Description

Technical Field

[0001] The utility model relates to a smoking lamp. Background Art

[0002] Ambient air is very important for human survival. The quality of air determines the quality of life and health of people. In the natural environment, we don’t need to pay too much attention to it, but in the daily life environment, it is difficult not to pay attention to the air quality of the surrounding small environment. For example: during the decoration period of the home environment, formaldehyde and other air will inevitably affect the air quality of the residents; the smoke in restaurants, offices and other environments will inevitably affect the air quality of the indoor environment; especially in mahjong rooms, smoking groups will inevitably affect the air quality in the surrounding small environment and affect the health of the respiratory system of people around them. Therefore, many air purification devices have been added to solve the above problems, such as using smoking lamps. Despite this, the following problems are still common:

[0003] In order to increase the suction of the smoking lamp, the usual practice is to increase the size of the wind wheel, but the larger the wind wheel, the greater the noise generated. Therefore, how to develop a smoking lamp that can reduce noise while having a large-sized wind wheel is the research direction that the staff in this field want to study. Utility Model Content

[0004] In view of the above-mentioned defects of the prior art, the purpose of the present utility model is to provide a smoking lamp.

[0005] The technical solution of the utility model is: a smoking lamp comprises a shell, a lampshade is installed at the lower end of the shell, an air inlet mesh cover is fixed in the middle of the lampshade, an upper cover is fixed at the upper end of the shell, a ventilation pipe is fixed at the upper end of the upper cover, a fixing seat is fixed at the upper end of the ventilation pipe, a motor frame is fixed at the lower end of the ventilation pipe, a motor is installed at the lower end of the motor frame, a wind wheel is connected to the output shaft at the lower end of the motor, a guide cover located above the wind wheel is fixed at the lower end of the motor frame, an air duct cover is fixed in the upper cover, an air duct inlet cover accommodated in the lower end of the air duct cover is fixed at the upper end of the shell, a guide channel is formed between the inner wall of the air duct cover, the inner wall of the air duct inlet cover, the outer wall of the wind wheel and the outer wall of the guide cover, the guide channel is connected with the lower end of the ventilation pipe, a plurality of fan blades are evenly distributed on the wind wheel, each fan blade has a plurality of guide holes that penetrate inside and outside, and the guide holes are connected with the guide channel.

[0006] Furthermore, a filter fixing seat is fixed in the shell, and a filter element located above the air inlet mesh cover is fixed on the filter fixing seat, and the filter element is located below the wind wheel.

[0007] Furthermore, a first arc-shaped concave surface is provided on the inner wall of the air duct inlet cover, and a second arc-shaped concave surface is provided on the inner wall of the air duct cover.

[0008] Furthermore, the motor frame has a through hole that penetrates inside and outside, and the upper end of the guide channel and the lower end of the ventilation pipe are both connected to the through hole.

[0009] The beneficial effect of applying the smoking lamp provided by the utility model is that after the smoke enters from the air inlet mesh cover, it enters the guide channel along the through hole of the wind wheel for guidance, and finally enters the ventilation duct. The first curved concave surface of the air inlet cover and the second curved concave surface of the air duct cover both play a role in alleviating the airflow, thus playing a role in reducing noise in the duct.

DETAILED DESCRIPTION

[0014] In order to more intuitively and completely understand the technical solution of the utility model, the following non-limiting feature description is now provided in conjunction with the accompanying drawings of the utility model:

[0015] like Figure 1 — Figure 3 As shown, the smoking lamp comprises a shell 1, a lamp bead (not shown) is installed in the shell 1, a lampshade 2 is installed at the lower end of the shell 1, an air inlet mesh cover 3 is fixed in the middle of the lampshade 2, an upper cover 4 is fixed at the upper end of the shell 1, a ventilation pipe 5 is fixed at the upper end of the upper cover 4, a fixing seat 6 is fixed at the upper end of the ventilation pipe 5, a motor frame 7 is fixed at the lower end of the ventilation pipe 5, a motor 8 is installed at the lower end of the motor frame 7, a wind wheel 9 is connected to the output shaft at the lower end of the motor 8, and a guide cover located above the wind wheel 9 is fixed at the lower end of the motor frame 7 10. An air duct cover 11 is fixed in the upper cover 4. An air duct inlet cover 12 accommodated in the lower end of the air duct cover 11 is fixed at the upper end of the shell 1. A guide channel 13 is formed between the inner wall of the air duct cover 11, the inner wall of the air duct inlet cover 12, the outer wall of the wind wheel 9, and the outer wall of the guide cover 10. The guide channel 13 is connected to the lower end of the ventilation pipe 5. A plurality of fan blades 91 are evenly distributed on the wind wheel 9. Each fan blade 91 has a plurality of guide holes 911 that penetrate inside and outside, and the guide holes 911 are connected to the guide channel 13.

[0016] like Figure 2As shown, a filter fixing seat 14 is fixed in the housing 1, and a filter element 15 located above the air inlet mesh cover 3 is fixed on the filter fixing seat 14, and the filter element 15 is located below the wind wheel 9. After the smoke enters from the air inlet mesh cover 3, the filter element 15 plays a filtering role.

[0017] like Figure 2 As shown, the inner wall of the air duct inlet cover 12 has a first arc-shaped concave surface 121, and the inner wall of the air duct cover 11 has a second arc-shaped concave surface 111.

After the smoke passes through the through hole 71 of the motor frame 7, it finally enters the ventilation duct 5. The first curved concave surface 121 of the air duct inlet cover 12 and the second curved concave surface 111 of the air duct cover 11 both play a role in moderating the airflow, thereby achieving the effect of reducing the noise of the duct.

[0020] The wind wheel 9 has a diameter of 315 mm and a height of 138 mm. When the wind speed is 1800 cubic meters per hour, the noise is 55 decibels; when the wind speed is 1500 cubic meters per hour, the noise is 50 decibels; when the wind speed is 1200 cubic meters per hour, the noise is 45 decibels.
