Description

Technical Field

[0001] This application relates to the field of water dispensers, and more particularly to a sterilization system for a water dispenser. Background Technology

[0002] With the increasing demand for healthy drinking water, water dispensers have become essential equipment in homes and public places, and their water quality safety is directly related to users' health. Currently, most water dispensers on the market use a bottled water supply model. Over long-term use, pipe contamination problems are becoming increasingly prominent, mainly concentrated in three key areas: water change operation, water dispensing process, and residual water treatment after shutdown. Even if drinking water meets sterility standards when leaving the factory, it still faces multiple risks during the internal transportation and storage process of the water dispenser, including air pollution, secondary pollution, and backflow contamination. Among these, bacterial adhesion to the pipe surface and secondary water contamination have become core issues affecting drinking water safety.

[0003] In existing technologies, the mainstream methods for pipeline disinfection include chlorine-containing effervescent tablet immersion, ozone fumigation, and pressure filtration. Immersion relies on chemical disinfectants, while ozone fumigation achieves sterilization through gas diffusion. Regarding contamination prevention, some top-mounted water dispensers use rubber seals at the bottle opening to isolate air, reducing the risk of contamination through physical sealing. For water sterilization, traditional solutions primarily focus on static disinfection within the water tank, achieving water purification through periodic irradiation.

[0004] However, existing technologies still have significant drawbacks. Chemical soaking methods are prone to leaving disinfectant residues, affecting the taste of drinking water and corroding equipment components. Ozone fumigation methods pose a risk of ozone leakage, and neither method can take effect immediately during water changes, leaving the problem of contamination when water pipes are exposed unresolved. Static sterilization in water tanks cannot avoid secondary contamination during water flow in the pipeline, especially when water stagnates, making it easy for bacterial films to form. Utility Model Content

[0005] In order to solve the problem of preventing external air from contaminating the surface of water pipes during water changes and to remove bacteria attached to the surface of water pipes, this application provides a sterilization system for a water dispenser.

[0006] This application provides a sterilization system for a water dispenser, which adopts the following technical solution: A sterilization system for a water dispenser includes a housing and a pipeline sterilization mechanism, a water sterilization mechanism, a cold-end conveying mechanism, and a hot-end conveying mechanism installed within the housing. The pipeline sterilization mechanism is located below the cold-end conveying mechanism and the hot-end conveying mechanism. One end of each of the cold-end conveying mechanism and the hot-end conveying mechanism is connected to the pipeline sterilization mechanism. The water sterilization mechanism is mounted on the cold-end conveying mechanism. One end of the pipeline sterilization mechanism is connected to a pipeline winding mechanism.

[0007] By adopting the above technical solutions, the integrated pipe sterilization mechanism, water sterilization mechanism, hot end conveying mechanism, cold end conveying mechanism, and pipe winding mechanism within the casing work together to achieve full-process disinfection and protection. This solves the shortcomings of existing technologies, such as water pipe exposure and contamination during water changes and the inability of traditional disinfection to take effect immediately. It also solves the problems of secondary pollution in the water outlet pipe and uneven static sterilization, forming a water quality safety protection system for the entire process of water change, water outlet, and shutdown, thus improving the health and reliability of the water dispenser.

[0008] Preferably, the cold end conveying mechanism includes a first extraction component, a first water inlet, and a first water outlet. The first extraction component is fixedly installed inside the housing. One end of the first water inlet is connected to the pipeline sterilization mechanism, and the other end is connected to the first extraction component. One end of the first water outlet is connected to the first extraction component. The water sterilization mechanism is installed on the first water outlet.

[0009] By adopting the above technical solution, a cold end conveying mechanism is set inside the casing. The first water inlet of the cold end conveying mechanism is connected to the pipeline sterilization mechanism, and drinking water can be obtained from the pipeline sterilization mechanism. The first extraction component conveys the drinking water to the first water outlet. The water sterilization mechanism is installed on the first water outlet. When conveying drinking water at the cold end, the water sterilization mechanism can be combined with the dynamic flow of water to achieve instant sterilization, avoiding secondary pollution of the water during the conveying process.

