Description

A drive unit for a cold drink machine Technical Field

[0001] This utility model relates to the field of cold drink machine equipment technology, and in particular to a drive body for a cold drink machine. Background Technology

[0002] Existing beverage cooler equipment, especially those used for making smoothies, generally includes an ice-making chamber for forming and storing the smoothie, and an evaporator located within the ice-making chamber. Based on usage requirements, evaporators are designed to be either horizontally or vertically mounted. Evaporators typically have a heavy structure with numerous copper tubes. For beverage coolers with horizontally mounted evaporators, and given that the main body of the cooler is generally a shell structure, the existing conventional screw connections can easily cause the evaporator to sag under excessive load during long-term use. This can lead to gaps at the joints when the ice-making chamber is fitted onto the evaporator for a sealed installation, preventing a perfect seal.

[0003] On the other hand, existing beverage coolers are generally equipped with scrapers for dispensing slushies, and the ice-making chamber is detachable, which creates safety hazards.

The bottom of the end cap groove is provided with a support limiting hole that is adapted to the bearing plug, the transverse support rib and the longitudinal support rib.

[0010] As an improvement to the above solution, the evaporation port of the evaporation end cap is provided with a docking ring for inserting into the ice-making chamber, and the docking ring is fitted with a sealing ring.

[0011] As an improvement to the above solution, a sealing groove is provided on the inner side of the docking ring so that the inner flange of the sealing ring can be fitted in.

[0012] As an improvement to the above solution, the sealing groove is provided with an evaporation connecting column for connecting and fixing the evaporator, and the evaporation connecting column is provided with an evaporation connecting hole for threaded connection.

[0013] As an improvement to the above solution, the sealing groove is ring-shaped and divided into an upper ring groove and a lower ring groove, with the lower ring groove located below the upper ring groove;

[0014] The inner wall of the lower annular groove has multiple side wall openings, so that the inner flange can be squeezed into the side wall openings when it is compressed and deformed.

[0015] As an improvement to the above solution, the evaporator end cap and the end head are provided with corresponding pull-out connection holes, and the edge of the sealing ring is provided with elastic connecting strips to pass through the pull-out connection holes of the evaporator end cap and the end head in sequence.

[0021] Implementing this utility model has the following beneficial effects:

[0022] This utility model embodiment discloses a drive body, including a drive housing and an evaporation end cover, wherein the evaporation end cover is provided with an evaporation port for internal components of the evaporator to pass through;

[0023] The drive housing includes a head for mounting the evaporator and a control unit. The head has an end cap groove that matches the evaporator end cap for insertion of the evaporator end cap. The bottom of the end cap groove has a device port corresponding to the evaporation port. Therefore, in assembly and production, the evaporator and the evaporator end cap can be connected first, and then the evaporator and the drive housing can be initially installed by inserting the evaporator end cap into the end cap groove. After that, only the screw tightening process is required.

[0024] Furthermore, the evaporation end cap is provided with a protrusion for contacting the ice-making cavity. The protrusion is provided with a contact switch and a trigger stroke hole corresponding to the contact switch, so as to guide an external trigger to contact and trigger the contact switch.

[0027] Figure 2 is an exploded structural diagram of the drive mechanism of this utility model;

[0028] Figure 3 is an exploded view of the drive mechanism of this utility model from another angle. Detailed Implementation

[0029] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Referring to Figures 1, 2 and 3, this embodiment of the present invention provides a drive body, including a drive housing for mounting drive equipment and an evaporation end cover 1 for docking and mounting an evaporator. The evaporation end cover 1 is provided with an evaporation port 1a for internal components of the evaporator to pass through.

[0031] The drive housing includes a head 2 for mounting the evaporator and a control unit 3 for mounting control devices. The head 2 is provided with an end cap groove 21 adapted to the evaporator end cap 1 for the insertion of the evaporator end cap 1. The bottom of the end cap groove 21 is provided with a device port 2a corresponding to the evaporation port 1a.

[0032] The evaporation end cap 1 is provided with a protruding part 11 for contacting the ice-making cavity. A contact switch 4 is provided in the protruding part 11. The protruding part 11 is provided with a trigger stroke hole 111 corresponding to the contact switch 4, so as to guide an external triggering element to contact and trigger the contact switch 4.

