Description

Technical Field

[0001] The present invention relates to the technical field of water outlet devices, and particularly to a transmission structure and a water outlet device. Background Art

[0002] By means of the cooperation of an inclined plane, a rotational motion can be converted into a sliding motion. This structure usually needs to cooperate with an elastic pin to provide a gear feeling for the user. Otherwise, it is difficult for the user to perceive whether the operation on the rotating member has reached the specified position. However, the structure of the elastic pin is relatively complex, and it also occupies a large space in the device, which is not conducive to the miniaturization of the device and the reduction of the manufacturing cost. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned defects or problems in the background art, and provide a transmission positioning structure and a water outlet device. By providing a fixing part and an elastic part on the sliding block, the sliding block of this transmission positioning structure can not only be used as a component that forms an inclined plane cooperation with the rotating part, but also can be used as a component that provides a gear feeling, eliminating the need to install an elastic pin, reducing the complexity of the overall structure.

[0009] In addition, the present invention further provides a water outlet device, which adopts a transmission and positioning structure described in any one of the above; the base is provided with a water outlet part; the water outlet part is provided with a sliding cavity, and a water inlet is provided on the cavity wall of the sliding cavity; the water outlet part is provided with a first water outlet and a second water outlet communicated with the sliding cavity; the sliding member is rotatably stopped and slidably arranged in the sliding cavity, and when it slides to the first position, the water inlet communicates with the first water outlet, and when it slides to the second position, the water inlet communicates with the second water outlet; the rotating member is provided with two positioning grooves corresponding to the first position and the second position.

[0010] Further, a water channel is arranged inside the sliding member, one end of which is communicated with the first water outlet, and a first opening communicating with the water channel is arranged on its side wall; when the sliding member slides to the first position, the water inlet communicates with the first opening.

[0011] Further, a water passing gap is formed by the cooperation of the outer wall of the sliding member and the inner wall of the sliding cavity; a second opening is arranged on the side wall of the sliding cavity; one end of the second opening communicates with the second water outlet, and the other end communicates with the water passing gap; when the sliding member slides to the second position, the water inlet communicates with the water passing gap.

[0012] Further, a plurality of sealing rings are fixedly sleeved on the outer wall of the sliding member along its sliding direction; the first opening is located between the first sealing ring and the second sealing ring among them, and when the sliding member slides to the first position, the water inlet corresponds to the position between the first sealing ring and the second sealing ring; the outer wall of the sliding member between the third sealing ring and the fourth sealing ring forms the water passing gap with the inner wall of the sliding cavity, and when the sliding member slides to the second position, the water inlet corresponds to the position between the third sealing ring and the fourth sealing ring.

[0013] Further, when the sliding member slides to the third position, the water inlet corresponds to the position between the second sealing ring and the third sealing ring to cut off the communication between the water inlet and the first water outlet and the second water outlet.

[0014] Further, at least two sliding blocks are evenly arranged along the circumferential direction of the sliding member; each mating surface on the rotating member for mating with the sliding block is correspondingly arranged for one sliding block.

[0015] Further, a rotating ring groove extending along its circumferential direction is arranged at one end of the water outlet part; the rotating member is provided with a rotating clamping block for clamping with the rotating ring groove.

[0016] Further, when the sliding member slides to the first position, the second position and the third position, it and the corresponding sealing rings are configured to have equal water flow pressures on both sides in its sliding direction.

[0017] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. A rotating member rotatably connected to the base and a sliding member slidably connected to the base for anti-rotation are provided, and the inclined surface matching relationship between the rotating member and the sliding block on the sliding member is utilized. When the rotating member is rotated, the sliding member will slide relative to the base along the extension direction of the rotating shaft, and the sliding block here plays the role of abutting against the rotating member to form an inclined surface matching relationship. At the same time, the sliding block is divided into a fixed part and an elastic part. The elastic part has the characteristics of deforming and restoring deformation relative to the fixed part. At the same time, a positioning groove is provided on the matching surface of the rotating member. When the rotating member slides, the sliding block will slide along the matching surface. When the sliding block reaches the position of the positioning groove, the elastic part will hit the positioning groove. At this time, a gear position sense will be provided to the user, informing the user that the rotation has been in place. The transmission positioning structure combines the dual functions of transmission and positioning on the sliding block, and can provide the user with a gear position sense during control without providing an elastic pin, thereby reducing the overall structural complexity and thus reducing the cost of preparation and assembly.

