[0035] The present application embodiment provides an automatic liquid supply device 10, please refer to Figure 1-Figure 3 It includes a chassis 11, a tray 12, an ultraviolet disinfection lamp, an electric heating tube, a material transport mechanism 13, a driving mechanism 14, a feeding mechanism 15 and a central control console 16.

[0036] The chassis 11 includes an outer shell 111 and an inner shell 112 that are spaced apart, and an installation space is formed between the outer shell 111 and the inner shell 112. Two partition members 110 are arranged between the outer shell 111 and the inner shell 112 to divide the installation space into a first accommodating chamber 113 and a second accommodating chamber 114. An ultrasonic cleaning machine 115 is installed inside the first accommodating chamber 113, and clean water can be stored in the ultrasonic cleaning machine 115. The side wall of the chassis 11 corresponding to the second accommodating chamber 114 has a take-in and put-out port 116, and the take-in and put-out port 116 is installed with a shielding plate 117, which is pivotally connected to the side wall of the chassis 11; the upper wall of the chassis 11 has a feed port 118.

[0037] Since an ultrasonic cleaning machine 115 is installed inside the first accommodating chamber 113, and clean water can be stored in the ultrasonic cleaning machine 115, before filling the liquid into the container, the container can be placed in the ultrasonic cleaning machine 115 for cleaning, and after cleaning, the container can be placed in the groove 121 of the tray 12 for liquid filling. The access port 116 is installed with a shielding plate 117, and the shielding plate 117 is pivotally connected to the side wall of the chassis 11. When the container needs to be cleaned, the shielding plate 117 is opened and the container is placed in the ultrasonic cleaning machine 115; when the container does not need to be cleaned, the access port 116 can be blocked by the shielding plate 117. In addition, the ultrasonic cleaning machine 115 can also be taken out from the access port 116 to replace clean water.

[0038] In a possible embodiment, a detergent placement box 194 is installed in the second accommodating chamber 114, and the detergent placement box 194 has a detergent placement opening 195 at a position corresponding to the outer shell 111. Detergent can be placed in the detergent placement box 194, so that the detergent can be used for cleaning when cleaning the containing device.

[0039] Among them, a convex support member 119 is provided on the inner wall of the chassis 11, the tray 12 is arranged inside the chassis 11 and can be supported on the convex support member 119, and the tray 12 has multiple rows of grooves 121, and each row of grooves 121 has multiple grooves 121; the multiple rows of grooves 121 are arranged at intervals and arranged along the width direction of the chassis 11, and the grooves 121 are used to place liquid-containing devices.

[0040] The material transport mechanism 13 includes a material transport box 131 and multiple nozzles 132. Each nozzle 132 in the multiple nozzles 132 can correspond to each groove 121 in a row of grooves 121. Each nozzle 132 is connected to the material transport box 131. The nozzles 132 are installed with a flow switch. Each nozzle 132 is installed with an infrared sensor and a first non-contact liquid level sensor. A second non-contact liquid level sensor is installed at the groove 121. The infrared sensor is used to monitor whether there is a liquid-containing device at the groove 121. The first non-contact liquid level sensor and the second non-contact liquid level sensor are used to monitor the liquid level of the liquid-containing device.

[0041] The driving mechanism 14 is used to drive the material transport box 131 to move in the chassis 11 along the width direction of the chassis 11 , and the feeding mechanism 15 is used to supply liquid to the material transport box 131 .

[0042] The central console 16 is installed on the side wall of the chassis 11 corresponding to the second accommodating cavity 114. The central console 16 is provided with a controller, and the controller is signal-connected with the flow switch, the infrared sensor, the first non-contact liquid level sensor and the second non-contact liquid level sensor respectively.

