[0058] For the air intake process: when the air bin is stretched and the volume increases, the external gas first enters the first air intake hole 103 through the air inlet port 101 and the connecting groove 102, and then passes through the second air intake hole 301, the air intake hole on the second stop plate 4 and the air intake valve sheet in turn, and then enters the air bin.

[0061] Regarding the liquid inlet process: when the liquid bin is stretched and the volume increases, the external liquid first enters the liquid inlet groove 302 through the liquid inlet port 401, and then passes through the liquid inlet through hole and the liquid inlet valve plate on the second stop plate 4 in sequence before entering the liquid bin.

[0062] Furthermore, the foaming device 3 has a first side 316 and a second side 317 that are arranged opposite to each other, the first side 316 is a side of the foaming device 3 close to the first stop plate 1 , and the second side 317 is a side of the foaming device 3 close to the second stop plate 4 .

[0063] Furthermore, a first air outlet hole 303 is provided on the foaming device 3, and the first air outlet hole 303 is located in an air collecting groove, and the air collecting groove is located on the second side 317 of the foaming device 3. The air collecting groove is arranged corresponding to the air outlet valve plate, and the second stop plate 4 is provided with air outlet holes corresponding one to one with the air outlet valve plate, and the air collecting groove is connected with the air outlet valve plate through the air outlet holes.

[0064] Regarding the gas outlet process: when the gas bin is compressed and the volume is reduced, the gas outlet valve plate opens, and the gas in the gas bin enters the gas collecting groove through the gas outlet valve plate and the gas outlet holes on the second stop plate 4, and then passes through the first gas outlet hole 303 to reach the first side 316 of the second stop plate 4.

[0065] Furthermore, the second stop plate 4 is also provided with a second air outlet 304 connected with the first side 316 of the first air outlet 303, and a one-way valve is provided on the second air outlet 304, through which the gas can flow from the first side 316 of the second air outlet 304 to the second side 317 of the second air outlet 304, and the second side 317 of the second air outlet 304 is connected with the second side 317 of the first sub-chamber 305.

[0066] Furthermore, the first sub-chamber 305 is arranged corresponding to the liquid outlet valve plate, and the second stop plate 4 is provided with liquid outlet through holes corresponding one to one to the liquid outlet valve plate, so that the liquid outlet valve plate is connected to the first sub-chamber 305.

[0067] For the liquid discharge process: when the liquid tank is compressed and the volume is reduced, the liquid discharge valve plate opens, and the liquid in the liquid tank enters the second side 317 of the first sub-chamber 305 through the liquid discharge valve plate and the liquid discharge hole on the second stop plate 4, and mixes with the gas discharged by the diaphragm pump.

[0068] Furthermore, a second stop plate 4 and a valve seat 6 are respectively provided on both sides of the valve plate 5, and the two side surfaces of the valve plate 5 are respectively tightly fitted with the second stop plate 4 and the valve seat 6 located on both sides thereof, and a plurality of through holes are provided on the valve plate 5, and the liquid outlet valve plate and the gas outlet valve plate are located in the through holes, and on the side close to the valve seat 6, the liquid outlet valve plate and the gas outlet valve plate are in the same plane as the valve plate 5, and on the side close to the second stop plate 4, the liquid outlet valve plate and the gas outlet valve plate are recessed in the valve plate 5, so that the liquid outlet valve plate and the gas outlet valve plate can only deflect toward the side close to the second stop plate 4 to open the through hole in one direction, so that the gas and liquid in the diaphragm compartment of the diaphragm 7 can pass through the liquid outlet valve plate and the gas outlet valve plate from the diaphragm 7 respectively. The liquid is discharged from the diaphragm chamber of the diaphragm 7. A check valve 12 is arranged on the side of the liquid outlet valve plate close to the valve seat 6. The check valve 12 is a spherical ball. A liquid outlet hole is arranged on the valve seat 6. The check valve 12 is at least partially located in the liquid outlet hole. When the liquid outlet valve plate is in a natural state and has not been deflected, the check valve 12 can block the liquid outlet hole so that the liquid outlet hole is in a blocked state to prevent the liquid in the diaphragm chamber of the diaphragm 7 from seeping out or the discharged liquid from flowing back. When the liquid outlet valve plate is deflected to the side close to the second stop plate 4 under the action of the pressure difference on both sides, the check valve 12 moves out of the liquid outlet hole so that the liquid outlet hole is in a connected state, so that the liquid in the diaphragm chamber of the diaphragm 7 can be discharged.

