[0034] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0035] It should be noted that in the description of this utility model, terms such as "inner", "outer", "upper", "lower", "top", and "bottom" that indicate direction or positional relationship are based on the direction or positional relationship shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0036] Furthermore, it should be noted that in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Based on the background art, existing water purification equipment's storage tanks suffer from algae growth under sunlight. This utility model provides a water storage tank and a water purification device including the storage tank. The aim is to reduce algae photosynthesis by setting the storage tank so that sunlight can reach the water chamber and the water level can be clearly seen, and to reduce algae growth by filtering out light within a specific wavelength range, thereby ensuring the safety of the water quality in the storage tank.

[0038] Specifically, such as Figure 1 As shown, in a first aspect, the present invention provides a water storage tank 1, which has a water storage cavity capable of storing water. The water storage tank 1 is configured to allow sunlight to shine into the water storage cavity, and the water storage tank 1 is also configured to filter out light within a specific wavelength range to inhibit algae in the water storage cavity from photosynthesizing.

[0039] For example, such as Figure 1 As shown, the water storage tank 1 of this utility model is rectangular and is arranged vertically. The water storage cavity inside the water storage tank 1 is used to hold water. Sunlight can shine into the water storage cavity through the side wall of the water storage tank 1, so the water level in the water storage cavity can be seen through the side wall of the water storage tank 1. A scale is provided on the side wall of the water storage tank 1, so that the remaining amount of water in the water storage cavity can be accurately identified. The water storage tank 1 can also filter out light in a specific wavelength range. By filtering out light that is conducive to algae photosynthesis, the algae in the water storage tank 1 cannot perform photosynthesis by absorbing light, thereby inhibiting the growth of algae in the water storage tank 1 and ensuring the safety of the water quality in the water storage tank 1.

[0040] In the first preferred case, such as Figure 1 As shown, the water storage tank 1 of this utility model includes a shell and a filter membrane. The filter membrane is attached to the outer wall and / or inner wall of the shell, and the water storage cavity is located inside the shell. The filter membrane can filter out light within a specific wavelength range.

[0041] For example, such as Figure 1 As shown, the shell of the water storage tank 1 of this utility model is transparent, allowing light to shine into the water inside the tank. A filter film is tightly attached to the outer wall of the shell. The filter film can filter out light within a specific wavelength range that is conducive to photosynthesis by algae, thereby inhibiting the growth of algae and killing algae and other microorganisms.

[0042] In the second preferred case, such as Figure 1 As shown, the water storage tank 1 of this utility model includes a shell, which is made of a light-filtering material and is capable of filtering out light within a specific wavelength range.

[0043] For example, such as Figure 1 As shown, the shell of the water storage tank 1 of this utility model is transparent and made of light-filtering material. The shell can filter out light in a specific wavelength range that is conducive to photosynthesis by algae, thereby inhibiting algae growth.

[0044] Preferably, the shell of the water storage tank 1 of this utility model contains bactericidal components.

[0045] For example, the shell of the water storage tank 1 of this utility model contains silver ions or zinc oxide, which can effectively kill bacteria and other microorganisms in the water in the water storage tank 1.

[0046] Preferably, the specific wavelength range of this invention is 400nm to 675nm.

[0047] In other words, the shell of the water tank 1 can filter out light with wavelengths ranging from 400nm to 675nm. Algae use photosynthetic pigments to perform photosynthesis, thereby synthesizing organic matter for growth and reproduction. Different photosynthetic pigments of algae have different absorption peaks. Therefore, by filtering out light with wavelengths of these absorption peaks from the shell, the photosynthesis of algae can be greatly reduced.

[0048] For example, the main photosynthetic pigments of algae include chlorophyll, carotenoids, and phycobilichromes, and their absorption peaks are as follows: Chlorophyll absorption band: blue or blue-green 450-475nm, red 630-675nm; Carotenoid absorption band: 400-550nm; Phycobilichrome absorption band: blue-green, green, yellow, and orange-yellow light 500-650nm. The above wavelengths cover 400-675nm, while the visible light wavelength range is 390-780nm. Therefore, the shell filters out light with wavelengths between 400-675nm, which can greatly reduce the photosynthesis of algae, thereby inhibiting the growth of algae and killing them, without affecting the user's ability to see the water level in the water storage tank 1.

[0049] In the second aspect, such as Figure 2 and Figure 3 As shown, this utility model also provides a water purification device, which includes the aforementioned water storage tank 1.

[0050] For example, such as Figure 2 and Figure 3 As shown, the water storage tank 1 of this utility model is installed on the side wall of the outer shell 2 of the water purification equipment, and the side wall of the water storage tank 1 and the side wall of the outer shell 2 are in the same plane. This arrangement makes the appearance of the water purification equipment more beautiful.

[0051] Preferably, such as Figures 1 to 3 As shown, the bottom of the water storage tank 1 of this utility model is provided with a water inlet pipe 11 extending in a vertical direction. The outer shell 2 of the water purification equipment is provided with a mounting platform 21 for installing the water storage tank 1. The mounting platform 21 is provided with an interface 211 corresponding to the water inlet pipe 11, and the water inlet pipe 11 is inserted into the interface 211.

