Fan for fuel gas heating water heater

Abstract

The invention discloses a fan for a fuel gas heating water heater in the technical field of fans. Wind output holes are uniformly formed in the left side of a shell. A shell cover is arranged on the right side of the shell. Wind input holes are uniformly formed in the shell cover. A limiting ring is arranged on the left side of an inner cavity of the shell. A motor base is arranged on the middle portion of the inner cavity of the shell. Multiple fan blades are uniformly arranged on the outer wall of an installing ring. A dustproof baffle is arranged on the right side of the inner cavity of theshell. By means of a primary filter screen of the inner cavity of the dustproof baffle, dust can be prevented from entering the inner cavity of the shell, by means of cooperation with an efficient filter screen, the dust can be isolated from entering the shell, a holding rod and a sliding block are matched with a connecting plate and bristles to clear the efficient filter screen, the situation ofblocking of the fan is prevented, and the service life of the fan is prolonged. The shell cover is rotated through a pin shaft, and the shell can be opened rapidly. By means of an elastic buckle, thedustproof baffle is disassembled from the inner cavity of the shell, periodic cleaning and maintaining are facilitated, the practical performance is improved greatly, and the use requirement is met.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a fan used for gas heating water heaters. Background technique [0002] Gas heating water heaters, as the name suggests, rely on natural gas to provide hot water and heating heat. Gas heating water heaters are a new type of equipment. During the combustion process, gas heating water heaters require the participation of air in the combustion process. However, the existing fans all have certain problems in the use process. For example, the existing fans cannot be dustproof during use, and the dust in the air can easily block the fan or the fan outlet during long-term use. The wind carries a lot of dust, which not only reduces the air quality, but also reduces the service life of the fan. At the same time, the existing fan is not easy to disassemble and repair, which greatly reduces the practical performance, resulting in the inability to meet the needs of use. We propose a fan for ga...

Problems solved by technology

[0002] As the name suggests, the gas heating water heater relies on natural gas to provide hot water and heating heat. The gas heating water heater is a newly emerging device. During the combustion process, the gas heating water heater needs the participation of air in the combustion process. Fans are needed, but there are certain problems in the use of existing fans. For example, the existing fans cannot prevent dust during use, and the dust in the air is easy to block the fan or the outlet of the fan during long-term use. The wind carries a large amount of dust, which not only reduces the air quality, but also reduces the service life of the fan. At the same time, the existing fan is not easy to disassemble and repair, which greatly reduces the practical performance and cannot meet the use requirements. Therefore, We propose a fan for gas heating water heater
