Description

Technical Field

[0001] This utility model relates to the field of above-ground water tanks, and in particular to an above-ground water tank. Background Technology

[0002] Above-ground pools are recreational products for outdoor leisure. Currently, pools on the market typically include conventional frame pools and conventional sheet metal pools. However, conventional frame pools and sheet metal pools are often fixed with brackets and screws, making installation, disassembly, and storage inconvenient. Furthermore, the brackets of conventional frame pools and sheet metal pools are prone to deformation after prolonged use, posing a risk of collapse, which results in a short lifespan for these types of pools. Utility Model Content

[0003] The purpose of this invention is to solve the problems of inconvenient disassembly, assembly, and storage, and short service life of existing above-ground water tanks on the market. This invention provides an above-ground water tank that can extend the service life of the tank, is not prone to collapse or deformation, and is simple to assemble and disassemble and easy to store.

[0004] To solve the above-mentioned technical problems, the present invention discloses an above-ground water tank, comprising: an inflatable frame, including: an inner wall, including a top end and a bottom end; an outer wall, including a top end and a bottom end, and disposed opposite to the inner wall; an upper wall connected to the top ends of the inner wall and the outer wall; a lower wall connected to the bottom ends of the inner wall and the outer wall; an inflatable cavity defined by the inner wall, the outer wall, the upper wall and the lower wall; and an inner liner disposed on the inflatable frame, including: an inner sheet, including a top end and a bottom end; and a bottom sheet connected to the bottom end of the inner sheet, and together with the inner sheet defining the water tank cavity.

[0005] By adopting the above technical solution, this embodiment of the application connects the inner sheet of the liner to the bottom sheet to form a water storage cavity for storing water, thereby realizing the water storage function of the above-ground water tank. Furthermore, the liner forming the water storage cavity is disposed inside the inflatable frame. Therefore, when the inflatable frame is in an inflated state, it can serve as a supporting structure for the above-ground water tank, thus supporting the liner.

[0006] Furthermore, the above-ground water tank provided in this application embodiment uses an inflatable frame as a fixed support on the outside and an inner lining as the tank body on the inside. Compared with conventional frame water tanks and conventional sheet metal water tanks currently on the market, the above-ground water tank provided in this application embodiment is easier to assemble and disassemble. Installation can be completed by inflating and assembling, and disassembly can be completed by deflating and storing, occupying less space.

[0007] Furthermore, compared to the supports in conventional framed water tanks and conventional sheet metal water tanks currently on the market, the inflatable frame in this embodiment is more stable and less prone to deformation and collapse, which can effectively extend the service life of the above-ground water tank and reduce production and maintenance costs.

[0008] Preferably, the inflatable frame further includes: a fabric strip located between the inner wall and the outer wall, comprising: a first fabric connected to the inner wall; a second fabric connected to the outer wall; and a plurality of threads located between the first fabric and the second fabric, each of the plurality of threads comprising: a first end connected to the first fabric; and a second end connected to the second fabric.

[0009] Preferably, the top end of the inner sheet is fixed to the inner wall.

[0010] Preferably, the liner further includes: an outer sheet, including a top end and a bottom end, and disposed opposite to the inner sheet; an upper sheet, located between the outer sheet and the inner sheet, and connected to the top end of the outer sheet and the top end of the inner sheet to define an installation space; the inflatable frame is partially located within the installation space.

[0011] Using the above technical solution, the inflatable frame of this application embodiment is partially housed within the installation space, so that the outer, upper, and inner sheets of the liner can be fitted onto the inflatable frame, so that the inflatable frame and the liner together form an above-ground water tank.

[0012] Preferably, the perimeter of the outer piece is smaller than the perimeter of the outer wall but larger than the perimeter of the inner wall.

