However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details that hinder the description of the present invention.

[0043] Please refer to Figures 1 to 10 The present application provides a contact-free automatic cleaning device, including a housing 10, a bottle holder 20 and a cleaning component 30.

[0044] Specifically, a storage space is defined inside the housing 10, and a delivery pipeline for delivering cleaning liquid is provided in the storage space. The bottle holder 20 is embedded in the housing 10, and a first placement cavity 21, a second placement cavity 22, and a third placement cavity 23 are formed on the bottle holder 20, which are arranged side by side and used to place different cleaning bottles 50. A plug-in tube is provided in the first placement cavity 21, the second placement cavity 22, and the third placement cavity 23, and the plug-in tube is connected to the delivery pipeline. The cleaning assembly 30 includes a shell 31, a clamping unit 33, a flushing tube 34, and a sound wave generator 32. A storage cavity is defined inside the shell 31, and a sound wave hole 31a connected to the storage cavity is provided on one side of the shell 31. The sound wave generator 32 is installed on the outside of the shell 31 and is opposite to the sound wave hole 31a, and is used to generate sound waves to be transmitted from the sound wave hole 31a to the storage cavity;

[0045] It also includes a germicidal lamp, which is arranged in the accommodating cavity so that the light emitted by the germicidal lamp can irradiate the lens in the fixture 332.

[0046] Exemplarily, the sound wave generator 32 is used to generate sound waves so that the generated sound waves can be used to act on the lens of the fixture 332, thereby achieving the purpose of cleaning. In addition, it should be noted that the sound wave generator 32 can be an ultrasonic oscillator or a megasonic oscillator. Since the operating frequency of the ultrasonic oscillator is between 20kHz and 100kHz; and the operating frequency of the megasonic oscillator is above 1MHz. The amplitude of the ultrasonic oscillator is generally at the micron level or nanometer level; and the amplitude of the megasonic oscillator is smaller and can reach below the nanometer level. Since the megasonic oscillator has a smaller amplitude, its energy density is higher and has stronger penetration, so the cleaning effect will be better. For this reason, in the present embodiment, the sound wave generator 32 selects a megasonic generator 32.

[0047] Exemplarily, the power source 331 may be a motor, or a power component commonly used for driving in the prior art, which is not limited thereto.

[0048] Illustratively, the provision of a germicidal lamp can utilize the emitted light to sterilize the clamped lens, which is beneficial to improving the cleaning effect of the lens.

[0049] Exemplarily, the first placement cavity 21, the second placement cavity 22 and the third placement cavity 23 formed side by side on the bottle holder 20 are for installing the cleaning bottles 50 filled with different cleaning solutions, and can be set accordingly according to different cleaning steps. For example, the cleaning of the lens is divided into the steps of disinfection-cleaning-care, specifically: inserting the mouths of the first bottle, the second bottle and the third bottle filled with disinfectant, saline and care solution into the first placement cavity 21, the second placement cavity 22 and the third placement cavity 23, and then controlling the outflow of the disinfectant, saline and care solution in turn.

[0050] Based on the contactless automatic cleaning device with the above technical features, the mouths of the cleaning bottles 50 filled with different cleaning liquids are respectively loaded into the first placement cavity 21, the second placement cavity 22 and the third placement cavity 23, and the plug-in tube is inserted into the bottle of the cleaning bottle 50, so that the cleaning liquid in the cleaning bottle 50 is sequentially transported to the flushing tube 34, and then the flushing tube 34 is used to spray the cleaning liquid onto the lens clamped on the fixture 332, and the power source 331 is used to drive the fixture 332 to rotate, so as to realize cleaning of various positions of the lens, ensuring that the cleaning is more comprehensive and clean, and then the sound waves emitted by the sound wave generator 32 act on the lens, which can further enhance the cleaning effect of the lens, and has a simple structure, convenient operation and better cleaning effect.

[0051] Among them, the clamping unit 33 includes a power source 331 and a clamp 332 arranged in the storage cavity, the clamp 332 is used to clamp the lens to be cleaned, the power source 331 is fixed to the outside of the shell 31, and the output end of the power source 331 is connected to the clamp 332, one end of the flushing tube 34 is connected to one end of the conveying pipeline, and the other end of the flushing tube 34 passes through the shell 31 and extends into the storage cavity, and faces the clamping assembly.

[0052] In a possible implementation, the clamp 332 includes a fixed seat 3321 and at least one clamp body 3322, and the clamp body 3322 is fixed on the surface of the fixed seat 3321 facing the power source 331. The clamp body 3322 includes a first elastic arm 33221 and a second elastic arm 33222 connected to each other, a clamping space is defined between the first elastic arm 33221 and the second elastic arm 33222, a first slide groove 33221a along the vertical direction is provided on the side of the first elastic arm 33221 facing the second elastic arm 33222, a second slide groove 33222b along the vertical direction is provided on the side of the second elastic arm 33222 facing the first elastic arm 33221, a first opening 33221b communicating with the first slide groove 33221a is provided on the outer side of the first elastic arm 33221, and a second opening 33222a communicating with the second slide groove 33222b is provided on the outer side of the second elastic arm 33222. After both side edges of the lens slide into the clamping space along the first slide groove 33221a and the second slide groove 33222b, the first elastic arm 33221 and the second elastic arm 33222 clamp and fix the lens, and both side edges of the lens extend from the first opening 33221b and the second opening 33222a respectively.

[0053] It should be noted that the "at least one clamping body 3322" mentioned above refers to one or more than one, and can be specifically set according to the needs of cleaning. For example, if there are two lenses to be cleaned (i.e., a pair of lenses), two spaced-apart clamping bodies 3322 are set on the fixing seat 3321, so that the two lenses are placed on the fixing seat 3321 respectively, so that two lenses can be cleaned at one time, which is conducive to improving the cleaning efficiency.

