[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0055] This application provides a drainage assembly 10; please refer to [link / reference]. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the drainage assembly (with the drainage hole in a sealed state) provided in an exemplary embodiment of this disclosure. Figure 2 This is a schematic diagram of the structure of a drainage assembly (drainage hole in the open state) provided in an exemplary embodiment of this disclosure. The drainage assembly 10 includes a housing 1 and a plug assembly.

[0056] The housing 1 has a water inlet 11 and a drain 12. The water inlet 11 is used to connect to the condenser section 20 of the air compressor, so that the condensate output from the condenser section 20 can enter the housing 1 through the water inlet 11.

[0057] It should be noted that the water inlet 11 and the drain 12 can be arranged at intervals along the direction of gravity, and the drain 12 is located below the water inlet 11. Furthermore, this application does not limit the shape or specific location of the water inlet 11 and the drain 12. For example, the water inlet 11 can be located on the side or top of the housing 1. The drain 12 can be located on the side or bottom of the housing 1.

[0058] The plug assembly is located inside the housing 1. The plug assembly includes a first plug 21 and a second plug 22. The first plug 21 is used to seal the water inlet hole 11, and the second plug 22 is used to seal the drain hole 12. The plug assembly is configured such that when the second plug 22 opens the drain hole 12, the first plug 21 seals the water inlet hole 11.

[0059] It should be noted that, in order to improve the sealing performance of the first plug 21 and the second plug 22, the materials used to make the first plug 21 and the second plug 22 have a certain degree of elasticity. Because elastic materials can adaptively adjust their shape according to changes in external or internal pressure, when the first plug 21 is pressed against the water inlet 11 and the second plug 22 is pressed against the drain hole 12, the elastic material can fill any tiny irregular surfaces or gaps, thereby forming a tighter seal. This characteristic helps prevent liquid or gas leakage, ensuring a better sealing effect.

[0060] Specifically, the materials used to make the first plug 21 and the second plug 22 can be selected as needed. For example, the materials used to make the first plug 21 and the second plug 22 may include rubber, silicone, polyurethane, or fluorocarbon rubber, etc. This application does not limit this.

[0061] In the drainage assembly 10 of this embodiment, the drainage assembly 10 employs independent first plug 21 and second plug 22, enabling the first plug 21 to seal the water inlet 11 and the second plug 22 to seal the drain hole 12. When drainage is required, the second plug 22 opens the drain hole 12, while the first plug 21 remains sealed to the water inlet 11. This design ensures that during drainage, leakage of high-pressure gas caused by the opening of the water inlet 11 can be effectively avoided, reducing compressed air waste.

[0062] Reference Figure 1 and Figure 2 In some embodiments, the plug assembly further includes a transmission mechanism 23, which is configured to drive the first plug 21 to seal the inlet hole 11 when the second plug 22 opens the drain hole 12. This design ensures that when the drainage process begins (i.e., the second plug 22 opens the drain hole 12), the first plug 21 can respond immediately and seal the inlet hole 11. This synchronization mechanism effectively prevents high-pressure gas leakage through the inlet hole 11, ensuring stable operation of the air compressor. The mechanical linkage between the first plug 21 and the second plug 22 via the transmission mechanism 23 reduces the need for human intervention and lowers the risk of operational errors. This not only improves work efficiency but also increases the reliability and stability of the entire drainage assembly 10, making operation smoother and safer. The transmission mechanism 23 enables coordinated operation of the first plug 21 and the second plug 22 without adding an additional power source 5, thereby saving energy consumption. Furthermore, this design can reduce the overall size and weight of the drainage assembly 10, which is beneficial for applications in space-constrained environments.

