DETAILED DESCRIPTION

[0024] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings, and this embodiment does not constitute a limitation of the present invention. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0025] A borescope that facilitates secondary cleaning, such as Figure 1 As shown, the borescope body 1 includes a cleaning part 2 connected at one end and an operating part connected at the other end. The front end of the cleaning part 2 is fixedly connected to an endoscope lens 5 through a structure such as a thread or a screw. The endoscope lens 5 is inserted into the interior of the hose to observe the cleaning quality. The operating part is operated to perform secondary cleaning, thereby realizing observation and detection while corresponding cleaning.

[0026] like Figure 1 and Figure 2 As shown, a telescopic brush body 3 and a flushing liquid spraying member 4 are provided inside the cleaning portion 2, the telescopic brush body 3 is radially slidably connected inside the cleaning portion 2, a window corresponding to the extension of the telescopic brush body 3 is opened on the outside of the cleaning portion 2, the flushing liquid spraying member 4 is axially retracted in the borescope body 1, and the telescopic brush body 3 is driven to extend out of the window through its axial extension;

[0027] In some embodiments, a guide block is fixed in the cleaning part 2 to block one or both ends of the telescopic brush body 3 to limit the circumferential displacement of the telescopic brush body 3. The guide block can be further arranged to cooperate with the telescopic brush body 3 as a plug-in slot or a T-block T-slot to further improve the guiding effect; at least in the borescope body 1, there is a spray limit frame 12 at a position close to the cleaning part 2 and the operating part, and the flushing liquid spray part 4 enters the cleaning part 2 after passing through at least two spray limit frames 12 from the outer end to limit the flushing liquid spray part 4 to move only in the axial direction.

[0028] like Figure 1 As shown, the operating part includes an operating block 11, which is only connected to the borescope body 1 by sliding in the axial direction, and is internally connected to the flushing liquid spraying member 4. The axial displacement of the flushing liquid spraying member 4 in the borescope body 1 is driven by the movement of the operating block 11. In some embodiments, the operating block 11 can also directly control the on-off switch of the cleaning liquid in the flushing liquid spraying member 4 through the position before and after its movement through structures such as a travel switch;

[0029] An axial slide groove is provided on the outer periphery of the operating part, and a shift block is integrally connected to the outer side of the operating block 11, and the shift block extends out of the slide groove. A layer of friction protrusions is also connected to the outer side of the operating block 11 on both sides of the shift block. The shift block is moved to the two ends of the slide groove of the operating part, and its position at the corresponding end can be temporarily clamped by friction through the friction protrusion. The positions at the two ends can correspond to the position of the telescopic brush body 3 retracting into the cleaning part 2 and pushing the telescopic brush body 3 to extend; the above structure can also be replaced by a structure that is driven to retract by rotation, such as a thread, or any other driving structure that can control the axial movement of the flushing liquid spraying part 4.

[0030] like Figure 2 As shown, an inclined block 41 is fixed to the inner end of the washing liquid spraying member 4 near the telescopic brush body 3. When the washing liquid spraying member 4 is axially extended and retracted, the telescopic brush body 3 is pushed to extend outward from the cleaning portion 2. A plurality of injection ports 31 are passed through the telescopic brush body 3. The washing liquid spraying member 4 sprays the cleaning liquid outward through the injection ports 31.

[0031] In the present embodiment, a plurality of inclined blocks 41 are provided to stably push the two ends of the telescopic brush body 3 so that they can be pushed and moved together. The inclined direction of the inclined block 41 is that the front end is inclined along the side away from the telescopic brush body 3, so that when the flushing liquid spraying part 4 moves axially forward, it can push the telescopic brush body 3 to extend out of the cleaning part 2; the inclined direction of the inclined block 41 can also be set in the opposite direction, so that when the flushing liquid spraying part 4 moves axially backward, it pushes the telescopic brush body 3 outward; in some other embodiments, the inclined block 41 is directly set to an isosceles trapezoidal shape, so that the inclined surfaces on both sides can correspondingly push the telescopic brush body 3 outward.

[0032] like Figure 2 As shown, a plurality of corresponding brush body blocks 32 are provided at intervals on the inner side of the telescopic brush body 3, and the inclined block 41 is located at one end of the brush body block 32, or is moved to push the brush body block 32 outward; in this embodiment, a groove corresponding to the inclined block 41 is provided on the inner side of the telescopic brush body 3, and a brush body block 32 is formed on the corresponding side of the groove, and the inclined block 41 is located in the groove, or is moved to push the telescopic brush body 3 outward along the corresponding side of the groove.

