[0002] In the prior art, in order to provide a richer range of water discharge patterns and a better massage experience, a massage water outlet device usually sets a rotating mechanism to form a rotating water splash. However, the rotating water splash is often affected by the centrifugal force of the rotating mechanism and flies to the periphery. The angle of the water spray cannot be controlled, the water splash is seriously wasted, not full enough, and the impact effect on the human body is not good, so it cannot provide users with a satisfactory massage experience. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned defects or problems existing in the background technology, and to provide a water outlet device, which can enhance the initial water outlet velocity of the rotating water splash along the direction of the rotation axis, reduce the opening angle of the water splash and enhance the anti-splashing effect of the rotating water splash, so that the user can get a satisfactory massage and flushing experience.

[0004] In order to achieve the above objectives, the following technical solutions are adopted:

[0005] A water outlet device comprises: a main body provided with a water outlet hole; a rotating member which rotates relative to the axis of the water outlet hole and is provided with a protrusion extending into the water outlet hole; an outer peripheral wall of the protrusion and the hole wall of the water outlet hole form a water outlet gap; the spacing of the water outlet gap decreases along the water outlet direction.

[0006] Furthermore, a water outlet groove is provided on the side wall of the protruding portion; the width of the water outlet groove decreases along the water outlet direction and the bottom end thereof is open.

[0007] Furthermore, the main body is further provided with a water outlet cavity; the water outlet cavity guides water to flow toward the water outlet gap through a water passage; the water passage is formed by the main body or formed by the cooperation of the main body and the rotating member.

[0008] Furthermore, the water outlet direction of the water passage is inclined relative to the axial direction and radial direction of the rotating member, and the tangential component of the inclined direction is opposite to the rotation direction of the rotating member.

[0009] Furthermore, the water outlet direction of the water outlet trough is inclined relative to the axial direction of the rotating member, and the inclination direction is opposite to the rotation direction of the rotating member.

[0010] Furthermore, the rotating member is also provided with a rotating portion connected to the protrusion as a whole; the rotating portion is located in the water outlet cavity; the main body is also provided with an inclined water channel connected to the water outlet cavity; the inclined water channel points to the rotating portion and guides the water flow to drive the rotating portion to rotate.

[0011] Furthermore, the main body is also provided with a water inlet and a water hole; the water inlet is connected to the inclined water channel; the water hole is connected to the water inlet and the water outlet cavity, and its direction parallel to the axial direction of the rotating part points to the rotating part.

[0012] Furthermore, the main body is provided with an annular wall; one end of the annular wall protrudes into the water outlet cavity, and its central hole constitutes the water outlet hole; the annular wall is located on the end face of the water outlet cavity and is provided with a water flow groove that is radially inclined relative to the water outlet hole; the side wall of the protrusion is provided with a vertical axial abutment surface; the abutment surface overlaps the end face of the annular wall and defines the water flow channel with the water flow groove.

[0013] Furthermore, the rotating member is provided with a water outlet channel running through the rotating member along its axial direction; the water outlet channel is connected to the water outlet cavity and has at least one water outlet.

[0014] Furthermore, the water outlet direction of the water passage is inclined relative to the axial direction and radial direction of the rotating member, and the tangential component of the inclined direction is the same as the rotation direction of the rotating member.

[0015] Compared with the prior art, the above solution has the following beneficial effects:

[0016] 1. The water outlet device provided in the present application has a rotating part that can rotate relative to the main body and its outer peripheral wall and the water outlet hole define a water outlet gap. The water flow in the water outlet gap can rotate with the rotating part and finally realize a rotating water outlet curtain, which has a good massage effect. In the water outlet device, since the spacing of the water outlet gap decreases along the water outlet direction, the water flow in the water outlet gap has a larger initial water outlet velocity along the water outlet direction, and the pressurization effect is obvious. When the centrifugal force of the rotating part remains unchanged, it is beneficial to reduce the angle of the rotating water outlet curtain relative to the water outlet direction and reduce the phenomenon of flying toward the periphery, so that the water flow of the rotating water outlet curtain is more concentrated and full, and the flushing effect and massage effect on the user are also better.

