DETAILED DESCRIPTION

[0027] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as: first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0028] Example 1

[0029] A fan screen housing with a blade locking structure, see Figure 1-Figure 5As shown, it includes an injection molded mounting shell 1, an injection molded bottom shell 101, a blade mounting portion 2 and a blade body 3. The lower part of the injection molded mounting shell 1 is connected to the injection molded bottom shell 101. Four blade mounting portions 2 are arranged on the injection molded mounting shell 1 at evenly spaced intervals in the circumferential direction. A groove that can accommodate the blade body 3 is arranged in the blade mounting portion 2. The blade body 3 is connected in the blade mounting portion 2. Slide grooves 4 are arranged on both sides of the blade mounting portion 2. Slots 5 corresponding to the slide grooves 4 are arranged on both sides of the blade body 3. A limit block 6 that is slidably connected to the slot 5 adjacent to the blade body 3 is arranged in the slide groove 4. The limit block 6 has a rounded corner on the side close to the blade body 3. When the blade body 3 moves downward to squeeze the limit block 6, the limit block 6 can be moved outward. Movement, two elastic members 7 are connected between the limit block 6 and the fan blade mounting part 2, a first mounting hole 15 is arranged in the fan blade mounting part 2, four groups of second mounting holes 16 for fixing the fan blade body 3 are evenly spaced in the injection molded mounting shell 1, and the number of each group of second mounting holes 16 is two, which are used to fix the fan blade body 3 close to the side of the injection molded mounting shell 1, an injection molded base layer 17 is arranged in the fan blade mounting part 2, and the thickness of the injection molded base layer 17 is 1 mm. When the fan blade body 3 is installed, the injection molded base layer 17 is tightly attached to the fan blade body 3, and the injection molded base layer 17 part ensures a better connection effect between the fan blade body 3 and the injection molded mounting shell 1, and also enables the fan blade body 3 and the injection molded mounting to have a better and stronger structural strength.

[0030] When installing the fan screen, first insert the blade body 3 into the blade mounting part 2 and the injection molding mounting shell 1. When the blade body 3 moves downward, the blade body 3 squeezes the limit block 6 to slide outward in the slide groove 4, and the limit block 6 squeezes the elastic member 7 to deform. When the slot 5 on the blade body 3 is aligned with the limit block 6, the elastic member 7 returns to its original state and drives the limit block 6 to be stuck in the slot 5, thereby quickly locking the blade body 3 in the injection molding mounting shell 1, so that the through hole 8 on the blade body 3 is quickly aligned with the first mounting hole 15 and the second mounting hole 16, which is convenient for quickly installing and fixing the blade body 3, thereby avoiding the blade body 3 from being out of position during installation.

[0031] Example 2

[0032] Based on Example 1, see Figure 6 and Figure 7 As shown, it also includes a motor shaft fixing sleeve 9 and a sealing ring 10. A through hole 8 is opened on the injection molding mounting shell 1, and square grooves are opened on both sides of the through hole 8. A motor shaft fixing sleeve 9 is slidingly arranged in the through hole 8, and protrusions are arranged on both sides of the motor shaft fixing sleeve 9. By inserting the protrusions on both sides of the motor shaft fixing sleeve 9 into the square grooves on both sides of the through hole 8, the connection between the motor shaft fixing sleeve 9 and the injection molding mounting shell 1 can be made more firmly. A sealing ring 10 is sleeved on the motor shaft fixing sleeve 9, and the sealing ring 10 is made of rubber material, which can better seal the motor shaft fixing sleeve 9 and the motor shaft.

[0033] By inserting the motor shaft fixing sleeve 9 into the through hole 8 of the injection molding mounting shell 1, and then inserting the motor shaft into the motor shaft fixing sleeve 9, the sealing ring 10 fills the gap between the motor shaft and the motor shaft fixing sleeve 9, thereby achieving the purpose of waterproofing the motor. When in use, the motor is started and the motor passes through the motor shaft fixing sleeve 9.

[0034] See also Figure 8 and Fig. 9 As shown, it also includes a clamping plate 12 and a clamping block 13. The injection molded mounting shell 1 is circumferentially provided with four vertical sliding grooves 11, and the clamping plate 12 is slidably arranged in the sliding groove 11. The injection molded bottom shell 101 is circumferentially fixed with four clamping blocks 13 corresponding to the clamping plate 12. The clamping plate 12 is provided with a clamping hole 14, and the clamping plate 12 is slidable to enable the clamping block 13 to be clamped with the clamping hole 14.

[0035] When the fan screen is not in use, slide the card plate 12 downward so that the card hole 14 on the card plate 12 is engaged with the card block 13, so that the card plate 12 limits the injection molded mounting shell 1 to prevent the fan blade body 3 from driving the injection molded mounting shell 1 to rotate when the fan screen is not in use, thereby preventing the fan blade body 3 from being damaged due to accidental rotation.
