Field of the Invention The present invention relates to an oxygen concentrator and a humidifier, and more particularly to a humidifier for carrying out moderate humidification of concentrated oxygen. And an oxygen concentrator for oxygen inhalation therapy. [Prior Art 3] In recent years, patients suffering from respiratory system organ diseases such as asthma, emphysema, and chronic bronchitis have an increasing tendency, and one of the most effective methods of the treatment is oxygen inhalation therapy. The aforementioned oxygen inhalation therapy causes the patient to inhale oxygen or an oxygen concentrated gas. The oxygen supply source is known to have an oxygen concentrator, liquid oxygen, high pressure oxygen, etc., and an oxygen concentrator is mainly used in home oxygen therapy because of the convenience of use method or ease of storage management. The oxygen concentrating device is a device which supplies about 21% of oxygen present in the air and then supplies it. Among them, a membrane type oxygen concentrator using an oxygen-concentrated membrane that selectively permeates oxygen, and a pressure-variable adsorption-type oxygen concentrator using an adsorbent capable of preferentially adsorbing nitrogen or oxygen are used, but high From the viewpoint of the concentration of the oxygen-concentrated gas, the pressure-variable adsorption-type oxygen concentrator has become the mainstream. The pressure fluctuation adsorption type oxygen concentrating device alternately performs pressure, adsorption step, decompression and desorption steps, and continuously generates a high concentration of oxygen concentrated gas, and the pressurizing and adsorbing steps are performed by compressing the compressor. The air is supplied to the zeolite with the molecular sieve under the pressure of 5A type or BX type 'Li-X type, which is selected as the adsorbent 3 201134509 which is first selected to adsorb nitrogen, so as to obtain the adsorption tube of the (10). In the system, the pressure in the adsorption tube is decompressed by 丨& decompression and the pressure of the step JA is also removed, /ir, and then the nitrogen adsorbed on the adsorbent is washed, thereby entering the following However, « -g ^ ^ , 丄 ° and the regeneration of the attached agent. In the #oxygen concentrating device, since the zeolite used as the nitrogen adsorbent has a property of adsorbing moisture, the X-oxygen concentrated gas is generated and discharged in a state where the humidity is hardly contained. In order to prevent the patient's nasal cavity or oral cavity from being dried, the oxygen concentrating device is equipped with a heart that has been supplied with the oxygen-concentrated gas in a humidified state, so that it is wet (four) is high in humidifying performance, and thus, as disclosed in Japanese Patent Laid-Open No. (7) The blessings of the blessings are used to make the bubbles of the bubbled air bubbles (4) and moisture, thereby humidifying the H-gas in a dry state (Patent Document)丨). When using a humidifier that uses water as a humidifying source, the user of the farm must use regular water supply and a humidifier. It will become a patient's own operation of removing the H from the oxygen concentrating device and performing the filling of the fresh internal washing and humidifying water to reinstall the humidifier. The treatment method of the humidifier itself is very simple for healthy normal people. On the other hand, especially the elderly patients with inflexible fingers are installed to the humidifier when the cover is not fixed. The main body of the oxygen concentrator, in addition, the installation of the port is not complete, and the oxygen is caused by the oxygen leakage at the connection portion. The solution to this problem is not known as the horizontal arrangement of the humidifier in the horizontal direction. The press-in type humidifier is a humidifier that is installed in the up-and-down direction, and is used to connect the lid of the humidifier to a fixed position. 4 201134509 Structure, the lower part of the humidification container and the oxygen concentrator A fitting structure of the main body or the like (Patent Document 2). Further, a method in which a coupling portion of an oxygen concentrator using a humidifier is used to securely mount a humidifier using a coupler, or a mechanical type is used. A humidifier device used as a position confirmation sensor, such as a switch or an electrode, a photo sensor, or the like, for automatically confirming that the humidifier is reliably mounted on the body of the oxygen concentrator (Patent Document 3).Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. Hei. The oxygen wave reduction device requires miniaturization of the device, and further requires design. Therefore, the humidifier mounting portion of the oxygen concentration device has almost no sufficient space. Therefore, the installation of the humidifier using a coupler or the like is In order to prevent such an accident, the sorghum is often in a difficult state, and the oxygen concentrator is often used when the humidifier is poorly connected, or when the humidifier itself is used, an abnormal alarm is issued. A humidifier position detecting device for notifying the patient that the humidifier has been reliably connected is used. However, in the current humidifier detecting device using a mechanical switch or an electrode, although humidification occurs, although humidification occurs The device is not installed properly but has not issued an alarm. 