[0063] Continue to refer to Figure 2 and Figure 3In some embodiments, the transmission mechanism 23 includes a first connecting rod 231 and a second connecting rod 232. The first connecting rod 231 is located inside the housing 1, and one end of the first connecting rod 231 is hinged to the first plug 21. The second connecting rod 232 is located inside the housing 1, and one end of the second connecting rod 232 is hinged to the other end of the first connecting rod 231. The other end of the second connecting rod 232 is hinged to the second plug 22. Thus, through the hinged design of the first connecting rod 231 and the second connecting rod 232, the first plug 21 and the second plug 22 can move synchronously, and the structure is simple. The hinged arrangement of the first connecting rod 231 and the second connecting rod 232 also makes the maintenance and replacement of the transmission mechanism 23 more convenient. When a connecting rod or plug malfunctions or needs to be replaced, it can be easily disassembled for repair or replacement, saving costs.

[0064] In some embodiments, the transmission mechanism 23 further includes a hinge portion 233 and a guide portion 234, with the other end of the first link 231 and one end of the second link 232 hinged together via the hinge portion 233. This design provides a stable connection between the first link 231 and the second link 232, while allowing the first link 231 and the second link 232 to rotate relative to each other within a certain range. The guide portion 234 is located inside the housing 1 and connected to the housing 1, and is used to guide the hinge portion 233. This design ensures that the hinge portion 233 moves along a predetermined path, avoiding unnecessary offset or shaking, allowing the first plug 21 to accurately open or seal the water inlet hole 11, and the second plug 22 to accurately open or seal the drain hole 12. In addition, the guide portion 234 can provide additional support and guidance, making the movement of the hinge portion 233 smoother and reducing the number of hinge portions 233. The noise and vibration during the movement of the first link 231 and the second link 232 are reduced, improving the comfort and durability of the transmission mechanism 23.

[0065] Reference Figure 4 and Figure 5 In some embodiments, the water inlet 11 includes a first section 111 and a second section 112. One end of the first section 111 is connected to the condenser pipe section 20, and the other end of the second section 112 is connected to the interior of the housing 1. Thus, the first section 111 is responsible for introducing condensate, and the second section 112 is responsible for guiding condensate into the housing 1. The first section 111 is connected to the end of the second section 112 near the drain hole 12. A first plug 21 is disposed within the second section 112. The first plug 21 can move towards the drain hole 12 to isolate the first section 111 and the second section 112, thereby preventing high-pressure gas from leaking from the water inlet 11. The first plug 21 can also move away from the drain hole 12 to connect the first section 111 and the second section 112, allowing condensate to smoothly enter the interior of the housing 1 through the water inlet 11.

[0066] It should be noted that the first hole segment 111 and the second hole segment 112 can be set straight or curved; specifically, this application does not limit this. Additionally, refer to... Figure 1 In the embodiments of this application, the second hole segment 112 extends along the direction of gravity, and the corresponding first hole segment 111 extends along the first direction, which intersects with the direction of gravity.

[0067] Reference Figure 1 In some embodiments, a limiting platform 113 protrudes from the inner wall of the second segment 112 near the drain hole 12. The limiting platform 113 abuts against the side of the first plug 21 facing the drain hole 12. Thus, when the first plug 21 moves to a specific position in the second segment 112, it abuts against the limiting platform 113, thereby limiting its further movement towards the drain hole 12. This limiting effect ensures that the first plug 21 remains within the second segment 112 during its movement, preventing it from detaching from the second segment 112. When the first plug 21 abuts against the limiting platform 113, the contact surfaces between them form a tight seal, thereby preventing high-pressure gas from leaking from the water inlet hole 11.

[0068] Reference Figure 1 and Figure 2 In some embodiments, the drainage assembly 10 further includes a first elastic element 31, which is elastically connected to the second plug 22 and the housing 1 to drive the second plug 22 to seal the drain hole 12. Thus, the presence of the first elastic element 31 allows the second plug 22 to automatically seal the drain hole 12 without external force. When it is necessary to close the drain hole 12, the elastic force of the first elastic element 31 drives the second plug 22 to fit tightly against the drain hole 12, thereby achieving a seal. This automatic sealing function improves the response speed and efficiency of the drainage assembly 10, achieving the closure of the drain hole 12 without additional operation or control mechanisms. The continuous elastic force provided by the first elastic element 31 ensures a tight contact between the second plug 22 and the drain hole 12, enhancing the reliability of the seal. Even under adverse conditions such as water pressure changes or external vibrations, the first elastic element 31 maintains sufficient elasticity to ensure that the seal does not fail. The introduction of the first elastic element 31 simplifies the structure and design of the drainage assembly 10, reduces manufacturing costs, and also improves the reliability and durability of the drainage assembly.

