[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0026] See Figures 1-9 The water-blocking and venting structure of the cleaning device includes a cover 1 and a water-blocking and venting assembly 2 disposed on the top of the cover 1. The top of the cover 1 is provided with a first water-blocking rib 3. The water-blocking and venting assembly 2 is provided with a water-blocking plate 4, a second water-blocking rib 5 and a guide rib 6. An venting channel 7 is formed between the cover 1, the water-blocking plate 4 and the second water-blocking rib 5. An air outlet channel 8 is formed between the guide rib 6 and the cover 1, facing one side of the cover 1 and connected to the outside. The venting channel 7 is connected to the air outlet channel 8. The water-blocking plate 4 covers the bottom of the venting channel 7. The first water-blocking rib 3 is disposed on the top of the venting channel 7. The second water-blocking rib 5 spans across the venting channel 7. The first water-blocking rib 3 and the second water-blocking rib 5 are staggered vertically to block water from entering the venting channel 7.
[0027] The cleaning device is a baby bottle washing machine, which includes an inner container and a top cover a. The top cover a closes to the top of the inner container, which is used to hold baby bottles for cleaning and drying. Figure 1 As shown by the arrows (solid arrows indicate water flow, dashed arrows indicate steam flow), during bottle cleaning, water inside the inner liner sprays onto the top cover a. Most of the water is blocked by the baffle plate 4 and then falls back into the inner liner. A small portion of the water bypasses the baffle plate 4 and reaches the inner top wall of the cover 1. It then bounces off the inner top wall of the cover 1 and enters the venting channel 7. Water passing through the top of the venting channel 7 is blocked by the first baffle rib 3 and then falls down onto the baffle plate 4. It then flows to the outer edge of the baffle plate 4 and finally flows out of the venting channel 7 and falls back into the inner liner. Water passing through the lower part of the venting channel 7 is blocked by the second baffle rib 3. The water is blocked by the baffle 5, and then falls downward onto the baffle plate 4, then flows to the outer edge of the baffle plate 4, and finally flows out of the exhaust channel 7 and falls back into the inner liner; when the bottle is drying, the steam in the inner liner flows upward onto the top cover a, then enters the exhaust channel 7, and flows through the exhaust port 10 to the air outlet channel 8, and finally is discharged to the outside through the air outlet 15; in addition, some steam will come into contact with the baffle plate 4, the first baffle 3, the second baffle 5 and the guide rib 6, causing the steam to condense, and the condensate will fall back into the inner liner, thereby reducing the temperature of the discharged steam and preventing the discharged steam from scalding the user.
[0028] The cover 1 has an inner cavity 9 that connects to the inside of the inner liner. The baffle 4 is located inside the inner cavity 9 and is inclined downward from the center to the outer edge, so that the water falling on the baffle 4 will flow to the outer edge of the baffle 4.
[0029] The exhaust channel 7 is located inside the inner cavity 9, and the inner cavity 9 is connected to the exhaust channel 7. Steam and water in the inner liner enter the exhaust channel 7 through the inner cavity 9, and water flowing out of the exhaust channel 7 falls back into the inner liner through the inner cavity 9.
[0030] The top of the cover 1 is provided with an exhaust port 10, and the exhaust channel 7 is connected to the air outlet channel 8 through the exhaust port 10. The water baffle 4 covers the bottom of the exhaust port 10, and the area of the water baffle 4 is larger than the area of the exhaust port 10, which can prevent water sprayed onto the top cover a from entering the exhaust port 10.
[0031] The top of the cover 1 is provided with a recess 11, and the vent 10 is located at the bottom center of the recess 11. The recess 11 is located above the baffle plate 4, and the area of the recess 11 is larger than the area of the baffle plate 4. The recess 11 can also play a role in blocking water. A small amount of water will directly reach the recess 11 and then bounce back into the inner liner through the recess 11.
[0032] The second water-blocking rib 5 has a notch 12 at its top, and the lower part of the first water-blocking rib 3 is inserted into the notch 12 so that the first water-blocking rib 3 and the second water-blocking rib 5 are staggered vertically.
[0033] The water-blocking and venting assembly 2 includes a water-blocking component 13 and a venting component 14 connected to each other. The water-blocking component 13 is located in the inner cavity 9, and the venting component 14 is located in the recess 11.
[0034] The water-blocking and venting assembly 2 also includes a connector 16. The water-blocking component 13 is provided with a positioning post 17, and the venting component 14 is provided with a positioning hole 18. The positioning post 17 passes through the positioning hole 18. The connector 16 is provided with a first fixing hole 19, and the positioning post 17 is provided with a second fixing hole 20. After the screw passes through the first fixing hole 19, it is fastened to the second fixing hole 20 so that the venting component 14 is connected to the water-blocking component 13 through the connector 16.
[0035] The water-blocking component 13 includes a water-blocking plate 4 and a second water-blocking rib 5. The second water-blocking rib 5 is distributed in a cross shape on the water-blocking plate 4, and the first water-blocking rib 3 is annular so that the exhaust channel 7 is distributed in annularly. The exhaust port 10 is located inside the annularity of the first water-blocking rib 3. The notch 12 is distributed in annularly on the water-blocking component 13.
[0036] The guide rib 6 is set at the bottom of the exhaust component 14. The bottom of the guide rib 6 abuts against the bottom wall of the recess 11 so that the exhaust component 14 is pressed between the connector 16 and the cover 1, thereby fixing the entire water-blocking and exhaust assembly 2 on the cover 1. The guide rib 6 is U-shaped, and its U-shaped opening faces the cover 1 so that the air outlet channel 8 faces the cover 1. The U-shaped guide rib 6 makes the air outlet channel 8 U-shaped, and the U-shaped opening is the outlet of the air outlet channel 8.
[0037] There is a gap between the edge of the exhaust component 14 and the edge of the recess 11 to form an air outlet 15 that communicates with the outside world, and the air outlet channel 8 communicates with the air outlet 15.
