[0002] "Masticating ice machines" are also commonly called "ice cream machines" or "smoothie machines." Masticating ice machines can chew ordinary ice cubes into fine crushed ice for making smoothies, iced drinks and cold drinks. In order to make "smoothies," a chewing ice machine usually requires a driven rotating blade, generally called an ice knife or an ice-making knife, which rotates to cut ice cubes and turn them into crushed ice. With the increasing maturity of chewing ice machine technology and the optimization of the size and performance of chewing ice machines, chewing ice machines are becoming more and more popular and are widely used in beverage stores and homes.

[0003] In the prior art, in chewing ice makers, the ice blade drive device is large in size, produces loud operating noise, and is mostly installed under the ice box. During the ice-making and cooling process of the ice box, a large amount of water droplets will condense on the outside of the ice box.

[0004] To solve the above problems, the main means used in the prior art is to artificially cover the outside of the ice blade drive device with a waterproof layer, but it is found that the waterproof and waterproof effects are unsatisfactory, and it will also cause the heat dissipation of the ice blade drive device to be limited, or to strengthen the sealing performance of the ice blade drive device itself and improve the waterproof ability of the waterproof ice blade drive device itself.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0044] See also Figure 1 and Figure 2 The utility model discloses an ice blade driving device 10 for an ice making machine.

[0045] The ice blade drive device 10 is placed above the ice box 102 of the ice maker and can be detachably installed. The ice blade drive device 10 can be detachably installed at a suitable position on the ice maker body 101 of the ice maker, or can be detachably installed on the ice box 102, and it must be ensured that the ice blade drive device 10 is located above the ice box 102 in the ice maker.

[0046] The ice blade driving device 10 includes a driving housing 1 and a power input mechanism 2, a power output mechanism 3 and a transmission mechanism 4 installed in the driving housing 1, and the transmission mechanism 4 connects the power input mechanism 2 and the power output mechanism 3. The power output mechanism 3 includes a power output shaft 31, and the power output shaft is connected to the ice blade that can be inserted into the ice making box.

[0047] In the above scheme, the power input mechanism 2 transmits power, which is then transmitted to the power output mechanism 3 through the transmission mechanism 4, and then transmitted to the ice skates connected thereto through the power output mechanism 3, thereby driving the ice skates to move.

[0048] In the above scheme, the ice blade drive device 10 can be detachably installed, so as to realize the modularization of the ice blade drive device, facilitate installation, maintenance and replacement, and also increase its applicability and compatibility, that is, it can be adapted to cooperate with different types of drive devices for different types of ice making machines. The ice blade drive device can be detachably installed, and the ice blade drive device 10 can be quickly installed and disassembled. When the ice blade drive device 10 needs to be replaced, repaired, maintained, etc., the ice blade drive device 10 can be quickly disassembled and taken out from the ice making machine, and it is no longer necessary to operate in the narrow space at the bottom and side of the ice making box, which reduces the difficulty of loading and unloading operations of the ice blade drive device 10.

[0049] In the above scheme, after the ice blade drive device 10 is installed, it is ensured that the ice blade drive device 10 is located above the ice box 102 in the ice maker, so that when the ice maker makes ice, the water droplets condensed on the outer wall of the ice box will no longer drip onto the ice blade drive device, and the electrical components inside the ice blade drive device 10 will no longer be soaked or contacted with the condensed water dripping from the outside of the ice box 102, which completely solves the problem that the ice blade drive device 10 will short-circuit due to the electrical components being soaked in water. That is, it is ensured that the ice blade drive device 10 is located above the ice box 102 in the ice maker, which reduces the failure rate and damage rate of the ice blade drive device 10 and prolongs the service life of the ice blade drive device.

[0050] At the same time, the ice blade drive device 10 is placed above the ice box of the ice maker, so that when the ice maker makes ice, the water droplets condensed on the outer wall of the ice box 102 will no longer drip onto the ice blade drive device 10, and the requirements for the waterproof and sealing performance of the ice blade drive device 10 itself are reduced, which directly reduces the manufacturing cost of the ice blade drive device 10.

[0051] In one embodiment, the power output shaft 31 is detachably connected to the ice blade 103, so that the ice blade drive device 10 can be quickly installed and disassembled when the ice blade drive device 10 needs to be replaced, repaired, maintained, etc.

