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 number CN 202320828476.9, entitled "A Water Dispenser with Anti-Splash Function," uses the cooperation of a first clamp and a second clamp to fix the cup to the body, and uses a motor to drive the body to lift and lower to reduce the distance between the cup and the water outlet, thereby achieving the anti-splash effect of the water dispenser.

[0004] However, the above solution requires an additional motor to drive the cup to lift and lower, 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 problems is as follows: a water dispenser anti-splash structure, including a body and a water cup, the front side of the body has a water receiving cavity for accommodating the water cup, the top side of the water receiving cavity has a water outlet plate, the water outlet plate has a water outlet, characterized in that: it also includes a locking component for locking and unlocking the relative position of the water outlet plate and the water cup, in the locked state, the water cup is covered at the bottom of the water outlet plate, and a closed area connected to the water outlet is formed between the water cup and the water outlet plate.

[0007] To facilitate locking and unlocking of the water cup, the device body has a cavity located above the water outlet plate. The water outlet plate has a notch connecting the water receiving cavity and the cavity. The edge of the top of the water cup has a limiting block corresponding to the notch. The side of the limiting block has a limiting protrusion. The limiting protrusion can pass through the corresponding notch with the limiting block and is limited to above the water outlet plate after rotating with the water cup. The limiting block and the notch together form the locking assembly.

[0008] To ensure stability after the water cup is locked, there are at least two notches, which are arranged circumferentially around the outer periphery of the water outlet. There are at least two limiting blocks, which correspond one-to-one with the notches.

[0009] To achieve a stable positioning of the water cup, a clamping component is also included for holding the water cup in the locked state.

[0010] To achieve the clamping of the water cup, the clamping assembly is disposed within the cavity and includes [missing information].

[0011] At least two grippers corresponding to the limiting block, each gripper located outside the corresponding limiting block; and

[0012] The driving component is used to drive the grippers to move closer together to clamp on the outside of the limiting block and to drive the grippers to move away from each other to release the clamping of the limiting block.

[0013] To drive the grippers, there are two notches, two limit blocks, and two grippers. The driving component is a gripper cylinder with two output ends, which are respectively connected to the two grippers.

[0014] To enhance safety, a first sensor is also included to monitor whether the cup has been rotated into the locked position.

[0015] In order to monitor whether the water cup has rotated to the locked position, the first sensor is a limit switch, which is installed on the top of the water outlet plate and corresponds to the limit protrusion. In the locked state, the limit protrusion triggers the contact of the corresponding limit switch.

[0016] To prevent overflow, a second sensor is also included to monitor whether the amount of water in the cup has reached a set value.

[0017] In order to monitor whether the water level in the cup has reached the set value, the second sensor is an audio sensor, which is installed at the bottom of the water outlet plate and arranged close to the water outlet.

[0018] Compared with the prior art, the advantages of this utility model are as follows: by setting a locking component to lock and unlock the relative position of the water outlet plate and the water cup, in the locked state, the water cup is placed at the bottom of the water outlet plate and forms a closed area connected to the water outlet between the water outlet plate and the water outlet plate. Due to the formation of the closed area, the splashing area is sealed inside the water cup, thus preventing splashing. There is no need to set an additional lifting mechanism, and the structure is simple and low in cost. Attached Figure Description

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.

[0026] like Figures 1 to 5 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 cup 2, a clamping assembly 3, a first sensor 4, and a second sensor 5.

[0027] The front side of the body 1 has a water receiving cavity 11 for accommodating the water cup 2; the top side of the water receiving cavity 11 has a water outlet plate 12, on which a water outlet 121 is provided, and a downwardly extending water nozzle 1211 is connected to the water outlet 121; the body 1 is provided with a water supply device (not shown in the figure) for supplying water to the water outlet 121; the body 1 has a cavity 13 located above the water outlet plate 12, and the water outlet plate 12 has two notches 122 arranged circumferentially around the water outlet 121, which connect the water receiving cavity 11 and the cavity 13.

