Description

Technical Field

[0001] This invention relates to the field of water heaters, and in particular to a connecting device and a heat exchange device. Background Technology

[0002] A gas water heater generally consists of a fluid system and a heat exchanger. The fluid system includes an inlet channel, a heat exchange channel, and an outlet channel, connected sequentially. The heat exchange channel corresponds to the heat exchanger of the gas water heater. The inlet channel is connected to the tap water pipe, and the user's water valve is connected to the outlet channel. During the use of a gas water heater, if the water valve is opened for a period of time and then closed, and then reopened shortly afterward, the water temperature at the outlet will successively pass through several stages: slightly lower temperature, very higher temperature, very lower temperature, and suitable temperature. The slightly lower temperature stage is caused by a slight decrease in temperature of residual hot water in the outlet channel within a short period of time. The very higher temperature stage is caused by the temperature rise due to water supply interruption. When the gas water heater stops working, the residual flue gas temperature in the heat exchanger continues to heat the water in the heat exchange channel, making the water temperature in the heat exchange channel higher than the normal operating temperature; this phenomenon is called intercalated hot water. The very lower temperature stage is caused by the residual cold water in the inlet channel entering the heat exchange channel when the gas water heater is turned on again, which cannot be heated to the target temperature; this phenomenon is called intercalated cold water. The presence of hot and cold water in the interlayer can affect user experience, and the hot water in the interlayer may even cause scalding.

[0003] In existing technology, a bypass pipe is installed between the inlet and outlet channels as a connecting channel. After the gas water heater is turned off, the bypass pipe is opened, and a pump provides power to circulate the water in the inlet channel, heat exchange channel, outlet channel, and bypass pipe, thereby avoiding the formation of interlayered hot and cold water. However, using a pump to provide power is costly and inconvenient to install. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art, which is that gas water heaters use pumps to provide power to solve the problem of hot water and cold water in the jacket, resulting in high cost and inconvenient installation. The present invention provides a connection device and a heat exchange device.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A connecting device includes a base, a connecting channel for fluid flow is formed between a first end and a second end of the base, one end of the first end and the second end are connected to an inlet channel of a fluid system, and the other end is connected to an outlet channel of the fluid system. The connecting device further includes:

[0007] A power component is rotatably disposed at the first end relative to the base;

[0008] The moving component is poweredly connected to the power component;

[0009] A potential energy element has a movable end and a fixed end, the movable end being connected to the movable component, and the fixed end being connected to the base, the potential energy element being used to store elastic potential energy and / or magnetic potential energy;

[0010] When fluid flows at the first end, the fluid can drive the power component to rotate relative to the base, causing the moving component to move the moving end in the forward direction and disconnect the first end and the second end; after the fluid at the first end stops flowing, the moving end drives the moving component to move in the reverse direction and connect the first end and the second end, thereby causing the power component to rotate to drive the fluid at the first end to flow.

[0011] In this design, the first and second ends of the connecting device are connected, one end to the inlet channel and the other end to the outlet channel, forming a bypass channel for the fluid system. The fixed end of the potential energy element is connected to the base for positioning, and the movable end is connected to the movable component, moving forward with the movable component to store potential energy or releasing potential energy to drive the movable component to move in the opposite direction. The power element is located at the first end, at the junction of the connecting channel and the inlet or outlet channel, so that the flow of fluid in the inlet or outlet channel can drive the power element to rotate, and vice versa. By setting a power connection between the movable component and the power element, the rotation of the power element can drive the movable component to move, and the movement of the movable component can drive the power element to rotate, thereby realizing the conversion between linear motion and rotation. This allows the movable end of the potential energy element to change its distance from the fixed end by moving to store or release potential energy.

[0012] When using the fluid system, the fluid in the inlet and outlet channels is flowing, causing the fluid at the first end to flow and drive the power component to rotate relative to the base. The rotation of the power component drives the moving component to move forward to isolate the first end and the second end, preventing the fluid in the inlet channel from entering the outlet channel through the connecting channel, thereby preventing the connecting device from interfering with the normal use of the fluid system. When the moving component moves forward, it drives the moving end of the potential energy component to move forward, so that the potential energy component stores potential energy.

