Referring to fig. 1, in an embodiment of the present invention, the faucet 100 may include a main body 10, a valve core 20 connected to the main body 10, an opening degree detecting device 30 for detecting an opening degree of the valve core 20, a handle 40 for driving the valve core 20 to open and close, and a water outlet pipe 50 connected to the main body 10.

The body 10 of this embodiment is generally cylindrical and may be made of stainless steel, cast iron, alloys, or the like. The body 10 may include a top wall 12, a bottom wall 14, and a side wall 16 connected between the top wall 12 and the bottom wall 14. The main body 10 is provided inside with a water flow path 11 and a receiving chamber 13.

As shown in FIG. 2, the water flow path 11 may include an inlet passage 110 and an outlet passage 112, the inlet passage 110 extending through the bottom wall 14 and the outlet passage 112 extending through the top wall 12. Specifically, the inlet passage 110 is in communication with an inlet pipe (not shown), and the outlet passage 112 is in communication with the outlet pipe 50. Water enters the inlet passage 110 of the main body 10 from the inlet pipe, and then is discharged from the outlet pipe 50 through the outlet passage 112.

The accommodation chamber 13 is opened between the water inlet passage 110 and the water outlet passage 112, and communicates with the water inlet passage 110 and the water outlet passage 112. The receiving cavity 13 of the present embodiment extends along a direction substantially perpendicular to the side wall 16, and one end of the receiving cavity 13 penetrates through the side wall 16 to form a mounting opening on the side wall 16.

In the main body 10 of this embodiment, an outer peripheral wall 160 protruding outward of the main body 10 is provided at the outer periphery of the mounting opening with respect to the side wall 16, and a screw thread is provided on the inner surface of the outer peripheral wall 160.

The sidewall of the main body 10 may further have a groove 163, and the groove 163 may be annular, and the groove 163 surrounds the outer peripheral wall 160. The inner wall of the recess 163 is provided with a mounting groove 165.

The shape and structure of the main body of the above-mentioned embodiment are only an example of the present invention, and in other embodiments, the main body may have other shapes or have other structures, which is not limited by the present invention.

In some embodiments, a nut 61 and a jaw 62 are provided at one end of the water inlet passage 110, and the water inlet pipe can be stably coupled to the body 10 by the engagement of the nut 61 and the jaw 62. Further, a packing 63 is provided in the water inlet passage 110 to seal the water inlet pipe to the main body 20, thereby preventing water leakage from the water inlet passage 110 of the main body 10.

The outlet pipe 50 may have various shapes, for example, a straight pipe shape, a C-bent pipe shape, an L-bent pipe shape, etc. The water outlet pipe 50 may be made of stainless steel, alloy, etc. with high rigidity, or may be a silicone hose or other plastic hose with low rigidity. A shower head, a filter head and the like can be arranged at the water outlet end of the water outlet pipe 50.

A positioning member may be provided at the junction of the water outlet pipe 50 and the main body 10. For example, a clamping ring 64 is sleeved on the outlet pipe 50 to connect the outlet pipe 10 to the main body 10 by clamping the clamping ring 64 with the main body 10, and to position the outlet pipe 50 along the axial direction of the outlet pipe 50. In addition, a sealing ring 63 is disposed between the main water pipe 50 and the main body 10 to seal the water outlet pipe 50 to the main body 10, thereby preventing water leakage at the end of the water outlet passage 112.

The valve body 20 can control the flow rate of water in the water flow passage 11 by opening and closing operations with respect to the main body 10. The opening and closing motion of the valve core 20 may be linear motion, rotation or other motion relative to the main body 10.

The valve body 20 shown in fig. 2 is opened and closed by rotating with respect to the main body 10 to control the amount of water in the water flow passage 11. Specifically, the valve body 20 is provided with a water passage 21 inside. When the valve member 20 is rotated so that the water inlet of the water passage 21 is not communicated with the water inlet passage 110 of the main body 10 or the water outlet of the water passage 21 is not communicated with the water outlet passage 112 of the main body 10, the water passage 11 in the main body 10 is blocked, and the faucet 100 is correspondingly closed. When the valve member 20 is rotated to communicate the water inlet and the water outlet of the water passage 21 with the water inlet passage 110 and the water outlet passage 112, respectively, the water passage 11 in the main body 10 is connected and the faucet 100 is opened. The rotary valve body 20 can adjust the cross-sectional area of the communication portion between the water inlet and the water outlet of the water passage 21 and the water inlet passage 110 and the water outlet passage 112, and the size of the cross-sectional area can be adjusted to correspond to the size of the water flow rate that can pass.

