[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Please refer to Figures 1 to 5 , an embodiment provided by the present invention: A special cleaning device for fruits and vegetables, including the main body 1 of the bubble cleaning device. One side of the lower end surface of the main body 1 of the bubble cleaning device is installed at the water source delivery port 2. The middle position of the lower end surface of the water source delivery port 2 is fixedly connected with an external thread connecting pipe 5. The lower side of the outer surface of the external thread connecting pipe 5 is connected with an internal thread sealing sleeve 6 through a threaded structure. The lower side inside the internal thread sealing sleeve 6 is provided with an L-shaped connecting water pipe 7 that fits its inner wall. The middle position of the upper end surface of the L-shaped connecting water pipe 7 is provided with a placing groove 8. The inside of the placing groove 8 contains a coarse hole metal filter net 12, and a plurality of filter nets 11 are arranged below the coarse hole metal filter net 12;

[0029] The front end surface of the L-shaped connecting water pipe 7 is connected with a circulation water pump 3. One side of the upper end surface of the circulation water pump 3 is connected with a return pipe 4, and the upper end surface of the return pipe 4 is connected to the lower end surface of the main body 1 of the bubble cleaning device.

[0030] One side of the outer surface of the main body 1 of the bubble cleaning device is fixedly installed with a control panel, and both the main body 1 of the bubble cleaning device and the circulation water pump 3 are electrically connected to the main body 1 of the bubble cleaning device; the main body 1 of the bubble cleaning device and the circulation water pump 3 can be controlled through the control panel;

[0031] When it is necessary to add a water source inside the device, the water source located inside the main body 1 of the bubble cleaning device will enter the inside of the external thread connecting pipe 5 through the water source delivery port 2 installed on the lower end surface of the main body 1 of the bubble cleaning device. The water source flowing out of the external thread connecting pipe 5 will enter the inside of the placement groove 8 located on the upper end surface of the L-shaped connecting water pipe 7, and pass through between the coarse-hole metal filter screen 12 and the multiple filter screens 11 located inside the placement groove 8. The coarse-hole metal filter screen 12 located at the top can block the fruit and vegetable fragments mixed in the water source, and the multiple filter screens 11 located below the coarse-hole metal filter screen 12 can adsorb the pesticides mixed in the water source during the cleaning process. Through the above technical solution, during the use of the device, the water source located inside the device can be continuously purified, so as to ensure that the cleaning effect of the device will not be affected by pesticides or fruit and vegetable fragments;

[0032] The water source that enters the inside of the L-shaped connecting water pipe 7 will finally flow into the inside of the circulation water pump 3 connected to the L-shaped connecting water pipe 7, and through the circulation water pump 3, this water source can be re-injected into the inside of the main body 1 of the bubble cleaning device through the return pipe 4 for recycling.

[0033] A fixing box 9 is provided on the outer side of the coarse-hole metal filter net 12. The coarse-hole metal filter net 12 and multiple filter nets 11 are both located inside the fixing box 9. The outer surface of the fixing box 9 is fitted with the inner wall of the placement groove 8, and the fixing box 9 is slidably connected to the placement groove 8. At the middle position of the upper end surface of the fixing box 9, an external-thread fixing ring 13 is connected through a threaded structure. At the middle position of the upper end surface of the external-thread fixing ring 13, a second circular through-hole 14 is provided. Below the second circular through-hole 14, a first circular through-hole 10 is provided at the middle position of the lower end surface of the fixing box 9. Above the second circular through-hole 14, a rotating handle 16 fixed to the upper end surface of the external-thread fixing ring 13 is provided, and the external-thread fixing ring 13 and the rotating handle 16 are fixed by screws. When the work of a day is over, manually rotate the internal-thread sealing sleeve 6. Driven by the threaded structure, the rotating internal-thread sealing sleeve 6 can move up and down. At this time, move the internal-thread sealing sleeve 6 upward. As the internal-thread sealing sleeve 6 rises, the top end of the L-shaped connecting water pipe 7 will gradually be exposed to the outside. When the internal-thread sealing sleeve 6 can no longer be moved upward, take out the fixing box 9 containing the coarse-hole metal filter net 12 and the filter nets 11 from the inside of the placement groove 8 through the rotating handle 16 and the external-thread fixing ring 13 which is connected to the fixing box 9 through a threaded structure. After the fixing box 9 is taken out, rotate the external-thread fixing ring 13 through the rotating handle 16. Driven by the threaded structure, the rotating external-thread fixing ring 13 can move up and down. At this time, move the external-thread fixing ring 13 upward to remove it. After the external-thread fixing ring 13 is removed, the coarse-hole metal filter net 12 and the filter nets 11 located inside the fixing box 9 can be directly poured out. After the coarse-hole metal filter net 12 and the filter nets 11 located inside the fixing box 9 are poured out, add new coarse-hole metal filter net 12 and filter nets 11 to it, and reinstall the external-thread fixing ring 13 on the upper end surface of the fixing box 9. After the external-thread fixing ring 13 is installed, place the fixing box 9 back to its original position, and manually rotate the internal-thread sealing sleeve 6 again. At this time, move the internal-thread sealing sleeve 6 downward to seal the fixing box 9 located inside the placement groove 8. Through the above technical solution, the coarse-hole metal filter net 12 and the filter nets 11 can be quickly replaced, so as to improve the convenience of the equipment.

