Description

Technical Field

[0001] The utility model relates to a control system for a moxibustion apparatus, in particular to a control system for a moxibustion apparatus. Background Art

[0002] Moxibustion is a long-standing Traditional Chinese Medicine (TCM) therapy that uses the heat and aroma released by burning mugwort to stimulate acupuncture points on the body, thereby treating diseases and maintaining health. However, traditional moxibustion methods have drawbacks, including reliance on manual operation, difficulty in temperature control, and excessively thick smoke. To address these challenges, moxibustion devices have emerged. Using electronic technology and modern control theory, moxibustion devices automate moxibustion. They precisely control the temperature, duration, and intensity of moxibustion, thereby improving its effectiveness and safety.

[0003] However, the current moxibustion instrument control systems on the market have the following problems, such as poor control accuracy and complicated operation. Therefore, there is an urgent need for a more advanced and intelligent moxibustion instrument control system to meet market demand. Utility Model Content

[0004] The purpose of the utility model is to provide a control system for a moxibustion apparatus, which fundamentally solves the above problems and has the advantages of simple operation and high safety.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the control system for the moxibustion instrument includes an MCU, a charging module, a battery, and an alarm module. The technical points are: the MCU is electrically connected to the charging module, the charging module is electrically connected to the TYPE-C interface module and the battery respectively, the signal output end of the MCU is electrically connected to the exhaust component, the negative pressure pump, the alarm module, and the electromagnetic pressure relief valve respectively, the signal input end of the MCU is electrically connected to the temperature sensor and the pressure sensor respectively, and the pressure sensor is fixed on the contact plate.

[0006] The beneficial effects of the present invention are as follows: in terms of the overall technical solution, the existing electric retractable moxa stick is changed to a manual one, which avoids skin burns caused by the inability to remove the moxa cup in time due to sensor failure in certain situations, or the untimely control of the retraction of the moxa stick, further reducing the safety risk.

[0007] In terms of specific structure, the filter device adopts a modular structure and is embedded in the tank body in a detachable manner, which makes replacement quick and easy. The overall modular structure is compact and easy to carry, so moxibustion can be performed anytime and anywhere. The switch is turned on and off by long pressing the power button, the negative pressure intensity is adjusted by the gear key, and the moxibustion time is set by the mode button so that it falls off regularly, which is simple to operate. A temperature sensor is set on the tank assembly to monitor the temperature of the moxa stick in real time to avoid burns to the skin; the distance between the front end of the moxa stick and the skin is manually and quickly adjusted by rotating the assembly to avoid the tank body being unable to be removed in the event of an accident, which may aggravate the burns and make it safer to use. By coordinating with the negative pressure tank body, the skin is adsorbed into the tank body during moxibustion, and moxibustion is more effectively implemented without falling off the tank body. The streamlined shape makes the appearance more beautiful and easier to hold.

[0008] The MCU's precise control of each module enables precise adjustment of the moxibustion device's temperature, pressure, and other parameters, improving moxibustion safety. The use of a TYPE-C interface module and a power detection module facilitates quick charging, enhancing the device's versatility and compatibility. Equipped with an alarm module and a solenoid pressure relief valve, when the temperature sensor detects an abnormal overtemperature condition, it promptly issues an alarm and rapidly relieves pressure by controlling the solenoid pressure relief valve, ensuring user safety. Powered by a rechargeable lithium battery, it's free from electrical constraints, making it more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following combination Figures 1 to 15 , the specific contents of the utility model are described in detail through specific embodiments. Example 1

[0025] The moxibustion instrument includes a rotating assembly, a shell assembly, and a tank assembly. The rotating assembly can be rotated and telescopically fitted in the shell assembly, and the distance between the front end of the moxa stick 1 and the front end of the tank assembly can be adjusted by the rotating assembly. Among them, the rotating assembly includes a rotating body 22, a stud 23 with a pin 24 fixed at the bottom and driven by the rotating body 22; the rotating body 22 is a hollow structure, including a disc-shaped main structure for holding, a stud fitting part 223 provided with an annular groove 2231 provided on the main structure, and a clamp 25 limited on the annular groove 2231; the side of the threaded part of the stud 23 is provided with a strip groove 232 along the length direction, the bottom of the threaded part is provided with a light rod 231 with an inward diameter, and the inner wall of the stud fitting part 223 is provided with an internal thread that is screwed with the stud 23.

