SUMMARY

[0004] In view of the deficiencies of prior art, the utility model provides a kind of pour anti-overflow kettle cover and the electric kettle containing the kettle cover, to reduce the situation that boiling water from exhaust hole overflows when electric kettle is poured, improve the safety and practicality of electric kettle.

[0005] To achieve the above object, the utility model provides the following technical scheme:

[0006] First, a kind of pour anti-overflow kettle cover is provided, including lower cover, the lower cover is equipped with air outlet, the bottom of the lower cover is rotatably connected with rotating block, the one end of the rotating block is provided with communication slot along length direction, the communication slot is communicated with the air outlet.

[0007] Preferably, it further includes the upper cover connected with the top of the lower cover, the upper cover is equipped with exhaust hole, the exhaust hole is communicated with the air outlet.

[0008] Preferably, the bottom of the upper cover is protruded with protrusion, the bottom of the upper cover, the protrusion and the top of the lower cover form containing cavity for containing liquid, the containing cavity is communicated with the air outlet and the exhaust hole respectively.

[0009] Preferably, the outer side wall of the lower cover is equipped with sealing element for sealing electric kettle spout.

[0010] Preferably, the sealing member is a plurality of silica gel rings arranged around the outer sidewall of the lower cover.

[0011] Preferably, the bottom of the lower cover is fixedly connected with a connecting pipe, the connecting pipe is in communication with the air outlet, an outer wall of the connecting pipe is connected with a rotating bearing, an inner sleeve of the rotating bearing is fixedly connected with the connecting pipe, and an outer sleeve of the rotating bearing is fixedly connected with the rotating block.

[0012] Preferably, the rotating block is embedded with a counterweight at one end away from the communication groove in the length direction.

[0013] Preferably, the upper cover and the lower cover are ultrasonically connected.

[0014] Preferably, the top of the upper cover is provided with a handle.

[0015] In the second aspect, the utility model provides an electric kettle, which comprises a kettle body and a pouring anti-overflow kettle cover as described above arranged at the kettle opening of the kettle body.

[0016] The above technical scheme has the following beneficial effects:

[0017] 1. When the electric kettle is normally boiling water, steam can smoothly enter the communication groove in the rotating block, and then enter the air outlet of the lower cover to be discharged into the air, thereby ensuring the balance of the pressure in the kettle during the boiling process and ensuring the normal operation of the boiling work. Since the communication groove is arranged at one end of the rotating block in the length direction, one end of the rotating block in the length direction is hollow, and the other end is solid, so that the center of gravity of the rotating block is located at the end of the rotating block away from the communication groove in the length direction. When the kettle is poured, the end where the center of gravity of the rotating block is located will turn in the direction in which the kettle is poured, and the end provided with the communication groove will turn in the opposite direction of the pouring direction, and will be above the horizontal plane after pouring, so that the hot water in the kettle is not easy to flow to the communication groove, thereby reducing the situation that the hot water in the kettle flows from the communication groove to the air outlet and overflows to the outside of the kettle, and reducing the safety accidents such as scalding caused by the overflow of hot water. The user is provided with reliable safety protection in various use scenarios.

[0018] 2. When the electric kettle is poured, the communication groove, the air outlet and the exhaust hole are always in communication, that is, the inside of the electric kettle is always in communication with the air. Compared with the design that the exhaust hole is immediately closed after the electric kettle is poured, the setting of the utility model avoids the situation that the electric kettle is poured after boiling, the internal thermal inertia continues to heat, the pressure in the kettle increases, especially when the kettle cover is opened in the middle of the boiling process and then poured, if the exhaust hole is closed, the cold air entering the kettle is heated, which can cause the internal pressure of the kettle to increase instantaneously, and the kettle cover may be blown off, which can cause serious safety hazards.

[0019] 3、The sealing element arranged on the outer wall of the lower cover can tightly fit the spout of the electric kettle, and can effectively prevent the water in the kettle from overflowing from the gap between the spout and the cover under various conditions such as normal use and pouring of the electric kettle, thereby enhancing the overall sealing performance; meanwhile, when a large amount of steam is generated due to boiling of the water in the kettle, the sealing element on the outer wall of the lower cover can stably support the cover by virtue of the friction force and supporting force generated by the tight fitting of the sealing element on the outer wall of the lower cover on the spout, thereby preventing the cover from being pushed out by the steam and ensuring safe and smooth boiling of water.

[0020] 4、When the electric kettle is poured, if the water in the electric kettle is too much, the water in the kettle will flow from the communication groove and the air outlet hole to the exhaust hole, and the accommodation cavity is arranged between the air outlet hole and the exhaust hole, the accommodation cavity can accommodate the overflow liquid, avoid the liquid directly overflow from the exhaust hole, further strengthen the anti-overflow effect of the cover.

