Description

Technical Field

[0001] This application relates to the field of drinking water equipment technology, specifically to a water bucket lid assembly. Background Technology

[0002] Bottled water is widely used in drinking water systems (such as tea dispensers) in homes and offices due to its convenience. It generally consists of a water bottle and a lid. Traditional bottled water lids have poor antibacterial properties. After the bottle is opened, the water outlet is often exposed to air, allowing microorganisms (such as bacteria and mold) to easily enter the bottle. Especially in tea dispensers, which frequently dispense water, the negative pressure created by the pump inside the bottle causes air to be drawn back in, further accelerating water contamination. Furthermore, existing bottled water systems lack sterilization functions.

[0003] To address this issue, traditional solutions primarily involve installing filtration devices on drinking water equipment. These devices filter and sterilize the water in the tank, but the filter cartridges, mainly made of activated carbon and ion exchange resin, can only adsorb impurities and cannot inactivate microorganisms. Furthermore, they require regular replacement, resulting in high maintenance costs. Another solution is to add disinfectants to the tank, but this can easily lead to chemical residues that compromise water safety and do not meet direct drinking water standards. Therefore, current drinking water equipment tends to use ultraviolet (UV) sterilization for water treatment. The main approach involves installing a UV sterilization device within the equipment. The water tank is connected to this device via a pipe. Water pumped from the tank passes through this pipe, first entering the UV sterilization device for sterilization, before being heated or directly discharged. However, this approach also has limitations. For example, it requires significant modifications to the internal structure and water circuit of the equipment, greatly increasing R&D and production line modification costs. The extended water outlet path also slows down the equipment's water dispensing response. Additionally, the short water flow path within the UV sterilization device results in insufficient UV irradiation, leading to a low sterilization rate. Utility Model Content

[0004] The purpose of this application is to solve the above-mentioned technical problems and provide a water bucket lid assembly that integrates a sterilization module on the water bucket lid, thereby improving the hygiene and safety of the water dispensed from the water bucket and alleviating the high cost problem of traditional solutions requiring external equipment modification.

[0005] The technical solution adopted in this application is as follows:

[0006] A bucket lid assembly includes a bucket lid and a sterilization module. The bucket lid is used to cover the water outlet of a bucket. The bucket lid has an outlet channel formed inside for water to flow out of the bucket. The sterilization module is disposed on the bucket lid and includes a sterilization light source. The sterilization light source is arranged facing the water flow path in the outlet channel. When water in the bucket is discharged outward through the outlet channel, the sterilization light emitted by the sterilization light source covers at least a section of the flow path of the water flowing through the outlet channel.

[0007] In this technical solution, a sterilization module is integrated into the water bucket lid. The sterilization light source is arranged facing the water flow path within the water outlet channel. When water is dispensed from the bucket, the water flows through the water outlet channel of the bucket lid, and the sterilization module irradiates the water outlet channel with sterilization light, covering at least a section of the water flow path to achieve irradiation sterilization and effectively improve the hygiene and safety of the dispensed water. Furthermore, by integrating the sterilization module into the water bucket lid, which is installed at the water outlet port along with the lid, this application addresses the high R&D and production line modification costs associated with adding sterilization devices to drinking water equipment. It also helps simplify the layout of water pipes, shorten pipe length, and improve water dispensing response speed. Preferably, the sterilization light source is a UV lamp, suitable for efficient sterilization of drinking water.

[0008] The water outlet channel includes an inlet, an outlet, and an extension channel connecting the inlet and the outlet. The inlet is connected to the outlet port of the water tank. The extension path length of the extension channel is greater than the straight-line distance between the inlet and the outlet. The sterilization light emitted by the sterilization light source covers at least a portion of the extension channel.

[0009] In this technical solution, by setting an extended flow channel, it is helpful to extend the flow path of water in the outlet flow channel and the irradiation time of the bactericidal light on the water flow, so that the water flow can be irradiated for a longer time to enhance the bactericidal effect and improve the bactericidal rate. At the same time, the design of the extended flow channel can make reasonable use of the internal space of the water bucket lid.

[0010] The extended flow channel is configured as a continuously curved flow channel structure on a plane, with the extended flow channel opening upwards, and the sterilization light source is positioned above the extended flow channel.

[0011] In this technical solution, the extended flow channel is open upwards, and the sterilization light source is located above. The sterilization light source only needs to shine downwards to cover a large area of ​​the extended flow channel. Moreover, the continuous curved design of the extended flow channel allows the water to be more fully exposed to the sterilization light when flowing in the curved flow channel, increasing the contact area and time between the sterilization light and the water flow, and improving the sterilization efficiency.

