Description

Technical Field

[0001] This utility model relates to the field of drinking water equipment, and in particular to a water dispenser. Background Technology

[0189] The following is based on Figures 1 to 35 This utility model describes the water dispenser in detail.

[0190] In this embodiment, such as Figure 1 , Figure 12 and Figure 24 As shown, the water dispenser 100 includes a kettle 1, a base assembly 2 and a main unit 3. The kettle 1 is provided with an upper coupler 11. The base assembly 2 includes a support base 21 and a lower coupler 221. The lower coupler 221 is provided on the support base 21. The support base 21 is connected to the main unit 3 through a mounting assembly 4.

[0191] The water dispenser 100 may further include a processor (not shown) and a power module (not shown), with a lower coupler 221 electrically connected to both the processor and the power module. In one embodiment of this application, the lower coupler 221 may be directly electrically connected to the processor and the power module via a wire. In another embodiment of this application, the water dispenser 100 may further include a connecting coupler 222, which is mounted in the support base 21, and the lower coupler 221 is electrically connected to the processor and the power module via the connecting coupler 222.

[0192] like Figure 1 As shown, the mounting assembly 4 includes a moving track 41 and a hinge 42. The moving track 41 is disposed on the main unit 3, and the hinge 42 is movably mounted on the moving track 41. The support base 21 is hinged to the main unit 3 via the hinge 42. The support base 21 can move along the moving track 41 to switch between a working position and a non-working position. Figure 3As shown, when the support base 21 is in the working position, the kettle 1 can be placed on the support base 21 to collect water. The user can place the kettle 1 on the base assembly 2 to collect water, and the lower coupler 221 is electrically connected to the upper coupler 11 of the kettle 1 to supply power to the lower coupler 221. When the user uses a water cup to collect water, because the lower coupler 221 protrudes from the support base 21, the water cup cannot be placed on the support base 21. The user can drive the support base 21 to move along the moving track 41 to move from the working position to the non-working position, such as... Figure 9 and Figure 10 As shown, when the support base 21 is in the non-working position, the user can manually rotate the support base 21 so that the support base 21 is away from the water receiving area, and the user can place the water cup directly on the table.

[0193] In the above technical solution, the water dispenser 100 is equipped with an installation component 4. The support base 21 is mounted to the main unit 3 through the installation component 4, allowing the support base 21 to switch between a working position and a non-working position. Furthermore, when in the non-working position, the support base 21 can rotate away from the water dispensing area, allowing the user to place the water cup directly on the countertop. This allows the water dispenser 100 to have only one water outlet 311, which is beneficial for the miniaturization of the entire machine. Of course, the base component 2 of this solution can also be applied to water dispensers with multiple water outlets.

[0194] In one implementation, such as Figure 1 , Figure 3 and Figure 4 As shown, the main unit 3 includes a main unit housing 31, which has a clearance opening 312. A moving track 41 is located inside the main unit housing 31 to improve the aesthetic appearance of the water dispenser 100. A hinge 42 passes through the clearance opening 312 and is movably mounted on the moving track 41. The contour of the clearance opening 312 restricts the movement direction of the hinge 42, ensuring that the hinge 42 can only move along the extension direction of the moving track 41. Alternatively, the moving track 41 can also be located outside the main unit housing 31.

[0195] Furthermore, such as Figure 6 and Figure 8 As shown, the moving track 41 includes a first guide rail plate 411 and a second guide rail plate 412. The first guide rail plate 411 and the second guide rail plate 412 are arranged opposite to each other to form the moving track 41. The moving track 41 has a simple structure and is easy to process.

[0196] Furthermore, such as Figure 1 and Figure 8As shown, one sidewall of the clearance opening 312 extends toward the interior of the main unit housing 31 to form a first guide rail plate 411, and the other sidewall of the clearance opening 312 extends toward the interior of the main unit housing 31 to form a second guide rail plate 412. The moving track 41 is directly formed on the main unit housing 31 of the main unit 3, simplifying the assembly process. Furthermore, in order to improve the structural strength of the first guide rail plate 411 and the second guide rail plate 412, the bottom wall of the first guide rail plate 411 and the bottom wall of the second guide rail plate 412 are respectively connected to the inner bottom wall of the main unit housing 31.

[0197] In one embodiment, when the support base 21 is in the working position, the support base 21 is limited to the host 3 by the first limiting structure to restrict the support base 21 from moving in the direction away from the host housing 31. At this time, the outer wall of the support base 21 abuts against the outer wall of the host 3, and the outer wall of the host 3 can restrict the support base 21 from moving in the direction toward the host 3, thereby restricting the support base 21 from displacing in the front-back direction.

[0198] Furthermore, the support base 21 is connected to the main unit 3 through the first limiting structure to achieve limiting, which is simple in structure.

[0199] Furthermore, such as Figure 1 , Figure 2 and Figure 9 As shown, the support base 21 has an extension structure 217, and the extension structure 217 has a snap-fit ​​protrusion 2171. The main unit housing 31 of the main unit 3 has an assembly port 316. When the support base 21 is in the working position, the extension structure 217 passes through the assembly port 316 and extends into the main unit housing 31. The snap-fit ​​protrusion 2171 engages with the inner side wall of the main unit housing 31 to restrict the support base 21 from moving away from the main unit housing 31. The snap-fit ​​protrusion 2171 constitutes a first limiting structure. When the support base 21 moves from the working position to the non-working position, the snap-fit ​​protrusion 2171 is squeezed by the assembly port 316, causing the extension structure 217 to deform until the extension structure 217 exits from the assembly port 316. The support base 21 can then smoothly move from the working position to the non-working position.

[0200] To facilitate quick engagement or disengagement of the latching protrusion 2171 with the main unit housing 31, such as... Figure 2 As shown, the extension structure 217 includes a connecting arm 2172 and a hollow part 2173. The hollow part 2173 is C-shaped or U-shaped and is arranged around the connecting arm 2172 so that the connecting arm 2172 has a certain elastic deformation performance. The buckle protrusion 2171 is provided on the connecting arm 2172.

[0201] In one embodiment, when the support base 21 is in a non-working position, the support base 21 is limited to the host 3 by the second limiting structure to restrict the hinge 42 from moving in a direction away from the host housing 31, so as to prevent the hinge 42 and the support base 21 from detaching from the host 3.

[0202] Furthermore, such as Figure 8 As shown, the inner wall of the main unit casing 31 of the main unit 3 is provided with a limiting protrusion 313, which constitutes a second limiting structure, and the structure is simple. Figure 7 As shown, when the support base 21 is in the non-working position, the limiting protrusion 313 restricts the hinge 42 from moving in the direction away from the main unit housing 31, thereby restricting the support base 21 from moving in the direction away from the main unit housing 31.

