[0027] The present utility model will be described in detail below with reference to the accompanying drawings.

[0028] As Figures 1-3 shown, a housing connection structure includes a silicone housing 1. The silicone housing 1 is formed with a connection opening 11. A pole piece structure 2 is installed in the connection opening 11. The pole piece structure 2 includes an insulating sheet 21 and an electrode sheet 22 integrally formed on the insulating sheet 21. The shape of the connection opening 11 is adapted to the shape of the insulating sheet 21, and the opening area of the connection opening 11 is smaller than the area of the insulating sheet 21. Since the opening area of the connection opening 11 is smaller than the area of the insulating sheet 21, it is necessary to expand the connection opening 11 for the pole piece structure 2 to be inserted during installation. After the insulating sheet 21 is installed in the connection opening 11, due to the shrinkability of the silicone housing 1, the connection opening 11 will return to its original size, and the inner side wall of the connection opening 11 will closely adhere to the outer side wall of the insulating sheet 21, with basically no gaps generated, and it is not easy to accumulate dirt, which can increase the service life.

[0029] Preferably, the insulating sheet 21 is formed by processing a plastic material. The electrode sheet 22 is placed into the mold of an injection molding machine, and the injection molding machine integrally injects and forms, so that the insulating sheet 21 and the electrode sheet 22 formed in the injection molding machine are integrally formed to form an integral structure.

[0030] Preferably, the insulating sheet 21 can also be formed by processing a ceramic material.

[0031] Preferably, the electrode sheet 22 is formed by processing a metal conductive material.

[0032] Preferably, the electrode sheet 22 is formed by processing a stainless steel material.

[0033] The connection opening 11 includes an upper opening 12 and a lower opening 13. A support ring edge 14 that supports and contacts the bottom surface of the insulating sheet 21 is formed between the upper opening 12 and the lower opening 13. When the insulating sheet 21 is installed in the connection opening 11, the bottom surface of the insulating sheet 21 is attached to the support ring edge 14, and the side wall of the insulating sheet 21 is attached to the inner side wall of the upper opening 12, which can prevent the insulating sheet 21 from falling into the silicone housing 1 and prevent depression.

[0034] Furthermore, the shape of the upper opening 12 is adapted to the shape of the lower opening 13, and the area of the lower opening 13 is proportionally smaller than the area of the upper opening 12.

[0035] There is a first depth between the upper opening 12 and the lower opening 13, and the insulating sheet 21 has a first thickness, which is the same as the first depth. In this embodiment, when the insulating sheet 21 is installed into the connection opening 11, the front surface of the insulating sheet 21 is exactly flush with the surface of the silicone shell 1, so that the insulating sheet 21 and the silicone shell 1 form an integral structure, which can increase the stability of the overall structure and also enhance the aesthetics.

[0036] Furthermore, a glue layer 23 is provided between the inner side wall of the upper opening 12 and the outer side wall of the insulating sheet 21. The glue layer 23 bonds and connects the inner side wall of the upper opening 12 and the outer side wall of the insulating sheet 21. After the insulating sheet 21 is installed into the connection opening 11, the inner side wall of the connection opening 11 will closely adhere to the outer side wall of the insulating sheet 21. Due to the application of glue, the inner side wall of the connection opening 11 will further closely adhere to the outer side wall of the insulating sheet 21, further reducing the probability of generating gaps, so that the insulating sheet 21 and the silicone shell 1 form an integral structure, which can increase the stability of the overall structure.

[0037] Furthermore, the silicone shell 1 is a columnar structure, and both the insulating sheet 21 and the electrode sheet 22 are arc-shaped sheet structures, which can increase the comfort of holding after installation.

[0038] Furthermore, the curvature of the silicone shell 1 is respectively adapted to the curvatures of the insulating sheet 21 and the electrode sheet 22, which can further increase the comfort of holding after installation. When holding, the contact area between the electrode sheet 22 and the skin increases.

[0039] Furthermore, the insulating sheet 21 is formed with a through driving port 24, and the electrode sheet 22 is formed with a conductive block 25 that passes downward through the driving port 24. The conductive block 25 passes through the driving port 24 and is electrically connected to the electrode sheet 22 to supply power to the electrode sheet 22, and can generate electrical stimulation when contacting the skin.

[0040] A housing includes a silicone connection structure and also includes a plastic inner shell 15. The silicone shell 1 surrounds the surface of the plastic inner shell 15. The plastic inner shell 15 can support the silicone shell 1, and while maintaining soft contact during holding, it can prevent the silicone shell 1 from undergoing large deformations.

[0041] Furthermore, the plastic inner shell 15 is formed with an installation block 16 extending towards the connection opening 11, and the installation block 16 is formed with a connection groove 17. The insulating sheet 21 is formed with a connection block 18 connected to the connection groove 17; the installation block 16 will be inserted into the lower opening 13 of the connection opening 11. After the pole piece structure 2 is installed into the connection opening 11, the insulating sheet 21 is connected to the connection groove 17 of the installation block 16 through the connection block 18 to achieve installation. The insulating sheet 21 is simultaneously in contact and cooperation with the support ring edge 14 of the connection opening 11 and the upper opening 12 to achieve connection.

[0042] Furthermore, the plastic inner shell 15 is provided with a circuit structure, which is connected to the conductive block 25 and can supply power to the electrode sheet 22. The electrode sheet 22 generates a discharge effect, enabling electromyogram detection and neuromuscular electrical stimulation during holding to stimulate the pelvic floor muscles, resulting in a better muscle exercise effect.

[0043] Preferably, the number of connection openings 11 is more than two. According to requirements, the corresponding number of connection openings 11 can be set to install the corresponding number of pole piece structures 2.

[0044] It should be noted that the housing of this solution can be used in a biofeedback therapeutic apparatus or a biofeedback electrical stimulation therapeutic apparatus.

[0045] In summary, it can be seen that the present utility model has the above-mentioned excellent characteristics, enabling it to enhance the efficiency never achieved in the prior art during use and having practicality, thus becoming a product with extremely high practical value.

[0046] The above content is only the preferred embodiment of the present utility model.