[0012] The extended flow channel is designed as a planar spiral flow channel structure, and the water inlet is located in the middle of the spiral of the extended flow channel, so that after the water enters the extended flow channel, it flows spirally to the outer periphery of the spiral of the extended flow channel.

[0013] In this technical solution, the extended flow channel is a planar spiral shape, with the water inlet in the middle of the spiral and the outlet of the extended flow channel on the outer periphery of the spiral. This effectively extends the water flow path within the limited space inside the water bucket lid, allowing the water to form a longer flow trajectory within the spiral flow channel. The sterilization light can cover more sections, greatly increasing the interaction time and range between the sterilization light and the water flow, effectively improving the sterilization effect. Furthermore, the spiral structure is compact and saves space.

[0014] The water bucket lid has a sterilization chamber, and the sterilization module is disposed in the sterilization chamber. The water outlet channel includes an inlet formed at the bottom of the sterilization chamber and an outlet formed at the top of the sterilization chamber. The inlet is connected to the water outlet port of the water bucket. The sterilization module is spaced apart from the inner wall of the sterilization chamber, and the water outlet channel is formed in the space between the sterilization module and the inner wall of the sterilization chamber.

[0015] In this technical solution, the sterilization module is set inside the sterilization chamber to form a closed sterilization environment, which helps to reduce external pollution. The water inlet is at the bottom of the sterilization chamber and the water outlet is at the top of the sterilization chamber, so that the water flows from bottom to top through the sterilization chamber. This ensures that the water flow is fully irradiated by the sterilization light source inside the sterilization chamber, and the space of the sterilization chamber is used to carry out comprehensive sterilization of the water flow, ensuring the effectiveness and sufficiency of sterilization.

[0016] The sterilization module and the bottom wall of the sterilization chamber form a water inlet space, the sterilization module and the top wall of the sterilization chamber form a water outlet space, and the sterilization module and the side wall of the sterilization chamber form a transition space connecting the water inlet space and the water outlet space. The water inlet is located at the center of the bottom wall of the water inlet space, and the water outlet is located at the center of the top wall of the water outlet space, so that the water entering the sterilization chamber first diffuses towards the transition space through the water inlet space and then converges towards the center of the water outlet space.

[0017] In this technical solution, the sterilization module and the sterilization chamber form an inlet space, an outlet space, and a transition space. The inlet and outlet are located in the center, so that the water flow enters the sterilization chamber through the inlet and first diffuses and then converges as it flows from bottom to top. This flow pattern makes the water flow more evenly distributed in the sterilization chamber, expands the coverage of the sterilization light, and allows all parts of the water flow to fully contact the sterilization light, improving the uniformity and effect of sterilization and avoiding the problem of insufficient sterilization when the water flow is directly passed through.

[0018] The bottom wall of the sterilization chamber is provided with supporting guide ribs protruding towards the water inlet space, and the upper end of the supporting guide ribs supports the sterilization module. When water enters the water inlet space from the water inlet, the water flow diffuses along the flow channel formed by the guide ribs to the transition space, and the flow path is covered by the sterilization light emitted by the sterilization light source.

[0019] In this technical solution, the supporting guide ribs on the bottom wall of the sterilization chamber support the sterilization module and guide the water flow to diffuse along the flow channel to the transition space and be covered by the sterilization light. Therefore, the supporting guide ribs not only play a supporting role, but also regulate the water flow path, so that the water flows according to the preset flow channel, ensuring that the water flow is always within the irradiation range of the sterilization light during the diffusion process, thereby enhancing the reliability and effectiveness of sterilization.

[0020] The sterilization chamber is provided with a stop rib, which stops and restricts the translation of the sterilization module; and / or, the sterilization chamber is provided with a locking rib, which stops and restricts the rotation of the sterilization module.

[0021] In this technical solution, the stop ribs in the sterilization chamber restrict the translation of the sterilization module, and the locking ribs restrict the rotation. The sterilization module is fixed by a mechanical structure to prevent it from shifting or rotating during use, ensuring the stability of the sterilization light source position, thereby ensuring that the sterilization light always accurately irradiates the water flow path and maintaining the stability of the sterilization effect.

[0022] The bucket lid is designed as a split structure, including an upper lid and a lower lid. When the upper lid and the lower lid are put together, they form the sterilization chamber and clamp and limit the sterilization module from top to bottom.

[0023] In this technical solution, the bucket lid is designed as a split upper and lower lid, which enables quick assembly and maintenance. When the two are combined, they form a sterilization chamber and clamp and limit the sterilization module, which facilitates the installation of the sterilization module.

