Description

[Technical field]

[0001] The present invention relates to the technical field of kettles, and in particular to a structure for preventing a kettle cover from tipping over. [Background technology]

[0002] Currently, electric kettle products on the market often use an anti-overflow valve to control the opening and closing of the steam passage, and the spout is controlled by a button switch that controls the on / off of the circuit. The two are combined together to control the operating state of the anti-overflow valve, thereby preventing the water in the kettle body from overflowing when the kettle falls over.

[0003] Chinese Patent CN218978600U discloses an electric kettle that prevents overflow even if it is tipped over, in which an outlet is provided at the bottom of one side of the kettle body, a handle is provided on the other side of the kettle body, a first valve is provided at the outlet, and a spout is connected to the outlet. A cover for closing an opening of the kettle body is provided with a steam outlet, a first steam outlet passage, a second steam outlet passage and two steam inlets, one end of the first steam outlet passage and the second steam outlet passage are both connected to the steam outlet, the other end of the first steam outlet passage is connected to one of the steam inlets, and the other end of the second steam outlet passage is connected to the other of the steam inlets, the two steam inlets are provided symmetrically and are respectively located on both sides of a line connecting the handle and the steam outlets, and an anti-overflow valve is used to control the opening and closing of the first steam outlet passage and the steam outlet, and the opening and closing of the second steam outlet passage and the steam outlet.

[0004] Conventional electric kettles that prevent overflow even when knocked over have a very complicated overall structure and are expensive, and their manufacturing and installation are complicated and cumbersome, resulting in an extremely high defect rate during manufacturing. In addition, the conditions for triggering the operation of the overflow prevention valve are complicated, and in special cases the trigger conditions for the overflow prevention valve cannot be met simultaneously, making it impossible to ensure that the water in the kettle body is prevented from overflowing when the kettle is knocked over.

[0005] Therefore, the prior art requires further improvement and development. Summary of the Invention [Problem to be solved by the invention]

[0006] SUMMARY OF THE PRESENT DISCLOSURE The present invention aims to provide a tip-over prevention kettle cover structure that has a reasonable structure, a compact layout, and is safe to use, in response to the deficiencies of the prior art. [Means for solving the problem]

[0007] To achieve the above objectives, the present invention uses the following technical solutions:

[0008] The tip-over prevention kettle cover structure of the present invention includes a cover and a kettle body, the cover is provided with an operating assembly, a passage and a sealing baffle, the cover covers the opening of the kettle body, the lower end mouth of the passage is connected to the cavity of the kettle body, the upper end mouth of the passage is provided corresponding to the spout of the kettle body, the operating assembly is transmission-connected to the sealing baffle, so that the sealing baffle is provided to be fitted with the lower end mouth of the passage, and the operating assembly or the sealing baffle is provided with a floating counterweight. The cover covers the opening of the kettle body and communicates with the cavity of the kettle body through a built-in passage, and is used to pour water in the kettle body through the passage and out of the spout. The sealing baffle is installed under the cover and corresponds to the lower end mouth of the passage, and the operating assembly has an upward driving force on the sealing baffle, so that the sealing baffle can close the passage. Alternatively, the operating assembly can move the sealing baffle downward under the action of an external force to open the passage, so that the water in the kettle body can be normally poured out from the spout through the passage.

[0009] Furthermore, when the kettle body is placed vertically when boiling water, the floating counterweight applies gravity to the operating assembly or the sealing baffle, overcoming the driving force provided by the operating assembly, and causing the sealing baffle to sink slightly, thereby opening the lower end mouth of the passage, and the steam pressure generated when the kettle body boils water can be discharged outside through the passage, preventing safety issues such as the lid flying off due to the internal pressure of the kettle body being too large.

[0010] In particular, when the kettle body is in an abnormal tilting state, the gravity of the floating counterweight is still vertically downward, but the gravity of the floating counterweight is no longer applied to the operating assembly or the sealing baffle, and the driving force of the operating assembly drives the sealing baffle to seal the lower end mouth of the passage and prevent the water in the kettle body from flowing out, thereby achieving the purpose of preventing tipping, and the overall structure is compact and reasonable, which can effectively improve the usage experience of the kettle product.

[0011] According to the above embodiment, the cover includes a bracket and a bottom plate, the bottom plate is disposed below the bracket and fixedly connected thereto, the bracket is attached to the kettle body to allow the bottom plate to cover the opening of the kettle body, the passage is disposed between the bracket and the bottom plate, the lower end of the passage is connected to the cavity of the kettle body by penetrating the bottom plate, the operating assembly is inserted into the passage, the lower end of the operating assembly is fitted and connected to the sealing baffle, and a button is provided on the bracket, which is transmission-connected to the upper end of the operating assembly. The bracket is the main body structure of the cover, the bracket is assembled to the kettle body to correspond to the bottom plate and the opening, and a seal ring is provided between the bottom plate and the opening. A passage is formed between the bottom plate and the bracket to connect the cavity of the kettle body to the outside, the operating assembly is attached to the bracket, the lower end of the operating assembly is connected to the sealing baffle, the operating assembly provides an upward acting force to the sealing baffle, and the sealing baffle can cover the lower end of the passage, thereby achieving the purpose of blocking the passage. Furthermore, the button can move the sealing assembly downwards by the operating assembly, so that the sealing baffle opens the passage. As can be seen, a panel is further provided on the bracket, and the button is movably mounted on the panel, and the button can be transmission-connected to the operating assembly, usually by a lever-type structure.

