A coffee machine brewing module

Abstract

This utility model discloses a brewing module for a coffee machine, including a housing fixed to the coffee machine body. A flow valve and a water pump switch are installed inside the housing. Above the flow valve is a drive mechanism that drives the flow valve stem and triggers the water pump switch. The drive mechanism drives the valve stem to adjust the flow valve and control the flow rate of the brewing water, while simultaneously driving a trigger element to rotate with a turntable and trigger the water pump switch to turn on the water pump. A limiting bracket is provided inside the housing, with a downward recess forming a limiting groove. The flow valve is placed in the limiting groove and can move up and down. The limiting groove restricts the circumferential movement of the flow valve. When the drive mechanism drives the flow valve stem, the limiting groove of the limiting bracket restricts the circumferential rotation of the flow valve body, while the valve body can also move up and down within the limiting groove to counteract the displacement caused by the rotation of the valve stem. Therefore, a control module can be installed on the top of the brewing module, which can integrate a data display interface and a smart operation interface, integrating the operation of the coffee machine into the brewing module.

Description

Technical Field

[0001] This utility model belongs to the field of coffee machines, specifically a coffee machine brewing module. Background Technology

[0002] A coffee machine is a device used to make coffee, and it has now become a common household appliance. During the coffee-making process, the water volume, pressure, and other settings all affect the taste of the coffee. Therefore, the brewing module of a coffee machine is equipped with a flow control valve to regulate the flow rate, thereby controlling parameters such as water volume and pressure. Previously, using a coffee machine required operating a flow control switch and activating the water inlet switch. For ordinary users who were already familiar with coffee machines, this lack of integration and complexity made it difficult for them to easily learn and use.

[0003] In addition, coffee machines are currently operated primarily through mechanical switches, which are scattered and the data display interface is not prominently positioned, making them inconvenient for users. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a brewing module for a coffee machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A brewing module for a coffee machine includes a housing fixedly mounted to the coffee machine body. The housing has a top opening, and a control module is installed on the top opening cover. A flow valve and a water pump switch are installed inside the housing. Above the flow valve is a drive mechanism for driving the flow valve stem and triggering the water pump switch. The drive mechanism includes a turntable, which is rotatably connected inside the housing and has a transmission hole in its center that is drively connected and fixed to the valve stem. A transmission rod extends radially through the housing from the turntable. A trigger element is also provided on the turntable. The water pump switch is located on the travel path of the trigger element. The transmission rod drives the turntable to rotate, and through the transmission hole drives the valve stem to adjust the flow valve and control the flow rate of the brewing water. At the same time, it drives the trigger element to follow the rotation of the turntable and trigger the water pump switch to turn on the water pump. A limiting bracket is provided inside the housing. The limiting bracket is recessed downward to form a limiting groove. The flow valve is placed in the limiting groove and can move up and down. The limiting groove can restrict the circumferential movement of the flow valve.

[0007] The control module includes a bottom shell support, a screen, and an electronic control unit. The screen and the electronic control unit are arranged inside the bottom shell support, and the bottom shell support is fixedly installed to the housing.

[0008] The bottom of the base support is also provided with a guide post that is rotatably connected to the turntable. There are two guide posts arranged symmetrically. The turntable is provided with two symmetrical arc-shaped grooves for the guide posts to pass through. The arc-shaped grooves are arranged concentrically with the center of the turntable. The turntable is rotatably connected in the housing through the cooperation of the arc-shaped grooves and the guide posts. The length of the arc-shaped grooves limits the rotation stroke of the turntable.

[0009] An elongated through-slot is formed between the housing and the control module for the transmission rod to pass through. An arc-shaped guide arm extends laterally on the transmission rod, and a guide groove is formed inside the elongated through-slot to clamp the arc-shaped guide arm.

[0010] The arc-shaped guide arms are symmetrically arranged on both sides of the transmission rod, and the length of the arc-shaped guide arm on one side is greater than the length of the elongated through groove.

[0011] The drive mechanism includes a handle, which is connected to the outer end of the transmission rod.

[0012] The bottom of the base bracket is also provided with a mounting seat for installing the water pump switch. The mounting seat includes clamping claws on both sides of the water pump switch and a connecting post located between the clamping claws. The water pump switch is clamped between the two clamping claws and fixed to the connecting post with screws, so that the water pump switch is arranged in the horizontal direction of the turntable.

