The air pump 20 includes an air outlet 21 and a gas outlet 22 along the thickness direction (such as Figure 3a The pump housing 22 extends in the X direction, and the air outlet 21 corresponds to the first through hole 111 of the connecting piece 102.

[0097] For example, the connecting piece 102 is cylindrical, the accommodating space 12 is hollow cylindrical, the pump housing 22 of the air pump 20 is a cylindrical structure, and the side surfaces of the pump housing 22 of the air pump 20 are all located in the accommodating space 12. Figure 3bAs shown in FIG. 1 , when the air pump 20 has not yet been installed in the accommodating space 12 , the middle portion 1023 of the connecting sheet 102 serves as the annular side wall of the accommodating space 12 .

[0098] Continue to refer Figure 3a to Figure 3c The inflatable paddle board 1 of the present embodiment also includes a locking member 19. Figure 3a As shown in the figure, the locking piece 19 is connected to the air outlet 21 of the air pump 20. Since the first through hole 111 corresponds to the air outlet 21 of the air pump 20, the hollow locking piece 19 passes through the first through hole 111 and is sealed and connected with the first through hole 111, so that the air outlet 21 of the air pump 20 is connected to the inflation chamber 11, and the connecting piece 102 is limited to the pump housing 22 of the air pump 20.

[0099] Continue to refer Figure 3c The locking member 19 of the embodiment of the present application includes a first end 1901 , a second end 1902 , a middle portion 1903 and an air passage 191 .

[0100] Specifically, Figure 3c As shown, the air passage 191 is disposed in the locking member 19 and extends along a first direction (eg Figure 3c The first end 1901 of the locking member 19 and the second end 1902 of the locking member 19 are connected to each other along the first direction (as shown in the Y direction) to connect the first end 1901 of the locking member 19 and the second end 1902 of the locking member 19. Figure 3c The first end 1901 of the locking member 19 is received in the air outlet 21 and is sealed with the air outlet 21 of the air pump 20. The middle portion 1903 of the locking member 19 passes through the first through hole 111 of the connecting piece 102, so that the second end 1902 of the locking member 19 is located in the inflatable air chamber 11 and is connected to the connecting piece 102 at the outer peripheral edge of the first through hole 111 (see Figure 3b ) is sealed and connected. For example, Figure 3a As shown, the first direction (such as Figure 3a Y direction) and thickness direction (as shown in Figure 3a Furthermore, when the air pump 20 of the embodiment of the present application inflates the air chamber 11, the air flow fluid can directly enter the air chamber 11 from the air outlet 21 of the air pump 20 through the air passage 191 at the shortest distance (i.e., the locking member 19) through the first through hole 111.

[0101] For example, reference Figure 3a, a brushed cloth 101 is provided in the inflatable air chamber 11 between the first wall 13 and the second wall 14, and the brushed cloth 101 can help the paddle board body 10 maintain the stability of the inflatable air chamber 11 during the movement after inflation. In addition, one or more sealing layers are provided on the outside of the brushed cloth 101, which can prevent the gas in the inflatable air chamber 11 from overflowing, thereby improving the safety performance of the inflatable paddle board. The inflatable paddle board 1 provided in the embodiment of the present application has the air pump 20 disposed in the accommodating space 12, and is sealed and connected to the paddle board body 10 through the connecting piece 102 and the locking piece 19, so that the air outlet 21 of the air pump 20 is connected to the inflatable air chamber 11 through the locking piece 19. Furthermore, the air pump 20 of the embodiment of the present application can directly inflate the inside of the inflatable air chamber 11, which simplifies the connection structure between the paddle board body 10 and the built-in air pump 20, reduces the production cost of the inflatable paddle board, improves its sealing performance, and has a simple structure and is easy to operate.

