Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

As shown in fig. 1 to 3, the present invention discloses a bubbler with a simple structure for mixing a foam-type liquid (e.g., a foam-type hand sanitizer or a foam-type detergent) with air in a ratio to generate foam. Specifically, the bubbler comprises a self-priming pump 1 and a bubbling base 2, wherein the bubbling base 2 is provided with a bubbling container 21, at least one air inlet channel 22 and at least one liquid inlet channel 23 which are connected with the bubbling container 21, the bubbling container 21 is directly or indirectly communicated with a pump inlet 11 of the self-priming pump 1, and the effective cross-sectional area S1 of the air inlet channel 22 and the effective cross-sectional area S2 of the liquid inlet channel 23 meet a preset proportion, so that air and foam type liquid are mixed and bubbled under the action of negative pressure of the pump inlet 11 of the self-priming pump 1 after entering the bubbling container 21 from the air inlet channel 22 and the liquid inlet channel 23 respectively according to the proportion to form foam. In addition, after the foam formed in the foaming container 21 is sucked into the self-priming pump 1 by the negative pressure at the pump inlet 11 of the self-priming pump 1, the foam type liquid which is not fully mixed with the air can be promoted to be further mixed with the air, and the effect of generating the foam is enhanced, so that the foam which is finally output from the pump outlet 12 of the self-priming pump 1 is more dense than the foam generated in the foaming container 21. Therefore, the utility model discloses a bubbler only needs to use a self priming pump 11 to send into air and liquid according to predetermineeing the proportion and froth in foaming container 21, and overall structure is simple and realize with low costs.

Wherein, the air inlet channel 22 and the liquid inlet channel 23 can be arranged on the bottom or the side wall of the foaming base 2, as long as the air inlet channel 22 and the liquid inlet channel 23 are respectively ensured to be connected with the foaming container 21. In one embodiment, the front end of the air inlet passage 22 is provided with an air inlet port 221, and the rear end of the air inlet passage 22 is communicated with the frothing container 21. In this case, the bubbler further includes an air inlet tube 3 inserted into the air inlet port 221, and air required for bubbling is supplied to the bubbling container 21 through the air inlet tube 3 via the air inlet passage 22.

The foaming container 21 has a foam outlet, and the foam outlet of the foaming container 21 is communicated with the pump inlet 11 of the self-priming pump 1 through a first pipeline 41, wherein the first pipeline 41 can be a flexible pipeline or a rigid pipeline, such as a rigid plastic pipe, a silicone tube or a rubber tube, as required.

Referring to fig. 4, the present invention further discloses a foam generating device, which at least comprises the above-mentioned bubbler. When in use, the liquid inlet channel 23 of the foaming base 2 is directly or indirectly communicated with the liquid container 5 containing the foam type liquid, and the air inlet channel 22 is directly or through the air inlet pipe 3 communicated with the outside air. For example, the foaming base 2 is directly placed in the liquid container 5 containing the foam type liquid, so that the liquid inlet channel 23 is directly communicated with the foam type liquid in the liquid container 5, the front end of the air inlet channel 22 is provided with the air inlet pipe 3, the upper tail end of the air inlet pipe 3 is exposed out of the liquid container 5, and the external air can enter the foaming container 21 through the air inlet pipe 3 and the air inlet channel 22. Under the negative pressure of the pump inlet 11 of the self-priming pump 1, air and foam type liquid are supplied to the foaming container 21 in a preset proportion, foam is formed under the negative pressure, finally the foam is further fully reacted when passing through the self-priming pump 1, and finally dense foam is output from the pump outlet 12 of the self-priming pump 1.

In a preferred embodiment, the foam generating device further comprises a foam refiner 5, the foam refiner 5 is connected to the pump outlet 12 of the self-priming pump 1 through a second pipeline 42, and the foam output from the pump outlet 12 of the self-priming pump 1 is further refined through the foam refiner 5, so that the foam is more delicate and fine to meet the requirement of high-standard foam generation.

