[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Specific implementation examples are given below.

[0017] Please see Figures 1-4 This utility model provides a cleaning brush with an interchangeable brush head, including an outer cylinder 1 and a cleaning brush head 101. A locking component is provided on the top of the outer cylinder 1, and the locking component includes a drive rod 301. A quick-release component is provided inside the outer cylinder 1. The quick-release assembly includes a fixed cylinder 201 fixed inside the outer cylinder 1, a sliding inner cylinder 202 sleeved on the surface of the fixed cylinder 201, a top plate 205 slidably connected to the surface of the fixed cylinder 201, a base plate 204 fixedly connected to the bottom of the fixed cylinder 201, an arc-shaped slot on the surface of the outer cylinder 1, a drive button 203 slidably connected within the arc-shaped slot, the drive button 203 fixed to one side of the sliding inner cylinder 202, and first circular holes on both sides of the outer cylinder 1, with ball bearings 207 disposed within the first circular holes. The outer cylinder 1 has slots on both sides that match the size of the ball bearing 207. During operation, the locking assembly on the top of the outer cylinder 1 locks the outer cylinder 1 and the cleaning brush head 101 after replacement. The top of the inner cavity of the outer cylinder 1 is rigidly connected to the fixed cylinder 201, providing installation space and guidance for subsequent components. The sliding inner cylinder 202, which is fitted on the surface of the fixed cylinder 201, is located inside the outer cylinder 1 and is in close contact with the inner wall of the outer cylinder 1. The top plate 2 is slidably connected to the surface of the fixed cylinder 201. 05, located inside the sliding inner cylinder 202, allows the top plate 205 to move along the axial direction of the sliding inner cylinder 202, ensuring the stability of the top plate 205 during movement and preventing offset or shaking. The base plate 204 at the bottom of the fixed cylinder 201 acts as a limit, preventing damage to the device caused by excessive movement of the top plate 205. The drive button 203 in the arc-shaped slot on one side of the outer cylinder 1 is directly connected to one side of the sliding inner cylinder 202. During operation, pressing down on the drive button 203 will activate the mechanism. The sliding inner cylinder 202 moves synchronously, thereby driving the inner top plate 205 to move synchronously along the axial direction of the fixed cylinder 201. When the sliding inner cylinder 202 moves down, the balls 207 on both sides of the outer cylinder 1 contact the sliding inner cylinder 202, and the sliding inner cylinder 202 has slots on both sides that match the balls 207. At this time, the cleaning brush head 101 and the outer cylinder 1 are in an unlocked state. When the force on the drive button 203 is removed, the two balls 207 reset and return to the first circular hole, thus locking the cleaning brush head 101.

[0018] Through the linkage structure of the drive button 203, the sliding inner cylinder 202 and the ball bearing 207, unlocking only requires pressing down on the drive button 203, and locking requires no additional operation. Removing the force will automatically reset the device. The entire process can be completed with one hand without the need for tools, making it suitable for different users. It significantly shortens the brush head replacement time and improves cleaning efficiency.

[0019] Furthermore, such as Figure 2 and Figure 4As shown, the locking assembly includes a drive rod 301 rotatably connected inside the fixed cylinder 201. A locking block 302 is fixedly attached to the bottom of the drive rod 301. A U-shaped support frame 303 is fixedly attached to the top of the cleaning brush head 101. Connecting rods 304 are fixedly attached to both sides of the U-shaped support frame 303. Rollers 305 are rotatably connected to the surfaces of the two connecting rods 304. During operation, the drive rod 301 in the locking assembly is rotatably connected inside the fixed cylinder 201. The drive rod 301 is an important driving component in the locking assembly. The locking block 302 at the bottom of the drive rod 301 has a locking effect. The U-shaped support frame 303 at the top of the cleaning brush head 101 provides installation space for subsequent components. The connecting rods 304 on both sides of the U-shaped support frame 303 provide an axial direction for the movement of the rollers 305, allowing the rollers 305 to rotate around the connecting rods 304.

[0020] After replacing the cleaning brush head 101, press down on the outer cylinder 1. The locking block 302 at the bottom of the drive rod 301 will engage between the two rollers 305, achieving a secure lock through the clamping of the rollers 305. To unlock, simply rotate the drive rod 301, causing the locking block 302 to rotate synchronously and adjust its angle, thus disengaging from between the two rollers 305 and completing the unlocking process.

[0021] Furthermore, such as Figure 2 As shown, a spring 206 is sleeved on the surface of the fixed cylinder 201. The spring 206 is located between the top plate 205 and the bottom plate 204. During operation, when the sliding inner cylinder 202 moves down, the spring 206 is compressed and will contract. When the downward pressure on the sliding inner cylinder 202 is removed, the spring 206 releases its elasticity and returns to its original state. Under its elastic force, it can drive the sliding inner cylinder 202 to quickly reset, ensuring efficient response of the locking action.

[0022] Furthermore, such as Figure 4 As shown, the size of the locking block 302 matches the gap between the two rollers 305. During operation, the drive rod 301 moves the locking block 302 at the bottom downwards. Since the size of the locking block 302 perfectly matches the gap between the two rollers 305, the locking block 302 will fit precisely between the two rollers 305, firmly restricting the locking block 302 within the gap, thereby achieving rigid locking between the outer cylinder 1 and the cleaning brush head 101, ensuring that there is no relative displacement between the two during the cleaning process.

[0023] Furthermore, such as Figure 2 As shown, the outer diameter of the top plate 205 matches the inner diameter of the sliding inner cylinder 202. During operation, the top plate 205 and the sliding inner cylinder 202 are designed to fit each other, ensuring that the top plate 205 can always move smoothly along the axial direction of the sliding inner cylinder 202 without any deviation or shaking, thus ensuring the accuracy and stability of the component movement.

[0024] Furthermore, such as Figure 2As shown, a knob is fixed to the top of the drive rod 301. During operation, the knob provides a convenient fulcrum for the operator to apply force. The drive rod 301 can be easily driven to rotate by rotation, which greatly reduces the operational intensity of the unlocking action and improves the ease of use.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
