In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. It will be understood that when an element is referred to as being "connected" to or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements can be present. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0043] It should be noted that the directions in the embodiments of the present utility model are shown in the drawings, and if a certain posture changes, the directional indications also change accordingly.

[0044] This invention proposes a floating platform that primarily utilizes a water spray device to propel rainwater outwards, creating a water flow to achieve a spraying function. This function is similar to the effect of a water gun, enhancing the usability of the floating platform.

[0045] In detail, the floating platform created by this invention can be a non-powered floating platform or a powered floating platform.

[0046] like Figure 1 As shown in the figure, this is a schematic diagram illustrating the structural principle of the water board. Specifically, the water board created by this invention includes a board body 10 and a water spraying device 20. The board body 10 is used to support the board and float on the water surface. The water spraying device 20 is located at the board body 10 and is used to spray water to the outside. That is, the water spraying device 20 realizes the function of spraying water, achieving the effect of a water gun.

[0047] In detail, in one specific embodiment, such as Figure 2 As shown, the board body 10 has a roughly triangular layout when viewed from above, with a smaller lateral dimension at the front and a larger lateral dimension at the rear. This shape design helps reduce water resistance at the front, while the larger rear end facilitates increased buoyancy.

[0048] Figure 2 As shown, the front and rear ends of the board body 10 each form a handle 102 on both sides for the swimmer to grip. Each handle 102 forms a cutout 107 with the side of the board body 10. This allows the swimmer's fingers to pass through the cutout 107 to enclose the handle 102 for gripping, improving stability and convenience. Both ends of the handle 102 are connected to the side of the board body 10, forming a closed opening in the lateral direction of the cutout 107. Furthermore, to improve swimmer comfort, in this embodiment, the upper surface of the board body 10 is higher than the upper surface of the handle 102 in the thickness direction. This allows for better arm support for some swimmers when gripping the handle 102, with their arms resting more comfortably on the upper surface of the rear end of the board body 10.

[0049] In one specific embodiment, the water board is a powered water board, that is, the water board also includes a power unit 30, which is located at the body 10 of the water board to drive the body 10 of the water board to move along the water surface.

[0050] like Figure 3 As shown, the platform body 10 has a recessed bottom shell 108. The bottom shell 108 is located in the middle and rear part of the entire platform body 10.

[0051] like Figure 4As shown, the bottom shell 108 is formed with an assembly cavity 103 arranged sunken along the deck body 10, and a first channel 104 and a second channel 105 arranged separately on both sides of the assembly cavity 103 for water drainage. The front ends of the first channel 104 and the second channel 105 are communicated to form a water inlet portion 106, and the tail ends are respectively extended to the tail of the deck body 10 and communicated to the outside; the water inlet portion 106 is achieved by a water inlet hole 1081 arranged at the front end of the bottom of the deck body 10. The first channel 104 and the second channel 105 converge at the front end to form the water inlet portion 106. The first channel 104 and the second channel 105 are arranged expanding from front to back, that is, the first channel 104 is arranged from front to back to the left, and the second channel 105 is arranged from front to back to the right. Among them, the first channel 104 and the second channel 105 are arranged towards the rear at the tail of the bottom shell 108. Specifically, the water outlet of the first channel 104 and the water outlet of the second channel 105 are arranged towards the front-rear axial direction of the deck body 10.

[0052] Among them, as shown, Figure 4 The power device 30 is configured to have a driving motor 301 and a propeller 302, the output end of the driving motor 301 is in transmission connection with the propeller 302 to drive the propeller 302 to rotate. The driving motor 301 is assembled at the assembly cavity 103, and the propeller 302 is located at the water inlet portion 106; when the driving motor 301 works, it drives the propeller 302 to rotate to discharge the water entering the water inlet portion 106 rearward through the first channel 104 and the second channel 105. Specifically, in the embodiment, the water inlet hole 1081 is located in front of the water inlet portion 106. In use of the deck, the water flow will enter the water inlet portion 106 along the water inlet hole 1081, and the propeller 302 rotates under the action of the driving motor 301, and when rotating, the water flow at the water inlet portion 106 is discharged rearward into the first channel 104 and the second channel 105, and finally discharged at the tail of the deck body 10, so as to realize driving the deck to move forward. Specifically, the driving motor 301 is connected to the electric control board 2022, and the electric control board 2022 is further connected with a second control button 303, which is arranged at one of the handle portions 102 and located at the lower end of the handle portion 102, which is conducive to controlling the work of the driving motor 301, and further realizing the motion control of the electric deck.

[0053] In another embodiment, the second control button 303 can be a gear shifting button switch. In the process of continuously pressing, different speeds are realized by adjusting the number of gears to drive the driving motor 301 to generate different rotating speeds, so as to realize motion control at different speeds. Of course, the second control button 303 is realized by using the existing waterproof type button, which is the prior art, and therefore will not be described in detail in the embodiment, but it cannot be considered that the present scheme is not fully disclosed.

