[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a moisture-proof, fully sealed protective electric motor, which significantly improves the motor's moisture resistance and dust resistance by setting a moisture-proof component 3 and a sealing component 4.

[0022] The support frame 5, moisture-proof board 6, and moisture-absorbing material layer 7 in the moisture-proof component 3 effectively absorb and block moisture, preventing it from entering the motor and thus improving the motor's moisture resistance. The sealing ring 8 and locking device in the sealing component 4 ensure a complete seal at the interface between the outer casing 1 and the motor body 2, preventing dust and moisture from penetrating. Through these technical means, the motor can effectively resist moisture and dust during use, improving its service life and performance.

[0023] In implementing the above technical solution, the design of the moisture-proof component 3 and the sealing component 4 is particularly crucial. The support frame 5 is fixedly connected to the inner surface of the outer casing 1, providing a stable support structure. The moisture-proof board 6 is fixedly connected to the inner side of the support frame 5, forming the first protective barrier. The moisture-absorbing material layer 7 is fixedly connected to the inner side of the moisture-proof board 6, further absorbing moisture and ensuring a dry environment inside the motor. The sealing ring 8 is installed at the interface between the outer casing 1 and the motor body 2, forming a tight sealing structure. The locking device 22 is used to fix the sealing ring 8, ensuring the sealing effect.

[0024] Compared with existing technologies, the moisture-proof, fully sealed protective motor of this application effectively solves the problem of poor moisture and dust resistance during use by setting moisture-proof component 3 and sealing component 4. In existing technologies, motors usually lack effective moisture-proof and sealing measures, making them easily damaged in humid and dusty environments. However, this application, through the rational design of moisture-proof component 3 and sealing component 4, significantly improves the moisture and dust resistance of the motor and extends its service life.

[0025] Specifically, the support frame 5, moisture-proof board 6, and moisture-absorbing material layer 7 in the moisture-proof component 3 work together to form a multi-layered protective structure, effectively preventing moisture from entering the motor. The sealing ring 8 and locking device 22 in the sealing component 4 ensure a complete seal at the interface between the outer casing 1 and the motor body 2, preventing the infiltration of dust and moisture. Thus, by providing the moisture-proof component 3 and the sealing component 4, the moisture-proof fully sealed protective motor of this application can effectively resist moisture and dust during use, improving the service life and performance of the motor.

[0026] Furthermore, this application also proposes that the motor body 2 includes a stator 9, a rotor 10 and an end cover 11, the rotor 10 is disposed inside the stator 9 and cooperates with it, and the end cover 11 is fixedly connected to both ends of the stator 9 to close the opening of the stator 9.

[0027] The stator 9 and rotor 10 of the motor body 2 cooperate to achieve the basic functions of the motor, while the end cover 11 is used to close the opening of the stator 9, thereby improving the protection and sealing performance of the internal components of the motor. Through this structural design, the influence of the external environment on the internal components of the motor can be effectively prevented, thus improving the service life and reliability of the motor.

[0028] In this design, the cooperation between the stator 9 and the rotor 10 is the core component for the motor to achieve its basic functions. The end cover 11 can be designed in various ways; for example, it can be made of a corrosion-resistant material to improve its durability in harsh environments. The method of fixing the end cover 11 can also be diverse; for example, it can be fixed with bolts or clips to ensure that the end cover 11 can securely seal the opening of the stator 9. Furthermore, to further improve the sealing performance, a sealing ring 8 or sealant can be placed between the end cover 11 and the stator 9 to prevent moisture and dust from entering the motor.

[0029] This application significantly improves the protection and sealing performance of the internal components of the motor by adding an end cover 11 to the motor body 2. Compared with the prior art, this application can more effectively prevent the external environment from corroding the inside of the motor, reduce failures caused by moisture and dust, thereby extending the service life of the motor and improving its reliability and stability.

[0030] Furthermore, this application also proposes that a dehumidifying bag 12 is provided on the support frame 5, and the dehumidifying bag 12 is detachable and replaceable.

[0031] A dehumidifier bag 12 is installed on the support frame 5. The dehumidifier bag 12 is removable and replaceable. The dehumidifier bag 12 is used to absorb moisture inside the motor, further improving the moisture-proof effect. The removable and replaceable design allows the dehumidifier bag 12 to be easily replaced after it becomes saturated, ensuring that the inside of the motor remains dry at all times, thus solving the problem of humidity control inside a moisture-proof, fully sealed protective motor.

