The embodiments described below by reference to the drawings are exemplary and are for the purpose of explaining the present application only, and should not be understood as limiting the present application.

In the description of the utility model, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0034] In the description of the utility model, it should be pointed out that, unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0035] In the related art, when the gas, the washing medium and the water flow are mixed with each other, the formation of a large number of bubbles is effectively promoted by means of the shearing force and the turbulent effect of the fluid, so that the rich foaming effect is generated, and the washing quality and the user experience are improved. However, when the washing device inhales the gas to introduce the gas, there is obvious noise, which affects the user experience.

[0036] Reference will be made below Figures 1-6 The flow channel assembly according to the utility model embodiment is described.

[0037] As Figures 1-3 shown, the flow channel assembly 1 according to the utility model comprises a mixing flow channel 11, the mixing flow channel 11 is used for water flow to flow, and provides a space for the mixing of the gas, the washing medium and the water flow. The gas, the washing medium and the water flow are mixed in the mixing flow channel 11 to generate a foaming effect. The mixing flow channel 11 is formed with a liquid inlet and a liquid outlet, the liquid inlet is used to introduce the water flow, and the liquid outlet is used to discharge the mixed fluid.

[0038] The flow channel assembly 1 further comprises a gas suction flow channel 12, the gas suction flow channel 12 is used to provide the required gas for the mixing flow channel 11. The gas suction flow channel 12 communicates with the mixing flow channel 11, so that the gas can enter the mixing flow channel 11 through the gas suction flow channel 12 and be mixed with the washing medium and the water flow.

[0039] The flow channel assembly 1 further comprises a sound-damping member 13 arranged at the inlet of the air suction flow channel 12 and at least partially opposite to the inlet of the air suction flow channel 12, so that at least part of the sound-damping member 13 can directly face and affect the airflow flowing into the inlet of the air suction flow channel 12. Therefore, the gas will encounter the sound-damping member 13 before entering the air suction flow channel 12 through the inlet of the air suction flow channel 12. The sound-damping member 13 is formed with a plurality of sound-damping holes 131, so that the gas is forced to disperse and pass through the sound-damping holes 131 when flowing through the sound-damping member 13, thereby slowing down the flow speed of the gas. By dispersing the airflow and reducing the flow speed, the noise generated when the gas flows through the air suction flow channel 12 is reduced.

[0040] Therefore, according to the flow channel assembly 1 of the present application, by arranging the sound-damping member 13, the gas flow speed is effectively slowed down and the airflow is dispersed, thereby reducing the noise generated when the gas flows through the air suction flow channel 12.

[0041] According to some embodiments of the present application, as shown in Figures 1-6 The flow channel assembly 1 further comprises a housing 14 for accommodating and protecting the internal structure of the flow channel assembly 1. The mixing flow channel 11 and the air suction flow channel 12 are formed in the housing 14, and the mixing flow channel 11 and the air suction flow channel 12 are in communication inside the housing 14, so that the gas in the air suction flow channel 12 can be fully mixed with the scrubbing medium and the water flow in the mixing flow channel 11 to produce abundant foaming effect.

[0042] The air suction flow channel 12 extends to the surface of the housing 14 to form the inlet of the air suction flow channel 12 on the surface of the housing 14, so that the air suction flow channel 12 is not completely enclosed inside the housing 14, but extends from the inside of the housing 14 to the surface of the housing 14, thereby forming the inlet of the air suction flow channel 12 on the surface of the housing 14. The inlet allows external gas to be sucked into the air suction flow channel 12.

[0043] The sound-damping member 13 is connected to the surface of the housing 14, so that the sound-damping member 13 at least partially covers the inlet of the air suction flow channel 12, thereby playing a noise reduction role. Through the stable connection of the sound-damping member 13 and the housing 14, the relative position of the sound-damping member 13 and the inlet of the air suction flow channel 12 can be kept stable, thereby stably and continuously playing the noise reduction role.

[0044] According to some embodiments of the present application, as shown in Figure 2 and Figure 3 The sound-damping member 13 comprises a surrounding baffle 132, one end of the surrounding baffle 132 being connected to the surface of the housing 14, so that the sound-damping member 13 is fixed to the surface of the housing 14. The surrounding baffle 132 surrounds at least part of the outer periphery of the inlet of the air suction flow channel 12, thereby effectively guiding and controlling the airflow before it enters the air suction flow channel 12, reducing unnecessary airflow convection, and thereby further reducing the generation of noise.

[0045] The sound attenuation member 13 further comprises a shunt plate 133 which cooperates with the baffle plate 132 to achieve the noise reduction effect. The shunt plate 133 is connected to the other end of the baffle plate 132 to be spaced apart from the surface of the housing 14, so that the shunt plate 133 and the baffle plate 132 can guide and control the airflow as a whole (the sound attenuation member 13), and also allow the shunt plate 133 to maintain proper spacing with the surface of the housing 14 under the support of the baffle plate 132 without hindering the flow of gas at the inlet of the air inlet channel 12.