The valve core 20 of the present embodiment is rotatably installed in the accommodation chamber 13. Specifically, the spool 20 of the present embodiment has a substantially cylindrical shape, the spool 20 is divided into a first spool section 22, a second spool section 24, and a third spool section 26 in this order in the axial direction of the spool 20, and the cross-sectional areas of the first spool section 22, the second spool section 24, and the third spool section 26 are gradually reduced, so that a step structure is formed on the surface of the spool 20. The compression nut 65 is fitted over the second spool section 24 of the spool 20. The compression nut 65 is provided with an external thread which cooperates with an internal thread on the outer peripheral wall 160 of the body 10 so as to clamp the first spool segment 22 of the spool 20 in the accommodation chamber 13.

The valve core 20 is fixed on the handle 40, so that the valve core 20 is driven by the handle 40 to open and close relative to the main body 10. The handle 40 of this embodiment is fixedly connected to the third spool section 26 of the spool 10.

Specifically, the handle 40 may include a handle tray 42 and a handle bar 44. The handle tray 42 includes a bottom wall 422 and a side wall 424 attached to the outer periphery of the bottom wall 422. The valve core 20 is fixed to the bottom wall 422. The handle lever 44 is secured to the side wall 424 by a lock nut 66 so that the handle disk 42 can be rotated by turning the handle lever 44 to rotate the valve cartridge 20. The end of the side wall 424 of the handle tray 42 remote from the bottom wall 422 is provided with a mounting bracket 426, which mounting bracket 426 projects from the handle tray 42 relative to the side wall 424 in a direction away from the bottom wall 422.

The opening degree detection device 30 detects the opening degree of the valve body 20. The opening degree of the valve body 20 may be the degree of communication between the water passage 21 of the valve body 20 and the water passage 11 of the main body 10. The detection of the opening degree of the valve element 20 can be characterized by the degree of relative movement of the valve element 20 with respect to the body 10. For example, if the opening and closing motion of the valve element 20 is a linear motion with respect to the body 10, the opening degree of the valve element may be determined by detecting a linear displacement of the valve element 20 with respect to the body 10. As in the present embodiment, the opening and closing operation of the valve body 20 is a rotation relative to the main body 10, and the opening degree of the valve body 20 can be determined by detecting the rotation angle of the valve body 20 relative to the main body 10.

The opening degree detection device 30 of the present embodiment may include a magnet 32 and a magnetic sensor 34. One of the magnet 32 and the magnetic sensor 34 is fixedly disposed with respect to the body 10, and the other is linked with the spool 20. The mounting positions of the magnet 32 and the magnetic sensor 34 are such that the relative position between the magnet 32 and the magnetic sensor 34 can be changed in accordance with the opening and closing operation of the valve element 20. Also, the magnet 32 is disposed such that the magnetic field strength of the magnet 32 sensed by the magnetic sensor 34 continuously changes with the opening degree of the valve spool 20 when the relative position between the magnet 32 and the magnetic sensor 34 changes. Since the distribution of the magnetic field strength is continuously changed along with the opening degree of the valve element 20, the magnetic sensor 34 can sense the magnetic field strength corresponding to each different position of the magnetic field when moving to the position, so as to output a corresponding detection signal representing the magnetic field strength, and each opening degree value of the valve element 20 corresponds to a relative position of the magnetic sensor 34 and the magnetic field, that is, corresponds to a magnetic field strength, so that the opening degree detection device 30 can accurately detect the opening degree of the valve element 20 by detecting the magnetic field strength.

In some embodiments, magnet 32 may be arranged such that the magnetic field strength sensed by magnetic sensor 34 is linear with the opening of spool 20.

Specifically, the magnitude of the magnetic field strength generated by the magnet 32 may vary gradually along the direction of relative motion of the magnet 32 and the magnetic sensor 34. In some embodiments, the face of the magnet 32 proximate the magnetic sensor 34 may be curved corresponding to the direction of motion between the magnet 32 and the magnetic sensor 34.