[0013] Using the above technical solution, after the inflatable frame of this application embodiment is inflated, since the perimeter of the outer piece is smaller than the perimeter of the outer wall, the outer wall is supported by the gas in the inflation cavity, thereby applying a compressive force to the outer piece located on the outside of the outer wall, so that the outer piece of the inner lining is supported, the sliding friction between the outer piece and the outer wall increases, and the movement of the outer piece is restricted to achieve the effect of fixing the outer piece, thereby connecting the inner lining and the inflatable frame together to form a ground water pool.

[0014] Preferably, it further includes: a first connector fixed to the outer piece; and a second connector fixed to the outer wall and detachably connected to the first connector.

[0015] Using the above technical solution, in this application embodiment, the first connector of the outer sheet is connected to the second connector of the outer wall so that the outer sheet and the outer wall are detachably connected, thereby allowing the inner lining to be supported by the inflatable frame.

[0016] Preferably, the number of the first connectors includes a plurality of first connectors, and the plurality of first connectors are arranged in a spaced manner around the outer piece.

[0017] Preferably, the number of the first connectors includes a plurality of second connectors, and the plurality of second connectors are provided, the plurality of second connectors being distributed at intervals around the outer wall.

[0018] Using the above technical solution, in this embodiment of the application, a plurality of first connectors provided on the outer sheet are connected one-to-one with a plurality of second connectors provided on the outer wall, so that the outer sheet is connected to the outer wall, thereby the inner lining can be fixedly supported on the inflatable frame and form a ground water pool.

[0019] Preferably, the first connector extends around the outer piece once, and the second connector extends around the outer wall once.

[0020] Using the above technical solution, in this embodiment of the application, the first connecting member surrounding the outer sheet is connected to the second connecting member surrounding the outer wall, so that the outer sheet is connected to the outer wall, thereby the inner lining can be fixedly supported on the inflatable frame and form a ground-level water pool.

[0021] Preferably, the first connector and the second connector are hook and loop fasteners or snap fasteners.

[0022] Preferably, the liner further includes an inflatable ring connected to the top of the inner sheet.

[0023] Using the above technical solution, after the inflatable frame of this application embodiment is inflated, it can support the inner lining, allowing the user to fill the water storage cavity of the inner lining with water. Furthermore, after water is filled into the water storage cavity, the inflatable ring rises due to the upward buoyancy along the height direction, allowing the water storage cavity to further accommodate water and increasing its water storage capacity.

[0059] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0060] Figures 1 to 4B An above-ground water tank 100 provided in a first exemplary embodiment of this application is shown.

[0061] like Figure 1 As shown, the above-ground water tank 100 includes an inflatable frame 110 and an inner liner 120. The inflatable frame 110 is in an inflated state. The inflatable frame 110 supports the inner liner 120 to form an above-ground water tank 100 with a stable water storage cavity 120a, in which water is stored.

[0062] like Figure 2A and Figure 2B As shown, the inflatable frame 110 includes an inner wall 111 and an outer wall 112, the inner wall 111 and the outer wall 112 being respectively along the circumference of the ground pool 100 (e.g., Figure 1 Extending in the direction shown in the middle R direction. Along the radial direction of the above-ground pool (as shown in the middle R direction). Figure 1 and Figure 2A(As shown in the X direction), the outer wall 112 surrounds the outer side of the inner wall 111, and the circumference of the outer wall 112 is greater than the circumference of the inner wall 111. Exemplarily, both the inner wall 111 and the outer wall 112 are continuous flexible sheet-like TPU / PVC polymer composite materials forming a ring.

[0063] The inflatable frame 110 also includes a top wall 113 and a bottom wall 114. The inner wall 111 includes a top end 111a and a bottom end 111b, and the outer wall 112 includes a top end 112a and a bottom end 112b. The top wall 113 and the bottom wall 114 extend circumferentially R. Radially X, the top wall 113 is sealed to the top end 111a of the inner wall 111 and the top end 112a of the outer wall 112, respectively, and covers the outer periphery edges (i.e., top ends 111a and 112a) of the upper ends of the inner wall 111 and the outer wall 112. The bottom wall 114 is sealed to the bottom end 111b of the inner wall 111 and the bottom end 112b of the outer wall 112, respectively, and covers the outer periphery edges (i.e., bottom ends 111b and 112b) of the lower ends of the inner wall 111 and the outer wall 112. Thus, the inner wall 111, outer wall 112, top wall 113 and bottom wall 114 of the inflatable frame 110 together define the inflatable cavity 115.

