[0002] With the improvement of living standards, drinking water equipment has become widely popular due to its adjustable temperature and convenient instant drinking water. Currently, drinking water equipment is usually equipped with a water tank. The water from the water purifier is first filled into the water tank, and when in use, the drinking water equipment draws water from the tank to dispense to the user.

[0003] However, when the water tank is not used for a long time or after the machine has been in use for an extended period, bacteria or algae may grow inside. These substances can affect the taste and safety of drinking water. To address this issue, UV lamps are typically installed in the water tank. However, the range of UV light is limited, resulting in blind spots in the disinfection process and affecting the effectiveness of the disinfection. Utility Model Content

[0040] See Figure 1 , Figure 1The diagram shows a structural schematic of a water storage device according to an embodiment of this application. The water storage device provided in this embodiment includes a water tank 60 and a disinfection component disposed in the water tank 60. A water storage cavity 61 is formed in the water tank 60. The water storage cavity 61 is used to store purified water or other liquids that can be used for drinking by users. The disinfection component is used to disinfect the inner wall of the water storage cavity 61 to avoid the problem of bacteria or moss growing on the inner wall of the water storage cavity 61 after long-term disuse or long service life.

[0041] Specifically, the disinfection assembly includes a drive component 10, a movable bracket 20, a disinfection lamp source 30, and a reflector 40. The drive component 10 is mounted on the water tank 60, and the movable bracket 20 is movably mounted on the water tank 60. The movable bracket 20 is connected to the drive component 10 in a transmission manner. The drive component 10 is used to drive the movable bracket 20 to rotate around a rotation axis so that the movable bracket 20 can rotate relative to the water tank 60.

[0042] The disinfection lamp source 30 is mounted on the movable support 20 and is used to output disinfection light 31. The reflector 40 is mounted on the movable support 20 and has a reflective surface 41. The reflective surface 41 is used to change the transmission path of the disinfection light 31 that shines on it, so that after the disinfection light 31 shines on the reflective surface 41, the disinfection light 31 can be reflected by the reflective surface 41, so that the disinfection light 31 can shine on the side wall of the water storage cavity 61 through the reflective surface 41, thereby disinfecting and sterilizing the side wall of the water storage cavity 61.

[0043] In practical use, please refer to Figure 5 The movable bracket 20 is located on top of the water tank 60, and the reflector 40 is located inside the water storage cavity 61, with the reflecting surface 41 facing the circumferential sidewall of the water storage cavity 61. When the disinfection light 31 does not pass through the reflector 40, it can only irradiate the bottom of the water storage cavity 61 and cannot disinfect the sidewall of the water storage cavity 61. However, during the transmission of the disinfection light 31, after being reflected by the reflecting surface 41 of the reflector 40, the disinfection light 31 can irradiate the circumferential sidewall of the water storage cavity 61, thereby disinfecting and sterilizing the circumferential sidewall of the water storage cavity 61.

[0044] Furthermore, as the reflector 40 rotates with the movable bracket 20, the reflective surface 41 faces different directions. Thus, when the disinfection lamp source 30 outputs disinfection light 31, it works in conjunction with the drive component 10 to rotate the movable bracket 20 around its rotation axis, thereby causing the movable bracket 20 to rotate both the disinfection lamp source 30 and the reflector 40. During this rotation, the reflective surface 41 of the reflector 40 faces different directions, allowing the disinfection light 31 to cover a wider area. Specifically... Figure 1In the example, as the reflector 40 rotates with the movable support 20, the disinfection light 31 can sequentially cover the circumferential sidewall of the water storage cavity 61, thereby disinfecting and sterilizing each position of the circumferential sidewall of the water storage cavity 61, reducing disinfection dead corners and improving disinfection effect.

[0045] The aforementioned disinfection component alters the transmission path of the disinfection light 31 through the reflective surface 41 of the reflector 40, enabling the disinfection light 31 to reach the dead corners inside the water tank 60. In conjunction with the drive component 10, the movable support 20 rotates, allowing the reflector 40 to illuminate the disinfection light 31 to every corner inside the water tank 60 through the reflective surface 41 as the movable support 20 rotates, thereby reducing disinfection dead corners and improving the disinfection effect.

[0046] In some embodiments of this application, the reflective surface 41 intersects with but is not perpendicular to the disinfection light 31 illuminating it, thereby allowing the disinfection light 31 to irradiate the periphery of the disinfection lamp source 30 under the reflection of the reflective surface 41. It is understood that in other embodiments, the reflective surface 41 may be perpendicular to the disinfection light 31, so that some of the disinfection light 31 can be reflected to a position on the side of the disinfection lamp source 30 away from the reflector 40, thereby disinfecting that position. In actual use, the orientation of the reflective surface 41 can be selected according to actual usage requirements and is not limited here.

