[0030] Embodiment one

[0031] As shown in Figure 1 , Figure 2 and Figure 3 , the noise reduction box provided by the embodiment of the present application comprises: a shell 100, a blocking device 200 and a noise reduction filler 300; the noise reduction filler 300 is detachably mounted in the shell 100; the blocking device 200 is detachably connected with the shell 100, and the blocking device 200 is used to fix the noise reduction filler 300 in the shell 100.

[0032] Specifically, the noise reduction filler 300 is composed of one or more of sound-absorbing cotton, foamed plastic, aluminum fiber cotton, single-layer polyester fiber cotton, plant fiber spraying material or glass wool, etc. The noise reduction filler 300 is installed in the shell 100 and connected to the shell 100 through the blocking device 200, so as to block the noise reduction filler 300 in the shell 100. When the noise reduction filler 300 needs to be replaced, the blocking device 200 is first disassembled, and then the noise reduction filler 300 is taken out from the shell 100. After replacing the new noise reduction filler 300, the blocking device 200 is installed. When the noise reduction ability of the noise reduction filler 300 is reduced due to long-term adsorption of oil fume and cannot be replaced, the noise reduction filler 300 can be replaced to ensure good noise reduction performance of the noise reduction box, and the probability of oil fume overflow to the outside of the range hood due to long-term adsorption of oil fume on the noise reduction filler 300 can be reduced.

[0033] AsFigure 3 and Figure 4 As shown in FIG. 1 and FIG. 2, in the embodiment of the present application, the shell 100 comprises a side wall 101 and a baffle 102, the side wall 101 surrounds the noise reduction filler 300, and the side wall 101 is connected between the baffle 102 and the blocking device 200.

[0034] Specifically, the baffle 102 is provided with an opening penetrating the surface of the baffle 102, and the baffle 102 is connected to the side of the side wall 101 away from the blocking device 200. The baffle 102 can block the noise reduction filler 300 from escaping from the side away from the blocking device 200. The baffle 102 and the blocking device 200 jointly clamp the noise reduction filler 300, thereby fixing the noise reduction filler 300 in the inner cavity of the side wall 101. The airflow can pass through the noise reduction filler 300 in a direction perpendicular to the surface of the baffle 102. In use, the surface of the baffle 102 can be arranged in the plumb direction, and the baffle 102 can extend from the bottom frame of the side wall 101 to the inside of the side wall 101. The oil in the noise reduction filler 300 is lowered under the action of gravity and is prevented from flowing out by the baffle 102.

[0035] As shown in FIG. 3 and FIG. 4, the blocking device 200 is provided with a first clamping portion 201, and the side wall 101 is provided with a second clamping portion 103 matched with the first clamping portion 201. Figure 4

[0036] Specifically, one of the first clamping portion 201 and the second clamping portion 103 comprises a clamping groove, and the other comprises a clamping block. The clamping block is matched in the clamping groove, thereby connecting the blocking device 200 and the side wall 101. The blocking device 200 extends in the direction of the side wall 101, and the blocking device 200 abuts against the edge of the noise reduction filler 300. The blocking device 200 avoids the noise reduction filler 300 from escaping from the inner cavity of the side wall 101 in the direction away from the baffle 102. When it is necessary to disassemble the noise reduction filler 300, the blocking device 200 is compressed to shrink to the inside of the side wall 101, so that the clamping block escapes from the clamping groove, and then the blocking device 200 is separated from the shell 100.

[0037] Further, the side of the side wall 101 away from the baffle 102 is connected with a rim 104, the rim 104 extends to the inside of the side wall 101, and the rim 104 and the blocking device 200 respectively abut against the side of the noise reduction filler 300 away from the baffle 102.

[0038] Specifically, the side of the side wall 101 away from the baffle 102 is curved to form the rim 104, the rim 104 and the blocking device 200 jointly form a rectangular frame, and the rectangular frame abuts against the side of the noise reduction filler 300 away from the baffle 102, thereby fixing the noise reduction filler 300 in the inner cavity of the side wall 101.

[0039] As shown in FIG. 5 and FIG. 6, the blocking device 200 is provided with a first clamping portion 201, and the side wall 101 is provided with a second clamping portion 103 matched with the first clamping portion 201. Figure 2 ,​Figure 3 and Figure 4 As shown, the sealing device 200 and / or the edge portion 104 are provided with a wire mesh mounting portion 105, and the noise reduction filler 300 is provided with a mesh plate 400 on the side opposite to the baffle 102, and the wire mesh mounting portion 105 is connected to the mesh plate 400.

[0040] Specifically, the wire mesh mounting part 105 includes mounting posts, and the wire mesh plate 400 is provided with mounting holes adapted to the mounting posts. The mounting posts are inserted into the mounting holes to achieve the installation and fixation of the wire mesh plate 400. One of the blocking device 200 and the edge part 104 is provided with the wire mesh mounting part 105, or both the blocking device 200 and the edge part 104 are provided with the wire mesh mounting part 105. Multiple wire mesh mounting parts 105 are arranged at intervals along the edge of the wire mesh plate 400. The wire mesh plate 400 is fitted into the wire mesh mounting part 105, thereby connecting the blocking device 200 and the housing 100 to the wire mesh plate 400 respectively.

[0041] like Figure 1 and Figure 4 As shown, the side panel 101 is provided with a third latching part 106 adapted to the host to be installed.

