Description

Technical Field

[0001] This utility model relates to the field of direct drinking water station technology, and more specifically, to a direct drinking water station water outlet device. Background Technology

[0002] Direct drinking water stations, as modern urban public drinking water facilities, are widely used in parks, schools, transportation hubs, and other places. They purify raw water through multi-stage filtration systems, providing users with safe drinking water. However, existing direct drinking water stations still have hygiene and safety hazards in actual use. Specifically, this is reflected in the water supply pipeline between the filtration structure and the outlet. As the final link in the purified water output, this section of pipeline, due to its enclosed structure and long-term humid environment, is prone to forming residual water retention areas. When the equipment is used less frequently in the community, the stagnant water has prolonged contact time with air. Coupled with changes in pipe wall temperature, this provides conditions for bacterial growth, posing a potential threat to the health of subsequent users. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a direct drinking water station water outlet device to solve the aforementioned problems.

[0004] This utility model is implemented as follows:

[0005] A direct drinking water station dispensing device includes a direct drinking water station body, which has a controller for controlling its operation inside, and a water receiving cavity is provided on its front side. A self-cleaning water nozzle is provided on the top wall of the water receiving cavity. The self-cleaning water nozzle includes a water outlet valve core and a housing. The housing is fixedly installed on the top wall of the water receiving cavity. The water outlet valve core is located inside the housing and is connected to the internal pipeline of the direct drinking water station body. A solenoid valve is connected to the bottom of the housing and is communicatively connected to the controller.

[0006] In an embodiment of this utility model, the water outlet valve core includes a pipe connection part, an inner water outlet pipe is provided at the bottom center of the pipe connection part, an inlet pipe is provided on the side of the pipe connection part near the top, the inlet pipe is connected to the inner water outlet pipe, a wastewater outlet is provided on the side of the pipe connection part away from the inlet pipe, a return channel is opened at the bottom of the pipe connection part near the outer side of the inner water outlet pipe, the return channel is connected to the wastewater outlet, the inlet pipe is connected to the water outlet pipe inside the main body of the drinking water station, and the wastewater outlet is connected to the internal wastewater return pipe.

[0007] In an embodiment of this utility model, an outwardly extending flange is provided at the top edge of the outer shell. The outer shell extends from the interior of the drinking water station body into the water receiving cavity. The bottom of the flange is fixed to the shell of the drinking water station body. The water outlet valve core is coaxially disposed inside the outer shell. The bottom of the pipe connection part is sealed together with the top of the flange. The opening of the return channel is located inside the outer shell.

[0008] In an embodiment of this utility model, the bottom of the outer shell is an opening, a mating ring is provided at the opening, and the bottom of the mating ring is provided with an internal thread structure.

[0009] In an embodiment of this utility model, the top of the solenoid valve is provided with an external thread structure, and the solenoid valve thread is provided on the mating ring.

[0012] The beneficial effects of this utility model are as follows: It achieves automatic rinsing through a self-cleaning water nozzle. When the user is ready to collect water, the controller first closes the solenoid valve. Purified water enters the inner outlet pipe from the inlet, spreads upwards along the bottom of the outer casing, rinses the inner cavity, and then flows into the wastewater return pipe through the return channel to complete self-cleaning. After rinsing, the solenoid valve opens, and purified water flows out normally for the user to collect. The self-cleaning time is set by the controller and is intelligently triggered according to the usage interval, ensuring that the outlet is clean after each long period of non-use. Its beneficial effects include: the gap design between the inner outlet pipe and the outer casing achieves full-coverage rinsing, effectively removing residual water from the pipes and reducing bacterial growth; automatic triggering of self-cleaning based on usage frequency avoids water waste caused by frequent rinsing; and the rinsing water is recycled to the wastewater pipe, reducing resource waste.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] like Figure 1-3 As shown, this utility model provides a direct drinking water station water outlet device, including a direct drinking water station body 10, which has a controller 11 for controlling operation inside, and a water receiving cavity 12 is provided on its front side. A self-cleaning water nozzle 20 is provided on the top wall of the water receiving cavity 12. The self-cleaning water nozzle 20 includes a water outlet valve core 21 and a housing 22. The housing 22 is fixedly installed on the top wall of the water receiving cavity 12, and the water outlet valve core 21 is located inside the housing 22. The water outlet valve core 21 is connected to the internal pipeline of the direct drinking water station body 10. A solenoid valve 30 is connected to the bottom of the housing 22. The solenoid valve 30 is communicatively connected to the controller 11. By controlling the opening and closing of the solenoid valve 30, different flow directions of purified water can be realized. That is, when the solenoid valve 30 is closed, it performs self-cleaning, discharges residual water in the water supply pipeline between the filter structure and the water outlet, and rinses the self-cleaning water nozzle 20 once, reducing the potential problem of bacterial growth and avoiding health threats to users.