[0032] The dehumidifier bag 12 can be made of various materials, such as silica gel desiccant and molecular sieves, which have high moisture absorption capacity and can be maintained through simple replacement. The dehumidifier bag 12 can be installed in multiple locations on the support frame 5 for easy replacement and inspection. The size and shape of the dehumidifier bag 12 can be adjusted according to the specific internal space of the motor to ensure that it does not affect the normal operation of the motor. Furthermore, the dehumidifier bag 12 can be fixed in various ways, such as using clips or adhesive, to ensure that it does not fall off during motor operation.

[0033] By installing a removable and replaceable dehumidifier bag 12 on the support frame 5, this application further improves the moisture-proof performance of the electric motor based on the prior art. Compared with the prior art, the technical solution of this application can effectively control the humidity inside the electric motor, extend the service life of the electric motor, and reduce failures and maintenance costs caused by moisture. Therefore, the technical solution proposed in this application has significant advantages in the design of moisture-proof, fully sealed protective electric motors.

[0034] Furthermore, this application also proposes that a buffer layer 13 is provided on the inner side of the outer shell 1, a sound insulation layer 14 is fixedly provided on the outer side of the buffer layer 13, and an anti-corrosion and wear-resistant layer 15 is tightly bonded to the outer side of the sound insulation layer 14.

[0035] The buffer layer 13 absorbs and disperses the vibration energy generated during motor operation, reducing the impact of vibration on the motor and its surrounding environment. The sound insulation layer 14 effectively reduces the noise generated during motor operation, improving the user experience. The corrosion-resistant and wear-resistant layer 15 enhances the motor's durability, preventing corrosion and wear on the housing 1, thereby extending the motor's service life. Through the above technical means, this application solves the problems of vibration and noise generated during motor use, improving the motor's stability and service life.

[0036] The buffer layer 13 can be made of a highly elastic material, such as rubber or polyurethane foam. The sound insulation layer 14 can be made of a porous material or composite material, such as sound-absorbing cotton or sound insulation board. The corrosion-resistant and wear-resistant layer 15 can be made of a corrosion-resistant and wear-resistant coating or composite material, such as a polytetrafluoroethylene coating or a ceramic coating. Specifically, the buffer layer 13 can be fixed to the inside of the outer shell 1 by adhesive or embedding, the sound insulation layer 14 can be fixed to the outside of the buffer layer 13 by adhesive or mechanical fixing, and the corrosion-resistant and wear-resistant layer 15 can be tightly bonded to the outside of the sound insulation layer 14 by spraying or adhesive.

[0037] This application effectively solves the vibration and noise problems generated by the electric motor during use by setting a buffer layer 13, a sound insulation layer 14, and a corrosion-resistant and wear-resistant layer 15 on the inner side of the outer casing 1, thereby enhancing the stability and service life of the electric motor. Compared with the prior art, this application provides a more comprehensive protection measure that can reduce vibration and noise, as well as prevent corrosion and wear, thereby improving the performance and reliability of the electric motor.

[0038] Furthermore, this application also proposes that the moisture-proof, fully sealed protective motor further includes a heat dissipation assembly 16, which includes a heat sink 17 and a cooling fan 18. The heat sink 17 is fixedly connected to the outer surface of the motor body 2, and the cooling fan 18 is disposed on the outer side of the housing 1 and corresponds to the heat sink 17.

[0039] These technical features play a crucial role in solving the heat dissipation problem. The heat sink 17 improves heat dissipation efficiency by increasing the surface area, while the cooling fan 18 further enhances the heat dissipation effect through forced convection. Together, they effectively reduce the temperature of the motor during operation, thereby ensuring normal motor operation and extending its service life.

[0040] The heat sink 17 can be made of a high thermal conductivity material, such as aluminum alloy or copper, to ensure high thermal conductivity. The shape and arrangement of the heat sink 17 can be optimized according to the specific structure of the motor to maximize heat dissipation efficiency. The cooling fan 18 can be a high-temperature resistant, low-noise model, and through reasonable installation position and angle design, it can effectively remove heat from the heat sink 17. Furthermore, a waterproof coating can be applied to the power lines of the cooling fan 18 to improve its service life and reliability in humid environments.

