An electrosurgical equipment usually includes a high-frequency generator. A voltage-controlled constant-current pulse power supply device can be effectively applied to the high-frequency generator. The high-frequency generator requires a stable power supply to ensure the quality of the output signal. The voltage-controlled constant-current pulse power supply device can provide the required current to drive various high-frequency devices, such as amplifiers and oscillators. The key features of the voltage-controlled constant-current pulse power supply device are: voltage-controlled output: by adjusting the input voltage, the output current can be accurately controlled to adapt to different load requirements. Pulse modulation: it can output pulses with specific frequencies and widths, suitable for applications with requirements for time characteristics. Constant-current characteristic: maintain a constant output current within a certain range, and ensure the current stability even when the load changes, etc.

[0003] In the prior art, most traditional voltage-controlled constant-current pulse power supply devices are usually provided with heat dissipation holes on the device shell to dissipate heat from the electronic components inside the device and prevent damage to the electronic components caused by excessive temperature. However, when the device is used up, if the placement environment is too humid, the external moisture may enter the device through the heat dissipation holes, which may then cause damage to the electronic components. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem in the prior art that when the device is used up, if the placement environment is too humid, the external moisture may enter the device through the heat dissipation holes, which may then cause damage to the electronic components, and to propose a voltage-controlled constant-current pulse power supply device.

[0005] To achieve the above object, the utility model adopts the following technical solution: A voltage-controlled constant-current pulse power supply device, including a housing, wherein a plurality of uniformly distributed heat dissipation holes are penetrated through the inner wall of the housing, a T-shaped groove is opened on the inner wall of the housing, a T-shaped block is slidably installed inside the T-shaped groove, a rack is fixedly installed on the outer wall of the T-shaped block, a baffle is fixedly installed at one end of the rack, a turntable is rotatably installed on the outer wall of the housing, a connecting rod is fixedly installed on the side of the turntable close to the housing, one end of the connecting rod away from the turntable penetrates through the housing and a gear is fixedly installed, the gear is meshed with the rack, a fixing groove is opened at the end of the turntable close to the housing, a threaded hole is penetrated through the inner wall of the fixing groove, a threaded rod is threadedly connected inside the threaded hole, a pressing block is fixedly installed at the end of the threaded rod close to the housing, a rotating plate is fixedly installed at the end of the threaded rod away from the pressing block, and a holding rod is fixedly installed at the end of the turntable away from the connecting rod.

[0006] Preferably, a plurality of uniformly distributed limiting grooves are opened at the end of the baffle close to the heat dissipation holes, springs are fixedly installed on the inner walls of the plurality of limiting grooves, and a top block is fixedly installed at the end of each of the plurality of springs close to the heat dissipation holes.

[0007] Preferably, a plurality of uniformly distributed anti-slip strips are fixedly installed on the outer wall of the rotating plate.

[0008] Preferably, components are arranged on the inner wall of the housing.

[0009] Preferably, a switch is arranged on the outer wall of the housing, and two handles are fixedly installed at one end of the housing.

[0010] Preferably, the outer wall of the T-shaped block fits with the inner wall of the T-shaped groove.

[0011] Preferably, the outer walls of the plurality of top blocks respectively fit with the inner walls of the plurality of limiting grooves and the plurality of heat dissipation holes.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are as follows.

[0013] 1. In the utility model, when the device is used up, the staff holds the holding rod and then rotates the turntable. The turntable drives the gear to rotate through the connecting rod, and then drives the rack to move. At this time, the T-shaped block moves along the T-shaped groove. When the T-shaped block moves from one end of the T-shaped groove to the other end of the T-shaped groove, the baffle blocks the heat dissipation holes at this time, and it is very difficult for external moisture to enter the interior of the housing. Finally, the staff rotates the rotating plate, and the rotating plate drives the threaded rod to rotate, so that the threaded rod moves along the threaded hole, thereby driving the pressing block to move towards the housing until the pressing block contacts the housing. At this time, the pressure exerted by the pressing block on the housing increases the friction between the two, so that the turntable is fixed and prevents the turntable from rotating.

[0014] 2. In the present utility model, when the baffle moves, when the top block moves beside the heat dissipation hole, the elastic force of the spring pushes the top block into the heat dissipation hole, pushing out the dust that blocks the heat dissipation hole. When the inclined surface of the top block contacts the inner wall of the heat dissipation hole, the inner wall of the heat dissipation hole squeezes the top block, causing it to enter the limit groove, compressing the spring, and reciprocating back and forth. In this way, the dust in the heat dissipation hole can be cleaned up, enhancing the heat dissipation efficiency. Description of the Drawings

