Description

Technical Field

[0001] This utility model relates to the field of chainsaw technology, and more specifically, to a chainsaw. Background Technology

[0002] In existing technology, the design of the oil pumping system and oil pipes in chainsaws has certain flaws. During operation, the oil pumping system is responsible for delivering lubricating oil from the oil tank to the saw chain and guide plate through the oil pipes to ensure their normal operation. However, when the chainsaw stops working, the oil pumping system also shuts down, and the lubricating oil remaining in the oil pipes is not promptly returned to the oil tank. Due to the influence of external environmental temperature changes on the oil pressure within the oil pipes, especially under thermal expansion and contraction, the pressure changes within the oil pipes may cause lubricating oil to overflow.

[0003] Lubricating oil spills not only contaminate the chainsaw's casing but can also cause environmental pollution if accidentally dripped onto the floor or shelves when the machine is cleaned or stored. This pollution is not only unsightly but also difficult to clean, causing inconvenience to users. Furthermore, lubricating oil spills represent a waste of resources, contradicting the principles of resource conservation and environmental protection. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a chainsaw with an oil supply system that can recover the oil in the oil pipe to the oil tank after the chainsaw stops working, which solves the problem that the lubricating oil remaining in the oil pipe may overflow when the chainsaw stops working in the prior art.

[0005] To achieve the above objectives, the technical solution provided by an embodiment of this utility model is as follows:

[0006] A chainsaw includes an oil supply system comprising: an oil tank for storing oil, the oil tank including an oil outlet and an oil inlet; an oil outlet pipe, a first end of which is connected to the oil outlet; an oil supply pipe, a first end of which is disposed toward the part to be lubricated; and an oil pump assembly including a pump body inlet and a pump body outlet, the pump body inlet being connected to a second end of the oil outlet pipe, and the pump body outlet being connected to a second end of the oil supply pipe; wherein the oil pump assembly can switch between a forward and reverse rotation state to draw oil from the oil tank through the oil outlet pipe and supply oil to the part to be lubricated through the oil supply pipe, or to draw oil from the oil supply pipe and return it to the oil tank through the oil outlet pipe.

[0007] Furthermore, the oil supply system also includes a main controller, which is electrically connected to the oil pump assembly to control the oil pump assembly to be in a forward or reverse rotation state. Based on modern electronic control technology, the main controller uses circuits and algorithms to control the forward or reverse rotation of the oil pump assembly, achieving automatic oil supply and recovery. This improves the automation level of the oil supply system, simplifies the operation process, and enhances the system's stability and reliability.

[0008] Furthermore, the oil supply system also includes an oil level monitoring device. This device is installed on the oil outlet pipe and electrically connected to the main controller to monitor whether the outlet pipe contains oil and to feed the monitoring results back to the main controller. The oil level monitoring device uses sensor technology to monitor the oil level in the outlet pipe and transmits the signal to the main controller, enabling real-time monitoring of the oil supply. This improves the intelligence level of the oil supply system, allows for timely adjustments to the oil supply strategy, avoids oil waste and poor equipment lubrication, enhances the user experience, and ensures the thoroughness and accuracy of lubricant recovery.

[0009] Furthermore, the oil quantity monitoring device includes at least one of capacitive sensors, ultrasonic sensors, and optical sensors. Depending on the specific application environment and requirements, one or more of these sensors can be selected to achieve comprehensive monitoring of the oil condition, thereby improving the accuracy and adaptability of oil quantity monitoring.

[0010] Furthermore, the oil quantity monitoring device includes a transmitter and a receiver, which are spaced apart and arranged opposite each other along a direction perpendicular to the extension direction of the oil outlet pipe. The receiver is used to receive at least a portion of the light emitted by the transmitter, so as to determine whether there is oil inside the oil pipe based on the change in the intensity of the light received by the receiver. This improves the sensitivity and accuracy of oil quantity monitoring, enables real-time monitoring of oil status, ensures the rationality of oil supply, and improves the operating efficiency and maintenance level of the equipment.

[0011] Furthermore, the oil supply system also includes a user prompting device, which is electrically connected to the main controller. When the main controller receives the monitoring results, it sends a prompting command to the user prompting device to issue a prompt message indicating that oil recovery is complete. This improves the user's awareness of the oil supply system and the ease of operation, allowing the user to understand the oil recovery status in a timely manner, facilitating subsequent operation and maintenance, and enhancing the user-friendliness and operational safety of the equipment.