[0203] Furthermore, such as Figure 4 and Figure 7 As shown, the hinge 42 has an elongated hole 421, into which a limiting protrusion 313 extends. When the support 21 is in a non-working position, the limiting protrusion 313 abuts against one end of the wall of the elongated hole 421 to achieve restriction. A gap is left between the circumferential outer wall of the limiting protrusion 313 and the wall of the elongated hole 421. When the support 21 switches between the working and non-working positions, the elongated hole 421 can be displaced relative to the limiting protrusion 313.

[0204] In one implementation, such as Figure 4 As shown, the limiting protrusion 313 is provided on the inner bottom wall of the main unit housing 31. Of course, the limiting protrusion 313 can also be provided on the inner side wall of the main unit housing 31. The limiting protrusion 313 has a bent structure so as to partially extend into the elongated hole 421, thereby restricting the hinge member 42 from moving away from the main unit housing 31 when the support base 21 is not in the working position.

[0205] In one implementation, such as Figure 3 , Figure 4 and Figure 8 As shown, the main unit housing 31 includes an upper housing 314 and a bottom housing 315. The upper housing 314 and the bottom housing 315 are detachably connected, which facilitates the installation of the internal components of the main unit 3 into the main unit housing 31. The limiting protrusion 313 is provided on the inner wall of the bottom housing 315.

[0206] In one implementation, such as Figures 4 to 7As shown, the limiting protrusion 313 is provided with a threaded hole 3131. The mounting assembly 4 also includes a bolt 43 and a first washer 44. The bolt 43 passes through the first washer 44 and is screwed into the threaded hole 3131. The head of the bolt 43 presses the first washer 44 downward against one side of the outer wall of the elongated hole 421. In this design, one end of the hinge 42 is restricted by the contour of the clearance opening 312, and the other end of the hinge 42 is pressed by the first washer 44, so that the hinge 42 can move stably in the moving track 41 and prevent the hinge 42 from tilting or wobbling.

[0207] In one implementation, such as Figure 1 , Figure 4 , Figure 5 , Figure 9 and Figure 10 As shown, the hinge 42 includes a hinge shaft 422, and the support base 21 is provided with a bushing 219, which is rotatably sleeved on the hinge shaft 422.

[0208] Furthermore, such as Figures 4 to 6 As shown, the hinge 42 includes a hinge portion 423. The hinge portion 423 has a recess 4231 on the side facing the support base 21. The hinge portion 423 also has a first mounting hole 4232 and a second mounting hole 4233. The hinge shaft 422 is a bolt, and a bushing 219 is inserted into the recess 4231. The hinge shaft 422 passes through the first mounting hole 4232, the bushing 219, and the second mounting hole 4233 in sequence and is then locked by a nut 424. In this design, the recess 4231 in the hinge portion 423 can limit the movement of the hinge shaft 422, and the cavity wall of the recess 4231 can restrict the vertical displacement of the hinge shaft 422. Furthermore, configuring the hinge shaft 422 as a bolt structure facilitates quick and easy assembly of the support base 21 with the mounting assembly 4.

[0209] Furthermore, such as Figures 4 to 6 As shown, the mounting assembly 4 includes a second washer 425, a hinge shaft 422 passes through the second washer 425, and the cap of the hinge shaft 422 presses the second washer 425 against the outer wall of the hinge portion 423 to prevent the hinge shaft 422 from moving axially.

[0210] In one implementation, such as Figure 3 As shown, the support base 21 is a water collection box structure, which is used to collect water falling on the upper surface of the support base 21 to prevent water stains from remaining on the surface of the support base 21 during the water collection process.

[0211] In one implementation, such as Figure 3 As shown, the main unit 3 has a water outlet 311, and the support base 21 is located below the water outlet 311. The water dispenser 100 in this solution is equipped with only one water outlet 311, which can realize both the functions of filling a kettle and filling a cup, which is conducive to cost reduction and miniaturization of the whole machine.

[0212] In one implementation, such as Figure 12 As shown, the main unit 3 includes a main unit housing 31 and a raw water tank 32. The support base 21 is located in front of the main unit housing 31, and the raw water tank 32 is located in the rear of the main unit housing 31 to reduce the lateral size of the whole machine.

[0213] In one implementation, such as Figure 11 and Figure 12 As shown, the base assembly 2 also includes a cup holder 23, which is movably connected to the support base 21.

[0214] like Figure 11 and Figure 17 As shown, the cup holder 23 can undergo a first movement relative to the support base 21 to switch between two states: an extended position and a retracted position. The first movement refers to movement in a first direction. Figure 11 and Figure 13 As shown, when the cup holder 23 is in the extended position, the placement surface of the cup holder 23 is higher than the lower coupler 221, that is, the placement surface of the cup holder 23 is higher than the highest point of the lower coupler 221, or the placement surface of the cup holder 23 is flush with the highest point of the lower coupler 221. The placement surface of the cup holder 23 can be used to support the water cup. Preferably, the placement surface of the cup holder 23 is flush with the highest point of the lower coupler 221. This allows it to be used with existing kettles 1 without modifying the structure of the kettle 1, reducing modification costs. Figure 17 and Figure 18 As shown, when the cup holder 23 is in the retracted position, the lower coupler 221 extends at least partially above the cup holder 23 so that the lower coupler 221 can be electrically connected to the upper coupler 11 of the kettle.

[0215] And, as Figure 13 and Figure 14 As shown, when the cup holder 23 is in the extended position, the cup holder 23 can undergo a second movement to switch between a locked state and a free state, wherein the second movement refers to movement in a second direction. Figure 14 As shown, when the cup holder 23 is in the locked state, its movement in the first direction is restricted, preventing it from making the first movement. The cup holder 23 cannot move from the extended position to the retracted position, thus stably supporting the water cup. The user can place the water cup on the cup holder 23 to drink water directly. Figure 13As shown, when the cup holder 23 is in a free state, it can undergo a first movement, moving from the extended position to the retracted position. Thus, when the user places the kettle 1 onto the base assembly 2, the cup holder 23 automatically moves from the extended position to the retracted position under the weight of the kettle 1. The lower coupler 221 of the kettle 1 can achieve structural and electrical connection with the upper coupler 11, allowing the kettle 1 to hold water. After water is stored in the kettle 1, it can further perform functions such as cooking and heat preservation. Of course, the force that drives the cup holder 23 from the extended position to the retracted position is not limited to the weight of the kettle 1; it can also be manual pressing, an automatic drive mechanism configured in the base assembly 2, or a combination of several forces.

[0216] In the above technical solution, by configuring a cup holder 23 on the support base 21 and defining the assembly relationship between the cup holder 23 and the support base 21, the cup holder 23 has three positions: an extended position in a locked state, an extended position in a free state, and a retracted position. This allows the base assembly 2 to simultaneously support the kettle 1 and be electrically connected to it, as well as support the cup. When the user fills the cup with water, the user can choose to pull out and rotate the support base 21 away from the water-filling area, or use the cup holder 23 to support the cup. In this way, the water dispenser 100 can be equipped with only one water outlet 311, which is beneficial for the miniaturization of the entire machine. Of course, the base assembly 2 of this solution can also be applied to water dispensers with multiple water outlets.

