DETAILED DESCRIPTION

[0039] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0040] The present invention provides the following preferred embodiments: Embodiment 1, as Figure 1-Figure 12 As shown, a self-service tea brewing vending machine includes a cabinet 11, a brewing box 14, a brewing tank 15, an operation panel 13, a storage mechanism, a brewing mechanism and a pressing mechanism. The operation panel 13 is installed on one side of the cabinet 11. A control switch is provided on the operation panel 13. The control switch is electrically connected to the controller. The brewing box 14 is located inside the cabinet 11. The brewing tank 15 is opened on the surface of the brewing box 14 and communicated with the inner cavity of the brewing box 14. The surface of the cabinet 11 is provided with a window that matches the brewing tank 15. Specifically, a limit seat 67 is installed inside the brewing tank 15. The limit seat 67 can be used to limit the water cup, thereby improving the stability of the water cup placement and ensuring the accuracy of the water cup placement position. When in use, the customer can place the water cup inside the limit seat 67, and then select and purchase tea through the operation panel 13.

[0041] In actual use, a storage basket for storing disposable water cups may be provided on the outer wall of the cabinet 11 to facilitate customers.

[0042] The storage mechanism includes a replacement component, multiple storage tanks 58 and multiple material discharge components. The multiple storage tanks 58 are installed inside the cabinet 11 and located above the brewing box 14. Each material discharge component is installed at the bottom end of a storage tank 58. The replacement component is located between the cabinet 11 and the multiple storage tanks 58. The replacement component is used to replace the position of the storage tank 58 so that the storage tank 58 storing the required tea bags can be moved above the avoidance hole 19. By using the material discharge component, each time a tea bag is put in, only one tea bag can be put in at a time, which can achieve quantitative delivery of tea bags to meet usage requirements.

[0043] The brewing mechanism includes a guide hopper 30, a water outlet pipe 24, a conversion component and a conveying component. The top of the cabinet 11 is provided with an avoidance hole 19 connected to the brewing tank 15. The water outlet pipe 24 and the guide hopper 30 are symmetrically arranged at the top of the brewing box 14. The conversion component is located between the brewing box 14, the water outlet pipe 24 and the guide hopper 30. The conveying component is installed below the brewing box 14. One end of the conveying component is connected to the water outlet pipe 24. The conveying component is used to convey hot water to the water outlet pipe 24. In the initial state, the guide hopper 30 is located above the avoidance hole 19. The guide hopper 30 can be used to guide the tea bag so that the tea bag can accurately pass through the avoidance hole 19 and fall into the inside of the teacup. Subsequently, the positions of the guide hopper 30 and the water outlet pipe 24 are exchanged through the conversion component, so that the water outlet pipe 24 can be located above the avoidance hole 19. The hot water can be output through the water outlet pipe 24 through the conveying component, so that the hot water can flow into the inside of the teacup to achieve brewing of tea.

[0044] The pressing mechanism includes a pressing plate 48, a swinging assembly, a transmission assembly, a flushing assembly and a plurality of water-permeable holes 49. The pressing plate 48 is located inside the brewing box 14. The plurality of water-permeable holes 49 are equidistantly arranged on the surface of the pressing plate 48. The swinging assembly is installed between the pressing plate 48 and the brewing box 14. The swinging assembly is used to realize the rotation of the pressing plate 48. The transmission assembly is located between the swinging assembly and the exchange assembly. The flushing assembly is located between the conveying assembly and the brewing tank 15.

[0045] During the conversion process between the guide hopper 30 and the water outlet pipe 24, the transmission component is used to enable the conversion component to drive the swing component to work synchronously, that is, while the guide hopper 30 and the water outlet pipe 24 are converted, the pressing plate 48 can be screwed into the interior of the teacup. During the water filling process, the pressing plate 48 extending into the interior of the teacup can limit and block the tea bag, thereby preventing the tea bag from floating on the water surface too easily due to its weight and resulting in poor soaking effect. This can effectively extend the soaking time of the tea bag, improve the brewing effect of the tea bag, and enhance the taste of the brewed tea.

[0046] By providing a flushing component, the flushing component can be used to flush the surface of the pressing plate 48 before and after brewing the tea bag, thereby ensuring the cleanliness of the surface of the pressing plate 48, effectively preventing the residual tea on the pressing plate 48 from affecting the next brewing of the tea bag, and improving the taste of the brewed tea.