[0054] Importantly, the water board of the present solution comprises a water spraying device 20 which is assembled at the board body 10. In use, the water spraying device 20 can spray water to realize the water gun function.

[0055] In detail, the water spraying device 20 is configured to have a water pump 201, a control group 202 and a water outlet 203. The water pump 201 has a water inlet end and a water outlet end, the water inlet end is communicated with the outside for sucking water from the outside; the control group 202 is arranged at the board body 10 and is electrically connected with the water pump 201 for controlling the water pump 201 to work; the water outlet 203 is arranged at the board body 10 and is communicated with the water outlet end of the water pump 201 to spray the water delivered by the water pump 201 to the outside.

[0056] In detail, the water pump 201 is used to pump water into the water pump 201 through the water inlet end and then discharge the water to the water outlet 203 through the water outlet end to realize the water spraying function.

[0057] In one embodiment, the water pump 201 is a submersible pump which can be exposed outside. When the water board is used on water, the submersible pump is wrapped by water flow, at this time, the water inlet end of the submersible pump is immersed in water and can very conveniently pump water flow to realize water spraying. In this embodiment, since the submersible pump is used, it is not necessary to additionally set an independent water inlet pipe, it is only necessary to ensure that the submersible pump is immersed in water during use to realize the water pumping function and thus realize the water spraying of the water gun. Of course, the present solution is not limited to this, other suitable pumps can also be used to realize water pumping. For example, the pump can be arranged inside the board body 10 and then a pipe is externally arranged to connect the water inlet end of the pump to the outside of the board body 10, especially to the bottom of the board body 10, which is more conducive to pumping water in the environment.

[0058] In detail, as shown in Figure 4 The water pump 201 is arranged at the tail of the bottom shell 108 and is assembled at the bottom as much as possible, which is conducive to the water board placed in water to better pump water.

[0059] In this embodiment, the control group 202 can be used to control the working of the water pump 201 and provide power. In order to protect the control group 202, the control group 202 can be sealed inside the board body 10.

[0060] The water outlet 203 can be a water guide pipe, one end of which is communicated with the water outlet end of the water pump 201, and the other end is arranged at a required position of the board body 10 and communicated with the outside. In this way, the water pumped by the water pump 201 will be guided outwards along the water guide pipe. Specifically, the water guide pipe is arranged inside the board body 10. In detail, a groove can be arranged in the board body 10, and the water guide pipe is placed at the corresponding groove to achieve the placement of the water guide pipe.

[0061] It should be noted that the water outlet of the water outlet 203 can be arranged at different positions according to different use requirements. Preferably, the water outlet of the water outlet 203 is located at the front end of the board body 10. That is, in the embodiment, the water outlet of the water guide pipe is located at the front end of the board body 10. The design is conducive to better controlling the direction of the water flow of the water outlet when the swimmer uses it.

[0062] In another specific embodiment, the water outlet of the water outlet 203 can be multiple, such as at least three. The at least three water outlets can be arranged at different positions as required. For example, when including three water outlets, one corresponding water outlet can be arranged at the front end and left and right sides of the board body 10. Three water outlets can also be arranged side by side at the front end of the board body 10. Of course, as shown in the figure, in one specific embodiment, the water outlet 203 includes a main water guide pipe 01 and three branch water guide pipes 02. One end of the main water guide pipe 01 is communicated with the water outlet end of the water pump 201, and the other end is communicated with the three branch water guide pipes 02 through a flow divider. In this way, the water pumped by the water pump 201 flows through the main water guide pipe 01 and is then divided into the three branch water guide pipes 02, and the water outlets of the three branch water guide pipes 02 are then sprayed outwards. Figure 7

[0063] In another embodiment, the water outlet of the water outlet 203 is arranged along the upper front direction at a set angle with the surface of the board body 10. Specifically, as shown in the figure, an inclined flow channel 109 is arranged in the board body 10, and the flow channel 109 is arranged upward. In particular, the flow channel 109 is arranged at the front end of the board body 10, so that the water flow of the water outlet 203 will flow into the flow channel 109 and be sprayed outwards, and the water flow is sprayed forward and upward. The included angle between the flow channel 109 and the horizontal plane is any angle between 10° and 80°, which can be designed according to actual requirements. Preferably, the included angle is 45°. In this way, the sprayed water can be in an inclined state at the beginning, and the sprayed water can be sprayed to a certain height. Of course, the water outlet 203 can be a water guide pipe, and the water outlet end of the water guide pipe is arranged at the flow channel 109, and the orientation of the flow channel 109 limits the water outlet angle of the water guide pipe. Figure 8

[0064] ​​Of course, the water outlet angle of the water outlet device 203 in this embodiment is set at the time of product delivery. That is, the water outlet angle can be set at different angles during production, but once produced, the corresponding water outlet angle is fixed.