For example, if the relative motion between the magnet 32 and the magnetic sensor 34 is along a straight line, the magnetic field of the magnet 32 gradually changes along the straight line, and the surface of the magnet 32 close to the magnetic sensor 34 may be a plane extending along the straight line.

For another example, the opening and closing movement of the valve element 20 in the present embodiment is a rotation relative to the main body, and the relative movement between the magnet 32 and the magnetic sensor 34 is also a rotation, and as shown in fig. 3, the surface of the magnet 32 close to the magnetic sensor 34 may be a curved surface. The curved surface is curved in the rotational direction of the spool 20. The magnetic sensor 34 and the arc surface perform concentric relative rotation.

The magnet 32 in this embodiment may be a permanent magnet, and the magnet 32 may be generally in the shape of an arc, a semicircle, a sector, or an arch, and the invention is not limited thereto. Referring to fig. 4 and 5, the valve core 20 of the present embodiment rotates relative to the main body 10, and therefore, the rotation angle of the valve core 20 relative to the main body 10 needs to be detected, so that the magnet 32 is shaped into an arc, and the center of the arc of the magnet 32 coincides with the rotation axis of the valve core 20. The magnet 32 has a first arc surface 321 and a second arc surface 322 which are opposite to each other, and a first side surface 323 and a second side surface 324 which are connected between the first arc surface 321 and the second arc surface 322 and are opposite to each other. Wherein the first arc surface 321 and the second arc surface 322 are parallel. The first side 323 and the second side 324 are planar.

In some embodiments, the arc of the arc is equal to the arc of rotation of the spool 20. Thus, during the relative rotation of the spool 20 with respect to the body 10, the magnetic sensors 34 are each located in the radial direction of the arc surface, so that the magnetic sensors 34 can each sense the magnetic field strength of the magnet 32 during the rotation of the magnetic sensors 34 with respect to the magnet 32.

The magnet 32 of the present embodiment is magnetized in the radial direction, that is, the magnetic poles of the magnet 32 are arranged on two opposite sides of the magnet 32 in the radial direction of the arc surface, and the magnitude of the magnetic field intensity generated by the magnet 32 gradually changes in the circumferential direction of the arc surface.

As shown in fig. 4 and 5, in the circumferential direction of the arc surface, the magnet 32 is divided into a first magnet segment 325 and a second magnet segment 326 which are connected to each other, and the magnetic pole directions of the first magnet segment 325 and the second magnet segment 326 are opposite to each other, and the magnitude of the magnetic induction generated by the magnet 32 gradually increases from the connection of the first magnet segment 325 and the second magnet segment 326 to both ends of the magnet 32. In the radial direction of the arc, the magnetic poles on both sides of the magnet 32 are opposite. For example, in the first magnet segment 325, the magnetic pole on the first arc surface side is an N pole, and the magnetic pole on the second arc surface side is an S pole. In the second magnet segment 326, the magnetic pole on the first arc surface side is the S pole, and the magnetic pole on the second arc surface side is the N pole.

For example, in the present embodiment, the magnetic induction intensity at the joint of the first magnet segment 325 and the second magnet segment 326 is 0. In the present embodiment, the first magnet segment 325 and the second magnet segment 326 are equal in length, and on the first arc 321 side, the magnetic induction intensity gradually increases to N1000GS from the connection point to the end of the first magnet segment 325; from the junction to the end of the second magnet segment 326, the magnitude of the magnetic induction gradually increases to S1000 GS. That is, the distribution of the magnetic induction intensity of the magnet 32 varies uniformly from N1000GS to 0 to S1000GS from one end of the magnet 32 to the other end thereof, and in the present embodiment, the variation may be a linear variation. Therefore, the magnetic induction intensity also varies linearly from one end to the other end of an arc line segment formed by points of equal radius in the radial direction of the arc magnet 32.

In other embodiments, the lengths of first magnet segments 325 and second magnet segments 326 may not be equal.

The shape and structure of the magnet are only an example of the present invention, and the magnet may have other shapes and structures, and the present invention is not limited thereto. It is understood that in other embodiments, the magnet may also be magnetized in other directions, and the position of the magnetic sensor is changed accordingly, so as to ensure that the magnetic field strength sensed by the magnetic sensor continuously changes with the opening degree of the valve core when the relative position between the magnet and the magnetic sensor changes.

