Description

Technical Field

[0001] The present invention relates to the technical field related to medical lighting, and in particular to a novel medical lighting device. Background Art

[0002] Lighting is a measure that uses various light sources to illuminate work and living places or individual objects. Lighting that uses the sun and sky is called "natural lighting", and light that uses artificial light is called "artificial lighting". Doctors often use lighting devices when diagnosing patients to facilitate doctors to check the diseased parts. Lighting lamps will generate a lot of heat when they are turned on for a long time. If the heat is not dissipated in time, the service life of the lighting lamp will be affected.

[0003] For example, a medical lighting device proposed in a Chinese patent (CN211083796U) drives a rotating shaft to rotate by connecting a micro motor. Under the action of a first gear and two second gears, the rotating shaft drives two threaded rods to rotate. Since the two slide rods are threadedly connected to the two threaded rods, the rotation of the two threaded rods drives the two slide rods to move. The micro motor is adjusted to rotate forward and reversely while two fans are connected. The two slide rods drive the two fans to move back and forth. The air blown by the two fans directly acts on the lamp tube, and the two fans move back and forth to dissipate heat for the lamp tube.

[0004] In the above application, heat is discharged through the dust cover. However, under long-term working conditions, a lot of dust will adhere to the surface of the dust cover, which will affect the efficiency of heat discharge inside the lighting device and reduce the heat dissipation effect of the lighting device. At the same time, in the above application, the heat dissipation strip of the heat conductive block is cooled by adding water to the sponge. This method requires users to operate frequently, which brings inconvenience to users. Summary of the invention

When replacing the first dust-proof net 5 or the second dust-proof net 6, it is only necessary to remove the bolts fixing the first dust-proof net 5 or the second dust-proof net 6. It is convenient and simple and easy to operate.

[0039] The bottom of the bracket 1 is provided with five universal wheels, which is convenient for users to push the lighting device, and the universal wheels are provided with brake pads, which is convenient for users to fix the position of the lighting device;

[0040] A heat dissipation motor 7 is fixedly arranged inside the lampshade 2, and a heat dissipation fan 8 is connected to the output shaft of the heat dissipation motor 7. The heat dissipation fan 8 is driven by the heat dissipation motor 7 to rotate, and the outside air enters the lampshade 2 through the air inlet 4 and is then discharged from the air outlet 3. In this process, the heat inside the lampshade 2 is taken away for heat dissipation.

[0043] When the inside of the lampshade 2 is cooled, the cooling motor 7 is started to drive the cooling fan 8 to rotate, and the outside air enters the inside of the lampshade 2 through the air outlet 3, and the heat inside the lampshade 2 is discharged outward through the air outlet 3, so as to achieve efficient heat dissipation of the lampshade 2;

[0044] While the heat dissipation motor 7 is operating, its output shaft drives the transmission assembly 9 to operate synchronously. The operating transmission assembly 9 acts on the first dust removal assembly 10, and the first dust removal assembly 10 acts on the first dustproof net 5, so that the first dustproof net 5 vibrates, and then the dust on the surface of the first dustproof net 5 can be shaken off, ensuring that the heat inside the lampshade 2 is discharged outward through the air outlet 3, which solves the problem in the prior art that a lot of dust will adhere to the surface of the dust cover, thereby affecting the efficiency of heat discharge from the inside of the lighting device and reducing the heat dissipation effect of the lighting device;

[0045] During the operation of the transmission component 9, the second dust removal component 11 is simultaneously acted on, and the second dust removal component 11 acts on the second dustproof net 6, so that the first dustproof net 5 vibrates, and then the dust on the surface of the second dustproof net 6 can be shaken off, so as to prevent the dust from accumulating outside the second dustproof net 6 and affecting the effect of the outside air entering the inside of the lampshade 2 through the air inlet 4, so that the outside air can enter the inside of the lampshade 2 through the air inlet 4, thereby improving the heat dissipation effect of the inside of the lampshade 2;

[0046] As the heat dissipation motor 7 continues to rotate, the transmission component 9 acts on the multiple first dust removal components 10 and the second dust removal components 11 in sequence, thereby effectively shaking off the dust in the first dustproof net 5 and the second dustproof net 6.

[0047] See also Figure 2 and Figure 6 A first annular baffle 12 is fixedly disposed on the outside of the top of the lampshade 2, and the first annular baffle 12 is inclined to receive dust falling from the first dustproof net 5;

[0048] When the first dust removal assembly 10 is in operation, the dust in the first dustproof net 5 will be knocked down to the inside of the first annular baffle 12, thereby preventing the dust from falling downwards and causing inconvenience to the user;

[0049] A second annular baffle 13 is fixedly disposed on the outside of the bottom end of the lampshade 2, and the second annular baffle 13 is arranged in an inclined manner to receive dust dropped from the second dustproof net 6;

[0050] When the second dust removal assembly 11 is in operation, the dust in the second dustproof net 6 will be knocked down to the inside of the second annular baffle 13, thereby preventing the dust from falling downwards and causing inconvenience to the user.

