Description

Technical Field

[0001] The utility model relates to a water-passing brush. Background Art

[0002] A water-through brush is a brush with water flowing inside. Its structure usually includes a water-through brush head and a brush rod. The length of the brush rod is usually not adjustable, that is, the brush rod is not a telescopic tube. Because water needs to flow inside the brush rod, if the brush rod is designed as a telescopic tube, it is necessary to set multiple gear adjustment holes on the brush rod to cooperate with the telescopic button. However, the existence of the gear adjustment holes will cause the brush rod to leak. Therefore, how to develop a water-through brush with a telescopic tube is the research direction that the staff in this field want to study. Utility Model Content

[0012] In order to more intuitively and completely understand the technical solution of the utility model, the following non-limiting feature description is now provided in conjunction with the accompanying drawings of the utility model:

[0013] like Figure 1 — Figure 3 As shown, a water-passing brush comprises a brush head 1, and a telescopic tube 2. The telescopic tube 2 comprises a first water-passing tube 21 connected to the brush head 1, a second water-passing tube 22 which is sleeved outside the first water-passing tube 21 and slidably matched with the first water-passing tube 21 up and down, a water inlet joint 3 is fixed to the upper end of the second water-passing tube 22, the water inlet joint 3, the second water-passing tube 22, the first water-passing tube 21, and the brush head 1 are connected from top to bottom, and a partition 211 extending up and down is provided in the first water-passing tube 21, and a water-passing tube 21 is provided through the partition 21. The first water pipe 21 is divided into a cavity 212 and a water cavity 213 which are not connected to each other. The water cavity 213 is connected to the second water pipe 22 and the brush head 1. A fixing seat 4 is fixed to the lower end of the second water pipe 22. An unlocking mechanism is installed on the fixing seat 4. The unlocking mechanism includes a locking rod 5. A plurality of gear adjustment holes 214 distributed up and down are provided on the outer wall of the first water pipe 21. The gear adjustment holes 214 are connected to the cavity 212. The locking rod 5 is inserted into one of the gear adjustment holes 214.

[0014] like Figure 3 As shown, a sleeve pipe 6 is clamped on the upper end of the first water pipe 21, and the sleeve pipe 6 extends into the second water pipe 22. A sealing ring is installed between the outer wall of the sleeve pipe 6 and the inner wall of the second water pipe 22 to prevent water leakage.

[0015] like Figure 3 As shown, the unlocking mechanism also includes a button 7 and a spring 8. The middle part of the button 7 is hinged to the outside of the fixing seat 4. The spring 8 is stuck between the inner side of the upper end of the button 7 and the outer side of the fixing seat 4. The locking rod 5 is fixedly connected to the lower end of the button 7. After pressing the button 7, the spring 8 is compressed, and the locking rod 5 moves out of the gear adjustment hole 214. The second water pipe 22 can be moved, and the length of the first water pipe 21 inserted into the second water pipe 22 can be adjusted. After releasing the hand, the second water pipe 22 can be finely adjusted up and down. The locking rod 5 is stuck in the gear adjustment hole 214 by the elastic force of the spring 8, and the length adjustment is completed.

[0016] In the water-passing brush provided by the utility model, the partition plate 211 can separate the water, so the gear adjustment hole 214 will not leak water, so the water-passing brush with the telescopic tube 2 is more flexible and convenient to use.
