Technical Field

[0001] The present application relates to an electric field therapy apparatus and an electric field generating device thereof. Background Art

[0002] The electric field therapy device used for electric field therapy of tumors includes an electric field generating device and electrode patches arranged in pairs. The electrode patches are applied to the body surface of the patient's tissue area where the lesion is located. The electric field generating device provides 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 to treat the tissue area where the lesion is located.

[0003] Chinese utility model patent No. 202321710318.X discloses an electric field generating device, which includes a generator body with a battery compartment at the bottom and a battery assembly embedded in the battery compartment.

The housing 21 is also provided with a number of heat dissipation holes (not numbered) at corresponding positions to facilitate air flow and improve heat dissipation performance.

[0046] Combination Figure 3As shown, the electric field generating device 100 is arranged in a rectangular shape, and the housing 21 of the main body 20 includes an upper housing 211, a lower housing 212, and the aforementioned baffle plate 210 sandwiched between the upper housing 211 and the lower housing 212 and roughly in a "Z" shape. The upper housing 211 and the lower housing 212 are covered up and down to form a receiving space (not shown), and the baffle plate 210 is transversely arranged in the receiving space (not shown) and divides the receiving space (not shown) into a main control board compartment (not shown) for accommodating a main control board (not shown) and a battery compartment 213 for accommodating a battery assembly 10. An inlet 2131 connected to the battery compartment 213 is provided on one side of the housing 21. Specifically, an upper notch 2111 is provided on one side of the upper shell 211 and is recessed toward the top wall thereof. A lower notch 2121 is provided on the lower shell 212 corresponding to the upper notch 2111. When the upper shell 211 and the lower shell 212 are covered, the upper notch 2111 and the lower notch 2121 together form an entrance 2131. The battery assembly 10 is inserted into the battery compartment 213 from the entrance 2131. The main body 20 is provided with a plurality of side walls 2132 surrounding the entrance 2131. The plurality of side walls 2132 are jointly formed to enclose the aforementioned battery compartment 213. In this embodiment, the plurality of side walls 2132 are jointly formed by corresponding parts of the baffle plate 210 and corresponding parts of the lower shell 212. Specifically, the lower shell 212 is also provided with two baffles 2122 protruding from its bottom wall toward the upper shell 211 and respectively located on both sides of the lower notch 2121.

The baffle plate 210 includes a top plate (not labeled) sandwiched between the upper shell 211 and the lower shell 212 and placed horizontally, and a bent portion (not labeled) bent downward from the corresponding portion of the top plate (not labeled) and respectively abutting against the two baffles 2122 of the lower shell 212. The two baffles 2112 abut against the top plate (not labeled) of the baffle plate 210 in the vertical direction; in one direction of the horizontal plane, they respectively abut against the corresponding bent portions (not labeled) of the baffle plate 210 located on their respective outer sides; in the other direction of the horizontal plane, their respective ends abut against the corresponding portions of the upper shell 211 located in the battery compartment 213. The portion of the top plate (not labeled) of the baffle plate 210 located between the two bent portions 2101, the two baffles 2122 of the lower shell 212, and the bottom wall of the lower shell 212 located between the two baffles 2122 constitute the above-mentioned plurality of side walls 2132. The side walls 2132 together form a circle of steps 2133 facing the entrance 2131 at one end of the battery compartment 213 close to the entrance 2131 , which are used to abut against corresponding parts of the battery assembly 10 to play a role in installation positioning.

[0047] The side wall 2132 is provided with a latch hole 214, and the position of the latch hole 214 is closer to the entrance 2131 than the step 2133. The battery assembly 10 is provided with a latch tongue (unnumbered), and the latch hole 214 is used to snap-connect with the latch tongue (unnumbered) of the battery assembly 10 to lock the battery assembly 10 in the battery compartment 213. The specific position of the latch hole 214 corresponds to the position of the latch tongue (unnumbered) of the battery assembly 10. In this embodiment, the latch hole 214 is provided on the side wall 2132 of the main body 20 located on the top side of the battery compartment 213 (i.e., the top plate (unnumbered) of the baffle plate 210).

