Description

Technical Field

[0001] The present invention relates to the technical field of push valves, and in particular to a push valve and a water outlet using the push valve. Background Art

[0002] Existing push valves are generally installed in water outlet equipment such as faucets and shower heads to open and close or switch water outlets. Existing push valves usually use a ballpoint pen structure in conjunction with a pilot structure to achieve water outlet control. It is necessary to set many components on the upper end of the guide rod of the push valve to achieve the push positioning function. For example, it is necessary to set a slide groove with several parking positions on the inner wall of the shell, and it is necessary to set two push components for ratchet matching, and an elastic member for resetting. The overall structure is relatively complex, and the manufacturing and assembly costs are high. 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 push valve and a water outlet using the push valve, which have a simple structure and are easy to assemble, thereby reducing the manufacturing and assembly costs.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A push valve comprises: a valve body, which is provided with at least one inlet and outlet water channel; a valve core, which is used to switch the water flow state of the inlet and outlet water channel, which extends out of the valve body and slides relative to the valve body in a pressing direction when under pressure, and is provided with a closed slide groove; an elastic member, which pushes the valve core to slide away from the pressing direction when the valve core is released; a positioning member, which is installed on the valve body and slides cyclically in the slide groove along a preset direction during the sliding process of the valve core; the slide groove is provided with at least two parking positions in the sliding direction of the valve core; when the positioning member switches to park at the parking position after the valve core is released, the valve core opens or closes the inlet and outlet water channel.

[0006] Furthermore, the slide groove is provided with a turning position between any two stop positions; any of the stop positions is located before the turning positions on both sides thereof in the pressing direction of the valve core; the positioning member moves from a stop position of the slide groove to the next adjacent turning position when the valve core is pressurized, and moves from a turning position of the slide groove to the next adjacent stop position when the valve core is released.

[0007] Furthermore, the positioning member maintains sliding connection with the slide groove by deformation or hinged connection to the valve body and always presses against the bottom of the slide groove; the slide groove forms a groove section between any turning position and the parking position, and in the sliding direction of the positioning member, the groove bottom of the starting end of each groove section is lower than the groove bottom of the end of another groove section connected to it.

[0008] Furthermore, the parking position includes a first parking position and a second parking position; the turning position includes a first turning position and a second turning position; the slide groove is provided with a first groove section starting from the first parking position, a second groove section starting from the first turning position, a third groove section starting from the second parking position and a fourth groove section starting from the second turning position in a cyclical manner; the positioning member slides from the first parking position to the first turning position along the first groove section or slides from the second parking position to the second turning position along the third groove section when the valve core is pressurized, and slides from the first turning position to the second parking position along the second groove section or slides from the second turning position to the first parking position along the fourth groove section when the valve core is released.

[0009] Further, along the pressing direction, the first parking position is located behind the second parking position.

[0010] Furthermore, the valve body is provided with a water inlet, a first water outlet and a second water outlet, and respectively form a first inlet and outlet water path and a second inlet and outlet water path; the valve body is provided with a first water pass surface and a second water pass surface between the water inlet and the first water outlet, and between the water inlet and the second water outlet, respectively; when the valve core slides relative to the valve body and abuts against the first water pass surface, the first inlet and outlet water path is closed and the second inlet and outlet water path is opened, and the positioning member is located in the first parking position; when the valve core slides relative to the valve body and abuts against the second water pass surface, the second inlet and outlet water path is closed and the first inlet and outlet water path is opened, and the positioning member is located in the second parking position.

[0011] Furthermore, along the pressing direction, the first water passing surface is located in front of the second water passing surface; when the positioning member is located at the first parking position, it is hooked on the groove wall of the slide groove to keep the valve core in a position abutting the first water passing surface.

[0012] Furthermore, the valve core includes a valve stem and a sealing gasket; the valve stem is sealingly inserted into the valve body and slides relative to the valve body, one end of which extends out of the valve body for pressing, and is provided with a gasket mounting groove that is smaller in diameter than the valve stem itself; the sealing gasket is sleeved on the gasket mounting groove on the valve stem, and the thickness of the sealing gasket is smaller than the width of the gasket mounting groove.