The magnetic sensor 34 outputs a detection signal as long as it is within the magnetic coupling range of the magnet 32, and the detection signal changes in accordance with the change in the magnetic induction intensity. If the magnetic sensor 34 and the magnet 32 are relatively fixed, the detection signal is not changed; when the magnetic induction intensity of the magnet 32 changes on the trajectory of the relative movement when the two move relatively, the detection signal output by the magnetic sensor 34 also changes in accordance with the change in the magnetic induction intensity. So that the magnetic induction of the current position of the magnetic sensor 34 relative to the magnet 32 can be determined from the detection signal, and thus the position of the magnetic sensor 34 relative to the magnet 32 can be determined to determine the angle of rotation of the spool 20 relative to the body 10.

Specifically, one of the magnet 32 and the magnetic sensor 34 may be provided on the body 10, for example, on the outer peripheral wall 160, on the inner wall of the recess 163, or other positions of the body 10. The other of the magnet 32 and the magnetic sensor 34 may then be disposed on the valve cartridge 20, on the handle 40, and in particular, on the handle disc 42, e.g., on the sidewall 424. The handle 40 covers the recess 163, and the magnet 32 or the magnetic sensor 34 mounted on the sidewall 424 of the handle 40 is positioned in the recess 163 and corresponds to the magnetic sensor 34 or the magnet 32 mounted on the mounting groove 165.

In this embodiment, the magnet 32 is disposed on the mounting bracket 426 of the handle plate 42, and the magnetic sensor 34 is disposed in the mounting groove 165 of the inner wall of the recess 163. When the handle 40 covers the recess 163, since the mounting bracket 426 protrudes in a direction away from the bottom wall 422 of the handle tray 42, the magnet 32 mounted on the mounting bracket 426 protrudes into the recess 163 and corresponds to the magnetic sensor 34 mounted on the mounting groove 165.

Specifically, in some embodiments, the opening degree of the spool 20 gradually increases when the movement direction of the magnetic sensor 34 with respect to the magnet 32 is from the end 327 of the first magnet segment 325 to the end 328 of the second magnet segment 326. From one end 327 of first magnet segment 325 to the junction of first magnet segment 325 and second magnet segment 326, the magnitude of the magnetic field strength sensed by magnetic sensor 34 is inversely related to the opening degree of spool 20. That is, during the section of motion, as the opening degree of the spool 20 gradually increases, the magnitude of the magnetic field strength sensed by the magnetic sensor 34 gradually decreases. From the connection point of the first magnet segment 325 and the second magnet segment 326 to one end of the second magnet segment 326, the magnitude of the magnetic field intensity sensed by the magnetic sensor 34 is positively correlated with the opening degree of the spool 20. That is, during this section of motion, as the opening degree of the spool 20 gradually increases, the magnitude of the magnetic field strength sensed by the magnetic sensor 34 gradually increases.

For example, the magnetic sensor 34 may be a hall sensor, and the detection signal thereof may be a hall voltage. In some embodiments, the hall sensor may include a semiconductor sheet and four lead-out terminals, two of which are input terminals for a bias current of the hall element and the other two of which are output terminals for a hall voltage. If the two output terminals form an external loop, a hall current is generated. When a control current is passed across the semiconductor wafer and a magnetic field is applied in the direction perpendicular to the wafer, a potential difference, i.e., a hall voltage, is generated in the direction perpendicular to the current and magnetic fields. When the bias current is fixed, the hall voltage will depend on the strength of the magnetic field being measured. In some embodiments, the hall voltage is amplified by an amplifier in the integrated circuit to enable the voltage to be amplified sufficiently to output a strong signal so that the signal can be observed by a user to determine the strength of the detected magnetic field.

