Problems solved by technology

Since the sealing mud is easy to age, and the exhaust bellows vibrates during the long-term exhaust process, air leakage (return air) occurs between the flue and the range hood pipe (at the exhaust hole), which has a great impact on the kitchen. smoke pollution

Embodiment Construction

[0017] Such as figure 1 As shown, the method for preventing air leakage between the flue and the range hood pipe includes the following steps:

[0018] 1) Preparation of the connection head (including the sealing sleeve 3 and the bellows joint 2): as figure 1 , figure 2 As shown, the connector is composed of a sealing sleeve 3 and a bellows joint 2, one end of the bellows joint is connected to one end of the sealing sleeve 3 as a whole, and an annular groove 4 is arranged outside the sealing sleeve. Depending on the shape of the reserved smoke exhaust hole 1 (that is, corresponding to the shape of the reserved smoke exhaust hole 1 on the flue, it can be circular or square), the bellows joint is circular; the corrugation of the connector ( Or thread) The corrugation (or thread) of the pipe joint can be built in ( image 3 built-in) can also be a peripheral ( figure 1 , figure 2 for peripherals);

[0019] 2) Trim the reserved smoke exhaust hole 1 on the flue (correction,...

Abstract

The invention relates to a method for preventing air leakage between a flue and a pipeline of a range hood. The method for preventing the air leakage between the flue and the pipeline of the range hood is characterized by comprising the following steps of: 1) preparation of a connector, wherein the connector consists of a sleeve gasket and a corrugated pipe joint, one end of the corrugated pipe joint and one end of the sleeve gasket are connected into a whole and annular grooves are formed outside the sleeve gasket; 2) trimming a reserved smoke vent on the flue; 3) filling a sealant or lute into the annular groove of the sleeve gasket, and sleeving the annular grooves of the sleeve gasket on the reserved smoke vent on the flue; and 4) coating the sealant or the lute on the corrugated pipe joint, screwing one end of a corrugated exhaust duct into the corrugated pipe joint and screwing the other end of the corrugated exhaust duct into a pipeline joint of the range hood. By the method, an overall combined structure with the grooved sleeve gasket and the corrugated pipe joint is adopted and the sleeve gasket is sleeved at the smoke vent, so the air leakage between the flue and the pipeline of the range hood can be prevented and smoke pollution to a kitchen can be reduced.

Description

technical field [0001] The invention relates to a method for preventing air leakage between a flue and a range hood pipe. Background technique [0002] At present, the output end of the pipe (that is, the exhaust bellows) of the range hood is directly inserted into the reserved smoke exhaust hole on the flue to communicate with the flue, and then the sealing mud is used to seal the gap between the exhaust bellows and the smoke exhaust hole. The gap is blocked. Since the sealing mud is easy to age, and the exhaust bellows vibrates during the long-term exhaust process, there will be air leakage (return air) between the flue and the range hood pipe (at the exhaust hole), which has a great impact on the kitchen. smoke pollution. Contents of the invention [0003] The purpose of the present invention is to provide a method for preventing air leakage between the flue and the range hood pipe. [0004] In order to achieve the above object, the technical solution adopted by the ...