[0034] Above the fixing box 9, a pressing ring 15 fixed to the inner wall of the internal-thread sealing sleeve 6 is provided. The lower end surface of the pressing ring 15 is fitted with the upper end surface of the fixing box 9. During the downward movement of the internal-thread sealing sleeve 6, the pressing ring 15 fixed to its inner wall will move downward together. When the lower end surface of the pressing ring 15 is fitted with the upper end surface of the fixing box 9, the fixing box 9 can be fixed. By fixing the fixing box 9, the stability of the fixing box 9 can be ensured, and it can be prevented from being displaced due to the flow of water.

[0035] A circulating immersion mechanism is installed on the upper end surface of the main body 1 of the bubble cleaning device. The circulating immersion mechanism includes a circulating lifting mechanism, a lower pressing plate 24, and two inclined side plates 27. The two inclined side plates 27 are respectively fixed to the front and rear end faces of the lower pressing plate 24. A plurality of through holes 25 are provided on the lower end faces of the lower pressing plate 24 and the two inclined side plates 27. And on one side of the through holes 25 located on the lower end face of the lower pressing plate 24, there is an arc-shaped groove 26 also located on the lower end face of the lower pressing plate 24. The circulating lifting mechanism can drive a lower pressing plate 24 and two inclined side plates 27 to move up and down cyclically.

[0036] The circulating lifting mechanism includes a metal housing 17. On one side inside the metal housing 17, a stepping motor 18 is fixedly installed. The output shaft of the stepping motor 18 is connected to a concave-shaped rotating shaft 19 through a coupling. The front end of the concave-shaped rotating shaft 19 is located inside the metal housing 17, and the concave-shaped rotating shaft 19 is connected to the metal housing 17 through a roller bearing. When there are fruits and vegetables floating on the outer surface of the water source inside the device, start the stepping motor 18, and the connected concave-shaped rotating shaft 19 can be driven to rotate through the stepping motor 18.

[0037] The shape at the middle position of the concave-shaped rotating shaft 19 is concave. A metal sleeve 20 is movably sleeved at the middle position of the concave position on the outer surface of the concave-shaped rotating shaft 19. The lower end face of the metal sleeve 20 is connected to a first push rod 21 through a rotating shaft. The lower end face of the first push rod 21 is connected to a second push rod 22 through a rotating shaft, and the lower end face of the second push rod 22 is connected to the lower pressing plate 24. As the concave-shaped rotating shaft 19 rotates, the metal sleeve 20 movably sleeved on the outer surface of the concave-shaped rotating shaft 19 will revolve around the connection point between the concave-shaped rotating shaft 19 and the stepping motor 18.

[0038] A guide sleeve 23 is movably sleeved on the lower side of the outer surface of the second push rod 22. Four end corners on the outer surface of the guide sleeve 23 are each fixedly provided with a support rod, and the other end of the support rod is fixed to the inner wall of the metal housing 17. Through the guide sleeve 23 movably sleeved on the outer surface of the second push rod 22, the guide sleeve 23 itself can only move up and down while keeping upright.

[0039] When revolving around the connection point between the concave-shaped rotating shaft 19 and the stepping motor 18, the second push rod 22 connected to it through the first push rod 21 will move up and down cyclically. The second push rod 22 moving up and down cyclically can drive the lower pressing plate 24 fixed to it to move downward together. The downward moving lower pressing plate 24 will contact the fruits and vegetables floating on the water surface and push them into the interior of the water source. Through the above technical solution, the fruits and vegetables floating on the water surface are pressed into the interior of the water source multiple times, thereby improving the cleaning effect of the device on lighter or hollow fruits and vegetables.

[0040] The through hole 25 located on the outer surface of the lower pressing plate 24 can reduce the resistance when the lower pressing plate 24 moves into the interior of the water source;

[0041] The arc-shaped groove 26 located on the lower end surface of the lower pressing plate 24 can hold the fruits and vegetables pressed into the interior of the water source, preventing them from moving left and right due to the downward pressure and ultimately causing a relatively violent impact between the fruits and vegetables;

[0042] The two inclined side plates 27 respectively fixed on both sides of the outer surface of the lower pressing plate 24 can prevent fruits and vegetables from moving to the upper end surface of the lower pressing plate 24 during the downward movement of the lower pressing plate 24.

[0043] A protective cover plate is provided behind the stepping motor 18 on the outer surface of the metal housing 17, and the metal housing 17 and the protective cover plate are fixed by screws; the protective cover plate can protect the stepping motor 18, and when the stepping motor 18 fails, the protective cover plate can be removed to repair the stepping motor 18.

[0044] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