[0017] 2. The water outlet device provided in the present application has a water outlet groove provided on the side wall of the protruding portion, so that the water outlet gap can form a relatively thick water curtain portion at the water outlet groove. The flushing force of this water curtain portion on the human body is greater than the flushing force of the water curtain portion corresponding to the water outlet groove without forming a water outlet groove, thereby providing the user with a pulse-like massage experience when the water outlet curtain rotates. Because the width of the water outlet groove decreases along the water outlet direction and the bottom end is open, the water outlet flow corresponding to the water outlet groove also has a large initial water outlet velocity and a supercharging effect, thereby further enhancing the anti-splashing ability of the rotating water outlet curtain, so that the water flow of the rotating water outlet curtain has a concentrated and full shape and a good flushing and massage effect.

[0018] 3. The water outlet device provided in the present application is connected to the water outlet gap and the water outlet chamber through a water flow channel. The water flow area of ​​the water flow channel is small. When the water flow in the water outlet chamber enters the water flow channel, its water flow speed will inevitably accelerate, and the flow rate of the water flow in the water outlet gap will be enhanced again. The initial water outlet velocity of the water flow in the water outlet gap along the water outlet direction is also enhanced, thereby further offsetting the influence of centrifugal force on the rotating water outlet curtain, and enhancing the anti-splashing ability, flushing effect and massage effect of the rotating water outlet curtain.

[0019] 4. The water outlet device provided in the present application has a water outlet direction of the water channel that is inclined relative to the axial and radial directions of the rotating part, and the tangential component of the inclined direction is opposite to the rotation direction of the rotating part. Therefore, the water flow guided by the water channel can exert a thrust on the rotating part in the opposite direction of its rotation when it hits the rotating part, thereby reducing the rotation speed of the rotating part and reducing the centrifugal force on the rotating water outlet curtain. This is beneficial to reducing the angle of the rotating water outlet curtain relative to the water outlet direction and the phenomenon of flying toward the periphery, and further improving the fullness of the rotating water outlet curtain and the flushing and massage effects on the user.

[0020] 5. In the water outlet device provided in the present application, the water outlet direction of the water outlet trough is inclined relative to the axial direction of the rotating part and the inclination direction is opposite to the rotation direction of the rotating part, that is, the water outlet direction of the water outlet trough is opposite to the direction of centrifugal force, which further reduces the impact of the centrifugal force and the inertia of the rotating water outlet curtain thrown out along the rotation direction under the action of centrifugal force, thereby further reducing the angle of the rotating water outlet curtain relative to the water outlet direction and the phenomenon of flying toward the periphery.

[0021] 6. In the water outlet device provided in the present application, the rotating parts are rotated by the impact of the water flow guided by the inclined water channel, and the rotation is achieved by using hydraulic force, with little energy waste, simple structure and reliable rotation function.

[0022] 7. The water outlet device provided in the present application has a water hole provided on the main body, which can guide the water flow to the impact rotating part and apply rotational resistance to further reduce the rotation speed of the rotating part and the influence of the centrifugal force on the rotating water outlet curtain.

[0023] 8. The water outlet device provided in the present application stipulates that the main body is provided with an annular wall, and one end of the annular wall protruding into the water outlet chamber can be overlapped by the rotating part of the rotating part, thereby avoiding the abutment surface from completely abutting against the inner cavity wall of the water outlet chamber, reducing the friction between the rotating part and the inner cavity wall of the water outlet chamber, and ensuring that the rotating part can rotate smoothly; in addition, the setting of the annular wall also makes it easy to form a water passage, and the structure is less difficult to form.

[0024] 9. The water outlet device provided in the present application has a rotating part provided with a water outlet channel, and a part of the water flow in the water outlet cavity can flow out from the water outlet channel. Since the water outlet channel is located on the inner side of the water outlet gap, the water outlet device has the water outlet effects of internal rotating water splashes and external rotating water curtains, and the water outlet distribution volume increases geometrically compared to the distribution volume of non-rotating water outlet. The water outlet is delicate, the massage effect is good, and the user experience is good. At the same time, under the covering of the rotating water curtain on the outer ring, the water splashes from the water outlet channel cannot splash out, so the overall water outlet still has a good anti-splashing effect; the water outlet channel has at least one water outlet, which can meet the needs of achieving different water outlet effects.

