[0002] At present, the treatment methods of tumors mainly include operation, radiotherapy, chemotherapy and the like, but all have corresponding shortcomings, such as side effects of radiotherapy and chemotherapy, and killing of normal cells. The use of electric field to treat tumors is also one of the current research frontiers, and tumor electric field treatment is a tumor treatment method for interfering with the mitosis process of tumor cells by a special electric field generating device to generate a low-intensity, medium-high frequency alternating electric field. Studies have shown that electric field treatment has remarkable effects in the treatment of diseases such as glioblastoma, non-small cell lung cancer and malignant pleural mesothelioma. The electric field applied by this method can affect the aggregation of tubulin, prevent spindle formation, inhibit the mitosis process, and induce apoptosis of cancer cells.

[0003] A common tumor electric field treatment device for tumor electric field treatment includes an electric field generating device and a pair of electrode patches. The electrode patches are attached to the body surface at the tissue region where the patient's lesion is located. The electric field generating device generates an alternating current signal and transmits the alternating current signal to the electrode patches to alternately generate an alternating electric field between each pair of electrode patches, thereby treating the tissue region where the patient's lesion is located. Chinese Utility Model Patent No. CN218391882U discloses an electric field generating device, which includes a housing and a battery compartment located in the housing. An installation groove is provided on the housing, and a liquid crystal display is installed in the installation groove. The liquid crystal display is connected with electrical functional components and a battery, and can display device information for user control. However, there is a gap between the display screen and the installation groove, and static electricity generated during static electricity detection or use of the liquid crystal display screen can flow to the liquid crystal display screen, causing the liquid crystal screen to malfunction or even be damaged.
