Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1-4 The utility model provides the following technical solutions: a water channel conversion mechanism for a coffee machine, comprising a valve core assembly 1, a cold water pipe 2 is arranged on one side of the valve core assembly 1, a hot water pipe 8 is arranged on the side of the valve core assembly 1 away from the cold water pipe 2, an outlet pipe 4 is installed above the valve core assembly 1, a water supply pipe 6 is installed above the water outlet pipe 4, a drain pipe 5 is arranged above the water supply pipe 6, the valve core assembly 1 is connected to the cold water pipe 2 and the hot water pipe 8 through two rotating adjustment devices 3, and the water supply pipe 6 and the drain pipe 5 are connected through a purification treatment device 7.

[0023] Specifically, the rotary adjustment device 3 includes a fixed block 31, a rotary tube 32, a connecting tube 36 and a rotating plate 37. The fixed blocks 31 are installed on the outer sides of the lower ends of the cold water pipe 2 and the hot water pipe 8. The rotary tube 32 is installed on the central position of the fixed block 31 through a bearing. The valve core assembly 1 is connected to the two rotary tubes 32 through two connecting tubes 36. The rotating plate 37 is installed on the outer sides of the connecting tubes 36.

[0024] By adopting the above technical solution, the staff can adjust the angle of the water outlet pipe 4 to a certain extent through the cooperation of the rotating pipe 32 and the connecting pipe 36 when necessary, so as to better meet the working needs in different situations.

[0025] Specifically, the rotation adjustment device 3 also includes a first knob 33, a first screw 34 and a rubber extrusion block 35. The first screw 34 is threadedly installed on the bottom of the fixed block 31, the rubber extrusion block 35 is installed on the side of the first screw 34 close to the rotating plate 37 through a bearing, and the first knob 33 is installed on the side of the first screw 34 away from the rotating plate 37.

[0026] By adopting the above technical solution, the staff can prevent the rotating plate 37 and the water outlet pipe 4 and other structures from rotating by squeezing the rubber squeezing block 35 when necessary, thereby reducing the possibility of accidental rotation of the water outlet pipe 4 and other structures.

[0027] When the present embodiment is used, when the coffee machine needs to use the mechanism to perform water channel conversion, the cold water pipe 2 and the hot water pipe 8 are connected to the cold water channel and the hot water channel respectively, and the water pipe of the coffee machine is connected to the drain pipe 5, and then the two first knobs 33 in the rotary adjustment device 3 are respectively turned to drive the two first screws 34 to rotate, the first screws 34 are threadedly connected to the fixing block 31, the first screws 34 are bearing-connected to the rubber extrusion block 35, and the outer side of the rubber extrusion block 35 is closely attached to the bottom inner side of the fixing block 31, so the two first screws 34 The two rubber extrusion blocks 35 are driven to move, thereby releasing the extrusion limit of the rotating plate 37 and other structures. Then the staff pulls the valve core assembly 1 to make the water outlet pipe 4 rotate to the required angle, and then rotates the two first knobs 33 in the opposite direction respectively, thereby driving the two rubber extrusion blocks 35 to re-extrude the rotating plate 37 and other structures. Then the valve core assembly 1 is manipulated, and the cold water or hot water required by the staff passes through the water outlet pipe 4, the water supply pipe 6 and the drain pipe 5 and is discharged into the coffee machine, thereby performing water path conversion. The rotating tube 32 and the connecting tube 36 play a role in water supply.

[0028] Example 2

[0029] The difference between this embodiment and embodiment 1 is that the purification device 7 includes a connecting box 71, a movable box 72, a second knob 73, a second screw 74, activated carbon 75 and a partition 76. The water supply pipe 6 and the drainage pipe 5 are connected via the connecting box 71. A second screw 74 is threadedly installed on one side of the connecting box 71 near the edge. The movable box 72 is installed on the second screw 74 at a position inside the connecting box 71 through a bearing. The top and bottom of the movable box 72 are both installed with a partition 76. The inside of the movable box 72 is filled with activated carbon 75. The second knob 73 is installed on the side of the second screw 74 away from the connecting box 71.

[0030] By adopting the above technical solution, the mechanism can purify the discharged water to a certain extent through the cooperation of structures such as activated carbon 75 and connecting box 71 when necessary, so as to better meet the working needs in different situations.

[0031] Specifically, the width and height of the inner side of the connection box 71 are equal to the width and height of the outer side of the moving box 72 .

[0032] By adopting the above technical solution, it is ensured that the inner side of the connection box 71 and the outer side of the moving box 72 can be closely attached to each other, thereby preventing a gap between the connection box 71 and the moving box 72, thereby preventing water leakage.

