Description
Technical field
The present invention relates to a kind of Swimming exerciser, especially a kind ofly can provide the safe swimming exerciser of underwater security for beginning swimmer.
Background technology
Swimming is on the water by technical ability that is floating, that advance at underwater exercise by means of the action of self limbs of relying on oneself, be one of aerobic exercise of all liking of men and women, old and young, adhere to for a long time swimming and can improve cardiovascular system, improve lung capacity, strengthen skin blood and circulate, build up resistance, strengthen adaptive faculty of temperature etc.
At present, beginning swimmer generally uses some buoyancy aid article (such as lifebuoy (clothing) in learn swim process, foamed plastics, buoy, flutter board, floating sleeve etc.) safety guarantee is provided, but often easily there is rollover phenomenon or gas leakage in use in the aid of the buoyancy type such as lifebuoy, user is caused to choke water or drowned, serious health and the life security even threatening user, poor stability, secondly need both hands to have in arms in use or be enclosed within the posture such as waist and oxter, the both hands of user will be taken like this or hold out the water surface by more than user's chest, thus cause the health of user to be very limited, learn swim weak effect, and often use lifebuoy class aid that people can be made to produce dependence, long-term at water surface activities, user's water of choking is caused to agonize because rollover phenomenon easily occurs lifebuoy class aid, especially after experience chokes water several times, heart will create the feared state of mind to swimming, be difficult to make beginning swimmer grasp swimming skill fast, the most important thing is existing swimming aid to drowning person without effective rescue equipment, to slip out of the hand once beginning swimmer or turn on one's side the dangerous situation such as upside down, distress signals cannot be sent, delay the time of succouring, and the constraint of aid makes user be difficult to break away from time, thus larger danger can be brought for user.
Summary of the invention
The object of the invention is to provide a kind of safe swimming exerciser for the deficiencies in the prior art, respiratory system and head-mounted display are combined, video study is carried out while making beginning swimmer practise swimming under water, and do not hinder the trick action of beginning swimmer, improve practice effect, have that practice effect is good, security high, be suitable for the waters learn swim of beginning swimmer in the little degree of depth.
The technical solution adopted in the present invention:
