Common indoor pests such as cockroaches, flies, mosquitoes, etc. often appear in restaurants, supermarkets, bedrooms, home kitchens and other places, causing a lot of trouble to families and public places. They not only affect people's lives, but also bring harm to people's health. to threaten. Cockroaches, in particular, have strong fecundity, a wide feeding range, and are quick and difficult to catch, causing serious trouble to human life.

At present, the main methods to eliminate cockroaches include spraying drugs and cockroach traps. If the chemical cockroach killing method of spraying drugs is used for a long time, the drug resistance of cockroaches will increase, making it difficult to eliminate them later. Moreover, these cockroach drugs are highly toxic and will inevitably cause harm to human health. Existing cockroach traps generally place an attractant inside the trap and place a sticky plate at the bottom of the cockroach trap. When cockroaches are attracted by the attractant and enter the cockroach trap, they will be stuck to the sticky plate and cannot escape, thus achieving The purpose of killing cockroaches.

However, when the sticky plate is filled with cockroaches, it needs to be replaced. The attractant can be reused and does not need to be replaced frequently. Since the collection box of the existing cockroach trap is generally an integrated mechanism, the sticky plate is placed at the bottom of the cockroach trap. The bottom makes cleaning the cockroach trap and replacing the sticky plate complicated and cumbersome. You need to open the top, take out the tray with the attractant, and then take out the sticky plate from bottom to top. The entire operation is complicated and inconvenient. Replace the sticky board, and during the process of replacing the sticky board, it is easy for the attractant to scatter. Moreover, the stickiness of the sticky board will also decrease in the long-term process, and cockroaches can easily escape from the sticky board, resulting in low cockroach capture rate and poor killing effect.

Therefore, this embodiment provides a pest killing device that is easy to clean, has a high capture rate, and has a good killing effect to solve the problem that the existing cockroach traps are inconvenient to clean, easy to escape, low in catching efficiency, and have poor killing effect. The problem.

Substances break down into harmless substances. Plasma discharge is used to purify the air and has good odor removal effect. Plasma odor removal does not cause secondary pollution and is a green and environmentally friendly method.

The pest catching and killing device provided in this embodiment has the functions of trapping, disinfecting, and recycling. The interior of the pest killing device is divided into three layers of space: upper and lower.

The pest killing device provided in this embodiment has two application scenarios, one is the pest disinfecting mode, which is used to disinfect pests, and the other is the odor removal mode, which is used to purify odors. Among them, purifying odors can refer to pests. Deodorize the inside of the killing device, or deodorize the indoor ambient air.

It should be explained that in this embodiment, the odor removal mode can be selected through the function button. The principle of odor removal is as follows: pulse corona discharge superimposes a pulse voltage between two uneven electrodes. Due to the front and rear edges of the pulse voltage, It is extremely steep and has a narrow peak width. In a very short pulse time, an intense, high-frequency pulse corona discharge occurs around the corona electrode, producing high-concentration plasma. Plasma contains a large number of high-energy electrons, ions, excited molecules and free radicals. The energy of these active particles is higher than the bond energy of gas molecules. They frequently collide with volatile organic molecules, causing bond breaking and dissociation of hydrocarbon molecules. Instead, many short carbon chain free radical fragments are formed. These free radical fragments react with each other, and some of them generate small molecular hydrocarbons with short carbon chains and degrade, while the other part may form long carbon chain hydrocarbon molecules and polymerize. When oxygen is present in the reaction, the oxygen molecules react with the free radical fragments generated after the hydrocarbons break their bonds and dissociate, oxidizing them into carbon oxides to oxidatively decompose the hydrocarbons. In addition, oxygen molecules collide with high-energy electrons in the plasma to produce excited oxygen molecules and atoms. These strongly oxidizing particle hydrocarbon molecules and their dissociated free radical fragments react to oxidize and decompose volatile hydrocarbons. At the same time, high-energy electrons directly collide with hydrocarbon molecules, opening the chemical bonds of hydrocarbon molecules, thereby directly decomposing volatile organic compounds into harmless molecules to achieve the purpose of removing odors.
