In one specific embodiment, the multiple first connecting holes 1131 are linearly distributed in the left-right direction on the lower end of the back, and the multiple first connecting holes 1131 are distributed at intervals. In other examples, the multiple first connecting holes 1131 can also be distributed at intervals in an array. The clamping piece 1132 is used in cooperation with the clamping hole 2132 of the back plate assembly 2. The clamping piece 1132 can be clamped at the clamping hole 2132, so that the back plate assembly 2 is clamped with the smoke machine body 1, thereby playing a role of initial positioning and preliminary connection.

[0038] The number of clamping pieces 1132 can be one or more. When the number of clamping pieces 1132 is one, the clamping piece 1132 can be arranged in the middle area of the lower end of the back. When the number of clamping pieces 1132 is two, the clamping pieces 1132 can be arranged on the left and right side edge areas of the lower end of the back. When the number of clamping pieces 1132 is greater than two, the clamping pieces 1132 can be uniformly and interval distributed on the lower end of the back.

[0044] The installation structure of the back plate assembly, the back of the smoke machine body 1 has a groove opening towards the user side, the clamping piece 1132 is arranged in the groove and extends towards the user side, the back plate assembly 2 has a protrusion facing away from the user side, the clamping hole 2132 is arranged on the protrusion, when the back plate assembly 2 is connected with the smoke machine body 1, the protrusion is connected in the groove, and the clamping piece 1132 is inserted into the clamping hole 2132. Figures 2 to 5As shown, a protrusion can be formed on the back plate assembly 2 from front to back by punching, and a clamping hole 2132 is formed on the top of the protrusion (i.e. the side facing away from the user) to penetrate the protrusion in the thickness direction. When the back plate assembly 2 is installed with the range hood body 1, the clamping piece 1132 is aligned with the clamping hole 2132, and then the protrusion is gradually inserted into the groove. During the process of inserting the protrusion into the groove, the clamping piece 1132 passes through the clamping hole 2132. The cooperation of the protrusion and the groove improves the positioning convenience of the clamping piece 1132 and the clamping hole 2132, facilitates the insertion of the clamping piece 1132 into the clamping hole 2132, and can be more accurately positioned to facilitate the clamping operation of the back plate assembly 2 and the range hood body 1. Moreover, the cooperation of the protrusion and the groove increases the contact area of the back plate assembly 2 and the range hood body 1, and the relative limiting of the protrusion and the groove improves the reliability of the connection between the back plate assembly 2 and the range hood body 1. The cooperation structure of the protrusion and the groove not only can realize the preliminary positioning of the back plate assembly 2 and the range hood body 1, but also can increase the stability of the connection to prevent the back plate assembly 2 from shifting during use. At the same time, the clamping piece 1132 is inserted into the clamping hole 2132, which further strengthens the connection strength between the back plate assembly 2 and the range hood body 1, ensures that the back plate assembly 2 will not fall off during the operation of the range hood, and improves the overall stability and safety of the range hood. Through this design, the installation structure of the back plate assembly not only realizes quick and convenient assembly, but also improves the overall performance and service life of the range hood.
