Detailed Implementation

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] This utility model relates to a foaming device, including a water inlet channel 110, a first flow channel 120, a second flow channel 130, a third flow channel 140, a liquid inlet channel 150, a first mixing chamber 160, a first air inlet channel 170, and a second air inlet channel 180.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the water inlet channel 110, the first flow channel 120, the second flow channel 130, and the third flow channel 140 are connected in sequence. The water inlet channel 110 can be configured as a channel structure with equal inner diameters throughout, or it can be configured as a cone or other shape with unequal inner diameters throughout. Similarly, the first flow channel 120 can be configured as a channel structure with equal inner diameters throughout, or it can be configured as a cone or other shape with unequal inner diameters throughout, with the minimum inner diameter of the water inlet channel 110 being greater than the maximum inner diameter of the first flow channel 120. The liquid inlet channel 150 and the first air inlet channel 170 are both connected to the first mixing chamber 160. The water inlet channel 110 is used to connect to an external water supply system, such as a tap water pipe or a water heater. The first mixing chamber 160 is connected to the junction of the first flow channel 120 and the second flow channel 130. The second air inlet channel 180 is connected to the junction of the second flow channel 130 and the third flow channel 140. The first air inlet channel 170 and the second air inlet channel 180 are respectively connected to the external environment of the foaming device. Foaming agents such as hand sanitizer, shower gel, and shampoo are supplied through the liquid inlet channel 150. During use, if... Figure 5As shown, water flows sequentially along the inlet channel 110, the first flow channel 120, the second flow channel 130, and the third flow channel 140. When the water flows through the inlet channel 110, the first flow channel 120, and the second flow channel 130, a Venturi effect is generated, thereby creating a negative pressure at the connection between the first flow channel 120 and the second flow channel 130. Under the action of negative pressure, the foaming liquid in the liquid inlet channel 150 and the air in the external environment can be drawn into the first mixing chamber 160 through the first air inlet channel 170. The water in the first flow channel 120 will flow into the first mixing chamber 160. The water, foaming liquid, and air are mixed and foamed once in the first mixing chamber 160 to form foam liquid, which flows into the second flow channel 130. As the foaming liquid flows through the second flow channel 130 and the third flow channel 140, the Venturi effect is generated again, creating a negative pressure at the junction of the second and third flow channels 140. Under this negative pressure, air from the external environment is drawn into the junction of the second and third flow channels 140 through the second air intake channel 180, where it mixes with the foaming liquid for secondary foaming. The foaming liquid is then discharged from the third flow channel 140 for user use. Through this two-stage mixing process, the foaming liquid is fully foamed to form a large number of bubbles, resulting in a high foaming rate and ease of use for users.

[0029] In one embodiment, such as Figure 1 and Figure 5As shown, the second flow channel 130 can be configured as a channel structure with equal inner diameters throughout, or as a cone or other shape with unequal inner diameters throughout; the third flow channel 140 can be configured as a channel structure with equal inner diameters throughout, or as a cone or other shape with unequal inner diameters throughout. In this embodiment, a conical constriction 122 is provided at the connection between the water inlet channel 110 and the first flow channel 120, and the first flow channel 120 is configured as a column with equal diameters throughout. The constriction 122 gradually narrows towards the first flow channel 120. The minimum inner diameter of the constriction 122 is equal to the inner diameter of the first flow channel 120. The maximum inner diameter of the first flow channel 120 is smaller than the minimum inner diameter of the second flow channel 130. In this embodiment, the first flow channel 120 is configured as a column with equal diameters throughout, and the second flow channel 130 is configured as a column with equal diameters throughout. Along the water flow direction, the downstream end of the first flow channel 120 is defined as the first end 121, and the upstream end of the second flow channel 130 is defined as the second end 131. The first end 121 and the second end 131 are coaxially positioned and opposite to each other, with a first gap 201 between them. The first gap 201 is located in the first mixing chamber 160, that is, the first gap 201 serves as the connection point between the first flow channel 120 and the second flow channel 130, and the first gap 201 is part of the first mixing chamber 160. When water flows into the first flow channel 120 through the water inlet channel 110, the flow velocity increases, and a negative pressure is generated when the water flows through the first gap 201, drawing the foaming liquid in the liquid inlet channel 150 and the gas in the first air inlet channel 170 into the first mixing chamber 160 for mixing. The water in the first flow channel 120 is ejected from the first end 121 and impacts the second end 131 of the second flow channel 130, causing the foam liquid in the first mixing chamber 160 to flow into the second flow channel 130.

