Description

Technical Field

[0001] This invention relates to the field of air purification technology, and in particular to an air purification device for a rowing machine and its usage method. Background Technology

[0002] Air purifiers are household appliances that effectively improve air cleanliness. They typically circulate indoor air through components like motors and fans, then remove or adsorb various pollutants from the air using an internal air filter. Finally, ionized negative ions are returned to the indoor space, thus purifying the air. Currently, most air purifiers on the market are powered by electricity. In response to global carbon neutrality and energy conservation initiatives, devices combining fitness equipment and air purifiers (such as exercise bikes with integrated air purifiers) are emerging. These utilize the mechanical energy generated during exercise to power the air purifier, reducing electricity consumption. However, these devices generally suffer from the following problems: long power transmission strokes, numerous power transmission mechanisms, low power conversion efficiency, poor operational stability, and the inability to store and reuse energy. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an air purification device for rowing machines. This device has a compact power transmission mechanism with strong stability and energy storage function, which can better realize the full utilization of the energy generated by exercise to achieve the effect of air purification, so that exercise and health can be accompanied by respiratory health.

[0004] Another object of the present invention is to provide a method of using the above-mentioned rowing machine air purification device.

[0005] The technical solution of the present invention is: an air purification device for a rowing machine, comprising a main unit, a slide rail and a sliding pad, wherein the main unit is located at one end of the slide rail and the sliding pad is slidably disposed on the slide rail;

[0006] The main unit houses a flywheel, power transmission mechanism, impeller, and air purification components. The flywheel and impeller are coaxially connected and rotate synchronously. The power transmission mechanism is located on one side of the flywheel, and the air purification components are located on the other side of the impeller. The main unit's outer casing has air inlets and outlets, and a handle is located on the outside, connected to the power transmission mechanism. The main unit, as the core of the rowing machine air purification system, converts the mechanical energy generated during the user's exercise into power for the impeller and air purification components. This power is then used to circulate and purify indoor air, creating a zero-power air purification device that promotes both physical and respiratory health. Inside the main unit, the power conversion mechanism, formed by the combination of the flywheel and impeller, utilizes the flywheel's excellent energy storage capacity to provide stable power to the impeller. Integrating the flywheel, power transmission mechanism, impeller, and air purification components into the main unit results in a compact power mechanism and a short power transmission stroke, improving power conversion efficiency.

[0007] The wind turbine is located on one side of the flywheel, and the diameter of the wind turbine is smaller than that of the flywheel. Multiple connecting blades are distributed on the outer periphery of the wind turbine, and an air outlet is formed between any two adjacent connecting blades. The air outlet is connected to the air outlet on the main unit casing.

[0008] The power transmission mechanism includes a driven gear, a transmission chain, a driving gear, a flat belt, a rope reel, and a spring reel. The flat belt is wound around the rope reel, and one end of the flat belt is fixedly connected to the handle. The spring reel is coaxially located inside the rope reel and rotates synchronously with the rope reel. The driving gear is located on one side of the rope reel and coaxially connected to the rope reel via a first connecting shaft. The driving gear is connected to the driven gear via the transmission chain. The driven gear is located on one side of the flywheel and coaxially connected to the flywheel via a second connecting shaft. When the user exercises, they hold the handle and pull the flat belt, causing the rope reel to rotate. The rope reel drives the driving gear to rotate synchronously via the first connecting shaft. The driving gear drives the driven gear to rotate via the transmission chain. The driven gear drives the flywheel to rotate via the second connecting shaft. During the rotation of the flywheel, the kinetic energy generated by the rotation is stored in the flywheel, and this stored kinetic energy is used to drive the impeller to rotate synchronously, thereby driving the impeller and air purification components to work. The specific connection structure between the spring reel and the rope reel is the same as the existing spring reel's usage and installation structure. The spring reel is mainly used to drive the rope reel to rotate in the opposite direction when reset is required, so as to retract and wind the flat strip, preparing it for the next traction use.