[0019] 2. A tooth groove with a depth less than that of the positioning groove is provided on the mating surface of the rotating part, and the elastic part can also cooperate with the tooth groove. When the rotating part rotates, the elastic part will enter the positioning groove after passing through the tooth groove. The tooth groove here can improve the user's feel when rotating.

[0020] 3. An annular wall is provided on the rotating part, and an inclined groove is provided on the annular wall. The groove wall on one side of the inclined groove forms the above-mentioned mating surface for realizing the inclined surface mating with the sliding block. At the same time, the sliding block slides along the inclined groove, and the groove wall on the other side relative to the mating surface will support the sliding block, so that the sliding block can move up and down along the extension direction of the rotating shaft, and can also prevent the sliding block from escaping from the range of the mating surface. At the same time, the setting of the inclined groove makes it unnecessary to set a spring for the transmission positioning structure, which not only reduces the complexity of the structure, but also avoids the problem of uneven feel caused by setting a spring.

[0021] 4. The rotating part is composed of a rotating seat and a cover body, which cooperate to form an inclined groove. The sliding part can first pass through the rotating seat and then fix the cover body to the rotating seat. At this time, the sliding block is naturally assembled into the inclined groove. Such a structure can greatly facilitate the installation of the sliding part and the adaptation of the sliding block to the inclined groove, reducing the difficulty of preparation and assembly.

[0022] 5. The base of the water outlet device is provided with a water outlet part for discharging water. A sliding cavity for installing a sliding member is arranged in the water outlet part, and the sliding cavity can introduce water through a water inlet opening. After the water flow enters the sliding cavity, it can be switched to flow to the first water outlet or the second water outlet; the switching of the water outlet device is achieved through the cooperation of a rotating member and the sliding member. The rotating member is installed at one end of the water outlet part. Since it is set at the end position, the rotating member only needs to cooperate with the water outlet part at one end, thereby reducing the installation difficulty of the rotating member and the overall assembly difficulty of the water outlet device; at the same time, the rotating member is in inclined surface cooperation with the sliding member, and the rotation of the rotating member can be converted into the up and down sliding of the sliding member, so that the sliding member can reciprocate between the first position and the second position, switching the connection between the water inlet opening and the first water outlet or the second water outlet, thereby realizing the switching of different water outlet functions of the water outlet device.

[0023] 6. The sliding member is provided with a water passage communicating with the first water outlet. The water inlet opening can be communicated with the water passage through a first opening formed on the side wall of the sliding member. Since the water passage is arranged inside the sliding member, the waterway layout at the water outlet part of the water outlet device is simpler. There is no need to arrange a waterway in the water outlet part to communicate with the first water outlet, and it can be directly communicated through the water passage inside the sliding member.

[0024] 7. The outer wall of the sliding member also cooperates with the inner wall of the sliding cavity to form a water passing gap. At the same time, a second opening is arranged on the side wall of the sliding cavity. Through the water passing gap and the second opening, the water inlet opening can be communicated with the second water outlet. Since the water passing gap is formed by the cooperation of the outer wall of the sliding member and the inner wall of the sliding cavity, there is no need to arrange a separate waterway on the body of the water outlet device at the water outlet part, so it also has the effect of reducing the complexity of the body waterway layout.

[0025] 8. A plurality of sealing rings are sleeved on the sliding member. By using the sealing effect of the sealing rings, the water inlet opening can be separately corresponding to the positions of the first opening and the water passing gap respectively, so as to achieve the purpose of switching the water outlet function.

[0026] 9. The sliding member can also slide to a third position between the first position and the second position. When sliding to the third position, the water flow of the water inlet opening is blocked by the second sealing ring and the third sealing ring, so that the water discharge of the water outlet device is closed.

[0027] 10. At least two sliding blocks and the mating surfaces cooperating with the sliding member are uniformly arranged relative to the rotating shaft, so that the force relationship between the rotating member and the sliding blocks is in a uniform and symmetrical state, thereby reducing the probability of damage or detachment of the rotating member. At the same time, since the water passage on the sliding member is arranged inside the sliding member, the waterway does not have to be arranged in the body of the water outlet device, thus providing space for the sliding member to be centered relative to the rotating member.

