Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1: As Figure 1 - Figure 6As shown, this utility model provides a technical solution: an automatic water vending machine with a water leakage alarm function, including a vending machine body 1. The front of the vending machine body 1 is provided with an advertising screen 26, an intelligent display control screen 4, and a water receiving cavity 2. A water outlet 3 is provided at the top of the water receiving cavity 2. Ventilation vents 5 and air outlets 6 are provided on the sides of the vending machine body 1. Dustproof filter screens 7 are provided at both ventilation vents 5 and air outlets 6. The dustproof filter screens 7 are fixedly connected to the vending machine body 1 by fixing components 8. Mounting holes 23 are provided on the surface of the dustproof filter screens 7. A slot 18 is provided on the side of the main body 1 corresponding to the mounting hole 23. The fixing component 8 includes a locking block 801. A square groove 802 is provided at the bottom of the locking block 801. A first locking plate 803 and a second locking plate 805 are slidably connected inside the square groove 802. A spring 804 is fixedly connected between the first locking plate and the second locking plate 805. A first pressure plate 806 and a second pressure plate 807 are fixedly connected to the sides of the first locking plate 803 and the second locking plate 805. The bottom ends of the first locking plate 803 and the second locking plate 805 pass through the mounting hole 23 and are inserted into the slot 18. It is engaged with the slot 18. A water receiving trough 9 is provided at the bottom of the water receiving cavity 2. A support plate 12 is placed at the bottom of the water receiving cavity 2. A liquid level sensor 10 is fixedly connected to the side wall of the water receiving trough 9. An audible and visual alarm 11 is provided on the front of the water vending machine body 1. A drain pipe 13 is fixedly connected to the side wall of the water receiving trough 9. An electric control valve 14 is provided on one end of the drain pipe 13 located on the outside of the water vending machine body 1. The electric control valve 14, the liquid level sensor 10, and the audible and visual alarm 11 are all electrically connected to the circuit board inside the intelligent display control screen 4. There are two sets of fixing components 8. The fixed assembly 8 is symmetrically distributed on both sides of the middle part of the dust filter plate 7. The bottom four corners of the water vending machine body 1 are fixedly connected with the walking wheels 21 with self-locking structure. The inner side of the water vending machine body 1 is fixedly connected with the exhaust fan 15, which is located at the air outlet 6. The edge of the side of the dust filter plate 7 facing the water vending machine body 1 is fixedly connected with the sealing ring 17. The side of the dust filter plate 7 facing away from the water vending machine body 1 is provided with the limiting groove 22. The bottom of the locking block 801 is fixedly connected with the limiting rod 25, which is inserted into the limiting groove 22.

[0030] The beneficial effects achieved in this embodiment 1 are as follows: By setting the fixing component 8, it is convenient to assemble and disassemble the dustproof filter screen 7. When installing the dustproof filter screen 7, align the mounting hole 23 on the dustproof filter screen 7 with the slot 18 on the side of the water vending machine body 1, and then pass the bottom ends of the first card plate 803 and the second card plate 805 of the fixing component 8 through the mounting hole 23 and insert them into the slot 18. The elastic force of the spring 804 makes the first card plate 803 and the second card plate 805 tightly locked in the slot 18, thereby fixing the dustproof filter screen 7. When it is necessary to disassemble the dustproof filter screen 7, simply press the first pressure plate 806 and the second pressure plate 807 to make the first card plate 803 and the second card plate 805 move towards each other to compress the spring 804. 4. By removing the fixing component 8, the dust filter screen 7 can be easily removed. Compared to the placement using threaded fasteners, no additional tools are needed; the dust filter screen 7 can be disassembled and installed simply by pressing, greatly improving disassembly and assembly efficiency. This facilitates quick operation when the dust filter screen 7 needs cleaning or replacement, effectively solving problems such as untimely cleaning and clogged pores affecting ventilation, heat dissipation, and dust prevention caused by inconvenient disassembly in the past. This ensures a good working environment inside the water vending machine and the normal functioning of ventilation, heat dissipation, and dust prevention. By setting up a liquid level sensor 10, an audible and visual alarm 11, and an electric control valve 14, and these structures are electrically connected to the points inside the intelligent display control screen 4, when the water outlet 3... When a leak occurs, water flows into the water tank 9. The level sensor 10 detects that the water level has reached a threshold and sends a signal to the circuit board, triggering the electric control valve 14 to open and drain the accumulated water. At the same time, the audible and visual alarm 11 sounds an alarm, achieving a timely and effective leak alarm function. Two sets of fixing components 8 are symmetrically distributed on both sides of the middle of the dust filter plate 7. This symmetrical layout makes the dust filter plate 7 more evenly stressed when installed on the side of the water vending machine body 1, and can be more firmly fixed in the corresponding position. The four corners of the bottom of the water vending machine body 1 are fixedly connected with self-locking wheels 21, which facilitates the movement of the automatic water vending machine and allows it to be flexibly adjusted according to actual usage needs. The air outlet 6 is located on the inner side of the water vending machine body 1. The exhaust fan 15 actively guides airflow, accelerating the removal of heat generated by the operation of various components inside the water vending machine to the outside. Combined with the dust filter screens 7 at the vents 5 and air outlets 6, it effectively maintains a suitable temperature environment inside the water vending machine while ensuring relatively clean incoming air. This prevents problems such as decreased performance of electronic components and abnormal operation of the water-making equipment due to heat accumulation, ensuring the stable and efficient operation of the entire water vending machine. The sealing ring 17, fixedly connected to the edge of the dust filter screen 7 facing the water vending machine body 1, ensures a tight fit against the side of the water vending machine body 1 after the dust filter screen 7 is installed, filling any gaps between them and further preventing dust from entering the water vending machine from the surrounding area.The limiting rod 25 on the locking block 801 is inserted into the limiting groove 22 on the dust filter plate 7, which can prevent the possibility of displacement due to accidental collision when the fixing component 8 fixes the dust filter plate 7.