5 201134509 The opposite is true, although it is actually installed, it still issues an error detection or false alarm. The problem is that the humidifier is installed in the upper part of the humidifier due to the installation mode, and the inlet portion of the humidifier is provided with the humidification oxygen inlet port, the humidification completes the oxygen discharge port, and on the oxygen concentrator side. The inlet nozzle and the outlet nozzle are fitted and connected. Therefore, the upper portion of the humidifier is fixed to the body of the oxygen concentrator, and the position of the switch for position detection is structurally the side of the container below the humidifier. Therefore, due to the relationship between the strokes, the contact of the switch is poor. In order to make the humidifier detection device actuate, for example, the humidifier container can be installed or removed in the up and down direction, and the humidifier The detection switch is disposed on the lower side of the container to solve the problem, but water droplets attached to the outside of the humidifier container may penetrate the detection switch, which may cause malfunction or malfunction of the machine. On the other hand, most of the containers used in the humidifier use transparent materials, and the water for humidification can be externally confirmed to enter the inside. When the sensor is detected by the humidifier using the light sensor, in addition to detecting The problem of poor measurement, the high cost of the photosensor itself can also become a problem. Means for Solving the Problems The present invention has found the following invention as a solution to the aforementioned problems. That is, the oxygen concentrating device of the present invention is a water humidifier for separating oxygen in the air to produce an oxygen concentrated gas and humidifying the oxygen concentrated gas, wherein the oxygen concentrating device has a water humidifier accommodating portion for arranging the water humidifier, and the water humidifier accommodating portion has a humidifier supporting portion that supports the water humidifier in the installation direction of the water humidifier and has elasticity The component is used to detect the position of the elastic member generated by pushing the water humidifier into the direction of the installation of 201134509 to the position of the connection. ',' 7 The σ wet device is fixed with the addition Wet device. The 疋 mechanism is in the position of the connection, and the invention provides an oxygen concentrating device, which has a switch cover capable of accommodating the mouth of the water in the water plus the mouth of the stagnation ρ, the county Pushing the water humidifier in the direction of connection, and changing the position to the water humidifier by pressing to set the position of the water humidifier = ^ special force, the fixed port P of the state of the crotch portion is particularly the water humidifier system Having a connection that can be in the vertical collapsing device, and the enthalpy of oxygen is concentrated in the water that has been allowed to be filled: ·=: the bomb = undetected position' and the closed switch cover 2 is: The detection position of the sensor. The "Yi" component is a further == oxygen concentrating device, which is characterized in that the Fu 1 is loaded with the impeller and has the water humidifier that does not fall into the water connected to the fixed m ° due to the loaded weight (4) The spring of the connection 疋 position is always supported by the spring. The water humidifier receives two ==' and the sensation-type contact switch is the water on the fresh side of the water. Humidifier position. - Body surface inspection and further provided by the present invention, the device has a resilient member that supports the water humidifier in the installation direction of the water humidifier, and (b) has: The water is full of the test|月## t Α Γ* " The system pushes the direction toward the women's clothing, and detects the change of the position of the water humidifier generated by the elastic member 201134509 to the connection position; The fixing mechanism fixes the water humidifier at a fixed position, and has a humidifier receiving portion for accommodating the water humidifier and having a switch cover at the receiving opening, and pressing the water to humidify by closing the switch cover And the fixing mechanism changes the position of the connection to the water humidifier by expanding and contracting the elastic member Further, the fixing mechanism is maintained at a fixing portion in a state in which the switch cover is closed. According to the present invention, when the installation of the water humidifier is incomplete, an alarm can be surely issued, thereby releasing the water. The humidifier is poorly installed, and an oxygen concentrating device that is safer to use is provided.

