The other end of the adapter 22 opposite to the cleaning head 24 is detachably connected to the connector 14 of the grip 10. The inner wall of the adapter 22 is provided with two grooves 221 corresponding to the protruding strips 141e of the adapter 14, it should be noted that the protruding strips 141e and the grooves 221 are disposed in a corresponding relationship, and when the number of the protruding strips 141e is one, the number of the grooves 221 is also one. In addition, the adapter 22 has a notch 222 formed at an opening end connected to the connector 14.

The detaching unit 30 includes a control member 32 and an elastic member 34, which is a spring, disposed at one end of the grip lever 10, and a locking portion disposed on an inner wall of the connection tube 22. As shown in fig. 5 and 6, the control member 32 is a long plate and has a clamping portion formed by a protrusion 321 and a pressing portion formed by a protrusion 322 protruding from a surface thereof, as shown in fig. 7, a horizontal line L is defined to pass through the control member 32, the protrusion 322 and the protrusion 321 respectively have a first height H1 and a second height H2 based on the horizontal line L, wherein the first height H1 is greater than the second height H2, the protrusion 321 has an inclined pushing surface 321a, and a height of the control member 32 at a position below the horizontal line L increases gradually from the protrusion 322 to the protrusion 321. The long sides of the control member 32 are located below the horizontal line L and are biased against the protrusion 321, and each of the long sides has a side block 323 protruding outwards, and a tongue plate 324 protruding outwards from the short side of the control member is biased against the button 322. In addition, the control member 32 has a positioning groove 325 concavely formed from the bottom surface, and the knob 322 has a hollow 322a concavely formed from the bottom surface.

As shown in fig. 8 and 9, the side blocks 323 of the control member 32 are inserted into the grooves 141a of the connector 14 in alignment, and the tongue plate 324 of the control member 32 extends into the slot 141d of the connector 14, so that the control member 32 is located in the socket 141. At the same time, the positioning groove 325 of the control element 32 is configured with the positioning block 141b, so as to increase the stability of the control element 32 combined with the joint 14. The elastic member 34 is placed between the control member 32 and the joint 14 before the control member 32 is combined with the joint 14, one end of the assembled elastic member 34 abuts against the bottom wall of the counterbore 141c of the socket 141 of the joint 14, the other end abuts against the inner wall of the hollow portion 322a of the control member 32, the elastic force of the elastic member 34 causes the control member 32 to be lifted up with the end having the side block 323 as a fulcrum and the opposite end, and the lifted control member 32 abuts against the groove wall of the insertion groove 141d with the tongue plate 324 thereof, so that the control member 32 is not separated from the joint 14, and the control member 32 has a feature that the height of the part below the horizontal line L is gradually increased from the convex button 322 to the direction of the convex block 321, so that the control member 32 can have a larger pressing space at the part corresponding to the convex button 322.

The locking part of the disconnecting unit 30 is formed by a locking groove 36 formed by recessing from the inner wall of the connecting pipe 22, the locking groove 36 is close to the notch 222, the groove depth of the locking groove 36 increases from one side far away from the notch 222 to the direction of the notch 222, and the groove bottom of the locking groove 36 is obliquely matched with the oblique pushing surface 321a of the projection 321.

As shown in fig. 8 and 9, when the joint 14 at one end of the grip 10 is to be inserted into the adapter 22 of the cleaning unit 20, the protrusion 141e of the joint 14 is aligned with the groove 221 of the adapter 22 and slides into the groove 221, and the protrusion 141e and the groove 221 are configured such that the grip 10 and the cleaning unit 20 after the docking are not rotated relative to each other.

When the adapter 14 is inserted into the adapter 22, the protrusion 321 of the control member 32 first contacts the edge of the opening end of the adapter 22, and as the adapter 14 is further inserted toward the adapter 22, the control member 32, because the protrusion 321 has the relationship of the inclined pushing surface 321a, causes the end having the knob 322 to slightly sink and compress the elastic member 34 until the protrusion 321 completely enters the slot 36 of the adapter 22, and the protrusion 321 abuts against the slot wall of the slot 36, so that the grip 10 cannot be separated from the adapter 22. At the same time, the button 322 of the control member 32 is located outside the connecting tube 22 just after the notch 222, and the elastic force of the elastic member 34 can ensure that the protrusion 321 (i.e. the engaging portion) of the control member 32 can be reliably inserted into the engaging groove 36 (i.e. the engaging portion) before the control member 32 is not pressed. On the contrary, when the button 322 (i.e. the pressing portion) is pressed downward, the control member 32 with the two side blocks 323 as the supporting points drives the protrusion 321 to disengage from the slot 36, so that the grip lever 10 can be smoothly pulled away from the connection tube 22 to separate the grip lever 10 from the cleaning unit 20, and further, the cleaning unit with different functions can be replaced.

In the present embodiment, the control member 32 is provided with a clamping portion (i.e., the protrusion 321) for realizing the butt joint of the grip 10 and the cleaning unit 20 without being detachable, and a pressing portion (i.e., the protrusion 322) for realizing the separation of the grip 10 and the cleaning unit 20, which are separately provided, so as to improve the disadvantage that a single protrusion has both a clamping function and an unlocking function, which is inconvenient to hide and operate and may pinch the finger abdomen. Therefore, the utility model not only has simple and convenient operation, but also improves the use safety in the dismounting and replacing process.

The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications to the present invention as described and claimed should be included in the scope of the present invention.
