Description

Technical Field

[0001] This utility model relates to the field of drinking water equipment technology, specifically to a water dispenser anti-splash structure. Background Technology

[0002] Traditional water dispensers require placing the cup on the water container and pressing the dispensing button. This method is prone to splashing, especially when the cup is short. The water flow impacts the bottom of the cup, causing the water droplets to bounce out of the cup.

[0003] To address this, Chinese patent application CN202322265727.X, entitled "Intelligent Water Receiving Box and Drinking Water Purification Device," provides an intelligent water receiving box and drinking water purification device, including: a sensor, a lifting motor, a controller, and a water receiving box body; the controller is also connected to an external faucet; the sensor is installed above the water receiving box body; the sensor is used to scan a preset area above the water receiving box body to obtain scan data; the controller is used to determine the height of the water storage device if a water storage device is detected above the water receiving box body through the sensor; the controller is used to determine the target position of the water receiving box body based on the height of the water storage device; and controls the lifting motor to operate, so as to drive the water receiving box body to rise and fall to the target position; the controller is also used to control the faucet to operate the water dispensing operation when the water receiving box body is detected to reach the target position. This intelligent water receiving box, by detecting the height of the water storage device above the water receiving box body, raises and lowers the water receiving box body to a suitable position to prevent safety hazards caused by splashing water.

[0004] However, the above solution requires the sensor to first determine the height of the water cup and then determine the rising height of the water receiving box, which is complex and costly. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a water dispenser anti-splash structure that is simple in structure and low in cost, in light of the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows: a water dispenser anti-splash structure, including a body, a water receiving cavity on the front side of the body, a water outlet at the top of the water receiving cavity, and a water receiving box for holding a water cup at the bottom of the water receiving cavity, characterized in that: it also includes...

[0007] A lifting mechanism is used to drive the water receiving box to rise and fall.

[0008] A sensor is used to monitor whether the edge of the top of the water cup reaches a set height; and

[0009] The controller is used to receive the signals collected by the sensor and control the opening and closing of the lifting mechanism.

[0010] To drive the water receiving box to rise and fall, the lifting mechanism includes:

[0011] The lifting plate is connected to the water receiving box via a connecting rod;

[0012] A lead screw, extending vertically and threadedly connected to the lifting plate; and

[0013] A driving component is used to drive the lead screw to rotate around its own axis.

[0014] To ensure the stable lifting of the lifting plate, the lifting mechanism also includes a guide rail, which is fixed relative to the machine body and extends in a vertical direction. The lifting plate has a guide notch that cooperates with the guide rail.

[0015] To improve stability, there are two guide rails, which are symmetrically arranged on the left and right sides of the lifting plate.

[0016] To ensure the stable rotation of the lead screw, the lifting mechanism also includes a bracket, which is fixed relative to the machine body. Each lead screw has two brackets, and the two ends of the lead screw are rotatably connected to the two brackets respectively.

[0017] To ensure that the lifting plate is subjected to uniform force, there are at least two lead screws, which are arranged at intervals in the left and right direction. There are at least two driving components, which correspond one-to-one with the lead screws.

[0018] To facilitate the installation of the drive component, the lifting mechanism also includes a fixing plate, which is fixed relative to the machine body. The drive component is a motor, which is mounted on the fixing plate, and its power output end is coaxially connected to the lead screw.

[0019] To facilitate the installation of the lifting mechanism, the machine body has an internal cavity, and the lifting mechanism is located in the internal cavity. The connecting rod extends upward from the top surface of the lifting plate to the water receiving cavity and connects to the bottom surface of the water receiving box.

[0020] To ensure the stable raising and lowering of the water receiving tray, the number of connecting rods is at least two, and they are arranged at intervals in the left-right direction.

[0021] To monitor whether the edge of the top of the water cup has reached the set height, the sensor is a photoelectric switch, which is installed on the side of the water receiving cavity and directly opposite the water outlet of the spout.

