Description

Technical Field

[0001] The utility model belongs to the field of diving equipment, in particular to a diving respirator with double air inlets for staggered air intake. Background Art

[0002] The original meaning of diving is to go under the water with or without professional tools for underwater survey, salvage, repair and underwater engineering. Later, diving gradually developed into a leisure sport with underwater activities as the main content, so as to achieve the purpose of physical exercise and leisure and entertainment, and it is widely loved by the public.

[0003] With the development of the times, people's requirements for diving experience are also increasing; the equipment to ensure breathing during diving has been developed from scratch, and the relevant technology of diving breathing equipment is changing with each passing day to meet people's needs. Nowadays, there are many types of diving breathing equipment with various functions, which are mainly used to ensure that divers can breathe normally underwater.

[0004] Common shallow water breathing equipment mainly consists of an air intake pipe, an air pump, a controller, an air supply pipe that goes underwater, and a respirator. During use, the diver swims underwater, the controller controls the air pump to work, sucks air above the water surface through the air intake pipe, and the air pump pressurizes the air and guides it from the air supply pipe to the respirator for the diver to breathe.

[0005] For example, an existing patent with application number CN201920688221.0 discloses a diving breathing equipment, including an air supply device and a breathing device, the air supply device includes an air intake box and an air storage bottle, the breathing device includes a respirator and a connecting air pipe, the air intake box and the air storage bottle are connected by an air outlet pipe, the respirator and the air storage bottle are connected by a connecting air pipe, an air suction pump and a control device for controlling the operation of the air suction pump are arranged in the air intake box, an air intake pipe is connected to the air inlet end of the air suction pump, the air intake pipe is used to introduce air into the air suction pump, and the air is pressurized and introduced into the air storage bottle by the air pump, and finally enters the respirator through the connecting air pipe for use by divers.

[0006] In this patent, the suction pipe is directly connected to the vacuum pump. When the suction pipe sucks in non-air substances, it will directly enter the air pump and cause damage to the air pump. Utility Model Content

In the present application, the controller controls the operation of the air pump, and the air pump draws air from the outside through the second air inlet pipe, the first cavity, and the first air inlet pipe, and then discharges it through the inlet and outlet pipes for use by divers; the first cavity can separate the first air inlet pipe and the second air inlet pipe, and has the effect of caching air. The first air inlet pipe and the second air inlet pipe can form a staggered structure in the first cavity. After non-air matter enters the first air inlet pipe, it will sink to the bottom of the first cavity and will not enter the air pump to damage the air pump, nor will it affect the air suction of the air pump from the second air inlet pipe.

[0011] Furthermore, a drain port connected to the first cavity is provided on the side wall of the box body, and a water level switch is provided on the drain port.

[0013] Furthermore, the air outlet of the air pump is also connected to an air pressure switch through a pipeline, the air pressure switch is arranged in the box, and the air pressure switch is electrically connected to the controller. The air pressure switch can detect the air pressure output by the air pump. When the air pressure continuously reaches four atmospheres, it can prove that the respirator is not in use or the air outlet pipe is faulty, and the air pump is controlled to stop or the respirator alarms through a relay; when the air pressure switch detects that the air pressure output by the air pump drops to three atmospheres, the air pump is controlled to start through a relay.

[0014] Furthermore, the box body is also provided with a waterproof sealed compartment, in which a battery assembly is provided, and the battery assembly is electrically connected to the controller. The waterproof sealed compartment can cooperate with the box body to form a double-layer sealing structure to prevent water or other debris from entering the box body and affecting the battery.

[0015] Furthermore, a start switch and a charging port are also provided on the outer wall of the box, and both the start switch and the charging port are electrically connected to the controller, so as to facilitate starting the device or charging the device from the outside of the box.

[0016] Furthermore, the box body includes an upper cover and a lower shell, the upper cover and the lower shell are connected by screws, and a waterproof rubber ring is also provided at the connection between the upper cover and the lower shell, which can not only achieve the sealing and waterproofing of the box body, but also facilitate the disassembly of the box body and the maintenance of the equipment.

[0017] Furthermore, a handle is provided on the upper cover to facilitate carrying of the respirator.

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows: the diving respirator is provided with a first air inlet pipe, a second air inlet pipe, and a first cavity; the first cavity can separate the first air inlet pipe and the second air inlet pipe, and has the effect of caching air; the first air inlet pipe and the second air inlet pipe can form a staggered structure in the first cavity; after non-air matter enters the first air inlet pipe, it will sink to the bottom of the first cavity, and will not enter the air pump to damage the air pump, nor will it affect the air suction of the air pump from the second air inlet pipe.