[0217] The following text uses the example of "when the cup holder 23 is in the extended position, the placement surface of the cup holder 23 is flush with the highest point of the lower coupler 221" for a detailed explanation.

[0218] In one implementation, such as Figure 11 , Figure 12 and Figure 17 As shown, the first movement is a vertical movement, i.e., the first direction is vertical. Thus, when the cup holder 23 is in its extended, free state, placing the kettle 1 on the base assembly 2 causes the kettle 1 to press the cup holder 23 downwards. The cup holder 23 moves downwards until its placement surface is flush with the placement surface of the support base 21. The cup holder 23 then switches to its retracted position, where its placement surface supports the kettle, or both the placement surface of the cup holder 23 and the placement surface of the support base 21 jointly support the kettle. At this time, the upper coupler 11 and the lower coupler 221 are electrically connected. When the kettle 1 is removed, the cup holder 23 moves upwards to its extended position under external force.

[0219] In one implementation, such as Figures 11 to 16 As shown, the second motion is a rotational motion about the central axis of the cup holder 23, that is, the second direction is the direction of rotation about the central axis of the cup holder 23. When the cup holder 23 is in the extended position, the cup holder 23 can rotate under external force (such as manual rotation) to switch between a locked state and a free state.

[0220] Furthermore, the cup holder 23 rotates at an angle of 10°-20° when switching between the locked and free states, and the switching is rapid. Preferably, the rotation angle is 15°.

[0221] In one implementation, such as Figure 11 , Figure 13 and Figure 21 As shown, the cup holder 23 is arranged around the lower coupler 221. Specifically, the cup holder 23 has an annular cavity 237 in the middle, and the lower coupler 221 is at least partially located in the annular cavity 237. The size of the upper opening of the annular cavity 237 is as small as possible, so that when the user places the cup on the base assembly 2, the cup holder 23 can provide stable support for the cup and prevent the weight of the cup from being concentrated too much on the lower coupler 221. Of course, the circumferential outer contour of the cup holder 23 can be a regular shape such as a circle or a square ring, or it can be an irregular shape. Preferably, in order to simplify the structure of the cup holder 23 and facilitate the assembly of the cup holder 23 and the support base 21, the circumferential outer contour of the cup holder 23 and the shape of the annular cavity 237 are both circular.

[0222] In one implementation, such as Figure 11 and Figure 13 As shown, the support base 21 is provided with a water collection hole 2111 and a water collection cavity 2112 that are connected. The water collection hole 2111 is located on the top wall of the support base 21. In this way, when water is collected by the kettle 1 or the cup, if water overflows, it can be collected through the water collection cavity 2112 to prevent water stains from remaining on the table surface of the water dispenser 100.

[0223] Furthermore, such as Figure 13 , Figure 15 and Figure 19 As shown, the support base 21 has an annular mounting portion 212, and the lower coupler 221 is installed in the annular mounting portion 212 with an interference fit. The water collection cavity 2112 is arranged around the annular mounting portion 212. A sealing element 24 is provided between the lower coupler 221 and the annular mounting portion 212. The sealing element 24 is used to prevent water in the water collection cavity 2112 from entering the annular mounting portion 212, thereby avoiding affecting the service life of the lower coupler 221.

[0224] Furthermore, such as Figure 12 , Figure 13 and Figure 23As shown, the water dispenser also includes a drain trough 25, which is connected to the support base 21 and located below the annular mounting portion 212. The drain trough 25 communicates with the bottom port of the annular mounting portion 212. When water flows through the structural gap of the lower coupler 221 and enters the annular mounting portion 212, the water is discharged to the outside through the drain chamber 253 of the drain trough 25, preventing water from accumulating in the annular mounting portion 212 and affecting the service life of the lower coupler 221.

[0225] Furthermore, such as Figure 23 As shown, the bottom wall of the drainage trough 25 is provided with a drain outlet 251, and the inner bottom wall of the drainage trough 25 is provided with a blocking structure 252. The blocking structure 252 covers the drain outlet 251, and an opening 2521 is provided on one vertical side of the blocking structure 252. The opening 2521 communicates with the drain outlet 251 to form a discharge channel for draining water outward. By configuring the blocking structure 252, the drainage trough 25 changes the path from the drain outlet 251 to the drainage chamber 253, thereby preventing external foreign objects from entering the drainage chamber 253 of the drainage trough 25.

[0226] Furthermore, such as Figure 20 and Figure 23 As shown, the annular mounting part 212 is provided with a positioning post 2121, and the drainage trough body 25 is provided with a positioning groove 254. When assembling the support base 21 and the drainage trough body 25, the positioning post 2121 and the positioning groove 254 are aligned first, and then assembled. The positioning post 2121 and the positioning groove 254 cooperate to play a role in positioning and pre-assembly, which facilitates quick assembly. Figure 13 and Figure 23 As shown, the drainage trough 25 is provided with snap-fit ​​ribs 255, which snap-fit ​​with the bottom opening of the annular mounting part 212 to achieve quick pre-installation. Then, the support base 21 and the drainage trough 25 are fixed by fasteners (such as bolts).

[0227] In one implementation, such as Figure 13 As shown, when the cup holder 23 is in the extended position, the bottom of the cup holder 23 is located inside the support base 21. Figure 18 As shown, when the cup holder 23 is in the retracted position, the cup holder 23 is completely located within the support base 21, and the placement surface of the cup holder 23 is flush with the placement surface of the support base 21. In this design, the internal space of the support base 21 is used to provide room for the first movement of the cup holder 23. Furthermore, when the cup holder 23 is in the retracted position, the placement surface of the cup holder 23 is flush with the placement surface of the support base 21. In this way, the placement surface of the cup holder 23 and the placement surface of the support base 21 (e.g., the upper surface) cooperate to support the kettle 1, which facilitates the stable placement of the kettle 1.

[0228] In one implementation, such as Figures 13 to 16As shown, the water dispenser 100 also includes an elastic element 26, which abuts against the support base 21 and the cup holder 23 respectively. Figure 18 As shown, when the cup holder 23 moves to the retracted position under external force, the elastic element 26 is compressed and stores energy. Figure 13 As shown, when the external force is removed, the elastic element 26 rebounds, and the elastic element 26 drives the cup holder 23 to make a first movement to the extended position. In addition, the elastic element 26 is also used to keep the cup holder 23 in the extended position in a free state.

[0229] Furthermore, such as Figure 12 , Figure 13 and Figure 17 As shown, the cup holder 23 moves to the retracted position under the weight of the kettle 1. The weight of the kettle 1 when it is unloaded is greater than the elastic force of the elastic element 26. Thus, when the kettle 1 is placed on the base assembly 2, the kettle 1 can press the cup holder 23 down from the extended position to the retracted position. The operation is convenient and does not require additional force.