[0028] 11. A rotating ring groove is provided on the water outlet part, and a rotating clamping block that can be clamped in the rotating ring groove and slide along the rotating ring groove is provided on the rotating part, so that the rotating part can rotate relative to the water outlet part while realizing axial limit relative to the water outlet part.

[0029] 12. When the sliding part slides to the first, second, and third positions, the water flow pressures received on both sides in the sliding direction cancel each other out, so that the sliding of the sliding part can avoid the influence of the water flow pressure, making the user's operation feel more comfortable.

[0048] See Figure 1 , Figure 1 shows an exploded view of the structure of the first embodiment of a water outlet device provided by the present invention. A transmission and positioning structure is adopted in the water outlet device, and the specific content of the transmission and positioning structure will be explained together in the description of the water outlet device. The water outlet device in this first embodiment mainly includes a base, a rotating member, a sliding member 30 and several sealing rings.

[0049] Refer to Figure 1 , the base can be divided into a hand-held part and a water outlet part. The hand-held part is used for the user to hold, and the water outlet part is used to form water outlet. Specifically, the base is composed of a body 10, a water inlet joint 11, a fixed seat 12, a bubbler 13 and a water outlet member 14.

[0050] Among them, the body 10 includes a first tubular member 101 and a second tubular member 102 integrally formed. The first tubular member 101 extends along a first direction, and is mainly used to form the above-mentioned hand-held part. At the same time, refer to Figures 6 to 8 , a water inlet channel 104 is provided inside the first tubular member 101. The water inlet joint 11 is fixedly connected to one end of the first tubular member 101 and is used to connect with an external water inlet pipe to introduce external water into the water inlet channel 104. The second tubular member 102 extends along a second direction perpendicular to the first direction and forms the main part of the water outlet part. A chamber that penetrates up and down along the second direction is provided inside the second tubular member 102. A water passing port 105 is provided on the side wall of the chamber. The water passing port 105 communicates with the water inlet channel 104 in the first tubular member and is used to introduce water into the chamber. A plurality of upwardly extending anti-rotation protrusions 103 are also provided at the upper end position of the second tubular member 102, and a region between the anti-rotation protrusions 103 forms an anti-rotation sliding groove extending along the second direction.

[0051] The fixed seat 12 is an annular member, which is fixedly connected to the upper opening of the second tubular member 102 by a snap - fixing method, and a rotating ring groove extending along its circumferential direction is provided on its outer side wall. When it is installed on the second tubular member 102, it surrounds the above - mentioned anti - rotation projection 103.

[0052] Referring to Figures 6 to 8 , the water outlet member 14 is screwed and fixed to the lower opening of the second tubular member 102, and a cylindrical structure penetrating up and down is provided in the middle position thereof. The upper end of the cylindrical structure abuts against the bottom end of a downward - extending flange on the inner wall surface of the second tubular member 102 to form a limit, and a plurality of second openings 141 are provided on its upper end surface. At the same time, a communication water channel 143 is formed by the cooperation between the outer wall surface of the cylindrical structure and the inner wall surface of the second tubular member 102. The second openings 141 communicate the inside of the cylindrical structure with the communication water channel 143. An installation cavity for installing the bubbler 13 is formed at the lower end of the cylindrical structure. The water outlet of the bubbler 13 forms the first water outlet 142 of the water outlet part. When water flows through the bubbler 13, bubble water will be formed. At the same time, the first water outlet 142 communicates with the inner cavity of the above - mentioned cylindrical structure. The inner cavity of the cylindrical structure and the inner cavity of the second tubular member 102 jointly form a sliding cavity for the sliding member 30 to slide. A water outlet channel is further provided in a circle on the outer ring of the water outlet member 14. The water outlet of the water outlet channel forms the second water outlet 144 of the water outlet part. The second water outlet 144 communicates with the communication water channel 143, and in the first embodiment, the second water outlet 144 is designed as a structure with a gradually decreasing water - passing area, so that the water flow will form spray gun water after passing through the second water outlet 144.

[0053] The above - mentioned second tubular member 102, fixed seat 12, bubbler 13 and water outlet member 14 jointly constitute the water outlet part of the base.

[0054] Referring to Figure 2 and Figure 3 , the rotating member includes a rotating seat 21 and a cover body 22 fixedly connected to the rotating seat 21, and the rotating member is rotationally connected to the base around a rotating shaft.

