[0049] 4. Mugwort cake. Detailed Implementation

[0050] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0051] First, combine Figures 1-4 The multi-can combination moxibustion cupping 3 according to the embodiments of the present utility model is used for health preservation and has a wide range of applications.

[0052] like Figures 1-4 As shown, the multi-can combination moxibustion cupping 3 of this utility model embodiment includes: a main unit 1 and multiple moxibustion cups 3.

[0053] Specifically, such as Figures 1-4 As shown, in this embodiment, the host 1 is connected to multiple moxibustion cupping 3s via a wiring harness 2, controlling the multiple moxibustion cupping 3s to start or stop. It can realize simultaneous cupping and moxibustion on multiple parts according to usage needs, increasing the range of cupping and moxibustion, and the operation is simple and fast.

[0054] In this embodiment, as Figure 1 As shown, in this embodiment, the host 1 includes: a host housing 11, the surface of which is provided with a plurality of first interfaces 12, which are respectively connected to a plurality of moxibustion cupping jars 3 via wiring harness 2; a negative pressure generating module, which is disposed inside the host housing 11 and connected to the first interfaces 12, the negative pressure generating module drives the moxibustion cupping jars 3 to generate negative pressure, and releases pressure after the cupping is completed; and a power control module, which is disposed inside the host housing 11 and connected to the negative pressure generating module and the plurality of first interfaces 12, the power control module supplies power to the negative pressure generating module, supplies power to the plurality of moxibustion cupping jars 3 through the plurality of first interfaces 12 and wiring harness 2, and outputs control signals.

[0055] In this embodiment, the wire harness 2 is made of a negative pressure tube and a multi-core wire. The negative pressure tube delivers air, and the multi-core wire delivers power and control signals. The two ends of the wire harness 2 are provided with quick-connect connectors 21, which are respectively connected to the first interface 12 and the moxibustion cupping 3. In this embodiment, one wire harness 2 connects two first interfaces 12 and two moxibustion cupping 3, thereby improving the connection efficiency.

[0056] Specifically, such as Figure 1 and Figure 4 As shown, in this embodiment, the negative pressure generating module includes: a negative pressure pump 131, multiple on / off solenoid valves 133, and a pressure relief solenoid valve 134. The negative pressure pump 131, multiple on / off solenoid valves 133, and pressure relief solenoid valve 134 are all housed within the main unit casing 11 and are all connected to the power control module. The power control module controls the start and stop of the negative pressure pump 131, multiple on / off solenoid valves 133, and pressure relief solenoid valve 134. One end of each of the multiple on / off solenoid valves 133 is connected to the negative pressure pump 131 via a main pipeline 132, meaning the output end of the negative pressure pump 131 is connected to the main pipeline 132, and the main pipeline 132 is connected to the multiple on / off solenoid valves 134. One end of the solenoid valve 133 is connected to the main pipe 132, and the other end of the multiple on / off solenoid valves 133 is connected to multiple first interfaces 12 respectively. The number of on / off solenoid valves 133 corresponds one-to-one with the number of moxibustion cupping 3. The on / off solenoid valves 133 control the on / off of the moxibustion cupping 3 and the negative pressure pump 131. The on / off solenoid valves 133 realize the electrical control of the connection between the moxibustion cupping 3 and the negative pressure pump 131, which facilitates the simultaneous start and stop of multiple moxibustion cupping 3. One end of the pressure relief solenoid valve 134 is connected to the main pipe 132, and the other end is connected to the outside of the main unit housing 11. The pressure relief solenoid valve 134 is used to relieve pressure on multiple moxibustion cupping 3.

[0057] Under normal conditions, multiple on / off solenoid valves 133 and pressure relief solenoid valve 134 are closed. During cupping, the user connects the main unit 1 and multiple moxibustion cups 3 using wiring harness 2. The power control module controls the opening of multiple on / off solenoid valves 133, connecting the negative pressure pump 131 and multiple moxibustion cups 3, and turning on the negative pressure pump 131. The negative pressure pump 131 evacuates the negative pressure chamber 32 of the moxibustion cups 3 through wiring harness 2, so that negative pressure is generated in the negative pressure chamber 32. After reaching the set value, the negative pressure pump 131 is turned off to perform cupping. After the cupping is completed, the pressure relief solenoid valve 134 is opened to release the pressure of multiple moxibustion cups 3, making it convenient for the moxibustion cups 3 to be removed from the body.

[0058] Furthermore, such as Figures 1-4As shown, in this embodiment, the negative pressure generating module further includes a negative pressure sensor 135. The negative pressure sensor 135 is disposed inside the main unit housing 11. The negative pressure sensor 135 is connected to the power control module and the main pipeline 132 to detect the negative pressure of the moxibustion cupping 3 in real time. The negative pressure sensor 135 is disposed at the main pipeline 132 to facilitate the detection of the negative pressure of the main pipeline 132 and to feed the signal back to the power control module, so as to avoid the moxibustion cupping 3 from falling off due to insufficient pressure or excessive pressure, which would cause pain when it adheres to the skin.

