Description

Technical Field

[0001] This invention relates to the field of payment equipment technology, and in particular to a QR code scanning and broadcasting payment device. Background Technology

[0002] With the widespread adoption of mobile payments, QR code scanning has become a mainstream transaction method in numerous scenarios, including retail, catering, and transportation. To enhance transaction transparency and user experience, QR code payment terminals with integrated voice broadcast functions are widely used in various checkout scenarios. After scanning, these devices can automatically announce the payment amount and transaction result, effectively preventing missed scans and incorrect payments, and enhancing information interaction between users and merchants.

[0003] There are already various integrated devices with scanning and voice broadcasting functions in the existing technology. For example, patent CN113379981A discloses a QR code scanning payment voice broadcasting device and method. The device includes an image acquisition module, a main control processing unit, and a voice broadcasting module. It can scan the payment QR code on the user's mobile phone through a camera, and after decoding, trigger a voice broadcasting of the payment amount and result, realizing automated feedback of the payment process.

[0004] However, in practical applications, it has been found that the device described in the prior art generates continuous heat in its internal electronic components, such as the image sensor and main control chip, under prolonged continuous operation. This heat can lead to thermal noise in the image sensor, causing the captured QR code image to become blurry, have increased noise, or decrease in contrast. The recognition rate is significantly reduced, or even impossible, especially in low-light or highly reflective environments. Simultaneously, the main control chip may become unstable, experience processing delays, or malfunctions at high temperatures, affecting decoding efficiency and status judgment, leading to delayed, repetitive, or incorrect voice broadcasts, thus impacting transaction smoothness. Furthermore, continuous high temperatures accelerate component aging, shorten equipment lifespan, and increase maintenance costs. Summary of the Invention

[0005] To overcome the problems mentioned in the background art, the present invention provides a QR code scanning and broadcasting payment device.

[0006] The technical solution is as follows: A QR code scanning and broadcasting payment device includes a housing, a glass panel, a control terminal, a scanning unit, and a flow guide shell fixedly connected to the housing. An electric fan is fixedly connected to the flow guide shell. The housing has a through hole for gas to enter the housing. The housing has a speaker hole, and a fixing ring is fixedly connected to the speaker hole. A loudspeaker is fixedly connected to the fixing ring. The control terminal is connected to the scanning unit, the electric fan, and the loudspeaker. The fixing ring has a vent hole located between the loudspeaker and the speaker hole on the housing, for guiding gas to exit from the speaker hole on the housing.

[0007] More preferably, the surface of the glass is coated with a nanoscale hydrophobic and oleophobic coating.

[0008] More preferably, a one-way valve is installed in the vent hole of the fixing ring.

[0009] More preferably, a sponge is fixed inside the flow guide shell, and the sponge is located between the electric fan and the through hole.

[0010] More preferably, the sponge is fixed with a plurality of heat-conducting pillars, which penetrate the sidewall of the housing.

[0011] More preferably, the heat-conducting pillar is made of brass.

[0012] More preferably, it also includes a conduit fixed to the housing, the housing having a plurality of air guide holes, the conduit being used to connect the flow guide shell to the plurality of air guide holes, the air guide holes being used to guide gas to blow through the glass.

[0013] More preferably, it also includes a cylindrical shell, which is fixedly connected to the housing. The cylindrical shell is slidably provided with a sliding plug, and the cylindrical shell and the sliding plug cooperate to form a cavity. The cylindrical shell is slidably provided with a sliding rod, and the housing is equipped with a button. The sliding rod is used to press the button, and the button is signal-connected to the control terminal. The button is used to control the start and stop of the electric fan.

[0014] More preferably, the cylindrical shell and the sliding plug cooperate to form a cavity filled with a liquid medium with a large coefficient of volume expansion.

[0015] More preferably, the cylindrical shell is slidably provided with a sliding frame, a spring is fixedly connected between the sliding frame and the cylindrical shell, the cylindrical shell is fixedly connected with a fixing frame, the fixing frame is rotatably provided with a gear, and the fixing frame is slidably provided with two centrally symmetrical racks, both racks meshing with the gear, and the two racks are respectively fixedly connected to the sliding frame and the sliding rod.

