Currently, the structural design of dining tables is relatively simple, and their function is limited to eating. With social development and the continuous improvement of people's consumption levels, smart furniture is gaining popularity in the furniture market.

[0003] For example, Chinese Utility Model Patent Application No. CN202220446478.7 discloses a dining table with a disinfection cabinet, which includes a tabletop and supporting legs. The supporting legs are fixedly connected to the bottom of the tabletop, supporting the tabletop. The inner side of the supporting legs has a placement cavity and several tableware baskets. Several fixing blocks are provided inside the placement cavity, and these fixing blocks are respectively fixedly connected to the supporting legs. Fixing plates are provided on both sides of each tableware basket, and these fixing plates are integrally formed with the tableware baskets. The fixing plates are placed on the fixing blocks, so that the tableware baskets are positioned within the placement cavity. Several disinfection devices are provided inside the placement cavity, installed at the bottom of the placement cavity. Heat-insulating paper is provided inside the placement cavity, positioned at the bottom of the disinfection devices. This utility model's dining table with a disinfection function is convenient for users and saves time and space.

[0004] However, the aforementioned dining table with a sterilizer has the following technical problems: 1. The sterilizer and tableware basket are both located under the tabletop's support legs, occupying a significant amount of space and making it inconvenient for guests to move their feet under the table. Furthermore, guests' feet are prone to bumping into the sterilizer, posing a safety hazard. 2. Guests need to squat down to retrieve food from the sterilizer, which is inconvenient. 3. The dining table has a limited function, only providing a platform for eating and tableware, which is somewhat restrictive. Utility Model Content

[0005] The purpose of this utility model is to provide an intelligent self-service dining system, which aims to solve the technical problem in the prior art where the disinfection device of the disinfection cabinet table is set under the support leg of the tabletop, which occupies a large amount of space under the tabletop, making the space under the tabletop cramped and inconvenient for guests to move their feet under the tabletop, and taking up a lot of space.

[0006] To achieve the above objectives, this utility model provides an intelligent self-service dining system, including a dining table, dining chairs, a disinfection cabinet, and a lifting device; at least one dining chair is provided next to the dining table, the lifting device is provided above the dining table, the disinfection cabinet is provided on the lifting device and located above the dining table, and the lifting device is used to drive the disinfection cabinet to rise and suspend it in the air or drive the disinfection cabinet to descend and approach the tabletop.

[0007] Compared with the prior art, the above-mentioned one or more technical solutions in the intelligent self-service dining system provided by the embodiments of this utility model have at least one of the following technical effects:

[0008] 1. When guests are dining at the table, the sterilizing cabinet is lowered to the tabletop via a lifting device. Guests can then retrieve their tableware from the cabinet without the need for staff, saving manpower. After guests have retrieved their tableware, the cabinet is raised again and suspended in the air, eliminating the need to place it under the table and saving space on the table and floor. This significantly improves space utilization and practicality, and ensures guests' safety by preventing their feet from touching the cabinet.

[0009] 2. The disinfection cabinet is equipped with ultraviolet disinfection lamps and infrared disinfection lamps to provide ultraviolet sterilization and high-temperature disinfection functions, achieving dual disinfection functions, greatly improving disinfection efficiency and effect, and ensuring the cleanliness and hygiene of the tableware inside.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0032] In one embodiment of this utility model, reference is made to Figures 1-9 This invention provides an intelligent self-service dining system, including a dining table 100, a dining chair 200, a disinfection cabinet 300, and a lifting device 400.

[0033] The dining table 100 is provided with at least one dining chair 200 on each side. Specifically, at least one dining chair 200 is provided on each of the opposite sides of the dining table 100, which can provide dining for multiple people.

[0034] Among them, reference Figure 1 A lifting device 400 is provided above the dining table 100. The disinfection cabinet 300 is located above the lifting device 400. The lifting device 400 is used to drive the disinfection cabinet 300 to rise and suspend it in the air or to drive the disinfection cabinet 300 to descend and approach the tabletop of the dining table 100.

