Description

Technical Field

[0001] This utility model relates to a fan duct component for a warm air blower, belonging to the field of warm air blower technology. Background Technology

[0002] Most existing space heaters use a motor-driven impeller or fan blades, which are installed inside an air duct, typically in a volute shape. This type of space heater is generally short and thick, making it impossible to create a long, slender design. If the fan is installed at the end of a long, slender tubular air duct, it suffers from the drawback of having a larger airflow near the duct end and a smaller airflow at the far end.

[0003] Chinese Patent Publication No. CN210486092U proposes a slender tubular air duct for a heater. This air duct has a baffle plate on the inner side of the cut end, which can evenly block the air force transmitted along the wall of the tubular air duct, overcoming the defect of large air output at the near end and small air output at the far end of the slender tubular air duct. However, this heater air duct is noisy, resulting in a poor user experience. Moreover, the assembly is relatively cumbersome, with many screw-driving steps, and the overall assembly efficiency is low. Therefore, there is an urgent need for a heater air duct component to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heater duct assembly to solve the problems mentioned in the background. This utility model has a reasonable structure and is easy to operate. It can not only effectively deal with the problem of excessive noise in the heater duct, but also reduce the step of screwing, thus improving the assembly efficiency of the whole machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heater duct assembly, comprising a tubular duct, a cover plate, side fasteners, a pressurizing pipe, reinforcing components, a baffle plate, a sleeve, positioning holes, cover plate sides, sleeves, and a limiting block. A pressurizing pipe is provided at the air inlet end of the tubular duct, and multiple side fasteners are provided on both sides of the tubular duct surface.

A baffle plate is also provided within the top section of the tubular duct. Cover plate sides are provided on both the left and right sides, and multiple sleeves are mounted on the cover plate sides. Multiple sleeves are also provided at positions corresponding to the cover plate, and positioning holes are provided on the side of the sleeves. The reinforcing component includes a reinforcing plate, a fixed clamping plate, a movable clamping plate, a range groove, a threaded groove, an adjusting plate, a rotating shaft ring, a threaded block, and an adjusting spring. The reinforcing plate is connected to the top of the side fastening frame, and a fixed clamping plate is provided on the reinforcing plate. A threaded groove is provided on the top of the reinforcing plate, and the range groove is provided in the upper half of the reinforcing plate. The movable clamping plate is installed in the range groove. An adjusting spring is mounted on the support plate on the rear side of the movable clamping plate, and the adjusting spring is connected to the adjusting plate. A connecting rod is provided in the middle of the surface of the adjusting plate, and a rotating shaft ring and a threaded block are mounted on the connecting rod.

[0006] Furthermore, the threaded block is adapted to the threaded groove at the top of the reinforcing plate.

[0007] Furthermore, sound-insulating cotton is arranged on the inner wall of the cover plate.

[0008] Furthermore, the upper half of the reinforcing plate is a hollow structure, and the adjusting plate is installed inside the upper half of the reinforcing plate.

[0009] Furthermore, the positioning holes on the sleeve and the tube are fitted with limiting blocks of the same size.

[0010] Furthermore, the size of the sleeve on the side of the cover plate is adapted to the size of the sleeve on the tubular air duct, and the sleeve is also provided with a positioning hole that matches the sleeve.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a heater duct assembly. Because it adds a sleeve, positioning hole, tube, limiting block, fixed clamping plate, movable clamping plate, threaded groove, threaded block, and adjusting spring, and arranges sound insulation cotton on the inner wall of the cover plate, it helps to significantly reduce the noise in the tubular duct. The installation between the cover plate and the tubular duct is achieved by inserting the tube and the sleeve.

An adjusting spring 59 is mounted on the support plate on the rear side of the movable clamping plate 53, and the adjusting spring 59 is connected to the adjusting plate 56. A connecting rod is provided in the middle of the surface of the adjusting plate 56, and a rotating shaft ring 57 and a threaded block 58 are mounted on the connecting rod.

[0020] As the first embodiment of this utility model: the size of the sleeve 10 on the side 9 of the cover plate is adapted to the size of the sleeve 7 on the tubular air duct 1, and the sleeve 10 is also provided with a positioning hole 8 that matches the sleeve 7. A limiting block 11 of the same size is installed in the positioning hole 8 on the sleeve 7 and the sleeve 10. This design realizes the installation between the cover plate 2 and the tubular air duct 1 by inserting the sleeve 10 and the sleeve 7 together, and by using the limiting block 11 to be locked in the positioning hole 8, it helps to ensure the firmness of the sleeve 10 and the sleeve 7 when locked together.
