Description

Technical Field

[0001] The invention belongs to the technical field of photoelectric liquid level sensor application, and in particular relates to a water dispenser based on a photoelectric liquid level sensor. Background Art

[0002] With the improvement of living standards, water dispensers have become indispensable equipment in various places such as homes, offices, schools, shopping malls, stations, hospitals, small shops, factory workshops, etc., providing people with convenient room temperature water, cold water or hot water to meet various needs such as daily drinking water and brewing beverages. However, in the process of its widespread application, the problem of liquid level detection has gradually become prominent.

[0003] Traditional water dispensers mostly use float-type liquid level switches or electrode-type liquid level sensors. The float-type liquid level switch has a complex mechanical structure and is easily affected by scale, which causes the float to get stuck and makes it impossible to accurately detect the water level. The electrode-type liquid level sensor is prone to corrosion and has low detection accuracy. Both of them are difficult to accurately monitor and warn of the water level, and cannot effectively prevent dry burning, threatening the safe operation of the water dispenser.

[0004] To solve these problems, a Chinese patent with announcement number "CN119453751A" discloses a water dispenser based on a capacitive non-contact liquid level sensor. By installing a fixing plate and related components on the back of the water dispenser body, the position of the liquid level sensor can be flexibly adjusted, and an early warning is issued before the water level drops to a dangerous level, thereby improving safety to a certain extent. However, the device still has shortcomings. The sensor structure is arranged on the outside of the water dispenser as a whole, which not only affects the appearance, but is also easily damaged by accidental touch during use. Moreover, it can only perform simple linear displacement and cannot rotate around the bucket body for adaptation and adjustment. There are detection blind spots, and it is difficult to adapt to bucket bodies of different shapes and placement methods.

[0033] The carrying device 3 includes a movable mechanism 31, which is installed at the bottom of the water bucket bin 2. A water bucket body 32 is placed on the top of the movable mechanism 31. An adjustment mechanism 33 is fixedly installed in the middle of the top rear side of the movable mechanism 31. A rotating mechanism 34 is fixedly installed on the front of the adjusting mechanism 33. A sensor mechanism 35 is fixedly installed on the top of the rotating mechanism 34. The rotating mechanism 34 is covered on the outside of the water bucket body 32. During use, the water bucket body 32 can be placed on the top of the movable mechanism 31 of the carrying device 3. The movable mechanism 31 can move the water bucket body 32 into the water bucket bin 2. The adjustment mechanism 33 can be adjusted according to the height of the water bucket body 32. The motor in the adjustment mechanism 33 is started, and the motor drives the screw rod 333 to rotate. The screw rod 333 drives the movable block 334 to slide up and down in the vertical rail 331 through threaded transmission to adjust the height of the rotating mechanism 34. When the irradiation direction and position of the sensor mechanism 35 need to be adjusted, the motor in the rotating mechanism 34 runs, driving the gear 3414 to rotate, the gear 3414 meshes with the gear ring 3412, and the driving gear ring 3412 drives the slip ring 343 to slide in the annular rail 342, so that the sensor mechanism 35 can flexibly rotate around the outer side of the bucket body 32.

The magnetic plate 4 is fixed to the side of the hatch 5 close to the water dispenser body 1. When the hatch 5 is closed, the magnetic plate 4 and the water dispenser body 1 generate magnetic attraction, so that the hatch 5 fits tightly on the water dispenser body 1. Compared with traditional mechanical locks and other connection methods, this magnetic connection method has the advantage of simple operation, and users can Only need to gently bring the hatch 5 close to the water dispenser body 1, the magnetic plate 4 can be automatically adsorbed to complete the hatch 5 closing action; when opening the hatch 5, it is only necessary to apply appropriate external force to overcome the magnetic force of the magnetic plate 4 to easily open the hatch 5. In addition, the connection of the magnetic plate 4 can also effectively avoid problems such as the hatch 5 not being closed tightly due to wear and aging of mechanical parts, ensure that the interior of the water bucket warehouse 2 is relatively closed, reduce the entry of impurities such as dust, etc., play a certain protective role on the water bucket body 32, and also improve the overall aesthetics and ease of use of the water dispenser.

The adjustment mechanism 33 is fixedly installed in the middle of the top rear side of the receiving plate 313. The bucket body 32 is placed on the top of the receiving plate 313. During use, the guide rails 311 are firmly installed on both sides of the bottom of the bucket warehouse 2 to provide a basic framework for the operation of the entire movable mechanism 31. The slide plate 312 can slide flexibly inside the guide rail 311, and the sliding connection design between the two ensures the smooth movement of the slide plate 312. The receiving plate 313 fixedly installed on the top of the slide plate 312 is used The supporting bucket body 32 forms a stable placement platform. When the bucket body 32 needs to be moved into or out of the bucket compartment 2 of the water dispenser, it is only necessary to push the receiving plate 313. The receiving plate 313 drives the slide plate 312 to slide in the guide rail 311 to adjust the position of the bucket body 32. The adjustment mechanism 33 is installed in the middle of the rear side of the top of the receiving plate 313. It works together with the receiving plate 313, which can not only ensure the stability of the bucket body 32 during movement, but also cooperate with the receiving plate 313 when performing subsequent operations such as height adjustment of the sensor mechanism 35, to ensure the coordination and accuracy of the entire device when different functions are operated, laying the foundation for the water dispenser to efficiently and stably monitor the water level and other tasks.

