Description
Technical Field
[0001] This utility model relates to the field of cleaning tools, and in particular to an electric cleaning brush with a convenient replaceable handle. Background Technology
[0002] With social development and people's living standards improving, the use of cleaning brushes is becoming more and more widespread, especially electric cleaning brushes. As an electric cleaning tool, they play a very important role in production and daily life and are widely used in various industries such as industry, agriculture, the service sector, and households.
[0003] A common electric cleaning brush includes a handle, a brush body connected to the handle, and a brush head detachably connected to the other end of the brush body. The brush body is equipped with a motor and a reducer, and the brush head is connected to the reducer. The handle contains a battery and a circuit board that are electrically connected to the motor. The motor is powered by the battery and drives the reducer through the circuit board to rotate the brush head, thereby performing cleaning operations using the brush head. For example, the Chinese utility model patent "An Electric Cleaning Brush" with patent number CN202023264105.8 (authorization announcement number CN214127443U) is disclosed.
[0004] However, when the battery or circuit board in the aforementioned electric cleaning brush fails and cannot drive the brush head to rotate normally, the handle and the battery and circuit board inside cannot be replaced because the handle and the main body of the cleaning brush are one piece. The entire electric cleaning brush must be replaced, which increases the economic burden on consumers. Summary of the Invention
[0005] The technical problem to be solved by this utility model is to provide an electric cleaning brush with a convenient handle replacement, in view of the above-mentioned existing technology.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problem is: an electric cleaning brush with a convenient handle replacement, comprising:
[0007] The cleaning brush body contains a motor, and the power output end of the motor is equipped with a brush head. When the motor drives the brush head to rotate, the brush head can perform cleaning operations.
[0008] A handle, wherein a battery for powering the motor is disposed within the handle;
[0009] The feature is that the handle is detachably connected to the cleaning brush body, the handle is provided with a first terminal for electrical connection to the battery, and the cleaning brush body is provided with a second terminal for electrical connection to the motor. When the handle is connected to the cleaning brush body, the battery and the motor are electrically connected by means of the insertion of the first terminal and the second terminal.
[0010] To facilitate the connection of the first and second terminals, preferably, the handle has a connecting portion for connecting to the cleaning brush body. The first terminal is located at the end of the connecting portion, and correspondingly, the cleaning brush body has a receiving cavity for receiving the connecting portion, with the second terminal located at the bottom of the receiving cavity. This ensures that the first and second terminals are coaxial when the connecting portion is inserted into the receiving cavity, facilitating their connection. Simultaneously, it protects the first and second terminals within the receiving cavity, preventing breakage due to radial shearing forces during use.
[0011] To maintain the connection between the handle and the cleaning brush body during use, a connector is preferably included that connects the receiving cavity and the connecting part, keeping them connected. This connector ensures the connection between the receiving cavity and the connecting part, preventing the handle and the cleaning brush body from detaching during use.
[0012] To allow for detachable connection between the receiving cavity and the connecting part, preferably, the connector includes a first end constrained on the cleaning brush body and a second end connected to the connecting part. The second end is provided with an internal thread, and the connecting part is correspondingly provided with an external thread. The receiving cavity and the connecting part are threadedly connected by the engagement of the internal and external threads. This threaded connection allows for detachable connection of the connector and the connecting part. When the engagement of the internal and external threads is released, the connector is detached from the connecting part. At this point, by applying a counterforce to the handle and the cleaning brush body, the engagement of the first and second terminals is released, thereby detaching the handle and the cleaning brush body; or the handle and the cleaning brush body are connected by the engagement of the first and second terminals, and the connection is maintained by the engagement of the internal and external threads.
[0013] To constrain the first end of the connector to the cleaning brush body, preferably, the cleaning brush body is provided with at least two outwardly protruding ribs spaced apart circumferentially, and the inner wall of the first end of the connector has a protruding ring that abuts against the ribs and constrains the connector to the cleaning brush body. Thus, a constraint is formed between the ribs and the ring, thus constraining the connector to the cleaning brush body. When the ribs and ring abut, further movement of the connector is restricted, preventing the connector from detaching from the cleaning brush body and thus rendering its function of connecting the handle and the cleaning brush body ineffective.