[0043] Liquids such as beverages or water can be poured into the transport box 131 through the feeder 15. The grooves 121 of the tray 12 are used to place liquid-containing devices. Since the tray 12 has multiple rows of grooves 121, each row of grooves 121 has multiple grooves 121, and the multiple rows of grooves 121 are arranged at intervals and arranged along the width direction of the chassis 11, the transport box 131 is connected to the nozzles 132, and each nozzle 132 can correspond to each groove 121 in a row of grooves 121. The driving mechanism 14 drives the transport box 131 to move along the width direction of the chassis 11, and the nozzles 132 can pour liquid into the liquid-containing devices on the tray 12. Since each nozzle 132 is equipped with an infrared sensor, the infrared sensor is used to monitor whether there is a liquid-containing device at the groove 121. When the infrared sensor detects that there is a liquid-containing device at the groove 121, the signal is transmitted to the controller, and the controller controls the drive motor 141 to stop working. Since each nozzle 132 is equipped with a first non-contact liquid level sensor, and each groove 121 is equipped with a second non-contact liquid level sensor, the first non-contact liquid level sensor and the second non-contact liquid level sensor located above and below the liquid holding device work together to detect the liquid level of the liquid holding device and transmit the liquid level signal to the controller. The controller controls the flow switch of the nozzle 132 to pour liquid into the liquid holding device according to the liquid level of the liquid holding device, so that a certain amount of liquid can be poured more accurately and conveniently, and the liquid is not easy to spill. When the liquid holding device is filled with liquid, the tray 12 can be taken out, and the tray 12 can be placed on the convex support 119 after use or when liquid needs to be added again. Exemplarily, handles 120 are installed at opposite ends of the tray 12 to facilitate the removal and placement of the tray 12.

[0044] Reference Figure 6 The driving mechanism 14 includes a driving motor 141, a gear 142 and a guide rail 143 that can mesh with the gear 142. The guide rails 143 are installed on opposite sides of the material transport box 131. The guide rails 143 have teeth that match the gear 142. The controller is connected to the driving motor 141 by signal.

[0045] The guide rail 143 extends along the width direction of the chassis 11, and a slide groove (not shown in the figure) is opened inside the chassis 11. The guide rail 143 has a first end and a second end along its width direction. The first end is connected to the outer wall of the material transport box 131, and the second end is slidably matched with the slide groove; the drive motor 141 is installed on the chassis 11, and the power output end of the drive motor 141 is coaxially connected to the gear 142, and the gear 142 is meshed with the guide rail 143.

[0046] The driving motor 141 can drive the gear 142 to rotate, and the rotation of the gear 142 can drive the guide rail 143 to move linearly. The movement of the guide rail 143 can drive the material transport box 131 to move along the width direction of the chassis 11. The chassis 11 has a slide groove inside, and the second end of the guide rail 143 can slidably cooperate with the slide groove, so that the slide groove can form a certain support for the material transport box 131 and can ensure that the guide rail 143 moves linearly smoothly. Optionally, both ends of the extension direction of the guide rail 143 are installed with travel switches, and the travel switches are connected to the controller signal. When the gear 142 contacts the travel switch, the travel switch transmits a signal to the controller, and the controller controls the driving motor 141 to reverse.

[0047] For example, a through hole 122 is formed at the groove 121, and the through hole 122 penetrates the tray 12 along the thickness direction of the tray 12 (see Figure 3-Figure 5 ).

[0048] Since the through hole 122 is opened in the groove 121 of the tray 12 , if there is liquid on the outer wall of the contained device, it can flow along the through hole 122 into the inside of the chassis 11 .

[0049] In a possible implementation, the automatic liquid supply device 10 also includes a baffle 17, which is installed inside the chassis 11 to divide the inside of the chassis 11 into a sewage treatment area and a filling area; the baffle 17 is arranged below the convex support member 119; the baffle 17 is funnel-shaped, and a liquid outlet 171 is provided at the bottom of the funnel-shaped baffle 17, and the liquid outlet 171 connects the sewage treatment area and the filling area.

[0050] Since the baffle 17 is funnel-shaped and a liquid outlet 171 is provided at the bottom of the baffle 17 , the liquid flowing down from the through hole 122 of each groove 121 can drip onto the baffle 17 , and the funnel-shaped baffle 17 collects the liquid to the liquid outlet 171 and then flows from the liquid outlet 171 to the sewage treatment area.