[0030] Furthermore, the maximum inner diameter of the second flow channel 130 is smaller than the minimum inner diameter of the third flow channel 140. In this embodiment, as... Figure 2 and Figure 5 As shown, the second flow channel 130 is configured as a column with uniform diameter at all points, and the third flow channel 140 is configured as a column with uniform diameter at all points. Along the water flow direction, the downstream end of the second flow channel 130 is defined as the third end 132, and the upstream end of the third flow channel 140 is defined as the fourth end 141. The third end 132 and the fourth end 141 are coaxial and positioned opposite each other, with a second gap 202 between them. The second air inlet channel 180 communicates with the second gap 202. After the foam liquid flows from the first mixing chamber 160 to the second flow channel 130, the flow velocity increases. When the foam liquid flows through the second gap 202, a negative pressure is formed, and gas from the external environment is drawn into the second gap 202 through the second air inlet channel 180, where the air mixes with the foam liquid for secondary foaming. A first one-way valve 301 is installed in the second air inlet channel 180. The first one-way valve 301 controls the external airflow to be drawn into the interior of the second air intake channel 180 in one direction, preventing liquid from being sprayed out of the second air intake channel 180.

[0031] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the foaming device also includes a first housing 400 and a first air pipe 500. The interior of the first housing 400 is hollow, forming a liquid storage chamber 410. The liquid storage chamber 410 is used to store foaming liquid. The first housing 400 is provided with a first connecting pipe 420 and a second connecting pipe 430. The first connecting pipe 420 and the second connecting pipe 430 can be integrally formed on the first housing 400, or they can be installed on the first housing 400 as independent components. The first connecting pipe 420 communicates with the liquid storage chamber 410. A first air inlet channel 170 is formed inside the first air pipe 500. The first air pipe 500 passes through the first connecting pipe 420, and a liquid inlet channel 150 is defined between the outer wall of the first air pipe 500 and the inner wall of the first connecting pipe 420. A first mixing chamber 160 creates a negative pressure on the first connecting pipe 420. The first connecting pipe 420 is communicated with the first mixing chamber 160. Air is delivered to the first connecting pipe 420 through the first air pipe 500, and foaming liquid flows into the first connecting pipe 420 through the liquid inlet channel 150. Air and foaming liquid mix in the first connector 420 and flow into the first mixing chamber 160. The interior of the second connector 430 forms part of the water inlet channel 110. The second connector 430 is used to connect to an external water supply system.

[0032] Based on the above embodiments, such as Figure 1 and Figure 2 As shown, a second check valve 302 is installed in the first connecting pipe 420. The second check valve 302 is located downstream of the liquid inlet channel 150 and the first air inlet channel 170. The foaming liquid and air flow into the first mixing chamber 160 after passing through the second check valve 302. The second check valve 302 controls the unidirectional flow of the fluids flowing through it towards the first mixing chamber 160, preventing the fluids in the first mixing chamber 160 from flowing back into the liquid inlet channel 150 and the first air inlet channel 170.

[0033] Furthermore, the foaming device also includes a cover 600. The upper part of the liquid storage chamber 410 is configured as an opening, and the cover 600 covers the upper part of the liquid storage chamber 410. The cover 600 is provided with a first interface 610, a second interface 620, and a liquid filling port 630. One end of the second connecting pipe 430 is connected to the first interface 610, and an external water supply pipe is connected to the first interface 610. One end of the first air pipe 500 is connected to the second interface 620, and the first air pipe 500 passes through the liquid storage chamber 410. The second interface 620 positions one end of the first air pipe 500. The liquid filling port 630 communicates with the liquid storage chamber 410. The user can add foaming liquid to the liquid storage chamber 410 through the liquid filling port 630.

[0034] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the foaming device also includes a second housing 700, a first connector 810, and a second connector 820. The first housing 700 and the second housing 700 can be fixed to each other by means of screws, snap-fit, or other methods. The second housing 700 has an internal mounting cavity 710. The first connector 810 and the second connector 820 are installed in the mounting cavity 710. The mounting cavity 710 is separated by the first connector 810 and the second connector 820. A sealing ring can be provided between the first connector 810 and the mounting cavity 710 to improve the sealing at the connection. A sealing ring can also be provided between the second connector 820 and the mounting cavity 710 to improve the sealing at the connection. Along the water flow direction, the first connector 810 is located upstream of the second connector 820. The upstream side of the first connector 810 and the mounting cavity 710 form part of a water inlet channel 110, which together with the aforementioned second connector 430 forms the water inlet channel 110. A first mixing chamber 160 is formed between the downstream side of the first connector 810, the mounting cavity 710, and the upstream side of the second connector 820. The first connector 810 has a fourth flow channel 811 and a first flow channel 120. The fourth flow channel 811 connects the liquid inlet channel 150 and the first air inlet channel 170 to the first mixing chamber 160; alternatively, the fourth flow channel 811 can connect the downstream end of the first connector 420 to the first mixing chamber 160. A second flow channel 130 is disposed on the second connector 820. Furthermore, the foaming device also includes a third housing 900. The second housing 700 and the third housing 900 can be fixed to each other by screws, snap-fitting, or other means. The third housing 900 has a second air inlet channel 180 and a third flow channel 140. A second mixing chamber 901 is defined between the second connector 820 and the third housing 900, and the second air inlet channel 180 communicates with the second mixing chamber 901. The second interval 202 is located in the second mixing chamber 901, that is, the second interval 202 is part of the second mixing chamber 901. External air is drawn into the second mixing chamber 901 through the second air intake channel 180, and the foam liquid is mixed and foamed with the gas in the second mixing chamber 901.