[0014] To facilitate the storage of the electric cleaning brush, preferably, a hanging rope is provided at the end of the handle away from the connecting part. When the electric cleaning brush is not in use, it can be suspended by the hanging rope.
[0015] To further facilitate the connection between the first terminal and the second terminal, preferably, the connecting part is provided with a positioning protrusion, and the receiving cavity is provided with a positioning groove that cooperates with the positioning protrusion.
[0016] Alternatively, the receiving cavity may be provided with a positioning protrusion, and the connecting part may be provided with a positioning groove that cooperates with the positioning protrusion.
[0017] The positioning is prevented by the cooperation of the positioning protrusion and the positioning groove. The state in which the positioning protrusion is aligned with the positioning groove is the state in which the first terminal is aligned with the second terminal. The positioning protrusion is inserted into the positioning groove, which means that the first terminal is inserted into the second terminal.
[0018] To facilitate the opening and closing of the electric cleaning brush, preferably, a circuit board electrically connected to the battery is also provided inside the handle. The circuit board has a button for controlling the motor's opening and closing, and this button is exposed on the outer surface of the handle. Positioning the button on the handle allows for easy opening and closing of the electric cleaning brush while holding the handle, and enables one-handed operation, making it convenient to use.
[0019] Compared with the prior art, the advantages of this utility model are:
[0020] 1. The handle of this electric cleaning brush is detachably connected to the brush body via the connection of the first and second terminals. The handle and its battery, and the brush body and its motor are modularized, allowing selection of the brush body or handle according to actual cleaning needs. For example, one brush body can be equipped with multiple handles for easy replacement after the battery is depleted, meeting long-term cleaning needs; or, one battery can be equipped with multiple brush bodies, so that only the brush body needs to be replaced when cleaning in different environments.
[0021] 2. The modular design allows for individual replacement of any damaged module, reducing repair and replacement costs for consumers. Furthermore, the combination of the first and second terminals enables quick disassembly and installation, facilitating replacement.
[0022] 3. The detachable connection between the handle and the cleaning brush body allows manufacturers to package the brush in the detached state, reducing packaging costs, as well as storage and transportation costs. Attached Figure Description

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0032] like Figure 1-8 The image shown is a preferred embodiment of the present invention.
[0033] See Figure 1-3This embodiment of an electric cleaning brush with a replaceable handle includes a cleaning brush body 1 and a handle 3 detachably connected to the cleaning brush body 1. The cleaning brush body 1 houses a motor 5, and the power output end of the motor 5 has a brush head 2. When the motor 5 drives the brush head 2 to rotate, the brush head 2 can perform cleaning operations. The handle 3 houses a battery 4 for supplying power to the motor 5. Since the cleaning brush body 1 and the handle 3 are detachably connected, a detachable connection is also required between the battery 4 in the handle 3 and the motor 5 in the cleaning brush body 1. Therefore, this embodiment has a first terminal 31 on the handle 3 for electrical connection to the battery 4, and a second terminal 11 on the cleaning brush body 1 for electrical connection to the motor 5. In this embodiment, the first terminal 31 is a male plug and the second terminal 11 are used. When the handle 3 is connected to the cleaning brush body 1, the battery 4 is electrically connected to the motor 5 by means of the insertion of the first terminal 31 and the second terminal 11. This design modularizes the handle 3 and its internal battery 4, and the cleaning brush body 1 and its internal motor 5. It allows selection of either the cleaning brush body 1 or the handle 3 based on actual cleaning needs. For example, one cleaning brush body 1 can be configured with multiple handles 3 for easy replacement after the battery 4 is depleted, meeting long-term cleaning requirements; or, one battery 4 can be configured with multiple cleaning brush bodies 1, so only the cleaning brush body 1 needs to be replaced when cleaning in different environments. For consumers, if any module is damaged, it can be replaced individually, reducing repair and replacement costs. Furthermore, the cooperation between the first terminal 31 and the second terminal 11 enables quick disassembly and installation, facilitating replacement. For manufacturers, the electric cleaning brush can be packaged in its detached state, reducing packaging costs, as well as storage and transportation costs.
