However, as described above, even if sterilization by an ultraviolet lamp is performed in a state where the air has a low density, the sterilization effect is not remarkable, and it can be said that the air cleaning function is not effectively performed.
In view of the above-mentioned drawbacks, the present invention provides an air purifier for effectively purifying the air, and at the same time providing the high oxygen-containing air of the present invention to further enhance the practicality.

  A pressure chamber, an activated carbon filtration network, an oxygen generator, and an ozone generator are provided in the box, and a stable pressure chamber is formed in the pressure chamber by a compression unit and an ultrafine particle filter (ULPA). Is provided with a short wavelength ultraviolet light source, and the compression unit forces air into the pressurizing chamber through the activated carbon filtration network, and the efficiency is doubled by the short wavelength ultraviolet light source when the air is dense. Then, after passing through the ultrafine particle filter and the long-wavelength ultraviolet light source, dust-free, sterile, and harmless clean air is provided.

  According to the present invention, the object of providing air having high oxygen content while at the same time performing air cleaning effectively has been achieved.

  As shown in FIG. 1, the circulation route of the filtered air in the air purifier of the present invention can be divided into at least three according to the usage mode. The first is a route in which air is preliminarily filtered, passed through a compression process, sterilized by irradiation with short-wavelength ultraviolet light, and then filtered and filtered with an ultrafine particle filter to obtain purified dust-free air. . Second, ozone is generated by the air that has passed through the pre-filtration and sent to the ozone generator through the oxygen generator, and the ozone is sterilized by being irradiated with a short-wavelength ultraviolet light source in a sufficiently compressed state at the same time. This is a route that doubles the effect, decomposes the ozone with a long-wavelength ultraviolet light source after fine particles are filtered, and obtains clean air. Third, pure air is added into the oxygen generator after the pre-filtered air is fed into the oxygen generator, and the oxygen is directly discharged from the nozzle to increase the oxygen content in the indoor air.

  As shown in FIGS. 2 to 5, a separating plate 11 is provided in the box 10 to separate the box into upper and lower parts. The lower part is a preliminary filtration chamber 12, and the upper part is a pressure chamber 13. . It is assumed that an air flow passage 14 that communicates from the filtration chamber 12 to the pressure chamber 13 is formed on one side of the box 10 in the separator plate 11. As shown in FIG. 3, the preliminary filtration chamber 12 is provided with an air inlet 120, and the pressure chamber 13 is provided with an air outlet 130.

  As shown in FIGS. 5 and 6, the preliminary filtration chamber 12 is provided with a lower lid 121 on a side facing the air intake port 120 provided with a net. Switching operation of the ozone generator and oxygen generator installed inside. In addition, an activated carbon filtration net 20 is provided in the upper part of the preliminary filtration chamber 12. The activated carbon filter net 20 is inserted and set in the pre-filter chamber along the substantially U-shaped guide rail 21, and is disposed between the pre-filter chamber 12 and the air flow passage 14, whereby air is released. After forcibly passing through the air inlet 120, the activated carbon filtration network 20, and the air flow passage 14, the air reaches the pressure chamber 13, and the air flows from the bottom to the top.

  In the preliminary filtration chamber 12, a backing plate 30 is provided below the activated carbon filtration net 20, and the backing plate 30 is a place where the contaminants that have fallen naturally from the activated carbon filtration net 20 are collected. When the device of the present invention is not operating, the slide rail 31 having a substantially T-shape provided at the bottom of the support plate 30 and the pre-filtration chamber 12 provided corresponding thereto are provided. A slide rail groove 32 having a substantially T-shape allows the support plate 30 to smoothly enter and exit the pre-filtration chamber 12, thereby facilitating cleaning of dirt.

  As shown in FIGS. 4, 5, and 7, the pressure chamber 13 has a front lid 131 and a rear lid 132 corresponding to each other, and the front lid 131 is extended to the preliminary filtration chamber 12, The air inlet 120 is directly installed. In the pressure chamber 13, a partition plate 41 is provided inside the air flow passage 14, and an opening 410 is provided in the center of the partition plate 41.