First, the raw material air sucked in from the outside is sucked by the external air suction device for removing foreign matter such as dust, which is sucked into the filter 101 and the air intake silencer 102. The filter 101 is preferably one having a collection efficiency higher than that of the HEPA filter. Air towels typically contain about 21% oxygen, 77% nitrogen, 8% argon, carbon dioxide or other gases of 1.2%. The oxygen concentrator described above must concentrate oxygen and take it out as a breathing gas. The raw material air is pressurized by the compressor 103, and the adsorption tube 1〇5 filled with the adsorbent composed of the zeolite which selectively adsorbs nitrogen compared to oxygen is sequentially switched by the flow path switching valve 104'. The adsorption cartridges 1〇5a, 1〇5b of the object are supplied 'to thereby selectively adsorb and remove about 77 Å contained in the raw material air. Nitrogen gas can be continuously produced by separating unadsorbed oxygen. As the adsorbent, a molecular sieve of 5A type, 13X type, Li-X type, MD-X type or the like is used. The adsorbents have the property of selectively (10) nitrogen in the pressurized state compared to oxygen, and have the property of adsorbing water earlier than nitrogen. Therefore, the generated oxygen-concentrated gas becomes a dry stateless gas which does not contain moisture. The adsorption cylinder is formed of a cylindrical vessel filled with the adsorbent, and a multi-cylinder type of one-cylinder, two-cylinder or three-cylinder or more is used, but in order to continuously and efficiently produce oxygen concentration from the original gas. For gas, it is advisable to use two or more cartridges. Further, in addition to the use of the oscillating type air compressor, the above-described compressor 1 〇 3 also uses a rotary type air singular compressor such as a spiral type, a rotary type, or a scroll type. Further, the power source that drives the power-off 103 can be either AC or DC. The oxygen-concentrated gas, which is not a component of the oxygen adsorbed by the adsorption cylinders 1 to 5, flows into the product tank 10 201134509 108 via the anti-back valve 1G7 provided so as not to flow back toward the adsorption cylinder, and is temporarily stored. On the other hand, in order to adsorb nitrogen from the newly introduced raw material air, it is necessary to desorb the nitrogen adsorbed to the adsorbent to regenerate the adsorbent. Therefore, the adsorption column 105 in the pressurized state in which the adsorption step of adsorbing nitrogen and generating oxygen is completed can be switched to the atmospheric pressure or the reduced pressure state by the flow path switching valve 104, and the desorption step of desorbing and removing nitrogen is performed. Thereby the adsorbent is regenerated. At this time, in order to improve the desorption efficiency, the product end side of the adsorption tube in one of the adsorption steps may be connected to the product end of the adsorption tube in the other desorption step, or by the product. The tank counteracts a portion of the oxygen concentrated gas as a flushing gas. In general, when the nitrogen is desorbed and exhausted, a large airflow sound is generated as the high-pressure gas is discharged from the adsorption cylinder, and therefore, the exhaust muffler 503 is generally used. The oxygen-concentrated gas system generated from the raw material air is temporarily stored in the product tank 108. The oxygen-concentrated gas stored in the product tank contains, for example, 95% of high-concentration oxygen, and the supply flow rate and pressure are controlled by the pressure regulating valve 109 or the flow rate setting mechanism 110, etc., and then supplied to the humidifier 2 and moderately added. Wet, supply to the patient. The humidifier 2 can use a water-free membrane that is permeable to moisture permeating the membrane by a water such as Nafion or polyimide to permeate the moisture from the outside air and then humidify the oxygen-concentrated gas in a dry state. A humidifier, or a bubble humidifier using water as in the present invention, or a surface evaporative humidifier. Further, the oxygen concentrator 1 has a mechanism for detecting the setting of the flow rate setting means 110, controlling the number of rotations of the motor of the compressor 103 by the control means 401, and controlling the amount of supply air to the adsorption cylinder. Thereby, when the flow rate 11 201134509 is set to a low flow rate, the amount of oxygen generated is reduced by suppressing the number of rotations of the motor, and the reduction in consumption power can be achieved. As shown