[0033] The evaporation end cap 1 is provided with a bearing plug 12 for connecting with the end head 2. The bearing plug 12 is provided with a transverse support rib 121 and a longitudinal support rib 122. The bottom of the end cap groove 21 is provided with a support limiting hole 211 that is adapted to the bearing plug 12, the transverse support rib 121 and the longitudinal support rib 122.

[0034] Specifically, the evaporation port 1a of the evaporation end cap 1 is provided with a docking ring 13 for inserting into the ice-making chamber. The docking ring 13 is fitted with a sealing ring 5 to improve the sealing performance of the ice-making chamber. The contact switch 4 is prior art, and its structure and principle will not be described in detail here.

[0035] Furthermore, since the ice-making cavity and the docking ring 13 need to be disassembled and cleaned during daily use, and the sealing ring 5 provided on the docking ring 13 needs to be embedded in the interface of the ice-making cavity, a pulling force will be generated on the sealing ring 5 during disassembly, causing the sealing ring 5 to fall off. Therefore, a sealing groove 131 is provided on the inner side of the docking ring 13 to allow the inner flange 51 of the sealing ring 5 to fit in, thereby greatly improving the anti-detachment property of the sealing ring 5.

[0036] The sealing groove 131 is provided with an evaporation connecting column 132 for connecting and fixing the evaporator. The evaporation connecting column 132 is provided with an evaporation connecting hole for threaded connection. Therefore, the outer shell of the evaporator can be bolted through the evaporation connecting column 132. Preferably, the evaporation connecting hole is a threaded hole.

[0037] Furthermore, the sealing groove 131 is annular in shape and is divided into an upper annular groove and a lower annular groove, with the lower annular groove located below the upper annular groove;

[0038] The inner wall of the lower annular groove has multiple side wall openings 133, allowing the inner flange 51 to deform under pressure and be squeezed into the side wall openings 133. This design allows for the selection of a slightly larger sealing ring 5, facilitating its installation. When installed in the evaporator, the outer wall of the evaporator compresses the sealing ring 5, causing it to deform and partially insert into the side wall openings 133, thus hooking into the lower annular groove and preventing it from detaching.

[0039] Furthermore, to improve the anti-detachment performance of the sealing ring 5 and enhance the connection between the evaporator end cap 1 and the end head 2, corresponding pull-out connection holes c are provided on the evaporator end cap 1 and the end head 2. Elastic connecting strips 6 are distributed along the edge of the sealing ring 5 to pass sequentially through the pull-out connection holes c of the evaporator end cap 1 and the end head 2. Each elastic connecting strip 6 has a tapered head 61 for inserting into the pull-out connection hole c to prevent it from detaching from the hole c. Therefore, the contractility of the elastic connecting strip 6 can tighten the sealing ring 5, the evaporator end cap 1, and the end head 2 together.

[0040] Preferably, the pull-out connection hole c of the evaporator end cap 1 is distributed around the upper annular groove and is located above the side wall opening 133.

[0041] To improve the stability of the initial installation between the evaporator end cap 1 and the end head 2, the evaporator end cap 1 is provided with a positioning auxiliary connecting post 14, and the end head 2 is provided with a positioning groove 22 that is adapted to the positioning auxiliary connecting post 14 for insertion of the positioning auxiliary connecting post 14.

[0042] The positioning grooves 22 are distributed on both sides of the device port 2a, and are both located below the support limiting hole 211. This ensures that the installation connection between the evaporator end cap 1 and the end head 2 is uniformly supported and connected.

[0043] To facilitate initial positioning and installation of the drive unit during the overall assembly of the beverage machine, the control unit 3 and the end head 2 are interconnected and form an L-shape, using the stepped structure created by the L-shape for initial positioning and installation. The bottom of the end head 2 is provided with a device connection port 23 for external devices or wiring to pass through.

[0044] To ensure the portability of the final assembled beverage cooler, the drive housing has pivots 24 on both sides for mounting handles, and a gripping groove 25 on its top surface. Therefore, in actual production assembly, appropriate handles 7 can be installed according to specific production needs. Furthermore, to address extreme handle designs, such as handles that fit snugly against the top surface of the drive housing, making them difficult to grip, the gripping groove allows a hand to be inserted into the groove 25 to lift the handle 7 when it is snug against the top surface of the drive housing.

[0045] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
