[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figure 1-7 As shown, this pet carrier uses an air purification device, including a box body 2 located on the carrier body 1 and a lid 3 covering the top of the box body 2. The box body 2 has a partition plate 21 that divides the interior of the box body 2 into an installation chamber and a reaction chamber for holding a biological enzyme mixture. The installation chamber contains a power source and a vacuum pump 4. The vacuum pump 4 is connected to the interior of the box body 1 via an extraction pipe 41 and to the reaction chamber via an exhaust pipe 42. The lid 3 has several exhaust holes 31 that communicate with the reaction chamber. The vacuum pump 4 extracts stale air from the box body 1 through the extraction pipe 41 and discharges the stale air into the reaction chamber through the exhaust pipe 42. The biological enzyme mixture in the reaction chamber decomposes the pollutants in the stale air, and the purified gas is discharged through the exhaust holes 31.

[0025] The bio-enzyme mixture can purify and decompose the following pollutants:

[0026] (a) Decomposition of gaseous pollutants:

[0027] 1. Nitrogen-containing gases: Ammonia is a common odorous gas. Urease and other enzymes in the biological enzyme mixture can convert ammonia into ammonium ions through a catalytic reaction, significantly reducing its content in the turbid gas. In addition, volatile organic amines such as trimethylamine can also be decomposed by biological enzymes, eliminating fishy and other odors caused by these substances.

[0028] 2. Sulfur-containing gases: Hydrogen sulfide has a rotten egg smell, and substances such as methanethiol and dimethyl disulfide emit a pungent odor. Biological enzymes can convert these sulfur-containing gases into harmless substances such as sulfates through oxidation-reduction reactions, thereby removing the odor.

[0029] 3. Volatile Organic Compounds (VOCs): Benzene, toluene, xylene, and other benzene series compounds; formaldehyde, acetaldehyde, and other aldehydes; and acetone and other ketones not only have a noticeable odor but are also harmful to the human body. The bio-enzyme mixture can gradually oxidize and decompose these VOCs through a series of complex catalytic reactions, producing harmless products such as carbon dioxide and water.

[0030] (ii) Removal of bacteria and microorganisms

[0031] 1. Bacteria: Biological enzymes can destroy the cell wall and cell membrane of bacteria, or inhibit the activity of key enzymes in bacterial cells, thereby inactivating common bacteria such as Escherichia coli and Staphylococcus aureus, preventing them from continuing to reproduce and produce odorous substances.

[0032] 2. Fungi: Biological enzymes can interfere with the metabolic processes of fungi, destroy the integrity of their cell walls, inhibit the growth of fungi such as Aspergillus niger and Penicillium, and prevent the generation of musty odors and other unpleasant smells due to fungal growth.

[0033] The advantages of bio-enzyme mixtures include: 1. Bio-enzymes possess high specificity and catalytic activity, enabling them to react rapidly with pollutants in turbid gases, significantly improving purification efficiency. Compared to traditional purification methods, they are more effective at removing odors and harmful microorganisms, achieving highly efficient purification; 2. After bio-enzymes decompose pollutants, they produce harmless substances such as water, carbon dioxide, ammonium ions, and sulfates, preventing secondary pollution and meeting environmental protection requirements; 3. Bio-enzyme mixtures can be optimized and formulated according to different turbid gas components, achieving good purification effects on various complex turbid gas compositions and having a wide range of applications; 4. The entire purification process is based on the catalytic reaction of bio-enzymes, eliminating the need for high temperatures, high pressures, or strong chemical reagents, ensuring safe and stable operation and reducing safety risks.

The circuit board 6 is inserted into the first slot 82, the bottom surface of the circuit board 6 contacts the support block 84, and the end of the circuit board 6 contacts the baffle 85, thus positioning the circuit board 6 in the mounting cavity. The third mounting seat 9 includes two oppositely arranged mounting protrusions 91, one of which is located on the partition plate 21, and the other is connected to the bottom surface of the inner wall of the box 2 through a connecting plate 92. The mounting protrusion 91 has a second guide slope 93. The electromagnetic coil 5 passes through the two mounting protrusions 91 and is located between the partition plate 21 and the connecting plate 92. The first mounting base 7, the second mounting base 8, and the third mounting base 9 respectively install and position the vacuum pump 4, the circuit board 6, and the electromagnetic coil 5 in the mounting cavity, preventing the vacuum pump 4, the circuit board 6, and the electromagnetic coil 5 from accidentally moving in the mounting cavity and causing the connection to be interrupted. At the same time, the vacuum pump 4, the circuit board 6, the electromagnetic coil 5 and the mounting cavity are detachably connected, which facilitates the maintenance and replacement of the vacuum pump 4, the circuit board 6, and the electromagnetic coil 5.

[0038] In the above technical solution: The bottom of the box body 2 is provided with a first locking block 22, and both ends of the first locking block 22 are provided with first side plates 23, making the first locking block 22 approximately U-shaped. A second locking groove 24 is formed on the opposite side of each of the two first side plates 23, and a positioning block 25 is formed on the groove wall of the second locking groove 24. A fifth guide slope 26 is formed at the end of each of the two first side plates 23. The box body 1 is provided with a second locking block 12, and both ends of the second locking block 12 are provided with second side plates 13, making the second locking block 12 approximately U-shaped.