[0009] A structural support frame is also provided on the outside of the power transmission mechanism. The two ends of the first connecting shaft are mounted on the structural support frame, and the two ends of the second connecting shaft are also mounted on the structural support frame. This structural support frame is located inside the main unit and mainly provides a mounting base for the various components of the power transmission mechanism.

[0010] The driven gear plate has multiple stages, with ratchet wheels (also known as overrunning clutches) connecting them. Each stage of the driven gear plate is coaxially arranged via ratchet wheels. The driving gear plate is connected to one of the driven gear plates via a transmission chain. A gear shifter and auxiliary gear are located on the outside of the driven gear plate. The driving gear plate, driven gear plate, gear shifter, and auxiliary gear are connected by a transmission chain. A shift adjuster is also located on the outside of the driving gear plate, with a shift adjustment wire connecting it to the gear position adjuster. Through the cooperation of the shift adjuster, gear position adjuster, shift adjustment wire, and auxiliary gear, the transmission sprocket can shift gears between the stages of the driven gear plate (its shifting principle is the same as that of a traditional shifting device). By shifting gears, the grip pulling force can be changed, thus adapting to the fitness needs of different users.

[0011] The air purification component includes a filter and activated carbon. The filter is located inside the air inlet on the main unit casing, and the activated carbon is filled inside the filter. The air outlet side of the filter is connected to the air inlet side of the impeller. The filter can be a HEPA filter; the combination of activated carbon and a HEPA filter achieves highly efficient indoor air purification.

[0012] The main unit also has a shock-absorbing support rod at its bottom, and a limiting groove is provided on the top surface of the slide rail below the main unit. One end of the shock-absorbing support rod is hinged to the bottom of the main unit, and the other end of the shock-absorbing support rod is a round shaft end located in the limiting groove, with the axis of the round shaft end parallel to or coincident with the axis of the limiting groove. Furthermore, the limiting groove can be provided in multiple stages. By placing the shock-absorbing support rod in different limiting grooves, the angle of the main unit relative to the slide rail can be adjusted, thereby adjusting the height of the grip to suit the user's needs.

[0013] Foot support plates are also provided on both sides of the slide rail, with the foot support plates located at the end of the slide rail closer to the main unit; anti-slip brackets are also provided at the bottom of the slide rail. The foot support plates are installed in the limiting holes on the side of the slide rail by means of pins, and the installation angle of the foot support plates can be adjusted and set according to actual needs. In addition, the foot support plates are also provided with bandages, which can be used to fix the soles of the feet when the user uses them.

[0014] The slide rail includes a first slide rail section and a second slide rail section connected together. A hinge element for folding is provided at the connection between the first slide rail section and the second slide rail section. The hinge element can be a commercially available hinge element or hinge mechanism, etc. The setting of the hinge element enables the slide rail to be foldable, reducing the footprint of the entire rowing machine air purification equipment and making it convenient for users to store when not in use.

[0015] The present invention discloses a method for using the above-mentioned rowing machine air purification device, specifically as follows: During use, the user moves along the slide rail using the sliding mat during exercise, and simultaneously pulls the handle to move along with it. When the handle moves, the flywheel is driven to rotate through the power transmission mechanism. During the rotation of the flywheel, on the one hand, the kinetic energy generated by the rotation is stored in the flywheel, and on the other hand, the stored kinetic energy is used to drive the fan wheel to rotate synchronously. When the fan wheel rotates, indoor air is drawn into the main unit from the air inlet, first purified by the air purification component, and then clean air is sent out from the air outlet under the action of the fan wheel's rotation.

[0016] When the energy output of a user's exercise is uneven, the kinetic energy stored in the flywheel is used to drive the flywheel to continue rotating at high speed to purify the air.