[0035] Specifically, refer to Figure 1 When guests use table 100 for dining, the lifting device 400 lowers the disinfection cabinet 300 to a position close to the tabletop. Guests can then retrieve their tableware from the cabinet without the need for service staff, saving manpower. After guests have retrieved their tableware, the lifting device 400 raises the disinfection cabinet 300, suspending it in the air. This eliminates the need to place the cabinet under the table, saving space and floor space, significantly improving space utilization and practicality. Furthermore, guests' feet will not touch the cabinet, ensuring high safety.

[0036] In another embodiment of this utility model, referring to Figure 2 and Figure 3The lifting device 400 includes a first fixing mechanism 410, a second telescopic mechanism 420, a third telescopic mechanism 430, a fourth telescopic mechanism 440, and a main transmission mechanism 450.

[0037] Among them, reference Figures 2-9 The first fixing mechanism 410 is used to fix it to the ceiling of the house. The first fixing mechanism 410 has a first storage cavity 411, the second telescopic mechanism 420 has a second storage cavity 421, and the third telescopic mechanism 430 has a third storage cavity 431. The second telescopic mechanism 420 is disposed within the first storage cavity 411, and the second telescopic mechanism 420 can extend or retract along the direction of the first storage cavity 411. The third telescopic mechanism 430 is disposed within the second storage cavity 421, and the third telescopic mechanism 430 can extend or retract along the direction of the second storage cavity 421. The fourth telescopic mechanism 440 is disposed within the third storage cavity 431, and the fourth telescopic mechanism 440 can extend or retract along the direction of the third storage cavity 431.

[0038] Among them, reference Figures 2-9 A first transmission mechanism 600 connects the first fixed mechanism 410, the second telescopic mechanism 420, and the third telescopic mechanism 430. A second transmission mechanism 700 connects the second telescopic mechanism 420, the third telescopic mechanism 430, and the fourth telescopic mechanism 440. The fourth telescopic mechanism 440 is connected to the disinfection cabinet 300. The main transmission mechanism 450 connects the first fixed mechanism 410 and the second telescopic mechanism 420 and drives the second telescopic mechanism 420 to extend or retract along the direction of the first storage cavity 411. The third telescopic mechanism 430 follows the second telescopic mechanism 420 to extend or retract along the direction of the second storage cavity 421 via the first transmission mechanism 600, and the fourth telescopic mechanism 440 follows the second telescopic mechanism 420 to extend or retract along the direction of the third storage cavity 431 via the second transmission mechanism 700, realizing multi-stage telescopic movement to lift the disinfection cabinet 300 and suspend it in the air or drive the disinfection cabinet 300 to descend and approach the tabletop of the dining table 100.

[0039] Therefore, refer to Figures 2-9 By setting up a first fixed mechanism 410, a second telescopic mechanism 420, a third telescopic mechanism 430, a fourth telescopic mechanism 440, and a main transmission mechanism 450, a multi-stage stepped retraction or extension action is achieved. This allows the fourth telescopic mechanism 440 to retract into the third telescopic mechanism 430, the third telescopic mechanism 430 to extend into the second telescopic mechanism 420, and the second telescopic mechanism 420 to extend into the first fixed mechanism 410. The structure is compact, and while ensuring the telescopic length, it does not require a large frame corresponding to the extension length. This makes the lifting device 400 small in size when retracted, occupying little suspension space, saving space, and facilitating installation.

[0040] Furthermore, referring to Figure 3 and Figure 4 The main transmission mechanism 450 includes a mounting plate 451, a motor 452, a transmission component 455, and a first lead screw 453. The mounting plate 451 is located in the first receiving cavity 411. The first lead screw 453 is vertically mounted, and its top is rotatably connected to the mounting plate 451 via a bearing. The motor 452 is located on the mounting plate 451 and connected to the first lead screw 453 via the transmission component 455, driving the first lead screw 453 to rotate. A first lead screw nut 454 is fitted onto the first lead screw 453, and the first lead screw nut 454 is fixedly connected to the second telescopic mechanism 420. The motor 452 drives the first lead screw 453 to rotate, causing the first lead screw nut 454 to move up and down along the first lead screw 453, thereby causing the second telescopic mechanism 420 to extend or retract along the direction of the first receiving cavity 411. The structure is simple.

[0041] Furthermore, referring to Figure 3 and Figure 4 The transmission component 455 includes two first transmission wheels 456 and a first transmission bar 457. The two first transmission wheels 456 are respectively located on the top of the first lead screw 453 and the rotating shaft of the motor 452. The first transmission bar 457 is adapted to be installed on the two first transmission wheels 456 to form a transmission structure, so that the motor drives the first lead screw 453 to rotate through the transmission component 455.

