It should be understood that the present invention uses the terms "first", "second", etc. to describe various information, but such information should not be limited to these terms, which are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0047] like Figures 1 to 6 As shown, an intelligent sterilization and purification ceiling fan lamp according to a preferred embodiment of the present invention includes a top cover 2, a motor 3, a plurality of fan blades 4, a chassis 5, a lamp 6, an air filter 7 and an induction switch device 8. The top cover 2 is arranged on the top of the motor 3, and the motor 3 is provided with a fixed shaft 31 and a rotating disk 32 that can rotate around the fixed shaft 31. The top cover 2 is arranged above the motor 3 and is connected to the upper end of the fixed shaft 31. The fan blades 4 are connected to the rotating disk 32 and are driven to rotate by the motor 3. The chassis 5 is arranged below the motor 3 and is connected to the lower end of the fixed shaft 31. The chassis 5 is provided with an annular mounting area 51 and a middle mounting area 52; the lamp 6 is installed on the annular mounting area 51, and the The lamp 6 is provided with a lighting lamp 61 and an ultraviolet lamp 62; the air filter 7 is installed above the top cover 2, and the air filter 7 includes an outer cover 71 and a filter element 72 and a turbofan 73 arranged inside the outer cover 71. The turbofan 73 is connected to the filter element 72, and air flows through the filter element 72 under the action of the turbofan 73; the induction switch device 8 is installed on the middle installation area 52, and the induction switch device 8 is provided with a first induction switch 81 and a second induction switch 82. The first induction switch 81 is electrically connected to the input end of the controller, and the ultraviolet lamp 62 is electrically connected to the output end of the controller; the second induction switch 82 is electrically connected to the input end of the controller, and the turbofan 73 is electrically connected to the output end of the controller.

[0048] The key to implementing the intelligent sterilization and purification ceiling fan lamp provided by the embodiment of the present invention is: first, through the setting of the air filter 7, the turbine fan 73 is used to provide wind force to bring the indoor air into the filter element 72, and the free substances in the indoor air (such as dust and other particulate matter) are filtered. On the one hand, it can effectively improve the indoor air quality, and on the other hand, it can effectively prevent the problem of a large amount of dust and debris adhering to the fan blades 4 after the fan lamp has been idle for a long time, thereby reducing the number of regular manual cleanings by the end user; second, by arranging the lighting lamp 61 and the ultraviolet lamp 62 on the lamp 6, on the one hand, it can be used for daily lighting, and on the other hand, it can perform ultraviolet sterilization on the indoor air and articles. It has diverse functions and a high degree of integration, which reduces the purchase cost for consumers; and because the lamp 6 is installed on the ceiling fan, the effective space range of the light irradiation is large, and the sterilization effect of the ultraviolet lamp 62 is guaranteed; third, through the setting of the first sensor switch 81, taking the infrared sensor switch as an example, when the ultraviolet lamp is started, if the infrared sensor switch detects the infrared signal of the human body, the control The controller controls the ultraviolet lamp 62 to turn off. After the person leaves, that is, the infrared sensor switch can no longer detect the infrared signal of the human body, the controller controls the ultraviolet lamp 62 to turn on. It can be seen that the setting of the first sensor switch 81 can control the start and stop of the ultraviolet lamp 62 according to whether there is a person in its detection range, thereby avoiding ultraviolet radiation from irradiating the human body and causing harm, realizing intelligent control of ultraviolet sterilization, and achieving the purpose of safe use; Fourth, through the setting of the second sensor switch 82, taking the PM2.5 detector as an example, when the air quality detected by the PM2.5 detector is equal to or lower than the set value, the controller controls the turbo fan 73 to turn on to filter the indoor air; when the air quality detected by the PM2.5 detector is higher than the set value, the controller controls the turbo fan 73 to turn off; it can be seen that the setting of the second sensor switch 82 can control the start and stop of the ultraviolet lamp 62 according to the air quality within its detection range, realizing intelligent control of air filtration, thereby avoiding the ineffective operation of the air filter 7 and achieving the purpose of saving energy.

