Embodiment 1
As shown in FIG. 1(a), a leisure fitness equipment with oxygen-supplying function comprises a running machine101, 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 machine101 and integral with the running machine101. The micro PSA oxygenerator 1021 comprises a micro oil free air-boost compressor 1041, two micro zeolite molecular sieve adsorption towers 1051, a control valve1061, 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 compressor1041 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

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.
