In this way, the flexible water absorbent member will be in a wet state for a long time, which is easy to breed bacteria and thus easy to contaminate the shock wave therapy instrument. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a heat dissipation structure of a shock wave therapy instrument that facilitates the external drainage of the cooling water in the flexible water absorbent member.

[0006] To solve the above technical problems, the technical solution adopted by the present utility model is: to provide a heat dissipation structure for a shock wave therapeutic apparatus, including an outer cylinder, a fan, and an inner cylinder.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following is further detailed through specific embodiments:

[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, the present utility model provides a heat dissipation structure for a shock wave therapy instrument, including an outer cylinder 1, a fan 2 and an inner cylinder 3. The outer cylinder 1 is sleeved outside the inner cylinder 3. The outer cylinder 1 and the inner cylinder 3 are jointly fixedly connected with a lower baffle 4. The lower baffle 4 is provided with a through groove matching the inner cylinder 3. The fan 2 is assembled in the through groove. The side wall of the inner cylinder 3 has a number of air-permeable holes 31 that penetrate through the inside and outside. A flexible water-absorbing member 5 is assembled between the inner cylinder 3 and the outer cylinder 1. A pressing plate 6 for pressing the flexible water-absorbing member 5 is longitudinally slidably connected to the outside of the inner cylinder 3. The lower part of the side wall of the outer cylinder 1 has a water passing hole 11. When it is necessary to clean the cooling water in the flexible water-absorbing member after use, only need to push the pressing plate 6 down to the limit position, then it will press the flexible water-absorbing member 5, so as to achieve the auxiliary external discharge of the cooling water in the flexible water-absorbing member 5. After the heat dissipation of the shock wave therapy instrument is completed, the present utility model can discharge the residual cooling water in the flexible water-absorbing member 5, prevent the cooling water from breeding bacteria due to staying in the flexible water-absorbing member 5 for too long, and avoid polluting the handle of the shock wave therapy instrument.

[0024] In order to facilitate the installation of the outer cylinder 1, an installation plate 14 is further provided on the outer cylinder 1. A number of bolt holes 131 are provided on the installation plate 14. The outer cylinder 1 is fixed on the shock wave therapy instrument by bolts passing through the bolt holes 131. A top plate 15 is further provided on the top of the outer cylinder 1. A placement hole 151 for inserting the handle of the shock wave therapy instrument is provided on the top plate 15. After the use of the handle of the shock wave therapy instrument is completed, it is inserted into the placement hole 151 for heat dissipation. Before use, it is first necessary to add water to the flexible water-absorbing member 5. Specifically, an external water storage bottle 8 is provided at the bottom of the outer cylinder 1. The external water storage bottle 8 is rotatably connected to the water passing hole 11. A rotating member 111 is provided in the water passing hole 11. A connecting pipe 81 is provided at the bottom of the external water storage bottle 8. The connecting pipe 81 is fixedly connected to the rotating member 111. The top of the external water storage bottle 8 is threadedly connected with a bottle cap 9. When water needs to be added, first press the flexible water-absorbing member 5 through the pressing plate 6 to make it reach a contracted state. Then open the bottle cap 9 and rotate the external water storage bottle 8, and add the cooling water to be added into the external water storage bottle 8. The cooling water flows through the water passing hole 11 to the space between the outer cylinder 1 and the inner cylinder 3 to replenish the flexible water-absorbing member 5. In order to prevent too much cooling water from flowing out through the air-permeable holes 31 during the water-adding process, the distance between the lowermost air-permeable hole 31 and the lower baffle 4 is designed to be greater than the minimum compression height of the flexible water-absorbing member 5. Through this design, the added cooling water can completely immerse the flexible water-absorbing member 5 without flowing out through the air-permeable holes 31.