[0025] 10. The water outlet device provided in the present application has a water outlet direction of the water channel that is inclined relative to the axial and radial directions of the rotating part, and the tangential component of the inclined direction is the same as the rotation direction of the rotating part. Therefore, the water flow guided by the water channel can exert a thrust on the rotating part in the same direction of rotation when it hits the rotating part. When the rotating water curtain has a large initial water outlet velocity along the water outlet direction, the rotation speed of the rotating part is improved to a certain extent, which is conducive to making the outlet water particles finer and meeting the flushing needs of some specific scenarios.

[0054] The technical solutions in the embodiments will be described clearly and completely below with reference to the accompanying drawings.

[0055] See also Figures 1 to 16 , Figures 1 to 16 The water outlet device of this embodiment is shown in FIG. Figures 1 to 16 As shown, the water outlet device in this embodiment includes a body 1, a rotating member 2, a first sealing ring 3 and a second sealing ring 4.

[0056] The main body 1 is provided with a water outlet. Specifically, in this embodiment, the main body 1 includes a shell 11 , a base 12 and a sealing cover 13 .

[0057] like Figure 1 and Figure 2 As shown, the shell 11 is a tubular structure with a stepped hole provided therein, wherein the small hole of the stepped hole constitutes a water inlet 111; the large hole of the stepped hole constitutes an installation cavity 112, and the inner wall of the installation cavity 112 is provided with an internal thread.

[0058] like Figures 1 to 3 and Figure 9 As shown, the base 12 includes a base body 121 and an annular wall 122 .

[0059] The seat body 121 is cylindrical, and its outer wall is provided with an external thread, an inclined water channel 1211 and an annular limiting groove 1214. The portion of its inner wall near its open end is provided with a step surface 1212 perpendicular to its axis, and its open end is provided with a plurality of spaced buckles 1213 extending along the axis; wherein the external thread is used to be screwed with the internal thread of the inner wall of the shell 11. When screwed, the open end of the seat body 121 faces the shoulder 110 of the step hole of the shell 11, and the inclined water channel 1211 is perpendicular to the seat body. The body 121 is along the axis of the seat body 121 and is radially inclined relative to the seat body 121; the annular limiting groove 1214 is used for the installation of the first sealing ring 3. When the seat body 121 and the shell 11 are screwed into place, the first sealing ring 3 is sealed and abutted against the inner wall of the installation cavity 112 and the groove wall of the annular limiting groove 1214 to realize the sealing relationship between the base 12 and the shell 11 to avoid water leakage in the installation cavity 112; the step surface 1212 is used for the abutment of the second sealing ring 4; the buckle 1213 is used to snap into connection with the sealing cover 13.

[0060] The annular wall 122 coaxially passes through and is integrally formed on the bottom of the seat body 121, one end of which protrudes into the inner cavity of the seat body 121, and the other end protrudes out of the outer wall of the bottom of the seat body 121, and the center hole thereof constitutes the water outlet of the body 1; the annular wall 122 is located on the end surface of one end of the inner cavity of the seat body 121 and is provided with a water groove 1221, and both ends of the water groove 1221 pass through the annular wall 122, that is, the two ends of the water groove 1221 are respectively connected to the inner cavity of the seat body 121 and the water outlet.

[0061] like Figures 1 to 3As shown, the sealing cover 13 is suitable for sealingly covering the open end of the seat body 121. Specifically, the sealing cover 13 is a circular plate-shaped structure, and its side wall is provided with an annular flange 131. A plurality of spaced ribs 133 are provided on one side surface near the periphery. In addition, at least one water hole 134 is provided thereon which passes through in the axial direction; wherein, the annular flange 131 is circumferentially provided with a plurality of slots 132 spaced apart in the circumferential direction. When the sealing cover 13 and the seat body 121 are covered, part of the sealing cover 13 is matched and embedded in the inner cavity of the seat body 121, and the annular flange 131 abuts against the end face of the open end of the seat body 121, and each buckle 1213 is respectively axially engaged with each slot 132 to limit the sealing cover 13 from being separated from the seat body 121; the second sealing ring 4 is sleeved on the outer periphery of the sealing cover 13 and Abutting against the step surface 1212, when the sealing cover 13 and the seat body 121 are snapped into place, the sealing cover 13 and the inner cavity of the seat body 121 define a water outlet chamber 10. The annular flange 131 cooperates with the step surface 1212 to press against the second sealing ring 4 to prevent water leakage from the water outlet chamber 10. It is understandable that the sealing cover 13 in this embodiment can also be stably fixed to the base 12 by bonding or welding. The snap-fit ​​method is only an example provided in this embodiment. The rib 133 is used to abut against the shoulder 110 of the step hole of the shell 11 to ensure that the surface of the sealing cover 13 and the inner wall of the step hole define a water flow gap, so that water flowing in from the water inlet 111 can flow through this water flow gap and the gap between the side wall of the seat body 121 and the inner wall of the shell 11 to the inclined water channel 1211 and the water outlet chamber 10. Since the water flow hole 134 passes through the sealing cover 13, the water flow hole 134 connects the water inlet 111 and the water outlet chamber 10.