[0017] The principle behind the aforementioned rowing machine air purification equipment and its usage is as follows: Utilizing the combination of a flywheel and a fan, the mechanical energy generated during the user's exercise is stored and converted through the reciprocating motion of the body. This energy is then transformed into the directional high-speed rotation of the fan, drawing indoor air in through the air inlet on one side of the main unit. After being drawn in, the air is first filtered and purified by the air purification components before being expelled from the air outlet following the high-speed rotation of the fan, forming a circulating purification of indoor air. This achieves simultaneous improvement in the user's physical and mental health and respiratory health without consuming electricity. The flywheel's energy storage function provides stable rotation for the high-speed fan, and also allows the fan to continue operating for a period of time after the user intermittently stops exercising. Furthermore, integrating the flywheel, power transmission mechanism, fan, and air purification components into the main unit results in a compact power mechanism and a short power transmission stroke, which improves power conversion efficiency.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] This rowing machine air purification device and its usage method organically combine a rowing machine for fitness with various components that have air purification functions. In the main unit, the combination of a flywheel and a fan wheel stores and converts the mechanical energy generated during the user's exercise, driving the fan wheel to rotate at high speed to bring indoor air into the main unit for circulation and purification. At the same time, its power transmission mechanism has a compact structure, strong stability and energy storage function, and can make good use of the energy generated by exercise to achieve the effect of air purification, so that fitness and health will be accompanied by respiratory health.

[0020] In this rowing machine air purification device, a multi-stage driven gear is connected to the outside of the flywheel via a ratchet. With the use of components such as the shift regulator and gear adjuster, the grip pull can be changed by shifting gears, thus adapting to the fitness needs of different users. It is flexible in use. At the same time, the installation angle of the foot support plate and the height of the grip are also adjustable, making this rowing machine air purification device suitable for different groups of people and with a wide range of applications.

[0021] The slide rails in this rowing machine air purification device have a foldable structure, which takes up little space and makes it easy for users to store. Attached Figure Description

Detailed Implementation

[0034] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0035] Example 1

[0036] This embodiment describes an air purification device for a rowing machine, such as... Figure 1 or Figure 3 As shown, it mainly includes a main unit 1, a slide rail 2, and a sliding pad 3. The main unit is located at one end of the slide rail, and the sliding pad slides on the slide rail. A handle 4 is located on the outside of the main unit, and a foot support plate 5 is also provided on the slide rail. The specific structure of each mechanism is as follows:

[0037] like Figure 2 or Figure 4 As shown, the main unit contains a flywheel 6, a power transmission mechanism, a fan wheel 7, and an air purification component. The flywheel and fan wheel are coaxially connected and rotate synchronously. The power transmission mechanism is located on one side of the flywheel, and the air purification component is located on one side of the fan wheel. The main unit's outer casing has an air inlet 8 (e.g., ...). Figure 2 or Figure 5 (as shown) and air outlet 9 (as shown) Figure 1 As shown, a handle is located on the outside of the main unit, and the handle is connected to the power transmission mechanism. The main unit, as the core mechanism of the entire rowing machine air purification equipment, converts the mechanical energy generated during the user's exercise into power for the impeller and air purification components. This power is then used to circulate and purify indoor air, thus creating a zero-power air purification device that simultaneously promotes the user's physical and mental health and respiratory health. Inside the main unit, a power conversion mechanism formed by the combination of a flywheel and an impeller utilizes the flywheel's excellent energy storage capacity to provide stable power to the impeller. Integrating the flywheel, power transmission mechanism, impeller, and air purification components into the main unit results in a compact power mechanism and a short power transmission stroke, which improves power conversion efficiency.