[0013] After the fluid system is stopped, the fluid in the inlet and outlet channels ceases to flow, the power component stops rotating, and the moving component stops moving. At this time, the potential energy component moves in the opposite direction through its moving end to release its stored potential energy. The reverse movement of the moving end drives the moving component to move in the opposite direction, causing the moving component to drive the power component to rotate, thus disturbing the fluid at the first end. This allows the fluid to flow within the circulation channel formed by the connecting channel, inlet channel, and outlet channel. When the connecting device is installed in the fluid system of a gas water heater, it can prevent the layering of hot and cold water.

[0014] Power is provided by fluid flow, causing the power component to rotate and storing potential energy in the potential energy component. After the fluid stops flowing, the stored potential energy is released through the potential energy component, causing the power component to rotate again and drive the fluid flow. Since the power source is fluid, no additional power source is required, reducing costs and eliminating the need to consider power source installation, making the connection device easy to install. The connection device is a mechanical structure, requiring no electricity and offering high reliability.

[0015] Preferably, the connecting device further includes a transmission component, and the power component, the transmission component, and the moving component are sequentially connected by power.

[0016] In this solution, by setting a transmission component to connect the power component and the moving component, the installation requirements of the power component and the moving component can be reduced. It is convenient to set the power component at the connection point between the connecting channel and the inlet channel or the outlet channel, and it is convenient for the moving component to isolate and connect the first end and the second end.

[0017] Preferably, the transmission component and the power component are fixedly connected, and when the transmission component rotates with the power component, it can drive the moving component to move, and when the moving component moves, it can drive the transmission component to rotate.

[0018] In this design, the transmission components and power components are fixedly connected, resulting in a simple and compact structure with reliable transmission.

[0019] Preferably, the connecting device further includes a plug connected to the movable member, the shape of the plug matching the shape of the connecting channel to isolate the first end and the second end.

[0020] In this solution, compared to directly separating the first and second ends of the moving part, setting a plug on the moving part to separate the first and second ends reduces the requirements for the shape and size of the moving part, and facilitates the processing and installation of the moving part.

[0021] Preferably, the potential energy element includes a first potential energy element, one end of which is connected to the fixed end and the base, and the other end is connected to the plug;

[0022] The plug and the movable component are directly connected;

[0023] Alternatively, the potential energy component may further include a second potential energy component, one end of which is connected to the plug, and the other end of which is connected to the moving end and the moving component.

[0024] In this design, the structure is simple when the plug and the moving part are directly connected.

[0025] When the plug and the moving part are indirectly connected through the second potential energy element, on the one hand, the position requirements of the plug and the moving part can be reduced, making it easier to set up the plug and the moving part; on the other hand, when a transmission part is provided, interference between the plug and the transmission part can be avoided.

[0026] Preferably, the first potential energy element and the second potential energy element are elastic elements used to store elastic potential energy.

[0027] In this design, the first and second potential energy components are elastic elements, resulting in a simple structure and low cost. Furthermore, the shape of the elastic element and its connected parts complement each other to constrain the direction of motion.

[0028] Preferably, the wall of the connecting channel is formed with a narrow opening connecting the first end and the second end. When the moving member moves forward, it moves closer to the narrow opening to block the narrow opening, and when the moving member moves in the reverse direction, it moves away from the narrow opening to open the narrow opening.

[0029] In this solution, by setting a narrow opening to connect the first end and the second end, the structure of the connecting channel can be simplified, and the narrow opening can be blocked or opened when the moving part moves.

[0030] Preferably, the narrow opening is funnel-shaped with the opening facing the first end, and the connecting device further includes a plug disposed between the first end and the narrow opening. The plug is connected to the movable member, and the shape of the plug matches the shape of the narrow opening to separate the first end and the second end.