[0042] Specifically, refer to Figure 3 and Figure 4 When the first drive wheel 456 is a sprocket, the first drive bar 457 is a drive chain. When the first drive wheel 456 is a synchronous belt pulley, the first drive bar 457 is a synchronous belt.

[0043] Furthermore, referring to Figure 3 A vibration damping and noise reduction cotton 470 is provided between the motor 452 and the first fixing mechanism 410. The vibration damping and noise reduction cotton 470 is used to reduce the vibration and noise when the motor 452 is driven. The vibration damping and noise reduction cotton 470 can be made of sponge.

[0044] Furthermore, referring to Figure 3 The motor 452 is equipped with an outer cover 458, which serves to protect against dust and provide sound insulation.

[0045] Among them, reference Figure 3 , Figure 5 and Figure 6The first fixing mechanism 410 includes a first top plate 412 and multiple first side plates 413. The multiple first side plates 413 are respectively disposed on the four sides of the first top plate 412. A first storage cavity 411 is formed between the first top plate 412 and the multiple first side plates 413. A mounting plate 451 is fixed to the bottom of the first top plate 412 by multiple connecting rods.

A motor is fixed to the mounting part 451a.

[0046] Furthermore, referring to Figure 3 , Figure 5 and Figure 6 Each of the multiple first side plates 413 has a first guide plate 415 on its inner side, and the first guide plate 415 has a first guide groove 416. The second telescopic mechanism 420 includes a second top plate 422 and multiple second side plates 423. The multiple second side plates 423 are respectively disposed on the four sides of the second top plate 422, and a second storage cavity 421 is formed between the second top plate 422 and the multiple second side plates 423. Each of the multiple second side plates 423 has a first guide block 424 on its outer side, and the multiple first guide blocks 424 are respectively connected to the multiple first guide grooves 416, and the first guide blocks 424 can move along the direction of the first guide grooves 416. The lower end of the first lead screw 453 is movably inserted through the second top plate 422, and the first lead screw nut 454 is fixedly connected to the second top plate 422. The main drive mechanism 450 is used to provide the main drive power when retracting or extending. The first guide block 424 and the first guide groove 416 play a guiding role, driving the second telescopic mechanism 420 to stably extend or retract along the direction of the first receiving cavity 411, and the movement is stable.

[0047] Furthermore, the second top plate 422 is provided with a second through hole 437, the screw 244 is provided in the second through hole 437, and the first lead screw nut 454 is fixed in the second through hole 437.

[0048] Among them, reference Figure 3 , Figure 6 and Figure 7 Each of the inner surfaces of multiple second side plates 423 is further provided with a second guide plate 425, and each of the two second guide plates 425 is provided with a second guide groove 426. The third telescopic mechanism 430 includes multiple third side plates 432. The multiple third side plates 432 are connected in sequence, forming a third receiving cavity 431 between the multiple third side plates 432. Each of the outer surfaces of the multiple third side plates 432 is provided with a second guide block 433, and the multiple second guide blocks 433 are respectively connected to the multiple second guide grooves 426, and the second guide blocks 433 can move along the direction of the second guide grooves 426. The second guide blocks and the second guide grooves 426 play a guiding role, so that the third telescopic mechanism 430, through the first transmission mechanism 600, follows the second telescopic mechanism 420 to stably extend or retract along the direction of the second receiving cavity 421, and the movement is stable.

[0049] Furthermore, referring to Figure 3 , Figure 7 Figure 8 Each of the multiple third side plates 432 has a third guide plate 434 on its inner side, and each third guide plate 434 has a third guide groove 435. The fourth telescopic mechanism 440 includes multiple fourth side plates 442. The multiple fourth side plates 442 are connected in sequence. Each of the multiple fourth side plates 442 has a third guide block 443 on its outer side. The multiple third guide blocks 443 are respectively adapted to and connected to the multiple third guide grooves 435, and the third guide blocks 443 can move along the direction of the third guide grooves 435. The third guide blocks 443 cooperate with the third guide grooves 435 to play a guiding role, so that the fourth telescopic mechanism 440, through the second transmission mechanism 700, follows the second telescopic mechanism 420 to stably extend or retract along the direction of the third storage cavity 431, and the movement is stable.

