Description

  The present invention relates to an oxygen generator and a health promotion chair that can simultaneously perform a massage effect and oxygen suction using the oxygen generator.

  It is said that it is effective to absorb high concentration oxygen as a method to relieve fatigue in sports, work, various work, study, etc., and to get a refreshing feeling, refreshing feeling and arousal feeling. As means for generating and supplying oxygen, oxygen generators or oxygen concentrators (hereinafter referred to as oxygen generators) that enrich air and generate about 30% high-concentration oxygen are commercially available.

In this oxygen generator, an oxygen-enriched membrane unit and a vacuum pump are usually provided in a housing having an air intake port, and a conduit such as a tube is connected to the discharge side of the vacuum pump. It has a structure with a mouse that blows out 30% enriched air.
However, when such enriched oxygen is produced, the moisture in the air also reaches the mouse through the conduit from the vacuum pump, so if you run for a long time or use it in a humid time or place, Drops of water squirt from the mouse.

As a countermeasure, a drain is placed in the middle of the conduit, and condensed water is collected and removed as appropriate, but water drops and moisture attached to the inner wall of the upstream conduit from the drain to the vacuum pump. Cannot be removed. For this reason, there was a problem in terms of hygiene, such as the possibility of molds and germs breeding could not be eliminated and odors were generated.
As a countermeasure, it is necessary to remove the tube, clean the inside with a sterilizing liquid, and then vent and dry the tube. For this reason, there was a problem that it was cumbersome and unusable.

The tube can be removed and dried as described above in the case of an oxygen generator as a single instrument. However, if an attempt is made to configure the oxygen generator in the chair so as to suck the enriched oxygen while resting the body and enjoying a massage, etc., a part of the tube exists in the chair, especially from the drain device. Since the upstream conduit leading to the vacuum pump cannot be removed, water droplets and moisture attached to the inner wall of the conduit cannot be removed.
For this reason, it is practically difficult to incorporate the oxygen generator into a chair that can suck in enriched oxygen while massaging the body with a massage. Had to buy and use each.

  For this reason, not only is it uneconomical, but also it takes a lot of space for installation or arrangement, and furthermore, each of the vibrator and oxygen generator must be driven, stopped, and used for setting the operating time by separate controllers. There was a problem that it was very complicated.

  The present invention has been made to solve the above-mentioned problems, and its purpose is to remove moisture and water droplets in the system that guides oxygen-enriched air to the suction device by removing the conduit. The object is to provide an oxygen generator which can be removed automatically without any.

  In addition, another object of the present invention is to absorb oxygen enriched while massaging the body with a massage, and also incorporate a chair oxygen generator and a conduit system that guides oxygen enriched air to the mouse. Another object of the present invention is to provide a health promotion chair that can accurately remove moisture and water droplets from the inner wall of the conduit.

  In order to achieve the above object, the present invention provides an oxygen-enriched membrane in a housing, a vacuum pump connected to this with a suction pipe, and a conduit having a suction means at the tip on the discharge side of the vacuum pump. The heater is provided with a heater in which a heating element is arranged in the air intake portion and the flow passage that follows the housing, and the discharge side of the heater is connected to the suction pipe via a switching valve to operate the switching valve. Thus, during the required time, the connection between the oxygen-enriched film and the vacuum pump is turned off, the connection between the vacuum pump and the heater is turned on, and the heated air is circulated through the conduit.

  In addition, the present invention provides an oxygen-enriched membrane, a vacuum pump connected to the seat by a suction pipe, an air intake, and a circulation in a lower space of the seat of the chair body where a vibrator is disposed at least on the backrest. An oxygen generator having a heating element in the passage and a discharge side having a heater connected to the suction pipe via a switching valve is incorporated, and the discharge side of the vacuum pump passes through the chair and reaches the outside of the chair. It is characterized in that a conduit having a suction tool is connected to the tip of the pipe.

  According to the present invention, an oxygen-enriched membrane is used, the nitrogen content in the air is separated and removed by utilizing the difference in the rate at which molecules dissolve in the membrane, and the concentration is reduced to about 30% by reducing the pressure with a vacuum pump. However, when the oxygen-enriched air is generated and sucked, if the switching valve is operated, the connection between the oxygen-enriched membrane and the vacuum pump is released and at the same time a heater is installed on the suction side of the vacuum pump. Because it is connected, air is sucked into the heater, the air is heated in the flow passage, is dried air, sent from the vacuum pump to the conduit, and the water droplets and moisture adhering to the inner wall of the oxygen-enriched air conduit Evaporates to dryness.