[0013] The limiting bracket is formed by bending sheet metal, the limiting groove is through on both sides, and the flow valve is provided with an inlet connector and an outlet connector facing the through side of the limiting groove.

[0014] The side of the housing is provided with a connecting seat for connecting to the coffee machine body. One of the through sides of the limiting groove is arranged facing the connecting seat. The water inlet and water outlet connectors on the flow valve are arranged on the through side facing the connecting seat.

[0015] The inner side of the housing is symmetrically provided with two mounting platforms for mounting and fixing limit brackets. The limit brackets have mounting holes on both sides and are fixed to the bottom of the two mounting platforms by through screws. The height of the two mounting platforms is lower than that of the turntable.

[0016] The beneficial effects of this utility model are as follows: This utility model has a drive mechanism on the brewing module that can simultaneously operate the flow valve and the water pump switch. The flow valve is installed on the drive mechanism and is provided with a limiting bracket to limit the flow valve circumferentially. When the drive mechanism drives the valve stem of the flow valve, the limiting groove of the limiting bracket restricts the circumferential rotation of the valve body. At the same time, the valve body can also move up and down in the limiting groove to counteract the displacement caused by the rotation of the valve stem. Thus, a control module can be provided on the top of the brewing module. The control module can integrate a data display interface and an intelligent operation interface, so that the operation of the coffee machine is integrated into the brewing module.

[0023] Reference Figures 1 to 5 A coffee machine brewing module includes a housing 1 fixedly mounted to the coffee machine body. A flow valve 4 and a water pump switch 5 are installed inside the housing 1. Above the flow valve 4 is a drive mechanism 3 that drives the flow valve stem 41 and triggers the water pump switch 5. The flow valve 4 operates by using the valve stem 41 to drive the valve core and control the inlet and outlet water flow of the valve seat. This is common existing technology and will not be described in detail here. The water pump switch 5 is a micro switch or proximity switch, also existing technology, and will not be further explained.

[0024] The machine casing 1 has a top opening and a control module 2 is provided on the top opening cover. The control module 2 includes a bottom shell support 21, a screen 22, and an electronic control unit. The bottom shell support 21 is fixedly installed on the machine casing 1. The screen 22 and the electronic control unit are arranged inside the bottom shell support 21. The user operates other modules of the coffee machine by operating the screen 22 and then by operating the electronic control unit, such as the water temperature module. At the same time, the electronic control unit can also collect information from the coffee machine and display it on the screen 22 so that the user can understand the current working status of the coffee machine.

[0025] The drive mechanism 3 includes a turntable 6 and a handle 7. The turntable 6 is rotatably connected inside the housing 1 and has a transmission hole 61 in the middle that is fixedly connected to the valve stem 41, so that the flow valve 4 is installed on the drive mechanism. The turntable 6 extends radially through the transmission rod 62 of the housing 1. The handle 7 is connected to the outer end of the transmission rod 62. The turntable 6 is also provided with a trigger 63. The water pump switch 5 is set on the travel path of the trigger 63. When the user pushes the handle 7, the turntable 6 is rotated through the transmission rod 62, and the valve stem 41 is driven through the transmission hole 61 to adjust the flow valve 4 and control the flow rate of the brewing water. At the same time, the trigger 63 is driven to follow the rotation of the turntable 6 to trigger the water pump switch 5 to turn on the water pump to supply water for brewing, so that the coffee machine can brew coffee.

[0026] Since the flow valve 4 is mounted on the drive mechanism, a limiting bracket 9 is provided inside the base 1. The limiting bracket 9 is recessed downward to form a limiting groove 91. The flow valve 4 is placed in the limiting groove 91 and can move up and down. The limiting groove 91 restricts the circumferential movement of the flow valve 4. That is, the valve seat of the flow valve 4 is restricted from circumferential movement within the limiting groove 91 to prevent it from rotating and shifting under the drive of the valve stem 41 to achieve relative movement between the valve core and the valve seat, thereby changing the inlet and outlet water flow. Furthermore, since the valve seat of the flow valve 4 moves up and down within the limiting groove 91 to offset the displacement caused by the rotation of the valve stem, it will not affect the control module arranged on the top of the machine casing. At this time, the operation of the coffee machine is integrated into the brewing module, making it more convenient for users.

