Description

Technical Field

[0001] The utility model relates to the technical field of rock drill equipment, in particular to a water filter device for a water needle. Background Art

[0002] At present, the rock drill uses water to spray water to cool down the impact position. When the rock drill is connected to the water supply pipe, due to the excessive pressure, it is only connected by thread, which is prone to water seepage and leakage, affecting the normal use of the rock drill.

[0003] After searching, the application number of the Chinese patent document is CN202320728936.0. The utility model provides a self-cooling rock drill, including a rock drill body, a handle and a head. The handle is installed at one end of the rock drill body, and the head is installed at the end of the rock drill body opposite to the handle. The chiseling end of the head is installed with a drill clamp, and a trachea elbow is connected to one side of the rock drill body, and a water pipe elbow is arranged on one side of the trachea elbow; a water needle sleeve is installed on the central axis of the rock drill body, and the end of the water needle sleeve close to the drill tail is connected with a water needle; the utility model is achieved by threading the docking flange with the water pipe elbow, and connecting the first sealing ring to the water pipe elbow and the docking flange, and then connecting the other end of the docking flange with the water supply pipe, and then connecting the second sealing ring between the docking flange and the water supply pipe, and then using the sealing gasket to seal the connection between the water pipe elbow, the docking flange and the water supply pipe, so as to ensure that the rock drill body will not seep or leak when using water.

When the water quality of the water sprayed by the water needle is poor, impurities are easily attached to the water needle water supply pipes. After long-term use, it is easy to clog the water needle nozzle and water supply pipes and other parts, thereby making the water needle structure unusable. Therefore, we need to propose a water filter device for water needles to solve the above problems. Utility Model Content

Two sets of filter structures 220 are arranged in the filter cartridge 201. The filter structure 220 includes a filter frame 221. A filter layer 223 is embedded on the filter frame 221. A second joint ring 213 is integrally formed on the filter cover 211. The water delivery hose 120 is fixed to the second joint ring 213 through a second interface hose clamp 214 to prevent a gap between the water delivery hose 120 and the second joint ring 213, which causes water leakage between the water delivery hose 120 and the second joint ring 213.

[0022] During use, water flows through the water supply hose 120 and is introduced into the filter cartridge 201 which is closed by the filter cover 211. The extracted water flow is finely filtered by two sets of filter structures 220, and the filtered water flow is sprayed out through the water needle nozzle assembly 100. Impurities in the water flow will be filtered out and retained in the filter layer 223 or the filter cartridge 201.

When the filter structure 220 needs to be replaced, the filter cover 211 can be opened to take out the filter structure 220 for replacement.

[0024] A rubber sealing ring 222 is fixed on the outer wall of the filter frame 221, and the outer wall of the rubber sealing ring 222 contacts the inner wall of the filter cartridge 201 to prevent water from flowing out through the gap between the filter frame 221 and the filter cartridge 201, thereby causing the water to flow out of the filter cartridge 201 without being filtered. Three groups of first filter sleeves 224 are embedded in the filter layer 223.

[0025] A filter box 231 is arranged between the two groups of filter frames 221. The two sides of the filter box 231 are provided with filter screens.
