The invention relates to the technical field of electric kettles, in particular to an electric kettle with a cover that can be automatically opened at a constant speed.
An electric kettle is a fast, safe and convenient household appliance. It usually has functions such as intelligent steam induction temperature control, automatic power off after boiling, and dry-boiling prevention. With the improvement of living standards, people's experience requirements for household appliances is getting higher and higher. The current method of opening the lid of the kettle is generally pressing the button, the lid rotates through the shaft at the handle of the kettle, and the position of the lid close to the spout of the kettle begins to lift up to achieve the purpose of opening the lid. However, this kind of lid opening method has the following issues: 1. The buttons are generally on the top of the cover, and it is easy to be scalded by steam when opening the cover; 2. Due to structural reasons, when the cover is opened too fast, the impact force is big, and the high-temperature water droplets condensed on the bottom of the cover are easy to pop out. It is easy to be burnt when water splashed on the human body. Therefore, an electric kettle with automatic opening cover at a constant speed is provided.
The purpose of the present this invention is to solve the shortcoming of existing technology, provide a kind of electric kettle that automatically opens the lid at a constant speed.
In order to achieve the above object, the present invention adopts the following technical solution: an electric kettle with a constant speed and automatic opening cover, comprising an electric kettle body, an upper cover is designed on the upper end of the electric kettle body, and a lower end is fixedly installed on the lower end of the upper cover. cover, the lower end of the lower cover is fixedly connected with a guide rail sleeve, the inner surface of the electric kettle body is fixed with a guide rail, the upper surface of the electric kettle body is provided with a button, and the inner surface of the electric kettle body is provided with a connecting Rod and ejector rod, the outer surfaces of the connecting rod and the ejector rod are both sleeved with springs, the inner surface of the electric kettle body is fixed with a fixed plate, and the lower end of the fixed plate is rotatably connected with a cord storage box. The outer surface of the cord storage box is covered with a pull wire, the surface of the cord storage box is provided with a constant force spring, and the surface of the cord storage box is provided with a damper.
In order to install the damper, the invention is improved as follows: the surface of the cord storage box is fixedly installed with a damper interface.
In order to pull the guide rail cover, the present invention improvement is as following: one or more pull wire rings are fixedly connected to the inner surface of the electric kettle body, one end of the pull wire is fixedly connected to the pull wire ring, and the other end of the pull wire is fixed to the guide rail sleeve.
In order to improve the strength of the pull wire, the present invention improved pull wire material to thin stainless steel wire, nylon wire or flexible wire body with high tensile strength, and the damper can also be a gear box structure.
In order to scrape off the high-temperature water droplets on the lower cover, the present invention is improved as follows: the inner surface of the electric kettle body is fixedly connected with a silicone ring, and the upper end of the silicone ring is provided with a thin rib.
In order to make the push rod move downward, the present invention is improved as follows: one side of the connecting rod is provided with a slope a, and the lower end of the push rod is provided with a slope b.
In order to make the kettle cover move along the guide rail, after improved the present invention, the guide rail is smoothly connected with the guide rail sleeve.
In the present invention, in order to solve the above problems, using a constant force spring, a wire cord storage box, a pull wire and a damper. When the cover is closed, the pull wire will pull the constant force spring to move. Except for the fixed plate, other components will rotate together with the pull wire until the top rod slide into the groove of the lower cover. Press the button when opening the cover, the spring force will pull the guide rail sleeve fixed on the guide rail, and then automatically complete the opening action. Among them, the constant force spring can provide equally power and use together with the damper to achieve a state of equal elastic force, equal and stable movement process; With double guide rail structure to ensure that the lid will not shake or swing during movement. Open the lid during the process by using silicone ring and thin ribs, the high-temperature water droplets on the lower cover are scraped off, so that the water droplets will not fall off and burn your hands, so that with a simple structure, the speed of opening the cover is consistent, there is no abnormal sound, and the purpose of preventing burns is achieved.

In order to understand the above objects, features and advantages of the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings and embodiment. It should be noted that, in the case of no conflict, the embodiment of the present application and the features in the embodiment can be combined with each other.
In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways than those described here. Therefore, the present invention is not limited to the specific embodiment disclosed in the description below.

Working principle: when in use, the constant force spring 13 provides power, the damper 14 ensures a relatively uniform movement, the two-way guide rail 5 ensures uniform force during the movement of the lid, and the pull wire 12 is designed to ensure the maximum stroke. When closing the lid, A force is applied from the outside to close the lid manually, and the lid moves toward the spout through the guide rail cover 4. Since the guide rail cover 4 is connected to the pull wire 12, the guide rail cover 4 pulls the pull wire 12, and the constant force spring 13 is closed. After the cover is in place, the lower cover 3 is close The push rod 8 is snapped into the groove at the handle position, and the cover is closed at this time. When the cover is to be opened, the button 6 is pressed first, the connecting rod 7 is pressed by the button 6 to move to the left, and the rightmost end of the connecting rod 7 pushes Hold the lower end of the ejector rod 8, and use the inclined plane a and the inclined plane b to move the ejector rod 8 downward, and the groove in the lower cover 3 is disengaged from the ejector rod 8. At this time, the constant force spring 13 is naturally relaxed and pulled by the pull wire 12. The guide rail cover 4 on the cover approaches the handle direction, and the guide rail cover 4 then slides on the guide rail 5. After the guide rail cover 4 moved to the end of the guide rail 5, the lid stopped moving, and now the uncapping action was completed.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention to other forms.
