Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a faucet with filtering and purifying functions. Background Art

[0002] A faucet is a device used to control the flow of water, usually installed at the end of a water pipe. It includes a handle or knob that controls the opening and closing of the water flow by turning or pushing. There are many types of faucets, including ordinary kitchen and bathroom faucets, as well as water-saving and automatic sensor faucets.

[0003] A Chinese patent discloses a faucet with filtering and purifying functions (publication number: CN216639132U). The device can effectively filter particulate impurities mixed in the water through the setting of the filter screen, and can absorb harmful substances such as discoloration, odor ozone, bacteria and bleaching powder in the water through the setting of the activated carbon filter element to improve the taste of the water quality. The setting of PP cotton can roughly filter the raw water and remove impurities above five microns such as mud, rust, and red worms. The setting of the softening resin filter element can effectively soften hard water and prevent the formation of scale, and absorb calcium and magnesium ions that form scale, so that the body can effectively have water filtering and purification functions, and at the same time solve the problem that common faucets on the market generally do not have filtering and purification functions;

[0004] The above device also has the following defects: when an activated carbon filter element and a softening resin filter element are contaminated or saturated with adsorption, it is not easy to remove and replace the contaminated purification component, and the entire purification box may need to be disassembled, which has a high cost of use. Therefore, a faucet with filtering and purification function is proposed to solve the above problem. Utility Model Content

Figure 2-Figure 4 As shown, the positioning rail 211 limits the orientation of the mounting ring 216 inside the inner filter sleeve 210 through the positioning block 217, ensuring that the groove 218 can dock with the ball 214;

[0031] A slider 212 is slidably connected to the lower end of the inner wall of the inner filter sleeve 210 and near the bottom mounting ring 216. One side of the slider 212 passes through the inner filter sleeve 210 and is fixedly connected to an extrusion piece 213. The extrusion piece 213 is located on a side near the mounting ring 216 and is set as an inclined surface. Figure 3 As shown, when the slider 212 descends, the extrusion member 213 separates from the ball 214;

[0032] The bottom of the slider 212 is fixedly connected with a spring 215, and the other end of the spring 215 is fixedly connected with the inner wall of the inner filter sleeve 210. The extrusion piece 213 is located on one side of the inclined surface and is movably contacted with a ball 214. The ball 214 is movably connected with the inner part of the inner filter sleeve 210, and one end of the ball 214 passes through the inner filter sleeve 210 and is engaged with the inner side of the slot 218. Figure 3 As shown, when the extrusion member 213 abuts against the ball 214, the ball 214 can support the inner side of the column slot 218 and bear the weight of the mounting ring 216;

[0033] The filtering mechanism 2 also includes an upper protective sleeve 201, a water inlet 202 is fixedly installed on the top of the upper protective sleeve 201, the inner top of the water inlet 202 is threadedly connected to the faucet body 1, and the lower end of the outer wall of the upper protective sleeve 201 is fixedly connected to a connecting portion 203, and a support groove 204 is provided on one side of the outer wall of the connecting portion 203. The support groove 204 is in an inverted L-shape as a whole, and the length direction of the lower end of the support groove 204 is consistent with the length direction of the upper protective sleeve 201 as a whole. The inner side of the upper protective sleeve 201 is movably sleeved with the inner filter sleeve 210, and one end of the side wall of the inner filter sleeve 210 is fixedly connected with a push piece, and the inner filter sleeve 210 is located at the push piece and passes through the inner side of the support groove 204, such as Figure 1-Figure 2 As shown, the push piece is pushed toward the rear of the filter mechanism 2 and then pushed downward to drive the inner filter sleeve 210 to separate from the upper protective sleeve 201;

[0034] A mounting block 205 is fixedly installed on the outer wall of the upper protective sleeve 201 and on one side close to the upper end of the supporting groove 204, and an insertion shaft 206 is slidably connected to the inner wall of the mounting block 205. A spring 207 is fixedly connected to the outer side of the mounting ring 216, and the other end of the spring 207 is fixedly connected to the mounting block 205. One end of the insertion shaft 206 passes through the mounting block 205 and is connected to the push plate of the inner filter sleeve 210. Figure 6 As shown, the insertion shaft 206 locks the push piece on the side of the inner filter sleeve 210;

[0035] The outer wall of the connecting portion 203 is threadedly connected with a lower protective sleeve 208, the inner middle part of the lower protective sleeve 208 is movably connected to the bottom surface of the inner filter sleeve 210, and the middle of the bottom of the lower protective sleeve 208 is rotatably connected with a water outlet pipe 209. Figure 1 , Figure 5 As shown, the direction of water flow can be adjusted by rotating the water outlet pipe 209.

[0036] The inner filter sleeve 210 has openings at the top and bottom. The top opening of the inner filter sleeve 210 is connected to the inside of the water inlet 202 , and the bottom opening of the inner filter sleeve 210 is connected to the inside of the water outlet pipe 209 .

[0037] The working principle of this utility model:

[0038] When the device is in use, the water inlet 202 in the filter mechanism 2 is screwed onto the outside of the output end of the faucet body 1 through a thread, and the water flows through the purification layers 220 inside the inner filter sleeve 210 and then outputs from the water outlet pipe 209;

[0039] Secondly, when the purification layer 220 needs to be replaced, the filter mechanism 2 is first removed, and the lower protective sleeve 208 is rotated to separate it from the upper protective sleeve 201, and then the sliders 212 on both sides are pushed down, and the extrusion piece 213 is separated from the ball 214. Then, the ball 214 cannot bear the weight of all the mounting rings 216, and the ball 214 is retracted into the inner filter sleeve 210. The mounting ring 216 falls down under the action of gravity and is separated from the inner filter sleeve 210;

[0040] In addition, when it is necessary to remove the scale on the inner wall of the inner filter sleeve 210, the positioning block 217 can be pulled to separate it from the push plate that allows the inner filter sleeve 210 to pass through the support groove 204. The inner filter sleeve 210 can then be controlled by the push plate to rotate a certain angle as a whole in the upper protective sleeve 201, and then the upper protective sleeve 201 can be pushed out along the length direction of the support groove 204.

[0041] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