[0049] Exemplarily, the first sensor switch 81 can be an infrared sensor switch or a microwave sensor switch. It should be noted that, compared to infrared sensors, microwave sensors have a longer sensing distance, a wider angle, no dead zone, and can penetrate glass and thin wood. Depending on the power, they can penetrate walls of varying thicknesses. They are unaffected by the environment, temperature, dust, and other factors, and their sensing distance does not shorten even at 37 degrees. Therefore, microwave sensors are an ideal replacement for infrared sensors. However, to ensure the long-term normal operation of the first sensor switch 81, this embodiment includes two first sensor switches 81: one infrared sensor switch and the other microwave sensor switch.

[0050] Exemplarily, the second sensing switch 82 is preferably configured as a PM2.5 detector.

[0051] For example, in order to improve the aesthetics of the product and protect electrical components such as the lamp 6 and the induction switch device 8, the central installation area 52 is covered with an induction cabin cover 83, and the induction switch device 8 is arranged in the induction cabin cover 83; the annular installation area 51 is covered with a lampshade 63, and the lamp 6 is arranged in the lampshade 63.

[0052] Exemplarily, the first sensor switch 81 is positioned to protrude downward from the lampshade 63 to avoid being blocked by the lampshade, thereby ensuring the sensing range of the first sensor switch 81 (especially the infrared sensor switch).

[0053] Exemplarily, the sensing hatch 83 is provided with a sensing air hole 84 at a position close to the second sensing switch 82 (ie, the PM2.5 detector) to facilitate the operation of the PM2.5 detector.

[0054] For example, to conserve structural space, the illumination lamp 61 and the UV lamp 62 are integrated into a single lamp board, which features two control circuits corresponding to the illumination lamp 61 and UV lamp 62, respectively. The illumination lamp 61 comprises multiple LEDs arranged in a ring around the outer ring of the lamp board; the UV lamp 62 is a low-pressure mercury lamp arranged in a ring around the inner ring of the lamp board. Because ultraviolet rays can accelerate the aging of rubber and electronic components, the illumination lamp 61 and its associated electronic components are coated with a transparent UV-resistant coating, and a UV-resistant plastic cover is added to key electronic components. This allows the illumination lamp 61 and UV lamp 62 to be integrated onto the same substrate without affecting their performance, thus ensuring the longevity of the lamp 6.

[0055] Exemplarily, since the filter element 72 and the turbofan 73 are both arranged inside the outer cover 71, in order to save structural space and further optimize the design of the inlet and outlet channels, the outer shell of the filter element 72 is separated from the side wall of the outer cover 71 and forms an inlet channel, and the side wall of the outer cover 71 is provided with an inlet hole 74 connected to the inlet channel; the filtering path of the filter element 72 forms an outlet channel, and the top of the outer cover 71 is provided with an outlet hole 75 connected to the outlet channel; the inlet side of the turbofan 73 is connected to the inlet channel, and the outlet side of the turbofan 73 is connected to the outlet channel.

[0056] For example, since the lamp 6 and the inductive switch device 8 are suspended below the motor 3 via the chassis 5, the existing mounting structure of the lamp 6 is generally locked to the lower end of the fixed shaft 31 using bolts, nuts, etc. In addition, the lamp 6 needs to be connected to the power supply line by plugging or crimping. Therefore, such a mounting structure generally has the following disadvantages: First, the ceiling fan lamp cannot freely switch between the lamp 6 and the non-lighted decorative cover, which is not suitable for modular design, sales, and maintenance; Second, the wiring of the lamp 6 is inconvenient, making it difficult for the end user to replace the lamp panel. To address the above disadvantages, the embodiment of the present invention proposes a solution that does not require wiring or threaded locking, that is, the chassis 5 is connected to the lower end of the fixed shaft 31 via a wiring-free connector 9. Among them, the wire-free connector 9 includes an upper connector 91 and a lower connector 92 made of insulating material, the upper connector 91 is fixedly connected to the lower end of the fixed shaft 31, and the lower connector 92 is fixedly connected to the chassis 5. The upper connector 91 and the lower connector 92 are snap-fitted. The upper connector 91 is provided with a first positive conductive sheet 93 and a first negative conductive sheet 94, and the lower connector 92 is provided with a second positive conductive sheet 95 and a second negative conductive sheet 96. When the upper connector 91 is snap-fitted with the lower connector 92, the first positive conductive sheet 93 is connected to the second positive conductive sheet 95, and the first negative conductive sheet 94 is connected to the second negative conductive sheet 96.