[0024] The sterilization module includes a light-transmitting lampshade and a cover plate. The sterilization light source is disposed in a sealed cavity formed by the light-transmitting lampshade and the cover plate, and the sterilization light source emits sterilization light outward through the light-transmitting lampshade.

[0025] In this technical solution, the light-transmitting lampshade and cover plate of the sterilization module form a sealed cavity to accommodate the sterilization light source. The sterilization light is emitted through the light-transmitting lampshade. The sealed cavity can protect the sterilization light source from moisture, dust and other factors, and extend the service life of the light source. At the same time, the light-transmitting lampshade ensures the effective transmission of the sterilization light, ensuring the sterilization effect. Moreover, the structural design facilitates the installation and protection of the light source. Attached Figure Description

[0044] In the embodiments of this application, reference is made to Figures 1 to 5 As shown, a bucket lid assembly is provided. For ease of explanation and understanding, the following descriptions are based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is merely a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0045] Example 1:

[0046] like Figure 1 and Figure 2 As shown, the bucket lid assembly includes a bucket lid 1 and a sterilization module 2. The bucket lid 1 is used to cover the water outlet of the bucket 6. A water outlet channel 11 is formed inside the bucket lid 1 to supply water from the bucket 6 to the outside. The sterilization module 2 is disposed on the bucket lid 1 and includes a sterilization light source 21. The sterilization light source 21 is arranged facing the water flow path in the water outlet channel 11. When the water in the bucket 6 is discharged outward through the water outlet channel 11, the sterilization light emitted by the sterilization light source 21 covers at least a section of the flow path of the water flowing through the water outlet channel 11.

[0047] Figure 1The water bucket 6 shown is merely an illustrative structure for the purpose of describing and understanding the water bucket lid assembly and should not be construed as limiting this application. The water bucket lid assembly of this application can be applied to bottled water buckets in tea bar machines and water dispensers, utilizing the sterilization module 2 to sterilize the purified water inside the bottle. Furthermore, this water bucket lid assembly can also be adapted to other types of water buckets, such as… Figure 2 The diagram shows the bucket lid assembly installed on the bucket 6. To facilitate the fit between the bucket lid assembly and the bucket 6, a bottom cover 3 can be provided for fitting with the bucket 6, and the bucket lid 1 is fixedly mounted on the bottom cover 3. Specifically, a water pump can be connected downstream of the water outlet channel 11, and a suction pipe 4 can be connected upstream of the water outlet channel 11. The suction pipe 4 is inserted into the bucket 6. When the water pump is working, the pump suction draws water from the bucket 6, and the sterilization module 2 irradiates and sterilizes the water as it flows through the water outlet channel 11. Therefore, in this solution, a sterilization module 2 is integrated on the bucket lid 1, and the sterilization light source 21 is arranged facing the water flow path in the water outlet channel 11. When water is discharged from the bucket 6, the water flows through the water outlet channel 11 of the bucket lid 1, and the sterilization module 2 irradiates the water outlet channel 11 with sterilization light, so that the sterilization light covers at least a section of the water flow path, achieving irradiation sterilization and effectively improving the hygiene and safety of the discharged water. Furthermore, this application integrates the sterilization module 2 onto the water bucket lid 1, which is installed at the water outlet of the water bucket along with the lid 1. This improves upon the high R&D and production line modification costs associated with adding sterilization devices to drinking water equipment, and also helps simplify the layout of water pipes, shorten pipe length, and improve water outlet response speed. Preferably, the sterilization light source 21 is a UV lamp, suitable for efficient sterilization of drinking water.

[0048] As a preferred example in this embodiment, such as Figure 2 , Figure 3 and Figure 4 As shown, the water outlet channel 11 includes an inlet 111, an outlet 112, and an extension channel 113 connecting the inlet 111 and the outlet 112. The inlet 111 is connected to the outlet port of the water bucket 6. The extension path length of the extension channel 113 is greater than the straight-line distance between the inlet 111 and the outlet 112. The sterilization light emitted by the sterilization light source 21 covers at least a portion of the extension channel 113. Those skilled in the art will understand that the water outlet channel of a traditional water bucket lid is a vertical channel. In this solution, in order to better perform sterilization, by setting an extension channel 113 in the water outlet channel, it is helpful to extend the flow path of the water in the water outlet channel 11 and the irradiation time of the sterilization light on the water flow, so that the water flow can be irradiated for a longer time to enhance the sterilization effect and improve the sterilization rate. At the same time, the design of the extension channel 113 can make reasonable use of the internal space of the water bucket lid 1.

