Description

Technical Field

[0001] This invention relates to the field of physiotherapy equipment technology, specifically to an intelligent multifunctional cupping device. Background Technology

[0002] Cupping therapy is a traditional Chinese medicine external treatment method that uses negative pressure created inside a cup to adhere to the skin, thereby promoting blood circulation, relieving swelling and pain, and improving circulation. Traditional cupping procedures often use fire cups or vacuum guns to create negative pressure, and the operation relies on manual experience, making it difficult to precisely control the pressure and temperature inside the cup.

[0003] With the development of electronic technology, some smart cupping devices have appeared on the market. For example, existing technologies place pressure and temperature sensors at the bottom of the cup and connect a vacuum pump and solenoid valve through a controller to achieve automatic pressure regulation inside the cup. Some solutions also communicate with a mobile app via Bluetooth, allowing the mobile terminal to send control signals, but most still have some shortcomings: Firstly, most existing smart cupping devices have an integrated structure, with components such as sensors and suction tubes fixed inside the device. When it is necessary to replace the device with a different size or function, the entire device, including the sensors and control components, must be replaced, resulting in high operating costs and poor compatibility between different devices.

[0004] Secondly, the connection between the cupping device and the main unit in existing cupping devices mostly uses threaded connections or simple plug-in structures. Replacing the cupping device is cumbersome and it is difficult to guarantee the airtightness after replacement. If the connection is not properly sealed, it will lead to negative pressure leakage inside the cupping device, directly affecting the cupping effect and the safety of the treatment.

[0005] Third, the sealing structure of existing intelligent cupping devices is mostly a simple O-ring seal. In usage scenarios where the cups are frequently inserted and removed, the sealing ring is prone to displacement, twisting or wear, leading to seal failure and affecting the service life and reliability of the device. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent multifunctional cupping device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A smart multifunctional cupping device includes a main unit and a replaceable cupping body: the main unit includes a top chamber and a docking seat disposed below the top chamber, the replaceable cupping body includes a cupping body and a docking interface disposed on the top of the cupping body, the docking interface and the docking seat are both conical structures that are narrow at the top and wide at the bottom; the docking interface and the docking seat are inserted into each other and the outer conical surface of the docking interface fits against the inner conical surface of the docking seat. The bottom of the top compartment is equipped with a temperature sensor, a pressure sensor, and an exhaust pipe with an internal solenoid valve. The temperature sensor, pressure sensor, and exhaust pipe all face the docking seat and are not isolated from the internal space of the replaceable tank. The top of the top compartment is equipped with an exhaust port that is connected to the exhaust pipe. The upper surface of the top compartment is equipped with a touch screen, and the interior of the top compartment is equipped with a controller. The controller is electrically connected to the temperature sensor, pressure sensor, solenoid valve and touch screen respectively, and is used to acquire the temperature signal and pressure signal inside the tank, and to control the opening and closing of the exhaust pipe through the solenoid valve to adjust the pressure inside the tank.

[0008] Furthermore, the host computer is also equipped with a Bluetooth module, which is electrically connected to the controller for wireless communication with external mobile terminals.

[0009] Furthermore, a step is provided between the bottom of the outer conical surface of the docking interface and the outer edge of the top of the tank body, and a lower permanent magnet ring is fixedly connected in the step; the lower port of the docking seat is a thick-walled structure and is fixedly connected with an upper permanent magnet ring, the lower permanent magnet ring and the upper permanent magnet ring are positioned correspondingly, and the two are locked together by magnetic attraction to assist in locking the docking interface and the docking seat.

[0010] Furthermore, a sealing ring is connected to the conical inner wall of the mating seat, and the sealing ring is used to seal the mating gap after the outer conical surface of the mating interface and the inner conical surface of the mating seat are fitted together.

[0011] Furthermore, the conical inner wall of the docking seat is provided with a sealing ring groove, and the sealing ring is engaged in the sealing ring groove.

[0012] Furthermore, the longitudinal section of the sealing ring groove is dovetail-shaped, including a wedge-shaped slope on the outer side and a bottom groove on the inner side. The opening of the wedge-shaped slope opens radially inward, and the axial width of the bottom groove is greater than the axial width at the bottom of the wedge-shaped slope. The outer periphery of the sealing ring is provided with an annular groove extending radially inward. The sealing ring has convex rings protruding upward and downward at the outer port of the annular groove. The upper and lower convex rings pass through the wedge-shaped slope and are inserted into the bottom groove. The outer wall of the convex ring abuts against the upper and lower side walls of the bottom groove, respectively, to achieve axial bidirectional limiting.

