[0022] As Figures 1-4As shown, the present application provides a kind of endoscope cleaner of intracavitary sealing fluid circulation cleaning, including sealing cover 10, fixed seat 20, inner sleeve 30 and outer sleeve 40, wherein the sealing cover 10 between fixed seat 20 is connected by reverse buckle 11 being arranged on sealing cover 10 and hidden clamping groove 21 being arranged on fixed seat 20;Inner sleeve 30 is lifted by outer sleeve 40 upwards, so that inner sleeve 30 is embedded in the middle hole connected in fixed seat 20;Outer sleeve 40 and fixed seat 20 are connected by the multiple clamping teeth 41 of the top of outer sleeve 40 and the clamping groove on fixed seat 20.The reverse buckle 11 is arranged on the sealing cover 10, and the clamping structure of the reverse buckle 11 faces outward, while the hidden clamping groove 21 is arranged on the fixed seat 20, and the clamping groove structure of the hidden clamping groove 21 faces inward, so that the reverse buckle 11 faces the hidden clamping groove 21 from inside to outside, thereby overcoming the common buckle from outside to inside buckling, which cannot provide strong locking force (if the locking force is too large, the conventional buckle will expand outward and loosen) ;And the structure of hidden clamping groove 21 is inwardly protruding on fixed seat 20, and space is reserved on the inside of hidden clamping groove 21 to allow the reverse buckle 11 to deform inwardly and connect with hidden clamping groove 21.

[0023] The two sides of the sealing cover 10 are provided with downwardly extending ear plates 12, and the reverse buckle 11 is located at the lower end of the ear plate 12.The ear plate 12 is in the shape of an inverted trapezoid, integrally connected to the two side edges of the sealing cover 10, and arranged vertically downward, wherein the thickness of the ear plate 12 is much larger than the size of the reverse buckle 11, thereby providing greater connecting force.The overall ear plate 12 is in the structure of an arc plate, thereby having better deformation resistance.

[0024] The fixed seat 20 is provided with a recessed mounting groove 22 corresponding to the connecting position of the ear plate 12;A sunken accommodating space 23 is provided at the bottom of the mounting groove 22, and a through hole 24 is provided at the bottom of the accommodating space 23, which penetrates the accommodating space 23 horizontally, and the through hole 24 and the inner wall of the accommodating space 23 form a hidden clamping groove 21 bent inwardly;Wherein, the two sides of the hidden clamping groove 21 are connected with the main body structure of the fixed seat 20, so that the two sides of the hidden clamping groove 21 can provide pulling force to the hidden clamping groove 21.The position of the through hole 24 is below the hidden clamping groove 21, and through the structural design of the through hole 24, the hidden clamping groove 21 can be formed on the fixed seat, thereby overcoming the difficulty of processing the inward clamping groove structure on the outer surface of the column (non-column hole position), and at the same time, the two sides of the hidden clamping groove 21 remain integrally connected with the fixed seat 20, thereby providing pulling force to the hidden clamping groove 21, and ensuring the structural strength of the hidden clamping groove 21.

[0025] The mounting groove 22 and the ear plate 12 are adaptively connected and are both trapezoidal in shape.

[0026] The lower end of the sealing upper cover 10 is further provided with a plurality of guide connecting columns 13, and the corresponding positions of the upper end surface of the fixing seat 20 are respectively provided with guide connecting holes 25, and the guide connecting columns 13 are connected into the guide connecting holes 25 in a position connection manner.

[0028] The fixing seat 20 is provided with a water suction port 26, a water inlet port 27 and an exhaust port 28, a water suction valve 26a is arranged at the water suction port 26, a water inlet valve 27a is arranged at the water inlet port 27, and an exhaust valve 28a is arranged at the exhaust port 28, and the water suction port 26, the water inlet port 27 and the exhaust port 28 are respectively communicated with the inner sleeve 30 through independent channels in the fixing seat 20. The exhaust port 28 is located below one of the hidden clamping grooves 27, thereby avoiding the hidden clamping groove 27; and the water suction port 26 and the water inlet port 27 are directly designed on the top surface of the fixing seat and are staggered with the two ear plates 12; the water suction port 26 and the water inlet port 27 are designed with guide connecting holes 25 between the two ear plates, thereby making the overall structural layout of the fixing seat reasonable and ensuring the overall structural strength.

[0029] The inner sleeve 30 is provided with a cross valve 30a at the end thereof, and the cross valve 30a is located inside the outer sleeve 40.

[0030] The top end of the inner sleeve 30 is a flat surface and is in abutment sealing with the stepped structure in the fixing seat 20.

[0031] The endoscope cleaner for cleaning a cavity by sealing fluid circulation provided by the application further comprises a sealing cap 51 and a gas blocking valve 52, which are pressed and connected in the fixing seat 20 by the sealing upper cover 10.

[0032] The endoscope cleaner for cleaning a cavity by sealing fluid circulation provided by the application has a large reduction in the number of parts of the overall structure, and the main components are connected through a buckle structure, thereby avoiding the problems of low welding process efficiency and high cost, and ensuring the sealing performance after connection, and improving the stability and structural strength of the connection through reasonable structural layout.
