[0002] The water flying device is a recently emerging water sports equipment. It can be driven by its own electric motor in waveless waters, giving users a surfing experience, while also avoiding waves and depth to eliminate safety hazards to users.

[0003] In order to raise the height of the skateboard body relative to the water surface and keep the skateboard body away from the water surface, existing water flying devices usually add front and rear wings, so as to raise the height of the skateboard body relative to the water surface through the water pressure effect of the front and rear wings.

[0004] However, the water flying device of this structure is expensive, complex in structure, and requires many installation procedures. Summary of the invention

[0005] The invention solves the problem that the water flying device has high cost, complex structure and many installation procedures.

[0006] To solve the above problems, an embodiment of the present invention provides a water flying device, comprising: a skateboard body; a propulsion device, connected under the skateboard body, for providing the power required for the skateboard body to slide; a propeller shroud, arranged on one side of the propulsion device; wherein, for the cross-section of the propeller shroud, its length in the horizontal direction is greater than its length in the vertical direction, and the cross-section is perpendicular to the axis of the propulsion device.

[0007] Compared with the prior art, the embodiments of the present invention have the following beneficial effects: by providing a propeller guard, impurities such as water plants can be prevented from being drawn into the propeller to cause propeller failure; thereby improving the safety of user use and the service life of the water flying device; at the same time, a cross-section of the propeller guard is provided, and its length in the horizontal direction is greater than its length in the vertical direction, and the cross-section is perpendicular to the axis of the propulsion device; the water pressure area in the horizontal direction perpendicular to the axis of the propeller guard is increased; the inclination angle of the propeller guard can be changed by adjusting the center of gravity of the user on the skateboard body, thereby achieving the purpose of changing the travel direction of the water flying device; the overall structure is simpler, and there is no need to add front and rear wings. The propeller guard can be used to achieve the purpose of pressurizing water and raising the height of the skateboard body relative to the water surface to improve the balance performance, and the cost is relatively lower, which is suitable for large-scale production and promotion.

[0008] In an optional embodiment, the outer surface of the propeller shroud on a side away from the propulsion device is polygonal.

[0009] It can be understood that the polygonal shape of the propeller shroud increases the contact area with the water surface, thereby increasing the water pressure area, making it easier to change the direction of travel of the water flight device by changing the inclination angle of the propeller shroud.

[0010] In an optional embodiment, the propulsion device includes: a motor body connected to the connecting rod and one end of which is connected to the propeller shroud; a propeller disposed in the propeller shroud and connected to the motor body.

[0011] It can be understood that by setting up a motor to provide rotational force to the propeller, the water flying device is pushed forward under the drive of the propeller; the propeller is placed in a propeller guard to protect the propeller and prevent impurities such as water plants from being drawn in and causing propeller failure.

[0012] Furthermore, the surface of the motor body is an arc surface, and the end where the motor body is connected to the propeller shroud is connected through the arc surface; the arc surface of the motor body surface is an inner arc surface, and the arc surface at the end where the motor body is connected to the propeller shroud is an outer arc surface. By setting the inner and outer arc surfaces, the surface between the motor body and the propeller shroud is streamlined during the forward movement of the water flight device, which greatly reduces the water flow resistance.

[0013] In an optional embodiment, the propeller shroud is a symmetrical or asymmetrical pattern.

[0014] It can be understood that when the propeller guard is set in a symmetrical shape, it is convenient to improve the balance of the water flying device when it moves on the water surface and is less likely to roll over.

[0015] In an optional embodiment, the outer surface of the propeller shroud on a side away from the propulsion device is rhombus-shaped; wherein the inner angle of the rhombus in the horizontal direction is smaller than the inner angle in the vertical direction.

[0016] It can be understood that a diamond-shaped propeller shroud is set, and the inner angle in the horizontal direction is smaller than the inner angle in the vertical direction, so that the resistance on both sides of the propeller shroud in the horizontal direction is relatively smaller, which is beneficial to reducing the resistance caused by setting up the propeller shroud and maintaining the travel speed of the water flying device.

[0017] In an optional embodiment, the propeller guard includes: an upper swing covering the upper end of the propeller; and a lower swing correspondingly connected to the upper swing and covering the lower end of the propeller; wherein the upper swing and the lower swing are symmetrically or asymmetrically arranged.

[0018] It can be understood that the propeller shroud formed by the upper and lower swing settings increases the water pressure area of ​​the propeller shroud, and the travel direction of the water flying device is adjusted by changing the inclination of the lower swing in contact with the water surface.

[0019] In an optional embodiment, the outer surface of the propeller shroud on a side away from the propulsion device is elliptical, semi-elliptical or semi-circular.

