[0012] Furthermore, the foaming body includes an injection head, a first pipe and a second pipe connected in sequence along the foaming direction, the water flow cross-sectional area of ​​the water outlet end of the injection head is smaller than the water flow cross-sectional area of ​​the water inlet end of the first pipe, and the water flow cross-sectional area of ​​the water outlet end of the first pipe is smaller than the water flow cross-sectional area of ​​the water inlet end of the second pipe.

Therefore, negative pressure is generated between the spray head and the first pipe and between the first pipe and the second pipe, and then the foaming liquid and air are sucked into the water flow to form foam liquid, thereby achieving the foaming effect under the non-electric configuration.

[0025] 3. In a foaming device proposed by the present invention, during the foaming process, the negative pressure area is mainly concentrated on the water outlet end face of the injection head and the rear end of the water outlet end face of the first pipe.

[0027] 5. In a foaming device proposed by the present invention, the water inlet end of the first pipe is provided with a contraction section whose cross-sectional area gradually decreases along the foaming direction, and the liquid inlet is arranged in the contraction section to enhance the negative pressure effect generated by the liquid inlet.

[0028] 6. In a foaming device proposed by the present invention, a pressure-stabilizing valve is provided between the water inlet and the water supply source to stabilize the water flow pressure and eliminate the influence of pipeline water pressure fluctuation on the foaming effect.

[0029] 7. In a foaming device proposed by the present invention, part of the position of the liquid pipette is higher than the liquid level of the foaming liquid in the liquid storage box, so as to prevent the foaming liquid from being squeezed into the liquid inlet under the action of its own gravity when no foaming occurs, thereby causing waste of the foaming liquid.

[0042] Embodiment 1

[0043] Combine the following Figure 1-7 The present invention is described in detail.

[0044] This embodiment provides a foaming device 10, comprising:

[0045] The water storage box 20 is provided with a drain outlet 201;

[0046] The liquid storage box 301 is used to store the foaming liquid; the opening of the liquid storage box 301 is sealed with a box cover 302, the box cover 302 is provided with a liquid filling port 303, and the liquid filling port 303 is provided with a detachable plug 304;

[0047] The foaming body 50 is provided with a liquid inlet 5022 connected to the liquid storage box 301 and an air inlet 5031 connected to the atmosphere in sequence along the foaming direction;

[0048] The drainage device is arranged in the water storage box 20, including a blocking member 701 sealed in the drainage port 201 and a driving member 702 for driving the blocking member 701 to open the drainage port 201, and after the blocking member 701 opens the drainage port 201, the drainage port 201 is closed as the liquid level in the water storage box 20 decreases; the blocking member 701 adopts a drainage buoy, and in other embodiments, it can also be a flap valve; and

[0049] The foaming water inlet valve 40 is provided with a water inlet 402, a first water outlet 403, a second water outlet 404 and a water inlet float 401, wherein the first water outlet 403 is connected to the water storage box 20, and the second water outlet 404 is connected to the water inlet end of the foaming body 50;

[0050] When in use, the user drives the blocking member 701 through the driving member 702 to open the drain port 201, and the water inlet float 401 drops to the first preset height with the liquid level, thereby opening the foaming water inlet valve 40, so that the water inlet 402 is connected to the first water outlet 403 and the second water outlet 404, and the water from the second water outlet 404 flows through the foaming channel, thereby sucking the foaming liquid and air into the water flow in turn to form foam, and at the same time, the blocking member 701 closes the drain port 201 as the liquid level drops, and the first water outlet 403 replenishes the water in the water storage box 20, until the water inlet float 401 rises to the second preset height with the liquid level, thereby closing the foaming water inlet valve 40, and the first water outlet 403 and the second water outlet 404 stop discharging water and foaming. Therefore, the device adopts a purely mechanically controlled foaming mode, avoids the use of a peristaltic pump and its power module, reduces production costs and usage noise, and improves user experience.