  The pressure chamber 13 is provided with a compression unit 42 inside the partition plate 41, and the compression unit 42 has a motor 421 fixed on a motor base 420 provided inside the partition plate 41, A fan 422 is provided on the central axis 421. The fan 422 is located exactly at the opening 410 of the partition plate 41, and the fan 422 smoothly pressurizes the air through the opening 410 and sends the air into the pressure chamber 13 to keep the air in the pressure chamber 13 constant. The partition plate 41 is provided with a protective protection net 411 outside the opening 410.

The pressure chamber 13 is provided with an ultrafine particle filter (ULPA) 43 at an appropriate distance from the compression unit 42, and a blocking plate 133 is provided so as to protrude from the inner periphery of the inner wall of the pressure chamber 13. The blocking plate 133 is provided with four bolts 134 toward the rear lid 132,
Further, each of the bolts 134 pierces a pressure control plate 135 and fixes the pressure control plate 135 with a nut. The pressure control plate 135 controls the pressure plate installation part 430 of the ultrafine particle filter 43, and the ultrafine particle filter 43 is tightly fixed on the blocking plate 133. In this manner, a pressurizing chamber 44 is formed between the ultrafine particle filter 43, the partition plate 41, and the compression unit 42, and the pressurizing chamber 44 forcibly sends air into the ultrafine particle filter 43. As a result, only air having a diameter of 0.1 μm or less is present in the air after filtration, which has a high filtration rate of 99.9999%.

A short wavelength ultraviolet light source 45 is provided above the pressurizing chamber 44, and a window 450 is provided at a position corresponding to the box 10. As shown in FIG. 8, when the compression unit 42 is operating, the air is forced to reach the pressurizing chamber 44 from the activated carbon filtration network 20, and the air is several times higher in the pressurizing chamber 44. It becomes a high-density state, strengthens the sterilizing effect of the short-wavelength ultraviolet light source 44, and further, the ultrafine particle filter (ULPA) 43 filters particles having a diameter of 0.1 μm or more in the air, and passes through the upper branch path 136. Clean dust-free and sterile air is output from the air outlet 130 at the upper end of the box 10.
The sterilization effect in the present invention is that the photocatalyst is simultaneously applied to the pressurizing chamber 44 or the air outlet 130 or the air inlet 120, which is irradiated with the short wavelength ultraviolet light source 45, so that all harmful molecules are decomposed. It is supposed to be.

  In addition, as shown in FIGS. 2 and 4, in the present invention, an ozone generator 51 and an oxygen generator 52 are provided in the preliminary filtration chamber 12, and the ozone generator 51 and the oxygen generator 52 are installed in the filtration chamber. It is assumed that it is installed in the arranged case 50 and has a structure like one module. Also, as shown in FIG. 9, the ozone generator 51 can provide ozone in a form relatively less harmful to the human body because it directly supplies pure oxygen from the oxygen generator 52. By entering into 44, high-pressure sterilization having several times the effect is performed in combination with the short-wavelength ultraviolet light source 45, and further, the components in the air are decomposed by the long-wavelength ultraviolet light source 46 below the air outlet 130. So that the ozone does not harm the human body. As shown in FIG. 10, the oxygen generator 52 directly adds pure oxygen to the air reaching the pre-filtration chamber 12 or the pressurized chamber 44, and activates the pure oxygen alone to supply pure oxygen via the route 520. The air that is ejected into the room from the nozzle 521 on the box 10 and has a high oxygen concentration in the air provides a fatigue recovery effect to the human body. In addition, since the pure oxygen is released in a concentrated manner in the nozzle 521, a function such as an oxygen inhaler can be provided by using the mouth of a person or a patient who exercises vigorously close to the mouth.

  In the ozone generator 51, the oxygen generator 52 is operated by a microprocessor or a control board 60 to supply pure oxygen or ozone every hour to sterilize the room or to remove indoor air. It is used for the purpose of increasing the oxygen content, so that air can be cleaned automatically and for many purposes.