[0069] Similarly, the liquid inlet valve plate and the air inlet valve plate are located in the through hole on the valve plate 5. On the side close to the valve seat 6, the liquid inlet valve plate and the air inlet valve plate are recessed in the valve plate 5. On the side close to the second stop plate 4, the liquid inlet valve plate and the air inlet valve plate are in the same plane as the valve plate 5, so that the liquid inlet valve plate and the air inlet valve plate can only deflect to the side close to the valve seat 6 to open the through hole in one direction, so that external gas and liquid can enter the diaphragm chamber of the diaphragm 7 through the liquid inlet valve plate and the air inlet valve plate respectively.

[0070] Furthermore, the foaming device 3 forms an internal hollow chamber through the first stop plate 1 and the second stop plate 4 located on both sides thereof, the chamber is connected with the liquid outlet valve plate and the air outlet valve plate, and the chamber is also provided with a foam discharge port 312. A plurality of sub-chambers are arranged in parallel in the chamber, each sub-chamber is provided with a filter screen, and a foam channel is provided between each sub-chamber and the adjacent sub-chamber. After the liquid in the liquid tank and the gas in the gas tank enter the chamber through the liquid outlet valve plate and the air outlet valve plate respectively, they can pass through the filter screen in each sub-chamber in turn through the foam channel.

[0071] Since the chamber is provided with a plurality of sub-chambers in parallel, and each sub-chamber is provided with a filter screen, the present application changes the arrangement of the filter screens, changes the direction of the foam, and allows the foam to pass through each filter screen in sequence, so that the volume of the foaming device 3 can be very small, thereby increasing the application range of the foaming device 3. In addition, the foaming device 3 also has the advantages of simple structure and convenient preparation.

[0072] Furthermore, the foaming device 3 includes a closed side wall and a plurality of filter screens arranged in parallel inside the side wall. The first stop plate 1 and the second stop plate 4 are respectively arranged on both sides of the side wall. An internal hollow chamber is formed by the first stop plate 1, the second stop plate 4 and the side wall. The filter screens are separated by a partition plate 318. The two end surfaces of the partition plate 318 are respectively sealed and connected to the first stop plate 1 and the second stop plate 4, thereby dividing the chamber into a plurality of sub-chambers arranged in parallel.

[0073] Furthermore, a foam channel is provided between each sub-chamber and an adjacent sub-chamber. According to the order in which liquid and gas flow through each sub-chamber, the foam channels are alternately arranged on both sides of the filter screen, so that the liquid and gas can pass through the filter screen in each sub-chamber in turn through the foam channel.

[0074] Preferably, the foam channel is arranged on the partition 318 between two adjacent sub-chambers, and the foam channel includes a first foam channel, a second foam channel, a third foam channel and a fourth foam channel. The first foam channel is a barrier arranged between two adjacent sub-chambers, and the height of the barrier is lower than the partition 318, so that the barrier is not connected to the first stop plate 1 or the second stop plate 4, thereby forming a first foam channel for foam to flow through. The second foam channel is a through hole arranged on the partition 318 between adjacent sub-chambers. The third foam channel is a notch arranged on the partition 318 between adjacent sub-chambers. The fourth foam channel is formed by removing the partition 318 arranged between adjacent sub-chambers.

[0075] Preferably, in the same foaming device 3, the foam channel may be one of the first foam channel, the second foam channel, the third foam channel and the fourth foam channel, or may be several of the first foam channel, the second foam channel, the third foam channel and the fourth foam channel.

[0076] Specifically, the number of the sub-chambers is recorded as n, and the sub-chambers are recorded as the first sub-chamber 305, the second sub-chamber 307, the third sub-chamber 308...the mth sub-chamber, the m+1th sub-chamber...the nth sub-chamber, wherein n≥2, 1≤m<n. Correspondingly, the first sub-chamber 305 is provided with a first filter screen, the second sub-chamber 307 is provided with a second filter screen, ..., the nth sub-chamber is provided with an nth filter screen, and the filter screen is located in the middle of the partition 318, and each sub-chamber is divided into two parts. According to the division of the two sides of the foaming device 3, the side of each sub-chamber close to the first stop plate 1 is recorded as the first side 316, and the side of each sub-chamber close to the second stop plate 4 is recorded as the second side 317.

