Description

Technical Field

[0001] This utility model relates to the field of industrial equipment technology, and in particular to a pneumatic pressure controller. Background Technology

[0002] A pneumatic pressure controller is an automated device used to precisely regulate and maintain gas pressure, widely used in many fields such as industrial manufacturing, medical equipment, aerospace, meteorological observation, and scientific research. This instrument typically consists of core components such as a pressure sensor, control valve, controller, and display interface. It can monitor the system pressure in real time and compare it with a preset target value. Then, it achieves closed-loop control by automatically adjusting the intake or exhaust volume, ultimately stabilizing the system pressure within the set range.

[0003] In specific application scenarios, pneumatic controllers are often deployed on laboratory benches, test platforms, or various prototypes to support scientific research experiments or product performance testing. These scenarios typically feature strong mobility, sharing, and temporary characteristics, thus requiring pneumatic controllers to be able to flexibly change working locations to adapt to different usage needs.

[0004] However, traditional pneumatic controllers are mostly fixed by mounting holes on the bottom and M3 or M4 screws, requiring them to be secured to a bracket or cabinet. Disassembly also requires removing all screws one by one before the unit can be moved. This type of installation and disassembly is cumbersome, time-consuming, labor-intensive, and affects user convenience and work efficiency. Utility Model Content

[0005] To address the problems mentioned above in the background art, this utility model provides a pneumatic control device that is easy to install and disassemble.

[0006] The solution adopted by this utility model to solve its technical problem is: a pressure controller, including a housing, a main board inside the housing, and a pressure sensor and a pump electrically connected to the main board; a power socket, a pressure measuring interface and a communication interface connected to the main board are provided on the side of the housing, and a display screen and control buttons electrically connected to the main board are provided on the top surface of the housing.

[0007] The air pressure measuring interface is connected to the air pressure sensor through an air pipeline and is used to detect the air pressure of the external environment. At least one solenoid valve is electrically connected to the main board and is used to control the opening and closing of the air pipeline.

[0008] The bottom of the housing is provided with a magnetic groove, and a magnetic block is embedded in the magnetic groove. The magnetic block is made of permanent magnet material, and the side of the magnetic block near the housing is wrapped with a magnetic shielding material.

[0009] Furthermore, the control buttons include a power switch, a mode switch, a pressure setting increment button, and a pressure setting decrement button.

[0010] Furthermore, the housing includes a top cover and a bottom cover. A module compartment is detachably connected inside the bottom cover. An expansion function module is provided in the module compartment. The module compartment is electrically connected to the motherboard. A female connector is provided in the module compartment. The expansion function module is provided with a male connector that matches the female connector. The module compartment and the expansion function module are electrically connected through the connection between the female connector and the male connector.

[0011] Furthermore, the extended function module is a wireless communication module, which is either a Wi-Fi module or a Bluetooth module.

[0012] Furthermore, the extended function module is a micro SD card slot.

[0013] Furthermore, the extended functional module is a secondary battery.

[0014] Furthermore, the bottom shell is provided with a guide rail inside, the side of the module compartment is provided with a groove that matches the guide rail, and the beginning of the guide rail is provided with a locking block that restricts the movement of the module compartment.

[0015] Furthermore, the end of the guide rail is provided with a signal contact, and the groove is provided with a metal contact pad corresponding to the signal contact. When the module compartment slides to the end of the bottom shell, the signal contact and the metal contact pad in the groove form an electrical contact.

[0016] In summary, the beneficial effects of this utility model are as follows:

[0017] 1. This application provides a magnetic block at the bottom of the housing of the pneumatic controller, which allows the pneumatic controller to be directly magnetically fixed to a bracket or external iron equipment, making it convenient for operators to install and remove the pneumatic controller housing. In addition, the side of the magnetic block near the housing is also wrapped with a magnetic shielding material to prevent the magnetic block from affecting the operation of the internal components of the pneumatic controller.

[0018] 2. The bottom shell of the air pressure controller has a detachable module compartment. The module compartment can be used to install wireless communication modules, micro SD card slots or auxiliary batteries as needed. The above design effectively enhances the adaptability of the air pressure controller.

Unless otherwise stated, "a plurality of" means two or more.

[0029] Unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figures 1 to 4 As shown, a pneumatic pressure controller includes a housing made of a metal material, which has good thermal conductivity and high density. Specifically, the housing includes a top cover 1 and a bottom cover 2. The pneumatic pressure controller in this embodiment adopts a sandwich structure. The top cover 1 is the display and control area; the middle layer inside the housing contains the main board 9 and the core circuit; the bottom layer contains the pneumatic circuit module, the module compartment 3, and the expansion function module 31.