[0013] Furthermore, it also includes an abutment spring; the outer side wall of the valve stem extends outwardly and is provided with an abutment flange; one end of the abutment spring abuts against the abutment flange, and the other end abuts against the sealing gasket, and pushes the sealing gasket to abut against the side wall of the gasket installation groove.

[0014] In addition, the present invention also provides a water outlet, which includes a main body, in which a press valve as described in any of the above items is installed.

[0015] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. An inlet and outlet water channel is arranged in the valve body for realizing water inlet and water outlet. The valve core slides in the valve body and switches the inlet and outlet water channels to be opened or closed through sliding control. One end of the valve core extends out of the valve body for the user to press and drive the valve core to slide. The valve core also cooperates with an elastic member. When the user releases the valve core, the elastic member pushes the valve core to slide in a direction away from the pressing direction, thereby realizing automatic resetting of the valve core. In addition, a positioning member is arranged, and a slide groove is arranged on the valve core at the same time. The positioning member is fixed on the valve body, and it also slides cyclically in the slide groove along a preset direction. At least two parking positions are arranged on the slide groove. When the valve core is pressed, the positioning member slides along the slide groove, and the valve core is in a state of being closed. When the core is released, the valve core is reset under the action of the elastic member until the positioning member slides to one of the parking positions. At this time, the valve core is located at a position to open or close the inlet and outlet water channels. Similarly, in the other parking position, the valve core is located at a position opposite to the previous parking position to control the water flow state of the inlet and outlet water channels. Through the cooperation of the slide groove on the valve core and the positioning member, the valve core can be conveniently limited to the position where it needs to be docked to control the water flow state of the inlet and outlet water channels. Compared with the conventional push valve structure, its internal structure is simple. It is only necessary to set a slide groove on the valve core and add a positioning member. The assembly process is also relatively simple, and the overall manufacturing cost is greatly reduced.

[0017] 2. A turning position is set between the two stop positions of the slide. When the valve core is pressed, the positioning member moves from the stop position to the turning position. At the turning position, the valve core can no longer be pressed by the positioning member. At this time, the valve core is released and reset under the action of the elastic member. The positioning member moves from the turning position to the next stop position, so that the positioning member can slide cyclically in the slide.

[0018] 3. When the positioning piece slides in the slide groove, the part inserted into the slide groove and the other parts need to move relative to each other. Therefore, the positioning piece can achieve this relative movement by deformation or hinged connection to the valve body, and the positioning piece always abuts against the bottom of the slide groove. At the same time, the bottom of the slide groove has a corresponding slope. When entering from one groove section to another, the part of the positioning piece abutting against the bottom of the groove will drop from the height of the previous groove section to the height of the next groove section, thereby preventing the positioning piece from returning to the previous groove section, so that the positioning piece can slide in the slide groove along the preset direction.

[0019] 4. There are two parking positions and two turning positions, forming four connected groove sections. The positioning parts slide in these four groove sections in sequence. The corresponding valve core also has two positions for controlling the water flow state of the inlet and outlet water channels, which can realize the opening and closing of a single inlet and outlet water channel, or the switching of the water flow of two inlet and outlet water channels.

[0020] 5. The first stop position is located behind the second stop position in the pressing direction, so the first stop position is ensured. During the release of the valve core, when the positioning member slides to the first stop position, the positioning member will restrict the valve core from sliding further.

[0021] 6. Two water inlet and outlet passages are provided so that the push valve can switch the water outlet. When the positioning member is located at the first stop position, the first water inlet and outlet passage is closed and the second water inlet and outlet passage is opened. When the positioning member is located at the second stop position, the second water inlet and outlet passage is closed and the first water inlet and outlet passage is opened. Furthermore, by making the valve core abut against the second water flow surface, the valve core is prevented from continuing to move under the action of the elastic member.

[0022] 7. The first water passing surface is located on the front side of the second water passing surface in the pressing direction, and when the positioning member is located at the first parking position, the valve core is kept at the first water passing surface by hooking on the groove wall of the slide groove, preventing the valve core from continuing to move under the action of the elastic member.

