Description

[0001] This application is a divisional application of application filed on April 21, 2022, with application number 202210421878.7 and invention title "An Easy-to-Clean Water Inlet Connector and Faucet". Technical Field

[0002] This invention relates to the field of bathroom faucets, and particularly to an easy-to-clean water inlet connector and faucet. Background Technology

[0003] Common shower inlet curved shower stands include those without a filter and those with a pre-filter.

[0004] Among them, the curved foot without filtration function is the most common water inlet connector curved foot on the market. It does not have a pre-filtration function and cannot filter water to protect water-using equipment. When used with a shower faucet, a filter screen needs to be installed at the shower faucet fixing nut or control valve core. However, it is easy to clog when used in areas with poor water quality. After clogging, the main valve can only be turned off and the faucet can be disassembled, which is not easy to disassemble and clean.

[0005] For curved feet with pre-filter function, some are exposed outside the curved foot decorative cup, which is large and affects the overall shape of the product; others use a nut inside the curved foot decorative cup to install a flat gasket filter screen to filter water impurities and protect the shower faucet. However, the flat gasket filter screen has a small water passage area and is easy to clog. Moreover, to remove it for cleaning, the main valve must be turned off first, and then the faucet must be removed to take out the flat gasket filter screen for cleaning. The disassembly, assembly and cleaning of this kind of filter structure are very troublesome. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an easy-to-clean water inlet connector that is easy to disassemble and clean, and can automatically shut off the water circuit when the water filter switching component is removed.

[0018] As an improvement to the above solution, the filter frame is provided with a connecting column, the top rod passes through the connecting column and is threadedly connected to the connecting column, and a second sealing ring is sleeved on the top rod to abut against the inner wall of the connecting column in the circumferential direction.

[0019] The top rod has a drive groove on one end face near the button, and the button has a drive rod that extends into the drive groove. Driving the button to rotate can cause the top rod to rotate relative to the connecting column and generate axial displacement.

[0020] As an improvement to the above solution, the filter frame is provided with a connecting column, the top rod passes through the connecting column and is threadedly connected to the connecting column, and a second sealing ring is sleeved on the top rod to abut against the inner wall of the connecting column in the circumferential direction.

[0021] The button includes a body and a cap. The transition surface is disposed on the body. The body has an operating channel. The cap covers the operating channel and is detachably connected to the body. The end face of the push rod near the cap has a drive groove.

[0022] As an improvement to the above solution, the transition surface includes a first frustum and a cylindrical surface, wherein the larger diameter end of the first frustum is connected to the end of the cylindrical surface away from the second elastic reset member; or

[0023] The angle between the transition surface and the axial direction of the button gradually increases in the direction away from the second elastic reset member.

[0024] As an improvement to the above solution, the filter frame is provided with a stiffening plate connecting the connecting column, and the second elastic reset member is sleeved outside the connecting column and abuts against the stiffening plate.

[0025] As an improvement to the above solution, the surface of the water stop plug opposite to the water guide hole is a spherical surface, a conical surface or a second frustum surface, and the end of the water guide hole near the water inlet cavity is provided with an arc surface adapted to the water stop plug.

[0026] The water stop plug has a water storage tank on the side opposite to the water guide hole, and the first elastic reset member extends into the water storage tank and abuts against the water stop plug.

[0027] As an improvement to the above solution, the water inlet cavity is provided with a second installation port, the second installation port is provided with a water-sealing plug, and the two ends of the first elastic reset member abut against the water-stop plug and the water-sealing plug respectively.

[0028] As an improvement to the above solution, a decorative cup is also included. The connector body includes a water inlet pipe communicating with the water inlet cavity and a water outlet pipe communicating with the water outlet cavity. The decorative cup is sleeved on the water outlet pipe and covers the first installation port and the second installation port. The decorative cup is provided with a button operation hole corresponding to the button.

[0029] In addition, the present invention also provides a faucet, which includes a faucet body and the aforementioned easy-to-clean water inlet connector, wherein the water outlet chamber of the connector body is connected to the water inlet end of the faucet body.

[0030] Implementing this invention has the following beneficial effects:

[0031] The present invention provides a water-stop plug and a first elastic reset member for sealing the water guide hole in the water inlet cavity, a first installation port in the water outlet cavity, a positioning groove in the first installation port, a top rod, a second elastic reset member and a button in the filter cylinder, and a ball bearing inserted through its side wall. The filter cylinder is passed through the first installation port and extended into the water outlet cavity. By pressing the button in the filter cylinder, the button moves axially in the filter cylinder. The transition surface of the button abuts against the ball bearing, causing the ball bearing to disengage from or be inserted into the positioning groove.

