Description

Technical Field

[0001] This application relates to the field of electrotherapy device technology, specifically to a portable intelligent electrotherapy device. Background Technology

[0002] Electrotherapy is a therapeutic instrument that uses electric current to stimulate acupoints or diseased areas of the human body to achieve the purpose of treating diseases, relieving pain, and promoting blood circulation. It combines the advantages of acupuncture and acupressure in stimulating acupoints, clearing meridians, regulating yin and yang, and balancing internal organs, while avoiding the disadvantages of acupuncture such as invasiveness and pain. It has significant therapeutic and health care effects.

[0003] Existing portable electrotherapy devices typically include a main unit with multiple wires that can be connected to. Each wire has an electrode pad attached to its end. The electrode pads are then placed on the surface of acupoints or affected areas. The main unit transmits electrotherapy pulses to the body through the wires and electrode pads, thus performing electrotherapy. Multiple wires and electrode pads can simultaneously treat multiple acupoints. However, existing electrotherapy devices are not convenient for proper wire storage, and the wires are prone to tangling and knotting, which affects their practicality. Therefore, this application proposes a portable intelligent electrotherapy device. Utility Model Content

[0004] The purpose of this application is to provide a portable intelligent electrotherapy device in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] The take-up shell has a guide rod that rotates through it. The guide rod has a through groove, and the take-up shell has a through slot. A USB connector for plugging into a USB interface is provided on one side of the take-up shell. A wire is connected to the USB connector via an electric slip ring. The free end of the wire moves through the through groove and the through slot in sequence and is connected to an electrode plate. The take-up shell is provided with an adjustment mechanism for adjusting the rotation of the guide rod.

[0008] Furthermore, the adjustment mechanism includes baffles fixed at both ends of the guide rod, and both ends of the guide rod are connected to the inner wall of the winding shell by a spiral spring. The winding shell is provided with a fixing member for fixing the wire.

[0009] Furthermore, the fixing member includes a lower pressure plate disposed on the winding shell, a mounting frame disposed on the winding shell, two slide rods disposed on the mounting frame, an upper pressure plate slidably sleeved on the two slide rods, and an abutment spring sleeved on the slide rods disposed between the upper pressure plate and the mounting frame.

[0010] Furthermore, several pointed conical strips are arranged in an array on the opposite sides of the upper and lower pressure plates.

[0011] Furthermore, the host is provided with a snap-fit ​​component for snapping and fixing the take-up shell.

[0012] Furthermore, the snap-fit ​​component includes an annular plate fixed to the winding shell, an outer cylinder fixed to the main unit, an inner rod that slides through the outer cylinder and engages with the annular plate, a limiting plate fixed to the inner rod, and a limiting spring sleeved on the inner rod between the limiting plate and the inner wall of the outer cylinder.

[0013] Furthermore, a limiting ring is fixed at one end of the wire near the electrode sheet, and a sponge ring is provided on one side of the limiting ring.

[0014] Furthermore, the host is connected to two soft straps, one of which has a buckle at one end, and the other has a Velcro sub-strip and a Velcro master-strip.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figures 1-9 As shown, one embodiment of this application discloses a portable intelligent electrotherapy device, including a main unit 1 with a USB interface 2 on one side. Preferably, the main unit 1 includes a casing with a display screen and buttons. The casing also houses an electrostimulation therapy module (main control chip STM32F103C8T6) and a power module (lithium battery for portability). The power module provides power, and the electrostimulation therapy module generates millivolt-level pulses. The buttons allow selection of different treatment modes and adjustment of the current frequency, intensity, and waveform. The display screen facilitates viewing treatment information. The casing 1 may also include a Bluetooth module for intelligent control via smartphones or other smart terminals. The device also includes:

[0028] A take-up shell 3 has a guide rod 4 that rotates through it. The guide rod 4 has a through groove 5, and the take-up shell 3 has a through groove 6. A USB connector 7, which mates with a USB interface 2, is located on one side of the take-up shell 3. A wire 8 is connected to the USB connector 7 via an electric slip ring. The free end of the wire 8 moves sequentially through the through groove 5 and the through groove 6 and is inserted into an electrode plate 10. Preferably, the electrode plate 10 has a socket, and the wire 8 has a plug that connects to the socket, making the electrode plate 10 and the wire 8 detachably connected. The wire 8 is divided into two sections; one section is connected to the USB connector 7, and the two sections are connected by an electric slip ring. Figure 9As shown, the longitudinal section of the through groove 5 is L-shaped, with one end of the groove at the shaft end of the guide rod 4 and the other end of the groove located on the surface of the guide rod 4. Another section of the wire 8 movably passes through the through groove 5 and connects to the electrode plate 10. The winding shell 3 is provided with an adjustment mechanism 9 for adjusting the rotation of the guide rod 4. During electrotherapy, the USB connector 7 is plugged into the USB interface 2, and the electrode plate 10 is placed against the skin. The host 1 generates millivolt-level pulse electricity, which is conducted to the limb through the wire 8 and the electrode plate 10, thereby performing electrotherapy. The wire 8 can be wound up reasonably according to the required length of the wire 8 for the treatment area. During winding, the adjustment mechanism 9 is used to adjust the wire 8. When the guide rod 4 rotates, the wire 8 moves through the through slot 5. Therefore, when the guide rod 4 rotates, the wire 8 can be wound around the guide rod 4 and stored in the winding shell 3. Since the wire 8 is connected to the USB connector 7 through an electric slip ring, it can ensure that the wire 8 conducts electricity normally (transmits pulse electricity). The wire 8 can be wound at one end (the end connected to the electrode plate 10). At the same time, the USB connector 7 will not interfere with the winding of the wire 8. When not performing treatment, the wire 8 can be wound in the winding shell 3 to avoid the wires 8 from tangling and knotting together, thereby improving practicality and making it easy to carry when doing outdoor sports.