[0031] In this design, the narrow opening is funnel-shaped, allowing it to open only in one direction. Furthermore, the opening of the narrow opening faces the first end, and the plug is positioned between the first end and the narrow opening. When the connecting device is connected to the fluid system, and the first end is used to connect to the inlet channel, the fluid tends to flow from the first end to the narrow opening. The fluid pressure acting on the plug also facilitates the plug sealing the narrow opening.

[0032] Preferably, the moving member and the potential energy member are arranged sequentially from the first end to the second end.

[0033] In this design, the moving component and the potential energy component are arranged in series, which avoids interference between their movement spaces. The moving component is positioned closer to the first end, facilitating connection between the moving component and the transmission component.

[0034] Preferably, the first end forms a receiving space, the receiving space having a first opening, a second opening and a third opening, the first opening and the second opening being used to communicate with the inlet channel or the outlet channel, the connecting channel being formed between the third opening and the second end, and the power component being disposed within the receiving space.

[0035] In this design, the first and second openings are used to allow fluid flow through the fluid system, providing power to the power component. The power component is housed within the containment space, which protects it and prevents damage from the connecting device during transportation or installation. This design also facilitates the standardization of the connecting device, making it compatible with the fluid system.

[0036] A heat exchange device includes a heat exchanger and a fluid system. The fluid system includes an inlet channel, a heat exchange channel, and an outlet channel connected in sequence. The heat exchanger is disposed in the heat exchange channel. The heat exchange device also includes the connecting device described in any of the above technical solutions.

[0037] In this solution, by applying the connection device to the heat exchange equipment, the interlayer of cold water and hot water can be avoided, and the cost is low.

[0038] Preferably, the power component is disposed within the entry channel.

[0039] In this scheme, during the operation of the heat exchange equipment, there are flow losses as the fluid flows from the inlet channel to the outlet channel. The pressure of the fluid in the inlet channel is relatively high. By placing the first end in the inlet channel, the power component is located at the connection between the inlet channel and the connecting channel. This allows the fluid to provide stronger power to the power component, thereby increasing the total potential energy that the potential energy component can store. This results in more power being provided when the potential energy component releases potential energy, thus enabling the fluid to flow more fully and the temperature to be more uniform within the circulation channel formed by the connecting channel, inlet channel, heat exchange channel, and outlet channel.

[0040] The positive and progressive effects of this invention are as follows:

[0041] By isolating the first and second ends when there is fluid flow at the first end, the fluid entering the channel is prevented from entering the delivery channel through the connecting channel, thereby preventing the connecting device from interfering with the normal use of the fluid system; when the fluid stops flowing at the first end, the first and second ends are connected, so that the connecting channel connects the inlet channel and the delivery channel to form a fluid circulation channel, so that when the power component rotates and drives the fluid to flow at the first end, the fluid in the inlet channel, the delivery channel, and the connecting channel can circulate.

[0042] By connecting the moving part and the power part, the rotation of the power part can drive the moving part to move, and the movement of the moving part can drive the rotation of the power part, so as to realize the conversion between linear motion and rotation. This makes it easy for the moving end of the potential energy component to change the distance between itself and the fixed end by moving to store or release potential energy.

[0043] By placing the power component at the first end, located at the junction of the connecting channel and the inlet or outlet channel, the fluid energy provides power to the power component, causing the power component to rotate and the potential energy component to store potential energy. After the fluid stops flowing, the potential energy is released through the potential energy component, causing the power component to rotate to drive the fluid flow. The power source is the fluid, eliminating the need for an additional power source, which reduces costs and eliminates the need to consider the installation of a power source, making the connection device easy to install.

[0044] The connecting device is a mechanical structure, requires no electricity, and is highly reliable.

[0045] By applying connection devices to heat exchange equipment to address the issues of jacketed cold water and jacketed hot water, the cost of heat exchange equipment can be reduced, while its reliability and user experience can be improved. Attached Figure Description

[0058] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0059] It should be noted that "forward" and "backward" are a pair of opposite directions defined for ease of description, and do not refer to a specific direction unless otherwise specified.

