 43 by interference fit.
[0029] In addition, the spout 3 can be set to a vertical or near-vertical position, for example, the angle between the axis of the spout 3 and the horizontal plane is between 85-90°.
[0030] Furthermore, an annular groove is provided on the outer wall of the inner shell 41 at the first through hole, and a second sealing ring 46 is fitted inside the annular groove to achieve a sealing effect between the inner shell 41 and the spout 3.
[0031] This electric kettle has a dustproof structure with a check valve 4 at the end of the spout 3, which can prevent dust from entering the inside of the spout 3, thereby improving the hygiene inside the kettle body 1. By setting a one-way valve, it can ensure normal water output and also ensure the hygiene inside the kettle. When the water boils, it can spray out from the vent hole of the lid 2 and also from the check valve 4 structure, which greatly reduces safety hazards.