[0016] The present invention has the following advantages: 1. This invention activates an electric fan to guide airflow to blow on the control terminal, effectively removing the heat generated during its operation, thereby maintaining the control terminal within a suitable temperature range, ensuring its stable operation, and preventing the control terminal from aging due to high temperature. At the same time, the gas is discharged from the speaker hole of the housing, preventing dust and impurities in the air from clogging the speaker hole of the housing, and ensuring the clarity of the voice broadcast by the speaker. 2. By setting up a sponge to absorb moisture in the air, heat dissipation is achieved while preventing moisture from entering the equipment. This effectively avoids short circuits, component corrosion, or performance degradation caused by moisture condensation, further ensuring the long-term stable operation of the control terminal in complex environments. 3. By guiding gas through the conduit and air vent, the gas is blown onto the glass to prevent condensation from forming on the glass surface due to temperature differences or moisture accumulation. This keeps the surface clean and transparent, ensuring that the scanning unit can clearly recognize the QR code, effectively improving the recognition accuracy and the working stability of the equipment in humid environments. 4. The temperature inside the cylindrical shell is monitored in real time by the liquid medium inside the shell. When the temperature inside the shell reaches the set threshold, the electric fan is activated for automatic heat dissipation. When the temperature inside the shell drops to the set threshold, the electric fan is turned off. The intermittent operation of the electric fan during this process effectively reduces the wear and power consumption of the fan itself, extends its service life, and reduces the risk of heat dissipation failure due to fan failure. At the same time, it reduces the operating noise of the equipment and improves the user experience, especially in quiet environments or continuous trading scenarios. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Example 1: A QR code scanning and broadcasting payment device, referring to... Figures 1-4 As shown, the device includes a housing 1, to which a glass 2, a control terminal 3, a scanning unit 4, and a flow guide shell 5 are fixedly connected. The surface of the glass 2 is coated with a nano-level hydrophobic and oleophobic coating to reduce water droplet adhesion and facilitate accurate QR code recognition by the scanning unit 4. An electric fan 51 is fixedly connected to the flow guide shell 5, which has a filter screen that is angled and located in front of the electric fan 51. The filter screen is used to intercept impurities in the air. The housing 1 has a through hole 6 for gas from the flow guide shell 5 to enter the housing 1. The housing 1 is provided with a speaker hole, and a fixing ring 7 is fixedly connected to the speaker hole of the housing 1. A speaker 71 is fixedly connected to the fixing ring 7. The control terminal 3 is connected to the scanning unit 4, the electric fan 51 and the speaker 71 respectively. The fixing ring 7 is provided with a vent hole for installing a one-way valve. The one-way valve on the fixing ring 7 is used to allow external gas to enter it. The vent hole of the fixing ring 7 is located between the speaker 71 and the speaker hole on the housing 1, and is used to guide the gas out from the speaker hole of the housing 1 to avoid impurities clogging the speaker hole of the housing 1, thereby ensuring that the speaker 71 broadcasts clear sound.

[0021] Reference Figure 2 and Figure 4 As shown, a sponge 8 is fixed inside the airflow guide shell 5. The sponge 8 is used to absorb moisture in the air and reduce the amount of moisture entering the shell 1. The sponge 8 is located between the electric fan 51 and the through hole 6. Multiple heat-conducting columns 9 are fixed to the sponge 8. The heat-conducting columns 9 penetrate the side wall of the shell 1. The upper part of the heat-conducting columns 9 is located inside the shell 1. The heat-conducting columns 9 are made of brass. The heat-conducting columns 9 use the heat inside the shell 1 to dry the sponge 8.

[0022] Reference Figure 2 and Figure 3 As shown, it also includes a conduit 10, which is fixed to the housing 1. The conduit 10 is close to the control terminal 3, so that the gas flowing in the conduit 10 can carry away the heat generated by the control terminal 3. The housing 1 has multiple air guide holes 11. The conduit 10 is used to connect the flow guide shell 5 with the multiple air guide holes 11. The air guide holes 11 are used to guide the gas to blow through the glass 2, further ensuring that the scanning unit 4 can accurately identify the QR code through the glass 2.

[0023] Working principle: When using the device, first turn on the power to operate the device, then the electric fan 51 works. The electric fan 51 guides the outside air into the guide shell 5 and through the sponge 8. The sponge 8 absorbs the moisture in the gas. Then the dehumidified gas is divided into two parts, and the two parts of gas pass through the through hole 6 and the conduit 10 respectively.

