Description

Technical Field

[0001] The utility model relates to the technical field of hardware accessories, in particular to a faucet inner core. Background Art

[0002] Inner core. The inner core of the faucet is made of copper, which does not contain diamonds. The main body of the faucet refers to the faucet body. In the early days, it was mainly made of bronze, but now it is mostly made of brass. Faucets are mainly divided into imported and domestically produced. Imported faucets have no pores, while domestically produced faucets have many defects in technology, and their wear resistance and corrosion resistance are not as good as imported faucets. The faucet is one of the most frequently used kitchen and bathroom equipment in every family.

[0003] Among them, the "faucet core" disclosed in the application number "CN202121726217.2" is also an increasingly mature technology. Its "this solution can fix the packaging paper during the cutting process of the packaging paper waste edges. The upper end of the placement plate is fixedly connected with an anti-slip pad, which can increase the friction force. The lower end of the fixed block is fixedly connected with an elastic protection block, which can play a buffering and protective role for the packaging paper." However, the collection device still has the following defects during use: the collection device cannot perform a crushing operation when collecting the packaging paper waste edges, so it may affect the collection amount of the packaging paper waste edges. Based on this, it is necessary to provide a device that can crush the packaging paper waste edges and increase the collection amount. In addition, the traditional faucet core is easy to damage and is not conducive to personnel maintenance in the later stage. In addition, the disassembly and assembly process of the faucet core is relatively complicated and cumbersome, and long-term manual use in the later stage will cause the valve head of the faucet to wear and cause damage. In addition, the later maintenance and corresponding treatment of the faucet in the scheme are relatively complicated and separated from the internal faucet core. It is generally difficult to dismantle and separate, resulting in increased maintenance and repair costs, and the qualified rate after later recycling and reprocessing is not high.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1 - Figure 8 The utility model provides a faucet inner core, including a metal faucet mechanism 1, a faucet inner core mechanism 2 and an adapting mechanism 3;

[0033] The metal faucet mechanism 1 is used to wrap the outer metal tube of the protective faucet inner core mechanism 2, and the metal faucet mechanism 1 can be disassembled, and the adapter mechanism 3 is adapted to the threaded installation faucet inner core mechanism 2, which is an integrated threaded installation;

[0034] The metal faucet mechanism 1 comprises an outermost three-way pipe fitting 11 , one end of which is provided with a conical seat 12 , a circular opening 13 is provided in the middle of the end of the conical seat 12 , and an inner thread 14 is provided at the edge of the other end of the three-way pipe fitting 11 .

[0035] In this embodiment: a limiting screw sleeve 15 is threadedly installed at one end of the embedded thread 14, one end of the limiting screw sleeve 15 is threadedly adapted and installed with the inner wall thread of the embedded thread 14, and a nut head 16 is provided at the end position of the limiting screw sleeve 15, and one end of the nut head 16 is threadedly fastened to the embedded thread 14.

[0036] The purpose of the adopted limiting screw sleeve 15 and the embedded thread 14 is to facilitate manual disassembly and installation of the faucet valve core.

[0037] In this embodiment, the side wall of the three-way pipe fitting 11 is precisely cut with an arc notch 17, and the end side wall of the arc notch 17 is adapted to be threadedly connected with a through-type end pipe 18, and the inner side wall of the end of the through-type end pipe 18 is threadedly installed with a pipe connection thread 19.

[0038] The through-type end pipe 18 and the arc-surface notch 17 are adopted to complete the installation of the valve head part for controlling the inner core of the faucet.

[0039] In this embodiment: the faucet inner core mechanism 2 includes a water diversion inner core valve tube 21 adapted to the inside of the three-way pipe fitting 11, a pull-out pipe groove 22 is provided on the back of the pipe fitting, and a lift piece 23 is provided at the end of the groove beam of the pull-out pipe groove 22, and the lift piece 23 and the side wall of the pull-out pipe groove 22 are adapted to slide with the inner wall of the three-way pipe fitting 11.

