Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation instruments, in particular to a heat dissipation and dustproof mechanism and a handheld ultrasonic rehabilitation instrument. Background Art

[0002] A handheld ultrasound rehabilitation device is a portable physical therapy device commonly used in the field of rehabilitation medicine. It integrates key components such as an ultrasound generator and a treatment head into a device that is easy to hold and operate. By utilizing the mechanical vibration and thermal effects of ultrasound, it directly acts on human tissue, thereby achieving therapeutic purposes such as promoting blood circulation, relieving pain, eliminating inflammation, and promoting tissue repair. It is non-invasive, easy to operate, safe and reliable.

[0003] In the prior art, during the use of a handheld ultrasonic rehabilitation device, since the entire device is controlled by a main control board, various electronic components on the circuit board will generate heat when working. When current passes through these components, due to the presence of resistance, electrical energy will be consumed and converted into heat energy. In order to dissipate heat from the main control board, a heat dissipation slot is often opened in the casing of the handheld ultrasonic rehabilitation device.

[0004] However, by opening a heat dissipation slot, the heat dissipation efficiency is low due to the small heat dissipation slot. At the same time, during long-term use, the heat dissipation slot will be blocked due to the accumulation of dust, and some dust and other impurities will also adhere to the main control board, affecting the service life of the electronic components thereon, thereby reducing the heat dissipation effect and easily causing the main control board to overheat and be damaged, thereby reducing the service life of the main control board and also reducing the service life of the entire rehabilitation device. Utility Model Content

[0005] The purpose of the present utility model is to provide a heat dissipation and dustproof mechanism and a handheld ultrasonic rehabilitation device to solve the problems raised in the above background technology.

[0012] Preferably, a cooling fan is provided on one side of the bottom of the rod, and the cooling fan is fixedly mounted on the bottom end of the handheld part of the rehabilitation instrument. The main control board is fixedly mounted in the handheld part of the rehabilitation instrument by screws, and a silicone grease layer is coated between one side of the main control board and the cooling plate.

When the rehabilitation instrument is in use, the heat generated by the main control board 6 is absorbed by the heat dissipation plate 7, and the heat of the heat dissipation plate 7 is conducted to the heat-conducting copper tube 8. After the aluminum heat sink 9 absorbs the heat, the heat is discharged through the heat dissipation fan 10, thereby improving the heat dissipation effect and heat dissipation efficiency, and extending the service life of the main control board 6 and the entire rehabilitation instrument.

[0028] The bottom of the mounting sleeve 1 is in contact with the lower sealing ring 12, and the upper surface of the lower sealing ring 12 is fixedly connected to the lower surface of the dust cover 5. The upper and lower sealing rings 11 and 12 are arranged symmetrically about the mounting sleeve 1. The upper side of the mounting sleeve 1 is fixedly connected to the upper sealing ring 11, and the bottom of the mounting sleeve 1 is in contact with the lower sealing ring 12. The upper surface of the lower sealing ring 12 is fixedly connected to the lower surface of the dust cover 5. The upper and lower sealing rings 11 and 12 are arranged so as to improve the sealing between the mounting sleeve 1 and the dust cover 5. The lower sealing ring 12 and the dust cover 5 are fixedly connected to one side of the fixing block 4 through the L-shaped plate 13. The lower surface of the mounting sleeve 1 is provided with a mounting groove 14, and the lower surface of the connecting block 3 is provided with a slide groove 15. The top of the slide groove 15 is provided with a groove 16. The L-shaped plate 13 fixes the lower sealing ring 12 and the dust cover 5. The mounting groove 14 on the lower side of the mounting sleeve 1 is convenient for the installation of the dust cover 5. The slide 15 provided is convenient for the sliding insertion of the fixed block 4, the groove 16 provided in the slide 15 is convenient for the clamping of the connecting block 3, the mounting groove 14 is slidingly connected to the dust cover 5, the fixed block 4 is slidingly connected to the slide 15, one end of the fixed block 4 is fixed with a limit block 17, one side of the limit block 17 is fixedly connected to the clamping block 19 through an inner spring 18, the limit block 17 is fixedly installed at one end of the fixed block 4, the inner spring 18 is fixed by the limit block 17, and the inner spring 18 is fixed. It is connected between the limit block 17 and the card block 19, and the card block 19 is slidably connected to the groove 16. A plug rod 20 is installed on one side of the card block 19, and the plug rod 20 is slidably sleeved in the connecting block 3. One end of the plug rod 20 is fixedly connected to the connecting block 3 through an external spring 21. The card block 19 is slidably clamped in the groove 16, thereby clamping the fixed block 4 and the connecting block 3. The plug rod 20 is slidably sleeved on the side wall of the connecting block 3, and the plug rod 20 is fixedly connected to one end of the plug rod 20 through an external spring 21.

[0029] The handheld part 2 of the rehabilitation instrument is fixed in the mounting sleeve 1, and the dust cover 5 is slidably inserted into the mounting groove 14 opened at the bottom of the mounting sleeve 1. At the same time, the fixing block 4 is also slidably inserted into the slide groove 15 opened in the connecting block 3 through the connection of the L-shaped plate 13, so that the lower sealing ring 12 abuts against the bottom of the mounting sleeve 1. The upper sealing ring 11 and the lower sealing ring 12 are arranged to improve the sealing between the mounting sleeve 1 and the dust cover 5. When the fixing block 4 is inserted into the slide groove 15, the block 19 compresses the inner spring 18 under the constraint of the slide groove 15. As the fixing block 4 is pushed in, when the block 19 moves to the groove 16, the block 19 is compressed under the elastic force of the inner spring 18. One end is inserted into the groove 16, thereby fixing the fixing block 4 and the connecting block 3, and then the dust cover 5 is placed on the outside of the heat dissipation groove opened at the bottom of the handheld part 2 of the rehabilitation instrument, so as to prevent the heat dissipation groove from being blocked by dust and other impurities. At the same time, it also prevents dust and other impurities from adhering to the main control board 6 and reducing the service life of the main control board 6. In addition, after the dust cover 5 has been used for a period of time, by pressing the insertion rod 20 toward the inside of the connecting block 3, the insertion rod 20 compresses the outer spring 21 and pushes the card block 19 out of the groove 16, and at the same time pulls the fixing block 4 outward, so that the dust cover 5 can be removed and cleaned, avoiding clogging of the dust cover 5 and subsequent continued use.

[0030] Example 3: Based on Example 2, a cooling fan 10 is provided on one side of the bottom of the insertion rod 20, and the cooling fan 10 is fixedly installed at the bottom end of the rehabilitation instrument handheld part 2.

[0031] The main control board 6 is electrically connected to the heat dissipation fan 10. A silicone grease layer 22 is applied between the main control board 6 and the heat dissipation plate 7 to increase the heat absorption area and better conduct heat. When the main control board 6 generates heat, the heat is conducted to the heat dissipation plate 7 through the silicone grease layer 22. The heat dissipation plate 7 absorbs the heat and then transfers it to the heat-conducting copper tube 8. After the aluminum heat sink 9 absorbs the heat of the heat-conducting copper tube 8, the heat is discharged by starting the heat dissipation fan 10. The aluminum heat sink 9 increases the contact area with the air by multi-layer stacking to improve the heat dissipation efficiency, thereby avoiding overheating and damage to the main control board 6, reducing the service life of the main control board 6 and also reducing the service life of the entire rehabilitation device.