[0055] Specifically, referring to Figure 2, the rotating seat 21 is provided with a main body part and a handle 211 integrally formed with the main body part. The handle 211 is used for the user to toggle and thus control the rotation of the rotating member relative to the base. A circular through-hole extending along the extension direction of the rotation axis of the rotating member is provided in the main body part of the rotating seat 21. The circular through-hole is formed by a lower ring wall 216. On the wall surface of the lower ring wall 216, two inclined surfaces 215 are evenly arranged circumferentially. The two inclined surfaces 215 are inclined relative to the rotation axis of the rotating member and are arranged in a spiral shape along the wall surface of the lower ring wall 216. The inclination angles of the two inclined surfaces 215 are opposite. In the area between the two inclined surfaces 215, the lower ring wall 216 is further provided with two symmetric second card slots 214. The second card slots 214 extend along the extension direction of the rotation axis and are used to form a fixed connection and cooperation relationship with the cover body 22. At a corresponding end position of the two inclined surfaces 215, a limiting part 217 is further provided. A blocking surface perpendicular to the rotation axis is formed on the limiting part 217. At the same time, the limiting part 217 is also used to form a side wall of the second card slot 214. In addition, four first card slots 213 are circumferentially arranged on the part of the main body part of the rotating seat 21 outside the lower ring wall 216. The four first card slots 213 are used to form a fixed connection and cooperation relationship with the cover body 22. At the position between the first card slots 213, the rotating seat 21 is further provided with a rotating block 212. The rotating block 212 can cooperate with the rotating ring groove on the fixed seat 12, so that the rotating seat 21 can be rotatably connected with the fixed seat 12 with axial limit.

[0056] Referring to Figure 3 , the cover body 22 includes a substrate. Four first card heads 224 are arranged at the outer peripheral position of the substrate. The four first card heads 224 can be clamped into the first card slots 213 on the rotating seat 21, so as to fix the cover body 22 to the rotating seat 21. Two upper ring walls 221 are evenly protruded at the middle position of the substrate. The positions of the two upper ring walls 221 correspond to the positions of the two inclined surfaces 215 on the lower ring wall 216 of the rotating seat 21. And a mating surface 222 inclined relative to the rotation axis is formed on the surface of the two upper ring walls 221 facing the rotating seat 21. Referring to Figure 5 , when the cover body 22 is fixed to the rotating seat 21, the mating surface 222 can cooperate with the inclined surface 215 to form two inclined grooves 23 with opposite inclined directions. Three positioning grooves 223 are further provided on the mating surface 222. The positioning grooves 223 are recessed downward relative to the surface of the mating surface 222.

[0057] On the cover body 22, two symmetric second card heads 225 are further protruded at the position between the two upper ring walls 221. The second card heads 225 can be clamped into the second card slots 214 on the rotating seat 21, so as to form another limiting structure at the other end of the inclined groove relative to the limiting part 217.

[0058] Referring to Figure 4, the sliding member 30 includes a sliding rod as the main body and an anti-rotation slider 33 and a sliding block 34 provided at the upper end of the sliding rod. Along the extension direction of the outer wall of the sliding rod, a first sealing ring groove 311, a second sealing ring groove 312, a third sealing ring groove 313, and a fourth sealing ring groove 314 are sequentially provided, which are respectively used for installing and sleeving a first sealing ring 41, a second sealing ring 42, a third sealing ring 43, and a fourth sealing ring 44. A first water diversion part 321 is formed between the first sealing ring groove 311 and the second sealing ring groove 312, a second water diversion part 322 is formed between the second sealing ring groove 312 and the third sealing ring groove 313, and a third water diversion part 323 is formed between the third sealing ring groove 313 and the fourth sealing ring groove 314. Wherein, the sliding rod is provided with a first opening 3211 at the first water diversion part 321.

[0059] Two sliding blocks 34 for cooperating with the inclined grooves 23 are provided at the upper end position of the sliding rod. These two sliding blocks 34 can be respectively inserted into the two inclined grooves 23 and slide along the extension direction of the inclined grooves 23. The sliding blocks 34 are specifically provided on two anti-rotation sliders 33 protruding from the outer wall surface of the sliding rod. These two anti-rotation sliders 33 can cooperate with the anti-rotation chute formed by the anti-rotation protrusions 103 when the sliding member 30 is inserted into the sliding cavity, so that the sliding member 30 slides relative to the base in a non-rotating manner in the sliding cavity.

