Abstract

The application discloses a connecting rod structure and a water dispenser. The connecting rod structure comprises a shell, a push rod, a pull rod and an elastic member. The shell is provided with an accommodating cavity. The push rod is arranged on the shell. An annular groove is formed in the side wall of the push rod. The push rod segment where the annular groove is located is arranged in the accommodating cavity. The annular groove comprises a first guide segment, a limiting segment and a second guide segment which are sequentially connected in a head-tail mode. The pull rod is rotationally connected with the shell and is arranged in the accommodating cavity. The pull rod is provided with a limiting part which is inserted into the annular groove. The elastic member is arranged in the accommodating cavity and is connected with the push rod. The push rod is used for sliding relative to the shell under the action of an external force and compressing the elastic member. The pull rod is used for sliding the limiting part along the first guide segment during the sliding process of the push rod.

After the limiting part slides from the limiting segment to the second guide segment, the push rod is released to make the push rod reversely slide under the action of the restoring force of the elastic member.

Description

Technical Field

[0001] This application relates to the field of drinking water equipment technology, specifically to a linkage structure and a water dispenser. Background Technology

[0002] Water dispensers are a common household appliance. The water dispensing control methods on water dispensers are generally divided into manual control and electronic automatic control. Compared to electronic automatic control, manual control requires the user to continuously press and hold the water dispensing button to dispense water. When the user dispenses a large amount of water at a time, or when the water dispensing speed of a dispenser with a filtration system is low, the user needs to maintain the dispensing action for an extended period until the desired amount of drinking water is obtained, resulting in a poor user experience. Summary of the Invention

[0003] This application provides a linkage structure and a water dispenser, which aims to solve the problem that when a user takes a large amount of water at a time or when the water dispenser with a filtration system has a low water output speed, the user needs to maintain the water-taking action for a long time until the required amount of drinking water is obtained, resulting in a poor user experience.

[0004] In a first aspect, embodiments of this application provide a linkage structure, including:

[0005] The shell defines a receiving cavity;

[0006] A push rod is inserted through the housing. An annular groove is formed on the side wall of the push rod. The push rod section containing the annular groove is located in the receiving cavity. The annular groove includes a first guide section, a limiting section, and a second guide section that are connected end to end in sequence.

[0007] A pull rod is rotatably connected to the housing and located within the receiving cavity. The pull rod has a limiting part that is inserted into the annular groove.

[0008] An elastic element is disposed within the receiving cavity and connected to the push rod;

[0009] The push rod is configured to slide relative to the housing under the action of an external force and compress the elastic element. The pull rod is configured to cause the limiting portion to slide along the first guide section during the sliding of the push rod, and to tighten the push rod after the limiting portion slides from the first guide section to the limiting section to prevent the push rod from sliding in the opposite direction under the action of the restoring force of the elastic element. After the limiting portion slides from the limiting section to the second guide section, the push rod is released to cause the push rod to slide in the opposite direction under the action of the restoring force of the elastic element.

[0010] This application employs a push rod and a pull rod in combination. When the push rod is pressed, causing it to slide within the housing, it compresses the elastic element, and the limiting part of the pull rod slides along the first guide section towards the limiting section. After the limiting part of the pull rod slides to the limiting section, the pull rod pulls the push rod tight, restricting the push rod from sliding backward under the restoring force of the elastic element. When the linkage structure is applied to a water dispenser, it connects the water dispensing button and the faucet. When the water dispensing button is pressed, it drives the push rod to slide until the limiting part of the pull rod is located in the limiting groove of the annular groove. Through the cooperation of the pull rod and the push rod, the faucet can be kept open (i.e., open and locked), thus facilitating water dispensing when the single water volume is large or the water dispensing speed of the water dispenser is low. After dispensing water, pressing the water dispensing button again will continue to drive the push rod to slide, causing the limiting part to slide from the limiting section to the second guide section. When the external force applied to the water dispensing button is released (i.e., when the user releases the button), the push rod slides in the opposite direction under the restoring force of the elastic element. During this reverse sliding, the faucet returns from the open to the closed state, stopping the water dispenser from dispensing water. Throughout the entire water dispensing process, the user does not need to maintain a water-dispensing action for an extended period until the desired amount of drinking water is obtained, thus improving the user experience.