[0065] However, in other embodiments, the angle of the water outlet device 203 can be defined as adjustable. That is, after production, adjustment is made during actual use.

[0066] Specifically, referring to Figure 9 The water outlet device 203 includes a pipeline 2031 and an angle adjuster 2032, one end of the pipeline 2031 is connected to the water outlet end of the water pump 201, and the other end is located at the angle adjuster and is connected to the outside to realize angle adjustment. In this embodiment, the angle adjuster 2032 is movably arranged with the board body 10, and when the angle adjuster 2032 is adjusted, the water outlet angle can be adjusted. In one specific embodiment, as shown in Figure 9 The board body 10 forms a clamping space 1011, and the angle adjuster 2032 is arranged at the clamping space 1011, and the two ends of the angle adjuster 2032 are pivotally connected to the side walls 1012 on both sides of the clamping space 1011. The water outlet end of the pipeline 2031 is arranged at the front end of the angle adjuster 2032. In this way, when the rotation angle of the angle adjuster 2032 is manually adjusted, the elevation angle of the water outlet of the corresponding pipeline 2031 can be changed. In this way, the water outlet angle of the water outlet device 203 can be adjusted. Of course, in order to better maintain the state of the angle adjuster 2032 after adjusting the angle, a rubber sleeve is arranged between the pivot shaft of the angle adjuster 2032 and the side wall 1012 to realize interference fit. In this way, during rotation, the corresponding angle can be better maintained. It should be noted that in this embodiment, the angle adjuster 2032 is a solid structure, and the two ends are pivotally connected to the side walls 1012. As shown in Figure 10 In one embodiment, the angle adjuster 2032 is provided with a corresponding through hole 20321, and the water outlet end of the pipeline 2031 is sleeved in the through hole 20321. Of course, as shown in Figure 11 A water flow passage 20322 can be arranged at the angle adjuster 2032, and the output end of the pipeline 2031 is connected to the connection part 20323 at the tail of the water flow passage 20322 to realize communication.

[0067] In detail, as shown in Figure 4 and Figure 6As shown in the figure, the control group 202 includes a control button 2021, an electric control board 2022 and a power supply 2023; the electric control board 2022 is electrically connected to the power supply 2023 and the water pump 201, and the control button 2021 is in control connection with the electric control board 2022 to realize the operation control of the control button 2021 to control the working of the water pump 201.

[0068] It should be noted that the electric control board 2022 in this embodiment is a conventional prior art, which can realize the working control of the water pump 201. It should be clear that the control of the pump is a conventional technology, which will not be specifically described in this scheme, but it cannot be considered that the disclosure of this scheme is insufficient.

[0069] The power supply 2023 can be a lithium battery, especially a rechargeable lithium battery. The lithium battery can supply power to the water pump 201 and the electric control board 2022.

[0070] As shown in the figure, Figure 4 The tummy board body 10 is configured to have a sealed cavity 101, and the electric control board and the power supply are arranged in the sealed cavity 101. That is, the electric control board 2022 and the power supply 2023 are protected by the sealed cavity 101. In detail, in this embodiment, the sealed cavity 101 is located inside the tummy board body 10. As shown in the figure, Figure 12 The tummy board body 10 further includes a face plate 1013 and an intermediate plate 1014. During assembly, the intermediate plate 1014 is clamped and fixed by the bottom shell 108 and the face plate 1013 to form the tummy board body 10. The sealed cavity 101 is formed between the intermediate plate 1014 and the face plate 1013. When the intermediate plate 1014 and the face plate 1013 are closed, the sealed cavity 101 is sealed.

[0071] In this embodiment, in order to facilitate the operation of the water pump 201, the tummy board body 10 has a handle part 102 for the operator to hold, and the control button 2021 is arranged at the handle part 102. As shown in the figure, Figure 3As shown, the control button 2021 is located at the bottom of the handle part 102 and exposed downward. In this way, when in use, the swimmer holds the handle part 102 and presses the control button 2021 with the finger to spray water when needed. It should be noted that the control button 2021 in the embodiment is a conventional sealed mechanical button which is connected to the control board 2022 through an electric circuit. The spraying operation can be realized by pressing the cover control button 2021. The control button 2021 and the second control button 303 are respectively arranged at one of the handle parts 102. That is, the control button 2021 and the second control button 303 are arranged on the two sides of the board body 10, which is beneficial for separate control.

[0072] In another embodiment, the control button 2021 can be a gear adjusting button switch. The multi-gear adjustment is realized by continuous pressing to control the water sprayer 201 to generate different flow rates of spraying water.

[0073] In summary, the above technical scheme can realize the spraying function of the water board, increase the use function of the board, and meet the use requirements of the user.

[0074] The technical features of the above embodiments can be combined arbitrarily.