[0230] In one implementation, such as Figure 13 , Figure 15 and Figure 19 The support base 21 is provided with a clearance through hole 2131 and an abutment portion 2132, the cup holder 23 is provided with a limiting post 231, and the elastic member 26 is sleeved on the outer periphery of the limiting post 231. Figure 13 and Figure 15 As shown, when the cup holder 23 is in the extended position in its free state, the limiting post 231 is located outside the clearance through hole 2131 and aligned with the clearance through hole 2131 of the limiting post 231. Thus, as... Figure 18 As shown, when the cup holder 23 undergoes its first movement under external force, the limiting post 231 inserts into the clearance through hole 2131, allowing the cup holder 23 to switch from the extended position to the retracted position. Figure 14 and Figure 16 As shown, when the cup holder 23 is in the extended position in the free state, an external force drives the cup holder 23 to undergo a second movement to the locked state. When the cup holder 23 undergoes the second movement, the limiting post 231 also undergoes a second movement simultaneously. At this time, the abutting part 2132 abuts against the limiting post 231 to restrict the limiting post 231 from undergoing the first movement, thereby restricting the cup holder 23 from undergoing the first movement to the retracted position, so as to ensure that the cup holder 23 can be stably maintained in the extended position.

[0231] Furthermore, such as Figure 13 As shown, when the cup holder 23 is in the extended position in its free state, the clearance hole 2131 is located directly below the limiting post 231. Thus, the cup holder 23, in its extended position, moves downwards to the retracted position under the weight of the kettle 1. Figure 13 and Figure 15As shown, the upper end of the clearance through hole 2131 is located on the abutment portion 2132, and one end of the elastic member 26 abuts downward against the abutment portion 2132. Figures 13 to 16 As shown, when the cup holder 23 is rotated, the limiting post 231 first moves away from above the clearance through hole 2131, and then the bottom wall of the limiting post 231 slides along the surface of the abutment portion 2132 until the cup holder 23 rotates to the locked position. The external force is then removed. At this point, because the bottom wall of the limiting post 231 abuts against the surface of the abutment portion 2132, it ensures that the cup holder 23 cannot move downwards to the retracted position. Furthermore, since the elastic member 26 is sleeved on the outer periphery of the limiting post 231 and rotates with the limiting post 231, the diameter of the end of the elastic member 26 that abuts against the abutment portion 2132 must be larger than the diameter of the clearance through hole 2131 to prevent the elastic member 26 from getting stuck in the clearance through hole 2131 during rotation, thus affecting the normal use of the cup holder 23.

[0232] Furthermore, the elastic element 26 is a tower-shaped spring, with its small-diameter end abutting upward against the cup holder 23 and its large-diameter end abutting downward against the abutment portion 2132. The tower-shaped spring is compact yet has a large load capacity. Of course, the elastic element 26 can also be a cylindrical spring.

[0233] In one implementation, such as Figure 13 , Figure 14 , Figure 19 and Figure 21 As shown, the support base 21 is provided with a first fastening structure 214, and the cup holder 23 is provided with a second fastening structure 234. When the cup holder 23 is in the extended position (including the free state and the locked state), the first fastening structure 214 and the second fastening structure 234 are fastened together to restrict the cup holder 23 from moving in a direction away from the support base 21. Specifically, as... Figure 13 As shown, when the cup holder 23 is in its extended, free position, the cup holder 23 cannot move upwards because the first fastening structure 214 and the second fastening structure 234 are engaged, preventing the cup holder 23 from detaching from the support base 21. When a kettle 1 needs to be placed on it, the cup holder 23 can move downwards to its retracted position under external force. Figure 14 As shown, when the cup holder 23 is in the extended position of the locked state, the cup holder 23 cannot move upward or downward in order to support the water cup.

[0234] Furthermore, such as Figure 15 and Figure 19 As shown, the first fastening structure 214 includes a connected vertical rib 2141 and a fastening part 2142, with the vertical rib 2141 protruding from the bottom inner wall of the support base 21. Figure 21 As shown, the second fastening structure 234 is a protruding structure protruding from the inner wall of the cup holder 23, such as... Figure 13 and Figure 15As shown, the second fastening structure 234 is located below the fastening part 2142. When the cup holder 23 is in the extended position, the fastening part 2142 abuts against the second fastening structure 234 downwards to prevent the cup holder 23 from moving upwards.

[0235] Furthermore, the second motion is a rotational motion about the central axis of the cup holder 23, such as... Figure 19 As shown, the vertical rib 2141 is bent on both sides to form limiting arms 21411. The second fastening structure 234 is located between the two limiting arms 21411. The two limiting arms 21411 are used to limit the movement path of the second fastening structure 234, thereby limiting the maximum rotation angle of the cup holder 23. For example, the maximum rotation angle of the cup holder 23 can be limited to 10°-20°, which is beneficial for the cup holder 23 to quickly switch between the free state and the locked state. Specifically, when the cup holder 23 is in the extended position of the free state, the second fastening structure 234 abuts against one of the limiting arms 21411; when the cup holder 23 is in the extended position of the locked state, the second fastening structure 234 abuts against the other limiting arm 21411. By limiting the distance between the two limiting arms 21411, the maximum rotation angle of the cup holder 23 can be limited.

[0236] Furthermore, such as Figure 19 As shown, the fastening part 2142 includes a first fastening protrusion 21421 and a second fastening protrusion 21422 arranged sequentially along the rotation direction of the cup holder 23. The vertical rib 2141 has two notches 21412, and a spring arm 21413 is formed between the two notches 21412. The first fastening protrusion 21421 is connected to the spring arm 21413, as shown. Figure 13 and Figure 19As shown, when the cup holder 23 is in a free state, the first fastening protrusion 21421 is fastened to the second fastening structure 234. Specifically, when assembling the cup holder 23 and the support base 21, since the two sides of the vertical rib 2141 bend to form a limiting arm 21411, if in the initial stage of assembly, the first fastening structure 214 and the second fastening structure 234 are first distributed sequentially along the rotation direction of the cup holder 23, and then the cup holder 23 is rotated so that the second fastening structure 234 rotates to be located below the fastening part 2142 to achieve the fastening of the two, this assembly method, due to the presence of the limiting arm 21411, interferes with the rotation of the second fastening structure 234, increasing the assembly difficulty and requiring more effort. Therefore, the fastening part 2142 is set as follows: The first snap-fit ​​protrusion 21421 and the second snap-fit ​​protrusion 21422 are two separate snap-fit ​​protrusions. The first snap-fit ​​protrusion 21421 is connected to the spring arm 21413. Thus, when assembling the cup holder 23 and the support base 21, the second snap-fit ​​structure 234 is first aligned with the first snap-fit ​​protrusion 21421, and then the cup holder 23 is pressed down. The second snap-fit ​​structure 234 compresses the first snap-fit ​​protrusion 21421, and the spring arm 21413 deforms due to the force, allowing the second snap-fit ​​structure 234 to smoothly engage with the first snap-fit ​​protrusion 21421. After assembly, the cup holder 23 is in a free, extended position. Figure 14 and Figure 19 As shown, if the cup holder 23 is rotated to the locked state, the second fastening structure 234 rotates to engage with the second fastening protrusion 21422. In addition, in this design, the spring arm 21413 is only configured on the first fastening protrusion 21421, which ensures that the vertical rib 2141 has a certain structural strength and facilitates the assembly of the cup holder 23.

