[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] Low-frequency current is a form of physical energy that can directly act on muscles and nerves, inducing muscle contraction and relaxation to achieve effects such as relaxation, enhanced muscle strength, or accelerated recovery. Based on this, embodiments of this invention propose an electrical stimulation device that uses low-frequency current to stimulate the human body, thereby achieving purposes including, but not limited to, massaging muscles and promoting blood flow.

[0033] Referring to Figures 1-8, the electrostimulation device provided in the embodiments of this utility model includes a first substrate 1, a first electrode assembly 3, a second electrode assembly 4, and a power supply assembly 5. Both the first electrode assembly 3 and the second electrode assembly 4 are electrically connected to the power supply assembly 5. The power supply assembly 5 provides power to the first electrode assembly 3 and the second electrode assembly 4, thereby generating a stimulating current when either the first electrode assembly 3 or the second electrode assembly 4 contacts the human body. The first electrode assembly 3 is disposed on the first substrate 1 and includes a first left electrode 31 and a first right electrode 32 spaced apart in a left-right direction. The first left electrode 31 and the first right electrode 32 are respectively connected to the input and output terminals of the power supply assembly 5, i.e., the polarities of the first left electrode 31 and the first right electrode 32 are opposite. The second electrode assembly 4 includes a second left electrode 41 and a second right electrode 42. The second left electrode 41 is disposed on the left side of the first substrate 1, and the second right electrode 42 is disposed on the right side of the first substrate 1. The second left electrode 41 and the second right electrode 42 are respectively connected to the input and output terminals of the power supply assembly 5, i.e., the polarities of the second left electrode 41 and the second right electrode 42 are opposite. The first electrode assembly 3 and the second electrode assembly 4 act on different areas of the human body. To accommodate the different electrical stimulation needs of different areas of the same user, the stimulation current generated by the first electrode assembly 3 and the second electrode assembly 4 can be the same or different. Therefore, the power supply assembly 5 includes a first output terminal and a second output terminal. The first left electrode 31 and the second left electrode 41 are respectively connected to the first output terminal and the second output terminal of the power supply assembly 5. The first right electrode 32 and the second right electrode 42 are connected to the input terminal of the power supply assembly 5, or the first right electrode 32 and the second right electrode 42 are respectively connected to the first output terminal and the second output terminal of the power supply assembly 5. The first left electrode 31 and the second left electrode 41 are connected to the input terminal of the power supply assembly 5. That is, in the left-right direction, the electrodes located on the same side of the human body have the same polarity. It is worth emphasizing that "left and right" in the above refers to the left and right sides of the human body.

[0034] The aforementioned electrostimulation device utilizes the stimulation current generated by the first electrode assembly 3 and the second electrode assembly 4 to stimulate different areas of the human body. For example, the first electrode assembly 3 acts on the gluteus maximus muscle, and the second electrode assembly 4 acts on the gluteus medius muscle; or the first electrode assembly 3 acts on the foot, and the second electrode assembly 4 acts on the knee; or the first electrode assembly 3 acts on the gluteus maximus muscle, and the second electrode assembly 4 acts on the lower back. Compared to other massage products that act on the surface of the human body, it can provide an effective massage with better results. Moreover, the current interference generated by the first electrode assembly 3 and the second electrode assembly 4 is small, which can adapt to the different levels of receptivity to electrical stimulation in different areas of the human body or provide different massage effects. It is understood that, depending on the increase in the area of ​​action, the electrostimulation device may also include a third electrode assembly, a fourth electrode assembly, etc. Different electrode assemblies located on the same side with the same electrode polarity and connected to different output terminals of the power supply assembly 5 should all be considered to fall within the protection scope of this utility model.

[0035] In one embodiment, the electrical stimulation device is primarily used on the buttocks of the human body. Specifically, the first electrode assembly 3 acts on the gluteus maximus muscle, and the second electrode assembly 4 acts on the gluteus medius muscle. The first left electrode 31 and the first right electrode 32 are positioned based on the distance between the left and right sides of the gluteus maximus muscles, and the first base 1 can be a flexible pad or a seat.

[0036] In one embodiment, the electrical stimulation device is applied in a bathtub. Referring to Figure 2, in order to prevent water from entering the power supply component 5, the first base 1 includes a face cover 11 and a bottom cover 12. Both the face cover 11 and the bottom cover 12 are made of waterproof material. The first electrode component 3 is disposed on the face cover 11. The bottom cover 12 is connected to the face cover 11 by means not limited to adhesive bonding and surrounds the face cover 11 to form an installation cavity. The power supply component 5 is located in the installation cavity.

