Technical field

The invention relates to an ice cream device, in particular to a compact integrated ice cream puffing pump and an ice cream machine.

Background technique

Ice cream puffing pump is an important part of ice cream machine. It has various pumps such as gas mixing pump, air pump, gear pump, piston pump and peristaltic pump. Although the specific pump body structure is different, it is used to realize air and ice cream liquid raw materials. Puffing.

Although the above-mentioned ice cream puffing pumps can all realize the ice cream puffing function, the various pumps have the following defects separately or separately:

(1) The gas mixing pump combines the two parts of the material pump and the air pump, and connects the air output pipe of the air pump and the output pipe of the material pump, and then feeds the ice cream material into the freezing cylinder.

The Chinese patent document No. 201610223532.0 discloses a puffed composite pump device for an ice cream machine, comprising a material pump and a gas pump, wherein the material pump, the air pump and the mixing chamber in the expanded composite pump are independent components, and the split body is used. design. The composite pump has the advantages of low cost and high expansion rate, and has the disadvantages of many defects such as complicated orange structure, high assembly requirements, and complicated expansion rate adjustment operation. Moreover, the material pump and the air pump in the above-mentioned ice cream puffing pump and the mixing part are evenly installed inside the body of the ice cream machine, and since the puffing pump needs to be cleaned frequently, the hygienic safety cannot be ensured. The puffing pump built in the fuselage is time-consuming and laborious to disassemble each time, and there is a problem of inconvenient washing and dismounting, and serious food safety hazards are generated.

(2) The air pump is to inject air into the freezing cylinder through the air pump, and the air and the ice cream material are mixed in the freezing cylinder. The Chinese patent document No. 201210245076.1 discloses a pneumatic ice cream discharge device, including a cylinder. Since the freezing cylinder needs to be fed, the feed port is open, and air entering from the air pump will emerge from the feed port. The advantage is cost, simple structure, and the disadvantage is that the expansion rate is low, difficult to control, and will have an impact on the feed.

(3) The gear pump drives the driving gear and the driven gear through the motor to engage the movement. The ice cream material is sucked in and mixed with the air sucked in at the same time, and then injected into the freezing cylinder. The Chinese patent document No. 02287214.0 discloses an expansion pump device of an ice cream machine in which a externally engaged rotating gear is mounted. The puffing pump device has the advantages of high puffing rate and relatively simple structure, and has the disadvantages of high cost, high noise, high processing precision, mechanical wear, and difficulty in controlling the puffing rate.

(4) The piston pump is driven by the motor to drive the eccentric wheel to push the piston to reciprocate, suck the ice cream material, mix the air and then inject into the freezing cylinder. Chinese patent document No. 201020240047.2 discloses a reciprocating The gas-liquid mixing slurry expansion pump has an eccentric shaft of a pump body, a piston and a transmission piston. The puffing pump has the advantages of high puffing rate, high cost, high processing precision, complicated structure, and inconvenience in disassembly and cleaning.

Therefore, the above-mentioned conventional ice cream machine puffing pump generally has defects such as complicated orange structure, high processing precision and assembly requirements, inconvenient washing and dismounting, complicated operation of adjusting the expansion rate, and inaccurate control of the expansion rate, and needs improvement.