Specifically, the hall sensor outputs a voltage as long as it is within the magnetic coupling range of the magnet 32. When the handle 40 is not rotated, the magnet 32 and the hall sensor are relatively fixed, and the hall voltage output by the hall sensor does not change. When the faucet 100 is to be opened or closed, the rotating handle 40 rotates the valve core 20, and at this time, the magnet 32 provided on the handle plate 42 rotates, the axis of the rotation is concentric with the arc-shaped magnet 32, and the hall sensor provided on the side wall 16 of the main body 10 is fixed. The hall sensor is located at a position in the radial direction of the arc magnet 32, and as the faucet 100 is turned on or off, the arc magnet 32 rotates along with the handle disk 42, and the magnetic field experienced by the hall sensor is a magnetic field from one end to the other end of an arc line segment with a radius equal to the distance between the center of the arc magnet 32 and the hall sensor. The magnetic induction intensity of the magnetic field is changed, and the Hall voltage output by the Hall sensor is changed along with the change of the magnetic induction intensity of the magnetic field. One hall voltage output from the hall sensor corresponds to one magnetic induction, i.e., indicates that the hall sensor is located at one position in the magnetic field, so that the rotation angle of the spool 20 with respect to the main body 10 can be determined. The magnetic induction intensity at the arc segment of the embodiment is linearly changed, and therefore, the hall voltage output by the hall sensor is also linearly changed.

As shown in fig. 6, fig. 6 is a relationship curve between the output signal of the hall sensor and the magnetic induction intensity of the present embodiment. The magnetic induction of the magnet 32 of the present embodiment varies uniformly and linearly in the range of-B to B along the circumferential direction of the magnet 32. When the valve element 20 is rotated, for example, when the valve element 20 is rotated to gradually increase the opening degree thereof, the hall sensor moves relative to the magnet 32 in the circumferential direction of the magnet 32, and the magnetic field strength sensed by the hall sensor linearly changes according to the opening degree of the valve element. The output of the linear hall sensor of this embodiment is linearly changed in the hall voltage range from V0 to V2, and when the N-pole magnetic induction intensity is greater than B, the output is fixed at V0, and when the S-pole magnetic induction intensity is greater than B, the output is fixed at V2. According to the linear relation, if the radian of the magnet is N degrees, the output voltages V0-V2 correspond to 0-N degrees, and the value of the Hall voltage represents the opening degree of the valve core 20, so that the rotating angle of the water faucet 100 can be known by collecting the Hall voltage. The faucet 100 may then be specifically controlled based on the angle of rotation.

After the faucet 100 is used for a long time, in the closed state, the relative position between the valve element 20 and the main body 10 may be shifted, which may cause the magnetic sensor 34 not to be in the radial direction of the arc surface of the magnet 32 in the closed state, and thus the detection signal of the magnetic sensor 34 may not continuously change with the magnetic field at that position, and after the valve element 20 rotates by a certain angle, the magnetic sensor 34 needs to enter the magnetic field with which the detection signal continuously changes, which may eventually cause the detected opening degree of the valve element 20 to be inaccurate. In some embodiments, the arc of the arc surface is set to be greater than the arc of rotation of the valve cartridge 20, and in this way, even if the relative position between the valve cartridge 20 and the main body 10 is shifted when the faucet 100 is in the off state, the magnetic sensor 34 can be located at a magnetic field with which the sensing signal is in a continuously varying relationship, thereby avoiding the problem of inaccurate detection results due to the above-mentioned reasons.

The present invention also provides a water treatment machine 200, as shown in fig. 7, the water treatment machine 200 includes a water treatment device 300, a main control device 400 and the water tap 100 of any of the above embodiments. The water treatment device 300 is connected to a water path of the faucet 100, and the water treatment device 300 is used for treating water, such as purifying, heating, or foaming, and delivering the treated water to the faucet 100. The main control unit 400 is connected to the opening degree detecting unit 30 and the water treatment device 300 of the faucet 100 to receive sensing information representing the opening degree of the valve cartridge from the opening degree detecting unit 30 and control the water treatment device according to the sensing information.

In one embodiment, as shown in fig. 8, the water treatment machine 200 may be a water purifier 201, and a water treatment apparatus 300 of the water purifier 201 includes a water purification apparatus 301 and a water pump 302. The water purification apparatus 301 is communicated with a water path of the faucet 100, and the water pump 302 is disposed in the water path between the water purification apparatus 301 and the faucet 100.