[0012] Furthermore, the user prompting device includes: a light prompting component for emitting a prompting light; and / or a voice prompting component for emitting a prompting voice, which improves the user's awareness of the oil supply system and the ease of operation, enabling the user to immediately notice the oil recovery status and take appropriate measures in a timely manner.

[0013] Furthermore, the oil outlet pipe includes a pipe body and a filter component. The filter component is located at the end of the pipe body near the pump inlet to filter impurities in the oil, ensuring the purity of the oil, improving the stability and reliability of the oil supply system, avoiding damage to the pump components and lubricated parts by impurities, protecting the equipment from contamination, and extending the service life of the equipment.

[0014] Furthermore, the filter component includes a filter spring, which comprises a conical spring segment and a cylindrical spring segment connected together. The outer diameter of the conical spring segment gradually decreases in the direction away from the cylindrical spring segment. The cylindrical spring segment is used to fit onto the pipe body, with the conical spring segment located at the end of the cylindrical spring segment away from the pipe body. Utilizing the elastic deformation characteristics of a spring, the filter component forms a spring knot with filtering function through the combination of the conical and cylindrical spring segments. This improves the filtration efficiency and self-cleaning ability of the filter component, enabling continuous and efficient filtration of impurities in the oil, protecting the equipment from contamination, and improving the equipment's operating efficiency and maintenance cycle.

[0015] A chainsaw includes: a chainsaw assembly; and an oil supply system including: an oil tank for storing oil, the oil tank including an oil outlet and an oil inlet; an oil outlet pipe, a first end of which is connected to the oil outlet; an oil supply pipe, a first end of which is disposed toward the part to be lubricated; and an oil pump assembly including a pump body inlet and a pump body outlet, the pump body inlet being connected to a second end of the oil outlet pipe, and the pump body outlet being connected to a second end of the oil supply pipe; wherein the oil pump assembly can switch between a forward and reverse rotation state, and the first end of the oil supply pipe is disposed toward the part to be lubricated in the chainsaw assembly; when the chainsaw assembly is working, the oil pump assembly draws oil from the oil tank into the oil supply pipe for supplying oil to the part to be lubricated; or when the chainsaw assembly stops working, the oil pump assembly draws oil from the oil supply pipe back into the oil tank. The oil supply system of this application can automatically adjust the oil flow direction at different stages of chainsaw operation and shutdown. Combined with intelligent monitoring and user prompt functions, it not only solves the problem of lubricating oil leakage caused by temperature changes in chainsaws and other equipment, improving the lubrication effect, but also greatly enhances the operability and maintainability of chainsaws.

[0016] This utility model has the following beneficial effects: The oil supply system of this utility model includes: an oil tank for storing oil, the oil tank including an oil outlet and an oil inlet; an oil outlet pipe, the first end of the oil outlet pipe being connected to the oil outlet; an oil supply pipe, the first end of the oil supply pipe being positioned towards the part to be lubricated; and an oil pump assembly, the oil pump assembly including a pump body inlet and a pump body outlet, the pump body inlet being connected to the second end of the oil outlet pipe, and the pump body outlet being connected to the second end of the oil supply pipe; wherein, the oil pump assembly can switch between a forward rotation state and a reverse rotation state to draw oil from the oil tank through the oil outlet pipe and supply it to the part to be lubricated through the oil supply pipe, or to draw oil from the oil supply pipe and return it to the oil tank through the oil outlet pipe. In this way, the oil supply system of this application, through the forward and reverse rotation function of the oil pump assembly, can effectively recover the residual lubricating oil in the oil supply pipe to the oil tank after the chainsaw stops working. This solves the problem that the residual lubricating oil in the oil pipe may overflow when the chainsaw stops working in the prior art. It avoids the lubricating oil remaining in the oil pipe from overflowing due to thermal expansion and contraction, thereby protecting the cleanliness of the chainsaw and the storage environment such as the storage room floor and shelves, reducing the waste of lubricating oil, and achieving resource conservation.

[0053] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0054] To address the problems of low curling efficiency and lack of volume in existing hair curling attachments, this invention provides an oil supply system and a chainsaw. The oil supply system includes...