[0032] When the entire water filter switching assembly is inserted into the first installation port and the ball bearings are engaged in the positioning groove, the water filter switching assembly is assembled with the connector body, making installation convenient.

[0033] The installed water filtration switching assembly has its filter cylinder abutting against the partition plate, and the push rod pushes the water stop plug away from the water guide hole to allow water to enter. The filter screen of the filter cylinder performs the water filtration function and is not easy to clog.

[0034] When the ball disengages from the positioning groove, the entire water filter switching assembly rebounds outward under the action of the first elastic reset member, allowing the water filter switching assembly to be pulled out from the first installation port, thus enabling convenient disassembly of the water filter switching assembly.

[0035] When the ball disengages from the positioning groove, the interaction between the push rod and the water stop plug is eliminated. The water stop plug seals the water guide hole under the action of the first elastic reset component, realizing the automatic water inlet stop function. The disassembly of the water filter switching component does not require closing the main water valve, which facilitates the disassembly and cleaning of the filter cartridge.

[0036] When the faucet leaks or needs maintenance, there is no need to shut off the main valve; the water inlet can be shut off directly through the water filter switching component, making it convenient to use and maintain.

[0037] The axial movement of the button inside the filter cartridge and the rolling of the ball under the action of the transition surface are not affected by water pressure. The entire water filtration switching component can be popped out by simply pressing the button.

[0038] The opening and closing degree of the spherical stop plug can be controlled by adjusting the length of the top rod extending out of the filter cylinder, which facilitates the adjustment of the flow rate;

[0039] The water-stop plug has a large water-passing area and low flow loss;

[0040] The water-stop plug can automatically guide itself to center and seal the water, and can still seal the water even if it is misaligned, making it highly reliable. Attached Figure Description

[0047] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0048] like Figure 1 As shown, this invention discloses an embodiment of an easy-to-clean water inlet connector, including a connector body 1, a water-stop plug 2, a first elastic reset member 3, and a water filtration switching assembly. Combined with... Figure 2 The connector body 1 has an inlet chamber 11 and an outlet chamber 12. A partition 13 with a water guide hole 131 is provided between the outlet chamber 12 and the inlet chamber 11, and the outlet chamber 12 and the inlet chamber 11 are connected through the water guide hole 131. The inlet chamber 11 contains the water stop plug 2 and the first elastic reset member 3. The first elastic reset member 3 abuts against the water stop plug 2, so that the water stop plug 2 blocks the water guide hole 131, preventing water from flowing from the inlet chamber 11 into the outlet chamber 12. Figure 3 and Figure 4 The water filtration switching assembly includes a filter cylinder 4, a button 5, a ball bearing 6, and a second elastic reset member 7. The water outlet chamber 12 has a first mounting port 14. The filter cylinder 4 passes through the first mounting port 14 and extends into the water outlet chamber 12. A top rod 8 is located at one end of the filter cylinder 4 near the partition 13, and the button 5 is located at the other end of the filter cylinder 4. The second elastic reset member 7 is located inside the filter cylinder 4, with both ends abutting against the button 5 and the filter cylinder 4, respectively. The ball bearing 6 passes through the side wall of the filter cylinder 4, and the side wall of the button 5 has a transition surface 511 for abutting against the ball bearing 6. The inner wall of the first mounting port 14 is provided with a positioning groove 141 that is adapted to the ball bearing 6. When the button 5 moves axially in the filter cylinder 4, the ball bearing 6 can disengage from or be inserted into the positioning groove 141. When the ball bearing 6 is inserted into the positioning groove 141, the filter cylinder 4 abuts against the partition plate 13, and the push rod 8 pushes the water stop plug 2 away from the water guide hole 131. When the ball bearing 6 disengages from the positioning groove 141, the entire water filtration switching assembly can be pulled out from the first mounting port 14.