[0038] The power transmission mechanism includes a driven gear 10, a transmission chain 11, a driving gear 12, a flat belt 13, a rope spool 14, and a spring spool (not shown in the figure). The flat belt is wound around the rope spool, and one end of the flat belt is fixedly connected to the handle. The spring spool is coaxially located inside the rope spool and rotates synchronously with the rope spool. The driving gear 13 is located on one side of the rope spool and coaxially connected to the rope spool through a first connecting shaft. The driving gear 13 is connected to the driven gear 14 through the transmission chain. The driven gear 14 is located on one side of the flywheel and coaxially connected to the flywheel through a second connecting shaft. When the user exercises, they hold the handle and pull the flat belt, which causes the rope spool to rotate. The rope spool drives the driving gear 14 to rotate synchronously through the first connecting shaft. The driving gear 13 drives the driven gear 14 to rotate through the transmission chain. The driven gear 14 drives the flywheel to rotate through the second connecting shaft. During the rotation of the flywheel, the kinetic energy generated by the rotation is stored in the flywheel. On the other hand, this stored kinetic energy is used to drive the impeller to rotate synchronously, thereby driving the impeller and air purification components to work. The specific connection structure between the mainspring reel and the rope reel is the same as the existing mainspring reel's usage and installation structure. The mainspring reel is mainly used to drive the rope reel to rotate in the opposite direction when reset is needed, rewinding the flat strip and preparing for the next traction operation. A structural support frame 15 is also provided on the outside of the power transmission mechanism. The two ends of the first connecting shaft are mounted on the structural support frame, and the two ends of the second connecting shaft are also mounted on the structural support frame. This structural support frame is located inside the main unit and mainly provides the mounting foundation for the various components of the power transmission mechanism. The driven gear has multiple stages (ten stages in this embodiment), with ratchet 16 (also called an overrunning clutch) between each stage. Each stage of the driven gear is coaxially arranged via the ratchet. The driving gear is connected to one of the driven gear stages via a transmission chain. A gear shifter 17 and an auxiliary gear 18 are located on the outer side of the driven gear. The driving gear, driven gear, gear shifter, and auxiliary gear are connected via a transmission chain. A shift adjuster 19 is also located on the outer side of the driving gear, with a shift adjustment wire 20 between the shift adjuster and the gear position adjuster. Through the cooperation of the shift adjuster, gear position adjuster, shift adjustment wire, and auxiliary gear, the transmission sprocket can shift gears between each stage of the driven gear (its shifting principle is the same as that of a traditional shifting device). Shifting gears changes the grip pull, thus adapting to the fitness needs of different users.

[0039] The air purification component includes a filter 21 and activated carbon (not shown in the figure). The filter is located inside the air inlet on the main unit casing, and the activated carbon is filled inside the filter. The air outlet side of the filter is connected to the air inlet side of the impeller. The filter can be a HEPA filter; the combination of activated carbon and a HEPA filter achieves highly efficient indoor air purification.

[0040] As shown in Figure 6(a) or Figure 6(b), the wind turbine is located on one side of the flywheel, and the diameter of the wind turbine is smaller than that of the flywheel. Multiple connecting blades 7-1 are distributed on the outer periphery of the wind turbine. An air outlet 7-2 is formed between any two adjacent connecting blades, and the air outlet is connected to the air outlet on the main unit casing.

[0041] In addition, the bottom of the main unit is equipped with a shock-absorbing support rod 22, and the top surface of the slide rail below the main unit is provided with a limiting groove 23. One end of the shock-absorbing support rod is hinged to the bottom of the main unit, and the other end of the shock-absorbing support rod is a round shaft end 22-1, which is located in the limiting groove, and the axis of the round shaft end is parallel to or coincides with the axis of the limiting groove. Furthermore, the limiting groove can be provided in multiple stages. By setting the shock-absorbing support rod in different limiting grooves, the angle of the main unit relative to the slide rail can be adjusted, thereby adjusting the height of the grip to adapt to the user's needs.

[0042] Of the foot support plates on both sides of the slide rail, the foot support plate is located on the slide rail at the end closer to the main unit; for example... Figure 3 or Figure 5 As shown, the foot support plate is installed in the limiting hole 25 on the side of the slide rail via the pin 24. The installation angle and position of the foot support plate can be adjusted and set according to actual needs. In addition, the foot support plate is also equipped with a bandage 26, which can be used to fix the foot when the user uses it.

[0043] The bottom of the slide rail is also equipped with an anti-slip bracket 27.

[0044] The slide rail includes a first slide rail section and a second slide rail section connected together. A hinge element 28 for folding is provided at the connection point between the first and second slide rail sections. The hinge element can be a commercially available hinge or hinge mechanism (a hinge element is used in this embodiment). The hinge element enables the slide rail to be foldable, reducing the footprint of the entire rowing machine air purification device and facilitating storage when not in use. Its folded state is as follows: Figure 8 As shown.

