Description

Technical Field

[0001] The present invention belongs to the field of physiotherapy instruments, and particularly relates to a portable multi-functional medium-frequency physiotherapy instrument. Background Art

[0002] The medium-frequency physiotherapy instrument is a new type of physiotherapy instrument that combines Western modern electronics, magnetotherapy, and traditional Chinese medicine viscera theory and meridian theory. It stimulates human acupoints by conducting special-frequency current through a thermal electromagnetic contact head, thereby producing the therapeutic effects of acupuncture, heat therapy, electrotherapy, and magnetotherapy. It has the effects of dredging meridians and collaterals, regulating qi and blood, removing stasis and relieving pain, stimulating nerve and muscle tissues, promoting blood circulation, and exercising skeletal muscles.

[0003] For existing medium-frequency physiotherapy instruments, the main unit and the electrode wire are generally detachably arranged. When in use, the plug of the electrode wire needs to be inserted into the output interface on the main unit, and then the electrode patch is inserted into the other end of the electrode wire before it can be used. After use, the electrode wire usually needs to be folded and stored, which is very troublesome. Since most current medium-frequency physiotherapy instruments are for home use, this problem is not so serious. However, when the medium-frequency physiotherapy instrument is used commercially, especially when users need to scan a code for self-service use, such as in a health house, if users are still required to store the electrode wire by themselves, it will seriously consume the patience of users. After using the product, users may not take the initiative to store it, resulting in serious damage to the electrode wire.

[0004] In addition, after long-term use, a large amount of human grease and stains will adhere to the electrode wire. If it is for personal use by a user, they may not care. However, when used by multiple different users, users may dislike the electrode wire and stop using the medium-frequency physiotherapy instrument, which will reduce the income of the merchant.

[0038] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0040] As Figures 1 - 10As shown in the figure, a portable multi-functional intermediate frequency physiotherapy instrument provided by the present invention includes a box body 1 and a box cover 2. The box cover 2 is hinged to the top of the box body 1. A lock is provided between the box body 1 and the box cover 2. A handle is provided on the side of the box body 1. The box body 1 and the box cover 2 are fixed by the lock, and then the physiotherapy instrument can be carried away by holding the handle, making the physiotherapy instrument easy to carry. A circuit board and a control panel 5 are provided inside the box body 1. A display screen 4 and a speaker 3 are provided inside the box cover 2. The display screen 4 and the speaker 3 are electrically connected to the circuit board through wires. The control panel 5 includes a plurality of function buttons, function knobs and a plurality of output sockets, so as to facilitate the user to adjust the output intensity according to different prescriptions. A material handling line 6 is electrically connected to the circuit board, and one end of the material handling line 6 is connected with a detachable electrode patch;

[0041] A wire winding mechanism 7 is installed inside the box body 1, and the wire winding mechanism 7 is used for winding the material handling line 6;

[0042] A dissolving mechanism 9 and a wiping mechanism 8 are also installed inside the box body 1. The middle part of the material handling line 6 passes through the output ends of the dissolving mechanism 9 and the wiping mechanism 8. The dissolving mechanism 9 is used for dissolving the grease stained on the material handling line 6, and the wiping mechanism 8 is used for wiping off the dissolved grease, so that the material handling line 6 remains as clean as new, avoiding affecting the user experience.

[0043] When the device is in use, the wire winding mechanism 7 releases and winds the material handling line 6, without the need for the user to manually wind it. After use, the user can cooperate to wind the material handling line 6, avoiding serious loss of the material handling line 6 due to long-term exposure to the outside. And each time the material handling line 6 is wound, the dissolving mechanism 9 and the wiping mechanism 8 will clean the material handling line 6, making the material handling line 6 as new, not affecting the user experience, and avoiding the reduction of the merchant's income.

[0044] In order to facilitate the device to be carried out or used by different users, a first storage slot 10 and a second storage slot 11 are also provided inside the box body 1. The first storage slot 10 is used to place unopened electrode patches, heat therapy straps, massage slippers, etc. The second storage slot 11 is used to place additional material handling lines 6 for multiple people to use.