[0031] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, the housing contains a main board 9, which is electrically connected to a pressure sensor and an air pump; the side of the housing contains a power socket 4, a pressure measuring interface 5, and a communication interface 6 connected to the main board 9; the top of the housing contains a display screen 7 and control buttons 8 electrically connected to the main board 9.

[0032] The air pressure measuring interface 5 is connected to the air pressure sensor via an air passage pipe to detect the air pressure of the external environment. At least one solenoid valve is electrically connected to the main board 9, and the solenoid valve is used to control the opening and closing of the air passage pipe. In this embodiment, the solenoid valve is a two-position, normally closed miniature solenoid valve, used to quickly cut off or establish a target air passage.

[0033] like Figure 3 As shown, the bottom of the shell is provided with four symmetrical cylindrical magnetic slots, and magnetic blocks 21 are embedded in the magnetic slots. The magnetic blocks 21 are made of neodymium iron boron permanent magnets.

[0034] Among them, the magnetic block 21 is wrapped with a magnetic shielding material 22 on the side near the shell. The magnetic shielding material 22 is permalloy. The permalloy is fixed to the side of the magnetic block 21 facing the shell and the four sides by conductive adhesive, which can effectively limit the magnetic field to the bottom and prevent the magnetic field of the magnetic block 21 from causing signal interference to the sensitive air pressure sensor and the main board 9 circuit inside the shell.

[0035] With the above design, users can instantly attach the pneumatic controller to any iron surface, such as a cabinet, laboratory bench, or equipment casing, without the need for other fixing tools, thus improving deployment efficiency and flexibility.

[0036] like Figure 2As shown, the control button 8 includes a power switch, a mode switch, a pressure setting increment button, and a pressure setting decrement button. Additionally, the pressure controller in this embodiment is equipped with an alarm light.

[0037] In this embodiment, the bottom shell 2 is detachably connected to a module compartment 3. The module compartment 3 contains an expansion module PCB and an expansion function module 31 electrically connected to the expansion module PCB. The expansion module PCB in the module compartment 3 is electrically connected to the motherboard 9. The module compartment 3 contains a female connector, and the expansion function module 31 contains a male connector that matches the female connector. The module compartment 3 and the expansion function module 31 are electrically connected through the connection between the female connector and the male connector.

[0038] like Figure 2 and Figure 4 As shown, the extended function module 31 is a secondary battery. Through the above design, in the event of an unexpected interruption of the main power supply, the pressure controller can still maintain normal operation or execute a safe shutdown procedure, preventing experimental failure or process interruption.

[0039] Alternatively, the extended function module 31 can be a wireless communication module, such as a Wi-Fi module, a 4G module, or a Bluetooth module. Figure 5 As shown, when the wireless communication module is a Wi-Fi module, a Wi-Fi antenna is provided on the outer wall of the barometric pressure controller, and the Wi-Fi antenna is connected to the module compartment 3 for signal transmission. Through the above design, the barometric pressure controller of this embodiment can achieve network connectivity and wireless data transmission, and communicate with a mobile APP. Furthermore, the extended function module 31 can also be a micro SD card slot, allowing the barometric pressure controller to work independently in locations without network access, such as in the field or on a moving vehicle, and to export data via a card reader after operation.

[0040] like Figure 3 and Figure 4 As shown, the bottom shell 2 has two integrally formed guide rails 23 inside. The cross-section of the guide rails 23 is T-shaped or dovetail-shaped. The side of the module compartment 3 has a groove 32 that matches the guide rails 23. The beginning of the guide rails 23 has a spring-loaded self-resetting locking block 10 that restricts the movement of the module compartment 3. When the module compartment 3 is pushed in along the guide rails 23, its front inclined surface will press down the locking block 10; when it is pushed to the end, the locking block 10 will spring up under the action of the spring and lock into the groove at the front of the module compartment 3, restricting the movement of the module compartment 3. When disassembling, the module compartment 3 can be removed by pressing the locking block 10 with slight force.

[0041] The end of the guide rail 23 is provided with a signal contact 231, and the slide groove 32 is provided with a metal contact pad 321 corresponding to the signal contact 231. In this embodiment, the signal contact 231 is a gold-plated spring pin. When the module compartment 3 slides to the end of the bottom shell 2, the signal contact 231 and the metal contact pad 321 in the slide groove 32 form an electrical contact.

[0042] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