[0011] In some embodiments, the push rod includes a first extension and a second extension, the annular groove is formed at a first end of the first extension, the second extension is connected to the first end and located on one side of the first extension, the second extension and the first end define a clearance portion, and the pull rod is disposed in the clearance portion.

[0012] In some embodiments, the push rod further includes a connecting arm connected to the first end and located on opposite sides of the second extension, the connecting arm being connected to the elastic element.

[0013] In some embodiments, the housing includes a first plate and a second plate spaced apart within the receiving cavity, a mounting groove is defined between the first plate and the second plate, the elastic member is disposed within the mounting groove, and the connecting arm extends into the mounting groove and connects to the elastic member.

[0014] In some embodiments, the pull rod further includes a pivot portion and a connecting portion. The two opposite ends of the connecting portion are respectively connected to the limiting portion and the pivot portion. The pivot portion is rotatably connected to the first plate and the second plate. The pull rod is rotatably connected to the housing through the pivot portion.

[0015] In some embodiments, the bottom of the annular groove is provided with an anti-reverse structure, and a first abutment and a second abutment are spaced apart on the rotating shaft. The second extension has a traction portion on the side near the rotating shaft. The traction portion is located between the first abutment and the second abutment. The traction portion is configured to cooperate with the first abutment and the second abutment during the sliding of the push rod, so that the rotating shaft moves along its axial direction and drives the limiting portion to move along the depth direction of the annular groove, so that the limiting portion cooperates with the anti-reverse structure to restrict the limiting portion from sliding in the reverse direction along the annular groove.

[0016] In some embodiments, the anti-reverse structure includes a plurality of steps disposed at the bottom of the annular groove along the extension direction of the annular groove. During the sliding of the limiting part along the first guide segment, the limiting segment and the second guide segment, the limiting part moves along the depth direction of the annular groove, such that the distance between the free end of the limiting part and the step surface of the step is less than the height difference between the step and the previous step.

[0017] In some embodiments, along the sliding direction from the first guide segment, through the limit segment to the second guide segment, the height of the steps corresponding to the first guide segment, the limit segment, and the second guide segment gradually decreases.

[0018] In some embodiments, along the sliding direction from the first guide segment through the limiting segment to the second guide segment, the step height at the bottom of the annular groove varies in an arithmetic sequence.

[0019] In some embodiments, the traction portion includes a traction body, a first protrusion, and a second protrusion. The traction body is disposed on the second extension and faces the avoidance portion. The first protrusion and the second protrusion are respectively disposed on both sides of the traction body.

[0020] The first protrusion is configured to cooperate with the first abutment during the sliding of the push rod, so that the rotating shaft drives the limiting part to move away from the bottom of the annular groove, so that the limiting part moves from the last step of the second guide section to the first step of the first guide section;

[0021] The second protrusion is configured to cooperate with the second abutment during the sliding of the push rod, so that the rotating shaft drives the limiting part to move toward the bottom of the annular groove, so that the distance between the free end of the limiting part and the step surface of the step is always less than the height difference between the step and the previous step.

[0022] In some embodiments, the push rod further includes a third extension connected to the end of the second extension away from the first extension, and the third extension and the connecting arm are located on opposite sides of the second extension.

[0023] Secondly, this application provides a water dispenser, comprising:

[0024] Organism;

[0025] Buttons are located on the body of the device;

[0026] The faucet is located at the end of the machine body furthest from the button;

[0027] As described in the first aspect, the linkage structure is disposed in the body of the machine and connects the button and the faucet. The linkage structure is configured such that when the limiting part slides from the first guide section to the limiting section, the pull rod pulls the push rod, so that the faucet is in a locked state that keeps it open; and after the limiting part slides from the limiting section to the second guide section, the pull rod releases the push rod, so that the faucet is released from the locked state.

