Description

[0026] The baffle 100 of the pulse air flow generator is provided with the air inlet one-way valve 110 and the air outlet one-way valve 120, the two sides of the baffle 100 are covered by the cover plate 200 and the air drum membrane 300, the cover plate 200 and the air drum membrane 300 cover the area of the baffle 100 where the air inlet one-way valve 110 and the air outlet one-way valve 120 are arranged, thereby forming the air inlet cavity 400 and the air drum cavity 500, the air inlet cavity 400 is communicated with the air inlet pipe 700, the air outlet pipe 600 inserted in the cover plate 200 covers the air outlet one-way valve 120 inside, when the air drum driving assembly 800 drives the air drum membrane 300 to expand, the gas enters the air inlet cavity 400 through the air inlet pipe 700, and then enters the air drum cavity 500 through the air inlet one-way valve 110, when the air drum driving assembly 800 drives the air drum membrane 300 to contract, the gas in the air drum cavity 500 directly enters the air outlet pipe 600 after passing through the air outlet one-way valve 120, so that the air drum cavity 500 can intermittently air the air outlet pipe 600 when the air drum driving assembly 800 makes the air drum membrane 300 cycle between expansion and contraction, and therefore the pulse air flow generator can directly generate the airflow with flow fluctuation.

[0027] As shown in the figure, Figure 3 The baffle 100 can include: a hole plate 130, the air inlet hole 131 and the air outlet hole 132 are opened on the hole plate 130; the air inlet one-way valve 110 can include: an air inlet spring piece 111, which is arranged on the side of the hole plate 130 facing the air drum membrane 300 and covers the air inlet hole 131; the air outlet one-way valve 120 can include: a gasket 121, the gasket through hole 122 adapted to the air outlet pipe 600 is opened on the gasket 121, so that the pipe opening of the air outlet pipe 600 presses around the gasket through hole 122, the air outlet pipe 600 can cover the gasket through hole 122 inside the pipe, and the transition through hole 123 adapted to the air inlet hole 131 is opened; the air outlet spring piece 124 is connected with the gasket 121 and covers the air outlet hole 132 when the air outlet pipe 600 abuts against the gasket 121 and covers the gasket through hole 122 inside.

[0028] The principle of one-way air inlet and outlet of the pulse air generator is as follows. When the air drum driving assembly 800 drives the air drum membrane 300 to expand, the gas in the air inlet cavity 400 can only press the air outlet leaf 124 on the air outlet hole 132, so that the air inlet leaf 111 is pushed away through the transition hole 123 and the air inlet hole 131, and enters the air drum cavity 500. When the air drum driving assembly 800 drives the air drum membrane 300 to contract, the gas in the air drum cavity 500 can only press the air inlet leaf 111 on the air inlet hole 131, so that the air outlet leaf 124 is pushed away through the air outlet hole 132, and enters the air outlet pipe 600 through the gasket hole 122.

[0029] As shown in Figure 3 , the air inlet hole 131 can have several, so that the gas from the air inlet cavity 400 enters the air drum cavity 500 more smoothly, and the air inlet hole 131 is arranged around the air inlet leaf insertion hole 133. When the air inlet leaf 111 is inserted into the air inlet leaf insertion hole 133, it can cover each air inlet hole 131 arranged around.

[0030] As shown in Figure 3 , the air outlet leaf 124 can be arranged in the gasket hole 122 and connected with the inner wall of the gasket hole 122. When the air outlet leaf 124 is connected with the inner wall of the gasket hole 122, it can be in a depressed state, so that the gas in the air inlet cavity 400 can only press the air outlet leaf 124 on the air outlet hole 132 and cannot pass through.

[0031] As shown in Figure 2 and Figure 4 , the air drum driving assembly 800 can include a motor 810 connected with a transmission plate 820, the transmission plate 820 being connected with the air drum membrane 300, so that when the motor 810 drives the transmission plate 820 to rotate, the transmission plate 820 drives the air drum membrane 300 to cycle between expansion and contraction.

[0032] As shown in Figure 1 , the partition plate 100 can be provided with a plurality of sets of air inlet one-way valves 110 and air outlet one-way valves 120, and each air outlet one-way valve 120 is covered inside by the corresponding air outlet pipe 600 inserted in the cover plate 200, and each set of air inlet one-way valve 110 and air outlet one-way valve 120 is covered inside by the corresponding air drum membrane 300; combined Figure 4 , the center of the transmission plate 820 can be provided with a transmission rod 830, the transmission rod 830 being eccentrically connected with the motor 810; the transmission plate 820 being connected with each air drum membrane 300. In this way, one motor 810 can drive multiple air drum membranes 300 at the same time, outputting multiple flow fluctuation air flows.

[0033] The transmission plate 820 can be connected with each air drum membrane 300 as follows.

[0034] As shown in Figure 1and Figure 2 As shown, the bottom of the air-blowing membrane 300 is provided with an air-blowing membrane protrusion 310; as Figure 4 As shown, the transmission plate 820 has several insertion holes 821, and each insertion hole 821 is located on the same circular track centered on the transmission rod 830; combined with Figure 2 The bulging membrane protrusion 310 is inserted into the corresponding insertion hole 821.

[0035] like Figure 5 As shown, a pair of motors 810 can be connected in opposite directions so that both ends are provided with a plurality of air outlet pipes 600.

[0036] The intake pipe 700 passes through the partition 100 or the cover plate 200 to connect to the intake chamber 400. Figure 2 As shown, in at least one embodiment, the air intake pipe 700 passes through the partition 100.

[0037] In summary, the pulse airflow generator provided by this utility model has an inlet one-way valve 110 and an outlet one-way valve 120 on its partition 100. Both sides of the partition 100 are covered by a cover plate 200 and an air-blowing membrane 300, respectively. Both the cover plate 200 and the air-blowing membrane 300 cover the areas on the partition 100 where the inlet one-way valve 110 and the outlet one-way valve 120 are located, forming an inlet chamber 400 and an air-blowing chamber 500. The inlet chamber 400 is connected to the inlet pipe 700, and the outlet pipe 600 inserted in the cover plate 200 covers the outlet one-way valve 120. When the air-blowing is activated... When component 800 drives the expansion of the diaphragm 300, gas enters the intake chamber 400 through the intake pipe 700, and then enters the blasting chamber 500 through the intake check valve 110. When the blasting drive component 800 drives the diaphragm 300 to contract, the gas in the blasting chamber 500 enters the outlet pipe 600 directly after passing through the outlet check valve 120. In this way, when the blasting drive component 800 causes the diaphragm 300 to cycle between expansion and contraction, the blasting chamber 500 can intermittently blow air into the outlet pipe 600. Therefore, this pulse airflow generator can directly generate airflow with fluctuating flow rate.
