[0031] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0032] See also Figures 1 to 4The utility model discloses an air quality detection module. The air quality detection module disclosed in the utility model is used for a range hood, and includes a shell 1, a first air quality detection component 2 and a second air quality detection component 3. The shell 1 has a first cavity 11 and a second cavity 12 with openings facing upward, and the first cavity 11 and the second cavity 12 are connected; the first air quality detection component 2 is installed in the first cavity 11, and the first air quality detection component 2 has an air inlet side and an air outlet side, the air inlet side faces the second cavity 12, and the air outlet side faces the other side of the first cavity 11, and a fan is provided in the first air quality detection component 2; the second air quality detection component 3 is installed in the first cavity 11 and is located on the flow path of the airflow discharged from the air outlet side. The utility model discloses an air quality detection module. When it is applied to a range hood, the air quality detection module is installed in the electronic control cavity of the range hood. The shell 1 is connected to the lower surface of the cover of the range hood and is sealed with the cover. The cover is provided with an air inlet corresponding to the second cavity and an air outlet corresponding to the first cavity. When the air quality detection module is started, the fan of the first air quality detection component 2 is started, and the external air enters the second cavity 12 through the air inlet. Under the action of the fan, the external air flows from the second cavity to the air inlet side of the first air quality detection component 2, and then enters the first air quality detection component 2 through the air inlet side of the first air quality detection component 2. After being detected by the detection module in the first air quality detection component 2, the air is discharged through the air outlet side of the first air quality detection component 2. The airflow discharged from the first air quality detection component 2 flows in the first cavity 11 and blows toward the second air quality detection component 3. When flowing through the second air quality detection component 3, it is detected by the second air quality detection component 3, and then discharged from the air outlet corresponding to the first cavity 11.

[0033] In the air quality detection module of the present invention, a fan is arranged in the first air quality detection component 2, and the second air quality detection component 3 is arranged on the flow path of the air flow discharged from the air outlet side. The air discharged into the first cavity 11 by the first air quality detection component 2 can be detected by the second air quality detection component 3 when it is discharged from the first cavity 11. The second air quality detection component 3 does not need to be provided with a drainage device, and air flow will also flow through the second air quality detection component 3.

[0034] The air quality detection module of the present invention, the first air quality detection component 2 and the second air quality detection component 3 can be set up with different detection modules as needed to detect different indicators of pollutants in the air and meet the diverse needs of users.

[0035] In this embodiment, the detection module of the first air quality detection component 2 is a PM2.5 detection module, and the indicators detected by the first air quality detection component 2 are used to characterize the air purification effect of the range hood; the detection module of the second air quality detection component 3 is a methane sensor and / or a carbon monoxide sensor. The methane sensor is used to detect gas leakage. When the methane sensor detects that the gas exceeds the standard, it indicates that there is a gas leakage. The carbon monoxide sensor is used to detect the concentration of nitric oxide in the air. When the carbon monoxide sensor detects that the carbon monoxide concentration in the air exceeds the standard, it indicates that the gas combustion is incomplete when the user is cooking.

[0036] In this embodiment, a buzzer is also provided on the second air quality detection component 3. When the second air quality detection component 3 detects that the harmful gas in the air exceeds the standard, the buzzer alarms and reminds the user to avoid excessive toxic gas in the kitchen and affect the user's health.

[0037] See also Figure 4 In the air quality detection module of the present invention, a partition 13 is provided in the first cavity 11, and the partition 13 encloses a second cavity 12 having an air outlet. When the first air quality detection component 2 is installed in the first cavity 11, the air inlet side of the first air quality detection component 2 is connected to the second cavity 12 through the air outlet of the second cavity 12. In the illustrated embodiment, the first cavity 11 has a first wall and a second wall that are arranged oppositely and a third wall and a fourth wall that are arranged oppositely. A partition 13 is provided in the first cavity 11, and the partition 13 includes a first plate and a second plate. One side of the first plate is connected to the third wall, and the other side is connected to one side of the second plate. The other side of the second plate extends toward the first wall. The first plate, the second plate, and the parts of the third wall corresponding to the second plate enclose a second cavity 12 with an air outlet facing the first wall. When the first air quality detection component 2 is installed in the first cavity 11, the air inlet side of the first air quality detection component 2 faces the second cavity 12 through the air outlet of the second cavity 12. When the fan of the first air quality detection component 2 is started, the air in the second cavity 12 enters the first air quality detection component 2 through the air inlet side.

[0038] In the air quality detection module of the present invention, the distance from the other side of the second plate to the first wall is adapted to the thickness of the first air quality detection component 2. When the first air quality detection component 2 is installed in the first cavity 11, the other side of the second plate abuts against the corresponding side of the first air quality detection component 2. After the first air quality detection component 2 is installed in the first cavity 11, the first air quality detection component 2 blocks the air outlet of the second cavity 12 on the side facing the second cavity 12. When the fan of the first air quality detection component 2 is started, the fan draws air from the second cavity 12 through its air inlet side, so that a negative pressure is formed in the second cavity 12, which facilitates the entry of external airflow into the second cavity 12.