[0010] Preferably, the first water outlet is provided with a first flow stop, which is fixedly installed on the first water outlet and connected to the output end of the sterilization mechanism.

[0011] By adopting the above technical solution, a pipeline sterilization mechanism, a water sterilization mechanism, a cold end conveying mechanism, and a hot end conveying mechanism are set inside the casing to achieve full-process disinfection and protection. The cold end conveying mechanism includes a first extraction component, a first water inlet, and a first water outlet, which can extract drinking water from bottled water and convey it to the first water outlet. The water sterilization mechanism is installed in the first water outlet and can disinfect the water immediately. A first flow stop component is set in the first water outlet and connected to the output end of the sterilization mechanism, which can effectively prevent the water remaining at the outlet of the first water outlet pipe from flowing back into the water pipe, thus eliminating bacterial growth and contamination.

[0012] Preferably, the hot end conveying mechanism includes a second extraction component, a second water inlet, and a second water outlet. The second extraction component is fixedly installed inside the housing. One end of the second water inlet is connected to the pipeline sterilization mechanism, and the other end is connected to the second extraction component. One end of the second water outlet is connected to the second extraction component. A second flow stop is provided on the second water outlet, and the second flow stop is fixedly installed on the second water outlet.

[0013] By adopting the above technical solution, a cold end conveying mechanism and a hot end conveying mechanism are set inside the casing. The second extraction component of the hot end conveying mechanism can draw drinking water from the pipeline sterilization mechanism and output it through the second water outlet. The second flow stop component on the second water outlet can prevent residual water from flowing back after water is discharged, realizing full-path anti-backflow, blocking residual water backflow, and eliminating the phenomenon of residual water backflow breeding bacteria. Combined with the overall pipeline sterilization mechanism, water sterilization mechanism and pipeline winding mechanism, a water quality safety protection system is formed for the entire process of water change, water discharge and shutdown, improving the health and reliability of the water dispenser.

[0014] Preferably, the pipeline sterilization mechanism includes a sealing chamber and a pipeline sterilization module. The sealing chamber is fixedly installed inside the housing, and the pipeline winding mechanism is connected to the sealing chamber. The pipeline sterilization module is fixedly installed on the sealing chamber, and the output end of the pipeline sterilization module faces into the sealing chamber.

[0015] By adopting the above technical solution, during water replacement, the pipeline winding mechanism can retract the water supply pipes into the sealed chamber. The sealed chamber isolates the external air to prevent the water pipe surface from being contaminated. The pipeline sterilization module can disinfect the water supply pipes in the sealed chamber, preventing external air from contaminating the water pipe surface during water replacement and removing bacteria attached to the water pipe surface.

[0016] Preferably, the sealed chamber is provided with a liquid supply unit, one end of which is connected to the sealed chamber, and the other end is connected to the cold end conveying mechanism and the hot end conveying mechanism respectively.

[0017] By adopting the above technical solution, the liquid supply unit can maintain the connection between the sealed chamber and the first water inlet and the second water inlet, so as to realize that the sealed chamber supplies water to the cold end conveying mechanism and the hot end conveying mechanism.

[0018] Preferably, the pipeline winding mechanism includes a winding shell, a water supply pipe, a guide, and a winding drive. The winding shell is fixedly connected to the sealing chamber. The guide is rotatably installed inside the winding shell. One end of the water supply pipe is laid along the guide, and the other end extends into the sealing chamber and is connected to the liquid supply section. The water supply pipe is elastic. The winding drive is fixedly installed on the outer surface of the winding shell, and one end of the guide is fixedly connected to the winding drive.

[0019] By adopting the above technical solution, the winding drive can drive the guide to rotate, thereby achieving the winding of the flexible water supply pipe and recovering the water supply pipe into the sealed chamber. This avoids external air contamination of the water pipe surface during water replacement, and the connection between the water supply pipe and the liquid supply unit can maintain the connection between the sealed chamber and the inlet and outlet water pipes.

[0020] Preferably, the winding shell is provided with a winding end sterilization module, which is fixedly installed on the winding shell and has its output end facing inwards from the winding shell.