[0036] refer to Figure 4-Figure 8The adjusting mechanism 33 includes a vertical rail 331, which is fixedly installed in the middle of the top rear side of the receiving plate 313. The bottom of the vertical rail 331 is fixedly connected to a first motor 332. The output end of the first motor 332 passes through the vertical rail 331 and is fixedly connected to a screw rod 333.

The adjusting mechanism 33 of the device cooperates with the rotating mechanism 34 to achieve precise adjustment of the position of the sensor mechanism 35. When the height of the sensor mechanism 35 needs to be adjusted, the first motor 332 in the adjusting mechanism 33 is started, and its output end drives the screw rod 333 to rotate in the vertical rail 331. Since the screw rod 333 is threadedly connected with the movable block 334, the rotation of the screw rod 333 drives the movable block 334 to slide up and down along the axial direction of the screw rod 333 in the vertical rail 331, thereby driving the rotating mechanism 34 connected thereto to achieve up and down displacement to adapt to the bucket body 32 of different heights. When the irradiation of the sensor mechanism 35 needs to be adjusted When the direction and position are determined, the rotating mechanism 34 plays a role. After the second motor 3413 of the driving component 341 in the rotating mechanism 34 is started, the output end drives the gear 3414 to rotate. Because the gear 3414 is meshed with the gear ring 3412, the gear 3414 rotates to drive the gear ring 3412 to rotate. The gear ring 3412 is fixed on the outside of the slip ring 343, thereby driving the slip ring 343 to slide and displace in the annular rail 342. The sensor mechanism 35 fixedly installed in the middle of the rear side of the top of the slip ring 343 can rotate flexibly around the bucket body 32 in all directions with the sliding rotation of the slip ring 343, so as to realize the detection of different positions of the bucket body 32 and ensure the comprehensiveness and accuracy of the water level detection.

[0037] refer to Figure 2-Figure 8The sensor mechanism 35 includes a mounting rail 351, which is fixedly mounted on the top of the slip ring 343. A limit assembly 352 is fixedly connected to one side of the mounting rail 351. A mounting block 353 is slidably connected inside the mounting rail 351.

The first photoelectric liquid level sensor 354 is electrically connected to the power socket of the water dispenser body 1 through a wire and a plug. The limit assembly 352 is snap-fitted with the mounting block 353. The limit assembly 352 includes a frame 3521 and a slot 3522. The frame 3521 is fixedly mounted on the middle of one side of the mounting rail 351. The limiting spring 357 is fixedly connected at equal intervals inside, the slot 3522 is opened on one side of the mounting rail 351 and the mounting block 353, the end of the limiting spring 357 is fixedly connected with the block 3523, the end of the block 3523 passes through the slot 3522 on the mounting rail 351 and is inserted into the slot 3522 of the mounting block 353, the outer side of the block 3523 is fixedly connected with a connecting shaft 3524, the outer end of the connecting shaft 3524 passes through the frame 3521 and is fixedly installed with a bridge handrail 3525, a threaded groove 356 is opened in the middle of the top of the receiving plate 313, the inner thread of the threaded groove 356 is connected with a second photoelectric liquid level sensor 355, and the second photoelectric liquid level sensor 355 is connected with the inner thread of the threaded groove 356. 55 is also electrically connected to the power socket of the water dispenser body 1 through a wire and a plug. During use, the first photoelectric liquid level sensor 354 and the second photoelectric liquid level sensor 355 are respectively electrically connected to the power socket of the water dispenser body 1 through a wire and a plug to obtain power support. The second photoelectric liquid level sensor 355 is installed in the thread groove 356 in the middle of the top of the receiving plate 313 through a threaded connection, which can stably detect the water level at the bottom of the bucket body 32. At the same time, its threaded connection design can facilitate the rapid disassembly and assembly of the second photoelectric liquid level sensor 355, making it convenient to use the device. The first photoelectric liquid level sensor 354 is installed on the top of the mounting block 353, and the mounting block 353 can slide in the mounting rail 351. When installing, the mounting block 353 can slide in the mounting rail 351. Insert block 353 into the mounting rail 351, loosen the bridge handrail 3525, and the limit spring 357 is reset to push the block 3523 to pass through the slot 3522 of the mounting rail 351 and insert it into the slot 3522 of the mounting block 353, so as to realize the limit connection between the mounting block 353 and the mounting rail 351, and complete the fixation of the first photoelectric liquid level sensor 354; when disassembling, pull the bridge handrail 3525, and the connecting shaft 3524 drives the block 3523 to move outward and out of the slot 3522. The mounting block 353 loses the limit and can be pulled out of the mounting rail 351.