[0023] 8. The valve core includes a valve stem and a sealing gasket. The valve stem is sealed with the valve body. The sealing gasket is used to abut the first water pass surface and the second water pass surface, and the thickness of the sealing gasket is smaller than the width of the gasket mounting groove on the valve stem, so that the sealing gasket can move within the range of the gasket mounting groove to avoid excessive deformation of the sealing gasket when the valve core is pressed, thereby reducing the service life.

[0024] 9. An abutment spring is also provided to ensure that the blocking gasket is tightly abutted against the first water passing surface under normal circumstances. At the same time, when the positioning member is located at the first stop position, pressing the valve core will cause the blocking gasket to be subjected to a force moving toward the first water passing surface. The abutment spring can make the blocking gasket move a short distance relative to the valve stem, thereby avoiding excessive deformation of the blocking gasket and reducing its service life.

[0025] 10. Provide a water outlet, in which the above-mentioned pressing valve is installed in the body of the water outlet, and the water path can be switched by driving the valve core of the pressing valve. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] See also Figure 1 , Figure 1 FIG. 1 shows a schematic structural diagram of an embodiment of a press valve provided by the present invention, such as Figure 1 As shown, the push valve provided in this embodiment includes a valve body, a valve core, an elastic member 33 and a positioning member 50 , wherein the valve body includes a valve housing 10 and a base 40 , and the valve core includes a valve stem 20 and a blocking gasket 31 .

[0042] Generally speaking, the valve body is provided with at least one inlet and outlet waterway, and the valve core is used to switch the water flow state of the inlet and outlet waterway on the valve body, such as opening or closing the corresponding inlet and outlet waterway, and the valve core extends out of the valve body so as to slide relative to the valve body in the pressing direction when under pressure, and a closed slide groove is provided on the valve core. The elastic member 33 pushes the valve core to slide away from the pressing direction when the valve core is released; the positioning member 50 is installed on the valve body, and slides cyclically in the slide groove along a preset direction during the sliding process of the valve core. The slide groove is provided with at least two parking positions in the sliding direction of the valve core. When the positioning member 50 switches to the parking position after the valve core is released, the valve core opens or closes the corresponding inlet and outlet waterway.

[0043] In this embodiment, the valve body is provided with two inlet and outlet water passages, and the valve core realizes position change by sliding relative to the valve body, and opens one of the inlet and outlet water passages and closes the other inlet and outlet water passage at the corresponding position; at the same time, corresponding to the position change of the valve core, the slide groove is provided with two stop positions, and the positioning member 50 switches between the two stop positions, and opens the corresponding inlet and outlet water passage and closes the other inlet and outlet water passage when it is located at one of the stop positions, and the same is true when it is located at the other stop position.

[0044] In order to realize the arrangement of two water inlet and outlet paths on the valve body, in this embodiment, the valve body is provided with a water inlet 12, a first water outlet 41 and a second water outlet 11, and the first water inlet and outlet paths and the second water inlet and outlet paths are formed respectively, and the valve body is provided with a first water passing surface and a second water passing surface respectively between the water inlet 12 and the first water outlet 41, and between the water inlet 12 and the second water outlet 11. Along the pressing direction, the first water passing surface is located in front of the second water passing surface.

[0045] Specifically, the valve body is composed of a valve housing 10 and a base 40, which are fixed by a threaded connection. The valve housing 10 is roughly cylindrical, and a sliding cavity is formed inside the valve housing 10 along the axial direction. At the same time, part of the sliding cavity also serves as the water passage cavity of the valve housing 10. At the position corresponding to the water passage cavity, the side wall of the valve housing 10 is provided with the above-mentioned water inlet 12 and the second water outlet 11, and as shown in FIG. Figure 2 As shown, a second water-passing surface is formed between the water inlet 12 and the second water outlet 11. The second water-passing surface can be regarded as a continuous, annular step formed along the peripheral edge of the side wall of the sliding cavity inside the valve housing 10. Figure 2 In the direction shown, the water inlet 12 is located below the second water outlet 11 , and the second water flow surface is located between the two and faces the position where the water inlet 12 is located.