[0028] In some embodiments, the faucet is further provided with a reset member, the reset member being elastic and configured to drive the faucet to close, the reset member having the same elastic force and stroke as the elastic member. Attached Figure Description

[0035] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0036] This application provides a linkage structure and a water dispenser. Detailed descriptions are provided below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0037] First, please refer to the following: Figure 1 and Figure 2 The linkage structure includes a housing 1, a push rod 2, a pull rod 3, and an elastic element 4.

[0038] The housing 1 defines a receiving cavity 11. The push rod 2 is slidably mounted on the housing 1. An annular groove 12 is formed on the side wall of the push rod 2. The push rod section containing the annular groove 12 is located within the receiving cavity 11. The annular groove 12 includes a first guide section 121, a limiting section 122, and a second guide section 123 that are connected end to end in sequence.

[0039] The pull rod 3 is rotatably connected to the housing 1 and located within the receiving cavity 11. The pull rod 3 has a limiting part 31. The limiting part 31 is inserted into the annular groove 12. The elastic element 4 is disposed within the receiving cavity 11 and connected to the push rod 2. The push rod 2 is configured to slide relative to the housing 1 under the action of an external force and compress the elastic element 4. The pull rod 3 is configured such that during the sliding of the push rod 2, the limiting part 31 slides along the first guide section 121, and after the limiting part 31 slides from the first guide section 121 to the limiting section 122, the push rod 2 is tightened to prevent the push rod 2 from sliding in the opposite direction under the restoring force of the elastic element 4, and after the limiting part 31 slides from the limiting section 122 to the second guide section 123, the push rod 2 is released, allowing the push rod 2 to slide in the opposite direction under the restoring force of the elastic element 4.

[0040] Specifically, the two ends of the push rod 2 protrude through the opposite side walls of the housing 1, so that the push rod 2 can slide along its own length direction inside the housing 1. This facilitates the sliding of the push rod 2, which in turn drives the first guide section 121, the limiting section 122 and the second guide section 123 to slide relative to the limiting part 31 of the pull rod 3, and to make reciprocating motion under the action of the elastic member 4.

[0041] It is understandable that the push rod 2 moves towards the pull rod 3 under the action of two external forces. Under the action of the first external force, the push rod 2 compresses the elastic element 4, and causes the limiting part 31 to slide relative to the push rod 2 along the first guide section 121 until the limiting part 31 slides from the first guide section 121 to the limiting section 122. At this time, the first external force ends, and the elastic element 4 acts on the push rod 2, causing the pull rod 3 to pull the push rod 2 through the limiting part 31, locking the state of the push rod 2 after sliding under the first external force. Under the second external force, push rod 2 continues to compress elastic element 4, causing limiting part 31 to slide from limiting section 122 to second guide section 123. Pull rod 3 releases push rod 2. At this time, elastic element 4 acts on push rod 2 to reset push rod 2. By locking and releasing push rod 2, it is easy to apply push rod 2 to water dispenser. After the water dispenser button is pressed by the connecting rod, it maintains the water dispensing state. Pressing the button again resets the water dispenser by the connecting rod, eliminating the need for the user to hold the water dispensing action for a long time until the required drinking water is obtained, thereby improving the user experience of using water dispenser.

[0042] Furthermore, the push rod 2 includes a first extension 21 and a second extension 22. An annular groove 12 is formed at the first end of the first extension 21. The second extension 22 is connected to the first end and is located on one side of the first extension 21. The first end of the second extension 22 defines a clearance portion 23. The pull rod 3 is disposed in the clearance portion 23.

[0043] Specifically, the second extension 22 is connected to the side wall of the first extension 21 so that the second extension 22 avoids the extension line of the first extension 21 in the length direction to form a clearance portion 23. The clearance portion 23 allows the push rod 2 to avoid the pull rod 3 when sliding in the housing 1, so that the push rod 2 can slide relative to the pull rod 3, and facilitates the sliding of the limiting portion 31 relative to the push rod 2 between the first guide section 121, the limiting section 122 and the second guide section 123.