[0102] Furthermore, since the first through hole 111 corresponds to the air outlet 21 of the air pump 20, the embodiment of the present application seals and connects the locking piece 19 through the first through hole 111 and the connecting piece 102, so that the locking piece 19 can compress the connecting piece 102 wrapped around the outer peripheral edge of the air outlet 21, thereby limiting the connecting piece 102 to the air pump 20, avoiding air leakage between the air outlet 21 and the inflatable air chamber 11, and further improving the airtightness of the connection between the inflatable paddle board 1 and the built-in air pump 20, as well as the connection strength of the connection structure between the inflatable paddle board 1 and the built-in air pump 20.

[0103] When the paddle board body 10 is not inflated, the distance between the first wall 13 and the second wall 14 is not increased by the compression of the inflatable air chamber 11. If the fitting height between the middle portion 1023 of the connecting piece 102 and the side surface of the pump housing 22 is too high, it will make it difficult to connect the first end portion 1021 of the connecting piece 102 with the first wall 13, so that the process of fixing the air pump 20 in the accommodating space 12 will be more complicated, which is not conducive to improving work efficiency.

[0104] For this reason, Figure 3a As shown in FIG. 1 , the middle portion 1023 of the connecting piece 102 of the embodiment of the present application is sealed and connected to the side of the pump housing 22 at a fitting height h1. Figure 3a The range of h1 height is the air pump height (such as Figure 3a The height of the connecting piece 102 (as shown in the figure) is one-half to two-thirds of the height h2. Figure 3a The middle portion 1023 of the portion (shown as the height h1) is sealed and connected to the side of the pump housing 22, for example, by adhesive sealing. On the one hand, the connection strength requirement between the air pump 20 and the connecting piece 102 is met; on the other hand, the connection process between the air pump 20 and the connecting piece 102 is simplified, the working efficiency is improved, and the production cost of the inflatable paddle board 1 is reduced.

[0105] Continue to refer Figure 3a and Figure 1 The inflatable paddle board 1 further includes a first reinforcement member 40. Exemplarily, the first reinforcement member 40 is an annular sheet structure extending along the circumferential direction C of the opening of the accommodation space 12.

[0120] For example, Figure 4b and Figure 4c As shown, the locking member 19 includes a hollow locking bolt, and the middle portion 1903 of the locking member 19 includes an external thread.

[0123] refer to Figure 5a to Figure 5c , Figure 5a The overall structure diagram of the air pump 20 according to the embodiment of the present application is shown. Figure 5b A cross-sectional schematic diagram of an air pump 20 according to an embodiment of the present application is shown. Figure 5c Another cross-sectional schematic diagram of the air pump 20 according to an embodiment of the present application is shown. Figure 5b The inflating air flow path of the air pump 20 in the inflating state is specifically shown. Figure 5c The deflation air flow path of the air pump 20 in the deflation state is specifically shown.

[0124] Specifically, Figure 5a , Figure 5b and Figure 5c As shown, the upper end of the pump housing 22 of the air pump 20 is provided with an air inlet 221, and an air inlet valve 2201 is installed at a position corresponding to the air inlet 221. The overall structure of the air inlet valve 2201 has not been Figure 5bThe specific structure is similar to that of the deflation valve 2202 described below. The inlet valve 2201 includes a valve stem 2210, a valve cover 2211 and an elastic body 2212. The valve stem 2210 is installed at the position of the air inlet 221 and the elastic body 2212 is installed on the valve stem 2210. The valve cover 2211 is connected to the valve stem 2210. The valve cover 2211 can seal or open the air inlet 221. The air inlet 221, the internal space of the pump housing 22, the inflatable cylinder 26 and the air outlet 21 form an inflatable air flow channel in the air pump 20 for inflating the inflatable air chamber 11. Since the first through hole 111 is connected to the inflatable air chamber 11, the air pump 20 of the embodiment of the present application can directly inflate the inflatable air chamber 11, simplifying the connection structure of the built-in air pump 20 of the inflatable paddle board 1, reducing the production cost of the inflatable paddle board 1, improving its sealing performance, and having a simple structure and easy operation.

