Description

Technical Field

[0001] This invention relates to the field of range hood technology, and in particular to an LED light for a range hood and a control method thereof. Background Technology

[0002] LED lights in range hoods are an important component and play a vital role in the use of these hoods. However, due to environmental factors, LED lights are prone to damage. Currently, most range hood LED lights are wired, making disassembly for repair difficult and replacement complicated.

[0003] Chinese patent application number 201710262514.8, published on July 7, 2020, discloses a range hood, including a housing, a lamp holder on the housing, a lamp detachably mounted on the lamp holder, and an electrical connection point on the lamp holder that cooperates with the lamp. The lamp can be mounted on the lamp holder from outside the housing to enable the lamp to conduct electricity.

[0004] The lighting fixture is fixed to the lamp holder by a rotating locking mechanism. During installation, the latching part of the lighting fixture needs to be passed through the groove on the lamp holder, and then the lighting fixture needs to be rotated to rotate the latching part to the latching end in order to connect the lighting fixture to the lamp holder. The installation is complicated. At the same time, the latching part and the latching end are electrical connection points. The latching part and the latching end are used for both fixing and power transmission. The latching part and the latching end are prone to wear under stress, which may lead to abnormal power transmission. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an LED light for a range hood and a control method therefor. The LED light can be quickly installed and removed from the range hood, and the electrical connection is made simultaneously with the mechanical connection between the LED light body and the range hood, making installation simple.

[0006] To solve the above-mentioned technical problems, the technical solution used in this invention is as follows:

[0007] The present invention discloses an LED light for a range hood, comprising a mounting base and an LED light body. The mounting base includes a first fixing base and a second fixing base. The first fixing base is used for fixed connection with the range hood, and the second fixing base is fixedly connected with the LED light body. The first fixing base and the second fixing base are connected by a plug-in connection. The LED light body and the range hood are powered through a power terminal, which is separately disposed from the mounting base. The assembly direction of the first fixing base and the second fixing base is the same as the connection direction of the power terminal.

[0008] Preferably, a support structure is provided on both sides of the first fixed seat; a support structure is provided on both sides of the second fixed seat; the support structure is used to support the support structure.

[0009] Preferably, the support structure includes two support members disposed at the ends of the second fixed seat; the supporting structure includes two support grooves distributed along the axial direction of the first fixed seat; and the support members are accommodated in the support grooves.

[0010] Preferably, the mounting base also includes a limiting structure; after the first fixed base and the second fixed base are assembled and connected, the limiting structure is used to lock the first fixed base and the second fixed base.

[0011] Preferably, the limiting structure is disposed between the two support members to abut against the support groove and restrict the second fixing seat from disengaging from the first fixing seat.

[0012] Preferably, the limiting structure is a spring-loaded ball, the base of which is disposed on the side wall of the second fixed seat, and the locking body of which is used to abut against the support groove.

[0013] Preferably, the LED lamp body is provided with a mounting groove, and the second fixing seat is embedded in the mounting groove and fixedly connected to the LED lamp body.

[0014] Preferably, the LED lamp body is an integrated LED lamp body.

[0015] Preferably, the LED lamp body is magnetically connected to the range hood; the power terminal, the magnetic contact surface of the LED lamp body and the range hood are located on the same wall surface of the LED lamp body.

[0016] This invention also provides a method for controlling an LED light on a range hood, which is implemented using the LED light of the range hood, and includes the following steps:

[0017] S1. Preset PM2.5 concentration values ​​that match the color of the LED light body.

[0018] S2. Real-time acquisition of PM2.5 concentration values.

[0019] S3, the LED light body outputs a color corresponding to the current PM2.5 concentration value.

[0020] Compared with the prior art, the beneficial effects of the LED light for range hood described in this invention are mainly reflected in the following: the first fixing base and the second fixing base are connected by a plug-in connection. When installing the LED light body, simply insert the second fixing base into the first fixing base to connect the LED light body to the range hood. When disassembling the LED light body, simply pull the second fixing base out of the first fixing base to separate the LED light body from the range hood, thus enabling quick installation and removal of the LED light from the range hood.

[0021] The second mounting bracket is installed on the first mounting bracket in the same direction as the connection direction of the power terminal. Therefore, when the second mounting bracket is inserted into the first mounting bracket, the power terminal connection is performed simultaneously. This allows for both mechanical and electrical connection between the LED light body and the range hood; installation is simple.

[0022] The power terminals and mounting base are separate. The mounting base bears the force between the LED lamp body and the smoke hood, while the force connecting the LED lamp body and the smoke hood does not act on the power terminals, thus avoiding damage to the power terminals and ensuring high reliability.

[0023] The second fixed seat is connected to the first fixed seat by the cooperation of the support structure and the support structure; by setting support members at both ends of the second fixed seat, the support members are fixed in cooperation with the support groove, and the connection between the second fixed seat and the first fixed seat is stable.