[0050] Reference Figure 6 The first transmission mechanism 600 includes two first transmission components 601. The two first transmission components 601 are respectively disposed on both sides of the second telescopic mechanism 420. Each first transmission component 601 includes a first chain 610 and two first sprockets 620. The upper and lower sides of the second side plate 423 of the second telescopic mechanism 420 are provided with first through holes 427. The two first sprockets 620 are rotatably connected to the two first through holes 427 respectively via first connecting rods 621. The first chain 610 is adapted to be fitted onto the two first sprockets 620 to form a transmission structure. The first chain 610 located on the outer side of the second side plate 423 is fixedly connected to the first side plate 413 of the first fixing mechanism 410 via a fixing member 611. The first chain 610 located on the inner side of the second side plate 423 is fixedly connected to the third side plate 432 of the third telescopic mechanism 430 via a fixing member 611. When the main transmission mechanism 450 drives the second telescopic mechanism 420 to extend or retract along the direction of the first storage cavity 411, the second telescopic mechanism 420 drives the first chain 610 to move (rotate) on the first sprocket 620. Thus, the first chain 610 pulls the third telescopic mechanism 430 to follow the second telescopic mechanism 420 to extend or retract along the direction of the second storage cavity 421, forming a linkage of actions to achieve multi-stage telescopic motion with a compact structure.

[0051] Reference Figure 7The second transmission mechanism 700 includes two second transmission components 701. The two second transmission components 701 are respectively located on both sides of the third telescopic mechanism 430. Each second transmission component 701 includes a second chain 710 and two second sprockets 720. The upper and lower sides of the third side plate 432 of the third telescopic mechanism 430 are provided with second through holes 437. The two second sprockets 720 are rotatably connected to the two second through holes 437 via second connecting rods 721. The second chain 710 is adapted to be fitted onto the two second sprockets 720 to form a transmission structure. The second chain 710 located on the outer side of the third side plate 432 is fixedly connected to the second side plate 423 of the second telescopic mechanism 420 via a fixing member 611. The second chain 710 located on the inner side of the third side plate 432 is fixedly connected to the fourth side plate 442 of the fourth telescopic mechanism 440 via a fixing member 611. When the main transmission mechanism 450 drives the second telescopic mechanism 420 to extend or retract along the direction of the first storage cavity 411, the second telescopic mechanism 420 drives the first chain 610 to move (rotate) on the first sprocket 620. This causes the first chain 610 to pull the third telescopic mechanism 430 to follow the second telescopic mechanism 420 in extending or retracting along the direction of the second storage cavity 421. The third telescopic mechanism 430 drives the second chain 710 to move (rotate) on the second sprocket 720. This causes the second chain 710 to pull the fourth telescopic mechanism 440 to follow the second telescopic mechanism 420 in extending or retracting along the direction of the third storage cavity 431. This creates a linkage mechanism, achieving multi-stage telescopic motion with a compact structure.

[0052] Among them, reference Figure 3 The lifting device 400 also includes a control box 460. The main drive mechanism 450 is electrically connected to the control box 460. The control box 460 can be configured using a PLC or integrated chip according to actual production needs. Since the control box 460 is a mature and established technology, how the control box 460 controls the operation of the lifting device 400 should be well known and mastered by those skilled in the art. Therefore, the control principle of this utility model will not be described in detail here.

[0053] In another embodiment of this utility model, referring to Figure 3 and Figure 9The disinfection cabinet 300 includes a cabinet body 301. The cabinet body 301 is connected to a fourth telescopic mechanism 440. The cabinet body 301 has a first placement cavity 302, which contains multiple placement baskets 303 for placing tableware. The top of the first placement cavity 302 has at least one infrared disinfection lamp 360 and at least one ultraviolet disinfection lamp 370. The infrared disinfection lamp 360 provides infrared high-temperature disinfection, and the ultraviolet disinfection lamp 370 provides ultraviolet sterilization. The top of the cabinet body 301 has a blower 350 and an air inlet communicating with the first placement cavity 302. The air outlet of the blower 350 is connected to the air inlet.