[0046] The structure of the base 40 is as follows Figure 3 and Figure 4 As shown, a chamber is also formed inside the valve housing 10, which cooperates with the internal sliding chamber of the valve housing 10 to form a complete water passage chamber in the push valve in this embodiment. The side wall of the base 40 is provided with the first water outlet 41 mentioned above. Figure 2 In the direction shown, the first water outlet 41 is located below the water inlet 12. When the external water is connected, the water flows into the water passage cavity from the water inlet 12, and under the action of the valve core, it can flow out through the first water outlet 41, which is the first water inlet and outlet water path mentioned above, or it can flow out through the second water outlet 11, which is the second water inlet and outlet water path mentioned above. At the same time, a first water passage surface is also formed between the water inlet 12 and the first water outlet 41. The first water passage surface can be regarded as a continuous, annular step formed along the peripheral edge of the side wall of the internal chamber of the base 40, which faces the position where the water inlet 12 is located.

[0047] At the bottom of the base 40 (with Figure 2 The base 40 is provided with a mounting structure of a positioning member 50. Specifically, an insertion hole 42 is provided at the bottom of the base 40, which penetrates from the outside to the inside of the base 40. A circle of clamping grooves 43 are provided along the peripheral edge of the outer wall of the base 40 near the bottom end face of the base 40. At the same time, a clearance groove 44 is provided on the bottom end face of the base 40 between the insertion hole 42 and the clamping groove 43. One end of the clearance groove 44 is connected to the side wall of the insertion hole 42, and the other end is connected to the side wall of the clamping groove 43. In the internal chamber of the base 40, a sliding hole 45 is formed through the side wall. The sliding hole 45 provides a moving space for the valve core. A plurality of base guide walls 46 are provided at the upper end of the side wall of the sliding hole 45. The base guide walls 46 are inclined and open upward to guide the valve core to fall into the sliding hole 45 when the valve core is assembled.

[0048] The positioning member 50 maintains a sliding connection with the slide groove by deformation or hinged to the valve body. In this embodiment, the positioning member 50 has a deformation function and can maintain a sliding connection with the slide groove by deformation. Specifically, the positioning member 50 is a metal hook with a certain deformation property, such as Figure 3 As shown, it includes a clamping portion 51, which is an annular structure and can be clamped into the clamping groove 43 at the bottom of the base 40; it also includes a deformation portion 52, which is formed by extending and bending the clamping portion 51, and can be regarded as a rod-shaped structure. The rod-shaped structure as a whole can move relative to the clamping portion 51 within a three-dimensional conical range with the connection point between the two as the pole; it also includes a plug-in portion 53, which is connected to the end of the deformation portion 52, can be inserted into the slide groove on the valve core, and can change with the position of the deformation portion 52. There is a connecting section between the clamping portion 51 and the deformation portion 52, one end of which extends into the middle position of the clamping portion 51, and the deformation portion 52 is upward (with a rotation angle of 0.1mm) at this end of the connecting section. Figure 2 The surface of the substrate is formed by extending in the direction of the substrate.

[0049] When the positioning member 50 is installed on the base 40, the clamping portion 51 of the positioning member 50 is first opened, and then released after it is inserted into the clamping groove 43 on the base 40, so that the clamping portion 51 is clamped in the clamping groove 43, and at the same time, the deformable portion 52 is allowed to enter the internal chamber of the base 40 along the insertion hole 42 of the base 40, and the connecting section on the positioning member 50 is placed in the clearance groove 44 on the base 40, thereby completing the installation of the positioning member 50. It should be noted that the insertion hole 42 has a certain space, and the deformable portion 52 of the positioning member 50 can move relative to the clamping portion 51 in this space.

[0050] The valve core includes a valve stem 20 and a blocking gasket 31, and a slide groove is arranged on the valve stem 20. The slide groove is provided with a turning position between any two stop positions, and any stop position is located before the turning positions on both sides thereof in the pressing direction of the valve core; the positioning member moves from a stop position of the slide groove to the next adjacent turning position when the valve core is pressed, and moves from a turning position of the slide groove to the next adjacent stop position when the valve core is released. The slide groove forms a groove section between any turning position and the stop position, and in the sliding direction of the positioning member 50, the groove bottom of the starting end of each groove section is lower than the groove bottom of the end of another groove section connected thereto.