[0033] Specifically, the purification device 7 further includes a threaded block 77 , and the threaded block 77 is threadedly mounted on a side of the moving box 72 away from the second screw rod 74 .

[0034] By adopting the above technical solution, the staff can unscrew the threaded block 77 to replace the activated carbon 75 when necessary, thereby reducing the difficulty of replacing the activated carbon 75 and further alleviating the labor burden of the staff.

[0035] When this embodiment is used, during use, water will pass through the connecting box 71 in the purification treatment device 7 and the two partition nets 76 on the mobile box 72 and enter the drain pipe 5. During this process, the activated carbon 75 will purify the water to a certain extent, so as to better meet the needs of the staff. If there is no need to purify the water, the staff can turn the second knob 73 to drive the second screw 74 to rotate. The second screw 74 is threadedly connected to the connecting box 71, and the second screw 74 is bearing-connected to the mobile box 72. The outer side of the mobile box 72 and the inner side of the connecting box 71 are tightly attached to each other, so the second screw 74 drives the mobile box 72 and other structures to move until the mobile box 72 leaves the position between the water supply pipe 6 and the drain pipe 5, thereby preventing the purification work from being carried out. When necessary, the staff can unscrew the threaded block 77 to replace the activated carbon 75.

[0036] In the utility model, the valve core assembly 1 composed of a switching valve body, an adjusting handle, a connecting cylinder, an adjusting plate, a mounting hole and a slide groove, and the structure and principle of the water outlet pipe 4 have been disclosed in a hot and cold water switching valve disclosed in Chinese patent application No. 202021309438.5. Its working principle is to take a toilet as an example. The above-mentioned water-using equipment is a toilet. The water outlet pipe connected to the water tank of the toilet, the hot water pipe is connected to the hot water pipe of the household main water pipe, and the cold water pipe is connected to the cold water pipe of the household main water pipe. When the switching valve body is adjusted to connect the cold water pipe with the water tank of the toilet, the cold water in the household main water pipe (cold water pipe) enters the toilet water tank, thereby achieving the purpose of replenishing water in the toilet water tank. When hot water is not needed, the regulator switches the valve body to connect the hot water pipe to the toilet tank. The cold water in the household main water pipe (hot water pipe) (the front end of the hot water pipe is cold water and cannot be used) enters the toilet tank, thereby replenishing the toilet tank and avoiding the waste of water. After the water in the household main water pipe (hot water pipe) becomes hot, the regulator switches the valve body to disconnect the hot water pipe from the toilet tank.

[0037] The working principle and use process of the utility model are as follows: when the coffee machine needs to use the mechanism to perform water circuit conversion work, the cold water pipe 2 and the hot water pipe 8 are connected to the cold water circuit and the hot water circuit respectively, and the water pipe of the coffee machine is connected to the drain pipe 5, and then the two first knobs 33 in the rotary adjustment device 3 are respectively turned, thereby driving the two first screws 34 to rotate, the first screws 34 are threadedly connected to the fixed block 31, the first screws 34 are bearing-connected to the rubber extrusion block 35, and the outer side of the rubber extrusion block 35 is tightly attached to the bottom inner side of the fixed block 31, so the two first screws 34 drive the two rubber extrusion blocks 35 to move, thereby releasing the extrusion limit of the rotating plate 37 and other structures, and then the staff pulls the valve core assembly 1 to make the water outlet pipe 4 rotate to the required angle, and then the two first knobs 33 are respectively rotated in the opposite direction, thereby driving the two rubber extrusion blocks 35 to re-extrude and limit the rotating plate 37 and other structures, and then the valve core assembly 1 is operated, and the staff needs cold water or hot water. The water is discharged into the coffee machine through the water outlet pipe 4, the water supply pipe 6 and the drain pipe 5, thereby converting the water path. The rotating pipe 32 and the connecting pipe 36 play the role of conveying water. During use, the water will pass through the connecting box 71 in the purification treatment device 7 and the two partitions 76 on the movable box 72 and enter the drain pipe 5. During this process, the activated carbon 75 will purify the water to a certain extent, thereby better meeting the needs of the staff. If there is no need to purify the water, the staff can turn the second knob 73 to drive the second screw 74 to rotate. The second screw 74 is threadedly connected to the connecting box 71, and the second screw 74 is bearing-connected to the movable box 72. The outer side of the movable box 72 is tightly attached to the inner side of the connecting box 71, so the second screw 74 drives the movable box 72 and other structures to move until the movable box 72 leaves the position between the water supply pipe 6 and the drain pipe 5, thereby preventing the purification work from being carried out. When necessary, the staff can unscrew the threaded block 77 to replace the activated carbon 75.
