DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0031] Example 1

[0032] This embodiment provides a down disinfection pretreatment device, including a treatment box 1 and a down feeding and receiving unit 4. The treatment box 1 is provided with an inner filter cartridge 6. In addition, the outside of the treatment box 1 is provided with a pipeline structure for gas discharge and waste liquid discharge.

[0033] The equipment structure also includes a heating unit 2 whose air supply end extends into the inner filter cartridge 6. Specifically, Figure 1 , 4 As shown, the heating unit 2 includes a heat-insulating shell 21 connecting the processing box 1 and the atomizing air supply unit 3, and an electric heater 22 and a delivery pipe 23 extending into the inner filter cartridge 6 at the outlet end are arranged inside the heat-insulating shell 21. When in use, the gas or atomized particles entering the heating chamber of the heating unit 2 are heated to form high-temperature steam through the heating function of the electric heater 22. The temperature of the steam is set and adjusted by the temperature controller of the electric heater 22 according to the steam temperature required for down disinfection (generally between 100-130°C);

[0034] The equipment structure also includes a connecting tube 7 which is arranged through the inner filter cartridge 6 and extends into the heating unit 2 at one end. The connecting tube 7 can serve as a supporting structure of the inner filter cartridge 6 to ensure the structural stability of the inner filter cartridge 6 in the treatment box 1.

[0035] The device structure also includes an atomizing air supply unit 3 with a liquid suction structure rotating inside, and the end of the liquid suction structure facing the heating unit 2 is movably plugged with the connecting tube 7, and a movable air port connected to the heating chamber of the heating unit 2 is reserved at the connection between the liquid suction structure and the connecting tube 7;

[0036] Specifically, Figure 1-3 As shown, the atomizing air supply unit 3 includes a liquid storage tank 31, an air inlet pipe 33 for inputting compressed air arranged in the middle of one side of the liquid storage tank 31, a liquid inlet pipe 35 arranged in the middle and lower part of one side of the liquid storage tank 31, and a two-way air valve 36 arranged at the top of the liquid storage tank 31. The liquid suction structure includes a vertical cylinder 32 arranged inside the liquid storage tank 31, and the structure between the vertical cylinder 32 and the liquid storage tank 31 is rotatably arranged. One end of the air inlet pipe 33 extends into the vertical cylinder 32, and a liquid suction disc 34 is provided on the lower end surface of the vertical cylinder 32 near the air inlet pipe 33, and a partition 37 is provided on the outside of the vertical cylinder 32 in a vertical position with the liquid suction disc 34. The partition 37 divides the liquid storage tank 31 into an upper and lower part. The shape of the liquid storage tank 31 is preferably cylindrical, and the highest working water level in the liquid storage tank 31 is controlled below the height of the partition 37.

[0037] The device also includes an adjustment conversion unit 5 arranged at the other end of the connecting tube 7. Specifically, the adjustment conversion unit 5 includes a rotating seat 52, a movable plate 54 arranged at one end of the connecting tube 7 away from the atomizing air supply unit 3, and a transmission member 51 connected to the rotating seat 52 at the transmission end. In the present embodiment, the movable plate 54 and the rotating seat 52 are fixedly connected, and the connecting tube 7 is connected to the rotating seat 52 through the movable plate 54. In addition, the transmission member 51 in the present embodiment is specifically two gears that cooperate with each other in transmission. One gear is axially connected to an external driving source such as an output shaft of a driving motor, and the other gear is axially connected to the rotating seat 52. The two gears are driven by the driving motor to drive the rotating seat 52 to rotate.

[0038] In this embodiment, if Figure 1 As shown, the structure of the down feeding and collecting unit 4 includes a pump assembly 41, a down feeding tube 42, a down collecting tube 43, a down inlet tube 44 and a down outlet tube 45. In order to meet the down feeding and collecting needs, the pump assembly 41 is provided with two conveying pump units, wherein the inlet and outlet of one conveying pump unit are connected to the down inlet tube 44 and the down feeding tube 42, and the inlet and outlet of the other conveying pump unit are connected to the down collecting tube 43 and the down outlet tube 45. The down feeding and collecting unit 4 with the above structure can deliver the down to be processed into the inner filter cartridge 6, and extract the processed down from the inner filter cartridge 6.

[0039] When the down jacket disinfection pretreatment device is actually used, first, clean water is injected into the liquid storage tank 31 through the liquid inlet pipe 35. To ensure the stability of the device during operation, the liquid inlet pipe 35 also includes a valve for opening and closing. Then, the down to be disinfected is filled into the inner filter cartridge 6 in the treatment box 1 by using the down feeding and receiving unit 4;

[0040] When the equipment is working, the tank liquid 31 remains stationary, and the regulating conversion unit 5 drives the connecting tube 7 to rotate, driving the vertical tube 32 movably connected to the connecting tube 7 to rotate relative to the liquid storage tank 31 so that the suction plate 34 connected to the vertical tube 32 rotates and extends into the clean water stored in the lower section of the liquid storage tank 31. Subsequently, the compressed gas is controlled to enter from the air inlet pipe 33 of the atomizing air supply unit 3, and the negative pressure generated by the high-speed air flow causes the clean water to be sucked out through the suction plate 34 and sprayed to the connecting tube 7. Due to the obstruction of the end of the connecting tube 7, the air flow splashes around with the liquid to form mist particles, which enter the heating chamber of the heating unit 2 through the active air port and are heated to generate high-temperature steam. The high-temperature steam is supplied to the inner filter tube 6 to perform high-temperature steam disinfection on the down.

