DETAILED DESCRIPTION
[0032] In order to make the technical problems, technical solutions and beneficial effects of the utility model clearer and more understandable, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.
[0033] Please refer to Figures 1 to 6 A foaming pump comprises a foaming main body 1 and a pump body 2, wherein,
[0034] The foaming main body 1 is provided with a first mixing cavity 111 and a second mixing cavity 112. Specifically, the first mixing cavity 111 is provided with an air inlet 121 and a liquid inlet 122. The first mixing cavity 111 and the second mixing cavity 112 are provided with a first communication port 113. The second mixing cavity 112 is further provided with a liquid outlet 123. The air inlet 121 is provided with a first one-way valve 3. The first one-way valve 3 is opened in the air inlet 121 air inlet state, which can avoid the air inlet 121 reverse water or air outlet. The first communication port 113 is provided with a second one-way valve 4. The second one-way valve 4 is opened in the liquid in the first mixing cavity 111 to the second mixing cavity 112 conveying state, which can avoid the water in the second mixing cavity 112 flowing into the first mixing cavity 111. The second mixing cavity 112 and the liquid outlet 123 are provided with a third one-way valve 5. The third one-way valve 5 is opened in the liquid outlet 123 external output liquid state, which can avoid the external water or gas entering the second mixing cavity 112 through the liquid outlet 123.
[0035] The pump body 2 is installed on the foaming main body 1, and the pumping working parts of the pump body 2 extend into the second mixing cavity 112.
[0036] In an embodiment, the pump body 2 is a diaphragm pump, and the working part of the pump body 2 is a diaphragm 21. In addition, the second one-way valve 4 and the third one-way valve 5 are opposite to the diaphragm 21, which can reduce the problem of single-sided sealing instability of the one-way valve.
[0037] Based on the above embodiments, to reduce molding difficulty, in one embodiment, the foaming body 1 is divided into multiple components, including a base 11 and an end cap 12. The diaphragm pump forms a mounting base 22 around the diaphragm sheet 21. The base 11 is mounted on the mounting base 22 of the diaphragm pump, and the end cap 12 is mounted on the side of the base 11 facing away from the mounting base 22. Preferably, the base 11 and the end cap 12 are mounted on the mounting base 22 using the same set of screws, resulting in strong integration and secure installation.
[0038] Regarding the internal structure, the first mixing chamber 111 is disposed between the base 11 and the end cap 12, and the second mixing chamber 112 is disposed between the base 11 and the mounting base 22. The liquid inlet 122 and the liquid outlet 123 are arranged in parallel and spaced apart, and liquid inlet connectors and liquid outlet connectors are respectively formed on the periphery of the end cap 12, which can avoid the messy arrangement of external pipes. In addition, the air inlet 121 is located on the top of the end cap 12. When the one-way valve fails, gas is discharged first from the air inlet 121, which can avoid or reduce the discharge of water from the air inlet 121.
[0039] During operation, the working component first creates a negative pressure in the second mixing chamber 112. At this time, the second mixing chamber 112 creates a suction effect on the first mixing chamber 111. The second one-way valve 4 and the first one-way valve 3 open in sequence. The liquid inlet 122 and the air inlet 121 respectively input cleaning liquid and air into the first mixing chamber 111. After the cleaning liquid and air are initially mixed in the first mixing chamber 111, they enter the second mixing chamber 112 through the first connecting port 113 and are mixed again. Finally, when the pump body 2 pressurizes the second mixing chamber 112, the mixed liquid is discharged from the liquid outlet 123.
[0040] In another embodiment, to further improve the mixing effect, a liquid outlet chamber 114 is also provided between the second mixing chamber 112 and the liquid outlet 123, and a second connecting port 115 is provided between the liquid outlet chamber 114 and the second mixing chamber 112, thereby further extending the mixing channel. Optionally, the liquid outlet chamber 114 is located close to the first mixing chamber 111 and is located between the seat 11 and the end cap 12, while the third one-way valve 5 is located at the second connecting port 115.
[0041] The foaming pump provided by this utility model has at least two mixing processes between the cleaning liquid and air during operation. The mixing path is long, the mixing is more uniform, and the subsequent foaming effect is better. In addition, the air inlet 121 and the second mixing chamber 112 are equivalent to having two layers of one-way valves, which can greatly reduce the impact of the pump body 2 on the air inlet 121 when it is pressurized, and avoid the problem of water leakage from the air inlet 121.
