Description

Technical Field

[0001] The utility model relates to the technical field of nursing equipment, in particular to an air-pollution separation device for a nursing machine. Background Art

[0002] The Care Machine is a new type of shampooing and bathing aid. It is a portable product specially designed for the elderly, disabled, and others to clean their hair and body. The bathing system design is suitable for hospitals, nursing homes, community service centers, and homes.

[0003] During operation, the intelligent bathing and nursing machine's showerhead needs to both spray clean water and recycle wastewater, so the negative pressure environment inside the machine is connected to the sewage tank. When the negative pressure fan operates, the showerhead generates negative pressure, causing wastewater to enter the sewage tank through a pipe. This in turn indirectly draws water vapor from the sewage tank into the fan, potentially causing electrical failures and compromising product safety. Therefore, designing an air-to-waste separation device for the machine is essential. Utility Model Content

[0008] The water vapor maze channel is in the form of a single-channel maze with a square coverage area. Its inlet is arranged on the side and the outlet is arranged on the center side. The entire path is in a spiral style, and the inlet and outlet are perpendicular to the maze.

[0009] The partition of the water vapor maze channel is made of one-piece injection molding, and is surrounded by a maze-shaped channel by a square outer partition and an inner partition. The partition, the upper pressure plate and the fixed plate form a sealed channel. The upper end of the partition is in contact with the upper pressure plate, and the lower end of the partition is in contact with the upper surface of the fixed plate.

[0010] Furthermore, the water vapor baffle is fixed to the lower end of the fixed plate by three screws, and the water vapor maze channel is fixed to the upper end of the fixed plate by four screws and sealing washers and glass glue.

[0011] The water vapor baffle is a circular plate with a high middle and low sides, which is protected on the inlet of the water vapor maze channel and plays a role in preventing most of the sewage in the sewage tank from splashing into the air suction port.

[0012] The fan motor is placed in the fan box and fixed with screws. Its air suction channel is connected with the outlet of the water vapor maze channel. The fan box and the upper pressure plate are installed together and fixed with four screws.

[0013] Furthermore, a sponge is attached to the lower end of the upper pressure plate and installed in conjunction with the water vapor maze channel, and finally fastened with 4 screws to complete the installation.

[0020] The following is combined with Figure 1-3 The utility model is further described as follows:

[0021] like Figure 1-3The shown embodiment shows an air-pollution separation device for a nursing machine, which includes a water vapor baffle 1, a fixed plate 2, a water vapor maze channel 6, an upper pressure plate 3, and a fan box 4. The fixed plate 2 is fixedly installed directly above the sewage tank. The fixed plate can also be a part of the upper top plate of the sewage tank. Its main purpose is to support the installation and fixation. It is provided with an air suction port 5, and a water vapor baffle 1 is provided at the air suction port. A gap is provided between the water vapor baffle and the air suction port and covers the air suction port 5. The gap is used to pass airflow. The water vapor maze channel 6 is provided between the fixed plate 2 and the upper pressure plate 3. One end of the water vapor maze channel is provided with an inlet 9 connected to the air suction port, and the other end is provided with an outlet 10 connected to the fan 8. A sponge is provided in the water vapor maze channel.

[0022] Furthermore, the sponge is a water-absorbing sealing sponge, the area of ​​which is greater than or equal to the area of ​​the water vapor maze channel, and is fixedly arranged between the water vapor maze channel and the upper pressure plate, and can effectively absorb the water vapor entering the water vapor maze channel.

[0023] The water vapor maze channel is in the form of a single-channel maze with a square coverage area. Its inlet 9 is arranged on the side and the outlet 10 is arranged on the center side. The entire path is in a spiral style, and the inlet and outlet are perpendicular to the maze.

[0024] The partition 11 of the water vapor maze channel is made of one-piece injection molding, and is surrounded by a maze-shaped channel by a square outer partition and an inner partition. The partition, the upper pressure plate, and the fixed plate form a sealed channel. The upper end of the partition is in contact with the upper pressure plate, and the lower end of the partition is in contact with the upper surface of the fixed plate. The upper pressure plate has a circular hole as the maze exit 10, and the fixed plate has a circular hole as the maze entrance 9.