[0044] Furthermore, please refer to the following: Figure 2 and Figure 3 The push rod 2 also includes a connecting arm 24. The connecting arm 24 is connected to the first end, that is, the connecting arm 24 is connected to the end of the annular groove 12 of the first extension 21, and is located on opposite sides of the second extension 22 of the first extension 21. The connecting arm 24 is connected to the elastic member 4.

[0045] Specifically, the connecting arm 24 extends in a direction perpendicular to the sliding direction of the push rod 2. A fixing post 241 is connected to the connecting arm 24. In this embodiment, the elastic element 4 includes a spring, one end of which is fixed to the inner wall of the housing 1, and the other end is sleeved on the fixing post 241 and fixed to the connecting arm 24, so that the spring force abuts the connecting arm 24 to drive the push rod 2 to reset.

[0046] Furthermore, please refer to the following: Figure 1 and Figure 3 The housing 1 includes a first plate 13 and a second plate 14 spaced apart within a receiving cavity 11. A mounting groove is defined between the first plate 13 and the second plate 14. An elastic member 4 is disposed within the mounting groove. A connecting arm 24 extends into the mounting groove and connects to the elastic member 4.

[0047] It should be noted that both the first plate 13 and the second plate 14 are located on one side of the sliding path of the first extension 21 and the second extension 22. The ends of the first plate 13 and the second plate 14 near the first extension 21 are connected to each other to restrict the connecting arm 24 from sliding out of the mounting groove. The ends of the first plate 13 and the second plate 14 near the second extension 22 extend to the clearance portion 23 and are located on both sides of the sliding path of the first extension 21.

[0048] Furthermore, please refer to the following: Figure 3 and Figure 4 The pull rod 3 also has a pivot portion 32 and a connecting portion 33. The two ends of the connecting portion 33 are respectively connected to the limiting portion 31 and the pivot portion 32. The two ends of the pivot portion 32 are respectively rotatably connected to the first plate 13 and the second plate 14, and the pull rod 3 is rotatably connected to the housing 1 through the pivot portion 32.

[0049] It is understood that the pivot portion 32 is rotatably connected to one end of the first plate 13 and the second plate 14 extending to the clearance portion 23, and the pivot portion 32 can slide along its own length. The connecting portion 33 is located outside the mounting groove, and the limiting portion 31 is connected to the end of the connecting portion 33 away from the pivot portion 32, so that the limiting portion 31 can slide between the first guide section 121, the limiting section 122 and the second guide section 123 by the rotation of the pivot portion 32.

[0050] In this embodiment, an anti-detachment part 34 is connected to the end of the pivot portion 32 away from the connecting portion 33. The anti-detachment part 34 is located outside the mounting groove and is located on opposite sides of the first plate 13 and the second plate 14, opposite to each other, along with the connecting portion 33. The anti-detachment part 34 and the connecting portion 33 can both form a certain angle with the pivot portion 32 to prevent the pivot portion 32 from detaching from the first plate 13 and the second plate 14.

[0051] For example, the limiting part 31 is perpendicular to the connecting part 33. The connecting part 33 is perpendicular to the rotating shaft part 32, that is, the limiting part 31 is parallel to the rotating shaft part 32. The anti-detachment part 34 is perpendicular to the rotating shaft part 32, that is, the anti-detachment part 34 is parallel to the connecting part 33.

[0052] Furthermore, a reverse-resistance structure 5 is provided at the bottom of the annular groove 12. A first abutment member 35 and a second abutment member 36 are spaced apart on the rotating shaft portion 32. A traction portion 25 is provided on the side of the second extension section 22 near the rotating shaft portion 32. The traction portion 25 is located between the first abutment member 35 and the second abutment member 36. The traction portion 25 is configured to cooperate with the first abutment member 35 and the second abutment member 36 during the sliding of the push rod 2, causing the rotating shaft portion 32 to move along its axial direction, and driving the limiting portion 31 to move along the depth direction of the annular groove 12, so that the limiting portion 31 cooperates with the reverse-resistance structure to restrict the limiting portion 31 from sliding in the reverse direction along the annular groove 12.

