The utility model reduces the use space of the desktop and the number of data cables used by integrating the wireless charging device on the power strip. At the same time, the external power cord of the power strip is generally longer, so that the user is not restricted by the position and the length of the data cable when using the wireless charging device. For example, the power strip with the wireless charging device can be used when it is far away from the fixed socket on the wall, and the charging of mobile phones and other devices can be easily completed. The plug wire can be extended or contracted relative to the shell, and will not be restricted by the length of the data cable. Mobile phones and other devices can be charged and used at any time, which improves the user's experience and satisfaction.

[0004] The applicant found that there are some shortcomings in use: the shell of the terminal block is directly exposed to the air, and dust will accumulate after long-term use. Too much dust can easily cause poor contact, and in severe cases it can cause local heating. When the temperature rises to a certain level, the socket will be deformed and may even cause a short circuit and cause a fire. At the same time, if water is accidentally spilled on the shell at home, it may cause a short circuit and damage to the internal components.

[0005] Therefore, the utility model designs a small household appliance housing to solve the problems existing in the prior art. Utility Model Content

[0011] Preferably, the heat dissipation assembly includes two heat dissipation grooves, which are respectively opened on both side walls of the protective cover, and dustproof plates are arranged in the heat dissipation grooves.

[0012] Preferably, an installation frame is installed on the inner wall of the heat dissipation slot, screw holes are opened at four corners of the installation frame, bolts are installed at four corners of the dustproof plate through threaded rotation, and the bolts are connected to the screw holes through threads.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model is provided with a protective component. When the utility model is in use and needs to be connected to electricity, the plug of the connecting line is inserted into the top of the shell, and then the protective cover is covered on the top of the shell. The connecting line is led out from the wire groove. The protection of the shell by the dust cover can reduce dust adhesion on the shell, reduce the situation of poor contact of the terminal block due to too much dust, and at the same time, the protective cover can also reduce the contact between water and the shell due to unexpected situations, reduce the situation of short circuit damage of components in the shell, and improve the safety of the terminal block through the protective component;

[0015] 2. The utility model dissipates heat through the setting of the heat dissipation component. After the protective cover is covered on the top of the shell, the heat is dissipated through the heat dissipation grooves on both sides to avoid the situation where the temperature inside the protective cover is too high. The dust-proof plate in the heat dissipation groove can filter dust and impurities in the air to avoid affecting the dust-proof effect of the protective component. When the dust-proof plate needs to be cleaned, unscrew the bolts to make the bolts leave the screw holes on the installation frame, and then the dust-proof plate can be taken out for cleaning.