[0052] like Figure 1 As shown, on the driving housing 1, the side facing the ice box 102 is a mounting surface 12, and the power output shaft 31 extends from the mounting surface 12 and is connected to the ice blade 103. The mounting surface 12 is a sealing surface and is provided with a plurality of connecting blind holes 13, the axes of the connecting blind holes 13 are parallel to the power output shaft 31, and the ice blade driving device 10 is detachably connected to the ice maker body 101 through the connecting blind holes 13.

[0053] A connecting blind hole 13 is provided on the mounting surface 12. When the power output shaft 31 is connected to the ice blade driving end 107 of the ice blade 103, the connecting blind hole 13 on the mounting surface is also installed at the corresponding position on the ice maker, so that the stable installation of the ice blade driving device 10 is achieved, and the installation stability of the ice blade driving device 10 itself is ensured. The stable installation of the ice blade driving device 10 reduces the vibration amplitude when the ice blade driving device 10 outputs power, so that the working noise and vibration of the ice blade driving device are reduced, and at the same time, it also ensures that the ice blade driving device drives the ice blade more stably, and also ensures the stability of the ice blade when it is working, and reduces the vibration and noise of the ice blade itself when it is working.

[0054] Since the mounting surface is downward and toward the ice box, and after the ice blade drive device is installed, the mounting surface will inevitably contact one side of the ice box, or be relatively close to it, in order to improve the waterproof performance of the ice blade drive device 10, the mounting surface 12 is set as a sealing surface. In order to realize that the mounting surface 12 is a sealing surface, the drive housing 1 can be set, and the part of the housing on the drive housing 1 that includes the mounting surface 12 should be set as an integral structure, so as to avoid the presence of a contact sealing surface near the mounting surface 12 as much as possible, avoid the failure of the seal between the two surfaces that contact and seal with each other, and avoid the problem of reduced waterproof ability of the ice blade drive device 10 due to sealing problems.

[0055] like Figure 1 and Figure 2 As shown, in order to ensure the installation effect of the ice blade drive device 10 and enhance the installation stability of the ice blade drive device 10, at least two connection blind holes 13 are provided on the installation surface 12 of the ice blade drive device 10, and generally two, three or four are preferably selected. Multiple connection blind holes are evenly arranged on the installation surface 12, and multiple connection blind holes are evenly arranged on the installation surface around the power output shaft, so that when the installed ice blade drive device 10 is working, each position on the drive housing 1 is evenly subjected to the reverse force of the ice-making torque, ensuring the stability and service life of the drive housing 1, and ensuring the stability and service life of the ice blade drive device 10.

[0056] like Figure 1 The connecting blind hole 13 is not connected to the internal space of the driving shell 1. On the premise of ensuring that the connecting blind hole 13 realizes the connection function, water vapor leakage problem is avoided at the connecting blind hole position, and water droplets or water vapor carried on the installation surface close to or in contact with the ice box 102 after installation are avoided from entering the interior of the driving shell 1 through the connecting blind hole, and the possibility of water droplets and water vapor entering the interior of the ice blade driving device 10 is eliminated as much as possible.

[0057] like Figure 1 and Figure 2As shown, the power output shaft 31 is provided with a connection hole 32 which is coaxial with the power output shaft 31 and connected to the ice blade 103. During installation, the power output shaft 31 is directly sleeved on the ice blade 103 through the connection hole 32, so as to realize the detachable connection and installation between the power output shaft 31 and the ice blade, and the connection operation is simple, fast, and reliable.

[0058] By connecting with the ice blade 103 through the connecting hole 32, it can also be ensured that the rotation axis of the ice blade 103 is coaxial with the power output shaft 31, so that it is convenient to control the working direction and trajectory of the ice blade.

[0059] In order to further ensure the reliable connection between the power output shaft 31 and the ice blade 103, the connecting hole 32 is set as a cylindrical hole of non-equal diameter, ensuring that the connecting hole 32 has a certain limiting effect when connected to the ice blade 103, ensuring that the power output shaft 31 can smoothly transmit the motion to the ice blade and drive the ice blade to work, avoiding relative motion problems such as slipping between the connecting hole and the ice blade when power is transmitted.

