Description

Technical Field

[0001] The utility model belongs to the field of hot water kettle structures, in particular to a tipping and overflow prevention mechanism for a hot water kettle. Background Art

[0002] A kettle is a device that heats liquid through an electric heating wire. Most kettles use stainless steel as the body, and the kettle is usually separated from the power base.

[0003] When the existing hot water kettle is used, liquid is added into the kettle, and then the kettle body is placed on a power base and powered on to heat the liquid in the kettle.

[0004] When the existing hot water kettle is used to pour water, hot steam is easy to leak from the kettle cover, causing scalding of the user's hands. At the same time, when the hot water kettle is used, hot water will be sprayed out along with the steam, causing leakage of the hot water.

[0005] To this end, the utility model provides a tipping and overflow prevention mechanism for a hot water kettle. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the utility model to solve its technical problems is as follows: the tipping and overflow prevention mechanism of a hot water kettle described in the utility model comprises a first kettle body; a spout is arranged on the top of the first kettle body; a first kettle lid lower cover is installed on the top of the first kettle body; a water outlet switch spring is fixedly connected to the top of the first kettle lid lower cover; the top of the water outlet switch spring is connected to the water outlet switch; a rotating shaft is rotatably connected to the middle part of the water outlet switch; the end of the rotating shaft is rotatably matched with the top of the first kettle lid lower cover; a water outlet rod is slidably connected to the top of the first kettle lid lower cover; the water outlet rod is connected to the end of the water outlet switch; a water outlet rod sealing ring is fixedly connected to the bottom of the water outlet rod; a water outlet rod spring is sleeved on the middle part of the water outlet rod; one end of the water outlet rod spring is connected to the end of the water outlet rod, and the other end is connected to the first kettle lid lower cover; the first kettle lid A first pot lid sealing ring is installed on the side wall of the lower cover; a water outlet hole is opened in the middle of the lower cover of the first pot lid; the position of the water outlet rod sealing ring corresponds to the water outlet hole; a first pot lid is installed on the top of the lower cover of the first pot lid; a first lock is slidably connected to the middle of the first pot lid; a lock spring is installed between the first lock and the first pot lid; a buckle position is installed on the top of the first pot body; the end of the first lock cooperates with the buckle position; a first switch button is installed on the handle of the first pot body; a steam inlet is opened on the top of the first pot body; a first gravity block is arranged inside the steam inlet; a temperature control switch is installed inside the first pot body at the bottom of the first switch button; the first pot body is opened at the top; a pot body sealing step is fixedly connected to the middle of the first pot body; the pot body sealing step is located at the bottom of the lower cover of the first pot lid. When in use, cold water is injected into the first kettle body, and then the temperature control switch can be controlled by pressing the first switch button. At this time, the first kettle body can heat the liquid inside. When the temperature of the liquid inside the first kettle body gradually increases, at this time, because the first gravity block is placed inside the steam inlet, and at the same time, because there are reinforcing ribs inside the steam inlet to support the first gravity block, steam will be discharged through the steam inlet to the inside of the first kettle body shell and contact with the first kettle body at the same time. At the same time, part of the steam will be discharged from the top of the first kettle body. When the temperature reaches the set temperature, the temperature control switch can control the first kettle. The power to the first kettle body is cut off, so that the first kettle body stops boiling water; then the first kettle body can be tilted, and the water outlet switch is pressed at the same time, so that the water outlet switch controls the water outlet rod to release the water outlet hole on the top of the first kettle body, so that the liquid inside the first kettle body flows out from the spout. In the process of tilting the first kettle body, the first gravity block can move inside the steam inlet under the influence of gravity to block the top of the first kettle body. At this time, when tilting, no liquid will overflow from there, reducing the problem of water overflowing from other positions when the spout is normally discharging water, thereby improving the safety of the first kettle body when in use and reducing the waste of water resources.

[0008] Preferably, the boundary of the first gravity block is chamfered, wherein the chamfered position is located at the bottom of the first gravity block.

[0012] Preferably, the buckle position is elastically arranged; the bottom opening of the sealing step of the kettle body is smaller than the bottom diameter of the lower cover of the first kettle lid.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The utility model discloses a tipping and overflow prevention mechanism for a hot water kettle. By adding a movable gravity block at the exhaust port, the kettle body can be tilted so that the gravity block can be blocked at the exhaust port to prevent the hot water inside the hot water kettle from overflowing from the exhaust port.

[0015] 2. The tipping prevention mechanism of the hot water kettle described in the utility model can detect the exhaust temperature synchronously when the kettle body is exhausting steam normally by connecting the steam inlet, the exhaust port and the temperature control switch.