Specifically, as shown in fig. 5 and 6, the foam refining device includes a feeding nozzle 51, a foam enhancing portion 52 and a foam output portion 55 connected in sequence, wherein a feeding channel 511 is arranged in the feeding nozzle 51, a foam reaction chamber 521 is arranged in the foam enhancing portion 52, a foam output channel 551 is arranged in the foam output portion 55, the feeding channel 511 is communicated with the foam reaction chamber 521, at least one layer of uniform mesh 53 is arranged between the feeding channel 511 and the foam reaction chamber 521, the foam reaction chamber 521 is communicated with the foam output channel 551, and at least one layer of foam enhancing mesh 54 is arranged between the foam reaction chamber 521 and the foam output channel 551. Wherein, the uniform net 53 and the foam reinforcing net 54 are fine-mesh screens, a plurality of micron-sized fine holes are uniformly distributed on the fine-mesh screens, and the foam is refined for the first time and refined for the second time through the uniform net 53 and the foam reinforcing net 54 respectively, so that the foam finally sprayed out from the foam output part 55 is fine and smooth.

Preferably, the end surface of the first end of the supply passage 511 is closed and the second end is communicated with the foam reaction chamber 521, and the sidewall of the supply nozzle 51 is opened with at least one pair of convection holes 512 oppositely arranged, and the convection holes 512 are communicated with the supply passage 511. Convection holes 512 are preferably provided on the sidewall of the supply nozzle 51 and communicate with the first end of the supply passage 511. The gas-liquid mixture enters the feed passage 511 from the convection hole 512 in a manner of convection impact, which helps to further mix the gas and the liquid to facilitate the generation of foam. Then, the gas-liquid mixture enters the foam reaction chamber 521 through the uniform mesh 53, and a plurality of micron-sized pores are arranged on the uniform mesh 53, so that fine foam is generated when the gas-liquid mixture passes through the uniform mesh 53; and then secondarily refining the foam through the foam-reinforcing net 54 again, so that the foam finally discharged from the foam discharging part 55 is more delicate.

Preferably, the inner diameter of the feed passage 511 is set gradually larger from the first end to the second end, so that the feed passage 511 has a flared shape gradually larger from the first end to the second end as a whole. The advantage of this configuration of the supply passage 511 is that, as the gas-liquid mixture moves from the convection hole 512 into the first end of the supply passage 511 toward the foam reaction chamber 521, the inner diameter of the supply passage 511 becomes larger and larger to provide more space for further mixing of the gas and the liquid to enhance the generation of foam.

Preferably, the first end of foam reaction chamber 521 is in communication with the second end of feed passage 511, the second end of foam reaction chamber 521 is in communication with foam output passage 551, and the inner diameter of foam reaction chamber 521 gradually decreases from the first end to the second end, i.e., foam reaction chamber 521 converges from the first end toward the second end, so that foam reaction chamber 521 has a closed-horn shape as a whole. The foam entering the foam reaction chamber 521 through the uniform net 53 is gradually reduced in inner diameter during the process of moving from the first end to the second end of the foam reaction chamber 521, so that the foam is extruded to reduce gaps possibly existing between the foam, the foam is more dense, and finally the foam extruded through the foam reinforcing net 54 is more dense and finer. It can be seen that the supply passage 511 is matched with the foam reaction chamber 521, so that the foam has a gradually increasing space to facilitate the gas and liquid to fully react to produce foam, and then the foam is squeezed in a gradually narrowing space to make the foam more compact, and finally the foam becomes more fine and smooth under the dual actions of the uniform net 53 and the foam enhancing net 54.

In addition, the foam discharging channels 551 of the foam discharging portion 55 are preferably non-linear, and the non-linear foam discharging channels 551 are more advantageous for further squeezing the foam during discharging to discharge continuous non-gap foam, and for manufacturing convenience, the foam discharging channels 551 are generally bent at a predetermined angle, for example, approximately L.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