[0060] The cylindrical holes with non-uniform diameters can generally be rectangular cylindrical holes or semicircular holes or multiple semicircular combination holes, or limit grooves can be set on the inner wall of the circular cylindrical hole. Figure 1 The middle connecting hole 32 is a hexagonal hole.

[0061] In this solution, the power input mechanism 2 includes a drive motor, a motor shaft of the drive motor is in transmission connection with the transmission mechanism 4, and the drive motor transmits the rotational motion output by the drive motor to the transmission mechanism 4 via the motor shaft.

[0062] Because the driving motor is the core component of the ice blade driving device 10, and is also a component that is very prone to failure or short circuit due to contact with water vapor, in this embodiment, a motor cover 21 that can be detachably mounted on the driving housing 1 is provided on the outside of the driving motor, and the motor cover 21 is placed outside the driving housing 1 and away from the ice box 102. The motor cover 21 is sealed and connected to the driving housing 1 to protect the motor and prevent the driving motor from being corroded by water vapor inside the ice maker or outside the ice box. The motor cover 21 is separated from the driving housing 1, so that the motor cover 21 can be processed separately. Generally, metal is selected as the raw material for the production of the motor cover, and plastic is selected as the raw material for the driving housing 1, which is convenient to process and has low manufacturing cost. Metal is selected to prepare the motor cover to ensure the heat dissipation efficiency of the motor cover and to ensure the heat dissipation of the driving motor inside the motor cover.

[0063] In addition, by placing the drive motor independently outside the drive housing 1, it is possible to visually observe or find out whether condensation or moisture is formed on the drive motor and the motor cover, and if so, it can be cleaned in time and conveniently. The drive motor placed outside the drive housing 1 is protected by the motor cover, and some waterproof measures can be applied to the drive motor and the motor cover, such as adding a waterproof layer or adding a waterproof baffle.

[0064] like Figure 2 As shown, the transmission mechanism 4 includes a primary reduction transmission assembly, a secondary reduction transmission assembly and a tertiary transmission assembly which are sequentially connected. The primary reduction transmission assembly is connected to the power input mechanism 2, and the tertiary transmission assembly is connected to the power output shaft 31. The transmission mechanism 4 adopts a two-stage reduction to reduce the output speed of the drive motor so that it meets the working requirements of the ice maker for preparing chewable ice.

[0065] like Figure 2 As shown, the primary reduction transmission assembly includes a worm 41 that is transmission-connected to the power input mechanism 2 and a worm wheel 42 that meshes with the worm 41. The primary reduction transmission assembly adopts a worm gear transmission structure to achieve primary reduction, a large reduction ratio, and a good retrieval effect. At the same time, the worm gear meshing structure is compact, which reduces the overall volume of the ice skate drive device 10. Furthermore, the worm gear transmission structure is adopted, and the transmission is stable and the transmission working noise is low. In addition, the primary reduction transmission assembly adopts a worm gear transmission structure, and the worm is directly connected to the motor shaft of the drive motor for transmission, which increases the distance between the worm wheel and the drive motor, and realizes the operation and purpose of setting the drive motor outside the drive housing 1.

[0066] like Figure 1 As shown, a worm housing 11 is added to the outside of the worm to protect the worm 41. At the same time, the structure and shape of the worm housing 11 adapt to the worm structure, thereby reducing the overall volume of the ice skate drive device 10.

[0067] like Figure 2 As shown, the two-stage reduction transmission assembly includes a pinion 43 and a large gear 44 meshing with the pinion 43, and the pinion 43 is coaxially fixed to the worm gear 42. The pinion 43 drives the large gear 44 to achieve two-stage reduction, and the outer diameter of the pinion 43 is smaller than the outer diameter of the worm gear, which further reduces the overall size of the ice skate drive device 10, especially the size along the axial direction of the power output shaft 31, and also facilitates the layout and installation of various transmission components in the drive housing 1.