[0012] According to the above aspect, the operating assembly includes an operating rod and a first spring, a guide base is provided on a bracket, the operating rod is inserted into the guide base so as to be vertically movable, a button is fitted and connected to the upper end of the operating rod, the lower end of the operating rod is fixedly connected to the sealing baffle, a fixed piece is provided on the operating rod, the first spring is fitted on the operating rod, the lower end of the first spring abuts on the guide base, and the upper end of the first spring abuts on the fixed piece. The guide base is molded and installed on the bracket, the guide base has a hollow structure, the operating rod is inserted into the guide base and moves up and down along it, the fixed piece is fixedly installed on the middle upper part of the operating rod, the upper end of the first spring abuts on the fixed piece, and the first spring applies an upward elastic energy to the fixed piece, so that the operating rod always drives the sealing baffle to approach the lower end mouth of the passage. Furthermore, the button is transmission-connected to the operating rod, and overcomes the acting force of the first spring to move the sealing baffle downward to open the passage.

[0013] According to the above embodiment, the floating counterweight is movably installed in the guide base, the floating counterweight is provided with a through hole, the upper end of the operating rod is movably connected to the floating counterweight by passing through the through hole, and the floating counterweight presses against the fixed piece. The floating counterweight is movable in the guide base, and when the kettle body is normally upright, the floating counterweight presses against the fixed piece, and the gravity of the floating counterweight is vertically downward, which overcomes the acting force of the first spring, moving the sealing baffle away from the lower end mouth of the passage, realizing the mouth of the passage to be constantly open, and preventing the problem of excessive internal pressure when the kettle is boiling water, and the passage plays the role of release at this time. When the kettle body falls over, the gravity of the floating counterweight is no longer directed toward the fixed piece, and the first spring is released, which drives the sealing baffle to cover the lower end mouth of the passage, preventing the water in the kettle body from flowing out.

[0014] According to the above embodiment, the inner diameter of the guide base is larger than the outer diameter of the floating counterweight, and the diameter of the through hole of the floating counterweight is larger than the diameter of the operating rod. Preferably, there is a gap fit between the outer edge surface of the floating counterweight and the inner wall of the guide base, and similarly, there is a gap fit between the operating rod and the through hole, and the floating counterweight can apply a gravity force to the fixed piece to drive the sealing baffle to open the passage only under the normal state in which the kettle body is standing. Preferably, the inner wall of the guide base is provided with a step portion or a conical surface structure, and the floating counterweight can abut against the step portion or the conical surface structure to form a limit fit, preventing the first spring from being excessively compressed to affect the sensitivity of the structure, and ensuring a reasonable gap between the sealing baffle and the lower end mouth of the passage.

[0015] According to the above embodiment, the floating counterweight is movably installed between the bracket and the sealing baffle, the lower end of the operating rod is movably connected to the floating counterweight by passing through the through hole, and the floating counterweight presses against the sealing baffle. The floating counterweight may be attached to the sealing baffle, and the floating counterweight can move up and down between the bracket and the sealing baffle. Furthermore, when the kettle body falls over, the direction of gravity caused by the floating counterweight also changes, and the operating assembly can drive the sealing baffle to close the lower end mouth of the passage.

[0016] According to the above embodiment, the sealing baffle is provided with a release sheet, the release sheet is provided with a release hole, the release hole is connected to the sealing baffle to communicate with the cavity of the kettle body and the passage, a release plug and a second spring are provided in the release hole, the second spring is connected to the release plug and the release sheet respectively, thereby driving the lower end of the release plug to close the release hole, and the floating counterweight is movably installed in the release hole, and the floating counterweight presses against the upper end of the release plug. The above operating assembly applies a force to the sealing baffle under normal conditions to normally close the sealing baffle and the passage. Thus, the floating counterweight applies gravity to the release plug to overcome the force of the second spring, and the release plug opens the release hole, preventing the steam pressure in the kettle body from being too high. When the kettle body falls over, the gravity direction of the floating counterweight changes, and the second spring drives the release plug to close the release hole, preventing the water in the kettle body from leaking through the release hole and the passage.

[0017] According to the above aspect, anti-detachment covers are provided on both the upper end opening of the guide base and the upper end opening of the release sheet, and the anti-detachment covers are used to seal the guide base and the upper end opening of the release hole, thereby sealing the floating counterweight inside both and preventing it from detaching.

[0018] In the anti-tipping kettle cover structure of the present invention, when the kettle body is in an abnormal tipping state, the gravity of the floating counterweight is still directed vertically downward, but the gravity of the floating counterweight is no longer applied to the moving assembly or the sealing baffle, and the driving force of the moving assembly drives the sealing baffle to seal the lower end mouth of the passage and prevent the water in the kettle body from flowing out, thereby achieving the purpose of preventing tipping, and the overall structure is compact and reasonable, which can effectively improve the usage experience of the kettle product.