[0051] Specifically, in the present embodiment, the parking positions include a first parking position 231 and a second parking position 233, and the turning positions include a first turning position 232 and a second turning position 234; the slide groove is provided with a first groove section 241 starting from the first parking position 231, a second groove section 242 starting from the first turning position 232, a third groove section 243 starting from the second parking position 233, and a fourth groove section 244 starting from the second turning position 234 in a cyclical manner; when the valve core is pressurized, the positioning member 50 slides from the first parking position 231 to the first turning position 232 along the first groove section 241 or slides from the second parking position 233 to the second turning position 234 along the third groove section 243, and when the valve core is released, it slides from the first turning position 232 to the second parking position 233 along the second groove section 242 or slides from the second turning position 234 to the first parking position 231 along the fourth groove section 234. Furthermore, along the pressing direction of the valve core, the first parking position 231 is located behind the first parking position 233 .

[0052] like Figure 5 , Figure 6 and Figure 7 As shown, the lower end of the valve stem 20 has a section extending into the inner chamber of the base 40, and a flat wall facing the positioning member 50 is formed on the stem of the valve stem 20 in this section, and the slide groove is arranged on the flat wall. The slide groove is a sink groove, which has a groove bottom, and the slide groove is continuous and closed, and its head end and the tail end are connected. In this embodiment, the slide groove is roughly formed into a "heart" shape. Figure 5As shown, with the first stop position 231 in the middle of the heart-shaped slide as the starting point, the slide can be divided into four connected slot sections according to the position of the direction turning, the starting point of the first slot section 241 is the first stop position 231, and the end point is the first turning position 232, the starting point of the second slot section 242 is the first turning position 232, and the end point is the second stop position 233, the starting point of the third slot section 243 is the second stop position 233, and the focus is the second turning position 234, and the starting point of the fourth slot section 244 is the second turning position 234, and the end point is the first stop position 231. In addition, in order to allow the plug-in portion 53 of the positioning member 50 to slide in the slide along the preset direction, on the basis that the deformation portion 52 of the positioning member 50 keeps the end of the plug-in portion 53 against the bottom of the slide by elastic force, the bottom of the slide itself also has a corresponding structure. Taking the plane where the starting position of each slot section is located as the reference plane, the plane where the end position of the slot section is located must be higher than the reference plane, and at the same time higher than the plane where the starting point of the next slot section is located. That is to say, each slot section has a certain slope. For example, in the process of moving from the first stop position 231 to the first turning position 232, the plug-in portion 53 of the positioning member 50 is gradually lifted relative to the first stop position 231. When entering the first turning position 232, it suddenly drops and is blocked by the limiting wall on the bottom of the slot here, so that the plug-in portion 53 cannot return to the first slot section 241, so that the plug-in portion 53 can only slide in the slide groove along the counterclockwise direction (referring to the present embodiment).

[0053] The valve stem 20 is sealed and plugged into the valve body and slides relative to the valve body. One end of the valve stem 20 extends out of the valve body for pressing. The valve stem 20 is provided with a gasket installation groove 21 that is smaller in diameter than the valve stem 20 itself. The blocking gasket 31 is sleeved on the gasket installation groove 21 on the valve stem 20, and the thickness of the blocking gasket 31 is smaller than the width of the gasket installation groove 21. In addition, an abutment spring 32 is sleeved on the valve stem 20. The outer side wall of the valve stem 20 is provided with an abutment flange 25 extending outward. One end of the abutment spring 32 abuts against the abutment flange 25, and the other end abuts against the blocking gasket 31, and pushes the blocking gasket 31 to abut against the side wall of the gasket installation groove 21.

[0054] Specifically, Figure 2 and Figure 5 As shown in the figure, a circle of inwardly recessed gasket installation groove 21 is provided in the middle of the valve stem 20. Based on the diameter of most of the stem of the valve stem 20, the diameter of the valve stem 20 is reduced at the gasket installation groove 21, thereby forming a circle of sunken grooves, and the plugging gasket 31 can be sleeved in the gasket installation groove 21. The plugging gasket 31 is made of rubber and has a certain elasticity. Its thickness is smaller than the width of the gasket installation groove 21. When the plugging gasket 31 is sleeved in the gasket installation groove 21, the plugging gasket 31 can slide up and down in the gasket installation groove 21 relative to the valve stem 20. In this way, when the plugging gasket 31 is located in the gasket installation groove 21, the plugging gasket 31 can slide up and down in the gasket installation groove 21. Figure 7When the valve stem 20 is in the position shown, the valve stem 20 is continuously pressed downward, and the blocking gasket 31 can move upward a short distance relative to the valve stem 20, thereby preventing the blocking gasket 31 from being deformed too much. The blocking gasket 31 is used to abut against the first water passing surface and the second water passing surface to close the corresponding first inlet and outlet waterways and the second inlet and outlet waterways.