[0060] In addition, the sliding block 34 includes a fixed portion and an elastic portion adapted to abut and cooperate with the positioning groove 223. The fixed portion is the part where the sliding block 34 is connected to the anti-rotation slider 33, and this part cannot deform because it is connected to the anti-rotation slider 33. The elastic portion is the part of the sliding block 34 that is separated from the anti-rotation slider 33. Since the elastic portion is not connected to the anti-rotation slider 33, it can have a certain deformation ability relative to the fixed portion and will exhibit elastic deformation when it is pressed. Moreover, the deformation direction of the elastic portion is consistent with the extension direction of the rotation axis. This makes it so that when the sliding block 34 is installed in the inclined groove 23, the elastic portion will be pressed by the mating surface 222 to deform. When the sliding block 34 reaches the position of the positioning groove 223, the elastic portion will fall into the positioning groove 223, thereby forming a gear feeling. Further, a positioning protrusion 341 is provided on the elastic portion. The positioning protrusion 341 can fall into the positioning groove 223 and is provided with a smooth transition surface that matches the shape of the positioning groove 223, which can ensure that the elastic portion can disengage from the state of cooperating with the positioning groove 223 and enter the next positioning groove 223. At the same time, the positioning protrusion 341 can also serve to reduce the contact area between the sliding block 34 and the mating surface 222, thereby reducing the frictional resistance between the sliding block 34 and the mating surface and making it more convenient to control the up and down sliding of the slider 30. It should be noted that on the lower surface of the sliding block 34, that is, on the side facing the inclined surface 215, a protrusion structure is provided corresponding to the position of the fixed portion. This protrusion structure enables the thickness of the fixed portion to match the width of the inclined groove 23 and causes the protrusion structure to abut against the inclined surface 215. At the same time, it provides a relief space for the deformation of the elastic portion to prevent the elastic portion from being limited by the inclined surface 215 and resulting in too small a degree of deformation.

[0061] Referring to Figures 6 to 8 , an aqueduct 3212 is also provided inside the slider 30. The upper end of the aqueduct 3212 communicates with the first opening 3211, and its lower end forms an outlet on the lower end surface of the slide bar. And this outlet will cooperate with the inner cavity of the water outlet member 14 to connect the aqueduct 3212 to the first water outlet 142.

[0062] When the slider 30 is slidably disposed in the sliding cavity in a non-rotating manner, the sealing ring sleeved on the sliding cavity will adhere to the cavity wall of the sliding cavity, thereby isolating each water distribution portion from each other. At the same time, the sealing ring can also position the slider 30 at the corresponding position without moving when it is not driven by the rotating member through the frictional resistance between it and the cavity wall of the sliding cavity. This is also because the pressure-bearing areas of each sealing ring groove and the corresponding sealing ring on the slider 30 are equal when the water passes through the water outlet device, which makes the water flow pressures on both sides of the slider 30 in the sliding direction equal, thereby avoiding the influence of the water flow pressure on the operation feel and the positioning of the slider 30.

[0063] In this embodiment, the slider 30 needs to first pass through the circular through-hole on the rotating seat 21 and be inserted into the sliding cavity, and then the cover 22 is fixedly connected to the rotating seat 21, so that the slider 34 can enter the inclined slot 23. When the rotating member rotates, the inclined slot 23 drives the slider 30 to slide up and down along the extension direction of the rotating shaft through the cooperation relationship with the inclined surface of the slider 34.

[0064] Referring to Figures 6 to 8 , the following describes the specific usage process of the water outlet device in this embodiment.

[0065] The above-mentioned slider 30 can reciprocate between the first position, the second position and the third position under the action of the rotating member. The first position is the position where the slider 30 moves to the bottommost end, the second position is the position where the slider 30 moves to the topmost end, and the third position is the position between the first position and the second position. The bottommost end and the topmost end here are defined with respect to the water outlet end of the water outlet part as the lower side. In this embodiment, the positioning of the slider 30 is achieved by the friction force between the sealing ring sleeved on it and the wall of the sliding cavity. At the same time, it is determined whether the slider 30 reaches the first position, the second position and the third position by whether the elastic part abuts against the corresponding positioning groove 223. Therefore, three positioning grooves 223 are correspondingly provided, and the positions of each positioning groove 223 respectively correspond to the first position, the second position and the third position.