[0069] It should be noted that the type of the first elastic element 31 can be selected as needed. For example, the first elastic element 31 may include a spring or an elastic rope. Specifically, this application does not limit this.

[0070] In some embodiments, the drainage assembly 10 further includes a second elastic element elastically connected to the first plug 21 and the housing 1, for driving the first plug 21 to move toward the end away from the drain hole 12 to connect the first hole segment 111 and the second hole segment 112. Thus, the presence of the second elastic element allows the first plug 21 to automatically move toward the end away from the drain hole 12 without external force, thereby connecting the first hole segment 111 and the second hole segment 112. This automatic connection function improves the automation level of the drainage assembly 10, enabling smooth passage of condensate without manual intervention. Due to the automatic driving action of the second elastic element, operators do not need additional steps or equipment to move the first plug 21 when controlling the condensate. This simplifies the operation process, improves work efficiency, and reduces the possibility of operational errors.

[0071] Continue to refer to Figure 1 and Figure 2 In some embodiments, the drain hole 12 is located at the bottom of the tank 1. This placement of the drain hole 12 at the bottom of the tank 1 ensures that the liquid inside the tank 1 flows naturally to the drain hole 12 under gravity, thus achieving rapid and effective drainage. This design allows the liquid inside the tank 1 to be completely drained, preventing blockage of the drain hole caused by liquid stagnation and freezing inside the tank 1.

[0072] Refer again Figure 1 and Figure 2 In some embodiments, the diameter of the drain holes 12 decreases along the direction of gravity. This causes the flow velocity of liquid flowing through the drain holes 12 to increase relatively due to the gradually decreasing diameter (for a given flow rate, the flow velocity is inversely proportional to the cross-sectional area of ​​the flow channel). This helps the liquid drain from the tank 1 more quickly, improving drainage efficiency. The decreasing diameter design can act as a guiding mechanism, allowing the liquid to flow more smoothly along the direction of gravity. This design helps ensure that the liquid does not generate eddies or turbulence due to the change in diameter during drainage, thereby reducing energy loss and noise.

[0073] Continue to refer to Figure 1 and Figure 2 In some embodiments, the sidewalls of the second plug 22 are tapered along the direction of gravity. This causes the contact area between the second plug 22 and the drain hole 12 to decrease with increasing depth. This design makes it easier to install the plug into the drain hole 12, reducing the difficulty and resistance of sealing the drain hole 12 with the second plug 22.

[0074] Reference Figure 1 and Figure 2In some embodiments, the drainage assembly 10 further includes a power source 5, which is installed in the housing 1. The power source 5 drives the first plug 21 to open or close the water inlet 11. Thus, the introduction of the power source 5 enables automated control of the movement of the first plug 21. Through a preset program or signal, the power source 5 can accurately drive the first plug 21 to open or close the water inlet 11 without manual intervention, greatly improving the automation level of the drainage assembly 10. The first plug 21 driven by the power source 5 can reduce errors caused by improper human operation or negligence, thereby enhancing the reliability of the entire drainage assembly 10.