[0062] The rotating member 2 is mounted on the body 1 and is adapted to rotate relative to the axis of the water outlet. Specifically, Figure 3 and Figure 4As shown, the rotating member 2 includes a protruding portion 21 and a rotating portion 22 connected as one body; the protruding portion 21 includes a protruding shaft 211, a plurality of protrusions 212 and an annular abutting flange 213; the protruding shaft 211 is a cylindrical component, which partially extends into the water outlet and is coaxial with the water outlet; the protrusions 212 are arc-shaped sheet structures, each protrusion 212 is protruded from the side wall of the protruding shaft 211 and is evenly spaced along the circumferential direction, each protrusion 212 is located in the water outlet and the intervals between each protrusion 212 form a water outlet groove 210, and at the same time, the outer wall of each protrusion 212 (that is, the outer peripheral wall of the protruding portion 21) and the hole wall of the water outlet form a water outlet gap 100; the abutting flange 213 is coaxially formed on the protruding shaft 211 The outer wall has an outer diameter greater than the aperture of the water outlet, and one end of each protrusion 212 extends to be connected with one side end face of the abutting flange 213, and the abutting flange 213 connects the side end face of each protrusion 212 to form an abutting surface 2131, and the abutting surface 2131 is perpendicular to the axial direction. When the part of the convex shaft 211 with the protrusion 212 extends into the water outlet, the abutting surface 2131 of the abutting flange 213 overlaps the end face of the annular wall 122 and defines a water passage 200 with the water groove 1221, thereby avoiding the abutting surface 2131 from completely abutting with the inner cavity wall of the water outlet chamber 10, reducing the friction between the rotating part 2 and the inner cavity wall of the water outlet chamber 10, and ensuring that the rotating part 2 can rotate smoothly.

[0063] As can be seen from the above structure, the water passage 200 connects the water outlet cavity 10 and the water outlet gap 100, and the water outlet groove 210 opens at one end away from the abutment surface 2131. It should be understood that the water passage 200 can also be independently formed on the annular wall 122, without being formed by the abutment surface 2131 and the water passage groove 1221. In other words, the water passage 200 can be formed by the main body 1 or by the main body 1 and the rotating member 2. This embodiment is provided as an example only.

[0064] The rotating portion 22 is integrally formed with the protruding portion 21 and includes a plurality of blades 221. Each blade 221 is arranged at intervals along the circumferential direction and is fixed to one end of the protruding portion 21 away from the abutting surface 2131, thereby forming an impeller structure. The impeller structure is coaxial with the protruding portion 21, is located in the water outlet chamber 10, and its top end is abutted against the inner surface of the sealing cover 13, that is, in this embodiment, the inner surface of the sealing cover 13 limits the axial displacement of the rotating part 2 by cooperating with the end face of the annular wall 122; the inclined water channel 1211 points to the rotating portion 22 and can guide the water flow to drive the rotating portion 22 to rotate, so as to realize the rotation function of the rotating part 2. It should be understood that the rotation of the rotating part 2 relative to the main body 1 can also be achieved by electric drive. This embodiment is only an example, which adopts a hydraulically driven rotation method with low energy consumption, simple structure and reliable rotation function.

