Description
Technical Field
The invention relates to an oxygen generator, in particular to a portable oxygen generator which can generate oxygen and synchronously release negative ions.
Background
Most of the existing oxygen generators adopt the adsorption performance of a molecular sieve, and separate nitrogen and oxygen in air by taking a large-displacement oil-free compressor as power through a physical principle to finally obtain high-concentration oxygen. Generally, a household sample making machine adopts a 220V alternating current power supply, and a portable oxygen generator adopts a 12V lithium battery direct current power supply for carrying convenience. The negative ions are known in the medical community as "air vitamins". Medical research shows that the negatively charged particles in the air can increase the oxygen content in blood, is favorable for blood oxygen transportation, absorption and utilization, and has the functions of promoting human body metabolism, improving human body immunity, enhancing human body muscle energy and regulating body function balance. The anion can purify and clean air, improve the living environment and enhance the physique of human bodies, and the standard published by the world health organization is that more than 1000 anions are contained in each cubic centimeter to be beneficial to the human bodies. Therefore, the anion function is mostly added to the existing oxygen generator, the oxygen absorption capacity of a user can be effectively improved, and the machine efficiency and the experience feeling are improved.
Most of the existing oxygenerators are added with negative ions and are realized by arranging a negative ion generator in the oxygenerator. The principle of the anion generator mainly comprises that a circuit composed of an impulse type circuit, an overvoltage current-limiting circuit, a high-voltage and low-voltage isolation circuit and the like is increased to alternating-current high voltage, then pure direct-current negative high voltage is obtained after rectification and filtering of special grade electronic materials, the direct-current negative high voltage is connected to a release tip made of metal or carbon elements, high corona is generated by the tip direct-current high voltage, a large amount of electrons (e-) are emitted at high speed, and the electrons can be immediately captured by oxygen molecules (O2) in the air, so that air anions are generated.
The built-in oxygen generator which can realize the production of negative ions while producing oxygen by the existing oxygen generator by additionally arranging the negative ion generator needs a complete set of negative ion generator, electrical elements and a power supply, so that the manufacturing difficulty and the manufacturing cost of the negative ion oxygen generator are high, the volume of the oxygen generator is increased, the household space is occupied, the carrying is not convenient, the maintenance workload is increased, and the use cost is increased.
In the prior art, an anion generating module and an internal circuit are connected through a lead and controlled by a switch to release anions, and some anion lamps are similar to an anion generator in form, and need to use alternating direct current and an electronic element circuit board, so that the problems pointed out in the background art exist.
Disclosure of Invention
Aiming at the problems of the anion oxygen generator in the prior art, the invention provides the portable oxygen generator which can synchronously release a large amount of anions while preparing oxygen by the existing oxygen generator only by changing the raw material composition of the oxygen separation column in the existing oxygen generator without additionally assembling an anion generator and related electronic elements and without power supply coordination.
The technical scheme adopted by the invention to solve the technical problem is as follows: a portable oxygen generator capable of synchronously releasing negative ions comprises a machine body and an oxygen separation column arranged in the machine body, wherein the oxygen separation column is prepared by uniformly mixing molecular sieve pellets and negative ion ceramic pellets in proportion and filling the mixture into a column tube for pressing and sealing, and the negative ion ceramic pellets consist of 40-60 wt% of kaolin, 10-20 wt% of negative ion powder and 20-40 wt% of rare earth metal oxide powder and are prepared by the following steps:
1. adding kaolin, anion powder and rare earth metal oxide powder into a ball mill according to the proportion for ball milling, adding a proper amount of water to prepare wet powder,
2. adding the powder into a ball machine for ball forming to prepare wet blank ceramic balls with the thickness of 0.2-0.4cm,
3. drying and shaping the surface of the wet green ceramic pellet, placing the wet green ceramic pellet into a kiln, heating the wet green ceramic pellet to 600-800 ℃, keeping the temperature for 10-20 hours, cooling and discharging the wet green ceramic pellet out of the kiln to prepare negative ion ceramic pellets,
4. mixing a molecular sieve pellet with the particle size of 0.2-0.4cm and a negative ion ceramic pellet with the particle size of 0.2-0.4cm according to the weight ratio of 2-4: 0.5 to 1.5, after being mixed evenly, the mixture is filled into a column tube and pressed into a column shape, and the column tube is taken out and hermetically packaged to prepare the oxygen separation column.
The negative ion powder is natural tourmaline powder or a mixture of natural tourmaline powder and rare earth oxide.
The weight ratio of the molecular sieve beads to the negative ion ceramic beads is preferably 3:1.
the rare earth metal oxide is lanthanum oxide (La) 2 0 3 ) Cerium oxide (Ce 0) 2 ) Neodymium oxide (Nb) 2 0 3 ) Yttrium oxide (Y) 2 0 3 ) And so on.
The zeolite molecular sieves, which are primarily sodium-modified (sodium type) or lithium-modified (lithium type), are commercially available from both factories and markets. The molecular sieve is a hydrate of a crystalline aluminosilicate metal salt, the main components being alumina and silica.
The invention firstly mixes kaolin, anion powder and rare earth metal oxide powder to prepare anion ceramic pellets, and then mixes the anion ceramic pellets with molecular sieve pellets to prepare the oxygen separation column. Wherein the molecular sieve plays a role in enriching and separating oxygen mainly through pressure swing adsorption. The anion ceramic pellet has certain radioactivity, so that gas molecules can generate electron transfer, and lost electrons are combined with oxygen in the air to form oxygen anions.
The invention mixes kaolin, anion powder and rare earth metal oxide to prepare anion ceramic balls with the diameter of 0.2-0.4 cm. Mixing the negative ion ceramic balls and the molecular sieve balls according to a certain proportion, filling a column tube, and pressing to prepare the oxygen separation column.
