Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The utility model discloses an electromagnetism stove screwless installation fan structure, as shown in fig. 1 to fig. 3, including drain pan 1 and fan subassembly 2, fan subassembly 2 is located in the drain pan 1. As shown in fig. 3 to 5, the bottom case 1 includes a bottom plate 11, a first supporting block 12 and a second supporting block 132 are formed on the bottom plate 11, a supporting table 122 is formed on the first supporting block 12, a socket 121 is formed on an upper portion of the first supporting block 12, the socket 121 is located on one side of the supporting table 122, a baffle 13 is formed on the bottom case 1, the baffle 13 can be disposed perpendicular to the bottom plate 11, a hook 131 is formed on an upper end of the baffle 13, and the baffle 13 and the second supporting block 132 are disposed correspondingly. As shown in fig. 6, the fan assembly 2 includes a bracket 21 and a blade 22, wherein one end of the bracket 21 is formed with a plug end 211, the other end of the bracket 21 is formed with a buckling end 212, and the blade 22 is disposed between the plug end 211 and the buckling end 212. As shown in fig. 2, the upper end surface of the second supporting block 132 and the supporting table surface 122 are connected to the bottom surface of the bracket 21, the plug end 211 is inserted into the socket 121, the hook 131 is fastened to the upper side of the fastening end 212, as shown in fig. 8, a socket bottom 1211 is formed in the socket 121, as shown in fig. 2, the bracket 21 is positioned between the socket bottom 1211 and the baffle 13.

In the process of mounting the fan assembly 2 on the bottom case 1, as shown in fig. 7 and 8, the plug end 211 of the bracket 21 is inserted into the insertion opening 121 obliquely downward, then the buckling end 212 is swung downward, so that the buckling end 212 pushes the hook 131 away to make the baffle 13 elastically deformed and bent, after the hook 131 relatively passes over the buckling end 212, the hook 131 is buckled to the upper side of the buckling end 212 through the elastic recovery of the baffle 13, the baffle 13 abuts against the end surface of the buckling end 212, and the plug end 211 is also slid into the insertion opening bottom 1211 of the insertion opening 121 at the same time, at this time, the two ends of the bracket 21 are respectively supported by the upper end surface of the second supporting block 132 and the supporting table surface 122, thereby completing the assembly of the fan assembly 2 and the bottom case 1. The socket bottom 1211 is combined with the baffle 13 to position the bracket 21 in the front-rear direction (i.e., the opening direction of the socket 121), the hook 131 and the upper inner wall of the socket 121 are combined with the upper end surface of the second supporting block 132 and the supporting table 122 to position the bracket 21 in the up-down direction, and the socket 121 is positioned to position the plug end 211 in the left-right direction, so that the fan assembly 2 is stably installed in the bottom case 1. From the above, the installation the utility model discloses a fan subassembly 2 need not to use the screw, but adopts the quick buckle formula mounting structure that the above-mentioned described, then makes fan subassembly 2 simple to operate swift, is favorable to improving production efficiency, avoids leading to drain pan 1 to scrap because of installing self-tapping screw error moreover to be favorable to reduce cost.

Furthermore, as shown in fig. 5, positioning posts 133 are formed on the bottom plate 11, the positioning posts 133 are disposed on the left and right sides of the second supporting block 132 in a distributed manner, as shown in fig. 6, the bracket 21 is formed with long holes 2121, the positioning posts 133 are fittingly connected with the corresponding long holes 2121, the long holes 2121 are disposed in the opening direction of the socket 121, that is, the long holes 2121 extend in the front-back direction, and in the left-right direction, the positioning posts 133 are in clearance fit with the long holes 2121, so that in the process of inserting the bracket 21 into the socket 121 obliquely, the long holes 2121 can already be sleeved on the positioning posts 133, as the bracket 21 further slides into the socket 121, the positioning posts 133 also slide in the long holes 2121 relatively, and by providing the structure of the long holes 2121, the assembling process of the bracket 21 is facilitated, as shown in fig. 2, after the fan assembly 2 is installed, the positioning posts 133 play a role in the left-right direction positioning role of the bracket 21, thereby further stabilizing the installation of the bracket 21 and alleviating the vibration generated by the operation of the fan blade 22.

Further, as shown in fig. 2, the number of the baffle plates 13 is set to two, and the two baffle plates 13 are arranged side by side in the left-right direction, and then the number of the hooks 131 is set to two accordingly, it is possible to increase the positioning range of the butt joint end 212, and also to avoid difficulty in elastic bending of the baffle plates 13 due to too large width of the baffle plates 13, and thus to facilitate mounting.

Further, as shown in fig. 7 and 8, a relief notch 123 for avoiding the plug end 211 inserted into the socket 121 obliquely is formed between the support table 122 and the lower end of the socket 121, a socket upper chamfer 124 is formed at the upper end of the socket 121, the socket upper chamfer 124 serves to guide the plug end 211,

through the arrangement, the opening end of the socket 121 is equivalently enlarged, so that the plug end 211 can be conveniently inserted into the socket 121, and the mounting efficiency is improved.

Further, as shown in fig. 2, the bottom plate 11 is formed with an air inlet 1101, the first supporting block 12 and the second supporting block 132 are respectively located at two sides of the air inlet 1101, the fan blade 22 is located right above the air inlet 1101, the fan blade 22 is located at the lower side of the bracket 21, then the bracket 21 is arranged along the diameter direction of the fan blade 22, and the socket 121 is vertically opened toward the rotating shaft of the fan blade 22, specifically, the fan assembly 2 further includes a motor, the fan blade 22 is installed on the rotating shaft of the motor, the motor is installed at the lower side of the bracket 21, because the fan blade 22 is located right above the air inlet 1101, so that the air inlet is facilitated to be smooth, because the first supporting block 12 and the second supporting block 132 are respectively located at two sides of the air inlet 1101, which is favorable for the fan blade 22 to be stably supported.

Further, as shown in fig. 6, a vent hole 213 is formed on the bracket 21, and two vent holes 213 may be disposed on two sides of the rotation axis of the fan blade 22, as shown in fig. 2, since the bracket 21 is located above the air inlet 1101, the vent hole 213 is disposed to reduce the resistance of the bracket 21 to the airflow generated by the operation of the fan blade 22, which is also beneficial to reducing the weight of the bracket 21.
