Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to a waterproof air compressor. Background Technology

[0002] An air compressor is a device used to compress gases. It is widely used in many sectors of the national economy and national defense, especially in industries such as textiles, chemicals, and power, where it has become an indispensable key piece of equipment. It can provide sufficient compressed air pressure for automated production, which is essential for the smooth operation of the production process.

[0003] Traditional air compressors generate a significant amount of heat during operation. Over time, moisture in the air condenses inside the equipment, leading to water accumulation. This not only corrodes internal components but also significantly impacts the equipment's lifespan. While some existing waterproof air compressors utilize protective casings to mitigate the effects of external environmental factors, such designs often suffer from reduced heat dissipation efficiency, thus limiting the compressor's performance and long-term reliability.

[0004] Therefore, it is necessary to design a waterproof air compressor that can effectively prevent water from entering the air compressor while ensuring good heat dissipation performance, in order to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a waterproof air compressor that can effectively prevent water from entering the air compressor and ensure good heat dissipation performance.

[0006] The technical solution is as follows: A waterproof air compressor includes a waterproof casing, an air outlet pipe, an air collector hood, partitions, an air compressor housing, an impeller, a motor, a dustproof screen, louvers, heat dissipation fins, and an electric fan. The air outlet pipe is connected to the upper left side of the waterproof casing. A funnel-shaped air collector hood is fixed to the middle of the front part of the waterproof casing, with the air inlet facing forward and located at the center. Partitions are provided on each inner wall surface of the waterproof casing, forming a closed cavity. The partitions on the left side are connected to the air outlet pipe, and the partitions at the front are connected to the air collector hood. The air compressor housing is installed inside the closed cavity. The rear of the air compressor housing has a cross-shaped hollow design. The air outlet port of the air compressor housing is connected to the air outlet pipe. The air inlet port at the front of the air compressor housing corresponds to the rear end of the air collector shroud. An impeller is rotatably installed at the front of the air compressor housing. Motor 1 is installed at the rear of the air compressor housing. The output shaft of Motor 1 is connected to the central shaft of the impeller. A dustproof net is installed at the front of the air collector shroud. Louvers are installed in the middle of the air collector shroud. Heat dissipation fins are installed at the rear of the air compressor housing near Motor 1. An electric fan is embedded inside the waterproof shell and the rear partition, and the electric fan corresponds to the rear of the heat dissipation fins.

[0007] To further explain, it also includes heating wires and a grid. The heating wires are installed in the rear part of the air collecting hood, and the grid is installed on the front side of the impeller. The grid is housed in the rear part of the air collecting hood.

[0008] Further explanation: It also includes a mounting frame, louvers, bearing seats, a second motor, connecting rods, and synchronizing rods. The mounting frame is fixed to the rear of the waterproof housing. Several symmetrical louvers are rotatably arranged inside the mounting frame. Each louver and the rotating part of the mounting frame is provided with a bearing seat. The second motor is arranged on one side of the outside of the mounting frame. The output shaft of the second motor rotates through one of the bearing seats in the middle, and the output shaft of the second motor is connected to the rotating shaft of the 100 louvers in the middle. Each bearing seat is rotatably provided with a connecting rod at its end. The connecting rods on the same side are rotatably connected to each other by a synchronizing rod.

[0009] To further explain, it also includes a push handle; a U-shaped push handle is fixed to one side of the top of the waterproof shell.

[0010] To further explain, it also includes a baffle; a baffle is installed on the outer side of the waterproof shell above the air outlet duct.

[0011] To further explain, it also includes casters, with casters installed at each corner of the waterproof bottom.

[0012] Beneficial effects: 1. By combining a waterproof shell with a partition, this utility model ensures that the internal key components are not affected by external moisture intrusion; the combination design of heat dissipation fins and embedded electric fan effectively conducts and dissipates the heat generated by the motor, avoiding failures caused by overheating; the cross-shaped hollow design of the air compressor shell helps to evenly distribute pressure and improve the air compression effect.

[0013] 2. This utility model uses a louvered blade that is opened and closed by a motor, and all blades are rotated synchronously by a synchronizing rod, thereby adapting to different working conditions and flexibly adjusting the ventilation volume. It can increase cooling efficiency under high temperature conditions and reduce unnecessary energy consumption in low temperature or dry environments, achieving the dual goals of energy saving and high efficiency.

[0014] 3.

