Description

Technical Field

[0001] The present application belongs to the field of medical device technology, and specifically relates to an electric field generating device. Background Art

[0002] At present, the main treatments for tumors include surgery, radiotherapy, chemotherapy, etc., but they all have corresponding disadvantages. For example, radiotherapy and chemotherapy can produce side effects and kill normal cells. Using electric fields to treat tumors is also one of the current research and development frontiers. Tumor Treating Fields (TTF) is a method of applying a low-intensity, medium-frequency alternating electric field to cancer cells, thereby interfering with the process of cancer cell mitosis, inhibiting cancer cell mitosis, and inducing cancer cell apoptosis, thereby achieving a therapeutic effect. Studies have shown that electric field therapy is effective 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 in dividing cancer cells, prevent the formation of spindles in dividing cancer cells, inhibit the mitotic process of cancer cells, and induce cancer cell apoptosis.

[0003] Internal components in the electric field generating device, such as the main board or the signal board, generate a lot of heat during operation. However, the heat dissipation performance of the electric field generating device is currently poor and cannot adapt to the various use environments of the electric field generating device, resulting in excessively high temperatures during operation of the electric field generating device, and even causing the electric field generating device to shut down for protection.

In addition, the present application also sets a display screen 161 on the first installation position, and fixes a buzzer 205 between the buzzer fixing part 206 and the display screen 161, so that the internal component structure of the electric field generating device is compact and the layout is more reasonable.

More specifically, the battery middle shell 31, the battery front shell 32 and the battery bottom shell 33 together constitute a battery housing, and the battery housing accommodates the battery cell 34 and a battery protection circuit. The battery cell 34 may be a lithium battery.

[0140] The battery middle shell 31 is axially movably disposed in the battery sleeve 204. That is, the entire battery 73 is movably disposed in the battery sleeve 204; the battery 73 is inserted into the battery sleeve 204 from the openings of the housing 1 and the battery sleeve 204.

In addition, the battery middle shell 31 is axially movably arranged in the battery sleeve 204, which can improve the convenience, aesthetics and safety of the battery 73.

[0145] In a specific embodiment, the battery 73 is a rechargeable battery.

[0146] In a specific embodiment, Figures 18a to 20 As shown, the locking portion 74 includes: a battery lock buckle 41 and a battery unlocking button 42. The battery lock buckle 41 includes a first elastic body 411 and a plurality of lock bodies 412. Each lock body 412 is arranged along the radial direction of the top receiving groove 311 of the battery middle shell 31, and the plurality of lock bodies 412 are arranged along the circumference of the top receiving groove 311. The first end of each lock body 412 is radially movable through the side wall of the top receiving groove 311 and the side wall of the battery front shell 32 and inserted into the side wall of the battery sleeve 204. The second end of each lock body 412 is radially movable in the top receiving groove 311, and the top of each lock body 412 is provided with a bevel groove 4121. The first end of the first elastic body 411 is arranged in the second end of one lock body 412, and the second end of the first elastic body 411 is arranged in the second end of another lock body 412 arranged opposite to the lock body 412.

[0147] The battery unlocking button 42 includes a button body 421 and a second elastic body 422. The top of the button body 421 is axially movably disposed in the third opening 321 of the battery front shell 32, and the bottom of the button body 421 is provided with a plurality of outwardly inclined oblique blocks 4211, the top of each oblique block 4211 is fixedly connected to the bottom of the button body 421, and the bottom of each oblique block 4211 can be slidably disposed in an inclined groove 4121. The bottom of the button body 421 is provided with a first accommodating cavity 4212, and the top accommodating groove 311 is provided with a second accommodating cavity 312. The first end of the second elastic body 422 is disposed in the first accommodating cavity 4212, and the second end of the second elastic body 422 is disposed in the second accommodating cavity 312.

[0148] In order to ensure that the button body 421 of the battery 73 can be pressed smoothly, the elastic modulus of the second elastic body 422 is smaller than the elastic modulus of the elastic part 72. It is understood that the elastic part 72 of the present invention may include multiple elastic bodies, and the multiple elastic bodies may be connected in parallel or in series or both in parallel and in series. The elastic modulus of the elastic part 72 refers to the elastic modulus of the multiple elastic bodies constituting the elastic part 72 as a whole.

[0149] When the battery 73 is inserted into the battery sleeve 204, the first ends of the multiple lock bodies 412 of the battery lock buckle 41 radially extend into the side wall of the battery sleeve 204, thereby fixing the battery 73, and the elastic part 72 is in a compressed state. When the battery unlocking button 42 is pressed, the first ends of the multiple lock bodies 412 of the battery lock buckle 41 radially retract inward and disengage from the side wall of the battery sleeve 204, and the elastic part 72 returns to its original position to eject the battery 73 axially.

[0150] Among them, when the battery 73 is inserted into the interior of the battery sleeve 204, the inclined surfaces of the first ends of the multiple lock bodies 412 are utilized, and the first ends of the multiple lock bodies 412 are first radially retracted to cause the first elastic body 411 to be compressed, and then the first ends of the multiple lock bodies 412 are radially extended out of the side walls of the top accommodating groove 311 and the side walls of the battery front shell 32 and inserted into the side walls of the battery sleeve 204, thereby fixing the battery 73 and the elastic part 72 is in a compressed state. The bottom slope of the inclined block 4211 fits with the corresponding slope of the inclined groove 4121. When the top of the button body 421 is pressed, the button body 421 moves downward, driving the bottom slopes of the multiple inclined blocks 4211 to slide downward along the slopes of the multiple inclined grooves 4121. The inclined block 4211 applies a horizontal force to the inclined block 4211, thereby driving the first ends of the multiple lock bodies 412 to retract radially (move in a direction away from the side wall of the battery sleeve 204) until the first ends of the multiple lock bodies 412 are separated from the groove of the battery sleeve 204, and the elastic part 72 is reset to eject the battery 73 axially, and the actual effect is achieved that the battery unlocking button 42 can drive the battery lock buckle 41 to unlock, but the battery lock buckle 41 cannot drive the battery unlocking button 42. At the same time, the elastic modulus of the second elastic body 422 is smaller than the elastic modulus of the elastic part 72.

The first end of the connecting part 4122 on each lock body 412 is fixedly connected to the first end of the lock body 412. The first end of each first elastic body 411 is arranged inside the second end of a connecting part 4122 of a lock body 412. The second end of each first elastic body 411 is arranged inside the second end of a connecting part 4122 of another lock body 412 arranged opposite to the connecting part 4122 of the lock body 412. A bevel groove 4121 is arranged on the top of each connecting part 4122. The number of inclined blocks 4211 is the same as the number of inclined grooves 4121. The bottom of each inclined block 4211 can be slidably arranged in the bevel groove 4121 of a connecting part 4122. Among them, by using multiple connecting parts 4122 and multiple first elastic bodies 411, it is possible to easily drive the first end of each lock body 412 to quickly move radially to extend and / or move back, and the stability and reliability are good.