[0047] like Figure 1-Figure 12 As shown, the exchange assembly includes a swing rod 25, a central shaft 26, a first gear 27, a first rack 28, a first electric push rod 29 and a connecting plate 68. The central shaft 26 is rotatably set on the brewing box 14, the swing rod 25 is fixedly installed on the top of the central shaft 26, and the two ends of the swing rod 25 are respectively connected to the water outlet pipe 24 and the guide hopper 30. The first gear 27 is located below the swing rod 25 and fixed on the surface of the central shaft 26. The first rack 28 slides on the top of the brewing box 14, and the first rack 28 and the first gear 27 are meshed with each other. The first electric push rod 29 is installed on the brewing box 14, and the output end of the first electric push rod 29 is connected to one end of the connecting plate 68, and the other end of the connecting plate 68 is connected to one end of the first rack 28.

[0048] When the positions of the material guide hopper 30 and the water outlet pipe 24 need to be adjusted, the first electric push rod 29 is controlled by the controller to work, and the first electric push rod 29 can drive the first rack 28 to slide above the brewing box 14 through the connecting plate 68. Since the first rack 28 and the first gear 27 are meshed with each other, when the first rack 28 moves, it can drive the first gear 27 to rotate, so that the swing arm 25 can rotate through the central axis 26, so that the swing arm 25 can drive the material guide hopper 30 and the water outlet pipe 24 to rotate, so that the positions of the material guide hopper 30 and the water outlet pipe 24 can be exchanged.

[0049] like Figure 1-Figure 12 As shown, the transmission assembly includes a cam 32, a rotating wheel 33, an adapter seat 34, a first guide rod 35, a limit block 36 and a spring 37.

The first guide rod 35 is slidably set on the limit block 36. One end of the first guide rod 35 is connected to the adapter seat 34. The rotating wheel 33 is rotatably set on the adapter seat 34. The rotating wheel 33 abuts against the surface of the cam 32. The spring 37 is sleeved on the outside of the first guide rod 35. The two ends of the spring 37 are respectively connected to the adapter seat 34 and the limit block 36.

[0050] In the initial state, the rotating wheel 33 contacts the base circle portion of the cam 32 , the flange portion of the cam 32 is located on the side of the cam 32 away from the rotating wheel 33 , the spring 37 is in a natural state, and the top of the adapter 34 is slidably connected to the inner wall of the brewing box 14 .

[0051] When the central shaft 26 rotates, the central shaft 26 can drive the cam 32 to rotate, so that the flange portion of the cam 32 can abut against the surface of the rotating wheel 33. At this time, the first guide rod 35 moves inside the limit block 36 toward the side away from the rotating wheel 33, and the spring 37 is compressed.

[0052] like Figure 1-Figure 12 As shown, the swing assembly includes a first connecting rod 38, a second guide rod 39, a second rack 40, a first guide rail 41, a second gear 42, a mounting plate 43, a turntable 44, an insertion rod 45, a swing frame 46 and a strip groove 47. The mounting plate 43 is fixedly mounted on the bottom of the inner cavity of the brewing box 14, the second gear 42 is rotatably arranged on one side of the mounting plate 43, the first guide rail 41 is fixed to the inside of the brewing box 14, the second rack 40 is slidably arranged inside the first guide rail 41, the second rack 40 and the second gear 42 are meshed with each other, one end of the first connecting rod 38 is fixedly connected to one end of the first guide rod 35 away from the adapter 34, the other end of the first connecting rod 38 is connected to the second guide rod 39, and the other end of the second guide rod 39 is connected to the second rack 40.

[0053] When the first guide rod 35 moves toward the side away from the rotating wheel 33, the first guide rod 35 can drive the second guide rod 39 to move through the first connecting rod 38, so that the second rack 40 can slide inside the first guide rail 41. Since the first guide rail 41 and the second gear 42 are meshingly connected, when the second rack 40 moves, it can drive the second gear 42 to rotate on the mounting plate 43.

[0054] The turntable 44 is located on the side of the mounting plate 43 away from the second gear 42. The turntable 44 and the second gear 42 are coaxially fixedly connected, that is, when the second gear 42 rotates, it can drive the turntable 44 to rotate synchronously. One end of the swing frame 46 is connected to the top of the pressure plate 48, and the other end of the swing frame 46 is hinged to the inside of the brewing box 14. The strip groove 47 is opened on the surface of the swing frame 46, one end of the insertion rod 45 is inserted into the inside of the strip groove 47, and the other end of the insertion rod 45 is fixedly connected to the turntable 44.

[0055] When the turntable 44 rotates with the rotation of the second gear 42, the turntable 44 can drive the insertion rod 45 to rotate. Since the insertion rod 45 is inserted into the inside of the strip groove 47, when the insertion rod 45 rotates, it can drive the swing frame 46 to swing, so that the pressure plate 48 at one end of the swing frame 46 can swing synchronously, so that the pressure plate 48 can rotate to the inside of the water cup, realizing the function of limiting and blocking the tea bag, which can effectively prolong the soaking time of the tea bag during the tea bag brewing process and improve the brewing effect of the tea bag.