[0040] The main function of the pipe drawing groove 22 and the specific lifting piece 23 is to reduce the contact between the groove and the pipe wall so that the pipe can be pushed into the interior of the three-way pipe fitting 11 more smoothly and reduce friction damage.

[0041] In this embodiment: the left end pipe of the water diversion inner core valve pipe 21 is connected to a three-tube assembly 231, two of which are water inlet end pipes 24, and the side walls of the two water inlet end pipes 24 are coordinated with the water inlet hole regulating valve seats 241 set on the side walls.

[0042] The three-tube assembly 231 is mainly used to ensure that the water outflow and water inflow inside the tube body are more integrated and precise.

[0043] In this embodiment, the top end of the water inlet pipe 24 is also connected to a water outlet pipe 25 , and the side wall of the water outlet pipe 25 is connected to a water outlet hole regulating valve seat 251 through a valve core to guide the liquid from the water inlet pipe 24 to the water outlet pipe 25 .

[0044] The purpose of the water outlet pipe 25 and the water outlet regulating valve seat 251 is to ensure that the water is guided more conveniently.

[0045] In this embodiment: the water outlet regulating valve seat 251 and the water inlet regulating valve seat 241 are installed with a valve core water regulating assembly 26, and the edge of the valve core water regulating assembly 26 is also sleeved with an arc-shaped connecting piece 27, the surface edge notch of the arc-shaped connecting piece 27 is adapted to fit with the surface of the arc-shaped notch 17, and one end of the through-type end pipe 18 is fitted with the side of the arc-shaped connecting piece 27.

[0046] The main purpose of adopting the through-type end pipe 18 and the specific arc-shaped connecting piece 27 is to clamp the entire inner core valve when the arc-surface notch 17 is inserted later.

[0047] In this embodiment: the side wall of the valve core water regulating assembly 26 is also installed with two arc-shaped limiting clamps 28, and the middle part of one of the arc-shaped limiting clamps 28 is provided with an adapting groove 29 for adapting installation;

[0048] The adapter mechanism 3 includes a resistance gasket 31 installed at the other end of the water diversion inner core valve tube 21, a pipe sleeve 32 is sleeved in the middle of the end of the resistance gasket 31, a sleeve 33 is transversely installed in the middle of the pipe sleeve 32, and a support sleeve 34 is connected to the middle of the end of the sleeve 33.

[0049] The sleeve 33 and the support sleeve 34 used play a role in limiting the connection of the pipe mouth and preventing the pipe mouth from dislocating and rotating.

[0050] In this embodiment, an adapting port 35 is disposed at the end of the support pipe sleeve 34 , and a threaded head 36 is installed at the end of the adapting port 35 , and one end of the threaded head 36 passes through the circular opening 13 .

[0051] The purpose is to make the subsequent clamping phase of the threaded head 36 more precise.

[0052] When used specifically, step 1: the metal faucet mechanism 1 is connected to one end of the three-way pipe fitting 11 by pipe connection;

[0053] First, in order to improve the initial design of the faucet core, it is easy to recycle and disassemble it when it is damaged, or to make the classification and disassembly of the faucet core more convenient for maintenance;

[0054] First disassemble the metal faucet mechanism 1;

[0055] After the nut head 16 of the embedded thread 14 is unscrewed to disassemble the limiting screw sleeve 15, the through-type end pipe 18 is disassembled, and the port of the through-type end pipe 18 is pulled out from the arc surface notch 17. In this way, the exposed embedded thread 14 will have a large pipe opening space. Manually, only the thread head 36 needs to be pressed. At this moment, the integrated faucet inner core mechanism 2 will be directly disengaged from the embedded thread 14 position at the other end of the three-way pipe fitting 11;