[0077] If the liquid and gas enter the first sub-chamber 305 from the second side 317 of the first sub-chamber 305, the foam channel between the first sub-chamber 305 and the second sub-chamber 307 is set on the first side of the partition 318 between the first sub-chamber 305 and the second sub-chamber 307. After the liquid and gas enter the first sub-chamber 305, they will pass through the first filter net and enter the second sub-chamber 307 through the foam channel between the first sub-chamber 305 and the second sub-chamber 307 to initially form foam; then pass through the second filter net and enter the third sub-chamber 308 through the foam channel set between the second sub-chamber 307 and the third sub-chamber 308. The foam channel between the second sub-chamber 307 and the third sub-chamber 308 is located on the first side 316 of the partition 318 between the second sub-chamber 307 and the third sub-chamber 308, and continue to foam, ..., and in this way, pass through the first filter net, the second filter net, ... and the nth filter net in sequence, and finally complete the foaming process and be discharged from the foam discharge port 312.

[0078] Preferably, the number of the sub-chambers is 2 to 10.

[0079] The first stop plate 1 and the second stop plate 4 are arranged in parallel on both sides of the side wall, and the side wall, the first stop plate 1 and the second stop plate 4 form an internal hollow chamber, and the filter screen in each sub-chamber can be arranged in parallel with the first stop plate 1 or the second stop plate 4, or can be arranged obliquely between the first stop plate 1 or the second stop plate 4. The first stop plate 1 and the second stop plate 4 can be prepared separately from the side wall and assembled together, or can be prepared by integral molding.

[0080] Preferably, the filter screen is arranged in parallel with the first stop plate 1 or the second stop plate 4 .

[0081] Preferably, as attached Figure 6-7As shown, four filter screens are arranged in parallel in the chamber, namely the first filter screen, the second filter screen, the third filter screen and the fourth filter screen, and each filter screen is separated by a partition 318 to form four sub-chambers, namely the first sub-chamber 305, the second sub-chamber 307, the third sub-chamber 308 and the fourth sub-chamber 310.

[0082] When the volume of the liquid bin is reduced, the liquid in the liquid bin will sequentially pass through the check valve 12, the valve seat 6, the liquid outlet valve plate and the second stop plate 4 to enter the second side 317 of the first sub-chamber 305; when the volume of the gas bin is reduced, the gas in the gas bin will sequentially pass through the valve seat 6, the gas outlet valve plate and the second stop plate 4 to enter the second side 317 of the first gas outlet hole 303, then pass through the first gas outlet hole 303 and enter the first side 316 of the second gas outlet hole 304, and then pass through the second gas outlet hole 304 and enter the second side 317 of the first sub-chamber 305, where the liquid and gas meet and are preliminarily mixed to form foam;

[0083] In order to facilitate the correspondence with Example 1, special explanation is required. The second side 317 of the first sub-chamber 305 is the gas-liquid mixing tank 21 in Example 1; all sub-chambers except the second side 317 of the first sub-chamber 305 are the foaming chambers in Example 1, and the filter holes and foam channels of the filter are the foaming channels in Example 1.

[0084] Furthermore, under the action of the pressure difference, the foam on the second side 317 of the first sub-chamber 305 passes through the first filter and enters the first side 316 of the first sub-chamber 305. The first side 316 of the first sub-chamber 305 is connected with the second side 317 of the second sub-chamber 307 through the first foam outlet 306, so the gas can enter the second side 317 of the second sub-chamber 307 through the first foam outlet 306, and then pass through the second filter to enter the first side 316 of the second sub-chamber 307. No partition 318 is provided between the first side 316 of the second sub-chamber 307 and the first side 316 of the third sub-chamber 308, so the first side 316 of the second sub-chamber 307 is directly connected with the first side 316 of the third sub-chamber 308, and the foam on the first side 316 of the second sub-chamber 307 can flow to the first side 316 of the third sub-chamber 308, and then pass through the third The filter screen enters the second side 317 of the third sub-chamber 308.
