[0025] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0026] See also Figure 1-3 The foaming device 100 includes a foamer 1 and a liquid pump 2. The foamer 1 is provided with a foaming chamber a, a first liquid inlet channel b, a second liquid inlet channel c and a liquid outlet channel d. One end of the first liquid inlet channel b is connected to the foaming chamber a, and the other end of the first liquid inlet channel b is used to connect to a water supply source. One end of the second liquid inlet channel c is connected to one side of the first liquid inlet channel b, and the other end of the second liquid inlet channel c is used to connect to a container for storing foaming liquid. The liquid outlet channel d is connected to the foaming chamber a. The liquid pump 2 is connected to the first liquid inlet channel b, and the liquid pump 2 is used to drive the water provided by the water supply source to enter the foaming chamber a through the first liquid inlet channel b at a preset flow rate.
[0027] When the foamer 1 is working, the water provided by the water supply source flows to the foaming chamber a through the first liquid inlet channel b at a preset flow rate under the action of the liquid pump 2. The local negative pressure generated when the water flows through the connecting point between the first liquid inlet channel b and the second liquid inlet channel c draws the foaming liquid in the liquid storage container into the first liquid inlet channel b through the second liquid inlet channel c. The foaming liquid and water are mixed in the first liquid inlet channel b and then enter the foaming chamber a together, and are finally sprayed out from the liquid outlet channel d.
[0028] It should be understood that the flow rate of water provided by the water supply source flowing through the first liquid inlet channel b is related to factors such as the length of the first liquid inlet channel b, the diameter of the first liquid inlet channel b, the viscosity of the water provided by the water supply source, the density of the water provided by the water supply source, and the flow rate of the liquid pump 2. In order to generate sufficient negative pressure in the first liquid inlet channel b to satisfy the need to suck the bubbling liquid into the first liquid inlet channel b, the preset flow rate of the water provided by the water supply source can be obtained by adjusting the structure of the first liquid inlet channel b, the type and performance of the liquid pump 2 according to actual conditions.
[0029] It should be noted that the foaming liquid is a liquid used to generate foam, which is usually made of a surfactant, water and a thickener. The formula and ingredients of the foaming liquid may vary according to its specific use. For example, the foaming liquid used in the toilet may be added with acidic substances (such as hydrochloric acid or citric acid) to dissolve scale and urine scale, bleach (such as sodium hypochlorite) for sterilization and bleaching, and fragrances to cover up odors, etc. according to actual needs.
[0030] In the embodiment of the present application, a first liquid inlet channel b and a second liquid inlet channel c at one end of which is connected to one side of the first liquid inlet channel b are integrated in the foamer 1, and water is driven by the liquid pump 2 to flow through the first liquid inlet channel b at a preset flow rate, so that the foaming liquid is sucked into the first liquid inlet channel b through the second liquid inlet channel c and then diluted and mixed with water. In this way, when the foaming device 100 of the present application is applied to the foam shield system, the mixing water tank structure can be omitted, so that the overall structure of the foam shield system is more compact to meet the needs of miniaturized design.
[0031] See also Figure 3 and Figure 4 In some embodiments, the second liquid inlet channel c includes a first main flow channel c1 and a first throat channel c2, one end of the first throat channel c2 is connected to one side of the first liquid inlet channel b, the other end of the first throat channel c2 is connected to one end of the first main flow channel c1, the other end of the first main flow channel c1 is used to connect to a water supply source, the cross-sectional area of the first main flow channel c1 is greater than the cross-sectional area of the first throat channel c2, wherein the cross-sectional area of the first main flow channel c1 is a cross-sectional area perpendicular to the extension direction of the first main flow channel c1, and the cross-sectional area of the first throat channel c2 is a cross-sectional area perpendicular to the extension direction of the first throat channel c2. For example, as Figure 4 As shown in, in some embodiments, the first main channel c1 and the first throat c2 are both axisymmetric structures, the extension direction of the first main channel c1 is parallel to the central axis of the first main channel c1, and the cross-section of the first main channel c1 is the cross-section perpendicular to the central axis z1 of the first main channel c1, the extension direction of the first throat c2 is parallel to the central axis z2 of the first throat c2, and the cross-section of the first throat c2 is the cross-section perpendicular to the central axis z2 of the first throat c2.
[0032] Since the cross-sectional area of the first throat c2 is smaller than that of the first main channel c1, the flow rate of the bubbling liquid increases when it enters the first throat c2, and the pressure in the first throat c2 decreases, forming a low-pressure area in the first throat c2, which is conducive to sucking the bubbling liquid from the first main channel c1 into the first liquid inlet channel b.
[0033] In some embodiments, the second liquid inlet channel c further includes a contraction section c3, the first main channel c1 is connected to the first throat c2 through the contraction section c3, one end of the first main channel c1 is connected to the contraction section c3, and the other end of the contraction section c3 is connected to one end of the first throat c2. The cross-sectional area of the contraction section c3 is greater than the cross-sectional area of the first throat c2, and the cross-sectional area of the contraction section c3 gradually decreases along the direction from the first main channel c1 to the first throat c2, wherein the cross-sectional area of the contraction section c3 is a cross-sectional area perpendicular to the extension direction of the contraction section c3. For example, Figure 4 As shown, in some embodiments, the contraction section c3 has an axisymmetric structure, the extension direction of the contraction section c3 is parallel to the central axis z3 of the contraction section c3, and the cross section of the contraction section c3 is a cross section perpendicular to the central axis z3 of the contraction section c3.

[0043] In some embodiments, the central axis z1 of the first main flow channel c1, the central axis z3 of the contraction section c3, and the central axis z2 of the first throat channel c2 are all perpendicular to the central axis z4 of the first liquid inlet channel b.
[0044] In some embodiments, a liquid inlet connector 121 is formed on one side of the housing 12 , and the second liquid inlet channel c passes through the liquid inlet connector 121 .