[0042] Specifically, the main unit to be installed includes a range hood main unit 500 or other equipment requiring noise reduction. The third latching part 106 includes a protrusion disposed on the side panel 101 and protruding outward from the side panel 101. The mounting port of the range hood main unit 500 is provided with a fourth latching part 504 adapted to the third latching part 106. The fourth latching part 504 includes a slot. When the noise reduction box is installed in the mounting port, the protrusion is inserted into the slot, thereby fixing the noise reduction box at the mounting port.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the side panel 101 and / or the sealing device 200 are provided with an oil drain groove 107 that communicates with the inner cavity of the housing 100.

[0044] When the noise reduction box is installed on the range hood main unit 500, the oil drain trough 107 is located at the bottom of the noise reduction box and is connected to the inner cavity of the range hood main unit 500. The oil absorbed by the noise reduction filling component 300 flows downward under the action of gravity and flows into the inner cavity of the range hood main unit 500 through the oil drain trough 107, thereby allowing the oil to flow into the oil collection box of the range hood and thus preventing oil leakage.

[0045] Specifically, one of the side panel 101 and the sealing device 200 is provided with a slot, or the side panel 101 and the sealing device 200 are respectively provided with slots. When the side panel 101 is connected to the sealing device 200, an oil leakage groove 107 is formed through the slot to connect the inner cavity of the housing 100.

[0046] Further, the side wall plate 101 is connected with an oil blocking plate 108; the oil leakage groove 107 is located on the side of the oil blocking plate 108 away from the baffle 102.

[0047] Specifically, the oil blocking plate 108 extends downward from one end connected with the side wall plate 101, when the noise reduction box is installed on the range hood main machine 500, the oil blocking plate 108 is located inside the side wall of the cabinet of the range hood main machine 500, and the oil liquid discharged from the oil leakage groove 107 is blocked by the oil blocking plate 108, so as to avoid the oil liquid from seeping into the gap between the noise reduction box and the installation opening.

[0048] Further, the baffle 102 extends to the outside of the side wall plate 101 and forms a stop portion 109.

[0049] Specifically, the noise reduction box is inserted into the installation opening of the range hood main machine 500 from the outside to the inside, and the stop portion 109 abuts against the outer wall of the cabinet of the range hood main machine 500, thereby playing a limiting role on the noise reduction box. The side wall of the installation opening is clamped between the stop portion 109 and the oil blocking plate 108, thereby improving the positioning accuracy of the noise reduction box.

[0050] Embodiment two

[0051] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the range hood provided by the embodiment of the present application comprises: a range hood main machine 500 and the noise reduction box provided by the embodiment one, and the noise reduction box is installed on the range hood main machine 500.

[0052] Specifically, the shell 100 and the blocking device 200 form a hollow rectangular frame, the noise reduction filler 300 is installed in the rectangular frame, and the mesh plate 400 is located between the noise reduction filler 300 and the range hood main machine 500. When the range hood works, part of the oil fume is adsorbed by the noise reduction filler 300 and flows downward under the action of gravity, the oil liquid discharged through the oil leakage groove 107 enters the inner cavity of the range hood main machine 500 and finally flows into the oil collecting box. The noise reduction filler 300 is made of one or more of sound-absorbing cotton, foamed plastic, aluminum fiber cotton, single-layer polyester fiber cotton, plant fiber spraying material or glass wool, etc., and the noise in the interior of the range hood main machine 500 is blocked by the noise reduction filler 300, so as to achieve the purpose of noise reduction. And the noise reduction filler 300 and the mesh plate 400 jointly filter external impurities, so as to avoid larger particles from entering the interior of the range hood main machine 500.

[0053] In the embodiment of the present application, the range hood main machine 500 comprises: a cabinet 501 and a fan assembly 502 installed in the cabinet 501; the side wall of the cabinet 501 is provided with an installation opening and a flange portion 503, the flange portion 503 surrounds the installation opening, and the flange portion 503 is provided with a fourth buckle portion 504 matched with the shell 100.

[0054] The fan assembly 502 can be provided with one air inlet or two air inlets. When the fan assembly 502 is provided with one air inlet, the cabinet 501 is provided with the noise reduction box on the side opposite to the air inlet, or the cabinet 501 is provided with the noise reduction box on the side opposite to the air inlet, and the other side corresponding to the side is also provided with the noise reduction box. When the fan assembly 502 is provided with two air inlets, the cabinet 501 is provided with the noise reduction box on the side corresponding to the air inlet, so as to achieve better noise reduction effect.

[0056] It should be noted that when the noise reduction box is installed on the cabinet 501, the stop part 109 abuts against the outer wall of the cabinet 501, thereby limiting the noise reduction box. The oil baffle 108 is located on the side of the flange part 503 away from the stop part 109, and the oil baffle 108 can block the oil discharged from the oil leakage groove 107 from penetrating into the gap between the flange part 503 and the side wall 101. When replacing the noise reduction filler 300, the decorative plate 600 covering the outside of the cabinet 501 is first removed, the noise reduction filler 300 is taken out of the opening of the shell 100, and a new noise reduction filler 300 is installed in the shell 100. The noise reduction filler 300 is convenient to replace, and the technical problem that the noise reduction performance of the noise reduction filler 300 is reduced due to long-term adsorption of oil fume can be solved.

[0057] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
