Description

Technical Field

[0001] This application relates to the field of moxibustion equipment, and more specifically, to a novel moxibustion box. Background Technology

[0002] Moxibustion using moxa sticks or moxa cones on acupoints can have health-preserving, disease-preventing, and therapeutic effects, as well as beautifying the skin. However, holding a moxa cone for extended periods is time-consuming and prone to accidents; therefore, moxibustion boxes are often used instead. The moxa cone is fixed in the moxibustion box, which is then placed or secured to the desired area for moxibustion.

[0003] Excessive heat during moxibustion can burn the skin, while insufficient heat reduces its effectiveness. Therefore, adjustments are necessary to maintain a suitable temperature during moxibustion. A utility model patent titled "Adjustable Moxibustion Box," with publication number CN217339370U, discloses an adjustable moxibustion box. It includes a base and a shell screwed onto the base. The height is adjusted by rotation, controlling the distance between the moxa stick and the skin to regulate temperature and prevent burns. During moxibustion, manual rotation is required. Another utility model patent, also titled "Moxibustion Box," with publication number CN206964807U, discloses a moxibustion box with a box body and a lid. The side wall of the box body has an oxygen inlet communicating with the interior. The oxygen inlet has an adjustment device to regulate its size; adjusting the size of the oxygen inlet regulates the temperature. During moxibustion, the user needs to adjust the temperature by moving the moxa stick up and down or adjusting the size of the air inlet, according to the body's perception. This is inconvenient and can easily cause burns.

[0004] In conclusion, because the perceived temperature varies from person to person and the moxa stick cannot be precisely controlled, the existing moxibustion box structure is not suitable for automatic temperature control. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the existing technology by providing a new type of moxibustion box that solves the problem that the existing moxibustion box structure is not suitable for automatic temperature control because the perceived temperature varies from person to person and the burning process of the moxa stick cannot be precisely controlled.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This application provides a novel moxibustion box, which includes an outer shell, a temperature measuring mechanism, and a lifting mechanism. The outer shell includes a top wall, a side wall, and a bottom wall. A circular hole is provided in the middle of the bottom wall. An air inlet, a temperature measuring hole, and a slit are provided on the side wall. The temperature measuring hole is close to the bottom wall. The height of the air inlet is lower than the lower end of the slit but higher than the temperature measuring hole. The upper end of the slit is close to the top wall. The slit is vertical. An air outlet is provided on the top wall. The temperature measuring mechanism is located at the temperature measuring hole. The lifting mechanism includes a lead screw motor. A slider is fixedly mounted on the lead screw of the lead screw motor. A connecting rod is fixedly connected to the slider. The connecting rod passes through the slit and extends into the interior of the outer shell. The lead screw motor is fixedly mounted on the outer wall of the outer shell.

[0008] Preferably, the width of the slit is 2-5 mm; the length of the slit is three-quarters to four-fifths of the length of the lead screw, and the length of the lead screw above the upper end of the slit is the same as the length of the lead screw below the lower end of the slit.

[0009] More preferably, the inner diameter of the circular hole is 1-8 cm, and is less than two-thirds of the bottom wall diameter of the outer shell body.

[0010] More preferably, the diameter of the circular hole is narrower at the outside and wider at the inside, and the diameter of the circular hole gradually increases from the outside of the outer shell to the inside.

[0011] More preferably, the temperature measuring mechanism is an infrared temperature sensor; the temperature measuring hole is tilted downwards, and the height of the side of the temperature measuring hole near the inside of the outer casing is lower than the height of the side of the temperature measuring hole near the outside of the outer casing.

[0012] More preferably, one end of the connecting rod extending into the interior of the housing body is located on the straight line of the central axis of the circular hole on the bottom wall.

[0013] More preferably, the air inlet includes a plurality of first small holes distributed around the perimeter of the side wall of the outer casing at a corresponding height; the air outlet includes a plurality of second small holes disposed on the top wall of the outer casing; the size of the first and second small holes is 2-5 mm.

[0014] More preferably, a dust-blocking mesh is fixedly installed on the inner wall of the outer casing, and the dust-blocking mesh is located between the temperature measuring hole and the air inlet; the dust-blocking mesh has a mesh structure.

