Technical Field

[0001] This utility model belongs to the field of kitchen fume purification technology, specifically relating to a kitchen fume purification device that prevents the exhaust pipe from clogging. Background Technology

[0002] The kitchen is the most polluted space in the home, with two main sources of pollution: first, harmful gases such as carbon monoxide, carbon dioxide, sulfur dioxide, and nitrogen oxides released from cooking fires using coal, natural gas, or liquefied petroleum gas; and second, cooking fumes produced during cooking. The main components of cooking fumes are aldehydes, ketones, hydrocarbons, fatty acids, alcohols, aromatic compounds, ketones, lactones, and heterocyclic compounds. Cooking fumes are most harmful to women's skin. Fume particles adhere to women's skin, causing clogged pores and accelerating skin aging. Furthermore, cooking fumes entering the respiratory tract pose a threat to health. Fume purifiers are devices that treat cooking fumes. They are mainly used to purify and treat low-altitude emissions of cooking fumes from the kitchen. In modern kitchens, almost every household has a fume purifier installed to remove cooking fumes and purify low-altitude emissions.

[0003] The existing exhaust pipes of rural range hoods are open at the end. In colder weather, due to the high temperature of the range hood pipes, birds will build nests inside the outer pipes of the range hood in winter, blocking them and affecting the exhaust effect, which can easily cause blockage of the exhaust pipes. Utility Model Content

[0004] The purpose of this utility model is to provide a kitchen fume purification device that prevents the exhaust pipe from clogging, in order to solve the problem mentioned in the background art that the end of the exhaust pipe of the existing rural range hood is set as an open opening. In cold weather, due to the high temperature of the range hood pipe, birds will build nests in the outer pipe of the range hood in winter, blocking the outer pipe of the range hood, thereby affecting the exhaust effect and easily causing the exhaust pipe to become clogged.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a range hood body and an L-shaped exhaust pipe connected to and installed on the upper surface of the range hood body. One end of the exhaust pipe is provided with an annular protective mesh plate. A support ring is provided inside the exhaust pipe. Four scrapers are installed on the right side of the support ring. One end of each scraper has an inclined surface and abuts against the inner wall of the exhaust pipe. A common movable ring is installed on one end of each of the four scrapers.
