[0033] As Figure 1 , Figure 2 and Figure 3 illustrated, the embodiment of the utility model provides a water dispenser, include: body 1, water outlet pipe 2, sleeve 3, sliding block 4, water pipe 5 and reel 6.

[0034] Specifically, the cavity 11 for placing the water bucket 7 is arranged in the body 1.

[0035] Water outlet pipe 2 is arranged on body 1.

[0036] Sleeve 3 is arranged in cavity 11, sleeve 3 can move in the vertical direction between the first position (the position of sleeve 3 as shown in Figure 1 Second position (the position of sleeve 3 as shown in Figure 2 ), the first position is higher than the second position. When sleeve 3 moves to the second position, the lower end of the sleeve can be sleeved outside the bucket mouth 71 of the water bucket 7 to hold and limit the bucket mouth 71. When sleeve 3 moves to the first position, sleeve 3 is separated from the bucket mouth 71.

[0037] Sliding block 4 is arranged in sleeve 3, sliding block 4 can slide in the vertical direction in sleeve 3, and a through hole penetrating sliding block 4 in the vertical direction is arranged on sliding block 4.

[0038] Referring to Figure 3 , water pipe 5 includes first pipe body 51 and second pipe body 52, first pipe body 51 is a hose, the hardness of second pipe body 52 is greater than that of first pipe body 51, the end of first pipe body 51 is communicated with water outlet pipe 2, second pipe body 52 penetrates through the through hole, and limiting protrusion 521 is arranged on the outer wall of second pipe body 52, and limiting protrusion 521 is located below sliding block 4. Specifically, the outer diameter of second pipe body 52 is less than the diameter of the sealing cover of the water bucket 7.

[0039] The reel 6 can rotate around its own axis, and the first pipe body 51 is at least partially wound on the reel 6.

[0040] In some embodiments, sleeve 3 is connected with first driving mechanism (not shown in the figure), and the first driving mechanism is used for driving sleeve 3 to move in the vertical direction between the first position and the second position. The utility model discloses a water dispenser by setting sleeve 3 and first driving mechanism, when first driving mechanism drives sleeve 3 to move to the second position, it can guarantee that second pipe body 52 is coaxial with the bucket mouth 71 of water bucket 7, so that second pipe body 52 smoothly punctures the bucket mouth 71 of water bucket 7 in subsequent operation process. Exemplarily, the first driving mechanism can be a motor.

[0041] Optionally, the water dispenser further comprises a second driving mechanism (not shown in the figure) connected with the sliding block 4, the second driving mechanism is used to drive the sliding block 4 to move downward along the vertical direction after the sleeve 3 moves to the second position, and the second driving mechanism provides a downward force to the sliding block 4 and the second pipe body 52 to push the lower end of the second pipe body 52 to insert into the bucket mouth 71 of the water bucket 7. Exemplarily, the second driving mechanism can be a motor.

[0042] Optionally, as shown in Figure 1 and Figure 2 , the water dispenser further comprises a third driving mechanism (not shown in the figure), the output end of the third driving mechanism is connected with the reel 6, and the third driving mechanism is used to drive the reel 6 to rotate in the R1 direction as shown in Figure 1 and Figure 2 or in the R2 direction as shown in Figure 1 and Figure 2 , so as to release or wind the water pipe 5. Exemplarily, the third driving mechanism can be a motor.

[0043] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the upper part of the sleeve 3 is provided with two recessed wheels 8, and the water pipe 5 passes through the gap between the two recessed wheels 8. Since the water pipe 5 passes through the gap between the two recessed wheels 8, the two recessed wheels 8 can clamp the water pipe 5, and when the reel 6 releases the water pipe 5, the two recessed wheels 8 guide the water pipe 5 moving downward.

[0044] Further, the water dispenser further comprises a fourth driving mechanism for driving the rotation of the recessed wheels 8, and the rotation directions of the two recessed wheels 8 are opposite. The water dispenser of the present application is provided with the fourth driving mechanism, which can drive the recessed wheels 8 to move the water pipe 5 upward and downward, so as to assist the winding and releasing of the water pipe 5. Exemplarily, the fourth driving mechanism can be a motor.