[0022] Compared with the prior art, the advantages of this utility model are: the water receiving box is raised and lowered by a lifting mechanism, and the edge of the top of the water cup is monitored by a sensor to see if it reaches the set height. The controller can shut off the lifting mechanism according to the signal collected by the sensor, so as to realize the anti-splash function of cups of different sizes. The structure is simple and the cost is low. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0028] like Figures 1 to 3 The image shows a preferred embodiment of the anti-splash structure for a water dispenser according to this utility model. The anti-splash structure includes a body 1, a water outlet 2, a water receiving box 3, a lifting mechanism 4, and a sensor 5.

[0029] The fuselage 1 has an inner cavity 11 inside; the front of the fuselage 1 has a water receiving cavity 12.

[0030] There are two water outlets 2, which are arranged at intervals on the top of the water receiving cavity 12 in the left-right direction.

[0031] The water receiving box 3 is movable up and down at the bottom of the water receiving cavity 12, and is used to hold the water cup 10.

[0032] The lifting mechanism 4 is located inside the inner cavity 11 and includes a guide rail 41, a lifting plate 42, a bracket 43, a lead screw 44, a fixing plate 45, and a driving component 46.

[0033] Specifically, there are two guide rails 41, which are vertically arranged on the left and right walls inside the inner cavity 11, respectively.

[0034] The lifting plate 42 is horizontally arranged in the inner cavity 11. The left and right sides of the lifting plate 42 are respectively provided with guide notches 421 that cooperate with the guide rail 41. The top of the lifting plate 42 is provided with two connecting rods 422 arranged at intervals in the left and right direction. Each connecting rod 422 extends upward from the top surface of the lifting plate 42 to the water receiving cavity 12 and connects to the bottom surface of the water receiving box 3.

[0035] There are four brackets 43, two of which are connected to the top and bottom of the guide rail 41 on the left side, and the other two are connected to the top and bottom of the guide rail 41 on the right side.

[0036] There are two lead screws 44, each extending vertically and corresponding to two supports 43. The two ends of the lead screw 44 are rotatably connected to the two corresponding supports 43, and the lead screw 44 is threadedly connected to the lifting plate 42.

[0037] The fixing plate 45 is installed inside the inner cavity 11;

[0038] There are two drive components 46, which correspond one-to-one with the lead screws 44. Each drive component 46 is a motor, which is mounted on the fixed plate 45. Its power output end is coaxially connected to the corresponding lead screw 44 to drive the lead screw 44 to rotate around its own axis.

[0039] Start the drive unit 46, which drives the lead screw 44 to rotate. Since the lifting plate 42 is threadedly connected to the lead screw 44, the lifting plate 42 drives the water receiving box 3 to rise and fall synchronously.

[0040] There are two sensors 5, each corresponding to one of the water outlets 2. Specifically, each sensor 5 is a photoelectric switch, installed on the side of the water receiving cavity 12 and facing the water outlet end of the corresponding water outlet 2, used to monitor whether the edge of the top of the water cup 10 has reached the set height.

[0041] In addition, the aforementioned water dispenser anti-splash structure also has a controller. The aforementioned sensor 5 and drive component 45 are both electrically connected to the controller so that the controller can receive the signals collected by the sensor 5 and control the opening and closing of the lifting mechanism 4.

[0042] The working principle of this embodiment is as follows: When water is needed, the user places the water cup 10 on the water collection box 3, and positions the open top of the water cup 10 directly opposite the water outlet 2 (e.g., Figure 2 (As shown), click the water dispensing button (not shown in the figure), the lifting mechanism 4 starts to drive the water receiving box 3 to rise until the sensor 5 detects the top edge of the water cup 10 (as shown in the figure). Figure 3As shown, a signal is sent, and the controller controls the lifting mechanism 4 to close so that the water receiving box 3 stops rising. At the same time, water comes out of the water outlet 2. Since the splashing area is controlled inside the water cup 10, it is ensured that the water flow will not splash out. After stopping the water receiving, there is a 2-second delay to ensure that the water in the water path is exhausted. The lifting mechanism 4 starts to drive the water receiving box 3 to descend, completing the water receiving.
