Multifunctional intelligent pipeline blower

Abstract

The invention discloses a multifunctional intelligent pipeline blower. The multifunctional intelligent pipeline blower comprises an air inlet pipeline, a working shell and an air outlet pipeline. Theair inlet pipeline and the air outlet pipeline communicate with the left and right sidewalls of the working shell correspondingly. The outer end of the air inlet pipeline is provided with a netted cover plate, an air inlet and a reset spring arranged at the air inlet and abutting against the cover plate. The cover plate can cover the air inlet. A filter screen is arranged at the inner end of the air inlet pipeline. The filter screen is fixedly connected with the inner wall of the air inlet pipeline in the circumferential direction. The multifunctional intelligent pipeline blower further comprises an electric cylinder. A telescopic shaft of the electric cylinder is connected with one end of a pull rope, and the other end of the pull rope is connected with the inner surface of the cover plate. An infrared sensor array is arranged in the center of the filter screen. The inner wall of the air outlet pipeline is provided with a temperature sensor and a humidity sensor. The working shell comprises a shell body and a controller arranged on the shell body. The shell body comprises an inner wall and an outer wall. An electric heating resistance wire and a sound reduction board are distributed in a cavity between the inner wall and the outer wall in sequence. The multifunctional intelligent pipeline blower is good in automation level, capable of improving the ventilation environment, controllable in temperature and humidity and good in data observation effect.

Description

technical field [0001] The invention relates to a duct ventilation device, in particular to a multifunctional intelligent duct fan. Background technique [0002] Duct fan is a kind of ventilation device, which is generally installed in the duct or placed in the wall, and ventilates the area connected to the duct or wall by transmitting the air in the duct or wall. The duct fan includes a metal plate shell with an air inlet and an air outlet, and also includes a motor, which is installed in the shell through a metal fixed cover. At present, the existing pipeline fan is lack of intelligence, and the function is relatively simple, which does not meet the needs of the society. [0003] The Chinese Patent Publication No. CN 204949893 U discloses an intelligent temperature-regulating hair dryer. Its working principle is roughly the same as that of duct ventilation. The impeller and the motor are installed at the joint, the impeller is installed on the driving rotor of the motor,...

AI Technical Summary

Problems solved by technology

The temperature sensor, single-chip microcomputer, refrigeration module and heating module form a temperature closed-loop control system, which keeps the temperature of the blown air above and below the target temperature, thereby achieving the purpose of intelligent temperature regulation, but the function is single and the noise is large

[0004] In order to solve the problem of high noise when the existing ducted fan works, the Chinese Patent Publication No. CN 206903904 U discloses a silent ducted fan. The silent ducted fan includes a casing, an air inlet, an air outlet, and a The inner impeller and the motor that drives the impeller rotate, and the air inlet and outlet are arranged on the opposite sides of the casing; the casing includes an inner wall and an outer wall, and there is a cavity for accommodating sound-absorbing materials between the inner wall and the outer wall; the inner wall and the outer wall are distributed by It is made of a sound-absorbing board with several sound-absorbing holes; a layer of fine sound-absorbing material is attached to the outer wall in the cavity, and a layer of coarse sound-absorbing material is attached to the inner wall; at least one layer of sound-absorbing material is placed between the fine sound-absorbing material and the coarse sound-absorbing material A sound-absorbing corrugated plate with a number of sound-absorbing holes; a positioning rod for fixing the sound-absorbing corrugated plate is provided at the crest or trough of the sound-absorbing wave plate in the cavity, which has a good noise reduction effect, but only has ventilation and noise reduction functions. The function is still relatively single, not intelligent enough

[0005] Due to the special installation location of the ducted fan, real-time monitoring of its quality cannot be carried out, and the working environment of the ducted fan is relatively harsh. Small animals such as mice will enter the air inlet of the ducted fan, which may easily cause duct blockage, hinder ventilation, and seriously It will lead to electrical failure of the ducted fan, and there is a potential safety hazard. Therefore, it is necessary to improve the intelligence of the existing ducted fan and realize the safe and reliable operation of the ducted fan.
