Description

Technical Field

[0001] This utility model relates to moxibustion, and in particular to a portable smokeless moxibustion device, belonging to the technical field of moxibustion equipment. Background Technology

[0002] As a physiotherapy device, moxibustion devices are commonly used in existing medical and health care settings. To overcome the environmental discomfort caused by the smoke produced during moxibustion, the industry has developed smokeless moxibustion devices and solutions. Several such solutions are disclosed in Chinese patent applications, such as CN118141685A (smokeless moxibustion device), CN114588014A (smokeless moxibustion device), CN119139132A (intelligent smokeless moxibustion device and its operating method), and CN118662353A (smokeless pressure moxibustion device). To achieve a smokeless effect, these devices generally have a large main unit, resulting in poor mobility and portability. CN222788157U discloses a portable smokeless moxibustion massager, which uses filtration to eliminate smoke, but requires filter material and the smoke elimination is incomplete; CN110252077A... A portable smokeless moxibustion device is disclosed, which employs a handheld, handle-equipped device for converting moxa smoke into liquid moxa oil. It also includes an oil filtration system for residual smoke, an activated carbon deodorization system, a water filtration neutralization system, and a water-cooled radiator system. The structure is complex and requires water cooling because the smoke carries a significant amount of heat. Existing smokeless moxibustion devices lose heat along with the smoke, greatly reducing the utilization rate of heat generated during moxibustion. Furthermore, existing moxibustion devices generally suffer from high outer shell temperatures, increasing the risk of burns. Summary of the Invention

[0028] As shown in the accompanying drawings, a portable smoke - eliminating two - process moxibustion device includes a housing and a moxibustion bin. The housing includes an upper shell 1 and a lower shell 2. A upper connecting plate 26 is fixedly connected to the lower part inside the upper shell 1, and a lower connecting plate 14 is arranged below the upper connecting plate. A combustion bin is fixedly connected to the lower connecting plate 14. The combustion bin includes an outer bin 28 and an inner bin 27. The outer bin 28 is fixedly connected to the upper connecting plate, and three horizontal limit columns 39 are fixedly connected to the outer periphery of the inner bin 27. Air outlet holes are formed on the outer wall of the outer bin. The air outlet holes formed on the outer bin are in two layers, with multiple air outlet holes in each layer. In the figure, 40 is the upper layer air outlet and 41 is the lower layer air outlet, and both layers of air outlet holes can discharge air.

[0029] An ignition component is fixedly connected to the flange at the lower port of the combustion bin. The ignition component is composed of an ignition upper insulating plate 11, an ignition wire winding plate 10, and an ignition lower insulating plate 9 stacked from top to bottom. A first ignition wire is wound on the ignition wire winding plate, and both ends of the first ignition wire are connected to the two poles of a power supply; the first ignition wire is the same as the second ignition wire, and the first ignition wire is not shown in the figure. The connection terminals are fixedly connected to the outer edge part (outside the outer bin) of the ignition component. A dust separation net 8 is fixedly arranged below the ignition component; an anti - scald sleeve 7 is fixedly connected below the ignition component. The anti - scald sleeve is located in the middle hole of the lower cover 29. An air outlet hole is formed on the lower cover 29, and the lower cover is fixedly connected to the lower port part of the lower shell;

[0030] The lower smoke guide duct 12 is connected to the inner chamber 28 and is used to guide smoke upwards. The lower end of the lower smoke guide duct has three L-shaped slots 37 corresponding to limiting posts. The limiting posts 39 are engaged in the horizontal sides of the L-shaped slots. The lower smoke guide duct 12 is fixedly connected to the upper smoke guide inner cylinder. Multiple screw holes 38 are machined on the peripheral wall of the lower smoke guide duct, and multiple elongated holes 34 corresponding to the screw holes are opened on the wall of the upper smoke guide inner cylinder. The upper smoke guide inner cylinder and the lower smoke guide duct are fixedly connected by screws passing through the elongated holes. This allows for adjustment of the overall height and avoids interference between components during assembly. An upper cover 32 is fixedly installed at the upper end of the upper smoke guide inner cylinder 13. The upper cover has multiple smoke guide holes 36. An upper smoke guide outer cylinder 15 is fixedly connected to or integrally formed with the upper smoke guide inner cylinder 13. The lower end of the upper smoke guide outer cylinder 15 is fixedly connected to the upper connecting plate 26.

[0031] A smoke-eliminating assembly is fixedly connected to the upper end of the upper smoke-guiding outer cylinder via a smoke-guiding flange. The smoke-eliminating assembly, from bottom to top, consists of an upper smoke-eliminating insulating plate 23, a smoke-eliminating filament winding plate 24, and a lower smoke-eliminating insulating plate 25 stacked together. A second ignition wire 31 is wound on the smoke-eliminating filament winding plate, with its two ends connected to the two poles of a power supply. Each of the upper, lower, and upper smoke-eliminating insulating plates includes an inner ring cavity 22. An outer ring body 16 is fixedly connected to the inner ring cavity via reinforcing ribs. The smoke-eliminating filament winding plate is located within the inner ring cavity 22. The upper smoke-guiding inner cylinder 13 corresponds to the lower end of the inner ring cavity. The upper cover 32 of the upper smoke-guiding inner cylinder has a smoke-guiding hole 36. The smoke-guiding flange and the outer ring... The components 16 are fixedly connected. The upper part of the smoke elimination assembly is a smoke elimination chamber, which includes an inner chamber 21 and an outer chamber 22. The lower end of the inner chamber 21 is connected to the inner annular cavity 22, and the upper end is closed. A fan 18 is fixedly installed on the top of the outer chamber. Four radial air outlet pipes 17 are arranged near the top of the inner chamber. The four radial air outlet pipes are evenly distributed around the circumference of the inner chamber and connect the outside of the outer chamber and the inside of the inner chamber. A U-shaped air outlet baffle 30 is fixedly connected to the outer wall of the outer chamber at the outer end of the air outlet pipe. The bottom surface of the U-shaped air outlet baffle is radially opposite to the air outlet pipe. The air outlet baffle is used to disperse the hot air and prevent the hot air from directly reaching the upper shell and causing the outer shell temperature to be too high. The outer chamber, the upper smoke guide outer cylinder, and the outer chamber are vertically aligned, and the upper smoke guide inner cylinder and the inner chamber are vertically aligned.