[0065] In this embodiment, a water outlet channel 23 is coaxially provided in the protrusion 21 and extends through the axial direction. The water outlet channel 23 is connected to the water outlet cavity 10 and has at least one water outlet 231. Specifically, the water outlet 231 can be as follows: Figure 10 The spindle shape shown can also be Figure 11 The plurality of column holes shown are at different distances from the axis of the protrusion 21, or a plurality of fan-blade holes arranged circumferentially or a plurality of straight-line holes extending radially, wherein the spindle-shaped water outlet hole can form a blade-shaped water outlet; the column holes can be located in the same radial direction or distributed in different radial directions, which can form a water curtain-shaped water outlet; the fan-blade holes or the straight-line holes can form a water curtain-shaped water outlet with a certain thickness. It is worth noting that since the rotating member 2 rotates when the water is discharged, see Figure 12 and Figure 13 as well as Figure 14 and Figure 15 The effect comparison diagram shows that the water distribution volume of the water outlet channel 23 increases geometrically compared with the non-rotating water distribution volume. The water outlet is delicate, the massage effect is good, and the user experience is good.

[0066] It can be seen from the above structure that in the water outlet device, the water flowing in from the water inlet 111 can flow into the inclined water channel 1211 and the water outlet cavity 10 through the water gap and the gap between the side wall of the seat body 121 and the inner wall of the shell 11, and then flow into the water outlet gap 100 from the water passage 200. The water outlet gap 100 can form an annular water curtain-shaped water outlet. Since the rotating part 2 can rotate under the drive of the water flow, the water outlet gap 100 forms a rotating water curtain-shaped water outlet, which has a good massage effect. However, in actual use, the rotating water outlet water curtain is easily affected by centrifugal force and splashes to the periphery. In order to solve this problem, this embodiment adopts the following method to solve it.

[0067] like Figure 3 As shown, the water outlet is a conical hole, the large end of which is located on one side of the water outlet cavity 10, and the small end is used for water outlet, thereby reducing the spacing of the water outlet gap 100 along the water outlet direction. This structure enables the water flow in the water outlet gap 100 to have a larger initial velocity along the water outlet direction, and the supercharging effect is obvious. Therefore, when the centrifugal force of the rotating part 2 remains unchanged, it is beneficial to reduce the angle of the rotating water outlet curtain relative to the water outlet direction and weaken the tendency of the rotating water outlet curtain to fly outward, thereby making the water flow of the rotating water outlet curtain more concentrated and full, and the flushing effect and massage effect on the user are also better. It should be understood that the reduction of the water outlet gap 100 can also be achieved by providing the side wall of the rotating part 2 with a conical surface. This embodiment is only an example.

[0068] Better, if Figure 4As shown, in this embodiment, the width of the water outlet trough 210 also decreases along the water outlet direction. First, the arrangement of the water outlet trough 210 enables the water outlet gap 100 to form a relatively thick water curtain portion at the water outlet trough 210. This thicker water curtain can provide a relatively large flushing force to the user. During the rotation of the rotating member 2, the thicker water curtain portion can change position as the position of the water outlet trough 210 changes, giving the user a pulse-like massage experience. In addition, since the width of the water outlet trough 210 decreases along the water outlet direction, the water flow corresponding to the water outlet trough 210 also has a large initial water velocity and a pressurizing effect, thereby further enhancing the anti-splashing ability of the rotating water outlet curtain and achieving the purpose of further improving the fullness, flushing effect, and massage effect of the rotating water outlet curtain.

[0069] In addition, since the water outlet gap 100 is connected to the water outlet chamber 10 through the water flow channel 200, the water flow area of ​​the water flow channel 200 is small. When the water flows from the water outlet chamber 10 into the water flow channel 200, the water flow area is reduced, which inevitably accelerates the water flow speed, thereby making the water flow entering the water outlet gap 100 have a larger flow rate, and further enhances the initial water flow velocity of the water flow in the water outlet gap 100 along the water outlet direction, which is beneficial to further offset the influence of centrifugal force on the rotating water outlet curtain, and enhance the anti-splashing ability, flushing effect and massage effect of the rotating water outlet curtain.

[0070] like Figure 5 and Figure 6 As shown, the water outlet direction of the water channel 200 is inclined relative to the axis and radial direction of the rotating part 2, and the tangential component of the inclined direction is opposite to the rotation direction of the rotating part 2. The water flow guided by the water channel 200 can exert a thrust opposite to the rotation direction of the rotating part 2 when impacting the rotating part 2 (especially impacting the groove wall of the water outlet groove 210), so that the rotation speed of the rotating part 2 is reduced, thereby reducing the centrifugal force exerted on the rotating water curtain, and further helping to reduce the opening angle of the water curtain relative to the water outlet direction and weakening the tendency of the water curtain to fly toward the periphery, so as to improve the fullness, flushing effect and massage effect of the rotating water curtain.