[0045] The main unit's casing also features a display 29 and a dial 30 (e.g., ...). Figure 1 As shown in the image, this allows users to easily understand fitness data and gear shifting status. The display provides visualized exercise energy data, such as calories burned during exercise, energy conversion data, fan work data, air purification data, and real-time air quality parameters of the fitness environment.

[0046] The principle of the above-mentioned rowing machine air purification equipment is as follows: Figure 7As shown, by combining a flywheel and a fan, the mechanical energy generated during a user's exercise is stored and converted into the directional high-speed rotation of the fan. This causes indoor air to be drawn in through the air inlet on one side of the main unit. After being drawn in, the air is filtered and purified by the air purification components before being expelled from the air outlet following the high-speed rotation of the fan, forming a circulating purification of indoor air. This achieves simultaneous improvement in the user's physical and mental health and respiratory health without consuming electricity. The flywheel's energy storage function provides stability for the high-speed rotation of the fan and also allows the fan to continue operating for a period of time after the user stops exercising. Furthermore, by integrating the flywheel, power transmission mechanism, fan, and air purification components into the main unit, the power mechanism is compact and the power transmission stroke is short, which helps to improve power conversion efficiency.

[0047] Example 2

[0048] This embodiment describes the usage method of the rowing machine air purification device described in Embodiment 1. Specifically, during use, the user, while exercising, uses their feet to step on the pedals, coordinating the force of their legs and waist to move the sliding mat along the slide rail. Simultaneously, the user pulls the handle to move along with the mat. As the handle moves, the flat belt drives the active gear disc to rotate, which in turn drives the flywheel to rotate through the power transmission mechanism. During the flywheel's rotation, the kinetic energy generated by the rotation is stored within the flywheel. Furthermore, this stored kinetic energy is used to drive the fan wheel to rotate synchronously. When the fan wheel rotates, indoor air is drawn into the main unit from the air inlet. After being purified by the air purification components, clean air is then delivered out from the air outlet under the action of the fan wheel's rotation. When the user's energy output during exercise is uneven, the kinetic energy stored in the flywheel is used to drive the flywheel to continue rotating at high speed for air purification.

[0049] The specific operating procedure is as follows:

[0050] (1) The user sits on the sliding mat, places his feet on the foot support plate (the angle of which can be pre-adjusted according to the user's actual needs), and fixes his feet with bandages;

[0051] (2) Pull the handle and push your body backward to make the sliding pad slide backward along the slide rail. Under the pull of the slack, the rope disc rotates.

[0052] (3) The rope disc rotates, which drives the active gear disc to rotate synchronously through the first connecting shaft. During this process, the gear can be shifted through the gear shifter to change the magnitude of the grip pull force so as to adapt it to the user's own situation.

[0053] (4) The driving gear rotates and drives the driven gear to rotate through the transmission chain. The driven gear can only rotate in one direction under the action of the ratchet (i.e., overrunning clutch).

[0054] (5) The active gear disk drives the flywheel to rotate synchronously through the second connecting shaft. While the flywheel drives the wind turbine to rotate, most of the kinetic energy generated by the rotation of the flywheel will be stored in the flywheel. The higher the stored energy, the higher the speed of the wind turbine.

[0055] (6) The rotation of the impeller will draw indoor air in through the air inlet. After being filtered and purified by the purification components, the air is sent out through the air outlet under the drive of the impeller, thus achieving air circulation and purification.

[0056] (7) When the user stops exercising, the flywheel will continue to rotate because it has stored a certain amount of energy. The wind turbine will also run for a period of time under the drive of the flywheel. The only energy loss during this period is the wind resistance and the friction loss of the mechanical bearing on the second connecting shaft.

[0057] (8) After the equipment finishes running, the equipment is reset. The user pulls the handle and moves forward. The rope reel will reverse under the action of the spring reel, thereby achieving retraction and stretching, and preparing for the next traction work.

[0058] As described above, the present invention can be well implemented. The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention; that is, all equivalent changes and modifications made in accordance with the content of the present invention are covered by the scope of protection claimed in the claims of the present invention.
