In washing hands, the hand sanitizer is usually applied to a part to be washed, the two parts are repeatedly kneaded until bubbling occurs, and then the part is washed clean by tap water.
There are several disadvantages to washing hands using the above method. Firstly, the use of a pressing liquid discharging mode causes difficulty in controlling the using amount of the liquid soap, the waste of the liquid soap is caused by a large pressing amount in some cases, the pressing amount is small, and the aim of sterilization cannot be fulfilled. In addition, when the hand sanitizer is manually pressed, bacteria and dirt on the hands may contaminate the sanitizer container.
Therefore, in order to overcome the defect, the hand washing machine is inoculated, because the liquid is pumped out in a foam mode by the existing hand washing machine at present, the using amount of the hand washing liquid can be saved, and because the foam pumping-out mode is adopted, compared with the mode of pumping out the raw liquid alone, the hand washing machine has more exquisite texture, and can ensure that a user obtains better experience. However, most of the prior hand washing machines are generally provided with a foam pump, i.e. a diaphragm pump, for pumping out foam, so as to mix the liquid soap with air through the foam pump, thereby achieving the purpose of foaming. However, most of the existing foam pumps often cause the phenomenon of foam removal when liquid is mixed with gas to generate foam and the foam reaches a nozzle for spraying, so that the form of the foam pumped from the nozzle is not ideal.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
Example one
A first embodiment of the present invention relates to a gas-liquid mixing device, as shown in fig. 1 and 2, including: the gas-liquid separation device comprises a liquid inlet channel 11, a gas inlet channel 12, a gas-liquid mixing cavity 13 and a separation assembly 14.
As shown in fig. 1 and fig. 2, the liquid inlet channel 11 has a liquid inlet end 111 and a liquid outlet end 112, and the liquid inlet end 111 is used for connecting with a liquid supply end 21 of a liquid pumping mechanism 2 of the hand washing machine. Secondly, the air inlet passage 12 has an air inlet end 121 and an air outlet end 122, and the air inlet end 121 is used for connecting with the air supply end 22 of the liquid pumping mechanism 2 of the hand washing machine.
In addition, in the present embodiment, as shown in fig. 1, the gas-liquid mixing chamber 13 has an inlet side 131 and an outlet side 132, and the inlet side 131 is respectively communicated with the liquid outlet end 112 of the liquid inlet channel 11 and the gas outlet end 122 of the gas inlet channel 12, and the outlet side 132 is used for being communicated with the gas-liquid conveying chamber 31 of the nozzle device 3 of the hand washing machine.
Finally, in the present embodiment, as shown in fig. 1, the dispersion unit 14 is provided in the gas-liquid mixing chamber 13 for dispersing the liquid medium introduced into the gas-liquid mixing chamber 13.
As can be seen from the above, since the gas-liquid mixing device 1 of the present embodiment includes the liquid inlet channel 11, the gas inlet channel 12, the gas-liquid mixing cavity 13 and the dispersing assembly 14, and the inlet side 131 of the gas-liquid mixing cavity 13 is connected to the liquid outlet end 112 of the liquid inlet channel 11 and the gas outlet end 122 of the gas inlet channel 12, respectively, the liquid medium and the gas medium pumped out from the liquid pumping mechanism 2 can enter the gas-liquid mixing cavity 13 through the liquid inlet channel 11 and the gas inlet channel 12, and mix in the gas-liquid mixing cavity 13, thereby effectively avoiding the phenomenon of defoaming during transportation caused by mixing of the gas medium and the liquid medium in the liquid pumping mechanism 2. In addition, the liquid medium entering the gas-liquid mixing chamber 13 can be dispersed by the dispersing component 14, and the large-particle liquid medium is dispersed into small particles, so that the liquid medium can be better mixed with the gas medium, and finer foam can be generated.
Specifically, in the present embodiment, as shown in fig. 1, the dispersing unit 14 includes: at least one distribution layer 141 of the filtration pores 14111 is distributed. Wherein, when the dispersion layer 141 is provided with a plurality of layers, the dispersion layers 141 are sequentially provided in a direction from the inlet side 131 to the outlet side 132. In practical application, the multi-dispersion of the liquid medium can be realized through the multi-dispersion layer 141, so that the liquid medium can be better mixed with the gas medium, and finer foam can be generated.
When the dispersion layers 141 are provided in a plurality of layers, as shown in fig. 3, the mesh number of the filter holes 14111 in each dispersion layer 141 gradually increases in the direction from the inlet side 131 to the outlet side 132 of the gas-liquid mixing chamber 13, for example: the mesh number of the filter holes on the dispersion layer 141 closest to the inlet side 131 is twenty meshes, and the mesh number of the filter holes 14111 on each dispersion layer 141 gradually increases in a ten-mesh number in a direction from the inlet side 131 to the outlet side 132. Therefore, in practical application, the liquid medium can be dispersed through the dispersion layer 141 with a small number of filter holes 14111, and simultaneously the flow rate of the liquid medium and the gas medium when the liquid medium and the gas medium pass through the gas-liquid mixing chamber 13 can be controlled, and the liquid medium can be finely dispersed through the dispersion layer 141 with a large number of filter holes 14111, so that the liquid medium can be dispersed into smaller particles and can be better mixed with the gas medium, and finer foam can be generated.