[0026] The disc-shaped main structure of the rotating body 22 is provided with several fixing parts 221 along the circumferential direction, and the fixing parts 221 are provided with through holes 222; the cover body 21 is fixed on the rotating body 22, and the cover body 21 includes several positioning parts 211 that cooperate with the fixing parts 221; the rotating body 22 is engaged with the positioning parts 211 through screws passing through the through holes 222.

[0027] The housing assembly includes a middle housing 32 with a stud retainer 326 internally positioned therein, a shroud 325 positioned over the stud retainer 326, an exhaust assembly 3254 positioned on one side of the shroud 325, a drive motor 324, a PCB 34, a battery 323 positioned within the middle housing 32, and a tank connection end 329 positioned at the bottom of the middle housing 32. The inner wall of the stud retainer 326 is provided with an inner protrusion 3261 that mates with the strip groove 232. A charging port 321 is provided on the outer wall of the middle housing 32, into which the USB port of the charging module on the PCB 34 is embedded.

[0028] The exhaust component 3254 cooperates with the socket 3271 on one side of the guide cavity 327 through the sliding groove structure on its side, so that the guide cover 325 is inserted and installed in the guide cavity 327 from the bottom of the middle shell 32, realizing the limitation of the top of the guide cover 325, and the bottom of the guide cover 325 elastically rests on the annular boss at the bottom of the middle shell 32 through the limiting card 3253 to realize the limitation of the bottom of the guide cover 325. After the guide cavity 327 is inserted and fixed, the inlet end of the exhaust component 3254 at its end corresponds to the outlet end of the guide cover 325, and the exhaust port 3251 of the exhaust component 3254 corresponds to the smoke exhaust port 322 on the middle shell 32; after the top and bottom of the guide cover 325 are limited respectively, the guide cover 325 is fastened to the middle shell 32 by a number of bolts. By installing a filter assembly (not shown) at the junction of the deflector 325 and the exhaust assembly 3254, or within the exhaust assembly 3254, or at the exhaust port 3251, smoke and dust from the combustion of the moxa stick 1 can be effectively filtered, thereby purifying the air. The air inlet 3252 of the deflector 325 communicates with the air inlet duct 452 through the inner cavity of the inner tank 42, thereby forming an air flow path and ensuring oxygen supply during the combustion of the moxa stick 1. Several through-holes (not shown) are provided on the inner wall of the inner tank 42 on the inside of the air inlet duct 452 to slow the pressure release rate of the tank.

[0029] In order to make the shell assembly more beautiful and facilitate the assembly of other components, the shell assembly can be divided into three parts for manufacturing. For example, the upper shell 31 and the lower shell 33 are fixed at the upper and lower ends of the middle shell 32 respectively. The upper shell 31 includes a main body with a hollow portion 311 and a circular groove 313 at the upper end, and a male buckle 312 arranged on the side. The inner side of the middle shell 32 is provided with a female buckle 328 corresponding to the position of the male buckle 312. The upper shell 31 is fixed to the female buckle 328 of the middle shell 32 through the male buckle 312. The rotating assembly can be rotatably fitted in the circular groove 313. The lower shell 33 adopts a hollow structure that cooperates with the tank connection end 329, and is respectively provided with screw holes 331 around it. The lower shell 33 is fixed to the bottom of the middle shell 32 by bolts passing through the bottom of the middle shell 32.