[0064] In other embodiments, the top end 111a of the inner wall 111 and / or the top end 112a of the outer wall 112 may not be covered by the top wall 113, that is, the top end 111a of the inner wall 111 and / or the top end 112a of the outer wall 112 are outside the inflation cavity 115; similarly, the bottom end 111b of the inner wall 111 and / or the bottom end 112b of the outer wall 112 may not be covered by the bottom wall 114, that is, the bottom end 111b of the inner wall 111 and / or the bottom end 112b of the outer wall 112 are outside the inflation cavity 115.

[0065] refer to Figure 2B and combined Figure 2A The inflatable frame 110 is made of a wire mesh 116 with a certain wire height, which is located between the inner wall 111 and the outer wall 112.

[0066] Specifically, the fabric 116 includes a first fabric 117, a second fabric 118, and a plurality of threads 119, each of the threads 119 including a first end 119a and a second end 119b. The first fabric 117 is connected to the inner wall 111, the second fabric 118 is connected to the outer wall 112, and the plurality of threads 119 are located between the first fabric 117 and the second fabric 118. Exemplarily, the first fabric 117 is adhered and fixed to the inner wall 111, and the second fabric 118 is adhered and fixed to the outer wall 112. The plurality of threads 119 are of uniform length, and both ends of each thread 119 are fixedly connected to the two fabric layers respectively. That is, the first end 119a of each thread 119 is connected to the first fabric 117, and the second end 119b is connected to the second fabric 118. After the inflatable frame 110 is inflated, the filament fabric 116 generates tension on the inner wall 111 and the outer wall 112, maintaining the stability of the inflation chamber 115.

[0067] refer to Figure 3A and Figure 3B The lining 120 includes an inner sheet 121 and a bottom sheet 122, the inner sheet 121 being circumferentially aligned with the ground-level pool 100 (e.g., ...). Figure 1 Extending in the direction shown in the middle R. For example... Figure 3B As shown, the inner sheet 121 includes a bottom end 121a. Along the height direction Z of the above-ground pool 100, the bottom sheet 122 is sealingly connected to the bottom end 121a of the inner sheet 121, and the bottom sheet 122 covers the outer periphery of the lower end of the inner sheet 121 (i.e., the bottom end 121a). Thus, as... Figure 3A As shown, the inner sheet 121 and the bottom sheet 122 of the liner 120 together define a water storage cavity 120a. The water storage cavity 120a has an opening along the height direction Z of the ground-level water tank 100 to allow a user to enter the ground-level water tank 100. For example, as... Figure 1 As shown, in this embodiment, the inflatable frame 110 is circular and the water storage cavity 120a is circular. In other embodiments, the inflatable frame 110 may also be square or elliptical, and the water storage cavity 120a may be square or elliptical, respectively.

[0068] The above-ground water tank 100 provided in this embodiment seals the inner sheet 121 and the bottom sheet 122 of the liner 120 together to form a water storage cavity 120a for storing water, thereby realizing water storage in the above-ground water tank 100. Furthermore, the inner sheet 121 and the bottom sheet 122 forming the water storage cavity 120a are disposed inside the inflatable frame 110. Therefore, when the inflatable frame 110 is in an inflated state, the inflatable frame 110 can serve as a support structure for the above-ground water tank 100, thereby supporting the liner 120. (See reference...) Figure 4A and Figure 4B The inner sheet 121 in this embodiment also includes a top end 121b. Along the height direction of the above-ground pool 100 (e.g., Figure 4A and Figure 4BAs shown in the Z-direction, the upper periphery (i.e., the top edge 121b) of the inner sheet 121 is located below the connection between the top wall 113 and the inner wall 111 of the inflatable frame 110. The top edge 121b is connected to the inner wall 111 so that the inner liner 120 is fixedly supported on the inflatable frame 110. That is, in this embodiment, the inner sheet 121 of the inner liner 120 is directly connected to the inner wall 111 of the inflatable frame 110, thereby fixing the inner liner 120 to the inflatable frame 110.