[0021] By adopting the above technical solution, when the bottled water is used up and manually dispensed, the winding drive of the pipeline winding mechanism is activated, driving the guide to rotate and retracting the flexible water supply pipe into the sealed chamber of the pipeline sterilization mechanism. At this time, the end sterilization module on the winding shell is activated, which can perform preliminary sterilization on the water supply pipe. Combined with the pipeline sterilization module in the sealed chamber, a closed-loop protection is formed for the water supply pipe during recycling, avoiding the water pipe from being exposed and contaminated during water change, thus improving the health and reliability of the water dispenser.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. During the water change process, the pipeline winding mechanism retracts the water supply pipes into the sealed chamber. The sealed chamber isolates the air and uses the end sterilization module and the pipeline sterilization module to perform double disinfection on the water supply pipes, which solves the problems of water pipe exposure and contamination during water change and the inability of traditional disinfection to take effect immediately. 2. At the water outlet stage, the water sterilization unit sterilizes the water transported by the cold end conveying unit in real time, avoiding secondary pollution of the water flow during pipeline transportation; 3.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a sterilization system for a water dispenser, see [link to relevant documentation]. Figure 1 and Figure 2 It includes a housing 1 and a pipeline sterilization mechanism 2, a water sterilization mechanism 3, a cold end conveying mechanism 4, and a hot end conveying mechanism 5 installed inside the housing 1; the pipeline sterilization mechanism 2 is located below the cold end conveying mechanism 4 and the hot end conveying mechanism 5; one end of the cold end conveying mechanism 4 and the hot end conveying mechanism 5 are respectively connected to the pipeline sterilization mechanism 2; the water sterilization mechanism 3 is installed on the cold end conveying mechanism 4; one end of the pipeline sterilization mechanism 2 is connected to a pipeline winding mechanism 6.

[0027] Specifically, see Figure 1 and Figure 2 The cold end conveying mechanism 4 includes a first extraction component 41, a first water inlet 42, and a first water outlet 43. The first extraction component 41 is fixedly installed inside the housing 1. One end of the first water inlet 42 is connected to the pipeline sterilization mechanism 2, and the other end is connected to the first extraction component 41. One end of the first water outlet 43 is connected to the first extraction component 41. The water sterilization mechanism 3 is installed on the first water outlet 43.

[0028] In one embodiment, the first extraction component 41 includes a cold-end water pump, which is fixedly installed inside the housing 1 and is used to extract drinking water from bottled water. The first water inlet 42 includes a first water inlet pipe, one end of which is connected to the input end of the cold-end water pump, and the other end is connected to the pipeline sterilization mechanism 2. The first water inlet pipe is used to transport drinking water. The first water outlet 43 includes a first water outlet pipe, which is connected to the output end of the cold-end water pump and is used to output room temperature water or cold water.

[0029] In one embodiment, the water sterilization mechanism 3 includes a UVC flow-through water sterilizer. The UVC flow-through water sterilizer has a sealed water flow channel inside. Water sterilization UVC deep ultraviolet lamp beads or lamp tubes are evenly arranged around the water flow channel. It is also equipped with a corresponding light-transmitting protective cover to isolate the water body from the lamp body, ensure efficient penetration of UVC light, and achieve instant sterilization in combination with dynamic water flow.

[0030] Specifically, see Figure 2 and Figure 3 The first water outlet 43 is provided with a first flow stop 44, which is fixedly installed on the first water outlet 43 and is connected to the output end of the sterilization mechanism.

[0031] In one embodiment, the first flow stop 44 includes a first one-way valve, which is installed on the first water outlet pipe and located at the outlet end of the UVC flow-through water sterilizer. When the water dispenser performs the cold water addition operation, the drinking water passes through the one-way valve. After the water addition operation is completed, the first one-way valve can effectively prevent the water remaining at the outlet of the first water outlet pipe from flowing back into the water pipe, thus preventing bacterial growth and contamination.

[0032] Specifically, see Figure 1 and Figure 2The hot end conveying mechanism 5 includes a second extraction component 51, a second water inlet 52, and a second water outlet 53. The second extraction component 51 is fixedly installed inside the housing 1. One end of the second water inlet 52 is connected to the pipeline sterilization mechanism 2, and the other end is connected to the second extraction component 51. One end of the second water outlet 53 is connected to the second extraction component 51. A second flow stop 54 is provided on the second water outlet 53, and the second flow stop 54 is fixedly installed on the second water outlet 53.