[0068] like Figure 2 As shown, the three-stage transmission assembly includes a planetary gear assembly. The planetary gear assembly includes a sun gear 46, a plurality of planetary gears 47, a planetary carrier 48 and an outer fixed inner gear ring 49. The sun gear 46 is driven by a large gear 44. The planetary gears 47 are meshed with the sun gear 46 and the outer fixed inner gear ring 49 and are installed on the planetary carrier 48. The power output shaft 31 is coaxially fixed to the planetary carrier 48. The planetary gear assembly has a small size, light weight, a large transmission ratio, a compact structure, a high load-bearing capacity, and a high transmission power. It can achieve a large torque output and meets the requirements of ice skates for preparing chewing ice.

[0069] In one embodiment, the power output shaft 31 and the planet carrier 48 are integrally formed, which simplifies the installation of the power output shaft 31 and the planet carrier 48. The integral forming is generally performed by casting and then mechanical finishing, so that the power output shaft 31 and the planet carrier 48 are reliably connected and the power output shaft 31 and the planet carrier 48 are coaxially arranged.

[0070] To further ensure the stability of the internal transmission of the transmission mechanism 4, a mounting shaft 45 is fixedly connected to the large gear 44. The mounting shaft 45 is provided with a keyway hole 50 coaxial with the mounting shaft. A spline shaft 51 is inserted into the keyway hole 50, and the sun gear 46 is fixedly connected to the spline shaft 51.

[0071] like Figure 3 The large gear 44 and the mounting shaft 45 are integrally formed, and then during assembly, the spline shaft 51 is inserted into the keyway hole 50 to achieve the connection between the mounting shaft 45 and the spline shaft 51. The spline shaft 51 obtains the same angular velocity as the large gear and rotates synchronously, so the connection is reliable and the transmission is stable. Figure 4 The sun gear is fixedly connected to the spline shaft 51, realizing the motion transmission between the large gear 44 and the sun gear, and the transmission is stable and reliable. At the same time, the implementation of this solution simplifies the internal structure, installation and layout of the ice blade drive device 10, making the power transmission of the ice blade drive device reliable and stable.

[0072] To facilitate further understanding of the ice skate driving device 10 by those skilled in the art, Figure 5 As shown, the installation positions of the ice blade drive device 10 and the ice blade 103 are shown. The ice blade drive device and the ice blade 103 are detachably connected, and the ice blade drive device 10 is ensured to be located above the ice making box 102. Figure 5 As shown, the power output shaft 31 of the ice blade driving device extends downward and is detachably connected to the ice blade driving end 107 of the ice blade 103, and the ice blade driving end 107 is inserted into the connecting hole 32 on the power output shaft 31 to achieve connection.

[0073] like Figure 5 An ice maker includes the aforementioned ice blade driving device 10, and also includes an ice maker body 101, an ice box 102 and an ice blade 103. The ice box 102 is installed in the ice maker body 101 and placed below the ice blade driving device 10. The ice blade 103 is placed in the ice box 102, and the driving end of the ice blade 103 extends from the upper side of the ice box 102. The ice blade driving device 10 is detachably installed with the ice maker body 101 and detachably connected with the driving end of the ice blade 103. Ice cubes are obtained by making ice in the ice box 102. The ice blade 103 rotates under the drive of the ice blade driving device 10, chews and transports the smooth ice upward, and the smooth ice is discharged from the ice box ice guide port 104 on the ice box 102 and enters the ice storage box 105.

[0074] In order to facilitate the installation of the mounting surface on the ice blade driving device 10 with the ice blade when the ice blade driving device 10 is detachably connected to the ice blade, a plurality of connecting posts 106 are provided on the top cover of the ice box 102, and the connecting posts 106 are adapted to the connecting blind holes 13 on the mounting surface 12. When the ice blade driving device 10 is detachably connected to the ice blade, the connecting posts 106 are also synchronously inserted into the connecting blind holes 13 on the mounting surface 12, so as to realize the detachable installation of the ice blade driving device 10 and the ice box 102. Alternatively, a plurality of connecting posts are provided on the outer side of the ice box 102 on the ice maker body, and they can also be connected with the connecting blind holes. The connecting posts are cylindrical, and the connecting blind holes are connected to the cylindrical blind holes, so as to release the kinematic pair when the connecting posts are connected with the connecting blind holes as much as possible, so as to avoid the problem of over-positioning when the ice blade driving device 10 is detachably connected to the ice box 102, so as to facilitate the detachable connection of the ice blade driving device 10 and the ice box 102.

[0075] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
