[0002] With the continuous development of science and technology and the popularization of smart devices, payment terminals, as a smart terminal device, are widely used in various industries. Payment terminals are convenient and fast to use, which greatly improves work efficiency and user experience. However, as the frequency of use of payment terminal devices increases, due to long-term operation and environmental pollution, payment terminal devices are easily affected by pollutants such as dust and debris, resulting in poor heat dissipation inside the machine, reduced working performance, and even failure. Therefore, how to effectively prevent dust and debris from entering the interior of the payment terminal device and maintain the normal operation and stability of the device has become a technical problem that needs to be solved urgently.

[0003] During the use of the dust-proof filtering device, the internal components of the payment terminal equipment will generate heat due to long-term use, so the equipment needs to be effectively cooled, and dust prevention is also required at the same time to dissipate heat. Otherwise, external dust will easily enter the equipment and adhere to the components, causing poor heat dissipation of the internal components of the equipment and causing malfunctions. Utility Model Content

When the heat generated inside the terminal device is too much, the exhaust fan will quickly extract and discharge the heat inside the device, while the heat dissipation holes for dissipating the heat are blocked by the protective cover, so that external dust cannot directly enter the device from the heat dissipation holes. The dust needs to float upward from the air outlet at the bottom into the protective cover, and then refract and fall on the heat dissipation holes. The heat inside the terminal device is discharged outward from the heat dissipation holes, and it is difficult for dust to enter the device from the heat dissipation holes. The device can effectively block dust and impurities in the air from entering the interior of the payment terminal, protect the interior of the device from pollution, extend the service life of the device, and ensure long-term stable operation of the device.

[0026] Example 1: Please refer to Figures 1 to 5 :

[0027] The utility model proposes a dust-proof filtering device for heat dissipation of a payment terminal, comprising: a payment terminal device 1; a cash box is placed in the inner cavity of the payment terminal device 1; coins inserted from the upper port of the payment terminal device 1 will enter the cash box inside, and two threaded grooves are provided at the upper end of the rear side wall of the payment terminal device 1; a through shaft hole is provided in the middle of the rear end of the payment terminal device 1; the rotating shaft of the exhaust fan 202 passes through the shaft hole of the payment terminal device 1, and the fan blade 203 is installed at the rear end of the inner cavity of the payment terminal device 1, and two threaded holes are provided on the rear side wall of the payment terminal device 1; a guardrail 101 is fixedly installed at the rear end of the inner cavity of the payment terminal device 1; the guardrail 101 blocks the front end of the fan blade 203 to prevent the fan blade 203 from rotating and touching the inner cavity of the payment terminal device 1 The payment terminal device 1 has components in the inner part, and a frame groove 102 is provided at the edge of the rear side wall; the payment terminal device 1 has evenly distributed heat dissipation holes 103 provided on the rear side wall; the payment terminal device 1 uses the components in the inner cavity for a long time, and the heat in the payment terminal device 1 will be discharged outward from the heat dissipation holes 103, and universal wheels 104 are respectively installed at the four corners of the bottom of the payment terminal device 1; the installation of the universal wheels 104 facilitates the pushing of the entire device, and a fixing seat 2 is fixedly installed at the lower end of the shaft hole of the payment terminal device 1, and a groove is provided at the upper end of the fixing seat 2; a protective cover 3 is installed on the rear side wall of the payment terminal device 1, and the protective cover 3 protects the exhaust fan 202, so that external objects will not come into contact with the exhaust fan 202, thereby protecting the exhaust fan 202.

[0028] Among them, a support plate 201 is fixedly installed on the bottom of the fixing seat 2, and screws are installed at both ends of the support plate 201. The screws on the support plate 201 are rotated and inserted into the two threaded holes on the rear side wall of the payment terminal device 1 to fix and support the support plate 201 and the fixing seat 2, so that the fixing seat 2 can stably support the exhaust fan 202, and the exhaust fan 202 will not fall from the fixing seat 2 when it is running. The exhaust fan 202 is fixedly installed in the groove of the fixing seat 2. When the exhaust fan 202 is started, the fan blades 203 on the rotating shaft will rotate rapidly. The rotation of the fan blades 203 will extract the heat in the payment terminal device 1, and the extracted heat will be discharged outward from the heat dissipation holes 103 at the rear end of the fan blades 203. At this time, the heat in the payment terminal device 1 will be quickly The temperature of the payment terminal device 1 is reduced, which effectively reduces the temperature of the payment terminal device 1, ensures the normal operation of the equipment, and avoids malfunctions caused by overheating. A circle of fan blades 203 is fixedly installed on the rotating shaft of the exhaust fan 202, and a retaining ring 204 is fixedly installed on the front end of the rotating shaft of the exhaust fan 202. The exhaust fan 202 runs to extract the heat in the payment terminal device 1 and discharge it outward from the heat dissipation holes 103, and then discharges the heat outward from the air outlet 302. It is difficult for external dust to pass through the air outlet 302 and enter the payment terminal device 1 from the heat dissipation holes 103. When the payment terminal device 1 is in normal use, after the protective cover 3 is installed, the external dust needs to float upward from the air outlet 302 at the bottom of the protective cover 3, and the dust is blocked by the heat dissipation holes 103 and is also difficult to enter the payment terminal device 1.