[0015] More preferably, the outer casing includes two detachably fixedly connected upper and lower parts, with the dust filter and temperature measuring hole located in the lower part, and the air inlet and slit located in the upper part.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The moxibustion box of this application has a temperature measuring mechanism and a lifting mechanism on its outer shell. The temperature measuring mechanism is located in a temperature measuring hole on the side wall, close to the round hole on the bottom wall, which is closer to the skin at the moxibustion site for more accurate temperature detection. This application further improves the round hole and the temperature measuring hole to make temperature detection even more accurate. The lifting mechanism controls the up-and-down movement of a slider, which in turn moves a connecting rod up and down. The moxa stick is located at the free end of the connecting rod. The lifting mechanism is a screw motor, which can precisely control the position of the moxa stick, thereby changing the temperature of the skin at the moxibustion site. Therefore, the moxibustion box of this application can accurately detect the temperature of the skin at the moxibustion site and precisely control the position of the moxa stick, making it suitable for automatic temperature control.

[0025] To make the implementation process of this utility model clearer, a detailed description will be provided below in conjunction with the accompanying drawings.

[0026] This utility model provides a novel moxibustion box, such as Figure 1As shown, the moxibustion box includes an outer shell 1, a temperature measuring mechanism 2, and a lifting mechanism 3. The outer shell 1 is made of nylon. Since the moxa stick burns at a high temperature, nylon has flame-retardant and heat-resistant properties and does not easily conduct heat, preventing burns to the user. The outer shell 1 includes a top wall, side walls, and a bottom wall. Its overall shape can be cylindrical or prismatic, such as a triangular prism or a quadrangular prism. A circular hole is provided in the center of the bottom wall of the outer shell 1 for contact with the skin for moxibustion. The heat from the burning moxa stick and the effect of moxibustion reach the skin through this hole. The inner diameter of the circular hole is 1-8 cm, while the common diameter of moxa sticks is 2-7 cm. A slightly larger circular hole allows the heat and effect of the moxa stick to be fully applied to the skin; and a hole smaller than two-thirds the diameter of the bottom wall of the outer shell 1 ensures stable contact between the bottom surface of the moxa stick and the skin. The inner diameter of the circular holes can be the same, or they can be cylindrical holes, or they can be different. Preferably, the diameter of the circular holes is narrower at the outside and wider at the inside, and the diameter of the circular holes gradually increases from the outside of the outer shell body 1 to the inside. The outer diameter of the circular holes is 1-7cm. In this way, on the one hand, the convergence shape makes the force of the moxa stick localized on the skin surface, which improves the moxibustion effect. On the other hand, compared with the right-angled edge of the column, the inclined circular hole wall has a weaker blocking effect on infrared rays, which increases the detection range of the temperature measuring mechanism 2 on the skin, thereby making the temperature detected by the temperature measuring mechanism 2 more accurate.

[0027] The outer casing 1 has an air inlet, a temperature measuring hole, and a slit on its side wall. The air inlet allows air to enter during the burning of the moxa stick, ensuring complete combustion. The temperature measuring hole houses the temperature measuring mechanism 2. The slit houses the lifting mechanism 3, through which a connecting rod can move up and down. Specifically, the air inlet includes multiple small holes, each 2-5mm in size, distributed around the perimeter of the side wall of the outer casing 1 at a corresponding height. This allows surrounding air to enter the interior of the outer casing 1 from various directions, providing oxygen for the burning of the moxa stick. The temperature measuring hole is located near the bottom wall, and the height of the air inlet is below the lower end of the slit but above the temperature measuring hole. The upper end of the slit is near the top wall, and the slit is vertical. The temperature measuring mechanism 2 is an infrared temperature sensor, such as the GY-906-BCC infrared temperature sensor. Figure 2 As shown, the temperature measuring mechanism 2 is fixedly mounted on the temperature measuring hole. It can be fixed in one way or fixed but detachable. For example, the outer diameter of the cylindrical portion of the infrared temperature sensor forms a friction pair to fix the infrared temperature sensor. The inner diameter of the temperature measuring hole is slightly larger than the outer diameter of the cylindrical portion of the infrared temperature sensor, and the two are matched. The central axis of the temperature measuring hole can be perpendicular to the sidewall or not. Preferably, the temperature measuring hole is tilted downwards, meaning the height of the side of the temperature measuring hole closer to the inside of the outer casing 1 is lower than the height of the side closer to the outside of the outer casing 1. In this way, the probe of the temperature measuring mechanism 2 faces the circular hole on the bottom wall, i.e., the temperature measuring mechanism 2 faces the skin being treated with moxibustion, resulting in more accurate temperature detection.