[0039] See also Figure 4 In the air quality detection module of the present invention, a first limiting rib 14 is provided in the first cavity 11. When the first air quality detection component 2 is installed in the first cavity 11, the partition 13 surrounding the second cavity 12 and the side wall of the first cavity 11 facing its air outlet limit the first air quality detection component 2 in the thickness direction of the first air quality detection component 2, and the first limiting rib 14 and the side wall of the first cavity 11 facing it limit the first air quality detection component 2 in the width direction of the first air quality detection component 2. In specific applications, the first limiting rib 14 is provided on the fourth wall. When the first air quality detection component 2 is installed in the first cavity 11, the second plate and the first wall limit it in the thickness direction, and the first limiting rib 14 and the third wall limit it in the width direction. When assembling the air quality detection module, the first air quality detection component 2 is installed from top to bottom from the opening above the first cavity 11, so that the thickness and width directions of the first air quality detection component 2 are limited. The first air quality detection component 2 can be installed in the first cavity 11, so that the first air quality detection component 2 is firmly installed in the first cavity 11.

[0040] See also Figure 4 In this embodiment, a first supporting rib 111 is provided on the first wall. When the first air quality detection assembly 2 is installed in the first cavity 11, the second plate and the first supporting rib 111 limit its position in the thickness direction and form a heat dissipation gap between it and the first wall. After the first air quality detection assembly 2 is installed in the first cavity 11, the first supporting rib 111 prevents the first air quality detection assembly 2 from being in close contact with the first wall, thereby facilitating heat dissipation from the first air quality detection assembly 2.

[0041] See also Figure 1 and Figure 4In the air quality detection module of the present invention, the second air quality detection component 3 is arranged opposite to the first air quality detection component 2, a second limiting rib 15 is provided on the wall of the first cavity 11, and a limiting block 16 is provided on the bottom surface of the first cavity 11. When the second air quality detection component 3 is installed in the first cavity 11, the limiting block 16 and the wall of the first cavity 11 arranged opposite thereto limit the second air quality detection component 3 from the thickness direction of the second air quality detection component 3, and the second limiting rib 15 and the wall of the first cavity 11 arranged opposite thereto limit the second air quality detection component 3 from the width direction of the second air quality detection component 3. In specific applications, the second air quality detection component 3 is arranged close to the second wall, the fourth wall is provided with a second limiting rib 15, and a limiting block 16 is provided on the bottom surface of the first cavity 11. When the second air quality detection component 3 is installed in the first cavity 11, the limiting block 16 and the second wall limit it from its thickness direction, and the second limiting rib 15 and the third wall limit it from its width direction. When assembling the air quality detection module, the second air quality detection component 3 is installed from top to bottom from the opening above the first cavity 11, so that the thickness and width directions of the second air quality detection component 3 are limited. The second air quality detection component 3 can be installed in the first cavity 11, so that the second air quality detection component 3 is firmly installed in the first cavity 11.

[0042] See also Figure 4 In this embodiment, second support ribs 112 are provided on the second wall. When the second air quality detection assembly 3 is installed in the first cavity 11, the stopper 16 and the second support ribs 112 limit its position in the thickness direction and form a heat dissipation gap between the second air quality detection assembly 3 and the second wall. After the second air quality detection assembly 3 is installed in the first cavity 11, the second support ribs 112 prevent the second air quality detection assembly 3 from being in close contact with the second wall, thereby facilitating heat dissipation from the second air quality detection assembly 3.

[0043] See also Figure 1 and Figure 3 In the air quality detection module of the present invention, the first air quality detection component 2 is provided with a first terminal 21, and the second air quality detection component 3 is provided with a second terminal 31. A first wire hole 113 corresponding to the first terminal 21 and a second wire hole 114 corresponding to the second terminal 31 are provided on the wall of the housing 1. The first wire hole 113 is used to connect the power cord to the first terminal 21 on the first air quality detection component 2, and the second wire hole 114 is used to connect the power cord to the second terminal 31 on the second air quality detection component 3, thereby connecting the first air quality detection component 2 and the second air quality detection component 3 to the main control circuit of the range hood.

[0044] See also Figure 1 and Figure 3In the air quality detection module of the present invention, a wire clip 115 is provided on the outer wall of the housing 1. After the power cord is connected to the first terminal 21 and the second terminal 31, it is arranged along the housing 1 and is clamped by the wire clip 115. The wire clip 115 is provided. After the wiring end of the power cord is connected to the first terminal 21 through the first wire hole 113 and to the second terminal 31 through the second wire hole 114, it is clamped by the wire clip 115, making the routing of the first air quality detection component 2 and the second air quality detection component 3 more regular.