[0057] In this embodiment, the buckle connection structure between the upper joint 91 and the lower joint 92 is specifically as follows:

[0059] During installation, it can be seen in advance that the lamp 6 and the inductive switch device 8 are installed on the chassis 5 and form an integral module. The two clips on the lower joint 92 are respectively aligned with the two guide ports on the upper joint 91 and inserted. When the clip moves to the corner position of the hook-shaped groove, it is rotated a certain angle until the clip is engaged with the engagement position at the end of the hook-shaped groove. The connection and fixation between the upper joint 91 and the lower joint 92 can be achieved, so that the integral module composed of the lamp 6, the inductive switch device 8 and the chassis 5 is fixed to the lower end of the fixed shaft 31.

[0060] Furthermore, to ensure the stability of the snap-fit ​​connection structure, the first hook-shaped groove 911 and the second hook-shaped groove 912 are respectively located on two symmetrical sides of the upper joint 91; the first clip 921 and the second clip 922 are respectively located on two symmetrical sides of the lower joint 92.

[0061] In this embodiment, the connection structure between the first positive and negative conductive sheets on the upper connector 91 and the second positive and negative conductive sheets on the lower connector 92 is specifically as follows:

[0062] The first positive conductive sheet 93 and the first negative conductive sheet 94 are both arranged in the wall of the upper connector 91, the upper end of the first positive conductive sheet 93 extends out of the upper end surface of the upper connector 91 to form a first positive terminal electrically connected to the power supply, and the upper end of the first negative conductive sheet 94 extends out of the upper end surface of the upper connector 91 to form a first negative terminal electrically connected to the power supply; the second positive conductive sheet 95 and the second negative conductive sheet 96 are both arranged in the wall of the lower connector 92, the lower end of the second positive conductive sheet 95 extends out of the lower end surface of the lower connector 92 to form a second positive terminal electrically connected to the lamp 6 and the induction switch device 8 respectively, and the lower end of the second negative conductive sheet 96 extends out of the lower end surface of the lower connector 92 to form a second negative terminal electrically connected to the lamp 6 and the induction switch device 8 respectively. Terminal; the first buckle 914 is provided with a first positive through hole 917 capable of exposing the lower end of the first positive conductive sheet 93; the first buckle 921 is provided with a second positive through hole 923 capable of exposing the upper end of the second positive conductive sheet 95; when the first buckle 921 is moved to the first buckle 914, the lower end of the first positive conductive sheet 93 contacts the upper end of the second positive conductive sheet 95; the second buckle 916 is provided with a first negative through hole 918 capable of exposing the lower end of the first negative conductive sheet 94; the first buckle 921 is provided with a second negative through hole 924 capable of exposing the upper end of the second positive conductive sheet 95; when the second buckle 922 is moved to the second buckle 916, the lower end of the first negative conductive sheet 94 contacts the upper end of the second negative conductive sheet 96.

[0063] In addition, in order to better achieve the connection and fixation between the upper joint 91 and the fixed shaft 31, the upper joint 91 is fitted and sleeved with the fixed shaft 31, and a first mounting hole 919 for connecting the upper joint 91 and the fixed shaft 31 is provided on the cylinder wall of the upper joint 91, and the first mounting hole 919 is a countersunk hole; in order to better achieve the connection and fixation between the lower joint 92 and the chassis 5, a radially extending connecting plate 925 is provided on the outer periphery of the upper end of the cylinder wall of the lower joint 92, and a second mounting hole 926 for connecting the lower joint 92 and the chassis 5 is provided on the connecting plate 925.

[0064] It can be seen that through the setting of the above-mentioned wiring-free connector 9, the overall module composed of the lamp 6, the induction switch device 8, and the chassis 5 can be quickly installed on the fixed shaft 31, and there is no need to use the plug-in or crimping process to connect the power supply line during the installation process, the climbing installation operation is convenient, and the end user can replace the lamp 6 more conveniently when the service life is reached; in addition, after using the above-mentioned wiring-free connector 9, the ceiling fan lamp can realize the free switching between the lamp 6 and the non-light decorative cover, which is conducive to modular design, sales and maintenance.