[0054] Specifically, refer to Figure 3 and Figure 9 By setting up ultraviolet disinfection lamps 370 and infrared disinfection lamps 360 to provide ultraviolet sterilization and high-temperature disinfection functions, dual disinfection functions are achieved, which greatly improves disinfection efficiency and effect, and ensures the cleanliness and hygiene of the tableware inside. Combined with the setting of blower 350 to provide air drying and to make the high temperature generated by infrared disinfection lamps 360 circulate within the disinfection cabinet body 301, the disinfection and drying efficiency is improved.

[0055] Furthermore, referring to Figure 3 and Figure 9 The disinfection cabinet body 301 includes a cabinet body 310 and a frame 320. The cabinet body 310 covers the frame 320, the first placement cavity 302 is located in the frame 320, and the blower 350 is located on the top of the cabinet body 310. Both the cabinet body 310 and the frame 320 are connected to a lifting device. Specifically, the top of the cabinet body 310 is symmetrically provided with connecting frames 340, which are connected to the second telescopic mechanism 420 and can slide up and down relative to the second telescopic mechanism 420. The top of the frame 320 is fixedly connected to the fourth telescopic mechanism 440.

[0056] Specifically, refer to Figure 1 , Figure 3 and Figure 9 When the lifting device 400 drives the disinfection cabinet 300 to rise, the cabinet body 310 moves downward relative to the frame 320 and covers the frame 320. That is, when the fourth telescopic mechanism 440 retracts into the third storage cavity 431 of the third telescopic mechanism 430, the fourth telescopic mechanism 440 pulls the frame 320 upward and stores it inside the cabinet body 310, so that the cabinet body 310 covers the frame 320, facilitating subsequent disinfection of the tableware inside the frame 320. When the lifting device 400 drives the disinfection cabinet 300 to descend, the cabinet body 310 moves upward relative to the frame 320 and exposes the frame 320. That is, the fourth telescopic mechanism 440 extends out of the third storage cavity 431 of the third telescopic mechanism 430, and the fourth telescopic mechanism 440 pushes the frame 320 out of the cabinet body 310, exposing the frame 320, making it convenient for guests to retrieve tableware from the frame 320.

[0057] Therefore, refer to Figure 1 , Figure 3 and Figure 9 When the lifting device 400 drives the disinfection cabinet 300 to rise to the top, the cabinet body 310 covers the frame 320 to disinfect the tableware inside the frame 320. When the lifting device 400 drives the disinfection cabinet 300 to descend to the bottom, the frame 320 is exposed for guests to retrieve the tableware. Furthermore, the frame 320 is exposed in all four directions, allowing guests to retrieve tableware from all four sides, greatly improving convenience.

[0058] Furthermore, referring to Figure 3 and Figure 9 Each of the two connecting frames 340 is provided with at least one sliding block 341. The second telescopic mechanism 420 has vertically arranged sliding rods 342 on opposite sides. The sliding blocks 341 are slidably connected to the corresponding sliding rods 342, allowing the cabinet 310 to slide up and down relative to the second telescopic mechanism 420. The sliding blocks 341 and sliding rods 342 cooperate to provide guidance, making the movement of the cabinet 310 more stable and improving the efficiency of the operation. A limiting block 343 is also provided at the bottom of the sliding rod 342, restricting the sliding block 341 from sliding out of the sliding rod 342.

[0059] Furthermore, referring to Figure 3 and Figure 9 The bottom of the disinfection cabinet body 301 is equipped with multiple ambient lights 380. The light from the multiple ambient lights 380 illuminates the dining table, greatly enhancing the atmosphere during the meal and thus improving the dining experience for guests.

[0060] Preferred, refer to Figure 3 and Figure 9 The bottom of the disinfection cabinet body 301 is equipped with multiple ambient lights 380 of varying lengths. When multiple ambient lights 380 of varying lengths emit light simultaneously, they present a layered lighting effect, which greatly enhances the atmosphere during the meal and thus greatly improves the dining experience for guests.

[0061] Among them, reference Figure 3 and Figure 9 The disinfection cabinet body 301 also includes a control component 330. The ultraviolet disinfection lamp 370, the infrared disinfection lamp 360, and the blower 350 are all electrically connected to the control component 330. In this embodiment, the control component 330 can be configured using a PLC or integrated chip according to actual production needs. Since the control component 330 is a mature and established technology, how it controls the disinfection cabinet should be well-known and mastered by those skilled in the art; therefore, its control principle will not be described in detail here.