[0060] like Figure 1 As shown, the heat exchange device 1 provided in this embodiment is a gas water heater, including a heat exchanger 30, a fluid system, and a connecting device 2. The fluid system includes an inlet channel 25, a heat exchange channel, and an outlet channel 27 connected in sequence. The heat exchanger 30 is located at the heat exchange channel, as shown in the figure. Figure 1 and Figure 2 As shown, the connecting device 2 includes:

[0061] The base 3 has a connecting channel 10 between its first end 4 and second end 9 for fluid flow. The first end 4 is connected to the inlet channel 25 and the second end 9 is connected to the outlet channel 27.

[0062] The power component 17 is rotatably mounted on the first end 4 relative to the base 3;

[0063] The movable component 18 is poweredly connected to the power component 17, so that when the power component 17 rotates, it can drive the movable component 18 to move, and when the movable component 18 moves, it can drive the power component 17 to rotate.

[0064] The potential energy component 21 has a movable end and a fixed end. The movable end is connected to the movable component 18, and the fixed end is connected to the base 3. When the movable end moves with the movable component 18, it changes the distance between itself and the fixed end, thereby playing the role of storing or releasing elastic potential energy.

[0065] like Figure 2 As shown, when there is fluid flowing at the first end 4, the fluid can drive the power component 17 to rotate, causing the moving component 18 to move the moving end in the forward direction to isolate the first end 4 and the second end 9, preventing the fluid entering the channel 25 from entering the delivery channel 27 through the connecting channel 10, thereby preventing the connecting device 2 from interfering with the normal use of the heat exchange equipment 1.

[0066] like Figure 3 As shown, after the fluid at the first end 4 stops flowing, the moving end drives the moving part 18 to move in the opposite direction so that the first end 4 and the second end 9 are connected, so that the connecting channel 10 is connected to the inlet channel 25 and the outlet channel 27 to form a fluid circulation channel. At the same time, the moving part 18 drives the power part 17 to rotate so that the fluid at the first end 4 flows, thereby allowing the fluid in the inlet channel 25, the heat exchange channel and the outlet channel 27 to circulate, avoiding the interlayer cold water and interlayer hot water.

[0067] By placing the power component 17 at the first end 4, the fluid flow within the channel 25 provides power to the power component 17, causing it to rotate and storing potential energy in the potential energy component 21. After the fluid stops flowing, the potential energy is released through the potential energy component 21, causing the power component 17 to rotate and drive the fluid flow. Since the power source is the fluid itself, no additional power source such as a pump is required, resulting in low cost. The installation of power sources such as pumps typically has specific requirements. Because no additional power source is needed, and the installation of the power source is not considered, the connection device 2 is easy to install, and the structure of the heat exchanger 1 is simplified.

[0068] Specifically, such as Figure 1 As shown, heat exchanger 1 also includes:

[0069] Gas distribution system 28, used for distributing gas;

[0070] Combustion chamber 29 is used for burning fuel gas.

[0071] Heat exchanger 30 is used for heat exchange between the flue gas generated in the heat exchange channel and the combustion chamber 29;

[0072] Smoke hood 31, used to collect smoke;

[0073] Blower 33 is used to blow air and provide air for combustion of the gas;

[0074] Controller 32 is used to control the intake of gas and the blowing of fan 33;

[0075] Air inlet 34 is used to connect with the gas pipeline to supply gas to the heat exchanger 1;

[0076] Inlet 35 is used to connect to the tap water pipe, and the water supply flows into the heat exchange equipment 1;

[0077] Outlet 36 is used to connect to the water valve at the user's end to provide hot water to the user.