[0028] Two circumferentially spaced limiting blocks 21 are located at the top edge of the water cup 2. Each limiting block 21 corresponds to a notch 122. Each limiting block 21 has a limiting protrusion 211 protruding on the same circumferential side. The limiting protrusion 211 can pass through the corresponding notch 122 with the limiting block 21 and is positioned above the water outlet plate 12 after the water cup 2 rotates. The limiting blocks 21 and notches 122 together form a locking assembly for locking and unlocking the relative positions of the water outlet plate 12 and the water cup 2. In the locked state, the limiting protrusion 211 of the limiting block 21 is positioned above the water outlet plate 12, the water cup 2 covers the bottom of the water outlet plate 12, and a closed area 20 communicating with the water outlet 121 is formed between the water cup 2 and the water outlet plate 12.

[0029] The clamping assembly 3 is used to clamp the water cup 2 in the locked state. In this embodiment, the clamping assembly 3 is disposed in the cavity 13 and includes a gripper 31 and a driving member 32. Specifically, there are two grippers 31, which correspond one-to-one with the aforementioned limiting blocks 21, and each gripper 31 is located outside the corresponding limiting block 21; the driving member 32 is a gripper cylinder, which has two output ends, respectively connected to the two grippers 31, for driving the two grippers 31 to move closer together to clamp on the outside of the limiting block 21 and driving the two grippers 31 to move away from each other to release the clamping of the limiting block 21.

[0030] The first sensor 4 is used to monitor whether the water cup 2 has rotated to the locked position. In this embodiment, the first sensor 4 is a limit switch, which is installed on the top of the water outlet plate 12 and corresponds to the limit protrusion 211. In the locked state, the limit protrusion 211 triggers the contact of the corresponding limit switch.

[0031] The second sensor 5 is used to monitor whether the water level in the cup 2 has reached a set value. In this embodiment, the second sensor 5 is an audio sensor, which is installed at the bottom of the water outlet plate 12 and arranged near the water outlet 121.

[0032] The working principle of this embodiment is as follows: When water needs to be collected, hold the water cup 2 and insert it into the water receiving chamber 11. Then, align the limiting block 21 of the water cup 2 with the notch 122 of the water outlet plate 12 and insert it upwards to the limit position. Next, rotate the water cup 2 counterclockwise until the limiting protrusion 211 of each limiting block 21 triggers the contact point of the corresponding first sensor 4. At this time, if... Figure 4 and Figure 5As shown, the water cup 2 is in a locked state. The limiting protrusion 211 of the limiting block 21 is positioned above the water outlet plate 12. The water cup 2 covers the bottom of the water outlet plate 12, and a closed area 20 communicating with the water outlet 121 is formed between the water cup 2 and the water outlet plate 12. At the same time, after receiving the signal sent by the first sensor 4, the controller controls the drive component 32 to drive the two grippers 31 to move closer together to clamp the outside of the limiting block 21, so as to achieve a stable positioning of the water cup 2. Then, the water outlet button (not shown in the figure) on the machine body 1 is pressed, and the water outlet 1211 supplies water to the water cup 2. Due to the formation of the closed area 20, the splashing area is contained in the water cup. Inside the cup 2, splash prevention is achieved. In addition, during the water dispensing process, as the water level in the cup 2 gradually rises, the length of the air column above the water surface becomes shorter and shorter, the frequency of the air column vibration becomes faster and the pitch becomes higher and higher. When the second sensor 5 detects that the pitch is higher than the set value, it means that the water volume in the cup 2 has reached the set value. After receiving the signal sent by the second sensor 5, the controller controls the spout 1211 to stop dispensing water to prevent overflow. At the same time, the controller controls the drive unit 32 to drive the two grippers 31 to move away from each other and release the gripping of the limit block 21. Finally, the cup 2 can be rotated clockwise to the limit position and then taken out downwards to complete the water filling process.

[0033] During this period, if the limit protrusion 211 does not trigger the contact point of the corresponding first sensor 4, it means that the water cup 2 has not rotated to the locked state. At this time, the drive component 32 will not start, and the water outlet 1211 will not dispense water when the water outlet button is pressed, thus ensuring safety.