[0069] also, Figure 5A and Figure 5B An above-ground water tank 100 and a filter pump provided in a first exemplary embodiment of this application are shown.

[0070] Specifically, such as Figure 5A As shown, the inner sheet 121 of the liner 120 in this embodiment of the application further includes a first through hole 121c, and the inflatable frame 110 further includes a second through hole 111c corresponding to the first through hole 121c and a water inlet / outlet pipe 111d.

[0071] like Figure 5B As shown, the outer wall 112 and inner wall 111 of the inflatable frame 110 are respectively provided with second through holes 111c to form a channel 111e through which the inlet / outlet water pipe 111d can pass. Along the radial direction of the inflatable frame 110 (i.e., the radial direction of the above-ground water tank 100, such as...) Figure 5B (As shown in the X direction), the channel 111e passes through the inflatable frame 110. The second through holes 111c on the outer wall 112 and the inner wall 111 form the two ends of the channel 111e. The inlet / outlet water pipe 111d passes through the first through hole 121c, the second through hole 111c and the channel 111e. The inlet / outlet water pipe 111d is sealed and connected to the inner wall 111, the outer wall 112 and the inner plate 121 to connect the external filter pump 200 and the water storage chamber 120a. Thus, the filter pump 200 can circulate and filter the water in the water storage chamber 120a of the ground water tank 100.

[0072] Figures 6 to 8B An above-ground water tank 100 provided in a second exemplary embodiment of this application is shown.

[0073] Unlike the first exemplary embodiment, the liner 120 in this embodiment is fitted onto the inflatable frame 110 and does not need to be directly connected to the inflatable frame 110.

[0074] Specifically, such as Figure 6 and Figure 7 As shown, the lining 120 in this embodiment further includes an outer sheet 123 and an upper sheet 124. The outer sheet 123 includes a top end 123a and a bottom end 123b. The outer sheet 123 extends along the circumference of the ground-level pool 100 (e.g., ...). Figure 6Extending in the direction of R (as shown), surrounding the outer side of the inner piece 121, the perimeter of the outer piece 123 is greater than the perimeter of the inner piece 121. For example... Figure 8A As shown, along the radial direction X, the upper piece 124 is disposed between the outer piece 123 and the inner piece 121, and connects the top end 123a of the outer piece 123 and the top end 121b of the inner piece 121, so that the outer piece 123, the upper piece 124 and the inner piece 121 together define an installation space 120b, and the inflatable frame 110 is partially located within the installation space 120b.

[0075] Combination Figure 7 The upper end of the inflatable frame 110 is located within the installation space, and the outer sheet 123, upper sheet 124, and inner sheet 121 are fitted together on the upper end of the inflatable frame 110. When the ground water tank is in use, i.e., after the inflatable frame is inflated and the water storage cavity is filled with water, the upper sheet 124 contacts the top wall 113, the inner sheet 121 contacts the inner wall 111, and the outer sheet 123 contacts the outer wall 112, thereby allowing the liner 120 to be supported by the inflatable frame 110. Exemplarily, the upper sheet 124 is annular and has an inner periphery and an outer periphery. The inner periphery of the upper sheet 124 is connected to the top end 121b of the inner sheet 121, and the outer periphery of the upper sheet 124 is connected to the top end 123a of the outer sheet 123, so that the inner sheet 121, outer sheet 123, and upper sheet 124 of the liner 120 together form a continuous flexible sheet material in an annular shape to define the installation space 120b. For example, such as Figure 8A As shown, in this embodiment, the inner piece 121, the outer piece 123, and the upper piece 124 together form an annular structure with an arched cross-section, and the installation space 120b is an annular space with an elliptical cross-section. In other embodiments, the inner piece 121, the outer piece 123, and the upper piece 124 may also together form an annular structure with a square or circular cross-section, and the installation space 120b is correspondingly an annular space with a square or circular cross-section.