[0078] In this embodiment, the fluid is water, the fluid system is a water system, and the heat exchange device 1 is a gas water heater. In other embodiments, the fluid can be liquid or gaseous. When the fluid is liquid, the heat exchange device 1 can be a water heater or other device with a heat exchanger 30 and heat exchange function. The water heater can be a gas water heater, an electric water heater, etc. For example, an electric water heater with a rapid heating function. The heat exchanger 30 is used to heat the water flow in the pipe, not to heat the water in the insulated tank. When the fluid is gaseous, the heat exchange device 1 can be a warm air device or other device with a heat exchanger 30 and heat exchange function.

[0079] In other embodiments, the connecting device 2 can also be used in other devices with fluid systems to circulate the fluid within the fluid system when the fluid system is not in use, in order to prevent the deposition of substances in the fluid.

[0080] Furthermore, the first end 4 serves as part of the inlet channel 25, and the first end 4 forms a receiving space 5. The receiving space 5 has a first opening 6, a second opening 7, and a third opening 8. The first opening 6 and the second opening 7 are used to communicate with the inlet channel 25 to allow normal flow of fluid within the inlet channel 25. The connecting channel 10 is formed between the third opening 8 and the second end 9. The power component 17 is disposed within the receiving space 5, which can protect the power component 17 and prevent damage to the power component 17 during transportation or installation. It also facilitates the standardization of the connecting device 2 to adapt to the fluid system by defining the size standards of the first opening 6, the second opening 7, etc.

[0081] During operation, the fluid system experiences flow losses as it flows from the inlet channel 25 to the outlet channel 27, resulting in higher pressure within the inlet channel 25. In this embodiment, the first end 4 is positioned corresponding to the inlet channel 25, which strengthens the power provided by the fluid flow to the power unit 17, thereby increasing the total potential energy stored in the potential energy unit 21 and providing more power when it releases potential energy. When the connecting device 2 is used in the heat exchanger 1, it allows for more complete fluid flow within the circulation channel formed by the connecting channel 10, inlet channel 25, heat exchange channel, and outlet channel 27, resulting in a more uniform temperature and further improving the effectiveness of the jacketed cold and hot water systems. In this embodiment, the power unit 17 is positioned within the inlet channel 25, further increasing the power provided by the fluid to it.

[0082] In other embodiments, the first end 4 may be configured to correspond to the output channel 27, and the second end 9 may be configured to correspond to the input channel 25. In other embodiments, the first end 4 may not be part of the input channel 25 or the output channel 27, and the receiving space 5 and the input channel 25 or the output channel 27 may be connected in parallel through the first opening 6 and the second opening 7. In other embodiments, the first end 4 may not form the receiving space 5, the first opening 6, and the second opening 7, and may be connected to the input channel 25 or the output channel 27 through the third opening 8.

[0083] Furthermore, such as Figure 2 As shown, the connecting device 2 also includes a transmission component 19, a power component 17, and a moving component 18 connected in sequence. By setting the transmission component 19 to connect the power component 17 and the moving component 18, the installation requirements of the power component 17 and the moving component 18 can be reduced. It is convenient for the power component 17 to be set at the connection between the connecting channel 10 and the entry channel 25, and it is convenient for the moving component 18 to move to isolate or connect the first end 4 and the second end 9.

[0084] Specifically, the transmission component 19 and the power component 17 are fixedly connected and are also poweredly connected, so that when the power component 17 rotates, it drives the transmission component 19 to rotate, thereby driving the moving component 18 to move, and when the moving component 18 moves, it drives the transmission component 19 to rotate, thereby driving the power component 17 to rotate.

[0085] In this embodiment, the power component 17 is a rotating blade assembly. When fluid flows through the rotating blade assembly, there are gaps between the blades to allow fluid to pass through. When the fluid flows through the blades, the fluid pressure acts on the blades, thereby driving the rotating blade assembly to rotate. The transmission component 19 is a rack, and the moving component 18 is a gear. The rotating blades and the rack are fixedly connected, and the rack and gear mesh with each other. The gear is fixedly connected to the moving end of the potential energy component 21, thereby forming an indirect connection between the gear and the base 3. When the rack rotates relative to the base 3, it can drive the gear to move relative to the base 3. When the gear moves relative to the base 3, it can drive the rack to rotate relative to the base 3. The structure is simple and the transmission is reliable. Furthermore, there are two racks, and the gear is placed between the two racks to improve stability.

