[0001] This utility model relates to the field of water heater technology, and in particular to a water storage tank and an outdoor water heater that can prevent deformation. Background Technology

[0002] As people's living standards improve, outdoor storage water heaters are favored by outdoor enthusiasts because they can provide a continuous and stable supply of hot water.

[0003] Currently, the water tanks of outdoor storage water heaters have good sealing performance. When a water pump is used to draw water from the tank, the continuous pumping process will gradually reduce the water volume inside the tank. The pressure inside and outside the tank cannot be effectively balanced, which causes the tank to be subjected to continuous atmospheric pressure. Its outer shell will gradually be compressed and deformed, affecting the user's subsequent use. Utility Model Content

[0004] This utility model provides a water storage tank and outdoor water heater that can prevent deformation, thus preventing the water storage tank from deforming due to water pumping and ensuring normal use by the user.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0029] 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.

[0030] 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.

[0031] 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.

[0032] An embodiment of this utility model provides a water storage tank that can prevent deformation, such as... Figure 1-5 As shown, the system includes a tank 100, the inner cavity of which is used to hold water. A vent 110 is provided at the top of the tank 100, allowing the internal cavity of the tank 100 to communicate with the outside, thus maintaining pressure balance between the inside and outside of the tank 100. A one-way valve assembly is provided within the vent 110, comprising an outer cylinder 210, a seal 220, and a limiting assembly 230. The outer cylinder 210 can be fixed within the vent 110. A raised ring 211 is provided on the inner wall of the outer cylinder 210, encircling the inner wall of the outer cylinder 210. A flow-through hole is formed on the inner side of the raised ring 211, effectively reducing the local inner diameter of the outer cylinder 210. This allows the seal 220 to close or open the flow-through hole by movement. The convex ring 211 can be integrally formed with the outer cylinder 210, or it can be fixed on the inner wall of the outer cylinder 210.

[0033] The seal 220 can slide relative to the outer cylinder 210 along the axial direction of the outer cylinder 210, thus allowing the seal 220 to move freely upwards or downwards. The seal 220 includes a sealing disc 221 located below the convex ring 211, and a limiting assembly 230 connected to the outer cylinder 210 and located below the sealing disc 221. The sealing disc 221 can move upwards to abut against the convex ring 211 to close the flow hole, preventing water in the tank 100 from flowing out through the flow hole. Under its own weight, the sealing disc 221 can move downwards away from the convex ring 211 and abut against the limiting assembly 230, which blocks the seal 220, preventing it from falling out from the inside of the outer cylinder 210.

[0034] Because the sealing disc 221 in this embodiment can move downward away from the convex ring 211 and abut against the limiting component 230 under its own weight, the flow hole can be opened and the inner cavity of the tank 100 can be connected with the external environment. When the water pump is pumping water, there is no pressure difference between the inside and outside of the tank 100, which can prevent the water storage tank from deforming due to pumping and ensure normal use by the user.

[0035] In addition, when the tank 100 tilts or experiences other abnormal situations, the sealing disc can move upward under the action of water flow to abut against the protruding ring 211, thereby sealing the flow hole and preventing water from flowing out of the tank 100. When the tank 100 does not tilt or experience other abnormal situations, since the vent 110 is located at the top of the tank 100, water inside the tank 100 will not flow out through the vent 110 on its own.

[0036] In some embodiments, such as Figure 2-5 As shown, the limiting component 230 includes a limiting seat 231, which is provided with a lower guide hole 232. The axial direction of the lower guide hole 232 is parallel to the axial direction of the outer cylinder 210. The sealing component 220 also includes a guide rod 222 connected to the sealing disc 221. The lower end of the guide rod 222 is inserted into the lower guide hole 232 and can slide along the lower guide hole 232.

[0037] The sliding engagement between the guide rod 222 and the lower guide hole 232 guides the seal 220, guiding it to move axially along the outer cylinder 210. Simultaneously, under its own weight, the sealing disc 221 moves downwards away from the convex ring 211 and abuts against the limiting seat 231, which restricts the seal 220 from falling further downwards. Therefore, in this embodiment, the limiting seat 231 not only restricts the seal 220 from falling but also guides it to move axially along the outer cylinder 210, achieving multiple functions with a single component and simplifying the structural configuration.

[0038] In this embodiment, the limiting seat 231 can abut against the bottom surface of the sealing disc 221. The sealing disc 221 and the guide rod 222 can be integrally formed, which is convenient for manufacturing and also strengthens the connection between them. The sealing disc 221 and the guide rod 222 can be coaxially arranged, which makes it easy to determine the center of the sealing disc 221 to effectively seal the flow hole.

[0039] Furthermore, the one-way valve assembly also includes a connecting cylinder 240, which is detachably fixed to the lower end of the outer cylinder 210 and connected to the outer cylinder 210. Therefore, external gas can pass sequentially through the outer cylinder 210 and the connecting cylinder 240 before entering the inner cavity of the tank 100. A limiting seat 231 is disposed on the inner side of the connecting cylinder 240 and connected to the connecting cylinder 240.