[0047] In some embodiments of this application, see [reference] Figure 2 The reflective surface 41 is convex. When the disinfection light 31 shines on the convex surface, the convex surface diffuses the disinfection light 31, thereby further expanding the irradiation range of the disinfection light 31. Specifically... Figure 1 In this embodiment, the convex surface is enlarged so that a portion of the disinfection light 31 can irradiate the side wall of the water storage chamber 61, and another portion can irradiate the bottom wall of the disinfection chamber, thereby simultaneously disinfecting and sterilizing the side wall and the bottom wall.

[0048] It should be noted that, in order to allow the orientation of the reflective surface 41 to change as the reflector 40 rotates with the movable support 20, the central axis of the reflective surface 41 is intersected with the rotation axis of the movable support 20, so as to prevent the reflective surface 41 from always facing the same position during the rotation of the reflector 40. The central axis of the reflective surface 41 refers to the perpendicular line passing through the center of its own plane.

[0049] In some embodiments of this application, the disinfection lamp source 30 is an ultraviolet lamp. However, in actual use, the disinfection light 31 output by the ultraviolet lamp is a divergent light. When the reflective surface 41 is convex, although the irradiation area can be further increased, the disinfection light 31 will be diffused twice, resulting in insufficient intensity of the disinfection light 31, thereby affecting the disinfection and sterilization effect.

[0050] To this end, the disinfection assembly also includes a lens 51, which is positioned between the disinfection lamp source 30 and the reflector 40. The lens 51 converts the disinfection light 31 passing through it into parallel light and outputs the parallel light onto the reflector 40. In this way, the lens 51 first concentrates the divergent light output from the ultraviolet lamp, thereby increasing the intensity of the disinfection light 31. Then, the concentrated disinfection light 31 is reflected by the reflector 40, which increases the coverage area of ​​the disinfection light 31. This ensures sufficient coverage area while avoiding insufficient intensity of the disinfection light 31.

[0051] Concentrating the disinfection light 31 using a single lens 51 would result in a larger lens 51, which is not conducive to the disinfection of the small water tank 60. Therefore, in some other embodiments, see [reference needed]. Figure 3 and Figure 4 The disinfection assembly also includes a lens group 50, which comprises multiple lenses 51. All lenses 51 are evenly distributed between the disinfection lamp source 30 and the reflector 40, and each lens 51 has a different radius. It should be noted that... Figure 3 and Figure 4 The middle part shows a simplified shape of the lens group 50. Each protrusion on the lens group 50 represents a lens 51. The type of lens 51 can be selected according to actual needs, such as a convex lens 51, a concave lens 51, a biconcave lens, or a biconvex lens 51.

[0052] Thus, the entire lens group 50 can convert the sterilizing light 31 passing through it into parallel light. Compared to a single lens 51, multiple reflections of the sterilizing light 31 by multiple lenses 51 reduce the bulk of each lens 51. Specifically, each lens 51 is a concentric ring, and each ring lens 51 has a different radius and a high-transmittance material, thereby enabling precise adjustment of the phase distribution of ultraviolet light. Specifically, the innermost lens 51 in the lens group 50 has a radius of R1, increasing by ΔR outwards until the outermost lens 51 has a radius of Rn, ensuring that the ultraviolet light can be efficiently focused and propagated onto the reflector 40 after passing through the lens group 50.

[0053] In some embodiments of this application, the movable bracket 20 has a receiving cavity 21 and a light outlet 22 communicating with the receiving cavity 21. The disinfection lamp source 30 is disposed inside the receiving cavity 21, and the reflector 40 is disposed outside the receiving cavity 21, with a reflective surface 41 formed on the side of the reflector 40 facing the light outlet 22. In this way, the light emitted by the disinfection lamp source 30 will be emitted from the light outlet 22 and reflected by the reflector 40 into the surrounding environment.

[0054] Furthermore, the aforementioned lens 51 or lens group 50 is disposed at the light outlet 22, so that the disinfection light 31 output from the light outlet 22 is a parallel light extending along the axial direction of the light outlet 22. In order to ensure that all the disinfection light 31 can be reflected by the reflector 40, the projection of the reflector 40 on the movable bracket 20 along the axial direction of the light outlet 22 covers the light outlet 22, so that the parallel light output from the light outlet 22 can all illuminate the reflector and be reflected by the reflector.

[0055] In some specific embodiments, one end of the reflector 40 is connected to one side of the movable bracket 20 in the radial direction of the light outlet 22, and the other end extends longitudinally toward the other side of the light outlet 22 in the radial direction. Furthermore, the two opposite ends of the reflector 40 have a height difference along the axial direction of the light outlet 22. That is, the reflector 40 is inclined relative to the plane of the light outlet 22, so that the reflective surface 41 can face the sidewall of the water storage cavity 61. This allows the disinfection light 31 emitted from the light outlet 22 to irradiate the sidewall of the water storage cavity 61 after irradiating the reflective surface 41.

