As shown in fig. 1, 2 and 3, the case 100 is not limited in shape and may have a rectangular box shape with an open top. The inside of the box body 100 is a hollow water chamber 110, and a water inlet 120 is provided on the sidewall of the box body 100, and the water inlet 120 may be a hollow cylindrical structure extending outward from the sidewall of the box body 100. The water inlet 120 is communicated with the water chamber 110 for connecting a water pipe of the instant heating faucet. The bottom of the combination body is provided with a water outlet 130, the water outlet 130 is communicated with the water cavity 110, and the water outlet 130 may be a hollow cylindrical structure extending downwards from the bottom of the box body 100. As shown in fig. 1, 2 and 5, the ventilation cover 200 is installed at the bottom of the box body 100, an air chamber 210 is opened inside the ventilation cover 200, when the ventilation cover 200 is installed at the bottom of the box body 100, the air chamber 210 surrounds the water outlet 130, and an exhaust port 211 communicated with the outside is formed between the bottom of the air chamber 210 and the water outlet 130. An exhaust flow passage 140 is provided in the water chamber 110, and the exhaust flow passage 140 communicates the water chamber 110 with the exhaust chamber 210.

When the cover 300 is closed on the box 100, the baffle 310 extends into the water chamber 110, and the baffle 310 is located between the water inlet 120 and the steam exhaust channel 140. There is a certain distance between the baffle 310 and the water inlet 120, and the baffle 310 is spatially located on an axial extension line of the water inlet 120 toward the water chamber 110.

In use, the water pipe of the instant heating faucet is connected to the water inlet 120, and hot water in the water pipe is injected into the water cavity 110 through the water inlet 120. Under the action of water pressure, hot water is injected onto the baffle 310 and flows downwards along the baffle 310, and the baffle 310 can prevent the water flow from forming a rotational flow around the axial direction of the water outlet 130 in the water chamber 110. The steam generated in the hot water rises, the water level of the hot water in the water cavity 110 gradually rises, the air pressure in the water cavity 110 increases, the steam enters the steam discharging flow channel 140 to be discharged out of the water cavity 110 and enters the air cavity 210, and the steam which just enters the water cavity 110 needs to flow downwards to cross the bottom of the baffle plate 310 and then flows towards the steam discharging flow channel 140. The water in the water chamber 110 is discharged from the water outlet 130 for use by a user, and the steam is discharged to the external environment along the steam discharge flow passage 140, the air chamber 210, and the steam discharge port 211.

The upper and lower ends of the steam discharge flow path 140 are opened, the upper end thereof is communicated with the water chamber 110, and the lower end thereof is opened from the bottom of the box body 100 to be communicated with the air chamber 210. The upper end of the steam exhaust flow channel 140 is higher than the bottom of the baffle 310 extending into the water cavity 110 at the height position in the water cavity 110, so that the steam is ensured to enter the steam exhaust flow channel 140 after bypassing the baffle 310. Further, two steam discharge channels 140 are arranged in the water cavity 110, and the two steam discharge channels 140 can be respectively and symmetrically arranged on two side walls of the water cavity 110, so that steam can be discharged from the steam discharge ports 211 relatively uniformly after entering the air cavity 210 from the steam discharge channels 140.