[0031] Example 2: As Figure 4 - Figure 6 As shown, anti-slip protrusions 24 are evenly provided on the pressing surfaces of the first pressure plate 806 and the second pressure plate 807. Several support rods 16 are fixedly connected to the edge of the side of the dust filter plate 7 facing the water vending machine body 1. Slots 19 are opened on the side of the water vending machine body 1 corresponding to the positions of the several support rods 16. The support rods 16 are inserted into the inside of the slots 19. A magnet 20 is fixedly connected to the bottom surface of the inside of the slots 19. The magnet 20 is magnetically connected to the support rods 16.

[0032] The beneficial effects achieved in this embodiment 2 are as follows: the anti-slip protrusions 24 evenly arranged on the pressing surfaces of the first pressure plate 806 and the second pressure plate 807 increase the friction between the fingers and the pressure plates. When pressing the pressure plates to disassemble the dust filter screen 7, the user can apply force more stably and easily, avoiding situations where the user cannot press down due to slippage or inconvenience in operation. With the cooperation of the support rod 16, the slot 19 and the magnet 20, the support rod 16 is inserted into the slot 19 and magnetically attracted to the magnet 20 of the slot 19. On the one hand, it plays a supporting role when installing the dust filter screen 7, making it easy to fix to the dust filter screen 7 through the fixing component 8. On the other hand, the magnetic attraction between the magnet 20 and the support rod 16 can further enhance the fit between the dust filter screen 7 and the side of the water vending machine body 1, and further improve the sealing effect of the sealing ring 17.

[0033] The working principle of this embodiment is as follows: When using the automatic water vending machine with a water leakage alarm function, firstly, air enters the water vending machine through the ventilation port 5. The dust filter screen 7 at the ventilation port 5 will filter dust and other impurities in the air to prevent them from entering the water vending machine in large quantities and affecting the normal operation of various components. The dust filter screen 7 is fixed to the side of the water vending machine body 1 by the fixing component 8. During installation, align the mounting hole 23 on the dust filter screen 7 with the slot 18 on the side of the water vending machine body 1, and pass the bottom ends of the first and second clips 803 and 805 of the fixing component 8 through the mounting hole 23. Under the elastic force of the spring 804, the first clip 803 and the second clip 805 are inserted into the slot 18 and locked in place, thus achieving fixation. At the same time, the support rod 16 fixedly connected to the edge of the dust filter screen 7 is inserted into the slot 19 on the side of the water vending machine body 1 and magnetically attracted to the magnet 20 in the slot 19, further stabilizing the installation position of the dust filter screen 7 and enhancing the sealing performance. When the water vending machine generates heat due to water production, electronic component operation, etc., the exhaust fan 15 located at the air outlet 6 starts to work. It drives air to be discharged from the air outlet 6, thereby forming airflow, accelerating the dissipation of heat inside the water vending machine, and maintaining a suitable internal temperature environment. During daily use, if the water outlet 3 experiences any issues, the exhaust fan 15 will not be able to dissipate heat. In case of leakage, water will flow into the water receiving tank 9 at the bottom of the water receiving cavity 2. The liquid level sensor 10 on the side wall of the water receiving tank 9 will monitor the water level change in real time. Once the water level reaches the set warning value, the liquid level sensor 10 will transmit the signal to the circuit board inside the intelligent display control screen 4. The circuit board will then control the sound and light alarm 11 to sound an alarm to alert the surrounding personnel. At the same time, it will control the electric control valve 14 at the outer end of the drain pipe 13 located on the outside of the water vending machine body 1 to open and drain the water in the water receiving tank 9. When it is necessary to clean or replace the dust filter screen 7, press the first pressure plate 806 and the second pressure plate 807. The anti-slip protrusions 24 on the pressure plates facilitate stable force application. Pressing causes the first clamping plate 803 and the second clamping plate 805 to move towards each other and compress the spring 804. The clamping plate will disengage from the clamping slot 18, and the dust filter screen 7 can be easily removed. After that, it can be cleaned or replaced accordingly. Then, reinstall the dust filter screen 7 according to the above installation steps to ensure that the water vending machine continues to operate normally. Furthermore, the self-locking wheels 21 at the bottom of the water vending machine can be moved and positioned according to actual needs, facilitating the use and layout adjustment of the equipment.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