[0053] Specifically, the first abutting member 35 and the second abutting member 36 are spaced apart.

[0054] In this embodiment, the first abutment member 35 includes a first flange, and the second abutment member 36 includes a second flange. The first flange and the second flange have the same diameter, and the first flange and the second flange extend radially to both sides of the traction part 25, so that the first flange and the second flange abut against the traction part 25 respectively.

[0055] It is worth noting that the diameters of the first and second flanges are greater than the distance between the axis of the rotating shaft 32 and the traction part 25. The diameter of the rotating shaft 32 is smaller than the distance between the axis of the rotating shaft 32 and the traction part 25, so that the first and second flanges can smoothly abut against the traction part 25.

[0056] It is understandable that during the sliding process of the push rod 2 relative to the housing 1, the limiting part 31 slides within the annular groove 12 along the directions of the first guide section 121, the limiting section 122, and the second guide section 123. During this process, the traction part 25 also slides. During the sliding process of the traction part 25, through its cooperation with the first abutment member 35 and the second abutment member 36, the rotating shaft part 32 moves axially, causing the limiting part 31 to cooperate with the anti-reverse structure 5, thereby preventing the limiting part 31 from sliding in the opposite direction during its sequential movement along the first guide section 121 to the limiting section 122, the limiting section 122 to the second guide section 123, and the second guide section 123 to the first guide section 121.

[0057] Furthermore, please refer to the following: Figure 2 and Figure 4 The anti-reverse structure 5 includes multiple steps disposed at the bottom of the annular groove 12 along the extension direction of the annular groove 12. During the sliding process of the limiting part 31 along the first guide section 121, the limiting section 122 and the second guide section 123, the limiting part 31 moves along the depth direction of the annular groove 12, so that the distance between the free end of the limiting part 31 and the step surface of the step is less than the height difference between the step and the previous step.

[0058] Specifically, the step includes a first limiting platform 51, a second limiting platform 52, and a third limiting platform 53 connected sequentially along the extension direction of the first guide section 121, the limiting section 122, and the second guide section 123. The heights of the first limiting platform 51, the second limiting platform 52, and the third limiting platform 53 decrease sequentially along the sliding direction within the first guide section 121, the limiting section 122, and the second guide section 123.

[0059] It is understood that the steps formed by the first limiting platform 51, the second limiting platform 52, and the third limiting platform 53 form a reverse-slip structure 5, which causes the limiting part 31 to slide in the opposite direction during the movement of the first guide section 121, the limiting section 122, and the second guide section 123. This is because the traction part 25 acts on the rotating shaft part 32, causing the rotating shaft part 32 to cooperate with the first limiting platform 51, the second limiting platform 52, and the third limiting platform 53. This restricts the limiting part 31 from sliding in the opposite direction during the sliding process along the direction from the first limiting platform 51 to the second limiting platform 52 and from the second limiting platform 52 to the third limiting platform 53.

[0060] It is worth noting that along the sliding direction of the limiting part 31 from the first guide section 121, the limiting section 122 and the second guide section 123, the height of the steps corresponding to the first guide section 121, the limiting section 122 and the second guide section 123 gradually decreases, and the height of the steps set at the bottom of the annular groove 12 changes in an arithmetic sequence. In this embodiment, the height difference between two adjacent steps is the same.

[0061] In this embodiment, the first limiting platform 51 corresponds to the first guide segment 121. The second limiting platform 52 corresponds to the limiting segment 122. The third limiting platform 53 corresponds to the second guide segment 123. The height of the first limiting platform 51 is higher than that of the second limiting platform 52, the height of the second limiting platform 52 is higher than that of the third limiting platform 53, and the height difference between the first limiting platform 51, the second limiting platform 52, and the third limiting platform 53 is the same, so as to restrict the reverse sliding of the limiting part 31.