[0062] In another embodiment of this utility model, referring to Figure 10 and Figure 11 The dining table 100 includes table legs 101 and a tabletop 110 located on the upper part of the table legs. The lower surface of the tabletop 110 has at least one function panel 140, which includes at least one faucet 142, a charging socket 143, and a sterilizer lift switch 146. The faucet 142 is connected to a water supply system or water tank (not shown) via a water pipe and is used to provide drinking water to guests; this drinking water can be hot, warm, or cold. The charging socket 143 is used to charge guests' electronic devices.

[0063] Among them, reference Figure 10 and Figure 11 The disinfection cabinet lifting switch 146 is electrically connected to the control box 460, and is used to control the disinfection cabinet 300 to rise or fall. When a guest needs tableware, the lifting device 400 is controlled by the disinfection cabinet lifting switch 146 to drive the disinfection cabinet 300 down to the tabletop, at which point the guest can take out the required tableware from the disinfection cabinet 300. After taking out the tableware, the lifting device 400 is controlled by the disinfection cabinet lifting switch 146 to drive the disinfection cabinet 300 up and suspend it in the air, making operation convenient.

[0064] Furthermore, referring to Figure 10 and Figure 11 The function panel 140 also includes at least one hook 144 and at least one seat sensor 145. The hook 144 is for guests to hang their belongings, making it convenient for guests to place their items. The seat sensor 145 is used to detect guests to indicate that the table is occupied. Specifically, the seat sensor 145 is a position sensor, which is a mature existing technology.

[0065] Furthermore, the tabletop panel 110 is equipped with a QR code for ordering food (not shown in the figure), which is used by customers to order food and is easy to operate.

[0066] Furthermore, referring to Figures 10-12 A movable frame 120 and a drive assembly 130 are slidably provided on the lower end surface of the desktop panel 110. Specifically, the movable frame 120 is horizontally slidably provided on the lower end surface of the desktop panel 110. The movable frame 120 has a placement position 121, which is adapted to place a trash can 124. The drive assembly 130 is used to drive the movable frame 120 to move so that the trash can 124 is stored under the desktop panel 110 or moved out of the desktop panel 110. Specifically, when the drive assembly 130 drives the movable frame 120 to move inward to the desktop panel 110, it causes the trash can 124 to be stored under the desktop panel 110; when the drive assembly 130 drives the movable frame 120 to move outward to the desktop panel 110, it causes the trash can 124 to be moved out of the desktop panel 110.

[0067] Specifically, refer to Figures 10-12 When a customer needs to dispose of trash, the drive assembly 130 moves the trash can 124 out of the tabletop 110, exposing the trash can 124, making it convenient to dispose of trash. After disposal, the drive assembly 130 retracts the trash can 124 under the tabletop 110, concealing it from the customer's view and improving the dining experience. Furthermore, the trash can 124 can be removed from its placement position 121 for easy and time-saving cleaning.

[0068] Furthermore, referring to Figure 12 The placement position 121 is a placement frame, and the upper frame opening of the placement position 121 is a cone-shaped opening 122 that is larger at the top and smaller at the bottom. The trash can 124 is cone-shaped, larger at the top and smaller at the bottom, and is fitted into the cone-shaped opening 122 so that the trash can 124 is positioned in the cone-shaped opening 122, making it convenient to put and take out the trash can 124.

[0069] Furthermore, referring to Figure 12 The conical opening 122 is evenly provided with multiple buffer pads 123, which buffer the collision between the trash can 124 and the placement frame.

[0070] Furthermore, referring to Figure 12 The lower end face of the desktop panel 110 is symmetrically provided with two linear slide rods 125. The two ends of the linear slide rods 125 are fixed to the desktop panel 110 through connecting seats 126. At least one slider 127 is slidably provided on each of the two linear slide rods 125. One end of the moving frame 120 is fixedly connected to the sliders 127 on the two linear slide rods 125 on both sides, so that the moving frame 120 is stably slidably connected to the lower end face of the desktop panel 110, and the structure is stable.