[0125] The air pump 20 includes an air filling assembly, a circuit board 200 is installed in the pump housing 22 of the air pump 20, a key switch 2001 for starting the air filling assembly is installed on the circuit board 200, and the position of the key switch 2001 corresponds to the position of the valve stem 2210 of the air inlet valve 2201. The air filling assembly includes a motor 25, an air filling cylinder 26, and a piston 27. The air outlet 21 is arranged at one end of the air filling cylinder 26, and the piston 27 is adapted to be installed in the air filling cylinder 26. The piston 27 is provided with an air suction hole 28 and a one-way valve plate 29 is installed. The one-way valve plate 29 can be used to cover the air suction hole 28. A transmission mechanism for driving the piston 27 to move back and forth is connected between the piston 27 and the motor 25. The transmission mechanism includes a rotating shaft 30, a driving gear 31, a driven gear 32, a connecting plate 33, and a connecting rod 34. The rotating shaft 30 is rotatably mounted in the pump housing 22 of the air pump 20. The driven gear 32 and the connecting plate 33 are both mounted on the rotating shaft 30. The driving gear 3 is mounted on the output shaft of the motor 25. The driving gear 31 and the driven gear 32 are meshed for transmission. The connecting rod 34 is connected to the piston 27. A connecting groove 35 is provided at one end of the connecting rod 34. A connecting pin 36 is installed on the connecting plate 33. The connecting pin 36 is inserted in the connecting groove 35. The connecting pin 36 rotates with the connecting plate 33 to push the connecting rod 34 and the piston 27 to reciprocate together. A partition 37 is provided at the end of the inflator 26. A one-way valve plate 38 is connected to the partition 37. A plurality of through holes 39 are provided on the partition 37. The one-way valve plate 38 can open or cover the through holes 39.

[0126] The air pump 20 is built into the inflatable paddle board 1 for use. When the inflatable air chamber 11 needs to be inflated, the inflatable valve cover 223 is opened, and the valve stem 2210 of the air inlet valve 2201 is pressed downward. The valve stem 2210 will drive the valve cover 2211 to contact the key switch 2001 to start the inflatable assembly, thereby inflating the inflatable air chamber 11 through the inflatable air flow channel, which is labor-saving and convenient, and the inflatable speed is fast. After the inflation is completed, the valve stem 2210 of the air inlet valve 2201 is pressed again to restore it to its original state and the key switch 2001 is disconnected to close the inflatable assembly to seal the inflatable air flow channel, and the inflatable valve cover 223 is closed to seal the air inlet 221.

[0127] In addition to the function of inflating the inflatable air chamber 11 of the inflatable paddle board 1, the air pump 20 of the present application can also help deflate the inflatable air chamber 11 of the inflatable paddle board 1. Figure 5a and Figure 5c The air pump 20 shown in the figure has an air release port 222 disposed at the upper end of the pump housing 22 of the air pump 20, and an air release valve 2202 is installed at a position corresponding to the air release port 222. An exhaust hole 23 is disposed at the bottom of the pump housing 22 of the air pump 20, and the exhaust hole 23 is communicated with the inflatable air chamber 11. The exhaust hole 23, the exhaust pipe 24 and the air release port 222 form an air release air flow channel in the air pump 20, which is used to discharge the gas in the inflatable air chamber 11. The air release valve 2202 includes a valve stem 2210, a valve cover 2211 and an elastic body 2212, the valve stem 2210 is connected to the air release port 222, the valve cover 2211 is connected to one end of the valve stem 2210, the elastic body 2212 is installed on the valve stem 2210, and the valve cover 2211 can seal and cover or open the air release port 222. Exemplarily, the elastic body 2212 in the air inlet valve 2201 and the air release valve 2202 is a spring. When the inflatable air chamber 11 needs to be deflated, the deflation valve cover 2211 is opened, and the valve stem 2210 is pressed to open the deflation air flow channel, and the air in the inflatable air chamber 11 can be discharged outward through the deflation air flow channel, which is convenient to operate. After deflation is completed, the deflation valve cover is closed to seal the deflation port 222.

[0128] It should be noted that the embodiment of the present application does not impose any specific restrictions on the surface covering materials of the first wall 13 and the second wall 14, and other fabric-containing, high-strength materials may also be used.