[0062] Furthermore, the traction unit 25 includes a traction body 251, a first protrusion 252, and a second protrusion 253. The traction body 251 is disposed on the second extension section 22 and faces the avoidance section 23, and the first protrusion 252 and the second protrusion 253 are respectively disposed on both sides of the traction body 251.

[0063] The first protrusion 252 is configured to cooperate with the first abutment 35 during the sliding of the push rod 2, so that the rotating shaft 32 drives the limiting part 31 to move away from the bottom of the annular groove 12, so that the limiting part 31 moves from the last step of the second guide section 123 to the first step of the first guide section 121.

[0064] The second protrusion 253 is configured to cooperate with the second abutment 36 during the sliding of the push rod 2, so that the rotating shaft 32 drives the limiting part 31 to move towards the bottom of the annular groove 12, so that the free end of the limiting part 31 is always less than the height difference between the step and the previous step.

[0065] Specifically, the traction body 251 is connected to the side wall of the second extension section 22, and the traction body 251 slides between the mounting slots. The first abutment 35 and the second abutment 36 are located on both sides of the sliding path of the traction body 251, and the first abutment 35 corresponds to the first protrusion 252, and the second abutment 36 corresponds to the second protrusion 253.

[0066] It is understood that when the limiting part 31 is located at the third limiting platform 53, that is, at the second guide section 123, the push rod 2 is in its initial position. Under the action of the first external force, the push rod 2 drives the traction body 251 to slide in the mounting groove, so that the first protrusion 252 contacts the first abutment 35, causing the rotating shaft 32 to drive the limiting part 31 to slide away from the third limiting platform 53, thereby increasing the distance between the limiting part 31 and the third limiting platform 53. This facilitates the movement of the limiting part 31 to correspond with the first limiting platform 51 during the sliding process of the push rod 2, thus facilitating the entry of the limiting part 31 into the first guide section 121. As the push rod 2 continues to slide, the first protrusion 252 slides past the first abutment 35, and the limiting part 31 completely enters the first guide section 121.

[0067] Under the action of the second external force, the push rod 2 drives the traction body 251 to continue sliding in the mounting groove in the same direction as under the action of the first external force. At this time, the limiting part 31 enters the limiting section 122 and corresponds to the second limiting platform 52, so that the second protrusion 253 contacts the second abutting member 36, thereby causing the rotating shaft part 32 to drive the limiting part 31 to slide towards the second limiting platform 52, so as to reduce the distance between the limiting part 31 and the second limiting platform 52 and restrict the limiting part 31 from sliding in the opposite direction to the first limiting platform 51.

[0068] When the limiting part 31 enters the second guide section 123 and corresponds to the third limiting platform 53, it continues to contact the second abutting member 36 through the second protrusion 253, so that the rotating shaft part 32 drives the limiting part 31 to continue sliding towards the third limiting platform 53, so as to reduce the distance between the limiting part 31 and the third limiting platform 53 and restrict the limiting part 31 from sliding in the opposite direction to the second limiting platform 52.

[0069] In this embodiment, the second guide segment 123 includes a connecting guide segment 1231 and an initial guide segment 1232. The connecting guide segment 1231 connects the limiting segment 122 and the initial guide segment 1232. The initial guide segment 1232 connects the connecting guide segment 1231 and the first guide segment 121.

[0070] The third limiting platform 53 also includes a connecting limiting platform 531 and an initial limiting platform 532. The connecting limiting platform 531 is located between the second limiting platform 52 and the initial limiting platform 532. The initial limiting platform 532 is located between the connecting limiting platform 531 and the first limiting platform 51. The height of the connecting limiting platform 531 is lower than that of the second limiting platform 52, and the height of the initial limiting platform 532 is lower than that of the connecting limiting platform 531.

