[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0050] The present invention relates to a cleaning tool, including a cleaning head 10, a locking part 20, and a handheld part 30. The cleaning head 10 includes a connecting part 11. The locking part 20 is provided with a connecting and cooperating part 21. The connecting part 11 cooperates with the connecting and cooperating part 21 to connect the locking part 20 to the cleaning head 10;

[0051] An installation cavity 31 is provided at the end of the handheld part 30. When the locking part 20 connected to the cleaning head 10 is inserted into the installation cavity 31, the handheld part 30 applies pressure to the locking part 20 to limit the locking part 20 from coming out, and the connecting and cooperating part 21 limits the connecting part 11, thereby restricting the cleaning head 10 from coming out of the locking part 20.

[0052] In this example, the preferred cleaning tool is a toilet brush. The cleaning head 10 is used to directly contact the surface to be cleaned, specifically, to clean by rubbing against the inner wall of the toilet. The cleaning surface of the cleaning head 10 in contact with the inner wall of the toilet has a cleaning brush or other wiping materials such as a cleaning sponge 14. A connecting portion 11 is provided on the cleaning head 10, which is adapted to be connected to the handheld portion 30 to extend the distance between the hand and the cleaning head 10, so as to prevent the user's hands from getting dirty when cleaning the toilet. The cleaning tool further includes a handheld portion 30, and the handheld portion 30 is used to form a handle for the user to hold and drive for cleaning.

[0053] In this example, the preferred cleaning tool further includes a locking portion 20. The cleaning head 10 is connected to the handheld portion 30 through the locking portion 20, so that the cleaning head 10 is reliably installed at the end of the handheld portion 30, preventing the cleaning head 10 from detaching from the handheld portion 30 during use and affecting the user experience. On the one hand, the locking portion 20 is connected to the cleaning head 10, and on the other hand, it is connected to the handheld portion 30. The locking portion 20 includes a connecting and mating portion 21 for mating and connecting with the connecting portion 11 on the cleaning head 10, thereby installing the locking portion 20 on the cleaning head 10. And an installation cavity 31 is provided at the end of the handheld portion 30, and the installation cavity 31 is connected to the locking portion 20. Specifically, first install the locking portion 20 on the cleaning head 10, and then insert the locking portion 20 into the installation cavity 31, thereby connecting the handheld portion 30 and the cleaning head 10. In this example, preferably, the locking portion 20 is in interference fit with the installation cavity 31, that is, the width of the locking portion 20 is slightly larger than the width of the installation cavity 31, so that when the locking portion 20 is inserted into the installation cavity 31, the locking portion 20 forms a tight fit with the handheld portion 30 to limit the locking portion 20 from detaching from the installation cavity 31. It can be understood that the locking portion 20 and the installation cavity 31 can also be fixed by gluing, buckling or other limiting members.

[0054] Among them, when the locking portion 20 is installed on the cleaning head 10 and the locking portion 20 is not under pressure, the locking portion 20 and the cleaning head 10 form a pre-installation state. In this state, the locking portion 20 can be easily removed from the cleaning head 10. In the pre-installation state, it is convenient for the handheld portion 30 to be pre-positioned when installing with the locking portion 20 and the cleaning head 10, so as to improve the assembly efficiency of the cleaning tool. When inserting the locking portion 20 into the installation cavity 31 of the handheld portion 30 for installation, the handheld portion 30 can lock the cleaning head 10 by applying pressure to the locking portion 20, that is, only need to connect the locking portion 20 with the cleaning head 10 and then insert the locking portion 20 into the handheld portion 30 to complete the installation of the cleaning head 10 and the handheld portion 30. The installation method is simpler and more efficient, and the installation is more reliable. And because the handheld portion 30 is not the two-piece type in the prior art, the stability of the handheld portion 30 is better, and further the locking stability between the locking portion 20 and the cleaning head 10 is better, the installation of the cleaning head 10 is more firm, not easy to loosen and detach, and the user experience is better.

