Split electric heater with protection sleeve

Abstract

The invention relates to the technical field of electric heating equipment, and discloses a split electric heater with a protection sleeve. The split electric heater comprises a cable seat, a heating bar is fixedly mounted at the bottom end of the cable seat, a protection shell is movably mounted outside the heating bar, the top of the protection shell and the cable seat are in clamped connection, and an inner container is fixedly connected in the protection shell through a connecting column. The protection shell and the top of the inner container are in seamless connection, a clearance is arranged between the protection shell and the inner container, an air pump is in clamped connection with the interior of the clearance, and clamping grooves matched with the air pump are formed in the protection shell and the upper portion of the inner wall of the inner container respectively. The split electric heater has the advantages that the situation of burnout or exploding and the like caused by waste heat is avoided; by means of split design, the cost is reduced, high practicality is achieved, the load of a user is reduced, the user does not need to worry that the heating bar is not located in the inner container, and cooling liquid can flow out due to external force factors, convenience during use is ensured, and practicality is further enhanced.

Description

technical field [0001] The invention relates to the technical field of electric heating equipment, in particular to a split electric heater with a protective cover. Background technique [0002] The electric heater is an internationally popular electric heating equipment, which is used to raise, keep warm and heat the flowing liquid or gaseous medium. When the heating medium passes through the heating chamber of the electric heater under pressure, it is uniformly taken away by the principle of fluid thermodynamics The huge heat generated by the electric heating element makes the temperature of the heated medium meet the user's process requirements. [0003] The water heating rod is a kind of electric heater. It is widely used because of its convenient use and low price. However, the safety of the water heating rod is often concerned by people. The existing water heating rod has a single structure, and there is no cooling structure for cooling, etc. To deal with it, users ne...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a split-type electric heater with a protective cover, which can prevent it from burning out or exploding due to waste heat. The split-type design can ensure the safety of the water heating rod, It can also realize the interchange between the water heating rod and the protective case, and there is no need to replace the protective case after the water heating rod is damaged, and vice versa, which saves cost and has strong practicability, and at the same time prevents users from forgetting to prepare water and other cooling liquids, which may cause burns. In the event of safety hazards such as water rod burning or explosion, the burden on users is reduced, and there is no need to worry about the cooling liquid flowing out due to external factors when the heating rod is not in the inner tank, which ensures the convenience of use and further increases practicability. Some water heaters have a single structure, and there is no cooling structure for cooling and other treatments. Users need to prepare water and other cooling liquids for cooling every time they use it. The operation is cumbersome, and users often forget to prepare water and turn the boiler The water stick is placed in the air, which will cause safety hazards such as burning or explosion of the boiling water stick, which makes users less and less problematic