[0071] Furthermore, referring to Figures 10-12 The function panel 140 is equipped with a trash can switch 141, which is electrically connected to the drive assembly 130. The trash can switch 141 is used to control the movement of the drive assembly 130. In use, the guest controls the movement of the drive assembly 130 through the trash can switch 141, thereby driving the moving frame 120 to move, which in turn moves the trash can 124 out of the tabletop 110 or stores it under the tabletop 110, making it convenient to use.

[0072] Furthermore, referring to Figures 10-12The drive assembly 130 includes a second lead screw 131 and a motor 132. The two ends of the second lead screw 131 are rotatably connected to the lower end face of the desktop 110 via bearing seats 133. A second lead screw nut 134 is connected to the second lead screw 131, and the second lead screw nut 134 is fixedly connected to the slider 127 or the movable frame 120. The motor 132 is mounted on the desktop 110, and the shaft of the motor 132 is fixedly connected to one end of the second lead screw 131. The motor 132 drives the second lead screw 131 to rotate, causing the second lead screw nut 134 to reciprocate along the second lead screw 131, thereby causing the movable frame 120 to reciprocate, thus allowing the trash can 124 to be stored under the desktop 110 or moved outside the desktop 110. The structure is simple.

[0073] In summary, the dining table 100 provides charging for guests' electronic devices via the charging socket 143, provides drinking water for guests via the faucet 142, facilitates guests to dispose of trash in the trash can 124 via the trash can switch 141, allows guests to place items via the hook 144, and enables guests to automatically order food via the ordering QR code, making the dining table highly functional and practical.

[0074] The dining table 100 includes an electronic control device (not shown in the figure). The drive assembly 130, trash can switch 141, seat sensor 145, and disinfection cabinet switch 146 are all electrically connected to the electronic control device. In this embodiment, the electronic control device can be configured using a PLC or integrated chip according to actual production needs. Since the electronic control device is a mature and established technology, how it controls the operation of the dining table should be well-known and mastered by those skilled in the art. Therefore, its control principle will not be described in detail here.

[0075] In another embodiment of this utility model, referring to Figures 14-17 The dining chair 200 includes a chair frame 201 and a seat 210. The chair frame 201 can be a support frame of any shape and structure, as long as it can stably support the seat 210, and is not limited here.

[0076] Among them, reference Figure 15 and Figure 16 The upper end of the chair frame 201 is provided with an inclined slide rail 220, so that the front end of the slide rail 220 is lower than the rear end of the slide rail 220. In a specific embodiment, the slide rail 220 is preferably a linear guide rail. At least one slider 221 is slidably provided on the slide rail 220, and the chair seat 210 is disposed on the slider 221 and can move back and forth along the slide rail 220.

[0077] Among them, reference Figure 15 and Figure 16The chair frame 201 is also provided with a reset member 230, which has the tendency to drive the seat 210 to move backward along the slide rail 220. When a guest sits on the seat 210, the guest's own weight drives the seat 210 to move forward along the slide rail 220.

[0078] Specifically, refer to Figures 15-4 When in use, the guest sits on the chair 210. The guest's weight acts on the chair 210 and drives it to move forward along the slide rail 220. The chair 210 moves forward and approaches the dining table 100, allowing the guest to dine at a suitable distance from the dining table 100. When the guest gets up and leaves the chair 210, the reset component 230 drives the chair 210 to move backward along the slide rail 220. The chair 210 moves backward and away from the dining table 100, creating a sufficiently wide distance between the chair 210 and the dining table 100. This allows the guest to move between the chair 210 and the dining table 100 without having to manually pull or push the chair, making it convenient to use and greatly improving the guest's dining experience.

[0079] Reference Figure 15 In order to make the seat 210 stably mounted on the chair frame 201, the upper end of the chair frame 201 is provided with two inclined slide rails 220. The seat 210 is mounted on the sliders 221 of the two slide rails 220 so that the seat 210 can move back and forth stably on the two slide rails 220.