[0237] Furthermore, such as Figure 19 As shown, the outer wall of the spring arm 21413 is connected with reinforcing ribs 21414 to improve the structural strength of the spring arm 21413.

[0238] In one implementation, such as Figure 13 , Figure 15 and Figure 21 As shown, the second fastening structure 234 is a protrusion protruding from the inner wall of the cup holder 23. When the cup holder 23 is in the extended position, the abutting part 2132 of the support post 213 is located below the second fastening structure 234, and the lower end face of the limiting post 231 is located below the second fastening structure 234. Of course, when the cup holder 23 is in the extended position, the positional relationship between the lower end face of the limiting post 231 and the second fastening structure 234 is not limited to this. For example, if the abutting part 2132 of the support post 213 is located above the second fastening structure 234, then the lower end face of the limiting post 231 must be located above the second fastening structure 234.

[0239] In one implementation, such as Figure 15 , Figure 19 and Figure 21 As shown, there are three of each of the following: clearance through-hole 2131, abutment portion 2132, elastic element 26, and limiting post 231. The three limiting posts 231 are spaced apart along the rotation direction of the cup holder 23. The clearance through-hole 2131, abutment portion 2132, and elastic element 26 are respectively provided in a one-to-one correspondence with the limiting post 231 to provide stability for the assembly of the cup holder 23 and the support base 21. Furthermore, there are also three first fastening structures 214. The support post 213 and the first fastening structure 214 are alternately distributed along the rotation direction of the cup holder 23, arranged compactly. Of course, the number of each of the following structures is not limited to three: clearance through-hole 2131, abutment portion 2132, elastic element 26, limiting post 231, and first fastening structure 214. There can also be two, four, or even more.

[0240] In one implementation, such as Figure 19 As shown, the upper surface of the support column 213 forms an abutment part 2132, which has a simple structure.

[0241] Furthermore, such as Figure 13 , Figure 15 and Figure 19 As shown, the upper surface of the support column 213 is provided with annular ribs 2133, and the lower end of the limiting column 231 and the lower end of the elastic member 26 are respectively inserted into the annular ribs 2133. The annular ribs 2133 are used to limit the movement path length of the limiting column 231, so as to limit the maximum rotation angle of the cup holder 23. For example, the maximum rotation angle of the cup holder 23 can be limited to 10°-20°, which is conducive to the cup holder 23 quickly switching between the free state and the locked state. Preferably, the vertical rib 2141 of the support base 21 is equipped with two limiting arms 21411, and the support column 213 of the support base 21 is equipped with annular ribs 2133. The support base 21 limits the movement length of the second fastening structure 234 by the two limiting arms 21411, and also limits the movement length of the limiting column 231 by the annular ribs 2133, so as to more stably limit the maximum rotatable angle of the cup holder 23. It should be understood that due to the processing of parts, the limiting actions of the two limiting arms 21411 on the second fastening structure 234 and the limiting actions of the annular ribs 2133 on the limiting column 231 may not occur simultaneously. As long as either of the limiting actions is effective, the maximum rotatable angle of the cup holder 23 can be limited.

[0242] In one implementation, such as Figure 14 and Figure 20 As shown, the support column 213 has a recessed portion 2134 on the side facing away from the cup holder 23 to reduce its own weight, thereby reducing the weight of the base assembly 2.

[0243] In one implementation, such as Figure 13 and Figure 22 As shown, the support base 21 is provided with an annular mounting channel 215, and the cup holder 23 can be movably inserted into the annular mounting channel 215, which has a simple structure.

[0244] Furthermore, such as Figures 11 to 15 As shown, the support base 21 includes a base body 2161 and a cover body 2162. The cover body 2162 is placed on the base body 2161, and the cover body 2162 and the base body 2161 together form a water collection cavity 2112. The upper surface of the cover body 2162 is provided with a recessed portion 21622, and a water collection hole 2111 is provided in the recessed portion 21622. When it is necessary to pour out the water in the water collection cavity 2112, the cover body 2162 can be opened to quickly pour out the water. Figure 15 and Figure 22 As shown, the cover 2162 is provided with a mounting hole 21621, and an annular mounting channel 215 is formed between the hole wall of the mounting hole 21621 and the outer wall of the annular mounting part 212 of the base 2161.

[0245] Furthermore, such as Figure 22 As shown, the annular installation channel 215 is connected to the water collection cavity 2112, which helps to increase the volume of the water collection cavity 2112.

[0246] Furthermore, such as Figure 13 As shown, the support column 213 and the first fastening structure 214 are both located in the water collection cavity 2112. The outer wall of the support column 213 will separate the through hole 2131 from the water collection cavity 2112, so as to avoid the water accumulation in the water collection cavity 2112 from interfering with the switching of the cup holder 23 between the extended position and the retracted position.

[0247] In one implementation, such as Figure 13 and Figure 21As shown, the cup holder 23 is provided with a first annular arm 232 and a second annular arm 233. The first annular arm 232 is located inside the second annular arm 233. The first annular arm 232 and the second annular arm 233 are spaced apart and form an annular groove. The limiting post 231 is located in the annular groove. The first fastening structure 214 is opposite to the annular groove in the vertical direction. The second fastening structure 234 is located in the annular groove. When the cup holder 23 is in the extended position, the fastening part 2142 is located in the annular groove, and the vertical rib 2141 is mostly located below the annular groove. Specifically, since the cup holder 23 needs to move in the vertical direction to switch between the extended and retracted positions, the cup holder 23 needs to have a certain size in the vertical direction (the direction of the first movement). An annular groove is provided on the cup holder 23, and the limiting post 231 is set in the annular groove. When the cup holder 23 moves downward, the support post 213 and the vertical rib 2141 of the support base 21 will extend into the annular groove. When the cup holder 23 is in the retracted position, the support post 213 and the vertical rib 2141 are all or most of the way located in the annular groove. In this way, the internal space of the cup holder 23 in the vertical direction is fully utilized, which helps to reduce the size of the base assembly 2 in the vertical direction. This allows for an increase in the distance between the base assembly 2 and the water outlet 311 of the main unit 3 to accommodate taller kettles and cups. In addition, the annular groove can also reduce the weight of the cup holder 23, thereby reducing the load on the elastic member 26.

[0248] Furthermore, such as Figure 19 and Figure 21 As shown, there are three support columns 213 and three limiting columns 231. The three support columns 213 are spaced apart along the rotation direction of the cup holder 23, and the support columns 213 and limiting columns 231 are matched one-to-one to improve the stability of the cup holder 23 during use. Three connecting ribs 235 are provided between the first annular arm 232 and the second annular arm 233. The three connecting ribs 235 divide the annular groove to form three receiving slots 236. The limiting columns 231 are correspondingly received in the receiving slots 236. By configuring the connecting ribs 235 between the first annular arm 232 and the second annular arm 233, the structural strength of the cup holder 23 can be improved. Of course, the number of each structure, including the support columns 213, limiting columns 231, and connecting ribs 235, is not limited to three; there can also be two, four, or even more.