in Fig. 3, the humidifier 2 fills the water humidifier container 202 with water as a humidifying source, and after being sealed by the humidifier cover 203, the humidifier 2 is placed in the humidifier housing chamber of the oxygen concentrator body. The oxygen introduction tube 204 and the oxygen discharge tube 205 and the connection position of the inlet port 206 and the discharge port 207 of the humidifier cover 203 are aligned in the vertical direction. At this time, when the humidifier cover 2〇3 is not closed to the predetermined position, the position detecting protrusion 208 is recessed on the bottom surface of the container attached to the water humidifier as described in Japanese Laid-Open Patent Publication No. 2005-185415. The portion 209 does not match, and the humidifier cannot be completely stored in the lower portion of the storage chamber. As a result, the switch cover 203 of the humidifier storage chamber 202 shown in Fig. 1 cannot be closed. In the oxygen concentrator of the present invention, the water humidifier 2 in which only a predetermined amount of water is filled in the container is installed in the storage chamber 202, and the humidifier is not connected to the main body of the oxygen concentrator. The water humidifier 2 is supported by the mounting direction by the elastic body 213 such as a spring, and the elastic body is compressed by pressing the water humidifier downward, thereby being fixed by a fixing mechanism at a predetermined position. fixed. The oxygen introduction port 206 and the oxygen discharge port 207 of the humidifier cover 203 and the oxygen introduction pipe 204 and the oxygen discharge pipe 205 on the apparatus main body side fitted thereto are surely installed if they do not reach the predetermined position, and are elastically fitted 213. When pulled back, the switch cover 203 cannot be closed, and the user can visually recognize the installation failure of the humidifier. The fixing mechanism may also be a coupling connection member disposed between the humidifier cover and the oxygen introduction tube or the oxygen discharge tube. However, as shown in FIG. 6 of the embodiment, the switch cover 203 of the humidifier should be used. 12 201134509 Ordering agency. Thereby, without adding a new fixing member, the humidifier 2 is pressed down to a predetermined position only by the action of the patient itself closing the switch cover 203, and the humidifier and the oxygen concentrator body can be reliably connected at the predetermined position, and The humidifier connection can be completed by the locking mechanism of the switch cover. As shown in FIG. 6, the inside of the switch cover 203 is provided with a convex portion 215, thereby pressing the upper end of the inlet port 206 and the discharge port 207 of the humidifier cover, and is provided by the handle 216 of the switch cover 203. The claw portion 217 of the root portion is fastened to the hook portion 218 on the side of the humidifier accommodation chamber, the switch cover is fixed in the closed state, and the humidifier is connected at a predetermined position. On the other hand, by pulling the handle 216 toward the front side, the hook portion 218 is disengaged from the claw portion 217 to release the fixing of the switch cover. If the connection position is not at the predetermined position, the pressure of the elastic body pushes the humidifier upward, and the switch cover 203 is opened and closed, so that the connection state can be easily visually recognized. Further, since the insertion tube of the supply means of the oxygen-concentrated gas is bent and caused to block, and the pressure inside the humidifier container rises, the switch cover 203 can be closed to fix the humidifier 2 at a predetermined connection position. Prevent the humidifier container from floating upwards and prevent oxygen: 3⁄4 leakage. The sensor for detecting the mounting position of the humidifier can use a mechanical switch such as a contact switch, or various position detecting mechanisms such as an electrode and a photo sensor. The contact switch can be used as the cheapest and truly detectable sensor. Considering the possibility that the user installs the humidifier container 20 in a state of being wetted when the humidifier container is washed or replenished with water, the sensor for mounting the position detection should have a waterproof function. . The sensor reaches the connection by pushing the direction of the humidifier. 13 201134509