[0080] Furthermore, referring to Figure 15 and Figure 16 The upper end of the chair frame 201 is provided with an upper limit block 201 and a lower limit block 202 on the side of the slide rail 220. Specifically, the upper limit block 201 and the lower limit block 202 are fixed to the chair frame 201 with screws, which is convenient for installation. The slider 221 is connected to or connected to a moving block 222 through the connecting block 240. The moving block 222 is located between the upper limit block 201 and the lower limit block 202. When the moving block 222 abuts against the lower limit block 202, it is used to limit the travel of the chair seat 210 forward along the slide rail 220. That is, when the moving block 222 abuts against the lower limit block 202, it is the maximum travel of the chair seat 210 forward along the slide rail 220. When the moving block 222 abuts against the upper limit block 201, it is used to limit the travel of the chair seat 210 backward along the slide rail 220. That is, when the moving block 222 abuts against the upper limit block 201, it is the maximum travel of the chair seat 210 backward along the slide rail 220. Therefore, the seat 210 moves back and forth along the slide rail 220 within a reasonable range.

[0081] Furthermore, referring to Figure 15 and Figure 16 Both the upper limit block 201 and the lower limit block 202 are fitted with a buffer sleeve 203. The buffer sleeve 203 contacts the moving block 222. The buffer sleeve 203 can buffer the direct collision between the moving block 222 and the limit block or the lower limit block 202, reducing collision noise and wear.

[0082] The cushioning sleeve 203 can be made of rubber or silicone, etc., and has a good cushioning effect.

[0083] Furthermore, referring to Figure 15 and Figure 16 The upper end of the chair frame 201 is provided with a tilting platform 204, and the slide rail 220 is tilted on the tilting platform 204 so that the slide rail 220 is tilted at the upper end of the chair frame 201, which facilitates the installation of the slide rail 220. Specifically, the slide rail 220 can be fixed to the tilting platform 204 by means of screwing or welding, etc., and the installation is firm.

[0084] Furthermore, referring to Figure 15 and Figure 16 A support plate 205 is provided at the lower position of the tilting platform 204. The support plate 205 supports the lower end of the slide rail 220, providing support for the slide rail 220 and further increasing the sturdiness of the slide rail 220 installed on the tilting platform 204. Specifically, the support plate 205 can be fixed to the upper end of the chair frame 201 by means of screwing or welding.

[0085] Furthermore, referring to Figure 15 and Figure 16 The slider 221 is provided with a connecting block 240, the upper end surface of which is set as a horizontal surface 241. The chair seat 210 is fixed on the horizontal surface 241 so that the chair seat 210 is fixed on the connecting block 240, thereby fixing the chair seat 210 on the slider 221, which facilitates installation. Specifically, the chair seat 210 is fixed on the horizontal surface 241 by means of screwing or welding.

[0086] Furthermore, referring to Figure 15 and Figure 16 The reset component 230 is a gas spring. One end of the gas spring is connected to the chair frame 201, and the other end is connected to the chair seat 210. When the chair seat 210 moves forward along the slide rail 220, the chair seat 210 pushes the piston rod of the gas spring to compress the gas inside the cylinder of the gas spring. When the guest gets up and leaves the chair seat 210, the gas inside the cylinder is in a compressed state, and the cylinder pushes the piston rod to reset. The piston rod of the gas spring pushes the chair seat 210 to move backward along the slide rail 220, so that the chair seat 210 returns to its initial position. The structure is simple and the movement is stable.

[0087] Furthermore, referring to Figure 15 and Figure 16Each end of the gas spring is provided with a screw 231. Both the chair frame 201 and the seat 210 are provided with a connector 250, and both connectors 250 have connecting holes 251 passing through them. The two screws 231 pass through the two connecting holes 251 respectively. Two nuts 232 are threaded onto each screw 231, clamping the two sides of a connector 250 to connect the two ends of the gas spring to the two connectors 250 respectively. By tightening the nuts 232, the position of the gas spring can be finely adjusted so that the extension and retraction direction of the gas spring piston rod is consistent with the movement direction of the chair frame 201 along the slide rail 220, ensuring smooth movement and structural stability.

[0088] In another embodiment of this utility model, referring to Figure 14 and Figure 15 The upper rear side of the chair frame 201 is provided with a backrest 260, which is used to support the back of the guest and improve the comfort of the guest.

[0089] Among them, reference Figure 15 The lower edge of the seat 210 is provided with a surrounding plate 211 so that the seat 210 is in the shape of a cover. The surrounding plate 211 covers the slide rail 220 and the reset component 230, making it less likely for the hand to touch the slide rail 220 and the reset component 230, thus improving safety.

[0090] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.