[0055] To achieve the above objectives, the technical solution provided by an embodiment of this utility model is as follows:

[0056] like Figures 1 to 19As shown, this utility model provides a chainsaw, including an oil supply system. The system includes: an oil tank 1 for storing oil, the oil tank 1 including an oil outlet and an oil inlet; an oil outlet pipe 2, the first end of the oil outlet pipe 2 being connected to the oil outlet; an oil supply pipe 3, the first end of the oil supply pipe 3 being positioned towards the part to be lubricated; and an oil pump assembly 4, the oil pump assembly 4 including a pump body inlet and a pump body outlet, the pump body inlet being connected to the second end of the oil outlet pipe 2, and the pump body outlet being connected to the second end of the oil supply pipe 3. The oil pump assembly 4 can switch between a forward rotation state and a reverse rotation state to draw oil from the oil tank 1 through the oil outlet pipe 2 and supply it to the part to be lubricated through the oil supply pipe 3, or to draw oil from the oil supply pipe 3 and return it to the oil tank 1 through the oil outlet pipe 2.

[0057] In this way, the oil supply system of this application, through the forward and reverse rotation function of the oil pump assembly 4, can effectively recover the residual lubricating oil in the oil supply pipe 3 to the oil tank 1 after the chainsaw stops working. This solves the problem that the residual lubricating oil in the oil pipe may overflow when the chainsaw stops working in the prior art. It avoids the phenomenon of lubricating oil overflow caused by thermal expansion and contraction due to the residual lubricating oil in the oil pipe, thereby protecting the cleanliness of the chainsaw and the storage environment such as the storage room floor and shelves, reducing the waste of lubricating oil, and realizing resource conservation.

[0058] Oil tank 1, as the core component of the oil supply system, includes an oil outlet and an oil inlet. Based on the basic concept of container storage, it can stably store lubricating oil and manage the inflow and outflow of oil through the oil outlet and oil inlet, ensuring the normal operation of the oil supply system and ensuring that sufficient oil is provided when the chainsaw is working to meet the lubrication needs of the chainsaw.

[0059] The first end of the oil outlet pipe 2 is connected to the oil outlet, and the second end of the oil outlet pipe 2 is connected to the pump inlet; so as to transfer the oil in the oil tank 1 to the pump assembly 4. By utilizing the transport characteristics of the pipeline, it ensures the smooth flow of oil from the oil tank 1 to the pump assembly 4, ensuring the efficiency of oil transfer and reducing oil loss during the transfer process.

[0060] The first end of the oil supply pipe 3 is set towards the part to be lubricated, and the second end of the oil supply pipe 3 is connected to the pump outlet. It can accurately deliver oil to the part to be lubricated according to the position of the lubrication point on the part to be lubricated and the oil flow path, so as to achieve the lubrication effect, improve the accuracy and efficiency of lubrication, reduce the risk of insufficient or excessive lubrication, extend the service life of the chainsaw, and improve the working efficiency of the chainsaw.

[0061] The oil pump assembly 4 includes a pump body inlet and a pump body outlet. The pump body inlet is connected to the second end of the oil outlet pipe 2, and the pump body outlet is connected to the second end of the oil supply pipe 3. The rotational force of the oil pump motor in the oil pump assembly 4 drives the pump body to rotate, thereby generating the power for oil suction and discharge, realizing the directional delivery of oil, improving the power and stability of oil delivery, ensuring the continuity and reliability of oil supply, and ensuring that the chainsaw can be fully lubricated under different working conditions.

[0062] The oil pump assembly 4 includes a pump body and an oil pump motor that drives at least part of the pump body to rotate. The oil pump motor can be switched between forward and reverse rotation. When the chainsaw is working normally, the oil pump motor rotates forward to draw oil from the oil tank 1 through the oil outlet pipe 2 and supply oil to the parts to be lubricated through the oil supply pipe 3. When the chainsaw stops working, the oil pump motor rotates in reverse to draw oil from the oil supply pipe 3 and send it back to the oil tank 1 through the oil outlet pipe 2. The forward and reverse rotation functions of the oil pump assembly 4 utilize the bidirectional rotation characteristics of the oil pump motor to achieve bidirectional flow of oil. That is, when rotating forward, oil is delivered from the oil tank 1 to the parts to be lubricated, and when rotating in reverse, oil is recovered from the oil supply pipe 3 to the oil tank 1. This significantly improves the flexibility and intelligence of the oil supply system. In particular, after the chainsaw stops, it can automatically recover the residual lubricating oil in the pipe, avoiding environmental pollution and resource waste, and maintaining the cleanliness and environmental friendliness of the chainsaw.

