Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of glasses cleaning equipment, and particularly relates to an air knife component and a glasses cleaning device comprising the same. Background Art
[0002] Frame glasses typically consist of lenses, frames, nose bridges, nose pads, temples, and other major components. They are categorized into three types: full-frame, half-frame, and rimless. Frame glasses generally need to be cleaned after one or two days of wearing to keep them bright and clear, and maintain a clean and fresh appearance. Existing ultrasonic eyeglass cleaning machines require a certain amount of cleaning solution to be added to the cleaning tank before placing the frame glasses. After the ultrasonic cleaning is complete, the glasses must be manually removed from the cleaning solution. This results in wet hands, and the glasses must then be dried, making the entire process rather cumbersome.
[0003] Compared to smooth lenses, temples often have intricate shapes, some with hollowed-out or embossed patterns. Water droplets trapped in the grooves on the temples and at the corners where they connect to the frame are difficult to wipe away and are difficult to remove with unidirectional wind. Especially in winter, when cold water droplets come into contact with warm ear skin, they can create an uncomfortable, chilly sensation. Furthermore, frequent wiping with paper towels consumes considerable time and tissues, and because temples are often made of a soft, scratch-resistant material, they can easily leave scratches on the surface.

The downward oblique airflow sent by the second air knife can also cover the water droplets on the inner surface of the temple, pushing the water droplets on the inner surface of the temple downward and reducing the water droplets. The downward oblique airflow also causes the water droplets that were pushed by the first air knife to the inner corners of the lower surface of the temple to be separated from the temple.
[0024] Through the cooperation of the first wind knife and the second wind knife, the drying airflow covers the inner and outer surfaces of the temples, especially pushing the water droplets in the grooves and the corners where the temples and frames are connected.

DETAILED DESCRIPTION
[0035] The present invention will be described in further detail below in conjunction with the embodiments and with reference to the accompanying drawings. Example 1
[0036] One embodiment of the present invention is an air knife assembly for air-drying the temples of framed glasses. Figure 1 and Figure 2 The air knife assembly of this embodiment includes a first air knife and a second air knife.
[0037] The first air knife includes a first air knife inlet, a first air knife hollow duct, and a first air knife outlet. One end of the first air knife inlet is connected to an external air source, and the other end is connected to one end of the first air knife hollow duct; the other end of the first air knife hollow duct is connected to the first air knife outlet. The second air knife includes a second air knife inlet, a second air knife hollow duct, and a second air knife outlet. One end of the second air knife inlet is connected to an external air source, and the other end is connected to one end of the second air knife hollow duct; the other end of the second air knife hollow duct is connected to the second air knife outlet.
[0038] The air source is a fan. Use two fans to connect the first air knife inlet and the second air knife inlet respectively, such as Figure 2 shown.
[0039] The frame glasses to be air-dried are placed with the temples spread out. The first air knife outlet portion is opposite to the second air knife outlet portion and is respectively arranged obliquely below and obliquely above the temples.
[0040] like Figure 3 and Figure 4 As shown, the first air knife outlet portion includes a first air knife outlet and a first curved bend connected to the first air knife hollow pipe. The first curved bend is hook-shaped, so that the airflow entering the first air knife hollow pipe from top to bottom passes through the first curved bend and is sent out from the first air knife outlet in an obliquely upward direction.
[0041] The first air knife air outlet is arranged at the end of the first air knife. The first air knife hollow pipe is connected to the first air knife air outlet through a first arc-shaped bend where the cross section changes.
[0042] Preferably, the first air knife outlet is a rectangular groove, and the long side length of the rectangular groove of the first air knife outlet is greater than the diameter of the first air knife hollow pipe, so that the airflow sent out from the first air knife outlet covers the temples of the glasses to be dried.
[0043] Preferably, the cross-sectional area of the first air knife air outlet is smaller than the cross-sectional area of the first air knife air inlet, so that the airflow entering the first air knife is accelerated and sent out from the first air knife air outlet.
[0044] The first deformed rib is formed by obliquely cutting from the tangent line where the first arc bend intersects the two sides of the first air knife outlet to the side of the first arc bend, and the angle α between the center line of the first deformed rib and the axis of the first air knife hollow pipe is an acute angle.
[0045] Taking the first wind knife set on the outside of the temple of the frame glasses as an example, the airflow output by the wind source enters the first wind knife hollow pipe from the first wind knife air inlet, and is guided by the first wind knife air outlet, and an upward oblique airflow is sent from the first wind knife air outlet to the surface of the temple of the frame glasses to be dried. The airflow can cover the water droplets on the outer surface and lower surface of the temple, push the water droplets on the outer surface of the temple to move, and make the water droplets smaller. The water droplets evaporate due to the drive of the airflow, and push the water droplets hanging on the lower surface of the temple to move to the inner side (or outer surface) of the temple, thereby quickly drying the surface of the temple of the frame glasses.
[0046] like Figure 5 and Figure 6 As shown, the second air knife outlet portion includes a second air knife outlet and a second arc bend connected to the second air knife hollow pipe.
[0047] The second air knife outlet is located at the end of the second air knife. The second air knife hollow pipe is connected to the second air knife outlet through a curved bend, where the cross-section changes. The second curved bend allows airflow entering the second air knife hollow pipe from top to bottom to pass through the second curved bend and then be delivered obliquely downward from the second air knife outlet.
