Technical Field

[0001] This utility model relates to the field of angle valves, specifically to an easy-to-clean angle valve. Background Technology

[0002] Angle valves are common valves used in daily life to bring pipes out of the wall and connect them to water-using equipment. The most traditional angle valves use moving and stationary ceramic discs to open and close, making it difficult to install an internal filtration structure. Existing filter angle valves on the market require disassembly of the internal core assembly to clean the sediment and scale that are filtered out.

[0003] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Summary of the Invention

[0004] The main purpose of this utility model is to provide an easy-to-clean angle valve, which solves the problem mentioned in the background art that the inner core needs to be removed for cleaning, making cleaning more convenient.

[0005] To achieve the above objectives, the solution of this utility model is: An easy-to-clean angle valve includes a valve housing and an inner core installed within the valve housing. A filter screen is connected to the inner core. A guide rod is slidably connected within the inner core, and a discharge channel is formed within the guide rod. The side of the guide rod has a lateral communication hole connecting to the discharge channel. A water-stop ring is provided at the end of the guide rod located within the filter screen. The diameter of the water-stop ring is smaller than the inner diameter of the filter screen. The guide rod has a water-stop position and a slag-discharge position. When the guide rod is in the water-stop position, the water-stop ring blocks the inner cavity of the filter screen from the lateral communication hole. When the guide rod is in the slag-discharge position, the water-stop ring separates from the inner core and connects the inner cavity of the filter screen to the lateral communication hole.

[0006] Furthermore, the lateral connecting holes have several distributed along the circumference of the guide rod.

[0007] Furthermore, a cap is provided at the end of the outlet rod away from the waterstop ring, and a side channel is formed on the side of the cap, which is connected to the discharge channel of the outlet rod.

[0008] Furthermore, the angle valve housing also has a water pipe that abuts against it, and the filter screen abuts against the water pipe.

[0009] Furthermore, the guide rod also has an impact water flow net located inside the filter screen, the side wall of the impact water flow net is formed with a plurality of jet holes, one end of the impact water flow net is also formed with a support cylinder, the side of the support cylinder is formed with a side water outlet; the support cylinder extends into the inner cavity of the abutting water pipe.

[0010] Furthermore, a sealing gasket is provided at the end of the impact water flow net on the outer periphery of the support cylinder; when the guide rod is in the slag discharge position, the sealing gasket abuts and seals with the end of the abutting water pipe.

[0011] Furthermore, a first bearing is provided between the impact water flow net and the discharge rod, and a second bearing is provided at the end of the impact water flow net on the outer periphery of the support cylinder; when the discharge rod is in the slag discharge position, the second bearing abuts against the end of the abutting water pipe; a swirl blade is formed inside the support cylinder; under the drive of the water flow, the impact water flow net rotates relative to the filter screen.

[0012] Furthermore, a water-stop pad is provided on the water inlet pipe located outside the water inlet pipe of the angle valve housing; the water-stop pad can open or block the water inlet pipe as the water inlet pipe moves axially.

[0013] Furthermore, the abutting water pipe located outside the water inlet pipe of the angle valve housing abuts against the inner core of the stop valve.

[0014] Furthermore, the inner core is threadedly connected to the angle valve housing and moves axially as the inner core and the angle valve housing rotate.

[0015] With the above structure, the easy-to-clean angle valve of this utility model has at least the following beneficial effects: 1. The inner core is installed inside the angle valve housing to control the flow of water through and off the angle valve. With use, sediment and scale accumulate on the inner wall of the filter screen. When cleaning is required, pressing the discharge rod switches it from the water-stop position to the slag discharge position, connecting the inner cavity of the filter screen with the side communication hole. The sediment and scale are then discharged through the discharge channel of the discharge rod with the water flow. After the discharge rod returns to the water-stop position, it remains in the water-stop position under water pressure.

[0016] Second, the increased pressure area of ​​the cap on the discharge rod makes the pressing operation more convenient. Simultaneously, the side channel on the cap directs the water flow from the discharge channel to the side, allowing the user to easily collect it using a container.

[0017] Third, by setting up an impact water flow net, after pressing the guide rod, the water flow is concentrated into the impact water flow net and discharged through the jet holes. The jet washes the inner wall of the filter screen, allowing scale and silt to be fully discharged. The support cylinder also supports the impact water flow net, making its installation more stable. After the guide rod returns to the water-stop position, the inner cavity of the impact water flow net can also be connected to the inner cavity of the filter screen through the side water outlet, allowing the scale and silt inside the impact water flow net to be carried into the space between the impact water flow net and the filter screen by the action of the flowing water.

[0018] Fourth, the impact water flow net is rotatably connected to the guide rod, and by setting a support net with swirling blades, the impact water flow net rotates under the action of water flow after the guide rod is pressed, so as to realize the jet scouring of the inside of the filter screen 360 degrees.

[0019] Compared with the prior art, this utility model has a discharge rod, which allows the mud, sand and scale in the inner cavity of the filter screen to be discharged through the discharge channel by pressing the discharge rod, thus making the cleaning of the filter screen simpler.

Detailed Implementation

[0026] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0027] like Figures 1 to 5As shown, this utility model relates to an easy-to-clean angle valve, comprising an angle valve housing 1 and an inner core 2 installed inside the angle valve housing 1. A filter screen 21 is connected to the inner core 2. An outlet rod 3 is slidably connected inside the inner core 2, and a discharge channel 31 is formed inside the outlet rod 3. The side of the outlet rod 3 has a lateral communication hole 32 communicating with the discharge channel 31. A water-stop ring 33 is provided at one end of the outlet rod 3 inside the filter screen 21. The diameter of the water-stop ring 33 is smaller than the inner diameter of the filter screen 21. The outlet rod 3 has a water-stop position and a slag discharge position. When the outlet rod 3 is in the water-stop position, the water-stop ring 33 blocks the inner cavity of the filter screen 21 from the lateral communication hole 32. When the outlet rod 3 is in the slag discharge position, the water-stop ring 33 separates from the inner core 2 and communicates the inner cavity of the filter screen 21 with the lateral communication hole 32.