[0032] A fan 18 is installed on the upper port of the smoke-eliminating chamber; multiple top air inlets 5 are opened on the top cover 4 of the housing above the fan; multiple side air inlets 6 are opened on the side of the housing; and an inlet pipe 3 is connected to the housing. After the above components are installed, the inner chamber, lower smoke guide duct, upper smoke guide inner duct, inner annular cavity, and inner cylinder chamber form a chimney for upward flow of flue gas (the periphery of the chimney is relatively closed). The outer cylinder chamber, upper smoke guide outer duct, and outer chamber correspond vertically. The interlayer formed between the outer cylinder chamber and the inner cylinder chamber, the upper smoke guide outer duct and the upper smoke guide inner duct, and the outer chamber and the inner chamber forms a second flow (return) passage. The space between the outer cylinder chamber and the outer annular body of the smoke-eliminating component, the space between the upper smoke guide outer duct and the upper connecting plate, and the space between the outer chamber and the lower connecting plate can all be considered as closed. The fan transports the gas through the interlayer to the interlayer between the inner and outer chambers, and then it flows out from the air outlet and then from the air outlet on the lower cover.

[0033] Three pairs of spring electrodes 35 are mounted on the upper connecting plate, and the three pairs of spring electrodes are located on the same circumference; the upper surface of the lower connecting plate has three pairs of arc-shaped electrode plates. The arc-shaped electrode plates are easy to understand and are not shown in the figure. Thus, only an external power supply needs to be connected inside the upper housing. The power can be introduced into the lower housing through the spring electrodes and arc-shaped electrode plates. Limiting holes are formed on the lower connecting plate. The limiting holes are not shown in the figure. Figure 8 The upper connecting plate has a limiting pin mechanism located below the limiting pin. This mechanism includes a U-shaped base 43 fixedly connected to the upper connecting plate. A hole is formed on the top surface of the U-shaped base, through which a limiting pin 42 passes. A limiting part 46 is fixedly connected to the lower part of the limiting pin. A spring 44 passes through the limiting pin between the limiting part and the top surface of the U-shaped base. A pin hole is formed on the upper connecting plate, through which the lower end of the limiting pin 42 passes. A release rod 45 is fixedly connected to the limiting part, extending out of the housing through an elongated hole. After the limiting pin is engaged in the horizontal side of the L-shaped slot, the spring electrode abuts against the arc-shaped electrode plate, and the limiting pin is inserted into the limiting hole. To release, simply lift the release handle upwards, and the upper and lower housings will rotate relative to each other until the limiting pin aligns with the vertical side of the L-shaped slot, allowing the upper and lower housings to disengage.

[0034] An infrared thermometer 47 is installed on the lower cover for temperature detection. The power supply for this device is external.

[0035] During assembly, the upper connecting plate, upper smoke guide outer cylinder, and its upper components are installed on the upper housing. The lower smoke guide cylinder is connected to the upper smoke guide inner cylinder. The outer chamber and its lower components are fixedly installed on the lower connecting plate. Then, the limiting post and the slot are engaged. After unlocking the device with the unlocking rod, the upper and lower housings are rotated relative to each other until the limiting post aligns with the vertical edge of the L-shaped slot, allowing the upper and lower housings to detach and the moxibustion column 33 to be installed.

[0036] When using this device, the moxa stick is placed in the inner chamber. After the first ignition wire is energized, the moxa stick is lit. After the first ignition wire is de-energized, the moxa stick burns and generates heat and smoke. The heat acts on the moxibustion site through the lower cover. The smoke rises through the chimney formed by the inner chamber, the lower smoke guide, the upper smoke guide inner cylinder, the inner ring cavity, and the inner cylinder. When the second ignition wire is energized, the smoke is burned again after passing through the second ignition wire in the inner cavity, which has the effect of eliminating smoke. The smoke in the chimney is discharged outside the outer cylinder after passing through the exhaust pipe. The hot air is drawn into the fan. At the same time, the fan draws in gas from the top air inlet and the side air inlet. After mixing with the hot air, the gas is cooled. The mixed gas flows through the second process (return) passage to the upper air outlet and the lower air outlet and then flows out. After flowing out from the air outlet on the lower cover, it acts on the moxibustion site.

[0037] In this device, both the first and second ignition wires are nickel-chromium alloy wires with a diameter of 0.8 mm and a resistance of 2.17 Ω / m. The first ignition wire is single-layered, 0.63 meters long, and has a resistance of approximately 1.37 Ω. It can ignite the moxa stick when powered by 10V AC. The second ignition wire is double-layered, 0.63 meters long, and has a resistance of approximately 1.37 Ω. It can ignite the moxa smoke when powered by 16V. After a detailed description of the embodiments of this utility model, those skilled in the art will clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent applications. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model are within the scope of the technical solution of this utility model, and this utility model is not limited to the embodiments exemplified in the specification.