[0021] 5、The utility model discloses simple structure, and the cover is mainly constituted by upper cover and lower cover, and the rotating block is connected with the lower cover through the rotating bearing and the connecting pipe, and the component design is simple. DRAWINGS

[0036] Embodiment 1

[0037] Referring to Figure 1 and Figure 3 The embodiment 1 of the present application discloses a pouring anti-overflow kettle cover, which comprises an upper cover 1 and a lower cover 2 connected to the bottom of the upper cover 1, the top of the upper cover 1 is provided with an air vent 11, the top of the lower cover 2 is provided with an air outlet 21, the bottom of the lower cover 2 is rotatably connected with a rotating block 32, the rotating block 32 is provided with a communication groove 33 at one end along the length direction, the communication groove 33 is communicated with the air outlet 21, the air outlet 21 is communicated with the air vent 11, and the center of gravity of the rotating block 32 is located at the end of the rotating block 32 away from the communication groove 33 along the length direction.

[0038] Specifically, the air outlet 21 is arranged at the center of the top of the lower cover 2, the bottom of the lower cover 2 is fixedly connected with a connecting pipe 22, the connecting pipe 22 is located at the center of the bottom of the lower cover 2, the connecting pipe 22 is in communication with the air outlet 21, the outer side of the connecting pipe 22 is connected with a rotating bearing 31, the outer wall of the connecting pipe 22 is fixedly connected with the inner sleeve of the rotating bearing 31, the outer sleeve of the rotating bearing 31 is fixedly connected with a rotating block 32, and a communication groove 33 is in communication with the connecting pipe 22. In the embodiment, the rotating block 32 is a rectangular block, and the slot of the communication groove 33 is arranged on the side wall of one end of the rotating block 32 in the length direction. When boiling water normally, the steam in the kettle can be smoothly discharged to the atmosphere through the communication groove 33, the connecting pipe 22, the air outlet 21 and the exhaust hole 11, so as to ensure the pressure balance in the kettle and guarantee the normal boiling of water; since the communication groove 33 is arranged on one end of the rotating block 32 in the length direction, the center of gravity of the rotating block 32 is located at the end of the rotating block 32 away from the communication groove 33 in the length direction. When the kettle is poured, the rotating block 32 rotates, the slot of the communication groove 33 is turned to the direction opposite to the pouring of the electric kettle and exceeds the horizontal plane, which is beneficial to prevent hot water from overflowing from the exhaust hole 11, reduce the risk of scalding safety accidents and provide safety protection.

[0039] The communication groove 33, the air outlet 21 and the exhaust hole 11 in the utility model always maintain the state of communication. Compared with the situation that the exhaust hole 11 is immediately closed after the electric kettle is poured in the traditional design, the setting of the utility model has very obvious safety advantages. Taking the example of opening the kettle cover in the middle of the boiling process and then pouring, in the traditional design, the exhaust hole 11 is closed, and the cold air entering the kettle will cause the internal pressure of the kettle to instantaneously increase due to heating, and then the kettle cover will be extremely likely to be blown off, causing serious safety hazards. However, the pouring overflow prevention kettle cover of the utility model effectively avoids this situation because of the communication state. Even when the kettle is poured and the internal water continues to warm up due to thermal inertia, the pressure can be balanced and released because of the communication between the inside and the air, and the danger of the kettle cover being blown off due to the sharp increase in pressure will not occur, which provides more reliable safety protection for the user and greatly improves the safety and practicality of the electric kettle in various use scenarios.

[0040] Referring to Figure 2 , preferably, a counterweight 34 is embedded in the side wall of the end of the rotating block 32 away from the communication groove 33 in the length direction. The setting of the counterweight 34 can increase the counterweight of the end of the rotating block 32 away from the communication groove 33, which is beneficial to improve the response speed of the rotating hole when the kettle is poured.

[0041] Referring to Figure 2 , Figure 3 and Figure 4The bottom of the upper cover 1 protrudes a protrusion 13, the bottom of the upper cover 1, the protrusion 13 and the top of the lower cover 2 form a containing cavity 14 for containing liquid, the containing cavity 14 is communicated with the air outlet hole 21 and the air exhaust hole 11 respectively. Specifically, the air outlet hole 21 is located at the center of the lower cover 2, the air exhaust hole 11 is close to the edge of the upper cover 1, the cross section of the containing cavity 14 is in the shape of an irregular curved channel, and the containing cavity 14 has two ends, one end of the containing cavity 14 is communicated with the air outlet hole 21, and the other end of the containing cavity 14 is communicated with the air exhaust hole 11. When the electric kettle is poured, if the electric kettle is inclined at a large angle or the water level in the electric kettle is high, the liquid in the kettle may overflow to the air exhaust hole 11, and the containing cavity 14 is arranged between the air exhaust hole 11 and the air outlet hole 21, which can contain the overflow liquid and prevent it from overflowing directly from the air exhaust hole 11, thereby enhancing the anti-overflow effect of the kettle cover.

