[0028] See also Figures 2 to 6 As shown, it discloses the first embodiment of the utility model, a motor housing structure 100 of a ceiling fan, which includes an upper housing 10 and a lower housing 20. The upper housing 10 can be fixedly connected to the lower housing 20 and enclose an internal space 101. The internal space 101 of the motor housing structure 100 of the ceiling fan can further accommodate a stator 102 and a rotor 103. The upper housing 10 and the lower housing 20 can be penetrated by a central axis 104.

[0029] The upper shell 10 has at least one upper side wall 11, and an upper opening 12 is provided on the side of the at least one upper side wall 11 adjacent to the lower shell 20. An upper hole 13 is provided on the side of the upper shell 10 away from the lower shell 20. The upper shell 10 is provided with the at least one upper side wall 11 between the upper hole 13 and the upper opening 12. An upper space 14 is formed inside the upper shell 10. The at least one upper side wall 11 adjacent to the upper opening 12 is laterally extended outwardly and protruded with a plurality of lugs 15. The plurality of lugs 15 are integrally formed with the upper shell 10, and the plurality of lugs 15 are arranged at intervals. The plurality of lugs 15 are longitudinally penetrated to form a lug space 16 respectively. The at least one upper side wall 11 has a connecting port 17 formed between the plurality of lug spaces 16 and the upper space 14 respectively. The plurality of lug spaces 16 are connected to the upper space 14 through the connecting ports 17. When the upper shell 10 is combined with the lower shell 20, the upper space 14 is located in the internal space 101.

[0030] The lower shell 20 is arranged below the upper shell 10. The lower shell 20 is provided with a lower hole 21. The upper hole 13 and the lower hole 21 can be used to pass the central axis 104. The lower shell 20 is provided with a butt top 22 corresponding to the upper opening 12, the at least one upper side wall 11 and the plurality of lugs 15. When the upper shell 10 is combined with the lower shell 20, the butt top 22 can be used to longitudinally support and butt against the at least one upper side wall 11 and prevent external air and dust from entering the internal space 101 through the upper opening 12. The lower shell 20 is provided with at least one blocking portion 23 corresponding to the upper opening 12, the at least one upper side wall 11 and the plurality of connecting ports 17.

The stopper 23 is arranged adjacent to the inner wall of the at least one upper side wall 11 for laterally supporting the upper shell 10. When the upper shell 10 is combined with the lower shell 20, the at least one stopper 23 blocks external air and dust from entering the internal space 101 through the plurality of the connecting ports 17. In addition, the abutting top 22 of the lower shell 20 is provided with a locking hole 24 corresponding to the plurality of lugs 15. The upper shell 10 can be locked in the locking hole 24 of the lower shell 20 by penetrating the lug spaces 16 of the plurality of lugs 15 through a plurality of locking members 25, and a plurality of columnar supporting structures are formed for longitudinally supporting the plurality of lugs 15 and the at least one upper side wall 11.