[0063] like Figure 17 As shown, the oil supply system of this utility model also includes a main controller 5, which is electrically connected to the oil pump assembly 4 to control the oil pump assembly 4 to be in a forward or reverse rotation state. Based on modern electronic control technology, the main controller 5 controls the forward or reverse rotation of the oil pump assembly 4 through circuits and algorithms, realizing automatic oil supply and recovery, improving the automation level of the oil supply system, simplifying the operation process, and enhancing the stability and reliability of the system. In various mechanical equipment requiring oil lubrication, the main controller 5 can intelligently adjust the oil supply and recovery strategy according to the working status of the equipment and environmental conditions, making it suitable for equipment lubrication management in various complex environments such as industrial production and outdoor operations.

[0064] like Figures 8 to 11As shown, the oil supply system of this utility model also includes an oil quantity monitoring device 6. The oil quantity monitoring device 6 is installed on the oil outlet pipe 2 and electrically connected to the main controller 5 to monitor whether the oil outlet pipe 2 contains oil and to feed the monitoring results back to the main controller 5. The oil quantity monitoring device 6 uses sensor technology to monitor the oil quantity in the oil outlet pipe 2 and transmits the signal to the main controller 5, realizing real-time monitoring of the oil supply. This improves the intelligence level of the oil supply system, enables timely adjustment of the oil supply strategy, avoids oil waste and poor equipment lubrication, improves user experience, and ensures the thoroughness and accuracy of lubricant recovery. When the oil quantity monitoring device 6 is applied to mechanical equipment requiring precise control of oil supply, such as chainsaws and precision machine tools, it can ensure timely oil supply and recovery, improving equipment operating efficiency and maintenance levels.

[0065] Optionally, the oil quantity monitoring device 6 includes at least one of a capacitive sensor, an ultrasonic sensor, and an optical sensor. The design principle of the capacitive sensor, ultrasonic sensor, and optical sensor is based on different physical principles (such as capacitance change, sound wave reflection, or light signal change) to monitor the oil state in the oil pipe 2. Depending on the specific application environment and requirements, one or more of the capacitive sensor, ultrasonic sensor, and optical sensor can be selected to achieve comprehensive monitoring of the oil state, thereby improving the accuracy and adaptability of oil quantity monitoring.

[0066] In such Figure 8 and Figure 9 In the first embodiment shown, the oil outlet pipe 2 is provided with a mounting hole for installing an oil quantity monitoring device 6. The oil quantity monitoring device 6 includes a base 61, a lens 62, a transmitter 63, and a receiver 64. The base 61 is inserted into the mounting hole. The lens 62 is located on the side of the base 61 closer to the inside of the oil outlet pipe 2 and is connected to the base 61. The transmitter 63 and the receiver 64 are spaced apart between the base 61 and the lens 62 along the extension direction of the oil outlet pipe 2, and both the transmitter 63 and the receiver 64 are facing the lens 62. The lens 62 is used to reflect at least a portion of the light emitted by the transmitter 63 to the receiver 64, so as to determine whether there is oil inside the oil outlet pipe 2 based on the change in the intensity of the light received by the receiver 64. The oil level monitoring device 6 is based on the principle of lens reflection. It uses lens 62 to reflect the light emitted by the transmitter 63 to the receiver 64. By monitoring the change in the intensity of the light received by the receiver 64, it can determine whether there is oil inside the oil pipe 2. This improves the sensitivity and accuracy of oil level monitoring, enables real-time monitoring of oil status, ensures the rationality of oil supply, and improves the operating efficiency and maintenance level of the equipment.

[0067] like Figure 8 and Figure 9As shown, lens 62 includes a first lens surface and a second lens surface connected together. The angle between the first lens surface and the second lens surface is an acute angle. When the light emitted from the emitting end 63 reaches the first lens surface, it can be reflected by the first lens surface to the second lens surface, and then reflected by the second lens surface to the receiving end 64 for reception. When there is oil inside the oil outlet pipe 2, the light reaching the first lens surface can be refracted in the oil after passing through the first lens surface.