[0049] In a preferred embodiment, the extended flow channel 113 can be configured as a continuously curved flow channel structure on a plane, with the extended flow channel 113 opening upwards, and the sterilization light source 21 positioned above the extended flow channel 113. The planar flow channel structure has a large extension area, allowing the water flow to spread as flatly as possible on the extended flow channel 113. The sterilization light source 21 only needs to shine downwards to cover a large area of ​​the extended flow channel 113 with sterilization light, which can penetrate the water flow completely. Moreover, the continuous curved design of the extended flow channel 113 allows the water flow to be more fully exposed to the sterilization light when flowing within the curved flow channel, increasing the contact area and time between the sterilization light and the water flow, thereby improving sterilization efficiency.

[0050] Furthermore, such as Figure 4 As shown, the extended flow channel 113 is designed as a planar spiral flow channel structure. The inlet 111 is located in the middle of the spiral of the extended flow channel 113, allowing water to flow spirally to the outer periphery of the spiral after entering the extended flow channel 113. In this technical solution, after the water enters from the inlet 111, it flows along the spiral trajectory defined by the extended flow channel 113 towards the outer periphery of the spiral. The entire spiral flow process is basically under the irradiation and sterilization state of the sterilizing light. Combined with the planar spiral shape of the extended flow channel 113, the water flow path is effectively extended within the limited space inside the water bucket lid 1, allowing the water to form a longer flow trajectory within the spiral flow channel. The sterilizing light can cover more sections, greatly increasing the interaction time and range between the sterilizing light and the water flow, effectively improving the sterilization effect. Moreover, the spiral structure is compact and saves space. As an alternative, the extended flow channel can also be designed with other suitable flow channel structures, such as a meandering flow channel structure consisting of multiple U-shaped segments connected in sequence. Regarding the formation method of the extended flow channel 113, this application does not limit it. For example, some raised ribs or recessed areas can be provided on the bucket lid 1, and the extended flow channel 113 can be formed by the ribs or the internal space of the recessed area.

[0051] Example 2:

[0052] The structure and principle of this embodiment 2 are basically the same as those of embodiment 1, except that: Figure 2As shown, a sterilization chamber 12 is provided inside the water tank lid 1, and a sterilization module 2 is disposed inside the sterilization chamber 12. An inlet 111 is formed at the bottom of the sterilization chamber 12, and an outlet 112 is formed at the top of the sterilization chamber 12. The sterilization module 2 is spaced apart from the inner wall of the sterilization chamber 12, and a water flow channel 11 is formed within the space between the sterilization module 2 and the inner wall of the sterilization chamber 12. By placing the sterilization module 2 inside the sterilization chamber 12, a closed sterilization environment is formed, which helps reduce external contamination. The inlet 111 is below the sterilization chamber 12, and the outlet 112 is above the sterilization chamber 12, allowing water to flow from bottom to top through the sterilization chamber 12. This ensures that the water is fully irradiated by the sterilization light source 21 within the sterilization chamber 12, utilizing the space of the sterilization chamber 12 to comprehensively sterilize the water, ensuring the effectiveness and sufficiency of sterilization. Since the sterilization light source 21 requires electricity for sterilization, in specific implementation, it is preferable to install a power interface 5 on the water tank lid 1. The power interface 5 is located on the outside of the water outlet channel 11. A wire hole can be provided on the wall of the sterilization chamber 12 for the power interface 5 to be connected to the sterilization light source 21. To ensure the airtightness of the sterilization chamber 12, the wire hole can be sealed by means of potting glue or other methods. In addition, since the sterilization module 2 is located inside the sterilization chamber 12, to ensure the sterilization effect, when this embodiment and embodiment 1 are used in combination, the extended flow channel 113 described in embodiment 1 can be formed inside the sterilization chamber 12 and located below the sterilization module 2.

[0053] As a preferred example in this embodiment, such as Figure 2 and Figure 5 As shown, the sterilization module 2 and the bottom wall of the sterilization chamber 12 form a water inlet space 121, the sterilization module 2 and the top wall of the sterilization chamber 12 form a water outlet space 122, and the sterilization module 2 and the side walls of the sterilization chamber 12 form a transition space 123 connecting the water inlet space 121 and the water outlet space 122. The water inlet 111 is located at the center of the bottom wall of the water inlet space 121, and the water outlet 112 is located at the center of the top wall of the water outlet space 122, so that the water entering the sterilization chamber 12 first diffuses through the water inlet space 121 toward the transition space 123 and then converges toward the center of the water outlet space 122. Specifically, Figure 5 The middle arrow represents the flow path of the water after entering the sterilization chamber 12. The water flows into the sterilization chamber 12 through the inlet 111 and first diffuses and then converges as it flows upward. This flow pattern makes the water flow more evenly distributed in the sterilization chamber 12, expands the coverage of the sterilization light, and allows all parts of the water flow to fully contact the sterilization light, improving the uniformity and effect of sterilization and avoiding the problem of insufficient sterilization when the water flows directly through.

