[0029] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where 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 by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0030] The present utility model relates to a microbubble water outlet device, which includes a water inlet assembly 100, a filtration assembly 200, a water control assembly 300, and a microbubble generation assembly 400.

[0031] As Figure 1 and Figure 2 shown, the water inlet assembly 100 is provided with a first water inlet 101 and a first water outlet 102. The shape of the water inlet assembly 100 is not limited and can be cylindrical, tubular, box-shaped, etc. The inside of the water inlet assembly 100 is hollow, and the filtration assembly 200 is installed in the water inlet assembly 100. A first channel 103 is defined between the filtration assembly 200 and the water inlet assembly 100. The first channel 103 communicates with the first water inlet 101 and the first water outlet 102. The filtration assembly 200 is installed in the water inlet assembly 100. The filtration assembly 200 includes a filter body 210, and the filter body 210 can be a filter screen, PP cotton, filter membrane, etc., which are components that can allow water to pass through and filter out fixed impurities in the water. There is a certain interval between the outer side of the filter body 210 and the water inlet assembly 100, and the interval is the first channel 103. The first channel 103 communicates with both the first water inlet 101 and the first water outlet 102. A second channel 220 is provided inside the filter body 210, and the second channel 220 has a second water inlet 221 and a second water outlet 222. The first water inlet 101 and the second water inlet 221 can be communicated. The water filtration function is realized between the first channel 103 and the second channel 220 through the filter body 210. The water control assembly 300 is used to control the opening and closing of the first water outlet 102, the second water inlet 221, and the second water outlet 222. The microbubble generation assembly 400 can be installed on the water control assembly 300. The microbubble generation assembly 400 is arranged on the downstream side of the second water outlet 222, and the water inlet end 411 of the microbubble generation assembly 400 is communicated with the second water outlet 222.

[0032] During actual use, the first water inlet 101 can be connected to an external water supply system through a water pipe, and the water supply system can be a tap water pipe, a water heater, etc. According to the opening and closing conditions of the first water outlet 102, the second water inlet 221, and the second water outlet 222 set by the water control assembly 300, the microbubble water outlet device has at least two working modes, namely the microbubble water outlet mode and the cleaning mode, specifically as follows:

[0033] As Figure 2 and Figure 4As shown in the figure, the microbubble water outlet mode: the water control component 300 controls the first water outlet 102 and the second water inlet 221 to be blocked and closed, and the second water outlet 222 is opened. Water enters from the first water inlet 101. Since the second water inlet 221 is closed, the water entering from the first water inlet 101 can only flow into the first channel 103. The water flow in the first flow channel passes through the filter body 210 for water filtration and then flows into the second channel 220. The filtered water in the second channel 220 flows from the second water outlet 222 to the microbubble generation component 400, and the water flow forms microbubble water through the microbubble generation component 400 and is output for users to use.

[0034] After using the microbubble water outlet mode for a long time, impurities in the water will accumulate and adhere to the outer side of the filter body 210 or in the first flow channel, affecting the water filtration effect of the filter body 210. At this time, the water control component 300 is switched to the cleaning mode.

[0035] As Figure 3 and Figure 5 As shown in the figure, the cleaning mode is: the water control component 300 controls the second water outlet 222 to be blocked and closed, and the first water outlet 102 and the second water inlet 221 are opened. Water enters from the first water inlet 101. A part of the water is diverted into the first flow channel, and the other part of the water enters the second flow channel from the second water inlet 221. The water entering the first flow channel flushes the outer surface of the filter body 210 and the inner wall of the first flow channel; the water entering the second flow channel from the second water inlet 221 will flow from the inner side to the outer side of the filter body 210 due to the closure of the second water outlet 222, so as to perform backwashing on the outer side of the filter body 210, thereby fully flushing the solid impurities accumulated and adhered on the outer surface of the filter body 210 and in the first flow channel. Finally, the fixed impurities will be discharged from the first water outlet 102 to the outside of the water inlet component 100 along with the water, thus realizing the self-cleaning function. By combining the direct flushing and backwashing methods, the filter body 210 can be fully rinsed, the sewage discharge is more thorough, and the service life of the microbubble generation component 400 can be effectively extended.

[0036] Among them, the water control component 300 can independently control the opening and closing of the first water outlet 102, the second water inlet 221, and the second water outlet 222 by a plurality of valve parts. In this embodiment, the water control component 300 is installed on the water inlet component 100 as an integral assembly member, and the water control component 300 and the water inlet component 100 can move relative to each other. The water control component 300 has a first position and a second position when moving relative to the water inlet component 100. In the illustrated direction, the water control component 300 moves up and down relative to the water inlet component 100. When the water control component 300 moves upward to the first position, the second water outlet 222 is opened, and the second water inlet 221 and the first water outlet 102 are blocked. At this time, the microbubble water outlet device enters the microbubble water outlet mode. When the water control component 300 moves downward to the second position, the second water outlet 222 is blocked, and the second water inlet 221 and the first water outlet 102 are opened. At this time, the microbubble water outlet device enters the cleaning mode.

[0037] In some specific embodiments of the present utility model, such as Figure 1 and Figure 2 shown, the water inlet component 100 includes a housing 110 and an upper end cover 120.