[0051] Furthermore, the automatic liquid supply device 10 is also provided with an ultraviolet disinfection lamp and an electric heating tube. The ultraviolet disinfection lamp is installed in the inner shell 112 and is located above the convex support 119; the electric heating tube is installed in the inner shell 112, and the electric heating tube is installed above and below the tray 12.

[0052] The chassis 11 has an electric heating tube inside, and the tray 12 is installed with electric heating tubes above and below. The electric heating tube below the tray 12 can dry the liquid flowing from the through hole 122, and the electric heating tube above the tray 12 can be baked before and after the liquid is poured. The chassis 11 has an ultraviolet disinfection lamp inside, which can perform ultraviolet disinfection, making it more hygienic to use.

[0053] The feeding mechanism 15 includes an adapter 151 and a feeding assembly. The feeding assembly includes an inlet pipe 152, a soft material layer 153 wrapped around the outer wall of the inlet pipe 152, and a valve 154 arranged on the inlet pipe 152. The inlet pipe 152 is movably placed at the feed port 118; the adapter 151 is installed inside the chassis 11, one end of the adapter 151 is connected to the material transport box 131 through a hose, and the other end of the adapter 151 is connected to the feed port 118.

[0054] Liquids such as beverages or water can be poured into the transport box 131 through the feeding mechanism 15. When the transport box 131 needs to be filled with liquid, the feeding assembly is taken out from the feeding port 118, and one end of the water inlet pipe 152 is inserted into the bottle containing the liquid from the bottle mouth. Since the outer wall of the water inlet pipe 152 has a soft material layer 153, the soft material layer 153 can well seal the bottle mouth to prevent the liquid from leaking out when entering the water inlet pipe 152. The water inlet pipe 152 has a valve 154, and the flow of liquid in the bottle into the water inlet pipe 152 can be controlled by opening or closing the valve 154. When the valve 154 is in a closed state, the other end of the water inlet pipe 152 inserted into the bottle can be placed at the feeding port 118, and then the valve 154 is opened, so that the liquid in the bottle flows to the feeding port 118 through the water inlet pipe 152. Since one end of the adapter 151 is connected to the material transport box 131 through a hose, and the other end of the adapter 151 is connected to the feed port 118, liquid can flow from the feed port 118 through the adapter 151 into the material transport box 131, so that sufficient liquid is stored in the material transport box 131.

[0055] Optionally, the thickness of the soft material layer 153 at both ends of the water inlet pipe 152 is smaller than the thickness in the middle of the water inlet pipe 152. This makes it easier to insert the water inlet pipe 152 into the bottle, and the soft material layer 153 in the middle of the water inlet pipe 152 can seal the bottle mouth. Exemplarily, the material of the soft material layer 153 is rubber.

[0056] Furthermore, the feeding mechanism 15 also includes a feeding support plate 18, which is tilted close to the feeding port 118, and the lateral distance between the end of the feeding support plate 18 close to the chassis 11 and the edge of the feeding port 118 is L1, and the lateral distance between the end of the feeding support plate 18 away from the chassis 11 and the edge of the feeding port 118 is L2, and L1 is smaller than L2.

[0057] When the liquid in the bottle is poured into the material transport box 131, the feed support plate 18 can provide a certain support to the bottle, reducing the chance of liquid spilling. Exemplarily, the surface of the feed support plate 18 has a rubber layer, which can increase the friction with the bottle and provide better support stability. Optionally, the surface of the rubber layer has anti-slip bumps, which can provide more stable support to the bottle.

[0058] Furthermore, the inner shell 112 of the chassis 11 is equipped with a rotating shaft 191 and a clamping piece 192, which are arranged on opposite sides of the top of the chassis 11. The clamping piece 192 has a bayonet 1921. The rotating shaft 191 is rotatably supported on the inner shell 112. A soft curling cover 193 is wound on the rotating shaft 191. The end of the soft curling cover 193 has a hook 1931, and the hook 1931 can be fixed to the bayonet 1921.

[0059] When the top of the chassis 11 needs to be shielded, the hook 1931 is hooked on the bayonet 1921. When the top of the chassis 11 needs to be opened, the hook 1931 is separated from the bayonet 1921, and the soft curling cover 193 is rolled on the rotating shaft 191.

[0060] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