[0076] The installation process of the above-ground water tank 100 in this embodiment includes: First, inflating the inflatable frame 110 (i.e., the first inflation) so that the inflatable frame 110 has a certain amount of gas, but the gas does not completely fill the inflatable frame 110. That is, the inflatable frame 110 is in a soft state and can deform; then, the inner liner 120 is fitted onto the upper end of the inflatable frame 110 in the soft state; finally, inflating the inflatable frame 110 again (i.e., the second inflation) until the gas does not completely fill the inflatable frame 110. That is, the inflatable frame 110 is in a supported state, and the inner liner 120 can be fixed to the inflatable frame 110.

[0077] It should be noted that the perimeter of the outer piece 123 is smaller than the perimeter of the outer wall 112 but larger than the perimeter of the inner wall 111. After the inflatable frame 110 is fully inflated, because the perimeter of the outer piece 123 is smaller than the perimeter of the outer wall 112, the outer wall 112 is supported by the gas in the inflation chamber 115, thereby applying a compressive force to the outer piece 123 located outside the outer wall 112. This causes the outer piece 123 of the inner liner 120 to be supported, increasing the sliding friction between the outer piece 123 and the outer wall 112, thus restricting the movement of the outer piece 123 and achieving the effect of fixing the outer piece 123. Consequently, the inner liner 120 and the inflatable frame 110 are connected together to form the ground-level water tank 100, which is easy to assemble and disassemble, convenient to store, and has a long service life and is not easily collapsed or deformed.

[0078] Figures 9 to 10B An above-ground water tank 100 provided in the third exemplary embodiment of this application is shown.

[0079] Unlike the first exemplary embodiment, in this embodiment, the liner 120 is fitted onto the inflatable frame 110 and is directly connected to the inflatable frame 110 via connectors (e.g., the first connector 123c and the second connector 112c).

[0080] Specifically, such as Figure 9 and Figure 10A As shown, the lining 120 in this embodiment of the application also includes an outer sheet 123 and an upper sheet 124. The perimeter of the outer sheet 123 is greater than the perimeter of the outer wall 112, and the outer sheet 123 is connected to the outer wall 112 by connectors (i.e., the first connector 123c and the second connector 112c described later).

[0081] It is understood that the perimeter D1 of the outer piece 123 is not limited in this embodiment and can be selected according to the needs of the above-ground pool 100. For example, the perimeter D1 of the outer piece 123 is greater than the perimeter D2 of the outer wall 112; or, the perimeter D1 of the outer piece 123 may be less than or equal to the perimeter D2 of the outer wall 112. This embodiment will be described using the example that the perimeter D1 of the outer piece 123 is greater than the perimeter D2 of the outer wall 112.

[0082] like Figure 10A As shown, the inner liner 120 is fitted onto the upper end of the inflatable frame 110, and the perimeter D1 of the outer piece 123 is greater than the perimeter D2 of the outer wall 112. That is, when the inflatable frame 110 is fully inflated, there is no compressive force between the outer wall 112 of the inflatable frame 110 and the outer piece 123 of the inner liner 120.

[0083] like Figure 9 and Figure 10BAs shown, the outer sheet 123 includes a plurality of first connectors 123c, and the outer wall 112 includes a plurality of second connectors 112c corresponding to the first connectors 123c. The plurality of first connectors 123c and the plurality of second connectors 112c are connected one-to-one to connect the outer sheet 123 and the outer wall 112, thereby allowing the inner liner 120 to be supported by the inflatable frame 110.