[0051] In this embodiment, the foaming water inlet valve 40 can adopt a common water inlet valve 160, the water outlet is connected to the water inlet end of the foaming body 50, and the water replenishment port is connected to the water outlet box, so the water outlet constitutes the second water outlet 404, and the water replenishment port constitutes the first water outlet 403. The length of the foaming time depends on the time from opening to closing of the foaming water inlet valve 40, which is related to the water outlet flow rate of the water replenishment port, the drainage flow rate of the drain port 201, and the capacity of the water storage box 20. Therefore, the foaming time can be changed by adjusting one or more of the water outlet flow rate of the water replenishment port, the drainage flow rate of the drain port 201, and the capacity of the water storage box 20. The opening and closing of the foaming water inlet valve 40 can also be controlled by changing the first preset height and the second preset height to meet the diverse usage needs of users.

[0052] In this embodiment, Figure 7 As shown, the foaming body 50 includes a spray head 501, a first pipe 502, and a second pipe 503 connected in sequence along the foaming direction. The water flow cross-sectional area of ​​the water outlet end of the spray head 501 is smaller than the water flow cross-sectional area of ​​the water inlet end of the first pipe 502, and the water flow cross-sectional area of ​​the water outlet end of the first pipe 502 is smaller than the water flow cross-sectional area of ​​the water inlet end of the second pipe 503. When the water flows through the spray head 501, the first pipe 502, and the second pipe 503 in sequence, negative pressure will be generated between the spray head 501 and the first pipe 502, and between the first pipe 502 and the second pipe 503, thereby sucking the foaming liquid and air into the water flow to form a foam liquid, thereby achieving a foaming effect under a non-electric configuration.

[0053] In this embodiment, based on the Venturi principle, the water outlet end face of the spray head 501 and the back of the water outlet end face of the first pipe 502 respectively form a first negative pressure area 601 and a second negative pressure area 602. Therefore, the liquid inlet 5022 is provided in the first pipe 502, and the water outlet end face of the spray head 501 is located downstream of the liquid inlet 5022 along the bubbling direction, and the air inlet 5031 is provided in the second pipe 503, and the water outlet end face of the first pipe 502 is located downstream of the air inlet 5031 along the bubbling direction, so as to ensure the negative pressure suction effect.

[0054] In this embodiment, the water flow cross-sectional area of ​​the water outlet end of the spray head 501 is smaller than the water flow cross-sectional area of ​​the water inlet end thereof, thereby increasing the flow velocity of the water flow, thereby reducing the pressure on the surface of the fluid, optimizing the negative pressure effect, and ensuring the liquid inlet effect. The water inlet end of the first pipe 502 is provided with a contraction section 5021 whose cross-sectional area gradually decreases along the bubble outlet direction, and the liquid inlet 5022 is arranged at the contraction section 5021, so as to improve the negative pressure effect generated by the liquid inlet 5022.

[0055] In this embodiment, Figure 7 As shown, the water inlet end of the spray head 501 is connected to an adapter 80, and the adapter 80 is provided with a first reducing section 801 and a second reducing section 802 in sequence along the bubbling direction. The cross-sectional area of ​​the first reducing section 801 gradually decreases along the bubbling direction, and the cross-sectional area of ​​the second reducing section 802 gradually increases along the bubbling direction, so that the water flow is compressed and then released, thereby precipitating air in the water, increasing the air content in the water, and improving the foaming effect.

[0056] In this embodiment, the water inlet 402 is connected to the water supply source, and a pressure regulating valve 90 is provided between the water inlet 402 and the water supply source to stabilize the water flow pressure, eliminate the influence of pipeline water pressure fluctuation on the foaming effect, and ensure accurate suction of the foaming liquid. When the plugging member 701 adopts a drainage float, its cross-sectional area gradually increases in the direction away from the drain port 201, so as to facilitate closing the drain port 201 during the descent of the plugging member 701.

[0057] In the present embodiment, a pipette 100 is also included, one end of the pipette 100 is connected to the liquid inlet 5022, one end of the pipette 100 is connected to the liquid storage box 301, and part of the position of the pipette 100 is higher than the liquid level of the foaming liquid in the liquid storage box 301, so as to prevent the foaming liquid from being squeezed into the liquid inlet 5022 under its own gravity when not foaming, thereby causing waste of the foaming liquid. Further, the liquid storage box 301 is provided with an installation channel, and after the other end of the pipette 100 is inserted into the installation channel, the pipette 100 is bent so that its port is close to the bottom of the liquid storage box 301. The liquid level of the foaming liquid in the liquid storage box 301 is not higher than the installation channel, so as to ensure that the bent portion of the pipette 100 is higher than the liquid level of the foaming liquid.
