[0029] Embodiment 1:

[0030] See also Figure 1-4 The present embodiment provides a mask cleaning device based on ultrasonic decontamination technology, including an ultrasonic cleaning mechanism 1 and a filtering circulation mechanism 2, wherein the ultrasonic cleaning mechanism 1 is connected to the filtering circulation mechanism 2; the ultrasonic cleaning mechanism 1 includes a cleaning tank 11, a fixed grid 12, a plurality of ultrasonic vibrators 13 and an ultrasonic generating assembly 14; the fixed grid 12 is arranged in the cleaning tank 11, and a plurality of array-arranged ultrasonic vibrators 13 are arranged on one side of the cleaning tank 11, and the ultrasonic vibrators 13 are connected to the ultrasonic generating assembly 14, and the ultrasonic generating assembly 14 is arranged on one side of the cleaning tank 11; the filtering circulation mechanism 2 includes a plurality of filtering assemblies connected in sequence, and the cleaning water in the cleaning tank 11 is filtered through the plurality of filtering assemblies connected in sequence and then returned to the cleaning tank 11.

[0031] In this embodiment, the ultrasonic cleaning mechanism 1 is used to clean the mask, and the filtering and circulating mechanism 2 circulates and filters the cleaning water in the ultrasonic cleaning mechanism 1 so that the cleaning water can be recycled to ensure that the cleaning requirements are met. Among them, the cleaning tank 11 is used to install a number of ultrasonic vibrators 13 on the outside and to accommodate cleaning water; the fixed frame 12 is used to place the mask to prevent the mask from directly contacting the tank wall of the cleaning tank 11 during ultrasonic cleaning and causing damage to the mask, and to fix the mask during cleaning to prevent its parts from falling off; the ultrasonic vibrator 13 and the ultrasonic generating component 14 are used to cooperate with each other, the ultrasonic generating component 14 converts electrical energy into a high-frequency alternating current signal matching the ultrasonic vibrator 13 and is connected to the ultrasonic vibrator 13, and the generated ultrasonic wave is converted by the ultrasonic vibrator 13 into a high-frequency vibration wave and then transmitted to the cleaning water in the cleaning tank 11 to clean the protective mask, and then the mask is cleaned by ultrasonic decontamination technology; a number of filter components connected in sequence are used to filter the cleaning water multiple times to achieve cyclic cleaning of the cleaning water, and then continuously purify residual stains, reduce residual stains in the cleaning water, further improve the cleaning effect, and finally achieve lossless and efficient cleaning of the mask and reuse of the mask.

[0032] Ultrasonic decontamination technology uses penetrating cavitation shock waves generated when sound waves propagate in a medium to transfer energy. When ultrasonic waves pass through a liquid medium, they will compress the liquid medium to vibrate at an extremely high frequency, causing shock waves to be generated in the liquid molecules. When the sound intensity reaches a certain value, tiny cavitation bubbles grow rapidly in the liquid and close instantly and strongly, generating strong micro-explosions and shock waves that destroy the dirt on the surface of the object being cleaned and fall off the surface being cleaned. Therefore, by utilizing the direct and indirect effects of ultrasonic cavitation, acceleration and straight-forward flow in the liquid on the liquid and dirt, the dirt layer of the mask is dispersed, emulsified and peeled off to achieve the purpose of cleaning. It can effectively remove the dirt and odor residues formed by repeated use of full masks, improve the obstruction of vision, and reduce the risk of affecting work safety.

[0033] In this embodiment, there are multiple ways to fix the ultrasonic vibrator 13 to the outside of the cleaning tank 11, including but not limited to, a plurality of vibrator mounting grooves are provided on the outer wall of the cleaning tank 11 corresponding to the arrangement of the plurality of ultrasonic vibrators 13, and the ultrasonic vibrator 13 is installed and fixed on the cleaning tank 11 through the vibrator mounting grooves.

[0034] In one example of this embodiment, in order to further achieve the cleaning of multiple masks, as shown in the attached Figure 2 As shown, a plurality of partition grooves 121 are provided in the fixed grid 12. One or more masks can be placed in each partition groove 121 to achieve the effect of cleaning a large number of masks at the same time, thereby improving the efficiency of mask cleaning. For example, since the mask in the radiation control area is composed of a face screen, a fixed headband, an oral and nasal sealing mask, a sealing gasket, a filter box, etc. In order to effectively prevent the seal of the mask from falling off and floating away, and shorten the manpower operation time required after the full mask is cleaned. In this embodiment, the fixed grid 12 is divided into nine grids, that is, nine partition grooves 121, and the full mask is placed in the partition groove 121 with two to three grids per grid, wherein the oral and nasal sealing mask assembly is attached to the inner wall of the grid, and is prevented from falling off and floating out by squeezing.

[0035] In this embodiment, as shown in the attached Figure 2 As shown, the fixed grid 12 and the separation groove 121 are both provided with a plurality of through holes 122. The function of the through holes 122 is to allow the cleaning water to enter the groove and contact the mask to achieve ultrasonic cleaning.