[0013] Furthermore, the radial inner bottom wall of the annular groove is provided with relief cavities distributed circumferentially and bulging upward and downward respectively; when the sealing ring is subjected to radial extrusion force, the relief cavities provide relief space for the extrusion deformation of the sealing ring body by radial narrowing.

[0014] Furthermore, the can body is made of transparent material, and its outer peripheral wall is provided with anti-slip protrusions distributed circumferentially. The anti-slip protrusions are used to provide grip friction when changing the can body.

[0015] Furthermore, a miniature air extraction pump is installed inside the top compartment, the miniature air extraction pump is connected to the air extraction pipe, and the solenoid valve is located between the miniature air extraction pump and the air extraction pipe.

[0016] Furthermore, the top compartment is equipped with a battery, and the top of the top compartment is equipped with a charging port that is electrically connected to the battery.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a separate design of the main unit and the replaceable tank, along with a conical interface (narrower at the top and wider at the bottom) and a docking seat for insertion. Leveraging the self-centering and self-sealing properties of the conical surface, it achieves rapid replacement, automatic alignment, and reliable sealing of different tanks. This solves the problems of high operating costs, poor tank versatility, and difficulty in guaranteeing airtightness after replacement inherent in existing integrated tank designs. By centrally positioning the temperature sensor, pressure sensor, and extraction pipe at the bottom of the top compartment facing the docking seat, without isolation from the tank's internal space, the sensors can directly perceive the tank's internal conditions. This solves the problem of delayed response caused by sensor isolation in existing technologies, improving the accuracy and response speed of pressure regulation and temperature monitoring. Furthermore, the magnetic attraction between the upper and lower permanent magnet rings provides auxiliary locking force on top of the conical insertion, preventing the replaceable tank from loosening due to vibration or accidental contact during use, thus improving safety and reliability.

[0018] 2. This invention achieves axial bidirectional limiting of the sealing ring through the dovetail-shaped longitudinal section structure of the sealing ring groove (including a wedge-shaped slope and a bottom groove) and the snap-fit ​​between the convex ring on the sealing ring and the bottom groove. This solves the problem of the sealing ring easily shifting, twisting, or falling off during frequent insertion and removal from the tank. The clearance cavity set in the bottom wall of the annular groove on the sealing ring provides clearance space for the compression deformation of the sealing ring body when the sealing ring is subjected to radial compression, reducing insertion and removal resistance. At the same time, it ensures the elastic recovery ability of the sealing ring after long-term use and extends the service life of the sealing ring.

[0019] 3. This invention uses a dual interaction method of touch screen and Bluetooth module, allowing users to set parameters and view status directly on the device, as well as remotely control and manage data through an external mobile terminal. This solves the problem of the single interaction method in the prior art, which cannot meet the needs of different usage scenarios, and improves the intelligence level of the device and the user experience.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1 Please see Figures 1-9 A smart multi-functional cupping device includes a main unit 2 and a replaceable cupping body 1.

[0024] The main unit 2 includes a top compartment 201 and a docking seat 207 located below the top compartment 201. The top compartment 201 houses a controller and a battery. The upper surface of the top compartment 201 is equipped with a touch screen. The top of the top compartment 201 has an air outlet 204 connected to the air extraction pipe 203 and a charging port 206 for charging the battery.

[0025] The replaceable tank 1 includes a tank body 101 and a docking interface 102 disposed on the top of the tank body 101. The docking interface 102 and the docking seat 207 are both conical structures that are narrow at the top and wide at the bottom. The docking interface 102 and the docking seat 207 are inserted and fitted together, and the outer conical surface of the docking interface 102 fits against the inner conical surface of the docking seat 207.

[0026] The bottom of the top compartment 201 is equipped with a temperature sensor 202, a pressure sensor 216, and an extraction pipe 203 with an internal solenoid valve. The temperature sensor 202, pressure sensor 216, and extraction pipe 203 all face the docking seat 207 and are not isolated from the internal space of the replaceable tank 1. A miniature extraction pump is installed inside the top compartment 201, connected to the extraction pipe 203. The solenoid valve is located between the miniature extraction pump and the extraction pipe 203.

[0027] The controller is electrically connected to the temperature sensor 202, the pressure sensor 216, the solenoid valve, and the touch screen to acquire the temperature and pressure signals inside the tank, and to control the opening and closing of the suction pipe 203 through the solenoid valve to regulate the pressure inside the tank.

[0028] The host unit 2 is also equipped with a Bluetooth module, which is electrically connected to the controller and is used for wireless communication with external mobile terminals.