[0045] A portable multifunctional intermediate frequency physiotherapy instrument provided by the present invention. In this embodiment, the wire winding mechanism 7 includes a wire winding disc 71 rotatably installed inside the box body 1. One end of the material guiding wire 6 is wound around the wire winding disc 71. A first motor 73 is fixedly installed inside the box body 1. One end of the first motor 73 is fixedly connected to the wire winding disc 71. A first electromagnetic clutch 72 is also provided between the first motor 73 and the wire winding disc 71. A first pulley group 74 is fixedly installed inside the box body 1. One end of the material guiding wire 6 bypasses the first pulley group 74 and passes out from the top of the control panel 5.

[0046] Specifically, the wire winding mechanism 7 further includes two second pulley groups 75. One end of the material guiding wire 6 passes through the two second pulley groups 75 and the first pulley group 74 in sequence, thus forming a "U" - shaped loop. The dissolving mechanism 9 and the wiping mechanism 8 are respectively arranged on the two longer line segments of the "U" - shaped loop, and the dissolving mechanism 9 is closer to the end of the material guiding wire 6. When the wire winding mechanism 7 winds up the material guiding wire 6, the dissolving mechanism 9 first dissolves the grease on the material guiding wire 6, and then the wiping mechanism 8 wipes off the dissolved grease on the material guiding wire 6.

[0047] In addition, "rewinding" and "unwinding" function buttons can be set on the control panel 5. When the "unwinding" button is pressed, the first electromagnetic clutch 72 disconnects the power supply, enabling the user to pull out one end of the material guiding wire 6. When the "rewinding" button is pressed, the first electromagnetic clutch 72 and the first motor 73 are powered on. The first motor 73 drives the wire winding disc 71 to rotate through the first electromagnetic clutch 72, and the wire winding disc 71 winds up the material guiding wire 6.

[0048] A portable multifunctional intermediate frequency physiotherapy instrument provided by the present invention. In this embodiment, the dissolving mechanism 9 includes a dissolving cylinder 95 and a piston cylinder 93. The dissolving cylinder 95 and the piston cylinder 93 are both fixedly installed inside the box body 1. A dissolving sponge 910 is arranged inside the dissolving cylinder 95. The material guiding wire 6 passes through the middle of the dissolving sponge 910. The top of the dissolving cylinder 95 is fixedly connected to a feeding cylinder 94. A plurality of feeding holes 99 communicating with the inside of the feeding cylinder 94 are opened at the top of the dissolving cylinder 95;

[0049] One end of the piston cylinder 93 is communicated with a feeding pipe 92. One end of the feeding pipe 92 is communicated with the inside of the feeding cylinder 94. A piston block is slidably installed inside the piston cylinder 93. The side of the piston block facing away from the feeding pipe 92 is fixedly connected to a piston rod 96. Alcohol is arranged inside the piston cylinder 93. A feeding pipe 91 for adding alcohol is communicated with the side of the piston cylinder 93. One end of the feeding pipe 91 passes out from the top of the control panel 5;

[0050] Inside the box body 1, a stepping motor 98 is also installed. The output shaft of the stepping motor 98 is fixedly connected to a screw rod 97, and the screw rod 97 is threadedly connected to the piston rod 96.

[0051] During use, start the stepping motor 98. The stepping motor 98 drives the screw rod 97 to rotate. The screw rod 97 drives the piston rod 96 to move a certain distance. The piston rod 96 drives the piston block to move. The piston block squeezes the alcohol in the piston barrel 93, and squeezes the alcohol into the feeding barrel 94 through the feeding pipe 92. Then the alcohol penetrates into the dissolving sponge 910 from the feeding hole 99. When the material handling line 6 moves through the middle of the dissolving sponge 910, the alcohol in the dissolving sponge 910 will dissolve the grease on the material handling line 6.