[0086] In other embodiments, the transmission component 19 and the moving component 18 can employ mechanisms that convert between rotary and linear motion, such as gear and rack mechanisms, nut and screw mechanisms, or cam mechanisms. In other embodiments, the transmission component 19 and the power component 17 may not be fixedly connected; for example, the transmission component 19 can be a gear, and the power component 17 can be equipped with a gear that meshes with it. In other embodiments, the transmission component 19 can be a moving component, with the moving component 18 driving the transmission component 19 to move, and the movement of the transmission component 19 driving the power component 17 to rotate. The transmission component 19 and the power component 17 employ a mechanism that converts between rotary and linear motion. In other embodiments, the transmission component 19 may be omitted, and the power component 17 and the moving component 18 can directly form a mechanism that converts between rotary and linear motion. For example, the power component 17 may be machined with an internal thread, and the moving component 18 may be a screw, with the screw meshing with the internal thread. The shape of the relevant channels can be adaptively adjusted to provide movement space for the screw; or, the power component 17 may be equipped with an external thread, and the moving component 18 may be a nut, with the external thread meshing with the nut.

[0087] Furthermore, such as Figure 2 As shown, the wall of the connecting channel 10 is formed with a narrow opening 11 that connects the first end 4 and the second end 9. When the moving member 18 moves forward, it moves closer to the narrow opening 11 to block the narrow opening 11. When the moving member 18 moves in the reverse direction, it moves away from the narrow opening 11 to open the narrow opening 11.

[0088] Furthermore, such as Figure 2As shown, the connecting device 2 also includes a plug 20, which is connected to the movable part 18. The shape of the plug 20 matches the shape of the narrow opening 11 to separate the first end 4 and the second end 9, reducing the requirements for the shape and size of the movable part 18 and facilitating the processing and installation of the movable part 18.

[0089] like Figure 2 As shown, the narrow opening 11 is funnel-shaped, allowing it to open only in one direction. When the fluid system is operating and the moving part 18 moves in the forward direction, it prevents the connecting channel 10 from connecting at the narrow opening 11, thus improving the reliability of the connecting device 2. Furthermore, the opening of the narrow opening 11 faces the first end 4, and the plug 20 is positioned between the first end 4 and the narrow opening 11. When the connecting device 2 is connected to the fluid system, and the first end 4 is used to connect to the inlet channel 25, the fluid tends to flow from the first end 4 to the narrow opening 11. The fluid pressure acting on the plug 20 also facilitates the plug 20 in sealing the narrow opening 11.

[0090] In other embodiments, the narrow opening 11 can be flared regardless of whether the plug 20 is provided. In other embodiments, the narrow opening 11 can be flange-shaped, or have a shape that reduces the diameter of the connecting channel 10. In other embodiments, when the plug 20 is not provided, the shape of the movable member 18 can be configured to match the shape of the narrow opening 11 to seal it. In other embodiments, the narrow opening 11 may not be provided; for example, the base 3 can be... Figure 4 The structure shown has at least a portion of the inner base 41 of the base 3 disposed inside the outer base 42, and a connecting hole 411 is formed on the wall of the portion of the inner base 41 located inside the outer base 42, so that the first end 4 and the second end 9 are connected. Correspondingly, a movable member 18 or a plug 20 is disposed inside the inner base 41 and matches the shape of the inner base 41, so that the movable member 18 or the plug 20 can move to block the connecting hole 411 to isolate the first end 4 and the second end 9. Figure 4 The dashed line represents a fluid connection path. The direction of the arrow on the dashed line is only for illustrative purposes and does not specify the direction of fluid flow.