[0029] Among them, a card frame 301 is fixedly installed at the edge of the front side wall of the protective cover 3. When installing the protective cover 3, the card frame 301 is first inserted into the frame groove 102, and then the screws on the hanging plate 303 are rotated and inserted into the threaded groove at the upper end of the rear side wall of the payment terminal device 1 to fix and restrict the hanging plate 303 and the protective cover 3. At this time, the protective cover 3 will not fall off when touched. The bottom of the protective cover 3 is evenly provided with penetrating air holes 302, and the heat discharged outward from the heat dissipation holes 103 will enter the protective cover 3 and then be discharged outward from the air holes 302 at the lower end. The top of the protective cover 3 is fixedly installed with a hanging plate 303, and the two ends of the hanging plate 303 are respectively rotatably inserted with penetrating screws. The rear end of the inner wall of the protective cover 3 is provided with mutually symmetrical guide grooves 304, and the rear end of the protective cover 3 is slidably installed with a dustproof plate 305, and the two side walls of the dustproof plate 305 are respectively fixedly installed with The guide bar 306 is slidably installed in the guide groove 304. When the dustproof plate 305 slides up and down, the guide bar 306 is restricted by the guide groove 304, and the dustproof plate 305 can only slide up and down to prevent the dustproof plate 305 from being offset or tilted when sliding up and down. The dustproof plate 305 cannot block the heat dissipation hole 103, and a baffle plate 307 is fixedly installed on the top of the dustproof plate 305. The baffle plate 307 is supported at the top of the protective cover 3, and the dustproof plate 305 will not slide down from the protective cover 3. The top of the baffle plate 307 is fixedly installed with symmetrical handles 308. When the heat of the inner cavity of the payment terminal device 1 is excessive after long-term use, the handle 308 is grasped to lift the dustproof plate 305 upwards, and the heat dissipation hole 103 is exposed. The heat in the payment terminal device 1 is directly discharged outward from the heat dissipation hole 103, and is not blocked or restricted by the dustproof plate 305, thereby greatly improving the heat dissipation effect.

[0030] Embodiment 2, based on embodiment 1, as Figure 1 and Figure 5 As shown, a support plate 201 is fixedly installed at the bottom of the fixing base 2, and penetrating screws are installed at both ends of the support plate 201. The support plate 201 and the screws are all removed, and then the front side wall of the fixing base 2 is fixedly welded to the rear side wall of the payment terminal device 1 to restrict the fixing base 2. In this way, the exhaust fan 202 will not shake during operation, and the problem of screws loosening due to long-term use is avoided, while also saving parts costs.

[0031] The working principle of this embodiment is as follows: when in use, the fan blades 203 on the rotating shaft of the exhaust fan 202 are started to rotate rapidly, and the rotation of the fan blades 203 will extract the heat in the payment terminal device 1, and the extracted heat will be discharged outward from the heat dissipation holes 103 at the rear end of the fan blades 203. At this time, the heat in the payment terminal device 1 will be quickly reduced, and then the heat will be discharged outward from the air outlet 302. It is difficult for external dust to pass through the air outlet 302 and enter the payment terminal device 1 from the heat dissipation holes 103. When the payment terminal device 1 is used for a long time, When there is too much heat in the inner cavity, grab the handle 308 and lift the dustproof plate 305 upwards. At this time, the heat dissipation holes 103 will be exposed, and the heat in the payment terminal device 1 will be discharged directly to the outside from the heat dissipation holes 103 without being blocked by the dustproof plate 305, thereby greatly improving the heat dissipation effect. When the payment terminal device 1 is in normal use, after the protective cover 3 is installed, the external dust needs to float upwards from the air outlet 302 at the bottom of the protective cover 3. The dust is blocked by the heat dissipation holes 103 and it is difficult for the dust to enter the payment terminal device 1.