[0045] Specifically, when water is needed, the water bucket is placed below the sleeve 3, at this time, the first driving mechanism is started to drive the sleeve 3 to move downward, and the sliding block 4 moves downward together with the sleeve 3. Since the second pipe body 52 of the water pipe 5 is inserted into the through hole on the sliding block 4, the limiting protrusion 521 provided on the second pipe body 52 is located below the sliding block 4, and the water pipe 5 is at least partially wound on the reel 6, so that the sliding block 4 exerts a downward pushing force on the limiting protrusion 521 when moving downward, so as to drive the second pipe body 52 to move downward together. The second pipe body 52 pulls the reel 6 to move along the R1 direction as shown in Figure 1R2 direction to release the water pipe 5. When the sleeve 3 moves to the second position, the sleeve 3 is sleeved outside the bucket mouth 71 to hold and limit the bucket mouth 71. At this time, the first driving mechanism stops running, and the second driving mechanism drives the sliding block 4 to move downward. The sliding block 4 exerts a downward thrust on the limiting protrusion 521 in the process of moving downward to drive the second pipe body 52 to move downward along the inner wall of the sleeve 3. Since the sleeve 3 can ensure that the second pipe body 52 is coaxial with the bucket mouth 71 of the water bucket 7, and the second pipe body 52 has a greater hardness, the lower end of the second pipe body 52 can directly pierce the sealing cover of the water bucket 7 in the process of descending. When the sealing cover of the water bucket 7 is pierced, the second driving mechanism stops running. Subsequently, the third driving mechanism and the fourth driving mechanism are started, and the third driving mechanism drives the reel 6 to rotate along the R1 direction to release the first pipe body 51 wound on the reel 6. At the same time, the fourth driving mechanism drives the two recessed wheels 8 to rotate to drive and guide the water pipe 5, and drives the water pipe 5 to extend downward all the time, so that the water inlet end of the water pipe 5 moves to the bottom of the water bucket 7. Subsequently, the third driving mechanism and the fourth driving mechanism stop running. Figure 2

[0046] When the water in the water bucket is used up, the third driving mechanism is first started, the third driving mechanism drives the reel 6 to rotate along the R2 direction to move the first pipe body 51 upward and wind the first pipe body 51 on the reel 6, and the second pipe body 52 moves upward together with the first pipe body 51. When the limiting protrusion 521 on the outer wall of the second pipe body 52 contacts the lower end surface of the sliding block 4, the third driving mechanism continues to work, the fourth driving mechanism is started, and the third driving mechanism and the fourth driving mechanism respectively drive the reel and the two recessed wheels 8 to continue driving the water pipe 5 to move upward. Since the limiting protrusion 521 of the second pipe body 52 exerts an upward force on the sliding block 4, the sliding block 4 moves upward along the inner wall of the sleeve 3 to the upper end of the sleeve 3, and then the third driving mechanism and the fourth driving mechanism stop running. Subsequently, the first driving mechanism is started, the sleeve 3 is driven by the first driving mechanism to move upward to the first position, and the empty water bucket can be taken out to replace a new water bucket.

[0047] In this way, by arranging the sleeve 3, the sliding block 4, the water pipe 5, the reel 6 and the corresponding driving mechanisms of the mechanical components on the water dispenser, the sleeve 3, the sliding block 4 and the reel 6 can be driven according to the requirements of the operator to drive the water pipe 5 to complete the action of piercing the sealing cover of the water bucket 7, and to complete the automatic winding or releasing of the water pipe 5, so as to realize the automatic plugging and unplugging of the water pipe 5, so that the sealing cover does not need to be pierced by hand or other tools during replacement, and the hand does not need to contact the water pipe, thereby avoiding the contact between the hand and the bucket mouth or the water pipe of the water bucket, which causes the water pipe to be contaminated by the bacteria on the hand.

[0048] ​Exemplarily, the circumferential surface of the concave wheel 8 is provided with anti-skid lines.

[0049] Further, referring to Figure 1 and Figure 2 , the bottom of the cavity 11 is provided with a positioning plate 12, the upper surface of the positioning plate 12 is provided with a positioning groove 13, the shape of the positioning groove 13 is matched with the shape of the bottom of the water bucket 7, the positioning groove 13 is used for accommodating the bottom of the water bucket 7 to limit the horizontal movement of the water bucket 7. After the water bucket 7 is placed in the positioning groove 13, the center of the bucket mouth 71 of the water bucket 7 and the center of the second pipe body 52 are located on the same vertical line. The water dispenser of the utility model can align the second pipe body 52 with the bucket mouth 71 after the water bucket 7 is placed in the positioning groove 13, so as to ensure that the second pipe body 52 smoothly enters the bucket mouth 71 by setting the positioning plate 12 at the bottom of the cavity 11 and setting the positioning groove 13 on the upper surface of the positioning plate 12.

[0050] In some embodiments, the sidewall of the machine body is provided with an opening (not shown in the figure), and the positioning plate 12 can slide relative to the machine body 1 in the horizontal direction, so that the positioning plate 12 can at least partially extend out of the opening. When a new water bucket needs to be replaced, the operator can pull out the positioning plate 12 from the cavity 11 through the opening, so as to facilitate the operator to replace the water bucket 7 and save manpower.
