DETAILED DESCRIPTION

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0024] See also Figure 1-Figure 5 The utility model provides a smoke purifier with a noise reduction component, which includes a shell body part 10 and a dust suction drive part 20.

[0025] Among them, the shell body part 10 cooperates with the dust suction drive part 20 to absorb the generated smoke and dust, and the dust suction drive part 20 can effectively reduce the noise generated by the negative pressure fan 210, reducing the impact of the noise of the smoke purifier on nearby people.

[0026] See also Figure 1 、 Figure 2 and Figure 4 The main body 10 of the shell includes a chassis 110, a dust collection component 120 and a filter 130. The dust collection component 120 is installed on the top of the chassis 110. The top of the chassis 110 is provided with an air inlet 140, and one side of the chassis 110 is provided with an air outlet 150. The filter 130 is installed inside the chassis 110 near the air outlet 150. The dust collection drive part 20 includes a negative pressure fan 210, a top ring plate 220, a corrugated hose 230, an elastic connector 240 and a sound-absorbing cotton sleeve 250. The negative pressure fan 210 is installed below the top ring plate 220, the corrugated hose 230 connects the top ring plate 220 with the air inlet 140, the elastic connector 240 connects the top ring plate 220 with the internal top wall of the chassis 110, and the sound-absorbing cotton sleeve 250 is sleeved on the outside of the negative pressure fan 210.

[0027] The negative pressure generated by the operation of the negative pressure fan 210 draws smoke and dust into the interior of the chassis 110 through the dust collection assembly 120. The air is filtered by the filter element 130 and ultimately discharged from the air outlet 150. The sound-absorbing cotton sleeve 250 on the outside of the negative pressure fan 210 can absorb as much noise as possible. The connection between the elastic connector 240 and the corrugated hose 230 reduces the noise generated by the negative pressure fan 210 due to vibration transmitted into the chassis 110, further achieving the purpose of noise reduction and achieving a better noise reduction effect.

[0028] The filter element 130 is a commonly used filter plate for smoke purifiers. The specific structural specifications are known to those skilled in the art and will not be described in detail.

[0029] In the above specific implementation, please refer to Figure 5 The elastic connector 240 includes a threaded rod 241, a lower flexible sleeve 242, and a nut 243. The bottom end of the threaded rod 241 is connected to the top ring plate 220, the top end of the threaded rod 241 passes through the top wall of the chassis 110, and the nut 243 is set at the top end of the threaded rod 241. The lower flexible sleeve 242 is sleeved on the outside of the threaded rod 241 located between the top wall of the chassis 110 and the top ring plate 220. The elastic connector 240 also includes an upper flexible sleeve 244, which is sleeved on the outside of the threaded rod 241 between the chassis 110 and the nut 243. Among them, the lower flexible sleeve 242 and the upper flexible sleeve 244 are both made of rubber sleeves with good shock absorption performance, which plays a good shock absorption role.

[0030] For details, please refer to Figure 2 The housing body 10 also includes wheels 160, which are located at the bottom of the housing 110. The wheels 160 facilitate the transfer of the entire device. The housing body 10 also includes a handle 170, which is installed on the outside of the housing 110. The handle 170 facilitates the movement of the purifier.

[0031] For further information, see Figure 3 The dust collection assembly 120 includes a shroud 121, a dust hood 122, and a shaped hose 123. The shroud 121 is located on the top of the chassis 110, and the ends of the shaped hose 123 are connected to the shroud 121 and the dust hood 122, respectively. The negative pressure generated by the operation of the negative pressure blower 210 drives air circulation inside the shroud 121, and external smoke and dust enter the interior of the box chassis 110 through the dust hood 122 and the shaped hose 123. The dust collection assembly 120 also includes a grille 124, which is located inside the dust hood 122. The grille 124 is provided to prevent large external objects from being sucked into the dust hood 122.

[0032] During specific configuration, one side of the chassis 110 includes a detachable inspection cover, which can be opened to inspect and install the device components inside the chassis 110.

[0033] It should be noted that the specific model and specifications of the negative pressure fan 210 need to be selected based on the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field and will not be described in detail. The power supply and principle of the negative pressure fan 210 are clear to those skilled in the art and will not be described in detail here.

[0034] The working principle of this smoke purifier with a noise reduction component is as follows: When in use, the negative pressure generated by the operation of the negative pressure fan 210 draws smoke and dust into the interior of the chassis 110 through the dust collection component 120. The air is filtered by the filter element 130 and finally discharged from the air outlet 150. The sound-absorbing cotton sleeve 250 on the outside of the negative pressure fan 210 can absorb as much noise as possible generated by the negative pressure fan 210. The connection between the elastic connector 240 and the corrugated hose 230 reduces the noise generated by the negative pressure fan 210 caused by vibration transmitted into the chassis 110, further achieving the purpose of noise reduction and having a better noise reduction effect.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
