Description

Technical Field

[0001] The present invention relates to the field of underwater boosters, and particularly to an underwater booster with built-in underwater communication. Background Art

[0002] An underwater booster, also known as a frogman booster, is one of the important assistance means for navy frogmen or diving enthusiasts to conduct shallow sea diving, and is increasingly favored by users abroad; the underwater booster provides people with a brand-new form of entertainment, which improves the range and speed of people's activities in the water. It can not only allow people to sail freely on the water surface, but also take swimmers into the underwater world for activities such as sightseeing and exploration.

[0003] After searching Chinese patents, the publication number is: CN110920840B, an underwater booster with a built-in lighting device, including a body. A main lamp is provided on the front of the body. Propulsion mechanisms are provided on both the left and right sides of the body. First inner grooves and second inner grooves are respectively formed inside the body. The first inner groove is located above the second inner groove. A telescopic mechanism and a deceleration mechanism are respectively provided inside the first inner groove, and they cooperate with each other; through the settings of the telescopic mechanism, the deceleration mechanism, the rotation mechanism, the sliding mechanism, the auxiliary lighting mechanism, the fixing mechanism, the baffle and the cleaning mechanism, the problems that when conducting underwater operations, it is inconvenient to observe the surrounding situation due to a small lighting range, and it is impossible to decelerate in time in the face of emergencies and there is a lack of protection measures are solved. To a certain extent, it gives protection and fixation to the user, improves the safety and practicability of the booster, and brings convenience to the user's use.

[0004] The existing underwater boosters cannot fold the handle. Generally, the handle of an underwater booster is fixedly installed on the surface of the underwater booster. When the underwater booster is not in use, since the handle and the underwater booster are distributed in a cross shape and the length of the handle is relatively long, a large amount of space will be occupied when storing it, and it is not convenient to carry, reducing the practicability. It is also not convenient to maintain the underwater communicator. During the use of the underwater communicator, it may be damaged and needs to be maintained. Generally, the underwater communicator is installed on the surface of the underwater booster through multiple screws. When maintaining it, a screwdriver is required to disassemble the screws in sequence, and when installing, the screws need to be installed in sequence again. The entire maintenance process is relatively cumbersome, increasing the workload and reducing the maintenance efficiency, and it is not convenient to use. To solve the above problems, we propose an underwater booster with built-in underwater communication. Summary of the Invention

[0005] The purpose of the present invention is to provide an underwater booster with built-in underwater communication, and its advantage is that it can fold the handle and is convenient for maintaining the underwater communicator.

[0006] The above technical object of the present invention is achieved by the following technical solutions: An underwater booster with built-in underwater communication includes a housing.