[0068] The emitting end 63 includes a light-emitting diode.

[0069] Specifically, such as Figure 8 As shown, when there is no oil in the oil outlet pipe 2, most of the light emitted from the transmitter 63 will pass through the lens 62 and reach the receiver 64; Figure 9 As shown, when there is oil in the oil outlet pipe 2, most of the light emitted by the transmitter 63 will pass through the lens 62 and be refracted in the oil. Only a small portion can pass through the lens 62 and reach the receiver 64.

[0070] In such Figure 10 and Figure 11 In the second embodiment shown, the oil level monitoring device 6 includes a transmitter 63 and a receiver 64. The transmitter 63 and receiver 64 are spaced apart and arranged opposite each other along a direction perpendicular to the extension direction of the oil outlet pipe 2. The receiver 64 is used to receive at least a portion of the light emitted by the transmitter 63, so as to determine whether there is oil inside the oil outlet pipe 2 based on the change in the intensity of the light received by the receiver 64. The oil level monitoring device 6 adopts the principle of transmission and reception. The light emitted by the transmitter 63 passes through the internal space of the oil outlet pipe 2 and is received by the receiver 64. By monitoring the change in the intensity of the light, it is determined whether there is oil inside the oil outlet pipe 2, which improves the response speed and accuracy of oil level monitoring, and can capture the change in oil state instantly, thereby improving the safety and stability of the equipment.

[0071] The emitting end 63 includes a light-emitting diode.

[0072] Specifically, such as Figure 10 As shown, when there is no oil in the oil outlet pipe 2, most of the light emitted by the transmitter 63 will directly reach the receiver 64; Figure 11 As shown, when there is oil in the oil outlet pipe 2, most of the light emitted by the transmitter 63 will be refracted by the oil, and only a small portion will reach the receiver 64.

[0073] The oil supply system of this utility model also includes a user prompting device 7, which is electrically connected to the main controller 5. When the main controller 5 receives the monitoring results, it sends a prompting command to the user prompting device 7 to control the user prompting device 7 to issue a prompt message indicating that oil recovery is complete. The design principle of the user prompting device 7 is based on human-computer interaction technology. Through the signal output of the main controller 5, such as through visual or auditory signals, it provides users with information feedback on the oil recovery status, improving the user's perception of the oil supply system and the ease of operation. This allows users to understand the oil recovery status in a timely manner, facilitating subsequent operation and maintenance, and improving the user-friendliness and operational safety of the equipment.

[0074] Optionally, the user prompting device 7 includes: a light prompting component for emitting a prompt light; and / or a voice prompting component for emitting a prompt voice. The design principle of the light prompting component and the voice prompting component is to use a signal generator to produce visual or auditory signals, providing the user with intuitive feedback on the oil recovery status. This improves the user's perception of the oil supply system and the ease of operation, enabling the user to immediately notice the oil recovery status and take timely appropriate measures. When the oil supply system of this invention is applied to various mechanical equipment requiring user attention, such as chainsaws and automobile engines, the light prompting component and the voice prompting component can remind the user that oil recovery is complete through flashing lights or voice announcements.

[0075] like Figure 13 and Figure 14 As shown, the oil outlet pipe 2 includes a pipe body 21 and a filter component 22. The filter component 22 is located at the end of the pipe body 21 near the pump inlet to filter impurities in the oil. By intercepting impurities in the oil through the filter component 22, the purity of the oil is ensured, the stability and reliability of the oil supply system are improved, impurities are prevented from damaging the pump oil assembly 4 and the parts to be lubricated, the equipment is protected from contamination, and the service life of the equipment is extended.

[0076] Specifically, the filter component 22 includes a filter spring, which comprises a conical spring segment 221 and a cylindrical spring segment 222 connected together. The outer diameter of the conical spring segment 221 gradually decreases in the direction away from the cylindrical spring segment 222. The cylindrical spring segment 222 is used to be sleeved on the pipe body 21, and the conical spring segment 221 is located at the end of the cylindrical spring segment 222 away from the pipe body 21. The filter component 22 utilizes the elastic deformation characteristics of the spring to form a spring knot with filtering function through the combination of the conical spring segment 221 and the cylindrical spring segment 222, which improves the filtration efficiency and self-cleaning ability of the filter component 22. It can continuously and efficiently filter impurities in the oil, protect the equipment from contamination, and improve the operating efficiency and maintenance cycle of the equipment.

