DETAILED DESCRIPTION

[0035] The utility model discloses a kind of foaming devices of cleaning device sectional view; Figures 1-8 The utility model discloses a kind of foaming devices of cleaning device sectional view;

[0036] Embodiment one

[0037] A kind of foam mixing mechanism, it is applied to cleaning device, at least liquid outlet end and cleaning device connection, including the water inlet channel 101, foaming channel 201 and water outlet channel 30 sequentially communicated along water outlet direction, water inlet channel 101 is equipped with water inlet A 1011;

[0038] Material cavity 60 is communicated in foaming channel 201;And,

[0039] Switch piece 70, switch piece 70 is used to open water flow, so that water flow is generated negative pressure when flowing through foaming channel 201 from water inlet channel 101, to clean liquid in material cavity 60 is absorbed to foaming channel 201 and water flow is mixed, and is flowed out by water outlet channel 30.

[0040] In use, the water inlet flow is opened by operating the switch 70, so that the water flow generates negative pressure when flowing through the foaming channel 201, thereby sucking the cleaning liquid stored in the material cavity 60 into the foaming channel 201 to mix with the water flow, the cleaning liquid is foamed in the foaming channel 201, and the foam flows out of the cleaning device. The cleaning medium in the form of foam is more likely to uniformly cover the dirt than the cleaning medium in the form of common liquid, thereby improving the cleaning effect, and only single-handed operation is required throughout, thereby improving the user operation experience.

[0041] In this embodiment, the foaming channel 201 includes a first variable-diameter section 2011 and a second variable-diameter section 2012 connected in sequence along the water outlet direction. The water passage cross-sectional area of the first variable-diameter section 2011 gradually decreases along the water outlet direction, the water passage cross-sectional area of the second variable-diameter section 2012 gradually increases along the water outlet direction, and the material cavity 60 is connected to one end of the second variable-diameter section 2012 close to the first variable-diameter section 2011. Specifically, when the water inlet flow flows through the first variable-diameter section 2011, the gradually decreasing water passage cross-sectional area accelerates the water inlet flow. When the accelerated water inlet flow enters the second variable-diameter section 2012, negative pressure is generated in the second variable-diameter section 2012, thereby sucking the cleaning liquid in the material cavity 60 out, achieving automatic liquid addition, and avoiding manual liquid addition by the user. Further, a constant-diameter section 2013 with a constant water passage cross-sectional area is connected between the first variable-diameter section 2011 and the second variable-diameter section 2012, so that the water inlet flow stabilizes before flowing into the second variable-diameter section 2012, thereby improving the negative pressure effect.

[0042] In this embodiment, the liquid outlet channel 80 is further included. One end of the liquid outlet channel 80 is connected to the liquid outlet of the material cavity 60, and the other end of the liquid outlet channel 80 is connected to one end of the second variable-diameter section 2012 close to the first variable-diameter section 2011. A one-way valve is arranged in the liquid outlet channel 80 and opens in the liquid outlet direction of the material cavity 60. The one-way valve prevents the cleaning liquid from leaking from the material cavity 60 when the water inlet flow is closed, thereby avoiding waste of the cleaning liquid.

[0043] In this embodiment, the one-way valve includes a blocking piece 801 that closes and opens the liquid outlet channel 80, and a restoring piece 802 that drives the blocking piece 801 to move in the reverse direction of the liquid outlet direction. When the water inlet flow flows through the second variable-diameter section 2012 to generate negative pressure, the negative pressure attracts the blocking piece 801 to move against the restoring force of the restoring piece 802, thereby opening the liquid outlet channel 80, and the cleaning liquid flows out of the material cavity 60. When there is no water flow flowing through the second variable-diameter section 2012, the blocking piece 801 closes the liquid outlet channel 80 under the restoring force of the restoring piece 802.

[0044] In this embodiment, if the user only needs clean water without cleaning liquid when using, clean water can be added in the material cavity 60 or the material cavity 60 is empty. At this time, the water flowing out of the water outlet channel 30 is clean water.

A locking cap 40 is also included, which has a through hole for the foaming component 20 to pass through and is adapted to one end of the body 10. Specifically, a limiting protrusion 202 is provided on the outer side of the foaming component 20. When the locking cap 40 is connected to one end of the body 10, the locking cap 40 abuts against the limiting protrusion 202, thereby fixing the foaming component 20 to the body 10.

The air inlet channel 1302 is located at one end of the material cavity 60, and the air inlet channel 1302 is provided with a silica gel one-way valve 1303 which is opened in one direction along the air inlet direction, so as to avoid the cleaning liquid in the material cavity 60 flowing out.