[0049] This embodiment features a water-stop plug 2 and a first elastic reset member 3 for sealing the water guide hole 131 in the water inlet chamber 11, a first mounting port 14 in the water outlet chamber 12, a positioning groove 141 in the first mounting port 14, a top rod 8, a second elastic reset member 7, and a button 5 inside the filter cylinder 4, with a ball bearing 6 passing through its side wall. The filter cylinder 4 is inserted through the first mounting port 14 and into the water outlet chamber 12. By pressing the button 5 inside the filter cylinder 4, the button 5 moves axially within the filter cylinder 4, causing the transition surface 511 of the button 5 to abut against the ball bearing 6, disengaging or engaging the ball bearing 6 in the positioning groove 141. When the entire water filtration switching assembly is inserted into the first mounting port 14 and the ball bearing 6 engages in the positioning groove 141, the water filtration switching assembly completes its assembly with the connector body 1, the filter cylinder 4 abuts against the partition plate 13, and the top rod 8 pushes the water-stop plug 2 away from the water guide hole 131, thus achieving water inlet and water filtration functions. Installation is convenient. Figure 5 and Figure 6 When the ball bearing 6 disengages from the positioning groove 141, under the action of the first elastic reset member 3, the entire water filter switching assembly rebounds outward, allowing the water filter switching assembly to be pulled out from the first mounting port 14. At the same time, the interaction between the push rod 8 and the water stop plug 2 is eliminated. Under the action of the first elastic reset member 3, the water stop plug 2 seals the water guide hole 131, realizing the convenient disassembly of the water filter switching assembly and the automatic water inlet stop function. The disassembly of the water filter switching assembly does not require closing the main water valve, which facilitates the cleaning of the filter cartridge 4.

[0050] In this embodiment, the connector body 1 is provided with an inlet pipe 15 and an outlet pipe 16, wherein the inlet chamber 11 is connected to the inlet pipe 15 and the outlet chamber 12 is connected to the outlet interface pipe.

[0051] In this embodiment, the easy-to-clean water inlet connector is used for shower head water inlet installation. The water inlet pipe 15 is used to connect to the hot and cold water pipes, and the water outlet pipe 16 is used to connect to the shower faucet. The horizontal axis difference between the water inlet pipe 15 and the water outlet pipe 16 is a universal standard design, so that the shower faucet can still be installed normally even if there is a certain range of deviation in the distance between the pre-buried hot and cold water pipes.

[0052] To facilitate the assembly of the first elastic reset member 3 and the water stop plug 2 in the water inlet cavity 11, the water inlet cavity 11 in this embodiment is provided with a second mounting port 17, and the second mounting port 17 is provided with a water sealing plug 9. The two ends of the first elastic reset member 3 respectively abut against the water stop plug 2 and the water sealing plug 9.

[0053] In addition, the easy-to-clean water inlet connector of this embodiment also includes a decorative cup 10. The connector body 1 includes a water inlet pipe 15 communicating with the water inlet chamber 11 and a water outlet pipe 16 communicating with the water outlet chamber 12. The decorative cup 10 is sleeved on the water outlet pipe 16 and covers the first installation port 14 and the second installation port 17. The decorative cup 10 is provided with a button operation hole 101 corresponding to the button 5 to facilitate the installation of the water filter switching component.

[0054] The easy-clean water inlet connector in this embodiment does not change the current standard installation and connection method of the pipe and shower faucet, and the water filter switching component is located inside the decorative cup 10, which has a compact structure and does not affect the overall shape of the product.

[0055] In this embodiment, the first mounting port 14 is positioned opposite to the water guide hole 131. The filter cylinder 4 specifically includes a filter frame 41, and a filter screen 42, a first water sealing ring 43, and a fixing sleeve 44 arranged sequentially along the axial direction of the filter frame 41.

[0056] The filter screen 42 is arranged around the circumference of the filter frame 41. When the filter cylinder 4 abuts against the partition plate 13 and the top rod 8 pushes the water stop plug 2 away from the water guide hole 131, the filter frame 41 with the filter screen 42 covers the area around the water guide hole 131. The filter screen 42 spans the entire water outlet chamber 12. The water flowing out through the water guide hole 131 flows to the water outlet pipe 16 after being filtered by the filter screen 42.

[0057] The first sealing ring 43 abuts against the inner wall of the first mounting port 14 in the circumferential direction, thereby sealing the water outlet 12 with the first mounting port 14.

[0058] The fixing sleeve 44 is sleeved on the button 5. One end of the fixing sleeve 44 is connected to the filter frame 41, and the other end is provided with a first limiting boss 441. The button 5 can move between the first limiting boss 441 and the filter frame 41. The side wall of the fixing sleeve 44 is provided with a ball bearing mounting hole 442, and the ball bearing 6 is movably disposed in the ball bearing mounting hole 442.