  Therefore, the propagation of germs and molds is suppressed and the generation of odors is also suppressed, so that the hygienic condition can be improved, and the troublesome removal and cleaning of the conduit can be omitted, so that it is easy to use. can do.

  In addition, according to the chair of the present invention, a massage can be performed, and an oxygen generator is built in the space under the seat. While enriched oxygen can be sucked in, the muscle-relaxing effect is increased, and a refreshing feeling, comfort and refreshment can be simultaneously obtained.

  Moreover, even if the conduit is not removed and is passed through the chair, the water droplets and moisture generated by the generation of oxygen-enriched air as described above by the heater and the switching valve are attached to the inner wall of the conduit due to heat. Because it evaporates and dries, it is easy to maintain as a chair with a built-in oxygen generator, and since it is a single chair, it saves space and does not require the purchase of a dedicated oxygen generator. Since a single controller can be used to control the start / stop, time setting, strength and weakness of the vibrator and oxygen generator, it is possible to obtain an excellent effect that the usability can be improved.

The present invention operates a switching valve after a predetermined oxygen-enriched air generation time to turn off the connection between the oxygen-enriched membrane and the vacuum pump and turn on the connection between the vacuum pump and the heater for the required time. have.
According to this, since the drying in the conduit by the heater is automatically performed when the suction time of the oxygen-enriched air is over, the conduit can be maintained in an appropriate dry state without accumulating water droplets or moisture.

The conduit interposes a relay body filled with a titanium oxide photocatalyst.
According to this, since the oxygen-enriched air passing therethrough can be purified and deodorized and antibacterial can be achieved, hygienic oxygen suction can be performed together with ventilation with dry air by the heater.

Reference numeral 15 denotes a chair body, which has a seat portion 15a filled with a cushioning material and a backrest portion 15b inside a fiber or leather-based cover material, and armrest portions 15c and 15c embedded with a rigid material are fixed on both sides. ing.
Vibrators 16a and 16b are embedded in the seat portion 15a and the backrest portion 15b, respectively. The vibrator 16a of the backrest 15b is disposed at a relatively high level and a relatively low level corresponding to the waist.

An electric floor (electrode) 17 is embedded in the seat portion 15a at a position where the collar portion is received, and a power feeding cable for this is connected to a potential input jack of a panel attached to the side surface of the seat portion.
A vacant chamber 18 is defined in the seat portion 15 a below the embedded portion of the electric floor 17, and the oxygen generator S is stored and fixed in the vacant chamber 18. That is, as shown in FIGS. 1 and 2, the oxygen generator S is formed by screwing upright plates 101, 101 in the bracket 1 c on the lower surface of the housing with left and right rigid side plates 19, 19 fixed to the empty chamber 18. It is fixed by fixing (see FIG. 2).
The bottom 150 of the seat portion 15a can be opened and closed with a fastener so that the oxygen generator S can be stored and inspected easily.

The air inlet of the oxygen-enriched membrane unit 2 faces the side of the seat, but the portion is covered with a cover material so that it cannot be seen from the outside.
The high-concentration oxygen conduit 7 connected to the discharge side of the vacuum pump 3 is guided through the back portion 15b as shown in FIGS. 7 and 8, and the side portion of the back portion 15b as shown in FIGS. It is connected to the conduit 7 ′ via a relay part 9 whose side is fixed to the pipe 7 ′. The tube 7 'has a required length and is equipped with a suction tool 8 at the tip. A holder 152 for hooking the band 8b of the suction tool 8 is provided on the side of the backrest 15b.

  In the backrest portion 15b, an electric heating heater 19 of about 20 to 30 W, for example, is embedded in a portion where the back hits, and at a level corresponding to the upper portion from the shoulder, at least two of the full range are included. A speaker unit 20 is embedded.

As shown in FIG. 9, a power supply panel including an AC power supply connection portion and the like is provided on the rear surface portion of the seat portion 15a, and a remote controller 21 is provided at a portion of the seat side portion opposite to the panel. Are arranged so that they can appear and disappear.
The remote controller 21 includes a main power switch, an on / off switch / timer for a vibrator, an on / off switch / timer for a thermal heater, and the like, and is connected to the controller 12 of the oxygen generator S. Accordingly, the use condition can be set by the timer 212.
In addition, an operation element for potential treatment, an operation element for speaker on / off / volume adjustment, and the like may be incorporated.