Detailed Implementation

[0024] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] Example: A waterproof air compressor, such as Figures 1-6As shown, the device includes a waterproof housing 1, an air outlet duct 2, an air collector hood 21, partitions 3, an air compressor housing 4, an impeller 41, a motor, a dustproof net 5, louvers 6, heat dissipation fins 9, and an electric fan 10. The waterproof housing 1 serves as the outer shell of the entire device, providing physical protection and preventing moisture from entering the internal components. The air outlet duct 2 is connected to the upper left side of the waterproof housing 1. The funnel-shaped air collector hood 21 is bolted to the middle of the front of the waterproof housing 1, guiding external air into the device. The air inlet of the air collector hood 21 faces forward and is located in the center. Partitions 3 are welded onto each inner wall surface of the waterproof housing 1, forming a closed cavity that enhances waterproof performance and provides a supporting structure for installing other components. The partitions 3 on the left side are connected to the air outlet duct 2, and the partitions 3 on the front side are connected to the air collector hood 21. The air compressor housing 4 is installed inside the closed cavity. The rear of the air compressor housing 4 has a cross-shaped hollow design. The air inlet is connected to the air outlet pipe 2. The air inlet at the front of the air compressor housing 4 corresponds to the rear end of the air collector hood 21. An impeller 41 is rotatably installed at the front of the air compressor housing 4. A motor 42 is installed at the rear of the air compressor housing 4. The output shaft of the motor 42 is connected to the central shaft of the impeller 41 through a coupling. The motor 42 provides power to the impeller 41, enabling the compression process. A dustproof net 5 is installed at the front of the air collector hood 21. A louver 6 is installed in the middle of the air collector hood 21. The louver 6 can adjust the airflow into the equipment to help control the temperature and pressure. A heat dissipation fin 9 is installed at the rear of the air compressor housing 4 near the motor 42. An electric fan 10 is embedded inside the waterproof shell 1 and the rear partition 3. The electric fan 10 corresponds to the rear of the heat dissipation fin 9. The heat dissipation fin 9 increases the heat dissipation area and helps to quickly dissipate the heat generated by the motor 42 during operation. The electric fan 10 provides forced ventilation, further improving the heat dissipation efficiency.

[0026] like Figure 4 As shown, it also includes a heating wire 7 and a grid 8. The heating wire 7 is installed in the rear part of the air collecting hood 21 by a clamp. The grid 8 is provided on the front side of the impeller 41. The grid 8 is housed in the rear part of the air collecting hood 21. The grid 8 provides additional safety protection and helps to guide the airflow.

[0027] like Figures 6-8As shown, it also includes a mounting frame 11, louvers 12, bearing seats 13, a second motor 14, a connecting rod 15, and a synchronizing rod 16. The mounting frame 11 is fixed to the rear of the waterproof housing 1. Several symmetrical louvers 12 are rotatably arranged inside the mounting frame 11. The louvers 12 adjust the airflow into the equipment by changing their opening and closing angles to adapt to different heat dissipation requirements. Each louver 12 has a bearing seat 13 at its rotation point with the mounting frame 11 via a pin. The bearing seat 13 supports and guides the rotational movement of the louver 12. To reduce friction, a second motor 14 is bolted to one side of the mounting frame 11. The output shaft of the second motor 14 passes through a bearing seat 13 in the middle, and the output shaft of the second motor 14 is connected to the rotation shaft of the 100 blades 12 in the middle by a flat key. Each bearing seat 13 has a connecting rod 15 rotatably mounted at its end. All connecting rods 15 on the same side are connected to a synchronizing rod 16 by a pin. The synchronizing rod 16 can link all the blades 12 to ensure that all the blades 12 open and close at the same angle at the same time.

[0028] like Figure 1 As shown, it also includes a pusher 17. A U-shaped pusher 17 is fixed to one side of the top of the waterproof shell 1 by welding. The pusher 17 makes it easy for the operator to move the entire equipment.

[0029] like Figure 1 As shown, it also includes a baffle 18. The baffle 18 is welded to the outer side of the waterproof shell 1 above the air outlet pipe 2. The baffle 18 prevents rainwater and other liquids from falling directly into the air outlet pipe 2.

[0030] like Figure 1 As shown, it also includes casters 101. Casters 101 are installed at each corner of the waterproof bottom with nuts. Casters 101 can improve the mobility of the equipment and make it easy to move.

[0031] During use, the operator places the equipment in a suitable working position and moves it to the required location easily using the push handle 17. The casters 101 make the machine easier to move, while the baffle 18 prevents rainwater or other liquids from falling directly into the air outlet duct 2. When the air compressor starts operating, the air inlet at the front of the air collector hood 21 first draws in outside air. To prevent dust and other impurities from entering the air compressor, a dustproof net 5 is installed at the front of the air collector hood 21. This layer of protection can effectively block larger particles and protect subsequent components from contamination. The drawn-in air passes through the louvers 6 and reaches the impeller 41 inside the air compressor housing 4. The motor 42 drives the impeller 41 to rotate, thereby compressing the drawn-in air. During this process, the cross-shaped hollow design of the air compressor housing 4 helps to evenly distribute pressure and ensure compression efficiency. The grille 8 not only provides further safety protection but also helps guide the airflow direction and improve the compression effect. Since the compression process generates heat, the heat dissipation fins 9 installed at the rear of the air compressor housing 4 directly contact the motor 42. The generated heat is quickly conducted away. At the same time, the embedded fan 10 blows air through these fins, accelerating the dissipation of heat. In addition, the heating wire 7 can adjust its own resistance value according to the ambient temperature to help maintain a suitable operating temperature range, especially to ensure normal start-up and operation of the equipment in cold environments. The compressed high-pressure gas is output from the front end of the air compressor housing 4 and discharged through the connected air outlet duct 2. In this process, if moisture is present, it will condense into water droplets at a lower temperature. However, the waterproof housing 1 seals the internal components and strengthens the sealing effect through the partition 3. Therefore, even if a small amount of water vapor is generated, it will not accumulate on the critical components and cause damage. In order to adapt to different working conditions, the louvers 12 in the mounting frame 11 can be opened and closed by the motor 14. The synchronizing rod 16 works with each louver 12 to make them open and close synchronously, so as to allow flexible control of the ventilation volume. This can increase the cooling efficiency under high temperature conditions and reduce unnecessary energy consumption in low temperature or dry environments.

[0032] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