[0033] In one embodiment, the second extraction component 51 includes a hot-end water pump, which is fixedly installed inside the housing 1 and located below the cold-end water pump. The hot-end water pump is used to extract drinking water from bottled water into a kettle or heating tank. The second water inlet 52 includes a second water inlet pipe, one end of which is connected to the input end of the hot-end water pump, and the other end is connected to the pipeline sterilization mechanism 2. The second water inlet pipe is used to transport drinking water. The second water outlet 53 includes a second water outlet pipe, which is connected to the output end of the hot-end water pump and is used to add water to the kettle or heating tank.

[0034] The second flow stop 54 includes a second one-way valve, which is installed on the second water outlet pipe. When the water dispenser performs a water filling operation, drinking water passes through the second one-way valve. After the water filling operation is completed, the second one-way valve can effectively prevent the water remaining at the water outlet from flowing back into the second water outlet pipe, thus preventing bacterial growth and contamination.

[0035] Specifically, see Figure 1 and Figure 3 The pipeline sterilization mechanism 2 includes a sealed chamber 21 and a pipeline sterilization module 22. The sealed chamber 21 is fixedly installed inside the housing 1, and the pipeline winding mechanism 6 is connected to the sealed chamber 21. The pipeline sterilization module 22 is fixedly installed on the sealed chamber 21, with its output end facing inwards from the sealed chamber 21. The sealed chamber 21 is provided with a liquid supply section 23, one end of which is connected to the sealed chamber 21, and the other end is connected to the cold end conveying mechanism 4 and the hot end conveying mechanism 5, respectively.

[0036] In one embodiment, the pipeline sterilization module 22 includes multiple pipeline UVC deep ultraviolet germicidal lamps, which are fixedly installed on the sealed chamber 21 and irradiate into the sealed chamber 21. A sealing gasket is also provided at the connection between the multiple pipeline UVC deep ultraviolet germicidal lamps and the sealed chamber 21.

[0037] The liquid supply unit 23 includes a water supply Y-shaped pipe, one end of which is fixedly connected to the sealed chamber 21 and communicates with the interior of the sealed chamber 21. The first water inlet pipe and the second water inlet pipe are respectively connected to the water supply Y-shaped pipe.

[0038] Specifically, see Figure 1 and Figure 3The pipeline winding mechanism 6 includes a winding shell 61, a water supply pipe fitting 62, a guide member 63, and a winding drive member 64. The winding shell 61 is fixedly connected to the sealing chamber 21. The guide member 63 is rotatably installed inside the winding shell 61. One end of the water supply pipe fitting 62 is laid along the guide member 63, and the other end extends into the sealing chamber 21 and is connected to the liquid supply section 23. The water supply pipe fitting 62 is elastic. The winding drive member 64 is fixedly installed on the outer surface of the winding shell 61, and one end of the guide member 63 is fixedly connected to the winding drive member 64. The winding shell 61 is provided with a roll end sterilization module 65, which is fixedly installed on the winding shell 61, with its output end facing inwards from the winding shell 61.

[0039] In one embodiment, the guide member 63 includes multiple guide wheels arranged in upper and lower layers and rotatably connected to the take-up shell 61. The take-up drive member 64 includes a take-up motor, which is fixedly mounted on the take-up shell 61, and one of the multiple guide wheels is fixedly connected to the output shaft of the take-up motor. The water supply pipe 62 includes a water suction hose, one end of which is connected to a water supply Y-shaped pipe, and the connection end is the end where the water supply Y-shaped pipe connects to the sealing chamber 21. The other end of the water suction hose passes through the multiple guide wheels. The roll-end sterilization module 65 includes a roll-end UVC deep ultraviolet germicidal lamp, which is fixedly mounted on the take-up shell 61, with its output end facing inwards from the take-up shell 61.