[0055] In addition, an abutment flange 25 is provided at the upper part of the valve stem 20. The abutment flange 25 is formed by extending outward from the outer side wall of the valve stem 20, and its downward side wall is used for abutment by the abutment spring 32. The lower end of the abutment spring 32 abuts against the upper side wall of the sealing gasket 31, and applies force to push the sealing gasket 31 against the lower side groove wall of the gasket mounting groove 21. Through the action of the abutment spring 32, the sealing gasket 31 can maintain a large abutment force when abutting the first water flow surface, thereby ensuring the sealing effect.

[0056] At the same time, the elastic member 33 is also sleeved on the valve stem 20, and a step portion is provided on the base 40. The lower end of the elastic member 33 abuts on the step portion, and the upper end abuts on the lower side wall of the blocking gasket 31. Due to the action of the abutting spring 32, the elastic member 33 abuts on the blocking gasket 31, which is equivalent to acting on the entire valve core. When the valve core is released, the elastic member 33 can drive the valve core to slide upward by pushing the blocking gasket 31.

[0057] When using, Figure 7 The state shown is the starting state, at which time the plug-in portion 53 of the positioning member 50 is located at the first stop position 231 of the slide slot and is hooked on the slot wall of the slide slot, so that the valve stem 20 cannot slide upward, and the blocking gasket 31 remains in contact with the first water passing surface, thereby closing the first inlet and outlet waterway and opening the second inlet and outlet waterway; then, the end of the valve stem 20 is pressed, and the plug-in portion 53 slides from the first stop position 231 to the first turning position 232. At this time, the valve stem 20 cannot be pressed anymore. After the valve stem 20 is released, the valve core slides upward under the action of the elastic member 33, and at the same time, the plug-in portion 53 moves along the second slot section 242 to the second stop position 233. At this time, the state is as shown in FIG. Figure 6 As shown, the blocking gasket 31 abuts against the second water flow surface, thereby closing the second inlet and outlet waterway and opening the first inlet and outlet waterway; then the valve stem 20 is pressed, and the plug-in portion 53 slides from the second stop position 233 along the third groove section 243 to the second turning position 234, and then the valve stem 20 is released, and the valve core slides upward under the action of the elastic member, and at the same time the plug-in portion 53 moves along the fourth groove section 244 to the first stop position 231, completing a cycle.

[0058] In this embodiment, the blocking gasket 31 is restrained from further movement by abutting against the second water-passing surface. In other embodiments, if no water-passing surface is provided toward the blocking gasket 31, the blocking gasket 31 can also be limited by hooking the plug-in portion 53 on the wall of the slide groove at the second stop position.

[0059] In addition, the present invention also provides a water outlet, which includes a main body with an installation cavity provided in the main body. The push valve provided in the above embodiment is installed in the installation cavity, and the main body is connected to an external water inlet pipe, and is also connected to two water outlet pipes. The water inlet pipe is also connected to the water inlet 12 of the push valve, and the two water outlet pipes are respectively connected to the first water outlet 41 and the second water outlet 11 of the push valve.

[0060] The present invention provides a push valve and a water outlet using the push valve. A valve core that can slide relative to a valve body is provided, and a slide groove for sliding engagement of a positioning member 50 is provided on the valve core. The positioning member 50 cooperates with the wall of the slide groove so that the valve core can stop at a preset position during the sliding process, thereby realizing the function of switching the water outlet state of the water path. The overall structure is simple, and only a positioning member 50 needs to be added. The assembly process is also relatively simple, and the overall manufacturing cost is greatly reduced.

[0061] 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 on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