[0028] Thus, this utility model relates to an easy-to-clean angle valve. The inner core 2 is installed inside the angle valve housing 1 to control the flow of water. With the use of the angle valve, some mud, sand, and scale accumulate on the inner wall of the filter screen 21. When cleaning is required, pressing the outlet rod 3 switches it from the water-stop position to the slag discharge position, connecting the inner cavity of the filter screen with the side communication hole 32. The mud, sand, and scale are discharged from the discharge channel 31 of the outlet rod 3 with the water flow. After the outlet rod 3 returns to the water-stop position, it remains in the water-stop position under water pressure.

[0029] Preferably, the lateral connecting holes 32 have several distributed circumferentially along the guide rod 3. Solid impurities such as mud, sand, and scale enter the discharge channel 31 through the connecting holes. Providing multiple lateral connecting holes 32 facilitates the smooth discharge of mud, sand, and scale.

[0030] Preferably, a cap 34 is provided at the end of the outlet rod 3 away from the water-stop ring 33. A side channel 341 is formed on the side of the cap 34, and the side channel 341 communicates with the discharge channel 31 of the outlet rod 3. The cap 34 increases the pressing area of ​​the outlet rod 3, making the pressing operation more convenient. At the same time, the side channel 341 on the cap 34 guides the water flow from the discharge channel 31 to the side, allowing the user to easily collect the water with a container.

[0031] Preferably, the angle valve housing 1 further includes a water-passing pipe 4, and the filter screen 21 abuts against the water-passing pipe 4. A water-stop pad 41 is provided on the water-passing pipe 4 outside the water inlet of the angle valve housing 1, or the water-passing pipe 4 abuts against a water-stop valve 5 inside the pipe interface 100. By controlling the axial movement of the water-passing pipe 4, the switching between water flow and closure of the angle valve can be achieved.

[0032] Preferably, such as Figure 3As shown, the guide rod 3 also has an impact water flow net 35 located inside the filter screen 21. The side wall of the impact water flow net 35 has a plurality of jet holes. One end of the impact water flow net 35 also has a support cylinder 36. The side of the support cylinder 36 has a side water outlet 361. The support cylinder 36 extends into the inner cavity of the water-passing pipe 4.

[0033] By setting up the impact water flow net 35, after pressing the guide rod 3, the water flow is concentrated into the impact water flow net 35 and discharged through the jet hole. The jet washes the inner wall of the filter screen 21, allowing scale and silt to be fully discharged. The support cylinder 36 also supports the impact water flow net 35, making the impact water flow net 35 more stable. After the guide rod 3 is reset to the water stop position, the inner cavity of the impact water flow net 35 can also be connected to the inner cavity of the filter screen 21 through the side water outlet 361, so that the scale and silt in the impact water flow net 35 can be carried into the space between the impact water flow net 35 and the filter screen 21 by the action of water flow.

[0034] Preferably, a sealing gasket 37 is provided at the end of the impact water flow net 35 on the outer periphery of the support cylinder 36; when the guide rod 3 is in the slag discharge position, the sealing gasket 37 abuts and seals with the end of the abutting water pipe 4. This allows more water flowing from the abutting water pipe 4 to flow into the impact water flow net 35 during rinsing, resulting in a stronger jet impact force generated by the impact water flow net 35. The user can also manually rotate the guide rod 3 to rotate the impact water flow net 35, achieving 360-degree rinsing.

[0035] Preferably, such as Figure 4 As shown, a first bearing 38 is provided between the impact water flow net 35 and the guide rod 3, and a second bearing 39 (plane bearing) is provided at the end of the impact water flow net 35 on the outer periphery of the support cylinder 36; when the guide rod 3 is in the slag discharge position, the second bearing 39 abuts against the end of the abutting water pipe 4; a swirl vane 362 is formed inside the support cylinder 36; under the drive of the water flow, the impact water flow net 35 rotates relative to the filter screen 21.

[0036] The impact water flow net 35 is rotatably connected to the guide rod 3, and by setting a support net with swirl blades 362, the impact water flow net 35 rotates under the action of water flow after the guide rod 3 is pressed, so as to realize the jet scouring of the inside of the filter screen 21 360 degrees.

[0037] Preferably, such as Figure 1 As shown, a water-stop pad 41 is provided on the water inlet pipe 4 located outside the water inlet pipe of the angle valve housing 1; the water-stop pad 41 can open or block the water inlet pipe as the water inlet pipe 4 moves axially.

[0038] Preferably, the inner core 2 is threadedly connected to the angle valve housing 1 and moves axially as the inner core 2 and the angle valve housing 1 rotate. When the user twists the inner core 2, the spiral moves axially. Preferably, as... Figure 5 As shown, the abutting water pipe 4, located outside the water inlet pipe of the angle valve housing 1, abuts against the inner core of the stop valve 5. When the abutting water pipe 4 pushes the inner core of the stop valve 5 outward, water is supplied; when the inner core of the stop valve 5 retracts backward, water is shut off.

[0039] Compared with the prior art, this utility model, by setting the outlet rod 3, allows the mud, sand and scale in the inner cavity of the filter screen 21 to be discharged through the discharge channel 31 by pressing the outlet rod 3, thus making the cleaning of the filter screen 21 simpler.

[0040] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