[0040] Since the connecting cylinder 240 is detachably fixed to the lower end of the outer cylinder 210, the sealing element 220 can be placed inside the outer cylinder 210 first, and then the connecting cylinder 240 can be fixed to the lower end of the outer cylinder 210. This structure facilitates the overall assembly.

[0041] The connecting cylinder 240 can be detachably fixed to the lower end of the outer cylinder 210 through various methods such as snap-fit ​​connection and threaded connection.

[0042] Furthermore, the inner side of the connecting cylinder 240 is provided with a plurality of lower connecting strips 233, the two ends of which are connected to the inner wall of the connecting cylinder 240 and the limiting seat 231, respectively.

[0043] In this embodiment, the lower connecting strip 233 is used to fix the limiting seat 231. At the same time, the lower connecting strip 233 will not block the connecting cylinder 240, and gas can flow between adjacent lower connecting strips 233 to ensure the balance of internal and external pressure of the tank 100.

[0044] In some embodiments, such as Figure 2-5 As shown, a guide seat 251 is fixed inside the flow hole. The guide seat 251 is provided with an upper guide hole 252, the axis of which is parallel to the axis of the outer cylinder 210. The guide rod 222 passes through the sealing disc 221, and the upper end of the guide rod 222 is inserted into the upper guide hole 252 and can slide along the upper guide hole 252.

[0045] The sliding fit between the guide rod 222 and the upper guide hole 252 can further guide the seal 220, enhance the guiding effect of the seal 220, prevent the seal 220 from tilting relative to the outer cylinder 210, and ensure that it can close or open the flow hole.

[0046] Furthermore, multiple upper connecting strips 253 are provided on the inner side of the flow passage, and the two ends of the upper connecting strips 253 are connected to the inner wall of the flow passage and the guide seat 251, respectively.

[0047] In this embodiment, the guide seat 251 is fixed by the upper connecting strip 253. At the same time, the upper connecting strip 253 will not block the outer cylinder 210, and gas can flow between adjacent upper connecting strips 253 to ensure the balance of internal and external pressure of the tank 100.

[0048] In some embodiments, such as Figure 3 and Figure 5 As shown, a sealing gasket 223 is provided on the surface of the sealing disc 221, and the sealing gasket 223 is placed between the sealing disc 221 and the convex ring 211. The sealing gasket 223 can effectively seal the gap between the sealing disc 221 and the convex ring 211, thereby improving the sealing performance.

[0049] The sealing gasket 223 can be disposed on the circumferential surface of the sealing disc 221, which can be inserted into the flow hole, with the sealing gasket 223 placed between the sealing disc 221 and the inner wall of the flow hole; or, the sealing gasket 223 can be disposed on the top surface of the sealing disc 221, which can be close to the bottom surface of the convex ring 211, with the sealing gasket 223 placed between the lower surface of the sealing disc 221 and the convex ring 211.

[0050] In some embodiments, such as Figure 3-5 As shown, the outer peripheral wall of the outer cylinder 210 is provided with an annular groove 212, which can surround the outer peripheral wall of the outer cylinder 210. A sealing ring 260 is embedded in the annular groove 212, and the sealing ring 260 abuts against the inner wall of the vent hole 110.

[0051] The sealing ring enhances the seal between the outer cylinder 210 and the inner wall of the vent 110, preventing water inside the tank 100 from easily leaking out through the gap between the outer cylinder 210 and the inner wall of the vent 110. The annular groove 212 positions the sealing ring 260, restricting its movement relative to the outer cylinder 210 and keeping it embedded in the annular groove 212.

[0052] In some embodiments, such as Figure 1 , Figure 2 and Figure 6 As shown, a handle groove 120 is provided on the top of the can 100, and a handle 130 is fixed in the handle groove 120. Users can grasp the handle 130 to lift the entire can 100, making it convenient for users to move the can 100. At the same time, since the handle 130 is located in the handle groove 120, the handle 130 does not protrude from the top of the can 100, making the top surface of the can 100 relatively flat, which is convenient for stacking the cans 100.

[0053] The vent 110 is connected to the handle groove 120, and the handle 130 is located above the vent 110. The handle 130 can block the vent 110, so that impurities such as leaves cannot easily enter the interior of the can 100 through the vent 110.

[0054] An embodiment of this utility model provides an outdoor water heater, such as... Figure 2 and Figure 7 As shown, it includes a host 300 and a water storage tank that can prevent deformation according to any of the above embodiments. For a detailed description of the water storage tank that can prevent deformation, please refer to the above embodiments, which will not be repeated here.

[0055] The main unit 300 is fixed to the bottom of the tank 100. The main unit 300 includes a water pump and a water pipe. The bottom of the tank 100 is provided with a water outlet 140. The two ends of the water pump are connected to the water outlet and the water pump respectively. When the water pump is working, it can pump the water in the tank 100 into the main unit for heating to produce hot water.