[0052] Specifically, when starting the first motor 73, the stepping motor 98 can be started synchronously. After the piston block squeezes the alcohol into the dissolving sponge 910, the power supply of the stepping motor 98 is cut off to avoid excessive extrusion of alcohol and waste. After the alcohol in the piston barrel 93 is used up (a distance sensor can be set in the piston barrel 93. The distance sensor is used to detect the distance between the piston block and the end of the piston barrel 93 where the feeding pipe 92 is installed. The closer the piston block is to the end of the piston barrel 93, the less alcohol is in the piston barrel 93), the stepping motor 98 can be started in reverse to drive the piston block away from the feeding pipe 92 (a "refilling" function button can be set on the control panel 5), and then alcohol can be added to the piston barrel 93 through the refilling pipe 91.

[0053] A portable multifunctional intermediate frequency physiotherapy apparatus provided by the present invention. In this embodiment, the wiping mechanism 8 includes a first cloth reel 83, a second cloth reel 86 and a wiping cylinder 85. The first cloth reel 83, the second cloth reel 86 and the wiping cylinder 85 are all installed inside the box body 1. A double-layer cloth 84 is wound on the first cloth reel 83. One end of the double-layer cloth 84 passes through the wiping cylinder 85 and is wound on the second cloth reel 86. The material handling line 6 passes through the middle of the double-layer cloth 84 inside the wiping cylinder 85.

[0054] When the material handling line 6 moves inside the double-layer cloth 84, the upper layer cloth and the lower layer cloth of the double-layer cloth 84 can wipe the entire circumferential side of the material handling line 6.

[0055] A portable multifunctional medium-frequency physiotherapy apparatus provided by the present invention. When the same part of the double-layer cloth 84 wipes the grease on the material handling line 6 for a long time, the grease will gradually accumulate on the double-layer cloth 84, resulting in a gradual reduction in the cleaning effect of the double-layer cloth 84. In this embodiment, the wiping mechanism 8 further includes an intermittent cloth winding mechanism 87. The intermittent cloth winding mechanism 87 includes a slide rail 878 fixedly installed inside the box body 1. A rack 876 is slidably installed on the slide rail 878. A second tension spring 875 is connected between the rack 876 and the slide rail 878. A first one-way gear 873 is installed on the output shaft of the first motor 73. The first one-way gear 873 is meshed with the rack 876. A first stop block 877 for blocking the rack 876 is fixedly connected to the end of the slide rail 878 close to the first motor 73;

[0056] A transmission rod 872 is also rotatably installed inside the box body 1. A second one-way gear 874 is installed on the transmission rod 872. The second one-way gear 874 is meshed with the rack 876. A transmission pair 871 is connected between one end of the transmission rod 872 and the second cloth winding disc 86. Both the first cloth winding disc 83 and the second cloth winding disc 86 are rotatably installed. The transmission pair 871 is a bevel gear pair.

[0057] Specifically, when the first motor 73 drives the wire winding disc 71 to rotate and wind up the material handling line 6, the first motor 73 will also rotate through the first one-way gear 873. The first one-way gear 873 drives the rack 876 to move. The rack 876 drives the second one-way gear 874 and the transmission rod 872 to rotate. The transmission rod 872 drives the second cloth winding disc 86 to rotate through the transmission pair 871. When the rack 876 is blocked by the first stop block 877, the rack 876 stops moving, the first one-way gear 873 no longer rotates, and at the same time, the second cloth winding disc 86 also no longer rotates, so that the second cloth winding disc 86 can wind up a small section of the double-layer cloth 84, making different parts of the double-layer cloth 84 contact the material handling line 6 in the wiping cylinder 85, and avoiding the gradual accumulation of grease.

[0058] A portable multifunctional medium-frequency physiotherapy apparatus provided by the present invention. In this embodiment, the first one-way gear 873 includes a first outer gear 8731 rotatably installed on the output shaft of the first motor 73 and a first inner wheel 8732 fixedly installed on the output shaft of the first motor 73. The first inner wheel 8732 is located inside the first outer gear 8731. A first installation groove is formed on the circumferential side surface of the first inner wheel 8732. A centrifugal driving block 8735 is slidably installed inside the first installation groove. A first tension spring 8734 is connected between the centrifugal driving block 8735 and the first inner wheel 8732. A plurality of first inner teeth 8733 adapted to the centrifugal driving block 8735 are fixedly connected to the inner side wall of the first outer gear 8731.