[0020] It can be understood that setting the outer surface of the propeller shroud on the side away from the propulsion device to be elliptical, semi-elliptical or semi-circular can increase the contact area between the propeller shroud and the water surface in the horizontal direction, thereby improving the stability of the water flying device; at the same time, it can also be used for direction adjustment by changing the user's center of gravity on the skateboard body and adjusting the inclination of the propeller shroud to adjust the direction.

[0021] In an optional embodiment, it also includes: a connecting rod, one end of which is connected to the lower end of the skateboard body; a direction adjustment device, which is connected to the other end of the connecting rod; wherein the propulsion device is connected to the connecting rod and a gap is provided between the propulsion device and the direction adjustment device.

[0022] It can be understood that the skateboard body is connected to the direction adjustment device through a connecting rod to adjust the direction of travel; at the same time, a propulsion device is arranged on the connecting rod, and a gap is provided between the propulsion device and the direction adjustment device to avoid affecting the direction adjustment of the direction adjustment device.

[0023] In an optional embodiment, the direction adjustment device includes: a cross bar, one end of which is connected to the end of the connecting rod and is parallel to the length direction of the skateboard body; and a balance wing, the middle of which is connected to the other end of the cross bar.

[0024] It can be understood that by arranging a balance wing on a cross bar parallel to the skateboard body, the user can adjust the direction of travel by adjusting the center of gravity on the skateboard body; at the same time, the middle part of the balance wing is connected to the other end of the cross bar, which can improve the accuracy of adjusting the direction of the balance wing and improve the balancing ability of the water flying device during travel, making it less likely to roll over.

[0025] Furthermore, the side of the balance wing close to the forward direction of the water flying device is a cambered surface, so as to reduce water flow resistance.

[0026] Furthermore, the balance wing is connected to a side of the crossbar close to the skateboard body, which can increase the water pressure effect of the direction adjustment device, improve the balancing ability, and make the water flying device more stable during the forward movement.

[0027] In an optional embodiment, the skateboard body includes: a mounting portion, which is disposed at the lower end of the skateboard body; wherein the connecting rod is connected to the skateboard body via the mounting portion.

[0028] It can be understood that the connection between the skateboard body and the connecting rod is made tighter.

[0029] Furthermore, a sealing ring is provided at the connection between the mounting portion and the connecting rod to increase the sealing performance and prevent water from entering the interior of the skateboard body.

[0030] In an optional embodiment, the skateboard body further includes: a power supply installation position, which is disposed in the skateboard body; and a power supply, which is disposed in the power supply installation position and is connected to the propulsion device.

[0031] It can be understood that the power supply and the power supply mounting position are provided to facilitate the placement of the power supply; at the same time, the power supply mounting position is set inside the skateboard body to prevent the power supply from contacting with water flow and causing damage.

[0032] In an optional embodiment, the connecting rod is hollow and has a built-in power cord, and the power source and the propulsion device are connected via the power cord.

[0033] It can be understood that the connecting rod is set to be hollow to facilitate the built-in power cord to connect the power supply and the propulsion device.

[0034] The present invention has the following beneficial effects:

[0035] 1) The overall structure of the present invention is simple, and the purpose of adjusting the direction of travel can be achieved without the need to add additional front and rear wings. The installation steps are reduced, the installation is more convenient, the cost is relatively lower, and it is suitable for large-scale production and promotion. 2) The propeller guard provided can prevent impurities such as water plants from being drawn into the propeller and causing propeller failure; thereby improving the safety of user use and the service life of the water flying device; at the same time, the shape and structure of the propeller guard increases the water pressure area of ​​the propeller guard and improves the lifting ability of the propeller guard, so that the water flying device can further increase the height of the skateboard body relative to the water surface during surfing, allowing the user to maintain balance; at the same time, the inclination angle of the propeller guard can be changed by adjusting the center of gravity of the user on the skateboard body, thereby achieving the purpose of changing the direction of travel of the water flying device; and it has good balance during travel on the water and is not easy to tip over;

DETAILED DESCRIPTION

[0045] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0046] See also Figure 1 An embodiment of the present invention provides a water flying device 100, including: a skateboard body 110, a propulsion device 140 and a propeller shroud 150.

[0047] Specifically, the propulsion device 140 is connected below the skateboard body 110 to provide the power required for the skateboard body 110 to slide; a propeller shroud 150 is provided on one side of the propulsion device 140; wherein, for the cross-section of the propeller shroud 150, its length in the horizontal direction is greater than its length in the vertical direction, and the cross-section is perpendicular to the axis of the propulsion device 140.