[0048] Preferably, the second air knife outlet is a rectangular slot, and the length of the longer side of the rectangular slot is greater than the diameter of the second air knife hollow tube, so that the airflow from the second air knife outlet covers the temples of the glasses to be dried. The cross-sectional area of the second air knife outlet is smaller than the cross-sectional area of the second air knife inlet, so that the airflow entering the second air knife is accelerated and discharged from the second air knife outlet.
[0049] The second deformed rib is formed by obliquely cutting from the tangent line where the second arc bend intersects the two sides of the second air knife outlet to the side of the second arc bend, and the angle β between the center line of the second deformed rib and the axis of the second air knife hollow pipe is an acute angle.
[0050] Preferably, the distance between the two long side surfaces of the first wind knife air outlet is 1.6-8.5mm, and the distance between the two long side surfaces of the second wind knife air outlet is 2.3-12.1mm. The cross-sectional area of the first wind knife air outlet is 35%-89% of the cross-sectional area of the first wind knife air inlet, and the cross-sectional area of the second wind knife air outlet is 27%-73% of the cross-sectional area of the second wind knife air inlet. The distance between the intersection of the first arc bend and the first wind knife air outlet and the edge of the first wind knife air outlet is no more than 8mm; the distance between the intersection of the second arc bend and the second wind knife air outlet and the edge of the second wind knife air outlet is no more than 5mm. The range of α is 21°-68°, and the range of β is 11°-42°.
[0051] Taking the example of a first wind knife being arranged on the outside of the temple of the frame glasses and a second wind knife being arranged on the inside of the temple of the frame glasses, the airflow output by the wind source enters the second wind knife hollow pipe from the second wind knife air inlet, is guided through the second wind knife air outlet, and is sent out from the second wind knife air outlet to the surface of the temple of the frame glasses to be air-dried. This airflow can cover the water droplets on the upper surface of the temple, and push the water droplets on the upper surface of the temple to move toward the outside of the temple. This airflow, together with the oblique upward airflow sent out by the first wind knife, accelerates the evaporation of the water droplets at the corners of the upper surface of the temple. The oblique downward airflow sent out by the second wind knife can also cover the water droplets on the inner surface of the temple, and push the water droplets on the inner surface of the temple to move downward and make the water droplets smaller. The oblique downward airflow causes the water droplets that are pushed by the first wind knife and deflected to the inner corners of the lower surface of the temple to separate from the temple, especially the water droplets that are blocked at the tip of the temple where the temple intersects the glasses frame to move away. The two airflows of the first wind knife and the second wind knife accelerate evaporation, and the surface of the temple of the frame glasses is quickly air-dried. Example 2
[0052] Another embodiment of the present invention is different from the embodiment 1 in that a fan is used to connect the first air knife air inlet and the second air knife air inlet, such as Figure 7 shown.
[0053] The air inlet portion and the hollow pipe may be formed integrally, or alternatively, the air inlet portion may be an independent component attached to the hollow pipe. Example 3
[0054] Another embodiment of the present invention, as Figure 8 and Figure 9 As shown, the difference from Example 1 is that the first wind knife hollow pipe is arranged horizontally, and the airflow entering the first wind knife hollow pipe is sent out from the first wind knife air outlet after being bent in the first arc shape; the second wind knife hollow pipe is arranged vertically, and the airflow entering the second wind knife hollow pipe is sent out from the second wind knife air outlet after being bent in the second arc shape.
[0055] Preferably, the glasses cleaning device can use at least one air knife assembly of the present invention to air dry the inner and outer surfaces of the frame glasses.
[0056] The wind knife assembly of the utility model is characterized in that when the first wind knife and the second wind knife are respectively arranged on the outer side and the inner side of the temple of the frame glasses to be air-dried, the first wind knife sends an oblique upward airflow to the temple. The airflow can cover the water droplets on the outer surface and the lower surface of the temple, push the water droplets on the outer surface of the temple to move, and make the water droplets smaller. The water droplets evaporate due to the drive of the airflow, and push the water droplets hanging on the lower surface of the temple to move toward the inner side of the temple.
[0057] The second air knife sends a downward oblique airflow to the temple of the frame glasses to be dried. This airflow can cover the water droplets on the upper surface of the temple, pushing the water droplets on the upper surface of the temple to move to the outside of the temple. This airflow, together with the upward oblique airflow sent by the first air knife, accelerates the evaporation of water droplets at the corners of the upper surface of the temple. The downward oblique airflow sent by the second air knife can also cover the water droplets on the inner surface of the temple, pushing the water droplets on the inner surface of the temple downward and reducing the water droplets. The downward oblique airflow also causes the water droplets that were pushed by the first air knife to the inner corners of the lower surface of the temple to be separated from the temple.
[0058] Through the cooperation of the first wind knife and the second wind knife, the drying airflow covers the inner and outer surfaces of the temples, especially pushing the water droplets in the grooves and the corners where the temples and frames are connected. The double airflow accelerates evaporation and dries quickly, saving the manual wiping process, saving paper towels, and protecting trees and the environment.
[0059] Although the present invention has been disclosed above with reference to preferred embodiments, these embodiments are not intended to limit the present invention. Any equivalent variations or modifications made without departing from the spirit and scope of the present invention are also within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the content defined by the claims of this application.