[0033] like Figure 2 and Figure 3 As shown, one end of the flushing liquid spraying member 4 is located at the rear end of the borescope body 1, and is used to connect to the cleaning liquid pipe to pass the cleaning liquid. A main flow channel is provided in the flushing liquid spraying member 4 for the cleaning liquid to be transported forward;

[0034] In this embodiment, the liquid spray port of the flushing liquid spraying member 4 is located outside the inclined block 41, and the liquid spray port is connected to the main channel through a branch channel to realize the outward spraying of the cleaning liquid. After the inclined block 41 pushes the brush body block 32 outward, the spray direction of the liquid spray port thereon is aligned with the spray port 31 in the telescopic brush body 3, and the bristles and the tube wall to be cleaned are sprayed together. A plurality of small liquid ports can be opened in the telescopic brush body 3, so that the cleaning liquid overflowing in the cleaning part 2 can be sprayed out from the small liquid port and other positions.

[0035] like Figure 1 and Figure 2 As shown, the cleaning portion 2 is detachably connected to one end of the borescope body 1; specifically, the cleaning portion 2 and the end of the borescope body 1 are provided with external threads with opposite rotation directions, and are connected to the same connecting tube 8, and the inner circumferences of the two ends of the connecting tube 8 are respectively provided with corresponding internal threads with opposite rotation directions. The connecting tube 8 can simultaneously connect the cleaning portion 2 and the borescope body 1 on both sides when rotating, so that the cleaning portion 2 and the borescope body 1 do not rotate relative to each other when connected, avoiding the reciprocating twisting of the connecting line of the endoscope lens 5 or winding it around the outside of the flushing liquid spraying part 4, which may cause it to be easily damaged.

[0036] like Figure 3 As shown, an elastic member is further provided in the cleaning portion 2, and the elastic member drives the telescopic brush body 3 to retract radially into the cleaning portion 2; in this embodiment, the elastic member includes a connecting block 6 and a plurality of compression springs 61, the connecting block 6 is connected to the telescopic brush body 3, and the compression spring 61 abuts against a side of the connecting block 6 close to the telescopic brush body 3, pushing it to retract inward into the cleaning portion 2;

[0037] Specifically, a baffle 7 and a circuit sealing plate are fixed in the cleaning part 2. The circuit sealing plate separates a space on one side of the cleaning part 2 for connecting the circuit of the endoscope lens 5, and the space on the other side is used to connect the baffle 7, the connecting block 6 and the telescopic brush body 3 and other structures. The end of the borescope main body 1 can be pressed against the outside of the circuit sealing plate through a sealing strip to prevent the cleaning fluid from entering therein; one end of the compression spring 61 is connected to the connecting block 6, and the other end is connected to the inside of the baffle 7, and the connecting block 6 is pushed to abut against the outside of the circuit sealing plate, and the inner end of the flushing liquid spraying member 4 is inserted between the baffle 7 and the telescopic brush body 3.

[0038] like Figure 3As shown, elastic plates 62 are respectively connected to both sides of the connection block 6, and the inner side of the elastic plate 62 is connected to the limiting insert 63. Limiting grooves adapted to the limiting insert 63 are provided on both sides of the telescopic brush body 3. The elastic plate 62 extends outward from the position of the connection block 6 to the through-baffle 7, and is inserted into the corresponding side of the telescopic brush body 3 through the limiting insert 63 to achieve connection with the telescopic brush body 3 (the telescopic brush body 3 is installed inward from the outer window direction of the cleaning portion 2, and the elastic plate 62 is opened outward until the installation port is inserted inward into the limiting groove). The elastic plate 62 can also be replaced with a rigid one, and fixedly connected by screws or plugging (inserted and installed from one end of the cleaning portion 2 to the inner end);

[0039] In order to leave a gap between the telescopic brush body 3 and the baffle 7 to facilitate the insertion of the end of the washing liquid spraying member 4, two limit blocks 71 are fixedly connected to the side of the baffle 7 close to the telescopic brush body 3. The limit blocks 71 are arranged on the moving path of the telescopic brush body 3 to limit the telescopic brush body 3 outside the minimum spacing of the baffle 7. The inner end of the washing liquid spraying member 4 is inserted between the baffle 7 and the telescopic brush body 3 from the minimum spacing.

[0040] The telescopic brush body 3 includes a base 33 and a replacement brush 34. The replacement brush 34 is detachably connected to the outside of the base 33 by screws. Structures such as the brush body stopper 32 are located on the base 33. A threaded hole can be opened on the outside of the replacement brush 34 to facilitate screwing in the screw at this position to assist in pulling out the telescopic brush body 3 during disassembly.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions should also be deemed to fall within the protection scope of the technical solution of the present invention.