[0040] When the bottled water in the water dispenser is used up and the bottle is manually dispensed (water change), the rewind drive 64 initiates the retraction action of the water hose, retracting it into the sealed chamber 21. The sealed chamber 21 is sealed and isolated from the outside, thus preventing external air from contaminating the water pipe surface. Simultaneously with the retraction action of the rewind drive 64, the UVC deep ultraviolet germicidal lamp at the coil end activates to perform preliminary sterilization on the water hose. During the hose retraction action, the UVC deep ultraviolet sterilization module activates to disinfect the water hose inside the sealed chamber 21.

[0041] The working principle of the sterilization system for a water dispenser according to this application is as follows: The integrated pipe sterilization mechanism 2, water sterilization mechanism 3, hot end conveying mechanism 5, cold end conveying mechanism 4, and pipe winding mechanism 6 within the casing 1 work together to achieve full-process disinfection and protection.

[0042] In the water exchange scenario, when the bottled water is used up and manually dispensed, the winding drive 64 (winding motor) of the pipeline winding mechanism 6 is activated, driving the guide wheel (guide 63) to rotate, and retracting the flexible water hose (water supply hose 62) into the sealed chamber 21 of the pipeline sterilization mechanism 2. At the same time, the UVC deep ultraviolet germicidal lamp (winding end sterilization module 65) on the winding shell 61 is activated to perform preliminary sterilization on the hose. The sealed chamber 21 is isolated from the outside through a sealed structure to prevent air pollution. During the hose retraction process, the pipeline UVC deep ultraviolet germicidal lamp (pipeline sterilization module 22) on the sealed chamber 21 is activated simultaneously to perform secondary disinfection on the hose inside the chamber. The water supply Y-shaped pipe (liquid supply section 23) maintains the connection between the sealed chamber 21 and the inlet and outlet water pipes.

[0043] In the water outlet scenario, the cold end water pump (first extraction component 41) of the cold end conveying mechanism 4 is started, and drinking water is drawn from the sealed chamber 21 through the second inlet pipe (second inlet section 52). When it is conveyed through the first outlet pipe (first outlet section 43), the UVC flow-through water sterilizer (water sterilization mechanism 3) installed on the first outlet pipe uses the UVC deep ultraviolet lamp beads / tubes around the internal sealed water flow channel to achieve instant sterilization in combination with the dynamic flow of water. The first one-way valve (first stop component 44) prevents residual water from flowing back after water is discharged. The hot end water pump (second extraction component 51) of the hot end conveying mechanism 5 is started, and drinking water is drawn to the heating kettle / can through the second inlet pipe (second inlet section 52). The second one-way valve (second stop component 54) on the second outlet pipe (second outlet section 53) blocks the residual water from flowing back in this path. The water supply Y-shaped pipe supplies water to both the cold and hot end conveying mechanisms 5.

[0044] This technical solution achieves multiple functions: pipeline sealing and double disinfection during water exchange, with air isolation through the sealing chamber 21 and UVC lamps at the coil end and pipeline working together to sterilize, forming a closed-loop protection during hose recovery; real-time sterilization of the water at the outlet, with a cold-end UVC flow-through sterilizer ensuring sterility of the ambient temperature / cold water terminal and avoiding secondary contamination during transportation; and full-path backflow prevention, with one-way valves at the cold and hot end outlets and coupling positions to completely block residual water backflow.

[0045] The advantages of this technical solution are: it uses physical UVC sterilization without chemical residue, avoiding the impact of disinfectants on taste and health; the various mechanisms are highly interconnected, such as the synchronous start of the winding action and sterilization, and the Y-shaped water supply pipe enabling multi-path water supply, improving operational efficiency; the modular design adapts to existing water dispenser layouts without requiring major equipment modifications. This solution solves the shortcomings of existing technologies, such as water pipe exposure and contamination during water changes, and the inability of traditional disinfection to take effect immediately. It also solves the problems of secondary contamination in the outlet pipe and uneven static sterilization, and eliminates the phenomenon of residual water backflow and bacterial growth caused by an unreasonable layout of a single one-way valve. It forms a water quality safety protection system throughout the entire process of water change, water dispensing, and shutdown, improving the health and reliability of the water dispenser.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