[0084] For example, such as Figure 9 As shown, along the circumference of the above-ground pool 100 (e.g.) Figure 9 (As shown in the R direction), five first connectors 123c are spaced apart on the outer piece 123, and five second connectors 112c are spaced apart on the outer wall 112. The five first connectors 123c and the five second connectors 112c are connected one-to-one.

[0085] However, this application embodiment does not impose a specific limitation on the number of the first connector 123c and the second connector 112c, as long as the liner 120 and the inflatable frame 110 can be connected by the first connector 123c and the second connector 112c. For example, the number of the first connector 123c and the second connector 112c can also be 2, 3, 4, 6, 7 or more.

[0086] Furthermore, this application embodiment does not specifically limit the types of the first connector 123c and the second connector 112c. For example, such as Figure 9 As shown, the first connector 123c and the second connector 112c are snap fasteners; however, they are not limited to this, as long as the first connector 123c and the second connector 112c can be connected to each other to connect the liner 120 to the inflatable frame 110. For example, the first connector 123c and the second connector 112c can also be hook and loop fasteners or zippers.

[0087] Figure 11 An above-ground water tank 100 provided in the fourth exemplary embodiment of this application is shown.

[0088] Unlike the first exemplary embodiment, in this embodiment, the liner 120 is fitted onto the inflatable frame 110 and directly connected to the inflatable frame 110 via connectors (e.g., a first connector 123c and a second connector (not shown in the figure)). Furthermore, unlike the third exemplary embodiment, in this embodiment, the connectors are along the circumference of the above-ground pool 100 (e.g.,...). Figure 11 Extend one circle (as shown in the R direction).

[0089] Specifically, such as Figure 11As shown, the inner liner 120 is fitted onto the upper end of the inflatable frame 110. The first connector 123c extends around the circumference R of the ground pool 100, and the second connector (not shown) extends around the circumference R of the ground pool 100. The first connector 123c and the second connector (not shown) are connected to each other so that the outer sheet 123 is connected to the outer wall 112, thereby allowing the inner liner 120 to be supported by the inflatable frame 110.

[0090] For example, such as Figure 11 As shown, the first connector 123c is a hook-and-loop fastener that wraps around the entire outer piece 123, and correspondingly, the second connector (not shown) is a hook-and-loop fastener that wraps around the entire outer wall 112. Similarly, this embodiment does not specifically limit the types of the first connector 123c and the second connector, as long as they can be connected to each other to connect the liner 120 to the inflatable frame 110. For example, the first connector 123c and the second connector could also be zippers.

[0091] Figures 12 to 14 An above-ground water tank 100 provided in the fifth exemplary embodiment of this application is shown.

[0092] Unlike the first exemplary embodiment, the liner 120 in this embodiment has an inflatable ring 125 and is supported by an inflatable frame 110, and does not need to be directly connected to the inflatable frame 110.

[0093] Specifically, such as Figure 12 As shown, the inner sheet 121 in this embodiment of the application also includes an inflatable ring 125. After the inflatable frame 110 is fully inflated, it can support the inner liner 120. The inflatable ring 125 abuts against the inner wall 111, allowing the user to inject water into the water storage cavity 120a formed by the inner liner 120. Figure 13 and Figure 14 As shown, along the height direction of the above-ground pool 100 (e.g.) Figure 13 (As shown in the Z-direction), the inflatable ring 125 is located at the top end 121b of the inner sheet 121. Combined with... Figure 12 After water is injected into the water storage chamber 120a, the air ring 125 rises due to the upward buoyancy along the height direction, so that the water storage chamber 120a can further accommodate water and increase the water storage capacity of the water storage chamber 120a.