[0027] Specifically, the limiting bracket 9 is formed by bending sheet metal. The limiting groove 91 is open on both sides. The flow valve 4 is equipped with an inlet connector 42 and an outlet connector 43, which are arranged facing the open side of the limiting groove 91. This allows the limiting groove 91 to not restrict the up and down movement of the flow valve 4. Furthermore, when maintenance personnel perform repairs, they only need to disassemble the control module 2, and the casing can easily be removed along with the flow valve 4, making maintenance very convenient. The casing 1 has a connecting seat 11 on its side for connecting to the coffee machine body. One of the open sides of the limiting groove 91 is arranged facing the connecting seat 11. The inlet connector 42 and the outlet connector 43 on the flow valve 4 are arranged on the open side facing the connecting seat 11 for better connection with the water pipe introduced from the coffee machine. Furthermore, the limit bracket 9 is installed through two symmetrically arranged mounting platforms 12 inside the housing 1. The limit bracket 9 has mounting holes 92 on both sides, and screws are passed through the mounting holes 92 to fix it to the bottom of the two mounting platforms 12 respectively. The two mounting platforms 12 are set at a height lower than the turntable 6, that is, the support is suspended below the turntable 6, which is conducive to the placement and removal of the flow valve 4.

[0028] In addition, in this preferred embodiment, the turntable 6 and the water pump switch 5 are connected and installed on the control module 2. When adjusting the stroke of the trigger 63, the user can remove the control module 2 from the housing 1 for external operation, which is more convenient. Specifically, the bottom of the bottom shell bracket 21 is also provided with a guide post 23 that is rotatably connected to the turntable 6, and two guide posts are symmetrically arranged. The turntable 6 is provided with two symmetrical arc-shaped grooves 64 for the guide post 23 to pass through. The arc-shaped grooves 64 are arranged concentrically with the center of the turntable 6. The turntable 6 is rotatably connected in the housing 1 through the cooperation of the arc-shaped grooves 64 and the guide post 23. The length of the arc-shaped grooves 64 limits the rotation stroke of the turntable 6. The end point of this rotation stroke is the trigger position of the trigger 63 and the water pump switch 5, thereby preventing the turntable 6 from rotating too far and ensuring that the trigger 63 stably triggers the water pump switch 5. The bottom of the base bracket 21 is also provided with a mounting seat 24 for installing the water pump switch 5. The mounting seat 24 includes clamping claws 241 on both sides of the water pump switch 5 and a connecting post 242 located between the claws 241. The water pump switch 5 is clamped between the two claws 241 and fixed to the connecting post 242 with screws, arranging the water pump switch 5 in the horizontal direction of the turntable 6, while the trigger 63 is arranged on the radial surface of the turntable 6. The arrangement of the trigger 63 is set according to the type of water pump switch 5, such as... Figure 3 , Figure 4 As shown, when the water pump switch 5 is a micro switch, the trigger 63 is a boss integrally formed on the radial surface of the turntable 6. The boss contacts and pushes the trigger rod of the micro switch, thereby triggering the water pump switch 5 to open. Alternatively, the water pump switch 5 can also be a proximity switch, and the trigger 63 can be a metal part (not shown in the attached figure) mounted on the radial surface of the turntable 6. The proximity switch senses the magnetism of the metal part and triggers the water pump switch 5 to open.

[0029] Furthermore, an elongated through-slot 8 is formed between the housing 1 and the control module 2 for the transmission rod 62 to pass through. This elongated through-slot 8 is formed simultaneously with the top opening of the housing 1 covered by the control module 2, facilitating the removal and disassembly of the drive mechanism 3 along with the control module 2. An arc-shaped guide arm 65 extends laterally from the transmission rod 62. A guide groove 81 is formed inside the elongated through-slot 8 to clamp the arc-shaped guide arm 65. The cooperation between the guide arm and the guide groove 81 makes the rotation of the turntable 6 more stable and the operation of the handle 7 easier. Moreover, the arc-shaped guide arms 65 are symmetrically arranged on both sides of the transmission rod 62, and the length of one side of the arc-shaped guide arm 65 is greater than the length of the elongated through-slot 8. This means that the arc-shaped guide groove 81 can block the area behind the elongated through-slot 8, preventing debris from entering the housing 1 through the elongated through-slot 8.
