[0044] A plurality of support feet 313 extending downwardly and arranged circumferentially are protruded from the bottom of the fire cap base 3, and the bottom of the support feet 313 is lower than the bottom of the air inlet 311, so as to ensure that the support feet can be used to reliably support the fire cap structure. In the embodiment, the number of the support feet 313 is four, and the four support feet are uniformly arranged along the circumferential direction of the bottom of the fire cap base 3. Each support foot 313 is located in the same vertical plane as the support portion 221 arranged close to it. In other embodiments, the support feet 313 and the support portions 221 can be designed to be staggered.

[0045] Embodiment 3

[0046] Reference Figures 6-8 The difference between the embodiment and the embodiment 2 is that the side plate 32 of the fire cap base 3 is detachably connected with the annular top plate 2, and at this time, the fire cap base 3 and the annular top plate 2 are two independent components from each other. In the embodiment, the radially outer end of the annular top plate 2 is integrally formed with a downwardly extending outer flange 212, and correspondingly, the upper end of the side plate 32 is provided with a second mounting position 314, which abuts or detachably connects with the outer flange 212 of the radially outer side of the annular top plate 2.
