An aspect of the present invention provides a noise reduction box, noise reduction box includes casing 10, and the cavity has been injectd to the inside of casing 10, casing 10 on seted up with air inlet 101 and gas outlet 102 of cavity intercommunication, casing 10 be used for injecteing a part of cavity forms into transparent wall 20 to be convenient for observe through transparent wall 20 dirty degree in the cavity.
The utility model discloses a noise reduction box, through set up transparent wall 20 on casing 10, along with noise reduction box's use, dirty be stained with on transparent wall and attach the accumulation, transparent wall 20's transparency degree can change, the dirty degree of cavity viscera is higher, and transparent wall 20's transparency is lower more, from this alright judge the dirty degree of noise reduction box inside according to transparent wall 20's transparency degree to reach the effect that noise reduction box just can discern noise reduction box inside dirty degree easily not dismantled, whether convenient to use user decides to clean the maintenance to noise reduction box.
In the present invention, the noise reduction box may further include a light source 21, and the light source 21 may be disposed in the cavity for irradiating the transparent wall 20. Wherein the presence of the light source 21 ensures that the degree of transparency of the transparent wall 20 is clearly observed in each case, so that the degree of soiling in the cavity is more accurately obtained.
Since a fan is usually installed in the cavity, it is preferable to divide the cavity into a plurality of areas to facilitate installation of the fan and observation of the degree of contamination. Specifically, a baffle plate assembly may be provided in the cavity, and the cavity is divided into an inlet chamber 11, a fan mounting chamber 12, and an outlet chamber 13 by the baffle plate assembly. The air inlet 101 is communicated with the air inlet cavity 11, the air outlet 102 is communicated with the air outlet cavity 13, the air inlet cavity 11 is communicated with the fan installation cavity 12 through a first communicating port 141 arranged on the partition plate assembly, and the fan installation cavity 12 is communicated with the air outlet cavity 13 through a second communicating port 151 arranged on the partition plate assembly.
When in use, external air (for example, air) firstly enters the air inlet cavity 11 through the air inlet 101, then enters the fan installation cavity 12 through the first communication port 141, and the air entering the fan installation cavity 12 enters the fan, then enters the air outlet cavity 13 through the outlet of the fan and the second communication port 151, and finally is discharged through the air outlet 102. As can be seen from the above, the inlet chamber 11 should be the chamber which is most representative of the degree of soiling of the cavity, and therefore, in order to ensure the accuracy of the detection of the degree of soiling, the light source 21 may be arranged within the inlet chamber 11, with the transparent wall 20 forming part of the housing 10 defining the inlet chamber 11. It should be noted that the air inlet chamber 11 may be completely defined by the transparent wall 20, or may be partially defined by the transparent wall 20. In addition, the transparent wall 20 may be arranged on the housing 10 in any way, but it is preferable to ensure that there is no gap with the housing 10, so as to avoid that the gas in the cavity is lost through the gap.
In the above, the air inlet cavity 11, the fan mounting cavity 12 and the air outlet cavity 13 may have any suitable arrangement. According to an embodiment of the present invention, as shown in fig. 5, the air inlet 101 and the air outlet 102 are respectively located on two opposite side walls of the housing 10, and the partition plate assembly separates the cavity into the air inlet cavity 11, the fan installation cavity 12 and the air outlet cavity 13 along the direction from the air inlet 101 to the air outlet 102.

It can be understood that the air inlet cavity 11 and the fan installation cavity 12 are separated by a first partition plate 14, and the fan installation cavity 12 and the air outlet cavity 13 are separated by a second partition plate 15. The shape and arrangement of the first partition 14 and the second partition 15 can be designed according to the actual requirements of each chamber (i.e. the air inlet chamber 11, the fan installation chamber 12 and the air outlet chamber 13). Of course, the design of the inner space of the cavity is not limited to the above manner, and can be designed differently according to actual requirements.
In the above embodiment, in order to improve the convenience and clarity of viewing the transparent wall 20, as shown in fig. 5 and 6, the transparent wall 20 may be located on a side wall of the housing 10 opposite to the first barrier 14, and the light source 21 may be mounted on the first barrier 14.
Wherein the light source 21 may be mounted on the first partition 14 in any suitable manner. For example, a mounting seat 142 for mounting the light source 21 may be provided on the first partition 14. Specifically, as shown in fig. 3 and 5, the light source 21 may be a cylindrical lamp bead, the mounting seat 142 may be an annular structure extending from the first partition 14 toward the side where the transparent wall 20 is located, and the light source 21 is embedded in the annular structure. Of course, the light source 21 may be further connected to the mounting base 142 by bonding or the like, so as to improve the firmness and reliability of the installation of the light source 21.
In the present invention, the housing 10 may have any suitable structure, and the present invention is not limited thereto. For example, as shown in fig. 1-3, the housing 10 may include an upper housing 18 and a lower housing 19, and the upper housing 18 and the lower housing 19 may be fixedly connected, detachably connected, or rotatably connected.