[0030] The tank assembly includes an embedded portion 43 that fits on the tank connection end 329, a partition 44 fixed to the embedded portion 43, a tank sidewall 45 with an opening 451 at the bottom, an inner tank body 42 disposed within the tank sidewall 45, and a hollow baffle 41 retained within the inner tank body 42. The inner tank body 42 and the tank sidewall 45 are connected via an air inlet 452 and a temperature measurement cavity 453. Several retaining grooves 3293 are circumferentially provided on the inner side of the tank connection end 329. The opening 451 can adopt a wavy structure to allow the tank assembly to better fit the human body. The embedded portion 43 is circumferentially provided with an expansion protrusion 431 for positioning and engaging, and several retaining protrusions 432 that engage with the retaining grooves 3293.

[0031] The partition 44 is circumferentially provided with several positioning holes 441 that mate with the positioning protrusions 3291. A temperature sensor is mounted on the lower contact 433, which extends through the partition 44 and is positioned therein. The bottom of the lower contact 433 is inserted into the embedded portion 43. An upper contact 3292 is located inside the tank connection end 329, mates with the lower contact 433, and is electrically connected to the PCB 34. The mounting slot for the lower contact 433 of the tank assembly extends downward and connects to the temperature measurement cavity 453.

[0032] During use, the can assembly is rotated to disengage the limiting protrusion 432 from the slot 3293, and then the can assembly is removed to fix the moxa stick 1 on the pin 24. At this time, the upper contact 3292 and the lower contact 433 are disengaged, and there is no response when the control button (not marked in the figure) on the housing 32 is accidentally touched.

[0033] After lighting the moxa stick 1, the tank assembly is rotated in the opposite direction to clamp it to the bottom of the middle shell 32. The upper contact 3292 and the lower contact 433 are connected, the temperature sensor on the lower contact 433 is started, and the trigger control button can start the moxibustion instrument normally.

[0034] After the moxibustion device is activated, the moxa stick 1 is first adjusted to the farthest point from the skin by manually controlling the rotating assembly, and then the moxibustion device is adsorbed onto the desired acupuncture point. When the cover 21 and the rotating body 22 are rotated, the stud mating portion 223 is limited by the clamp 25 to the inner wall of the hollow portion 311 of the upper shell 31. When the rotating body 22 rotates, the internal thread of the stud 23 is driven to expand and contract, thereby driving the moxa stick 1 toward or away from the moxibustion acupuncture point. When the stud 23 contracts toward the rotating assembly, the end of the stud 23 extends into the cavity between the cover 21 and the rotating body 22 to quickly adjust the moxibustion temperature. The temperature sensor located on the lower contact 433 monitors the internal cavity temperature of the inner tank 42 in real time. When the temperature is too high, an alarm is triggered or the drive motor 324 is turned off, and the tank assembly falls off from the skin to prevent burns. Example 2

[0035] like Figure 6As shown, this embodiment is a circuit principle block diagram of the PCB circuit board 34 in Example 1. The control system for the moxibustion instrument includes an MCU (preferably STM32G030), a charging module, a battery, and an alarm module (preferably a buzzer and a light alarm). Among them, the MCU is electrically connected to the charging module, and the charging module is electrically connected to the TYPE-C interface module and the battery respectively. The signal output end of the MCU is electrically connected to the exhaust component, the negative pressure pump, the alarm module, and the electromagnetic pressure relief valve respectively. The signal input end of the MCU is electrically connected to the temperature sensor and the pressure sensor (preferably XGZP6859D) respectively. The pressure sensor is fixed on the contact plate (upper contact 3292).

[0036] During use, the tank assembly is installed at the bottom of the housing assembly. Lower contact 433 then contacts upper contact 3292, and the pressure sensor sends a signal to the MCU indicating the tank assembly is in place. Simultaneously, the temperature sensor activates, monitoring the temperature inside the tank assembly in real time. Once the MCU detects that the temperature exceeds a set threshold, it sends a control signal to the electromagnetic pressure relief valve and alarm module (buzzer), simultaneously stopping the negative pressure pump. The moxibustion device then automatically detaches from the skin, preventing burns. When the temperature inside the tank assembly falls below the threshold, the system is activated via the power-on / off module. The MCU activates the negative pressure pump (drive motor 324) and exhaust assembly 3254, beginning moxibustion treatment.