[0056] like Figure 1-Figure 12As shown, the conveying assembly includes a water tank 20, a first pump body 21, a hose 22, a connecting pipe 23 and an arc-shaped avoidance groove 31. The arc-shaped avoidance groove 31 is opened through the brewing box 14. The water tank 20 is located below the brewing box 14 and is installed inside the cabinet 11. The first pump body 21 is installed on the top of the water tank 20.

The connecting pipe 23 slides inside the arc-shaped avoidance groove 31, one end of the connecting pipe 23 is connected to the water outlet pipe 24, and the other end of the connecting pipe 23 is connected to the hose 22.

[0057] The arc-shaped avoidance groove 31 can be used to limit and guide the connecting pipe 23 . When the water outlet pipe 24 and the guide hopper 30 are replaced, the water outlet pipe 24 can drive the connecting pipe 23 to move inside the arc-shaped avoidance groove 31 .

[0058] It should be noted that a heating system for heating water is provided inside the water tank 20. The heating system is a prior art and will not be described in detail here.

[0059] When water needs to be poured into the teacup, the controller controls the first pump body 21 to work, and the hot water in the water tank 20 is transported to the water outlet pipe 24 through the hose 22 and the connecting pipe 23, and water is poured into the water cup through the water outlet pipe 24 to complete the brewing of the tea bag.

[0060] like Figure 1-Figure 12 As shown, the exchange component includes a transverse plate 53, a motor 54, a third gear 55, a fourth gear 56 and a main shaft 57.

[0063] The second electric push rod 64 is installed at the bottom end of the U-shaped plate 61, and the output end of the second electric push rod 64 is connected to one end of the second connecting rod 65, and the other end of the second connecting rod 65 is connected to one end of the moving rod 66, and the other end of the moving rod 66 is fixed to one side of the moving sleeve 63.

[0064] Specifically, in actual use, the inner cavity height of the movable sleeve 63 matches the thickness of a single tea bag, that is, only one tea bag can be stored inside the movable sleeve 63. In the initial state, one tea bag is stored inside the movable sleeve 63.

[0065] When the tea bag needs to be put into the water cup, the controller controls the second electric push rod 64 to work, and the second electric push rod 64 can drive the moving rod 66 to move through the second connecting rod 65, thereby driving the moving sleeve 63 to slide between the U-shaped plate 61 and the bottom plate 59. At this time, the slide plate 62 slides inside the two second guide rails 60 to provide guidance and support. When the moving sleeve 63 moves out from above the U-shaped plate 61, that is, the U-shaped plate 61 no longer blocks the bottom end of the moving sleeve 63, the tea bag inside the moving sleeve 63 falls into the guide hopper 30 under the action of gravity, and the tea bag falls accurately into the water cup through the guide hopper 30.

[0066] like Figure 1-Figure 12 As shown, the flushing assembly includes a second pump body 50, two output pipes 51 and two nozzles 52. The two nozzles 52 are symmetrically arranged on both sides of the pressure plate 48. The second pump body 50 is installed above the water tank 20. The input end of the second pump body 50 is connected to the water tank 20. The output end of the second pump body 50 is connected to one end of the two output pipes 51 through a three-way pipe. The other end of each output pipe 51 passes through the brewing box 14 and is connected to a nozzle 52.

[0067] When it is necessary to flush the pressing plate 48, the controller controls the second pump body 50 to work, and the second pump body 50 transports the water inside the water tank 20 to the nozzle 52 through the output pipe 51, and sprays the water onto the pressing plate 48 through the nozzle 52, so as to flush the surface of the pressing plate 48, ensure the cleanliness of the surface of the pressing plate 48, and effectively prevent the residual tea on the pressing plate 48 from affecting the next brewing of the tea bag, thereby improving the taste of the brewed tea.

[0068] like Figure 1-Figure 12 As shown, a receiving box 17 fixed to the bottom of the brewing box 14 is provided below the brewing tank 15, and a plurality of through holes 16 are opened on one side of the brewing tank 15, each of the through holes 16 is connected to the receiving box 17, and a discharge pipe 18 is connected to the bottom of the receiving box 17, and the other end of the discharge pipe 18 extends out of the cabinet 11. The water after flushing the pressure plate 48 can fall into the inside of the brewing tank 15, and flow into the inside of the receiving box 17 through the through hole 16, and then the water in the receiving box 17 is guided out of the vending machine through the discharge pipe 18 to discharge the sewage.