[0059] Specifically, one end of the filter frame 41 is provided with a buckle for connecting with the fixing sleeve 44, and the inner wall of the fixing sleeve 44 near the filter frame 41 is provided with an inner hook groove for engaging with the buckle of the filter frame 41.

[0060] The filter frame 41 protrudes into the inner wall of the fixing sleeve 44, which can limit its movement when the button 5 is pressed.

[0061] The inner wall of the first installation port 14 near the water outlet chamber 12 is provided with a second limiting boss 142 that abuts against the filter frame 41. After the water filtration switching component and the connector body 1 are assembled, the filter frame 41 abuts against the second limiting boss 142, and at the same time the ball bearing 6 is inserted into the positioning groove 141, and the filter cylinder 4 abuts against the partition plate 13.

[0062] The filter frame 41 is provided with a connecting column 411, and the filter frame 41 is provided with a rib plate connecting the connecting column 411. The second elastic reset member 7 is sleeved on the outside of the connecting column 411 and abuts against the rib plate.

[0063] The top rod 8 passes through the connecting column 411 and is threadedly connected to the connecting column 411. A second water sealing ring 81 is sleeved on the top rod 8 and abuts against the inner wall of the connecting column 411 in the circumferential direction.

[0064] The sealing effect of the first sealing ring 43 and the second sealing ring 81 can prevent the water in the outlet chamber 12 from entering the first installation port 14. The axial movement of the button 5 in the filter cylinder 4 and the rolling of the ball 6 under the action of contact with the transition surface 511 are not affected by water pressure. Pressing the button 5 easily will pop up the entire water filtration switching component.

[0065] To achieve the adjustment of the inlet water flow rate, the present invention provides two implementation methods: the opening and closing degree of the stop plug 2 is controlled by adjusting the length of the top rod 8 extending out of the filter cylinder 4 near the partition plate 13.

[0066] Combination Figure 3 In one embodiment, the end face of the push rod 8 near the button 5 is provided with a drive groove, and the button 5 is provided with a drive rod 512 extending into the drive groove. Driving the button 5 to rotate can drive the push rod 8 to rotate relative to the connecting column 411 and generate axial displacement.

[0067] Combination Figure 4 In another embodiment, the button 5 includes a body 51 and a cap 52. A transition surface 511 is disposed on the body 51. An operating channel 513 is provided within the body 51. The cap 52 covers the operating channel 513 and is detachably connected to the body 51. A drive groove is provided on one end face of the push rod 8 near the cap 52. By removing the cap 52 and inserting a tool into the drive groove, the push rod 8 can be rotated, adjusting the length of the push rod 8 extending out of the filter cylinder 4, thereby adjusting the position of the stop plug 2 and controlling the water flow.

[0068] The drive slots in the two embodiments above can be common slots such as slotted slots, cross slots, and hexagonal slots.

[0069] When there is a significant pressure difference between the cold and hot water pipes, the ratio of cold to hot water inlet to the shower product will change, resulting in a change in the outlet water temperature. For example, if the temperature control component is adjusted to the original outlet water temperature of 40 degrees Celsius, the actual outlet water temperature will no longer be 40 degrees Celsius, affecting the user experience. This invention addresses the issue of a large pressure difference between the cold and hot water pipes in a user's home. By adjusting the opening and closing degree of the stop plug 2 of the inlet connector with the higher pressure and the water guide hole 131, the ratio of cold and hot water outlets can be balanced, making the actual outlet water temperature closer to the temperature indicated by the temperature control component. This solves the problem of excessively large differences in the inlet flow rates of the cold and hot water pipes affecting the shower product's outlet water temperature experience.

[0070] When the button 5 moves axially within the filter cylinder 4, the ball 6 abuts against different positions of the transition surface 511, thereby changing the relative position of the ball 6 and the positioning groove 141.

[0071] The button 5 slides against the inner wall of the fixed sleeve 44 to prevent the button 5 from swinging and causing different balls 6 to move asynchronously.

[0072] The transition surface 511 of the button 5 can be a connected first frustum surface 511a and a cylindrical surface 511b, with the large-diameter end of the first frustum surface 511a connected to the end of the cylindrical surface 511b away from the second elastic reset member 7.

[0073] With the filter switching assembly and connector body 1 assembled, when button 5 is pressed, button 5 abuts against ball 6 via the large-diameter end of cylindrical surface 511b or first frustum surface 511a (e.g., Figure 1 The ball moves to the small diameter end of the first conical surface 511a and abuts against the ball 6 (as shown). Figure 5 The ball bearing 6 disengages from the positioning groove 141, and the entire water filter switching assembly unlocks from the first mounting port 14; see also Figure 6 When the button is released, the first elastic reset member 3 immediately drives the water stop plug 2 to stop the water, and drives the water filter switching component to rebound.