[0025] In order to facilitate the operator to control the extrusion plate 6, an operation handle 61 is fixedly connected to the front end of the extrusion plate 6, and the up and down movement of the extrusion plate 6 is realized by pushing the operation handle 61. Specifically, the operation handle 61 is in a "U" shape, and both ends of the operation handle 61 are fixedly connected to the extrusion plate 6. Two strip-shaped openings 12 are formed in one side of the outer cylinder 1 corresponding to the operation handle 61, and both ends of the operation handle 61 are respectively inserted into the two strip-shaped openings 12. During use, the operator only needs to pull the operation handle 61 to slide up and down. At this time, both ends of the operation handle 61 move up and down in the two strip-shaped openings 12 respectively. In order to enable the extrusion plate 6 to quickly reset after extrusion, a support plate 32 is provided at the top of any side surface of the inner shell ring 4. A spring 33 is fixedly connected to the bottom of the support plate 32, and the end of the spring 33 away from the support plate 32 is fixedly connected to the top of the extrusion plate 6. The support plate 32 and the spring 33 can provide a pulling force for the extrusion plate 6, and the flexible water-absorbing member 5 between the outer cylinder 1 and the inner shell ring 4 can provide a supporting force for the extrusion plate 6, which can make the extrusion plate 6 relatively stable. At the same time, the elastic contraction of the spring 33 can enable the extrusion plate 6 to quickly automatically reset after being pressed down.

[0026] In order to prevent the cooling water from flowing out of the two strip-shaped openings 12 during the water filling process, in this embodiment, two sealing strips 611 are fixedly connected to both ends of the operation handle 61. Both sealing strips 611 are slidably connected to the outer cylinder 1. The two sealing strips 611 are respectively matched with the two strip-shaped openings 12 so that the two sealing strips 611 close the two strip-shaped openings 12, avoiding the external leakage of the cooling water after it enters the outer cylinder 1. In order to limit the two sealing strips 611, a sliding track 13 adapted to the two sealing strips 611 is provided on one side of the outer cylinder 1 corresponding to the two sealing strips 611. The sliding track 13 can limit the two sealing strips 311 so that they can only slide within the sliding track 13. At the same time, it can also make the two sealing strips 611 better fit outside the two strip-shaped openings 12 without generating gaps.

[0027] After the water replenishment is completed and it is needed to be used, turn on the fan 2 to accelerate the air circulation to facilitate the heat dissipation of the shock wave handle. Since the top plate 15 shields the outer cylinder 1 and the inner cylinder 3, in order to achieve a better ventilation effect, a connecting block 7 is provided between the outer side of the top of the inner cylinder 3 and the inner side of the top of the outer cylinder 1, and a ventilation hole 71 that communicates the inside of the inner cylinder 3 with the outside of the outer cylinder 1 is provided in the connecting block 7. The outer cylinder 1 and the inner cylinder 3 can be connected and fixed through the connecting block 7. At the same time, through the ventilation hole 71, the air inside the inner cylinder 3 can circulate, accelerating the flow of water molecules, improving the cooling effect, and accelerating the heat dissipation speed. During the heat dissipation process, in order to prevent the water molecules of the cooling water from adhering to the inner wall of the inner cylinder 3 and flowing down to the bottom of the inner cylinder 3 to remain, in this embodiment, there is a water passing gap between the outer side of the fan 2 and the inner wall of the through groove, and the outer side of the fan 2 and the inner wall of the through groove are connected by a plurality of connecting rods 21. Since the fan 2 is connected by the connecting rods 21, a gap will be formed with the through groove. Through this design, the water molecules adhering to the inner wall of the inner cylinder 3 can flow out of the inner cylinder 3 through the gap between the fan 2 and the through groove, preventing water residues and generating dirt.

[0028] After use, when it is necessary to clean the unevaporated cooling water in the flexible water absorbent member 5, close the external water storage bottle 8 with the bottle cap 9, and then push the extrusion plate 6 down to the limit position to completely squeeze the flexible water absorbent member 5. After the cooling water in the flexible water absorbent member 5 is discharged, it flows into the external water storage bottle 8 through the water passing hole 11. Finally, open the bottle cap 9 to discharge the cooling water in the external water storage bottle 8. In this way, the remaining cooling water in the flexible water absorbent member 5 can be discharged externally, preventing the cooling water from staying in the flexible water absorbent member 5 for too long and breeding bacteria, and avoiding contamination of the shock wave treatment instrument handle.

All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
