The present invention relates to a water sports apparatus, and more particularly to an inflatable paddle board.
An inflatable paddle board is a common water sports apparatus. Compared with a hard paddle board, the inflatable paddle board has the advantages of being foldable when deflated and facilitating transportation and storage, and thus is more and more popular among water sports enthusiasts. The air pressure is very important for the inflatable paddle board. During the inflation process, the air pressure in the inflatable paddle board must be strictly set as required to reach a preset value. If the preset value is not reached, that is, the inflatable paddle board is not inflated sufficiently, the hardness of the inflatable paddle board is insufficient, which will affects the user experience; if the air pressure exceeds the preset value, that is, overinflation occurs, the inflatable paddle board will deform or even burst, which affects the service life of the inflatable paddle board. In addition, during the use of the inflatable paddle board, if the inflatable paddle board leaks air slowly, a user often cannot immediately detect this situation, and the user is already in danger when detecting the air leakage; or the air pressure of the inflatable paddle board is the preset value during the inflation, but after exposure to sunlight, the air pressure rises with the increase of the temperature, which makes the inflatable paddle board have a safety hazard of burst. Especially in long-distance paddling, the air pressure of the inflatable paddle board is more important.
It is convenient to solve the air pressure control problem during the inflation of the inflatable paddle board, and the user often uses an inflation device with a pressure meter when inflating the inflatable paddle board to control the pressure of the inflatable paddle board. However, the user cannot learn about the pressure of the inflatable paddle board at any time when using the inflatable paddle board, and thus the hidden danger that the user cannot detect the situation in which the inflatable paddle board leaks air or the pressure is too high cannot be avoided.