[0074] When assembling the water filter switching component with the connector body 1, press again. Figure 6 Button 5 is pressed and the water filter switching assembly is inserted into the first mounting port 14 until the filter frame 41 of the water filter switching assembly abuts against the second limiting boss 142. At this time, button 5 is released. When the second elastic reset member 7 drives button 5 to reset, button 5 abuts against the ball 6 from the small diameter end of the first frustum surface 511a (as shown). Figure 5 The ball moves to the large diameter end of the first frustum 511a, and the cylindrical surface 511b abuts against the ball 6 (as shown). Figure 1 As the ball bearing 6 is gradually squeezed into the positioning groove 141, the filter cylinder 4 abuts against the partition plate 13, and the push rod 8 pushes the water stop plug 2 away from the water guide hole 131, thus opening the water filtration function.

[0075] The transition surface 511 of the button 5 can also be continuously and uniformly varied, and the angle between it and the axial direction of the button 5 gradually increases in the direction away from the second elastic reset member 7.

[0076] When the water filter switching assembly and the connector body 1 are assembled, when the button 5 is pressed, the button 5 moves from the end of the transition surface 511 and the button 5 with a smaller axial angle to the end of the transition surface 511 and the button 5 with a larger axial angle to the end of the transition surface 511 and the button 5 with a larger axial angle, and the ball 6 disengages from the positioning groove 141, and the entire water filter switching assembly is unlocked from the first mounting port 14; when the button is released, the first elastic reset member 3 drives the water stop plug 2 to stop the water, and drives the water filter switching assembly to rebound.

[0077] When assembling the water filter switching assembly with the connector body 1, press button 5 and insert the water filter switching assembly into the first mounting port 14 until the filter frame 41 of the water filter switching assembly abuts against the second limiting boss 142. At this time, release button 5. When the second elastic reset member 7 drives button 5 to reset, button 5 moves from the end of the transition surface 511 and the button 5 with a larger axial angle abutting against ball 6 to the end of the transition surface 511 and the button 5 with a smaller axial angle abutting against ball 6. Ball 6 is gradually squeezed and stuck into the positioning groove 141. At this time, filter cylinder 4 abuts against partition plate 13, and top rod 8 pushes water stop plug 2 away from the water guide hole 131, and the water filtration function is turned on.

[0078] The diameter of the ball bearing mounting hole 442 is preferably gradually increased from the inner wall to the outer wall of the fixing sleeve 44, so that the ball bearing 6 maintains the tendency to roll towards the button 5 inside the fixing sleeve 44, ensuring that the ball bearing 6 can smoothly disengage from the positioning groove 141.

[0079] In this embodiment, the surface of the water-stop plug 2 opposite to the water guide hole 131 is a spherical surface, a conical surface, or a second frustum surface. The end of the water guide hole 131 near the water inlet cavity 11 is provided with an arc surface adapted to the water-stop plug 2. The spherical, conical, and second frustum surface sealing structures can automatically guide and center the water-stopping mechanism, ensuring water sealing even if the water-stop plug is misaligned. This avoids the problem of existing T-shaped rod water-stop plug structures failing to seal due to water impact and eccentricity. The automatic water-stopping function of the water-stop plug 2 in this application has high reliability.

[0080] In addition, the spherical sealing water-stop structure has a large water passage area and low flow loss.

[0081] To protect the surface of the water-stop plug 2, the top rod 8 in this embodiment is provided with a sleeve 82 for contacting the surface of the water-stop plug 2.

[0082] The water stop plug 2 has a water storage tank 21 on the side opposite to the water guide hole 131. On the one hand, it can facilitate the installation of the first elastic reset member 3, which extends into the water storage tank 21 and abuts against the water stop plug 2. On the other hand, the water pressure of the water inlet chamber 11 can help to make the water stop plug 2 fit with the water guide hole 131 of the partition 13 to seal the water.

[0083] This invention also discloses a faucet, which includes a faucet body and the aforementioned easy-to-clean water inlet connector, wherein the water outlet chamber of the connector body is connected to the water inlet end of the faucet body. When the faucet leaks or requires maintenance, the water inlet can be directly shut off via the water filter switching component without closing the main valve, making it convenient to use and maintain.

[0084] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