[0028] The lifting mechanism 3 includes a lead screw motor, a slider, and a connecting rod, such as... Figure 3 As shown, this is a stepper motor with a lead screw and a slider. The slider is fixedly mounted on the lead screw of the lead screw motor, and the connecting rod ( Figure 3 (Not shown in the drawing) is fixedly connected to the slider, and the connecting rod extends through the slit into the interior of the outer casing 1. The lead screw motor is fixedly mounted on the outer wall of the outer casing 1. The lead screw motor can be fixed to the outside of the side wall of the outer casing 1 by means of adhesive bonding, snap-fit ​​fixing, threaded fixing, etc. Figure 3 As shown, when the lead screw motor is working, the lead screw rotates. Through the interaction of the external thread of the lead screw and the matching internal thread of the slider, the rotation of the lead screw is converted into the up-and-down movement of the slider. The slider is fixedly connected to one end of the connecting rod, and the other end of the connecting rod is fixedly fitted with the moxa stick during use. Changing the rotation direction of the lead screw in the lead screw motor changes the movement direction of the slider. In other words, the rotation direction of the lead screw controls the upward and downward movement of the moxa stick, thereby changing the distance between the burning moxa stick and the skin, thus regulating the temperature. Under the action of the lifting mechanism 3, when the moxa stick descends, the distance between it and the skin decreases, and the skin temperature increases; when the moxa stick rises, the distance between it and the skin increases, and the skin temperature decreases; thus, it regulates the skin temperature.

[0029] The slit width is 2-5mm. There can be one or two slits; one slit is convenient for preparation. Two slits, parallel to each other, with a distance less than the diameter of the moxa stick, correspond to two connecting rods, each passing through one slit. This ensures the moxa stick is more stable and less likely to fall during use. The slit width is greater than the outer diameter of the connecting rod, allowing it to pass through. During the up-and-down movement of the connecting rod, there is no interaction between the connecting rod and the edge of the slit, resulting in more accurate control of the moxa stick's position. The slit length is three-quarters to four-fifths of the lead screw length. The length of the lead screw above the upper end of the slit is the same as the length below the lower end. This keeps the slider's movement within the middle of the lead screw, preventing slippage or sluggish movement near the edge. Preferably, two limiting devices can be installed at corresponding heights at both ends of the slit to limit the slider's movement, preventing the moxa stick from getting too close to the skin and causing accidental burns. The limiting device can be a limit switch or other limiting device; the limiting device is fixedly installed on the outer wall of the outer shell 1 or on the vertical rod of the two fixed sliders parallel to the lead screw in the lead screw motor.

[0030] One end of the connecting rod extends into the outer casing 1 and is aligned with the central axis of the circular hole on the bottom wall; in this way, the heat and effect generated by the burning moxa stick are transferred vertically downwards to the skin, resulting in better moxibustion effects. The other end of the connecting rod can be horizontal or vertical; the former prevents the moxa stick from falling during its up-and-down movement, while the latter allows for a longer moxa stick to be placed vertically, thus reducing the frequency of moxa stick replacements.

[0031] The top wall of the outer shell 1 is provided with air vents, which are multiple secondary small holes, each 2-5mm in size. The smoke produced by moxibustion rises and is discharged through the air vents. At the same time, air convection is formed between the air inlet and outlet, providing sufficient oxygen for the combustion process of the moxa stick and ensuring complete combustion. Incomplete combustion of the moxa stick will produce more smoke and unpleasant odors, containing carbon monoxide and particulate pollutants, which are detrimental to human health. Incomplete combustion of the moxa stick also wastes energy.

[0032] Preferably, to prevent the ash from the moxa sticks from burning the skin, a ash-blocking net is fixedly installed on the inner wall of the outer shell 1. The ash-blocking net has a mesh structure that can block falling ash, preventing it from continuing to fall, but it will not prevent the heat generated during moxibustion and the effects of moxibustion from reaching the skin. The ash-blocking net can be fixed by providing protrusions, slots, etc., on the inner wall of the outer shell 1, or by adhesive, screwing, etc. One structure of the ash-blocking net is as follows: Figure 4 The example shown is merely one illustration. Specifically, the ash-blocking mesh is positioned between the temperature measuring hole and the air inlet; that is, the height of the ash-blocking mesh is higher than the height of the temperature measuring hole, so that the ash-blocking mesh will not affect the temperature detection process of the temperature measuring mechanism 2; and the height of the ash-blocking mesh is lower than the air inlet, so that the air entering through the air inlet moves upward and will not affect the ash. Otherwise, the ash would be dispersed in all directions by the incoming air, reducing the accuracy of temperature detection and causing people to inhale particulate pollutants.