[0075] Reference Figure 1 and Figure 2 In one embodiment, the power source 5 is also used to drive the second plug 22 to move synchronously with the first plug 21. When the second plug 22 and the first plug 21 are driven by the same power source 5 and move synchronously, they can work together so that when the second plug 22 opens the drain hole 12, the first plug 21 (22) seals the water inlet hole 11, improving the working efficiency of the entire drainage assembly 10. Using a single power source 5 to drive the second plug 22 and the first plug 21 to move synchronously simplifies the control system. There is no need to set up separate power sources 5 and control circuits for the second plug 22 and the first plug 21, reducing the complexity and cost of the drainage assembly 10. At the same time, it also reduces the risk of failure of the drainage assembly 10. Driving the second plug 22 and the first plug 21 to move synchronously by a single power source 5 can optimize the spatial layout of the drainage assembly 10. There is no need to reserve installation space for the power source 5 for the second plug 22 and the first plug 21 separately, making the drainage assembly 10 more compact and simple. Using a single power source 5 to drive the second piston 22 to move synchronously with the first piston 21 simplifies maintenance and management. When power source 5 needs repair or replacement, only one component needs to be addressed, instead of two separate components. This reduces maintenance costs and workload.

[0076] It should be noted that the power source 5 can be selected as needed. The power source 5 may include an electric drive system, a pneumatic drive system, or a hydraulic drive system. Specifically, the electric drive system includes a servo motor or a stepper motor. The pneumatic drive system includes a cylinder. The hydraulic drive system includes a hydraulic cylinder. The electromagnetic drive system includes an electromagnet. In particular, this application does not limit the specific type of the power source 5.

[0077] In some embodiments, the drain assembly 10 further includes a power source 5, which is mounted on the housing 1 and is adapted to drive the transmission mechanism 23. The direct mounting of the power source 5 on the housing 1 makes the overall structure of the drain assembly 10 more compact and integrated. This design reduces external connecting parts, simplifies the installation process, and improves the aesthetics of the drain assembly 10. The fact that the power source 5 is adapted to drive the transmission mechanism 23 means that power can be directly and efficiently transmitted to the transmission mechanism 23. This design reduces energy loss during transmission, improves transmission efficiency, and enables the drain assembly 10 to respond more quickly to control signals, achieving the sealing of the inlet hole 11 by the first plug 21 (22) when the second plug 22 opens the drain hole 12.

[0078] In some embodiments, the power source 5 includes an electromagnet 51, which is adapted to the magnetic drive mechanism 23 to enable the drive mechanism 23 to move. Thus, the electromagnet 51 acts on the magnetic drive mechanism 23 through a magnetic field, achieving a non-contact driving method. This driving method avoids wear and noise caused by mechanical contact, improving the lifespan and reliability of the drive mechanism 23. As a power source 5, the electromagnet 51 has a relatively simple structure, making it easy to manufacture and install. Furthermore, since no complex mechanical transmission components are required, the overall structure of the drainage assembly 10 is also simpler. The electromagnet 51 does not consume energy when stationary; it only consumes electrical energy when the magnetic field is established or changes. Therefore, compared to some continuously operating power sources 5, the electromagnet 51 has lower energy consumption, contributing to energy conservation.

[0079] It should be noted that the strength of the magnetic field can be precisely controlled by adjusting the current or voltage of the electromagnet 51, thereby precisely controlling the movement speed and position of the transmission mechanism 23. Furthermore, in order to be magnetically driven by the electromagnet 51, at least a portion of the transmission mechanism 23 is made of magnetic material. In other embodiments, the transmission mechanism may not necessarily be driven by an electromagnet; instead, when the water pressure inside the tank is high enough, the second plug sealing the drain hole 12 floats up under the pressure to open the drain hole, and then the transmission mechanism moves the second plug to seal the water inlet hole 11.

[0080] In other embodiments, the power source 5 may also include a cylinder, a hydraulic cylinder, a linear motor, a stepper motor, or a servo motor, etc. Specifically, this application does not limit this.

[0081] Specifically, in the embodiments of this application, the hinge portion 233 is made of a magnetic material. This allows the electromagnet 51 to magnetically attract the hinge portion 233. Under the electromagnetic force of the electromagnet 51, the hinge portion 233 moves, causing a change in the angle between the first connecting rod 231 and the second connecting rod 232. This allows the first connecting rod 231 to move the first plug 21 to the sealed inlet while the second connecting rod 232 moves the second plug 22 to open the drain hole 12.