[0094] It is understood that the liner 120 in this embodiment does not need to be connected and fixed to the inflatable frame 110, making it more convenient for users. Figure 14As shown, the top end 121b of the inner sheet 121 of the liner 120 is provided with an inflatable ring 125. The inflatable ring 125 is buoyed by the water injected into the water storage chamber 120a, and together with the inner sheet 121, it is supported by the inner wall 111 of the inflatable frame 110, so that the liner 120 of this embodiment can form an above-ground water tank 100 together with the inflatable frame 110. This embodiment does not impose specific limitations on the sealing connection method between the inflatable ring 125 and the inner sheet 121. For example, the sealing connection can be achieved by high-frequency welding, adhesive bonding, or hot melting, or the inflatable ring 125 and the inner sheet 121 can be integrally formed.

[0095] Figures 15 to 17B An above-ground water tank 100 provided in the sixth exemplary embodiment of this application is shown.

[0096] Unlike the first exemplary embodiment, in this embodiment, the bottom sheet 122 of the liner 120 is directly connected to the inflatable frame 110 to form a water storage cavity 120a together with the inflatable frame 110.

[0097] Specifically, such as Figure 16A and Figure 16B As shown, in this embodiment, the bottom sheet 122 is connected to the bottom wall 114 of the inflatable frame 110, so that the bottom sheet 122 of the liner 120 and the inner wall 111 of the inflatable frame 110 together form a water storage cavity 120a. After the inflatable frame 110 is inflated, it can be supported so that the user can fill water into the water storage cavity 120a formed by the liner 120. Exemplarily, the bottom sheet 122 is connected to the radially X outer side of the bottom wall 114, that is, the bottom sheet 122 covers the bottom wall 114 of the inflatable frame 110. However, it is not limited to this, such as... Figure 17A and Figure 17B As shown, in some other possible implementations, the bottom sheet 122 of the liner 120 of this application embodiment forms a water storage cavity 120a together with the inner wall 111 of the inflatable frame 110, and the bottom sheet 122 is connected to the radial X inner side of the bottom wall 114, that is, the bottom sheet 122 is located inside the inflatable frame 110.

[0098] This application does not impose specific limitations on the shape of the inflatable frame 110. For example, as shown... Figure 6 As shown, viewed from above along the height direction Z of the ground-level pool 100, the inflatable frame 110 is circular in shape. However, it is not limited to this; for example, the shape of the inflatable frame 110 can also be other shapes such as ellipse or polygon.

[0099] The embodiments of this application do not impose specific limitations on the surface covering materials of the inner wall 111, outer wall 112, top wall 113, bottom wall 114, inner sheet 121, bottom sheet 122, outer sheet 123 and upper sheet 124. For example, it can be the TPU / PVC polymer composite material mentioned above, but it is not limited to this. It can also be other composite upper sheet materials containing fabric and with high strength.

[0100] This application does not impose specific limitations on the sealing connection method between the above-mentioned components. For example, the sealing connection can be achieved by high-frequency welding, adhesive bonding, or hot melting.

[0101] Thus, this application satisfactorily describes the structure of an above-ground water tank 100. These embodiments all enable the inflatable frame 110 of the above-ground water tank 100 to function as a support structure after inflation, supporting the inner liner 120 and together forming the above-ground water tank 100. Compared with conventional bracket water tanks and conventional sheet metal water tanks currently on the market, the above-ground water tank 100 provided by the embodiments of this application is easier to assemble and disassemble; installation can be completed by inflation and assembly, and disassembly can be completed by deflation and storage, occupying less space.

[0102] Furthermore, compared to the supports in conventional framed pools and conventional sheet metal pools currently on the market, the inflatable frame 110 in this embodiment is more stable and less prone to deformation and collapse, which can effectively extend the service life of the above-ground pool 100 and reduce production and maintenance costs.

[0103] The exemplary embodiments disclosed in this application can be replaced, combined or modified in various ways. Without departing from the essence of this application, all such variations still belong to the concept of this application and fall within the protection scope defined by the claims of this application.

[0104] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
