[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-4 As shown, a conical drip hole 2 of a motor comprises a motor body 1 and two drip holes 2 arranged on the motor body 1. The drip hole 2 is a conical structure. The drip hole 2 is provided with a water collection port 21 and a water outlet 22. The taper is 1:10-1:20, and the aperture gradually decreases. In this embodiment, the taper is designed to be 1:15, and the aperture gradually decreases from less than or equal to 2 mm at the inlet to less than or equal to 0.5 mm at the outlet. The motor has good internal sealing, forming a near vacuum, and water cannot be discharged. Two drip holes are provided. The two conical drip holes can more effectively discharge water from the inside of the motor. Compared with a single larger conical drip hole, two smaller conical drip holes are easier to process and install, thereby improving production efficiency and reducing costs. The design of the conical drip hole 2 has the following advantages:

[0023] Smooth drainage: The conical design ensures that water droplets slide smoothly along the conical surface under the action of gravity, thereby effectively draining the moisture inside the motor and preventing moisture retention from causing damage to the motor.

[0024] Prevent backflow: The design of the conical drip hole 2 can prevent external moisture from backflowing into the motor under certain conditions (such as wind direction, air pressure, etc.), thereby protecting the motor from the influence of humid environment.

[0025] Reduce clogging: Compared with flat or linear drainage holes, the design of the conical drip hole 2 is more conducive to preventing the accumulation of impurities and dust, thereby reducing the risk of clogging of the drainage hole.

[0026] Enhanced Durability: The design of the tapered drip hole 2 can increase the structural strength of the drain hole, making it more able to withstand external pressure and impact, thereby extending the service life of the motor.

[0027] Easy to process and install: The design of the conical drip hole 2 is relatively simple, easy to process, manufacture and install, which is conducive to improving production efficiency and reducing costs.

[0028] In summary, the design of the motor conical drip hole 2 has obvious advantages in drainage, backflow prevention, blockage reduction, durability enhancement, processing and installation, etc.

[0029] In this embodiment, the inner wall of the drip hole 2 is smooth to improve the smoothness of water flow.

[0031] like Figure 2 and Figure 3 As shown, in this embodiment, the splash shield 3 is a semicircular or elliptical structure; the splash shield 3 is designed as a semicircular or elliptical structure has the following advantages:

[0032] Reduce splashing: the semicircular or elliptical structure can better adapt to the water flow and reduce splashing; easy to clean: this structure makes cleaning more convenient and can effectively avoid the appearance of sanitary dead corners.

[0033] Stable structure: Semicircular or elliptical structures have good structural stability and can withstand greater pressure and impact.

[0034] Easy to install: This structure makes installation more convenient and quick, and can improve installation efficiency.

[0035] Save space: Semicircular or oval structures are relatively compact and can better adapt to environments with limited space.

[0036] In general, the semicircular or elliptical structure of the splash guard 3 can better balance practicality and aesthetics and improve the user experience of the product.

[0037] like Figure 4 As shown, in this embodiment, a filter screen 4 is provided at the water collection port 21 of the drip hole 2 to prevent impurities from entering the drip hole 2 .

[0038] In this embodiment, the filter screen 4 is made of stainless steel; the stainless steel filter screen 4 also has high strength and stability, can withstand high pressure and temperature, and is not easily deformed or damaged; at the same time, the stainless steel filter screen 4 is also easy to clean and reuse, which can effectively reduce costs and reduce environmental pollution.

[0039] Working principle: Because the motor generates heat when it is working, after it stops running, the internal cooling humid air cools the condensation, and the condensed water inside the motor flows to the water collection port 21 of the drip hole 2, where the impurities carried by the condensed water are blocked by the filter 4, and the condensed water flows out from the water outlet 22 along the drip hole 2 and drips through the splash guard 3 set at the water outlet 22.

[0040] To summarize, the conical drip hole 2 of the motor is designed to be conical, and the conical design can ensure that water droplets slide smoothly along the conical surface under the action of gravity, thereby effectively draining the moisture inside the motor and preventing moisture retention from causing damage to the motor; the design of the conical drip hole 2 can prevent external moisture from flowing back into the motor under specific conditions (such as wind direction, air pressure, etc.), thereby protecting the motor from the influence of a humid environment; compared with a flat or linear drainage hole, the design of the conical drip hole 2 is more conducive to preventing the accumulation of impurities and dust, thereby reducing the risk of clogging of the drainage hole; the design of the conical drip hole 2 can increase the structural strength of the drainage hole, making it more able to withstand external pressure and impact, thereby extending the service life of the motor; the design of the conical drip hole 2 is relatively simple, easy to process, manufacture and install, and is conducive to improving production efficiency and reducing costs.
