Description

Technical Field

[0001] This utility model relates to the field of snow melting machine technology, specifically to the agitator structure of a snow melting machine and the snow melting machine itself. Background Technology

[0002] A slush machine, also known as a slush maker, is a machine that adds fruit juice and sugar to make slushies in a specific ratio. Widely used in beverage shops, it can turn various fruit juices into refreshing, slushy drinks. A slush machine mainly consists of a refrigeration system, a stirring system, and a raw material tank. The refrigeration system cools the materials in the tank, while the stirring system mixes and stirs the materials. When discharge is needed, the material is released through a valve and handle on the raw material tank. Specifically, when the slush machine is making slushies, the motor drives the stirrer through a drive shaft. The stirrer, located inside the raw material tank and positioned outside the evaporator, agitates the material. Under the combined action of the evaporator and stirrer, the slurry in the raw material tank is cooled and stirred into a slushy state. The sealing of the stirrer within the raw material tank often affects the quality of the slushies.

[0003] When the existing snow melting machine agitator rotates inside the raw material cylinder, the slurry is often easily contaminated due to poor sealing of the drive shaft, which in turn affects the quality of the snow melting and limits the applicability of the snow melting machine. This solution addresses this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a stirrer structure and a snow melting machine. By having the first conical surface of the sealing ring contact the conical groove of the connecting sleeve, and the second conical surface tightly adhere to the side of the evaporator, the deformation of the first and second conical surfaces increases the contact area of ​​the sealing ring, preventing the oil on the drive shaft from contaminating the raw materials in the raw material cylinder, resulting in higher snow melting quality and thus improving the applicability of the snow melting machine.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: the agitator structure of the snow melting machine includes a stirring assembly, a drive shaft with one end separably connected to the stirring assembly, a reducer with the drive end connected to the other end of the drive shaft, and a motor connected to the reducer. A sealing ring is provided between the drive shaft and the stirring assembly. The stirring assembly includes stirring blades and a connecting sleeve with the side of the stirring blades. One side of the sealing ring abuts against the inner side of one end of the connecting sleeve, and the other side of the sealing ring abuts against one side of the evaporator in the snow melting machine.

[0006] The inner side of the connecting sleeve is provided with a conical groove. The sealing ring includes a first conical surface that can be separably embedded in the conical groove, a second conical surface that abuts against one side of the evaporator, and a baffle disposed between the first conical surface and the second conical surface. The baffle is separably abutted against the connecting sleeve.

[0007] The side of the drive shaft is provided with an annular groove, and a retaining spring is detachably embedded in the annular groove, the retaining spring abutting against the other side of the evaporator.

[0008] The bottom of the connecting sleeve is provided with a semi-circular keyway, and one end of the drive shaft is provided with a semi-circular key, which is detachably embedded in the semi-circular keyway.

[0009] The other end of the drive shaft is provided with a semi-circular key two, and a bushing is sleeved on the outside of the semi-circular key two. The drive end of the reducer is provided with a semi-circular key three, which is detachably inserted into the bushing and connected to the semi-circular key two.

[0010] The side of the drive shaft is provided with an annular groove, and a retaining spring is embedded in the annular groove to prevent the bushing from moving.

[0011] A sealing block is fitted at the end of the connecting sleeve, and the sealing block contacts the inside of the raw material cylinder of the snow melting machine.

[0012] The stirring blades are spiral blades.

[0013] The motor is a shaded-pole motor.

[0014] On the other hand, this application also provides a snow melting machine, which includes the aforementioned agitator structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The first conical surface of the sealing ring contacts the conical groove of the connecting sleeve, and the second conical surface is in close contact with the side of the evaporator. The deformation of the first and second conical surfaces increases the contact area of ​​the sealing ring, avoids the contamination of the raw material in the raw material cylinder by the oil on the drive shaft, and the quality of snow melting is higher, thereby improving the applicability of the snow melting machine.

[0017] (2) A reducer connected to the shaded pole motor is provided to drive the transmission shaft, and the transmission shaft drives the stirring assembly to stir the raw materials in the raw material cylinder. On the one hand, the setting of the reducer increases the rotational torque of the stirring assembly and reduces the load of the motor, making the snow melting machine more durable. On the other hand, the setting of the transmission shaft increases the distance between the reducer and the stirring assembly, further avoiding the contamination of the raw materials in the raw material cylinder by the reducer, and making the stirrer more applicable.

[0018] (3) A semi-circular key 1 that can be detachably connected to the semi-circular keyway inside the connecting sleeve is provided at one end of the drive shaft, and a semi-circular key 2 that is connected to the reducer is provided at the other end of the drive shaft. A bushing is fitted on the outside of the semi-circular key 2, which makes the connection between the stirring assembly and the drive shaft and the connection between the drive shaft and the reducer safer and more reliable, and the disassembly is convenient and quick, further improving the applicability of the snow melting machine.

[0025] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0026] See Figures 1-5 The agitator structure of the snow melting machine includes an agitator assembly 1, a drive shaft 2 that is detachably connected to the agitator assembly 1, a reducer 3 whose drive end is connected to the other end of the drive shaft 2, and a motor 4 connected to the reducer 3. A sealing ring 5 is provided between the drive shaft 2 and the agitator assembly 1. The agitator assembly 1 includes a stirring blade 11 and a connecting sleeve 12 whose side is connected to the stirring blade 11. One side of the sealing ring 5 abuts against the inner side of one end of the connecting sleeve 12, and the other side of the sealing ring 5 abuts against one side of the evaporator 6 in the snow melting machine. Specifically, the sealing ring 5 is made of silicone, and the transmission ratio of the reducer 3 is 70:1.