[0082] Of course, in other embodiments, at least a portion of the first link 231 and / or at least a portion of the second link 232 may be made of magnetic material. For example, the other end of the first link 231 and / or one end of the second link 232 may be made of magnetic material. Specifically, this application does not limit this.

[0083] In some embodiments, the drain assembly 10 further includes a liquid level detection unit 4 and a control unit 6. The liquid level detection unit 4 is installed in the housing 1 and is used to detect the liquid level inside the housing 1. The control unit 6 is installed in the housing 1 and is electrically connected to the liquid level detection unit 4 and the power source 5. The control unit 6 is used to control the operation of the power source 5 according to the liquid level signal output by the liquid level detection unit 4. Thus, the liquid level detection unit 4 monitors the liquid level inside the housing 1 in real time and transmits the liquid level signal to the control unit 6. The control unit 6 automatically controls the operating state of the power source 5 according to a preset logic or algorithm. This design achieves automated control of the drain assembly 10 without manual intervention, improving work efficiency and accuracy. The liquid level detection unit 4 can accurately detect the liquid level, providing accurate liquid level information to the control unit 6. Based on this information, the control unit 6 can precisely control the power source 5, enabling the drain assembly 10 to automatically start or stop working when the liquid level reaches a preset value, thereby achieving precise management of the liquid level. By precisely controlling the operating state of the power source 5, unnecessary energy waste can be avoided. For example, when the liquid level is low, the control component 6 can control the power source 5 to stop working, thereby saving energy. This design helps reduce the energy consumption of the drainage component 10 and improve energy utilization efficiency.

[0084] It should be noted that control component 6 can be integrated with a higher-level management system or network to achieve remote monitoring and intelligent management. By remotely accessing control component 6, the working status of drainage component 10 can be monitored in real time, and control strategies can be adjusted promptly, improving management efficiency and convenience.

[0085] In some embodiments, the level detection unit 4 includes an electrode-type level gauge. The electrode-type level gauge is a level detection device based on the conductivity of liquid. It typically consists of one or more electrodes. When the electrodes are immersed in the conductive liquid, the liquid acts as a conductor of current, making the circuit continuous. When the liquid level drops and the electrodes are exposed above the liquid surface, the circuit is broken. By detecting the on / off state of the circuit, changes in the liquid level can be accurately detected. The electrode-type level gauge has a simple structure and no complex mechanical parts, making it convenient to install and use. Due to the absence of complex moving mechanical parts, the electrode-type level gauge is less prone to failure during use and exhibits good stability. The electrode-type level gauge can monitor the liquid level inside the tank 1 in real time and accurately, providing a reliable level signal to the control component 6. The electrode-type level gauge has a simple structure, low maintenance costs, and can achieve automated control, reducing manual intervention and thus lowering overall operating costs. The stability and reliability of the electrode-type level gauge help ensure the normal operation of the drainage component 10 and avoid system failures or damage caused by inaccurate level detection.

[0086] In addition, in conjunction with the control component 6, the electrode-type level gauge can achieve automated control of the drainage component 10. When the liquid level reaches the preset value, the control component 6 controls the power source 5 to work according to the liquid level signal. The power source 5 causes the transmission mechanism 23 to move. When the second plug 22 opens the drainage hole 12, the transmission mechanism 23 drives the first plug 21 to seal the water inlet hole 11.