[0048] By providing the propeller guard 150, it is possible to prevent impurities such as water plants from being drawn into the propeller 142 and causing the propeller 142 to malfunction, thereby improving the safety of user use and the service life of the water flying device 100. At the same time, for the cross-section of the propeller guard 150, its length in the horizontal direction is greater than its length in the vertical direction, and the cross-section is perpendicular to the axis of the propulsion device 140. The water pressure area of ​​the propeller guard 150 in the horizontal direction perpendicular to the axis of the propulsion device 140 is increased. By adjusting the center of gravity of the user on the skateboard body 110, the inclination angle of the propeller guard 150 can be changed, thereby achieving the purpose of changing the travel direction of the water flying device 100. The overall structure is simpler and the installation is more convenient. There is no need to add front and rear wings to achieve the purpose of adjusting the travel direction. The cost is relatively lower and it is suitable for large-scale production and promotion.

[0049] For example, the surface of the propulsion device 140 is curved to reduce the resistance to the water flow and increase the travel speed.

[0050] For further information, see Figure 2 The propulsion device 140 includes: a motor body 141 connected to the connecting rod 120 and one end of which is connected to the propeller shroud 150 ; a propeller 142 disposed in the propeller shroud 150 and connected to the motor body 141 .

[0051] A motor is provided to provide rotational force to the propeller 142, so that the water flying device 100 is pushed forward under the drive of the propeller 142; the propeller 142 is arranged in a propeller guard 150 to protect the propeller 142 and prevent impurities such as water plants from being drawn in and causing the propeller 142 to malfunction.

[0052] For example, see Figure 1 and Figure 2 The surface of the motor body 141 is an arc surface 143, and the end of the motor body 141 connected to the propeller shroud 150 is connected to the propeller shroud 150 through an arc surface 144; the arc surface 143 on the surface of the motor body 141 is an inner arc surface, and the arc surface 144 at the end of the motor body 141 connected to the propeller shroud 150 is an outer arc surface. By setting the inner and outer arc surfaces, the surface between the motor body 141 and the propeller shroud 150 is streamlined during the forward movement of the water flying device 100, which greatly reduces the water flow resistance.

[0053] It should be noted that the so-called inner arc surface here refers to an arc center that is arranged close to the motor body 141; the so-called outer arc surface refers to an arc center that is arranged far away from the motor body 141.

[0054] For further information, see Figure 3 The propeller shroud 150 has a symmetrical or asymmetrical pattern.

[0055] By setting the propeller guard 150 to be a symmetrical shape, the balance of the water flying device 100 when traveling on the water surface can be improved.

[0056] Furthermore, the outer surface of the propeller shroud 150 on the side away from the propulsion device 140 is in a rhombus shape; wherein the inner angle of the rhombus in the horizontal direction is smaller than the inner angle in the vertical direction.

[0057] By providing a diamond-shaped propeller shroud 150, with the inner angle in the horizontal direction being smaller than the inner angle in the vertical direction, the resistance on both sides of the propeller shroud 150 in the horizontal direction is relatively smaller, which is beneficial to reducing the resistance brought by the propeller shroud 150 and maintaining the traveling speed of the water flying device 100.

[0058] For example, see Figure 5 The outer surface of the propeller guard 150 on the side away from the propulsion device 140 may also be triangular. By setting the triangular propeller guard 150, the structure is more stable. At the same time, the bottom surface of the triangular propeller guard 150 has a larger water pressure area, and it is easy to adjust the travel direction of the water flying device 100 by adjusting the swing angle of the propeller guard 150.

[0059] Furthermore, the outer surface of the propeller shroud 150 on the side away from the propulsion device 140 is elliptical, semi-elliptical or semi-circular.

[0060] By setting the outer surface of the propeller guard 150 on the side away from the propulsion device 140 to be elliptical, semi-elliptical or semi-circular, on the one hand, the contact area between the propeller guard 150 and the water surface in the horizontal direction can be increased, thereby raising the height of the skateboard body 110 relative to the water surface and improving the balance performance of the water flying device 100 during movement; on the other hand, it can also be used for direction adjustment by changing the user's center of gravity on the skateboard body 110 and adjusting the inclination of the propeller guard 150 to adjust the direction; at the same time, the curved outer surface can reduce water flow resistance and increase the travel speed.

[0061] For example, see Figure 6 The propeller guard 150 may also be in the shape of a plate, connected to the propeller 142, and the outer surface of the propeller guard 150 away from the propulsion device 140 is in a straight line. While increasing the water pressure area and raising the height of the slide body 110 relative to the water surface, the resistance during the travel process is reduced, and the travel speed of the water flying device 100 is increased.

[0062] For further information, see Figure 3 The propeller guard 150 includes an upper hem 151 and a lower hem 152 .