[0249] Furthermore, there are three of each of the first fastening structure 214 and the second fastening structure 234. The first fastening structure 214 and the support column 213 are arranged alternately along the rotation direction of the cup holder 23. The first fastening structure 214 and the receiving groove 236 are arranged one-to-one in the vertical direction. Each receiving groove 236 accommodates one second fastening structure 234. When the cup holder 23 moves downward, the first fastening structure 214 extends into the matching receiving groove 236 one by one.

[0250] In one embodiment, the support base 21 is detachably connected to the main unit 3, so that when the water cup is too high to be placed on the cup holder 23, the support base 21 can be removed and the water cup can be placed directly on the table (such as a desktop).

[0251] In one implementation, such as Figures 26 to 35 As shown, the base assembly 2 also includes a lifting assembly 27, which includes a linkage 271 and an actuator 272. The linkage 271 includes a connecting part 2711, which is rotatably connected to the support base 21. The linkage 271 is linked with the lower coupler 221.

[0252] like Figure 30 , Figure 31 , Figure 33 and Figure 34 As shown, when the actuator 272 moves, the actuator 272 drives the linkage 271 to rotate, thereby causing the linkage 271 to switch between the lifting state and the lowering state.

[0253] like Figure 34 and Figure 35 As shown, when the linkage 271 switches from the retracted state to the raised state, the linkage 271 drives the lower coupler 221 to move from the retracted position to the extended position. At this time, the lower coupler 221 is at least partially located above the placement surface of the support base 21. When the kettle 1 is placed on the placement surface of the support base 21, the lower coupler 221 can achieve structural and electrical connection with the upper coupler at the bottom of the kettle 1. The lower coupler 221 is electrically connected to the connecting coupler so that the kettle 1 can be electrically connected to the host (the processor and power module are set on the host). After the kettle 1 is filled with water, it can further perform functions such as cooking and keeping warm.

[0254] like Figure 25 and Figure 27 As shown, when the linkage 271 switches from the raised state to the lowered state, the lower coupler 221 can move from the extended position to the retracted position. At this time, the placement surface of the support base 21 is higher than the highest point of the lower coupler 221. Thus, the placement surface of the support base 21 can be used to support the water cup. Alternatively, at this time, the placement surface of the support base 21 is flush with the highest point of the lower coupler 221. Thus, the placement surface of the support base 21 and the lower coupler 221 can jointly support the water cup. The user can place the water cup stably on the base assembly 2 for direct drinking water.

[0255] In the above technical solution, the base assembly 2 is equipped with a lifting component 27, which is configured with a cooperating linkage 271 and an actuator 272. This allows the linkage 271 to switch between a raised state and a lowered state. Simultaneously, since the linkage 271 is linked with the lower coupler 221, the linkage 271 enables the lower coupler 221 to switch between an extended position and a retracted position. Ultimately, the base assembly 2 simultaneously serves the dual functions of supporting the kettle and connecting it electrically, as well as supporting the water cup. This allows the water dispenser 100 to have only one water outlet, facilitating a miniaturized design. Of course, the base assembly 2 of this solution can also be applied to water dispensers with multiple water outlets.

[0256] It should be understood that, usually during the process of placing the kettle, such as Figure 24 As shown, the upper coupler of kettle 1 is inserted into the lower coupler 221 vertically downwards, therefore, as Figure 27 and Figure 34 As shown, the lower coupler 221 moves along the vertical direction to switch between an extended position and a retracted position.

[0257] In one implementation, such as Figure 30 , Figure 31 , Figure 33 and Figure 34 As shown, the linkage 271 also includes a driven part 2712 spaced apart from the connecting part 2711. When the actuator 272 moves, the actuator 272 cooperates with the driven part 2712, causing the linkage 271 to rotate around the rotational connection between the connecting part 2711 and the support base 21, thereby switching the linkage 271 between the lifting state and the lowering state.

[0258] In one implementation, such as Figure 25 , Figure 27 , Figure 30 and Figure 35 As shown, the rotation axis of the connecting part 2711 is perpendicular to the movement direction of the lower coupler 221, which helps to increase the movement distance of the driven part 2712 in the movement direction of the lower coupler 221. This helps to ensure that the linkage 271 can meet the design requirements of the lifting and falling amplitude while minimizing the rotation angle of the linkage 271.

[0259] In one implementation, such as Figure 31 and Figure 34 As shown, when the actuator 272 pushes the driven part 2712 upward, the linkage 271 rotates to switch from the lowered state to the raised state. When the actuator 272 withdraws the upward pushing force, the linkage 271 rotates to switch from the raised state to the lowered state.

[0260] Furthermore, such as Figure 31 and Figure 34 As shown, when the actuator 272 withdraws its upward lifting force, the linkage 271 rotates under the gravity of the linkage 271 and the lower coupler 221, switching from the lifted state to the lowered state, thus simplifying the cooperation structure between the actuator 272 and the driven part 2712. Of course, when the actuator 272 withdraws its upward lifting force, the linkage 271 can also switch from the lifted state to the lowered state by the actuator 272. For example, the actuator 272 is the extension rod of a cylinder (not shown in the figure). The actuator 272 is connected to the driven part 2712. When the actuator 272 extends upward, it lifts the linkage 271; when the actuator 272 retracts downward, it pulls the linkage 271 back.

[0261] In one implementation, such as Figure 29 and Figure 30 As shown, the lower coupler 221 includes a coupling electronic component 2211 and a mounting component 2212. The coupling electronic component 2211 is mounted on the mounting component 2212 and is used for electrical connection with the upper coupler. The mounting component 2212 is linked with the linkage component 271, and the mounting component 2212 and the coupling electronic component 2211 are sealed by a sealing ring 2213. By adding the mounting component 2212, the linkage component 271 is prevented from directly linking with the coupling electronic component 2211, thus avoiding damage to the coupling electronic component 2211 due to prolonged localized concentrated stress.

[0262] In one implementation, such as Figures 27 to 31 As shown, the linkage 271 also includes a linkage part 2713, which is used to link with the lower coupler 221. The linkage part 2713 is located between the connecting part 2711 and the driven part 2712, which helps to increase the distance between the connecting part 2711 and the driven part 2712. In this way, by increasing the lever arm, the actuator 272 can more easily lift the linkage 271. Of course, the location of the linkage part 2713 is not limited to this; the driven part 2712 can also be located between the connecting part 2711 and the linkage part 2713.

[0263] In one implementation, such as Figures 26 to 27 As shown, the support base 21 includes a base body 2161 and a cover body 2162. The cover body 2162 covers the base body 2161, and the two together form a cavity 218. The lifting assembly 27 is disposed in the cavity 218. The support base 21 is designed as a split structure to facilitate the quick assembly of the lifting assembly 27.