[0024] Gas enters the housing 1 through the through hole 6, and then exits through the vent on the fixed ring 7 and the speaker hole of the housing 1, forming a continuous airflow. The flowing air carries away the heat inside the housing 1, preventing the control terminal 3 from aging due to high temperature, and achieving heat dissipation for the control terminal 3. At the same time, the flowing gas exits through the speaker hole of the housing 1, preventing the speaker hole of the housing 1 from becoming blocked, and ensuring the clarity of the voice broadcast by the speaker 71.

[0025] The gas passing through the conduit 10 is discharged through the air vent 11. The discharged gas blows across the glass 2, keeping its surface clean and transparent, ensuring that the scanning unit 4 can clearly recognize the QR code. When water droplets are attached to the surface of the glass 2, the gas blowing action causes the water droplets to flow downwards, improving the recognition accuracy of the scanning unit 4.

[0026] When a payment is required, the user places the QR code in front of the glass 2, the scanning unit 4 works to perform the payment, and the speaker 71 announces the payment amount.

[0027] Example 2: Based on Example 1, referring to... Figure 4 and Figure 5 As shown, it also includes a cylindrical shell 12, which is fixed inside the housing 1. A sliding plug 13 is slidably disposed inside the cylindrical shell 12. There is damping between the sliding plug 13 and the cylindrical shell 12. The cylindrical shell 12 and the sliding plug 13 cooperate to form a chamber filled with alcohol medium. The alcohol medium has a large volume expansion coefficient, which facilitates efficient identification of temperature changes inside the housing 1. A sliding rod 14 is slidably disposed on the lower part of the cylindrical shell 12. A button 15 is installed on the housing 1. The sliding rod 14 is used to press the button 15. The button 15 is connected to the control terminal 3 and is used to control the start and stop of the electric fan 51.

[0028] Reference Figure 4 and Figure 5 As shown, a sliding frame 16 is slidably disposed on the upper part of the cylindrical shell 12. A spring 17 is fixedly connected between the sliding frame 16 and the cylindrical shell 12. The spring 17 is sleeved on the sliding frame 16. A fixing frame 18 is fixedly connected to the side of the cylindrical shell 12. A gear 19 is rotatably disposed on the fixing frame 18. Two centrally symmetrical racks 20 are slidably disposed on the fixing frame 18. Both racks 20 mesh with the gear 19. The two racks 20 are fixedly connected to the sliding frame 16 and the sliding rod 14 respectively.

[0029] Working principle: In the initial state of using the device, the electric fan 51 is not working. If the scanning unit 4 does not perform QR code recognition at this time, the electrical components in the device are all in standby mode. At this time, the heat generated by the electrical components in the device is relatively small. When the scanning unit 4 continues to work, the heat generated by the electrical components in the device gradually increases. With the accumulation of heat, the temperature inside the housing 1 gradually rises. At this time, the heat inside the housing 1 is transferred to the liquid medium inside through the cylindrical shell 12. The liquid medium gradually expands due to the heat and squeezes the sliding plug 13 to move downward. When the temperature inside the housing 1 reaches the set threshold, the sliding plug 13 moves and squeezes the sliding rod 14 to press the button 15. The button 15 is pressed and starts the electric fan 51 through the control terminal 3.

[0030] The electric fan 51 repeats the heat dissipation operation in Embodiment 1. As the heat dissipation operation proceeds, the temperature inside the housing 1 gradually decreases. During this process, the liquid medium inside the cylindrical shell 12 gradually cools down and contracts, causing the sliding plug 13 to gradually move upward. When the temperature inside the housing 1 decreases to the set threshold, the sliding plug 13 presses the sliding frame 16 upward and compresses the spring 17. The upward movement of the sliding frame 16 causes the sliding rod 14 to move downward through the gear 19 and two racks 20, pressing the button 15 again. The button 15 is pressed and turns off the electric fan 51 through the control terminal 3. If the temperature rises to the set threshold again, the above operation is repeated.

[0031] The intermittent operation of the electric fan 51 during this process effectively reduces the wear and power consumption of the fan itself, extends its service life, reduces equipment operating noise, and improves the user experience. In addition, intermittent start-stop can save energy, improve the overall energy efficiency, and achieve more intelligent, stable and environmentally friendly temperature control management.

[0032] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
