Description

Technical Field

[0001] The present application relates to the technical field of cleaning tools, and in particular to a cleaning brush that is easy to operate. Background Art

[0002] In the cleaning field, cleaning brushes are a common cleaning tool and are widely used in cleaning operations in various scenarios. However, traditional cleaning brushes have many shortcomings in terms of controllability and functionality, which limit their efficiency and user experience.

[0003] Traditional cleaning brushes typically only feature a simple rotation function, with the brush head driven directly by a motor. While this design can meet basic cleaning needs to a certain extent, its controllability and flexibility are insufficient when faced with complex and varied cleaning tasks. For example, when it comes to controlling the rotation direction of the brush head, traditional cleaning brushes often lack sufficient response. This makes it difficult for users to achieve efficient and precise cleaning operations in actual use, affecting the overall cleaning effect and user experience. Utility Model Content

[0004] In view of this, the present application provides a cleaning brush that is easy to operate, can adjust different rotation angles, and provide cleaning liquid as needed to meet more environmental cleaning needs.

[0005] The present application provides a conveniently operated cleaning brush, which comprises:

[0006] Brush head;

[0007] The head assembly includes a driving member, a driving end of which is connected to the brush head and can drive the brush head to rotate;

[0008] a body assembly, rotatably connected to the head assembly in an axial direction, the body assembly comprising a housing and a first control circuit, a liquid storage box, and a water pump located within the housing, the first control circuit being electrically connected to the driving member and the water pump, the water pump being used to drive the liquid in the liquid storage box to the brush head;

[0009] The handle assembly is connected to the body assembly. A second control circuit is provided in the handle assembly. The second control circuit is signal-connected to the first control circuit.

[0010] By adopting the above technical solution, a drive element (such as a motor) outputs power through its drive end, driving the brush head to rotate and clean the surface of an object. The head assembly and the body assembly are connected axially via a rotation mechanism (such as a bearing or a rotating hinge), allowing the body assembly to rotate to a certain extent relative to the head assembly to accommodate cleaning needs at different angles. A liquid reservoir is located within the body assembly to store cleaning liquid, and a water pump is used to pump the liquid from the reservoir to the brush head, allowing precise delivery of the liquid from the reservoir to the brush head according to cleaning needs. The second control circuit is located in the handle assembly and is connected to the first control circuit via signals, enabling remote control and status monitoring. This dual-circuit design improves operational convenience and safety. The conveniently operated cleaning brush of this application integrates a rotation mechanism, a liquid supply system, and a control circuit to achieve efficient, flexible, and convenient cleaning operations, meeting diverse cleaning needs.

[0011] In some embodiments, the head assembly is slidably connected to a knob along the axial direction, and the knob is detachably connected to the housing; when the knob is disconnected from the housing, the head assembly can rotate relative to the body assembly, and when the knob is in an engaged state with the housing, the head assembly cannot rotate relative to the body assembly.

[0012] In some embodiments, one end of the head assembly is provided with a shaft or hole rotatably connected to the housing, and an elastic member is connected between the knob and the other end of the head assembly, and the elastic member drives the knob away from the head assembly and moves toward the engaging direction.

[0013] By adopting this technical solution, when the knob is pressed or rotated to the unlocked position, the elastic member is compressed or deformed, adjusting the rotation angle of the handpiece assembly. When the knob is released, the elastic member returns to its original shape, pushing the knob back to the engaged position, achieving automatic locking or positioning. This prevents the angle of the cleaning brush from changing due to misoperation or external interference, and enhances the stability of the cleaning brush.

[0014] In some embodiments, the knob includes a first locking structure, and the housing is provided with a second locking structure. When the knob is disconnected from the housing, the first locking structure is rotationally connected to the housing. When the knob is in a locked state with the housing, the first locking structure and the second locking structure are engaged.

[0015] In some embodiments, the first engaging structure includes protrusions / grooves spaced apart along the circumference of the knob, and the second engaging structure includes grooves / protrusions that cooperate with the protrusions / grooves.

[0016] By adopting the above technical solution, the knob is provided with a first engaging structure comprising protrusions or grooves spaced along the circumference of the knob. The shape, size, and number of these protrusions or grooves can be designed according to actual needs. The housing is provided with a second engaging structure comprising grooves or protrusions that mate with the protrusions or grooves on the knob. These grooves or protrusions match the shape, size, and number of the protrusions or grooves on the knob to ensure a tight engagement between the two. When the knob is disconnected from the housing, a certain gap is maintained between the first engaging structure and the housing, allowing the knob to rotate freely relative to the housing, allowing the user to adjust the position and angle of the knob as needed. When the knob is rotated to a specific position and engaged with the housing, the protrusions or grooves in the first engaging structure tightly engage with the grooves or protrusions in the second engaging structure, forming a securely locked state. This locked state prevents the knob from rotating without operation, thereby improving the stability and safety of the cleaning brush.

[0017] In some embodiments, the housing includes an upper housing and a lower housing, and the upper housing and the lower housing are buckled together to form a complete second snap-fit ​​structure.

[0018] By adopting the above technical solution, the upper and lower shells are fastened together using clips, screws, or other fastening methods. Once fastened together, the two shells form a complete housing. During the fastening process, the upper and lower shells butt against each other, forming a complete second fastening structure. This design not only facilitates processing and assembly, but also ensures the stability and reliability of the fastening structure between the knob and the housing.

[0019] In some embodiments, a side cover is further included, and a third snap-fitting structure that cooperates with the second snap-fitting structure is provided on the side cover.

[0020] By adopting the above technical solution, the side cover can buckle the upper shell and the lower shell together, thereby improving the reliability of the connection between the upper shell and the lower shell, and at the same time improving the integrity and aesthetics of the connection between the upper shell and the lower shell.

[0021] In some embodiments, the head assembly includes a fixed shell and a fixed cover fixedly connected to the fixed shell, the driving member is located in the fixed shell, and the driving end of the driving member passes through the fixed cover and is detachably connected to the brush head.

[0022] In some embodiments, a water outlet pipe is further included, which is connected to the liquid storage box through the water pump. One end of the water outlet pipe away from the water pump passes through the fixed cover and is connected to the fixed cover. The casing is provided with a water injection hole connected to the liquid storage box.

[0023] In some embodiments, the brush head is provided with a water hole and bristles, and the liquid output by the water outlet pipe can pass through the water hole and be introduced into the bristle end.

[0024] By adopting the above technical solution, the brush head is provided with a water hole and bristles. The water hole is used to receive the liquid output by the water outlet pipe. The liquid is introduced into the bristle end through the water hole and works together with the bristles to achieve a cleaning effect. The detachable connection design between the brush head and the drive component allows users to replace brush heads of different shapes or materials according to different cleaning tasks, improving the applicability and flexibility of the cleaning brush. The water injection hole design on the housing allows users to add cleaning liquid to the liquid reservoir at any time without disassembling the head assembly, which improves the convenience of operation.

[0025] In summary, this application has at least one of the following beneficial technical effects:

[0026] 1. The conveniently controlled cleaning brush of the present application has a second control circuit located in the handle assembly and connected to the first control circuit via a signal, thereby enabling remote wireless control and improving the convenience of control.

[0027] 2. The conveniently controlled cleaning brush of the present application has an adjustable angle of the head assembly and can also be fixed at that angle through a snap-fit ​​structure, thereby improving the convenience and adaptability of cleaning.
