   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   The present invention will now be described in details with reference to the companying drawings and embodiments, in which same references refer to similar parts. 
   Embodiment 1 
   As shown in  FIG. 1(   a ), a leisure fitness equipment with oxygen-supplying function comprises a running machine 101 , an oxygenerator, a control device  103 , an oxygen-supplying pipe, an automatic disengaging means  111 , an oxygen inhalator  112  and an oxygen mask. 
   The oxygenerator is a micro PSA oxygenerator  1021 , which is set on the base frame  110  of the running machine 101  and integral with the running machine 101 . The micro PSA oxygenerator  1021  comprises a micro oil free air-boost compressor  1041 , two micro zeolite molecular sieve adsorption towers  1051 , a control valve 1061 , a buffer tank  1071 , an air filter  1081  and a flow control valve  1091 . The oxygen-supplying pipe is connected between the outlet of the oxygenerator and the automatic disengaging means  111 . Air is taken into the micro oil free air-boost compressor 1041  through the air filter  1081 , enters into the two zeolite molecular sieve adsorption towers  1051  via the control valve  1061  in an alternately manner, then passes through the buffer tank  1071 , the flow control valve  1091 , the oxygen-supplying pipe, the automatic disengaging means  111 , and finally is supplied for exercising people via the oxygen inhalator  112  or oxygen mask. In which, the micro zeolite molecular sieve adsorption tower  1051  is a pressure swing adsorption (PSA) zeolite molecular sieve, which can produce oxygen in accordance with the medical standard. Thereby, the micro PSA oxygenerator  1021  can provide enough oxygen and improve the oxygen concentration for oxygen shortage places, such as sites installed with a massage sofa, a running machine, a fitness bicycle or a skiing machine; alternatively, oxygen produced may be directly supplied to users via an oxygen inhalator  112 . 
   The leisure fitness equipment further comprises an oxygen inhalator  112  having two ends, wherein one end is connected to an end of the automatic disengaging means  111 , and the other end is accessible for users. The end of said oxygen inhalator  112 , which is accessible for users, can be further connected to an oxygen mask. The oxygenerator  1021  is directly connected to or is indirectly, via a changeover valve, connected to an end of the oxygen-supplying pipe. 
   A mechanical or an electrical automatic disengaging means  111  having two ends is set on the top of the running machine  101 , one end of which is fixed on the control panel  103  and connected with the other end of the oxygen-supplying pipe, the other end of the automatic disengaging means  111  is detachably connected to the oxygen inhalator  112 . When a user inhales oxygen with an oxygen inhalator  112  or an oxygen mask, once the user falls down, to whatever directions, due to the preset gravity limit or tension limit, the oxygen inhalator  112  will be released from the user automatically. 
   The automatic disengaging means  111  is shown in details in  FIG. 1(   b ), wherein one end of the joint  1110  is connected to the oxygen inhalator  112 , the other end is set inside a base on the control panel  103  and presses against a release spring  1112  set on the bottom of the base  1111 , so as to keep the release spring  1112  in a compressed state and generate a preset pressure limit. In order to position the joint  1110  inside the base  1111  and make sure the joint  1110  can be released from the base  1111  once the user is falling down, a positioning device is adopted which is constructed of a wedge  1113 , a positioning pin  1114  and a return spring  1115 , meanwhile a groove is set on the joint  1110  where the joint  1110  contacts with the positioning pin  1114 . In normal use, by the return spring  1115 , the positioning pin  1114  is pressed tightly in the groove of the joint  1110 , and the joint  1110  is fixed inside the base  1111 . Once the user falls down, the oxygen inhalator  112  generates an upward force, in addition, due to the counterforce by the release spring  1112 , the joint  1110  is forced to move upwardly from the bottom of the base  1111 , which pushes the positioning pin  1114  to move outwardly with the aid of the return spring  1115 . Once the positioning pin  1114  is released from the groove, the joint  1110  is released from the base  1111 , thereby the oxygen inhalator  112  is released from the user. 
   The control device  103  is in the form of a control panel setting on the top of the running machine, for controlling and setting the working state of the running machine  101  and the micro-oxygenerator  1021 . 