[0264] Furthermore, such as Figure 28As shown, the bottom wall of the seat 2161 is recessed to form a first recessed structure 21611. The lifting component 27 is partially located within the first recessed structure 21611. Setting the bottom wall of the seat 2161 to have an uneven structure not only accommodates the lifting component 27 but also facilitates the miniaturization of the support seat 21. Alternatively, the lifting component 27 can be entirely located within the first recessed structure 21611. When the linkage 271 is in the lowered state, the lower coupler 221 can be partially located within the first recessed structure 21611 or entirely located outside the first recessed structure 21611.

[0265] In one implementation, such as Figure 28 As shown, one side wall of the seat 2161 is recessed to form a second recessed structure 21612. One side of the lifting component 27 is located in the second recessed structure 21612. Setting one side wall of the seat 2161 to be an uneven structure not only accommodates the lifting component 27, but also facilitates the miniaturization design of the support seat 21.

[0266] In one implementation, such as Figure 26 and Figure 28 As shown, the top of the seat 2161 has a first opening 21613, and one side of the seat 2161 has a second opening 21614. These two openings on the seat 2161 facilitate the assembly of the lifting component 27 into the cavity 218. Preferably, the top of the seat 2161 is completely open, and the side of the seat 2161 with the second opening 21614 is also completely open, providing the operator with a more convenient operating space. Figure 26 and Figure 25 As shown, the cover 2162 has a bent structure to close the first opening 21613 and the second opening 21614.

[0267] In one implementation, such as Figure 26 and Figure 28 As shown, the seat 2161 is provided with a support rib 21615, which is partially located in the first concave structure 21611, and the connecting part 2711 is rotatably connected to the support rib 21615. Of course, the support rib 21615 can also be entirely located in the first concave structure 21611.

[0268] Furthermore, such as Figure 26 and Figure 28As shown, there are two support ribs 21615, and the connecting part 2711 is a shaft structure, which is rotatably connected to the two support ribs 21615 respectively. The top wall of the support rib 21615 has a locking hole 216151, and the connecting part 2711 is engaged downward in the two locking holes 216151 with a clearance fit. Of course, the assembly structure of the support rib 21615 and the connecting part 2711 is not limited to this. The support rib 21615 may also have a circular hole (not shown in the figure), and the connecting part 2711 passes through the two circular holes with a clearance fit between the connecting part 2711 and the hole wall.

[0269] Furthermore, such as Figure 28 As shown, the support rib 21615 gradually expands in the downward direction to improve the structural stability of the support rib 21615.

[0270] In one implementation, such as Figure 30 and Figure 33 As shown, the lower coupler 221 abuts downward against the linkage 271. Thus, when the linkage 271 switches from the lowered state to the raised state, the linkage 271 raises the lower coupler 221; when the linkage 271 switches from the raised state to the lowered state, the linkage 271 moves downward to the retracted position under its own weight and the weight of the lower coupler 221.

[0271] Furthermore, such as Figure 30 and Figure 33 As shown, the lower coupler 221 abuts against the upper surface of the linkage 2713. When the linkage 271 switches between the falling state and the lifting state, the linkage 2713 and the lower coupler 221 remain in contact. Since the lower coupler 221 moves linearly in the up and down direction, in order to prevent the linkage 2713 from getting stuck with the lower coupler 221 during rotation, the linkage 2713 is allowed to slide relative to the lower coupler 221 so that the linkage 271 can rotate smoothly.

[0272] In one implementation, such as Figure 26 , Figure 25 , Figure 27 and Figure 35 As shown, the support base 21 is provided with a third mounting hole 21623, through which the lower coupler 221 passes. The third mounting hole 21623 is configured to guide the lower coupler 221 to move linearly in the vertical direction, ensuring that the lower coupler 221 can only move linearly in the vertical direction. Furthermore, the third mounting hole 21623 is located on the cover 2162. By restricting the movement trajectory of the lower coupler 221 through the third mounting hole 21623, it is ensured that the lower coupler 221 can accurately switch between the extended and retracted positions.

[0273] In one implementation, such as Figure 27 and Figure 29 As shown, the linkage 2713 has an elongated hole 27131, the length of which extends along a first direction a, which is perpendicular to the rotation axis of the connecting part 2711. The lower coupler 221 has an extension post 22121, which is inserted into the elongated hole 27131. When the linkage 271 rotates, the elongated hole 27131 can move relative to the extension post 22121. The elongated hole 27131 restricts the displacement of the extension post 22121 in the extension direction of the rotation axis of the connecting part 2711, which is beneficial for the lower coupler 221 to stably switch between the extended position and the retracted position.

[0274] Furthermore, such as Figure 29 As shown, the elongated hole 27131 is an oblong hole, and the extension post 22121 is a cylinder. When the linkage 271 moves to the point where the end of either end of the elongated hole 27131 contacts the extension post 22121, the contact area between the two can be increased to improve the stability of the limit.

[0275] Furthermore, such as Figure 29 and Figure 30 As shown, the lower coupler 221 has an abutment protrusion 22122, which is connected to the circumferential surface wall of the extension post 22121. The abutment protrusion 22122 abuts downward against the upper surface of the linkage part 2713, as shown. Figure 33 and Figure 34 As shown, when the linkage 271 is in the lifted state, the linkage part 2713 pushes upward to abut against the protrusion 22122, so that the lower coupler 221 is in the extended position; as Figure 30 and Figure 31 As shown, when the linkage 271 switches from the raised state to the lowered state, the abutment protrusion 22122 and the linkage part 2713 remain in contact, and the lower coupler 221 moves downward to the retracted position. Preferably, the lower surface of the abutment protrusion 22122 extends horizontally, and when the linkage 271 is in the lowered state, the upper surface of the linkage part 2713 extends horizontally, so that the linkage part 2713 can more stably support the abutment protrusion 22122.

[0276] Furthermore, such as Figure 29 and Figure 30 As shown, there are two abutment protrusions 22122. The two abutment protrusions 22122 are evenly spaced apart along the circumference of the extension post 22121. In this way, the lower coupler 221 is subjected to balanced force, which is conducive to the lower coupler 221 switching more stably between the extended position and the retracted position.

[0277] In one implementation, such as Figure 29 and Figure 30As shown, the extension column 22121 and the abutment protrusion 22122 are both provided on the mounting member 2212, so that the lower coupler 221 is linked with the linkage member 271 through the mounting member 2212.

[0278] In one implementation, such as Figure 27 , Figure 29 and Figure 30 As shown, the linkage 271 includes a linkage part 2713, a first lever arm 2714 and a second lever arm 2715. A connecting part 2711 is provided on the first lever arm 2714, and a driven part 2712 is provided on the second lever arm 2715. The first lever arm 2714, the linkage part 2713 and the second lever arm 2715 are connected in sequence to form a space 2716. The space 2716 is used to accommodate all or part of the lower coupler 221, which is beneficial to reduce the size of the base assembly 2 in the vertical direction.