[0059] Specifically, when the first motor 73 drives the take-up reel 71 to wind up the material feeding line 6, the first motor 73 drives the first inner wheel 8732 to rotate. Under the action of centrifugal force (making the elasticity of the first tension spring 8734 less than the centrifugal force of the centrifugal drive block 8735), the centrifugal drive block 8735 is thrown out of the first installation groove. Then, the centrifugal drive block 8735 drives the first outer gear 8731 to rotate through the first internal teeth 8733, so that the first outer gear 8731 can drive the rack 876 to move;

[0060] When the rack 876 is blocked by the first stopper 877, the first outer gear 8731 is also blocked. When the centrifugal drive block 8735 encounters the first internal teeth 8733 again, under the extrusion force of the inclined surface of the first internal teeth 8733, the centrifugal drive block 8735 is extruded into the first installation groove, thus preventing the movement of the first motor 73 from being affected;

[0061] And because the first motor 73 rotates relatively fast, the first one-way gear 873 can always squeeze the rack 876 against the first stopper 877, preventing the second tension spring 875 from pulling the rack 876 back;

[0062] After the material feeding line 6 is wound up, the first motor 73 stops moving. Then, the first tension spring 8734 pulls the centrifugal drive block 8735 back into the first installation groove. The centrifugal drive block 8735 no longer blocks the first internal teeth 8733. The second tension spring 875 pulls the rack 876 back to its original position, and under the action of the second one-way gear 874, the second cloth winding disc 86 will not reverse again.

[0063] In a portable multi-functional intermediate frequency physiotherapy apparatus provided by the present invention, in this embodiment, the second one-way gear 874 includes a second outer gear 8741 rotatably installed on the transmission rod 872 and a second inner wheel 8743 fixedly installed on the transmission rod 872. The second inner wheel 8743 is located inside the second outer gear 8741. A plurality of second installation grooves are formed on the circumferential side surface of the second inner wheel 8743. A plurality of toggle blocks 8744 are slidably installed inside the plurality of second installation grooves. A compression spring 8745 is connected between the toggle block 8744 and the second installation groove. A plurality of second internal teeth 8742 adapted to the toggle block 8744 are fixedly connected to the inner side wall of the second outer gear 8741. Short inclined surfaces and long inclined surfaces with converging tops are respectively formed on both side surfaces of the toggle block 8744 along its rotation direction. When the rack 876 moves towards the first stopper 877, the second outer gear 8741 drives the second internal teeth 8742 to contact the short inclined surface.

[0064] Specifically, when the material handling line 6 is wound, the first motor 73 drives the rack 876 to move toward the first stopper 877 through the first one-way gear 873 (in this embodiment, as shown in FIG. Figure 9 As shown, the rack 876 moves to the left), the rack 876 drives the second outer gear 8741 to move clockwise, the second outer gear 8741 drives the shifting block 8744 and the second inner wheel 8743 to rotate through the second inner tooth 8742, the second inner wheel 8743 drives the transmission rod 872 to rotate, and the transmission rod 872 drives the second cloth winding plate 86 to rotate through the transmission pair 871;

[0065] When the rack 876 returns (the rack 876 moves to the right), the rack 876 drives the second outer gear 8741 to rotate counterclockwise, and the second outer gear 8741 drives the second inner gear 8742 to squeeze the long inclined surface of the toggle block 8744, and squeeze the toggle block 8744 into the second installation groove, and the second inner gear 8742 passes over the toggle block 8744 and continues to move until the rack 876 returns to its original position;

[0066] It is worth noting that, since the angle between the short inclined plane and the horizontal plane is greater than the angle between the long inclined plane and the horizontal plane, when the second inner tooth 8742 contacts the short inclined plane, the tangential force of the second inner tooth 8742 on the toggle block 8744 along the second inner wheel 8743 is greater than the radial force on the toggle block 8744. Therefore, when the resistance on the second inner wheel 8743 is small, the second inner tooth 8742 can push the second inner wheel 8743 to rotate clockwise through the toggle block 8744.

