[0034] Reference Figures 1 to 3 According to an embodiment of the present invention, an exhaust system includes a housing 100 and a cover assembly 120. The cover assembly 120 covers the housing 100. The housing 100 includes an outer shell 101 and a chassis 102. The outer shell 101 is mounted on the upper part of the chassis 102 and has a mounting cavity 113. A container 109 for stirring kitchen waste is embedded in the mounting cavity 113, and an exhaust port 110 is provided on the outer periphery of the mounting cavity 113. Meanwhile, the chassis 102 has an upwardly protruding boss 105, and an exhaust chamber 106 is provided in the boss 105. The exhaust chamber 106 is equipped with an exhaust mechanism and is connected to an exhaust pipe 111 and a filter 112. Further, the cover assembly 120 has an air outlet 125, which is connected to the filter 112.

[0035] It is understood that the exhaust mechanism includes a motor (not shown in the figure), a fan (not shown in the figure), and a guide shroud 107. The fan is located inside the guide shroud 107, which is fixed to the top wall of the exhaust chamber 106. The exhaust mechanism can draw air from the container 109 through the suction port 110, the suction pipe 111, and the exhaust chamber 106, and deodorize it through the filter 112 before finally discharging it outside the housing 100 through the air outlet 125. Furthermore, the exhaust chamber 106 has an opening located on the bottom wall of the chassis 102, and the chassis 102 is provided with a removable cover plate 115 covering the opening, which facilitates the installation and disassembly of the exhaust mechanism and improves the assembly efficiency and maintenance convenience of the production process.

[0036] Specifically, refer to Figure 4 and Figure 5 The cover assembly 120 covers the top of the outer shell 101. The cover assembly 120 is provided with a first sealing ring 121 that fits against the outer periphery of the top of the container 109. The first sealing ring 121 has a notch 127, which corresponds to the air extraction port 110. The notch 127 ensures that the air inside the container 109 is exhausted through the air extraction port 110. It can be understood that, on the one hand, the first sealing ring 121 can press against the top of the container 109 to prevent the container 109 from shaking inside the housing 100. On the other hand, the first sealing ring 121 can prevent the gas inside the container 109 from leaking directly along the periphery. This helps to ensure that the air inside the container 109 is mainly exhausted through the air extraction port 110 and deodorized by the filter 112, thus avoiding the generation of odors during use.

[0037] Meanwhile, an air inlet gap 126 is provided between the inner wall of the cover assembly 120 and the housing 100. The air inlet gap 126 allows outside air to enter the housing 100. In fact, the air inlet gap 126 surrounds the outer periphery of the first sealing ring 121, and the air inlet gap 126 is connected to the inner cavity of the container 109 through the notch 127. It can be understood that during the exhaust process, the exhaust mechanism operates and extracts air from the container 109 through the air extraction port 110. At this time, the air pressure inside the container 109 decreases, and the air outside the housing 100 enters the housing 100 through the air inlet gap 126 under the action of atmospheric pressure, and enters the air extraction port 110 through the notch 127. That is, during the exhaust process, the air inside the container 109 and the outside air are simultaneously drawn into the exhaust port 110, so that the air pressure in the area between the cover assembly 120 and the box 100 is lower than atmospheric pressure, thereby preventing the gas in the container 109 from being discharged directly from the air inlet gap 126 without being processed by the filter 112 during the exhaust process, thus avoiding the generation of odors.

[0038] On the other hand, current food waste disposers have dedicated air inlets with one-way valves to prevent leaks, resulting in complex structures and high sealing requirements, leading to high manufacturing costs. The embodiments of this application utilize an air inlet gap 126 connected to the exhaust port 110 for air intake, effectively preventing odor leakage without overly stringent sealing, thus simplifying the structure of the food waste disposer and reducing manufacturing costs.

[0039] Reference Figure 3 It is understandable that the top of the outer casing 101 is also provided with a protrusion 114, and the air extraction port 110 is located on the side of the protrusion 114 near the container 109, which can increase the cross-sectional area of ​​the air extraction port 110, thereby improving the exhaust efficiency and preventing the leakage of odorous air.

[0040] Understandably, the filter 112 is located on one radial side of the container 109, and the suction pipe 111 is located between the container 109 and the filter 112, extending along the height direction of the housing 100. Specifically, the top of the boss 105 of the chassis 102 is provided with a first connector 103, and the top of the outer shell 101 is provided with a second connector 104, which is located below the protrusion 114. The upper and lower ends of the suction pipe 111 are respectively fitted onto the second connector 104 and the first connector 103. Furthermore, the suction pipe 111 is made of a flexible hose, such as silicone or polyurethane, so that the outer peripheral walls of the first connector 103 and the second connector 104 can elastically press against the inner peripheral wall of the suction pipe 111, thereby maintaining a good sealing effect. Furthermore, the outer peripheral walls of the first connector 103 and the second connector 104 are conical and press against the inner peripheral wall of the suction pipe 111. Thus, during installation, when the outer casing 101 is placed on the chassis 102, the outer peripheral walls of the first connector 103 and the second connector 104 can directly press against the inner peripheral wall of the suction pipe 111. The conical outer peripheral walls can improve the ease of installation and sealing effect of the first connector 103, the second connector 104 and the suction pipe 111, and avoid air leakage.

[0041] Reference Figure 5 It is understood that the cover assembly 120 is provided with a sealing assembly, which includes a second sealing ring 122 that fits against the outer periphery of the top of the filter 112. Since the air inlet gap 126 connects to the inner cavity of the container 109, a portion of odorous gas actually exists in the air inlet gap 126. The second sealing ring 122 can separate the air outlet 125 from the air inlet gap 126, thereby preventing odorous gas from being directly discharged from the air outlet 125. In some embodiments, the second sealing ring 122 surrounds the outer periphery of the filter 112 and presses against the top wall of the housing 101.

[0042] Furthermore, referring to Figure 3 The sealing assembly also includes a mesh plate 123 and a plug 124. A second sealing ring 122 is wrapped around the outer periphery of the mesh plate 123. The plug 124 is detachably inserted into the mesh plate 123 and the cover assembly 120, thereby enabling the sealing assembly to be detachably installed on the cover assembly 120. Furthermore, when the cover assembly 120 is closed and covers the upper part of the housing 100, the bottom wall of the plug 124 presses against the top wall of the filter 112, thereby ensuring that the filter 112 is stably inserted into the housing 100 and preventing the filter 112 from moving during the process of moving the food waste disposer.

[0043] According to an embodiment of the second aspect of this utility model, a food waste disposer is provided, including the aforementioned ventilation system. It is understood that the food waste disposer includes all the technical features of a ventilation system, and therefore the food waste disposer at least incorporates all the beneficial effects of a ventilation system.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
