DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 1 and Figure 2 , an embodiment of the utility model: a combined brush includes a brush head 1, a connecting column 4 is fixedly connected to the top of the brush head 1, a handle 2 is arranged on the outer wall of the connecting column 4, a card slot 3 is opened inside the handle 2, a limiting plate 10 is slidably connected inside the handle 2, a release rod 11 is fixedly connected to one side of the limiting plate 10, a push block 12 is fixedly connected to the other side of the limiting plate 10, a reset component is arranged on the outer wall of the push block 12, a limiting plate 5 is slidably connected inside the connecting column 4, a card block 6 is rotatably connected inside the connecting column 4, the outer wall of the card block 6 is embedded in the card slot 3, and the card block A support rod 7 is rotatably connected inside the one-6, one end of the support rod 7 is rotatably connected inside the limit plate 5, a telescopic rod 9 is arranged inside the connection column 4, the outer wall of the telescopic rod 9 is sleeved with a first spring 8, one end of the telescopic rod 9 and the first spring 8 are fixedly connected to one side of the limit plate 5, and the other end of the telescopic rod 9 and the first spring 8 are fixedly connected inside the connection column 4, and the reset assembly includes a second spring 13, the second spring 13 is sleeved inside the outer wall of the push block 12, one end of the second spring 13 is fixedly connected to the other side of the limit plate 10, and the other end of the second spring 13 is fixedly connected to the inside of the handle 2;
[0031] Specifically, when installing the brush head 1, the process is simple and direct. You only need to insert the brush head 1 into the interior of the handle 2 through the connecting column 4. Once the brush head 1 is inserted into place, the card block 6 in the connecting column 4 will naturally fit into the card slot 3, thereby achieving a stable locking of the brush head 1 and the handle 2. This fitting process can be achieved because the card block 6 is connected to the interior of the connecting column 4 through the support rod 7 and the limit plate 5, forming an effective limit mechanism. At the same time, the tension support of the first spring 8 also plays a key role, which ensures that the card block 6 is not easy to slide out when it is embedded in the card slot 3, thereby enhancing the stability of the connection between the brush head 1 and the handle 2. However, when the brush head 1 needs to be removed or replaced, the process is also simple and convenient. You only need to pinch the release rods 11 on both sides and push them gently. The action of the release rod 11 will drive the push block 12 to extend into the interior of the card slot 3, thereby pushing the card block 6 into the interior of the connecting column 4. Once the card block 6 is released, you can easily separate the brush head 1 from the handle 2. After the brush head 1 is replaced, the release rod 11 is released, and it will automatically reset under the tension of the second spring 13, and push the limit plate 2 10 to drive the push block 12 to reset, so as to prepare for the next use.
[0032] Reference Figure 3A cavity 15 is provided inside the brush head 1, a fixed column 14 is fixedly connected to the top of the brush head 1, a limiting plate 3 17 is slidably connected inside the fixed column 14, a support rod 2 16 is fixedly connected inside the limiting plate 3 17, a roller 18 is rotatably connected to the outer wall of the support rod 2 16, the outer wall of the support rod 2 16 is slidably connected inside the brush head 1, a limiting block 19 is slidably connected inside the fixed column 14, a release rod 2 21 is fixedly connected to one side of the limiting block 19, a clamping block 20 is fixedly connected to the other side of the limiting block 19, a third spring 22 is sleeved on the outer wall of the release rod 21, one end of the third spring 22 is fixedly connected to one side of the limiting block 19, and the other end of the third spring 22 is fixedly connected to the inside of the fixed column 14;
[0033] Specifically, when the roller 18 in the brush head 1 needs to be used, the operation process is very simple. First, just press the support rod 2 16, which is an important part of the brush head 1 and is responsible for supporting and fixing the roller 18. Through the action of the support rod 2 16, the roller 18 will smoothly extend out of the brush head 1. Next, to ensure that the roller 18 will not accidentally retract during the process of extending the brush head 1, the clamping block 2 20 is needed. It is closely matched with the limiting plate 3 17 to clamp and limit the roller 18, ensuring that the roller 18 is stable and reliable when extending the brush head 1 and will not retract into the inside of the brush head 1. When the roller 18 is not needed, the operation is equally simple. Just pull out the release rod 2 21, which is the key component for controlling the clamping block 2 20. Driven by the release rod 2 21, the clamping block 2 20 will retract into the inside of the fixed column 14 and separate from the limiting plate 3 17. At this time, the support rod 2 16 can slide freely, and the roller 18 will also retract into the inside of the brush head 1.
[0034] Working principle: When using the combined brush, first install the brush head 1, just directly insert the brush head 1 into the handle 2 through the connecting column 4, and lock it by fitting the block 6 in the connecting column 4 into the card slot 3. The block 6 is connected to the connecting column 4 through the support rod 7 and the limit plate 5 for limiting. At the same time, the tension support of the first spring 8 makes it difficult for the block 6 to slide out when it is fitted in the card slot 3. When the brush head 1 needs to be disassembled and replaced, just pinch the release rods 11 on both sides, and drive the push block 12 to extend into the card slot 3 through the release rods 11 to push the block 6 into the connecting column 4. Then, separate the brush head 1 from the handle 2, and release the release rod 11. Under the tension of the second spring 13, the limit plate 2 10 will be pushed to drive the push block 12 to reset. Then, when the roller 18 in the brush head 1 needs to be used, only the support rod 2 16 needs to be pressed, and the roller 18 is driven to extend out of the brush head 1 through the support rod 2 16. Then, the limit plate 3 17 is clamped and limited by the clamping block 20, so that when the roller 18 extends out of the brush head 1, it will not be retracted into the brush head 1. When the roller 18 is not needed, only the release rod 21 needs to be pulled out, and the clamping block 20 is driven to retract into the fixed column 14 through the release rod 21, so that the clamping block 20 is separated from the limit plate 3 17, so that the support rod 2 16 can slide, and then the roller 18 is retracted into the brush head 1.
[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