[0067] When the No. 2 inner tooth 8742 contacts the long inclined surface, the tangential force of the No. 2 inner tooth 8742 on the toggle block 8744 along the No. 2 inner wheel 8743 is smaller than the radial force exerted on the toggle block 8744. Therefore, the toggle block 8744 is easily squeezed into the second mounting groove by the No. 2 inner tooth 8742 instead of driving the toggle block 8744 and the No. 2 inner wheel 8743 to rotate counterclockwise.

[0068] The portable multifunctional medium frequency physiotherapy instrument provided by the present invention has a double-layer cloth 84 on the first cloth reel 83 that will be completely wound on the second cloth reel 86 after long-term use. At this time, the double-layer cloth 84 needs to be replaced. However, when the double-layer cloth 84 cleans the material processing line 6, different users use the material processing line 6 in different ways, resulting in different locations and amounts of grease on the material processing line 6, which will lead to different accumulations of stains on the double-layer cloth 84. If the double-layer cloth 84 is completely discarded, it will cause the double-layer cloth 84 to be damaged. Waste and frequent replacement of double-layer cloth 84 will be caused, which is inconvenient to use. In the present embodiment, the wiping mechanism 8 also includes a rewinding mechanism, which includes a No. 2 motor 81, and the No. 2 motor 81 is fixedly installed inside the box body 1. The output shaft of the No. 2 motor 81 is connected to one end of the No. 1 cloth winding disk 83, and a No. 2 electromagnetic clutch 82 is arranged between the No. 1 cloth winding disk 83 and the No. 2 motor 81. A No. 2 stopper 879 for preventing excessive movement of the rack 876 is fixedly connected to the slide rail 878.

[0069] Specifically, after the double-layer cloth 84 on the first cloth-winding disc 83 is released (a sensor may be provided to detect the thickness of the double-layer cloth 84 on the first cloth-winding disc 83), the power supply of the second motor 81 and the second electromagnetic clutch 82 is turned on (in normal use, the second electromagnetic clutch 82 is kept in a power-off state), the second motor 81 drives the first cloth-winding disc 83 to rotate, and the first cloth-winding disc 83 drives the second cloth-winding disc 86 to rotate through the double-layer cloth 84. Therefore, the double-layer cloth 84 on the second cloth-winding disc 86 can be taken back and reused. After repeated use, the double-layer cloth 84 can be replaced, which greatly extends the service life of the double-layer cloth 84.

[0070] When the second cloth winding disc 86 is reversed, the second cloth winding disc 86 will drive the transmission rod 872 to reverse through the transmission pair 871, and the transmission rod 872 will drive the second inner wheel 8743 to reverse (such as Figure 9 As shown in the figure, the No. 2 inner wheel 8743 rotates counterclockwise), the No. 2 inner wheel 8743 drives the No. 2 outer gear 8741 to rotate counterclockwise through the toggle block 8744, and the No. 2 outer gear 8741 drives the rack 876 to move rightward. Since the rack 876 is blocked by the No. 2 stopper 879, the No. 2 inner wheel 8743 is subjected to greater resistance. When the short inclined surface of the toggle block 8744 contacts the No. 2 inner tooth 8742, the toggle block 8744 is squeezed into the second mounting groove by the No. 2 inner tooth 8742, so that the toggle block 8744 continues to move over the No. 2 inner tooth 8742, thereby preventing the movement of the No. 2 inner wheel 8743, the transmission rod 872 and the No. 2 cloth winding disc 86 from being affected.

[0071] In addition, a "rewind" function button can be set on the control panel 5. After the double-layer cloth 84 on the first cloth winding disc 83 is completely released, pressing the "rewind" button can automatically implement the above steps.

[0072] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

[0073] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