[0056] In order to ensure a smoother disengagement process, the water-introducing inner core valve tube 21 and its pulling-out tube groove 22 at this moment will guide the entire faucet inner core mechanism 2 to disengage more smoothly, and the abutting gasket 31 will also slide with the tube wall of the three-way pipe fitting 11, combined with the linear guiding effect of the tilting piece 23 and the inner arc-shaped limiting clamp 28, it will ensure that the adapter grooves 29 on both sides and one end of the arc-shaped limiting clamp 28 slide back and forth, and under the sliding, the friction with the inner wall of the three-way pipe fitting 11 will be reduced, so that the faucet inner core mechanism 2 can be pushed more smoothly to avoid being stuck. In addition, the same principle is used for putting it back, and the same effect is achieved, with guiding adaptation;

[0057] Since the conical seat 12 gradually shrinks into a conical state, it also plays a sealing and clamping role when resetting;

[0058] This can greatly facilitate the manual operation when the user returns it later, and the inner core and the three-way pipe fitting 11 will not be deformed to varying degrees due to internal space caused by violent disassembly when the pipe is connected to the outlet pipe later, or the joint part will be deformed to varying degrees, thereby reducing the scrap rate;

[0059] Step 2: Reinstall;

[0060] The staff needs to insert the end of the threaded head 36 from the slightly larger end opening of the three-way pipe fitting 11. After inserting it, the staff will continue to fine-tune it manually to make the valve core water regulating component 26 of the valve core water regulating component 26 gradually turn to the arc surface notch 17 position, and then tighten the through-type end pipe 18 manually to let the through-type end pipe 18 be inserted into the inside of the arc surface notch 17, and use the edge of the arc-shaped connecting piece 27 to achieve the interlaced and fastened connection with the inner wall of the through-type end pipe 18. After that, the end side walls of the pulling pipe groove 22, the water inlet end pipe 24 and the water outlet end pipe 25 at this moment fit and slide with the middle inner wall of the three-way pipe fitting 11 to reduce friction, and then until the interference gasket 31 moves to the position of the conical seat 12, the change in the inner diameter will gradually play a role in limiting, and the remaining components: the pipe sleeve 32, the sleeve 33 and the adapter port 35 will gradually pass through the circular opening 13 and reach the appropriate position and then automatically and accurately engage;

[0061] After the thread plug is well embedded in the thread 14 and the thread of the nut head 16 is tightened, the assembly is completed;

[0062] Step 3: Use:

[0063] When using, the manual operation only needs to fit the water filling pipe of the faucet inner core, and install the water regulating valve on the pipe thread 19 position.

[0064] Toggle the valve body itself. At this point, we need to explain: the direction of water flow;

[0065] Water inlet:

[0066] The ball valve assembly plugged in the valve core water regulating assembly 26 will gradually open after the valve body structure installed by the water inlet regulating valve seats 241 on both sides is toggled, because the two water inlet end pipes 24 will put water in from the pipe mouth position with the copper sheet, and then the water will gather from the inside of the water diversion inner core valve pipe 21, and at this moment of gathering, it will reach the position of the water outlet end pipe 25 (understanding water outlet means that the tops of the two water inlet end pipes 24 are both provided with water outlets), and then accumulate and uniformly inject into the water outlet end pipe 25 to realize water outlet, and when the water outlet is discharged, the liquid water outlet will be realized due to the state of the water outlet regulating valve seat 251;

[0067] Step 5: Solve the pain points;

[0068] The first generation of conventional faucet inner core is prone to damage at the following locations: the arc notch 17 and the contact position of the through-type end pipe 18. This part will be squeezed and deformed if not carefully maintained during long-term multi-pipe connection, resulting in leakage when the valve body is repeatedly turned to release water. The gap is too large and the probability of disassembly damage is high. Therefore, the combined arc-shaped connecting piece 27 can improve the toughness of this part.

[0069] The combined pull-out pipe groove 22 and the water outlet pipe 25 greatly facilitate manual disassembly of subsequent parts, avoiding obstructions during disassembly or damage to the piston.