[0052] For example, such as Figures 1 to 3As shown, the mounting platform 21 of this utility model is arranged horizontally and located on one side of the outer shell 2. The top of the mounting platform 21 is lower than the top of the outer shell 2. After the water tank 1 is installed on the mounting platform 21, it can form an integral whole with the side wall and top wall of the outer shell 2, thereby improving the aesthetics of the water purification equipment. The bottom of the water tank 1 is provided with two spaced-apart water inlet pipes 11 extending downwards. The platform 21 is provided with two interfaces 211 corresponding to the two water inlet pipes 11. The two water inlet pipes 11 can be inserted into the corresponding interfaces 211 respectively. That is to say, the bottom wall of the water tank 1 is attached to the platform 21, and one side wall of the water tank 1 is attached to the side wall of the outer shell 2.

[0053] It should be noted that when the water purification equipment does not have a filter element, the water inlet of the water storage tank 1 can be directly connected to the water outlet of the water purification equipment. When the water purification equipment has a filter element, one of the two water inlets of the water storage tank 1 is connected to the raw water inlet of the filter element, and the other is connected to the concentrated water outlet of the filter element.

[0054] Preferably, such as Figure 1 and Figure 3 As shown, the outer shell 2 and the water storage tank 1 of this utility model are respectively provided with a first positioning guide structure and a second positioning guide structure that cooperate with each other. The first positioning guide structure cooperates with the second positioning guide structure to make the water inlet pipe 11 on the water storage tank 1 smoothly inserted into the interface 211 on the mounting platform 21.

[0055] In other words, by cooperating with the first positioning guide structure and the second positioning guide structure, the water storage tank 1 can be installed onto the outer shell 2 of the water purification equipment more easily and smoothly, and the water inlet pipe 11 can be inserted into the interface 211.

[0056] It should be noted that this utility model does not limit the structural form of the first positioning guide structure and the second positioning guide structure. For example, those skilled in the art can set the first positioning guide structure and the second positioning guide structure as matching guide ribs and guide grooves, or they can set the first positioning guide structure and the second positioning guide structure as matching guide rails and guide wheels, etc. Such adjustments and changes to the specific structural forms of the first positioning guide structure and the second positioning guide structure do not deviate from the principle and scope of this utility model, and should all be limited to the protection scope of this utility model.

[0057] Preferably, such as Figure 1 and Figure 3 As shown, the first positioning guide structure of this utility model is a positioning guide rib 22 provided on the side wall of the outer shell 2, which extends in the vertical direction. The second positioning guide structure is a positioning guide groove 12 provided on the side wall of the water storage tank 1, which extends in the vertical direction. The positioning guide rib 22 and the positioning guide groove 12 are adapted to each other.

[0058] For example, such as Figure 1 and Figure 3 As shown, the outer shell 2 of this utility model is provided with a positioning guide rib 22 arranged in a vertical direction on the side wall. The positioning guide rib 22 extends to the platform of the mounting platform 21. The side wall of the water storage tank 1 that is in contact with the side wall of the outer shell 2 is provided with a positioning guide groove 12. During the installation of the water storage tank 1, the positioning guide rib 22 can be inserted into the positioning guide groove 12 and move along the guide groove 12.

[0059] Preferably, such as Figure 1 and Figure 3 As shown, the top of the positioning guide rib 22 of this utility model is provided with a card plate 221 that has a gap with the outer shell 2 and is arranged in the vertical direction. The positioning guide groove 12 is provided with a slot 121 that communicates with the positioning guide groove 12 at the position corresponding to the card plate 221. When the water tank 1 is installed on the outer shell 2, the card plate 221 can be locked in the slot 121.

[0060] For example, such as Figure 1 and Figure 3 As shown, the top of the positioning guide rib 22 of this utility model is provided with a vertically upward extending clamping plate 221. The thickness of the clamping plate 221 is less than the thickness of the positioning guide rib 22. There is a gap between the clamping plate 221 and the side wall of the outer shell 2. The top of the positioning guide groove 12 is provided with a clamping groove 121 that communicates with the positioning guide groove 12. When the water tank 1 is installed, the positioning guide rib 22 moves along the positioning guide groove 12. When the bottom wall of the water tank 1 is in contact with the table surface of the mounting platform 21, the clamping plate 221 is just locked in the clamping groove 121, thereby securing the water tank 1 to the outer shell 2 and increasing the stability of the installation of the water tank 1.

[0061] Preferably, such as Figure 1 As shown, the width of the positioning guide groove 12 of this utility model gradually increases along the direction close to the bottom of the water storage tank 1.

[0062] For example, such as Figure 1 As shown, the width of the positioning guide groove 12 of this utility model gradually increases from top to bottom. The positioning guide rib 22 is correspondingly set with the positioning guide groove 12, and the positioning guide rib 22 also gradually increases from top to bottom. Therefore, when the water storage tank 1 is installed, the positioning guide rib 22 can be inserted into the positioning guide groove 12 more conveniently and accurately, which facilitates the installation of the water storage tank 1.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
