Description

Technical Field

[0001] This application relates to the field of water purification equipment, and in particular to an RO machine with a detachable water outlet. Background Technology

[0002] Currently, RO machines (also known as point-of-use water purifiers) are machines that use the internationally popular reverse osmosis filtration method to pressurize raw water, filter it using physical principles, and then produce pure water that can be directly consumed by humans without adding any compounds.

[0003] An RO (reverse osmosis) machine includes a frame and multiple filter cartridges. Through the filtration effect of the multiple filter cartridges, it purifies the raw water, removes bacteria, viruses, heavy metals and other organic impurities, and can adjust the pH of the raw water, increase the oxygen content of the water, and improve the taste of the water.

[0004] Regarding the aforementioned technologies, there are still some drawbacks: because the water outlet is always exposed to the outside during the use of the RO machine, external bacteria can easily adhere to the water outlet, and over time, a large number of bacteria can grow, affecting the use of the RO machine. Utility Model Content

[0005] In order to facilitate the convenient replacement of the RO machine's outlet, this application provides an RO machine with a detachable outlet.

[0006] This application provides an RO machine with a detachable water outlet, which adopts the following technical solution:

[0007] An RO machine with a detachable water outlet includes a body and a load-bearing base installed at the bottom. The front of the body is equipped with a touch-sensitive control panel and an internal activated carbon filter assembly. An inlet pipe is configured on the outer wall. The top of the body is detachably connected to a water outlet component via a snap-fit ​​structure. The water outlet component includes an arc-shaped guide section and a free-end extension section. The snap-fit ​​structure includes a control ring and at least two arc-shaped units. The control ring is slidably sleeved on the arc-shaped units and has a spiral guide groove inside that engages with the threads of the arc-shaped units.

[0008] By adopting the above technical solutions, the sliding design of the snap-fit ​​structure can realize the quick installation and disassembly of the water outlet component and the body without the need for tools, simplifying the maintenance process. The arc-shaped guide section matches the curvature of the water inlet pipe, reducing water flow resistance, avoiding turbulence, and improving water output efficiency. In addition, multiple arc-shaped units are evenly distributed circumferentially to ensure uniform force on the connection between the water outlet component and the water inlet pipe, preventing loosening or leakage.

[0009] Optionally, the inner circumference of the arc-shaped unit is machined with an annular positioning groove, and the outer wall of the water inlet pipe is integrally formed with a matching and embedded positioning ring, the outer edge of which is rounded.

[0010] By adopting the above technical solution, the positioning ring is embedded in the annular positioning groove to achieve axial and radial double fixation of the water outlet and the water inlet pipe, preventing misalignment; the rounded corner design of the positioning ring reduces installation resistance, avoids damage to the snap-fit ​​structure due to friction, and extends service life.

[0011] Optionally, the arc-shaped unit also has an integrally formed unlocking block at the end away from the water inlet pipe. The unlocking block extends away from the free end extension section. When the control ring slides onto the unlocking block, the unlocking block is in close contact with the free end extension section and the arc shape separates from the water inlet pipe.

[0012] By adopting the above technical solution, the radial contraction of the arc-shaped unit is directly triggered by pushing the control ring to the unlocking block position, realizing one-handed disassembly operation. The unlocking block is only activated when the control ring slides to a specific position, avoiding accidental detachment during daily use.

[0013] Optionally, a limiting ring is integrally formed at the end of the free end extension, with its outer diameter being larger than the inner diameter of the control ring; when the control ring moves axially to the limit position, the control ring moves to the unlocking block and is tightly attached to the limiting ring; the unlocking block is tightly attached to the free end extension.

[0014] By adopting the above technical solution, the limit ring prevents the control ring from sliding excessively and detaching from the water outlet component, ensuring the integrity of the snap-fit ​​structure; when the control ring contacts the limit ring, it provides a tactile prompt, clearly indicating the endpoint of the disassembly operation.

[0015] Optionally, a permanent magnet component is fixedly provided on the side of the limiting block facing the control ring. The permanent magnet component is arranged circumferentially and can form a contact magnetic fixation with the control ring.

[0016] By adopting the above technical solution, the magnetic force enables the control ring to quickly return to the locked position when not in operation, ensuring connection stability; and the magnetic force will also prevent the arc-shaped unit from interfering with the replacement of the water pipe.

[0017] Optionally, the outer wall of the control ring is machined with anti-slip knurling.

[0018] By adopting the above technical solutions, the anti-slip knurling increases friction, making it easier to operate the control ring with wet hands and improving the user experience; the knurling design provides both visual and tactile cues to clearly indicate the location of the operating parts.

[0019] Optionally, a waterproof membrane is adhered to the inner circumference of the arc-shaped unit.

[0020] By adopting the above technical solution, the waterproof membrane covers the joint surface of the annular positioning groove and the positioning ring, preventing water from seeping into the interior of the snap-fit ​​structure; the waterproof membrane isolates water from metal parts (such as arc-shaped units), reducing the risk of corrosion and extending the equipment life.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. Efficient maintenance: The modular snap-fit ​​structure supports quick disassembly and assembly of the water outlet components, making it easy to clean or replace the filter element;

[0023] 2. It adopts a triple protection system of positioning ring, waterproof membrane and spring pressure to eliminate the risk of water leakage.