[0045] See also Figures 1 to 3 The air quality detection module of the present invention also includes a seal 4, which is disposed along the upper edge of the first cavity 11 and the upper edge of the second cavity 12. In specific applications, a flange 116 extends outward from the upper edge of the first cavity 11, and the portion of the seal 4 corresponding to the upper edge of the first cavity 11 is disposed on the flange 116. When the air quality detection module is applied to a range hood, after the housing 1 of the air quality detection module is fixed to the top plate of the range hood's electronic control chamber, the seal 4 is squeezed between the top plate of the electronic control chamber and the upper edge of the housing 1. When the blower of the first air quality detection assembly 2 is activated, external air can only enter the second cavity 12 through the portion of the detection hole 52 that aligns with the second cavity, and cannot enter the first cavity 11 through the portion of the detection hole 52 that aligns with the first cavity. This creates a flow path for air to flow into the second cavity 12 and out of the first cavity 11, allowing both the detection module of the first air quality detection assembly 2 to detect air quality and the detection module of the second air quality detection assembly 3 to detect harmful substances in the air.

[0046] See also Figures 1 to 4 The air quality detection module of the present invention also has a third cavity 17 on its housing 1, located outside the first cavity 11. A buckle 171 and a third cable hole 172 are provided on the upper surface of the third cavity 17. When the air quality detection module is used in a range hood equipped with a negative ion purification module, the third cavity 17 will be used to install the high-voltage transformer of the negative ion purification module. After the high-voltage transformer is installed in the third cavity 17, the buckle 171 holds the high-voltage transformer in place. The power cord of the high-voltage transformer extends out of the third cavity 17 through the third cable hole 172 to connect to the main control circuit.

[0047] See also Figure 5 and Figure 6The present invention also discloses a range hood. The range hood disclosed in the present invention has the above-mentioned air quality detection module, including a range hood body 5. The range hood body 5 has an electric control cavity 51. A detection hole 52 is provided on the top plate of the electric control cavity 51. A part of the detection hole 52 is aligned with the first cavity 11, and the other part is aligned with the second cavity 12. When the fan of the first air quality detection component 2 is started, the external air enters the second cavity 12 through the part of the detection hole 52 aligned with the second cavity. The air in the second cavity 12 is discharged through the first air quality detection component 2 and then enters the first cavity 11, and then is discharged from the part of the detection hole 52 aligned with the first cavity. When the range hood is running, the air quality detection module is started, the fan of the first air quality detection component 2 runs and forms a negative pressure in the second cavity 12, and the external air enters the second cavity 12 through the detection hole 52 and the part aligned with the second cavity. The air in the second cavity 12 enters the first air quality detection component 2 through the air inlet side of the first air quality detection component 2, and then is detected by the detection module of the first air quality detection component 2 and discharged through the exhaust side of the first air quality detection component 2. The second air quality detection component 3 is installed in the first cavity 11 and is located on the flow path of the air flow discharged from the outlet side. The air discharged from the exhaust side passes through the second air quality detection component 3 in the process of flowing out of the first cavity 11, and the detection module of the second air quality detection component 3 detects the content of harmful gases in the air.

[0048] See also Figure 6 The range hood of the present invention also includes a negative ion purification module 6, which includes a negative ion purifying module 6 and a high-voltage package. The emitting end of the negative ion emitting module is used to generate negative ions outside the range hood body 5, and the high-voltage package is electrically connected to the negative ion emitting module; a third cavity 17 is also provided on the shell 1, and the high-voltage package is installed in the third cavity 17. The range hood has a purification mode. When the range hood starts the purification mode, the negative ion purification module 6 is started. The high-voltage package of the negative ion purification module 6 processes the input DC or AC power through the EMI processing circuit and the lightning protection circuit, and then upgrades it to AC high voltage through the pulse circuit, overvoltage current limiting, high and low voltage isolation and other lines. Then, it is rectified and filtered by special-grade electronic materials to obtain pure DC negative high voltage. The DC negative high voltage is connected to the release tip of the negative ion emission part made of metal or carbon elements. The DC high voltage at the tip is used to generate high corona, releasing a large number of electrons (e-) at a high speed. Electrons cannot exist in the air for a long time and will be immediately captured by oxygen molecules (O2) in the air, thereby generating air negative ions. Positively charged particles such as smoke, dust, and floating dust in the air can easily adsorb negative ions in the air, causing these dust particles to condense and become large particles that settle down. After the negative ions combine with bacteria in the air, the bacteria undergo structural changes or energy transfer, leading to the death of the bacteria. In this way, negative ions can also effectively remove various harmful substances in the air.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
