[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

[0021] See alsoFigures 1-5 , the present utility model provides a technical solution: an energy-saving heater with a protection structure, including a housing 1. A fixing plate 2 is fixedly connected to the surface of the housing 1. An inner housing 3 is fixedly connected to the surface of the fixing plate 2. A jack 5 is provided on the surface of the fixing plate 2. A U-shaped heating screw rod 6 is arranged inside the inner housing 3. The ports of the U-shaped heating screw rod 6 are inserted into the inside of the jack 5. The number of the U-shaped heating screw rod 6 is three groups, which can further improve the heating efficiency of the heater. A water-permeable plate 4 is arranged at the bottom of the housing 1. The water-permeable plate 4 is fixedly connected to one end of the housing 1 and the inner housing 3. This facilitates the U-shaped heating screw rod 6 to directly contact with water and heat it. At the same time, it can also prevent large impurities that may exist in the water from entering the inside of the inner housing 3. Threaded rods 7 are fixedly connected to both ports of the U-shaped heating screw rod 6, which facilitates the fixed connection of the U-shaped heating screw rod 6 with an external connector. The housing 1 and the inner housing 3 are made of the same material. The housing 1 and the inner housing 3 are made of aluminum alloy material, which reduces the overall weight of the heater. At the same time, the aluminum alloy has good heat conduction effect, which is convenient for conducting the heat generated by the U-shaped heating screw rod 6. A voltage protector 8 is fixedly connected to the surface of the fixing plate 2. A clamping plate 9 is fixedly connected to the surface of the voltage protector 8. A U-shaped groove 10 is provided on the surface of the clamping plate 9, which can further protect the heater and prevent the heater from being damaged due to voltage changes.

[0022] Working principle: During use, when it is necessary to heat water, first place the heater in a container filled with water, and then insert the plug of the power cord of the heater into a socket. After the heater is powered on, the U-shaped heating screw rod 6 will continuously generate heat and heat the water. At the same time, the heat generated by the U-shaped heating screw rod 6 can also be conducted to the surroundings through the inner housing 3 and the housing 1 and heat the water, which realizes the protection of the U-shaped heating screw rod 6 and avoids accidental collision of the heater with an object during movement, resulting in damage to the U-shaped heating screw rod 6, which is beneficial to improving the service life of the heater. By setting the voltage protector 8, the heater can be further protected to prevent the heater from being damaged due to voltage changes.
