Abstract
Description
Technical Field
[0001] This utility model relates to the field of milk frothers, and more particularly to a milk frother. Background Technology
[0002] After prolonged use, existing milk frothers may experience damage due to excessive friction in their design, such as the anti-leakage structure between the stirring rod and the milk cup. If the anti-leakage structure or components are not repaired or replaced in time, milk leakage may occur. Furthermore, the milk is heated by the heater during processing, which could scald workers when they pour out the milk foam. Utility Model Content
[0003] In order to overcome the shortcomings mentioned in the background art, this utility model provides a milk frother.
[0004] The technical solution is as follows: A milk frother includes a base, a heater, and a cup; the heater is placed on the base, and a power socket is provided on the base; the heater is provided with a power socket, and the power socket is plugged into the power socket; the cup is installed inside the heater; it also includes a motor, a first connecting shaft, a second connecting shaft, a rotating rod, a baffle, a sealing block, a stirrer, and a collection frame; the motor is bolted to the inside of the base; the first connecting shaft is fixedly connected to the output shaft of the motor; the second connecting shaft is inserted into the first connecting shaft; the rotating rod is spun onto the second connecting shaft; a baffle is fixedly connected to the rotating rod, the baffle passes through the heater and the cup, and is rotatably connected to the heater and the cup; a sealing block is fixedly connected to the baffle, and the sealing block contacts the cup; a stirrer is fixedly connected to the sealing block; a collection frame is installed on the heater.
[0005] Furthermore, the bottom of the cup has a flow guide surface.
[0006] Furthermore, a rubber pad is provided at the part of the sealing block that contacts the cup.
[0007] Furthermore, the inside of the collection box is equipped with an absorbent sponge to absorb liquid that leaks between the cup and the rotating rod.
[0008] Furthermore, the collection box and heater are designed with a quick-release structure, making it easy to clean up any leaked liquid.
[0009] The beneficial effects are as follows: This utility model allows leakage through the gap between the cup, the rotating rod, and the sealing block. The leaked milk will flow down along the rotating rod, then come into contact with the baffle, and then flow into the collection box through the baffle. It will then be absorbed by the water-absorbing sponge inside the collection box. In this way, the leaked milk is stored, preventing it from leaking to the outside and scalding the staff.

Detailed Implementation
[0014] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.
[0015] Example
[0016] A milk frother, such as Figures 1-3 As shown, it includes a base 1, a heater 2, and a cup 3; the heater 2 is placed on the base 1, and the base 1 is provided with a power socket 1001, and the heater 2 is provided with a power socket 2001, and the power socket 1001 and the power socket 2001 are plugged into each other; the cup 3 is installed inside the heater 2.
[0017] It also includes a motor 4, a first connecting shaft 5, a second connecting shaft 6, a rotating rod 7, a baffle 8, a sealing block 9, a stirrer 10, and a collection frame 11; the motor 4 is bolted to the inside of the base 1; the first connecting shaft 5 is fixedly connected to the output shaft of the motor 4; the second connecting shaft 6 is inserted into the first connecting shaft 5; the rotating rod 7 is screwed onto the second connecting shaft 6; the baffle 8 is fixedly connected to the rotating rod 7, the baffle 8 passes through the heater 2 and the cup 3, and is rotatably connected to the heater 2 and the cup 3; the sealing block 9 is fixedly connected to the baffle 8, and the sealing block 9 contacts the cup 3; the stirrer 10 is fixedly connected to the sealing block 9; and the collection frame 11 is installed on the heater 2.
[0018] The bottom of cup 3 has a flow guide surface 3001, which is used to guide the liquid remaining in cup 3.
[0019] A rubber pad is provided at the part of the sealing block 9 that contacts the cup 3 to ensure a tight fit and reduce liquid leakage.
[0020] The collection box 11 is equipped with an absorbent sponge 11001 to absorb the liquid leaking between the cup 3 and the rotating rod 7.
[0021] The collection box 11 and the heater 2 are designed with a quick-release structure to facilitate the cleaning of leaked liquid.
[0022] First, the staff places the milk frother in the desired position, then connects the power supply. Next, the staff pours milk into cup 3, then controls motor 4 to drive the first connecting shaft 5 to rotate, and the first connecting shaft 5 drives the second connecting shaft 6 to rotate.The second connecting shaft 6 drives the connected components to rotate, namely the rotating rod 7, baffle 8, sealing block 9, and stirrer 10. During this process, the milk in cup 3 is stirred by the stirrer 10, that is, the milk is stirred by the high-speed rotation of the stirrer 10. At the same time, the power socket 2001 is powered by the power socket 1001 on the base 1, so that the heater 2 is powered on and runs to heat the milk in cup 3, that is, to form milk foam by stirring the milk in the heated milk box. During the stirring process, since the rotating rod 7 passes through cup 3 and is in a high-speed rotating state when working, some of the milk in cup 3 will leak through the gap between cup 3, rotating rod 7, and sealing block 9. The leaked milk will flow along... The milk flows downwards along the rotating rod 7, then contacts the baffle 8, and then flows through the baffle 8 into the collection frame 11. It is then absorbed by the absorbent sponge 11001 inside the collection frame 11. It should be noted that existing milk frothers, after prolonged use, may suffer damage due to excessive friction caused by the anti-leakage structure between the stirring rod and the milk cup 3. If the anti-leakage structure or components are not repaired or replaced in time, milk leakage will occur. Furthermore, during processing, the milk is heated by the heater 2, which could scald the worker when pouring the milk foam. Therefore, the leaked milk is stored in the above manner to prevent leakage to the outside world. After the worker has filled the cup 3... After the milk foam is poured out, if the cup 3 is not cleaned promptly, some of the residual milk foam will adhere to the sealing block 9 and the stirrer 10. It should be noted that milk foam is relatively viscous compared to milk and needs to be cleaned promptly. Since the milk frother is used in coffee shops, it is often used for other tasks, leading to situations where it is not cleaned in time. If not cleaned for a long time, the milk will dry and adhere to the sealing block 9 and the stirrer 10. Existing stirrers 10 all have a spring structure, further increasing the difficulty of cleaning. However, during the use of this device, because the bottom of the cup 3 has a guide surface 3001, during placement, some of the milk foam remaining on the sealing block 9 and the stirrer 10 will flow along the guide surface 3001 under the influence of gravity. The milk flows to the bottom of cup 3, reducing milk foam adhesion to the sealing block 9 and stirrer 10, making cleaning easier. After multiple uses, the operator can unscrew the second connecting shaft 6 to separate it from the rotating rod 7. Then, the operator can pull out the connected parts through the sealing block 9, namely, the rotating rod 7, baffle 8, and stirrer 10. Next, the operator removes cup 3 from heater 2 and then removes collection frame 11 from heater 2. The operator can then use absorbent sponge 11001 to check for leaks. If a large leak occurs, it needs to be repaired promptly. Finally, the operator cleans cup 3, rotating rod 7, baffle 8, stirrer 10, and collection frame 11 inside the equipment.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
