[0002] With the continuous development of the cleaning industry, more and more industries and companies require the use of ultrasonic cleaners. Ultrasonic cleaners are widely used to clean hardware, die heads, automobiles, jewelry, medical devices, electronic and electrical components, semiconductors, and more. After cleaning in an ultrasonic cleaner, the items (i.e., the items to be dried) are usually dried using a hot air drying device. Specifically, the air supplied by the blower is heated by an air heater and then enters the drying chamber, blowing towards the items to be dried inside the drying chamber, thereby drying the items.

[0003] However, the air inlet is mostly set at the top / bottom of the drying box. During the process of hot air blowing the items to be dried from top to bottom / bottom to top, there will be a problem of uneven drying speed in different areas of the items to be dried. Specifically, the drying speed of the area close to the air inlet is significantly faster than that of the area far from the air inlet. Utility Model Content

Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0034] The following combination Figures 1 to 8 , describing the embodiments of the present utility model.

[0035] Example 1

[0036] The present embodiment provides a rotary air drying device 6, comprising an air drying box 61 and a supporting platform 62. An air inlet (not shown) and an air outlet (not shown) spaced apart from the air inlet are provided on the wall of the air drying box 61. The air inlet is suitable for allowing an air inlet pipe 64 to pass through to enter the air drying box 61. The supporting platform 62 (such as Figure 4 As shown) is installed in the air drying box 61, for placing the workpiece to be dried 7 (as shown) Figure 8 As shown), the supporting platform 62 can be driven by the driving mechanism 691 to rotate around its own axis to drive the to-be-dried workpiece 7 to rotate, wherein the wind entering the air drying box 61 from the air inlet pipe blows toward the to-be-dried workpiece 7.

[0037] The rotary air-drying device 6 provided by the present invention has a supporting platform 62 that can rotate around its own axis, thereby driving the workpiece 7 to be dried placed on the supporting platform 62 to rotate synchronously, so that different parts of the workpiece 7 to be dried are taken turns to approach the air inlet position, thereby improving the uniformity of the drying speed of different areas on the workpiece 7 to be dried, reducing the area of the drying dead corner area, and improving the drying efficiency.

[0038] In this embodiment, the air drying box 61 is a rectangular structure, with an openable and closable box cover 611 on the top, and a handle 6111 on the box cover 611 for conveniently pulling the box cover 611. The rotary air drying device 6 also includes an air drying basket 612. The parts to be dried 7 are placed in the air drying basket 612, and the air drying basket 612 is placed on the supporting platform 62. The air inlet is opened on the bottom wall of the air drying box 61, and the air outlet is opened on the top of the side wall of the air drying box 61. The exhaust duct 65 is plugged into the exhaust outlet, and the lowest position of the exhaust duct 65 at one end in the air drying box 61 is higher than the position of the top of the air drying basket 612 to ensure the drying efficiency, and the air is discharged outward to maintain the pressure balance in the air drying box 61.

[0039] In an optional embodiment, an air knife 63 is installed within the air drying box 61. The air knife 63 is connected to one end of the air inlet pipe 64 located within the air drying box 61, with the air outlet slit 631 of the air knife 63 facing the surface of the drying object 7. Compared to a design in which air enters the air drying box 61 directly from the air inlet pipe 64 and blows toward the drying object 7, the installation of the air knife 63 increases air pressure and velocity, thereby improving drying efficiency. Specifically, the air knife 63 is connected to the air inlet pipe 64 via a quick-connect flange 633.

[0040] In an optional embodiment, the air knife 63 is vertically arranged. The vertically arranged air knife 63 can increase the wind-receiving area on the drying object 7, improve the drying efficiency, and adapt to the drying objects 7 at different heights, thereby improving the adaptability of the rotary air drying device 6.

[0041] In an optional embodiment, as Figure 5 As shown, the wind knife 63 is equipped with an air distribution plate 632. The air distribution plate 632 is provided with a plurality of air distribution holes 6321 spaced apart along the length of the air outlet slit 631. The air distribution holes 6321 discharge air toward the air outlet slit 631. Specifically, the air distribution holes 6321 are waist-shaped holes. The provision of the air distribution holes 6321 ensures a more uniform air volume exiting the air outlet slit 631. The provision of the air distribution plate 632 ensures that the air exiting the air outlet slit 631 is more uniform along the length of the air outlet slit 631.