When using the chair of the present invention, the user sits on the seat 15a, places his back on the backrest 15b, and selects a desired treatment. In order to suck high-concentration oxygen, the suction tool 8 is attached to the neck or head, and the mouse 8a is directed to the mouth.
Then, “oxygen” is selected with the remote controller 21 and the on / off switch 211 is operated. If it carries out like this, it will operate for 15 minutes and will stop automatically, for example. In addition, when it has a timer, it can select from 10 minutes, 15 minutes, 20 minutes, 30 minutes etc., for example.

In this way, the switching valve 5 of the oxygen generator S communicates the suction pipe 6b that connects the discharge pipe 6a of the oxygen-enriched membrane unit 2 and the suction part of the vacuum pump 3, and disconnects the communication with the pipe 6c of the heater 4. To maintain.
As a result, air is continuously taken into the oxygen-enriched membrane unit 2 and nitrogen in the air is separated and removed using the difference in speed at which molecules dissolve in the membrane and sucked into the vacuum pump 3 from the suction pipe 6b. By reducing the pressure, high concentration oxygen having a concentration of about 30% is generated.
This oxygen-enriched air is continuously sent from the vacuum pump 3 to the conduits 7 and 7 ', and is ejected from the mouse 8a and sucked.

When the set time, for example, 15 minutes elapses, the switching valve 5 is activated, and the valve element disconnects the communication between the discharge side pipe 6a of the oxygen-enriched membrane unit 2 and the suction pipe 6b of the vacuum pump 3. The supply of enriched air is stopped. ,
At the same time, the operation of the switching valve 5 causes the suction pipe 6 b of the vacuum pump 3 to communicate with the discharge-side pipe 6 c of the heater 4. The linear heating element 44 of the heater 4 may be operated from this point in time, but may be supplied with power before the switching and may be in a preheated state.

  By doing so, since the oxygen-enriched membrane unit 2 does not work, the creation of oxygen-enriched air is stopped, while the suction force of the vacuum pump 3 acts in the heater 4, so that the air intake hole 410 and the inside of the housing 4 a The air is sucked into the air and is heated by the heating element 44 while passing through the flow passage 45. As a result, the heated air passes through the pipe 6c from the discharge port 420 and is sucked into the vacuum pump 3 from the suction pipe 6b. It circulates through the conduits 7 and 7 'continuously from the section and is ejected from the mouse 8a. This is maintained for a set time, for example in the range of 60 to 120 seconds.

  Since it is not a simple air blow or a normal temperature air blow, but a heated air blow from which moisture has been removed by heating, water droplets or moisture adhering to the inner walls of this through continuous passage through the conduits 7 and 7 ' Is evaporated and discharged. Therefore, while the suction pipe 6b and the conduit 7 are incorporated in the chair and cannot be removed, the bacteria and mold of the suction pipe 6b and the conduits 7 and 7 'are prevented from breeding and the generation of odors caused by them. it can.

  When such a drying process is finished, the heating element 44 stops its operation or the output is switched to the preheating mode, while the motor of the vacuum pump 3 is stopped and the valve body of the switching valve 5 moves, and the oxygen-enriched membrane unit 2 The discharge side pipe 6a and the suction pipe 6b of the vacuum pump 3 are communicated, and the communication between the suction pipe 6b of the vacuum pump 3 and the discharge side pipe 6c of the heater 4 is cut off. As a result, the oxygen-enriched air can be generated and supplied again.

In addition, when the titanium oxide photocatalyst 12 such as a granular pellet is filled in the relay part 9, it is activated by the light transmitted through the first part 9a and purifies the oxygen-enriched air passing therethrough. Deodorizing action and antibacterial action.
Therefore, clean oxygen-enriched air can be sucked together with the drying with the heated air.

When it is desired to massage at the same time as the suction of oxygen, vibration may be selected by the remote controller 21, and the vibrators 16a and 16b are activated to stimulate the back, waist and thighs.
Therefore, it is possible to receive an effective massage by vibration while taking high concentration oxygen into the body. If the warming heater 19 is also incorporated into the operation at the same time, the back and waist can be warmed, so that even better massage and refreshing effects can be created.

Further, if a sound output unit of an external desired acoustic device such as a CD or a DVD is connected to the sound input jack 61, sound is diffused from the speaker unit 20, so that a more comfortable situation can be created.
In addition, when it is desired to perform potential therapy alone or in combination with vibration and / or oxygen suction, an external potential therapy device is connected to the potential input jack of the side panel. By doing so, since a high voltage is applied to the electric floor 17, potential treatment can be easily performed without requiring a dedicated chair or electric floor.