[0048] The electric field generating device 100 is placed flat, and the entrance 2131 is located on one side of the electric field generating device 100. The battery assembly 10 is inserted from the entrance 2131 and is placed flat in the battery compartment 213, so that the center of gravity of the electric field generating device 100 and the battery assembly 10 are both lower, which is more stable than the upright placement of the electric field generating device 100 and the battery assembly 10; at the same time, the tongue (unnumbered) of the battery assembly 10 is located on its top side, and the weight of the battery assembly 10 falls on the lower shell 212. Even if the battery assembly 10 shakes due to the movement of the electric field generating device 100, the tongue (unnumbered) is basically not affected by the gravity of the battery assembly 10, which can increase the service life of the tongue (unnumbered) and ensure stable power supply.

[0049] The lower shell 212 of the main body 20 is also provided with a plurality of anti-slip strips 215 on its bottom surface. The anti-slip strips 215 can be made of a soft material, which can be a silicone material, to prevent the electric field generating device 100 from being damaged by collision when the user is careless in placing the device. In addition, the friction between the electric field generating device 100 and the desktop can be increased to reduce the risk of the electric field generating device 100 accidentally slipping off the desktop. The lower shell 212 is provided with a groove (unnumbered) on its bottom surface, and the anti-slip strips 215 are located in the groove (unnumbered) and protrude from the bottom surface of the lower shell 212 to contact the desktop. The groove (unnumbered) can prevent the friction between the electric field generating device 100 and the desktop from causing the anti-slip strips 215 to shift when the electric field generating device 100 moves. Furthermore, the anti-slip strips 215 can be fixed to the bottom side of the lower shell 212 by adhesive (not shown).

[0050] The housing 21 is provided with a display device 216, an output port 217, and a signal indicator 218 on the other side thereof. The display device 216, the output port 217, and the signal indicator 218 are all electrically connected to the main control board (not shown). The display device 216 is a display screen that can be used to display treatment information such as the output electric field frequency and the treatment time. The output port 217 is used to connect a wire (not shown) to transmit the alternating electric signal generated by the main control board (not shown) to the electrode patch 300. The signal indicator 218 can be used to indicate the operating status of the electric field generating device 100, so as to more intuitively understand the operating status of the electric field generating device 100.

[0051] A number of guide ribs (not shown) may also be provided on the side wall 2132 of the outer shell 21 located in the battery compartment 213, and a number of guide grooves (not shown) are correspondingly provided on the battery assembly 10. The guide ribs (not shown) and the guide grooves (not shown) cooperate with each other to guide the battery assembly 10 to be quickly inserted into the battery compartment 213 and prevent the battery assembly 10 from shaking, so as to make the electrical connection between the battery assembly 10 and the electric field generating device 100 more stable, thereby improving the service life of the battery assembly 10.

In addition, the third guiding rib 4526 and the third avoidance groove 4527 can also provide a guiding function for the up and down movement, ensuring the stable up and down movement of the third locking part 452, and avoiding the skewness, dislocation, etc. during the movement. The top surface of the third guide rib 4526 of the third locking portion 452 can resist the third upper shell 41 upwards, preventing the third latch 450 from excessively protruding from the third upper shell 41. The third upper shell 41 is further provided with a fifth limiting rib 413 extending downwards on the inner side of the top wall near the third through hole 411. The fifth limiting rib 413 can increase the thickness of the third upper shell 41, preventing the third latch 450 from tilting out of the third through hole 411 when the third latch 450 is excessively retracted into the third through hole 411, so as to avoid the third latch 450 from being stretched and retracted unsmoothly.

[0092] The battery assembly 40 also includes a third notch 427 disposed at one end of the third lower shell 42. The third notch 427 is located at one end of the third lower shell 42 where the third locking device 45 is disposed. Specifically, the third notch 427 is formed by the bottom side of the third lower shell 42 being recessed toward the third front cavity 441. When the battery assembly 40 needs to release the snap connection with the main body 20, the operator can insert part of the fingers into the third notch 427 and use part of the fingers to move the third operating part 451, so that the battery assembly 40 can be pulled out while releasing the snap connection with the main body 20. The operation is more convenient and can be completed with only one hand.
