Technical Field

[0001] The utility model relates to the technical field of water tank drainage, in particular to a modular assembly structure of an electric heating rod of an electronic drainage valve. Background Art

[0002] The electronic drain valve is a device that controls the automatic discharge of water through electrical signals. In order to reduce the impact of low temperature environment on drainage, an electric heating rod is used to assist the use of the electronic drain valve.

[0003] In this regard, China has filed patent application number CN202320436727.9, which discloses a fuel cell drain tank for a counterbalanced forklift. The tank comprises a drain tank body and an FC controller. A water inlet is provided on one side of the drain tank body, connected to an external fuel cell. An exhaust pipe with a one-way valve is installed at the top of the drain tank body. A drain pipe with an electromagnetic drain valve is installed at the bottom of the drain tank body. An electric heater is installed within the drain tank body, and both the electromagnetic drain valve and the heater are connected to the FC controller. The FC controller is also connected to an integrated liquid level and water temperature sensor and a hydrogen concentration sensor, both of which are installed within the drain tank body. The FC controller controls the opening and closing of the electric heater and the electromagnetic drain valve on the drain tank body, providing heating and drainage. This facilitates effective thermal management of the water stored in the tank, enabling the drain tank to operate in low-temperature environments.

[0004] The drainage box is equipped with an electric heating rod to heat the water in the drainage box to prevent the water from freezing in a low temperature environment. However, the electric heating rod is installed on the side away from the drain pipe, and cannot quickly heat the water in the drain pipe, which will lead to untimely drainage. In addition, the electric heating rod is directly installed with the drainage box, which is inconvenient to disassemble and assemble.

[0005] Therefore, in order to solve the above problems, a modular assembly structure of an electric heating rod of an electronic drain valve is proposed. Utility Model Content