[0041] This application effectively solves the heat dissipation problem of the electric motor during operation by adding a heat dissipation component 16. Compared with the prior art, the electric motor of this application not only has moisture-proof and fully sealed protection performance, but also improves the heat dissipation efficiency of the electric motor, extends the service life of the electric motor, and ensures the stable operation of the electric motor in various complex environments through the combined use of heat sink 17 and cooling fan 18.

[0042] Furthermore, this application also proposes that the power lines of the cooling fan 18 are provided with a waterproof coating.

[0043] Waterproof coatings can be applied using various materials and processes, such as waterproof adhesives, silicone coatings, or waterproof paints. The thickness and coverage of the waterproof coating can be adjusted according to actual application requirements to ensure effective waterproof protection under different humidity and temperature conditions. Specifically, the waterproof coating can be evenly applied to the surface of the power lines by spraying, brushing, or dipping. As a preferred embodiment, the power lines can be cleaned and pre-treated before applying the waterproof coating to improve its adhesion and durability.

[0044] This application effectively solves the waterproofing problem of the cooling fan 18 in humid environments by applying a waterproof coating to the power line of the cooling fan 18. Compared with the prior art, the technical solution of this application has the following advantages: First, by adding a waterproof coating to the power line, moisture can be prevented from seeping into the power line, avoiding short circuits or damage to the power line caused by humid environments; second, it ensures that the cooling fan 18 can work normally in humid environments, thereby improving the overall moisture resistance and service life of the motor; finally, the technical solution of this application is simple and easy to implement, applicable to various types of cooling fans 18, and has high practical value and promotion prospects.

[0045] Furthermore, this application also proposes that a vibration damping component 19 is provided on the outer shell 1. The vibration damping component 19 includes an elastic support member 20 and a vibration damping pad 21. The elastic support member 20 is fixedly connected to the inner side of the outer shell 1, and the vibration damping pad 21 is disposed between the elastic support member 20 and the motor body 2 for absorbing and dispersing vibration energy.

[0046] The vibration damping assembly 19 consists of an elastic support 20 and a damping pad 21. The elastic support 20 is fixed inside the housing 1, and the damping pad 21 is located between the elastic support 20 and the motor body 2. The elastic support 20 provides elastic support, and the damping pad 21 absorbs and disperses vibration energy, thereby reducing the impact of vibration on the motor and improving the stability and service life of the motor.

[0047] The elastic support 20 of the vibration damping assembly 19 can be made of elastic materials such as rubber or springs to provide the necessary elastic support. The vibration damping pad 21 can be made of polymer materials, foam materials, etc., which can effectively absorb and disperse vibration energy. Through this design, the vibration generated by the motor during operation can be effectively absorbed and dispersed, reducing the impact on the motor and extending its service life.

[0048] This application effectively solves the vibration problem generated by the motor during operation by setting a vibration damping component 19 on the outer casing 1 and utilizing a combination design of elastic support 20 and vibration damping pad 21. Compared with the prior art, this application provides a simple and effective vibration reduction solution that can significantly improve the stability and service life of the motor and has high practical value.

[0049] Furthermore, this application also proposes that the outer shell 1 is made of a high-strength corrosion-resistant alloy material.

[0050] The technical solution of this application includes the basic structure of a moisture-proof, fully sealed protective electric motor, specifically comprising a housing 1, an electric motor body 2, a moisture-proof component 3, and a sealing component 4. By using a high-strength, corrosion-resistant alloy material to make the housing 1, it can maintain high strength and corrosion resistance in harsh environments, thereby improving the service life and reliability of the electric motor.

[0051] The application of high-strength, corrosion-resistant alloy materials can be achieved in various ways. For example, nickel-based alloys, titanium alloys, or other suitable alloys can be selected, as these materials possess excellent mechanical strength and corrosion resistance. Specifically, nickel-based alloys are commonly used in high-temperature and corrosive environments, while titanium alloys are widely used due to their lightweight, high strength, and excellent corrosion resistance. Furthermore, the outer shell 1 can be manufactured using casting, forging, or other suitable forming processes to ensure the full utilization of material properties.

[0052] This application solves the problems of insufficient corrosion resistance and strength of the housing material in the prior art by using a high-strength, corrosion-resistant alloy material to make the housing 1. Compared with the prior art, the motor of this application has higher reliability and service life in harsh environments, thereby improving the overall performance and application range of the motor.