   Embodiment 2 
   As shown in  FIG. 1(   c ), the difference between the present embodiment and the embodiment 1 is that, the oxygenerator is a micro membrane oxygen-enriched machine  1022 , and set at the underside of the control panel  103  on the top of the running machine  101 . Said micro membrane oxygen-enriched machine  1022  comprises a micro oil free vacuum pump  1042 , a membrane assembly  1052 , a buffer tank  1062 , a condensed water tank  1072 , and a fan  1082 . The oxygen-supplying pipe is connected between the outlet of the oxygenerator and the automatic disengaging means  111 . Air is blown into the membrane assembly  1052  by the fan  1082 , and passes through the buffer tank  1062 , vacuum pump  1042 , condensation water tank  1072 , oxygen-supplying pipe, enters into the automatic disengaging means  111 , and finally is supplied for exercising people via the oxygen inhalator or oxygen mask. The micro membrane oxygen-enriched machine may use macromolecule osmosis membrane, so as to obtain an oxygen-enriched air with oxygen concentration of 25%-35%. 
   A flow control device may be installed on the oxygen inhalator so as to control the flow rate of the oxygen. 
   Embodiment 3 
   As shown in  FIG. 2(   a ), the leisure fitness equipment with oxygen-supplying function comprises a massage sofa  201 , an oxygenerator, a control device  203 , an oxygen inhalator and an oxygen mask. 
   The oxygenerator is a micro PSA oxygenerator  2021 , set on the base frame  210  of the massage sofa and integral with the massage sofa  201 . 
   The control device  203  is a controller convenient for users to hold in hand, for controlling or setting the working state of the massage sofa  201  and oxygenerator  2021 . 
   Embodiment 4 
   As shown in  FIG. 2(   b ), the difference between the present embodiment and the embodiment 3 is that, the oxygenerator is a micro membrane oxygen-enriched machine  2022 . 
   The micro-oxygenerator can be controlled separately from the leisure fitness device, with the control device inherently equipped with the micro-oxygenerator. 
   As shown in  FIG. 3 , a control circuit board, installed inside the micro-oxygenerator of the leisure fitness equipment with oxygen-supplying function of the present invention, consists of a MCU (Micro Control Unit) chip  301 , a power supply circuit  302 , a monitoring and alarming circuit  303 , a working state monitoring circuit  304  and control switches  305 ,  306 ,  307  for controlling the micro-compressor, the fan and the electromagnetic valve of the micro oxygenerator. Wherein MCU  301  is connected with the power supply circuit  302 , the monitoring and alarming circuit  303 , the working state monitoring circuit  304  and the control switches  305 ,  306 ,  307  respectively. Thereby, through the control switches  305 ,  306 ,  307 , the micro-compressor, the fan and the electromagnetic valve are controlled by the MCU  301  respectively. 
   As shown in  FIG. 4 , MCU, the central controller of the whole equipment, controls the operation of every part of the whole equipment and also monitors various working states of the equipment. 
   As shown in  FIG. 5 , the desired DC voltages are obtained through a transformer and an AC/DC converter, and is further stabilized by a voltage regulating module. The VP and VDD outputs of the module are used as power supplies for different parts of the system: the VP is for the electromagnetic valve, the compressor and the fan, and the VDD is for various chips. 
   As shown in  FIG. 6 , the control switch circuit has two parts, each comprising a MOS transistor and a relay system. One is used to control the electromagnetic valve and the other is for the operation of the compressor of the micro PSA oxygenerator. The control switch circuit works according to different control signals from the MCU, and thereby generates oxygen efficiently by way of PSA. 
   Alternatively, the micro-oxygenerator of the present invention can work under the control of the leisure fitness device. 
   As shown in  FIG. 7 , when the micro-oxygenerator works under the control of the leisure fitness device, the two parts are effectively isolated through a control interface which uses low-voltage signals to control relatively high-voltage part of the system. This technique helps avoid interferences between the micro-oxygenerator and the leisure fitness device. As shown in  FIG.8 , a current limiting resistor R is used to control the drive current of the photo coupler, and also keeps the current within the rated current of the port of the MCU of the leisure fitness device. An optoelectronic isolator EL817 is used to effectively isolate the signals between the leisure fitness device and the micro-oxygenerator, so that the possibility of interferences between each other is reduced to minimum. With the effect of the optoelectronic isolator, the electronic signals from the MCU drive the switch to work. The normally-on switch is connected with the PCB of the micro-oxygenerator, to control the working power supply of the micro-oxygenerator. In this way, the micro-oxygenerator can be effectively controlled by the controller of the leisure fitness device.