[0077] This utility model also includes a chainsaw, comprising: a chainsaw assembly 8; an oil supply system, comprising: an oil tank 1 for storing oil, the oil tank 1 including an oil outlet and an oil inlet; an oil outlet pipe 2, the first end of the oil outlet pipe 2 being connected to the oil outlet; an oil supply pipe 3, the first end of the oil supply pipe 3 being positioned towards the component to be lubricated; and an oil pump assembly 4, the oil pump assembly 4 including a pump body inlet and a pump body outlet, the pump body inlet being connected to the second end of the oil outlet pipe 2, and the pump body outlet being connected to the second end of the oil supply pipe 3; wherein, the oil pump assembly 4 can switch between a forward rotation state and a reverse rotation state, and the first end of the oil supply pipe 3 is positioned towards the component to be lubricated in the chainsaw assembly 8; when the chainsaw assembly 8 is working, the oil pump assembly 4 draws the oil from the oil tank 1 into the oil supply pipe 3 for supplying oil to the component to be lubricated; or when the chainsaw assembly 8 stops working, the oil pump assembly 4 draws the oil from the oil supply pipe 3 back into the oil tank 1.

[0078] In this way, the oil supply system of this application can automatically adjust the oil flow direction at different stages of chainsaw operation and shutdown. Combined with intelligent monitoring and user prompt functions, it not only solves the problem of lubricating oil leakage caused by temperature changes in chainsaws and other equipment, and improves the lubrication effect, but also greatly enhances the operability and maintainability of chainsaws.

[0079] Specifically, the chainsaw assembly 8 includes a chainsaw body and a guide plate. The guide plate is provided with a lubricating oil channel. The component to be lubricated includes the guide plate. The first end of the oil supply pipe 3 is connected to the lubricating oil channel on the guide plate to supply oil to the lubricating oil channel.

[0080] The working process of the oil supply system of this utility model is as follows:

[0081] (1) When the chainsaw is finished, the main controller 5 starts timing. When the chainsaw stops for a certain period of time (e.g., 5 min to 30 min), the main controller 5 controls the oil pump assembly 4 to be in reverse for a period of time (3 s to 10 s) to draw the lubricating oil in the oil supply pipe 3 back into the oil tank 1.

[0082] (2) When the main controller 5 controls the main controller 5 to be in reverse state, it can simultaneously control the oil quantity monitoring device 6 to monitor the oil quantity in the oil outlet pipe 2, and finally feed back to the user through the main controller 5 and the user prompt device 7 a prompt that "the lubricating oil in the pipe has been recovered" (such as light or voice prompt).

[0083] This utility model has at least the following beneficial effects:

[0084] The oil supply system of this utility model includes: an oil tank 1 for storing oil, the oil tank 1 including an oil outlet and an oil inlet; an oil outlet pipe 2, the first end of the oil outlet pipe 2 being connected to the oil outlet; an oil supply pipe 3, the first end of the oil supply pipe 3 being positioned towards the component to be lubricated; and an oil pump assembly 4, the oil pump assembly 4 including a pump body inlet and a pump body outlet, the pump body inlet being connected to the second end of the oil outlet pipe 2, and the pump body outlet being connected to the second end of the oil supply pipe 3; wherein, the oil pump assembly 4 can switch between a forward rotation state and a reverse rotation state to draw oil from the oil tank 1 through the oil outlet pipe 2 and supply it to the component to be lubricated through the oil supply pipe 3, or to draw oil from the oil supply pipe 3 and return it to the oil tank 1 through the oil outlet pipe 2. In this way, the oil supply system of this application, through the forward and reverse rotation function of the oil pump assembly 4, can effectively recover the residual lubricating oil in the oil supply pipe 3 to the oil tank 1 after the chainsaw stops working. This solves the problem that the residual lubricating oil in the oil pipe may overflow when the chainsaw stops working in the prior art. It avoids the phenomenon of lubricating oil overflow caused by thermal expansion and contraction due to the residual lubricating oil in the oil pipe, thereby protecting the cleanliness of the chainsaw and the storage environment such as the storage room floor and shelves, reducing the waste of lubricating oil, and realizing resource conservation.