[0066] Taking the slider 30 moving to the first position as the initial position, at this time the slider 34 is located at the bottommost end of the inclined slot 23, and the slider 34 is limited by the second locking block 225, so that the slider 34 cannot move any further. At this time, the slider 30 cannot move any further either, and the bottom end of the slider 30 will also abut against the water outlet member 14, thereby limiting the limit position of the bottommost end of the slider 30 and also limiting the limit position of the rotating member rotating in this direction; at the same time, at this first position, the first water dividing part 321 on the slider 30 is directly opposite to the water passing port 105, and the water flow can pass through the water passing port 105, the first water dividing part 321 and the first opening 3211 and enter the water passing channel 3212, and then enter the first water outlet 142 of the water outlet member 14 from the water passing channel 3212 to form water outlet.

[0067] Rotate the rotating member to make the slider 30 reach the third position. At this position, the second water dividing part 322 on the slider 30 is directly opposite to the water passing port 105, and the water flow passing through the water passing port 105 will be blocked by the second sealing ring 42 and the third sealing ring 43, thereby cutting off the connection with the first water outlet 142 and the second water outlet 144.

[0068] Continue to rotate the rotating member to move the sliding member 30 to the second position. At this time, the sliding block 34 will abut against the limiting portion 217, and the rotating member cannot continue to rotate, nor can the sliding member 30 move upward any further. At this position, the third water dividing portion 323 on the sliding member 30 is aligned with the water passing port 105. The water passing gap 35 formed by the cooperation between the outer wall of the sliding member 30 at the third water dividing portion 323 and the inner wall of the sliding cavity communicates with the water passing port 105. Water can enter the communicating water channel 143 through the water passing port 105, the water passing gap 35, and the second opening 141, and then reach the second water outlet 144 to form water output. Then, rotate the rotating member in the other direction, and the sliding member 30 will return to the third position and the first position in sequence.

[0069] In addition, since the rotating member is installed at the upper end position of the water outlet portion, and the handle 211 of the rotating seat 21 faces the position where the handheld portion is located, when the user holds the handheld portion of the water outlet device, the user can still operate the handle 211 with one hand, making the switching operation of the water output function of the water outlet device very convenient.

[0070] In addition, the present invention also provides Embodiment 2. The difference between Embodiment 2 and Embodiment 1 is that a tooth groove 226 is further provided on the mating surface 222, and a tooth groove protrusion 342 adapted to the tooth groove 226 is provided on the positioning protrusion 341.

[0071] Specifically, referring to Figure 9 and Figure 10 , a plurality of continuous tooth grooves 226 are provided at the position between the three positioning grooves 223 on the mating surface 222. The depth of the tooth groove 226 is lower than the depth of the positioning groove 223, and the width of the tooth groove 226 is also lower than the width of the positioning groove 223, that is, the size of the tooth groove 226 is smaller than the size of the positioning groove 223.

[0072] On the positioning protrusion 341 of the sliding block 34, a tooth groove protrusion 342 with a size adapted to the tooth groove 226 is further protrudingly provided, and the tooth groove protrusion 342 can abut against the tooth groove 226.

[0073] When the rotating member rotates, the tooth groove protrusion 342 will sequentially fall into the tooth groove 226, providing a better rotation feel for the user.

[0074] The present invention provides a transmission positioning structure and a water outlet device. By providing a fixing portion and an elastic portion on the sliding block 34, the sliding block 34 can not only be used as a component for forming an inclined surface fit with the rotating member, but also be used as a component for providing a gear feeling, eliminating the need to install an elastic pin, reducing the complexity of the overall structure. The water outlet device adopting this transmission positioning structure has a simpler structure and also reduces the manufacturing and maintenance costs.

[0075] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation to the protection scope of the present invention. Through the inspiration of the present invention or the above embodiments, those of ordinary skill in the art, combining well-known common sense, general technical knowledge in the field and / or the prior art, can obtain modifications, equivalent replacements or other improvements to the embodiments of the present invention or some of its technical features through logical analysis, reasoning or limited experiments, and all of them should be included within the protection scope of the present invention.