[0087] Reference Figures 1 to 3 In some embodiments, the electrode-type level gauge includes a first electrode 41, a second electrode 42, and a third electrode 43. The first electrode 41 and the second electrode 42 are both in contact with the bottom of the tank 1, while the third electrode 43 is spaced apart from the bottom of the tank 1 along the direction of gravity. This configuration ensures good contact between the electrodes and the liquid, especially at low liquid levels. The third electrode 43, spaced apart from the bottom of the tank 1 along the direction of gravity, allows it to contact the liquid when the level reaches a certain height, thus providing a detection signal for level changes. The three-electrode configuration provides more level detection points, helping to more accurately determine level changes and improve detection accuracy. In particular, the spaced arrangement of the third electrode 43 from the bottom of the tank 1 provides a more accurate detection signal when the liquid level is near full or at high levels requiring precise control. The multiple electrode configuration provides redundant detection; even if one electrode fails, the others can still provide level detection signals, ensuring the normal operation of the system.

[0088] Specifically, when the liquid level in the tank 1 rises to contact the third electrode 43, the first electrode 41 and the third electrode 43 become electrically connected. The control component 6 controls the power source 5 to operate, which in turn causes the transmission mechanism 23 to move. The transmission mechanism 23 then drives the first plug 21 to seal the inlet hole 11 while driving the second plug 22 to open the drain hole 12, thus facilitating the discharge of liquid from the tank 1. When the liquid level in the tank 1 is lower than the third electrode 43, the first electrode 41 and the second electrode 42 become electrically connected. The control component 6 continues to control the power source 5 to operate, keeping the second plug 22 in the position where the drain hole 12 is open and the first plug 21 in the position where the inlet hole 11 is sealed. The direct contact between the electrodes and the bottom of the tank 1 ensures that the liquid in the tank 1 is completely drained, preventing the drain hole from becoming blocked due to liquid stagnation and freezing inside the tank 1.

[0089] When the liquid inside the housing 1 is drained, the first electrode 41 and the second electrode 42 are electrically disconnected. In one embodiment, the control component 6 controls the power source 5 to stop working. Under the elastic force of the first elastic element 31, the second plug 22 automatically resets to the position of sealing the drain hole 12, while the first plug 21 automatically resets to the position of opening the water inlet hole 11. In other embodiments, the control component 6 can also control the power source 5 to work, and the power source 5 causes the transmission mechanism 23 to move. The transmission mechanism 23 drives the first plug 21 to open the water inlet hole 11 when driving the second plug 22 to close the drain hole 12, thereby facilitating the entry of external condensate into the housing 1.

[0090] According to a second aspect of this disclosure, a drain assembly 10 is provided, comprising a housing 1, a plug assembly, and an electrode-type level gauge. The housing 1 has a water inlet 11 and a drain outlet 12, thus enabling the entry and exit of liquid. The plug assembly is disposed within the housing 1 and includes a first plug 21 and a second plug 22. The first plug 21 seals the water inlet 11, and the second plug 22 seals the drain outlet 12. This allows for sealing either the water inlet 11 or the drain outlet 12 as needed. The electrode-type level gauge includes a first electrode 41, a second electrode 42, and a third electrode 43. Both the first electrode 41 and the second electrode 42 are in contact with the bottom of the housing 1, thus providing a stable liquid level detection reference. Simultaneously, the combined action of the first electrode 41 and the second electrode 42 allows the liquid inside the housing 1 to be completely drained. The third electrode 43 is spaced apart from the bottom of the housing 1 along the direction of gravity. This allows a detection signal to be triggered when the liquid level inside the housing 1 reaches a certain height. The multi-electrode configuration of the electrode level gauge provides accurate level detection capability, which can reflect the changes in the level in the tank 1 in real time, facilitating subsequent operations.

[0091] Reference Figure 1 and Figure 2In some embodiments, the drainage assembly 10 further includes a first elastic element 31, which is elastically connected to the second plug 22 and the housing 1 to drive the second plug 22 to seal the drain hole 12. Thus, the presence of the first elastic element 31 allows the second plug 22 to automatically seal the drain hole 12 without external force. When it is necessary to close the drain hole 12, the elastic force of the first elastic element 31 drives the second plug 22 to fit tightly against the drain hole 12, thereby achieving a seal. This automatic sealing function improves the response speed and efficiency of the drainage assembly 10, achieving the closure of the drain hole 12 without additional operation or control mechanisms. The continuous elastic force provided by the first elastic element 31 ensures a tight contact between the second plug 22 and the drain hole 12, enhancing the reliability of the seal. Even under adverse conditions such as water pressure changes or external vibrations, the first elastic element 31 maintains sufficient elasticity to ensure that the seal does not fail. The introduction of the first elastic element 31 simplifies the structure and design of the drainage assembly 10, reduces manufacturing costs, and also improves the reliability and durability of the drainage assembly.