[0033] Furthermore, to facilitate cleaning of moxa ash and replacement of moxa sticks, the outer casing 1 comprises two detachably and fixedly connected upper and lower parts. The upper part includes an air inlet and a slit (including the top wall), while the lower part includes an ash-blocking mesh and a temperature measuring hole (including the bottom wall). Thus, when it is necessary to replace the moxa stick or clean the moxa ash, the upper and lower parts can be separated; when moxibustion is needed, the upper and lower parts can be fixedly connected together. The upper and lower parts can be connected via matching threads, snap-fit ​​connections, or by using matching bosses with different cross-sectional radii to form a friction pair.

[0034] In addition, to achieve automatic temperature control in the moxibustion box of this application, the temperature signal from the temperature measuring mechanism 2 needs to be transmitted to the control module, which can be a microcontroller, chip, etc. The control module determines whether the temperature at the skin is greater than or less than a preset temperature according to the program. When the temperature at the skin is greater than the preset temperature, the control module controls the lifting mechanism 3 to move upward, increasing the distance between the skin and the moxa stick and lowering the skin temperature. When the temperature at the skin is less than the preset temperature, the control module controls the lifting mechanism 3 to move downward, decreasing the distance between the skin and the moxa stick and raising the skin temperature, thereby maintaining the skin temperature at the preset temperature and achieving automatic temperature control. The control module receives the temperature signal, determines whether it is within the preset temperature (or range) according to the algorithm, and then controls the lifting mechanism 3 to move the connecting rod up and down. The power supply for the temperature measuring mechanism 2 and the lifting mechanism 3 is also an existing technology. There are many ways to achieve the above process in the prior art. The control module includes CPUs, microcontrollers, etc., and the connection methods include wired signal transmission and wireless signal transmission, etc. Furthermore, the preset temperature can be set on a mobile terminal or a dedicated touch screen, etc. Since the control process is not the subject matter of utility model protection, it will not be described in detail in this application.

[0035] The control process in this embodiment will be briefly described below. Figure 5 This is a schematic diagram of a moxibustion box that includes components such as a touch screen slot and straps, and has a shape similar to a triangular prism. Figure 6 This is an example of a temperature control process. Specifically, it mainly includes a control module, a temperature measuring mechanism 2, and a lifting mechanism 3; the power supply powers the control module, as well as the lifting mechanism 3 and the temperature measuring mechanism 2. Figure 6(Not shown in the diagram) The switch controls the on / off state of the circuit. The limit device limits the movement range of the slider in the lifting mechanism 3. The touchscreen allows users to interact with the device, such as inputting preset temperature, moxibustion duration, and displaying prompts. This information is not essential and can be preset in the program. The temperature measuring mechanism 2 monitors the temperature of the skin surface at the moxibustion site and feeds it back to the control module. The detected temperature is compared with the preset temperature, and the lifting mechanism 3 is controlled accordingly. The control module controls the slider in the lifting mechanism 3 to move up and down, and the moxibustion column connected to the slider via a connecting rod moves up and down with the slider. If the detected temperature is higher than the preset temperature, the lifting mechanism 3 controls the moxibustion column to rise, moving away from the skin to lower the temperature. If the detected temperature is lower than the preset temperature, the lifting mechanism 3 controls the moxibustion column to fall, moving closer to the skin to raise the temperature, maintaining the skin temperature at the preset temperature to avoid burns or poor moxibustion effect. When the slider touches the limit module, the limit module sends a feedback signal to the control module, and the control module sends a stop command to stop the slider from moving. The switch acts as a power switch to control the power supply to the control module, i.e., to control the state of the device. The power supply can be DC, with an external power cord connected to the socket to power the control module. Additionally, a fixed moxibustion time can be set in the program. When the set time is reached, the user is notified via the touchscreen, and the moxa stick is raised to its highest position to end the moxibustion. This saves on manual monitoring costs, improves efficiency, and enhances safety.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
