This embodiment is an improved scheme based on embodiment 6, and the main structure thereof is the same as embodiment 6, and the improvement point is that: as shown in fig. 5, an end of the inflation tube 202 near the inflation cavity 103 is provided with a gas release assembly 207 for discharging gas in the front end airbag 303 and the rear end airbag 302 to the outside.

Example 8

This embodiment is an improved scheme based on embodiment 7, and the main structure thereof is the same as embodiment 7, and the improvement point is that: as shown in fig. 6, the air release assembly 207 includes a fixing member 2071 disposed on the pipe body of the cleaning pipeline 2, a first counter bore 2076 is formed at the center of one end of the fixing member 2071 facing the outside, the bottom of the first counter bore 2076 is communicated with the interior of the inflation tube 202 through a sliding channel 2072, a first piston body 2073 is slidably disposed in the sliding channel 2072, and the outer end of the first piston body 2073 is connected to a cap plate 2075 slidably disposed in a first counterbore 2076 by a compression spring, a first escape canal 2074 is disposed in the first piston body 2073, the outer end of the first escape canal 2074 penetrates through the cover plate 2075 and communicates with the outside, the inner end extends to the sidewall of the first piston body 2073, and is covered by the inner wall of the sliding channel 2072 when the compression spring is at the initial position, when the cover 2075 is pressed down, the inner end of the first escape duct 2074 is pressed into the inflation tube 202, thereby exhausting the gas inside the leading airbag 303 and the trailing airbag 302.

In this embodiment, when the inflation tube 202 inflates into the leading end airbag 303 and the trailing end airbag 302, the internal air pressure thereof is greater than the external standard air pressure, which pushes the first piston body 2073 to move outward, but due to the presence of the compression spring, the first piston body 2073 is always kept in the sliding channel 2072, and the first escape duct 2074 is kept in a blocked state; when the cover plate 2075 is pressed down, the cover plate 2075 drives the first piston body 2073 to slide towards the inflation tube 202, so that the inner end of the first air release duct 2074 is pressed into the inflation tube 202, the inflation tube 202 is conducted with the outside, and then the air in the front end airbag 303 and the tail end airbag 302 flows back to the outside through the inflation tube 202 and the first air release duct 2074, so that the front end airbag 303 and the tail end airbag 302 are contracted to be taken out conveniently.

Example 9

The present embodiment is another improvement scheme made on the basis of embodiment 6, and the main structure thereof is the same as embodiment 6, and the improvement point is that: as shown in fig. 5, the side wall of the cleaning solution chamber 102 has a solution injection pipe 104 for injecting a cleaning solution therein.

Example 10

The present embodiment is another improvement scheme made on the basis of embodiment 6, and the main structure thereof is the same as embodiment 6, and the improvement point is that: as shown in fig. 5, in order to prevent the cleaning solution in the cleaning solution pipeline 201 from flowing back, a one-way liquid passing assembly 204 is disposed at a connection position of the cleaning solution pipeline 201 and the partition plate 101, the one-way liquid passing assembly 204 has the same structure as the first one-way ventilation assembly 105 and the second one-way ventilation assembly 203, as shown in fig. 7, the one-way liquid passing assembly 204 includes an inner tube 2042 which is disposed in the cleaning solution pipeline 201 and has two open ends, an outer portion of the inner tube 2042 is fixed on an inner wall of the cleaning solution pipeline 201 through an annular sleeve 2041, the inner tube 2042 is coaxial with the cleaning solution pipeline 201, so as to form a cleaning solution passage inside the inner tube 2042, a flap 2043 is rotatably disposed on a downstream side of the inner tube 2042 along a flow direction of the cleaning solution, and the flap.

In this embodiment, a downstream end of the inner tube 2042 protrudes out of the annular sleeve 2041 to form a bayonet structure, the pin is disposed on an end surface of the annular sleeve 2041, and the flap 2043 is attracted to the inner tube 2042 by the annular magnet 2044 disposed at an end of the inner tube 2042 at an initial position, and blocks a cleaning solution passage formed by the inner tube 2042; in order to ensure that the flap 2043 can be smoothly restored to the initial position, a torsion spring can be sleeved outside the pin shaft, and the flap 2043 can be restored to the initial position after being flushed away by the cleaning solution by utilizing the restoration property of the torsion spring.

In this embodiment, the one-way liquid passage assembly 204 is identical in construction to the first one-way vent assembly 105 and the second one-way vent assembly 203, except that the annular sleeve of the first one-way vent assembly 105 is secured to the sidewall of the inflation lumen, as shown in FIG. 8, and the annular sleeve of the second one-way vent assembly 203 is secured within the inflation tube 202, as shown in FIG. 9.