[0055] Wherein, when the locking part 20 connected to the cleaning head 10 is inserted into the installation cavity 31, the inner wall of the installation cavity 31 presses on the locking part 20, so that the locking part 20 contracts or deforms in the direction towards the connecting part 11, and further enables the connecting and mating part 21 and the connecting part 11 to be in limit fit, so as to prevent the cleaning head 10 from disengaging from the locking part 20. In this example, preferably, the locking part 20 is made of a material with certain elasticity at least at the connecting and mating part 21, such as plastic, rubber, soft rubber or soft metal and other materials.

[0056] In an alternative embodiment, the connecting and mating part 21 has a first state and a second state. When the connecting and mating part 21 is in the first state, the connecting and mating part 21 limits the connecting part 11, that is, the connecting part 11 cannot disengage from the connecting and mating part 21. When the connecting and mating part 21 is in the second state, the connecting and mating part 21 is disengaged from the connecting part 11, that is, the connecting part 11 can be freely disengaged from and installed in the connecting and mating part 21. Specifically, the connecting and mating part 21 has two states, and the two states correspond to different mating methods with the connecting part 11. Therefore, only by adjusting the state change of the connecting and mating part 21 can the locking of the cleaning head 10 be realized, and the installation method is simpler.

[0057] In an alternative embodiment, the connecting and mating part 21 includes at least a first connecting arm 211 and a second connecting arm 212. In the first state, the first connecting arm 211 and the second connecting arm 212 approach each other to limit the connecting part 11 therebetween; in the second state, the first connecting arm 211 and the second connecting arm 212 move away from each other to cancel the limit on the connecting part 11. Specifically, multiple connecting arms are provided to realize the limit on and cancellation of the limit on the connecting part 11 by approaching and moving away from each other, thereby controlling the installation of the cleaning head 10 and the locking part 20. The installation method is simple and reliable. Preferably, there are 2 connecting arms. On the one hand, it is convenient for processing, and on the other hand, the width of the connecting arm can be set wider, improving the strength of the connecting arm and reducing the probability of damage to the locking part 20. Preferably, at least two strip-shaped through grooves extending in the direction towards the cleaning head 10 are provided on the side wall of the locking part 20, and the side parts between adjacent through grooves form connecting arms.

[0058] In an alternative embodiment, the handheld portion 30 applies pressure to the connection and mating portion 21 to cause the connection and mating portion 21 to transition from the second state to the first state. Specifically, in this example, preferably, the locking portion 20 is inserted into the installation cavity 31 of the handheld portion 30, and the inner sidewall of the installation cavity 31 applies pressure to the connection and mating portion 21 of the locking portion 20. Preferably, when the locking portion 20 is inserted into the installation cavity 31, the connection and mating portion 21 has a tendency to expand outward and will abut against the inner wall of the installation cavity 31. Since the space of the installation cavity 31 is fixed, it can be understood that the inner sidewall of the installation cavity 31 restricts the expansion tendency of the connection and mating portion 21, that is, the inner sidewall of the installation cavity 31 applies pressure to the connection and mating portion 21. The locking method of the locking portion 20 is simpler and more secure.

[0059] In an alternative embodiment, when the connection and mating portion 21 is not under pressure, the connection and mating portion 21 can be maintained in the second state by its own elastic force or external force drive. Specifically, in this example, the state where the connection and mating portion 21 is not under pressure is the state where the locking portion 20 is not inserted into the installation cavity 31, that is, the state when the locking portion 20 is not assembled or the state when the locking portion 20 is not in use. The locking portion 20 is in the second state, that is, the connecting portion 11 and the locking portion 20 can be freely separated, and at the same time, it is also convenient to install and position the connecting portion 11 and the locking portion 20, thereby facilitating subsequent locking operations. In the second state, the connection and mating portion 21 has a tendency to expand, that is, the connecting arms have a tendency to move away from each other. Preferably, the expansion tendency of the connection and mating portion 21 can be determined by its own material. For example, when the connecting arms are made of an elastic material, they are initially processed to have an expansion tendency. It can be understood that setting an elastic member between the connecting arms can also achieve the expansion tendency of the connecting arms, and at the same time, it is also convenient for the connecting arms to approach each other. The elastic member can be made of materials such as springs or soft rubber.