[0129] The embodiment of the present application does not impose any specific restrictions 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. Preferably, the first wall of the paddle board body, the second wall of the paddle board body, the side wall of the paddle board body, the various reinforcements, the connecting sheet, the air pump, and the spacer can be connected by adhesive, for example, Figures 3a to 3c and Figure 8 In the figure, the thicker black lines are glue used for gluing.

[0130] The embodiment of the present application does not impose any specific limitation on the connection method between the above-mentioned connecting piece and the pump housing 22 . For example, the middle portion 1023 of the connecting piece 102 above the fitting height h1 may be sealedly connected to the side of the pump housing 22 .

[0131] The embodiment of the present application does not impose any specific limitation on the structure of the locking member 19 , as long as the air outlet 21 and the first through hole 111 are connected and the connecting piece 102 is compressed to avoid air leakage.

[0132] The embodiment of the present application does not impose any specific restrictions on the structure and material of the above-mentioned first reinforcement 40, second reinforcement 41, third reinforcement 42, fourth reinforcement 43, fifth reinforcement 44, sixth reinforcement 45 and side wall reinforcement 46, as long as the sealing performance and connection strength of the connection can be met.

[0133] In addition, the embodiment of the present application does not specifically limit the number of the first reinforcement 40, the second reinforcement 41, the third reinforcement 42, the fourth reinforcement 43, the fifth reinforcement 44, the sixth reinforcement 45 and the side wall reinforcement 46. For example, only the first reinforcement 40 and the second reinforcement 41 may be provided, or only the first reinforcement 40, the second reinforcement 41 and the third reinforcement 42 may be provided. As long as the reinforcement includes the first reinforcement 40, the second reinforcement 41, the third reinforcement 42, the fourth reinforcement 43, the fifth reinforcement 44, the sixth reinforcement 45 and the side wall reinforcement 46, they all fall within the protection scope of the present application.

[0134] The embodiment of the present application does not impose any specific restrictions on the structure of the air pump 20 . As long as the air pump 20 can be built into the inflatable paddle board 1 and can inflate the paddle board body 10 , it falls within the protection scope of the present application.

[0135] The following embodiments of the present application will be combined with the attached Figures 1 to 8 The process of inflating the paddle board 1 is described by way of example.

[0136] First, holes (i.e., accommodation space 12) are dug in the upper and lower layers of the wire drawing cloth 101 of the inflatable paddle board 1 (i.e., the first wall 13 and the second wall 14 of the paddle board body 10), and the size of the accommodation space 12 is within -1 cm to 4 cm of the specification of the air pump 20. Take a PVC soft mesh material (i.e., connecting piece 102) with a width of 9 cm to 22 cm and a thickness of 0.4 mm to 1.5 mm, and first stick one side (i.e., the first end 1021 of the connecting piece 102) to the hole (i.e., accommodation space 12) on the front side (i.e., the first wall 13) of the wire drawing cloth 101, with a bonding width of 1 cm to 3 cm to form a top seal. The other side (i.e., the second end 1022 of the connecting piece 102) is connected to the edge of the hole on the bottom surface (i.e., the second wall 14) of the wire drawing cloth 101 by heat sealing or gluing, with a connection width of 1 cm to 2 cm to form a bottom seal.

[0137] Next, a piece of soft PVC mesh material is glued or heat-sealed on the outer arc edge of the paddle board wire drawing cloth 101 as a sealing layer (i.e., the side wall 15), and then a layer of soft PVC mesh material is heat-sealed or glued on the side wall 15 as a reinforcement layer (side wall reinforcement 46), the side wall reinforcement 46 covers the outer surface of the side of the side wall 15 away from the inflatable air chamber 11, and the width of the side wall reinforcement 46 is 0.5 cm to 3 cm wider than the side wall 15. Preferably, before the air pump 20 is installed in the accommodating space 12, the side wall 15 is first connected to the surrounding edges of the first wall 13 and the second wall 14 of the paddle board body 10, so as to avoid that after the air pump 20 is installed in the accommodating space 12, the surrounding edges of the first wall 13 and the second wall 14 of the paddle board body 10 are not easy to align, thereby causing inconvenience to the connection of the side wall 15 with the surrounding edges of the first wall 13 and the second wall 14 of the paddle board body 10.