[0029] A step 103 is provided between the bottom of the outer conical surface of the interface 102 and the outer edge of the top of the tank body 101, and a lower permanent magnet ring 104 is fixedly connected inside the step 103. The lower port of the docking seat 207 has a thick-walled structure and is fixedly connected to an upper permanent magnet ring 215. The lower permanent magnet ring 104 and the upper permanent magnet ring 215 are positioned correspondingly, and the two are locked together by magnetic attraction to facilitate the insertion and mating of the interface 102 and the docking seat 207.

[0030] A sealing ring groove 208 is provided on the conical inner wall of the mating seat 207, and a sealing ring 211 is snapped into the sealing ring groove 208. The sealing ring 211 is used to seal the mating gap after the outer conical surface of the mating interface 102 and the inner conical surface of the mating seat 207 are in contact.

[0031] The longitudinal section of the sealing ring groove 208 is dovetail-shaped, including a wedge-shaped slope 209 on the outer side and a bottom groove 210 on the inner side. The opening of the wedge-shaped slope 209 opens radially inward, and the axial width of the bottom groove 210 is greater than the axial width at the bottom of the wedge-shaped slope 209.

[0032] The outer periphery of the sealing ring 211 has an annular groove 213 extending radially inward. At the outer port of the annular groove 213, the sealing ring 211 has protruding rings 214 protruding upward and downward, respectively. The upper and lower protruding rings 214 pass through the wedge-shaped slope 209 and are engaged in the bottom groove 210. The outer walls of the protruding rings 214 abut against the upper and lower side walls of the bottom groove 210, respectively, to achieve axial bidirectional limiting.

[0033] The annular groove 213 has circumferentially distributed relief cavities 212 that bulge upwards and downwards respectively on its radial inner bottom wall. When the sealing ring 211 is subjected to radial extrusion force, the relief cavities 212 provide relief space for the extrusion deformation of the sealing ring body by radially narrowing.

[0034] The can body 101 is made of transparent material, and its outer peripheral wall has anti-slip protrusions distributed in a circumferential direction. The anti-slip protrusions are used to provide grip friction when changing the can body.

[0035] Working principle:

[0036] The user selects a suitable replaceable canister 1 according to treatment needs, aligns the interface 102 on the top of the canister 101 with the docking seat 207 of the main unit 2, and pushes it upwards axially. Under the guidance of the conical surface, the outer conical surface of the interface 102 gradually fits into the inner conical surface of the docking seat 207, achieving the insertion and engagement of the interface 102 and the docking seat 207. At the same time, the lower permanent magnet ring 104 in the step 103 and the upper permanent magnet ring 215 at the lower port of the docking seat 207 attract each other under the action of magnetic attraction, assisting in locking the insertion and engagement and preventing the replaceable canister 1 from accidentally falling off during use.

[0037] When the interface 102 is inserted into the docking seat 207, the sealing ring 211 elastically abuts against the outer conical surface of the interface 102, eliminating the clearance between the conical surfaces and achieving an airtight seal. Since the temperature sensor 202, pressure sensor 216, and suction pipe 203 all face the docking seat 207 and are not isolated from the internal space of the replaceable tank 1, each sensor can directly sense the temperature and pressure of the air inside the tank, and the suction pipe 203 can directly perform suction or venting operations inside the tank.

[0038] Users can set target pressure and temperature values ​​via the touchscreen on the top surface of the top chamber 201, or connect to an external mobile terminal via Bluetooth to set parameters. After receiving the settings, the controller activates a miniature suction pump to evacuate air from the replaceable canister 1 through the suction pipe 203. Temperature sensor 202 and pressure sensor 216 collect real-time temperature and pressure signals from inside the canister and transmit them to the controller. When the pressure inside the canister reaches the set value, the controller closes the solenoid valve, stopping the suction and maintaining the required negative pressure inside the canister. During cupping, if the pressure inside the canister deviates from the set value due to leakage or other reasons, the controller controls the opening and closing of the solenoid valve based on the feedback signal from pressure sensor 216 to dynamically adjust the pressure inside the canister. Simultaneously, the controller monitors the temperature inside the canister based on the signal from temperature sensor 202 to ensure the temperature remains within a safe range.

[0039] Users can view the pressure and temperature values ​​inside the tank and the equipment's operating status in real time via the touch screen, and can also transmit data to an external mobile terminal for display and recording via Bluetooth module.