(C) shows a closed humidification state. The water-humidifier state '(B) shows a state in which a water humidifier is installed, and the L-shaped member 211 of the accommodating chamber 202 in a state in which the water-humidifier is completely connected to the switch cover after the switch cover is attached 4 is shown in the back surface of which is supported by the spring 213' and the humidifier 2 is installed in the accommodating chamber 02 in a state of being filled with a predetermined amount of water, and the water humidifier 2 is transmitted through the L-shaped member 2 It is supported while floating, and the sensor does not perform position detection. Therefore, the humidifier detecting lever 212 disposed behind the L-shaped member 211 on the side surface of the humidifier does not move downward in a state where the humidifier has been loaded, and closes the switch cover 203' of the humidifier housing chamber. The switch cover 203 pushes the water humidifier 2 downward, whereby the humidifier detecting lever 212 of the L-shaped member 211 moves downward to become a structure for detecting that the humidifier is attached to the contact switch 214. The humidifier detecting rod 212 is supported by a spring 213 which determines the spring constant of the 201134509. When the water is filled in the water humidifier 2 to a prescribed full amount of water, the weight of the humidifier does not fall downward when the water is filled. . Moreover, by closing the switch cover 203' of the humidifier accommodation chamber 202, the humidifier detection rod 212 of the L-shaped member 211 is moved downwards' and the action is transmitted to the contact switch 214 as a humidifier detection switch. This detects that the humidifier is set correctly. The humidifier detects the open relationship to display or alert the user to the alarm when the presence of the humidifier cannot be detected, whereby the oxygen concentrator can be safely used. In this way, if the humidifier is not properly installed in the fixed position, the humidifier will be pushed up by the spring, and the humidifier switch cover can be opened to visually recognize the installation abnormality, and thus the abnormal alarm can be issued to prevent the addition. The switch cover of the wet device is forgotten to close. In the past, the 'humidifier detection switch was mostly installed on the side of the humidifier vessel' because of the lateral distance between the inlet nozzle and the outlet inlet of the humidifier cover, and the side of the humidifier vessel. The amplitude of the moving distance between the detecting switch and the detecting switch is different, so many false detections are made. On the other hand, if the L-shaped member 211 is used as the humidifier supporting member in the present invention, the mounting direction of the humidifier 2 can be made the same as the moving direction and distance of the humidifier detecting lever 212, and the mounting position can be prevented. False detection. Moreover, the humidifier detecting switch 214 is not directly actuated by the water humidifier container 202, but is indirectly operated by the humidifier detecting rod 212 of the L-shaped member 211, thereby the position detecting switch The position is set away from the bottom or side of the water container 2 〇 2, which prevents the sensor from malfunctioning due to the water leakage of the humidified water. Further, the oxygen concentrator has a cooling fan for cooling the heat generating member such as a compressor or an electric component, and discharging the cooling heat to the outside of the casing. 15 201134509 Therefore, the device will become a negative pressure. The humidifier must be replenished with water and placed outside the casing of the oxygen concentrator, so when the humidifier detection switch is directly mounted to the casing, the cooling wind accompanying the dust will be detected by the humidifier. The gap between the test switches flows into the casing, which may cause the malfunction of the humidifier detection switch. As shown in the present invention, by means of the humidifier detecting lever, a sensor type can be disposed inside the casing, and the cooling air containing the dust does not pass through the humidifier to detect the switch, thereby preventing such a malfunction. INDUSTRIAL APPLICABILITY The oxygen concentrator of the present invention is used as a medical oxygen concentrating device, and is used as an oxygen inhalation therapy for patients suffering from respiratory system diseases such as asthma, emphysema, and chronic bronchitis. Oxygen supply source. Further, by using the mounting structure of the water humidifier which is a feature of the present invention, the installation of the humidifier can be minimized, and the oxygen concentrating device which is safe or suitable for use can be utilized.