[0063] Specifically, the upper swing 151 covers the upper end of the propeller 142; the lower swing 152 is correspondingly connected to the upper swing 151 and covers the lower end of the propeller 142; wherein the upper swing 151 and the lower swing 152 are symmetrically or asymmetrically arranged.

[0064] The rhombus-shaped propeller guard 150 formed by the symmetrical arrangement of the upper hem 151 and the lower hem 152 can adjust the travel direction of the water flying device 100 by changing the inclination of the lower hem 152 in contact with the water surface; at the same time, the rhombus-shaped propeller guard 150 formed by the symmetrical arrangement of the upper hem 151 and the lower hem 152, the two side surfaces of the lower hem 152 forming a certain angle, when the direction is adjusted by changing the inclination of the propeller guard 150, during the tilting process of the lower hem 152, the angle between one of the side surfaces and the horizontal plane is reduced relative to the other side surface, thereby increasing the contact area between one of the side surfaces of the lower hem 152 and the water surface during the tilting process, so that the lower hem 152 maintains a good high water pressure area, which is conducive to raising the height of the skateboard body relative to the water surface, and improving the stability of the device during the direction adjustment process.

[0065] For further information, see Figure 1 , and also includes: a connecting rod 120, one end of which is connected to the lower end of the skateboard body 110; a direction adjustment device 130 is connected to the other end of the connecting rod 120; wherein the propulsion device 140 is connected to the connecting rod 120, and a gap is set between the propulsion device 140 and the direction adjustment device 130.

[0066] The skateboard body 110 is connected to the direction adjustment device 130 via the connecting rod 120 for adjusting the travel direction; at the same time, the propulsion device 140 is arranged on the connecting rod 120 and is spaced apart from the direction adjustment device 130 to avoid affecting the direction adjustment of the direction adjustment device 130.

[0067] For further information, see Figure 2 The direction adjustment device 130 includes: a cross bar 131, one end of which is connected to the end of the connecting rod 120 and is parallel to the length direction of the skateboard body 110; and a balance wing 132, the middle of which is connected to the other end of the cross bar 131.

[0068] By arranging a balance wing 132 on a cross bar 131 parallel to the skateboard body 110, the user can adjust the direction of travel by adjusting the center of gravity on the skateboard body 110; at the same time, the middle part of the balance wing 132 is connected to the other end of the cross bar 131, which can improve the accuracy of adjusting the direction of the balance wing 132 and improve the balancing ability of the water flying device 100 during travel, so that it is not easy to roll over.

[0069] For example, the side of the balance wing 132 close to the forward direction of the water flying device 100 is a curved surface 144, so as to reduce the water flow resistance.

[0070] Alternatively, the balance wing 132 is connected to a side of the crossbar 131 close to the skateboard body 110. The water pressure effect of the direction adjustment device 130 can be increased, the balance ability can be improved, and the water flying device 100 can be more stable during the forward movement.

[0071] For further information on water flying devices, see Figure 1 The skateboard body 110 includes: a mounting portion 112, which is disposed at the lower end of the skateboard body 110; wherein the connecting rod 120 is connected to the skateboard body 110 through the mounting portion 112. The skateboard body 110 and the connecting rod 120 are connected more tightly.

[0072] For example, a sealing ring is provided at the connection between the mounting portion 112 and the connecting rod 120 to enhance the sealing performance and prevent water from entering the interior of the skateboard body 110 .

[0073] Furthermore, the skateboard body 110 also includes: a power supply installation position 111 and a power supply (not shown in the figure).

[0074] For details, see Figure 2 The power supply installation position 111 is disposed in the skateboard body 110 ; the power supply is disposed in the power supply installation position 111 and is connected to the propulsion device 140 .

[0075] The power supply and the power supply mounting position 111 are provided to facilitate placement of the power supply; at the same time, the power supply mounting position 111 is provided inside the skateboard body 110 to prevent the power supply from contacting with water flow and causing damage.

[0076] For further information, see Figure 4 The skateboard body 110 further includes a fixing rope 113, both ends of which are fixedly connected to the upper end of the skateboard body 110; the fixing rope 113 is elastic and is used to fix the instep of the user standing on the upper end of the skateboard body 110, thereby increasing the stability of the user standing on the skateboard body 110.

[0077] Preferably, two groups of fixing ropes 113 are provided, arranged along the length direction of the skateboard body 110, so as to fix the user's feet.

[0078] Furthermore, the connecting rod 120 is hollow and has a built-in power cord, through which the power supply and the propulsion device 140 are connected.

[0079] By setting the connecting rod 120 to be hollow, it is convenient to insert a power cord to connect the power source and the propulsion device 140.

[0080] Although the present invention is disclosed as above, the present invention is not limited thereto.
