Description

Technical Field

[0001] The utility model belongs to the technical field of tea drinking machines, in particular to a weighing switch system of a tea drinking machine. Background Art

[0002] As people's living standards improve, their requirements for food are gradually increasing. There are some flavored tea drinks available. After hot tea is chilled, it is poured into prepared juice or milk to form tea drinks to meet people's taste needs. Since hot water is needed to brew tea, the hot tea after brewing generally needs to be cooled to 4-8 degrees Celsius by cooling equipment to reduce the bitterness in the tea. The existing cooling structure generally includes an aluminum ingot and a refrigeration compressor connected to the aluminum ingot. The tea is chilled by injecting the tea into the aluminum ingot and cooling the aluminum ingot.

[0003] However, this refrigeration method has some problems when used: the volume of aluminum ingots is generally large, so as to ensure that more tea can be chilled each time for easy storage and access. When the number of consumers is small, the chilled tea can easily accumulate in the aluminum ingots and be repeatedly refrigerated, thereby increasing energy consumption. If the iced tea is not needed for a long time, the hot tea can be left at room temperature to cool naturally. The natural cooling method is energy-saving and environmentally friendly, and there is no need to use an additional refrigeration compressor to cool the high-temperature tea. Utility Model Content

[0004] In view of this, the present invention provides a weighing switch system for a tea drinking machine to solve the above problems.

[0016] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0017] like Figures 1 to 3 FIG2 is a schematic diagram of the structure of the weighing switch system of the tea drinking machine provided by the present invention. The weighing switch system includes a weighing assembly 10, a cooling assembly 20 connected to the weighing assembly, and a tea dispensing assembly 30 connected to the cooling assembly 20. The weighing switch system of the tea drinking machine also includes other functional modules, such as a control assembly for controlling the activation of the cooling assembly and a distribution box for providing power, etc. These modules are well known to those skilled in the art and will not be described in detail here.

[0018] It should be noted that for the convenience of marking, Figure 2 The ratio is magnified by 1 times.

[0019] The weighing assembly 10 includes an electronic scale 11 , a tea barrel 12 disposed on top of the electronic scale 11 , a hot water outlet pipe 13 inserted into the tea barrel 12 , and a water pump 14 disposed on the hot water outlet pipe 13 .

[0020] The electronic scale 11 is a weight detection device for weighing the tea barrel 12, and is connected to the following controller for control according to the weight change of the tea barrel 12. The details will be described in detail below in conjunction with the relevant components. The tea barrel 12 is made of stainless steel and has a good heat dissipation effect. A tea pouring port 121 is provided on the top of the tea barrel 12, and two handles 122 are symmetrically arranged around the tea pouring port 121. The hot water outlet pipe 13 is inserted into the top of the tea barrel 12, and the end of the hot water outlet pipe 13 is spaced apart from the bottom bracket of the tea barrel 12, so as to ensure that the hot water outlet pipe 13 can extract the tea in the tea barrel 12. The water pump 14 is used to extract the tea in the tea barrel body 11. The extracted tea will flow along the pipeline through the following aluminum ingot 22 and be cooled by the aluminum ingot 22.

[0021] The refrigeration assembly 20 includes a shell 21 , an aluminum ingot 22 disposed on the bottom plate of the shell 21 , a refrigeration compressor 23 disposed on one side of the aluminum ingot 22 , and a plurality of heat dissipation holes 24 opened on the side wall of the shell 21 .

[0022] The shell 21 is used to protect the various components. The shell 21 is a frame structure, which increases the strength of the structure. The aluminum ingot 22 is used to cool the hot tea. When the tea flows through the aluminum ingot 22 along the pipeline, the temperature of the tea drops due to the low temperature of the aluminum ingot 22 itself. The refrigeration compressor 23 can continuously cool the aluminum ingot 22. It should be noted that the cooling principle and structure of the aluminum ingot 22, as well as the structure of the refrigeration compressor 23 and the structure of the refrigeration aluminum ingot 22 are well known to those skilled in the art and will not be repeated here.

[0023] The tea dispensing assembly 30 includes a tea dispensing bin 31 arranged on one side of the shell 21, a metering pump 32 inserted into the side wall of the shell 21, a controller 33 arranged in the tea dispensing bin 31, a control panel 34 arranged on the outer wall of the tea dispensing bin 31, and a tea dispensing nozzle 35 arranged at the bottom of the tea dispensing bin 31.

[0024] The tea outlet bin 31 and the shell 21 are connected to each other, a part of the metering pump 32 is located in the shell 21, and the other part is placed in the tea outlet bin 31, so that the volume of the tea outlet bin 31 can be reduced, making the appearance of the tea outlet bin 31 beautiful.

[0025] The water outlet of the metering pump 32 is connected to the tea outlet 35, and the water inlet of the metering pump 32 is connected to the hot water outlet pipe 13. It should be noted that a cooling pipe is connected between the water inlet of the metering pump 32 and the hot water outlet pipe 13. The cooling pipe is in contact with the aluminum ingot 22 so that the hot water in the cooling pipe is cooled. Since the setting of the cooling pipe is well known to those skilled in the art, and the structure and installation method of the cooling pipe are existing technologies, they will not be repeated here. The metering pump 32 extracts the tea that has been chilled by the aluminum ingot 22 and flows out of the tea outlet 35 in a quantitative manner. The controller 33 is a single-chip microcomputer. The controller 33 is used to cooperate with the control panel 34 to control the opening and closing of the metering pump 32 and the water pump 14. At the same time, it can continuously detect the weighing information of the electronic scale 11 and convert it into a control signal to automatically control the opening and closing of the water pump 14.

[0026] During use, the operator first pours tea into the tea barrel 12. At this time, the electronic scale 11 will weigh the entire weight of the tea barrel 12 and record it as the initial weight. When iced tea needs to be prepared, the operator turns on the water pump 14 through the control panel 34. The water pump 14 continuously pumps tea from the tea barrel 12 and allows the tea to flow through the aluminum ingot 22 for cooling. The electronic scale 11 continues to weigh until the difference between the weight measured by the electronic scale 11 and the initial weight is the same as the preset value. At this time, the controller 33 will control the water pump 14 to turn off. The operation of the refrigeration component 20 will start when the water pump 14 is turned on, and will turn off after a period of time after the water pump 14 is turned off. The opening and closing and control methods of the various components of the refrigeration component 20 during refrigeration are well known to those skilled in the art and will not be repeated here. After the tea is chilled, the controller 33 receives a completion signal from the refrigeration component 20 and issues a prompt through the control panel 34. The operator then manipulates the control panel 34 to cause the metering pump 32 to pump out the chilled tea and allow the chilled tea to flow out from the tea spout 35 .

[0027] Compared with the prior art, the weighing switch system of the tea drinking machine provided by the present invention can continuously detect the weight of the tea barrel 12 through the electronic scale 11. When the weight reduction value of the tea barrel 12 is the same as the preset value, the controller 33 will turn off the water pump 14, thereby achieving the effect of quantitative extraction of tea, thereby avoiding excessive tea accumulation in the aluminum ingot 22 and accelerating the accumulation of tea scale. At the same time, it can also allow the tea to be placed at room temperature for natural cooling before being chilled, reducing energy consumption and being more energy-saving.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