[0071] It is worth noting that the connecting limiting platform 531 corresponds to the connecting guide section 1231. The initial limiting platform 532 corresponds to the initial guide section 1232. The second limiting platform 52 corresponds to the first guide section 121. The third limiting platform 53 corresponds to the limiting section 122. During the sliding process of the push rod 2, the limiting part 31 moves relative to the push rod 2 within the annular groove 12 from the initial guide section 1232 to the first guide section 121, the limiting section 122, and the connecting guide section 1231, and finally moves from the connecting guide section 1231 back to the initial guide section 1232. The limiting part 31 can slide along the axis of the rotating shaft part 32 after sliding from the initial limiting platform 532 to the first limiting platform 51 due to the contact between the first protrusion 252 and the first abutting member 35. This allows the limiting part 31 to move from the initial limiting platform 532 to the first limiting platform 51, so that the limiting part 31 can then pass through the first guide section 121, the limiting section 122, the connecting guide section 1231 and the initial guide section 1232 in sequence.

[0072] Furthermore, the second limiting platform 52 includes a first step portion 521 and a second step portion 522. The first step portion 521 is connected to the first limiting platform 51. The second step portion 522 is connected to the connecting limiting platform 531. The heights of the first limiting platform 51, the first step portion 521, the second step portion 522, and the connecting limiting platform 531 decrease sequentially.

[0073] It is understood that after the limiting part 31 slides to the first step part 521, it enters the limiting section 122 until the limiting part 31 slides to the second step part 522 and is locked in the limiting section 122. By the height difference between the first step part 521 and the second step part 522, the limiting part 31 is restricted from sliding in the opposite direction in the limiting section 122. In order to lock the limiting part 31 in the second step part 522, the sliding of the push rod 2 is locked.

[0074] Furthermore, the second protrusion 253 includes a bulge 2531, a first protruding edge 2532, and a second protruding edge 2533. The bulge 2531 is disposed at one end of the traction body 251 near the rotating shaft 32, and the first protrusion 252 abuts against the first abutting member 35 only after the bulge 2531 abuts against the second abutting member 36.

[0075] It is understandable that when the first convex 2531 abuts against the first abutting member 35, the convex 2531 abuts against the first abutting member 35, causing the rotating shaft 32 and the limiting part 31 to slide towards the initial limiting platform 532, so that the distance between the limiting part 31 and the initial limiting platform 532 is less than the height difference between the initial limiting platform 532 and the connecting limiting platform 531, so as to restrict the limiting part 31 from sliding in the opposite direction to the connecting limiting platform 531.

[0076] Furthermore, the first protruding edge 2532 and the second protruding edge 2533 are sequentially connected to each other in a direction away from the rotating shaft portion 32. The protrusion height of the second protruding edge 2533 is higher than that of the first protruding edge 2532, and the first protruding edge 2532 abuts against the second abutting member 36 before the second protruding edge 2533.

[0077] It is understood that when the first protruding edge 2532 abuts against the second abutting member 36, the limiting part 31 corresponds to the first step part 521. The distance between the limiting part 31 and the first step part 521 is less than the height difference between the first step part 521 and the initial limiting platform 532, thus restricting the limiting part 31 from sliding in the opposite direction from the first step part 521 to the first limiting platform 51.

[0078] It is worth noting that the height of the first protrusion 2532 and the second protrusion 2533 is less than the height of the convex bulge 2531 on the traction body 251.

[0079] When the second protruding edge 2533 abuts against the second abutting member 36, the limiting part 31 corresponds to the second step part 522. The distance between the limiting part 31 and the second step part 522 is less than the height difference between the second step part 522 and the first step part 521, thus restricting the limiting part 31 from sliding in the opposite direction from the second step part 522 to the first step part 521.

[0080] It should be noted that, in this embodiment, along the sliding direction of the limiting part 31, the height differences between the first guide section 121 to the limiting section 122, the connecting guide section 1231, the initial guide section 1232, the first limiting platform 51, the second limiting platform 52, the connecting limiting platform 531, and the initial limiting platform 532 are all 0.5mm. The distances between the limiting part 31 and the first limiting platform 51, the second limiting platform 52, the connecting limiting platform 531, and the initial limiting platform 532 are all less than 0.5mm. The height of the first protrusion 252 and the protrusion 2531 on the traction body 251 is equal to the distance between the limiting part 31 and each step plus 0.5mm.