[0024] By setting a limiting structure to lock the first fixed seat and the second fixed seat, the stability of the connection between the first fixed seat and the second fixed seat is improved; at the same time, the limiting structure is a spring ball, and the lock body of the spring ball abuts against the support groove.

[0025] When installing the LED light body, push the second fixing seat into the first fixing seat. Under the action of external force, push the lock body of the spring ball to contact the first end of the support groove, so that the lock body retracts against the elastic force of the spring, and the inner wall of the support groove restricts the extension of the lock body. Then continue to push the second fixing seat into the first fixing seat. When the spring ball passes the support groove, the lock body separates from the inner wall of the support groove. The spring returns to its original position and drives the lock body to extend. The lock body abuts against the second end of the support groove, restricting the separation of the second fixing seat from the first fixing seat.

[0026] When disassembling the LED light body, pull out the second fixing seat. Under the action of external force, the lock body of the spring ball is pulled to contact the second end of the support groove, so that the lock body retracts against the elastic force of the spring and the inner wall of the support groove restricts the extension of the lock body. Then continue to pull out the second fixing seat. When the spring ball passes the support groove, the lock body separates from the inner wall of the support groove, the spring resets and drives the lock body to extend, realizing the separation of the second fixing seat from the first fixing seat.

[0027] The mounting groove is designed to position the second mounting base, facilitating the assembly of the second mounting base with the LED lamp body. At the same time, the inner wall of the mounting groove can abut against the outer wall of the second mounting base, improving the connection stability between the second mounting base and the LED lamp body.

[0028] By designing an integrated LED light body, there are no assembly gaps, preventing oil fumes from entering the LED and causing damage. This extends the lifespan of the LED light body. The LED light body magnetically attaches to the range hood, ensuring a tight connection and guaranteeing reliable electrical connection.

[0029] Compared with the prior art, the present invention provides a control method for LED lights in a range hood, in which the color of the LED light body reflects the current PM2.5 concentration. Attached Figure Description

Detailed Implementation

[0043] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0044] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0045] like Figure 1-10 As shown, an LED light for a range hood includes a mounting base 1 and an LED light body 2. The mounting base 1 includes a first fixing base 11 and a second fixing base 12. The first fixing base 11 is used to fix the range hood 3, and the second fixing base 12 is fixedly connected to the LED light body 2. The first fixing base 11 and the second fixing base 12 are connected by a plug-in connection. When installing the LED light body 2, simply insert the second fixing base 12 into the first fixing base 11 to connect the LED light body 2 to the range hood 3. When disassembling the LED light body 2, simply pull the second fixing base 12 out of the first fixing base 11 to separate the LED light body 2 from the range hood 3, enabling quick assembly and disassembly of the LED light.

[0046] The LED lamp body 2 and the range hood 3 are powered through the power terminal, which is separately set from the mounting base 1. The mounting base 1 bears the force between the LED lamp body 2 and the range hood, and the force connecting the LED lamp body 2 and the range hood does not act on the power terminal, thus avoiding damage to the power terminal and ensuring high reliability.

[0047] The assembly direction of the first fixing seat 11 and the second fixing seat 12 is the same as the connection direction of the power terminal; when the second fixing seat 12 is inserted into the first fixing seat 11, the power terminal is connected at the same time, and the electrical connection is made at the same time as the mechanical connection between the LED lamp body 2 and the range hood 3.

[0048] Reference Figure 2 and Figure 9As shown, the second fixing base 12 is installed on the first fixing base 11 along the K1 direction, and the second fixing base 12 is detached from the first fixing base 11 in the opposite direction of the K1 direction. The power connection terminals include a first power connection terminal 21 disposed on the LED lamp body 2 and a second power connection terminal 31 disposed on the range hood 3. The first power connection terminal 21 of the LED lamp body 2 is connected to the second power connection terminal 31 of the range hood 3 along the K2 direction, and the first power connection terminal 21 of the LED lamp body 2 is separated from the second power connection terminal 31 of the range hood 3 in the opposite direction of the K2 direction; the K1 direction and the K2 direction are the same.

[0049] Supporting structures 111 are provided on both sides of the first fixed seat 11; supporting structures 121 are provided on both sides of the second fixed seat 12. The supporting structures 111 are used to support the supporting structures 121. The second fixed seat 12 is connected to the first fixed seat 11 by the cooperation of the supporting structures 121 and the supporting structures 111. The supporting structure 121 includes two supporting members 122, which are disposed at the ends of the second fixed seat 12; the supporting structure 111 includes two supporting grooves 112, which are distributed along the axial direction of the first fixed seat 11; the supporting members 122 are accommodated in the supporting grooves 112. By providing supporting members 122 at both ends of the second fixed seat 12, and fixing the supporting members 122 with the supporting grooves 112, the connection stability between the second fixed seat 12 and the first fixed seat 11 is good.