[0034] The following describes the specific connection structure between the cleaning brush body 1 and the handle 3.
[0035] See Figure 4-6 The handle 3 has a connecting portion 32 for connecting to the cleaning brush body 1. A first terminal 31 is located at the end of the connecting portion 32. The cleaning brush body 1 has a receiving cavity 12 for receiving the connecting portion 32. A second terminal 11 is located at the bottom of the receiving cavity 12. When the connecting portion 32 is inserted into the receiving cavity 12, it ensures that the first terminal 31 and the second terminal 11 are coaxial, facilitating the connection of the first terminal 31 and the second terminal 11. Simultaneously, it protects the first terminal 31 and the second terminal 11 within the receiving cavity 12, preventing breakage due to radial shear force during use. To further facilitate the connection of the first terminal 31 and the second terminal 11, a foolproof structure is designed on the receiving cavity 12 and the connecting portion 32, as detailed in [reference needed]. Figure 8The connecting part 32 is provided with a positioning protrusion 34, and the receiving cavity 12 is provided with a positioning groove 14 that cooperates with the positioning protrusion 34. The positioning protrusion 34 and the positioning groove 14 cooperate to prevent misalignment. The state in which the positioning protrusion 34 is aligned with the positioning groove 14 is the state in which the first terminal 31 is aligned with the second terminal 11. The positioning protrusion 34 is inserted into the positioning groove 14, which means that the first terminal 31 is inserted into the second terminal 11.
[0036] In order to detachably connect the handle 3 and the cleaning brush body 1, and to maintain the connection between the handle 3 and the cleaning brush body 1 during use of the electric cleaning brush, the electric cleaning brush also includes a connector 6 that connects the receiving cavity 12 and the connecting part 32 and maintains the connection between them. See Figure 7 The connector 6 includes a first end 6a constrained on the cleaning brush body 1 and a second end 6b threadedly connected to the connecting portion 32. Specifically, the cleaning brush body 1 is provided with at least two protruding ribs 13 spaced apart circumferentially. A ring 62 protrudes from the inner wall of the first end 6a of the connector 6. The ring 62 abuts against the ribs 13 and constrains the connector 6 on the cleaning brush body 1. The second end 6b of the connector 6 is provided with an internal thread 61, and the connecting portion 32 is provided with an external thread 33. The receiving cavity 12 and the connecting portion 32 are threadedly connected by the cooperation of the internal thread 61 and the external thread 33. The connector 6 is constrained to the cleaning brush body 1 by the constraint formed between the convex strip 13 and the convex ring 62. When the convex strip 13 and the convex ring 62 abut, the continued movement of the connector 6 is restricted, preventing the connector 6 from detaching from the cleaning brush body 1 and thus rendering its function of connecting the handle 3 and the cleaning brush body 1 ineffective. At the same time, the handle 3 and the cleaning brush body 1 are connected by the threaded connection between the connector 6 and the connecting part 32. When connecting the handle 3 and the cleaning brush body 1, after connecting the first terminal 31 and the second terminal 11, the connection between the handle 3 and the cleaning brush body 1 is maintained by the engagement of the internal thread 61 and the external thread 33. When detaching the handle 3 and the cleaning brush body 1, the engagement of the internal thread 61 and the external thread 33 is first released, the connector 6 is disassembled from the connecting part 32, and the handle 3 and the cleaning brush body 1 are detached by applying a reverse force to the handle 3 and the cleaning brush body 1 to release the engagement of the first terminal 31 and the second terminal 11.
[0037] In addition, a circuit board electrically connected to the battery 4 is installed inside the handle 3. The circuit board has a button 8 for controlling the motor 5 to turn on and off. The button 8 is exposed on the outer surface of the handle 3. Positioning the button 8 on the handle 3 facilitates turning the electric cleaning brush on and off while holding the handle 3, and allows for one-handed operation. A hanging rope 7 is provided at the end of the handle 3 away from the connecting part 32, allowing the electric cleaning brush to be suspended and stored when not in use.