[0138] Part of the pump housing 22 side wall of the air pump 20 is attached to the above-mentioned connecting piece 102, and an annular PVC soft mesh material (i.e., the fifth reinforcement 44) is attached to the outer side of the connecting piece 102, and holes (i.e., the second through hole 441 and the first through hole 111) are opened at the positions corresponding to the air outlet 21 of the air pump 20 on the fifth reinforcement 44 and the connecting piece 102, respectively, and the locking bolt (i.e., the locking member 19) is passed through the first through hole 111 from the outer side of the second through hole 441 and screwed into the air outlet 21 of the air pump 20, so that the first through hole 111 and the air outlet 21 are fluidically connected, and the fifth reinforcement 44 and the connecting piece 102 are pressed to prevent air leakage. In addition, a piece of annular PVC soft mesh material (i.e., the sixth reinforcement 45) is taken and attached to the lower side of the connection between the air pump 20 and the connecting piece 102.

[0139] Finally, the paddle board body 10 is inflated, and the pump housing 22 and the upper surface of the brushed cloth 101 (i.e., the first wall 13) are connected with an annular PVC soft mesh material (i.e., the first reinforcement member 40), and the width exceeding the accommodation space 12 is 2 cm to 6 cm, forming the first reinforcement layer (i.e., the first reinforcement member 40). The back is also connected in the same way, and the pump housing 22 and the lower surface of the brushed cloth 101 (i.e., the second wall 14) are connected with a circular PVC soft mesh material (i.e., the third reinforcement member 42), and the width exceeding the accommodation space 12 is 2 cm to 6 cm, forming the third reinforcement layer (i.e., the third reinforcement member 42). A layer of annular mesh sheet (i.e., the second reinforcement member 41) is covered on the first reinforcement layer (i.e., the first reinforcement member 40), and the width exceeding the accommodation space 12 is 2 cm to 10 cm, forming the second reinforcement layer (i.e., the second reinforcement member 41). Furthermore, a circular mesh sheet (ie, the fourth reinforcement member 43) is covered on the third reinforcement layer (ie, the third reinforcement member 42), with the width exceeding the accommodating space 12 by 2 cm to 10 cm, to form a fourth reinforcement layer (ie, the fourth reinforcement member 43).

[0140] Preferably, the first reinforcement 40 , the second reinforcement 41 , the third reinforcement 42 and the fourth reinforcement 43 are all arranged at corresponding positions when the inflatable paddle board 1 is inflated.

[0141] The specific sequence is: after the inflatable paddle board 1 equipped with the air pump 20 is inflated, the first reinforcement 40 is set between the air pump 20 and the first wall 13 by means of glue, and the first reinforcement 40 is tightly attached to and connected to the upper surface of the air pump 20 and the first wall 13; similarly, the third reinforcement 42 is set between the air pump 20 and the second wall 14 by means of glue, and the third reinforcement 42 is tightly attached to and connected to the lower surface of the air pump 20 and the second wall 14.

[0142] Then the inflatable paddle board 1 is deflated. When the inflatable paddle board 1 is completely deflated, the first reinforcement 40 and the third reinforcement 42 are retracted, resulting in a circle of bulges on the surface of the first reinforcement 40 at the joint between the air pump 20 and the paddle board body 10, and a circle of bulges on the surface of the third reinforcement 42 at the joint between the air pump 20 and the paddle board body 10. Holes are punched at the bulges on the surfaces of the first reinforcement 40 and the third reinforcement 42 to release the gas between the connecting sheet 102 and the pump housing 22, so that the surfaces of the first reinforcement 40 and the third reinforcement 42 are flat. Then the holes are sealed, for example, glue can be dripped at the holes of the first reinforcement 40 and the third reinforcement 42 to seal, or other methods can be used to seal.