[0054] Exemplarily, a plurality of clamping bodies 3322 are distributed on the fixing seat 3321, and each clamping body 3322 is composed of a first elastic arm 33221 and a second elastic arm 33222 which are connected to form a clamping space between the first elastic arm 33221 and the second elastic arm 33222. When the lens needs to be cleaned, the lens is slid from top to bottom along the direction of the first slide groove 33221a and the second slide groove 33222b into the clamping space. At this time, the two side edges of the lens extend from the first opening 33221b and the second opening 33222a respectively, so that the lens is clamped and fixed under the joint action of the first elastic arm 33221 and the second elastic arm 33222, which is convenient for subsequent cleaning of the lens and can effectively prevent the lens from falling during the cleaning process. At the same time, since the first elastic arm 33221 and the second elastic arm 33222 are elastic, they can be suitable for clamping lenses of different sizes and have a wide range of applications.

[0055] In a possible implementation, an upwardly protruding block 90 is provided on the fixing seat 3321, the lower parts of the first elastic arm 33221 and the second elastic arm 33222 are connected by a connecting strip 333, and the first elastic arm 33221, the second elastic arm 33222 and the connecting strip 333 together form a bayonet 334 that is clamped with the block 90.

[0056] Exemplarily, the lower parts of the first elastic arm 33221 and the second elastic arm 33222 are connected by the connecting strip 333 so that the first elastic arm 33221 and the second elastic arm 33222 form a whole, which can effectively enhance the strength of the clamp 332 and avoid damage to the clamp 332 during the process of clamping the lens, thereby affecting normal clamping.

[0057] In addition, an upward protrusion is provided on the fixing seat 3321, and the first elastic arm 33221, the second elastic arm 33222 and the connecting strip 333 together form a bayonet 334 so that the protrusion can be inserted into the bayonet 334, thereby realizing the detachable connection of the clamp 332 to the fixing seat 3321, which has a simple structure and is easy to disassemble and assemble.

[0058] In a possible embodiment, it also includes a bottle mouth connector 60 for connecting the cleaning bottle 50, and the inner walls of the first placement cavity 21, the second placement cavity 22 and the third placement cavity 23 are provided with limit blocks 20a, and the outer surface of the end of the bottle mouth connector 60 connected to the bottle seat 20 is provided with a limit groove 60a; wherein, when the bottle mouth connector 60 is connected to the first placement cavity 21, the second placement cavity 22 or the third placement cavity 23, the limit block 20a is inserted into the limit groove 60a, so that the bottle mouth connector 60 can be detachably connected to the bottle seat 20.

[0059] For example, the bottle mouth connector 60 is detachably connected in the first placement cavity 21, the second placement cavity 22 and the third placement cavity 23, and then the bottle mouth of the cleaning bottle 50 is connected to the bottle mouth connector 60, so that the cleaning bottle 50 is fixed on the fixing seat 3321 for use. It should be noted that since the bottle mouth connector 60 is detachably installed in the first placement cavity 21, the second placement cavity 22 and the third placement cavity 23, the bottle mouth connector 60 that is compatible with the bottle mouth can be selected according to the size of the cleaning bottle 50, so that the cleaning bottles 50 of various sizes can be adapted, and the use range is wider.

[0060] In a possible embodiment, it also includes a waste liquid bottle 70 and a drain pipe 35. A placement groove is opened on the housing 10. The waste liquid bottle 70 can be detachably placed in the placement groove. One end of the drain pipe 35 is connected to the storage cavity, and the other end of the drain pipe 35 is connected to the waste liquid pipe. A flip cover 80 is flipped on one side of the placement groove, and the flip cover 80 is used to confine the waste liquid bottle 70 in the placement groove.

[0061] Exemplarily, by placing the waste liquid bottle 70 in the placement groove, and then using the flip cover 80 to restrict the waste liquid bottle 70, so that the drain bottle is fixed in the placement groove, and then the waste liquid in the storage cavity is introduced into the waste liquid bottle 70 through the drain pipe 35. After the waste liquid bottle 70 is filled with waste liquid, the flip cover 80 is flipped up. At this time, the flip cover 80 is freed from the restriction on the waste liquid bottle 70, and then the drain bottle is taken out of the placement groove, the waste liquid bottle 70 can be disassembled. The structure is simple, which is convenient for the subsequent treatment of the waste liquid in the waste liquid bottle 70.

When the pressing rod 41 is alternately squeezed, the air pressure in the cavity alternately changes between the first state and the second state, so that the suction cup 43 alternately generates suction to adsorb the lens.

[0063] Exemplarily, by integrally connecting a mounting column to the top of the suction cup 43, and setting a plug-in cavity inside the mounting column, the plug-in column of the suction cup 43 rod 42 is then inserted into the plug-in cavity so that the suction cup 43 can be detachably mounted on the suction cup 43 rod 42. The structure is simple and convenient for subsequent rapid replacement of the suction cup 43.

[0064] In a possible embodiment, the end of the sucker 43 rod 42 away from the pressing rod 41 has a hollow plug-in column, the top of the sucker 43 is integrally connected to the mounting column, and the mounting column is provided with a plug-in cavity for plugging with the plug-in column. In this way, by integrally connecting the mounting column to the top of the sucker 43, and providing the plug-in cavity inside the mounting column, and then inserting the plug-in column of the sucker 43 rod 42 into the plug-in cavity, the sucker 43 can be detachably mounted on the sucker 43 rod 42, which has a simple structure and facilitates the subsequent rapid replacement of the sucker 43.