[0051] See also Figure 6-Figure 9, the transmission assembly 9 is composed of an operating member 91 and a toggle member 92;

[0052] The operating member 91 includes a transmission shaft 911, and a first transmission gear 912 and a second transmission gear 913 are fixedly disposed on the top and bottom of the transmission shaft 911, respectively. A third transmission gear 914 is meshed with one side of the first transmission gear 912, and the third transmission gear 914 is fixedly disposed on the outside of the output shaft of the heat dissipation motor 7, and the diameter of the third transmission gear 914 is smaller than that of the first transmission gear 912;

[0053] The toggle member 92 includes a first toggle gear 921 and a second toggle gear 922 which are rotatably arranged inside the lampshade 2. The first transmission gear 912 is meshed with the first toggle gear 921 on one side away from the third transmission gear 914. The second transmission gear 913 is meshed with the second toggle gear 922 on one side. The first toggle gear 921 and the second toggle gear 922 are respectively fixed with a first toggle block 923 and a second toggle block 924 at one end of the top thereof. The second toggle block 924 is made of rubber.

[0054] When the heat dissipation motor 7 drives the heat dissipation fan 8 to rotate, the third transmission gear 914 rotates with the output shaft of the heat dissipation motor 7. Under the meshing action of the third transmission gear 914 and the first transmission gear 912, the first transmission gear 912 drives the transmission shaft 911 and the second transmission gear 913 to rotate, thereby driving the first toggle gear 921 and the second toggle gear 922 to rotate, and the first toggle block 923 and the second toggle block 924 to rotate. In the process of rotation, the first toggle block 923 and the second toggle block 924 act on the first dust removal component 10 and the second dust removal component 11 respectively, the first dust removal component 10 acts on the first dustproof net 5, and the second dust removal component 11 acts on the second dustproof net 6, so as to clean the dust attached to the first dustproof net 5 and the second dustproof net 6;

[0055] By setting up a transmission component 9 composed of an operating member 91 and a toggle member 92, the operating member 91 acts on the toggle member 92 while the heat dissipation motor 7 operates, and the toggle member 92 acts on the first dust removal component 10 and the second dust removal component 11 at the same time, so that the transmission component 9 can operate synchronously with the drive of the heat dissipation motor 7 to activate the first dust removal component 10 and the second dust removal component 11, thereby eliminating the need for a separate power supply to control the first dust removal component 10 and the second dust removal component 11.

[0056] See also Fig.10 The first dust removal assembly 10 includes a first fixing member 101 connected to the inner wall of the lampshade 2, a first vibration rod 102 is rotatably arranged inside the first fixing member 101, and a first spring 103 is arranged between the back side of the first vibration rod 102 and the first fixing member 101;

[0057] As the heat dissipation motor 7 rotates, the first toggle gear 921 drives the first toggle block 923 on its top to rotate. When the first toggle block 923 touches the first vibration rod 102 during the rotation, as the first toggle gear 921 continues to rotate, the first toggle block 923 pushes the first vibration rod 102, and the first vibration rod 102 rotates inside the first fixing member 101. The top of the first vibration rod 102 is away from the first dustproof net 5, and the bottom compresses the first spring 103. When the first toggle block 923 is misaligned with the first vibration rod 102, the first vibration rod 102 2 rotates in the opposite direction under the action of the first spring 103, and its top acts on the first dustproof net 5, so that the dust attached to the surface of the first dustproof net 5 can be shaken off, ensuring the effect of the heat inside the lampshade 2 being discharged outward through the air outlet 3, solving the problem in the prior art that a lot of dust is attached to the surface of the dust cover, thereby affecting the efficiency of heat discharge from the inside of the lighting device and reducing the heat dissipation effect of the lighting device. As the first toggle gear 921 rotates, the first toggle block 923 acts on the multiple first dust removal components 10 in sequence, realizing the effective shaking off of the dust in the first dustproof net 5.

[0059] An L-shaped block 116 is provided at the bottom of the transmission block 115, and an L-shaped ring groove 117 is provided inside the lampshade 2 to match the L-shaped block 116. The L-shaped block 116 matches the L-shaped ring groove 117 to limit the transmission block 115, thereby preventing the transmission block 115 from moving up and down, and ensuring that the positions of the transmission block 115 and the second toggle block 924 always correspond;

[0060] As the heat dissipation motor 7 rotates, the second toggle gear 922 drives the second toggle block 924 on its top to rotate. When the second toggle block 924 touches the transmission block 115 during the rotation, as the second toggle gear 922 continues to rotate, the second toggle block 924 pushes the transmission block 115 and the L-shaped block 116 to slide along the L-shaped ring groove 117. During the movement, the transmission block 115 pulls the second vibration rod 112 away from the second dustproof net 6 through the connecting rope 114, and the second spring 113 is stretched. After the second toggle block 924 moves to a certain angle, since the second toggle block 924 is The second toggle block 924 is made of rubber, so it can be deformed and misaligned with the transmission block 115. The transmission block 115 and the second vibration rod 112 are reset under the action of the second spring 113.

As the second toggle gear 922 rotates, the second toggle block 924 acts on multiple second dust removal components 11 in turn to achieve effective shaking off of dust in the second dustproof net 6.
