A water bucket fixing mechanism and a water vending machine

Abstract

This utility model discloses a water bucket fixing mechanism and a water vending machine. The water bucket fixing mechanism includes a water dispensing chamber with an outer ring flange seat centrally fixed to its inner bottom and an inner ring flange seat located axially distributed around the outer ring flange seat, forming a water bucket opening insertion groove between the two flange seats. It also includes a locking plate that is driven to move horizontally, and the outer ring flange seat has a slot for the locking plate to move. This utility model has a simple structure and can fix the water bucket opening, which is inverted and inserted into the water bucket opening insertion groove, to ensure that the water bucket will not detach from the groove due to water flow impact during rinsing.

Description

Technical Field

[0001] This utility model relates to a water vending machine, specifically a water bucket fixing mechanism and a water vending machine. Background Technology

[0002] Before dispensing water, the water vending machine needs to rinse the water bucket. During operation, the bucket is placed upside down on the rinsing plate at the bottom of the water tank and secured with a fixing mechanism. Upon receiving this signal, the gravity sensor activates the rinsing nozzles to rinse the inside of the container. This ensures the container is clean before dispensing water, improving user safety. The rinsing process uses purified water first, followed by ozone water. The wastewater flows into a wastewater tank. By using a gravity sensor to monitor the container's position, the rinsing process is prevented from being activated if the container is not placed correctly, thus avoiding any impact on the rinsing effect.

[0003] Referring to Chinese Patent No. CN216705369U, published on June 10, 2022, a device for cleaning the water tank of a water vending machine is disclosed. The device includes: a water vending machine with a cleaning chamber; a mounting cover, the bottom of which is fixedly installed inside the cleaning chamber, and a filter screen fixedly installed on the outer surface of the mounting cover; and a booster pump, the surface of which is installed inside the mounting cover. This device for cleaning the water tank of a water vending machine uses a booster pump to draw water stored inside the cleaning chamber. A pulse solenoid valve controls a cleaning nozzle to spray and rinse the inside of the water tank through a connecting pipe. After rinsing, it facilitates the washing and cleaning of impurities on the inner surface of the water tank, thereby enhancing the water vending machine's cleaning function. The cleaned water can automatically flow downwards and be reused after filtration, making it more energy-efficient and environmentally friendly.

[0004] In the prior art, including the aforementioned patent, during rinsing, the upward-spraying liquid impacts the bottom of the inner side of the bucket, so the bucket needs to be locked to prevent it from being pushed out by the sprayed liquid. How to solve this problem is something we look forward to. Utility Model Content

[0005] The purpose of this invention is to provide a water bucket fixing mechanism and a water vending machine to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water bucket fixing mechanism, including a water pumping chamber, an outer ring flange seat and an inner ring flange seat located at the center of the bottom of the chamber, and a water bucket opening insertion groove is formed between the two flange seats.

[0007] It also includes a locking plate that is driven to move horizontally, and the outer flange seat has a slot for the locking plate to move.

[0016] A water vending machine includes the water bucket fixing mechanism described in the above solution.

[0017] In the above technical solution, the water bucket fixing mechanism and water vending machine provided by this utility model have the following beneficial effects: by driving the locking plate to move, the outer tube wall of the water bucket mouth inserted into the water bucket mouth insertion groove is brought into contact, so that the inner tube wall of the water bucket mouth is attached to the inner ring flange seat (3), thereby realizing the locking and fixing of the water bucket inverted, so as to facilitate the subsequent rinsing operation.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a water bucket fixing mechanism and a water vending machine, wherein the water dispensing chamber 1 is installed on the water vending machine.

[0027] Furthermore, an outer ring flange seat 2, which is fixedly installed in the center of the bottom inside the water tank 1 by bolts, is integrally cast with the inner ring flange seat 3. The inner ring flange seat 3 is located in the center of the outer ring flange seat 2, and a water bucket inlet insertion groove 4 is formed between the outer ring flange seat 2 and the inner ring flange seat 3. The mouth of the water bucket is inserted into the water bucket inlet insertion groove 4.

[0028] Secondly, a telescopic motor 6 is fixedly installed on the outer wall of the water tank 1, and a locking plate 5 is fixedly installed on the output end of the telescopic motor 6. When the mouth of the water bucket is inserted into the water bucket mouth insertion slot 4, the gravity sensor senses that the container is triggered. At this time, the telescopic motor 6 drives the locking plate 5 to extend from the slot 21 on the outer flange seat 2 into the water bucket mouth insertion slot 4, so that the arc-shaped surface 51 of the locking plate 5 abuts against the outer wall of the water bucket mouth for fixation.

[0029] Furthermore, the bottom of the water tank 1 is equipped with cleaning water nozzles 8 centrally located within the inner flange seat 3, and a predetermined distance is maintained between the cleaning water nozzles 8 and the inner flange seat 3. This means that when the cleaning water nozzles 8 are activated, they spray cleaning liquid to rinse the inside of the water tank. The rinsing water is first rinsed with ozone water, and then rinsed with purified water at the end. The wastewater after rinsing flows into the wastewater tank.

[0030] It should be noted that the aforementioned inner cover 7 is fixedly installed to the bottom of the inner side of the water tank 1 by bolts, and the outer flange seat 2 extends out from the through hole opened on the inner cover 7, and the port section is at the same level as the upper surface of the inner cover 7. After rinsing the water bucket, the water bucket is removed and placed on the inner cover 7. Then, the drinking water filling nozzle fixedly installed on the top of the inner side of the water tank 1 is used to fill the water for drinking (in this embodiment, rinsing the water bucket lasts for 2 to 3 minutes. After the predetermined time is reached, the telescopic motor 6 drives the locking plate 5 to move back to its original position, that is, to release the locking of the water bucket opening).

[0031] Among them, the outer ring flange seat 2 and the inner ring flange seat 3 are made of stainless steel.

[0032] Furthermore, combining Figure 4 As shown, cylindrical members 52 are symmetrically rotated on the arc-shaped surface 51, and an arc-shaped elastic metal plate 53 is welded between the two cylindrical members 52. The arc-shaped elastic metal plate 53 and the inner arc surface of the arc-shaped surface 51 are adjacent to each other. When the telescopic motor 6 drives the locking plate 5 to extend from the slot 21 on the outer flange seat 2 into the water bucket opening insertion slot 4, the outer arc apex of the arc-shaped elastic metal plate 53 first abuts against the outer wall of the water bucket opening. Then, as the arc-shaped surface 51 approaches the outer wall of the water bucket opening, the arc-shaped surface 51 deforms. Finally, the cylindrical member 52 abuts against the outer wall of the water bucket opening, thereby locking the water bucket.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