[0054] Furthermore, such as Figures 2 to 4As shown, the bottom wall of the sterilization chamber 12 is provided with supporting guide ribs 13 protruding towards the water inlet space 121, and the upper end of the supporting guide ribs 13 supports the sterilization module 2. When water enters the water inlet space 121 from the water inlet 111, the water flow diffuses along the flow channel formed by the guide ribs to the transition space 123, and the flow path is covered by the sterilization light emitted by the sterilization light source 21. In this technical solution, the supporting guide ribs 13 on the bottom wall of the sterilization chamber 12 support the sterilization module 2, and at the same time guide the water flow to diffuse along the flow channel to the transition space 123 and be covered by the sterilization light. Therefore, the supporting guide ribs 13 not only play a supporting role, but also regulate the water flow path, so that the water flow flows according to the preset flow channel, ensuring that the water flow is always within the irradiation range of the sterilization light during the diffusion process, thereby enhancing the reliability and effectiveness of sterilization. Moreover, Figures 2 to 4 The diagram mainly illustrates the combination of Embodiment 1 and Embodiment 2. That is, the flow channel enclosed by the supporting guide ribs 13 constitutes the extended planar spiral flow channel 113 described in Embodiment 1. Therefore, after the water flows in, it flows along the supporting guide ribs 13 from the center of the spiral to the outer periphery of the spiral. When it reaches the outer periphery of the spiral, it enters the transition space 123 and is irradiated by the bactericidal light source 21 above during the flow within the supporting guide ribs 13.

[0055] In addition, such as Figure 3 and Figure 4 As shown, the sterilization chamber 12 is provided with stop ribs 14 and locking ribs 15. The stop ribs 14 stop and restrict the translation of the sterilization module 2, and the locking ribs 15 stop and restrict the rotation of the sterilization module 2. The sterilization module 2 is fixed by a mechanical structure to prevent displacement or rotation during use, ensuring the stable position of the sterilization light source 21, thereby ensuring that the sterilization light always accurately irradiates the water flow path and maintains the stability of the sterilization effect. Preferably, multiple stop ribs 14 can be provided at intervals along the circumference of the sterilization chamber 12. The stop ribs 14 and the stop of the sterilization module 2 separate the sterilization module 2 from the side wall of the sterilization chamber 12, thereby forming a transition space 123. In addition, locking grooves 151 can be provided on the locking ribs 15, and protrusions 231 can be provided on the sterilization module 2. The locking grooves 151 and protrusions 231 cooperate to restrict the rotation of the sterilization module 2.

[0056] As a preferred example in this embodiment, such as Figure 1 and Figure 2As shown, the water bucket lid 1 is a split structure, including an upper lid 16 and a lower lid 17. When the upper lid 16 and the lower lid 17 are fitted together, they form a sterilization chamber 12 and clamp and limit the sterilization module 2. In this technical solution, the water bucket lid 1 is designed with a split structure of upper lid 16 and lower lid 17, which enables quick assembly and maintenance. When the two are fitted together, they form a sterilization chamber 12 and clamp and limit the sterilization module 2, facilitating the installation of the sterilization module 2. Preferably, to improve the sealing performance of the sterilization chamber 12, the upper lid 16 and the lower lid 17 can be fitted together by ultrasonic welding. In addition, baffles can be provided on the top of the upper lid 16 or the sterilization module 2, with the top of the upper lid 16 and the top of the sterilization module 2 separated by baffles, thereby forming a water outlet space 122.

[0057] As a preferred embodiment of this application, such as Figure 1 and Figure 2 As shown, in all the aforementioned embodiments, the sterilization module 2 can include a light-transmitting lampshade 22 and a cover plate 23. The sterilization light source 21 is disposed within the sealed cavity formed by the light-transmitting lampshade 22 and the cover plate 23. The sterilization light source 21 emits sterilization light outward through the light-transmitting lampshade 22. The light-transmitting lampshade 22 and the cover plate 23 of the sterilization module 2 form a sealed cavity to accommodate the sterilization light source 21. The sterilization light is emitted through the light-transmitting lampshade 22. The sealed cavity can protect the sterilization light source 21 from moisture, dust, etc., extending the service life of the light source. At the same time, the light-transmitting lampshade 22 ensures the effective transmission of the sterilization light, ensuring the sterilization effect. Moreover, the structural design facilitates the installation and protection of the light source.