[0042] Referring to Figure 3 The outer side wall of the lower cover 2 is provided with a sealing element 23 for sealing the spout of the electric kettle. The sealing element 23 is a plurality of silica gel rings arranged around the outer side wall of the lower cover 2. In this embodiment, three silica gel rings are provided, and the three silica gel rings are arranged on the outer side wall of the lower cover 2. By arranging the sealing element 23, on the one hand, in various use states of the electric kettle, including normal water boiling and pouring, water can be effectively prevented from overflowing from the gap between the spout and the kettle cover, and the overall sealing performance is enhanced, thereby reducing water leakage. On the other hand, during the water boiling process, when the water in the kettle is heated and boiled to generate a large amount of steam, the steam will generate a certain upward pressure on the kettle cover. At this time, the sealing element 23 on the outer side wall of the lower cover 2 can provide a certain friction and support force by closely fitting with the spout, thereby stabilizing the kettle cover and preventing the kettle cover from being pushed out of the spout due to the steam pressure, ensuring the safety and smooth progress of the water boiling process.

[0043] Referring to Figure 1 and Figure 2 The upper cover 1 and the lower cover 2 are ultrasonically connected, which can make the connection between the upper cover 1 and the lower cover 2 tight and the sealing stable, without the need for glue and other auxiliary materials, thereby ensuring good sealing, being clean and environmentally friendly, and being conducive to improving production efficiency.

[0044] Referring to Figure 1 The top of the upper cover 1 is provided with a handle 12, which facilitates the user to easily open and close the kettle cover when needed, and can make the operation of adding water, cleaning or boiling water more convenient and comfortable, thereby improving the convenience and comfort of the user operation.

[0045] The implementation principle of embodiment 1 is as follows:

[0046] In the normal boiling state, the steam generated in the kettle is smoothly discharged to the atmosphere through the communication groove 33 on the rotating block 32, the connecting pipe 22, the gas outlet hole 21 of the lower cover 2 and the exhaust hole 11 of the upper cover 1, ensuring the pressure balance in the kettle and guaranteeing the normal boiling process. At the same time, the silica gel ring seal 23 on the outer side wall of the lower cover 2 closely fits the spout of the kettle, preventing water from overflowing from the gap between the spout and the kettle cover, enhancing the overall sealing performance and reducing water leakage. In addition, when the water in the kettle is heated to produce a large amount of steam, which generates an upward pressure on the kettle cover, the silica gel ring seal 23 on the outer side wall of the lower cover 2 provides friction and support by closely fitting the spout, stabilizing the kettle cover and preventing it from being pushed out of the spout due to steam pressure, ensuring the safe and smooth progress of the boiling process.

[0047] When the electric kettle is tilted, the rotating block 32 automatically rotates based on the distribution of the center of gravity, so that the communication groove 33 is turned to the opposite direction of the tilting of the electric kettle and exceeds the horizontal plane, which is beneficial to prevent hot water from overflowing from the exhaust hole 11, reduce the risk of scalding safety accidents and provide safety protection for users. Even if the kettle cover is opened during the boiling process and then closed and tilted, since the communication groove 33, the gas outlet hole 21 and the exhaust hole 11 are always in communication, the safety hazard of the kettle cover being blown off due to the instantaneous increase in internal gas pressure caused by the internal thermal inertia heating of the kettle is avoided. If the electric kettle is tilted at a large angle or the internal water level is high, causing the liquid to possibly overflow and flow to the exhaust hole 11, the containing cavity 14 between the upper cover 1 and the lower cover 2 can accommodate the overflowing liquid, avoiding its direct overflow from the exhaust hole 11, further enhancing the anti-overflow effect of the kettle cover.

[0048] Embodiment 2

[0049] Referring to Figure 5 Embodiment 2 of the utility model discloses an electric kettle, including the kettle body 4 and being located at the spout of the kettle body 4 such as the anti-overflow kettle cover of tilting of embodiment 1, the side wall of the kettle body 4 is equipped with the handle 41 and the kettle mouth 42. In this embodiment 2, the combination of the kettle body 4 and the anti-overflow kettle cover of tilting makes the performance of the whole electric kettle significantly improved. When the electric kettle is in use, whether it is normal boiling or accidental tilting, the design features of the anti-overflow kettle cover of tilting in embodiment 1 can be fully embodied and play a role on the electric kettle.

[0050] The above only describes the preferred embodiments of the utility model and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