[0060] In an alternative embodiment, the middle portion of the locking portion 20 has a first chamber 22 adapted to accommodate the connecting portion 11. Specifically, in this example, preferably, the volume of the first chamber 22 can be adjusted. For example, an arc-shaped semi-circular plate is provided on the inner side of the connecting arm, and multiple semi-circular plates can be spliced into the first chamber 22. The volume of the first chamber 22 is adjusted by the mutual separation and approach of multiple connecting arms. Of course, the shape of the semi-circular plate can be determined by the shape of the connecting portion 11. The first chamber 22 with adjustable volume is convenient for locking or unlocking the connecting portion 11. When the volume is reduced, the connecting portion 11 accommodated in the first chamber 22 can be tightly wrapped to prevent the connecting portion 11 from detaching; when the volume is increased, it is convenient for the connecting portion 11 to be inserted into the first chamber 22 for installation and positioning.

[0061] In an alternative embodiment, a second limiting portion 23 is provided in the first chamber 22 and is adapted to limit the connecting portion 11 through the second limiting portion 23 after the connecting portion 11 is engaged with the connecting and mating portion 21. Specifically, providing the second limiting portion 23 in the first chamber 22 can limit the connecting portion 11, prevent the connecting portion 11 from disengaging from the first chamber 22, and make the connection more firm and reliable.

[0062] In an alternative embodiment, the second limiting portion 23 is configured to protrude along an end of the chamber wall of the first chamber 22 close to the cleaning head 10. Specifically, preferably, the second limiting portion 23 can be a protruding block. Correspondingly, a groove cooperating with the protruding block is provided in the connecting portion 11. When the protruding block is engaged with the groove, the second limiting portion 23 and the connecting portion 11 are limited. It can be understood that the shapes of the engaging structures of the two can be interchanged to achieve the limiting function. The protruding second limiting portion 23 has a simple structure, is convenient for processing and forming as well as assembly, and is convenient for clamping the connecting portion 11 to prevent the connecting portion 11 from disengaging.

[0063] In an alternative embodiment, a first limiting portion 24 is provided on a side of the locking portion 20 cooperating with the hand-held portion 30, and a first limiting and cooperating portion 32 is provided on the inner wall of the installation cavity 31. The first limiting portion 24 cooperates with the first limiting and cooperating portion 32 to limit the locking portion 20 from disengaging from the installation cavity 31. Specifically, by providing a limiting structure in the locking portion 20 and the installation cavity 31, it can effectively prevent the locking portion 20 from falling off from the installation cavity 31 during use, thereby causing the cleaning head 10 to fall off.

[0064] In an alternative embodiment, the first limiting portion 24 is configured as a protruding structure provided on the connecting and mating portion 21, and the first limiting and cooperating portion 32 is configured as a groove structure provided on the inner wall of the installation cavity 31. Specifically, the cooperation of the protrusion and the groove is simple to process and is also convenient for assembly. Preferably, a plurality of annular protruding structures are provided on the outer side wall of the locking portion 20 corresponding to the connecting and mating portion 21, and correspondingly, a plurality of groove structures cooperating with the protruding structures are provided on the inner side wall of the installation cavity 31, so that when the locking portion 20 is engaged with the installation cavity 31, the installation reliability of the locking portion 20 can be increased. It can be understood that a plurality of protruding structures can be provided and are annularly distributed on the outer side wall of the locking portion 20.

[0065] It can be understood that the first limiting portion 24 is configured as a groove structure provided on the outer side wall of the locking portion 20 corresponding to the connecting and mating portion 21, and the first limiting and cooperating portion 32 is configured as a protruding structure provided on the inner side wall of the installation cavity 31. The protruding structure cooperates with the groove structure to limit the locking portion 20 in the installation cavity 31.