[0041] After the high-temperature steam sterilization operation is completed, at this time, the down in the inner filter cartridge 6 has a certain moisture content and will be relatively attached to the cylinder wall of the inner filter cartridge 6, which is not conducive to unloading and requires subsequent drying operations. At this time, the conversion unit 5 is adjusted to drive the connecting cylinder 7 to rotate so that the suction plate 34 connected to the vertical cylinder 32 is rotated to the position of the two-way air valve 36 at the upper end of the liquid storage tank 31. At this time, after the compressed gas enters from the air inlet of the atomizing air supply unit 3, although the high-speed airflow generates negative pressure, since the suction plate 34 is not inserted into the clean water, liquid cannot be supplied. Under the action of negative pressure, the suction plate 34 absorbs the external airflow through the two-way air valve 36, and enters the heating chamber of the heating unit 2 through the active air port to be heated to form high-temperature gas. The high-temperature gas is a dry gas. After being supplied to the inner filter cartridge 6, the down can be dried. Finally, after the down drying operation is completed, the down is in a fluffy state. At this time, the down feeding and receiving unit 4 can be used to easily extract the down from the inner filter cartridge 6 for unloading.

[0042] Example 2

[0043] On the basis of Example 1, the structures of the atomizing air supply unit 3 and the regulating conversion unit 5 are further optimized, wherein a plurality of slots 39 are evenly provided at one end of the vertical tube 32 facing the connecting tube 7, and a connecting piece 9 connected to the connecting tube 7 is movably inserted in the slot 39, and a rubber pad 38 is provided at one end of the vertical tube 32 facing the connecting tube 7. The structure of the regulating conversion unit 5 also includes a cylinder group 1 53 arranged on a rotating seat 52 and having a piston end connected to a movable plate 54, and the rotating seat 52 and the movable plate 54 are connected in a movable manner.

[0044] When disinfecting the down, the down is often subjected to the corresponding operations of scenting and removing odor. At this time, the relevant treatment agent can be added to the liquid storage tank 31. The specific operation is to first drive the movable plate 54 through the cylinder group 1 53 to drive the connecting tube 7 to slide relative to the inner filter tube 6. At this time, the connecting piece 9 connected to one end of the connecting tube 7 is inserted into the slot 39 on the vertical tube 32, and the outside of the connecting tube 7 is in contact with the rubber pad 38 on the vertical tube 32, so that the movable air port is closed. At this time, the compressed gas enters the air inlet of the atomizing air supply unit 3 and enters the liquid storage tank 31 along the liquid suction plate 34, so as to evenly disperse the clean water and treatment agent in the liquid storage tank 31, thereby ensuring the mixing uniformity of the treatment liquid.

[0045] Then, when the down is disinfected and dried, the cylinder group 1 53 is controlled to be reset so that the active air port is opened.

[0046] Example 3

[0047] On the basis of Example 1 or 2, the outside of the processing box 1 is provided with a cylinder group 2 10 whose driving end is connected to the inner filter cartridge 6. The cylinder group 2 10 drives the inner filter cartridge 6 to move back and forth in the processing box 1. During the processing of the down inside the inner filter cartridge 6, the cylinder group 2 10 drives the inner filter cartridge 6 to move back and forth in the processing box 1, which can ensure that the high-temperature steam or high-temperature airflow is in full contact with the down in the inner filter cartridge 6 to a certain extent, ensuring the effect of the disinfection and drying operations. In addition, one end of the down feeding tube 42 and the down collecting tube 43 of the down feeding and collecting unit 4 extends into the inner filter cartridge 6. When filling and collecting down, the back and forth movement of the inner filter cartridge 6 helps to improve the filling and collecting efficiency. In addition. An electric heater 2 8 is provided inside the connecting tube 7 for assisting the drying operation of the down fed into the inner filter cartridge 6.

[0048] Example 4

[0049] Based on Example 1, this embodiment provides a method for using a down disinfection pretreatment device, comprising the following steps:

[0050] Step 1: Use the down feeding and receiving unit 4 to fill the down to be sterilized into the inner filter cartridge 6 in the treatment box 1;

[0051] Step 2: adjust the conversion unit 5 to drive the liquid absorption end of the liquid absorption structure to extend into the liquid storage chamber of the atomizing air supply unit 3, and the compressed gas enters from the air inlet of the atomizing air supply unit 3. The negative pressure generated by the high-speed airflow causes the liquid absorption structure to absorb the liquid and spray it to the connecting tube 7 to splash around to form mist particles, which enter the heating chamber of the heating unit 2 through the active air port and are heated to generate high-temperature steam. The high-temperature steam is supplied to the inner filter tube 6 to perform high-temperature steam disinfection on the down;

[0052] Step 3: After the high-temperature steam sterilization operation is completed, the conversion unit 5 is adjusted to drive the liquid absorption structure to rotate so that the liquid absorption end is separated from the liquid storage chamber of the atomizing air supply unit 3, and the compressed gas enters from the air inlet of the atomizing air supply unit 3, and the high-speed airflow enters the heating chamber of the heating unit 2 through the active air port to be heated to form high-temperature gas, and the high-temperature gas is supplied to the inner filter cartridge 6 to dry the down;

[0053] Step 4: After the drying operation is completed, the down is extracted from the inner filter cartridge 6 using the down feeding and receiving unit 4 .

[0054] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