[0046] The shunt plate 133 is arranged opposite to the air inlet, so that the shunt plate 133 can directly face and affect the airflow flowing into the inlet of the air inlet channel 12. The shunt plate 133 is formed with a plurality of sound attenuation holes 131, so that the shunt plate 133 can disperse the airflow through the plurality of sound attenuation holes 131 to reduce noise.

[0047] According to some embodiments of the present application, as shown in Figures 1-5 The baffle plate 132 surrounds the inlet of the air inlet channel 12 at an angle a satisfying 270°≤a≤360°. The angle of the baffle plate 132 surrounding the inlet of the air inlet channel 12 represents the space included angle formed by the baffle plate 132 when surrounding the inlet of the air inlet channel 12.

[0048] When the baffle plate 132 completely surrounds the inlet of the air inlet channel 12, the angle a is 360°, which can effectively guide and control the airflow while minimizing the convection of the airflow to reduce noise.

[0049] When the baffle plate 132 partially surrounds the inlet of the air inlet channel 12, the angle a is between 270° and 360°. Although the baffle plate 132 does not completely surround the inlet of the air inlet channel 12, it can still effectively reduce the convection of the airflow to provide airflow guiding and noise reduction effect.

[0050] According to some embodiments of the present application, the sound attenuation holes 131 are configured as circular holes, square holes, long strip-shaped holes or irregularly shaped holes. The sound attenuation holes 131 can have different shapes. Specifically, the circular hole has a curved side without straight sides or corners; the square hole is a hole with four equal sides perpendicular to each other; the long strip-shaped hole is a hole with a length much greater than the width; and the irregularly shaped hole is a hole with irregular shape. The circular hole, the square hole and the long strip-shaped hole have simple geometric shapes, which are easy to manufacture and process. The irregularly shaped hole has a more complex geometric shape to optimize airflow control and noise reduction effect.

[0051] According to some embodiments of the present application, as shown in Figure 2 and Figure 3As shown, the mixing flow channel 11 includes a throat 111 which is in communication with the air intake flow channel 12. The throat 111 is the portion of the mixing flow channel 11 with the smallest cross section. When the water flow in the mixing flow channel 11 flows through the throat 111 with a sudden decrease in cross section, the flow rate increases while the pressure decreases, forming a low pressure zone which facilitates the intake of gas into the mixing flow channel 11 through the air intake flow channel 12.

[0052] The mixing flow channel 11 further includes a converging section 112 which is in communication with the throat 111 and is disposed upstream of the throat 111. The converging section 112 has a cross section which gradually decreases from upstream to the throat 111, gradually accelerating the water flow so that the water flow reaches a high flow rate when it reaches the throat 111.

[0053] The mixing flow channel 11 further includes a diverging section 113 which is in communication with the throat 111 and is disposed downstream of the throat 111. The diverging section 113 has a cross section which gradually increases from the throat 111 to downstream, gradually decelerating the fluid after it leaves the throat 111 while gradually increasing the pressure, facilitating the stable flow of the fluid in the mixing flow channel 11 and promoting the mixing between the gas and the liquid, producing a foaming effect.

[0054] After the water flow enters the mixing flow channel 11 from the liquid inlet, it first passes through the converging section 112. The converging section 112 has a cross section which gradually decreases, forcing the water flow to gradually accelerate so that the water flow reaches a high flow rate when it reaches the throat 111. The throat 111 is the portion of the mixing flow channel 11 with the smallest cross section. When the water flow flows through the throat 111, the flow rate reaches a maximum while the pressure significantly decreases, so the throat 111 has a strong suction effect, facilitating the intake of gas into the mixing flow channel 11 through the air intake flow channel 12. After the water flow and the gas mix in the throat 111, they enter the diverging section 113 together. The diverging section 113 has a cross section which gradually increases from the throat 111 to downstream, providing space for the fluid to gradually decelerate. In the process of deceleration of the fluid, the pressure of the fluid gradually increases, facilitating the stable flow of the fluid in the mixing flow channel 11 and optimizing the interaction between the gas and the water flow, producing a good foaming effect.

[0055] According to some embodiments of the present application, as shown in Figs. Figure 2 and Figure 3 As shown, a receiving cavity 15 adapted to contain a washing medium is formed in the housing 14, and the receiving cavity 15 is in communication with the throat 111, so that the washing medium can flow out of the receiving cavity 15 under the low pressure of the throat 111 and enter the mixing flow channel 11 through the throat 111. The gas, the washing medium and the water flow mix in the mixing flow channel 11 to produce a foaming effect.

[0056] According to some embodiments of the present application, the shell 14 is provided with a first matching part, and the first matching part is used to provide a connecting point for the sound attenuation piece 13, so as to cooperate with a second matching part on the sound attenuation piece 13. The sound attenuation piece 13 is provided with the second matching part, and the second matching part is matched with the first matching part, so as to ensure that the second matching part and the first matching part can be tightly and stably connected together. The second matching part and the first matching part are detachably connected, so that the second matching part and the first matching part can be easily separated or reconnected, so that the user can easily replace or maintain the sound attenuation piece 13 when needed, which not only improves the flexibility of the flow channel assembly 1, but also reduces the maintenance cost.