[0143] Inflate the inflatable paddle board 1 again. When the inflatable paddle board 1 is inflated, set the second reinforcement 41 between the air pump 20 and the first wall 13 by gluing or welding. The second reinforcement 41 is tightly attached to and connected to the upper surface of the air pump 20 and the first wall 13, and the second reinforcement 41 covers the first reinforcement 40. Similarly, when the inflatable paddle board 1 is inflated, set the fourth reinforcement 43 between the air pump 20 and the second wall 14 by gluing or welding. The fourth reinforcement 43 is tightly attached to and connected to the lower surface of the air pump 20 and the second wall 14, and the fourth reinforcement 43 covers the third reinforcement 42.

[0144] The first reinforcement 40, the second reinforcement 41, the third reinforcement 42 and the fourth reinforcement 43 are all arranged at the corresponding positions as described above when the inflatable paddle board 1 is inflated, so as to reserve a certain stretching space for the first reinforcement 40, the second reinforcement 41, the third reinforcement 42 and the fourth reinforcement 43, which can greatly reduce the force on each reinforcement at the connection position, thereby preventing each reinforcement from being debonded or torn at the connection position.

[0145] In contrast, when the inflatable paddle board 1 is in a deflated state, the connecting piece 102, the first wall 13, and the second wall 14 are not fully stretched, and at the opening of the accommodating space 12 (the joint between the air pump 20 and the paddle board body 10), there is no gap between the connecting piece 102 and the pump housing 22. At this time, if the first reinforcement 40, the second reinforcement 41, the third reinforcement 42, and the fourth reinforcement 43 are set at corresponding positions, when the inflatable paddle board 1 is inflated, the connecting piece 102, the first wall 13, and the second wall 14 are fully stretched, for example, Figure 3a As shown, at the opening of the accommodating space 12, a certain degree of gap is stretched between the connecting piece 102 and the pump housing 22, so that the first reinforcement 40, the second reinforcement 41, the third reinforcement 42 and the fourth reinforcement 43 are stretched accordingly, thereby increasing the stress on each reinforcement at the connection position, causing each reinforcement to be more easily debonded or torn at the connection position.

[0146] Moreover, reference Figure 6a to Figure 6b , the present application also provides a process for preparing a paddle board 2 with a transparent window.

[0147] For example, reference Figure 6a Combined with Figure 2 , a through hole 201 is dug in the front of the wire drawing cloth 101 of the paddle board 2, and the upper and lower surfaces (i.e., the first wall 13 and the second wall 14 of the paddle board body 10) are aligned with the hanging wires, and the size of the through hole 201 on the first wall 13 is allowed to have a deviation of less than 2 cm. The shortest distance between the edge of the through hole 201 and the arc edge of the paddle board body 10 is more than 10 cm. It should be noted that the shape of the through hole 201 is not limited.

[0148] A 5 cm to 16 cm wide soft PVC mesh material is glued or heat-sealed at the head and tail to form a ring, and is heat-sealed or glued to the first wall 13 and the second wall 14 along the edge of the through hole 201 to form a sealing layer (i.e., the through hole side wall 202) of the through hole 201. The outer arc edge of the entire paddle board body 10 is sealed with a 5 cm to 16 cm soft PVC mesh material (i.e., the side wall 15) by heat-sealing or gluing to form an inflatable air chamber 11.

[0149] Inflate the paddle board 2, and after inflation, cover the lower edge of the through hole side wall 202 with a PVC soft mesh material with a thickness of 0.4 mm to 0.9 mm and a width of 2 cm to 5 cm to form a reinforcement layer for the lower seam of the through hole side wall 202, and the annular sealing piece of the through hole 201 is glued or heat-sealed with a 2 cm to 6 cm reinforcement layer at the head and tail joints. Figure 6bAfter inflation, the upper edge of the through-hole side wall 202 is covered with a PVC soft mesh material with a thickness of 0.4 mm to 0.9 mm and a width of 2 cm to 5 cm. Velcro or thorny fasteners are sewn or heat-sealed on the PVC soft mesh material to form the first fixing piece 203 at the seam of the through-hole side wall 202, and at the same time are used to fix the cover 204.

