[0031] In the description of the present invention, "multiple" means at least two, such as two, three, etc., unless otherwise clearly defined. In addition, unless otherwise clearly defined and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it 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 indirectly connected 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.
[0032] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0033] In the first aspect, the utility model provides a technical solution: a tipping and overflow prevention pot cover structure, comprising a lower cover plate 1 and an upper cover plate 2, a side surface of the lower cover plate 1 is provided with a circular channel, the circular channel comprises an inner ring 3, an outer ring 4 and a baffle 5, two ends of the baffle 5 are respectively fixedly connected to the outer side wall of the inner ring 3 and the inner side wall of the outer ring 4, at least one circular side plate 6 with a notch 7 is provided between the inner ring 3 and the outer ring 4, the center of the circular side plate 6 overlaps with the center of the inner ring 3, one end of the circular side plate 6 is fixedly connected to the baffle 4, and the other end of the circular side plate 6 does not contact the baffle 4 to form the notch 7, at least one air inlet 8 is provided on the lower cover plate 1, the air inlet 8 is close to the baffle 5 and outside the inner ring 3, an air outlet 9 is provided on the outer ring 4, the upper cover plate 2 is covered on one side surface of the lower cover plate 1 provided with the circular channel, and the upper cover plate 2 is sealed and matched with the lower cover plate 1.
[0034] For details, see Figure 1 and Figure 2When boiling water, the generated steam enters the circular channel composed of the inner ring 3, the outer ring 4, the baffle 5 and the circular side plate 6 from the air inlet 8 opened in the lower cover plate 1. The circular side plate 6 divides the circular channel into several small channels, and the adjacent small channels are connected through the notch 7 of the circular side plate 6. The notch 7 of the circular side plate 6 is opened at the baffle 5 (that is, one end of the circular side plate 6 is welded to the baffle 5, and the other end of the circular side plate 6 is not connected to the baffle 5). In this way, the steam enters another small channel from one small channel at the notch 7 until it flows to the air outlet 9, effectively draining the steam from the pot and discharging it, thereby reducing the pressure in the pot. Since the air outlet 9 is on the outer ring 4 (that is, on the side wall of the pot cover), compared with the traditional steam outlet opened above the pot cover, the risk of steam scalding the user when pouring water is effectively avoided. In addition, when the electric kettle is accidentally tipped over, the hot water in the kettle will inevitably enter the kettle cover, so there is a risk of hot water overflowing from the kettle cover. However, when the electric kettle is tipped over, even if a small amount of hot water enters the kettle cover, due to the design of the circular side plate 6 and the baffle plate 5, the small amount of hot water will be intercepted and diverted by the baffle plate 5 when it flows, and finally, the water line of the hot water will not be higher than the highest point of the circular side plate 6 (see Figure 3 and Figure 4 ), hot water cannot flow through, thereby achieving an anti-overflow effect. Moreover, under this design, the kettle lid can be in any position of 360° without being fixed. Since the air outlet 9 of the kettle lid is opened at a higher position of the outer ring 4, there is a height difference with the air inlet 8. Even if too much hot water enters the kettle lid, the amount of hot water overflowing from the air outlet 9 can be controlled to a minimum to avoid scalding the user. When the overturned electric kettle is straightened, since the upper surface of the lower cover 1 is inclined from the outside to the inside (high outside and low inside), the condensed water and the hot water entering the kettle lid are diverted back to the air inlet 8 to avoid overflowing from the air outlet 9. Among them, the number of circular side plates 6 can be adjusted according to actual conditions to meet the overflow prevention requirements. When multiple circular side plates 6 are set, the center of the multiple circular side plates 6 overlaps with the center of the inner ring, and two adjacent circular side plates 6, one end of one circular side plate 6 is welded to the left side of the baffle 5, and the notch 7 of the circular side plate 6 is on the right side of the baffle 5, and one end of the other circular side plate 6 is welded to the right side of the baffle 5, and the notch 7 of the circular side plate 6 is on the left side of the baffle, that is, a turning channel is formed by multiple circular side plates 6 in the circular channel.
[0035] As an optional implementation, in some embodiments, a plurality of mounting frames 10 are further provided on the lower cover plate 1, and the mounting frames 10 are fixedly connected to the outer side wall of the outer ring 4. The mounting frames 10 are used to install a seal, which can cooperate with the pot mouth to seal and prevent steam and hot water from leaking from the gap between the pot cover and the pot mouth when the electric kettle is tipped over.
[0036] In the above embodiment, further, a plurality of mounting frames 10 are arranged at equal intervals along the circumference of the outer ring 4. When the seal is installed in this design, the installation is more stable and the sealing effect is better.
[0037] As an optional implementation, in some embodiments, the number of the plurality of installation frames 10 is four, wherein this number of installation frames 10 can meet general installation requirements, and of course, the number of installation frames 10 can be adjusted according to actual needs.
[0038] As an optional implementation, in some embodiments, a handle 11 is provided on the upper surface of the upper cover plate 2. Figure 5 Among them, the setting of the handle 11 makes it convenient for the user to lift the pot lid.
[0039] As an optional implementation, in some embodiments, the number of the air inlets 8 is two, and the two air inlets 8 are symmetrically arranged. Figure 2 Increasing the number of air inlets 8 helps steam enter the circular channel, thereby achieving the effect of quickly reducing the pressure in the kettle. The number of air inlets 8 can be adjusted according to actual needs to meet the pressure reduction requirements; the symmetrical arrangement of the two air inlets 8 is more beautiful.
[0040] As an optional implementation, in some embodiments, the lower cover plate 1 is further provided with a partition plate 12, and the partition plate 12 is located in the middle of the air outlet 9. Figure 1 The air outlet 9 is divided into two halves by a partition 12, which has a diversion effect and avoids concentrated discharge of steam.
[0041] In a second aspect, the utility model provides a technical solution: an electric kettle, comprising a kettle body and the above-mentioned kettle cover, wherein the kettle cover is arranged at the mouth of the kettle body. Figure 7 The kettle cover of the utility model is suitable for various types of heated electric kettles, such as ceramic electric kettles, stainless steel electric kettles, glass electric kettles, etc. As the electric kettle is heated, a large amount of high-temperature steam will be generated in the kettle body. The kettle cover can effectively discharge the steam and release the pressure in the kettle body. At the same time, it can also prevent hot water from overflowing or control the hot water overflow to a minimum when the electric kettle is tipped over.