[0029] In this solution, without affecting normal conductive transmission, one end of the wire 8 connected to the electrode plate 10 can be rolled up and the main unit 1 can be placed in a pocket. The exposed length of the wire 8 can be reasonably adjusted according to the length required by the treatment site, making it convenient to carry for outdoor treatment. At the same time, when not in use, the wire 8 can be stored in the retractable shell 3 to prevent the wires 8 from getting tangled and knotted, thereby improving practicality.

[0030] like Figure 7 and Figure 9 As shown, in some embodiments, the adjusting mechanism 9 includes baffles 901 fixed at both ends of the guide rod 4. Both ends of the guide rod 4 are connected to the inner wall of the winding shell 3 by a spiral spring 902. The winding shell 3 is provided with a fixing member 903 for fixing the wire 8. By connecting the spiral spring 902 between the guide rod 4 and the winding shell 3, the wire 8 can be automatically wound onto the guide rod 4 by utilizing the torque generated by the spiral spring 902. In use, the wire 8 is pulled out and then fixed by the fixing member 903. When it is necessary to rewind, the fixing member 903 can be released to automatically rewind the wire 8. The baffles 901 are used to limit the spiral spring 902 to ensure that it can generate torque normally. At the same time, it can also prevent the wound wire 8 from contacting the spiral spring 902, avoiding mutual interference between the two, thereby improving practicality.

[0031] like Figure 8As shown, in some embodiments, the fixing member 903 includes a lower pressure plate 9031 disposed on the winding shell 3, a mounting bracket 9032 disposed on the winding shell 3, two sliding rods 9033 disposed on the mounting bracket 9032, an upper pressure plate 9034 slidably sleeved on the two sliding rods 9033, and an abutment spring 9035 sleeved on the sliding rod 9033 installed between the upper pressure plate 9034 and the mounting bracket 9032. When the wire 8 is pulled to extend, the upper pressure plate 9034 slides upward first. The upper pressure plate 9034 slides along the slide rod 9033 and presses against the contact spring 9035. After the wire 8 is pulled out, the upper pressure plate 9034 is loosened. Under the elastic force of the contact spring 9035, the upper pressure plate 9034 and the lower pressure plate 9031 press against the wire 8, and the wire 8 is fixed by the frictional force. Preferably, the elastic force of the two contact springs 9035 is greater than the torque of the two coil springs 902 to ensure that the wire 8 can be fixed.

[0032] like Figure 8 As shown, in some embodiments, a plurality of pointed conical strips 11 are arranged in an array on the opposite sides of the upper pressure plate 9034 and the lower pressure plate 9031. By providing pointed conical strips 11 on the upper pressure plate 9034 and the lower pressure plate 9031, the frictional force of the two pressing against the wire 8 is increased, thereby further improving the fixing effect on the wire 8.

[0033] like Figure 7 As shown, in some embodiments, the host 1 is provided with a snap-fit ​​connector 12 for snapping and fixing the winding shell 3. Since the wire 8 is only wound up at one end, by providing the snap-fit ​​connector 12 on the host 1 for the winding shell 3, not only is the connection between the wire 8 and the host 1 further strengthened, but also, when not in use, there is no need to separate the USB interface 2 and the USB connector 7. The wire 8 can be directly wound up and the winding shell 3 fixed on the host 1, further improving the portability for outdoor use.

[0034] like Figure 7As shown, in some embodiments, the snap-fit ​​component 12 includes an annular plate 1201 fixed to the take-up shell 3, an outer cylinder 1202 fixed to the main unit 1, an inner rod 1203 that slides through the outer cylinder 1202 and engages with the annular plate 1201, a limiting plate 1204 fixed to the inner rod 1203, and a limiting spring 1205 sleeved on the inner rod 1203 installed between the limiting plate 1204 and the inner wall of the outer cylinder 1202. When snapping the main unit 1 to the take-up shell 3, first pull down... Move the inner rod 1203, causing the limiting plate 1204 to press the limiting spring 1205. Then, insert the USB interface 2 and the USB connector 7. At this time, the ring plate 1201 and the inner rod 1203 are aligned. Then, loosen the inner rod 1203. Under the elastic force of the limiting spring 1205, the inner rod 1203 moves through the ring plate 1201, thereby locking the winding shell 3 onto the main unit 1. Locking and unlocking can be done simply by pulling the inner rod 1203, making adjustment convenient.

[0035] like Figure 4 As shown, in some embodiments, a limiting ring 13 is fixed at one end of the wire 8 near the electrode plate 10, and a sponge ring 14 is provided on one side of the limiting ring 13. Since the wire 8 is wound up by the spiral spring 902, the winding speed is relatively fast. By setting the limiting ring 13 on the wire 8, the end of the wire 8 is prevented from being completely wound into the collecting shell 3. At the same time, the sponge ring 14 is provided on the limiting ring 13 to prevent the limiting ring 13 from having a hard impact with the winding shell 3 under the torque of the spiral spring 902, so as to play a protective role.

[0036] like Figure 1 and Figure 3 As shown, in some embodiments, the main unit 1 is connected to two soft straps 15. One soft strap 15 has a buckle at one end, and the other soft strap 15 is provided with a Velcro sub-strap and a Velcro main strap. When performing outdoor mobile treatment, if the clothing does not have pockets, the main unit 1 can be fitted to the arm or other parts, and the end of the other soft strap 15 can be moved through the buckle. Then, by using the Velcro sub-strap and the Velcro main strap, the main unit 1 can be fixed to the arm using the two soft straps 15. This not only makes it convenient to carry the treatment outdoors, but also makes it convenient to observe the treatment data displayed on the screen in real time, thereby improving its practicality.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