[0040] This embodiment uses a separate setup of the main unit 2 and the replaceable tank 1, allowing users to replace the tank with different specifications or functions according to the treatment site and the condition, without having to replace the entire main unit containing sensors and control components. This reduces the cost of use and improves the versatility and flexibility of the equipment.

[0041] The conical interface 102, which is narrower at the top and wider at the bottom, is inserted into the docking seat 207. The self-centering property of the conical surface is used to achieve automatic alignment between the interface and the docking seat, ensuring the positioning accuracy after the tank is replaced. At the same time, the self-sealing property of the conical surface, combined with the elastic contact of the sealing ring 211, ensures the airtightness after the tank is replaced.

[0042] By centrally arranging the temperature sensor 202, pressure sensor 216, and suction pipe 203 at the bottom of the top chamber 201 and facing the docking seat 207, and without isolating them from the internal space of the tank, the sensors can directly and in real time perceive the working conditions inside the tank, avoiding response delays caused by isolation settings, and improving the accuracy and response speed of pressure regulation and temperature monitoring.

[0043] The magnetic attraction between the upper permanent magnet ring 215 and the lower permanent magnet ring 104 provides an auxiliary locking force on the basis of the conical insertion, preventing the replaceable tank 1 from loosening due to vibration or accidental contact during use, thus improving the safety and reliability of use.

[0044] With dual interaction via touchscreen and Bluetooth module, users can set parameters and view status directly on the device, or remotely control and manage data via external mobile terminal, meeting the operational needs of different usage scenarios.

[0045] Example 2 Please see Figures 1-9 A smart multifunctional cupping device, which differs from Embodiment 1 in that the main unit 2 in this embodiment does not have a built-in micro air pump, but instead connects to an external air pumping device through the air outlet 204 to achieve the air pumping function.

[0046] Specifically, the top of the top compartment 201 is provided with an air outlet 204 that communicates with the suction pipe 203. The air outlet 204 is configured as a connection port adapted to the pipeline interface of an external suction device. In use, an external suction device (such as a medical vacuum pump or a manual suction cylinder) is connected to the air outlet 204 through a pipeline. After the external suction device is started, air is evacuated from the inside of the replaceable tank 1 through the suction pipe 203. A solenoid valve is provided on the suction pipe 203 to cut off the suction pipeline when a set pressure value is reached, maintaining negative pressure inside the tank.

[0047] In this embodiment, the layout and connection relationship of the temperature sensor 202, pressure sensor 216, and suction pipe 203, the conical insertion and mating structure of the interface 102 and the docking seat 207, the sealing ring 211 and its snap-fit ​​structure, the magnetic attraction-assisted locking structure of the upper permanent magnet ring 215 and the lower permanent magnet ring 104, as well as the configuration and functions of the touch screen, controller, and Bluetooth module are all the same as in embodiment 1, and will not be repeated here.

[0048] The working principle of this embodiment is as follows:

[0049] The user connects the external air extraction device to the air outlet 204 via a pipe, and inserts the interface 102 of the selected replaceable tank 1 into the docking seat 207 of the main unit 2 to complete the installation and sealing of the tank. After setting the target pressure value via the touch screen or external mobile terminal, the user starts the external air extraction device, which extracts air from the inside of the replaceable tank 1 through the air outlet 204 and the extraction pipe 203. The pressure sensor 216 monitors the pressure inside the tank in real time and transmits the signal to the controller. When the pressure inside the tank reaches the set value, the controller controls the solenoid valve to close, cutting off the extraction pipe, and the external air extraction device stops working, maintaining the required negative pressure inside the tank.

[0050] During the cupping process, if the pressure inside the cup deviates from the set value, the controller controls the solenoid valve to open or close based on the feedback signal from the pressure sensor 216, and works with external air extraction equipment to perform supplementary extraction or air release operations, thereby achieving dynamic adjustment of the pressure inside the cup.

[0051] Compared to Embodiment 1, this embodiment simplifies the internal structure of the main unit 2 by eliminating the built-in micro vacuum pump, reducing the weight of the device and lowering manufacturing costs. Simultaneously, the air outlet 204 can be adapted to different types of external vacuum devices, allowing users to choose different vacuuming methods such as medical vacuum pumps or manual vacuum cylinders according to actual conditions, thus improving the flexibility of the device.

[0052] Furthermore, since the layout and connection of the temperature sensor 202 and the pressure sensor 216 in this embodiment, as well as the core components such as the conical insertion sealing structure and the magnetic assisted locking structure, are completely consistent with those in Embodiment 1, it also possesses the beneficial effects of rapid tank replacement, accurate positioning, reliable sealing, and precise sensing described in Embodiment 1.