[0036] In one example of this embodiment, the fixing method of the fixed frame 12 in the cleaning tank 11 is as follows: Figure 4As shown, a plurality of support members 111 are provided at the bottom of the cleaning tank 11, and the fixed grid 12 is placed on the support members 111. A limiting structure can also be provided on the support members 111 to further limit the fixed grid 12 to prevent it from being displaced during ultrasonic vibration. It should be noted that, in the present embodiment, the fixing method of the fixed grid 12 in the cleaning tank 11 is not limited to the above method, and it can also be, for example, a hook-shaped member is provided on the top of the fixed grid 12, and the hook-shaped member can be hung on the top of the cleaning tank 11, thereby achieving installation and fixation. Furthermore, a handle 123 is also provided on the top of the fixed grid 12, and the handle 123 is convenient for placing the fixed grid 12 into the cleaning tank 11 and taking the fixed grid 12 out of the cleaning tank 11 when in use, so as to facilitate use.

[0037] In one example of this embodiment, a heating component (not shown in the figure) is provided in the cleaning tank 11, and the heating component is provided on the inner wall of the cleaning tank 11. By heating the cleaning water by the heating component, the decontamination efficiency can be further improved.

[0038] In this embodiment, preferably, a plurality of ultrasonic vibrators 13 arranged in an array are simultaneously provided on the bottom surface and at least one side surface of the cleaning tank 11 .

[0039] In this embodiment, the ultrasonic cleaning mechanism 1 is provided with a shell 3 covering the ultrasonic cleaning mechanism 1, and the shell 3 can protect the internal structure of the ultrasonic cleaning mechanism 1. The shell 3 is provided with an opening 31 at the top position corresponding to the cleaning tank 11, and a cover 32 is provided on the opening 31, and a cover handle 321 is provided on the cover 32. Thus, the airtightness of the cleaning environment and the convenience of use are ensured.

[0040] In this embodiment, as shown in the attached Figure 3 As shown, the mask cleaning device also includes a control mechanism 4, which is respectively connected to the ultrasonic generating component 14 and the heating component, and is used to control the start and stop of the ultrasonic generating component 14, and is used to control the start and stop of the heating component, and is used to control the start and stop of the heating component.

The control panel is connected to the control knob. The control panel is arranged on the inner side of the shell 3, and the control knob is arranged on the outer side of the shell 3.

[0042] Among them, the control panel is provided with a circuit structure and control elements for realizing adjustment control. The circuit structure and control elements for realizing adjustment control can adopt the existing technology and will not be described in detail here.

[0043] Among them, the control knob for controlling the ultrasonic generating component 14 can be used to adjust the power of the ultrasonic generating component 14, so that the ultrasonic generating component 14 adjusts the ultrasonic intensity generated by the ultrasonic vibrator 13 according to the power to adjust the cleaning efficiency of the mask. When the ultrasonic intensity increases, the ratio of the maximum radius of the cavitation bubble to the starting radius increases, and the cavitation intensity increases, that is, the higher the sound intensity, the stronger the cavitation, which is conducive to the ultrasonic cleaning effect. However, the higher the ultrasonic sound power, the better. If the sound intensity is too high, a large number of useless bubbles will be generated, which will increase the scattering attenuation and form a sound barrier. At the same time, the increase in sound intensity will also increase the nonlinear attenuation, which will weaken the cleaning effect far away from the sound source. In this embodiment, preferably, the power of the mask cleaning is 2 to 3KW.

[0044] Among them, the control knob for controlling the heating component can be used to control the temperature of the heating component, thereby controlling the decontamination efficiency.

[0045] In addition, in this embodiment, the control knob may also be replaced by a touch screen or a button.

[0046] In this embodiment, preferably, the ultrasonic generating component 14 is an ultrasonic generator.

In this embodiment, four filtering components are provided to perform quadruple filtration on the cleaning water, and multiple purifications are performed to form a water circulation filtration system, thereby ensuring the clean water quality and preventing pollutants from reattaching to the mask.

[0049] The specific structure of the first filter assembly 21 is further described as shown in the attached Figure 5 As shown, the first filter assembly 21 includes an overflow pipe 211 and a filter bag (not shown in the figure); one end of the overflow pipe 211 is connected to the high overflow port 112 or the low overflow port 113 of the cleaning tank 11, and the other end of the overflow pipe 211 extends into the second filter assembly 22, and a filter bag is provided at the other end of the cleaning tank 11.

[0050] Among them, the water of the cleaning tank 11 is discharged through the high overflow port 112 or the low overflow port 113, and the sewage flows from the overflow port and the pipeline into the second filter assembly 22 through the filter bag. The filter bag is set at the connection between the overflow pipe 211 and the second filter assembly 22. The filtration accuracy is related to the specifications of the filter bag.