[0042] In an optional embodiment, the number of the air knives 63 is four, such as Figure 4 As shown, the four air knives 63 are symmetrically distributed in two groups of diagonal positions. Correspondingly, the air inlet pipe 64 includes a main air duct 641 and four branch air ducts 642. The air knife 63 is connected to one end of the branch air duct 642 located in the air drying box 61, and the ends of the four branch air ducts 642 away from the air knife 63 are respectively connected to the main air duct 641, so as to divide the wind into four paths and supply them to the four air knives 63. Of course, there can also be two air knives 63, and the two air knives 63 are symmetrically arranged about the axis of the supporting platform 62, and the branch air ducts 642 are two, or there can be three or more air knives 63, and the branch air ducts 642 are three or more, and three or more air knives 63 are arranged at equal intervals around the axis of the supporting platform 62. Such a design can dry the items to be dried 7 from different directions at the same time, thereby improving the drying efficiency and further improving the uniformity of the drying speed.

[0043] In an optional embodiment, a filtering structure 68 is further included to filter the air entering the air drying box 61, thereby improving the cleanliness of the surface of the workpiece 7 to be dried and reducing the negative impact of impurities in the air on the cleanliness of the surface of the workpiece 7 to be dried.

[0044] In an optional embodiment, a blower 66 is further included, and an air outlet of the blower 66 is connected to an end of the air inlet pipe 64 away from the air knife 63 .

[0045] Regarding the location of the filter structure 68, in this embodiment, the filter structure 68 is located at the air inlet of the blower 66. Of course, the filter structure 68 can also be located at the air outlet of the blower 66 and / or on the air inlet duct 64. Compared to locating the filter structure 68 at the air outlet of the blower 66 or on the air inlet duct 64, locating the filter structure 68 at the air inlet of the blower 66 is more convenient and also facilitates subsequent maintenance and replacement of the filter structure 68.

[0046] In an optional embodiment, an air heater 67 is further included, connected between the air drying box 61 and the blower 66. The air heater 67 is used to heat the air exiting the air outlet of the blower 66. The air heater 67 heats the air exiting the air outlet of the blower 66, thereby heating the air entering the air drying box 61. The hot air helps improve the drying efficiency. Of course, the air used for air drying can also be cool air.

[0047] In an optional embodiment, as Figure 3 As shown, the rotary air-drying device 6 also includes a rotating shaft 692 and an angular contact bearing 693. The output shaft of the driving mechanism 691 is fixedly connected to the supporting platform 62 via the rotating shaft 692. The rotating shaft 692 is mounted in a mounting hole (not shown) on the bottom wall of the air-drying box 61 via the angular contact bearing 693. The angular contact bearing 693 provides rotational support for the rotating shaft 692. The angular contact bearing 693 has a better load-bearing capacity than ordinary deep groove ball bearings.

[0048] The following describes the process of air-drying the workpiece 7 using the rotary drying device provided by the utility model:

[0049] Place the workpiece 7 to be dried in the air-drying basket 612, open the cover 611 of the air-drying box 61, and place the air-drying basket 612 containing the workpiece 7 to be dried on the supporting platform 62;

[0050] Start the blower 66 and the air heater 67. The air is filtered by the filter structure 68 at the air inlet of the blower 66 and then enters the air heater 67. After being heated by the air heater 67, the hot air flows along the air inlet pipe 64 and enters the air knife 63. Inside the air knife 63, the hot air is evenly distributed by the air plate 632 and then blown out from the air outlet slit 631 at high speed to the surface of the workpiece 7 to be dried. In the fluid simulation, a certain flow of air is blown into the air knife 63. The movement trend of the air is as follows: Figure 7 As shown, from Figure 7 As can be seen from the figure, the air is indeed accelerated after passing through the air outlet slits 631, thereby achieving a better air-drying effect;

[0051] At the same time, the driving mechanism 691 is started, and the supporting platform 62 is driven to rotate through the rotating shaft 692, thereby driving the workpiece 7 to rotate continuously, so that different parts of the workpiece 7 are taken turns to approach the air inlet position, thereby improving the uniformity of the drying speed of different areas on the workpiece, reducing the area of the air drying dead corner area, and improving the drying efficiency. Figure 4 The fluid simulation diagram of the air drying box 61 is shown as follows: Figure 8 shown.

[0054] The cleaning system provided by the present invention includes the rotary air-drying device 6 and has the same effect as the rotary air-drying device 6, which will not be described in detail here.

[0055] Specifically, the cleaning system includes a frame 1, and a cleaning device and a rotary air-drying device 6 are both installed on the frame 1.