[0037] Specifically, referring to Figure 4, the power supply component 5 includes an upper shell 55, a lower shell 56, a control circuit board 51, and a battery 52. ​​The upper shell 55 and the lower shell 56 enclose a control cavity. The control circuit board 51 and the battery 52 are both located within the control cavity and are interconnected. The first output terminal, the second output terminal, and the input terminal of the power supply component 5 are all located on the control circuit board 51. Specifically, to achieve reusability of the battery 52, the power supply component 5 also includes a charging interface provided on the faceplate 11. The charging interface has a charging contact 57 inside, which is electrically connected to the control circuit board 51. A plug is detachably provided at the charging interface to prevent water from entering. At the same time, to improve the user experience, the first left electrode 31 and the first right electrode 32 are both made of flexible materials such as conductive silicone, and the first left electrode 31 and the first right electrode 32 are fixed to the faceplate 11 with adhesive.

[0038] The power supply component 5 also includes control keys electrically connected to the control circuit board 51 for adjusting gear positions and controlling on / off states. Specifically, the control keys are pushbuttons, including but not limited to a power switch and a gear adjustment key. In one embodiment, the control circuit board 51 is provided with a sequential logic circuit to switch the state of the first output terminal and the second output terminal by pressing the power switch. The sequential logic circuit is prior art and will not be described in detail here.

[0039] More specifically, the gear adjustment keys include a first gear adjustment key and a second gear adjustment key, wherein the first gear adjustment key is used to increase the gear level and the second gear adjustment key is used to decrease the gear level. When using the above-mentioned electrical stimulation device, press and hold the power button to turn it on and off. After powering on, the gear levels of the first and second output terminals can be adjusted synchronously by default. Press the first gear adjustment key to increase the gear level and press the second gear adjustment key to decrease the gear level. Press the power button once to switch to the gear level of the output terminal connected to the first electrode assembly 3. Press the power button twice to switch to the gear level of the output terminal connected to the second electrode assembly 4.

[0040] Referring again to Figure 4, the power supply component 5 also includes a light guide post 53 mounted on the control circuit board 51 and a vibration motor 54 electrically connected to the control circuit board 51. The light guide post 53 covers the indicator lights and extends through the upper shell 55, guiding the light from the indicator lights on the control circuit board 51 to the outside of the power supply component 5. Depending on the operation, the color of the same indicator light changes or different indicator lights illuminate. For example, the indicator lights include white, green, and blue lights. A white light illuminates when the power is on, a short press switches to a green light, and another short press switches to a blue light. Different colored indicator lights represent the adjustable levels of different output terminals of the power supply component 5. The vibration motor 54 vibrates with each press of the control button. When the power button is pressed for a long time, the vibration motor 54 vibrates twice to distinguish it from switching the adjustable output terminal.

[0041] In one embodiment, both the second left electrode 41 and the second right electrode 42 are electrically connected to the control circuit board 51 via wires 7. This allows for adjustable positioning between the second substrate 2 and the first substrate 1, while maintaining a greater distance between the second electrode assembly 4 and the first electrode assembly 3. This enables the first electrode assembly 3 and the second electrode assembly 4 to act on different areas of the human body at a certain distance when using the electrical stimulation device. Furthermore, the electrical stimulation device also includes the second substrate 2, which can be a flexible pad. The second substrate 2 is provided on both the left and right sides of the first substrate 1. The second left electrode 41 is located on the second substrate 2 on the left side of the first substrate 1, and the second right electrode 42 is located on the second substrate 2 on the right side of the first substrate 1. Specifically, a connecting sleeve 8 is provided between the first substrate 1 and the second substrate 2. The connecting sleeve 8 is detachably connected to the first substrate 1 and / or the second substrate 2, thereby achieving a detachable connection between the first substrate 1 and the second substrate 2. This allows the second substrate 2 to be removed from the first substrate 1 when the second electrode assembly 4 is not needed, making the application more flexible. It should be emphasized that the wires 7 used for electrically connecting the power supply assembly 5 and the second electrode assembly 4 are also detachably connected to the control circuit board 51 through an interface located at the connection between the connecting sleeve 8 and the first base 1.

[0042] To ensure that the second left electrode 41 and the second right electrode 42 remain in contact with the human body, the connecting sleeve 8 is flexible, bendable, and can remain in a bent state. When the connecting sleeve 8 remains bent, the second left electrode 41 and the second right electrode 42 remain in contact with the human body. Specifically, the wire 7 is disposed within the connecting sleeve 8.

[0043] More specifically, the connecting sleeve 8 is detachably connected to the first base 1 using methods including but not limited to plugging or snap-fitting. This allows the connecting sleeve 8 to be removed from the first base 1 along with the second base 2, avoiding any foreign body sensation. To prevent water from seeping into the mounting cavity from the connection between the connecting sleeve 8 and the first base 1, a sealing ring 9 is fitted onto the connecting sleeve 8. The sealing ring 9 abuts against the connecting sleeve 8 and the first base 1, achieving a seal.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