[0081] Further reading Figure 1 The push rod 2 also includes a third extension 26. The third extension 26 is connected to the end of the second extension 22 away from the first extension 21. The third extension 26 and the connecting arm 24 are located on opposite sides of the second extension 22.

[0082] Specifically, the third extension segment 26 first extends in a direction perpendicular to the second extension segment 22, and then extends in a direction parallel to the second extension segment 22, so that the third extension segment 26 has two extended parts, that is, the two extended parts of the third extension segment 26 are perpendicular to each other, so that the third extension segment 26 extends in a direction away from the sliding path of the second extension segment 22, so that the second extension segment 22 slides with the first extension segment 21.

[0083] Furthermore, in order to better implement the linkage structure in the embodiments of this application, based on the linkage structure, the embodiments of this application also provide a water dispenser, which includes a body, a button 7, a faucet 6, and a linkage structure as described in any of the above embodiments.

[0084] Button 7 is located on the main body. Faucet 6 is located at the end of the main body away from button 7. A linkage structure is located between button 7 and faucet 6, and connects button 7 and faucet 6 via the linkage structure. The linkage structure is configured such that when the limiting part 31 slides from the first guide section 121 to the limiting section 122, the pull rod 3 pulls the push rod 2, so that faucet 6 is in a locked state that keeps it open; and after the limiting part 31 slides from the limiting section 122 to the second guide section 123, the pull rod 3 releases the push rod 2, so that faucet 6 is unlocked.

[0085] It is understandable that when button 7 is pressed, button 7 drives push rod 2 to slide relative to housing 1, so that the linkage structure presses faucet 6. When the limiting part 31 of pull rod 3 slides from the first guide section 121 to the limiting section 122, pull rod 3 pulls push rod 2 tight, so that faucet 6 remains open. When button 7 is pressed again, button 7 drives push rod 2 to slide, so that the limiting part 31 of pull rod 3 slides from the limiting section 122 to the second guide section 123. After the external force of button 7 is released, the elastic element 4 drives push rod 2 and button 7 to reset.

[0086] It is worth noting that a reset element is also provided inside the faucet 6. The reset element is elastic and configured to drive the faucet 6 to close. The reset element and the elastic element 4 have the same elastic force and stroke.

[0087] Specifically, the reset component includes a reset spring, which is disposed within the switch valve of the faucet 6 and configured to drive the faucet 6 to open and abut against the resetting of the connecting rod structure. It should be noted that the spring force and structure of the reset spring and the elastic element 4 are identical, making the torque of the reset spring close to the torque of the elastic element 4. This facilitates uniform force distribution on the connecting rod during sliding and effectively reduces the frictional force experienced by the connecting rod during sliding.

[0088] This application installs a linkage structure on a water dispenser, utilizing the two-stage pressing displacement of the linkage to achieve continuous water flow with a single press of the faucet 6 and stop water flow with a second press. During the first press, the pull rod 3 locks the linkage; after the second press, the pull rod 3 disengages from the linkage, releasing the lock on the push rod 2. During the sliding of the push rod 2, the limiting part 31 of the pull rod 3 moves within the annular groove 12, and through the anti-reverse structure 5, the limiting part 31 slides unidirectionally along the directions of the first guide section 121, the limiting section 122, and the second guide section 123, ensuring precise locking and release of the push rod 2 by the pull rod 3, thereby improving the accuracy of continuous and stopped water flow control of the water dispenser faucet 6.

[0089] The water dispenser in this embodiment of the application has all the beneficial effects of the aforementioned linkage structure because it is equipped with the linkage structure described above, which will not be repeated here.

[0090] The foregoing has provided a detailed description of a linkage structure and a water dispenser provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