[0091] Furthermore, such as Figure 2As shown, the potential energy component 21 includes a first potential energy component 22 and a second potential energy component 23. One end of the first potential energy component 22 is a fixed end connected to the base 3, and the other end is connected to the plug 20. One end of the second potential energy component 23 is connected to the plug 20, and the other end is a movable end connected to the movable component 18. When the plug 20 and the movable component 18 are indirectly connected through the second potential energy component 23, on the one hand, the positional requirements of the plug 20 and the movable component 18 can be reduced, making it easier to set up the plug 20 and the movable component 18; on the other hand, interference between the plug 20 and the transmission component 19 can be avoided. In other embodiments, the second potential energy component 23 may not be provided, and the plug 20 or the first potential energy component 22 may be directly connected to the movable component 18. The end of the first potential energy component 22 connected to the base 3 is a fixed end, and the end connected to the plug 20 or the movable component 18 is a movable end.

[0092] Specifically, in this embodiment, both the first potential energy element 22 and the second potential energy element 23 are elastic elements, which have a simple structure and low cost. In other embodiments, the potential energy element 21 can be used to store and release elastic potential energy and / or magnetic potential energy. When the potential energy element 21 is used to store and release magnetic potential energy, the fixed end and the moving end are separate. The fixed end is fixed to the base 3, and the moving end is connected to the moving member 18 and moves with the moving member 18. The fixed end and the moving end move closer to or further away from each other to store or release elastic potential energy. In other embodiments, both the first potential energy element 22 and the second potential energy element 23 can be magnetic elements; or one of the first potential energy element 22 and the second potential energy element 23 can be an elastic element and the other a magnetic element.

[0093] like Figure 2 As shown, the base 3 includes a first base 13 and a second base 14 fixedly connected. A first flange 15 and a second flange 16 are formed on the second base 14. A third opening 8 is formed within the first flange 15 to facilitate the installation of the transmission component 19. The second flange 16 facilitates the connection between the fixed end of the potential energy component 21 and the second base 14. The first base 13 and the second base 14 together form a receiving space 5, allowing the first base 13 to be installed on the second base 14 after the transmission component 19 and the second base 14 are installed, thus facilitating installation. Furthermore, the first base 13 and the second base 14 can be detachably connected by threads or welded together to form a non-detachable connection. When the first end 4 does not have the receiving space 5, the first opening 6, or the second opening 7, the first base 13 may be omitted.

[0094] like Figure 2 As shown, a groove is formed at the plug 20 to install the second potential energy element 23, and a groove is formed at the second flange 16 to install the first potential energy element 22. By constraining the movement direction of the potential energy element 21 through the grooves at the plug 20 and the second flange 16, the stability and reliability of the adjustment device can be improved.

[0095] like Figure 2As shown, from the first end 4 to the second end 9, the moving part 18 and the potential energy part 21 are arranged in sequence, so that the moving part 18 and the potential energy part 21 are arranged in series, which can avoid interference between the moving part 18 and the potential energy part 21 in their movement space. The moving part 18 is set closer to the first end 4, which facilitates the connection between the moving part 18 and the transmission part 19. Specifically, from the first end 4 to the second end 9, the moving part 18, the first potential energy part 22, the plug 20, and the second potential energy part 23 are arranged in sequence, which facilitates the placement of the power part 17, the transmission part 19, the moving part 18, and the plug 20 at one end of the narrow opening 11, and the fixed end of the first potential energy part 22 at the other end of the narrow opening 11.

[0096] In other embodiments, the potential energy element 21 and the moving element 18 can be arranged in parallel. For example, the potential energy element 21 is a magnetic element, with one end fixed to the moving element 18 as the moving end and the other end fixed between the narrow opening 11 and the first end 4 as the fixed end. The moving end and the fixed end attract each other. When the moving element 18 drives the moving end to move forward, the moving end moves away from the fixed end to store potential energy. When the moving end releases potential energy, it moves closer to the fixed end to release potential energy and drive the moving element 18 to move in the opposite direction.

[0097] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