In addition, it is worth mentioning that, when the dispersion layer 141 has a plurality of layers, the shapes of the filter pores distributed on each dispersion layer 141 are the same. However, as an alternative, in some embodiments, the shape of each of the filter holes 14111 distributed on at least one of the dispersion layers 141 is different from the shape of each of the filter holes 14111 distributed on the other dispersion layers 141. It is thus found that the dispersion of the liquid medium by the respective dispersion layers 141 can be further facilitated by the dispersion layers 141 having the different shapes of the filter holes 14111. For example, it is preferable that the shapes of the filtering holes 14111 distributed on any two adjacent dispersion layers 141 are set to be different, so that the liquid medium can be dispersed into smaller particles by the two dispersion layers 141 having the filtering holes 14111 of different shapes when the liquid medium passes through the two dispersion layers 141.
Furthermore, as shown in fig. 3, the dispersion layer 141 in the dispersion assembly 14 is, in some embodiments, detachably disposed in the gas-liquid mixing chamber 13, so that a user can replace the dispersion layer 141 periodically, and the dispersion layer 141 is prevented from affecting the permeability of the liquid medium and the gas medium in the gas-liquid mixing chamber 13 due to the occurrence of blockage. In order to detachably mount the dispersion member 14 in the gas-liquid mixing chamber 13, in some embodiments, as shown in fig. 3, the dispersion layer 141 includes: a fixing ring 1412 and a filter net 1411 distributed on the filter holes 14111, wherein, as shown in fig. 4, the fixing ring 1412 has an inner annular surface 14121 and an outer annular surface 14122 opposite to the inner annular surface 14121, meanwhile, the filter net 1411 is connected to the inner annular surface 14121 of the fixing ring 1412, and the fixing ring 14121 is detachably connected to the inner wall of the gas-liquid mixing chamber 13. For example, as shown in fig. 3, a ring-shaped slot 133 that can be engaged by a fixing ring may be disposed on an inner wall of the gas-liquid mixing chamber 13, and the fixing ring 14121 may be engaged and fixed by the ring-shaped slot 133, so as to detachably mount the dispersion layer 141 in the gas-liquid mixing chamber 13.
As shown in fig. 1, the gas-liquid mixing device 1 of the present embodiment further includes: a liquid inlet line 15 and an air inlet line 16. The liquid inlet pipe 15 is connected to the liquid outlet end 112 of the liquid inlet channel 11 and the inlet side 131 of the gas-liquid mixing chamber 13, and the gas inlet pipe 16 is connected to the gas outlet end 122 of the gas inlet channel 12 and the inlet side 131 of the gas-liquid mixing chamber 13. By means of the liquid inlet pipeline 15 and the gas inlet pipeline 16, the liquid medium output from the liquid outlet end 112 of the liquid inlet channel 11 and the gas medium output from the gas outlet end 122 of the gas inlet channel 12 can be sent into the gas-liquid mixing cavity 13, so that the liquid medium and the gas medium can be mixed in the gas-liquid mixing cavity.
Example two
A second embodiment of the utility model relates to a hand-washing machine, as shown in fig. 5, comprising: the gas-liquid mixing device 1, the liquid pumping mechanism 2, and the nozzle device 3 according to the first embodiment.
Specifically, in the present embodiment, as shown in fig. 6, the liquid pumping mechanism 2 has a liquid supply end 21, a gas supply end 22, a liquid delivery end 23, and a gas delivery end 24. The liquid supply end 21 is connected with the liquid inlet end 111 of the liquid inlet channel 11, the gas supply end 22 is connected with the gas inlet end 121 of the gas inlet channel 12, the liquid delivery end 23 is externally connected with the liquid storage container 4, and the gas delivery end 24 is communicated with the atmosphere. Next, the nozzle device 3 has a gas-liquid delivery chamber 31, and the gas-liquid delivery chamber 31 communicates with an outlet side 132 of the gas-liquid mixing chamber 13.
In practical application, when the liquid pumping mechanism 2 works, the liquid medium can be pumped from the liquid storage container 4 through the liquid conveying end 23, external atmosphere is sucked through the gas conveying end 24, the pumped liquid medium is pumped into the liquid inlet channel 11 through the liquid supply end 21, the sucked gas medium is pumped out to the gas inlet channel 12 through the gas supply end 22, the liquid inlet channel 11 and the gas inlet channel 12 can continue to respectively feed the liquid medium and the gas medium into the gas-liquid mixing cavity 13 under the driving force of the liquid pumping mechanism 2, and the liquid medium is dispersed by the dispersing assembly 14 in the gas-liquid mixing cavity 13, so that the liquid medium can be fully mixed with the gas medium, and foam is generated. Finally, the mixed foam medium can be fed into the gas-liquid delivery chamber 31 of the nozzle device 3 and the spraying is completed.
It can be seen from the above that, since the gas-liquid medium and the liquid medium are mixed in the gas-liquid mixing chamber 13, the mixed medium can be directly sent into the gas-liquid conveying chamber 31 of the nozzle device 3, and thus the phenomenon of defoaming during the conveying process caused by the mixing of the gas medium and the liquid medium in the liquid pumping mechanism 2 is effectively avoided. In addition, the liquid medium entering the gas-liquid mixing chamber 13 can be dispersed by the dispersing component 14, and the large-particle liquid medium is dispersed into small particles, so that the liquid medium can be better mixed with the gas medium, and finer foam can be generated.