[0038] Principle and advantages of use: This device can effectively optimize the user experience by setting a carrying device 3. In actual application scenarios, the bucket body 32 can be stably placed on the top of the receiving plate 313. At this time, the bucket body 32 is accurately positioned on the inner side of the annular rail 342. By pushing the slide plate 312 in the guide rail 311 and the receiving plate 313 inside it to slide, the receiving plate 313 can be easily moved into the bucket bin 2. It is particularly worth mentioning that during the entire use process, the sensor mechanism 35 is cleverly built into the water dispenser body 1. This design not only gives the device excellent protection and hiding functions, but also effectively prevents the sensor mechanism 35 from being physically damaged and contaminated by dust from the outside, thereby extending its use. The life span of the device is improved, and the overall aesthetics of the device is greatly improved. In addition, when it is necessary to adapt to the bucket body 32 of different heights, the first motor 332 can be started to operate. After the first motor 332 is running, its output shaft drives the screw rod 333 to rotate with high precision. During the rotation of the screw rod 333, the movable block 334 is driven to slide up and down smoothly on the inner side of the vertical rail 331 by relying on the principle of thread transmission. By accurately controlling the up and down displacement of the movable block 334, the height of the rotating mechanism 34 can be flexibly adjusted. This design enables the device to easily cope with bucket bodies 32 of various height specifications, further enhancing the adaptability during the overall use process and fully meeting the diverse use needs.

[0039] In actual use, when it is necessary to accurately adjust the irradiation direction and position of the sensor mechanism 35, the second motor 3413 can be conveniently started. After the second motor 3413 is running, its output shaft drives the gear 3414 to rotate at a high speed. Since the gear 3414 and the gear ring 3412 adopt a precise meshing connection method, the rotation of the gear 3414 can efficiently drive the gear ring 3412 to rotate synchronously. When the gear ring 3412 rotates, it drives the slip ring 343 connected thereto to slide smoothly on the inner side of the annular rail 342. By flexibly adjusting the sliding and rotation of the slip ring 343, The sensor mechanism 35 on the top can be accurately driven to rotate flexibly in all directions. This design enables the sensor mechanism 35 of the device to further realize flexible rotation adaptation on the basis of realizing height adjustment of the vertical rail 331. Through the organic combination of height adjustment and rotation adjustment, the sensor mechanism 35 can perform comprehensive and detailed adjustment detection for different heights of the bucket body 32 and various positions on the outside, effectively avoiding the occurrence of detection blind spots, greatly improving the adaptability of the device in actual use, and ensuring that the detection of the water level of the bucket body 32 is more accurate and reliable.

[0040] During the use of the device, the first photoelectric liquid level sensor 354 cooperates closely with the adjustment mechanism 33 and the rotating mechanism 34, and can perform all-round auxiliary detection of the outer surface of the bucket body 32, while the second photoelectric liquid level sensor 355 is precisely positioned at the bottom of the bucket body 32. The two work together to achieve high-precision and all-round detection of the water level in the bucket body 32. What is more important is that the design of this device fully considers the needs of convenient disassembly and assembly of the sensors. When it is necessary to disassemble the first photoelectric liquid level sensor 354 and the second photoelectric liquid level sensor 355, the operation process is clear and simple. For the second photoelectric liquid level sensor 355, first manually adjust and twist it to The second photoelectric liquid level sensor 355 can be easily and completely removed from the receiving plate 313 by separating it from the installation part and then pulling out the connecting plug. When removing the first photoelectric liquid level sensor 354, the operator can drive the connected connecting shaft 3524 to move horizontally by pulling the bridge handrail 3525. During the movement of the connecting shaft 3524, the card block 3523 can be synchronously pulled to move outward. After the card block 3523 moves outward to a certain position, it can be separated from the limiting constraint of the card slot 3522. During this process, the card block 3523 will squeeze the limiting spring 357. When the card block 3523 is completely separated from the card slot 3522, the mounting rail 351 and the mounting block 353 are The limiting relationship between them is released. At this time, the mounting block 353 can be smoothly pulled out from the inside of the mounting rail 351, thereby realizing the removal of the first photoelectric liquid level sensor 354 on the top of the mounting block 353. Conversely, when the first photoelectric liquid level sensor 354 and the second photoelectric liquid level sensor 355 need to be installed, the installation process is also simple and efficient. For the second photoelectric liquid level sensor 355, it is only necessary to accurately thread it into the thread groove 356 of the receiving plate 313 according to the thread matching relationship. For the first photoelectric liquid level sensor 354, first accurately insert the mounting block 353 into the inside of the mounting rail 351, and then release the bridge handrail 3525. At this time, the limiting spring 357 will quickly return to the original position. The clamping block 3523 is pushed into the clamping slot 3522 of the mounting rail 351 by its own elastic restoring force, and is accurately inserted into the clamping slot 3522 of the mounting block 353. The mounting block 353 can be firmly limited and mounted by the close mutual limiting action between the clamping block 3523 and the clamping slot 3522. This design enables the first photoelectric liquid level sensor 354 and the second photoelectric liquid level sensor 355 to be quickly and conveniently disassembled and assembled during actual use of the device. After the installation is completed, the power plug can be inserted. It can be seen that the device can effectively improve the convenience of the overall use of the device and provide users with a more efficient and user-friendly use experience.