[0069] like Figure 1-Figure 12 As shown, two inspection doors 12 for easy maintenance are symmetrically provided on both sides of the cabinet 11, and each inspection door 12 is detachably connected to the cabinet 11. By providing detachable inspection doors 12 on both sides of the cabinet 11, it is not only convenient to repair the interior of the cabinet 11, but also convenient to load and replenish tea bags, which is convenient to use.

[0070] The specific working process of the present invention is as follows: When a customer buys tea, he first places the disposable water cup inside the limit seat 67, and then the customer selects and determines the type of tea through the control switch on the operation panel 13. The control switch sends the information to the controller, and then the controller starts the motor 54 to work. The motor 54 can drive the third gear 55 to rotate. Since the third gear 55 and the fourth gear 56 are meshed with each other, when the third gear 55 rotates, the fourth gear 56 can be driven to rotate, so that the main shaft 57 can rotate, so that the multiple storage tanks 58 installed on the side wall of the main shaft 57 can rotate, so that the storage tanks 58 storing the required tea bags can be rotated. The tank 58 can rotate to the top of the avoidance hole 19, and the controller controls the second electric push rod 64 to work. The second electric push rod 64 can drive the moving rod 66 to move through the second connecting rod 65, thereby driving the moving sleeve 63 to slide between the U-shaped plate 61 and the bottom plate 59. At this time, the slide plate 62 slides inside the two second guide rails 60 to provide guidance and support. When the moving sleeve 63 moves out from above the U-shaped plate 61, that is, the U-shaped plate 61 no longer blocks the bottom end of the moving sleeve 63, the tea bag inside the moving sleeve 63 falls into the inside of the guide hopper 30 under the action of gravity, and the tea bag falls accurately into the inside of the water cup through the guide hopper 30.

[0071] Subsequently, the controller controls the first electric push rod 29 to work, and the first electric push rod 29 can drive the first rack 28 to slide above the brewing box 14 through the connecting plate 68. Since the first rack 28 and the first gear 27 are meshed with each other, when the first rack 28 moves, it can drive the first gear 27 to rotate, so that the rotation of the swing arm 25 can be realized through the central axis 26, so that the swing arm 25 can drive the guide hopper 30 and the water outlet pipe 24 to rotate, so that the positions of the guide hopper 30 and the water outlet pipe 24 are exchanged, and the controller controls the first pump body 21 to work, and the hot water inside the water tank 20 is transported to the water outlet pipe 24 through the hose 22 and the connecting pipe 23, and water is poured into the interior of the water cup through the water outlet pipe 24 to complete the brewing of the tea bag.

[0072] In this process, when the central shaft 26 rotates, the central shaft 26 can drive the cam 32 to rotate, so that the flange part of the cam 32 can abut against the surface of the rotating wheel 33. At this time, the first guide rod 35 moves inside the limit block 36 toward the side away from the rotating wheel 33, and the spring 37 is compressed. When the first guide rod 35 moves toward the side away from the rotating wheel 33, the first guide rod 35 can drive the second guide rod 39 to move through the first connecting rod 38, so that the second rack 40 can slide inside the first guide rail 41. Since the first guide rail 41 and the second gear 42 are meshed, when When the second rack 40 moves, it can drive the second gear 42 to rotate on the mounting plate 43. When the second gear 42 rotates, it can drive the turntable 44 to rotate synchronously. The turntable 44 can drive the insertion rod 45 to rotate. Since the insertion rod 45 is inserted into the inside of the strip groove 47, when the insertion rod 45 rotates, it can drive the swing frame 46 to swing, so that the pressure plate 48 at one end of the swing frame 46 can swing synchronously, so that the pressure plate 48 can rotate to the inside of the water cup, realizing the function of limiting and blocking the tea bag, which can effectively prolong the soaking time of the tea bag during the tea bag brewing process and improve the brewing effect of the tea bag.

[0073] After the water filling is completed, the controller starts the first electric push rod 29 to make the guide hopper 30 and the water outlet pipe 24 switch positions again to facilitate the next tea bag loading. At this time, the pressing plate 48 can be moved out from the inside of the water cup, and the customer can take the tea out from the inside of the brewing tank 15.

[0074] After the tea is taken out, the controller controls the second pump body 50 to work, and the second pump body 50 transports the water inside the water tank 20 to the nozzle 52 through the output pipe 51, and the water is sprayed onto the pressing plate 48 through the nozzle 52, so as to flush the surface of the pressing plate 48 and ensure the cleanliness of the surface of the pressing plate 48. It can effectively prevent the residual tea on the pressing plate 48 from affecting the brewing of the next tea bag, and can improve the taste of the brewed tea.

[0075] The beneficial effects of the present invention are specifically embodied in that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