[0021] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1 - 5As shown in the figure, the utility model provides a voltage-controlled constant-current pulse power supply device, which includes a housing 1. A plurality of uniformly distributed heat dissipation holes 4 are penetrated through the inner wall of the housing 1. A T-shaped groove 12 is opened on the inner wall of the housing 1. A T-shaped block 13 is slidably installed inside the T-shaped groove 12. A rack 8 is fixedly installed on the outer wall of the T-shaped block 13. One end of the rack 8 is fixedly installed with a baffle 10. A turntable 5 is rotatably installed on the outer wall of the housing 1. A connecting rod 14 is fixedly installed on the side of the turntable 5 close to the housing 1. The end of the connecting rod 14 away from the turntable 5 penetrates through the housing 1 and is fixedly installed with a gear 9. The gear 9 is meshed with the rack 8. A fixing groove 15 is opened at the end of the turntable 5 close to the housing 1. A threaded hole 16 is penetrated through the inner wall of the fixing groove 15. A threaded rod 17 is threadedly connected to the inner wall of the threaded hole 16. One end of the threaded rod 17 close to the housing 1 is fixedly installed with a pressing block 18. One end of the threaded rod 17 away from the pressing block 18 is fixedly installed with a rotating plate 7. A grip rod 6 is fixedly installed at the end of the turntable 5 away from the connecting rod 14.

[0024] The effect achieved by the entire Embodiment 1 is that when the device is used up, the staff holds the grip rod 6 and then rotates the turntable 5. The turntable 5 drives the gear 9 to rotate through the connecting rod 14, and then drives the rack 8 to move. At this time, the T-shaped block 13 moves along the T-shaped groove 12. When the T-shaped block 13 moves from one end of the T-shaped groove 12 to the other end of the T-shaped groove 12, at this time, the baffle 10 blocks the heat dissipation holes 4, and it is very difficult for external moisture to enter the inside of the housing 1. Finally, the staff rotates the rotating plate 7, and the rotating plate 7 drives the threaded rod 17 to rotate, so that the threaded rod 17 moves along the threaded hole 16, thereby driving the pressing block 18 to move towards the housing 1 until the pressing block 18 contacts the housing 1. At this time, the pressure exerted by the pressing block 18 on the housing 1 increases the friction between the two, so that the turntable 5 is fixed and the turntable 5 is prevented from rotating.

[0025] Embodiment 2, as Figures 1 - 5 shown, further, a plurality of uniformly distributed limiting grooves 20 are opened at one end of the baffle 10 close to the heat dissipation holes 4. Springs 21 are fixedly installed on the inner walls of the plurality of limiting grooves 20. Top blocks 22 are fixedly installed at the ends of the plurality of springs 21 close to the heat dissipation holes 4.

[0026] Further, a plurality of uniformly distributed anti-slip strips 19 are fixedly installed on the outer wall of the rotating plate 7, which increases the friction on the outer wall of the rotating plate 7 and facilitates the staff to rotate the rotating plate 7.

[0027] Further, components 11 are arranged on the inner wall of the housing 1.

[0028] Further, a switch 3 is arranged on the outer wall of the housing 1 for starting and stopping the device. Two handles 2 are fixedly installed at one end of the housing 1.

[0029] Further, the outer wall of the T-shaped block 13 is fitted with the inner wall of the T-shaped groove 12 to prevent the rack 8 from tilting.

[0030] Furthermore, the outer walls of the multiple top blocks 22 are respectively in contact with the inner walls of the multiple limiting grooves 20 and the multiple heat dissipation holes 4, preventing the top blocks 22 from tilting.

[0031] The effect achieved by the entire Embodiment 2 is that when the baffle 10 moves, when the top block 22 moves beside the heat dissipation hole 4, the elastic force of the spring 21 pushes the top block 22 into the heat dissipation hole 4, pushing out the dust blocking the heat dissipation hole 4. When the inclined surface of the top block 22 contacts the inner wall of the heat dissipation hole 4, the inner wall of the heat dissipation hole 4 squeezes the top block 22, causing it to enter the limiting groove 20, and the spring 21 is compressed. Repeating this back and forth can clean the dust in the heat dissipation hole 4, enhancing the heat dissipation efficiency.

[0032] Working principle: When the device is no longer in use, the operator holds the grip rod 6 and then rotates the turntable 5. The turntable 5 drives the gear 9 to rotate through the connecting rod 14, and then drives the rack 8 to move. At this time, the T-shaped block 13 moves along the T-shaped groove 12. When the T-shaped block 13 moves from one end of the T-shaped groove 12 to the other end, the baffle 10 blocks the heat dissipation hole 4 at this time, making it difficult for external moisture to enter the housing 1. Finally, the operator rotates the rotating plate 7, and the rotating plate 7 drives the threaded rod 17 to rotate, and then makes the threaded rod 17 move along the threaded hole 16, thereby driving the abutting block 18 to move towards the housing 1 until the abutting block 18 contacts the housing 1. At this time, the abutting block 18 applies pressure to the housing 1, increasing the friction between the two, fixing the turntable 5 and preventing it from rotating. When the baffle 10 moves, when the top block 22 moves beside the heat dissipation hole 4, the elastic force of the spring 21 pushes the top block 22 into the heat dissipation hole 4, pushing out the dust blocking the heat dissipation hole 4. When the inclined surface of the top block 22 contacts the inner wall of the heat dissipation hole 4, the inner wall of the heat dissipation hole 4 squeezes the top block 22, causing it to enter the limiting groove 20, and the spring 21 is compressed. Repeating this back and forth can clean the dust in the heat dissipation hole 4, enhancing the heat dissipation efficiency.

[0033] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