[0056] In some specific embodiments, the axis of the light-emitting port 22 is coaxial with the rotation axis. Thus, when the driving member 10 drives the movable support 20 to rotate, the direction of the disinfection light 31 output from the light-emitting port 22 remains unchanged because the axis of the light-emitting port 22 is coaxial with the rotation axis. However, when the movable support 20 rotates, the reflector rotates around the rotation axis, thereby changing the orientation of the reflective surface 41 on the reflector. Furthermore, as the reflector rotates with the movable support 20, the light-emitting surface causes the disinfection light 31 to move along the circumferential sidewall of the water storage cavity 61, thereby disinfecting and sterilizing the circumferential sidewall of the water storage cavity 61.

[0057] When the reflective surface 41 is convex, the convex surface protrudes towards the light outlet. After the disinfection light 31 output from the light outlet 22 is reflected by the reflective surface 41, part of the disinfection light 31 will be reflected to the bottom wall of the water storage cavity 61. With the rotation of the reflector along the movable bracket 20, the disinfection light 31 that shines on the bottom wall of the water storage cavity 61 will move along the bottom wall of the water storage cavity 61, thereby disinfecting the bottom wall and side wall of the water storage cavity 61 at the same time, further reducing the disinfection dead corners.

[0058] In some embodiments of this application, the disinfection assembly further includes a speed reduction structure. The drive component 10 has an output shaft rotatable about its own axis. The speed reduction structure drives the output shaft and the movable support 20, and is used to reduce the rotational speed of the output shaft. The drive component 10 is a motor, and the speed reduction structure is a reduction gear set. The motor's rotational speed is 10-30 RPM. By reducing the rotational speed of the motor through the reduction gear set, the movable support 20 achieves stable rotational movement.

[0059] Furthermore, a rotating shaft 23 is provided on the movable bracket 20. The rotating shaft 23 is rotatably mounted on the water tank 60, with one end of the rotating shaft 23 located in the water storage cavity 61 and the other end located outside the water storage cavity 61. The driving component 10 is connected to the end of the rotating shaft 23 located outside the water storage cavity 61, thereby setting the driving component 10 outside the water tank 60 to prevent the liquid inside the water tank 60 from affecting the normal operation of the driving component 10.

[0060] Optionally, the rotating shaft 23 is made of stainless steel 304, which has rust-proof and corrosion-resistant properties. At the same time, a sealed bearing is installed between the rotating shaft 23 and the water tank 60 to prevent water leakage from the water tank 60.

[0061] In some embodiments of this application, the water storage device further includes a water quality sensor disposed within the water tank 60. The water quality sensor is used to detect water quality parameters inside the water tank 60 in real time, including turbidity and pH value. The water quality sensor is communicatively connected to a controller for controlling the disinfection lamp source 30. The controller controls the irradiation intensity of the disinfection lamp source 30 based on the detection data from the water quality sensor. At the same time, the controller can also control the rotation speed of the drive component 10, thereby optimizing the irradiation range and intensity of the disinfection light beam 31.

[0062] Optionally, when the water quality sensor detects a large number of bacteria adhering to the inner wall of the water tank 60, the controller increases the output power of the disinfection lamp source 30 to 120-150 mW / cm². 2 The rotation speed of the movable support 20 is reduced to 20 RPM to ensure that the disinfection light 31 can evenly cover all areas of the inner wall of the water storage chamber 61.

[0063] Furthermore, the disinfection component also includes a temperature sensor, which is used to detect the operating temperature of the disinfection lamp source 30. When the temperature exceeds the set value, such as 80°C, the controller will automatically reduce the power output of the ultraviolet lamp or stop working to prevent overheating damage.

[0064] In some embodiments of this application, a reflective layer is provided on the inner wall surface of the water storage cavity 61. After the disinfection light 31 shines on the inner wall of the water storage cavity 61, it will be reflected twice by the reflective layer on the inner wall surface, so that the disinfection light 31 can shine on other parts of the water storage cavity 61 under the reflection of the reflective layer, further reducing disinfection dead corners and improving the disinfection effect.

[0065] This application embodiment also provides a drinking water device, including the water storage device as described in any of the above embodiments. The drinking water device also includes a water outlet component, which is connected to the water tank 60 of the water outlet device and is used to output the liquid in the water tank 60 to the user for consumption.

[0066] The above-mentioned water storage device has at least the following advantages:

[0067] By altering the transmission path of the disinfection light 31 through the reflective surface 41 of the reflector 40, the disinfection light 31 can reach the dead corners inside the water tank 60. In conjunction with the drive component 10, the movable bracket 20 is rotated, allowing the reflector 40 to irradiate the disinfection light 31 into every corner of the water tank 60 through the reflective surface 41 as the movable bracket 20 rotates, thereby reducing disinfection dead corners and improving the disinfection effect.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