[0027] It is understood that the inner side of the connecting sleeve 12 is provided with a conical groove 121, and the sealing ring 5 includes a conical surface 51 that can be separably embedded in the conical groove 121, a conical surface 52 that abuts against one side of the evaporator 6, and a baffle 53 disposed between the conical surface 51 and the conical surface 52. The baffle 53 abuts against the connecting sleeve 12 in a separable manner.

[0028] Furthermore, an annular groove is provided on the side of the drive shaft 2, and a snap ring 21 is detachably embedded in the annular groove 2, which abuts against the other side of the evaporator 6.

[0029] Furthermore, the bottom of the connecting sleeve 12 is provided with a semi-circular keyway 122, and one end of the drive shaft 2 is provided with a semi-circular key 23, which is detachably embedded in the semi-circular keyway 122.

[0030] The other end of the drive shaft 2 is provided with a semi-circular key 24, and a bushing 25 is sleeved on the outside of the semi-circular key 24. The drive end of the reducer 3 is provided with a semi-circular key 31, which is separably inserted into the bushing 25 and connected to the semi-circular key 24.

[0031] Specifically, the side of the drive shaft 2 is provided with an annular groove 2, and a retaining ring 22 is embedded in the annular groove 2 to prevent the bushing 25 from moving.

[0032] A sealing block 7 is fitted at the end of the connecting sleeve 12, and the sealing block 7 contacts the inside of the raw material cylinder of the snow melting machine.

[0033] The stirring blade 11 is a spiral blade, so that the stirring blade 11 can have a better stirring effect.

[0034] Motor 4 is a shaded-pole motor. By using a shaded-pole motor, the noise of the snow melting machine is reduced and the transmission efficiency is increased.

[0035] On the other hand, this application also provides a snow melting machine, which includes a stirrer structure.

[0036] The specific working process and principle of this utility model:

[0037] The installation process of the stirrer structure is as follows: Snap ring 1 21 and snap ring 22 are installed on the drive shaft 2. One end of the drive shaft 2 is passed through the evaporator 6, and one end of the evaporator 6 abuts against snap ring 1 21. The bushing 25 is fitted onto the outside of the semi-circular key 24. Snap ring 22 is used to prevent the bushing 25 from moving. Then, the drive shaft 2 with the evaporator 6 is fitted onto the outside of the semi-circular key 31 at the output end of the reducer 3, so that the semi-circular key 31 and the semi-circular key 24 are connected. The other end of the evaporator 6 is then firmly connected to the snow melting machine housing, completing the installation of the evaporator 6 and the drive shaft 2.

[0038] The sealing ring 5 is fitted onto the drive shaft 2, and the sealing ring 5 is pressed tightly against the side of the evaporator 6. Then, the stirring blade 11 of the stirring assembly 1 is fitted onto the outside of the evaporator 6, and the connecting sleeve 12 is fitted onto the end of the drive shaft 2, so that the conical surface 51 of the sealing ring 5 is embedded in the conical groove 121 of the connecting sleeve 12, and the semi-circular key 23 of the drive shaft 2 is embedded in the semi-circular keyway 122. At this time, the conical surface 52 of the sealing ring 5 is also tightly fitted to the side of the evaporator 6, and the installation of the stirring assembly 1 is completed.

[0039] Install the sealing block 7 at the end of the connecting sleeve 12 in the mixing assembly 1, then place the raw material cylinder of the snow melting machine on the outside of the mixing assembly 1 so that the sealing block 7 is in close contact with the raw material cylinder. Finally, install the valve stem and handle on the raw material cylinder to complete the installation of the snow melting machine.

[0040] After the raw material is fed into the cylinder, the motor 4 is started. The motor 4 drives the reducer 3 to move. The output end of the reducer 3 drives the transmission shaft 2 to rotate. The transmission shaft 2 drives the entire stirring assembly 1 to rotate inside the raw material cylinder.

[0041] The sealing ring 5 has a conical surface 51 that contacts the conical groove 121 of the connecting sleeve 12, and the conical surface 52 is in close contact with the side of the evaporator 6. The deformation of the conical surface 51 and the conical surface 52 increases the contact area of ​​the sealing ring 5, which avoids the oil on the drive shaft 2 from contaminating the raw materials in the raw material cylinder, resulting in higher quality snow melting and thus improving the applicability of the snow melting machine.

[0042] A reducer 3 connected to the shaded-pole motor drives the transmission shaft 2, which in turn drives the stirring assembly 1 to stir the raw materials in the raw material cylinder. On the one hand, the reducer 3 increases the rotational torque of the stirring assembly 1 and reduces the load on the motor 4, making the snow melting machine more durable. On the other hand, the transmission shaft 2 increases the distance between the reducer 3 and the stirring assembly 1, further preventing the reducer 3 from contaminating the raw materials in the raw material cylinder, and making the stirrer more versatile.

[0043] One end of the drive shaft 2 is provided with a semi-circular key 23 that can be detachably connected to the semi-circular keyway 122 inside the connecting sleeve 12, and the other end of the drive shaft 2 is provided with a semi-circular key 24 that connects to the reducer 3. A bushing 25 is fitted on the outer side of the semi-circular key 24, making the connection between the stirring assembly 1 and the drive shaft 2, as well as the connection between the drive shaft 2 and the reducer 3, safer and more reliable. Disassembly is convenient and quick, further improving the applicability of the snow melting machine.

[0044] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