In the related art, when a mechanical faucet is used in a water purifier, the water outlet of the water purifier is generally controlled by the faucet and a high-pressure switch. When the faucet is closed, the water pump pumps water to increase the pressure in the water channel, when the high pressure value of the high-pressure switch is reached, the high-pressure switch acts, the main control system detects the action information of the high-pressure switch to stop the water pump to work, and when the water pump stops working, the water channel still keeps larger pressure. When the water faucet is opened, the water faucet starts to discharge water, the initial water yield is high, the high-pressure switch acts again when the pressure in the water path is released and reaches the low pressure value of the high-pressure switch, the main control device detects the action information of the high-pressure switch, the water pump is started to work, water discharge is supplemented, and the water purifier system is controlled always according to the mode until the water faucet is closed again, so that the normal water discharge is guaranteed.

However, the process from the beginning of water outlet to the detection of the decrease of the pressure of the waterway to start the water pump to supplement the water outlet is delayed, so that the water outlet fluctuates from large to small and then tends to be stable. The instability of the effluent can greatly affect the use experience of users.

In the water purifier 201 of this embodiment, the opening degree detection device 30 detects magnetic field information representing the current opening degree of the valve element 20, and outputs a hall voltage corresponding to the magnetic field information to the main control device 400, and the main control device 400 converts the hall voltage into the opening degree of the valve element 20 and sends a control signal corresponding to the opening degree to the water pump 302, thereby controlling the operation of the water pump 302. For example, when the faucet 100 is turned off, the main control device 400 obtains the opening degree of the valve element 20 as 0 according to the hall voltage, and the main control device 400 sends a control signal for stopping water supply to the water pump 302, so as to control the water pump 302 to stop water supply. When the faucet 100 is opened, the main control device 400 outputs a corresponding control signal to the water pump 302 according to the opening degree value of the valve cartridge 20 obtained at this time, and the water pump 302 provides water treated by the water purification device 301 to the faucet 100 according to the control signal, and the water supply amount corresponds to the opening degree value of the valve cartridge 20 at this time.

In this embodiment, the water supply amount of the water pump 302 is directly determined by the opening of the valve element 20, rather than the pressure in the water path, so that the water output amount of the faucet 100 can be controlled more immediately, and the situations of delayed reaction of the water pump and short stop of the water output can be avoided. In addition, the display interface of the faucet of the water purifier 201 of the present embodiment can display richer contents, for example, information such as the current valve core opening degree and the current water flow in the water flow passage can be displayed on the display interface of the faucet.

In another embodiment, the main control device 400 may also monitor the time that the valve element 20 is continuously at a certain opening value, and when the time exceeds a preset time, the main control device 400 sends a control signal for stopping water supply to the water pump 302, so as to control the water pump 302 to stop water supply. When the time that the valve core 20 is continuously at a certain opening value exceeds the preset time, it indicates that no one is currently using the faucet 100, and therefore, the main control device 400 automatically controls the water pump 302 to stop supplying water to avoid waste of water.

In one embodiment, the water processor 200 may be a water heater 202, and as shown in fig. 9, the water processing device 300 of the embodiment is a heating device 303, and the heating device 303 is communicated with a water path of the water faucet 100. When a user adjusts the valve core 20 to adjust the water yield of the faucet, the opening detection device 30 detects magnetic field information representing the current opening of the valve core 20 and outputs a hall voltage corresponding to the magnetic field information to the main control device 400, the main control device 400 converts the hall voltage into the opening of the valve core 20 and outputs a control signal to the heating device 303 according to the opening, so as to control the heating power of the heating device 303, and ensure that the water temperature is kept stable after the water yield is changed. In other embodiments, the main control device 400 may also send a control signal to the heating device 303 according to the opening degree of the valve element 20 to adjust the temperature of the water.

In one embodiment, the water treatment apparatus 200 may be a bubbling water machine 203, and as shown in fig. 10, the water treatment apparatus 300 of the present embodiment is an air supply apparatus 304. The air supply 304 is in communication with the water circuit of the faucet 100. When a user adjusts the valve core 20 to adjust the water output of the faucet 100, the opening detection device 30 detects magnetic field information representing the current opening of the valve core 20 and outputs hall voltage corresponding to the magnetic field information to the main control device 400, the main control device 400 converts the hall voltage into the opening of the valve core 20 and outputs a control signal to the air supply device 303 according to the opening, so that the air supply amount of the air supply device 303 is controlled, and the concentration of the soda water is kept stable after the water output of the faucet 100 changes. In other embodiments, the main control device 400 may also send a control signal to the air supply device 304 according to the opening degree of the valve element 20 to adjust the concentration of the soda water.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