[0066] In an alternative embodiment, the cleaning head 10 includes a cleaning base 13 and a wiper 14. A connecting portion 11 is provided on one side of the cleaning base 13, and the wiper 14 is mounted on at least the other side. Specifically, the cleaning base 13 is used to mount the wiper 14 and to provide the connecting portion 11 for connecting with the handheld portion 30. The wiper 14 is used to perform friction cleaning on the surface to be cleaned. In this example, preferably, the cleaning base 13 includes an upper substrate 131 and a lower substrate 132, which are snap-connected. This not only facilitates assembly but also enables the cleaning base 13 to have a certain thickness. When the wiper 14 is mounted on the cleaning base 13, not only the bottom of the cleaning base 13 can be used for cleaning, but also the side portion of the cleaning base 13 can be used for cleaning, thus meeting different cleaning needs of users and providing a better experience. In this example, preferably, the wiper 14 is sleeved on the cleaning base 13, that is, the wiper 14 completely covers the lower substrate 132 and partially covers the upper substrate 131. A connecting portion 11 is provided in the middle of the upper substrate 131, so that both the bottom and the side portion of the cleaning base 13 can be covered by the wiper 14. The wiper 14 is at least provided on one side of the cleaning base 13 opposite to the connecting portion 11, which conforms to the operation habits of users.

[0067] In an alternative embodiment, the connecting and mating portion 21 is provided with a second limiting portion 23, and the connecting portion 11 is provided with a second limiting and mating portion 12, which is adapted to perform mating and limiting through the second limiting portion 23 and the second limiting and mating portion 12 after the connecting portion 11 is mated with the connecting and mating portion 21. Specifically, a limiting and mating portion is provided on the connecting portion 11, which can cooperate with the second limiting portion 23 on the locking portion 20, so as to better position and limit when the locking portion 20 is mated and connected with the connecting portion 11. In this example, preferably, the second limiting and mating portion 12 is provided between the connecting portion 11 and the cleaning base 13.

[0068] In an alternative embodiment, the connecting portion 11 includes a connecting head 111. The connecting head 111 extends to the cleaning base 13 through the second limiting and mating portion 12 whose width is smaller than that of the connecting head 111. When the connecting head 111 is received in the connecting and mating portion 21 and the second limiting portion 23 is snap-fitted with the second limiting and mating portion 12, the connecting portion 11 is in limiting and mating with the connecting and mating portion 21. Specifically, a relatively thin second limiting and mating portion 12 is formed between the connecting head 111 and the cleaning base 13, which facilitates the second limiting portion 23 to be snap-fitted at the second limiting and mating portion 12, avoiding the separation of the second limiting portion 23, and making the cooperation between the locking portion 20 and the cleaning head 10 more firm. Since a first chamber 22 is provided in the locking portion 20 and a protruding second limiting portion 23 is provided at one end of the first chamber 22 close to the cleaning head 10, when the connecting head 111 is received in the first chamber 22, the protruding second limiting portion 23 can be snap-fitted at the relatively thin second limiting and mating portion 12, effectively preventing the connecting head 111 from separating from the first chamber 22 and making the installation of the locking portion 20 and the cleaning head 10 more reliable.

[0069] In an alternative embodiment, the connecting head 111 has a spherical structure, and the connecting and mating portion 21 is correspondingly provided with a spherical first chamber 22 for receiving the connecting head 111. Specifically, in this example, the top of the connecting head 111 is preferably designed with glue stealing. On the one hand, it saves costs, and on the other hand, it ensures the overall wall thickness of the connecting head 111, facilitating mold forming. The spherical connecting head 111 enables the cleaning head 10 to rotate in all directions to adapt to the user's needs for cleaning stains in different corners, providing a better user experience.

[0070] In an alternative embodiment, the cleaning head 10 includes a cleaning base 13. There is a spacing between the handheld portion 30 and the cleaning base 13, which is suitable for reserving a space for the cleaning head 10 to rotate. Specifically, the spacing facilitates the rotation of the cleaning head 10 and avoids interference between the cleaning base 13 and the handheld portion 30, thus affecting the user experience. In this example, the upper substrate 131 preferably tends to contract in the direction towards the connecting portion 11, so that the thickness of the cleaning base 13 gradually decreases from its center towards the edge. When the cleaning head 10 rotates by a certain angle relative to the handheld portion 30, the cleaning base 13 will form an avoidance with the handheld portion 30, or there is a certain height between the connecting head 111 and the cleaning base 13. When the handheld portion 30 is connected to the connecting head 111, there must be a certain spacing between the handheld portion 30 and the cleaning base 13.

[0071] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