[0279] Furthermore, such as Figure 29 and Figure 30 As shown, the linkage 2713 is located below the middle of the first lever arm 2714 and the second lever arm 2715. One end of the linkage 2713 is connected to the first lever arm 2714 and the included angle between the two is an obtuse angle. The other end of the linkage 2713 is connected to the second lever arm 2715 and the included angle between the two is an obtuse angle. This helps to increase the size of the space 2716 so that more couplers 221 can be accommodated.

[0280] In one implementation, such as Figure 29 , Figure 30 , Figure 33 and Figure 34 As shown, the actuator 272 rotates to trigger the linkage 271 to rotate around the rotational connection between the connecting portion 2711 and the support base 21. Of course, the actuator 272 can also move linearly to trigger the linkage 271 to rotate around the rotational connection between the connecting portion 2711 and the support base 21; for example, the actuator 272 can be the extension rod of a cylinder.

[0281] In one implementation, such as Figure 27 and Figure 29 As shown, the lifting assembly 27 also includes a motor, which is located in the motor housing 274. The output shaft 273 of the motor extends out of the motor housing 274 to be coaxially connected with the actuator 272.

[0282] Of course, the structure of the lifting assembly 27 is not limited to this. In other embodiments (not shown in the figure), the lifting assembly 27 may include a motor, the output shaft of which directly constitutes the actuator. The linkage also includes a linkage part and a driven part, which are distributed sequentially. The centerlines of the connecting part and the driven part coincide. The linkage part is a cam structure, and its surface has a raised surface and a recessed surface. The linkage part abuts upward against the lower coupler 221. When the actuator moves, the driven part drives the connecting part to rotate around its own axis, and the linkage switches between a raised state and a lowered state. When the linkage is in the raised state, the raised surface of the linkage part abuts upward against the lower coupler, so that the lower coupler is in the extended position. When the linkage is in the lowered state, the recessed surface of the linkage part abuts upward against the lower coupler, so that the lower coupler is in the retracted position.

[0283] In one embodiment, when the actuator 272 rotates, the actuator 272 and the driven part 2712 are shaped to fit together, so that the linkage 271 rotates around the rotational connection between the connecting part 2711 and the support base 21. In this solution, the fit structure between the actuator 272 and the driven part 2712 is simple and easy to process.

[0284] Furthermore, when the actuator 272 rotates, the actuator 272 and the driven part 2712 cooperate through the cooperation of the protrusion and the groove, so that the linkage 271 rotates around the rotational connection between the connecting part 2711 and the support base 21. In this solution, the cooperation structure between the actuator 272 and the driven part 2712 is simple and easy to process.

[0285] Furthermore, such as Figure 29 and Figure 32 As shown, the driven part 2712 is a downwardly extending driven protrusion. The actuator 272 is provided with an active groove 2721 and a lifting part 2722. The lifting part 2722 is higher than the active groove 2721. During the rotation of the actuator 272, the relative positions of the active groove 2721 and the lifting part 2722 with respect to the driven part 2712 will change. Specifically, when the driven part 2712 and the active groove 2721 are opposite each other in the vertical direction, that is, when the actuator 272 rotates to the point where the active groove 2721 is below the driven part 2712, the driven part 2712 extends into the active groove 2721, so that the linkage 271 is in a fallen state; when the lifting part 2722 lifts the driven part 2712 upward, that is, when the actuator 272 rotates to the point where the lifting part 2722 is below the driven part 2712, so that the linkage 271 is in a lifted state.

[0286] Furthermore, such as Figure 32As shown, the active groove 2721 extends along the rotation direction of the actuator 272. The two ends of the active groove 2721 extend upwards at an angle, forming a first inclined surface 27211 and a second inclined surface 27212, respectively. The first inclined surface 27211 and the second inclined surface 27212 are spaced apart along the rotation direction of the actuator 272. Figure 29 , Figure 30 , Figure 33 and Figure 34 As shown, when the linkage 271 switches from the raised state to the lowered state, the driven part 2712 moves along the first inclined surface 27211. This allows the driven part 2712 to smoothly and quickly extend into the active groove 2721, thereby causing the linkage 271 to quickly switch from the raised state to the lowered state. When the linkage 271 switches from the lowered state to the raised state, the driven part 2712 moves along the second inclined surface 27212. This allows the driven part 2712 to smoothly and quickly move until its bottom wall abuts against the raised part 2722, thereby causing the linkage 271 to quickly switch from the lowered state to the raised state. Preferably, the driven part 2712 has a structure that is larger at the top and smaller at the bottom, providing structural strength while reducing the friction between the driven part 2712 and the active groove 2721.

[0287] Furthermore, such as Figure 29 and Figure 32 As shown, there are two active grooves 2721, two lifting portions 2722, and two driven portions 2712. The active grooves 2721 and the lifting portions 2722 are alternately distributed along the rotation direction of the actuator 272; the two driven portions 2712 are symmetrically arranged about the central axis of the actuator 272. In this way, every time the actuator 272 rotates 90°, the linkage 271 can switch between the raised position and the lowered position.

[0288] Of course, the specific scheme of the cooperation between the actuator 272 and the driven part 2712 through the protrusion and the groove is not limited to this. The driven part 2712 can also be configured as a driven groove (not shown in the figure) and a protruding surface (not shown in the figure), and a lifting protrusion (not shown in the figure) can be provided on the actuator 272. The structure and positional relationship between the driven groove and the protruding surface are the same as the structure and positional relationship between the active groove 2721 and the lifting part 2722 in the aforementioned embodiment. The driven groove and the active groove 2721 have opposite groove opening directions, and the lifting protrusion has the same structure as the driven part 2712 in the aforementioned embodiment but extends in the opposite direction. When the actuator 272 rotates to the point where the lifting protrusion is below the driven groove, the lifting protrusion extends into the driven groove, thereby causing the linkage 271 to be in a lowered state; when the actuator 272 rotates to the point where the lifting protrusion is below the protruding surface of the driven part 2712, the lifting protrusion pushes the protruding surface of the driven part 2712 upward, thereby causing the linkage 271 to be in a lifted state.

[0289] In one implementation, such as Figure 25 and Figure 26 As shown, the base assembly 2 also includes a switch 28, which is used to control the start and stop of the motor so that the user can adjust the position of the lower coupler 221.

[0290] Furthermore, switch 28 also includes a button 281 and a micro switch 282. Button 281 and micro switch 282 are linked, and button 281 is movably mounted on the cover 2162 of support base 21. When the motor is not turned on, pressing button 281 with external force turns on micro switch 282, thereby controlling the motor to turn on. When the motor is turned on, pressing button 281 with external force turns off micro switch 282 and controls the motor to stop running. Of course, the linkage between button 281 and micro switch 282 is not limited to this. It can also be that pressing and holding button 281 turns on micro switch 282, and releasing button 281 turns off micro switch 282.

[0291] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this utility model that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this utility model and do not limit the scope of protection of this utility model patent.