[0024] 3. Anti-slip knurling, spring return, limit indicator and other designs improve ease of use and safety, ultimately forming a highly reliable and easy-to-maintain RO machine structure. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] This application discloses an RO machine with a detachable water outlet. (Refer to...) Figure 1 , Figure 2 A RO machine with a detachable water outlet includes a body 1 and a support base 2. The front of the body 1 is equipped with a touch control panel 3 for operating water filtration, water volume adjustment and status display; the body 1 integrates two activated carbon filter cartridges 4 for water purification; and its outer wall is equipped with an inlet pipe 5 for connecting to an external water source.

[0033] A water outlet component 7 is also provided on the top of the body 1, which can be detachably connected via a snap-fit ​​structure 6. The water outlet component 7 consists of an arc-shaped guide section 8 and a free-end extension section 9. The arc-shaped guide section 8 is adapted to the curvature of the water inlet pipe 5 to ensure that the water flow is turbulent. The free-end extension section 9 extends outward to form a water outlet, and the end of this section can be connected to a faucet or used for direct water dispensing.

[0034] Reference Figure 1 , Figure 2 as well as Figure 3 The snap-fit ​​structure 6 connected to the free end extension 9 includes: a control component sleeved on the outside of the water outlet 7 and machined with anti-slip knurling 19, and at least two arc-shaped units 11 (four arc-shaped units 11 are provided in this embodiment). The arc-shaped units 11 are evenly distributed circumferentially at the connection between the water outlet 7 and the water inlet pipe 5, and each arc-shaped unit 11 has an annular positioning groove 13 machined on its inner circumference. An annular positioning groove 13 is also provided in the arc-shaped unit 11. The outer wall of the water inlet pipe 5 is integrally formed with a positioning ring 14 that fits the positioning groove 13. The outer edge of the positioning ring 14 is designed with rounded corners 15 for easy installation guidance. When the user uses the arc-shaped unit 11 to approach the water inlet pipe 5, the positioning ring 14 aligns with the positioning groove 13 and is embedded in the positioning groove 13. At this time, the side walls of adjacent arc-shaped units 11 are tightly attached to each other to form a cylinder that wraps around the water inlet pipe 5.

[0035] Reference Figure 3 , Figure 4 as well as Figure 5 Inside the control ring 10, a spiral guide groove 12 is provided that engages with the threaded arc-shaped unit 11. When the control ring 10 slides axially and adheres to the arc-shaped unit 11, the spiral guide groove 12 engages with the threaded arc-shaped unit 11, driving the arc-shaped unit 11 to contract radially, thereby locking the water outlet 7 and the water inlet pipe 5 and preventing water leakage from the gap between the water outlet 7 and the water inlet pipe 5. To improve waterproof performance, a waterproof membrane (not shown in the figure) is also adhered to the inner circumference of the arc-shaped unit 11. The waterproof membrane covers the annular positioning groove 13 and the surrounding area to prevent water from seeping into the snap-fit ​​structure 6 or to prevent water from leaking out of the body 1. The rounded corner 15 design of the positioning ring 14 can further reduce the frictional resistance during installation, and at the same time, it forms a double seal with the waterproof membrane.

[0036] like Figure 3 , Figure 4 as well as Figure 5 As shown, each arc-shaped unit 11 has an integrally formed unlocking block 16 at the end away from the water inlet pipe 5, and the unlocking block 16 extends in the opposite direction to the free end extension section 9. When it is necessary to disassemble the water outlet component 7, simply rotate the control ring 10 and slide it axially to the position of the unlocking block 16. At this time, the unlocking block 16 is squeezed by the control ring 10, which forces the arc-shaped unit 11 to contract radially, so that the positioning ring 14 disengages from the annular positioning groove 13, and the water outlet component 7 can be removed as a whole.

[0037] A limiting ring 17 is integrally formed at the end of the free end extension 9, and the outer diameter of the limiting ring 17 is larger than the inner diameter of the control ring 10. When the control ring 10 slides towards the free end extension 9 to its limit position, the control ring 10 and the limiting ring 17 are tightly attached to each other, preventing the control ring 10 from detaching from the water outlet 7. In addition, a permanent magnet assembly is fixedly connected to the control ring 10 in the direction of the limiting ring 17. In this embodiment, the permanent magnet assembly is a neodymium iron boron magnet. The magnetic force allows the control ring 10 to quickly return to the locked position in the non-operating state, ensuring connection stability; and under the action of the magnetic force, the arc-shaped unit 11 will not interfere with the replacement of the water pipe.

[0038] The implementation principle of an RO machine with a detachable water outlet disclosed in this application embodiment is as follows:

[0039] When installing the water outlet component 7, align the arc-shaped guide section 8 of the water outlet component 7 with the water inlet pipe 5, and gently push it so that the positioning ring 14 is embedded in the annular positioning groove 13 of the arc-shaped unit 11. The spring pushes the control ring 10 to reset, and the spiral guide groove 12 engages and locks with the arc-shaped unit 11.

[0040] When disassembling the water outlet component 7, manually pull the control ring 10 along the axial direction to the unlocking block 16. The arc-shaped unit 11 will retract, and the positioning ring 14 will disengage, allowing the water outlet component 7 to be removed for cleaning or replacement.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
