[0026] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0027] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0029] An embodiment of this utility model provides a water storage tank with a filter screen, such as... Figure 1-5As shown, the system includes a tank 100, a filter screen 210, a filter cover 220, and a partition 300. The tank 100 has a receiving cavity for holding water. The filter screen 210 is disposed within the receiving cavity and divides it into an upper cavity 110 and a lower cavity 120 located below the upper cavity 110. Water in the upper cavity 110 must pass through the filter screen 210 before flowing into the lower cavity 120. An outlet 101 is provided on the bottom wall of the lower cavity 120, through which water in the receiving cavity can flow out to provide the user with the required water. The filter cover 300 is shaped like a cover, located in the lower cavity 120 and covering the outlet 101. Water flowing from the upper cavity 110 into the lower cavity 120 must pass through the filter cover 300 before flowing to the outlet 101. The partition 300 is fixed inside the lower cavity 120 and is vertically arranged. The partition 300 is located inside the filter cover 300 and directly above the outlet 101. The partition 300 can be arranged radially along the outlet 101. The mesh size of the filter screen 210 is larger than that of the filter cover 220.

[0030] If air bubbles are present in the water, the filter screen 210 can break them up. Since the mesh size of the filter screen 210 is larger than that of the filter cover 220, the filter cover 220 can further break up the air bubbles. The baffle 300 acts as a divider for the water flow. When water enters the outlet from one side of the baffle 300, the other side of the baffle 300 is open, which facilitates the discharge of air bubbles. As a result, air bubbles are less likely to enter the water pump, thus preventing the water pump from running dry due to large air bubbles and ensuring normal water use for users.

[0031] Meanwhile, the filter screen 210 can filter out large impurities, while the filter cover 220 can filter out small impurities, preventing impurities from entering the water pump and clogging it, thus making the water output from the tank 100 cleaner.

[0032] In some embodiments, such as Figure 2 and Figure 3 As shown, two connecting columns 130 are provided on the bottom wall of the lower cavity 120. These two connecting columns 130 can extend vertically and are located on both sides of the outlet 101. The two ends of the baffle 300 are connected to the two connecting columns 130 respectively. The baffle 300 is fixed by the two connecting columns 130, ensuring its stability and preventing displacement under the impact of water flow. Simultaneously, this fixed structure allows the baffle 300 to maintain a essentially vertical orientation, better dividing the water flow. If air bubbles are present in the water, they can float up from the side of the baffle 300 opposite to the water inlet.

[0033] Furthermore, each of the two connecting posts 130 is provided with a connecting seat 140 on one side close to each other. The connecting seat 140 is provided with a slot, and the two ends of the partition 300 are respectively inserted into the slots of the two connecting seats 140, which facilitates the assembly of the partition 300. When necessary, the partition 300 can also be pulled out from the slots of the two connecting seats 140.

[0034] In some embodiments, such as Figure 2 and Figure 3 As shown, the filter cover 220 is fixedly connected to two connecting posts 130. Thus, the connecting posts 130 are used not only to fix the partition 300, but also to fix the filter cover 220. There is no need to set separate fixing structures for the partition 300 and the filter cover 220, which simplifies the overall installation structure and facilitates assembly.

[0035] The filter cover 220 can be fixed to the two connecting posts 130 by screws.

[0036] In some embodiments, such as Figure 2 and Figure 3 As shown, the bottom wall of the lower cavity 220 has a downwardly recessed positioning groove 121. The shape and size of the positioning groove 121 are adapted to the shape and size of the filter cover 220. The water outlet 101 is located on the bottom wall of the positioning groove 121, and the filter cover 220 is inserted into the positioning groove 121.

[0037] In this embodiment, the filter cover 220 is positioned by cooperating with the positioning groove 121, so that the filter cover 220 is not easy to move and can be kept on the outside of the water outlet 101, thus ensuring its function of breaking up air bubbles and filtering impurities.

[0038] In some embodiments, such as Figure 2 , Figure 4 and Figure 5 As shown, the height of the filter cover 220 is greater than the distance from the filter screen 210 to the bottom wall of the lower cavity 120. The filter screen 210 has an upwardly protruding protrusion 211, and the filter cover 220 is located below the protrusion 211.

[0039] In this embodiment, the filter cover 220 is taller, which provides more space for the installation of the partition 300, while the protrusion 211 can effectively avoid obstructing the filter cover 220. A certain gap can be reserved between the filter screen 210 and the filter cover 220 to allow water flow.

[0040] In some embodiments, such as Figure 2 and Figure 3 As shown, a portion of the bottom wall of the upper cavity 110 is recessed downward to form a recessed portion 111. The filter screen 210 covers the recessed portion 111, and the recessed portion 111 and the filter screen 210 enclose each other to form the lower cavity 120.

[0041] In this embodiment, the lower cavity 120 is formed by using a recess, which facilitates product manufacturing and molding. The filter screen 210 does not need to cover the entire bottom wall of the upper cavity 110, which facilitates the assembly of the filter screen 210.

[0042] Furthermore, such as Figure 3 and Figure 5 As shown, the sidewall of the recessed portion 111 may be provided with multiple buckles 112, and the periphery of the filter screen 210 may be provided with a downwardly extending flange 212. The flange 212 is provided with a slot 213 that matches the buckle 112. The buckle 112 is snapped and fixed in the slot 213. The filter screen 210 is installed by snapping and fixing, which facilitates the installation and removal of the filter screen 210.

[0043] In some embodiments, such as Figure 2 and Figure 3 As shown, a return water inlet 102 is also provided on the bottom wall of the lower cavity 120. A water temperature sensor 400 is fixed inside the lower cavity 120, and the water temperature sensor 400 is located inside the filter cover 220. The water in the tank 100 flows to the heat exchanger through the outlet 101, the heat exchanger heats the water, and the heated hot water flows back through the return water inlet 102, so that the water in the tank 100 can be circulated and heated to ensure the user's hot water needs.

[0044] The water temperature sensor 400 can detect the water temperature and send the detected temperature data to the control module. The control module then drives the display module to set limits, making it convenient for users to know the water temperature.

[0045] Furthermore, the return water inlet 102 is connected to a return water pipe 103, and the return water direction of the return water pipe 103 is parallel to the horizontal direction and away from the water temperature sensor 400. As a result, the water flowing out of the return water pipe 103 will flow in a direction away from the water temperature sensor 400, and the returned hot water can be fully mixed with the original cold water in the tank 100, making the water temperature detected by the water temperature sensor 400 more accurate and realistic.

[0046] An embodiment of this utility model provides an outdoor water heater, such as... Figure 6 As shown, the system includes a main unit 500 and a water storage tank with a filter screen, as described in any of the above embodiments. Specific details regarding the water storage tank with the filter screen can be found in the above embodiments and will not be repeated here. The main unit 500 is fixed to the bottom of the tank 100. The main unit 500 includes a water suction pipe and a water pump, with both ends of the water suction pipe connected to a water outlet and the water pump, respectively. When the water pump is operating, it can pump water from the tank 100 into the main unit 500 for heating to produce hot water.