[0092] It should be noted that the type of the first elastic element 31 can be selected as needed. For example, the first elastic element 31 may include a spring or an elastic rope, etc. Specifically, this application does not limit this.

[0093] Reference Figure 4 According to a third aspect of this disclosure, an air compressor assembly is provided, including a drain assembly 10 as described above and an air compressor. The structure of the drain assembly 10 is as described above. The air compressor includes a condenser section 20, which is connected to a water inlet 11. Since this air compressor adopts all the technical solutions of all the above embodiments, it has at least the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0094] In some embodiments, the condenser tube section 20 extends horizontally, and a drain hole 201 is provided on the lower side wall of the condenser tube section 20. This facilitates the timely discharge of condensate and avoids the negative impact of liquid accumulation on the condensation effect. The air compressor assembly also includes a liquid guide pipe 30, one end of which is connected to the drain hole 201. This ensures that condensate can flow smoothly into the liquid guide pipe 30. The other end of the liquid guide pipe 30 is connected to the water inlet 11. Thus, the condenser tube section 20, the liquid guide pipe 30, and the housing 1 directly form a complete drainage path, allowing condensate to ultimately exit the air compressor and enter the housing 1. The design of the drainage assembly 10 ensures the stable operation of the air compressor. The design of the condenser tube section 20 and the liquid guide pipe 30 allows condensate to be discharged in a timely manner, avoiding the decrease in condensation efficiency caused by liquid accumulation. The unobstructed drainage path ensures the continuity and stability of the condensation process and improves the overall performance of the air compressor.

[0095] Referring to Figure 5, in some embodiments, the periphery of the drain hole 201 is tapered along the direction of gravity. This means that the periphery of the drain hole 12 forms a funnel-like structure, and the drain hole 12 is positioned lower than its periphery, allowing liquid at the periphery to flow towards the drain hole 12 under gravity, facilitating the complete drainage of liquid within the condenser section 20 and accelerating the liquid discharge rate. This reduces liquid stagnation around the drain hole 201, ensuring that condensate can be quickly and smoothly discharged from the air compressor, reducing potential corrosion, leakage, or blockage problems caused by liquid stagnation, thereby improving the reliability and stability of the air compressor. Timely and effective drainage of condensate helps maintain the cleanliness and unobstructed flow of the condenser section 20, thus improving condensation efficiency. The tapered periphery of the drain hole 201 reduces liquid adhesion to the inner wall of the condenser section 20, lowering thermal resistance and further enhancing the condensation effect.

[0096] It should be noted that the perimeter refers to the outer boundary of an object or shape. For a drain hole, its perimeter refers to the edge surrounding the drain hole.

[0097] Reference Figure 5 In some embodiments, the orifice diameter at one end of the liquid guide tube 30 decreases along the direction of gravity. This results in a larger orifice diameter at the inlet end of the liquid guide tube 30 connecting to the drain hole 201 of the condenser tube section 20, which gradually decreases as the tube extends. This design optimizes the liquid flow characteristics and improves drainage efficiency. The decreasing orifice diameter at one end of the liquid guide tube 30 creates a "funnel effect," making it easier for condensate to flow into the liquid guide tube 30 under gravity and accelerating the liquid flow rate. This design reduces liquid retention at the inlet of the liquid guide tube 30, ensuring that condensate can be discharged quickly and smoothly. The decreasing orifice diameter design makes the liquid flow within the liquid guide tube 30 smoother, reduces flow resistance, and improves drainage efficiency.