[0150] The bottom surface of the through hole 201 is covered with a transparent plastic sheet (i.e., window 205) by gluing, for example, a transparent PVC film, the size of which is 2-5 cm wider than the intersection of the through hole 201 and the second wall 14 after inflation. Then, soft PVC or mesh material is glued to the edge of the window 205 for reinforcement. The cover 204 follows the shape of the through hole 201, and the back of the cover 204 is sewn with Velcro thorns / fleece along the edge to form a second fixing member 206, which is used in conjunction with the Velcro around the through hole 201 (i.e., the first fixing member 203).

[0151] Continue to refer Figure 6a A buckle 207 is provided on the back of the cover 204, and is buckled to fix the cover 204 after it is rolled up. For example, elastic ropes 208 are fixed around the through hole 201. The paddle board 2 with a transparent window can provide a function of storing items while increasing the fun of observing underwater, and the cover 204 can also simply prevent water from flowing into the window 205.

[0152] It should be noted that the embodiment of the present application does not impose any specific restrictions on the number of inflatable air chambers 11. Figure 2 As shown in FIG. 1 , the side wall 15 and the first wall 13 and the second wall 14 together define a complete inflatable air chamber 11; but not limited to this, refer to Figures 7 and 8 In some other possible embodiments, the paddle board body 10 further includes a thickness direction of the inflatable paddle board 1 (such as Figure 8 The diaphragm 16 extends in the X direction, and the diaphragm 16 includes a two-way valve 161.

[0153] Specifically, Figure 7 As shown, the spacer 16 is arranged in the inflatable air chamber 11, and the spacer 16 is sealed and connected to the inner side of the first wall 13 and the inner side of the second wall 14, so as to define the inflatable air chamber 11 into a first sub-air chamber 17 and a second sub-air chamber 18. Among them, the accommodating space 12 is formed within the range of the first sub-air chamber 17, and the locking member 19 is connected to the first sub-air chamber 17 and the air outlet 21 of the air pump 20.

[0154] Exemplarily, the upper end 1601 of the partition 16 along the thickness direction X is sealed and connected to the side of the first wall 13 facing the inflatable chamber 11, and the lower end 1602 of the partition 16 is sealed and connected to the side of the second wall 14 facing the inflatable chamber 11 to form a circular second air dividing chamber 18, and the first air dividing chamber 17 is arranged around the outside of the second air dividing chamber 18.

[0155] like Figure 8 As shown, the two-way valve 161 enables the first air chamber 17 and the second air chamber 18 to communicate with each other, so that the first air chamber 17 and the second air chamber 18 in the paddle board body 10 can be independent of each other, that is, when the air pressure in the first air chamber 17 decreases, the air pressure in the second air chamber 18 can remain stable; when the first air chamber 17 is inflated, gas will also flow into the second air chamber 18. The second air chamber 18 also includes an air valve (not shown in the figure), which can connect the second air chamber 18 with the outside world for deflation or inflating.

[0156] It should be noted that the embodiment of the present application does not impose any specific restrictions on the structure of the partition 16 and the first and second air chambers 17 and 18, as long as they can separate the inflatable air chamber 11 into two independent air chambers.

[0157] In addition, the present embodiment does not impose any specific restrictions on the spacer 16. Figure 7 and Figure 8 As shown in the figure, the spacer 16 divides the inflatable air chamber 11 into two independent air chambers, namely the first sub-air chamber 17 and the second sub-air chamber 18; but not limited to this, the spacer 16 can also be configured to divide the inflatable air chamber 11 into multiple independent air chambers.

[0158] So far, the present application satisfactorily describes the structure of an inflatable paddle board 1. These embodiments all enable the built-in air pump 20 of the inflatable paddle board 1 to directly inflate the inside of the inflatable air chamber 11, simplifying the connection structure of the built-in air pump 20 of the inflatable paddle board 1, reducing the production cost of the inflatable paddle board, and improving its sealing performance and connection strength.