[0050] The mounting base 1 also includes a limiting structure 13. After the first fixed base 11 and the second fixed base 12 are assembled and connected, the limiting structure 13 is used to lock the first fixed base 11 and the second fixed base 12. The limiting structure 13 is disposed between the two support members 122 to abut against the support groove 112 and prevent the second fixed base 12 from disengaging from the first fixed base 11. By setting the limiting structure 13 to lock the first fixed base 11 and the second fixed base 12, the stability of the connection between the first fixed base 11 and the second fixed base 12 is improved.

[0051] Preferably, the limiting structure 13 is a spring-loaded ball bearing, the base of which is disposed on the side wall of the second fixed seat 12, and the locking body of which is used to abut against the support groove 112. The limiting structure 13 is a spring-loaded ball bearing, and the locking body of which abuts against the support groove 112.

[0052] When installing the LED light body 2, push the second fixing seat 12 into the first fixing seat 11. Under the action of external force, push the lock body of the spring ball to contact the first end of the support groove 112, so that the lock body retracts against the elastic force of the spring and the inner wall of the support groove 112 restricts the extension of the lock body. Then continue to push the second fixing seat 12 into the first fixing seat 11. When the spring ball passes the support groove 112, the lock body separates from the inner wall of the support groove 112. The spring resets and drives the lock body to extend. The lock body abuts against the second end of the support groove 112, restricting the separation of the second fixing seat 12 from the first fixing seat 11.

[0053] When disassembling the LED lamp body 2, the second fixing seat 12 is pulled out. Under the action of external force, the lock body of the spring ball is pulled to contact the second end of the support groove 112, so that the lock body retracts against the elastic force of the spring and the inner wall of the support groove 112 restricts the extension of the lock body. Then, the second fixing seat 12 is pulled out. When the spring ball passes the support groove 112, the lock body separates from the inner wall of the support groove 112, the spring resets and drives the lock body to extend, realizing the separation of the second fixing seat 12 from the first fixing seat 11.

[0054] In a preferred embodiment, the LED lamp body 2 is provided with a mounting groove 22, and the second fixing seat 12 is embedded in the mounting groove 22 and fixedly connected to the LED lamp body 2. By providing the mounting groove 22, the second fixing seat 12 is positioned, which facilitates the assembly of the second fixing seat 12 and the LED lamp body 2. At the same time, the inner wall of the mounting groove 22 can abut against the outer wall of the second fixing seat 12, thereby improving the connection stability between the second fixing seat 12 and the LED lamp body 2.

[0055] The LED lamp body 2 is a one-piece LED lamp body 2. By setting the LED lamp body 2 as a one-piece LED lamp body 2, there are no assembly gaps on the LED lamp body 2, which prevents oil fumes from entering the LED from the assembly gaps and causing damage. This improves the service life of the LED lamp body 2.

[0056] The LED lamp body 2 is magnetically connected to the range hood 3, with the power terminal 21 and the magnetic contact surfaces of the LED lamp body 2 and the range hood 3 located on the same wall surface of the LED lamp body. The magnetic engagement between the LED lamp body 2 and the range hood 3 ensures a tight connection between them, guaranteeing the reliability of the power terminal connection.

[0057] Preferably, a first magnetic suction member 23 is provided on the LED lamp body 2; a second magnetic suction member 32 is provided on the range hood 3; the first magnetic suction member 23 and the first power terminal 21 are disposed on the same wall surface of the LED lamp body 2; the second magnetic suction member 32 and the second power terminal 22 are disposed on the same wall surface of the range hood 3.

[0058] In a preferred embodiment, the LED light is connected to a PM2.5 sensor (not shown in the figure) and a light sensor (not shown in the figure) respectively. The PM2.5 sensor and the light sensor are installed on the cooking fume extractor. The PM2.5 sensor is used to detect the PM2.5 concentration, and the light sensor is used to detect the illumination brightness of the LED light on the cooktop.

[0059] The control method for the LED lights of a range hood includes the following steps:

[0060] S1, data matching the preset threshold brightness, preset PM2.5 concentration value, and the color of the LED lamp body 2;

[0061] S2. A light sensor detects the brightness of the LED light on the stove in real time, and a PM2.5 sensor obtains the PM2.5 concentration value in real time.

[0062] S3, LED lamp body 2 outputs a color corresponding to the current PM2.5 concentration value; based on the difference between the current brightness and the threshold brightness, the light intensity of the LED lamp is adjusted so that the light emitted by the LED lamp on the stove reaches the threshold brightness.

[0063] The above method uses the color of the LED light body 2 to reflect the current PM2.5 concentration; it also detects and adjusts the illumination brightness on the stove in real time to ensure the brightness of the light shining on the stove.