[0059] Specifically, such as Figures 1-4 As shown, in this embodiment, the power control module includes: a battery 141, a circuit control board 142, and a control button 143. The circuit control board 142 is an existing type. The battery 141 and the circuit control board 142 are disposed inside the main unit housing 11, and the control button 143 is disposed on the outer surface of the main unit housing 11. The battery 141 is connected to the circuit control board 142, multiple first interfaces 12, and a negative pressure generating module, providing the electrical energy required for the circuit control board 142, the negative pressure generating module, and multiple moxibustion cupping devices 3 to operate. The circuit control board 142 is connected to the negative pressure generating module and multiple first interfaces 12 for sending control signals. The control button 143 is connected to the circuit control board 142, and the user outputs control commands through the control button 143 to control the start / stop and gear switching of the main unit 1. In this embodiment, a display module 144 is also included. The display module 144 is connected to the battery 141 and the circuit control board 142 for intuitively displaying the current working status. The display module 144 can be a display screen.

[0060] Specifically, such as Figures 1-4 As shown, in this embodiment, the moxibustion cupping 3 includes: a cup body, with a second interface 31 at the top of the cup body, the second interface 31 being connected to the host 1 via a wire harness 2, and a negative pressure chamber 32 formed at the bottom opening of the cup body, the negative pressure chamber 32 being connected to the second interface 31; and a moxibustion module, which is disposed inside the cup body and connected to the second interface 31, the moxibustion module heating the moxa cake 4 to release moxa heat. In this embodiment, the moxibustion cupping 3 integrates the dual effects of cupping and moxibustion, achieving synergistic effects. It stimulates acupoints on the body surface through negative pressure suction, promoting local blood circulation, while the heat from the moxa cake 4 penetrates to deep tissues, realizing the synergistic effect of cupping and moxibustion and enhancing the user experience.

[0061] Furthermore, such as Figures 1-4 As shown, in this embodiment, the can body includes: a top cover 331, a fixing body 332, and an outer cover 333; the top cover 331, the fixing body 332, and the outer cover 333 are fixed from top to bottom; a second interface 31 is provided on the top cover 331; the outer cover 333 surrounds the bottom of the fixing body 332, and a negative pressure cavity 32 is formed between the bottom of the fixing body 332 and the outer cover 333; the moxibustion module is fixed on the fixing body 332 and housed in the outer cover 333.

[0062] Specifically, such as Figures 1-4 As shown, in this embodiment, the moxibustion module includes: a first circuit board 34, a flexible connector 35, a fixing frame 36, and a heating mechanism; the first circuit board 34 is fixed on the fixing body 332 and connected to the second interface 31. The first circuit board 34 is an existing type used for conversion to realize the transmission of electrical energy and signals between the heating mechanism and the second interface 31; the flexible connector 35 is cylindrical, with its top fixed on the fixing body 332, and its interior is hollow; in this embodiment, the flexible connector 35 is sealed to the fixing body 332 through a sealing gasket 351 to ensure the reliability of the negative pressure; in this embodiment, the flexible connector 35 is made of silicone, and its longitudinal cross-section is wavy. During moxibustion, the user's skin is in close contact with the moxa cake 4 to achieve the therapeutic effect of moxibustion. At this time, under the action of negative pressure, the user's skin will be gently attracted upward, forming a natural protrusion. The greater the intensity of the negative pressure, the greater the degree of skin protrusion. To accommodate changes in skin ridges and ensure optimal comfort throughout the moxibustion process, a flexible silicone connector 35 allows for flexible contact between the user and the moxa cake 4, enhancing user comfort. The wavy, layered design of the flexible connector 35 allows it to expand and contract, accommodating varying ridge heights. It flexibly adjusts its shape to maintain stable and comfortable contact between the user's skin and the moxa cake 4 regardless of the degree of skin ridge, further improving the moxibustion effect and user satisfaction. A fixing frame 36 is attached to the bottom of the flexible connector 35, securing the heating mechanism and the moxa cake 4. The heating mechanism is connected to the first circuit board 34 and heats the moxa cake 4 to release heat. In this embodiment, the fixing frame 36 is equipped with a magnetic attachment, and the moxa cake 4 contains one or more iron pieces or pillars that are magnetically attached to the fixing frame 36, allowing for quick and convenient installation and replacement.

[0063] Furthermore, such as Figures 1-4 As shown, in this embodiment, the heating mechanism includes: a mounting bracket 371, a heating element 372, a temperature probe 373, and a second circuit board 374. The second circuit board 374 is an existing type. The mounting bracket 371 is fixed to the bottom of the fixing bracket 36. The heating element 372 and the temperature probe 373 are mounted on the bottom of the fixing bracket 36 via the mounting bracket 371. The second circuit board 374 is fixed to the top of the fixing bracket 36 and is connected to the first circuit board 34. The temperature probe 373 and the heating element 372 are both connected to the second circuit board 374. The heating element 372 heats the moxa cake 4. The heating element 372 is a ceramic heating element. The temperature probe 373 is connected to the heating element 372 to detect the temperature of the heating element 372 and maintain the comfort of the moxa cake 4 in contact with the user's skin.

[0064] Furthermore, such as Figures 1-4 As shown, in this embodiment, the second circuit board 374 is connected to a spring-loaded touch button 375, which passes through the heating mechanism and the moxa cake 4. Specifically, the heating mechanism, the moxa cake 4, and the fixing frame 36 are all annular, with holes for placing the spring-loaded touch button 375. The spring-loaded touch button 375 detects the contact state between the moxibustion module and the human skin. Skin detection is achieved through the spring-loaded touch button 375. When the cupping jar is not in contact with the human skin, the moxibustion cupping 3 does not work, avoiding accidental activation and reducing safety hazards.