[0071] Better, if Figure 4 As shown, in this embodiment, the water outlet trough 210 is provided with an inclined trough section extending to the opening at its bottom end, and the inclined direction of the inclined trough section is opposite to the rotation direction of the rotating part 2, so that the water outlet direction of the water outlet trough 210 is inclined relative to the axial direction of the rotating part 2 and the inclined direction is opposite to the direction of the rotating part 2, that is, the water outlet direction of the water outlet trough 210 is opposite to the direction of the centrifugal force exerted on the rotating water outlet water channel, which reduces the influence of the centrifugal force from the tangential direction, weakens the inertia of the rotating water outlet curtain thrown out in the rotation direction under the action of centrifugal force, thereby further reducing the angle of the rotating water outlet curtain relative to the water outlet direction and weakening the phenomenon of the water outlet curtain flying to the periphery.

[0072] Better, if Figure 7 and Figure 8 As shown, the water hole 134 on the sealing cover 13 points to the rotating part 22 in a direction parallel to the rotation axis, which guides the water flow to impact the rotating part 22 and applies rotational resistance to the rotating part 22 to reduce the rotation speed of the rotating part 2 and further reduce the influence of centrifugal force on the rotating water curtain.

[0073] It can be seen that this embodiment mainly achieves the effect of reducing the opening angle of the rotating water outlet curtain relative to the water outlet direction and preventing the water outlet curtain from splashing to the periphery through the above six methods. Among them, the first three methods mainly enhance the initial water outlet velocity of the water flow in the water outlet gap 100 step by step through three aspects, so as to achieve the purpose of offsetting the influence of centrifugal force on the rotating water outlet curtain. The last three methods directly weaken the influence of centrifugal force from the tangential direction, which can also achieve the purpose of reducing the opening angle of the rotating water outlet curtain. The combination of the six aspects makes the opening angle of the rotating water outlet curtain relative to the water outlet direction controllable and achieves a good anti-splashing effect. The rotating water outlet curtain in this embodiment is surrounded by the outer periphery of the water splash flowing out of the water outlet channel 23, so it can block the water splash from the water outlet channel 23 to prevent it from splashing, so that the overall water outlet has a better anti-splashing effect.

[0074] It should be noted that in actual application, the first three methods can achieve a good splash-proof effect to a certain extent. Therefore, in order to meet the needs of some special scenes that have requirements on the particle size of the water spray, such as Figure 16 As shown, by setting the water outlet direction of the water channel 200 to be inclined relative to the axial and radial directions of the rotating part 2 and the tangential component of the inclined direction is the same as the rotation direction of the rotating part 2, it is beneficial to enhance the water outlet flow rate of the rotating water flow along the rotation to an objectively permitted extent, thereby providing water sprays with finer particle size for these usage scenarios.

[0075] When assembling the water outlet device provided in this embodiment, first, the part of the protrusion 21 of the impeller with the protrusion 212 is extended from the side of the inner cavity of the seat body 121 into the water outlet hole, the second sealing ring 4 is placed on the step surface 1212 of the seat body 121, and the sealing cover 13 is covered on the open end of the seat body 121 with the rib 133 facing outward. The various grooves 132 on it are aligned with the various buckles 1213 on the seat body 121 and snapped together, the first sealing ring 3 is sleeved in the annular limiting groove 1214 on the outer wall of the seat body 121, and then the base 12 is screwed into the installation cavity 112 of the shell 11 with the sealing cover 13 facing the shoulder 110 of the step hole in the shell 11. When the rib 133 on the sealing cover 13 abuts against the shoulder 110 of the step hole in the shell 11, the installation is completed.

[0076] The water outlet device provided in this embodiment has the water outlet effects of inner rotating water splashes and outer rotating water curtains. The outer circle rotating water splashes surround the outer periphery of the inner circle water splashes, so that the inner circle water splashes cannot splash out. On the whole, the water outlet device has a large water outlet distribution area, good massage effect and strong anti-splashing ability of the water outlet flow.

[0077] The above description and embodiments are used to explain the protection scope of the present invention, but do not constitute a limitation on the protection scope of the present invention.
