[0022] The object, technical solutions, and advantages of the present application will become more apparent after a reading of the following detailed description together with the attached drawings.
[0023] It is to be understood that all the descriptions above are only examples for illustration only and are not intended to limit the scope of the present application.
[0024] Some embodiments of the present application provide an angle-adjustable three-way variable-diameter air duct.
[0025] In combination with Figures 1-3 As shown in the drawings, the present application provides an angle-adjustable three-way variable-diameter air duct, which comprises a three-way air duct 100 and an adjusting assembly 200 arranged on the three-way air duct 100.
[0026] The adjusting assembly 200 comprises an adjusting mechanism mounted on the three-way air duct 100, a filtering mechanism arranged on the adjusting mechanism, and a cleaning mechanism arranged on the side of the adjusting mechanism. The adjusting mechanism comprises a rotating shaft 210 inserted into the middle part of the three-way air duct 100, a motor 220 connected to the end part of the rotating shaft 210, an adjusting plate 230 symmetrically arranged in the middle part of the rotating shaft 210, and an expansion plate 280 arranged in the middle part of the three-way air duct 100. The filtering mechanism comprises a torsion spring shaft I 240 mounted on both ends of the rotating shaft 210, a filter screen plate 250 fixed on the torsion spring shaft I 240, a limiting plate 260 mounted in the three-way air duct 100 and located at the filter screen plate 250, and a limiting block 270 fixed on the limiting plate 260. By means of the adjusting assembly 200, the motor 220 can be used to drive the adjusting plate 230 to rotate and adjust the size of the shunt air volume of the three-way air duct 100, and the filter screen plate 250 can be used to filter the shunt airflow, thereby improving the functionality of the three-way air duct 100 and having high practicability.
[0027] Further, the cleaning mechanism comprises a debris discharge port 310 formed in the bottom of the extension plate 280, a torsion spring shaft two 320 installed at the bottom of the extension plate 280, a pressing plate 330 fixed to the torsion spring shaft two 320 and located below the debris discharge port 310, a sealing block 340 installed on the pressing plate 330 and located in the debris discharge port 310, a high-pressure nozzle 350 installed on the outer side of the extension plate 280, a flow divider 360 connected to the outer side of the high-pressure nozzle 350, and an air pump 370 connected to the flow divider 360 and installed on the extension plate 280. The filter screen plate 250 can be rotated into the extension plate 280 by driving the motor 220, at this time, the adjusting plate 230 is blocked between the three-way air pipe 100 and the extension plate 280, and then the air pump 370 is started. The high-pressure airflow is sprayed from the high-pressure nozzle 350 towards the filter screen plate 250, and the dust and debris left on the filter screen plate 250 are washed away. Under the impact of high pressure, the sealing block 340 is pushed to rotate the torsion spring shaft two 320, so that the debris discharge port 310 is opened to discharge the dirt, and the automatic cleaning is realized.
[0028] Specifically, the filter screen plate 250 comprises two groups symmetrically arranged with the adjusting plate 230. The two groups of filter screen plates 250 can block the two channels after flow division, so as to filter the passing air.
[0029] It should be noted that the two filter screen plates 250 are respectively connected to the torsion spring shaft one 240 at both ends of the rotating shaft 210. The torsion spring shaft one 240 can be used to drive the filter screen plate 250 to rotate when the rotating shaft 210 is driven. One group of filter screen plates 250 will always be stationary under the blockage of the limiting block 270, so as to realize the comprehensiveness of filtering, and the other flow division channel cannot be filtered, and the practicability is high.
[0030] Further, the end of the limiting plate 260 is an arc surface structure with the rotating shaft 210 as the center, which can form a seal with the filter screen plate 250 to prevent airflow from flowing between the filter screen plates 250.
[0031] On the other hand, the outer side of the bottom of the debris discharge port 310 is provided with a sealing gasket 311, which can improve the sealing between the sealing block 340 and the extension plate 280.
[0032] Further, the pressing plate 330 is provided with a through hole 331, which can prevent the debris discharged from the debris discharge port 310 from accumulating on the pressing plate 330.
[0033] The working principle and use process of the utility model are as follows: first, in the case of conventional two equal division flow division, such as Figure 1As shown, the air flow enters and is divided into two sides, the sundries in the air are filtered by the filter screen 250, when it is needed to adjust the air volume of the upper and lower two sides, the rotating shaft 210 is rotated by the motor 220 to change the inclination angle of the adjusting plate 230, at this time, the end of the filter screen 250 is always attached to the limiting plate 260 to ensure the filtering effect, when it is needed to clean the filter screen 250, the rotating shaft 210 is rotated to the position by the motor 220 Figure 3 At this time, the adjusting plate 230 is blocked between the three-way air pipe 100 and the expansion plate 280, and then the air pump 370 is started, the high-pressure air flow is sprayed from the high-pressure nozzle 350 to the filter screen 250 to wash away the dust and sundries left on the filter screen 250, under the high-pressure impact, the sealing block 340 is pushed to rotate the torsion spring shaft two 320, so that the sundries outlet 310 is opened to discharge the sundries.
[0034] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, the scope of the utility model is defined by the claims and its equivalents.