[0021] like Figure 3 As shown, the water outlet valve core 21 includes a pipe connection part 2102. An inner water outlet pipe 2101 is provided at the bottom center of the pipe connection part 2102. An inlet pipe 21021 is provided on the side of the pipe connection part 2102 near the top. The inlet pipe 21021 is connected to the inner water outlet pipe 2101. A wastewater outlet 21022 is provided on the side of the pipe connection part 2102 away from the inlet pipe 21021. A return flow channel 21023 is opened at the bottom of the pipe connection part 2102 near the outer side of the inner water outlet pipe 2101. The return flow channel 21023 is connected to the wastewater outlet 21022. The inlet pipe 21021 is connected to the water outlet pipe inside the main body 10 of the drinking water station. The wastewater outlet 21022 is connected to the wastewater return pipe inside.

[0022] Furthermore, an outwardly extending flange 2201 is provided at the top edge of the outer casing 22. The outer casing 22 penetrates from the interior of the drinking water station body 10 into the water receiving cavity 12. The bottom of the flange 2201 is fixed to the casing of the drinking water station body 10. The water outlet valve core 21 is coaxially disposed inside the outer casing 22. The bottom of the pipe connection part 2102 is sealed together with the top of the flange 2201. The opening of the return channel 21023 is located inside the outer casing 22.

[0023] Furthermore, the bottom of the outer casing 22 is an opening, and a mating ring 23 is provided at the opening. The bottom of the mating ring 23 is provided with an internal thread structure.

[0024] Furthermore, the top of the solenoid valve 30 is provided with an external thread structure, and the thread of the solenoid valve 30 is provided on the mating ring 23.

[0025] Furthermore, a recess is formed at the internal thread structure of the mating ring 23, and a sealing ring 24 is provided on the recess. The top of the solenoid valve 30 abuts against the sealing ring 24.

[0026] The gap between the outer shell 22 and the inner water outlet pipe 2101 forms a space for rinsing and drainage. When the solenoid valve 30 is closed, water spreads upward from the bottom of the outer shell 22. When it spreads to the top return channel 21023, it enters the wastewater pipe and flows into the wastewater return pipe inside the main body 10 of the drinking water station. After rinsing is completed, the solenoid valve 30 is opened, and the subsequent purified water can flow normally into the user's container.

[0027] When it needs to be explained, the self-cleaning time (i.e., the closing time of the solenoid valve 30) is set in the controller 11. In the embodiment of this application, the single self-cleaning opening time is 10s.

[0028] In one embodiment, the self-cleaning strategy of the main body 10 of this direct drinking water station is as follows: if it has not been used for more than 30 minutes, the self-cleaning operation is performed when the user takes water; if it has been less than 30 minutes since the last user took water, the solenoid valve 30 is opened to directly take water.

[0029] In this embodiment, the distance between the bottom end of the inner water outlet pipe 2101 and the docking ring 23 is 1cm, and the distance between it and the inner sidewall of the outer shell 22 is 0.5cm, ensuring that the gap between the inner water outlet pipe 2101 and the outer shell 22 is sufficient for rinsing.

[0030] Specifically, the working principle of this direct drinking water station water outlet device is as follows: When the user swipes their card to prepare for water dispensing, a self-cleaning operation is first performed. That is, the controller 11 controls the solenoid valve 30 to be in the closed state. At this time, purified water enters the inner outlet pipe 2101 from the inlet pipe 21021, spreads from the bottom to the top of the outer shell 22, and finally flows out from the return channel 21023. After a certain period of time, the solenoid valve 30 is opened first, and after a 1-second interval, the water pump of the direct drinking water station body 10 is turned off. During this 1-second time, the pipe of the solenoid valve 30 is flushed. Then, it waits for the user's preparation. Through the above structure, the problem of bacteria easily growing in the water supply pipe between the filtration structure and the outlet in the direct drinking water station, which affects the user's health, is solved.

[0031] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
